Radio communication system, base station device and communication terminal accommodated in the system

摘要

In a communication system that combines HDR system and IS-2000 system, when mobile station 101 receives an interruption request from IS-2000 system while performing high-speed packet communication system under HDR system, BTS 105 modifies priority of MS 101 higher than when there is no interruption request and assigns communication resources accordingly. By thus adequately operating HDR system and IS-2000 system, it is possible to offer a wireless communication system that efficiently combines the services of both systems, as well as a base station apparatus and a communication terminal for use in the system.
