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 protocol independent interface for processing, within a mobile device, protocol aiding data received at a call processor with a Global Positioning (“

GPS”

) interface, where the protocol aiding data is produced according to a Geolocation Server Station protocol, the protocol independent interface comprising;

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.

2. The protocol independent interface of claim 1, further including packing the interface data into a message format before passing the interface data to the GPS module.

3. The protocol independent interface of claim 2, wherein the call processor receives the protocol aiding data from a base station.

4. The protocol interface of claim 3, wherein a Geolocation Server Station produces the aiding data.

5. The protocol independent interface of claim 4, wherein the Geolocation Server Station utilizes a Code Division Multiple Access (“

CDMA”

) protocol to produce the protocol aiding data.

6. The protocol independent interface of claim 5, wherein the protocol is IS-801.

7. A protocol independent interface for processing, within a mobile device, protocol aiding data received at a call processor where the protocol aiding data is produced according to a Geolocation server Station protocol, the protocol independent interface comprising:

an air-interface protocol to GPS module interface converter;

a serial link in signal communication between the call processor and Global Positioning System (“

GPS”

) module; and

a GPS module data structure.

8. 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, the protocol independent interface comprising;

means for receiving, at the GPS interface, the protocol aiding data received at the call processor;

means for passing the interface data to a GPS module; and

means for converting the received protocol aiding data to interface data that is transparent to the Geolocation Server Station protocol.
