Aided location communication system
First Claim
1. An Aided Location Communication System (“
- ALCS”
), comprising;
a geolocation server; and
an Aided Location Communication Device (“
ALCD”
) including a communication section in signal communication with the geolocation server, and a position-determination section having a GPS-engine, wherein the communication section is capable of selectively switching between a first position-determination mode for determining a geolocation of the ALCD and a second position-determination mode for determining the geolocation of the ALCD.

Abstract
An Aided Location Communication System (“ALCS”) is described that may include a geolocation server and a wireless communication device having a GPS section where the GPS receiver section is capable of being selectively switched between a standalone mode and at least one other mode for determining a geolocation of the wireless communications device. An Aided Location Communication Device (“ALCD”) is also described. The ALCD includes a position-determination section having a GPS receiver and a communication section where the position-determination section is selectively switchable between a GPS-standalone mode and at least one other mode for determining a geolocation of the ALCD.
