Dynamic compensation for wireless device location determination

摘要

Determining a location estimate of a wireless communications device can depend on the dynamic and/or static state of the device. Compensation processing is applied to a location estimate (or to information from which such an estimate is derived, in use) if required, given the dynamic and/or static state of the device.

主权项

1. A wireless communications device operable to determine a location estimate representative of a location of the device with respect to a location reference frame, the device comprising:
a compensation determining unit determining a requirement for compensation with regard to dynamic and/or static state of the device, and operable to determine a compensation to be applied if required; a compensation applying unit operable to apply, if required, a determined compensation to derive a location estimate compensated for dynamic and/or static state of the device; a signal detection unit operable to detect the presence of detectable signals from location reference frame defining devices, and operable to detect signal strength of detected signals; the device being operable to send, to a location determining device, a signal bearing information on signals detected by said wireless communications device, for said location determining device to determine a location estimate for location of said device, said wireless communications device being operable to receive a signal bearing information on a location estimate determined by said location determining device.
