METHOD FOR DYNAMICALLY PROTECTING SERVICE IN COMMUNICATION SYSTEM

摘要

PURPOSE: A method for dynamically protecting a service in a communication system is provided to embed an agent in the service to dynamically control the service, so as to prevent illegal use of the service. CONSTITUTION: If an agent delivers an ID to an agent server through the network(201), the agent server authenticates the ID based on a database(202) and produces a service list assigned to the ID(203), then delivers the service list to the agent(204). The agent receives a service start request message from a sub-service while waiting executing messages of each sub-service(205), and decides whether a corresponding service is available based on the service list(206). If available, the agent generates a service start permission message(207) and delivers the generated message to the corresponding sub-service(208), then performs the corresponding service in the sub-service(209). If the service is unavailable in the step 206, the agent generates a service end message(210) and delivers the generated message to the sub-service(211). The sub-service outputs a service start error message(212). The agent notifies service end to the agent server(213). And the agent server processes the service end(214) and stores a processed result in the database.
