摘      要：Traditional telecommunication network provides a variety of multimedia services based on IP. While IP Multimedia Subsystem (IMS) is gaining more and more interests from the industry, a set of problems have to be faced such as centralized control, low efficiency and poor scalability of core equipment, especially compared with the IT environment using cloud computing. One of the more important reasons which IMS could not adopt those IT technologies is IMS highly relies on Session Initiation Protocol (SIP) and SIP is a session based protocol which is not compatible with transaction based IT environment. In this paper, Cloud SIP System (CSS) is brought forward to decompose SIP sessions into transactions. The introduction of CSS could facilitate the migration of IMS from the traditional dedicated infrastructure into the shared infrastructure to promote both the use ratio of the infrastructure and the scalability of the system.
