Taking the first core network device as AMF and the second core network device as PCF as an example, the specific implementation process of the embodiment of the present application is described in detail as follows.

As shown in Figure 3, the specific implementation process includes:

Step S101, the terminal initiates a registration request message to AMF, and the registration request message carries the terminal's PC5 port sensing capability information (UE PC5 sensing capability info).

Optionally, the PC5 port perception capability information may be further included in the perception capability information of the terminal carried in the registration request message.

Step S102, AMF obtains the contract information of the terminal from UDR or UDM, and the contract information includes the contract information corresponding to the PC5 port perception service of the terminal.

Optionally, when AMF requests UDR or UDM to obtain the contract information of the terminal, it can carry PC5 port perception as a key value to indicate that the specific request is to obtain the contract information related to the PC5 port perception service of the terminal.

Step S103, AMF determines whether the terminal has the corresponding PC5 port perception authorization based on the acquired contract information corresponding to the PC5 port perception service of the terminal.

If the corresponding PC5 port perception authorization is available, step S104 is executed.

Step S104: AMF selects a PCF based on the PC5 port perception capability information reported by the terminal, and selects a PCF that supports the PC5 perception service.

It should be noted here that since step S102 and step S103 are optional steps, when AMF does not execute step S102 and step S103, AMF directly selects PCF based on the PC5 port perception capability information reported by the terminal; when AMF executes step S102 and step S103, AMF selects PCF based on the authorized PC5 port perception capability information in the PC5 port perception capability information reported by the terminal.

Furthermore, an optional implementation of AMF selecting PCF is:

For example, according to the network standard information of the PC5 port sensing signal signed by the terminal, a PCF is selected, wherein the PCF supports policy formulation functions corresponding to the PC5 perception services of the network standard information.

For another example, according to the service identification information of the PC5 port perception service subscribed by the terminal, a PCF is selected, wherein the PCF supports a policy formulation function corresponding to the perception service identified by the service identification information.

Step S105, AMF sends a perception association establishment request to PCF, requesting PCF to establish a perception service policy association for the terminal.

Step S106: The PCF obtains the contract information of the terminal from the UDR or UDM, where the contract information includes the contract information corresponding to the PC5 port perception service of the terminal.

Optionally, when PCF requests UDR or UDM to obtain the contract information of the terminal, it can carry PC5 port perception as a key value to indicate that the specific request is to obtain the contract information related to the PC5 port perception service of the terminal.

Step S107: The PCF determines whether the terminal has the corresponding PC5 port perception authorization based on the acquired contract information corresponding to the PC5 port perception service of the terminal.

If the corresponding PC5 port perception authorization is available, step S108 is executed.

It should be noted here that step S106 and step S107 are optional steps. In the preferred implementation, only one of step S102 and step S103 and step S106 and step S107 can exist. For example, after executing step S102 and step S103, step S106 and step S107 do not need to be executed, or, when step S102 and step S103 are not executed, step S106 and step S107 can be executed.

Step S108: The PCF determines appropriate second policy information for the terminal according to the perception association establishment request.

Step S109: PCF sends the determined second policy information to AMF.

Step S110, the AMF determines the first policy information based on the second policy information;

Step S111, AMF sends part or all of the first policy information to the terminal and/or the access network device corresponding to the terminal, so that the terminal and/or the access network device can subsequently perform PC5 perception services based on the relevant policy information.

It should be noted that in at least one embodiment of the present application, the terminal reports its own PC5 port perception capability information to the network, and the network side selects a suitable policy network element for the terminal based on the capability information, thereby ensuring that the authorization information and policy information related to the PC5 port perception service can be obtained, so that the terminal is authorized and can execute the PC5 perception service according to the appropriate strategy.
