Abstract
In a mobile communication system, the PAD of the data-processing-terminal-interface has a packet assembling/disassembling function for the protocol for data-link layer A and the protocol for data-link layer B. The protocol for data-link layer A of the data processing terminal prescribes that a frame, in which data transferred from the upper layer is inserted between flag sequences with a prescribed bit pattern, be transmitted usually, and that flag sequences without data transmission be transmitted when there is no data requiring transmission during communication. If flag sequences are transferred from the data processing terminal, the PAD deletes a part or all of the flag sequences and does not transfer them to the wireless communication unit. Consequently, a part or all of the flag sequences are not transmitted to the wireless communication channel. Therefore, power consumption by a wireless mobile station device or the like may be reduced, and the wireless channel may effectively used.
