Title: Intermittent receiving system
Inventor: KOBAYASHI KATSUMI
IPC: H04W84/02
Filed: 1982-02-19
Abstract: PURPOSE:To save the electric power, by transmitting several times call signals to a queuing mobile station from a base station, and always turning on and off the power supply of a control channel receiver with a porper period at the mobile station to select said period and ON time. CONSTITUTION:A call signal of transmission signal time tau is transmitted from a base station via a control channel, and an answer to be given from the base station is waited within a time T. This action is repeated plural (N) times. For the mobile station, the ON and OFF times tON and tOFF of power supply are decided so as to satisfy tON >=2tau+T and tOFF <=(N-2)tau+(N-)T. The output of a power supply part 11 of the mobile station is turned on and off by an ON/OFF part 12 and fed to a receiving part 13, a synthesizer part 15 and a control part 16 respectively. The power is always, supplied to a data storing RAM17 only. As a result, at least a call signal can be completely received while the power supply is kept on, and just (N-1) units of call signals are included among N units of call signals at worst while the power supply is kept off.
