Abstract:
1. A method of determining a location of a multi-Subscriber Identification Module (SIM) mobile terminal having at least first and second SIMs mounted therein, the method comprising: ascertaining whether the first and second SIMs are associated with a common mobile network or with different mobile networks, and if associated with different mobile networks: determining a first location based on a location of at least one first base station in a first network associated with the first SIM and receive signal strength of a signal transmitted by the at least one first base station; determining a second location based on a location of at least one second base station in a second network associated with the second SIM and receive signal strength of a signal transmitted by the at least one second base station; and estimating the location of the multi-SIM mobile terminal from the first and second locations; and if the first and second SIMs are associated with the common network, estimating the location of the multi-SIM mobile terminal based on receive signal strength of a signal transmitted by at least one base station in the common network and a location of the at least one base station in the common network.
