If the built-in PCU is used. The load handover algorithm is used to hand over the MSs out of a cell step by step. the number of the dynamic PDCHs that can be preempted is always zero. the enhanced load handover is used to balance load of cells in a network. the dynamic PDCHs that can be preempted are considered as idle TCHs in the cell load. The enhanced load handover is applicable to the scenario where multiple base stations are located at the same place. the trigger conditions for an enhanced load handover are as follows: The CPU usage of the current system is smaller than or equal to SYSFLOWLEV. After a LOADHOPERIOD elapses. the possibility of low level and congestion due to heavy load in the target cell after the handover is minimized. In this way. the enhanced load handover considers the handover quality and the load in the target cell before the handover is performed. 3. The number of the dynamic PDCHs that can be preempted depends on the number of dynamic PDCHs and DYNCHNPREEMPTLEV. When LOADSTATYPE is set to 0. 2.

The load of the serving cell is greater than TRIGTHRES. the calculation method of the cell load depends on the setting of LOADSTATYPE. The load handover stops when the traffic volume in the cell is less than or equal to TRIGTHRES. The load handover margin 2 specifies the area where the downlink level ranges from DLEDGETHRES to the sum of DLEDGETHRES and (2 x LOADHOSTEP). Here.GSM BSS Handover 3 Technical Description Examples The system assigns MSs to different load handover margins based on the downlink receive level. The number of dynamic PDCHs is the total number of channels whose CHTYPE is set to FULLTCH. Target Cell Selection When a candidate cell satisfying the following conditions is found and not a single MS within the range specified by LOADHOUSRRATIO is handed over to the target cell. The MSs in load handover margin 1 are handed over to the neighboring cells.

Trigger Conditions for an Enhanced Load Handover If LOADHOAD is set to YES. the dynamic PDCHs that can be preempted are considered as occupied TCHs in the cell load. 1. further search of the target cell is stopped and current traffic is handed over to the candidate cell. The setting of the parameter determines whether the dynamic PDCHs that can be preempted are considered as occupied channels.4. The setting of LOADSTATYPE is irrelevant to calculation of the cell load. The load handover is performed step by step to prevent call drops caused by a sudden increase in CPU load or the congestion in the target cell. 3. the dynamic PDCHs that can be preempted are not considered in the cell load. 3-21 . Receive level of a neighboring cell > Receive level of the serving cell + (INTERCELLHYST – 64) An edge handover is triggered when the P/N criterion is met. This regulation prevents too many MSs from being handed over to the target cell at one time and avoids congestion in the target cell. EDOUTHOADEN and EDOUTHOOFFSET are invalid.

Issue 04 (2012-06-30) Huawei Proprietary and Confidential Copyright © Huawei Technologies Co., Ltd. 3-32 GSM BSS Handover 3 Technical Description Quick handover aims to increase the handover success rate of an MS moving at a high speed and to ensure the call continuity and low call drop rate. Quick handover applies to the scenario where an MS moves fast along an urban backbone road, a selected route, or a high-speed railroad. Quick Handover Types Quick handover consists of frequency offset handover and quick PBGT handover. Frequency offset handover Whether the MS is moving away from the serving cell is determined based on the frequency offset information provided by an MS moving at a high speed. Frequency offset handover decision is made according to the uplink/downlink receive level of the serving cell and the path loss of neighboring cells. Quick PBGT handover Quick PBGT handover decision is made according to the path loss of neighboring cells. For quick handover, the handover response speed is enhanced by: Accurately calculating the moving speed of the MS Lifting the restriction on the interval between handover decisions Reducing the number of MRs for the handover decision