PURPOSE:To average and decrease the connection processing time by allowing a slave station having a call request to send a prescribed signal not sensed by a base station to a relay station during the operating period of all stations at first thereby keeping the relay operation and then to send a call signal during the inoperative period of all the stations. CONSTITUTION:When a call request exists in a slave station and the operating period T4 for all the stations is started, a control section 38 gives a command signal to a battery saving halt code sending section 39. When the output level of a BS length timer section 15 changes from '1' to '0' in the relay station and the period is transited to the inoperative period T5 of all the stations, since the output level at an output terminal Q of a memory 20 is at logical '1', a power control switch 8 keeps its closing operation. The slave station receives a control signal from the base station sent via the relay station keeping the relaying operation and a 'SYNC' detected by a SYNC code detection section 35 is inputted to the control section 38, then the control section 38 confirms the continuous relay operation by the relay station. A call code sending section 40 sends a call signal B to a transmitter 34 after the elapse of the time T3. |
