Problems solved by technology

The current AMF load rebalancing method has the following problems: 1. In the case where AMF does not make backups, users may go offline because the user context cannot be obtained after the user migrates to the new AMF; 2. AMF load rebalancing is often Occurs when the AMF load is overloaded. In this case, the user will go offline and then go online again, and the signaling will double, which will undoubtedly increase the network load and increase the risk of signaling storms; 3. The current AMF load rebalancing It is based on the globally unique AMF identifier (GUAMI), that is, only all users on AMF can be migrated as a whole, and there is no user-level migration

Embodiment Construction

[0051] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0052] An embodiment of the present invention provides a load rebalancing processing method. figure 1 It is a schematic flow chart of the load rebalancing processing method in the embodiment of the present invention Figure 1 ;like figure 1 As shown, the method includes:

[0053] Step 101: The first AMF sends load rebalancing indication information to the terminal device, where the load rebalancing indication information is used to instruct the first AMF to rebalance the load.

[0054] In this embodiment, the AMF can receive all connection and session related information through the N1 interface with the user equipment (UE, User Equipment) or the N2 interface with the access network equipment (such as the base station gNB), and is responsible for processing the connection and Mobile management tasks, all messages related to session...

Abstract

The embodiment of the invention discloses a load re-balancing processing method, related network equipment and terminal equipment. The method comprises: a first access and mobility management function (AMF) sends load re-balancing indication information to a terminal device, the load re-balancing indication information being used for indicating load re-balancing of the first AMF.

Description

technical field [0001] The invention relates to the technical field of wireless communication, in particular to a load rebalancing processing method, related network equipment, and terminal equipment. Background technique [0002] Access and Mobility Management Function (AMF, Access and Mobility Management Function) load rebalancing refers to migrating users to other AMFs due to reasons such as the AMF load is too high or the AMF is about to retire. The current AMF load rebalancing method has the following problems: 1. In the case where AMF does not make backups, users may go offline because the user context cannot be obtained after the user migrates to the new AMF; 2. AMF load rebalancing is often Occurs when the AMF load is overloaded. In this case, the user will go offline and then go online again, and the signaling will double, which will undoubtedly increase the network load and increase the risk of signaling storms; 3. The current AMF load rebalancing It is based on t...
