These High RRC Failures are on Signalling or Service?
I am new on Huawei. Any counter to categorized this on U2000?
Also there was huge traffic increase at the same time.
Check these counters in PRS:
Do you have transmission capacity problems?
Can you do IP Path measurement?
Or flow control / congestion?
Is there LTE CSSR improvement Parameter list suggestions?
Where’s your failing?
On RACH, on RRC or on ERAB?
What’s the main cause of failure?
RRC and ERAB.
Our CSSR formula contains RRC, ERAB and S1sig.
Right, S1 shoudl be there too.
