Provision of location dependent services without revealing the user identity via a mobile telecommunications network
First Claim
1. A method by which a service provider provides a service to a user in a mobile telecommunications network in response to a request for the service by that user, in which the network generates a request signal in response to the a user request, the network transmits the request signal to the service provider, and the service provider provides the service to the user via the network and using the request signal, the request signal including identity information which identifies the user to the network but provides no information to the service provider which enables the service provider to directly access the user, wherein the request signal includes data allowing the request signal to be distinguished by the service provider from request signals relating to other requests, and in that the request signal is only effective for the service provider for a length of time which is dependent on the a length of time for providing the service.

Abstract
Application service providers (ASP1, ASP2 . . . ) are linked to a mobile telecommunications network (N), such as a cellular telecommunications network, for providing services such as information-providing services to users (MS1, MS2, MS3 . . . ) in the network. For example, one service provider (ASP1) may, on request from a user, provide the address of or directions to the user'"'"'s nearest pizza outlet. The user'"'"'s request is intercepted by the network which generates a “user tag” identifying the user, the service provider to whom the request is directed, and the time and date of the request. The network stores the information in the user tag, encodes it and transmits it to the service provider in a form from which the service provider is unable to access the user or obtain the user'"'"'s identity. The service provider then requests the current location of the user from the network using the user tag to identify the user to the network. The network transmits the user'"'"'s location to the service provider in association with the user tag and the service provider responds by transmitting back to the network the information required by the user (the address of or directions to the user'"'"'s nearest pizza outlet), again in association with the user tag. The network passes the information to the user. Finally, the service provider requests the network to levy a charge against the user, again using the user tag so that the network can identify the particular user. In this way, information identifying the user is never provided to the service provider who cannot therefore directly access the user either during the session or subsequently. The user tag may have a predetermined short lifetime to provide further security.
