Communication device and communication method
First Claim
1. A communication device, wherein data is transmitted and received via a communication section and a line, comprising:
- decision means for deciding whether or not to transmit and receive data based on predetermined information corresponding to the state of the line or the internal state of the device or whether or not to interrupt communications if the device is currently in a transmission/reception state; and
a controller for controlling said communication section according decision results from said decision means.

Abstract
The communication device includes a communication microcomputer 203 and an information-processing microcomputer 207. The communication microcomputer 203 has a line quality measuring section 301, a battery level measuring section 302, a data table 304, and a data transmission/reception decision section 303. The information-processing microcomputer 207 has a data transmission/reception prediction section 307 and a communication processing section 305. 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 section 303 implements 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 section 303 interrupts 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.

12. A communication method suitable for a communication device which transmits and receives data via a communication section and a line, said method comprising the steps of:
-
deciding whether or not to transmit and receive data based on predetermined information corresponding to the state of the line or the internal state of the system or whether or not to interrupt communications if the device is currently in a transmission/reception state; and
controlling said communication section to disconnect the line after the logging-out in a predetermined communication procedure, in accordance with decision results in said decision step. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20, 21, 22)
