Parameter Name |
BQ HO Margin |
|---|---|
Description |
The handover to an adjacent cell occurs when the difference between the downlink level of the adjacent cell after filtering and the downlink level of the serving cell (after power control compensation) > the Inter-cell HO hysteresis - the BQ HO Margin + 64. The handover to the adjacent cell whose level is lower than that of the serving cell (after power control compensation) can be performed, when the Inter-cell HO hysteresis is less than the BQ HO Margin. It is recommended that you set this parameter to approximately 69 in densely-populated urban areas and 72 in suburban areas. The level values 0 to 127 map to -64 dB to 63 dB. |

Configuration Policy |
The difference between Inter-cell HO Hysteresis and BQ HO Margin is used to filter the candidate cells. If the BQ HO Margin is set to a higher value, the threshold for the candidate cells is lowered, thus an adjacent cell is more likely to become a target cell for handover. |

Caution |
By default, the value of this parameter is 5 when the data of M900/M1800 BSC is upgraded to the BSC6000. Modify this value to 69; otherwise, the handover algorithm supported by this parameter is invalid. |
