TD-SCDMA终端RRC连接建立过程研究

Research on procedure of RRC connection setup in TD-SCDMA

无线资源控制(RRC)子层位于空中接口协议栈的第3层,它主要完成无线资源的控制和管理功能。文章的研究对象是RRC子层连接建立过程,即信令连接建立过程,详细分析了该过程的具体流程和可能出现的异常情况,并对资源的分配做了简要描述。

RRC lies in the 3rd sublayer of air interface protocol stack,the main function of which is the control and management of radio resource. In the document, the procedure of RRC Connection Setup is the main object of research , some abnormal cases and the allocation of the radio resource are also analyzed.
