Overview

2.1 Introduction The Dynamic Cell Power Off feature enables a BSC to dynamically power off or power on all the TRXs in a cell that has a co-coverage cell based on traffic load within a specified period. In a multiband network, the 900 MHz cell provides network coverage, whereas whereas the 1800 MHz cell absorbs network traffic. To reduce pow er consumption on a multiband network, the Dynamic Cell Power Off feature is introduced. If the traffic volume is low and the 900 MHz cell can take over all services running on the 1800 MHz cell within a specified period, the 1800 MHz cell can be powered off, thereby reducing BTS power consumption. NOTE l

In a GSM network, if the coverage of cell A includes that of cell B, cell A is a co-coverage cell of cell B. Co-coverage cells are usually planned in multiband networks.

l

To support Dynamic Cell Power Off, a cell and its co-coverage cell must be served by the same BSC.

l

A 900 MHz cell refers to a cell running on the 900 MHz or 850 MHz frequency band, and a 1800 MHz cell refers to a cell running on the 1800 MHz or 1900 MHz frequency band. For details about Network Feature Parameter Parameter Description Description. multiband networks, see Multiband Network

Technical Description

The Dynamic Cell Power Off feature is widely used in dual-band net works whe where the GSM900 and 1800 MHz cells are served by served by the same same BSC. When traffic volume is low, all the TRXs in the 1800 MHz cell are disabled, and the 900 MHz cell provides services for all subscribers in the coverage area of the 1800 MHz cell, thereby reducing the power consumption of the entire network. When traffic volume increases, all the TRXs in the 1800 MHz cell are powered on to meet the traffic requirement in the coverage area. Figure 3-1 shows the overall principles of this feature. Figure 3-1 Overall principles of Dynamic Cell Power Off

3.1 Dynamic Cell Power Off Algorithm The dynamic cell power off algorithm consists of two parts: decision and execution.

3.1.1 Decision When TURNOFFENABLE( BSC6900 , BSC6910 BSC6910 ) is set to ENABLE(Enable) , the BSC determines that a cell can be powered off when all the following conditions are met: l

The current time is within the period specified by the TURNOFFCELLSTRTIME( BSC6900 , BSC6910 BSC6910 ) and TURNOFFCELLSTPTIME( BSC6900 , BSC6910 BSC6910 ) parameters. NOTE l

l

BSC6900 , BSC6910 BSC6910 ) to a value greater than the You can set TURNOFFCELLSTRTIME( BSC6900 , BSC6910 BSC6910 ). In this case, the period when the value of TURNOFFCELLSTPTIME( cell can be powered off spans more than on e day. For ex e xample, if you you set TURNOFFCELLSTRTIME( BSC6900 , BSC6910 BSC6910 ) to 23:00 and TURNOFFCELLSTPTIME( BSC6900 , BSC6910 BSC6910 ) to 06:00, the specified period starts from 23:00 till 6:00 on the next day. BSC6900 , BSC6910 BSC6910 ) equals the value of If the value of TURNOFFCELLSTRTIME( TURNOFFCELLSTPTIM E( BSC6900 , BSC6910 BSC6910 ), a cell can be powered off during any period of the the day. day.

The current date is outside the specified period during which the intelligent shutdown of TRX power amplifiers (PAs) (PAs) is prohibited. NOTE

l

l

The period when the intelligent shutdown of TRX PAs is prohibited is determined by the StartMonthDSTPA( StartMonthDSTPA( BSC6900 , BSC6910 BSC6910 ), StartDayDSTPA( StartDayDSTPA( BSC6900 , BSC6910 BSC6910 ), EndMonthDSTPA( EndMonthDSTPA( BSC6900 , BSC6910 BSC6910 ), and EndDayDSTPA( EndDayDSTPA( BSC6900 , BSC6910 BSC6910 ) parameters. parameters.

l

During the period when the intellige nt shutdown shutdown of TRX PAs TRX PAs is prohibited, the TRXs in the cell cannot be disabled, and therefore the cell cannot be powered off. For example, if the specified period when the intelligent shutdown of TRX PAs is prohibited is "October 1" and the specified period when the cell can be powered off is "23:00 till 06:00", the cell cannot be powered off from 23:00 23:00 on September September 30 until until 06:00 on on October 2. 2.

