The present disclosure may be applied to intelligent services based on the 5G communication technology and the IoT-related technology, such as smart home, smart building, smart city, smart car, connected car, health care, digital education, smart retail, security and safety services. The method includes receiving, by a vehicle to everything (V2X) layer, first information on a V2X service from a V2X application layer and determining, by the V2X layer, range information corresponding to the first information on the V2X service based on a configuration. ## Claims ### Claim 1 A method performed by a terminal supporting a vehicle to everything (V2X) communication in a mobile communication system, the method comprising: receiving, from an access and mobility management function (AMF), policy information for the V2X communication; delivering, by a V2X application layer to a V2X layer, a V2X message, first information on a service type of the V2X message, and second information on a range required for the service type of the V2X message; and determining, by the V2X layer, range information corresponding to the service type of the V2X message, based on mapping information included in the policy information, wherein the range required for the service type of the V2X message and the service type of the V2X message are inputs for the mapping information, and the range information is an output for the mapping information. ### Claim 2 (depends on 1) The method of claim 1, further comprising delivering, by the V2X layer, the range information to an access stratum (AS) layer. ### Claim 3 (depends on 2) The method of claim 2, wherein the range information is used to determine, by the AS layer, a corresponding V2X message transmission. ### Claim 4 (depends on 2) The method of claim 2, further comprising: determining a radio access technology (RAT) type for a transmission of the V2X message; and identifying whether the range information is available for the RAT type, in case that the RAT type is determined to be a new radio (NR) RAT, wherein the range information is delivered to the AS layer, in case that the range information is available for the RAT type. ### Claim 5 (depends on 1) The method of claim 1, wherein the range information is in a unit of meters. ### Claim 6 (depends on 1) The method of claim 1, wherein the first information on the service type of the V2X message includes a provider service identifier (PSID) or an intelligent transport systems-application identifier (ITS-AID). ### Claim 7 (depends on 1) The method of claim 1, further comprising determining that the policy information for the V2X communication is invalid, in case that a validity timer in the policy information expires or there is no valid policy information for a current area. ### Claim 8 (depends on 7) The method of claim 7, further comprising: transmitting, to the AMF, a message for requesting updated policy information for the V2X communication; and receiving, from the AMF, the updated policy information for the V2X communication as a response to the message. ### Claim 9 A terminal supporting a vehicle to everything (V2X) communication in a mobile communication system, the terminal comprising: a transceiver; and a controller coupled with the transceiver and configured to: receive, from an access and mobility management function (AMF) via the transceiver, policy information for the V2X communication, deliver, by a V2X application layer to a V2X layer, a V2X message, first information on a service type of the V2X message, and second information on a range required for the service type of the V2X message, and determine, by the V2X layer, range information corresponding to the service type of the V2X message, based on mapping information included in the policy information, wherein the range required for the service type of the V2X message and the service type of the V2X message are inputs for the mapping information, and the range information is an output for the mapping information. ### Claim 10 (depends on 9) The terminal of claim 9, wherein the controller is further configured to deliver, by the V2X layer, the range information to an access stratum (AS) layer. ### Claim 11 (depends on 10) The terminal of claim 10, wherein the range information is used to determine, by the AS layer, a corresponding V2X message transmission. ### Claim 12 (depends on 10) The terminal of claim 10, wherein the controller is further configured to: determine a radio access technology (RAT) type for a transmission of the V2X message, and identify whether the range information is available for the RAT type, in case that the RAT type is determined to be a new radio (NR) RAT, wherein the range information is delivered to the AS layer, in case that the range information is available for the RAT type. ### Claim 13 (depends on 9) The terminal of claim 9, wherein the range information is in a unit of meters. ### Claim 14 (depends on 9) The terminal of claim 9, wherein the first information on the service type of the V2X message includes a provider service identifier (PSID) or an intelligent transport systems-application identifier (ITS-AID). ### Claim 15 (depends on 9) The terminal of claim 9, wherein the controller is further configured to determine that the policy information for the V2X communication is invalid, in case that a validity timer in the policy information expires or there is no valid policy information for a current area. ### Claim 16 (depends on 15) The terminal of claim 15, wherein the controller is further configured to: transmit, to the AMF via the transceiver, a message for requesting updated policy information for the V2X communication, and receive, from the AMF via the transceiver, the updated policy information for the V2X communication as a response to the message.
