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

摘要

Requests for location fix for a mobile device are received from one or more Location Based Service (LBS) applications. The received requests are queued in a First In First Out (FIFO) queue in the mobile device. Based on information in a first request out of the FIFO queue, the mobile device runs a location engine in a first fix mode to obtain a fix on the location of the mobile device for a response to the first request. While the location engine is running to obtain the fix for the response to the first request, the mobile device analyzes information in a second request in the FIFO queue, to determine a second fix mode for response to the second request. Based on a comparison of the second fix mode to the first fix mode, the mobile device may change the information in the second request to correspond to the first fix mode, before output of the second request from the FIFO queue to the location engine.
