Method and System for Providing Enhanced Location Based Information for Wireless Handsets

摘要

Methods, devices and systems for generating enhanced location information on or about a mobile device may include hybrid lateration and trilateration solutions in which the mobile device performs location determination calculations with the aid 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.

主权项

1. A method of providing an enhanced location based service via a mobile device, including:
determining, by a processor of the mobile device, an initial position of the mobile device; generating local position information; generating external position information based on location information received from an external location tracking system; generating proximity position information based on distance information received from a second mobile device; generating final location information based on the determined initial position, the generated local position information, the generated external position information, and the generated proximity position information; and using the generated final location information to provide a location based service.
