Abstract: The present invention relates to a hybrid data transmission system and a transmission method thereof. The hybrid data transmission system according to an embodiment of the present invention comprises: a wireless access point; a reference terminal device for determining whether target data received via a preset channel from the wireless access point is in a normal state, and if in a normal state, transmitting a reception confirm signal to the wireless access point; and at least one neighboring terminal device, affiliated to a communication range of the wireless access point, for selectively receiving the target data according to the communication mode, wherein the wireless access point, if receiving the reception confirm signal from the reference terminal device, transmits new target data to the reference terminal device. Therefore, data transmission speed between terminal devices over the wireless network can be enhanced and the reliability in data transmission can be enhanced.

Abstract: Disclosed are a method for compressing a TCP header and a recording medium recording the same. the method for compressing a TCP header in accordance with an aspect of the present invention includes a step of storing an initial value of the TCP header according to a connection packet when connection with a correspondent node using a TCP/IP protocol is completed and a step of generating a TCP compression header including a compression method field on which a compression method of predetermined contents of the TCP header is individually recorded and a compression value field on which a compression value of the predetermined contents is recorded according to the compression method based on the initial value by analyzing the TCP header of a transmission packet transmitted to the correspondent node. According to the present invention the TCP/IP protocol can be efficiently applied to a low power WRAN transmitting and receiving a small amount of packets by compressing the TCP header.

Abstract: The present invention relates to a movable docking station, a mobile terminal for controlling docking thereof, and a movable docking system. A mobile terminal for controlling docking of a movable docking station according to an embodiment of the present invention comprises: an application management unit for managing the execution of a handwriting application; a docking sensing unit for sensing whether the mobile terminal is docked on the movable docking station; and a control unit for controlling to move, if the mobile terminal is docked, the movable docking station with a robot arm holding a handwriting means to write letter content provided by the handwriting application in a predetermined area. Thus, the mobile terminal can be docked on the movable docking station to allow the movable docking station to write the letter content provided by the handwriting application installed to the mobile terminal while moving, thereby writing desired letter content on large banners or hand-written posters without using a large format printer.
