Abstract: This application provides a communication method and apparatus. The method may include receiving, by a second session management network element in a visited network, from a first session management network element in a home network, indication information, wherein the indication information indicates that traffic routing is allowed in the visited network. The method may further include sending, by the second session management network element and based on the indication information, IP address information of the visited network to a user plane network element in the visited network, wherein the IP address information is information used to determine an extension mechanisms for domain name system DNS client subnet option, or the IP address information is a local DNS server address.

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: A communication method and apparatus. A session management function obtains at least one group of first association relationships, where the first association relationship is a correspondence between identification information of domain name system DNS handling information and the DNS handling information. The SMF sends, to an EASDF, the at least one group of first association relationships used for PDU sessions of a plurality of terminal devices, and sends, to the EASDF, a first message corresponding to a first PDU session, where the first information includes first identification information, and the first identification information is identification information of DNS handling information corresponding to the first PDU session. The EASDF receives the first association relationship and the first message, and determines, based on the first association relationship and the first identification information, the DNS handling information corresponding to the first PDU session.

Abstract: This application provides a communication method and apparatus. The method may include: A first session management network element determines an offloading point in a visited network based on first information, where the first information indicates that offloading is allowed in the visited network, and the first session management network element is a network element deployed in the visited network; and the first session management network element sends an offloading rule to the offloading point, where the offloading rule is for offloading a packet to the visited network. According to this application, after accessing the visited network through HR roaming, a terminal device may access a service in the visited network by using the offloading point determined by the first session management network element, to implement local offloading in the visited network.

Abstract: This application provides an information transmission method and apparatus. The method may include: A first session management network element selects an edge application server discovery network element, where the first session management network element and the edge application server discovery network element are network elements deployed in a visited network. The first session management network element sends address information of the edge application server discovery network element. In this way, after accessing the visited network through HR roaming, a terminal device may access a service in the visited network by using the edge application server discovery network element selected by the first session management network element.

Abstract: A communication method and apparatus, and a computer-readable storage medium. First request information is received from a terminal device, where the first request information includes first application identification information. Second information is determined based on the first application identification information and first information obtained from a session management function network element, where the second information includes extended mechanisms for DNS client subnet option or address information of a local DNS resolver. DNS request information is sent to a central DNS server or the local DNS resolver based on the second information, where the DNS request information includes the first application identification information, and the DNS request information is usable to obtain address information of an application server.
