Q. How to do improve the TCH assignment Success Rate of GSM Cells for ZTE equipment? What parameters to do change in order to improve this KPI
A. 1. We can gain better rates by changing Half Rate / Full Rate discrimination levels. Further more little amount of TCH congestion can be overcome by changing SDD time slot to TCH.
2. focus on removing tch congestion...chk for hardware issues.
3. Make sure that it is a radio issue sometimes can be abis interface congestion and we can also try increasing the RxLevAccessMin, it is the easiest way, but not necessarily the right one. First try to improve the RF environment through physical optimization
