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.
Claims20
A method, comprising;
- determining from a received acknowledgement message at an end device whether the end device is defined on a zigbee network by evaluating a defined flag portion of a status field;
- and
- if the device is not defined on the zigbee network as the defined flag portion of the status field is not set, transmitting a join request message from the end device to the zigbee network.
A device, comprising:
- at least one transmitter;
- at least one receiver;
- at least one processor;
- and
- at least one memory;
- wherein the processor processes an acknowledgement message to determine if the device is defined on a zigbee network by evaluating a defined flag portion of a status field and, if the device is not defined on the zigbee network as the defined flag portion of the status field is not set, the processor causes the transmitter to transmit a join request message to the zigbee network.
A non-transitory computer readable medium having computer executable instructions for execution by a processor, the computer executable instructions for:
- receiving an acknowledgement message at an end device, the acknowledgement message indicating whether the end device is defined on a zigbee network by evaluating a defined flag portion of a status field;
- receiving from the end device a join request message from the end device if the device is not defined on the zigbee network as the defined flag portion of the status field is not set;
- and
- joining the end device to the zigbee network.
