Power Budget Averaging Period HO AVPER The number of the most recent downlink power level measurement values concerning the serving cell and the neighbouring cells, which are used in the power budget averaging procedure for handover. The averaged measurement values are normally given every SACCH block period by the averaging procedure. The bigger the window size (number of measurements) is, the more precise the values of the averaged parameters are. When the values are not precise enough, the probability of an incorrect handover decision will increase. However, a too big window size can cause a delayed handover decision, and so dragging the call. It could cause bad quality and a higher interference probability due to the an unnecessary increased transmit power of the currently serving base station.

Signal Quality: Averaging Period HO HOCSQ-c The number of the most recent quality measurement values, which are used in the quality averaging procedure for handover. A_QUAL_HO is used for the uplink and downlink by the BSC. The averaged measurement value is normally given every SACCH block period by the averaging procedure. The averaged measurement value is compared with the corresponding thresholds for handover decisions. The recommended default value applies for disabled DTX. With DTX enabled the weighting factor for Full measurements is considered and should be set to 2. To get a effective window size of 4 the recommended default value for this attribute with DTX enabled is 8.

AC_CN




no class barred 0-15 0-9: normal subscriber, 10: emergency calls, 11-15: special or restricted LO/UL Access Control Class N is used to bar MSs of specific access classes. BTS ACCESSCLASS

Not Allowed Access Classes CELL ACC The Parameter AC_CN is used to prevent MSs belonging to special access classes from making access attempts (including emergency call attempts) or responding to paging messages in the specified area. The use of this facility allows the network operator to prevent overload of the cell under critical conditions. It is not intended that access control be used under normal operating conditions. The integers specified define the classes inaccessible to the MS. The access classes the MS is allowed to use are stored on its Subscriber Identity Module (SIM). If the access for a certain class is barred, this is no reason for an MS for cell reselection, i.e. the MS can not access the network. If there is an overload on the RACH, it should be tried prior of barring an access class to reduce the number of access attempts by decreasing parameter 'MAX_RETRANS'.

True Boolean False: disable feature, True: enable feature LO/UL This parameter indicates whether the MS is allowed to apply the IMSI attach and detach procedures. BTS WIMSIATTDET

Allow IMSI Attach Detach BTS CONFCCH-c Specifies whether the VLR in the network supports IMSI attaching and detaching. If enabled, each MS that is switched off transmits the 'IMSI detach' message to the network before powering down. When it is switched on again, it will send the 'IMSI attach' message. If the VLR entry of the MS specifies that the MS is currently detached, no paging to this MS will take place. Instead, any call termination attempt to the detached MS can be directly routed to congestion tone, or an announcement by the network. If there is an overload on the paging channel, ATT may be a means to reduce the overload. bts allowIMSIAttachDetach

Up to all six of the access classes 10-15 may be mentioned. BTS BARSEQ10_15

Access Class Overload Control: Classes 10 to 15: Bar Sequence CELL OVERLOAD-f Barring is used to prevent MSs belonging to special access classes from making access attempts (including emergency call attempts) or responding to paging messages in the specified area. The use of this facility allows to recover from overload. The MS stores the access control class on its Subscriber Identity Module (SIM). If the access for a certain class is barred, MSs with that class may only try to get a connection in the neighbour cells. Automatic barring is done by the BSS in case of overload. Depending on the severity of overload the BSS starts with barring access classes 0-9 with random starting class and step size M1 (unbarring with step size M2). If classes 0-9 are barred and there is still an overload situation, the BSS continues barring with access classes 10-15. The barring sequence for access classes 10-15 is given in parameter 'Barring Sequence' and the step size in N1 (unbar: N2). The timer T17 (MAP-Timer) and T18 (MAPTimer) are used for barring resp. unbarring. Automatic barring can be enabled/disabled with flag EN_ACC_BARRING. See also: EN_ACC_BARRING, M1, M2, N1, N2, T17 (MAP-Timer), T18 (MAP-Timer) The operator can bar manually special MS access classes with parameter AC_CN. -

BS Identity Code: BCC CELL BSIC-b The Base Station Identity Code (BSIC) consists of the Network Colour Code (NCC) and the Base Station Colour Code (BCC). The BSIC is a local colour code that allows a MS to distinguish between different neighbouring base stations. The BSIC is broadcast on the synchronisation channel SCH. The MS uses the BSIC in the following way: 1. In idle mode the MS shall attempt to check the BSIC for each of the 6 strongest non-serving cell BCCH carriers at least every 30 seconds, to confirm that it is monitoring the same cell. If a change of BSIC is detected then the carrier shall be treated as a new carrier and the BCCH data redetermined. 2. In connected mode the MS shall demodulate the SCH on the BCCH carrier of each surrounding cell and decode the BSIC as often as possible, and as a minimum at least once every 10 seconds. For broadcast (BCCH) and common control channels (PCH and AGCH) the BCC is used as TSC, i.e. the TSC set by operator is ignored.

