WIMAXGW BASE STATION APPARATUS AND WIMAX HANDOVER CONTROL SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide a WiMAXGW (Worldwide Interoperability for Microwave Access Gateway) base station apparatus and WiMAX handover control system capable of suppressing packet loss caused when a mobile terminal is handed over to the minimum.;SOLUTION: The WiMAXGW base station apparatus 36 in the WiMAX handover control system 10 includes a base station 32a for carrying out wireless connection with a mobile terminal 12 and an ASNGW 34a for connecting the base station 32a to a CSN 18, and controls handover when the mobile terminal 12 changes the wireless connection from a base station 22a to the base station 32a. An ASN 20 to which the base station 22a and an ASNGW 24a connected to the base station 22a belong is different from an ASN 30 to which the base station 32a and the ASNGW 34a connected to the base station 32a belong, and the communication path between the mobile terminal 12 and the CSN 18 after the mobile terminal 12 is handed over from the base station 22a to the base station 32a is established so as to include the communication path between the ASNGW 24a and the ASNGW 34a.;COPYRIGHT: (C)2009,JPO&INPIT
