Abstract

A method of inferring a state of activity of a carrier of a mobile communication device, the method comprising

• • a. monitoring a parameter of a transmitter serving the mobile communication device and of a plurality of neighbouring transmitters;
  • b. acquiring data relating to the monitored parameter of the serving transmitter and the neighbouring transmitters during a time window;
  • c. processing the acquired data to generate a time window parameter associated with the time window;
  • d. repeating steps b and c for one or more further time windows; and
  • e. inferring the state of activity of the carrier of the mobile communication device from the time window parameters generated in steps b and c.

Claims

14. A method of calibrating an algorithm for inferring a state of activity of a carrier of a mobile communication device, the method comprising

a. collecting data relating to a time window parameter associated with a transmitter serving the mobile communication device and a plurality of neighbouring transmitters;

b. grouping the collected data into a plurality of sets, each set reflecting a different state of activity;

c. calculating a mean for each set; and

d. using the calculated means to calibrate the algorithm.

15. A method according to claim 14 wherein the collected data are grouped automatically into the plurality of sets.

16. A method according to claim 14 further comprising collecting information relating to a state of activity of the carrier of the mobile communication device during collection of the data relating to the time window parameter, wherein the collected data are grouped according to the information so collected.

17. A method according to claim 16 wherein the information relating to the state of activity of the carrier comprises the movement speed of the carrier, each state of activity being associated with a range of movement speeds.

18. A method according to claim 16 wherein the information relating to the state of activity of the carrier comprises an identifier associated with the serving transmitter or the plurality of neighbouring transmitters.

19. A method according to claim 14 wherein the time window parameter comprises a total signal strength fluctuation of the serving cell and the neighbouring cells during a time window.

20. A method according to claim 14 wherein the time window parameter comprises a number indicative of the number of separate transmitter identifiers appearing on a list maintained by the mobile communication device during a time window.

21. A method according to claim 19 further comprising collecting data relating to a further time window parameter associated with the serving transmitter and the plurality of neighbouring transmitters.

22. A method according to claim 21 wherein the further time window parameter comprises a number indicative of the number of separate transmitter identifiers appearing on a list maintained by the mobile communication device during a time window.

24. A program for causing a processor system to perform the method of claim 14.

23-1. A mobile telephone comprising an apparatus according to claim 23.

25. A method of selecting a calibration setting for calibrating an algorithm for inferring a state of activity of a carrier of a mobile communication device, the selection method comprising observing a parameter of a transmitter serving a mobile communication device over a time window and using the parameter so observed to select a calibration setting from a pre-populated list of calibrations settings.

26. A method according to claim 25 further comprising inferring from the observed parameter an environment type and selecting a calibration setting appropriate to the environment type from the pre-populated list of calibration settings.
