hello,
are the complaints about one cell or many cells ?
are the cells using ABIS over satellite ?
I don’t think the immediate assignment is the problem (this is a very rare problem), but you can check the qos statistics in order to determine more precisely the nature of the problem. Can you give me the following values at busy hour, for the worst cells encountering this problem ?
SDCCH assignement unsuccess rate = ?
– due to radio ?
– due to congestion ?
– due to bss problem ?
SDCCH drop rate = ?
– due to radio ?
– during handover ?
– due to bss problem ?
TCH assignment unsuccess rate = ?
– due to radio ?
– due to congestion ?
– due to bss problem ?
TCH drop rate = ?
– due to radio ?
– during a handover ?
– due to bss problem ?
what is the average duration of a SDCCH seizure and of a TCH seizure ?
Regards,
