Wireless mobile terminal using sensors for controlling autonomous and assisted GPS modes
First Claim
1. A mobile terminal capable of operating in a plurality of position tracking modes comprising:
- a Global Positioning System (GPS) unit capable of receiving GPS signals from a plurality of GPS satellites, wherein the GPS unit is further capable of operating in
1) a device autonomous fix (DAF) mode,
2) a server-computed assisted fix (SCAF) mode, and
3) a device-computed assisted fix (DCAF) mode;
a network transceiver capable of communicating with at least one terrestrial wireless network;
a controller capable of controlling the operating mode of the GPS unit, wherein the controller is capable of transitioning the GPS unit between the DAF mode, the SCAF mode, and the DCAF mode; and
at least one sensor associated with the mobile terminal capable of generating an interrupt signal, wherein the controller receives the interrupt signal and in response thereto causes the GPS unit to operate in one of the DAF mode, the SCAF mode, and the DCAF mode.

Abstract
A mobile terminal that operates in a plurality of position tracking modes. The mobile terminal comprises a Global Positioning System (GPS) unit for receiving GPS signals from a plurality of GPS satellites. The GPS unit can operate in i) a device autonomous fix (DAF) mode, ii) a server-computed assisted fix (SCAF) mode, and iii) a device-computed assisted fix (DCAF) mode. The mobile station also comprises a network transceiver for communicating with at least one terrestrial wireless network and a controller for controlling the operating mode of the GPS unit. The controller transitions the GPS unit between the DAF mode, the SCAF mode, and the DCAF mode. The controller receives an interrupt signal from at least one sensor and, in response, causes the GPS unit to operate in one of the DAF mode, the SCAF mode, and the DCAF mode.
