UPDATING POSITION ASSIST DATA ON A MOBILE COMPUTING DEVICE
First Claim
1. A mobile computing device, comprising:
- a memory configured to store at least one type of position assist data, the memory being further configured to receive updated position assist data for the at least one type of position assist data and store the updated position assist data for the at least one type of position assist data;
a processing circuit configured to provide a position fix based on the position assist data, the processing circuit further configured to operate in an operating mode in which the at least one type of position assist data is updated in response to launching an application capable of requesting a position fix, the at least one type of position assist data comprising a type of position assist data selected from the group consisting of almanac data, ephemeris data, and mobile-station assist data; and
a transceiver configured for wireless communication.

Abstract
A mobile computing device comprises a memory, a processor and a transceiver. The memory is configured to store at least one type of position assist data. The processor is configured to provide a position fix based on the position assist data. The transceiver is configured for wireless communication. The memory is configured to store updated position assist data for the type of position assist data. The processor is operable in a first operating mode in which the type of position assist data is not updated and operable in a second operating mode in which the type of position assist data is updated in response to at least one triggering event.
