Registration, communication and switching method of mobile nodes and device thereof

Abstract

The present invention relates to mobile communication technologies, and discloses a method and an apparatus for registration, communication, and handover of a Mobile Node (MN). The present invention is intended to overcome the bottlenecks of data traffic and processing capability in the home network in the prior art. A distributed mobility management system is provided herein. The system includes at least two Mobility Management Anchors (MMAs): any two MMAs are interconnected; at least one terminal exists in each MMA connection; each MMA stores a terminal binding relationship table; and the terminal binding relationship table records identifiers (IDs) and Internet Protocol (IP) addresses of terminals. The distributed mobility management system under the present invention can balance load, improve the data processing capability, simplify the signaling interaction in various procedures, and improve the system processing capability.

Description

technical field [0001] The invention relates to the technical field of mobile communication, in particular to methods and devices for registering, communicating and switching mobile nodes. Background technique [0002] MIP (Mobile Internet Protocol, mobile Internet protocol) supports the connectivity of MN (Mobile Node, mobile node) when moving in the IP network, so that the MN can still maintain the connection with the network after leaving its home network. The MN always uses the HoA (Home Address, home address) assigned by the home network (Home Network) for identification, and does not change due to changes in the visited network; when the MN leaves the home network, it will be assigned with the CoA (Care Of Address, care-of address), the MN's current location is identified by the CoA, and it will send its current location information to the HA (Home Agent, home agent) at the same time. The HA will intercept the data packet sent by the CN (Corresponding Node, opposite e...

Problems solved by technology

[0005] The use of HA in the home network (Home Network) causes most of the signaling and data transmission to pass through the device, making it a performance bottleneck

Although it has been optimized and multiple HAs are used in the home network to support a large number of MNs, it still cannot completely solve the problem that the home network becomes the bottleneck of data traffic and processing capacity; management, resulting in complex HA design and heavy burden
