Abstract: The present disclosure relates to application server discovery methods and apparatuses. In one example method, a configuration server receives a first request message, where the first request message is used to request to discover an enabler server, and the enabler server is configured to serve a plurality of terminal devices. The configuration server determines a target enabler server based on information about a terminal device group, where the terminal device group includes the plurality of terminal devices. The configuration server sends a first response message, where the first response message includes information about the target enabler server. An application server is discovered with reference to the information about the terminal device group.

Abstract: This application provides a communication method and apparatus. The method includes: An EASDF receives an identifier of a target service from a first terminal; the EASDF obtains an address of a same target application server that needs to be accessed by a plurality of terminals including the first terminal to access the target service; and the EASDF sends the address of the target application server to the first terminal. Hence, the EASDF obtains, for a same target service, identifiers (referred to as a UE list) of a plurality of UEs that need to access a same EAS. After UE (for example, UE #1) in the UE list performs an EAS discovery procedure for the target service, the EASDF obtains an address of the target EAS, and sends, to another UE in the list, an address of the target EAS that is the same as an address of the UE #1.
