1. A geolocation system, comprising:
- a geolocation server; and
a wireless communications device comprising a GPS receiver section, wherein the GPS receiver section can be selectively switched between a first mode and at least one other mode for determining a geolocation of the wireless communications device, wherein the first mode and the at least one other mode are selected from a group comprising a standalone mode, an autonomous mode, a network aided mode, and a network centric mode, and the wireless communications device can selectively send the determined geolocation of the wireless communications 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.

17. A method for determining the geoposition of a mobile device, comprising:
-
receiving at least one signal from at least one GPS satellite at the mobile device, wherein the mobile device can be selectively switched into a mode selected from a group comprising a first mode and at least one other mode, wherein the first mode and the at least one other mode are selected from a group comprising a standalone mode, an autonomous mode, a network aided mode, and a network centric mode;
determining the geolocation of the mobile device wherein the geolocation is determined using the selected mode, and wherein the determination of the geolocation occurs within a predetermined time period from the switching of the mobile device into the selected mode; and
selectively sending the determined geolocation of the mobile device to a geolocation server via a wireless network. - View Dependent Claims (18, 19)

20. A wireless communications device, comprising:
-
a call processing section for communicating with a wireless communications network; and
a GPS receiver section, wherein the GPS receiver section can be selectively switched between a first mode and at least one other mode for determining a geolocation of the wireless communications device, wherein the first mode and the at least one other mode are selected from a group comprising a standalone mode, an autonomous mode, and a network aided mode, and wherein the selective switching occurs within a predetermined time period from the determination of the geolocation of the wireless communications device, and the wireless communications device can selectively send the determined geolocation of the wireless communications device to the call processing section for transmission over the wireless communications network.
