ABSTRACT:
The communication device includes a communication microcomputer203and an information-processing microcomputer207.The communication microcomputer203has a line quality measuring section301,a battery level measuring section302,a data table304,and a data transmission/reception decision section303.The information-processing microcomputer207has a data transmission/reception prediction section307and a communication processing section305.The electric field level, degradation in line quality, and the remaining amount of a battery are periodically monitored during data communication such as electronic mail reception. The data transmission/reception decision section303implements a decision process based on various predetermined information sets acquired through the monitoring. When deciding that the line is disconnected during communication, the data transmission/reception decision section303interrupts the mail reception and performs a logging-out with the server, thus disconnecting the line. As a result, it can be avoided that the connection between the terminal and the server is maintained.
