Abstract

The invention relates to a method for realizing seamless switch of mobile joint based on mobile IP. In the method, the mobile joint in the wireless communication network is set with two states of 'communication' and 'idle', then, in the set call region (or MAP region), the shift to the forward joint need not the MAP to carry on updating the registration, it carries on registration updating to MAP through AR when the mobile joint starts the communication or starts the communication pointing to the mobile joint. Thus, the invention reduces the times of registration updating of mobile joints in the MAP region, reduces the signaling outgoings of switch greatly, maintains the localization information of idle host computer and reduces the localization updating frequency, it avoids the decrease of effective charge of network caused by the tiny shift of mobile joints frequently.

Description

technical field

[0001] The field of the invention relates to the field of wireless communication technology, and mainly relates to a method for realizing seamless handover of a mobile node device adopting mobile IP technology in a micro-mobility area in a wireless communication system. Background technique

[0002] In the wireless communication network, the handover algorithm of the mobile device adopting the Mobile IP (Internet Protocol) technology in the micro-mobility environment is currently a research hotspot in the field of Mobile IP. How to overcome the excessive signaling overhead and data loss caused by handover in the micro-mobility environment is the key to the formal commercialization of mobile IP.

[0003] Seamless MIP (Seamless Handover Mobile IP) technology is a mobile IP architecture with no packet loss QOS (Quality of Service) guarantee based on the hierarchical mobile IPv6 architecture and fast handover mechanism. In this architecture, when the mobile node...
