Hi skunks/skunkettes, in line with an earlier discussion on this being a technical forum... May i call upon your help without monetary gains taking an upper hand???? please :) i want to try and create an application for triangulating a mobile phone. i am at a loss on where to start....really!!! so i throw it to the floor. ******************* In a GSM network with than one vendor a proprietary software is normally supplied to handle their equipment including the BTS. Mobile phones however send Measurement reports which are standardized. these reports contain the following, 1. signal level of 6 best neignbours 2. signal quality\level of serving cell 3. the BTS can determine the Timing Advance of the Mobile(The distance (usually a range) the mobile is from the bts) as well as serving cell (Sector) Now, with just the Timing Advance(TA) and Serving cell, i can tell the general direction of a user. however i would like to use the other measurements to narrow down the location ************************* The significance of this is that it a network can track a phone that does not have a GPS. it would make phone thefts less bothersome among things. If guys discuss it for a bit, i'm sure i'll find my footing, regards, Hellen
