Abstract

Disclosed is a method for mobile assisted sleep mode to reduce current drain in packet based mobile systems. The method comprising the step of receiving (102) from a network a channel condition threshold. Then, monitoring (104) a channel condition while in sleep mode. Then exiting (110) sleep mode in response to the determination (108) that the monitored channel condition is greater than the channel condition threshold.

Claims

1. A method for reducing current drain in a mobile device comprising:

providing a mobile device including an aperiodic mobile assisted sleep mode;

receiving from a network a channel condition threshold;

receiving an indication of pending data indication;

entering the aperiodic mobile assisted sleep mode and monitoring a channel condition;

determining that the channel condition is below the channel condition threshold;

waiting to exit the aperiodic mobile assisted sleep mode and send an awake indicator to the network until the channel condition is greater than the channel condition threshold.

2. The method of claim 1, further comprising receiving a first channel condition threshold and a second channel condition threshold from a network.

3. The method of claim 1, further comprising sending a first message including an awake indication and a first channel condition report indicating a first channel condition.

4. The method of claim 2, further comprising changing from a first sleep cycle to a second sleep cycle in response to determining that the determined channel condition has changed from the first channel condition to the second channel condition.

5. The method of claim 1, further comprising receiving a first DRX cycle indicator and a second DRX cycle indicator from the network.
