Abstract

The invention discloses a session reconstruction method, device and system, relates to the technical field of communication, and the session reconstruction method, device and system are helpful for improving the transmission performance of services. The method comprises the following steps: when a network slice instance related to a first PDU session of a terminal is unavailable and a network slice related to the first PDU session is available, an SMF network element sends first information to the terminal; wherein the first information is used for indicating the terminal to initiate a PDU session reconstruction process, wherein the PDU session reconstruction process is used for reconstructing a PDU session based on the network slice.

Description

technical field [0001] The present application relates to the technical field of communications, and in particular to a session reestablishment method, device and system. Background technique [0002] In the fifth generation (5rd generation, 5G) network architecture, the concepts of network slice (network slice) and network slice instance (network slice instance, NSI) are introduced. Network slicing is a network used to support logical isolation of specific network functions and network characteristics. It can include the entire network end-to-end (E2E), or some network functions can be shared among multiple network slices. Network slicing is a technology that meets the network differentiation requirements of 5G mobile communication technology. Usually, the network characteristics of different network slices are different, and the network slices are required to be isolated from each other without affecting each other. For example, network slicing for augmented reality (AR)...
