Moving management method for distribution type user's network

Abstract

The invention discloses a managing method for mobile communication between high-destruction resisting distributed user networks, adopting the change of management mechanism on existing management entity to implement user position updating and change of inquiry method. The hometown proxy of the invention can automatically grow and synchronize according to network condition and actual use condition, and can complete distributed user register and inquiry for a user. Using existing wireless access network like 802.11 network, and adopting the method of the invention can compose a high-destruction resisting and reliable communication network, implementing communication requirement in some emergency occasions (such as the conditions of earthquake, large-range natural disaster, military application, etc.).

Description

technical field [0001] The present invention belongs to the field of mobile communication using wireless, such as wireless communication, Internet, personal communication, wireless self-organizing network, etc., especially those that need to provide support for mobile users and require high invulnerability and reliability to integrate multiple heterogeneous In the network structure of the network. Background technique [0002] As we all know, user mobility management is a mechanism that provides a time-varying mapping between the mobile user's identity (user name) and its address (the user's location relative to the network structure), and is a mechanism that supports roaming users to reach a new service area to receive services. Basic technology whose main function is to effectively support seamless roaming of users and devices within the entire service network. It mainly manages the user's location, including addressing, location update, registration, query, tracking and ...

AI Technical Summary

Problems solved by technology

GSM uses a centralized mobile management method, which will generate a lot of management overhead when the user mobility is high, which is easy to cause congestion in the network, and the reliability and invulnerability are low

There are also several limitations when using MIP: the location of HA must be located in the home network; the vulnerability of HA, which does not allow other geographically dispersed HAs outside the home network; triangular routing and tunnel problems, etc.

The first two problems limit the persistence of the network, and the latter two problems reduce performance and prevent interoperability

SIP is suitable for real-time applications but not for non-real-time applications, and requires new transport layer protocols such as SCTP to adapt to changes in business flows
