NetAct name: RRC_CONN_STP_FAIL_ICSU_OVERL

Description: The number of RRC setup failures caused by ICSU overload.

When the RNC decides to reject the RRC connection request due to ICSU overload. After this, the RNC
sends an RRC: RRC CONNECTION REJECT message to the UE.

inter-system handovers and inter-RNC hard handovers

RRC ACC FAIL DUE TO UU INT

NetAct name: RRC_CONN_ACC_FAIL_MS

Description: The number of RRC access failures caused by UE.

When the RNC does not receive the RRC: RRC CONNECTION SETUP COMPLETE message from the UE
within 6 seconds, and the RNC has received the NBAP message which indicates that L1 synchronisation
has been established between UE and BTS. This counter is updated also in case of incoming SRNS
relocations, inter-system handovers, and inter-RNC hard handovers

RRC ACC FAIL DUE TO RNC INTER REASONS

NetAct name: RRC_CONN_ACC_FAIL_RNC

Description: The number of RRC access failures caused by RNC internal reason.

When an RNC internal failure occurs before receiving the RRC: RRC CONNECTION SETUP COMPLETE
message from the UE. This counter is updated also in case of incoming SRNS relocations, inter-system
handovers, and inter-RNC hard handovers
