基于IMS的PoC业务仿真系统的设计与实现

IMS that is brougt forward by 3GPP is a subsystem that supports the service of IP and multimedia.IMS includes advantages such as independence of connection,inteface of service control that is opening-standards and so on.IMS that is based on IP and supports services such as voice,data and multimedia,providers the foundation of fusing service. PoC is an instant communication implementation service of IMS.PoC that is simple , convenient,fast-communicating ,push to talk ,talk in group,is thougt that it may be the one of the most important application of mobile increment service. This paper describes the design and implementation of emulating system of IMS-Based PoC Service. This article first introduced the background of IMS, SIP and PoC business and other related knowledge, and then put forward a design and implementation of the program.
