Abstract
An end device on a Zigbee network exits a power saving mode and transmits a wake notification message to the network. The network retrieves a cached status flag indicating whether the end device is defined on the Zigbee network and transmits the status flag to the end device. If the end device is undefined on the Zigbee network, the end device attempts to re-join the network. During the power saving mode, the network can cache messages intended for the end device and transmit the messages to the end device when the device exits the power saving mode.
