Emerging Web and Telecom services: Prototyping FMC services based on IMS and Web 2.0 for a mobile operator

Modern telecommunication networks and classical roles of Operators are subject to fundamental changes. Standardization bodies and the industry are specifying and integrating Next Generation Network (NGN) infrastructures and NGN services based on an all-IP paradigm. The IETF, ETSI, 3GPP, 3GPP2 and OMA are working on technological issues to enable services using Internet technology and Service Orientated Architectures (SOA). This paper reports about two services, a single network agnostic Voicemail application and Network Stored Presence Enabled Address Book for legacy as well as emerging IP networks that have been prototyped for a major European mobile operator as part of a FMC Technology Experience Centre. It focuses on the use of standardized telecommunications architectures and APIs to glue emerging telecommunication architectures with the Internet and vice versa. Furthermore this paper presents our experiences during the development and testing process.
