Abstract: A communication method and a related apparatus are provided. The method includes: after determining that the cell accessed by the terminal device is a cell of the mobile relay, a first access network device proactively reports current location information of the mobile relay to the core network device serving the terminal device, so that the core network device determines the location information of the terminal device based on the location information of the mobile relay. This resolves a problem that cell information of the mobile relay may not match an actual geographical location of the terminal device.

Abstract: A domain name system query method in which: a first network element receives a DNS query request including a first domain name from a terminal apparatus; the first network element sends first request information which comprises location information of the terminal apparatus and the first domain name to a second network element; the second network element determines, based on the first request information, an IP address and feeds back the IP address to the first network element; and the first network element sends the IP address to the terminal apparatus. When a terminal apparatus performs domain name query, a core network element determines an IP address of an application server based on location information of the terminal apparatus and a queried domain name. In this way, the terminal apparatus obtains an IP address of an application server close to the terminal apparatus, thereby improving service access efficiency of the terminal apparatus.

Abstract: A method and an apparatus for discovering an edge application server (EAS) are provided. A session management function (SMF) network element that serves a session of a terminal apparatus obtains information about at least one EAS, or obtains indication information of an EAS that cannot serve the terminal apparatus; and the SMF network element determines first information based on the obtained information, where the first information is used to determine information about an extension mechanisms for domain name system client subnet (ECS) option, or the first information is used to determine an address of a local domain name system (DNS) server, and the information about the ECS option or the address of the local DNS server is used to determine an EAS that serves the terminal apparatus. The first information is determined when the information about the EAS or the EAS that cannot serve the terminal apparatus is considered.
