Method and system for selecting a sleep interval to improve battery life
First Claim
Patent Images
1. A method for selecting a sleep interval in a mobile communications device, comprising:
- negotiating a first sleep interval period with an access point;
negotiating a second sleep interval period with one or more entities other than the access point, wherein the second sleep interval period is longer than the first sleep interval period, and wherein the second sleep interval is negotiated after registration with the access point is complete, and wherein at least one of the one or more entities other than the access point is configured to buffer data; and
sending a signal to at least one of the one or more entities other than the access point indicating that buffering of data should cease.

Abstract
The disclosure is directed to a mobile communication device that is capable of accessing different types of networks such as a circuit-switched network and a packet-switched network. While communicating over the packet-switched network, the device negotiates a sleep interval that is longer than the ordinary interval available using the packet-switched network. In this manner, the device wakes less frequently and thereby conserves power. A buffering system is included so that data directed towards the device while it is asleep may be buffered for later delivery when the device awakens.
