SingleRAN Solution Highlights Summary

Huawei‟s SingleRAN solution is an industry first, unique convergent solution for operators who run more than one network, especially for GSM/UMTS multi-mode network. It is a series of future-oriented and convergent network solutions (such as Multi-mode BSC, SingleBTS, IP RAN, GSM/UMTS inter-working algorithm, etc.) in relation to network architecture, transmission, facilities and O&M system. SingleRAN makes the technology choices and network evolution simple and greatly reduce access to the site, the equipment room building, transmission and other ancillary costs of the OPEX.

Huawei‟s SingleRAN solution embraces three essential elements (Uni -equipment, Uni-site and Uni-operation):

Figure 1 Key Figures of SingleRAN 

Uni-equipment: “One Network” Guarantee Flexible Evolution & Investment Protection

SingleBTS: SingleBTS (also known as 2G/3G integrated SingleBTS) makes Uni-site (Co-transmission & Co-auxiliary facilities) a reality. The modular and multi- mode design of Huawei‟s SingleBTS, supporting 2G and 3G in one compact cabinet, presents the ultimate solution. With its integrated SDR and MCPA technologies (software defined radio and multiple carrier power amplifiers), the SingleBTS also supports software upgrades from GSM to UMTS on a single module

– protecting operators‟ earlier investments in exist ing GSM equipment and sharply reducing the time of UMTS deployment.

Figure 2 Huawei SingleRAN BTS Expansion and Evolution

MBSC: MBSC (also known as integrated BSC/RNC) makes Uni-Operation a reality. Huawei‟s solution provides the integration of GSM BSC and UMTS RNC into a multi-mode BSC (MBSC). MBSC is designed with the unified PARC platform, which can support 2G and 3G in the same cabinet and provide IP/TDM dual-switching plane. 2G and 3G can share many boards in MBSC, thus it saves a lot in spare management. Furthermore, SingleRAN solution is compatible with technologies evolution to guarantee long term viability. All of its products are ready to evolve to LTE system.

Uni-site: “One Deployment” Bring TCO Saving

Co-Transmission With Huawei‟s multi-mode BSC and the SingleBTS, transmission sharing is

achievable within the system and allows future service convergence. The value of Huawei‟s dual

stack transmission mechanism for ATM and IP, and hybrid transmission and clock synchronization over IP, translates into ultimately smooth and flexible network evolution.

Figure 4 Co-Transmission Reduces Transmission Cost

Co-Auxiliary Facilities With SingleBTS, operators deploy multi-mode networks by one time and both GSM and UMTS networks can share the same facilities, such as cabinet, antenna system, feeder system, power system, battery and etc.

Figure 5 Reuse Antenna System

With one time deployment, operators can now reduce not only cost (footprint saving brings less lend cost, one time deployment brings less engineering cost), but also the time previously spent on construction and deployment. 

Uni-operation: “One Team” Improve Network Performance and Maintenance Efficiency

Co-OAM (operation and maintenance) combines all operations on one platform to facilitate network operation and maintenance most. By one team, human resources efficiency is largely optimized. Around 30-40% cost can be saved in NOC and field operation, spare parts management and network performance optimization by incorporative operation.

Figure 6 Co-OAM

Co-RNP/RNO (Radio network planning & optimization) allows constant 2G/3G network performance monitoring for further analysis. Project sharing, joint parameter management and common tools are used for multi-mode network planning and optimization (coverage, capability, and

neighboring cell) to realize high quality of “one network”.

Figure 7 Co-RNP/RNO

With Co-RRM (Radio Resource Management) RNC and BSC are unified as one network element and Co-RRM function is core network- independent. Co-RRM auto-allocates radio resources between 2G and 3G networks based on service and load. Data service throughput improves by as much as 25%. SingleRAN solution dynamically allocates radio resources to ensure the most optimal usage, which results in 10% handover.

Figure 8 Co-RRM

With Co-TRM (Transmission Resource Management), transmission sharing can be implemented for both voice and data services, guaranteeing QoS and improving transmission efficiency up to 10%.

Figure 9 Co-TRM

Huawei‟s pioneering SingleRAN solution can support GSM/UMTS/LTE simul taneously, which will help the operator to realize one network for multi-mode, and a single OMC can support the management of multi-mode networks. All these features can facilitate our customer in great amount to cut off their TCO drastically. Allowing operators a first-time opportunity of truly deriving those

ultimate benefits, Huawei‟s SingleRAN solution will help operators establish a “maintenance -easy” infrastructure so that operators can focus on market. With an enhanced single service platform, quality of service can be maintained, new applications quickly introduced, and ARPU increased, and

competitive strengths enhanced. Huawei‟s SingleRAN truly affords our expanding wireless world a viable solution that is “One For All.” 

3. Network Proposal for VMS 3.1 Requirement Analysis 3.1.1

Summary of Requirement

As one of the top three major mobile communication operators in Vietnam, VMS is facing fierce competition and long-term challenge in the matured 2G mobile market. Undoubtedly, introduction to 3G is able to stimulate service to keep VMS in the leading position. However, with the coexistence of multiple network technologies, it demands VMS to construct separate networks leading to increased OPEX and CAPEX. In this proposal, Huawei offers SingleRAN solution which can integrate the functions of the GSM and UMTS, and provide the highest capacity with the smallest footprint in the market. It is also able to enhance the service coverage and to meet increasing mobile broadband demand in Vietnam. With one purchase decision, VMS can now realize the optimal benefits of ownership from a cost and time efficient solution for multiple network investment protection, enhanced performance, reduced OPEX and CAPEX, and improved TCO. Huawei has been the supplier in Vietnam telecommunications market for more than nine years, which is one of the experienced players in the telecommunication to promise innovative technologies and cost- effective solutions. Based on Huawei‟s understanding

of Vietnam market, studying the requirement documents and VMS‟s network environments, Huawei is convinced to have ability to fulfill VMS requirements in such aspects as below: 

Construct a 2G/3G SingleRAN system including 2G/3G integrated SingleBTS equipment, BSC/RNC equipment and uniform OMC system for VMS Center I

and V. 

Maximum output static power of each GSM TRX measured at the top of cabinet (TOC) must be at least 20W; Maximum output static power of each UMTS carrier measured at the top of cabinet (TOC) must be at least 20W.



The proposed 2G/3G integrated SingleBTS is configured with singleband GSM900 S4/4/4 or dualband GSM900 S2/2/2 + GSM1800 S2/2/2 or distributed GSM900 S4/4/4, and distributed WCDMA S2/2/2 (Band 2100M, 384CE UL/ 384CE DL, HSDPA+ 21Mbps per cell, HSUPA 5.76Mbps per cell).



Fast deploy a complete GSM/UMTS network, save time-to-market, to gain competitive edge in Vietnam market by cooperating with vendor who have strong local presence and hold a good track record of accomplishment in Vietnam.



The proposed SingleRAN equipment is hardware ready for IP RAN to realize All-IP solution in near future.



Offered network elements for this northern region include 1160 2G/3G integrated SingleBTSs (570 for Center I and 590 for Center V), 11 integrated BSC/RNCs (5 for Center I and 6 for Center V), 2 OMC-R (1 OMC-R for each Center I and V),

Page 17 of 155


230 sets of additional materials for split and re-installation (200 sets for Center I and 30 sets for Center V), 33 Transport Nodes for supporting transmission between NodeB and RNC (15 for Center I and 18 for Center V), 2 sets of Management System for Transport Nodes (1 Transport Node Management System for each Center I and V), and related installation accessories. 

The proposed network flexibly and smoothly evolves to HSPA+ supporting downlink of 21 Mbps, HSPA+ Phase 2 supporting downlink of 42 Mbps and LTE system in future.

3.1.2

Subscriber Distribution

From VMS‟s 2G subscriber number requirement, the total subscriber number for Center I is given as 2.3 Million while the total subscriber number for Center V is given as 2.2 Million. Therefore the northern region (Center I and Center V) has total subscriber number of 4.5 Million. However, in order to meet VMS‟s minimum requirement of 2048 TRXs as well as the 30% capacity redundancy, the maximum total subscriber for 5 BSC in Center I is dimensioned and supported up to 2.88 million (subs) while the maximum total subscriber for 6 BSC in Center V is dimensioned and supported up to 3.45 million

(subs) . Therefore, the total subscriber number for the northern region (total 11 BSCs for Center I and V) is approximately 6.33 million subscribers where is much higher than the given total subscriber for the Northern region.. For 3G, the total subscribers number given in Center I is 2 million (sub) while the total subscribers number given in Center V is 1.8 million (sub) respectively based on the

VMS‟s requirement. From the details obtained from VMS‟s RFP requireme nt, there are total 11 integrated BSC/RNC in Center I and Center V which is 5 integrated BSC/RNC for Center I and 6 integrated BSC/RNC for Center V. By assigning the total subscriber number evenly in each integrated BSC/RNC for Center I and Center V, the subscriber number is equals to 400,000 (3G sub) for Center I and 300,000 (3G sub) for Center V.

