Dears,
I have doubts that the congestion over the Abis could cause Sudden lost connections, TCH congestion, SDCCH congestion and PDCH Failure. but I need to measure the congestion over the Abis whenever its Flex or Abis optimization.
Does any one know how to do it for E******* ?
Thanks ...

hi dear
in E******* we can measure congestion over ABIS which causes TCH/TBF rejection by bellow formulas :
for CS : "case when (TFCALLS + THCALLS) != 0 then
100 * OVERLOADREJCON / (TFCALLS + THCALLS)
end"
For PS : "case when (PREJABISCONG + PREJTFI + PREJOTH+MSESTULTBF) != 0 then
100 * PREJABISCONG / (PREJABISCONG + PREJTFI + PREJOTH+MSESTULTBF)
end"

Thanks Amir
when I applied the formulas I got the results as in the attached pic ... the strange thing that there is Abis PS congestion while there is NO Abis CS congestion
and one more question ... as I found in the Alex that the CS formula used for Packet Abis (Abis optimization) so does the same formula still valid for the Flex Abis ?

also about second question yes it is valid

Dear
Iam new in E******* and swap started in my network so that I have to check what I did for Huawei for Abis dimensioning the same to do for E******* , Can I have your help how to check the distribution of Abis time slot between cs and ps , and if the What parameter can show me it is Abis over tdm or ip?
If there is as well guideline would be grate.
Thanks for help

Hi all what you have to do is to display free time slots then assign EDGE time slots distributing them among TG cells.
Use rxapp:moty=rxotg;
Based on TRX configration you can assign no of FPDCH.

The command run on OPS but gives none value.
