发明名称 Information providing system
摘要 An information providing system capable of effectively offering a desired service. In this system, when the user uses a portable terminal to issue a request for a desired service toward a base station, a given server receives this service request through a simplified portable telephone system network and then transmits it, for example, to a client which can respond to the service request of the user. The client sends reply information through the server to the portable terminal. The user makes the service request to the client when the user decides, on the basis of the reply information, that the desired service is attainable from the client.
