Abstract
A method of enabling navigation from a headset is disclosed. The method generally includes the steps of (A) receiving a first signal transmitted by a device to the headset through a wireless personal area network, the first signal carrying assist data transmitted by an Assisted Global Positioning System server, (B) receiving a plurality of navigation signals transmitted by a navigation system to the headset and (C) calculating a current position of the headset at a first time using the assist data to lock onto the navigation signals.

A method of enabling navigation from a headset, comprising the steps of:
- (A) receiving a first signal transmitted by a device to said headset through a wireless personal area network, said first signal carrying assist data transmitted by an Assisted Global Positioning System server;
- (B) receiving a plurality of navigation signals transmitted by a navigation system to said headset;
- and
- (C) calculating a current position of said headset at a first time using said assist data to lock onto said navigation signals.
A headset comprising:
- a network circuit configured to receive a first signal transmitted by a device through a wireless personal area network, said first signal carrying assist data transmitted by an Assisted Global Positioning System server;
- and
- a navigation circuit configured to (i) receive a plurality of navigation signals transmitted by a navigation system and (ii) calculate a current position of said headset at a first time using said assist data to lock onto said navigation signals.
A method of enabling navigation in a headset, comprising the steps of:
- (A) receiving a first signal carrying assist data transmitted by an Assisted Global Positioning System server through a cellular network to a device;
- (B) transmitting a second signal carrying said assist data from said device to said headset through a personal area network;
- (C) receiving a third signal carrying a current position transmitted by said headset through said personal area network to said device;
- and
- (D) utilizing said current position in a location-based service operating in said device.
A system comprising:
- a receiver module in a device configured to receive a first signal carrying assist data transmitted by an Assisted Global Positioning System server through a cellular network to said device;
- a network module in said device configured to transmit a second signal carrying said assist data from said device to a headset through a personal area network and (ii) receive a third signal carrying a current position transmitted by said headset through said personal area network to said device;
- and
- a service module in said device configured to utilize said current position in a location-based service operating in said device.
