Is there someone can help me to fix IASR issue. CSR is going down on BH (18h to 22h). Sometime there is LAPD Link Congestion alarm on the concerned sites.
Even the ratio of Attempted Imm Ass by Succussful Imm Ass is going down on BH, too much attempted failed on SDCCH and TCH on BH.
Thanks in advance for your support!
Thx Pix for your support.
The Poor SD is due to high traffic on Busy Hour (6pm to 10pm).
I’ll try to increase Tch HR usage and reduce Ts packet transfer but other actions have already done.
Thanks alot to each of you for your support.
I am happy to inform you that i fixed the issue about poor SDCCH Acc by changing the Multiplex Mode from 2:1 to 1:1 and add 1 more E1 because the issue was LapDLink congestion during Busy Hour.
Now my KPIs are looking very good
CSR from 40% to 99% for the concerned cells.
Again, thanks alot to all of you.
