Simulation and Service Implementation of Analog IMS Platform

Abstract

IMS is the most widely used network platform architecture in the world. It is a distributed IP service control system with independent access and open standard interface. It can achieve the integration of multi-network and multi-domain. It is the forefront of current network technology research. This article uses the IMS architecture in the 3GPP R8 version as the model, uses the Open IMS Core open source project to build the IMS core architecture, in conjunction with the use of SIP application server and the open source UCT client. The simulation of the network elements such as CSCF, HSS, UE and BGCF in the IMS architecture, the trigger of related services and the interworking of users are realized, which provides a good model for the construction of IMS platform in the future, and it is of great significance.
