Multi-mode global positioning system for use with wireless networks
First Claim
1. A geolocation system, comprising:
- a geolocation server, wherein the geolocation server receives at least one signal from at least one GPS satellite; and
a wireless communications device, comprising a GPS receiver section, wherein the GPS receiver can be selectively switched between a standalone mode and at least one other mode for determining a geolocation of the wireless communications device, and the wireless communication device can selectively send the determined geolocation of the wireless communication device to the geolocation server.

Abstract
The present invention discloses a GPS system that can operate in different modes depending on the network facilities and bandwidth available, the GPS information that can be acquired, or user or system requirements. The modes comprise standalone mode, where a mobile communications device computes the position of the device, an autonomous mode, where the mobile communications device transmits the computed position to a server, application, or PSAP in a communications network, a network aided mode, where the network aides the mobile communications device in determining the position of the device, a network based mode, and other modes.
