PURPOSE:To build up a system with high frequency utilization efficiency by multiplexing plural signals in time series and sending the result. CONSTITUTION:Communication signals 22-1-22-n sent from a gate exchange are inputted to a radio base station 30, inputted to a signal speed conversion circuit group 51 via a signal processing section 31, subject to speed conversion processing and the result is fed to a signal assignment circuit group 52 assigning a signal by each time slot. The signal assignment circuit group 52 stores an inputted high speed signal by each delimiter, reads a signal in timing information from a timing generating circuit 42 and sends it to a radio transmission circuit 32. Even when all radio channels are in use, calling is attained to a mobile radio equipment requesting a new call when an idle slot exists in time slots subject to time division to each radio channel respectively, and the effective utilization of frequencies is attained. |
