METHOD AND SYSTEM TO PROVIDE GSM / PCS SUBSIDIARIES DEPENDENT SERVICES OF THE PLACE

摘要

Registering, ordering and using location- and user-specific services in a client-server environment having mobile equipment operating within wireless communication cells. The client is typically a WAP-enabled GSM phone logged onto a GSM 900/1800 or PCS 1900 cellular telecommunications network. The server may be either a combination WAP gateway and standard Web server or a WAP application server. The server may be interlinked via the Internet and may have access to a database system. The database stores geographical information required for a location-based service, such as the level of rooms in a building, aisles in a store, or gates at an airport. The database also can include service-specific logic that is executed in response to a client demands. The client exploits location data that is stored on an SIM card attached to the mobile equipment. Forwarding the current location area code or cell identification together with the subscriber's MSISDN to a WAP application can trigger the server to execute the application logic. The user may then select a more precise location and a service attached to that location. By using push technology, the server may deliver information to the client without receiving an information request from the client. IMAGE
