ering data to the UE(s) in a target area using a unicast and/or eMBMS delivery mechanism as well as mapping of geographic location information to the appropriate target eMBMS service area identities for the broadcast. It is further responsible for mapping from geographic location information to the appropriate [target] E-UTRAN cell global identifier (ECGI), which is used to globally identify the cells. The Broadcast multicast service center is an evolved multimedia broadcast multicast service network entity located in the core network and is responsible for authorization and authentication of content providers, charging, and overall configuration of the data flow through the core network. Vehicle-to-Everything (V2X) Communications 805 V2X application server handles the mapping from UE provided ECGI to appropriate tar- get eMBMS service area identities for the broadcast; provides the appropriate ECGI(s) and/or eMBMS service area identities to BM-SC, which is preconfigured with the local eMBMS information (e.g., Internet protocol (IP) multicast address, multicast source, com- mon tunnel endpoint identifier); and is preconfigured with the local eMBMS IP address and port number for the user plane. The V2X application server is also in charge of send- ing local eMBMS information to the BM-SC; requesting BM-SC for allocation/de-alloca- tion of a set of temporary mobile group identities; requesting BM-SC for activating/ deactivating/modifying the eMBMS bearer; providing the V2X USDs SO that the UE can receive eMBMS-based V2X traffic from V2X control function; providing the parameters for V2X communications over PC5 reference point to V2X control function; or providing the parameters for V2X communications over PC5 reference point to UE [2]. The reference points or network interfaces shown in Fig. 7.7 can be further described as fol- lows [2]: V1: This reference point is between the V2X application in the UE and in the V2X application server, and it is not defined in 3GPP specifications. V2: This reference point is betwe
