SYSTEM AND METHOD FOR TRANSFERRING CONTEXT DURING HAND-OVER OF WIRELESS MOBILE NODE IN WIRELESS NETWORK

摘要

PROBLEM TO BE SOLVED: To provide a system and method for transferring context during hand-over of a wireless mobile node in a wireless network in which unnecessary resource utilization of an access point is reduced while transferring the context of the wireless mobile node to the access point before information transfer in response to movement of the wireless mobile node. SOLUTION: The method includes steps of: setting transfer boundaries according to positions spaced from an initial access point (AP) to which the wireless mobile node is initially connected, and determining peripheral AP types based upon the set transfer boundaries; and, prior to hand-over of the wireless mobile node in response to its movement, transferring a service context while making the context transfer policies different from each other according to the determined AP types among the peripheral APs arranged in the moving direction of the wireless mobile node.
