Abstract

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).

First claim

1 . One or more non-transitory computer-readable storage media including computer executable instructions that, when executed by one or more processors, cause a mobility management entity (MME) to:
receive and process a first message from a user equipment (UE) to acquire information indicating that the UE supports vehicle-to-everything (V2X) communication; cause storage of the information indicating that the UE supports V2X communication in memory; receive subscription information from a first network entity; determine, based at least in part, on the subscription information that the UE is authorized to support V2X communication with a radio access technology (RAT); and transmit a second message to a second network entity, the second message to include an indication that the UE is authorized to support V2X communication with an RAT, information associated with one or more RATs, and a UE-PC5-Aggregate Maximum Bit Rate (AMBR).

2 . The one or more non-transitory computer-readable storage media of claim 1 , wherein the computer executable instructions, when executed by the one or more processors, further cause the MME to:
determine that the indication that the UE is authorized to support V2X communication with an RAT, the information associated with the one or more RATs, or the UE-PC5-AMBR is to be changed based, at least in part, on a change to the subscription information; and notify the second network entity, via a third message, of an updated indication that the UE is authorized to support V2X communication with an RAT, an updated information associated with the one or more RATs, or an updated UE-PC5-AMBR.

3 . The one or more non-transitory computer-readable storage media of claim 1 , wherein the first network entity comprises a Home Subscriber Server (HSS) and wherein the second network entity comprises an Evolved Universal Mobile Telecommunications System Terrestrial Radio Access Network (E-UTRAN).

4 . The one or more non-transitory computer-readable storage media of claim 1 , wherein the first message comprises a non-access stratum (NAS) message and wherein the second message comprises an S1 Application Protocol (S1AP) Initial Context Setup Request.

5 . The one or more non-transitory computer-readable storage media of claim 1 , wherein the computer executable instructions, when executed by the one or more processors, further cause the MME to:
perform the receive and process, the cause, the receive, the determine, and the transmit during or as part of an initial registration or attach procedure, a service request procedure, a tracking area update (TAU) procedure, a Xn-based handover procedure, or an S1-based handover procedure.

6 . The one or more non-transitory computer-readable storage media of claim 1 , wherein the indication that the UE is authorized to support V2X communication indicates that the UE is authorized to use V2X communication over a PC5 reference point, wherein the information associated with the one or more RATs indicates which RAT is authorized to be used for V2X communication over the PC5 reference point, and wherein the UE-PC5-AMBR assists with resource management of the UE's PC5 transmission in V2X communication.

7 . One or more non-transitory computer-readable storage media including computer executable instructions that, when executed by one or more processors, cause an access and mobility management function (AMF) to:
receive and process a first message from a user equipment (UE) to acquire information indicating that the UE supports vehicle-to-everything (V2X) communication; cause storage of the information indicating that the UE supports V2X communication in memory; receive subscription information from a first network entity; determine, based at least in part, on the subscription information that the UE is authorized to support V2X communication; and transmit a second message to a second network entity, the second message comprising an indication that the UE is authorized to support V2X communication, information associated with one or more RATs, and a UE-PC5-Aggregate Maximum Bit Rate (AMBR).

8 . The one or more non-transitory computer-readable storage media of claim 7 , wherein the computer executable instructions, when executed by the one or more processors, further cause the AMF to:
determine that the indication that the UE is authorized to support V2X communication with an RAT, the information associated with the one or more RATs, or the UE-PC5-AMBR is to be changed based, at least in part, on a change to the subscription information; and notify the second network entity, via a third message, of an updated indication that the UE is authorized to support V2X communication with an RAT, an updated information associated with the one or more RATs, or an updated UE-PC5-AMBR.

9 . The one or more non-transitory computer-readable storage media of claim 7 , wherein the first network entity comprises a Unified Data Management (UDM) and wherein the second network entity comprises a Next Generation Radio Access Network (NG RAN).

10 . The one or more non-transitory computer-readable storage media of claim 7 , wherein the first message comprises a Registration Request message and wherein the second message comprises an N2 message.

11 . The one or more non-transitory computer-readable storage media of claim 7 , wherein the computer executable instructions, when executed by the one or more processors, further cause the AMF to:
perform the receive and process, the cause, the receive, the determine, and the transmit as part of or during an initial registration or attach procedure, a service request procedure, a tracking area update (TAU) procedure, a Xn based handover procedure, or a S1 based handover procedure.

12 . The one or more non-transitory computer-readable storage media of claim 7 , wherein the indication that the UE is authorized to support V2X communication indicates that the UE is authorized to use V2X communication over a PC5 reference point, wherein the information associated with the one or more RATs indicates which RAT is authorized to be used for V2X communication over the PC5 reference point, and wherein the UE-PC5-AMBR assists with resource management of the UE's PC5 transmission in V2X communication.

13 . An apparatus to implement a mobility management entity (MME), the apparatus comprising:
interface circuitry to transmit and receive messages and processing circuitry, coupled with the interface circuitry, to:
receive, via the interface circuitry, and process a first message from a user equipment (UE) to acquire information indicating that the UE supports vehicle-to-everything (V2X) communication;
cause storage of the information indicating that the UE supports V2X communication in memory;
receive, via the interface circuitry, subscription information from a first network entity;
determine, based at least in part, on the subscription information that the UE is authorized to support V2X communication with a radio access technology (RAT); and
generate and transmit, via the interface circuitry, a second message to a second network entity, the second message comprising an indication that the UE is authorized to support V2X communication with an RAT, information associated with one or more RATs, and a UE-PC5-Aggregate Maximum Bit Rate (AMBR).

14 . The apparatus of claim 13 , wherein the processing circuitry is further to:
determine that the indication that the UE is authorized to support V2X communication with an RAT, the information associated with the one or more RATs, or the UE-PC5-AMBR is to be changed based, at least in part, on a change to the subscription informati
