Abstract: This application provides a satellite communication method and apparatus. The method may include: A session management network element obtains first service information, where the service information indicates one or more services supported by a satellite. The session management network element determines, based on the first service information, whether a terminal device is allowed to access the services supported by the satellite. When determining that the terminal device is allowed to access at least one of the services supported by the satellite, the session management network element inserts a user plane network element on the satellite into a user plane path of the terminal device. According to the foregoing solutions, a delay in satellite communication of the terminal device can be reduced, and user experience can be improved.

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: Embodiments of this application provide a media packet transmission method, an apparatus, and a system that relate to the field of communication technologies. In an example method, a transmit end network element obtains a correspondence between an encoding type and a quality of service (QoS) flow. The transmit end network element is a user plane network element or a terminal. The QoS flow is used to transmit a media packet whose encoding type is the encoding type corresponding to the QoS flow. The transmit end network element identifies an encoding type of a received media packet, and sends, based on the correspondence through a QoS flow corresponding to the encoding type of the media packet, the media packet carrying information associated with the encoding type to an access network element.

Abstract: The present disclosure provides example traffic routing methods, apparatuses, and systems. One example method includes determining, by a session management network element, a routing rule, where the routing rule indicates a first traffic steering entity to send a first traffic to a first function entity, or send a second traffic to a second function entity or an access device, where the first traffic is a traffic on which first traffic steering control is to be performed, and the second traffic is a traffic on which the first traffic steering control has been performed. The routing rule is sent by the session management network element to the first traffic steering entity in a session management process.
