<P>PROBLEM TO BE SOLVED: To discriminate exact behavior pattern of a mobile even when detection accuracy of location where the mobile exists is low. <P>SOLUTION: While obtaining a transition process of behavior state where likelihood to a hidden Markov model of the behavior pattern becomes the largest for every m pieces of behavior patterns accumulated in a mobile behavior pattern accumulation part 2, a mobile behavior state process estimation section 3 which obtains the likelihood of the transition process of the behavior state to m behavior patterns is set up, and m likelihoods obtained from m behavior patterns by the mobile behavior state process estimation section 3 are compared and the behavior pattern corresponding to the transition process of the behavior state having the largest likelihood is discriminated. <P>COPYRIGHT: (C)2008,JPO&INPIT |
