Non-transparent data transmission method of digital telecommunication system (NON-TRANSPARENT DATA TRANSMISSION IN A DIGITAL TELECOMMUNICATIONS SYSTEM)

摘要

The present invention relates to a digital telecommunication system, and more particularly to a non-transparent data transmission method. Transparent data connection (V. 110 + L2R / RLP) is provided between the sending party (A) and the receiving party (B), and coding is employed on that channel. The transmit buffer buffers the data frame to be transmitted and stores the transmitted data frame until it receives an acknowledgment of successful reception. This is solved in accordance with the present invention by observing the quality of the non-transparent connection and changing the channel coding of the connection to a more effective one if the quality of the connection drops to a certain threshold. At the time, however, more channel capacity is allocated for connection in accordance with the selected channel coding, so that the original nominal user rate may remain unchanged or remain unaltered.