Introducing the alpha filtering Quick Handover Preparation The preparation for quick handover involves the following aspects: Frequency offset is decoded from the MR. Frequency offset of the MS is obtained from the uplink MR that the BTS sends to the BSC. Alpha filtering is performed on the MR. Trigger Conditions During handover decision, it is first determined whether the trigger conditions for a frequency offset handover are met. When the BTS cannot send the frequency offset information or the reported frequency offset information is invalid, quick PBGT handover is triggered, provided that other conditions for a frequency offset handover are met. If QUICKHOEN is set to Yes, the trigger conditions for a quick handover are as follows: The MS is moving away from the serving cell (the frequency offset in the measurement result is a negative value) and the moving speed of the MS is greater than MOVESPEEDTHRES. The filtered uplink level of the serving cell is smaller than HOUPTRIGE. The compensated downlink level of the serving cell is smaller than HODOWNTRIGE. The path loss of configured chain neighboring cells is smaller than the specified threshold of the path loss of the serving cell. The trigger conditions for a quick handover are as follows: If the last three conditions are met simultaneously, the decision is made as follows: − If the first condition is met, a frequency offset handover is performed. − If the first condition is not met, a quick PBGT handover is performed. If all the last three conditions are not met, quick handover is not triggered. Issue 04 (2012-06-30) Huawei Proprietary and Confidential Copyright © Huawei Technologies Co., Ltd. 3-33 GSM BSS Handover 3 Technical Description Target Cell Selection The target cell must be a chain neighboring cell of the serving cell. The target cell can be obtained through the setting of ISCHAINNCELL. If HODIRFORECASTEN is set to Yes, a neighboring cell in the moving direction of the MS is selected preferentially. To forecast the moving direction of the MS, the direction of a chain neighboring cell (A or B) compared with the serving cell is specified by CHAINNCELLTYPE. If the number of times that the MS is handed over to neighboring cells in the same direction (B for example) is greater than or equal to HODIRLASTTIME when the handover time reaches HODIRSTATIME, the MS is inferred to be moving towards the B direction. Subsequently, the MS is preferentially handed over to the neighboring cell whose CHAINNCELLTYPE is B. Limitations The limitations on quick handover are as follows: The serving cell cannot be selected as the target cell. The candidate cells for quick handover must be chain neighboring cells of the serving cell. After a quick handover is successful, the penalty is performed on the original cell during the penalty time to prevent an immediate handover back to the original cell. The penalty time and penalty value are specified by TIMEPUNISH and HOPUNISHVALUE respectively. 3.5.2 TA Handover TA handover is a type of emergency handover. The TA handover decision is made according to the TA value reported by the MS. The TA value of a normal cell ranges from 0 to 63 and that of an extended cell ranges from 0 to 229. The TA can be stepped up or down in steps of 553.5 m. The TA value of 63 corresponds to a distance of 35 km. Trigger Conditions TA handover is triggered when the following conditions are met: TAHOEN is set to Yes. Filtered TA value in the MR provided by the MS is greater than or equal to TALIMIT. The TA handover can be triggered only when the preceding two conditions are met simultaneously. From the perspective of the trigger conditions for a TA handover, TA can be regarded as a limitation to the size of a cell. Target Cell Selection The target cell must have the highest priority in the candidate cell list after handover preprocessing. In addition, the target cell must meet the following conditions: The serving cell cannot be selected as the target cell. If TALIMIT of a co-site neighboring cell is smaller than or equal to the TALIMIT of the serving cell, a handover to the neighboring cell is prohibited. In handover