PURPOSE:To contrive the improvement of the line utilizing efficiency and the transmission efficiency of a common signal line by separating a part of a radio line as an exclusive line for a line release requesting signal being one of the line control signal. CONSTITUTION:An area (600 bits) by 2 slots among one frame 100 slots is separated as a pre-assigned TDMA line exclusive for a line release requesting signal and the area is divided into small slots (60 slots) at every 10-bit. Thus, a line release requesting signal line is secured independently for each of 60 lines, and although the common signal line of the slot random access system uses 98 slots in one frame, the line is used only for sending the line assignment request signal of 70 information bits. Thus, the line utilizing efficiency is improved and the collision between a line assignment requesting signal and a line release request signaling is eliminated and the improvement in the transmission efficiency of the common signal line is attained. |