No. of Blocks For Access Grant BTS CONFCCH-a The Paging Channel (PCH) and the Access Grant Channel (AGCH) share the same TDMA frame mapping when combined onto a basic physical channel. The channels are shared on a block by block basis, and information within each block allows a mobile to determine whether the block contains paging messages or access grants. Every PCH can be used by the system as AGCH, but it is not allowed to the system to use AGCH-blocks to transmit paging requests. However, to ensure a mobile satisfactory access to the system, a variable number of the available blocks in each 51-multiframe can be reserved for access grants only. BS_AG_BLKS_RES gives the number of blocks reserved and is broadcast on the BCCH. It is useful, to set this parameter to the smallest value and let the system organise the channel usage. In the case of Mobile Originated Calls more AGCHs will be needed, in the case of Mobile Terminated Calls the necessity for PCHs increases. In the average, the number of Mobile Originated Calls is very much higher than the number of Mobile Terminated Calls. If this parameter is chosen too high with the result of a PCH-shortage in the case of high traffic density, there may arise an overload-indication of the PCH. See also CH_TYPE Range depends on CH_TYPE of BCCH channel: - 0-7: if BCCH channel is of type mainBCCH - 0-2: if BCCH channel is of type mainBCCHCombined - 1-2: if BCCH channel is of type mainBCCHCombinedCB If CellBroadcast is enabled for a cell, BS_AG_BLKS_RES must not be set to 0. bts noOfBlocksForAccessGrant

No. Of Multiframes Between Paging BTS CONFCCH-b When BS_PA_MFRMS is increased , the number of paging groups is increased too with the advantage that idle subscribers have to be less active. BS_PA_MFRMS should be chosen in an appropriate way. If the value is too small, there may be an overload due to a shortage of paging channels. If the value is too high so that the time between two paging calls is high, it may occur an overload situation in the paging queue in the BSS. The available paging blocks per CCCH is determined by the BCCH channel type (9 in case of mainBCCH, 3 in case of mainBCCHCombined) reduced by BS_AG_BLKS_RES (number of blocks reserved for access grant) and this multiplied with BS_PA_MFRMS + 2.

BTS Position, Predecessor Cell This parameter allows the BSC to determine how the different BTS are concatenated in a multidrop chain. In case of an Abis link break the BSC calculates, which BTSs are affected. If the attribute is set to 'No predecessor cell', then the BTS is the first BTS in the chain. If different objects BTS have the same 'predecessor cell', then they form a multicell site (not in case of RBS900). At the GUI the attribute 'BTS Position' can be set to one of the values "Predecessor Cell", "Connected to BSC" or "Prodecessor Unknown". If "Predecessor Cell" is selected the attribute 'Predessor Cell' has to be set to the distinguished name of the predecessor BTS. At the AUI the attribute 'PRDBTSUNDEF' defines whether the BTS position is known (value 'false') or not known (value 'true'). If the position is known the attribute 'PRDBTS' has to be set to an empty string if the BTS is connected directly to the BSC, or set to the distinguished name of the predecessor BTS if the BTS is connected to another BTS. -

Cell Barred CELL CBAR A MS can only camp on those cells, which are not barred. In case of emergency calls, the access to the net is allowed. Handover into a barred cell is possible. This parameter is used to configure "handover-only" cells (i.e. this parameter does not effect a mobile's behaviour in dedicated mode). It should be taken care, that not too many cells of a network are barred at the same time to avoid overload in unbarred neighbour cells and to allow subscribers to find another cell, where calls are allowed. For cell selection according to the C2 criteria for GSM phase 2 MS see also CELL_BAR_QUALIFY.

If CELL_RESELECT_PARAM_IND is disabled the C1 criterion will be applied. The C2 reselection criteria was introduced to support hierarchical cell structures to encourage mobiles to 'camp-on' different cell layers in accordance with its speed by using static and dynamic offsets. A MS should reselect a cell layer that corresponds to its speed, i.e. a MS, that is moving very slowly or not moving at all, should reselect a lower layer cell, and a fast moving MS should reselect a upper layer cell. C2 is calculated for all cells in a mobile's strongest server list that exhibit a positive C1 value. If C1 < 0, C2 is not calculated for that cell.

