Increased Traffic Volume 

A large number of users initiate PS services at the same time, leading to resource congestion. As a result, the PS RAB setup fails.



The RAB setup success rate decreases and the values of VS.RAB.FailEstabPS.Cong or VS.RAB.FailEstabCS.Cong increase noticeably.

The number of CS RAB setup attempts or PS RAB setup attempts increases noticeably.


The following analysis is based on the period when the fault occurs.


Analyze the number of online UEs. Check whether the values VS.CellDCHUEs.RNC and VS.CellFACHUEs.RNC increase noticeably.


Analyze the number of CS RAB setup attempts or PS RAB setup attempts in each cell. Check whether the numbers increase drastically in some cells.


Check whether there are any network behaviors influencing the current traffic model.


Check whether the number of service requests initiated by a certain type of UE increases drastically on the CN side.
