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 configuring a mobile device to receive first location information from a plurality of other devices, and use the received first location information to determine an approximate location of the mobile device to a first level of accuracy. The mobile device may then group itself with one or more wireless transceivers in proximity to the mobile device, and send the approximate location to the wireless transceivers in the communication group. In response, the mobile device may receive second location information from the one or more wireless transceivers in the communication group in response to sending the determined approximate location, and use the received second location information to determine a more precise location of the mobile device to a second level of accuracy.

主权项

1. A method of determining a location of a mobile device, comprising:
receiving, by a processor of the mobile device, first location information from a plurality of other devices; using the received first location information to determine an approximate location of the mobile device to a first level of accuracy; grouping the mobile device with one or more wireless transceivers in proximity to the mobile device to form a communication group; sending the determined approximate location to the one or more wireless transceivers in the communication group; receiving second location information from the one or more wireless transceivers in the communication group in response to sending the determined approximate location; and using the received second location information to determine a more precise location of the mobile device to a second level of accuracy, wherein the second level of accuracy is greater than the first level of accuracy.
