Method and apparatus for providing information for vehicle communication service

Abstract

A method for providing information for a vehicular wireless communication (V2X) service, performed by an access and mobility management function (AMF), is provided. The method includes receiving a registration request message from a user equipment (UE) including information indicating that the UE is a V2X terminal, selecting a policy control function (PCF) that supports the V2X service based on the registration request message, receiving V2X policy information from the selected PCF, and providing the V2X policy information to a base station.

Claims

1. A method for providing information for a vehicular wireless communication technology (V2X) service, performed by an access and mobility management function (AMF), the method comprising: receiving a registration request message from a user equipment (UE), where the registration request message includes information indicating that the UE is a V2X terminal; Send a request for subscription information to the User Data Management (UDM); receiving the subscription information from the UDM, wherein the subscription information includes authorization information indicating whether the UE is authorized to use the V2X service when the UE is capable of using the V2X service; Selecting a policy control function (PCF) that supports the V2X service based on the registration request message and the subscription information, where the selection of the PCF includes: transmitting a message requesting a network repository function NRF to discover a PCF supporting said V2X service; receiving information about the PCF from the NRF; and selecting the PCF discovered by the NRF; Obtaining V2X policy information from the selected PCF; and By providing the V2X policy information to the base station using the Next Generation Application Protocol (NGAP), The method further includes: in response to receiving updated V2X policy information from the selected PCF, providing the updated V2X policy information to the base station.

2. The method according to claim 1, The message requesting discovery of the PCF includes an indication of support for the V2X service.

3. The method according to claim 1, further comprising: In response to receiving the updated V2X policy information from the selected PCF, The updated V2X policy information is stored as part of the context information of the UE.

4. The method according to claim 1, The V2X policy information provided to the base station includes at least one of quality of service (QoS) parameter information or V2X authorization information, and The QoS parameter information includes at least one of the identification information of the V2X service or the PC5 QoS parameter.

5. A method for providing information for a vehicular wireless communication technology (V2X) service, performed by a policy control function (PCF), the method comprising: Establish policy association with the access and mobility management function (AMF); Generate V2X policy information; as well as Providing the generated V2X policy information to the AMF, The AMF selects a PCF as the PCF supporting the V2X service based on a registration request message of the user equipment UE and subscription information about whether the UE can use the V2X service. The AMF selects the PCF by: transmitting a message requesting a network repository function NRF to discover a PCF supporting said V2X service; receiving information about the PCF from the NRF; as well as Select the PCF found by the NRF, The subscription information includes authorization information, which indicates whether the UE is authorized to use the V2X service. The registration request message includes information indicating that the UE is a V2X terminal, and The method further comprises: Updating the V2X policy information; and Provide updated V2X policy information to the AMF.

6. The method according to claim 5, The V2X policy information includes at least one of quality of service (QoS) parameter information or V2X authorization information, and The QoS parameter information includes at least one of the identification information of the V2X service or the PC5 QoS parameter.

7. An access and mobility management function (AMF) for providing information for vehicular wireless communication technology (V2X) services, the AMF comprising: transceiver; and a processor electrically connected to the transceiver and configured to: receiving a registration request message from a user equipment (UE), wherein the registration request message includes information indicating that the UE is a V2X terminal; Send a request for subscription information to the User Data Management (UDM). receiving the subscription information from the UDM, wherein the subscription information includes authorization information indicating whether the UE is authorized to use the V2X service when the UE is capable of using the V2X service, Selecting a policy control function (PCF) that supports the V2X service based on the registration request message and the subscription information, wherein selecting the PCF includes: transmitting a message requesting the Network Repository Function NRF to discover the PCF supporting said V2X service, receiving information about the PCF from the NRF, and Select the PCF found by the NRF, Get V2X policy information from the selected PCF, Providing the V2X policy information to a base station by using the Next Generation Application Protocol (NGAP), and In response to receiving updated V2X policy information from the selected PCF, providing the updated V2X policy information to the base station.

8. A policy control function (PCF) for providing information for a vehicular wireless communication technology (V2X) service, the PCF comprising: transceiver; and a processor electrically connected to the transceiver and configured to: Establish policy association with the access and mobility management function AMF, Generate V2X policy information, Providing the generated V2X policy information to the AMF, updating the V2X policy information, and Providing updated V2X policy information to the AMF, The AMF selects a PCF as the PCF supporting the V2X service based on a registration request message of the user equipment UE and subscription information about whether the UE can use the V2X service. The AMF selects the PCF by: transmitting a message requesting a network repository function NRF to discover a PCF supporting said V2X service; receiving information about the PCF from the NRF; as well as Select the PCF found by the NRF, wherein the subscription information includes authorization information indicating whether the UE is authorized to use the V2X service, and The registration request message includes information indicating that the UE is a V2X terminal.
