A trunk transmission efficiency improvement method between a control station and a base station of a digital mobile communication system

摘要

The present invention relates to a trunk transmission efficiency improvement method between a control station and a base station in a digital mobile communication system that improves transmission efficiency of trunks between a control station and a base station by varying a length of a frame according to a data transmission rate, When a voice or data packet is received, checks whether the packet is a packet transmitted at a certain transmission rate, and generates a voice / data field of a frame to transmit voice or data by varying the length of the voice / data field according to the examined information transmission rate . Accordingly, the entire length of the frame is varied, so that a variable length frame is transmitted between the control station and the base station with an efficient bandwidth according to the information transmission rate, thereby improving the transmission efficiency of the trunk between the control station and the base station.
