Network Performance and Operation

  Accessibility  :If A UE Requested for the some services to the system and System will Response UE Properly, It means Accessibility is  completed successfully. Accessibility KPIs are used to measure how successfully user is able to access the Network. Divided in 3 segments. RRC Phase S1 Signaling Phase E-RAB Phase In the Call Flow System, after the RACH Procedure,2nd Procedure comes the RRC Phase. RRC Rejection due to Congestion: May be the Reason eNB will be busy or it is very congested, It don't have Resources, So that it can allow new user.                                                How we can Reduce the Congestion Decrease the UE Inactive Timer to a smaller value( If we reduce this timer, UE will less stay in RRC connected mode, more offen release by enb) . This will initiate early release for the users, Hence Load will be reduced. However this can increase the signaling load as idle user can try to come back to network more frequently which can increase CPU usage of the e
