Abstract:IMS which is put forward in 3GPP R5 can provide uniform architecture and infrastructure in mobile communication network for IP multimedia services. Based on analysis of the service requirements, this article gives out the solution about the instant communication system composed of IM, PoC, Presence and XDM subsystems. The typical example of service flow aims to give more details about how the system provides instant communication service to mobile users. At last some detailed questions are brought forward for further study.
Keywords:IMS  IM  PoC  Presence  XDM
