Abstract

A method of tracing a mobile wireless communication device geographic location in a wireless telecommunications network, and a method of notifying a mobile wireless communication device tracing unit of a mobile wireless communication device geographic location in a wireless telecommunications network, and devices and computer program products operable to perform said methods. The method of tracing comprises: receiving notification of an identity of a communication device of interest; initiating paging of the communication device of interest and requesting an indication of geographic location of the communication device of interest; monitoring for receipt of an indication of geographic location and, on receipt of the indication of geographic location, determining the geographic location of the communication device of interest. The method of notifying comprises: assessing whether predetermined trace trigger criteria have been met; and, if so, determining a geographic location of the mobile wireless communication device; establishing a communication link with the tracing unit; and transmitting an indication of the determined geographic location to the mobile device tracing unit. Aspects provide wireless network initiated methods to track lost, stolen or missing mobile communication devices, such a smart-phones or tablets.

Claims

1. A method of notifying a mobile wireless communication device tracing unit of a mobile wireless communication device geographic location in a wireless telecommunications network, said method comprising:

assessing whether predetermined trace trigger criteria have been met;

and, if so, determining a geographic location of said mobile wireless communication device;

establishing a communication link with said tracing unit; and

transmitting an indication of said determined geographic location to said mobile device tracing unit.

2. A method according to claim 1, wherein said predetermined trace trigger criteria comprises:

reception of a request, from said wireless communication device tracing unit, for an indication of geographic location of said communication device.

3. A method according to claim 1, wherein said predetermined trace trigger criteria comprises:

determining whether available battery power at said mobile communication device has passed a predetermined threshold indicative of likely battery power failure.

4. A method according to claim 1, wherein said predetermined trace trigger criteria comprises:

determining whether an unauthorised power off procedure has been initiated.

5. A method according to claim 1, wherein said predetermined trace trigger comprises:

determining whether an unauthorised SIM removal procedure has been initiated.

6. A method according to claim 1, wherein authorised SIM removal or power off procedures require input of a user identity code to said mobile wireless communication device.

7. A method according to claim 1, further comprising encoding said indication of determined geographic location as a decimal indication of latitude and longitude and transmitting said decimal indication using dual tone multi-frequency signalling techniques.

8. A method according to claim 1, further comprising preventing initiation of a power off procedure in the event that predetermined trace trigger criteria have been met.

15. A computer program product operable, when executed on a computer, to perform the method of claim 1.

9. A mobile wireless communication device operable to notify a mobile wireless communication device tracing unit of its geographic location in a wireless telecommunications network, said mobile wireless communication device comprising:

assessment logic operable to assess whether predetermined trace trigger criteria have been met;

location determining logic operable to determine a geographic location of said mobile wireless communication device if said predetermined trace trigger criteria have been met;

communication logic operable to establish a communication link with said tracing unit;

and transmit an indication of said determined geographic location to said mobile device tracing unit.

10. A method of tracing a mobile wireless communication device geographic location in a wireless telecommunications network, said method comprising:

receiving notification of an identity of a communication device of interest;

initiating paging of said communication device of interest and requesting an indication of geographic location of said communication device of interest;

monitoring for receipt of an indication of geographic location and, on receipt of said indication of geographic location, determining said geographic location of said communication device of interest.

11. A method of tracing a mobile wireless communication device according to claim 10, wherein said indication of geographic location comprises an indication of a latitude and longitude of said communication device of interest comprising a decimal indication of latitude and longitude encoded using dual tone multi-frequency signalling techniques.

12. A method of tracing a mobile wireless communication device according to claim 10, wherein determining of said geographic location of said communication device of interest comprises utilising an online mapping service application to generate a map indicative of said geographic location.

13. A method of tracing a mobile wireless communication device according to claim 10, further comprising notifying a user of said determined geographic location.

16. A computer program product operable, when executed on a computer, to perform the method of claim 10.

14. A mobile device tracing unit operable to trace a mobile wireless communication device geographic location in a wireless telecommunications network, said device tracing unit comprising:

reception logic operable to receive notification of an identity of a communication device of interest;

paging logic operable to initiate paging of said communication device of interest and request an indication of geographic location of said communication device of interest;

monitoring logic operable to monitor for receipt of an indication of geographic location and,

determination logic operable, on receipt of said indication of geographic location, to determine said geographic location of said communication device of interest.
