Provision of position information in cellular network data transmission
First Claim
1. A method of communicating a request for a service from a mobile telecommunications device to said service via a cellular wireless network including a plurality of transceiver stations, each located in a corresponding cell, comprising the steps of:
- establishing a wireless connection between said mobile device and one of said transceivers;
transmitting a request for the service from the mobile device to the transceiver;
determining the position of said mobile device;
estimating the accuracy of said position determination;
transmitting said request through the network and onward to the service, said transmitted request including position and accuracy information about the mobile device.

Abstract
A cellular telecommunications system comprises a plurality of transceiver stations forming a network for transmission of signals between a mobile communications device and an internet based server hosting an application which is dependent on the position of the mobile device. The position of the mobile device is provided to the application as part of the initial request for the service from the device, thus avoiding the need for multiple flows of information. The position may be based simply on the known location of the transceiver station with which the device establishes wireless connection, with directional or signal strength range information added, if available. Alternatively, the position may be estimated more accurately from the signal received at multiple transceiver stations. In either case an accuracy estimate can be added to the determined position.

32. A cellular telecommunications system comprising a plurality of transceiver stations forming a network for transmission of signals from or to any of a plurality of mobile communication devices to an internet based server;
-
location service means, responsive to a request from a mobile communications device for a service located on such a server, to estimate the position of a mobile device, said position estimate being based on the position of the one of said transceiver stations receiving the strongest signal from said device, from a table of stored transceiver positions; and
means for adding said position estimate to said request for transmission to said server. - View Dependent Claims (33, 34, 35, 36)
