Design And Implementation Of IMS Service Emluator

To provide more kinds of Services and drive the combination of fixed network and mobile network, we are looking for a new network Structure. So 3GPP designed the IP Multimedia Sub system(IMS) in Release 5 to satisfy the needs, which is considered as the most suitable solution to Next Generation Network.As we all known, the most remarkable feature of 3G is the variable and enhancive multimedia applications. IMS provides universal platform for many kinds services coexisting. And SIP is defined as signaling protocol of IMS network by 3GPP, which separates services form bearers.But there are a lot of applications and the extension of SIP. It must be solved before the services of IMS are for commercial applications , including the interface of test and the coexistence of many kinds of operations.This paper focused on the feature of the IMS, achieved several tasks below, which based on the principle of SIP emulator.1. Analysis the IMS structureThe detailed Analysis about IMS and the characteristics of its services makes a clear definition about software's requirements.2. protocol analysisThe detailed analysis of SIP provides a foundation for the further protocol coding and decoding.3. implement the EmluatorAfter performing protocol analysis, protocol designation and network specification, that contributes to implementation of the Emlutor and the coding and decoding of protocols. It shows the detailed signaling...
