Section: 4.3.1.2.2 Attempted outgoing inter-eNB handover executions per handover cause
Content: This measurement provides the number of attempted outgoing inter-eNB handovers per handover cause. CC. Transmission of the RRC ConnectionReconfiguration message to UE triggering the handover from the source eNB to the target eNB, indicatingthe attempt of an outgoing inter-eNB handover (see TS 36.331[ Evolved Universal Terrestrial Radio Access (E-UTRA); Radio Resource Control (RRC); Protocol specification ]  [8]). The sum of all supported per cause measurements shall equal the total number of outgoing inter-eNB handover event Each RRCConnectionReconfiguration message transimtted is added to the relevant per handover cause measurement, the possible causes are included in TS 36.413[ Evolved Universal Terrestrial Radio Access Network (E-UTRAN); S1 Application Protocol (S1AP) ]  [9]. In case only a subset of per cause measurements is supported, a sum subcounter will be provided first. 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.
