RRC setup failuresRRC SETUP FAIL DUE TO HC

NetAct name: RRC_CONN_STP_FAIL_HCDescription: The number of RRC setup failures caused by Handover Control.

When the RNC decides to reject the RRC connection request because the handover control entity reports a failure. After this, the RNC sends an RRC: RRC CONNECTION REJECT message to the UE.

This counter is updated also in case of incoming SRNS relocations, inter-system handovers, and inter-RNC hard handovers

RRC SETUP FAIL DUE TO AC

NetAct name: RRC_CONN_STP_FAIL_ACDescription: The number of RRC setup failures caused by Admission Control.

When the RNC decides to reject the RRC connection request because the admission control entity reports a failure (excluding frozen BTS reason).

After this, the RNC sends an RRC: RRC CONNECTION REJECT message to the UE. This counter is updated also in case of incoming SRNS relocations, inter-system handovers, and inter-RNC hard handovers

RRC SETUP FAIL DUE TO BTS REASONS

NetAct name: RRC_CONN_STP_FAIL_BTSDescription: The number of RRC setup failures caused by BTS.

When the RNC decides to reject the RRC connection request due to unsuccessful radio link setup. After this, the RNC sends an RRC: RRC CONNECTION REJECT message to the UE.

This counter is updated also in case of incoming SRNS relocations, inter-system handovers, and inter-RNC hard handovers

RRC SETUP FAIL DUE TO TRANS

NetAct name: RRC_CONN_STP_FAIL_TRANSDescription: The number of RRC setup failures caused by Transport.

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

This counter is updated also in case of incoming SRNS relocations, inter-system handovers, and inter-RNC hard handovers

RRC SETUP FAIL DUE TO RNC INTER REASONS

NetAct name: RRC_CONN_STP_FAIL_RNCDescription: The number of RRC setup failures caused by RNC internal reason.

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

This counter is updated also in case of incoming SRNS relocations, inter-system handovers, and inter-RNC hard handovers

RRC SETUP FAIL DUE TO FROZEN BTS

NetAct name: RRC_CONN_STP_FAIL_FROZBSDescription: The number of RRC setup failures caused by frozen BTS.

When the RNC decides to reject the RRC connection request, because the admission control entity blocks the radio link establishment, to ensure the setup of high priority calls. After this, the RNC sends an RRC: RRC CONNECTION REJECT message to the UE.

This counter is updated also in case of incoming SRNS relocations, inter-system handovers, and inter-RNC hard handovers

RRC CONN SETUP FAIL DUE TO RNTI ALLO FAIL

NetAct name: RRC_CONN_STP_FAIL_RNTI_ALLODescription: Number of RRC setup failures caused by RNTI allocation failure

When the RNC decides to reject the RRC connection request due to RNTI allocation failure caused by RRMU overload. After this, the RNC sends an RRC: RRC CONNECTION REJECT message to the UE

RRC SETUP FAIL DUE TO IUB AAL2 TRANS

NetAct name: RRC_CONN_STP_FAIL_IUB_AAL2Description: The number of RRC setup failures caused by Iub AAL2 transport resource shortage.

When the RNC decides to reject the RRC connection request due to Iub transport resource shortage between RNC and WBTS. After this the RNC sends an RRC: RRC CONNECTION REJECT message to the UEThis counter is updated also in case of inter-system handovers, and inter-RNC hard handover

RRC SETUP REJECT DUE TO EMERGENCY CALL REDIRECTION

NetAct name: RRC_CONN_STP_REJ_EMERG_CALLDescription: The number of RRC connections rejected due to emergency call redirection.

When the RNC redirects an emergency call to the GSM network by sending an RRC CONNECTION REJECT with redirection information to the UERRC CONN SETUP FAIL DUE TO ICSU OVERLOAD

NetAct name: RRC_CONN_STP_FAIL_ICSU_OVERLDescription: 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.
