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. 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.

Abstract: Embodiments of this application relate to the field of communication technologies, and provide a method for determining an edge configuration server and an apparatus, to select a more proper edge configuration server for a terminal apparatus. The method includes: A core network element determines, based on a mobile network accessed by a terminal apparatus, that an edge configuration server serving the terminal apparatus is a first edge configuration server, where at least one mobile network corresponding to the first edge configuration server includes the mobile network accessed by the terminal apparatus. The core network element sends, to the terminal apparatus, information indicating the first edge configuration server.

Abstract: Embodiments of this application provide a method and an apparatus for adjusting a media parameter. The method includes: A terminal device obtains network information from a network data analytics function network element, where the network information includes one or more of the following: network performance prediction information or a media parameter, the network performance prediction information indicates prediction of a network status, and the media parameter is used for controlling, selecting, transmitting, or buffering media data. The terminal device processes the media data based on the network information. In embodiments of this application, a freezing phenomenon can be reduced by adjusting a media parameter, and quality of experience of a user can be improved.

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.
