Abstract

In order to minimize traffic on a Zigbee network, a gateway of the Zigbee network represents end devices in communications with peripheral networks. The gateway receives messages, such as status request messages, from the peripheral network intended for an end device on the Zigbee network. The Zigbee network generates a response message by retrieving stored data for the end device instead of communicating the received message to the end device.

First claim

What is claimed is:

1. A method, comprising:
receiving, by a gateway in a first network, a message from a peripheral network in a second network different from the first network, wherein the message is intended for an end device within the first network;
periodically receiving and storing data associated with the end device, the stored data comprising a last known status of the end device of the first network, one or more services provided by the end device, and a time at the end device;
determining the message intended for the end device is a status request of the end device's status and is answerable from the gateway and transmission of the message to the end device is not required, wherein the gateway is configured to respond to the status request from the peripheral network;
retrieving the stored data for the end device, the stored data being received from the end device and stored prior to receiving the message intended for the end device; and
generating, by the gateway, a response message in response to the received message based on the stored data, the response message intended for the peripheral network.

2. The method of claim 1 , wherein the response message is generated without communicating the received message to the end device.

3. The method of claim 1 , comprising transmitting the response message from the gateway to the peripheral network.

4. The method according to claim 1 , wherein the response message comprises a time indicative of a time at the end device.

5. A network, comprising:
one or more end devices in a first network; and
a gateway in the first network configured to:
receive a message from a peripheral network in a second network different from the first network intended for an end device in the first network;
periodically receive and store data associated with the end device, the stored data comprising a last known status of the end device of the first network, one or more services provided by the end device, and a time at the end device;
determine the message intended for the end device is a status request of the end device's status and is answerable from the gateway and transmission of the message to the end device is not required, wherein the gateway is configured to respond to the status request from the peripheral network;
retrieve the stored data for the end device, the stored data being received from the end device and stored prior to the message intended for the end device being received;
generate a response message in response to the received message based on the stored data intended for the peripheral network.

6. The network according to claim 5 , wherein the response is generated without communicating the received message to the end device.

7. A non-transitory computer-readable storage medium comprising computer-executable instructions for execution by at least one processor that, when executed, cause the at least one processor to:
receive a message at a gateway in a first network from a peripheral network in a second network different from the first network, wherein the received message is intended for an end device in the second network;
periodically receive and store data associated with the end device, the stored data comprising a last known status of the end device of the first network, one or more services provided by the end device, and a time at the end device;
determine the message intended for the end device is a status request of the end device's status and is answerable from the gateway and transmission of the message to the end device is not required, wherein the gateway is configured to respond to the status request from the peripheral network;
retrieve the stored data for the end device, the stored data being received from the end device and stored prior to receiving the message intended for the end device;
generate, by the gateway, a response message in response to the received message based on the stored data, the response message intended for the peripheral network.

8. The non-transitory computer readable storage medium according to claim 7 , wherein the response is generated without communicating the received message to the end device.

9. The non-transitory computer readable storage medium according to claim 7 , wherein the computer-executable instructions cause the at least one processor to determine a time indicative of a time at the end device and incorporate said time in said response message.