Furthermore, the VMS‟s minimum requirements of 3Gbps total throughput, at least 300 NodeBs/900 Cells as well as the 35% capacity redundancy for each integrated BSC/RNC are fulfilled.

3.2 Construction Strategy Taking into account the challenges VMS faces in the Vietnam market, Huawei would like to present the following compelling business propositions which are able to deliver the best business values to VMS: 

Adopt 2G/3G integrated SingleBTS equipment (also known as SingleBTS) that is able to support SDR (Software Defined Radio). Its RF module can migrate from GSM to UMTS and then to LTE in 900MHz GSM frequency band, from GSM to LTE in 1800MHz GSM frequency band, and from UMTS to LTE in 2100MHz UMTS frequency band only by software upgrade without any radio hardware replacement. It allows flexible configuration between 2G and 3G and can be smoothly evolved to LTE.



Propose Huawei MRFU with total 80W output power supports 6 TRX/MRFU in GSM only and 4 carriers/MRFU in UMTS only and flexible configuration between GSM and UMTS. It supports static 20W TOC power in case of S4 configuration due to total 80W output power per MRFU for one cell for SingleBTS 2G RF. For SingleBTS 3G RF, it supports 20W power in case of S3 configuration due to total 60W output power per RRU3804 for one cell.



Adopt SingleBTS that is based on new technologies including MCPA design and DPD and Doherty technology both in 2G and 3G parts to enhance PA efficiency to 40% both in 2G and 3G part. It also supports maximum 6TRX per 2G MRFU unit and 4 carriers per 3G 3804 unit so that can support future expansion to 12/12/12 GSM (6/6/6 GSM900 + 6/6/6 GSM1800) and 3/3/3 UMTS configuration. Besides, the proposed SingleBTS 3G NodeB supports 384/384(DL/UL) CE both in hardware and software license.



All of Huawei‟s SingleBTS offered to VMS GSM/UMTS network support full performance EDGE, HSDPA and HSUPA before CLR (Commercial Launch

Ready) to meet VMS‟s mobile broadband requirements. It supports HSPA+ with the maximum peak rate up to DL 21 Mbps / UL 5.76 Mbps per cell and supports HSPA+ Phase 2 (DL 42Mbps / UL 11Mbps) through upgrading. 

Propose interface of TDM/E1, ATM/E1 and IP/FE and GE solution for SingleBTS. In

addition

to

TDM/E1

synchronization

solution,

IP

Clock

(1588V2)

synchronization solution is proposed for SingleBTS to get clock signaling from

VMS‟s ME+ network. 

Deploy distributed DBS that could save more than 30% of Total Cost of Ownership (TCO) including cost of site location, equipment installing, power

consumption, TMA, maintenance etc. Huawei‟s DBS3900 includes two parts, BBU and RRU. With different integrated methods of BBU and RRU, Distributed BTS can fit for different application scenarios. 

2G/3G Smooth Evolution – The 3G and IP based design can ensure the GSM system evolves to the 3G system easily. For instance, Huawei BSC shares the

same hardware platform with Huawei RNC. VMS can upgrade from BSC to RNC according to capacity requirements flexibly and smoothly. The 2G BTS can also support 2G/3G co-cabinet (or 2G/3G dual mode).

TDM/IP Co-transmission,

Co-OM, Co-RNP/RNO, Co-RRM, Future proof design to protect VMS initial investment. 

Deploy large capacity integrated BSC/RNC (also known as MBSC) to decrease the number of network elements, simplify network topology, allows easy maintenance that result in reduced OPEX. Its high packet throughput can fully meet the traffic requirements of EDGE/HSDPA/HSUPA. It can support up to 4096 TRX per BSC (PCU embedded) with standalone TC, and up to 12Gbps per RNC.



Propose three kinds of power supply to meet the power requirement for different equipment individually including indoor and outdoor BTS, BSC, TC and Transporting Node. The proposed battery and power systems are based on the maximum load design with N+1 redundancy in rectifier module and 6 hours backup time in battery.



Adopt large capacity for OMC-R by offering one OMC-R for each center. It can manage 2G/3G simultaneously and support all IP connections.



Deploy OSN7500 at hub-site transport node and OSN7500+NE40E at RNC-site transport node. OSN7500 is offered as the SDH layer equipment, and NE40E is offered as packet layer equipment.

Huawei hopes that the above principles are suitable and beneficial for VMS project. Huawei looks forward to working closely with VMS to generate the final solution that concur with the requirements specified.

Note: Configuration separated power system and battery for 2G/3G integrated SingleBTS system, integrated BSC/RNC, TC, and Transport Node, antenna & feeder are included accordingly.

3.3.1.1

2G/3G Integrated SingleBTS

In this proposal, Huawei offers three types of 2G/3G integrated SingleBTS solutions to

meet VMS‟ requirement. All offered 2G/3G integrated SingleBTS support IP over E1, FE and GE hybrid transmission as well as IP with ATM dual stack transmission. Each 2G/3G integrated SingleBTS is configured with 8 E1, 2 electrical FE and 2 optical GE in the transmission interface.

3.3.1.2

2G/3G Integrated BSC

Each BSC is dimensioned with STM-1 and optical GE interfaces for interconnection with 2G BTSs. Each RNC is dimensioned with STM-1 and optical GE interfaces for interconnection with 3G NodeBs. Considering that the BSC and RNC need to inter-work with the existing Core Network equipment from other vendors, A interface is designed with FE interface, and IuCS interface is designed with both STM- 1 and GE interface, and Gb interface is designed with both optical FE and E1, and IuPS interface is designed with both optical GE and STM-1 interface for VMS flexible deployment.

3.3.1.3

OMC-R and PRS server

One OMC-R server and one PRS server are configured to each Center I and V in order to manage all the integrated BSC/RNC. One O&M terminal and one alarm terminal are configured in the central room and remote room respectively.

3.3.1.4

GTCS (Transcoder)

Based on the requirement, TC is not embedded inside the BSC model, thus Huawei proposes standalone TC for each BSC, with total of 5 TCs for Center I and another 6 TCs for Center V. Besides, Huawei also proposes STM-1 for Ater interface and A

interface to meet VMS‟s requirement for the transmission purpose.

3.3.1.5

IP Clock Server

In order to achieve IP clock synchronization from integrated BSC/RNC side to 2G/3G integrated SingleBTS, two IP clock servers co-locating with the integrated BSC/RNC PURCHASING 2G/3G INTERGRATED BTS FOR MOBIFONE NETWORK 2010

3.3.2

Proposed Transmission Network For transmission network design, Huawei proposes OSN7500 as the Hub-sites transport Node and OSN7500+NE40E as the RNC-site transport nodes. In Hub-sites, OSN7500 will connect all the PDH and Ethernet service and convergence to STM-1, GE or 10GE services. In RNC-sites, OSN7500 will work as the SDH layer equipment to process all the PDH and SDH services. And NE40E will work as the packet layer equipment to process all the Ethernet services and provide L3 and IP routing functions. All the OSN7500 and NE40E will be managed by iManager U2000 system, each center of VMS will have one to manage the transmission node independently. Hub sites Transport Node

Proposed 2G/3G integrated SingleBTS Equipment

There are 3 types of models for 2G/3G integrated SingleBTS: For Macro Indoor GSM and Distributed WCDMA, Huawei proposes BTS3900 + DBS3900. For Macro Outdoor GSM and Distributed WCDMA, Huawei proposes BTS3900A + DBS3900. For Distributed GSM and Distributed WCDMA, Huawei proposes DBS3900 + DBS3900 With Distributed GSM and Distributed WCDMA, VMS can efficiently deploy a high-performance 3G network with a low TCO since The baseband processing unit (BBU) of DBS3900 is characterized by a small footprint, easy installation, and low power consumption. In addition, the BBU can be installed in the spare space of an existing site. The remote radio unit (RRU) of DBS3900 also has a compact design and light weight, and it can be installed close to the antenna to decrease feeder loss and improve system coverage performance. Macro Indoor/Outdoor GSM is for compact installation with smaller footprint, fewer module types, G/U co-cabinet capability and excellent expandability. The detailed specifications of each type of 2G/3G integrated SingleBTS are interpreted in the following table.

