Embodiment Construction

[0362] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0363] Embodiments of the present invention provide a mobility management method, device and system. An LTE (Long Term Evolution, Long Term Evolution) cellular network is taken as an example for illustration. The LTE cellular network includes: a first base station, a second base station, a first gateway, a second gateway, a first mobility management entity (Mobility Management Entity, MME), a second mobility management entity, user equipment, and a communicati...

Abstract

Embodiments of the present invention provide a mobility management method, device, and system, which relate to the communication field and can effectively ensure normal communication between the user equipment and the base station without passing through the anchor device, and ensure that the user equipment and the communication peer business continuity between. The specific solution is: the user equipment establishes the first subflow at the communication peer, when the user equipment is handed over from the first base station to the second base station, when the second gateway is not the same gateway as the first gateway, the user equipment obtains the second IP address , the user equipment establishes the second subflow with the communication peer after obtaining the second IP address, the communication peer revokes the first subflow after the second subflow is established, and the first gateway releases the first subflow after the first subflow is revoked. IP address. The invention is used for mobility management in wireless network.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a mobility management method, device and system. Background technique [0002] The current communication technology has developed various access technologies, such as 2G / 3G / 4G access technology of cellular network, WLAN (Wireless Local Area Networks, wireless local area network) access technology, optical fiber access technology and Bluetooth access technology. technology etc. Multiple access technologies can be integrated in a communication terminal, and how to effectively utilize various access technologies in a communication terminal (such as a user terminal) to improve communication efficiency and user experience is one of the current technical hotspots. [0003] Among the technologies for realizing multi-path access, MPTCP (Multi-Path Transmission Control Protocol, Multi-Path Transmission Control Protocol) technology is a relatively mature one, which can dist...
