Abstract :
TD-SCDMA truncking system is a developing direction in digital truncking system. Based on TD-SCDMA trunking system, a movable boundary dynamic channel allocation (MB DCA) scheme is proposed. The characteristic of the algorithm is that the data service can borrow the voice channel for data transmission when the voice channel is idle and the data register queue is not empty. When a new voice call comes in, data service is blocked and voice service re-occupies the channel. The simulation results show that the channel utilization have an effectively improvement.
