The design of a signaling system in an enterprise network system

An enterprise communication system has the requirements of data, voice, and mobile communications. We have proposed iNetwork as an enterprise-based communication system that integrates GSM services and IP network resources to establish a low cost communication environment. In this paper, we discuss the design of signaling system in iNetwork system, and study the performance and efficiency of iNetwork by investigating the call setup time and mis-routing events. The resultant design has less routing stages than the original design of GSM, and it can avoid bandwidth wastages and enhances the utilization of network resources.
