PURPOSE:To reduce the contention of request channels and to improve the channel transmission efficiency by allowing a sender side terminal equipment receiving a token from a designated data channel to send data by using the designated data channel. CONSTITUTION:A system is configured with radio communication using spread spectrum processing by five transmitters A-E. The transmitter A is made up of a transmission section 11, a reception section 12 a spread code control section 13, a transmission control section 14, a CPU 15 and a host CPU 16. The transmitters B-E take similar configuration to the transmitter A. When a token of a designated data channel is requested to a transmission destination terminal equipment from the sender side terminal equipment via a request channel, the transmission destination terminal equipment uses the designated data channel to send a transmission enable to the sender side terminal equipment in response to a request of the token at the destination terminal equipment. The sender side terminal equipment receiving the transmission enable from the designated data channel uses the designated data channel to send the data. |
