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: The present disclosure relates to communication methods and communication apparatuses. In one example method, a first data analytics network element receives first information of an application from a first network element, where the first information includes at least one of first application description information or an application status that correspond/corresponds to the application. The first application description information includes an application identifier and first IP information that correspond to the application, and the application status includes a foreground state or a background state of the application. The first data analytics network element determines second information based on the first information. The first data analytics network element sends the second information to a second 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: The present invention relates to the field of communications technologies and discloses service transmission methods, apparatus, and devices. In one embodiment, a method includes: obtaining, by a target server or user equipment, an Internet Protocol (IP) address assigned by a target gateway to the user equipment; establishing a Multipath Transmission Control Protocol (MPTCP) connection between the user equipment and the target server based on the IP address assigned by the target gateway to the user equipment, where the MPTCP connection between the user equipment and the target server and an MPTCP connection between the user equipment and a source server are bound to a same MPTCP session; and transmitting a service data packet using the MPTCP connection between the user equipment and the target server. The service data packet is transmitted using the target gateway so a transmission path is optimized and a service transmission delay is reduced.
