Abstract: The trunk routing device and method in a CDMA mobile communication system according to the present invention is contrived to assign and establish a plurality of trunks in the unit of packet to send packet data between a base station controller and a base transceiver station in order to uniformly utilize all trunk paths. Once receiving a new packet from a node connected to the base station controller, the invention extracts information about the packet designation from every packet and switches the packet data with the trunks connected to the designation in the unit of packet, thus sending the packet date to the base transceiver station.

Abstract: A transmission/reception concurrent matching apparatus for a multiple of TDM channels and a method thereof, wherein in matching the TDM channels, upon data transmission, a signal Serial Communication Controller(SCC) stores data to transmit per each data channel into a multiple of First-in First-out buffers(FIFOs) and transmits in order the data from each FIFO by one byte through a TDM bus, and upon data reception, stores the received data through the TDM bus into each FIFO and processes the data from each FIFO by reading out the data in order. As the number of SCC is reduced, the cost to process the data is saved.
