A configuration command that modifies the emergency handover parameters of the cell. In this command, Cell Index or Cell Name uniquely identifies a cell.
ID | Name | Description |
---|---|---|
IDXTYPE | Index Type | Meaning:Index Type Value range:BYNAME(By Name),BYIDX(By Index) Explanation:Index Type. Default value:None |
CELLIDX | Cell Index | Meaning:Cell Index Value range:0~2047 Explanation: This parameter indicates the source cell index. The source cell index must be unique. Default value:None |
CELLNAME | Cell Name | Meaning:Cell Name Value range:1-32 characters Explanation: This parameter indicates the name of the source cell. The name of each cell under one BSC must be unique. Default value:None |
HOCTRLSWITCH | Current HO Control Algorithm | Meaning:Current HO Control Algorithm Value range:HOALGORITHM1(HO Algorithm I),HOALGORITHM2(HO Algorithm II) Explanation:This parameter specifies whether HO Algorithm I or HO Algorithm II is valid. Default value:None |
TALIMIT | Emergency Handover TA Threshold | Meaning:Emergency Handover TA Threshold Value range:0~255 Explanation:An emergency handover is triggered when TA is greater than or equal to the value of this parameter. Default value:None |
DLQUALIMIT | DL Qual. Threshold | Meaning:DL Qual. Threshold Value range:0~70 Explanation:This parameter specifies the downlink receive quality threshold of an emergency handover. An emergency handover is triggered when the downlink receive quality is greater than or equal to the DL Qual. Threshold. When an emergency handover is triggered, an inter-cell handover should be preferentially selected. An intra-cell handover, however, is triggered if no candidate cell is available and if intra-cell handovers are allowed. Default value:None |
ULQUALIMIT | UL Qual. Threshold | Meaning:UL Qual. Threshold Value range:0~70 Explanation:This parameter specifies the uplink quality threshold of an emergency handover. An emergency handover due to bad quality is triggered when the uplink receive quality is greater than or equal to the UL Qual. Threshold. When an emergency handover is triggered, an inter-cell handover should be preferentially selected. An intra-cell handover, however, is triggered if no candidate cell is available and if intra-cell handovers are allowed. Default value:None |
FLTPARAA1 | Filter Parameter A1 | Meaning:Filter Parameter A1 Value range:0~20 Explanation:This parameter is used for configuring the filter for the rapidly dropped receive level. Together with filter parameter B, it is one of the nine filter parameters. The corresponding formula is as follows (in the program, the value of A1 to A8 can be obtained by subtracting 10 from the configured value, and B is the negative value of the configured value): C1(nt) = A1 x C(nt) + A2 x C(nt-t) + A3 x C(nt-2t) +...+ A8 x C(nt-7t). Where, C(nt) is the uplink RX_Level of the serving cell in the MR received at the time of nt. If C1(nt) is smaller than B, and if C(nt) is below the Edge HO RX_LEV Thrsh., then the signal level is considered to be rapid dropping. Filter parameters A1 to A8 may be smaller than or equal to 10. Parameters A1 to A8 correspond to a1 to a8 in the program, and ai = Ai-10 (i = 1-8). Therefore, among a1 to a8 in the program, there must be values smaller than or equal to 0. For example, if the receive level drops rapidly in a granularity period, you need to set A3 to A8 to 10, A1 to 0, and A2 to 20. In this case, C1(nt) = a1 x C (nt) + a2 x C(nt-t) = 10C(nt-t)-10C(nt). To trigger a rapid level drop handover, you should set C1(nt) to a value smaller than B. and then the fast level drop appears in a MR period. The formula reflects the rapid drop of the cell level in an MR. You can configure the filter to define the number of MRs used and the extent to which the level drops. However, the setting of this parameter is complicated. Default value:None |
