low Tch Completion Rate
Dear Genious,
I facing low tch completion rate in 15 cells of cluster .
which effect overall Performance of cluster,so main reason i got is these cells are low utlize(less 15%,avrtraffic:-lessthan 1 erlg).
I need sujestion from your side how can i overcome from these probleum (except-antenna re orientaion)
FYI:-SYSTEM IS Huawei.
plz help

1- check the any HW problem .
2- CGI is correct in both BSS and NSS.

Hi Rajmeena,
Have u check TCH Allocation/Performance Rate, it can be collected in BSC6000...there u can calculate TCH performance based on completed over attempted..

hey tru to tune power control it will improve c/I performance hence assignment rate.
search for my huawei power control post i have posted the PC fine tuned values. they are for 6900. try to relate with 6000.

Re: low Tch Completion Rate
Please check TRX wise TCH assignment request and success in M2000 in problem cells
Low TCH assignment can happen with
1. Hardware issues ( VSWR..)
2, Hardware configuration issues
3. Interference
4. UL and DL power mismatch
5. immediate access allowed threshold with very low setting
etc
isolate the problem with frequency, cell, TRX, time and analyse the reason

Since the traffic is very low on these cells and also the drop rate is high, it is possible that the Coverage is poor for these cells or the neighbor definitions are not proper. You may check these. If it does not resolve the problem try checking if the RxLev Access min is set to high value. Because if this is high then the chances of MS accessing these cells are less. Also since a group of cells are being affected by this, the interference could also be a reason.
