摘要：
Next generation telecommunication network operators securely opening up their network capabilities and services to third party service providers require flexible service delivery platforms. Policy based service exposure, service discovery and service composition mechanisms are required to offer chargeable services and service building blocks to external entities in a customizable way. Based on research and developments conducted while prototyping solutions for the Open SOA Telco Playground, a unique IMS based NGN testbed for realizing SOA based NGN service delivery platforms, this work proposes the eXtended POlicy based, Semantically enabled sErvice bRoker (XPOSER). XPOSER provides novel NGN service exposition mechanisms. It enables intent-based NGN service discovery and allows for user-centric, automated service composition. Utilizing SOA based Operation Support Systems this work explains requirements and solutions for dynamically managing NGN service compositions by tightly linking service creation, service fulfillment and service assurance mechanisms already at service composition time.
