context: This measurement provides the number of attempted outgoing inter-eNB handover preparations, the forwarded handovers for RN in DeNB are exclusive. CC. Transmission of the X2AP message HANDOVER REQUEST from the source eNB to the target eNB (see TS 36.423[ Evolved Universal Terrestrial Radio Access Network (E-UTRAN); X2 Application Protocol (X2AP) ] [10]), indicating the attempt of an outgoing inter-eNB handover preparation or on transmission of S1AP message HANDOVER REQUIRED to the MME (see TS 36.413[ Evolved Universal Terrestrial Radio Access Network (E-UTRAN); S1 Application Protocol (S1AP) ]  [9]), the forwarded X2AP message HANDOVER REQUEST and S1AP message HANDOVER REQUIRED for RN in DeNB are exclusive.

description: The X2 Application Protocol (X2AP) is a protocol used in the Evolved Universal Terrestrial Radio Access Network (E-UTRAN) for communication between eNodeBs. It is responsible for handling handover requests and preparations, as well as other mobility-related procedures.
explanation: X2AP is classified as a Protocol because it defines the rules and formats for data transmission between eNodeBs in the E-UTRAN, specifically for inter-eNB handover preparations and other related procedures. The provided context highlights its role in transmitting HANDOVER REQUEST messages between source and target eNBs.