algorithm II, a cell becomes the target cell for TA handover if the previous conditions are met for TALASTTIME within TASTATTIME. If the trigger conditions for a TA handover are met but the candidate 2G cells are not suitable, the following operations are performed: Issue 04 (2012-06-30) Huawei Proprietary and Confidential Copyright © Huawei Technologies Co., Ltd. 3-34 GSM BSS Handover 3 Technical Description If a neighboring 3G cell is available, if INTERRATOUTBSCHOEN is set to Yes, and if the MS supports the 2G/3G inter-RAT handover, the 2G/3G inter-RAT handover is performed. If no neighboring 3G cell is available, if INTERRATOUTBSCHOEN is set to No, or if the MS does not support the 2G/3G inter-RAT handover, the decision on whether to initiate another type of emergency handover is made. Limitations After the TA handover is successful, the penalty is performed on the original cell. During TIMETAPUNISH, SSTAPUNISH is subtracted from the level of the original cell to prevent an immediate handover back to the original cell. 3.5.3 BQ Handover BQ handover is a type of emergency handover in which the system makes the decision based on the uplink/downlink receive quality on the Um interface. Receive quality is represented by BER. The BSC measures the quality of a radio link based on the quality band in the MR. The probable cause of an increase in BER is that the signal power is too low or the channel interference increases. Trigger Conditions If BQHOEN is set to Yes, the trigger conditions for a BQ handover are as follows: The uplink receive quality is greater than or equal to the uplink receive quality threshold of the serving cell. The downlink receive quality is greater than or equal to the downlink receive quality threshold of the serving cell. The BQ handover is triggered when either of the preceding conditions is met. The parameters for specifying the uplink and downlink receive quality thresholds are as follows: For non-AMR calls, the parameter for specifying the uplink receive quality threshold is ULQUALIMIT and the parameter for specifying the downlink receive quality threshold is DLQUALIMIT. For AMR FR calls, the parameter for specifying the uplink receive quality threshold is ULQUALIMITAMRFR and the parameter for specifying the downlink receive quality threshold is DLQUALIMITAMRFR. For AMR HR calls, the parameter for specifying the uplink receive quality threshold is ULQUALIMITAMRHR and the parameter for specifying the downlink receive quality threshold is DLQUALIMITAMRHR. Target Cell Selection The target cell must have the highest priority in the candidate cell list after handover preprocessing. In addition, the target cell must meet the following conditions: In handover algorithm II, the serving cell cannot be selected as the target cell. The receive level of target cell must meet the following conditions: − The serving cell and the target cell work in the same frequency band.

There is no constraint on the target cell in this condition. In handover algorithm II, a cell becomes the target cell for BQ handover if the previous conditions are met for BQLASTTIME within BQSTATTIME. If the trigger conditions for a BQ handover are met but the candidate 2G cells are not suitable, the following operations are performed: If a neighboring 3G cell is available, if INTERRATOUTBSCHOEN is set to Yes, and if the MS supports the 2G/3G inter-RAT handover, the 2G/3G inter-RAT handover is performed. If no neighboring 3G cell is available, if INTERRATOUTBSCHOEN is set to No, or if the MS does not support the 2G/3G inter-RAT handover, the decision on whether to initiate another type of emergency handover is made. Limitations After the BQ handover is successful, the penalty is performed on the original cell. During TIMEBQPUNISH, SSBQPUNISH is subtracted from the level of the original cell to prevent an immediate handover back to the original cell. 3.5.4 Interference Handover Interference handover is a type of intra-cell handover in handover algorithm II. Interference handover helps protect the interfered calls and reduce the network interference. It is applicable to scenarios with interference.

