The Caller Of. Camel4 System Processing Model And Realization

Current mobile communication system uses the CAMEL (Customized Applications for Mobile network Enhanced Logic) technology to implement all kinds of wireless intelligent services for the users. But with the development of 3rd Generation Mobile Communication Technology, the current CAMEL system couldn't suffice the development. So the 3GPP Organization designed the CAMEL4 (CAMEL Phase4), the new generation of CAMEL technology. The main characteristic of CAMEL4 is Call Party Handling (CPH).This thesis mainly discusses the CPH characteristic and its implementation.The following three aspects are discussed: the principle of CAMEL and CAMEL4, the analysis of CPH characteristic and the implementation of CPH characteristic. Firstly, this thesis introduces the principle of mobile communication, the principle of CAMEL, and the new characteristics of CAMEL4. Secondly it analyzes the CPH characteristic, the CAP operations (messages) of CPH and the message flow of CPH operations. At last, it discusses the implementation of CPH in some kind of software switched MSC.The project that implements CAMEL4 in some kind of software switched MSC has started. And the useable version will be put into market at the end of this year with the plan.
