METHOD AND APPARATUS FOR SELECTING EDGE APPLICATION SERVER, AND NETWORK ELEMENT DEVICE, USER EQUIPMENT AND STORAGE MEDIUM

WIPO Patent Application WO/2023/065088

A1

The present invention relates to a method and apparatus for selecting an edge application server, and a network device, a user equipment and a storage medium. The method comprises: a user equipment receiving first indication information, which is sent by an SMF, wherein the first indication information is used for indicating the priority of domain name system (DNS) information; and the user equipment making a DNS policy decision according to the first indication information, and sending a DNS query request to an EASDF, wherein the DNS query request is used by the EASDF to execute the discovery or selection of an edge application server (EAS). By means of the present invention, it is ensured that an EAS is always a preferred server, and a user equipment uses an EASDF to discover the optimal EAS, thereby genuinely improving the data transmission efficiency, and reducing a service delay; and there are fewer data transmission routing paths, thereby improving the service experience of a user.
