一种基于窄带无线用户接入IMS的无线接入控制技术

Radio Access Control Technique Based on Narrowband Wireless MS Accessing IMS

IMS是3GPP在Release 5版本提出的支持IP多媒体业务的子系统,其核心特点是采用SIP协议和与接入的无关性。就IMS支持SIP协议和与接入的无关性,在带宽资源有限的情况下针对窄带无线用户接入IMS,重点提出了一种典型的无线接入控制技术,并详细分析其在系统中的位置、框架结构、系统结构、接口定义以及典型功能的实现方式。

IMS （IP Multimedia Subsystem） is the subsystem supporting IP multimedia service, which was proposed in 3GPP Release 5. Because of IMS supporting the independence between SIP protocol and access, a typical radio access control technique was put forward according to narrowband radio MS accessing IMS in the condition of limited bandwidth. The position, architecture, system structure, interface definition and typical function implementation of the technique were elaborated.
