Method and System for Providing Enhanced Location Based Information for Wireless Handsets
First Claim
1. A method of determining a location of a mobile device, comprising:
- determining an approximate location of the mobile device;
grouping the mobile device with a wireless transceiver in proximity to the mobile device to form a communication group;
sending the determined approximate location of the mobile device to the wireless transceiver;
receiving on the mobile device location information from the wireless transceiver; and
determining a more precise location of the mobile device based on the location information received from the wireless transceiver.

Abstract
Methods, devices and systems for generating enhanced location information on or about a mobile device may include hybrid lateration and/or trilateration solutions in which the mobile device performs location determination calculations with or without the aid or support of network components or global positioning systems (GPS). Mobile devices may automatically form groups based on proximity and/or may be grouped together via a network server. Mobile devices in a group may share computed location information and/or information collected from internal sensors with other grouped mobile devices. Information shared between grouped mobile devices may be used to enhance the location information computed on each mobile device. For example, each mobile device may supplement and/or augment previously computed location information based on the received location information and/or relative positions of other mobile devices in the same group. Each mobile device may also utilize local sensors to further enhance their location information.
