Connection method for smart home device and apparatus thereof

1. A method for connecting a user equipment (UE) to smart home devices, the method comprising:

identifying, when a connection request for a smart home device is detected, reception of a first broadcast message transmitted by the smart home device according to a first communication mode;

determining whether the smart home device permits communication mode negotiation based on information included in the first broadcast message; and

establishing a connection to the smart home device according to the first communication mode or a second communication mode based on a result of the determining,

wherein establishing the connection to the smart home device comprises:

transmitting, in case that the smart home device permits the communication mode negotiation, to the smart home device, a request message including information on a communication mode preferred by the UE;

receiving, from the smart home device, a response message including information on a communication mode preferred by the smart home device, as a response to the request message; and

establishing the connection to the smart home device according to the first communication mode or the second communication mode according to the communication mode preferred by the smart home device,

wherein the request message includes a first easy pairing mode information element (IE) field including a first “preferred supported” parameter indicating the communication mode preferred by the UE and a first “negotiation supported” parameter indicating a possibility of the communication mode negotiation of the UE, and

wherein the response message includes a second easy pairing mode IE field including a second “preferred supported” parameter indicating the communication mode preferred by the smart home device and a “social channel” parameter indicating a channel to be used for connection.

2. The method of claim 1 , wherein the first broadcast message includes a third easy pairing mode IE field, which includes a second “negotiation supported” parameter indicating a possibility of the communication mode negotiation and a “supported mode” parameter indicating a communication mode used by the smart home device.

3. The method of claim 1 , wherein establishing the connection to the smart home device further comprises establishing the connection to the smart home device according to the second communication mode in case that the smart home device does not permit the communication mode negotiation.

4. A user equipment (UE) capable of connecting to smart home devices, the UE comprising:

a transceiver configured to communicate with one or more smart home devices; and

a controller configured to:

identify, when a connection request for a smart home device is detected, reception of a first broadcast message transmitted by the smart home device according to a first communication mode,

determine whether the smart home device permits communication mode negotiation based on information included in the first broadcast message, and

establish a connection to the smart home device according to the first communication mode or a second communication mode based on a result of the determining,

wherein the controller is further configured to establish the connection by:

transmitting, in case that the smart home device permits the communication mode negotiation, to the smart home device, a request message including information on a communication mode preferred by the UE,

receiving, from the smart home device, a response message including information on a communication mode preferred by the smart home device, as a response to the request message, and

establishing the connection to the smart home device according to the first communication mode or the second communication mode according to the communication mode preferred by the smart home device,

wherein the request message includes a first easy pairing mode information element (IE) field including a first “preferred supported” parameter indicating the communication mode preferred by the UE and a first “negotiation supported” parameter indicating a possibility of the communication mode negotiation of the UE, and

wherein the response message includes second easy pairing mode IE field including a second “preferred supported” parameter indicating the communication mode preferred by the smart home device and a “social channel” parameter indicating a channel to be used for connection.

5. The UE of claim 4 , wherein the first broadcast message includes a third easy pairing mode IE field including a second “negotiation supported” parameter indicating a possibility of the communication mode negotiation and a “supported mode” parameter indicating a communication mode used by the smart home device.

6. The UE of claim 4 , wherein the controller is further configured to establish the connection to the smart home device according to the second communication mode in case that the smart home device does not permit the communication mode negotiation.

7. An electronic device capable of connecting to a user equipment (UE), the electronic device comprising:

a transceiver configured to communicate with the UE; and

a controller configured to:

transmit, for a connection to the UE, a first broadcast message according to a first communication mode, the first broadcast message including information for the UE to determine whether the electronic device permits communication mode negotiation, and

establish a connection to the UE according to the first communication mode or a second communication mode based on a result of the determining of the UE,

wherein the controller is further configured to establish the connection by:

receiving, in case that the electronic device permits the communication mode negotiation, from the UE, a request message including information on a communication mode preferred by the UE,

transmitting, to the UE, a response message including information on a communication mode preferred by the electronic device, as a response to the request message, and

establishing the connection to the UE according to the first communication mode or the second communication mode according to the communication mode preferred by the UE,

wherein the request message includes a first easy pairing mode information element (IE) field including a first “preferred supported” parameter indicating the communication mode preferred by the UE and a first “negotiation supported” parameter indicating a possibility of the communication mode negotiation of the UE, and

wherein the response message includes second easy pairing mode IE field including a second “preferred supported” parameter indicating the communication mode preferred by the electronic device and a “social channel” parameter indicating a channel to be used for connection.

8. The electronic device of claim 7 , wherein the first broadcast message includes a third easy pairing mode IE field including a second “negotiation supported” parameter indicating a possibility of the communication mode negotiation and a “supported mode” parameter indicating a communication mode used by the electronic devic.

9. The electronic device of claim 7 , wherein the controller is further configured to establish the connection to the UE according to the second communication mode in case that the electronic device does not permit the communication mode negotiation.
