Power saving system for time-division multiple access radiocommunication network
First Claim
1. A power saving system for a time-division multiple access communication network having a first station and a plurality of second stations capable of individually establishing connections with said first station in response to a selection signal and relaying information signals through the established connections, the system comprising:
- means for interleaving a power saving control signal at periodic intervals with said selection signal and said information signals and transmitting the interleaved signals from said first station to said second stations;
a plularity of means associated respectively with said second stations for individually cutting off power supplies to said second stations for a predetermined period in response to said control signal; and
means for detecting the moment a connection is being established, identifying the second station establishing the connection, and selectively inhibiting one of said power cut-off means associated with the identified second station from responding to said control signal, while allowing the remainder of said power cut-off means to respond to said control signal.

Abstract
In a time-division multiple access (TDMA) communication network, a power saving system interleaves a power saving control signal at periodic intervals with a selection signal and information signals and transmits the interleaved signals from a master station to slave stations. A plurality of power cut-off circuits are associated respectively with the slave stations for individually cutting off power supplies to the slave stations for a predetermined period in response to the control signal. A detector is provided for detecting the moment a connection is being established, identifying the slave station establishing the connection and selectively inhibiting the power cut-off circuit associated with the identified station from responding to the control signal, while allowing the remainder of the power cut-off means to respond to the control signal.

4. A power saving system for a time-division multiple access communication system having a base station, a plularity of terminal stations capable of establishing connections with said base station in response to a selection signal and one or more repeater stations for relaying information signals through said connections, comprising:
-
means for interleaving a power saving control signal at periodic intervals with said information signals and transmitting the interleaved signals from said base station to said terminal stations through one or more of said repeater stations; a plularity of means associated respectively with said repeater and terminal stations for individually cutting off their power supplies for a predetermined period in response to said control signal; and means for detecting the moment a connection is being established, identifying the repeater station and terminal station between which said connection is being established and selectively inhibiting one of said power cut-off means associated with the identified repeater station and terminal station from responding to said control signal, while allowing the remainder of said power cut-off means to respond to said control signal. - View Dependent Claims (5, 7, 9)

8. A method for saving power in a time-division multiple access communication system, the system comprising a first station and a plurality of second stations capable of individually establishing connections with said first station in response to a selection signal and relaying information signals through the established connections, the method comprising:
-
(a) interleaving a power saving control signal at periodic intervals with said information signals; (b) transmitting the interleaved signals from said first station to said second stations; (c) detecting the moment a connection is being established and identifying the second station establishing said connection; (d) inhibiting the second station to which said connection is being established from responding to said control signal; and (e) individually cutting off power supplies to the second stations other than the last-mentioned second station for a predetermined period in response to said control signal.
