In a method for providing location-based information over a network, a plurality of GPS reference data sets, corresponding to a plurality of respective local areas, are acquired at intervals such that each GPS reference data set is updated on a continuous basis. A plurality of aiding data sets are generated at intervals based on the respective GPS data sets, whereby each aiding data set is updated on a continuous basis. The generated aiding data sets are stored at intervals on a data-storing network server, whereby updated aiding data sets are available on a continuous basis for access by a requesting entity via communication with the data-storing network server.

System and method for providing location based services over a network

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.

Aided location communication system

A system is described that utilizes an imager in a wireless device () in a wireless network () and transmits a digital image to a service center () that assists in identifying the location of the wireless device () within a cell site ().

Method and system for sending location coded images over a wireless network

A system is described that utilizes an imager in a wireless device in a wireless network and tags a digital image with positioning data.

Method and system for sending location coded images

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.

Multi-mode global positioning system for use with wireless networks

The present invention discloses a method, system, and apparatus for sharing circuitry within mobile GPS and Bluetooth receivers. By selectively combining the downconversion, processing, and control sections, lower power dissipation can be achieved, along with lower form factors and lower manufacturing costs.