Proposed IP Clock Server Equipment

For IP clock server, Huawei proposes IPCLK1000. It uses the same service data transmission protocols as those for data transmission between the integrated BSC/RNC and the BTS/NodeB. While the integrated BSC/RNC and BTS/NodeB have embedded the function of IP Clock client, therefore, the introduction of IPCLK1000 has no additional requirements for topologies or for Qos performance of networks. Besides, it can be installed alone, in an integrated BSC/RNC cabinet or any other cabinet that is 300 mm in depth. In this proposal, Huawei provides one IP clock server for BSC and one IP clock server for RNC. Table 15

Offered 2G/3G Integrated SingleBTS RF Connection with Feeder and Antenna

The following diagram shows the RF part of interconnection between Macro/ Distributed 2G/3G integrated SingleBTS, antenna and feeder system. Considering Huawei‟s RFU/RRU can support 6 TRXs or 4 Carriers with just one unit of hardware, so the RF connection is very convenient, just one RF unit for one sector is enough, whatever regardless it is the Outdoor Macro BTS (BTS3900A), Indoor Macro BTS (BTS3900), Distributed BTS (DBS3900) or the Distributed NodeB (DBS3900).

Refer to the Table 51 and Table 52 as above: In Center I, with 30% redundancy, the TRX number calculated for each BSC model = 1368 * (100% + 30%) = 1779 TRX. In Center V, with 30% redundancy, the TRX number calculated for each BSC model = 1180 * (100% + 30%) = 1534 TRX. As stated stated in the tender tender document document,, the minimum minimum config configurat uration ion for each each BSC is to support 2048 TRXs. Since the TRX number for each BSC in Center I and Center V is still less than the minimum TRX requirement from VMS after considering the 30% redundancy, therefore, the TRX number is dimensioned and designed as 2048 TRXs for each BSC in Center I and Center V. 4.1.1.1

On the other hand, the minimum requirement for the RNC throughput is at least support up to 3Gbps capacity throughput, however, this throughput requirement cannot be met if the traffic parameter of PS throughput per sub is 152 bps. So, in order to meet the minimum requirement as mentioned as above, the traffic model for Center I and Center V are designed and dimensioned accordingly in adjusting the PS PURCHASING 2G/3G INTERGRATED BTS FOR MOBIFONE NETWORK 2010

Sun M5000 Single Server 

SUN M5000 (4CPU) maximum supports 190 essential NE.



50 Cells equals 1 essential NE for WCDMA and 125 TRXs equals to 1 essential NE for GSM.

Since the offered OMC-R server hardware can support up to 190 equivalent NEs, the maximum number of cells can be derived as the following: 

Maximum number of cells for RNC+Node B = 190 equivalent NEs x 50 cells/1 equivalent NE = 9,500 cells



Maximum number of TRXs for BSC+BTS = 190 equivalent NEs x 125 TRXs/1 equivalent NE = 23,750 TRX

Also considering the minimum requirement of the OMC capacity from VMS (the hardware of each OMC system must be dimensioned for supporting up to 10000 TRXs/5000 cells), the cell number for Center I is increased from 4,617 to 5,000 and the cell number for Center V is increased from 4,779 to 5,000. For the TRX dimensioning part, the TRX number for Center I is increased from 8,892 to 10,000 TRXs and the TRX number for Center V is increased from 9,204 to 10,000 TRXs. The final dimensioning result of OMC-R capacity requirement for Center I and V are listed as below: Table 84

On top of above dimensioning principle, the total cells numbers and total TRXs numbers of each OMC-R is 5000 Cells/10000 TRXs for Center I and 5000 Cells/10000 TRXs for Center V, thus the total essential NEs of each OMC-R can be calculated in the following formula: (Total Cells number / 50 Cells + Total TRXs number /125 TRX), where the total essential NEs is 180 for both Center I and Center V, which is smaller than 190, so the type of M5000 with 4CPU can support the particular capacity requirements, because it is hardware ready to support 9500 cells/23750 TRXs and 190 essential NEs.

In Center I & V, the OMC-R system is configured on 5000 TRXs/10000 Cells, Total essential NEs in PRS = 5000/62.5 + 10000/125 = 160 NE Since the offered PRS server hardware can support up to 800 equivalent NEs, the maximum number of cells can be derived as the following: 

Maximum number of cells = 800 equivalent NEs x 62.5 cells/1 equivalent NE = 50,000 cells

Multi-mode BSC

Figure 27 Multi-mode BSC 

Inherit unified platform

Huawei‟ multi-mode BSC6900 is based on self-developed PARC (Platform of Advanced Radio Controller) platform with IP/TDM dual-switching plane and high reliability. Because of

Huawei‟s durative R&D strategy, legacy BSC (BSC6000 for GSM&BSC6810 for UMTS) can be upgraded to BSC6900. 

First-in-class capacity and density

BSC6900 has a First-in-class capacity (5100Cells and 12Gbps throughput for UMTS only/4096TRXs for GSM only) in industry. BSC6900 has only 7 board types (excluded interface board), it saves a lot in spare management. This large capacity and multi-mode BSC not only provide a more flexible solution, but also meet the needs for the wireless broadband, which gre atly protect our customer‟s investment and being ready for the future technologies. 

TCO saving

The combined multi-mode BSC causes simple network architecture, less number of BSC is needed. Co-TRM with higher transmission efficiency saves huge amount of transmission resources, Co-RRM can balance the traffic between GSM and UMTS intelligently, and then switch off the idle carriers to save power consumption. Co-OAM with higher human resources efficiency brings OPEX saving. 

Multimode brings flexible configuration and uni-operation

To meet different networking requirements, BSC6900 can support GSM only or UMTS only or GSM/UMTS in same cabinet; share the same sub-rack and the same boards. The capacity of each mode can be transferred dynamically according to the trend of traffic.BSC6900 is a milestone of Multi-mode BSC, it supports Co-TRM, Co-RRM, Co-OAM, PURCHASING 2G/3G INTERGRATED BTS FOR MOBIFONE NETWORK 2010

Co-RNP, all these features benefits operators with not only TCO saving but also better network performance. 

Improve network performance through optimized Co-RRM algorithm

The Co-Radio Resource Management (Co-RRM) algorithm performs unified management and intelligent scheduling on the radio resources in the GSM network and UMTS network. As the traditional Co-RRM algorithm exchanges the 2G/3G load information between the GSM network and the UMTS network through signaling procedures across the core networks (CNs). The BSC6900 optimized Co-RRM algorithm enables rapid transmission of 2G/3G load information (used as internal messages) with an internal procedure. The advantages are as follows: 

Having no dependency on the equipment in the core network



Reducing latency, adjusting the load in real time, and increasing the success rate of inter-RAT handovers



Decreasing the signaling flow on the standard interface and saving interface resources

The optimized Co-RRM algorithm maximizes the sharing of radio resources between the GSM network and the UMTS network, thus increasing the network capacity.

Convergence

Figure 28 Module design BTS

Huawei SingleBTS 3900 series are based on self-developed platform HERT and adopt modular design. The 3900 series BTS include 3 parts, RRU (Remote Radio Unit)/RFU (Radio Frequency Unit)/BBU (Base Band Unit), which can be combined in different ways in order to adapt various scenarios. Modular design also simplifies the transportation, installation, maintenance of the BTS and the most significant is that the SingleBTS can support GSM/UMTS/LTE simultaneously.

Page 95 of 155


Figure 29 The SingleBTS Portfolio

To come across various capacity and coverage requirements of operator, Huawei delivers a comprehensive BTS family that includes the Macro BTS, Distributed BTS, Micro BTS, etc to achieve seamless coverage. It is convergent platform between different BTS portfolio as well as convergent platform between GSM, UMTS and LTE. 

Evolution

Figure 30 Huawei convergent BTS expansion and evolution

Cabinet based macro indoor BTS (BTS3900) and outdoor BTS (BTS3900A) is suitable for centralized installation as well as G/U multi-mode and multi-band scenarios. It can support 72TRXs for GSM or 24 cells for UMTS in all. The 3900 series multi-mode base stations provide multiple evolution solutions and support the evolution from GSM to UMTS and further to LTE. BBU can be reused when evolve to UMTS or LTE, only need to insert relative two sub-boards into BBU: WMPT or LMPT for control and transmission, WBBP or LBBP for baseband processing. 

Application of the SDR technology

With the SDR technology, RF modules can support any type of dual-mode among GSM, UMTS, and LTE in the same frequency thro ugh software update, so to meet operator‟s requirements that need fast and one-time deployment. 

