Abstract:
1. A method for publishing a position of a non-geotagged transceiver in a wireless communication system, wherein the non-geotagged transceiver is not associated with any direct position information, the method comprising: receiving one or more scan lists from one or more mobile devices; identifying the non-geotagged transceiver from the one or more scan lists; generating a periodic neighbor list associated with the non-geotagged transceiver; determining a first position of the non-geotagged transceiver based on the periodic neighbor list; determining a second position of the non-geotagged transceiver based on an accumulated neighbor list, wherein the accumulated neighbor list is a union between one or more qualified periodic neighbor lists that are generated over a consecutive period of time; determining if the first position and the second position agree; publishing a third position if the first position and the second position agree, wherein the third position is determined based on a union of the periodic neighbor list and the accumulated neighbor list; and resetting the accumulated neighbor list if the first position and the second position do not agree; wherein determining each of the first position, the second position, or the third position is based on one or more position estimation techniques, and publishing the third position includes making the third position available for a subsequent location based services application.
