METHOD FOR CONFIGURING SERVICE COMPOSITION IN OPEN COMMUNICATION NETWORK

摘要

PURPOSE: A method for configuring service composition in an open communication network is provided to easily configure a new service through an interface between service components and detailed standardization for connection procedures. CONSTITUTION: In case that a service provider who has received a service request from a user cannot provide the associated service to the user's terminal, looks for the third provider, acquires a list of services capable of service composition, and transfers a service composition request to the third provider(S601,S602). The third provider makes a request for the environment information of the user terminal and judges whether a service that the third provider provides is usable in the user terminal(S604). If it is judged that the user terminal can use a service that the third provider provides, the third provider accepts the composition request(S606). The third provider judges a composition type(S607) and creates a composition agent(S608). Then the third provider establishes the second session(S609).