Co-cabinet solution

RF modules serving different modes (includes SDR module) can be installed in the same cabinet so that the single-mode or any type of dual-mode among GSM, UMTS, and LTE is applicable to the base station. RF modules operating in different frequency bands can also be housed in the same cabinet. In this way, the multi-mode and multi-band application is available. 

Green

Stackable design makes it possible for hand carry installation and flexible expansion. The macro outdoor BTS (BTS3900A) can work stably in the range of -40 to +50 degree Celsius. Air direct-ventilation design makes it more reliable without air condition or heat-exchanger for temperature adjustment. It has the same baseband and radio performance with indoor macro BTS. Distributed BTS (DBS3900) separates traditional cabinet BTS into two parts, baseband unit (BBU) and remote radio unit (RRU). RRU can be mounted near the antenna to save feeder loss of 3 dB and TMA (Tower Mounted Amplifier). They mark small size, large capacity and high integration. Therefore, we can provide a zero footprint solution thus fulfilling the desire of easier, faster site acquisition, installation and network deployment. Huawei SingleBTS can support multiplicate methods on power control, there are two main kinds: 1. dynamically shut down idle resources, like cell, TRX and PSU boards, 2. allocate accurate power according to actual traffic requirement, like BCCH power optimization and power optimization based on channel type. Based on these advanced and innovative power control technologies, Huawei SingleBTS can bring extra 10-25% power consumption saving. High effective digital power amplifier (DPA) saves the electrical power cos t. With DPD+ A-Doherty technology, the PA efficiency is up to 40%. DBS3900 S111 typical power consumption is only 400W compared to the traditional common Node B of 1500W.

5.2 Multi-mode Solutions With the development of UMTS, more and more traditional GSM operators migrated to the UMTS network in order to provide high speed data service and carry superior service experience. Based on UMTS network, operators are able to launch more abundant and differentiated services to end users, and attract more subscribers. Meanwhile, UMTS network helps operators improve the ARPU and MOU, and keep leading in the market. With the evolution of GSM network to EDGE all over the world, GSM/EDGE and UMTS will co-exist for a long time, the inter-working and traffic balance between GSM/EDGE and UMTS is still significant For mobile operators, balancing the investment between GSM and UMTS and acquire most profit in GSM/UMTS deployment is becoming more important. Based on all theses requirements of our customer, Huawei would provide different multi-mode solutions to meet different needs in typical scenarios.

Figure 32 High Expansibility BBU3900

Thanks to Huawei‟s unified HERT platform, baseband module, BBU3900 can be applied in GSM or UMTS mode by plugging in different daughter card. Meanwhile, baseband and transmission can be expanded separately. It also can be sm oothly evolved to LTE by adding LTE baseband daughter card. Different combination of RF module and BBU3 900 realize two multi-mode solutions: Co-cabinet solution and SDR solution.

Meanwhile, baseband and transmission can expand separately.

5.2.2

Multi-mode Solution based on Software Defined Radio (SDR)

SDR is the abbreviation of “software defined radio”. It means taking the hardware as an unified platform, and re-program and reconstruct the equipment by software (Much of the waveforms, e.g., frequency, modulation/demodulation, coding, etc) to support multi-mode. The signal path can be reconfigured in software without requiring any hardware modifications. In conclusion, SDR is a new wireless framework based on DSP/FPGA and software. To be emphasized, the research of SDR technology is just in initial phase, SDR mentioned in this proposal is just for dual-mode in the same frequency.

SDR is considered as a trend for 3G and the evolution afterwards 3G by ITU. And it‟s gradually recognized by the industry for its smoothly evolution. Huawei keeps leading in SDR R&D, and has integrated series of SDR products including RRU3908 and MRFU covering 850 MHz/900 MHz/1800 MHz/1900 MHz. After Huawei deploy the 1

All these prove that Huawei SDR technology is mature and available for great scale deployment. SDR can be widely used for dual-mode network construction, e.g.: GSM&UMTS modernization, GSM900MHz refarming, GSM850M/1900MHz refarming, new network for future evolution. It can bring long-term TCO saving and has great advantage in smooth evolution, 

Abis Transmission Saving

1. Abis IP over E1/FE/GE Huawei provide Abis IP over E1/FE/GE to reduce transmission cost. Abis IP over FE/GE adapts to all IP development trend of future transport layer and protocol development. The Abis interface incorporates the features such as high bandwidth and low cost deployment, and it does not have any restrictions on the BSC capacity. The low IP network deployment cost, short construction period, and easy maintenance effectively reduce the CAPEX and OPEX of operators. Operator which owns transport network resources, Huawei proposes IP over E1 and TDM over E1. Thus, telecom operators can use the existing TDM network to protect the investment and reduce the transmission cost. 2. Abis MUX PURCHASING 2G/3G INTERGRATED BTS FOR MOBIFONE NETWORK 2010

Huawei Confidential

Page 104 of 155


Figure 43 Abis MUX

Abis MUX is used to save the bandwidth and multiplex the packets. The BSC and the BTS serve as transmitting end and receiving end of each other. When Abis MUX is applied, the transmitting end multiplexes the UDP packets that meet the multiplexing condition. Multiple UDP packets are multiplexed into one IP/UDP header at the transmitting end and then demultiplexed at the receiving end to reconstruct the original data in the IP/UDP packets. Thus, the transmission efficiency is improved and the bandwidth is saved. By multiplexing and demultiplexing the IP/UDP packet, Abis MUX reduces the overhead of each IP packet, increases the efficiency of the IP transmission, and saves the bandwidth. 3. BTS Local Switching Solution With BTS Local Switching solution, if the calling MS and called MS are within the coverage of the same BTS or BTS group, the BSC performs the loopback on the cabinet group of the convergent BTS, only the signaling is sent to BSC when the calling and called parties are under the same site. This feature helps save the local or long-distance transmission resources on the Abis and Ater interfaces.

Figure 44 BTS Local Switch Solution

4. Abis Congestion Triggered HR Allocation In heavy traffic hours, if the Abis transmission resources are not sufficient, the Abis transmission may be congested earlier than the air interface. The TCHF-to-TCHH conversion based on the air interface load and the mechanism of preferentially allocating TCHH cannot guarantee the system capacity. Based on the congestion status on the Abis interface, the Abis congestion triggered HR allocation function performs dynamic TCHF-TCHH conversion, preferentially allocates TCHH, and carries out queuing and pre-emption to ease the Abis interface congestion and to increase the system capacity. So this function can helps save the Abis transmission resources and reduce the network construction cost. PURCHASING 2G/3G INTERGRATED BTS FOR MOBIFONE NETWORK 2010

Page 106 of 155


Figure 47 TRX Power Amplifier Intelligent Shutdown

Using intelligent shutdown of TRX by time function, operator can specify a period of low traffic time. In this period, the BSC commands the BTS to shut down some TRXs in a cell. When the period ends, the BSC commands the BTS to switch on the TRXs. Likewise, intelligent shutdown of the idle TRX in time slot level and priority assignment of time slots in BCCH TRX decrease power load in PA. Hence, typical power consumption of BTS3900 (TOC=20W, load factor=30%) for S2/2/2 configuration is only 500W which is the leading value in the industry level. By this way, the power management and self-protection of the system is enhanced. Thus raises the reliability of the system and prolongs the life cycle of the product. 

In a 900 MHz/1800 MHz dual-band network, Dynamic Cell Power Off feature is generally used to save more power consumption. In a specified period, if the traffic is low and a 900 MHz cell can carry all the traffic in the coverage area of an 1800 MHz cell, then the 1800 MHz cell can be powered off to reduce the power consumption of the BTS. By powering off the idle network devices in low traffic hours, the consumption of resources can be reduced. This also reduces the operational expenditure of the operators.

Active Backup Power Control

Figure 49 Active Backup Power Control

Once the external power of the BTS is disrupted, the BTS uses the backup battery to supply the power. Huawei provide this function to gradually shut down the TRXs and decreases the transmit power of the TRX to prolong the service time of the BTS. This function decreases the power consumption of the BTS, prolongs the service time of the BTS, and decreases the out-of-service cell rate when the external power supply of the BTS is disrupted. And it also can increases the discharge time of the battery, saves the working time of the generator, and thus saves the cost of the power supply. 

PSU Smart Control The PSU (Power Supply Unit Module) intelligent shutdown function shuts down the redundant PSUs based on the BTS load on the condition that the required power consumption of the BTS is met. This function improves the efficiency of the power conversion, prolongs the working time and lifetime of the PSU, reduces the power consumption, and saves the operating cost.



