Systems and Methods for Location Assistance with Personal Area Network Devices

摘要

Implementations relate to systems and methods for location assistance using devices (104) in a personal area network (PAN). In one scenario, a user may use two separate location-enabled devices, such as a wearable personal device (102) and a cellular telephone device (104). In cases, one of those devices may have reached a higher or farther-developed state in terms of generating or storing location information (108) for the user's current position, as compared to the opposite device. This can take place, for instance, when the first (e.g. wearable) device (102) is first turned on. The two devices use platforms and techniques to exchange location information and carry out GPS or other operations to furnish the device that is lagging in position processing progress with assistance which will speed up or otherwise enhance the position fix for that device.

主权项

1. A method of generating position data, comprising:
initiating a first positioning process, on a first device, having one of a hot location processing state or a non-hot location processing state, wherein the first device has a personal area network connection to a second device with a second positioning process; when the location processing state of the first positioning process is non-hot,
initiating a personal area network data exchange between the first device and the second device to request location information from the second device, in addition to initiating the first positioning process; andgenerating position information for the first device via—
the first positioning process augmented by any location information received from the second device, when the location processing state of the first positioning process is non-hot.
