Abstract: This application provides a communication method and apparatus, and relates to the field of communication technologies, to resolve the following problem: resource shortage or communication congestion easily occurs on a network slice instance because the network slice instance is selected based on a fixed correspondence between a network slice and a network slice instance. The method includes: learning, by an access and mobility management function network element, that load information of a first network slice instance reaches or exceeds a threshold, where the first network slice instance serves a first session; sending indication information to a session management function network element corresponding to the first session, where the indication information is used to trigger establishment of a second session; and determining a second network slice instance for the second session, where the first network slice instance and the second network slice instance correspond to a same network slice.

Abstract: A first edge configuration server receives a first request message, sends an application function request message to a policy control function network element, and sends a response message for the first request message. The first request message includes an application client profile. The application function request message is used to request to configure a data forwarding path from a terminal to a visited edge enabler server and/or a visited edge configuration server. In embodiments of this application, data sent by the terminal to the visited edge enabler server and/or the visited edge configuration server may be distributed to a visited domain via a visited user plane function network element, instead of being forwarded to a home user plane function network element.

Abstract: This application provides a communication method and apparatus. The method includes: A first device determines information about service flow arrival time, where the information includes time at which a first service flow (a periodic service flow to be transmitted between an access network device and a user plane network element) arrives at a second device. The first device determines information about service flow sending time based on the information about the service flow arrival time. The first device indicates the second device to wait, after receiving the first service flow, until the service flow sending time to send the first service flow. If the first service flow is an uplink service flow, the second device is the access network device or a translator corresponding to the access network device; or if the first service flow is a downlink service flow, the second device is the user plane network element.

Abstract: A method includes a communication apparatus receives first parameter information of an air interface scheduling resource allocated by an access network device accessed by a terminal device, where the first parameter information includes a length of a first periodicity and a first start moment. The communication apparatus determines, based on the first parameter information, second parameter information of a scheduling resource for processing first uplink data, where the second parameter information includes a length of a second periodicity and a second start moment. Based on the foregoing solution, the communication apparatus receives the first parameter information of the air interface scheduling resource, and adjusts, based on the first parameter information, a periodicity and/or a start moment for locally processing the uplink data, so that an end-to-end latency is reduced, thereby improving user experience.

Abstract: This application provides a data transmission method and communications devices. In some implementations, a terminal device receives, from a first server, first indication information indicating a sequence number of data that is of an application and that has been received by the first server from the terminal device. After a connection between the terminal device and a second server is established, the terminal device transmits data of the application through the connection between the terminal device and the second server according to the first indication information.

Abstract: According to a communication method and a communications apparatus, in a process in which an access network device serving a terminal is handed over from a source access network device to a target access network device, a user plane function network element may transmit first information to the source access network device. The first information is used to indicate that the user plane function network element bicasts downlink packets to the source access network device and the target access network device, so that after determining that a data packet received before the first information is sent to the terminal, the source access network device triggers an air interface handover, to avoid a packet loss in a handover process, or so that the source access network device synchronizes a PDCP SN of the source access network device with a PDCP SN of the target access network device.
