A mobile type service provider terminal registers a service providing area to a presence management server before a service starts. The presence management server creates a status management table of the mobile type service provider terminal. When the presence of the mobile type service provider terminal is detected in an area, the terminal registers information contents, which are delivered to subscribers, to an information delivery server. When the information delivery server stores the registered information contents to an information contents database and completes the creation of an information providing table, it notifies a service control server of the information. The service control server creates a message with reference to the information notified from the information delivery server and delivers it to the subscribers.
