A SIP Based Next Generation Services Platform

Abstract

Mobile network operators aims are offering new services to be competitive in the telecommunications market. However, the migration cost towards the third generation (3G) network is so high. This paper presents a proposal to offer a next generation services platform based on session initiation protocol (SIP). This solution is easy to implement and its cost is relatively low. Our solution takes into account the IP multimedia subssytem (IMS) service architecture specification proposed by the third generation partnership project (3GPP) providing ubiquitous characteristics for mobile users. In this way, our proposal becomes as a tool to allow an easy transition from 2.5 to 3rd generation networks.
