Maintaining network connectivity while operating in low power mode

摘要

A sub-system may maintain the network connectivity of the device, while the device is operating in low power. The sub-system may determine whether a pre-specified pattern is present in the incoming packet. The sub-system may send network messages such as keep-alive or time-out messages on behalf of the device if a first pattern is detected in the incoming packet. A first action associated with the first pattern may indicate that a network message is to be sent to another device. The sub-system may send a wake-up signal to the device if a second pattern is detected in the incoming packet. A second action associated with the second pattern may indicate that a wake-up signal is to be sent to the device.
