METHOD AND SYSTEM FOR PROVIDING ENHANCED LOCATION INFORMATION FOR WIRELESS MOBILE DEVICES Russian patent published in 2015 - IPC H04W64/00 

FIELD: radio engineering, communication.

SUBSTANCE: invention provides methods, devices and systems for generating enhanced location information on or about a mobile device, which 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 obtained 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 use local sensors to further enhance its location information.

EFFECT: high accuracy of locating mobile devices.
