Battery saving system for interrupting power supplies at intervals variable with traffic pattern
First Claim
1. A battery saving system for a communications system having a base station and a remote station, comprising:
- first means in said base station for storing traffic pattern data representative of a traffic volume of said communications system during every hour of a day;
a time-keeping circuit for generating a time-of-day signal;
second means in said base station for reading said traffic pattern data from said first means in response to said time-of-day signal and transmitting a battery-saving signal to the remote station at intervals which are variable as a function of said traffic volume of the read traffic pattern data; and
third means in said remote station for interrupting power of the remote station in response to said battery-saving signal, so that said remote station is powered for a shorter interval during a light traffic period and for a longer interval during a heavy traffic period.

Abstract
In a communications system, a base station has a memory for storing interval control values representative of time-varying traffic pattern of the communications system. A time-keeping circuit recalls a stored interval control value from the memory according to different time of day and a battery-saving command signal is sent from the base station at variable intervals as a function of the value recalled from the memory. Power supplies of a remote station are interrupted for a constant brief interval in response to the battery-saving signal, so that the remote station is powered for a shorter interval during a light traffic period and for a longer interval during a heavy traffic period. In a preferred embodiment, traffic data is automatically collected from the communications system and the stored interval control values are updated according to the collected traffic data.

8. A method of saving power supplies of a communications system, comprising:
-
a) storing traffic pattern data representative of a traffic volume of said communications system during every hour of a day in a memory; b) generating a time-of-day signal representing a time of day; c) recalling the stored traffic pattern data from said memory in response to said time-of-day signal and transmitting a battery-saving signal from a base station to a remote station at intervals variable as a function of the traffic volume of said recalled traffic pattern data; and d) interrupting power supplies of the remote station in response to said battery saving signal, so that said remote station is powered for a shorter interval during a light traffic period and for a longer interval during a heavy traffic period. - View Dependent Claims (9)
