Method and system for reactive power-saving
First Claim
1. A method for power management in a subscriber station, wherein at least two predefined power-saving modes are defined for the subscriber station, the method comprising:
- (a) during a communication session between a subscriber station and an access network, determining a packet inter-arrival time for data received from the access network;
(b) determining whether the packet inter-arrival time indicates that the communication session is in a high-activity state or, in the alternative, indicates that the communication session is in a low-activity state;
(c) if the packet inter-arrival time indicates that the communication session is in the low-activity state, then selecting a first power-saving mode for use by the subscriber station; and
(d) if the packet inter-arrival time indicates that the communication session is in the high-activity state, then selecting a second power-saving mode for use by the subscriber station.

Abstract
Disclosed herein is a method and system for power management in a subscriber station. The method involves (a) during a communication session between a subscriber station and an access network, determining a packet inter-arrival time for data received from the access network; (b) determining whether the packet inter-arrival time indicates that the communication session is in a high-activity state or, in the alternative, indicates that the communication session is in a low-activity state; (c) if the packet inter-arrival time indicates that the communication session is in the low-activity state, then selecting a first power-saving mode for use by the subscriber station; and (d) if the packet inter-arrival time indicates that the communication session is in the high.

14. An apparatus configured to engage in communications via an access network, wherein the apparatus is further configured to be able to selectively operate in at least a first power-saving mode and a second power-saving mode, the apparatus comprising:
-
a power source, wherein operating in the first or second power-saving mode reduces demand for power from the power source; a processor; and program code stored in data storage and executable by the processor to; (a) during a communication session via an access network, determine a packet inter-arrival time for data received from the access network; (b) determine whether the packet inter-arrival time indicates that the communication session is in a high-activity state or, in the alternative, indicates that the communication session is in a low-activity state; (c) if the packet inter-arrival time indicates that the communication session is in the low-activity state, then selectively operate in the first power-saving mode; and (d) if the packet inter-arrival time indicates that the communication session is in the high-activity state, then selectively operate in the second power-saving mode. - View Dependent Claims (15, 16, 17)

18. A method for power management in a subscriber station, the method comprising:
-
making a determination as to whether or not a communication session in which the subscriber station is engaged is a variable-activity communication session; and if the determination is that the communication session is a variable-activity communication session, then using a reactive power-saving method to conserve power during the communication session, wherein the reactive power-saving method comprises the subscriber station, during the communication session, selectively switching between two or more power-saving modes based on packet inter-arrival time of the communication session. - View Dependent Claims (19, 20, 21, 22, 23)
