4.6.1 Attempted RRC connection releases on DCCH

  1. This measurement provides the number of RRC connection release attempts per release cause sent from UTRAN to the UE on the DCCH.
  2. CC
  3. Transmission of an RRC CONNECTION RELEASE message by the RNC to the UE on DCCH. Each RRC Connection Release message sent on DCCH is added to the relevant per cause measurement. The possible causes are included in TS 25.331 [4]. The sum of all supported per cause measurements shall equal the total number of RRC Connection Release attempts on DCCH. In case only a subset of per cause measurements is supported, a sum subcounter will be provided first.
  4. Each measurement is an integer value. The number of measurements is equal to the number of causes plus a possible sum value identified by the .sum suffix.
  5. The measurement name has the form RRC.AttConnRelDCCH.Cause
    where Cause identifies the Release Cause.