Cell Global Identity: Cell Identification NCELL CDESC-a Uniquely identifies a neighbour cell within the LocationArea. The Cell Global Identity (CGI) consisting of LAI and CI uniquely identifies a cell within the whole world. The Location Area Identification (LAI) consists of the concatenation of MCC, MNC and LAC. For every radio cell in a GSM PLMN, a number of up to 32 neighbouring cells can be specified to be monitored by every MS with a call in progress. The MS takes signal strength measurements on the BCCH carriers of these neighbour cells and reports them to the BSS. In the BSC, the measurement result reports of every MS are evaluated and form the basis for handover decisions. In order to identify the neighbour cells, the MS decodes the Base Station Identity Code (BSIC) of every monitored neighbour cell and includes this information together with information on the respective BCCH carrier frequency in the measurement result reports. In handover required messages sent from the BSC to the MSC, the preferred target cells for handover are identified by LAC (DMCS) resp. LAI (Ericsson) and CI. Therefore, in the BSC, the cell identification information provided by the MS has to be mapped onto the LAC/LAI and CI used to identify radio cells in the PLMN. See also MCC_NC(n), MNC_NC(n), LAC_NC(n) CI_NC(n) shall have the same value as parameter CI of that neighbour cell. adjacentCellHandOverGSM0508 cellGlobalIdentity.CellIdentity

EN_ACC_BARRING




True Boolean False: disable feature, True: enable feature LO/UL Enables automatic access class BARRING in case of overload. BTS ACCCLASSBAR

Access Class Overload Control: Barring Enabled CELL OVERLOAD-a Barring is used to prevent MSs belonging to special access classes from making access attempts (including emergency call attempts) or responding to paging messages in the specified area. The use of this facility allows to recover from overload. The MS stores the access control class on its Subscriber Identity Module (SIM). If the access for a certain class is barred, MSs with that class may only try to get a connection in the neighbour cells. Automatic barring is done by the BSS in case of overload. Depending on the severity of overload the BSS starts with barring access classes 0-9 with random starting class and step size M1 (unbarring with step size M2). If classes 0-9 are barred and there is still an overload situation, the BSS continues barring with access classes 10-15. The barring sequence is given in parameter 'Barring Sequence' and the step size in N1 (unbar: N2). The timer T17 (MAP-Timer) and T18 (MAP-Timer) are used for barring resp. unbarring. Access class barring can only be enabled if it is enabled in the local configuration area, too. See also: Barring Sequence, M1, M2, N1, N2, T17 (MAP-Timer), T18 (MAP-Timer) The operator can bar manually special MS access classes with parameter AC_CN. -

EN_BSS_HO




True Boolean False: disable feature, True: enable feature LO/UL Enables the BSS to perform intercell handover. When it is disabled, the MSC will decide and perform handover. HOCTRL INTERDEC

Enable Handover: Intercell Decision HO ENICDEC Intercell handover for TCH and SDCCH may be performed by the MSC (MSC-controlled / external) or autonomously by the BSC (BSC-controlled / internal). The O&M flag EN_BSS_HO is used to enable or disable BSCinternal intercell handover for handover requests originating in a specific cell of a BSS. This flag is independent of the flag EN_INTER_HO which enables or disables the generation of requests for intercell handover in the individual cells of a BSS. However, the flag EN_BSS_HO is only meaningful if intercell handover is enabled. Disabling BSS-controlled intercell handover gives the MSC the full decision authority on handover requests and increases the handover processing load in the MSC.

True Boolean False: disable feature, True: enable feature LO/UL Enable CCCH (RACH and PCH) LOAD Indication recognition procedures BTS LOADIND

Load Indication Enabled BTS ENLDIND This parameter is used to enable/disable the periodic sending of Common Control Channel Load Indication messages from the BTS to the BSC for a specific cell. If enabled, CCCH LOAD Indication messages containing information on the current load situation on the random access channels (RACH) and the paging channels (PCH) of the concerned cell are periodically sent from the BTS to the BSC. The sending rate is determined by the O&M parameter CCCH_LOAD_IND_PERIOD. In the case of multiple CCCH, independent CCCH LOAD Indication messages are sent for each CCCH subchannel. In the BSC, the CCCH LOAD Indication messages are evaluated in order to detect overload situations and to initiate appropriate countermeasures. Disabling CCH LOAD Indication may be useful in some critical situations to prevent Abis interface from signalling overload or the BSC from processor overload. Normally, however, CCCH LOAD indication should be enabled to allow RACH and PCH overload detection and appropriate countermeasures in the BSC or OMC. See also CCCH Load Ind.

