Section: 4.3.1.3.1 Attempted outgoing handovers per handover cause
Content: This measurement provides the number of attempted outgoing handovers per handover cause and LTE target cell specific. CC. Transmission of the RRCConnection reconfiguration message to UE triggering the intra-RAT handover (see TS 36.331[ Evolved Universal Terrestrial Radio Access (E-UTRA); Radio Resource Control (RRC); Protocol specification ]  [8]). 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 of CA, this attempted handover is only added to the neighbour cell relation from the source EUTRAN cell, through which the RRCConnectionReconfiguration message is sent to the UE, to the target EUTRAN cell appointed in the “MobilityControlInfo” IE of the RRCConnectionReconfiguration message. The sum of all supported per cause measurements shall equal the total number of outgoing handover events. 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.
