Problems solved by technology

[0003] However, when the terminal equipment is other mobile terminal equipment such as mobile phones, the position of the terminal equipment is not fixed, and compared with the fourth-generation mobile communication technology (4-Generation, 4G), in 5G, the deployment position of UPF is more flexible. The service scope of the service will also change greatly with the change of the deployment location, and the mobility management and the session management are separated into two entities. Therefore, in order to provide better services for the data communication of the terminal equipment, it is necessary to rebuild the user plane path, but the existing 5G standard does not explicitly activate the mechanism for initiating user plane path reconstruction. Therefore, the embodiment of this application provides a method for initiating user plane path reconstruction

Embodiment Construction

[0068] The application will be described in further detail below in conjunction with the accompanying drawings.

[0069]It should be noted that the session management functional entity, the mobility management functional entity, and the user plane functional entity in the embodiments of the present application are only names, and the names do not limit the device itself. In the future 5G network and other networks in the future, the network elements or entities corresponding to the session management function entity, the mobility management function entity, and the user plane function entity may also have other names, which are not specifically limited in this embodiment of the present application . For example, the session management functional entity may be a session management function (Session Management Function, SMF), and the mobility management functional entity may be a core network access and mobility management function (Core Access and Mobility Management Function, ...

Abstract

A method, apparatus and communication system for initiating user plane path reconstruction are used to provide better services for sessions of terminal equipment to improve user experience. The method includes: the session management function entity determines, according to the first location information of the terminal device, the session service area to which the current session of the terminal device belongs; After the location information is obtained, if it is determined that the second location information is not within the session service area, the terminal device is instructed to initiate a reestablishment procedure for the current session, or initiate a handover procedure. Due to the introduction of the session service area, when the terminal device moves back and forth at the edge of the service area of ​​two adjacent user plane functional entities, the ping-pong effect caused by switching back and forth between the two user plane functional entities is avoided, thereby Improved user experience.

Description

technical field [0001] The present application relates to the field of communication technologies, and in particular to a method, device and communication system for initiating user plane path reestablishment. Background technique [0002] In the fifth-generation mobile communication technology (5-Generation, 5G), mobility management and session management are split into two entities, namely Core Access and Mobility Management Function (Core Access and Mobility Management Function, AMF) and Session Management Function (SMF). The AMF is responsible for the mobility management of the terminal equipment, including formulation of a tracking area list (Tracking Area List, TA List). The SMF is responsible for session management, including selection of a user plane function (User Plane Function, UPF), establishment of a packet data unit (Packet Data Unit, PDU) session, and the like. Moreover, in 5G, UPF can be divided into N3 UPF and PDU Session Anchor UPF (referred to as PSA, PD...
