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.

10. A mobile communicating method for communicating data through a predetermined network line, comprising the steps of:
-
determining whether a 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 one having a higher communication speed of a plurality of radio transmitting/receiving devices which are different at least in data communication speed from one another when it is determined that the data signal is to be transmitted as a periodically transmitted data signal; setting an access point for each of said plurality of radio transmitting/receiving devices in accordance with a current position of a mobile unit; determining whether a communication by the one radio transmitting/receiving device is available though the set access point or not; controlling a data communication by the selected one radio transmitting/receiving device when it is determined that a communication by said one radio transmitting/receiving device is available through the set access point. - View Dependent Claims (11, 12)

13. A mobile communication device for communicating data 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; a first circuit which sets an access point for each of said plurality of radio transmitting/receiving devices in accordance with a current position of a mobile unit; a second circuit which determines whether a 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; a third circuit which selects one having a higher communication speed of said plurality of radio transmitting/receiving devices when said second circuit determines that the data signal is to be transmitted as a periodically transmitted data signal; a fourth circuit which determines whether a communication by the one radio transmitting/receiving device is available through the access point set by said first circuit or not; and a fifth circuit which controls a data communication by the one radio transmitting/receiving device selected by said third circuit when said fourth circuit determines that a communication by said one radio transmitting/receiving device is available through the set access point. - View Dependent Claims (14, 15, 16, 17, 18)
