US Patent 11076318 Vehicle-to-Everything (V2X) communication authorization in Fifth Generation (5G) systems

One or more techniques of authorizing vehicle-to-everything (V2X) in a wireless network are set forth herein. In one example, during an initial registration procedure or an attach procedure, a UE includes its fifth generation (5G) V2X capability in a Non Access Stratum (NAS) message to a Mobility Management Entity (MME) or an Access and Mobility Management Function (AMF). The MME or the AMF stores this information and determines whether the UE is capable of or authorized to use V2X communication subscription information received from a Home Subscriber Server (HSS) or a Unified Data Management (UDM). If the UE is authorized, the MME or the AMF includes the V2X services authorized in a message from the MME or the AMF to an Evolved Universal Mobile Telecommunications System Terrestrial Radio Access Network (E-UTRAN) or a Next Generation Radio Access Network (NG RAN).
