Abstract

Provided are a communication method and system that combine the 5G communication system and the IoT technology to support a higher data rate after the 4G system. Based on the 5G communication technology and IoT technology, the disclosure can be applied to various intelligent services (e.g., smart home, smart building, smart city, smart or connected, car, healthcare, digital education, retail business, and security and safety service). The disclosure relates to a method and apparatus for terminating a cellular network connection to a terminal without authentication. The disclosure relates to a method and system for providing a vehicle communication service in the 3GPP system.

First claim

What is claimed is:

1. A method performed by a terminal in a wireless communication system, the method comprising:
receiving, from an access and mobility management function (AMF), a user equipment (UE) configuration update message including mapping information received from a policy control function (PCF) based on a UE policy update being triggered by the PCF, the mapping information for mapping between at least one vehicle to everything (V2X) service type and at least one radio access technology (RAT) type;
selecting at least one RAT type corresponding to a V2X message to be transmitted, based on the mapping information; and
transmitting the V2X message using the selected at least one RAT type,
wherein the selecting the at least one RAT type is performed by a V2X layer of the terminal.

2. The method of claim 1 , wherein the transmitting the V2X message comprises:
transmitting the V2X message using at least one of a long term evolution (LTE) RAT or a next generation (NR) RAT, in case that the selected at least one RAT type corresponding to the V2X message is the LTE RAT and the NR RAT.

3. The method of claim 1 , wherein the receiving the mapping information comprises:
transmitting, to the AMF, a request message; and
receiving, from the AMF, a response message including the mapping information received from the PCF stored in a user data repository (UDR), as a response to the request message.

4. A method performed by an access and mobility management function (AMF) in a wireless communication system, the method comprising:
receiving, from a policy control function (PCF), a user equipment (UE) configuration update message including mapping information based on a UE policy update being triggered by the PCF, the mapping information for mapping between at least one vehicle to everything (V2X) service type and at least one radio access technology (RAT) type; and
transmitting, to a terminal, the mapping information for the terminal to select at least one RAT type corresponding to a V2X message to be transmitted and to transmit the V2X message using the selected at least one RAT type,
wherein the at least one RAT type is selected by a V2X layer of the terminal.

5. The method of claim 4 , wherein the receiving the mapping information comprises:
receiving, from the terminal, a request message;
transmitting, to the PCF, a policy request message; and
receiving, from the PCF, a policy response message including the mapping information received from a user data repository (UDR),
wherein the transmitting the mapping information comprises transmitting, to the terminal, a response message including the mapping information.

6. The method of claim 4 ,
wherein the transmitting the mapping information comprises transmitting, to the terminal, the UE configuration update message including the mapping information.

7. A terminal in a wireless communication system, the terminal comprising:
a transceiver; and
a controller configured to:
receive, from an access and mobility management function (AMF) via the transceiver, a user equipment (UE) configuration update message including mapping information received from a policy control function (PCF) based on a UE policy update being triggered by the PCF, the mapping information for mapping between at least one vehicle to everything (V2X) service type and at least one radio access technology (RAT) type,
select at least one RAT type corresponding to a V2X message to be transmitted, based on the mapping information, and
transmit, via the transceiver, the V2X message using the selected at least one RAT type,
wherein the at least one RAT type is selected by a V2X layer of the terminal.

8. The terminal of claim 7 , wherein the controller is configured to transmit, via the transceiver, the V2X message using at least one of a long term evolution (LTE) RAT or a next generation (NR) RAT, in case that the selected at least one RAT type corresponding to the V2X message is the LTE RAT and the NR RAT.

9. The terminal of claim 7 , wherein the controller is configured to:
transmit, to the AMF via the transceiver, a request message, and receive, from the AMF, a response message including the mapping information received from the PCF stored in a user data repository (UDR), as a response to the request message.

10. An access and mobility management function (AMF) in a wireless communication system, the AMF comprising:
a transceiver; and
a controller configured to:
receive, from a policy control function (PCF) via the transceiver, a user equipment (UE) configuration update message including mapping information based on a UE policy update being triggered by the PCF, the mapping information for mapping between at least one vehicle to everything (V2X) service type and at least one radio access technology (RAT) type, and
transmit, to a terminal via the transceiver, the mapping information for the terminal to select at least one RAT type corresponding to a V2X message to be transmitted and to transmit the V2X message using the selected at least one RAT type,
wherein the at least one RAT type is selected by a V2X layer of the terminal.

11. The AMF of claim 10 , wherein the controller is configured to receive, from the terminal via the transceiver, a request message, transmit, to the PCF, a policy request message, and receive, from the PCF, a policy response message including the mapping information received from a user data repository (UDR), and
wherein the controller is configured to transmit, to the terminal via the transceiver, a response message including the mapping information.

12. The AMF of claim 10 ,
wherein the controller is configured to transmit, to the terminal via the transceiver, the UE configuration update message including the mapping information.
