<P>PROBLEM TO BE SOLVED: To provide a method that can perform various operations based on distance-related functions associated with two or more devices. <P>SOLUTION: Association procedures may be performed based on a distance-related function associated for two or more devices. Presence management may be based on one or more determined distances. A distance-related function may take various forms including, for example, a distance between devices, two or more distances between devices, a rate of change in a relative distance between devices, relative acceleration between devices, or some combination of two or more of the these distance-related functions. <P>COPYRIGHT: (C)2012,JPO&INPIT |
