A location-information discrimination method and device are provided that can accurately discriminate between locations of a mobile terminal in keeping with an actual environment. A discrimination value calculator calculates a discrimination value that is dependent on the amount of a change, from a predetermined value, in the received power of a radio signal received by a mobile terminal from a base station and on the duration of that change in the received power. The determination section compares the discrimination value with a predetermined value, thereby determining whether the mobile terminal is located indoors or outdoors. |
