## Abstract

A method for issuing an access token of a device by a control point is provided. The method includes transmitting a search request message to the device, receiving, from the device, a search response message including first information indicating a type of the device, requesting access token issuance to the device using first information and second information, the second information including additional information about the device, and receiving the access token from the device. The second information may include model information about the device.

## Claims

### Claim 1

A method for issuing an access token of a device by a control device, the method comprising:
transmitting a request message to the device;
receiving, from the device, a response message including first information indicating a type of the device;
identifying a user interaction guide corresponding to the first information, and second information including model information about the device;
displaying the identified user interaction guide for the issuance of the access token;
in response to a user input through the displayed user interaction guide, requesting an issuance of the access token being needed for access of the device, to the device; and
receiving the access token from the device.

### Claim 2 (depends on 1)

The method of claim 1, wherein the response message further includes the second information.

### Claim 3 (depends on 2)

The method of claim 2, wherein the response message is at least one of an M-search response message and a notify message, and
wherein the second information is added to a “SERVER” field of the M-search response message or the notify message.

### Claim 4 (depends on 1)

The method of claim 1, further comprising:
transmitting a message requesting the second information, to the device using the first information; and
receiving a response message including the second information.

### Claim 5 (depends on 1)

The method of claim 1, wherein the displaying step comprises:
determining whether there is the user interaction guide for a model of the device corresponding to the model information in a database of the control device; and
if the user interaction guide is present, displaying the user interaction guide.

### Claim 6

A method for issuing an access token by a device, the method comprising:
receiving, from a control device, a request message requesting a search for the device;
transmitting, to the control device, a response message including first information indicating a type of the device;
receiving, from the control device, a request for issuing the access token of the device using the first information and second information; and
issuing the access token of the device, if the request for issuing the access token of the device is received in response to a user input through a user interaction guide displayed by the control device, which is identified corresponding to the first information and second information including model information about the device.

### Claim 7 (depends on 6)

The method of claim 6, wherein the response message further includes the second information.

### Claim 8 (depends on 7)

The method of claim 7, wherein the response message is at least one of an M-search response message and a notify message, and
wherein the second information is added to a “SERVER” field of the M-search response message or the notify message.

### Claim 9 (depends on 6)

The method of claim 6, further comprising:
receiving a message requesting the second information; and
transmitting a response message including the second information.

### Claim 10

An apparatus for getting an access token of a device issued, the apparatus comprising:
a transceiver configured to transmit and receive messages; and
a controller configured to control transmission of a request message to the device, to control reception of a response message including first information indicating a type of the device from the device, to control
identifying a user interaction guide corresponding to the first information and second information including model information about the device, display the identified user interaction guide for the issuance of the access token, and in response to a user input through the displayed user interaction guide, requesting of an issuance of the access token being needed for access of the device to the device.

### Claim 11 (depends on 10)

The apparatus of claim 10, wherein the response message further includes the second information.

### Claim 12 (depends on 11)

The apparatus of claim 11, wherein the response message is at least one of an M-search response message and a notify message, and
wherein the second information is added to a “SERVER” field of the M-search response message or the notify message.

### Claim 13 (depends on 10)

The apparatus of claim 10, wherein the controller is configured to control transmission of a message requesting the second information, to the device using the first information, and to receive a response message including the second information.

### Claim 14 (depends on 10)

The apparatus of claim 10, wherein the controller is configured to determine whether there is the user interaction guide for a model of the device corresponding to the model information in a database of the apparatus, and if the user interaction guide is present, to display the user interaction guide.

### Claim 15

A device for issuing an access token, the device comprising:
a transceiver configured to transmit and receive messages; and
a controller configured to control reception of a request message requesting a search for the device, from a control device, to control transmission of a response message including first information indicating a type of the device to the control device, to control reception of a request for issuing the access token of the device using the first information and second information, from the control device, and to control issuance of the access token of the device, if the request for issuing the access token of the device is received in response to a user input through a user interaction guide displayed by the control device, which is identified corresponding to the first information and second information including model information about the device.

### Claim 16 (depends on 15)

The device of claim 15, wherein the response message further includes the second information.

### Claim 17 (depends on 16)

The device of claim 16, wherein the response message is at least one of an M-search response message and a notify message, and
wherein the second information is added to a “SERVER” field of the M-search response message or the notify message.

### Claim 18 (depends on 15)

The device of claim 15, wherein the transceiver is configured to receive a message requesting the second information, and to transmit a response message including the second information.
