GSM/GPRS系统无线资源分配的研究

Study of radio resource allocations in GSM/GPRS system

通用分组无线业务 ( GPRS:general packet radio service) ,是一种基于 GSM( global system formobile communications)的新承载业务 ,它极大地提高并简化了通过无线方式对 Internet的访问。 GPRS与GSM的话音和基于电路交换的数据业务一起共享 GSM的频带。主要研究了 GPRS和传统 GSM业务之间无线资源分配方案 ,利用呼叫允许控制器和带宽分配器获得较高的带宽利用率而不影响传统 GSM业务和GPRS的服务质量 Qo S。

GPRS(general packet radio service)is a new b ea rer service for GSM(Global System for Mobile Communications)that can greatly i mprove and simplify wireless access to Internet. GPRS shares GSM frequency bands with telephone and circuit-switched data traffic. In this paper,the authors introduced proposed scheme about radio resource allocation, and utilized c all admission controller and bandwidth allocation controller to increase bandwidth utilizatio n without affecting the QoS of GSM and GPRS service.
