Integrated service creation environment for open network services

The service creation scheme is changing with the advent of open network service architecture for next-generation network. New requirements should be considered for IT domain developers to create telecom and Internet combined services more easily. This paper describes an integrated service creation environment (SCE) to reflect the trend of network evolution toward an open network environment. The SCE provides multiple service programming tools to support various users' background, a mash-up toolkit for IT domain, a simulation-based validation tool, a run-time adaptation tool, and a personalized service provisioning environment. Several example services were implemented to verify the features of an integrated SCE. Our approach is very promising because it supports various requirements and background of service developers on the full service creation process. Furthermore, it provides a means for personalized service creation driven by end-user, which is a new trend of future network.
