Content: This measurement provides the number of successful outgoing inter-eNB handovers per handover cause, the forwarded handovers for RN in DeNB are exclusive. CC. Receipt at the source eNB of UE CONTEXT RELEASE [10] over the X2 from the target eNB following a successful handover, or if handover is performed via S1, receipt of UE CONTEXT RELEASE COMMAND [9] at the source eNB following a successful handover, the forwarded X2AP UE CONTEXT RELEASE message and S1AP UE CONTEXT RELEASE COMMAND message for RN in DeNB are exclusive.

The sum of all supported per cause measurements shall equal the total number of outgoing inter-eNB 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. HO.InterEnbOutSucc.Cause where Cause identifies the cause for handover.
