Hello Pix,

Thank you very much for your help. 🙂

I managed to extract the counters for RACH phase (request) and SDCCH establishment(establi)

Here are two tables for two different days of the same cell: one with the values of the counters when the rate of SDCCH establishement is ok and the other one when the rate is not ok.

EASDCCH assignment ok:

|request | establ | Difference
———————————–
MO | 718 | 631 | 87
LU | 11870 | 11378 | 492
MT | 823 | 780 | 43
SMS | 474 | 218 | 256
EC | 13 | 1 | 12
———————————–
Total| 13898 | 13240 | 658 (CESSTIMMASS)

EASDCCH assignment not ok:

|request | establ | Difference
———————————–
MO | 593 | 504 | 89
LU | 13613 | 11030 | 2583 => probleme
MT | 835 | 741 | 94
SMS | 456 | 156 | 300
EC | 10 | 3 | 7
———————————–
Total| 15507 | 12686 | 2821 (CESSTIMMASS)

*EC = emergency call

As you can see, the problem appears for Location Update.

I have one more question: Are really the RACH phantom counted as LU requests?

Thanks in advance.
