METHOD AND SYSTEM FOR PROVIDING HARD HANDOFF BETWEEN PORTABLE INTERNET NETWORK AND OTHER NETWORKS BY USING BORDER REPEATER

摘要

The present invention relates to a method and system for using a border relay provides a hard handoff between a portable Internet network and a different type of network. ; The present invention, the portable Internet network (Portable Internet Network) and a PSS using a different kind of border (Border) a repeater is installed in the boundary area of ​​the network to move from the serving (Serving) side communication network to the target (Target) side network With such a method for a hard handoff (hard handoff), (a) when moving towards the coverage area of ​​the target-side communication network through the coverage area of ​​the border repeater is the PSS in the coverage area of ​​the serving-side communication network, that at the boundary of the coverage area and the coverage area of ​​the border repeater of the serving-side communication network without terminating the communication with the serving side of the base station of the serving-side communication network to start the border repeater and a communication, the serving-side base station and the border repeater performing a soft handoff between; And (b) when the individual subscriber terminal moves to the border areas of the coverage area of ​​the coverage area and said target-side communication of the border repeaters, end the communication with the serving-side base station, and the target-side base station of the target-side communication network how to start the communication, using the border repeater characterized in that it comprises a step of performing the serving-side base station, and the hard handoff between the target-side base stations that provide a hard handoff between a portable Internet network and a different type of network and to a system to do this. ; Hard handoff, soft handoff border repeater, individual subscriber terminal, the portable Internet network, the base station, RAS
