摘要： 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.

摘要： This application provides a communication method and apparatus. In the method, each URSP rule included in a URSP corresponds to an HPLMN or a VPLMN of a UE. When the UE accesses an application, based on existing URSP rule matching, the UE uses PLMN information in the URSP rule as one of criteria for the UE to match a URSP rule, so that the UE can match the same application to different URSP rules in different PLMNs.

摘要： This application provides a communication method and apparatus. The method includes: 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 edge application server discovery function EASDF, the at least one group of first association relationships used for protocol data unit 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. This improves service experience of a user and information processing efficiency.
