Abstract

PURPOSE:To collect data equally by setting a group to which a terminal station belongs by random changing. CONSTITUTION:Zone pattern comparator circuit 11 compares a polling signal from a base station with a local zone detected by automatic or manual setting and only when the both agree each other, a start signal is sent to transmission control timing circuit 12. The output signal of false random pattern generating circuit 13 is so set that the elapse time between the reception of the start signal and the transmission of the signal to transmission control circuit 14 will be random at every mobile station.
