Abstract

A protocol independent interface for processing, within a mobile device, protocol aiding data received at a call processor with a Global Positioning System (“GPS”) interface, where the protocol aiding data is produced according to a Geolocation Server Station protocol is disclosed. The protocol independent interface may include a means for receiving, at the GPS interface, the protocol aiding data received at the call processor, means for converting the received protocol aiding data to interface data that is transparent to the Geolocation Server Station protocol, and means for passing the interface data to a GPS module.

Claims

1. A partial almanac collection system in signal communication with a call processor, the partial almanac collection system comprising:

a global positioning system (“

GPS”

) module; and

a controller in signal communication with the GPS module and the call processor, the controller instructing the GPS module to collect piecewise almanac data in response to a request from the call processor.

2. The partial almanac collection system of claim 1, further including a memory unit in signal communication with the GPS module.

3. The partial almanac collection system of claim 2 wherein the GPS module is capable of processing received GPS signals.

4. The partial almanac collection system of claim 3, wherein the GPS module is capable of receiving a plurality of sub-sets of the GPS almanac.

5. The partial almanac collection system of claim 4, further including a memory unit in signal communication with the GPS module.

6. The partial almanac collection system of claim 5, wherein the controller is capable of storing the plurality of sub-sets of the GPS almanac into the memory unit.

7. The partial almanac collection system of claim 6, wherein the controller is capable of:

determining when the last sub-set of the plurality of sub-sets of the GPS almanac has been received; and

combining all the sub-sets of the plurality of sub-sets of the GPS almanac to create a full GPS almanac.

8. A partial almanac collection system in signal communication with a call processor, the partial almanac collection system comprising:

a global positioning system (“

GPS”

) module; and

means for instructing the GPS module to collect piecewise almanac data in response to a request from the call processor where the instructing means is in signal communication with the GPS module and the call processor.

9. The partial almanac collection system of claim 8, further including a memory unit in signal communication with the GPS module.

10. The partial almanac collection system of claim 9 wherein the GPS module is capable of processing received GPS signals.

11. The partial almanac collection system of claim 10, wherein the GPS module is capable of receiving a plurality of sub-sets of the GPS almanac.

12. The partial almanac collection system of claim 11, further including a memory unit in signal communication with the GPS module.

13. The partial almanac collection system of claim 12, wherein the means for instructing includes means for storing the plurality of sub-sets of the GPS almanac into the memory unit.

14. The partial almanac collection system of claim 13, wherein the means for instructing includes:

means for determining when the last sub-set of the plurality of sub-sets of the GPS almanac has been received; and

means for combining all the sub-sets of the plurality of sub-sets of the GPS almanac to create a full GPS almanac.