It affects intercell handover from TCH to TCH as well as intercell handover from SDCCH to SDCCH and SDCCH to TCH. Temporarily disabling incoming handovers may be useful in case of maintenance at that cell.

EN_INTER_HO




True Boolean False: disable feature, True: enable feature LO/UL Enable intercell handover HOCTRL INTERHO

Enable Handover: Internal Inter-Cell HO ENBSSHOC-a The flag EN_INTER_HO enables or disables the handover comparison process for outgoing intercell handover in the individual cells of a BSS. It affects intercell handover from TCH to TCH as well as intercell handover from SDCCH to SDCCH. If intercell handover is disabled, requests for intercell handover (BSC-controlled or MSC-controlled) originating in the concerned cell are inhibited, regardless of the current radio link measurements of the calls in progress. Temporarily disabling outgoing handovers from a specific cell may be useful during updates of handover control parameters or to prevent neighbouring cells or network elements (BSC, MSC) from handover accesses or handover load, respectively. If intercell handover is enabled, requests for intercell handover originating in the concerned cell initiate a BSC controlled (internal) or MSC-controlled (external) intercell handover. This function is independent of the flag EN_BSS_HO which enables or disables the BSS-internal execution of intercell handover and of EN_INTRA_HO which enables or disables intracell handover.

EN_INTRA_HO



66

True Boolean False: disable feature, True: enable feature LO/UL Enable intracell handover HOCTRL INTRAHO

Enable Handover: Internal Intra-Cell HO ENBSSHOC-d Specifies whether handovers within the cell are enabled or not. An intracell handover is used to switch a call from one TCH (traffic channel) or SDCCH to another within the same cell (either on the same or on different frequencies). The reason to do so is the receive quality. Preferable another frequency or at least a distant time slot on the same frequency should be selected. If intracell handover is disabled, requests for intracell handover due to interference are inhibited. Note that an inhibited request for intracell handover is not automatically substituted by a request for intercell handover. This function is independent of all intercell handover O&M parameters (e.g. EN_INTER_HO). Intracell handover is disabled if frequency hopping (FH) is activated and for a time period of A_LEV_HO after channel allocation.

EN_MS_PC



68

True Boolean False: disable feature, True: enable feature LO/UL Enable dynamic power control for all MSs in a cell (uplink). POWER PWRCTRLMS

Enable MS RF Power Control PC ENMSPC Specifies whether dynamic uplink power control is enabled or not. If True, the MS adopts power according to the power control commands from the BSC. This will save the MS battery. The main reason for power control is, however, improving the spectral efficiency within the network (cell). Reducing power on BTS or MS, whilst keeping similar communication quality, decreases interference caused on other calls in the surrounding area. If this parameter is False, the MS will always transmit at maximum power level, that is calculated by the BSC as the minimum level of the MS power class and MS_TXPWR_MAX. Disabling MS power control may be useful for test purposes but is inappropriate during regular network operation since cellular network planning (frequency reuse) is based on the assumption of dynamic RF power control on the uplink.

EN_PBGT_HO




True Boolean False: disable feature, True: enable feature LO/UL Enable handover due to power budget (PBGT) HOCTRL PWRBGHO

Enable Handover: Optional Power Budget HO ENBSSHOC-b This parameter is used to enable or disable intercell handover due to power budget criteria in a specific cell. Of all handovers, this handover is the most common. A power budget handover takes place as soon as a better cell with respect to the power budget is available to handle the call. A power budget handover is based on the path loss on the downlink. The assumption is made that the path loss is equivalent in both directions. The path loss is the difference between the actual transmit power of the BTS and the signal level received by the MS. Generally, the MS will switch to the BTS with the lowest path loss. If power budget handover is disabled the power budget criterion is still evaluated in the BSC to compile the list of preferred target cells for handover requests with other causes. If power budget handover is enabled and intercell handover is enabled (EN_INTER_HO), requests for intercell handover with cause 'better cell' (power budget) may be generated and initiate an intercell handover under control of the BSC or MSC.

True Boolean False: disable feature, True: enable feature LO/UL Enable/disable flag for sending of RF Resource Indication from BTS/TRX to BSC. HOCTRL IDLECHNSUPV

Enable Idle Channel Supervision The idle channel supervision is used for the interference quality of channels, which are candidates for channel allocation, intracell and intercell handover. The philosophy is to direct every MS onto an idle channel with an interference level as low as possible. This is applied for TCHs. For the allocation of SDCCHs of a BTS the consideration of interference bands is not required. The EN_RF_RES_IND flag enables/disables the measurement of interference levels on idle TCHs in the BTS/TRX, the sending of the results as RF resource indication messages from the BTS/TRX to the BSC, and channel allocation regarding interference level in the BSC.