Enhanced BCCH Power Consumption Optimization In traditional BTS, the transmit power of the main-BCCH carrier is fixed. Huawei Enhanced BCCH Power Consumption Optimization function can reduce the transmit power of the non-main BCCH timeslots on the main BCCH carrier to decrease the power consumption of the BTS.

Soft Synchronized Network

Figure 50 Network Synchronization

The Soft Synchronized Network is one of Huawei unique features. The software synchronized site can synchronize the BTS TDMA frame without GPS engineering. This feature is especially useful in two scenarios: high density traffic load area or limited frequency resource. Huawei could support Um interface software synchronization intra BSC and inter BSC without adding any additional hardware. As Figure 48 shows, before network synchronization, a center BTS should be identified. Here BS1 becomes the Center BTS. In the first round, BTSs surr ounding BS1 will be synchronized orderly, such as1-2, 1-3, 1- 4…1-7. In the second round, the already synchronized BTS become the Center BTS, synchronization among BTSs will carried out according to specific sequence, like 2-8, 2-9, 3-10, 3-11, 4- 12…7-19. Synchronization will repeat till all BTS are synchronized. For intra-BSC soft synchronization, the soft synch error is less than 1.5 bit, a pair of synch tuning time is less than 5sec, and a pair of synch info-collecting time is less than 5min. Synchronized network means that all the GSM BTSs are in same pace. It can improve the radio link quality by enhancing the ICC performance to 5~10dB, while co-existing with other technologies, tighter frequency reuse rate can be realized and network capacity can be increased. 

IBCA IBCA (Interference-Based Channel Allocation) is a dynamic frequency and channel allocation algorithm based on the prediction of the achievable CIR (Channel Interference Relation) of each candidate channel and established channel.

Figure 51 IBCA

Page 109 of 155


IBCA could be utilized under the condition where the spectrum resource is rare and dense frequency reuse brings severe inter-cell interference which in stead of channel limits the network capacity. IBCA bases on software synchronized network, no GPS needed, easy implementation. It lessens the over interference level in the network and provides more effective frequency reuse with ensured quality, thus the network capacity could be increased remarkably. 

Tight BCCH Frequency Reuse In order to improve spectrum efficiency, Huawei introduces the tight BCCH frequency reuse. The multiplexing mode of the BCCH frequency is changed from 4 x 3 to 3 x 3, thus three frequencies are added to the frequency hopping. After 1 x 1 frequency multiplexing is used, each cell can be added with one TRX and the system capacity can be improved by around 25%. For operators, just through enabling the function, the following benefits could be obtained.



Decreasing number of frequencies occupied by BCCH and improving spectrum frequency



Increasing available frequencies for TCH and frequencies for frequency hopping



Increasing frequencies for frequency hopping



Expanding the system capacity without adding new hardware



Saving the costs for adding sites and cells. The TCH channel on the BCCH frequency is used by the MSs near the BTS. The subscribers can obtain improved speech quality when this function is enabled.



The random access failures decrease and the access performance increases.

High TOC Output Power Huawei GSM BTS series also adopt Multi-carrier Radio Frequency Unit (GRFU). Each GRFU can serve as six TRXs. The max TOC power is 49.0dBm at GMSK mode or 47.2dBm at 8PSK mode respectively without any degradation of capacity or additional antenna systems.



High Receiving Sensitivity With the 3G RF design technology introduced, Huawei BTS has been improved in processing RF and baseband signals, particularly the performance of the baseband demodulation algorithm. So the static receive sensitivity of a single-channel reaches -113dBm, the uplink coverage of the GSM network can be improved up to 20% compared to the industry level with the receive sensitivity as -110dBm. Besides, 2-way receive sensitivity is -116dBm. Operators could further enlarge the uplink coverage just through software configuration.

Extended Coverage

CS: Extended Cell In GSM specifications, limited by timing advance (TA) 63 bit, the standard maximum GSM cell radius is 35 km. In regions such as vast land, seashore, where with scattered subscribers in low traffic, and the infrastructure facilities such as transmission and power supply are hard to be constructed or unavailable. The radius of cell shall be over 35 km. Huawei extended cell technology breaks the limit of the 35 km and realizes the wide coverage. Supported by BTS hardware, it can cover a range with radius of up to 120 km. It has been implemented successfully in Qindao seashore coverage project since 2004; the maximum coverage distance reached 120 Km. PS：Enhanced downlink throughput in dual-timeslot extension cell

Figure 52 Enhanced downlink throughput in dual-timeslot extension cell

For the PS service, Huawei proposes dual-timeslot extension cell in order to enhance downlink throughput. The cells with coverage over 35 kilometers, such as coast coverage, island coverage, or wide coverage on land, support the PDCH allocation of four downlink timeslots and one uplink timeslot can be performed for the MS with the multi-timeslot capability. The extension cell can provide a data throughput four times of that provided by a traditional cell (single downlink timeslot connection), and thus accelerates the download tasks of the MS, improves the user experience, and helps the operators make more profit out of data services.

AMR&WB AMR

Figure 53 AMR

AMR can select the traffic channel mode (FR or HR) and the coding mode according to the channel quality and load. Therefore, AMR contributes a lot in better speech quality, improved bearer capacity of the system in physical regions and stronger anti-interference capability. It could balance the network quality and capacity, increasing about 40% network capacity. Presently, Huawei BSS technologies support NB-AMR and WB-AMR (both FR and HR). Just through software configuration, operators could realize both AMR FR and AMR HR functions according to the specific network condition. Besides, Huawei BSS technology could dynamically switch AMR FR/HR, leading to up to 40% capacity increase without degradation of service quality. As the system could automatically adjust, the maintenance cost could also be decreased. WB AMR provides clear and loud voice and high-quality speech compared with the narrow band AMR with the sampling rate of 8 kHz and the speech frequency range between 200 Hz and 3400 Hz. In Huawei BSS technology, the AMR wireless link timer is utilized to detect the quality of a wireless link. By setting the wireless link timer of AMR voice service and that of non-AMR voice service separately, the operator could prolong the conversation of AMR voice service,

reduce the call drop rate, and increase benefits and win a high subscribers‟ loyalty. 

Enhanced EDGE Performance When GSM/EDGE radio access network (GERAN) evolution introduced in the network, The rate of PS services in the uplink and downlink is increased greatly. When four timeslots are used for uplink data transmission, the theoretical rate of EGPRS is increased from 230 kbit/s to 300 kbit/s. When ten timeslots are used on the downlink, the theoretical data rate of EGPRS is increased from 592 kbit/s to 984 kbit/s. In order to realize it, Huawei adopts following technologies to enhance the PS service.

Through channel reserved and preemption, it principally assures resources for high-end subscribers or emergency calls. According to priority, this feature can allocate FR channels and good speech quality for high-end users. Introduced HR technology, network capacity can be double without any addition of TRXs.

Huawei is the first vendor in the industry to provide All IP BSS solution. Huawei BSC supports IP over FE/GE, IP over TDM (E1/T1, cPOS). Huawei BSS also can provide all IP interface, including Abis over IP, A over IP, and Gb over IP. Based on ALL IP solution, the TrFO function can be supported to improve the voice quality and TC resources can be saved. Meanwhile, the MSC in pool, the SGSN, in pool can be supported easily. IP transmission offers sufficient bandwidth to the BTS, thus, new services can be developed conveniently and efficiently.

Clock Over IP Support 1588V2

Figure 58 Clock Over IP Application

Clock over IP that complies with IEEE1588V2 provides clock synchronization for several BTSs in the IP network. Compare with the GPS clock, it is a low-cost clock solution. The transmission cost increases because the IP timing packets are sent continuously. The function provided by Huawei, however, allows the operator to define the interval for sending IP timing packets. It can reduce the transmission bandwidth as long as the BTS clock synchronization is guaranteed. 

Ethernet OAM With the introduction of IP GSM, the Ethernet as a type of transport bearer is widely used. As a Layer 2 protocol, Ethernet O&M can report the status of the network at the data link layer. Thus, the network is monitored and managed more effectively. The functions of Ethernet OAM consist of fault detection, notification, verification, and identification. The faults involve the hardware faults that can be detected by the physical layer, such as link failure, and the software faults that cannot be detected by the physical layer, such as memory bridging unit damage. Ethernet O&M plays a significant role in reducing CAPEX/OPEX and complying with the Service Level Agreement (SLA).

