摘要
The present invention relates to a data transmission method between a base station controller (BSC) and a base transceiver station (BTS) in a digital mobile communication system, for varying a length of a frame according to a data transmission rate, thus improving transmission efficiency of a trunk between the BSC and BTS. When transmitting voice and data from the BSC to the BTS, a selection unit in the BSC generates a length-varied frame according to a transmission rate of a packet to be transmitted to the BTS and transmits the variable length frame to the BTS. Alternatively, when transmitting voice and data from the BTS to the BSC, a base station common processor in the BTS generates a length-varied frame according to a transmission rate of a packet to be transmitted to the BSC and transmits the variable length frame to the BSC. Therefore, the present invention can effectively use a channel bandwidth between the BTS and the BSC, thereby improving trunk efficiency.
