In this case, since the first electronic device 100 and the third electronic device 300 are located within a predetermined communication radius from each other, a short range communication link is formed between the first electronic device 100 and the third electronic device 300. .

More specifically, in a situation where the short-range communication module 116 of the first electronic device 100 radiates electromagnetic waves to the surroundings, the third electronic device 300 is within a predetermined distance from the first electronic device 100, that is, When approaching within a communication radius, the third electronic device 300 recognizes electromagnetic waves emitted from the first electronic device 100.

This is called NFC card emulation.

As described above, when the short-range communication module (120, 220) uses a band of the center frequency 13,56MHz, the communication radius may be preferably within 10cm. Therefore, when the distance between the first electronic device 100 and the third electronic device 300 is less than 10 cm, a short range communication link is formed between the first electronic device 100 and the third electronic device 300.

In the following description, a process of forming a short range communication link by bringing two devices into close proximity to each other will be referred to as tagging.

In the above, the short-range communication link according to an embodiment of the present invention has been described with reference to FIG. 3. Hereinafter, a management server according to an embodiment of the present invention will be described with reference to FIG. 4.

Hereinafter, the components will be described in order.

The communication unit 210 may include various modules for data communication with other electronic devices. The communication unit 210 may communicate with at least one of the first and third

electronic devices

100 and 300 illustrated in FIG. 1, for example.

The information related to the control right may include information about which electronic device has control right over which electronic device. In addition, the communication unit 210 may obtain a request message for requesting the right to control other electronic devices from a specific electronic device, and may transfer the obtained request message to the control unit 220.

The controller 220 may control each component of the management server 200. For example, the control unit 220 may generate the control right management database by collecting the control right related information obtained from the communication unit 210. For example, when the control unit 220 obtains a control right request message for the other electronic device, the control unit 220 controls the other electronic device through the control right management database. It is determined whether or not to have, and according to the determination result can be given again the control right so that the specific electronic device can control the other electronic device.

The control right management unit 230 may manage the control right management database generated by the control unit 220. For example, if there is an update of control right information, the control right management unit 230 may update it in the control right management database.

The configuration of the management server 200 has been described above with reference to FIG. 4. Hereinafter, a method of operating an electronic device according to an embodiment of the present invention will be described.

Subsequently, based on the control right information obtained through the first connection, a second connection for re-acquiring the control right for the third electronic device 300 may be formed.

For example, when the first electronic device 100 first acquires the control right for the third electronic device 300, the first electronic device 100 may simply acquire the control right through the short range communication link, and then the first electronic device 100 may acquire the control right. For example, when the third electronic device 300 is to be remotely controlled, the first electronic device 100 is to control the third electronic device 300 based on a control right previously obtained through a short range communication link. .

To this end, the method of operating an electronic device according to an embodiment of the present invention comprises the steps of: forming a first connection to obtain a control right for the third electronic device 300 (controlled device) based on the short-range communication link [ S100] and forming a second connection for re-acquiring the control right for the third electronic device 300 based on the obtained control right [S160]. Hereinafter, each step will be described in detail.

The first electronic device 100 may form a first connection for obtaining a control right for the third electronic device 300 based on the short range communication link [S100].

Step S100 is a step for the first electronic device 100 to first authenticate the control right with respect to the third electronic device 300, and the first electronic device 100 controls the control right for controlling the third electronic device 300. To obtain, a near field communication link may be used. That is, the first connection according to step S100 is to obtain the control right for the third electronic device 300 through the short range communication module in a state in which the first electronic device 100 does not have the control right for the third electronic device 300. It is for.

For reference, the characteristics of the near field communication link have various advantages.

For example, a near field communication link has the advantage that the link formation rate is faster than other communication links. More specifically, since the near field communication link performs automatic device authentication, a pairing process is unnecessary, such as Bluetooth or Wi-Fi. Thus, the near field communication link has a high link formation speed. In addition, the short-range communication link has the advantage that the target electronics is oriented. More specifically, since the short-range communication link is a link formed when two short-range communication modules are close to each other within a predetermined distance, the target electronic device that intends to form a link is designated by only approaching the distance to the target electronic device within a predetermined distance. do. Thus, the near field communication link is a target electronic device-oriented link scheme. In addition, the short-range communication link has the advantage of excellent security. More specifically, since the short-range communication link is a link method formed when two short-range communication modules are close to each other within a predetermined distance, signals are not transmitted to other electronic devices regardless of user intention.

