Abstract:
1. A mobile communication device for communicating a data signal through a predetermined network line, comprising: a plurality of radio transmitting/receiving devices which are different at least in data communication speed from one another; setting means for setting an access point for each of said plurality of radio transmitting/receiving devices in accordance with a current position of a mobile unit; first determining means for determining whether the data signal is to be transmitted or not as a periodically transmitted data signal due to a lapse of a predetermined period of time from a preceding update time; selecting means for selecting one having a higher communication speed of said plurality of radio transmitting/receiving devices when said first determining means determines that the data signal is to be transmitted as a periodically transmitted data signal; second determining means for determining whether a communication by the one radio transmitting/receiving device is available through the access point set by said setting means or not; and control means for controlling a data communication by the one radio transmitting/receiving device selected by said selecting means when said second determining means determines that a communication by said one radio transmitting/receiving device is available through the access point set by said setting means.
