Abstract
Abstract A data communication method in which a transmitting station divides data into a plurality of data blocks and transmits the data blocks in parallel through a plurality of communication lines, and a receiving station receives the data blocks transmitted from the transmitting station through the plurality of communication lines and composes the data blocks into original data. In the data communication method, it is detected that a new transmission request is present during a parallel data transmission through a plurality of communication lines, one or more of the communication lines are released to continuously use the remaining communication lines for the parallel data transmission in response to the detected new transmission request, and a new data transmission is performed through the released communication line or lines.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
123 words
A data communication method in which a transmitting station divides data into a plurality of data blocks and transmits the data blocks in parallel through a plurality of communication lines, and a receiving station receives the data blocks transmitted from the transmitting station through the plurality of communication lines and composes the data blocks into original data, said data communication method comprising the steps of: detecting that a new transmission request is present during a parallel data transmission through a plurality of communication lines; releasing at least one of the communication lines to continuously use the remaining communication lines for the parallel data transmission in response to the detected new transmission request; and performing a new data transmission through the released communication line.
Claim 2
Dependent Claim
123 words
A data communication method in which a transmitting station divides data into a plurality of data blocks and transmits the data blocks in parallel through a plurality of communication lines, and a receiving station receives the data blocks transmitted from the transmitting station through the plurality of communication lines and composes the data blocks into original data, said data communication method comprising the steps of: detecting that a new transmission request is present during a parallel data transmission through a plurality of communication lines; releasing at least one of the communication lines to continuously use the remaining communication lines for the parallel data transmission in response to the detected new transmission request; and performing a new data transmission through the released communication line.
Claim 3
Dependent Claim
40 words
The data communication method according to claim 1, wherein when the new data transmission has been completed before the parallel data transmission is completed, the released communication line and the remaining ones are both used for the parallel data transmission.
Claim 4
Dependent Claim
28 words
The data communication method according to claim 1, wherein said new transmission request requests a data transmission using a plurality of communication lines in a super-high-speed communication mode.
Claim 5
Dependent Claim
23 words
The data communication method according to claim 1, wherein said new data transmission uses the released communication line and a free communication line.
