Optimizing performance of multiple location based service applications that are running either alone or simultaneously on a wireless device

A mobile device, comprising:

• a transceiver for wireless communication via a mobile communication network;
• a location engine for determining a fix for a location of the mobile device, wherein the location engine is controllable to determine a location fix using a plurality of different fix modes;
• a queue for holding requests for location fix for the mobile device from one or more applications;
• and
• a location engine driver configured to:
• (a) run the location engine in a first fix mode to obtain a fix on the location of the mobile device for a response to a first request out of the queue, based on information in the first request;
• (b) based at least in part on the first fix mode, change information in a second request in the queue to change the fix mode with respect to the second request, before running the location engine responsive to the second request.

An article of manufacture, comprising:

• a non-transitory computer readable storage medium;
• and
• programming embodied in said medium for execution by a processor of a mobile device having a location engine to determine a fix for a location of the mobile device using a plurality of different fix modes,
• wherein the programming configures the processor to implement a location engine driver in the mobile device that is capable of performing functions, including functions to:
• hold requests for location fix for the mobile device from one or more applications in a queue in the mobile device;
• run the location engine of the mobile device in a first fix mode to obtain a fix on the location of the mobile device for a response to a first request output from the queue;
• and
• based at least in part on the first fix mode, change information in a second request in the queue to change the fix mode with respect to the second request, before running the location engine responsive to the second request.
