Abstract

Provided are methods of operating a gateway and a server, performing an intelligent negotiation in an Internet of Things (IoT) network. According to an example embodiment, a method of operating the gateway of an IoT system includes receiving status information from at least one of a plurality of end devices included in a local network, determining whether to start a negotiation based on a status of the local network that is analyzed based on the status information, transmitting a negotiation request to an external device, receiving a suggestion corresponding to the negotiation request from the external device, and transmitting a reply indicating whether to accept the suggestion to the external device.

First claim

What is claimed is:

1. A method of operating a gateway of an Internet of Things system, the method comprising:
receiving at the gateway status information from at least one of a plurality of end devices included in a local network;
determining by the gateway whether to start a negotiation based on a status of the local network that is analyzed based on the status information;
transmitting a negotiation request from the gateway to an external device, the external device being a server;
receiving a suggestion corresponding to the negotiation request from the external device;
transmitting a reply indicating whether to accept the suggestion to the external device,
wherein the negotiation request comprises a negotiation object, and
wherein the negotiation object corresponds to at least one of a data processing function, a network controlling function, and a system configuration; and
generating by the gateway a counter suggestion that is provided as the reply, based on the status of the local network and a local policy.

2. The method of claim 1 , further comprising
determining whether to accept the suggestion based on the status of the local network and a local policy.

3. The method of claim 1 , wherein the generating of the counter suggestion comprises
changing the local policy based on the received suggestion; and
generating the counter suggestion based on the changed local policy.

4. The method of claim 1 , further comprising
receiving a result of the negotiation; and
adopting the result of the negotiation,
wherein the result of the negotiation comprises an operation rule of a control device or at least one of the end devices.

5. The method of claim 4 , wherein the gateway performs a processing function based on the operation rule.

6. The method of claim 4 , wherein the gateway controls at least one of the end devices based on the operation rule.

7. The method of claim 1 , wherein the determining whether to start the negotiation comprises comparing a status value indicating the status of the local network with a threshold condition.

8. A method of operating a server of an Internet of Things (IoT) system, the method comprising:
receiving a negotiation request at a server from an external device external to the server and at a local network, the negotiation request being part of a negotiation and the external device being either an IoT device or a gateway device that communicates between the server and the IoT device;
generating, by the server, a suggestion corresponding to the negotiation request based on a status of the local network determined at least in part based on a status of the IoT device, wherein the IoT device and a gateway are included in the local network;
transmitting the suggestion from the server to the external device; and
receiving a reply sent from the external device to the server indicating whether the external device accepts the suggestion.

9. The method of claim 8 , when the received reply comprises an acceptance of the suggestion, further comprising
changing a local rule corresponding to the IoT device or the gateway based on the suggestion; and
transmitting the changed local rule as a result of the negotiation.

10. The method of claim 8 , further comprising
receiving at the server the status of the local network from the external device; and
storing the status of the local network in an internal database internal to the server.

11. A method of communicating in an Internet of Things (IoT) system, the method comprising:
receiving, by a control device, status information from at least one of a plurality of end devices included in a local network of the IoT system;
determining, by the control device, to start a negotiation based on a status of the local network that is analyzed based on the status information;
as a result of determining to start a negotiation, transmitting a negotiation request from the control device to an external device, and receiving the negotiation request at the external device;
performing a negotiation between the control device and the external device, to determine a rule or rule-set to use by the control device for communication; and
selecting and using the rule or rule-set for operations of the control device.

12. The method of claim 11 , further comprising:
determining to start the negotiation by comparing a status value indicating the status of the local network with a threshold condition.

13. The method of claim 12 , wherein performing the negotiation includes:
generating a suggestion by a first device from among of the control device and the external device and sending the suggestion to a second device from among the control device and the external device, the second device being the other device that is not the first device;
receiving the suggestion by the second device; and
responding to the suggestion by: transmitting an acceptance message to the first device, sending a counter suggestion to the first device, or sending a request for another suggestion to the first device.

14. The method of claim 13 , further comprising:
changing a local rule corresponding to the local network based on the suggestion, the counter suggestion, or the another suggestion.