If power control is not done because of the cell type or not helpful anymore, the BS normally starts the intercell handover procedure. This parameter is used to enable or disable intercell handover due to RXLEV criterion (received signal strength) in a specific cell. If RXLEV handover is enabled and intercell handover is enabled (EN_INTER_HO), requests for intercell handover with cause 'RXLEV' may be generated and initiate an intercell handover under control of the BSC or MSC.

EN_SDCCH_HO




True Boolean False: disable feature, True: enable feature LO/UL Enable SDCCH - SDCCH handover HOCTRL SDCCHHO

Enable Handover: SDCCH HO ENBSSHOS-c Specifies whether SDCCH intercell and intracell handovers are enabled or not. Usually, handovers take place on the TCH, when the call is in the speech stage. However, in rare cases it may be necessary to perform a handover when, e.g. the call is still in establishment phase. In that case the SDCCH will be handed over to another frequency or time slot. This type of handover is more likely to take place during the transmission of short messages (SMS). This parameter is only meaningful if either intracell handover (EN_INTRA_HO) or intercell handover (EN_INTER_HO) or both of them are enabled. MSC 5ESS GSM8.0 is not supporting the feature. MSC has also to support SDCCH - SDCCH HO. If not, only BSC controlled HO of this type will be possible. -

Error Id BTC DIP-d The digital input point parameters contain information required by the BTC to assign individual configuration data to each input line on the Control Alarm and Control Port (CAP/CCP) for the RBS900 or the external alarm box (EAB) for the BTS2000. Depending on the BTS type up to 24 external devices can be connected to the BTC (see table below), but only 16 are visible on the OMC. This parameter defines the error id of the alarm message, which is generated if the physical input potential changes to high or low (defined by the parameter 'Alarm State (n)'). The ranges of the external error ids are predefined in the BTS and are different for each BTS type: RBS900 - indoor: 512-527 (16) RBS900/4 - outdoor: 528-543 (16) BTS2000/2C - outdoor: 8704-8711 (8) BTS2000 - outdoor: 8704-8711 (8) BTS2000 - indoor: 8704-8727 (24) For the BTS2000 family the external error ids are defined fix for each input line and cannot be changed from the OMC. The BSC does not forward the values defined on the OMC to the BTS2000. The external error ids on the OMC are only used as a reference for the OMC parameter 'external alarm string'. The connection of physical devices to the input points is also fix. The RBS900 uses the external error ids and an exact range check is performed. For the RBS900 the operator can assign for different BTSes different error ids to the same input line. For the RBS900 indoor even different physical devices can be connected to the input lines. For the RBS900 outdoor this connection is fix. See also Input Point Adr (n), Input Hysterese (n), Alarm State (n) -

FHE Slice Address RT FHESLICE-a The Frequency Hopping Equipment (FHE) is used in the RBS900 for baseband hopping. The RTs are split in a digital and a transceiver part that are connected by the FHE switch. The transceiver part has a fix connection to the FHE. The digital part is connected with wires. The operator must set this parameter for each RT to indicate which FHE slice the RT is wired to. This parameter reflects the physical hardware of the RBS900. Therefore it is not supported by the other BTS types. Value must be unique among RTs within the same BTS. -

The value specifies the cable length from the slave BTS to the master BTS.

HO_MARGIN(0,n)


Dependency:



5dB = 29 0-48 0 = -24dB, 1 = -23dB, ..., 48 = +24dB LO/UL This parameter defines the margins for power budget handover from the current cell to the neighbouring cells. ADJCELL HOMGRN

