Service Delivery Platform Architecture for the Next-Generation Network

This paper describes an advanced service delivery platform (SDP) that is expected to be used in the Next Generation Network (NGN). To meet diverse demands from NGN customers, it is very effective to integrate state of the art technologies beyond the boundaries of technical domains, such as the telecommunication, enterprise, and Internet fields, to enrich services and mash-up simple service elements into unlooked-for values. We use the service oriented architecture (SOA) concept as the basis and extend it to ease the creation of customised or personalised services. Context-aware dynamic binding of service components, finer-grained SIP call handling, and execution control for guaranteeing the service level agreement are main features of our platform. This is expected to play an important role in the NGN or ubiquitous communication environments.
