Abstract

A kit and method of investigating the location of a portable telecommunications device used in making a call, includes obtaining information on the position of the receiver involved in the call. A location is surveyed by visiting the location and establishing the receiver a portable telecommunications device would use from that location. The method also compares the receiver involved in the call with the receiver that would be used from the surveyed location.

Claims

1. A method of investigating the location of a portable telecommunications device used in making a call, the method comprising:

obtaining information on the position of the receiver involved in the call;

surveying a location by visiting the location and establishing the receiver a portable telecommunications device would use from that location;

comparing the receiver involved in the call with the receiver that would be used from the surveyed location.

2. A method according to claim 1, wherein the method includes establishing the locations for which the receiver involved in the call would be the receiver by the portable telecommunications device.

3. A method according to claim 1, wherein the location surveyed is the location which is a claimed location of use and the method includes establishing whether the receiver involved in the call is the same as the receiver that would be used from a location in respect of the claimed location of use.

4. A method according to claim 1, wherein the device is a mobile phone and/or is a device capable of accessing the Internet, such as a portable computer.

5. A method according to claim 1, wherein the call involves voice transmission and/or data transmission and/or short message service transmission and/or transmission of a text message and/or the device'"'"'s response to an interrogation signal from a receiver.

6. A method according to claim 1, wherein the method investigates a plurality of locations so as to determine the extent of an area for which the receiver that would be used applies.

7. A method according to any claim 1, wherein the method is performed within a range of time around an equivalent time of day to the time of the call, the range being the time of the call plus or minus 1 hour.

8. A method according to claim 1, wherein the method is performed on an equivalent day of the week as the call.

9. A method according to claim 1, wherein the method is performed with the network, or at least the part thereof in the vicinity, of which the receiver is a part under one or more operating conditions which are the same as at the time of the call.

10. A method according to claim 9, wherein the conditions are the receivers available for use and/or the level of use on one or more of the receivers locally and/or the technology operated by the network and/or that the conditions are the same by virtue of, one or more of, the time of day and/or the day of the week and/or natural and/or artificial traffic on the network and/or enablement and/or disablement of receivers in the network and/or reinstatement of the technology used on that part of the network at that time.

11. A kit, the kit comprising:

a detector for establishing the receiver a portable telecommunications device would use from a location;

a detector for establishing the position of the location;

a data recording unit for data including the receiver that would be used from a location and the position of the location.
