Reply To: Imm_Ass_Succ_Rate

Hello,
Would like some advise:
customer complaints on hard to setup a call:
– low immediate assignment success rate
– relatively high SDCCH successful seizure
– Low SDCCH & TCH congestion.

Initially thought there might be insufficient AGCH assigned.

After checking parameters:
AG reserved = 2 blocks
T3101 = 3s
CCCH = non-combined

Right now haven’t received alarm history logs & drive test results

What else could be the cause? Any suggestions?

Thank you