Handover Margin NCELL CDESC-j Range:(-24) - 24 dB A basic radio criterion for handover decisions in the BSC is the power budget (PBGT) criterion. The power budget is a relative measure of the MS link power budget on a potential new link to a neighbouring cell with respect to the current link in the serving cell. Basically, the MS should always communicate with or be handed over to the cell or BTS with the lowest possible link power budget. Evaluating the power budget criterion involves the parameter HO_MARGIN(0,n) for every neighbouring cell which is subtracted from the respective PBGT(n) results, thus, producing a 'handover margin'. By proper choice of the parameters HO_MARGIN(0,n) in adjacent cells, it is possible to shift cell boundaries and to achieve a handover hysteresis which prevents repetitive handovers between adjacent cells. If the list of neighbouring cells is being altered, it should be ensured that handover processing is only active if all lists of neighbouring cell evaluation parameters are properly installed by O&M, i.e. the individual lists have the right relation to each other. If necessary, the handover processing may be suspended during a change until this is guaranteed. Higher values: fewer handovers will be triggered but the size of the cell will be bigger and so the spectral efficiency will decrease. Lower values: more handovers will be triggered which will cause more signaling traffic and can lead to ping pong situations. This parameter is unique for the relation between a cell and a neighbour cell. See also EN_PBGT_HO, A_PBGT_HO If HO_MARGIN(A,B) is the margin for a handover from cell A to the adjacent cell B (specified in cell A) and vice versa, then the dB values should adhere to: HO_MARGIN(A,B) + HO_MARGIN(B,A) > 0dB adjacentCellHandOverGSM0508 hoMargin

Synthesiser hopping: Each RT is able to hop over a number of frequencies independent of the existance of other RTs. The RBS900 is only able to support baseband hopping. For the other BTS types the hopping mode can be modified locally with the RBT depending on the hardware capabilities. -

HSN




0 (cyclic) 0-63 0 = Cyclic hopping, 1-63 = Random hopping LO The Hopping Sequence Number is used to derive the order in which the allocated frequencies are used. FH HOPSEQNO

Hopping Sequence Number FHS HSNR HSN is a constant parameter in the frequency generator equation used in the frequency hopping algorithm. In case of HSN=0 a cyclic hopping sequence of the frequencies defined by the mobile allocation (MA, see also MA_ARFCN) is generated. In all other cases a quasi random sequence is generated which is well calculable by linked BTS and MS. The feature of random frequency hopping is the statistical distribution of cochannel interference and adjacent channel interference by choosing different values for HSN in cochannel cells (same frequency in next cell clusters) and adjacent cells (different frequencies in same cluster). From the viewpoint of cellular network planning it is useful to test the individual interference relation between two cells by using a cyclic hopping sequence HSN=0. This would be applicable in systems with a great number of allocated frequencies or in synchronised systems. Physical channels on the same timeslot with equal MA and HSN are discriminated by the index offset MAIO, which is calculated by the BSS. Due to an MS procedure for measurement reporting with DTX enabled, the use of cyclic hopping where N mod 13 = 0 should be avoided (N being the number of frequencies in the MA). frequencyHoppingSystem hoppingSequenceNumber

The LAC identifies a location area within the PLMN. It consists of one or more cells identified by CI. For every radio cell in a GSM PLMN, a number of up to 32 neighbouring cells have to be specified to be monitored by every MS with a call in progress. The MS takes signal strength measurements on the BCCH carriers of these neighbour cells and reports them to the BSS. In the BSC, the measurement result reports of every MS are evaluated and form the basis for handover decisions. In order to identify the neighbour cells, the MS decodes the Base Station Identity Code (BSIC) of every monitored neighbour cell and includes this information together with information on the respective BCCH carrier frequency in the measurement result reports. In handover required messages sent from the BSC to the MSC, the preferred target cells for handover are identified by LAC (DMCS) resp. LAI (Ericsson) and CI. Therefore, in the BSC, the cell identification information provided by the MS has to be mapped onto the LAC/LAI and CI used to identify radio cells in the PLMN.

This parameter is used for power control and handover decision in the BSC. It is not sent to the MS but influences the power control commands for the MS. This parameter should be set to a value that is needed as maximum power level in the cell, i.e. that allows the MS to communicate with the BTS at every place in the cell even under bad radio conditions. For handover control this parameter is used for the power budget criterion. The power budget (PBGT) is a relative measure of the MS link power budget on a potential new link to a neighbour cell with respect to the current link in the serving cell. Basically, the MS should always communicate with or be handed over to the cell or BTS with the lowest possible link power budget. In the BSC, the PBGT of a given MS is calculated for every neighbour cell specified for the current serving cell. The calculation of the PBGT requires knowledge of the maximum allowed MS RF output powers MS_TXPWR_MAX on the dedicated channels of the respective neighbour cells and of the current serving cell that is given by this parameter.

Rx Level Access Minimum RADIO RXLEV This parameter defines the minimum received signal level at the MS required for access to the system. It is used together with other parameters to define the path loss criterion C1 for cell (re)selection (and C2 re-selection criterion). RXLEV_ACCESS_MIN is a part of the message System Information Type 3. This message is regularly broadcast on the BCCH by the network to all mobiles within the cell. Setting it to a high value means, that only those MSs are allowed to make an access attempt to the cell which are already in a location, where the reception of the Base Station is very good. This should result in an increased quality of the connection, but also in a decrease of the area of service availability. RXLEV_ACCESS_MIN shall be harmonised at least with L_RXLEV_XX_H and RXLEV_MIN(n).

