Foreword
The telecommunications industry is undergoing a fundamental change and the catalyst for this change is the business models and technologies of the Internet. The ubiquitous use of the Internet Protocol suite (IP) for voice, data, media and entertainment purposes, is driving the convergence of industries, services, networks and business models.
Network convergence is the route through which operators facilitate better access to end-user services and applications. IP provides a common foundation offering end-users seamless access to any service, any time, anywhere, and with any device. Full convergence is driven by enabling technologies such as HTTP/SIP, IPv6, VoIP, and the deployment of wireless broadband technologies such as WLAN, CDMA2000, and UMTS/HSPA.
The 3rd Generation Partnership Projects (3GPP and 3GPP2) have taken these developments into account whilst designing the IP-based Multimedia System (IMS). IMS is an overlay service provisioning platform through which telecommunications operators can utilise Internet technologies to their greatest advantage. It operates across fixed and mobile access technologies including WLAN, UMTS/HSPA, and DSL, along with many others.
The telecommunications industry has high expectations for IMS. This technology offers the prospect of new value chains and business models for operators on the one side, and the increase of the end-user experience through converged and blended services on the other.
