BATTERY SAVING SYSTEM FOR INTERRUPTING POWER SUPPLIES AT INTERVALS VARIABLE WITH TRAFFIC PATTERN |
摘要 |
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.