Synchronized / Synch Identification NCELL CDESC-k Range:NOSYNC = 0, SYNC = 1, PRESYNC = 2, PSEUSYNC = 3 The synchronisation of a handover concerns the timing advance which has to be considered in incoming intercell handovers. Typically this is used for sectored cell configurations in order to accelerate the handover procedure. In order to enable a synchronised handover between synchronised radio cells, for every radio cell served by a particular BSC, this parameter contains the synchronisation state of all neighbour cells. The synchronisation state of the new cell with respect to the old cell is conveyed to the BSC serving the old cell via the handover request acknowledge and handover command messages on the BSC-MSC interface and is forwarded to the concerned MS in the old cell via the handover command message on the air interface. synchronised: the timing advance is given in advance; non-synchronised: the timing advance is given by the physical information message from the BTS; pre-synchronised: the timing advance is given in the handover command message or a default value is used. Phase 1 MSs do not support pre-synchronised and will be executed as non-synchronised. pseudo-synchronised: the timing advance is computed by the real time difference given in the handover command. Pseudo-synchronised is not supported and will be executed as non-synchronised if configured. This parameter is unique for the relation between a cell and a neighbour cell. Whether sychronised handover is possible between cells is dependent on the BTS type and physical configuration. See also PTA_HO(n,0) adjacentCellHandOverGSM0508 synchronized

Timer Periodic Update MS BTS CONFCCH-d Periodic updating may be used to notify periodically the availability of the MS to the network. Periodic updating is performed by using the location updating procedure. The timer is started when a signalling activity has taken place on the radio path. When the MS is powered down the timer value is kept in memory. When the MS is powered up the timer continues. When timer T3212 reaches its time out value, the MS initiates a location updating (Locataion Update Request) and the timer is restarted. Most service provider set this parameter to a high value to reduce load for BSC, MSC and VLR. The value 0 indicates that no periodic update should be used within the cell.

BSS MAP Timer in BSC: T7 BSC MAPT-7-b-c If the BSS has detected that a radio reason exists for a MSC controlled handover to occur, the BSS sends a HANDOVER REQUIRED message to the MSC. After sending this HANDOVER REQUIRED message the T7 timer is started. Radio Link Control will not produce further HANDOVER REQUIRED messages while the timer T7 is running. After receiving a HANDOVER COMMAND or HANDOVER REQUIRED REJECT message from the MSC the timer is stopped. On time out Radio Link Control resumes normal operation which may result in further Handover Required messages. Timer values smaller than 9 sec should be avoided (MSC is not able to do Handover Resource Allocation in second cell if first target cell fails) Timer values smaller than 4 sec are unusable (Handover Resource Allocation in first target cell probably not completed on receipt of second Handover Required message by MSC).

BSS MAP Timer in BSC: T8 BSC MAPT-8-b-c Handover execution in the context of the BSS/MSC interface is the process whereby an MSC instructs an MS to tune to a new dedicated radio resource which may be on a different cell. The HANDOVER COMMAND message is generated by the MSC and transmitted to the old BSS which is currently supporting the concerned MS. On receipt of the HANDOVER COMMAND message the T8 timer is started in the originating BSS. A radio interface HANDOVER COMMAND message is then sent by the old BSS, to the concerned MS. The message contains a handover reference number, previously allocated by the new BSS. The timer is stopped after receiving a Clear Command message with cause Handover Complete from the MSC. If the timer T8 times out, then the old BSS requests the release of the dedicated radio resources with a CLEAR_REQUEST message sent to the MSC. The timer is not restarted. Too low values: Resource in originating cell will be released even if MS has not completed the handover. The MS is not able to revert to the old cell. This results in a higher handover drop rate. Too high values: Higher resource usage in originating cell in case of quadruple fault (MS not seizing target cell and not reverting to old cell, TRR3 in target BSS not expiring, TRR7 in MSC not expiring).

