1 Total RRC Connection Requests (RNC)This KPI means the number of RRC Connection Request messages from UEs to the RNC. When a UE attempts to access the network, it sends an RRC Connection Request message to the RNC possibly many times to increase the connection probability. Each time the RNC receives the RRC Connection Request message, the measurement is triggered.

2 RRC Connection Success (RNC)This KPI means: the ratio of number of RRC connection setup complete / Total RRC Connection Requests *100%

Number of RRC connection setup complete means the number RNC receives from the UEs according to different channels of RRC connection setups.3 Total Speech Attempts (RNC)This item means: the number of CS RABs requested to establish for conversational services

4 Speech Setup Success (RNC)This KPI means: RRC Connection Success*(Number of CS RABs successfully established for conversational services / Total Speech Attempts)*100%

5 Speech Dropped Calls (RNC)This KPI means: Number of released CS AMR service RABs triggered by RNC/ Number of CS RABs successfully established for conversational services * 100%6 CS64 Attempts (RNC)This KPI means: Number of CS RABs requested to establish for Video Phone services

7 CS64 Setup Success (RNC)This KPI means: RRC Connection Success*(Number of CS RABs successfully established for Video Phone services / CS64 Attempts)*100%

8 CS64 Dropped Calls (RNC)This KPI means: Number of released Video Phone service RABs triggered by RNC/ Number of CS RABs successfully established for Video Phone services * 100%

9 PS Attempts (RNC)This KPI means: Number of the PS RABs requested to establish for conversational services+ Number of the PS RABs requested to establish for streaming services+ Number of the PS RABs requested to establish for interactive services +Number of the PS RABs requested to establish for background services

10 PS RAB Setup Success (RNC)This KPI means: (Number of PS RABs successfully established for conversational services (no queuing)+ Number of PS RABs successfully established for streaming services (no queuing)+ Number of PS RABs successfully established for interactive services (no queuing)+ Number of PS RABs successfully established for background services (no queuing)+ Number of PS RABs successfully established for conversational services (with queuing)+ Number of PS RABs successfully established for streaming services (with queuing)+ Numbers of PS RABs successfully established for interactive services (with queuing)+ Numbers of PS RABs successfully established for background services (with queuing) )/ PS Attempts * 100%

11 PS Service Setup Success (RNC)This KPI means: RRC Connection Success* PS RAB Setup Success12 PS Dropped Calls (RNC)This KPI means: (Number of released PS RABs triggered by the RNC due to RF failure + Number of abnormally released PS RABs)/(Number of PS RABs successfully established for conversational services (no queuing)+ Number of PS RABs successfully established for streaming services (no queuing)+ Number of PS RABs successfully established for interactive services (no queuing)+ Number of PS RABs successfully established for background services (no queuing)+ Number of PS RABs successfully established for conversational services (with queuing)+ Number of PS RABs successfully established for streaming services (with queuing)+ Numbers of PS RABs successfully established for interactive services (with queuing)+ Numbers of PS RABs successfully established for background services (with queuing) * 100%13 PS DL Traffic (RNC)This KPI means: the downlink traffic of all the R99 services in the PS domain within the RNC

14 PS UL Traffic (RNC)This KPI means: the uplink traffic of all the R99 services in the PS domain within the RNC

15 HSDPA Traffic (RNC)This KPI means: the downlink traffic of all the HSDPA services in the PS domain within the RNC
