Parameter Name |
TCH Minimum Recovery Time(s) |
|---|---|
Description |
This parameter specifies the minimum time for the recovery of a TCH from an SDCCH. The processing for the SDCCH recovered to the TCH is as follows: each cell is configured with a counter. Each time the TCH is converted to the SDCCH, the counter is set to ResTime. The value of the counter is adjusted every three seconds. If the number of idle SDCCHs > 8 + N1, the counter descreases by 3; if the number of idle SDCCHs < 8 + Idle SDCCH Threshold N1, the counter increases by 12 within the setting value; if the number of idle SDCCHs = 8 + N1, the counter remains unchanged. If the value of the counter is equal to or lower than 0 after adjustment, the SDCCH is converted to the TCH. |

Configuration Policy |
If this parameter is set too small, it cannot correctly indicate the idle state of the current SDCCHs and consequently the rollback of SDCCHs immediately triggers adjustment and affects the network performance. If this parameter is set too large, the channel allocation algorithm becomes less sensitive and consequently the SDCCHs stay in idle state and cannot be rolled back for a long period of time. |
