Mobility Management System and Method for Distributed Mobility Management Network

摘要

PURPOSE: A mobility management system for a distributed mobility management network and a method thereof are provided to effectively transmit data without overlapping with unnecessary packets by using transmission node information. CONSTITUTION: Portable terminals(110,120) receive a network access service from MMAAs(Mobility Management Anchor Agents)(130,140) by wirelessly connecting a base station. The MMAA updates and generates a binding message and manages an access path of the portable terminal based on binding information. An MMIS(Mobility Management Information Server)(150) manages information about a network or an agent transmitting data and a multicast channel.