Therefore, since the first electronic device 100 uses the short range communication link to initially authenticate the control right for the third electronic device 300, the first electronic device 100 has an effect of fast link formation speed, simple link formation, and excellent security. That is, a user of the first electronic device 100 may acquire the control right for the third electronic device 300 only by an operation of tagging (see FIG. 3) in order to control the third electronic device 300.

The method may further include controlling the third electronic device 300 [S118]. Hereinafter, each step will be described in detail.

The first electronic device 100 may enter a control mode [S110].

In this document, the control mode refers to a mode in which the first electronic device 100 controls another electronic device, and in the control mode, the first electronic device 100 does not have a control right for another electronic device. In this case, a protocol for obtaining a control right for another electronic device may be performed. Hereinafter, assuming that the first electronic device 100 does not have a control right for another electronic device, for example, the third electronic device 300, the first electronic device 100 is connected to the third electronic device 300. The following describes the process of entering the local area communication link.

The first electronic device 100 may form a short range communication link with the third electronic device 300 [S112].

When the first electronic device 100 enters the control mode, the first electronic device 100 may form a short range communication link with the third electronic device 300. The short range communication link is the same as described above with reference to FIG. 3. That is, the short range communication module 116 of the first electronic device 100 and the short range communication module of the third electronic device 300 approach each other within a predetermined distance, whereby the first electronic device 100 and the third electronic device 300 are located close to each other. A near field communication link is formed between

The first electronic device 100 may be authorized to control the third electronic device 300 [S114].

For example, the first electronic device 100 may be authorized to control the third electronic device 300 through a short range communication link formed between the first electronic device 100 and the third electronic device 300.

The first electronic device 100 may be authorized to control the third electronic device 300 in various ways.

For example, the first electronic device 100 outputs a security information input window for controlling the third electronic device 300 through the display 151. When the user inputs the security information, the first electronic device 100 receives the received security information. Is transmitted to the third electronic device 300, and if the security information is valid, the third electronic device 300 authenticates the control right to control the third electronic device 300 to the first electronic device 100. will be.

At least one of the first electronic device 100 and the third electronic device 300 may store information related to control right authentication.

For example, when the first electronic device 100 is authorized to control the third electronic device 300, the first electronic device 100 may store information about the third electronic device 300 in the memory 160. The first electronic device 100 may temporarily or semi-permanently store information related to the control right. The information on the third electronic device 300 may include at least one of information indicating that the controlled device to which the first electronic device 100 has the control right is the third electronic device 300, the control right acquisition time, and the control content information. It may include. In addition, the first electronic device 100 transmits information on the third electronic device 300 to the management server 200 as necessary, and the management server 200 based on the received information control data. You can build a base. This will be described later.

For example, when the third electronic device 300 authenticates the control right with respect to the first electronic device 100, the third electronic device 300 may temporarily and / or semi-permanently store information about the first electronic device 100 in a memory. have. The information on the first electronic device 100 may include at least one of information indicating that the third electronic device 300 grants control to the first electronic device 100, visual information, and control content information. In addition, information about the first electronic device 100 may also be transmitted to the management server 200 and used as the information about the third electronic device 300. This will be described later.

As a result, the first electronic device 100 may obtain a control right for the third electronic device 300 through the first connection, which is a short-range communication link. The first electronic device 100 may control the third electronic device 300 based on the obtained control right.

When the first electronic device 100 obtains the control right for the third electronic device 300 through the first connection according to the user's setting, the first electronic device 100 may terminate the procedure. In this case, step S160 shown in FIG. 5 may proceed. In contrast, when the first electronic device 100 obtains the control right for the third electronic device 300 through the first connection, the first electronic device 100 may execute the control application. It will be described in detail below.

