As shown in fig. 3, the specific implementation flow includes:

in step S101, the terminal initiates a registration request message to the AMF, where the registration request message carries PC5 port awareness capability information (UE PC5 sensing capability info) of the terminal.

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

In step S102, the AMF obtains subscription information of the terminal from the UDR or the UDM, where the subscription information includes subscription information corresponding to the PC5 taste aware service of the terminal.

Optionally, when the AMF requests to obtain subscription information of the terminal from the UDR or the UDM, the AMF may carry the PC5 taste awareness as a key value, to indicate that the specific request is to obtain subscription information related to the PC5 taste awareness service of the terminal.

Step S103, the AMF judges whether the terminal has the corresponding perception authorization of the PC5 port or not based on the acquired subscription information corresponding to the PC5 port perception service of the terminal.

In the case of having the corresponding perceived authorization of the PC5 port, step S104 is performed.

Step S104, AMF selects PCF based on PC5 port perception capability information reported by terminal, and selects PCF supporting PC5 perception service.

It should be noted that, because step S102 and step S103 are optional steps, when the AMF does not execute step S102 and step S103, the AMF directly performs PCF selection according to the PC5 port awareness information reported by the terminal; when the AMF performs step S102 and step S103, the AMF performs PCF selection according to authorized PC5 port awareness capability information in the PC5 port awareness capability information reported by the terminal.

Further, an alternative implementation of the AMF to select the PCF is:

For example, a PCF is selected according to network format information of a perception signal of a PC5 subscribed by a terminal, wherein the PCF supports a policy making function corresponding to a PC5 perception service of the network format information.

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

Step 105, the AMF sends a request for establishing a perceived association to the PCF, for requesting the PCF to establish a perceived service policy association for the terminal.

In step S106, the PCF obtains subscription information of the terminal from the UDR or the UDM, where the subscription information includes subscription information corresponding to the PC5 taste aware service of the terminal.

Optionally, when the PCF requests to obtain subscription information of the terminal from the UDR or the UDM, the PCF may carry the PC5 taste awareness as a key value, to indicate that the specific request is to obtain subscription information related to the PC5 taste awareness service of the terminal.

Step S107, PCF judges whether the terminal has the corresponding perception authorization of PC5 port based on the obtained subscription information corresponding to the PC5 port perception service of the terminal.

In the case of having the corresponding perceived authorization of the PC5 port, step S108 is performed.

Here, step S106 and step S107 are optional steps, and in a preferred implementation, only one of step S102 and step S103 and step S106 and step S107 may be present, for example, step S106 and step S107 may not be performed after step S102 and step S103 are performed, or step S106 and step S107 may be performed when step S102 and step S103 are not performed.

Step S108, the PCF determines proper second strategy information for the terminal according to the perception association establishment request.

In step S109, the PCF sends the determined second policy information to the AMF.

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

In step S111, the 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 subsequent terminal and/or the access network device execute the PC5 aware service based on the related policy information.

It should be noted that, in at least one embodiment of the present application, the terminal reports the own PC5 port awareness capability information to the network, and the network side selects an appropriate policy network element for the terminal according to the capability information, so as to ensure that authorization information and policy information related to the PC5 port awareness service can be obtained, so that the terminal is authorized and can execute the PC5 awareness service according to an appropriate policy.
