Abstract
Method and apparatus for processing position information in a mobile device is described. In one example, a request for a position to be computed within a predefined period of time is received. A plurality of positions is calculated within the predefined period of time. At least one of the plurality of positions is cached in a position cache. Accuracy data is derived with respect to at least one of the plurality of positions. A best position stored in the position cache is identified in response to the accuracy data. The best position may be sent to a server in communication with the mobile device.
Claims22
A method of processing position information in a mobile device, comprising:
- receiving a request for a position to be computed within a predefined period of time;
- computing a best position and a corresponding indicia of accuracy within said predefined period of time;
- comparing said indicia of accuracy to a threshold;
- retaining said best position in a cache in response to said indicia of accuracy satisfying said threshold;
- searching said cache for a previously retained position having a best accuracy in response to said indicia of accuracy failing said threshold;
- and
- sending an indication of no accurate position to a server in response to no previously retained position being stored in said cache.

- computing a best position and a corresponding indicia of accuracy within said predefined period of time;
- comparing said indicia of accuracy to a threshold;
- retaining said best position in a cache in response to said indicia of accuracy satisfying said threshold;
- identifying a previously retained position in said cache having a best accuracy in response to said indicia of accuracy failing said threshold;
- comparing said best accuracy of said previously retained position to a second threshold;
- and
- sending said previously retained position to a server in communication with said mobile device in response to said best accuracy satisfying said second threshold.
