Section: 4.3.1.1.3 Attempted outgoing intra-DeNB handover preparations from DeNB cell to RN per handover cause
Content: This measurement provides the number of attempted outgoing intra-DeNB handover preparations from DeNB cell to RN per handover cause; this measurement is only applicable to DeNB. CC. Transmission of the X2AP message HANDOVER REQUEST from the DeNB to RN (see TS 36.423[ Evolved Universal Terrestrial Radio Access Network (E-UTRAN); X2 Application Protocol (X2AP) ] [10]), indicating the attempt of an outgoing intra-DeNB handover preparation from DeNB cell to RN, the forwarded X2AP message HANDOVER REQUEST for the handover from another RN, eNB or DeNB to the RN is exclusive, the measurement is only incemented by one for one handover in case the X2AP message HANDOVER REQUEST are sent to multiple RNs. Each attempted outgoing intra-DeNB handover preparation from DeNB cell to RN 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]. The sum of all supported per cause measurements shall equal the total number of attempted outgoing intra-DeNB handover preparations from DeNB cell to RN. In case only a subset of per cause measurements is supported, a sum subcounter will be provided first. A single integer value.
