Abstract: This application provides methods, devices, and systems. In an example method performed by a session management network element, the session management network element receives a first policy and charging control (PCC) rule from a policy control network element, wherein the first PCC rule comprises indication information, and the indication information indicates that a service corresponding to the first PCC rule is a time sensitive service. The session management network element binds the first PCC rule to a quality of service (QoS) flow, wherein no other PCC rule is bound to the QoS flow.

Abstract: Embodiments of this application provide a communication method, a communication apparatus, and a communication system. A proxy client of a terminal device receives application data traffic from an application client of the terminal device; the proxy client determines first data traffic and second data traffic based on the application data traffic, and the first data traffic, the second data traffic, and the application data traffic include same data; and the proxy client sends the first data traffic to a proxy server by using a first session, and sends the second data traffic to the proxy server by using a second session, where the first session and the second session are redundant sessions for each other. In this solution, the proxy client and the proxy server implement redundant transmission of the application data traffic, to ensure correctness and reliability of data transmission, and help improve user experience.

Abstract: Embodiments of the present disclosure include a method, a device, and a system for deploying a network slice. The method, device, and system disclosed herein are related to the field of communications technologies and are designed to solve the problem of low efficiency in manually deploying a network slice. In an exemplary solution, a first network management unit receives a network slice management request message that carries service traffic information of a network slice, and, based on the service traffic information of the network slice, deploys the network slice or selects an available network slice in an existing network.

Abstract: A service transmission method and apparatus are provided to establish a connection between an access and mobility management function network element and a secondary base station, when a master base station is not capable of continuing to provide a service for a terminal device. In an embodiment, an access and mobility management function network element determines that a master base station is not capable of continuing to provide a service for a terminal device. The access and mobility management function network element sends a mobility management context of the terminal device to a secondary base station, where the mobility management context is used by the secondary base station to perform mobility management on the terminal device. Therefore, a signaling connection between the access and mobility management function network element and the secondary base station can be quickly established, thereby ensuring service transmission and improving user experience.