The duration from the current time to the time specified by TURNOFFCELLSTPTIME( BSC6900 , BSC6910 BSC6910 ) is longer than the period specified by PROTECTTIME( PROTECTTIME( BSC6900 , BSC6910 BSC6910 ).

l

The duration from the last time the cell was powered on to the t he current current time is longer is longer than PROTECTTIME( BSC6900 , BSC6910 BSC6910 ). the period specified by PROTECTTIME(

l

The number of activated TCHs and PDCHs in the cell is is less than than the value of TURNOFFCELLCHANNUM( BSC6900 , BSC6910 BSC6910 ) .

l

The measured load of the co-coverage cell is lower tha n the thr eshold eshold s pecified by SAMECVGCELLLOADTHR SAMECVGCELLLOADTHRD( D( BSC6900 , BSC6910 BSC6910 ) for N consecutive times, where N SAMECVGCELLLOADSTA TATTM( TTM( BSC6900 , BSC6910 BSC6910 ). is specified by SAMECVGCELLLOADS Here, cell load is expressed by the percentage percenta ge of occu pied channels channels in a cell. When calculating the load of a co-coverage cell, the t he BSC determines determines whether to include the number of dynamic PDCHs in the number of occupied or i dle TCHs based on the value BSC6910 ). of TurnOffLoadType( BSC6900 , BSC6910 NOTE

3.1.2 Execution of Dynamic Cell Power Off When the BSC determines that a cell can be powered off: l

If the cell does not have an established call or a call that is being established, the BSC immediately powers off the cell.

l

If the cell has an established call or a call that is being established, the BSC performs one of the following operations to release an occupied channel, depending on the channel type: –

TCH: The BSC attempts to hand over the call that occupies the TCH to a neighboring cell. NOTE

PreferTurnOffBCCHTRXSw TRXSw is set to ON(On) and the cell has at In this scenario, when PreferTurnOffBCCH least two TRXs: l

If the BCCH TRX is idle, the BSC preferentially turns it off, regardless of whether other TRXs are occupied. When the BCCH TRX is turned off, the BCCH power amplifier is also turned off, preventing the access of any new calls. This mechanism prevents the RR370: Congestion Rate on SDCCH per CELL (due to Busy) counter from increasing due to a large number of location update failures (because the BSC does not allocate channels in a cell when the cell is being powered off). The BSC turns off other TRXs when they become idle.

l

If the BCCH TRX is not idle, the BSC performs an inter-cell or intra-cell handover on the call occupying the TRX. The BSC then preferentially turns off the BCCH TRX once it becomes idle. When the BCCH TRX is turned off, the BCCH power amplifier is shut down. This mechanism prevents the SDCCH congestion rate from increasing due to no channel allocated to a new call during the cell power off. The BSC turns off other TRXs when they become idle.

–

SDCCH: SDCCH: The BSC waits until the call releases the occupied SDCCH.

–

PDCH: The BSC releases the occupied PDCH.

After releasing all occupied channels, the BSC powers off the cell. Figure 3-2 shows the procedure. Figure 3-2 Procedure of executing dynamic cell power off

1.

The BSC BSC sends sends the BTS BTS a Set Set Trx Trx Pa message, message, in which the value value of of "operatio "operationalT nalType" ype" in the "bsc-bts-set-trx-power" "bsc-bts-set-trx-power" information element (IE) is "power-off". "power-off".

2.

Upon recei receiving ving the the Set Set Trx Trx Pa message, message, the the BTS starts starts to disable disable the TRXs TRXs in the the cell cell and responds to the BSC with a Set Trx Pa Ack message.

some services on the non-BCCH TRX have not been handed over to another cell, the TRX query result indicates that the TRX has been in power-off status. The BTS will proactively power off off the power amplifier amplifier after services services are released. Upon powering off the cell, the BSC stops sending system information (SI) and paging messages in the cell and prohibits any calls (for example, a call handed over from another cell) from accessing the cell.

