Problems solved by technology

However, in practice, each terminal device moves to modify the MAC address forwarding table, which will cause waste of resources, and the possibility of modification failure or incomplete modification during the modification of the MAC address forwarding table is very high, and business continuity cannot be guaranteed.
Therefore, the above method cannot flexibly realize the switching of the forwarding path

Abstract

A mobility management method and device are used to flexibly implement switching of forwarding paths and ensure service continuity during terminal equipment movement. The method includes: after the first terminal device moves, the control plane network element determines the changed media access control address MAC address of the first terminal device; and then, the control plane network element determines that the first terminal device belongs to At least one second terminal device belonging to the same terminal device group, wherein the first terminal device is a terminal device whose address has changed after moving, and the at least one second terminal device is the Finally, the control plane network element notifies the first terminal device and the at least one second terminal device to update the changed MAC address of the first terminal device.

Description

technical field [0001] The present application relates to the field of communication technologies, and in particular to a mobility management method and device. Background technique [0002] In industrial networks, Ethernet is the basis of industrial Ethernet protocols, and supporting Ethernet will help 3GPP to implement industrial control networks. In Ethernet, when terminal devices are in the process of business communication, after a terminal device moves, it is necessary to switch the access device of the terminal device and switch the forwarding path of the external switching network at the same time, so as to completely update the end-to-end forwarding path. [0003] At present, when a terminal device moves, it is necessary to update a network-wide media access control address (media access control address, MAC) address forwarding table to switch forwarding paths. However, in practice, each terminal device moves to modify the MAC address forwarding table, which will ...
