RRC Setup Success Ratio (service) The RRC setup procedure is trigged by different reasons, which can be divided into two classes, the related service and other reasons. This KPI can be used to evaluate the RRC setup success ratio, which only includes the service causes in one RNC or a cluster. Such as Originating Conversational Call, Terminating Streaming Call and so on.

The process of RRC connection setup includes the following steps:

•The UE sends the RRC Connection Request message through the RACH. •The RNC sends the RRC Connection Setup message through the FACH. •If the RRC is established on the DCH, the UE sends the RRC Connection Setup CMP message through the uplink dedicated channel after the downlink dedicated channel is set up and synchronized. •If the RRC is established on the CCH, the UE directly sends the RRC Connection Setup CMP message through the RACH. •The RRC connection setup fails in the following scenarios: •The UE sends the RRC Connection Request message, but the RNC does not receive the message. •The RNC receives the RRC Connection Request message sent by the UE and delivers the RRC Connection Setup message, but the UE does not receive the RRC Connection Setup message. •The RNC receives the RRC Connection Request message sent by the UE, and delivers the RRC Connection Reject message. •The UE receives the RRC Connection Setup message, but does not send the RRC Setup Complete message. •The UE sends the RRC Setup Complete message, but the RNC does not receive the message.
