4.15.0 Introduction

The three measurement types defined in subclause 4.15…n for Intra-cell DCA are subject to the "2 out of 3 approach".

4.15.1 Attempted intra-cell DCA

  1. This measurement provides the number of attempted intra-cell DCA per cell. This measurement is only valid for TDD mode.
  2. CC
  3. Transmission of a RRC message PHYSICAL CHANNEL RECONFIGURATION, RADIO BEARER SETUP, RADIO BEARER RECONFIGURATION, RADIO BEARER RELEASE, or TRANSPORT CHANNEL RECONFIGURATION from the source RNC to the UE, indicating the attempt of an intra-cell DCA (see TS 25.331 [4]).
  4. A single integer value
  5. DCA.AttIntraCell.
  6. UtranCellTDDLcr
    UtranCellTDDHcr
  7. Valid for circuit switched and packet switched traffic
  8. UMTS

4.15.2 Successful intra-cell DCA

  1. This measurement provides the number of successful intra-cell DCA per cell. This measurement is only valid for TDD mode.
  2. CC
  3. Receipt of a RRC message PHYSICAL CHANNEL RECONFIGURATION COMPLETE, RADIO BEARER SETUP COMPLETE, RADIO BEARER RECONFIGURATION COMPLETE, RADIO BEARER RELEASE COMPLETE, or TRANSPORT CHANNEL RECONFIGURATION COMPLETE sent from the UE to the source RNC, indicating a successful intra-cell DCA (see TS 25.331 [4]).
  4. A single integer value
  5. DCA.SuccIntraCell.
  6. UtranCellTDDLcr
    UtranCellTDDHcr
  7. Valid for circuit switched and packet switched traffic
  8. UMTS

4.15.3 Failed intra-cell DCA

  1. This measurement provides the number of failed intra-cell DCA per cell per cause. This measurement is only valid for TDD mode.
  2. CC
  3. Receipt of a RRC message PHYSICAL CHANNEL RECONFIGURATION FAILURE, RADIO BEARER SETUP FAILURE, RADIO BEARER RECONFIGURATION FAILURE, RADIO BEARER RELEASE FAILURE, or TRANSPORT CHANNEL RECONFIGURATION FAILURE sent from the UE to the source RNC, indicating a failed intra-cell DCA. Failure causes are defined within TS 25.331 [4].

    Each expected RRC message PHYSICAL CHANNEL RECONFIGURATION COMPLETE, RADIO BEARER SETUP COMPLETE, RADIO BEARER RECONFIGURATION COMPLETE, RADIO BEARER RELEASE COMPLETE, TRANSPORT CHANNEL RECONFIGURATION COMPLETE, PHYSICAL CHANNEL RECONFIGURATION FAILURE, RADIO BEARER SETUP FAILURE, RADIO BEARER RECONFIGURATION FAILURE, RADIO BEARER RELEASE FAILURE, or TRANSPORT CHANNEL RECONFIGURATION FAILURE not received by the source RNC is added to the measurement cause ‘No Reply’ (not specified in TS 25.331 [4]).

    The sum of all supported per cause measurements shall equal the total number of failed events. 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 supported plus a possible sum value identified by the .sum suffix.
  5. The measurement name has the form DCA.FailIntraCell.Cause
    where Cause identifies the failure cause.
    The cause ‘No Reply’ is identified by the .NoReply suffix.
  6. UtranCellTDDLcr
    UtranCellTDDHcr
  7. Valid for circuit switched and packet switched traffic
  8. UMTS