5.3.1.6 Network Reliability

MSC Pool



The MSC pool, one BSC can be connected to multiple MSCs simultaneously. With this feature, a maximum of 32 MSCs form a resource pool to provide services for the subscribers under one group of BSCs. In addition, the traffic on the BSC is evenly distributed to the MSCs in the pool according to the NRI or load balancing principle. The MSCs in an MSC pool share the traffic load and resources. Therefore, this feature provides the following benefits: 

MSC pool increases the network capacity and saves the equipment investment.



MSC pool realizes the redundancy backup and thus improves the network reliability because the addition or deletion of an MSC does not affect the services.



MSC pool automatically adjusts the traffic load on an MSC and reduces the operation and maintenance cost of operators.



The MSC pool is logically an MSC. Therefore, the number of handovers between MSCs is reduced and the network performance is improved.

SGSN Pool With SGSN Pool, one BSC can be connected to multiple SGSNs at the same time. This feature, which is similar to the MSC Pool feature, enables a maximum of 32 SGSNs to form a resource pool to provide services for the subscribers belonging to one group of BSCs. In addition, the traffic on the BSC is evenly distributed to the SGSNs in the pool according to the network resource identifier (NRI) or load balancing principle.



Implements redundancy backup and thus improves the network reliability because the addition or deletion of an SGSN does not affect the services.



Reduces handovers between the SGSNs because the SGSNs in an SGSN pool are logically one SGSN and thus improves the network performance.



TC POOL In general, one GTCS belongs to only one BSC and is used to process the CS services of this BSC. The GTCSs in different BSCs are not associated with each other. In this kind of network topology, the TC resources cannot be multiplexed among multiple BSCs. In the scenario where multiple BSCs with small capacity are grouped into a network, the TC resources are greatly wasted. The TC pool adapt to the mode that the GTCS is separated from the BSC cabinet and is connected to the BSC through the Ater interface. The codec resources in the TC pool are shared by the main BSC and sub-BSCs, which work in load sharing mode. In addition, a BSC can be connected to only one TC pool. One TC pool supports a maximum of 16 BSCs. The efficiency of the codec hardware can be increased because multiple BSCs share the same resources in one TC pool. For the small-capacity BSC, 20% to 30% TC codec resources can be saved. Roomage is saved. For example, three small-capacity GTCSs require three cabinets. In TC pool mode, three GTCSs require only one cabinet. In this manner, 40% to 60% area in the equipment room can be saved. The typical network topology is shown in the following figure.

Highlight of Huawei‟s UMTS Solution

5.3.2.1 High Performance HSPA/HSPA+ Solution With self-designed HSPA chipset, high performance HSPA can be achieved in Huawei UTRAN products from day one, supporting full performance HSDPA with 15 codes /14.4 Mbps per user on downlink and HSUPA with 5.76Mbps/user on uplink. For HSPA+ phase1, Huawei supports 21Mbps and 28Mbps per user on downlink with 64QAM and 2x2MIMO technique respectively. In order to save evolution investment and keep the leading position of UMTS, Huawei is recommending HSPA/HSPA+ deployment strategy as follows: 

High performance HSPA/HSPA+ capability To support high performance HSDPA and avoid hardware upgrade at the next stage, the Node B should be ready to support full HSDPA performance from day one. Huawei supports this philosophy by offering a Node B that supports 15 codes and peak bit rates at 14.4Mbit/s per cell. Besides that, Huawei Node B supports all the 12 UE categories, avoiding system upgrade investment along with the UE capability improvement. Huawei HSUPA solution supports E-DCH TTI 10ms and 2ms, peak data rate up to 5.76Mbps. Huawei has helped StarHub Singapore, eMobile Japan, Vodafone Spain, etc. to launch HSUPA commercially with 1.92Mbps since 2007Q3.

With Huawei‟s advanced new generation Node B and RNC, Huawei can also provide high performance HSPA+ phase1 solution, which has the ability to evolution to HSPA+ phase2 smoothly. 

Coverage improvement In HSDPA solution, Huawei supports HS-DPCCH preamble mode technology help the Node B to distinguish between DTX and ACK/NACK without requiring a large ACK transmit power. In this way, the uplink coverage gain is about 0.2dB to 0.9dB with different accompanying DPCH service.

DC-HSDPA Solution improves network performance 1)

Introduction of DC-HSDPA solution HSPA+ data can also be transmitted by the combination of two or more carriers and this result in double or more times of data throughput. HSPA+ based on R8 uses two carriers of consecutive frequencies in downlink and named as Dual Cell HSDPA (DC-HSDPA). If both the network and the user equipment are capable of Dual-Carrier HSDPA operation, the network will be able to configure the user equipment not only with a (primary) serving cell but also with a secondary serving cell originating from the same base station but on an adjacent carrier frequency.

Figure 64 DC-HSDPA working principle

2) Key benefits of DC-HSDPA solution DC-HSDPA is an alternative of MIMO to improve the data throughput and users‟ experience. The carrier aggregation process enables the increase in capacity and user throughput. The key benefits of DC-HSDPA are improved user experience, easy deployment and low network cost.

a)

Improve User Experience & Network Performance

DC-HSDPA provide higher throughput to the end-users even they are far from the transceiver. The coverage performance of a DC user is higher than every other HSPA user. PURCHASING 2G/3G INTERGRATED BTS FOR MOBIFONE NETWORK 2010

(Remark: from Huawei lab test) b)

Easy Deployment and Low Cost

For a deployed network, it is easy to upgrade it for the DC-HSDPA, no new antenna configuration and no new transceivers required for DC-HSDPA. The cells only need software configuration for DC-HSDPA if the network is already operating on the multi frequency configurations in a same coverage area. For the areas where the cell is covered by one carrier frequency only, there will be new requirement for another carrier and it will cost some extra amount.

c)

Decreases burst service and HTTP service relay remarkably

DC-HSDPA has best performance for the burst services like http, gaming or sm all size download files. The burst services consume a small amount of resource and

users‟ transmission time is small, therefore; DC -HSDPA cells can easily share their resources to all the subscribers. d)

Huawei MBMS broadcast solution is the unidirectional transmission of multimedia data (such as text, audio, picture, video) from a single source entity to all users in the broadcast service area, it includes P-T-P (point-to-point) mode and P-T-M (point-to-multi-point) mode. The enhanced

broadcast solution supports “counting/re-counting” function. Based on “Counting/re-counting” result, RNC can select optimum transfer mode: PTM or PTP. In PTM mode, FACH/SCCPCH is used to bear the MBMS services; in PTP mode, DCH or HSDPA is used to bear the MBMS services. If in a cell there is no user interested in one specific MBMS service, RAN can decide to cancel the service automatically. b)

Usually FACH channels in Iub interface are used to transport multimedia broadcast data services from RNC to a few cells in a Node B. Without Iub transmission sharing, each cell must have a FACH channel for transporting the data services from RNC so that more transmission resources must be required in Iub interface. By Huawei innovative Iub transmission sharing solution, a few cells in a Node B can share a FACH channel if all the cells broadcast the same services. We can take 3x1 Node B for an example, 66% transmission resources can be saved if 3 cells share a FACH channel. Obviously operators can benefit from Iub transmission sharing solution. c)

Huawei MBMS solution can support MSCH. Although MSCH is optional in 3GPP, Huawei MBMS solution can support MSCH from day one. With the help of MSCH, MBMS terminal power consumption can be reduced. 

Continuous Efforts in MBMS and Bright Future

For a long time, Huawei has been dedicated in MBMS research in specifications and patents. Up to now, 14 Huawei patents have been stated to ETSI and covered the total patents by 22%. With some leading operators such as Vodafone, Huawei has been making efforts to promote the development of MBMS in the industry. In-depth MBMS research and rich CMB commercialized experiences have helped Huawei to take a leading position in MBMS solution. 5.3.2.3 UTRAN IP Transmission Solution 

Overview As IP technology is implemented more and more widely, IP becomes the most used transport technology with the best cost efficiency. With the development of HSDPA and HSUPA, more transport bandwidth will be needed. UTRAN IP transmission will be a good choice for operators.

Figure 70 UTRAN IP Transport Solution

Based on the current IP network condition, Huawei provides several UTRAN IP transmission solutions. For Iu interface, Huawei provides Ethernet interface. As for Iub interface, Huawei provides ATM access method for traditional ATM network whereas Ethernet interface for IP

network. In order to use popular ADSL port, Huawei also provides ADSL access method. Likewise, to guarantee the quality of voice and to lower cost, Huawei provides hybrid IP transmission. 

