UMTS中一种新的RAN结构及其接入控制技术的研究 论文重点研究了这种架构下的关键技术之一一呼叫接入控制技术。文章在分析未来移动通信系统特点的基础上，认为HCS(分层小区结构)是未来移动通信的主要覆盖模式。那么在HCS覆盖模式

下的IP．RAN中的呼叫接入控制策略可以分解为：无线资源部分的层选择技术、接入控制技术和切换技术和IP．RAN网络部分的接入控制技术、切换技术。-This paper focuses on the key technology of the framework of a call access control skills

Art. Based on the analysis on the future of mobile communication system, based on the characteristics of HCS (that stratified

District structure) is the main cover for future mobile communication mode. So in HCS coverage model

The IP. Under the call access control strategy RAN can be decomposed to the layer: wireless resources section

Select technology, access control technology and switching technology and IP. RAN the access control network part

Technology, switching technology.
