Problems solved by technology

However, terminal equipment often moves, resulting in handover of the user plane network element corresponding to the terminal equipment. At this time, if the terminal equipment still accesses the application server accessed before the handover, it cannot be guaranteed to achieve reliable and ultra-low latency. business processing

Embodiment Construction

[0042] Embodiments of the present application are described below with reference to the drawings in the embodiments of the present application.

[0043] The present application provides a communication system such as figure 1 A schematic structural diagram of a communication system provided by the embodiment of the present application is shown. The communication system 1000 may include a user plane network element 100 and a session management network element 101 , and further, the communication system may further include a terminal device 102 and a network opening network element 103 . The communication system 1000 is connected to the mobile edge platform 2000 . One or more local application servers 200 providing the same service are deployed on the mobile edge platform 2000 (only one local application server is illustrated here). Specifically, each mobile edge platform 2000 deployed with a local application server 200 is connected to one user plane network element 100, and ...

Abstract

The invention discloses a switching method of an application server, a session management network element and terminal equipment. The method comprises the steps that an SMF obtains an address of a local application server corresponding to a switched UPF according to the switched UPF and the corresponding relation between the UPF and the address of the local application server; and the SMF sends the address of the local application server corresponding to the switched UPF to the UE. The invention further discloses a corresponding device. According to the method and the device, in the scene thatthe UPF corresponding to the UE is switched, the UE can access the local application server corresponding to the switched UPF, so that the UE can obtain reliable low-delay service provided by the local application server.

Description

technical field [0001] The present application relates to the technical field of communications, and in particular to a method for switching an application server, a session management network element, and a terminal device. Background technique [0002] Mobile edge computing (MEC) is a technology that deeply integrates access network and Internet services based on the fifth generation (5G) mobile communication architecture. It deploys the application server (application server, AS) and mobile broadband (MBB) core network part of the business processing and resource scheduling functions to the edge of the network close to the access network, and processes the business close to the user to achieve reliable, Ultra-low latency business processing. [0003] Usually, in order to provide the ultimate service experience, application servers providing the same service are deployed on adjacent mobile edge platforms (mobile edge platform, MEP). The MEP is connected to the correspond...
