METHOD AND APPARATUS FOR POWER SAVING IN WIRELESS SYSTEMS
First Claim
1. A method for effecting power saving in a subscriber'"'"'s device associated with a wireless network which comprises a base station and at least said subscriber device, and wherein said subscriber'"'"'s device is operative to simultaneously receive at least two different traffic carrying connections each of which is characterized by one or more characteristics related to traffic demands associated with that connection, which method comprises:
- classifying each of said at least two different connections into corresponding power saving classes, provided that there are at least two different simultaneously active power saving classes associated with said at least two different connections;
for each of said power saving classes, determining required listening windows and required sleep windows;
determining unavailability periods of time for said subscriber'"'"'s device during which no communications will be exchanged between said base station and said subscriber'"'"'s device, such that the unavailability windows are determined based on a combination of the sleep windows of said at least two simultaneously active power saving classes;
initiating a power saving procedure in accordance with parameters associated with time domain location of the listening/sleep windows.

Abstract
A method is provided for carrying out a power saving procedure in a wireless subscriber terminal which is operative to receive at least two different services, each of which is characterized by one or more characteristics related to traffic demands associated with that service. The method comprises the following steps: classifying each of the at least two different services based on their traffic demand related characteristics into corresponding power saving classes, where there are at least two different power saving classes associated with the at least two different services; for each of the power saving classes, determining required listening windows and required sleep windows; exchanging messages between the base station and the subscriber'"'"'s device for synchronizing parameters for carrying out the power saving procedure.

9. A base station adapted to operate in a wireless network and comprising:
-
an interface operative to allow communication between said base station and a communication network associated therewith; at least one radio transceiver capable of transmitting communication traffic towards at least one subscriber device and receive communication traffic therefrom, wherein said base station is adapted to simultaneously communicate with said along at least two different traffic carrying connections, each of which is characterized by one or more characteristics related to traffic demands associated with that connection; means operative to classify each of said at least two different connections based on their traffic-demand-related characteristics into their corresponding power saving classes, provided that there are at least two different simultaneously active power saving classes associated with said at least two different connections; at least one processor adapted to; for each of said power saving classes, determine required listening windows and possible sleep windows; and determine unavailability periods of time for said subscriber'"'"'s device during which no communications will be exchanged between said base station and said subscriber'"'"'s device, such that the unavailability windows are determined based on a combination of the sleep windows of said at least two simultaneously active power saving classes; and means operative to transmit a message towards said subscriber'"'"'s device to enable activating a power saving procedure thereat in accordance with parameters associated with time domain location of the listening/sleep windows. - View Dependent Claims (10, 11, 12)

13. A subscriber'"'"'s terminal adapted to simultaneously receive at least two different traffic carrying connections each of which is characterized by one or more characteristics related to traffic demands associated with a respective connection, and wherein each of said at least two different traffic carrying connections is classified into a corresponding power saving class, provided that there are at least two different simultaneously active power saving classes associated with said at least two different connections, and wherein said subscriber'"'"'s terminal comprising:
-
an interface operative to allow communication between said subscriber'"'"'s terminal and a base station; at least one radio transceiver operative to transmit communication traffic towards said base station and receive communication traffic therefrom; at least one processor adapted to prevent exchange of communications between said base station and said subscriber'"'"'s device during unavailability periods of time associated with said subscriber'"'"'s device, said unavailability windows are determined based on a combination of sleep windows of said at least two simultaneously active power saving classes; and a power controller operative to reduce the power of said at least one radio transceiver for the duration of unavailability windows of time in which no communication will be exchanged between said base station and said subscriber'"'"'s terminal. - View Dependent Claims (14, 15)