IP over ATM Transmission Solution Since ATM transport is the popular transport resource currently, IP over ATM is necessary. When ATM Transport network carries Iub interface data, RNC and NodeB provide E1/T1 interface to access ATM transport network. Huawei Iub interface IP protocol is compliant to 3GPP protocol, UDP carries FP frame, and SCTP carries NBAP data. Huawei provides TCP to carry O&M data. Huawei E1/T1 Iub interface supports ML-PPP/HDLC function in order to provide higher bandwidth. The highlight of IP over ATM: 

Enhance the quality of IP service because ATM can provide the QOS guarantee.



Good ability of flow control and fault resilience, have good network reliability.



Suitable for multi-service, has a good network extension.

Figure 71 IP Transport based on ATM Transport Network 

All IP Transmission Solution In future, IP network will become more popular and will be used for Iub interface. RNC and NodeB can then be connected to each other directly by metro Ethernet network through their FE interfaces to access data communication network. In general, NodeB cannot connect with RNC within the same metro Ethernet. NodeB needs to access to metro Ethernet first, then access to IP network by edge router. However, RNC can access directly to IP network. For NodeB, the last mile access method is abundant, such as ADSL, SHDSL, MSTP, xPON, and so on. To solve the line synchronization for all IP transmission, Huawei provide clock over IP solution instead of GPS to greatly reduce investment.

When the traditional UMTS network introduces HSDPA/HSUPA, The Traffic of RAN will be increased greatly. If adopt traditional TDM transmission, the cost will be too huge to be accepted by Operator. Due to the complexity of access network, If we adopt all IP transmission between Node B and RNC, the QoS of real time service, such as Voice and Video Phone, cannot be assured. In order to reach the balance of QoS and cost, Huawei introduces the IP Hybrid Base Station Transmission Solution, which can solve the QoS of Network with low cost. Huawei proposes the use of hybrid transmission solution on Iub interface whereby voice traffic will be carried by TDM/ATM transport network and best effort traffic carried by IP network.

5.3.2.4 Co-site Solution 

Overview In order to speed up the construction and to cut down the CAPEX for setting up UMTS Network, it is very important to share the existing facilities and the sites as far as practicable. Huawei is experienced at 2G & 3G systems sharing the facilities and sharing the sites. Relying on this experience, Huawei has summarized several general principles for 2G & 3G systems sharing the facilities and the sites. The UMTS network shall be of the excellent performance and 2G network performance has no regression, even adopting 2G & 3G sharing sites solution. Adoption of 2G & 3G sharing site solution shall insure the clear boundary between two Network structures and systems, in order for easy maintenance and system management, and no networks and no services cross-interfering. The key objective for adopting 2G & 3G sharing site solution is to help the service provider customer to cut down the CAPEX for constructing the new network. Any 2G & 3G sharing site solution shall be obeying this economical rule.



Huawei’s Co site solution The co site solution should fully consider the existing site conditions and the requirements of the operator. The aspects of the co site solution shall include the space sharing, antenna system sharing, transmission sharing, power sharing, etc. To ensure the reasonable reutilization of the resource and the safety of the operation, the site survey and the detail site design shall be conducted before the implementation. A general procedure for co site implementation is shown as follows:

Antenna System Sharing Due to the high cost of the installation and maintenance of the antenna system, the antenna system sharing solution is always welcome to the operators. By the development of the antenna technology, the sharing of the antenna and feeder system becomes more and more popular. Huawei could plan and design the antenna syst em sharing solution based on the customer‟s requirements and provide the necessary auxiliary equipments. Some typical antenna sharing scenarios are shown as follows for sample:

Figure 76 Antenna Sharing Solution 

Space Sharing Depending on the space of the existing equipment room or shelter, Huawei will propose the different product solutions accordingly: If there is the enough space in the existing equipment room, Huawei will adopt indoor equipment. During the on site survey and the engineering design period, Huawei will also evaluate the space and the conditions and the life-span of existing shelters and consider the necessary alteration, in order to install the new equipment and make the equipment operating normally.

If there is no enough space in the existing room for installing new equipment, Huawei will propose and adopt the Distributing Base Station (DBS) equipment or outdoor equipment, in accordance with the site conditions. Huawei will evaluate the cost of those two solutions during on site survey and engineering design and select the best solution for customer.

Figure 77 Space Sharing Solution 

Transmission Sharing To some operators, the cost of the transmission renting or maintenance is another huge disbursement, especially for those suburban sites. So the transmission sharing solution is also very important to the operators. Through flexible sharing of the transmission system, the TCO could be obviously saved. Huawei Node Bs support IP RAN and other transmission sharing modes, which will let the operator have abundance choices on transmission sharing. The recommended sharing solution is fractional ATM mode, which could use part of the timeslots of the E1 to carry the ATM message.

5.3.2.5 RAN Sharing Solution 

Overview RAN sharing is an effective way to save CAPEX and OPEX., and approximate 30% ~ 40% CAPEX and OPEX will be saved by RAN sharing. It can quicken the nationwide wide roll-out as well. RAN sharing makes operators focus more on new and innovative services for end users with less effort on roll-out and maintenances. RAN sharing brings better services, better quality of experience and better coverage for end users. Huawei can provide two kinds of RAN Sharing solution: Dedicted Carrier RS (MRNC) and Shared Carrier RS (MOCN). In this proposal, Huawei introduces MOCN solution to SMART.



MOCN In the MOCN solution, operators share resources of the entire UTRAN, including spectrum resources. This solution is applicable to the following scenarios:  

A 3G-licensed operator shares spectrum resources with other operators. The operator who owns multiple spectrums uses these spectrums as a resource pool and shares the pool with the operators who have no spectrums.

MOCN has the following characteristics: 

The UTRAN of the shared area is constructed by one operator and shared by other operators. These operators contribute their spectrum resources (if any) and share all spectrum resources between each other (no matter whether an operator contributes spectrum resources or not).



The shared RAN is connected to the CNs of multiple operators.



Each operator is allowed to deploy Iu Flex, and the CN nodes within an operator's network form a CN pool.



The UEs in the same shared cell are routed from the RAN to the CNs of respective operators. No Iu-Flex Operator A CN node

The MOCN solution enables two to four operators to share RNCs and Node Bs and at the same time to use their own CN. The operators work together to deploy CBS. With the application of this solution, a cell can broadcast a Multiple PLMN ID LIST containing PLMN IDs of multiple operators. The MOCN-enabled Supporting UE can choose a PLMN ID and send it to the RNC. The RNC selects an appropriate route for this UE. If a Non-supporting UE exists in the shared cell, the UE does not report any PLMN information to the RNC. Usually, at this time the RNC can determine a route according to the PLMN ID derived from the IMSI or according to the NRI in the TMSI or P-TMSI. 

If the PLMN ID or NRI corresponds to one of the CNs that the RNC is connected to, the RNC is directly routed to the corresponding CN node.



If the PLMN ID or NRI does not correspond to any of the CNs that the RNC is connected to, the RNC tries to connect to each CN according to a certain principle. If the routing fails, the RNC tries the next CN Node By following the Redirect process until the routing succeeds.

If the IMSI, TMSI, or P-TMSI is unavailable, the RNC keeps trying the CNs one by one according to a certain principle. The MOCN solution uses only one set of OSS equipment. 5.3.2.6 Smooth Evolution to HSPA+/LTE The evolution paths for both distributed Node B and macro Node B is shown as follows:

High Transmission Efficiency /Improved Performance with 2G/3G Integrated

In multi-mode era, transmission cost counted as an important part of operator‟s T CO. Constructing a cost-effective transmission network and being available for the need of the future evolution is a

challenge for all the operators. Huawei‟s co -transmission solution can solve this problem. It includes two solutions based on different bearing network to fully reuse the exiting transmission resource and protect customer investment.

Co-transmission Based on TDM network

Figure 81 Co-transmission Solution Based on TDM network

For some operators, they have an existing SDH network, and want to take back the investment as soon as possible. Moreover, they have a difficulty in newly build an IP bearing network. Therefore, Huawei provides this solution to fully use the existing TDM network. The GSM & UMTS system can transmit the traffic in different TDM time slot independently on the SDH/PDH network through the same E1/T1 line. UMTS BTS can adopt either ATM/IMA/Fractional ATM or IP/ML PPP/PPP solutions. GSM can adopt TDM/ Abis over IP solutions. This makes the application much more flexible.

