In some embodiments, processing circuitry a communication network system may receive a registration request message from a UE indicating a V2X Radio Access Technology (RAT) configuration supported by the UE. The processing circuitry may retrieve authorization information from a Unified Data Management (UDM) repository and apply a policy control function (PCF) to the authorization information and the V2X RAT configuration specified by the UE to determine whether the UE has been authorized to communicate using the indicated V2X RAT configuration. In response to determining that the UE is authorized to communicate using the indicated V2X RAT configuration, the processing circuitry may transmit V2X service authorization parameters corresponding to the indicated V2X RAT configuration to a Radio Access Network (RAN) base station servicing the UE. ## Claims ### Claim 1 A method, comprising: receiving a registration request message from a user equipment (UE) indicating a vehicle-to-everything (V2X) Radio Access Technology (RAT) configuration supported by the UE, wherein the V2X RAT configuration comprises a V2X PC5 RAT capability, wherein PC5 indicates a capability for direct communication of the UE with another UE over a direct channel; applying an Access and Mobility Management Function (AMF) to the registration request message to identify the V2X PC5 RAT capability; retrieving authorization information corresponding to the UE from a Unified Data Management (UDM) repository; applying a policy control function (PCF) to the authorization information and the V2X RAT configuration specified by the UE to determine that the UE has been authorized to communicate using the indicated V2X RAT configuration; and in response to determining that the UE is authorized to communicate using the indicated V2X RAT configuration, transmitting V2X service authorization parameters corresponding to the indicated V2X RAT configuration to a Radio Access Network (RAN) base station servicing the UE. ### Claim 2 (depends on 1) The method of claim 1, wherein the V2X RAT configuration comprises a New Radio (NR) PC5 capability or a Long Term Evolution (LTE) PC5 capability and a New Radio (NR) PC5 capability. ### Claim 3 (depends on 1) The method of claim 1, wherein the registration request message is received in a UE policy container. ### Claim 4 (depends on 1) The method of claim 1, further comprising: transmitting the V2X service authorization parameters to the UE for V2X RAT communication. ### Claim 5 (depends on 1) The method of claim 1, wherein the registration request message is received in response to the UE moving from an Evolved Packet System (EPS) to a Fifth Generation System (5GS). ### Claim 6 (depends on 1) The method of claim 1, wherein the authorization information retrieved from the UDM repository includes roaming restriction data. ### Claim 7 (depends on 1) The method of claim 1, wherein the registration request message is a Non-Access Stratum (NAS) message. ### Claim 8 An apparatus, comprising: radio front end circuitry; and processing circuitry coupled to radio front end circuitry, wherein the processing circuitry is configured to: receive a registration request message from a user equipment (UE) indicating a vehicle-to-everything (V2X) Radio Access Technology (RAT) configuration supported by the UE, wherein the V2X RAT configuration comprises a V2X PC5 RAT capability, wherein PC5 indicates a capability for direct communication of the UE with another UE over a direct channel; apply an Access and Mobility Management Function (AMF) to the registration request message to identify the V2X PC5 RAT capability; retrieve authorization information corresponding to the UE from a Unified Data Management (UDM) repository; apply a policy control function (PCF) to the authorization information and the V2X RAT configuration specified by the UE to determine that the UE has been authorized to communicate using the indicated V2X RAT configuration; and in response to determining that the UE is authorized to communicate using the indicated V2X RAT configuration, transmit V2X service authorization parameters corresponding to the indicated V2X RAT configuration to a Radio Access Network (RAN) base station servicing the UE. ### Claim 9 (depends on 8) The apparatus of claim 8, wherein the V2X RAT configuration comprises a New Radio (NR) PC5 capability or a Long Term Evolution (LTE) PC5 capability and a New Radio (NR) PC5 capability. ### Claim 10 (depends on 8) The apparatus of claim 8, wherein the registration request message is received in a UE policy container. ### Claim 11 (depends on 8) The apparatus of claim 8, wherein processing circuitry is further configured to: transmit the V2X service authorization parameters to the UE for V2X RAT communication. ### Claim 12 (depends on 8) The apparatus of claim 8, wherein the registration request message is received in response to the UE moving from an Evolved Packet System (EPS) to a Fifth Generation System (5GS). ### Claim 13 (depends on 8) The apparatus of claim 8, wherein the authorization information retrieved from the UDM repository includes roaming restriction data. ### Claim 14 (depends on 8) The apparatus of claim 8, wherein the registration request message is a Non-Access Stratum (NAS) message. ### Claim 15 A method, comprising: receiving a vehicle-to-everything (V2X) policy provisioning request message from a user equipment (UE) indicating a V2X Radio Access Technology (RAT) configuration supported by the UE, wherein the V2X RAT configuration comprises a V2X PC5 RAT capability, wherein PC5 indicates a capability for direct communication of the UE with another UE over a direct channel; applying an Access and Mobility Management Function (AMF) to the registration request message to identify the V2X PC5 RAT capability; retrieving authorization information corresponding to the UE from a Unified Data Management (UDM) repository; applying a policy control function (PCF) to the authorization information and the V2X RAT configuration specified by the UE to determine that the UE has been authorized to communicate using the indicated V2X RAT configuration; and in response to determining that the UE is authorized to communicate using the indicated V2X RAT configuration, transmitting V2X service authorization parameters corresponding to the indicated V2X RAT configuration to the UE. ### Claim 16 (depends on 15) The method of claim 15, wherein the V2X RAT configuration comprises a New Radio (NR) PC5 capability or a Long Term Evolution (LTE) PC5 capability and a New Radio (NR) PC5 capability. ### Claim 17 (depends on 15) The method of claim 15, wherein the registration request message is received in a UE policy container. ### Claim 18 (depends on 15) The method of claim 15, wherein the V2X policy provisioning request message is received in response to the UE moving from an Evolved Packet System (EPS) to a Fifth Generation System (5GS). ### Claim 19 (depends on 15) The method of claim 15, wherein the authorization information retrieved from the UDM repository includes roaming restriction data. ### Claim 20 (depends on 15) The method of claim 15, wherein the V2X policy provisioning request message is a Non-Access Stratum (NAS) message.
