Services, Enablers and Architectures: Definition of a connected Web 2.0 / Telco Service Broker to enable new flexible Service Exposure Models

Modern telecommunication networks and classical roles of operators are subject to fundamental change. Many network operators are currently seeking for new sources to generate revenue by exposing network capabilities to 3rd party service providers. At the same time we can observe that applications on the World Wide Web (WWW) are becoming more mature in terms of the definition of APIs that are offered towards other services. The combinations of those services are commonly referred to as Web 2.0 mash-ups. This report describes our approach to include Next Generation Networks (NGN)-based telecommunications application enabler into Web 2.0 mash-ups by defining a policy-based service broker that mediates between 3 party applications and service enablers and a JavaScriptbased service exposure API that allows easy and straight forward integration of telecommunications enablers into such mash-ups. The orchestration of several service enablers into one complex service for further exposure is anticipated.