3.2 Dynamic Cell Power On Algorithm When the traffic volume in the area served by the co-coverage cell increases, the powered off cell needs to be powered on to carry some traffic. The dynamic cell power on algorithm consists of two parts: decision and execution.

3.2.1 Decision OFFENAB LE( BSC6900 , BSC6910 BSC6910 ) is set to ENABLE(Enable) , the BSC When TURN OFFENAB determines that a powered off cell can be powered on when either of the following conditions is met: l

l

The current time is outside the period specified by the TURNOFFCELLSTRTIME( BSC6900 , BSC6910 BSC6910 ) and TURNOFFCELLSTPTIME( BSC6900 , BSC6910 BSC6910 ) parameters. The measured load of the co-coverage cell of the cell is higher than or equal to the BSC6910 ) and the threshold specified by TURNONCELLLOADTHRD( BSC6900 , BSC6910 duration from the last time the cell was powered off to the current time is longer than the PROTECTTIME( BSC6900 , BSC6910 BSC6910 ). period specified by PROTECTTIME( Here, cell load is expressed by the p ercentage of occupied occupied channels in a cell. When calculating the load of a co-coverage cell, the BSC determines whether to include the number of dynamic PDCHs in the number of occupied or i dle TCHs based on the value BSC6910 ). of TurnOffLoadType( BSC6900 , BSC6910 NOTE

The BSC measures the load of the co-coverage cell every minute.

3.2.2 Execution When the BSC determines that a powered off cell ce ll can be powered powered on, on, the BSC immediately powers on the cell. The procedure of executing dynamic cell power on is similar to that of executing dynamic cell power off, except except that the messages messages carry different different values. Figure 3-3 shows the procedure.

TRX Power Amplifier Intelligent Shutdown

It is recommended that the Dynamic Cell Power Off feature be used with the TRX Power Amplifier Intelligent Shutdown feature, and the specified time when TRX Power Amplifier Intelligent Shutdown starts be earlier than the specified time when Dynamic Cell Power Off starts. This provides the following benefits: l

When traffic volume in the cell decreases, TRX Power Amplifier Intelligent Shutdown enables the BSC to disable idle TRXs in the cell, thereby reducing cell load.

l

When cell load is reduced to a certain level, Dynamic Cell Power Off enables the BSC to disable the BCCH TRX, thereby decreasing BTS power consumption.

NOTE If TRX Power Amplifier Intelligent Shutdown is enabled alone in a cell, the BSC can disable all the TRXs except the BCCH TRX in the cell, and the cell can continue providing services for subscribers. However, if Dynamic Cell Power Off is enabled alone in a cell, the BSC disables all the TRXs in the cell when related conditions are met. In such a case, the cell will no longer provide services for subscribers.

Network Impact

5.1 System Capacity System capacity decreases after a cell is powered off.

5.2 Network Performance When the BSC dynamically powers off a cell, the SDCCH congestion rate will slightly increase. When the BSC dynamically powers off a cell, the occupied PDCHs are released and ongoing packet switched (PS) (PS) services are interrupted. The PS services will continue after the MSs reselect to neighboring cells.

6.4.4 Activation Observation NOTE l

Ensure that the following conditions are met before verifying this feature: The cell to be verified has a co-coverage cell that works correctly. There are no call access requests in the cell to be verified. The traffic of the co-coverage cell is lower than the threshold specified by Same Coverage Cell Load Threshold.

l

l

Set Same Coverage Cell Load Threshold to a value close to the maximum value 100 in step 2. In this way, the BSC can easily determine that the current cell can be powered off. After the verification, set this parameter to an appropriate value based on the network plan. The time to wait before you run the DSP GCELLSTAT command in step 3 depends on the value of the Same Coverage Cell Load Stat. Time parameter (default value: 5). If the value of this parameter is n, n, wait n minutes minutes and then run the DSP GCELLSTAT command.

On the BSC LMT, LMT, perform the following steps:

Step 1 Start an Abis Interface CS Trace task to trace messages over the operation and maintenance link (OML).

Step 2 Run the SET GCELLDYNTURNOFF command with its parameters set as follows: Issue 01 (2017-03-15)
