Abstract

A method of using radio signals transmitted for reception by mobile user equipment that includes receiving, with mobile user equipment (UE), radio signals having at least one format; monitoring, with the mobile user equipment, at least one property of the received radio signals; identifying a pattern in said monitored property or properties; and in response to identifying said pattern, triggering at least one action according to the identified pattern, and/or providing the UE with an indication of a location of the UE based at least part of the identified pattern.

Claims

1. A method of using radio signals transmitted for reception by mobile User Equipment (UE), the method comprising:

receiving, by the mobile UE, radio signals having at least one format;

monitoring, by the mobile UE, at least one property of the received radio signals;

identifying a pattern in said at least one property; and

in response to identifying said pattern, performing at least one of;

triggering at least one action according to the identified pattern; and

providing the mobile UE with a location of the mobile UE based at least in part on the identified pattern.

2. The method of claim 1, wherein the received radio signals comprise radio signals transmitted from at least one transmitter located at a terrestrial location.

3. The method of claim 1, wherein the received radio signals comprise signals transmitted from at least one Space Vehicle (SV).

4. The method of claim 1, wherein said pattern comprises at least one of a temporal pattern, a chronological pattern, a static pattern, an instantaneous pattern, and a dynamic pattern.

5. The method of claim 1, wherein said pattern comprises a change in at least one monitored property of at least one received radio signal.

6. The method of claim 1, wherein said pattern comprises an instantaneous combination of monitored properties of a plurality of different received radio signals.

7. The method of claim 1, wherein said at least one property comprises a received signal strength or power of a received radio signal.

8. The method of claim 1, wherein the at least one property comprises at least one of a Block Error Rate (BLER), a Bit Error Rate (BER), a Received Signal Strength Indicator (RSSI), a Common PIlot Channel Received Signal Code Power (CPICH RSCP), and a Space Vehicle (SV) power.

9. The method of claim 1, further comprising monitoring, by the mobile UE, information contained in the received radio signals.

10. The method of claim 9, wherein said identified pattern comprises a pattern in said information.

11. The method of claim 10, wherein said information comprises at least one of a neighboring cell ID list, a Base Station Identity Code (BSIC), a Subscriber Trunk Dialing (STD) code or region or area code, a Service Set IDentifier (SSID), a time and/or a date, a Global Positioning System (GPS) time of week, and a multipath indication.

12. The method of claim 1, wherein said identifying comprises processing results of said monitoring into a data format and comparing the results in said format with data stored in a memory.

13. The method of claim 12, further comprising using said results in said format to update the data.

14. The method of claim 1, wherein said action comprises at least one of:

providing from the mobile UE a signal for a user of the mobile UE;

changing a configuration of the mobile UE or of an external apparatus;

switching the mobile UE between different operational modes; and

switching at least one apparatus external to the mobile UE between different operational modes.

15. An apparatus for using radio signals transmitted for reception by mobile User Equipment (UE), the apparatus comprising:

a mobile UE for receiving radio signals having at least one format and monitoring at least one property of the radio signals;

a pattern identifier for identifying a pattern in said at least one property; and

a response processor for performing, in response to the pattern identification means identifying said pattern, at least one of;

triggering at least one action according to the identified pattern; and

providing the mobile UE with a location of the mobile UE based at least in part on the identified pattern.

16. A mobile User Equipment (UE) for using radio signals transmitted for reception by the mobile UE, the mobile UE comprising:

a receiver for receiving radio signals having at least one format;

a monitoring part for monitoring at least one property of the radio signals; and

a pattern identifier for identifying a pattern in said at least one property,

wherein the mobile UE is arranged to respond to the pattern identifier identifying said pattern by performing at least one of;

triggering at least one action according to the identified pattern; and

providing a location of the UE based at least in part on the identified pattern.
