Data Communication Terminal, Radio Base Station Searching Method, and Program

A radio base station searching method used in a data communication terminal connected to an information device body and used as a modem for performing communication between the information device body and a surrounding radio base station, the radio base station searching method comprising:

• a search frequency information acquisition procedure of receiving search frequency setting information of a radio base station from the information device body side;
• a setting data storage procedure of storing the search frequency setting information received in the search frequency information acquisition procedure;
• a search frequency development procedure of determining a frequency to be searched for based on the search frequency setting information stored in the setting data storage procedure;
• and
• a radio base station search procedure of searching for a radio base station at the frequency determined in the search frequency development procedure.

A program for causing a computer of a data communication terminal connected to an information device body and used as a modem for performing communication between the information device body and a surrounding radio base station, to execute:

• a search frequency information acquisition procedure of receiving search frequency setting information of a radio base station from the information device body side;
• a setting data storage procedure of storing the search frequency setting information received in the search frequency information acquisition procedure;
• a search frequency development procedure of determining a frequency to be searched for based on the search frequency setting information stored in the setting data storage procedure;
• and
• a radio base station search procedure of searching for a radio base station at the frequency determined in the search frequency development procedure.