Figure 82 Co-transmission Solution Based on IP network

For some operators who have an existing IP network or wish to construct an IP transmission

network, Huawei‟s co-transmission solution based on the IP network can fulfill their needs. The GSM & UMTS system can transport the traffic on the same IP network through the same E1/FE/GE line. GSM & UMTS can share the transmission resources dynamically, so there will be a transmission convergent effect, and the transmission efficiency will be enhanced. As a single network, the resources of 2G&3G should be shared in the total system. How to manage the resources to get the efficient and improved network performance? Huawei has done a lot of effort on researching this field, we think it will be a trend of multi-mode network, and our unique Co-RRM and Co- TRM solutions will be benefit and help to achieve customer‟s business plan.

Co-RRM Co-RRM is especially useful for the applications where different RAT cover the same area. Co-RRM maximizes the efficiency of different radio access network by selecting a suitable network for camping or accessing a subscriber. Co-RRM can further lead to reduce power consumption by dynamically allocating traffic between different radio access technologies and shutting down some carriers in a particular RAT. With separate network implementation cell load information is exchanged by core network intervention and it will have the associated signaling delay and also delay in handover procedures, one of the unique advantages with MBSC and Co-RRM feature is that core network intervention is avoided and thus it helps in reducing handover and associated signaling delays as shown in 0, and reduce service interruption time to less than 680 ms.

5.5 Inter-working Solution with Existing GSM/GPRS/EDGE System 5.5.1 Inter-working Solution Overview Spectral efficiency of UMTS is higher than GSM. Hence, operators with high GSM user penetration rate will consider deploying UMTS network to optimize the total capacity of wireless network (GSM plus UMTS) within a certain spectrum. It needs seamless inter-working between existing GSM network and overlay UMTS network to offer continuous services. In different phases of UMTS deployment, the user distribution of GSM and UMTS/GSM dual mode is different and the coverage area of UMTS network increases gradually from the initial phase. It is important to consider different inter-working strategies in order to achieve operating efficiencies and savings. Different concerns for operators in UMTS deployment will result in different inter-working strategies between UMTS and existing GSM network. By considering operating efficiencies, it is a need to maximize network capacity and to initiate as little as possible of inter-RAT handover. If the inter-working solution has very little impact on existing GSM system, the investment on existing GSM network can be reduced, resulting in total cost saving of network deployment. Based on the above considerations, the proposal of an inter-working solution is recommended as compared to different solutions.

5.5.2 Inter-working Solutions and Strategy Camp solution and inter-RAT handover/cell reselection/cell change order solution are two parts of inter-working solution. There is a need to consider these two solutions respectively. Once UMTS is introduced to overlay GSM network, there are three possible solutions for UMTS/GSM dual mode terminal camping. The table below is used to compare these three solutions in terms of impact on network load, service experience for users and handover. To fully utilize the capacity of UMTS network, improve the service quality and attract user

with UMTS based services, Huawei recommends „prefer UMTS‟ so lution for network camp.

Service experience is based on the camping network.

Softer/soft handover can be performed within UMTS network. Inter-RAT handover or cell reselection from UMTS to GSM is performed when there is no UMTS coverage. Hard handover is performed within GSM network. If inter-RAT from GSM to UMTS is performed, it requires big upgrades in GSM network. Handover type is based on the camping network.

Random

based services but can‟t request UMTS specific services like VP unless users do network reselection by hand.

For UMTS CS services, there are four possible solutions for inter-RAT handover between UMTS and GSM. Based on the following analysis, Huawei recommends unidirectional inter-RAT handover for CS service. Unidirectional inter-RAT handover from UMTS: Only inter-RAT handover from GSM to UMTS is performed to offer seamless service. It only needs software patch for GSM system to support inter-handover from UMTS. Bidirectional inter-RAT handover: Inter-RAT handover from/to UMTS to/from GSM is performed to offer seamless service. It requires big changes on GSM BSS and MSC. It means that operators need to increase investments in GSM network to support bidirectional inter-RAT handover. It can‟t make total saving in network deployment and operation. Non inter-RAT handover: In initial phase, scale of UMTS network is small. Calls will be dropped once UEs move out of UMTS area if inter-RAT handover is not performed. In developing/mature phase of UMTS deployment, more and m ore users will camp on UMTS

network. So, the load of GSM will become less. It can‟t maximize the usage of total network capacity if no inter-RAT handover to GSM is performed. Unidirectional inter-RAT handover from GSM: Only inter-RAT handover from UMTS to GSM is performed. It requires big change in existing GSM elements. And it will have call drop once out of UMTS coverage (which will often happens in initial phase of UMTS deployment.). For UMTS PS service, cell reselection/cell change order procedure is used to keep call connection once UEs are moving. It only requires GPRS/EDGE support three additional PURCHASING 2G/3G INTERGRATED BTS FOR MOBIFONE NETWORK 2010

system information: SI 2ter; SI 3; SI 2quater. Therefore, Huawei recommends bidirectional cell reselection/cell change order for PS service.

According to the above analysis, Huawei recommends „prefer to use UMTS, unidirectional handover from UMTS for CS service and bidirectional cell reselection for PS service‟ solution for VMS‟s inter -working between UMTS and existing GSM network. In every different phase of UMTS deployment, the coverage area of UMTS is different. There will be impact from the adopting of handover methods to implement the inter-RAT handover. Considering the small scale UMTS network in initial phase, Huawei recom mends coverage based on inter-RAT handover from UMTS to GSM to keep service continuity. As t he UMTS network develops, load balancing of UMTS and GSM becomes much more critical. Then, Huawei recommends service and load based inter-RAT handover to maximize the total network capacity. The following sub-sections are used to describe the detailed solution of camp and inter-RAT handover/cell reselection.

1)

Camp solution When an UE is switched on or in roaming, its primary work is to find and connect to a network to obtain services. This means that this UE needs to camp on one network. If an UE is switched on in an area covered by UMTS and GSM, Huawei recommends: Network selection to UMTS network: This can be done by parameter setting (HPLMN with access technology) in the USIM card. If different PLMNs are used in GSM and UMTS, UMTS PLMN is set as HPLMN. Else if same PLMN is used for GSM and UMTS, UMTS is set as higher priority access network. Huawei recommends same PLMN for GSM and UMTS for it will not require VMS to sign additional roaming agreement for newly adopted PLMN. Cell reselection to GSM when there is only GSM coverage (out of UMTS coverage) Cell reselection to UMTS when there is UMTS coverage Huawei recommends cell reselection instead of PLMN reselection for UE in idle mode. PLMN reselection will be performed at least 6 minutes after UE comes back to UMTS coverage. During this period, UE cannot request f or UMTS based services. Cell reselection can be performed immediately just based on radio measurement.

Figure 86 Coverage Based Inter-RAT Handover

In the initial phase of UMTS deployment, GSM network has better coverage than UMTS network. Not only that, dual mode users are less than GSM only users. Huawei recommends only coverage based inter-RAT handover is performed. UMTS can support CS service, PS service, combination services (CS + PS). For different services, Huawei recommends different handover strategies: CS services only: Inter-RAT handover to GSM is performed when out of UMTS coverage. Then, the call is kept in GSM until call is ended even UE moves into UMTS covera ge again. PS services only: Inter-RAT Cell reselection (when UE is not in CELL_DCH state) or inter-RAT cell change order (when UE is in CELL_DCH state) to GPRS/EDGE is performed when UE is out of UMTS coverage. When there is UMTS coverage, inter-RAT cell reselection to UMTS is performed to offer higher data services. CS service + PS service: For combined services, Huawei recommends to ensure CS service continuity. The strategy is the same for CS s ervice only. PS service connection will be kept in the same network as CS service connection. UE needs to perform cell reselection procedure to return to UMTS when UE is in idle mode and moved into UMTS coverage. Service based and load based inter-RAT handover; coverage based inter-RAT handover in developing/mature phase.

Figure 87 Service and Load Based Inter-RAT Handover

In developing/mature phase of UMTS deployment, UMTS network has better coverage. Dual mode users are eventually more than GSM only users. Huawei recommends service and load based inter-RAT handover. Considering the capability of GSM network, different handover strategies for different services are requ ired. For details refer to the above figure. K1/ K2% is the load threshold that is used to initialize service and load based handover. They can be set to the same or different value which is less than the threshold used to initialize congestion control. Once cell load exceeds K1/K2%, RNC will initialize corresponding action. R1/R2 data rate is set to a maximum data rate that GSM/GPRS/EDGE can support. As per the specification, this functionality shall be performed under the CN control (CN will set one proper IE in RAB assignment.). Huawei RNC also supports this functionality by RNC configuration. If there are combination services, RNC will first consider handover UE with single connection to GSM and keep UE with combination services in UMTS network because currently only UMTS network can support combination services. When there is no UMTS coverage, coverage based on inter-RAT handover will be performed. The strategy is similar to the one used in initial phase.
