| 9. A mobile communication terminal for communicating a data with a first base station or a second base station, comprising:
a first communication unit configured to perform the data communication with the first base station at a first communication
rate;
a second communication unit configured to perform the data communication with the second base station at a second communication
rate higher than the first communication rate;
a input unit configured to accept an input of a setting instruction of an automatic stop mode or an input of a setting instruction
of a manual stop mode;
a first control unit coupled to the first communication unit and the second communication unit, and configured to switch from
the second base station to the first base station during a period in which the data communication with the second base station
is performed;
a second control unit coupled to the first communication unit, and configured to calculate a remaining communication time
necessary to complete the data communication from a switching time point on the basis of a remaining amount of data which
has not communicated yet, before switching the communication partner;
a third control unit coupled to the first control unit and the second control unit, configured to continue the data communication
with the first base station if the remaining communication time is shorter than a threshold, and configured to stopping the
data communication with the first base station if the remaining communication time is longer than the threshold and if automatic
stop mode is input by the input unit;
a display unit configured to display the calculated remaining communication time if the manual stop mode is input and if the
remaining communication time is longer than the threshold;
a fourth control unit configured to continue the data communication with the first base station if a communication continuation
instruction is input by the input unit and after the display unit displays the calculated remaining communication time, and
configured to stop the data communication with the first base station if the communication stop instruction is input by the
input unit and after the display unit displays the calculated remaining communication time.
