Abstract: This application discloses an application discovery method and apparatus, and a system. A session management function network element receives first information from a first network element, and determines second information based on at least the first information and location information of a terminal device. The session management function network element sends the second information to the first network element. The second information is for obtaining a first IP address corresponding to a first domain name.

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: This application relates to a communication method and apparatus. A first access network device determines first expected assistance information and second expected assistance information based on matching information between a first quality of service (QoS) flow and a second QoS flow. The first access network device sends the first expected assistance information and the second expected assistance information to a first core network device, where the first expected assistance information and the second expected assistance information are used to re-determine transmission occasions of the first QoS flow and the second QoS flow. In embodiments of this application, resources of associated QoS flows may be coordinated, to avoid, as much as possible, a case in which a resource scheduled for a QoS flow does not match a resource scheduled for another QoS flow, and reduce a transmission delay of the QoS flow.

Abstract: This application provides an information transmission method, an apparatus, and a system. The method includes: A sensing network element receives location information of a first area from a first network element. The sensing network element receives first sensing data from a first device, where a sensing area corresponding to the first sensing data includes the first area, and the first device is configured to perform sensing. The sensing network element determines first information based on the location information of the first area and the first sensing data, where the first information indicates that a first terminal device is located in the first area. The sensing network element sends the first information to the first network element. Therefore, whether a terminal device is in the first area may be determined based on sensing data. This reduces signaling overheads.

Abstract: A data transmission method includes receiving third information from a session management network element. The third information includes first transmission delay information of data packet transmission between an access network element and a terminal device. The data transmission method further includes determining congestion control parameter information based on the third information, and sending the congestion control parameter information to the data sending network element. The congestion control parameter information is useable to indicate that a data amount of a first service sent by a data sending network element to a second user plane function network element for the first time after a user plane function network element that is configured to serve the first service in the data sending network element is switched from a first user plane function network element to the second user plane function network element.

Abstract: Embodiments of this application provide a packet transmission method, a communication apparatus, and a communication system. A target transport layer proxy network element establishes a fourth transport layer connection based on a first context of a source transport layer proxy network element, where the first context is a context about packet transmission of the source transport layer proxy network element on a first path. If the target transport layer proxy network element receives first indication information, and the first indication information indicates that application context migration between a first application server and a second application server is completed, the target transport layer proxy network element performs transport layer processing on a packet on a second path based on a second context of the target transport layer proxy network element, and transmits, on the second path, a packet obtained through the transport layer processing. Hence, a packet loss can be avoided.
