Fig. 6 is a process diagram of a PCF network element performing service control policy subscription in the embodiment of the present disclosure. In order to more clearly illustrate the private network subscription process after adding the enterprise service policy, five terminal devices are taken as an example in fig. 6, because the private network identifier and the service identifier are added to the user subscription template of the UDM network element in the embodiment of the present disclosure, a corresponding relationship table is preset in the private network enterprise subscription template of the PCF network element, the SMF network element sends a session policy control creation request carrying the private network identifier and the service identifier to the PCF network element, the PCF network element searches for a corresponding service control policy according to the private network identifier and the service identifier, the PCF network element does not need to perform data configuration of the service control policy for each terminal device user, and only needs to query the corresponding service control policy according to the private network identifier and the service identifier, and the corresponding service control policies are the same for two terminal devices under the condition that the private network identifier and the service identifier are the same; if the private network identifiers of the two terminal devices are the same and the service identifiers are different, the corresponding service control strategies are different; if the private network identifiers of the two terminal devices are different and the service identifiers are the same, the corresponding service control strategies are different; if the private network identifiers of the two terminal devices are different and the service identifiers are different, the corresponding service control strategies are different.

When the private network identifications of the two terminal devices are the same and the service identifications are different, for example, the private networks corresponding to the first terminal device and the fifth terminal device are both private network a, the service packages corresponding to the first terminal device and the fifth terminal device are service package a and service package b respectively, and the service identifications corresponding to the first terminal device and the fifth terminal device are different, so that the service control strategies corresponding to the first terminal device and the fifth terminal device are also different, and the service control strategies corresponding to the first terminal device and the fifth terminal device are service control strategy a and service control strategy d respectively; for example, the first terminal device and the second terminal device, the private networks corresponding to the first terminal device and the second terminal device are both private network a, the first terminal device corresponds to service package a, the second terminal device corresponds to two service packages, the two service packages are service package a and service package b, the service identifiers corresponding to the first terminal device and the second terminal device are different, and therefore, the service control policies of the first terminal device and the second terminal device are also different.

When the private network identifiers of the two terminal devices are different and the service identifiers are the same, for example, the first terminal device and the fourth terminal device, the private networks corresponding to the first terminal device and the fourth terminal device are respectively a private network a and a private network b, the private network identifiers corresponding to the first terminal device and the fourth terminal device are respectively a private network identifier a and a private network identifier b, the service packages corresponding to the first terminal device and the fourth terminal device are both a service package a, the service identifiers corresponding to the first terminal device and the fourth terminal device are different, therefore, the service control strategies corresponding to the first terminal device and the fourth terminal device are also different, and the service control strategies corresponding to the first terminal device and the fourth terminal device are respectively a service control strategy a and a service control strategy c.

When the private network identifiers of the two terminal devices are different and the service identifiers are different, for example, the private network identifiers of the second terminal device and the fifth terminal device are respectively a private network identifier a and a private network identifier b, the service identifier of the second terminal device is a combination of the service identifier a and the service identifier b, the service identifier of the fifth terminal device is a service identifier b, the service identifiers of the second terminal device and the fifth terminal device are different, and the corresponding service control policies are also different.

When the requirements of two terminal devices are the same, the private network identifiers and the service identifiers of the two terminal devices are also the same, for example, the first terminal device and the third terminal device in fig. 6, the private network required by the first terminal device and the third terminal device is private network a, so the private network identifiers corresponding to the first terminal device and the third terminal device are both private network identifiers a, the service packages required by the first terminal device and the third terminal device are both service packages a, so the service identifiers corresponding to the first terminal device and the third terminal device are both service identifiers a, the private network service identifier information corresponding to the first terminal device and the third terminal device is the same, the PCF network element queries the associated private network identifier a and service identifier a from the private network enterprise subscription template according to the private network identifier a and service identifier a reported by the SMF network element, and invokes the corresponding service control policy a, therefore, the calling of the service control strategy a is completed, the terminal equipment with the same private network service identification information can call the same service control strategy without performing data configuration of the service control strategy for each terminal equipment, fig. 6 lists the conditions of different private network service identification information of five terminal equipments for explaining the identification condition of the private network service identification information, the number of the terminal equipments is usually tens of thousands to hundreds of thousands in the actual signing process of the enterprise terminal equipment, the required types corresponding to the terminal equipments are very few, 2-5 types are often used, that is, the types of the private network service identification information corresponding to the terminal equipments are 2-5 types, the corresponding service control strategies are 2-5, and the terminal equipment with the same private network service identification information can call the corresponding service control strategy, the data configuration of the service control strategy is not needed for the terminal equipment, and the problem that the 2B service strategy rule of the PCF network element is large in scale because each terminal equipment of an enterprise needs to customize a service control strategy is solved.
