Mobile communication device, mobile data communication method, and recording medium

摘要

PAD 1a of data-processing-terminal-interface 13 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 A45 of data processing terminal 11 prescribes that a frame, in which data transferred from the upper layer is inserted between flag sequences 31 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 33 are transferred from data processing terminal 11, PAD 1a deletes a part or all of flag sequences 33 and does not transfer them to wireless communication unit 12. 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.
