Abstract
For transmitting transmission data generated by a transmission data generator of a communication terminal device, a packet unit determining unit determines a packet unit for a lowest data communication rate for the transmission of the transmission data, among packet units (packet sizes) that can be recognized by a destination communication terminal device and that can be transmitted from the communication terminal device. A packet generator packetizes the transmission data according to the packet unit determined by the packet unit determining unit, and transmits the packetized transmission data to the destination communication terminal device.

7. A method for determining packet units for transmission data to be packetized and transmitted from a communication terminal device to a destination communication device, the method comprising the step of:
-
(1) determining packet units recognizable by said destination communication device for transmitting transmission data from said communication terminal device to said destination communication device;
(2) selecting a packet unit recognizable by said destination communication device to minimize the amount of transmission data for said packet unit; and
(3) packetizing said transmission data according to the packet unit selected in step (3). - View Dependent Claims (8, 9, 10)
