Embodiment Construction

[0157] In order to make the purposes, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments These are some embodiments of the present invention, but not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0158] figure 1 It is a schematic diagram of the structure of the mobility management system in the prior art; such as figure 1 As shown, in the communication system, when the MN initially accesses the first network, the HA allocates a HoA to the MN; after that, the MN uses the HoA to communicate with the CN. When MN is along fig...

Abstract

Embodiments of the present invention provide a mobility management method, device and system. Sending a first BA message to the MN through the HA-C, the first BA message including the address of the first HA-U, so that the MN communicates with the first HA-U according to the first BA message Tunnel communication; the HA-C sends a configuration message to the first HA-U, the configuration message includes the HoA and CoA of the MN, so that the first HA-U communicates with the first HA-U according to the configuration message The MN performs tunnel communication; the original proxy server or gateway only completes the tunnel communication with the MN, and the newly added proxy server completes the control signaling interaction with the BU; thereby reducing the load of the original proxy server or gateway, and solving the problem in the prior art A problem with a heavily loaded proxy server or gateway.

Description

technical field [0001] Embodiments of the present invention relate to communication technologies, and in particular, to a mobility management method, apparatus, and system. Background technique [0002] With the gradual convergence of the Internet and mobile communication, more and more people access the Internet anytime and anywhere through mobile nodes (eg, cell phones). [0003] In the prior art, when a mobile node (MN, Mobile Node) initially accesses the first network, the MN obtains a local address (HoA, Home Address) assigned to it by a home agent (HA, Home Agent) in the first network, and the MN Use HoA to communicate with the peer node (CN, Correspondent Node). When the MN moves to the second network, it obtains a care-of-address (CoA, Care-of-Address) assigned to it by the second network. After that, the MN sends the HoA and CoA to the HA through a binding update (BU, Binding Update) message; the HA creates a binding cache entry (BCE, Binding Cache Entry) for the ...
