Context-Aware Web Services Orchestration for Multimedia Conference Process Management
نویسندگان
چکیده
Service oriented architecture is employed to cooperate with different software assets as long as they are wrapped up into web services. Under the architecture, the interoperation of telecom services and IT services is no longer an obstacle lying between the two domains. Besides, with the Web services orchestration technology, combining telecom services and IT services to rapidly develop and deploy new services can effectively improve software assets reusability. However, without context information, it is still hard to provide personalized services adapting to subscribers’ demands and market changes. In this paper, we bring forward context services to acquire context information and introduce context services into Web services orchestration. Taking multimedia conference business process management scenario as an example, we illustrate that context information acquired from context services can assist to provide personalized services to rapidly adapt subscribers’ demands and market changes.
