FIELD: radio engineering, communication.
SUBSTANCE: determining unit determines that an access point information element, stored in a first storage area, cannot be stored in a second storage area; a second control unit stores the access point information element, stored in the first storage area, in the second storage area while removing, from a plurality of access point information elements stored in the second storage area, the access point information element on the access point whose radio field strength is lower than for any access point indicated by the access point information element stored in the first storage area.
EFFECT: low probability of failure while storing access point search results, having radio field strength greater than a predetermined level.
