Abstract
In an information providing system, a user inputs desired mobile ID number to a client terminal. The client terminal transmits a request for location information on the mobile station including the mobile ID number to a location server via a location information server. The location server transmits a request for object movement information corresponding to the mobile station to an object information server. The location information server obtains the information from a traffic control device. Location information on the mobile station obtained by the location information server is transmitted to the terminal.