Issue 04 (2012-06-30) Huawei Proprietary and Confidential Copyright © Huawei Technologies Co., Ltd. 3-42 GSM BSS Handover 3 Technical Description Huawei multiband handover algorithm divides cells into four layers, with 16 priorities at each layer. The LAYER parameter specifies at which layer a cell is located. This algorithm is applicable to complex networking scenarios. Figure 3-14 shows the cell layers. Figure 3-14 Cell layers GSM900 Layer 4 Umbrella Cell GSM900 GSM900 GSM900 Macro Cell Layer 3 DCS1800 DCS1800 DCS1800 Micro Cell Layer 2 GSM900 DCS1800 GSM900 GSM900 GSM900 DCS1800 DCS1800 DCS1800 Pico Cell Layer 1 In Huawei multiband handover algorithm, a GSM network covering a certain area is divided into four layers, which are: Layer 4: Umbrella cell. The umbrella cells are generally GSM900 cells having the wide coverage feature. It also implements fast MS connection. Layer 3: Macro cell. The macro cells are generally GSM900 cells, which are commonly used in current GSM system and serve majority of subscribers. Layer 2: Micro cell. The micro cells are generally DCS1800 cells having the small coverage feature. They enable capacity expansion. Layer 1: Pico cell. The Pico cells are generally DCS1800 cells, which are used in hot spots and blind spots. The cell at the lower layer has a higher priority. PRIOR controls a handover between cells at the same layer. Each layer has 16 priorities, numbered 1-16 respectively. A high value indicates a low priority. If the cells at the same layer have different priorities, a cell with a smaller priority value has a higher priority. PRIOR along with CELLLAYER determines the priority of a cell. The priority affects the sequence of neighboring cells for handover. 3.5.10 Better-Cell Handover Better-cell handover is an optimization of inter-layer handover and PBGT handover in handover algorithm I. Better-cell handover is specific to handover algorithm II.

If PATHLOSSHOEN is set to No, path loss is not taken into consideration during the sorting of the serving cell and handover candidate cells. If the serving cell is in the candidate cell list, the priorities of the handover candidate cells must be higher than the priority of the serving cell after the sorting. If the serving cell is not in the candidate cell list, the handover candidate cells must meet the following conditions: − LoadHoEn is set to NO, or LoadHoEn is set to YES but the load in the serving cell is smaller than TRIGTHRES. − If the serving cell and the handover candidate cells are at the same layer and have the same priority, the following conditions must be met: SS_DL(N) - SS_DL(S) > H - 64 SS_DL(N) indicates the filtered BCCH receive level of a target cell. SS_DL(S) indicates the compensated receive level on the downlink TCH after filtration. H indicates INTERCELLHYST of the serving cell over the neighboring cell. Negative handover is a type of better-cell handover. When INTERCELLHYST is set to a value smaller than 64, the value of H – 64 is negative. In this case, even if the downlink receive level in a candidate cell is smaller than the downlink receive level in the serving cell, a negative handover to the candidate cell can be performed. − If the serving cell and the handover candidate cells are at different layers but have the same priority, the following conditions must be met: SS_DL(N) ≥ T_layer(N) + H_layer(S) SS_DL(N) indicates the filtered BCCH receive level of a target cell. T_layer(N) indicates HOTHRES of the target cell. H_layer(S) indicates INTELEVHOHYST of the serving cell. − If LoadHoEn is set to YES and the load in the serving cell is greater than TRIGTHRES, better-cell handover can be triggered. A neighboring cell becomes a target cell if the preceding conditions are met for BETTERCELLLASTTIME during BETTERCELLLASTTIME. If both EDOUTHOADEN and NCELLPUNEN are set to No for the target cell, a better-cell handover is triggered when the previous conditions are met. If EDOUTHOADEN is set to Yes for the target cell, a better-cell handover is triggered when the previous conditions and the following condition are met: Filtered downlink receive level of the serving cell after power control compensation ≥ HOTHRES – (LEVHOHYST + EDOUTHOOFFSET – 64) If NCELLPUNEN is set to Yes for the target cell, the timer NCELLPUNTM is started. After the timer is started, the value of NCELLPUNLEV is subtracted from the filtered receive level of the target cell. If the timer expires, a better-cell handover is triggered. If the timer stops, no better-cell handover is triggered. The timer stops when the filtered BCCH receive level of the target cell is smaller than the value of NCELLPUNSTPTH. Target Cell Selection The requirements for target cell selection are as follows: The serving cell cannot be selected as the target cell. The target cell has the highest priority in the candidate cell list. 3.5.11 Handover Between a Full-Rate TCH and a Half-Rate TCH This section describes the feature GBFD-115522 Dynamic HR/FR Adaptation.
