System and method for power conservation in a wireless device
First Claim
1. A method, comprising:
- switching, by a wireless computing unit, from a first communication mode to a second communication mode at a predefined time interval, wherein the unit receives wireless signals only when in the second communication mode, the first communication mode being a power-save mode;
receiving a wireless signal by the unit;
initiating a wireless connection to a wireless arrangement to obtain traffic data from the wireless arrangement when the signal includes a traffic data indicator, the indicator being indicative of existence of the traffic data; and
switching the unit into the first communication mode when the indicator is absent from the signal.

Abstract
Described is a system and method for power conservation in a wireless device. The method includes switching, by a wireless computing unit, from a first communication mode to a second communication mode at a predefined time interval. The unit receives wireless signals only when in the second communication mode, and the first communication mode is a power-save mode. The unit then receives a wireless signal, and initiates a wireless connection to a wireless arrangement to obtain traffic data from the wireless arrangement when the signal includes a traffic data indicator which is indicative of existence of the traffic data. The unit switches into the first communication mode when the indicator is absent from the signal.

11. A system, comprising:
-
a wireless computing unit having first and second communication modes, the first communication mode being a power-save mode, the unit receiving wireless signals only when in the second communication mode, the unit switching to the second mode at a predefined time interval; and
a network management arrangement transmitting a wireless signal with a traffic data indicator only when traffic data for the unit exists;
wherein when the unit receives the signal including the indicator, the unit initiates a wireless connection to the arrangement to obtain the traffic data, and wherein when the indicator is absent from the signal, the unit switches into the first mode. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19)
