<P>PROBLEM TO BE SOLVED: To provide a method for predicting whether or not a telephone call that is being set up will be considered annoying by a called party and, if so, for preventing it from being established. <P>SOLUTION: An illustrative embodiment predicts whether a telephone call will be considered annoying by a called party based on temporal characteristics of previous calls from the same caller. For example, when a called party receives an unwanted telephone solicitation, he or she will usually hang up within the first minute. If many telephone calls are made from the same caller and all of these calls last under a minute, then it is reasonable to predict that further calls from this caller will be considered annoying. <P>COPYRIGHT: (C)2011,JPO&INPIT |
