Before describing the method for determining the service transmission policy in the embodiment of the present application in detail, an implementation environment and an application scenario in the embodiment of the present application are described first.

First, an application scenario of the embodiment of the present application is described.

The method for determining the service transmission strategy is applied to a scene that a terminal interacts with an edge server (such as a scheduling server (a server corresponding to a scheduling platform), a DNS server and a CDN server) through a UPF network element. In the related art, when a terminal interacts with an edge server through a UPF network element, address information of the edge server needs to be stored in the terminal. And then, the terminal can interact with the edge server according to the address information.

Illustratively, the terminal stores address information a and address information B, where the address information a is address information of the DNS server, and the address information B is address information of the scheduling platform. And the terminal interacts with the DNS through the UPF network element according to the address information A, and interacts with the dispatching platform through the UPF network element according to the address information B.

With reference to fig. 1, the following describes an interaction process between a terminal and a DNS server, a scheduling platform, and a CDN server through a UPF network element. The UPF network element is used for forwarding and identifying the service data according to the strategy. The DNS server is used to query an Internet Protocol (IP) address of a scheduling platform corresponding to a domain name. The scheduling platform is used for inquiring the IP address of the CDN server. The CDN server is used for distributing the service content.

The terminal stores address information of a first server, and the first server is a DNS server. And the terminal accesses the first server through the target network element according to the address information of the first server and acquires the address information of the dispatching platform, wherein the target network element is a UPF network element. And then the terminal accesses the scheduling platform through the target network element according to the address information of the scheduling platform and acquires the address information of a second server, wherein the second server is a CDN server. And then, the terminal interacts with the second server through the target network element according to the address information of the second server to acquire the service data.

However, in the current technical solution, when the location of the terminal changes, the distance between the terminal and the edge server may also change, which may increase the signal transmission time between the terminal and the edge server, thereby reducing the transmission efficiency of the service data between the terminal and the edge server.

In order to solve the foregoing problem, an embodiment of the present application provides a method for determining a service transmission policy, where an SMF network element may obtain third address information and first location information, where the third address information is address information of a second DNS server stored in a terminal, and the first location information is used to indicate an area where the terminal is located. And then, the SMF network element determines target area information according to the third address information, wherein the target area information is service area information of the second DNS server. If the area corresponding to the first location information is not located in the area corresponding to the target area information, the SMF network element determines a first DNS server from a plurality of stored preset DNS servers according to the first location information, and determines fourth address information, wherein the area corresponding to the first location information is located in the area corresponding to the service area information of the first DNS server, and the fourth address information is the address information of the first DNS server. And then, the SMF network element sends a first message to the terminal, wherein the first message is used for indicating the terminal to update the stored address information of the DNS server into fourth address information. That is, the SMF network element may instruct the terminal to store address information of a DNS server located in the same area as the terminal. Therefore, the distance between the terminal and the DNS server can be reduced, the signal transmission time between the terminal and the DNS server is shortened, and the determination efficiency of the service transmission strategy between the terminal and the DNS server is improved.

For example, the server acquires information (e.g., factory information, network device setting information) of the network device. And, the server may process information of the network device. And, the server may also store information of the network devices.

S303, the session management function network element determines whether the area corresponding to the first location information is located in the area corresponding to the target area information.

Illustratively, the first location information is cell a and the target area information is cell B. And if the cell B comprises the cell A, the SMF network element determines that the cell A is positioned in the cell B. And if the cell B does not comprise the cell A, the SMF network element determines that the cell A is not positioned in the cell B.

In some embodiments, if the area corresponding to the first location information is not located in the area corresponding to the target area information, the SMF network element performs S304.

S304, the session management function network element determines a first domain name system server from a plurality of preset domain name system servers according to the first position information and the service area information of each preset domain name system server.

Illustratively, the plurality of preset DNS servers includes: server a, server B, and server C. The service area information of the server a is the cell a, the service area information of the server B is the cell B, and the service area information of the server C is the cell C. If the first location information is cell D and cell B includes cell D, the SMF network element determines that server B is the first DNS server.
