MOBILE TERMINAL, SYSTEM AND METHOD
First Claim
1. A mobile terminal having a continuous positioning function, comprising:
- a radio positioning unit configured to derive a position of the mobile terminal in continuous positioning;
a movement detection unit configured to detect a movement distance and a traveling direction of the mobile terminal;
a target zone setting unit configured to set a target zone based on a confirmed position of the mobile terminal determined as being valid in the continuous positioning and the movement distance and the traveling direction of the mobile terminal detected by the movement detection unit, the target zone comprising an area to which it is estimated that a user has moved; and
a validity determination unit configured to determine whether the position of the mobile terminal measured by the radio positioning unit is included in the set target zone to determine validity of the measured position of the mobile terminal.
