Distributed search method

摘要

A method is provided for searching for a lost asset (50) equipped with a short-range wireless transceiver (52). A finder service (40) sends out a search request (36) including a lost-asset identifier, this request being sent over a mobile radio infrastructure (10) to a plurality of mobile devices (20). These devices transmit on the request in their immediate vicinity using short-range wireless transceivers (21). Upon a mobile device (20B) receiving back a response from the lost asset (50), it returns a found message (35) over the mobile radio infrastructure (10) to the finder service (40), this message either including location data concerning the whereabouts of the lost asset or enabling such data to be obtained by the finder service. <IMAGE>
