Parameter Name |
Idle SDCCH Threshold N1 |
|---|---|
Description |
If the number of idle SDCCHs in the cell is smaller than or equal to the value of this parameter, the BSC tries to find a TCHF that can be converted to the SDCCH. This parameter specifies one of the conditions for converting the TCHF to the SDCCH. Besides this parameter, the other three conditions for initiating the conversion from TCHFs to SDCCHs are as follows: 1.The cell allows the SDCCH dynamic adjustment. 2.(Number of idle TCHFs + number of idle TCHHs/2) ≥ 4 or the number of TRXs in the cell, and the cell must have at least one idle TCHF. 3.The sum of the number of SDCCHs in the cell plus eight is smaller than the maximum number of SDCCHs allowed in the cell. |

If this parameter is set too large and consequently there is a small number of requests for SDCCHs, the SDCCHs of a cell are in idle state; If this parameter is set too small and consequently there is a large number of requests for SDCCHs, the requests cannot meet the requirements. |
