T3109

[mamta]

i found in one of HUAWEI documents that T3109 improves call drop rate, i want to make sure of this, and what is the exact impact of T3109. here is the part of the document:

1. Timer T3109

This parameter specifies the period for waiting for a Release Indication message after the BSC sends a Channel Release message to the BTS. If this parameter is set to a too small value, the link may be released before the Release Indication message is received. As a result, a call drop occurs. You can set this parameter to a greater value to reduce the TCH call drop rate. It is recommended that timer T3109 be set to 1–2 seconds longer than timer

precaution to be taken while setting T3109. T3109 value must be higher than RLT timer.
