Developing a Multi-Protocol Mobility Manager for SIP/SS7 Networks

The global telecommunication networks would overcome geography and time differences. Recently, tele-communication equipment and service providers seek to connect the wireless mobile telecommunication networks to the Internet directly. These enhanced wireless mobile networks can result in a reorganized set of conventional functions for better developed services.In order to enable these functions, the enhanced All-IP based SS7 communication network is required. The standards associations such as 3rd Generation Partnership Project (3GPP) and 3GPP2 of mobile communication offer the Internet Protocol (IP) Multimedia Sub-system (IMS) as well as the Multi-Media Domain (MMD) systems. The numerous requirements and issues have been emerged in the changeover process of the wireless Signaling System No. 7 (SS7) for All-IP network. The crucial point is to ensure interoperability among heterogeneous networks. In this paper, a function named Multi-Protocol Mobility Manager (MPMM) is developed. It can satisfy the requirements and issues required in All-IP networks. The proposed MPMM enables roaming functions between 3GPP and 3GPP2 protocols, can reduce the load of the network, and provides other valuable services. The performance of the system is tested and evaluated. From the results of the performance tests, we believe that MPMM can help improve the networks functionalities.
