Mobile terminal and method for executing scanning of radio signals

A mobile terminal connectable to a first radio communication system according to the Code Division a Multiple Access standard, and a second radio communication system which has a different radio communication scheme from the first radio communication system and which includes a second radio base station, the mobile terminal comprising:

• a notification receiver configured to receive a notification containing a spreading code from a first radio base station constituting the first radio communication system, the spreading code being assigned to the first radio base station and also assigned to another radio base station which is separated from the first radio base station by a predetermined distance or more;
• a storage configured to store neighboring base station information in which position information indicating the second radio base station and a certain position near the second radio base station is associated with the spreading code;
• a position measuring unit configured to measure a current position of the mobile terminal;
• a spreading code determining unit configured to determine whether or not the spreading code contained in the notification received by the notification receiver matches the spreading code contained in the neighboring base station information;
• a position determining unit configured to determine whether or not the certain position indicated by the position information contained in the neighboring base station information is within a predetermined distance from the current position measured by the position measuring unit;
• and
• a scanning unit configured to execute scanning for radio signals transmitted from the second radio base station, if the spreading code determining unit determines that the spreading code contained in the notification matches the spreading code contained in the neighboring base station information, and also if the position determining unit determines that the certain position indicated by the position information is within the predetermined distance from the current position.
