Title: Selective calling system
Inventor: MURAI MAKOTO
IPC: H04W84/02
Filed: 1987-05-15
Abstract: PURPOSE:To reduce the current consumption of a selective call receiver without making receiving operation unstable by stopping the reception of a subsequent call word when an empty pattern is detected in the receiving operation. CONSTITUTION:When a collating circuit 30 detects the empty pattern during the receiving period of the group that its equipment belongs to, a power supply control means 32 outputs an opening signal to a switch 8, which is opened to cut off the supply of the output voltage of a battery 7 to a radio circuit 2. Thus when the number of selective call receivers to be called is smaller than the number of call words of one group, respective selective call signals are inserted into remaining call words where not selective call signal is inserted and they are sent out of a base station; and the selective call receivers monitor and empty pattern and when the empty pattern is detected, the radio circuit is powered off. Consequently, the current consumption of the selective call receivers is reduced more without making the receiving operation unstable.
