pmSumBestCs12Establish:Sum of all sample values recorded during a ROP for Erlang (voice) traffic. Incremented in the best cell in the active set. Not stepped for AMR-NB Multi-rate RAB. Condition: Values are read periodically from an internal level counter and added to this counter. The level counter maintains the current number of active speech 12.2 kbps RABs for which this cell is the best cell. The level counter is updated by RRC Connection Release, Inter-RAT Handover GSM to UTRAN, Inter-RAT Handover UTRAN to GSM, Inter-frequency Handover, RAB Establishment, RAB Release, Soft Handover, and Softer Handover, that is, whenever the radio link configuration is changed. It is also updated whenever the best cell changes without a change to the radio link configuration. Counter Type: ACC Scanner: Primary (initial state = Active) Sampling Period: 5 s Context: SRNC, DRNC if IurLink::srncPmReporting = ON in SRNC Counter is reset after measurement period: Yes