0 0-7 10 * TEMPORARY_OFFSET dB, 7: infinite LO/UL TEMPORARY_OFFSET is a dynamic offset applied to a particular cell in order to discourage mobiles in idles mode from re-selecting this cell for a pre-defined period of time. The value of TEMPORARY_OFFSET is subtracted from a cells C1 value for a period of time defined by PENALTY_TIME. BTS TEMPOFF

Cell Reselection: Temporary Offset CELL C2CRIT-c TEMPORARY_OFFSET is a dynamic offset applied to a particular cell in order to discourage mobiles in idle mode from re-selecting the cell for a pre-defined period of time. The time for which this offset iss applied is defined by the PENALTY_TIME parameter and cen be set by the operator. The C2 reselection criteria is reduced by TEMPORARY_OFFSET during this time. When the C2 criterion is employed, a TEMPORARY_OFFSET is typically applied to Lower Layer cells for the period in which they are classified as 'fast' moving. Once a mobile is considered to be 'slow' moving the TEMPORARY_OFFSET can be removed. The use of TEMPORARY_OFFSET (in association with PENALTY_TIME) can therefore be used to encourage 'slow' moving mobiles to re-select Lower Layer cells, whilst discouraging 'fast' moving mobiles from 'camping-on' this cell layer. A TEMPORARY_OFFSET is not typically applied to Upper Layer cells. The value of TEMPORARY_OFFSET should be chosen according to the size of the cell and the cell layers. See also CELL_RESELECT_PARAM_IND, CELL_RES_OFFSET, PENALTY_TIME. These parameters specify the criteria for cell reselection according to the C2 criteria for GSM phase 2 MS. -

Radio Link: Fail Warning RADIO RLFW During each call, the radiolink (Um) is monitored for successful message decoding on the SACCH. If a single SACCH block could not be decoded a timer (initialised with RADIO_LINK_TIMEOUT) is decremented by 1, if it could be decoded it is incremented by 2 not exceeding the threshold given in RADIO_LINK_TIMEOUT. If the timer gets equal or lower than THRES_PC_RLF, the 'radio link failure warning' alarm occurs and the transmitter power of both BTS and MS are set to maximum.

5dB = 5 0-31 0-31dB LO/UL Hysteresis value used as part of the 'layer down receive level', TH5 condition for initiating a 'layer down' handover from an upper (Upper or Middle) to a lower (Middle or Lower) layer cell. HOCTRL UMBHYST

Umbrella Cell Hysteresis HO HOUMBRCELL-a The UMBRELLA_MICRO_HYST parameter can be used to influence the receive level 'entry threshold' to lower layer cells before a 'layer down' handover can be executed. After channel allocation on a SDCCH of a Middle or Upper Layer cell the duration of stay of the MS in the coverage area of a lower layer NC is measured using the Cdosnc(n) counter. The Cdosnc(n) counter is incremented by 1 if the averaged receive level for a particular lower layer cell is greater than the TH5 condition, defined by; AV_RXLEV_NCELL_S(n) > RXLEV_MIN(n) + TH5(n) Where; TH5 = UMBRELLA_MICRO_HYST + 2*MAX(0,P-MS_TXPWR_MAX(n)) Otherwise it is decremented by 1. The counter is also decremented by 1 if no rxlev measurements are received for that SACCH frame. If the duration of stay in a lower layer NC, Cdosnc(n), reaches its threshold defined by C_UMBRELLA_MICRO_HO a 'layer down' handover is triggered. See also CELL_TYPE, CELL_TYPE_NC, C_UMBRELLA_MICRO_HO, C_MICRO_HO and C_MICRO_DELAYED_HO -

1 1-3 LO/UL The weighting factor is applied to handover control signal quality measurements to account for effects of DTX (discontinuous transmission) during averaging process. HOCTRL WQUALHO

Signal Quality: Weighting Factor HO HOCSQ-d This parameter specifies the weight of full-set quality measurements with respect to sub-set quality measurements in the averaging process. The effective averaging period is reduced by the weighting factor if DTX is not active. W_QUAL_HO and A_QUAL_HO should be considered together to get a meaningful averaging period. The recommended default value applies for disabled DTX. With DTX enabled the weighting factor for Full measurements should be set to 2. To get a effective window size of 4 the recommended default value for A_QUAL_HO with DTX enabled is 8.

1 1-3 LO/UL The weighting factor is applied to power control signal quality measurements to account for effects of DTX (discontinuous transmission) during averaging process. POWER WQUALPC

Signal Quality: Weighting Factor PC SQWF This parameter specifies the weight of full-set quality measurements with respect to sub-set quality measurements in the averaging process. The effective averaging period is reduced by the weighting factor if DTX (discontinuous transmission) is not active. If DTX is used, the power measurements are not very reliable. W_QUAL_PC and A_QUAL_PC should be considered together to get a meaningful averaging period. -
