Mobile communication terminal, method for registering location thereof and computer program product

A mobile communication terminal for performing radio communication, comprising:

• a radio wave receiving portion receiving radio waves from radio base stations;
• a radio base station selecting portion selecting at random one of the radio base stations that send the radio waves received by the radio wave receiving portion;
• and
• a location registration requesting portion sending a request for location registration of the mobile communication terminal to the radio base station selected by the radio base station selecting portion.

A mobile communication terminal for performing radio communication, comprising:

• a received radio wave intensity measuring portion measuring intensity of received radio waves that are radio waves received from radio base stations;
• a radio base station selecting portion selecting one of the radio base stations to which a request for location registration of the mobile communication terminal should be sent;
• and
• a location registration requesting portion sending a request for location registration of the mobile communication terminal to the radio base station selected by the radio base station selecting portion, wherein when the request is sent, the radio base station selecting portion initially selects a first radio base station whose received radio wave has the highest intensity measured by the received radio wave intensity measuring portion from among the radio base stations, and subsequently if the location registration in accordance with the request has failed, the radio base station selecting portion selects at random one of radio base stations whose received radio wave has the second highest or lower intensity measured by the received radio wave intensity measuring portion from among the radio base stations.

A method for registering a location of a mobile communication terminal for performing radio communication, comprising:

• making the mobile communication terminal receive radio waves from radio base stations;
• making the mobile communication terminal select at random one of the radio base stations from which the radio waves received by the mobile communication terminal have been sent;
• and
• making the mobile communication terminal send a request for location registration of the mobile communication terminal to the selected radio base station.