The first electronic device 100 may execute a control application for controlling the third electronic device 300 [S116].

The first electronic device 100 executes a control application to generate a control signal for the third electronic device 300 based on the control right obtained in step S114.

The controller 180 of the first electronic device 100 may execute a control application that varies according to the type of the third electronic device 300. For example, when the third electronic device 300 is a DTV, the control application is a DTV control application, and when the third electronic device 300 is a computer, the control application is a computer control application and a third electronic device. When the device 300 is a washing machine, the control application is a washing machine control application, when the third electronic device 300 is an oven, the control application is an oven control application, the third electronic device 300 is a car In this case, the control application may be a vehicle control application. Thus, as the control application varies according to the type of the controlled device, the user may be provided with a UI optimized for the controlled device.

In addition, the controller 180 may execute a control application that varies according to the state of the third electronic device 300. For example, even when the third electronic device 300 serving as the controlled device is the same as the washing machine, when the state of the third electronic device 300 is being washed, the first electronic device 100 executes. When the state of the control application and the third electronic device 300 is a failure, the control application executed by the first electronic device 100 may be different so as to correspond to each state. Thus, as the control application varies according to the state of the controlled device, the user may be provided with a user interface optimized for the current state of the controlled device.

In addition, the first electronic device 100 may acquire a control application for controlling the third electronic device 300 in various ways. For example, the first electronic device 100 may select the third electronic device 300 based on identification information identifying at least one of a device name of the third electronic device 300 and a state of the third electronic device 300. A control application for controlling can be identified and the identified control application can be executed. If the first electronic device 100 determines that there is no control application for controlling the third electronic device 300, the first electronic device 100 may control the third electronic device 300 from a predetermined server or the third electronic device 300. The control application may be provided.

The first electronic device 100 may control the third electronic device 300 [S118].

The first electronic device 100 may obtain a command for controlling the third electronic device 300 from the user through the executed control application. The first electronic device 100 may control the third electronic device 300 by generating a control signal based on the command and transmitting the generated control signal to the third electronic device 300.

In this case, the control signal transmitted from the first electronic device 100 to the third electronic device 300 may include information indicating that the first electronic device 100 has control over the third electronic device 300. have. For example, the information indicating that the first electronic device 100 has control over the third electronic device 300 may be a unique control number assigned to the first electronic device 100 by the third electronic device 300. have.

As the third electronic device 300 obtains a control signal from the first electronic device 100, the third electronic device 300 may perform a control operation corresponding to the control signal. Therefore, the first electronic device 100 may control the third electronic device 300.

In the meantime, the first electronic device 100 may use a short range communication link in transmitting a control signal to the third electronic device 300, but may of course use another communication link. More specifically, the first electronic device 100 forms a handover protocol after forming a short range communication link with the third electronic device 300, thereby forming another communication link, and transmitting a control signal through the formed other communication link. Can transmit In this document, the handover protocol is a standard protocol defined by the NFC Forum and refers to forming an alternative communication link based on a short range communication link. The alternate communication link may include, for example, Bluetooth, Wi-Fi, or the like.

The first electronic device 100 may automatically perform a handover protocol after forming the short-range communication link with the third electronic device 300 in step S112, for example, to form a Wi-Fi link. In this case, the first electronic device 100 and the third electronic device 300 may perform step S114 or later through a Wi-Fi communication link. In addition, the first electronic device 100 may communicate with the third electronic device 300 through an alternative communication link handed over from step S114.

Accordingly, in order to maintain the short-range communication link between the first electronic device 100 and the third electronic device 300, it is possible to overcome the distance constraint that the distance between the two devices must be maintained within a predetermined distance.

According to step S100 described above with reference to FIG. 6, the first electronic device 100 may acquire a control right with respect to the third electronic device 300 through a short-range communication link. 3 may control the electronic device 300.

For reference, step S100 described with reference to FIG. 6 has described a method in which the first electronic device 100 is authorized to control the third electronic device 300, and step S100 described below with reference to FIG. 7. A method of managing the control right information obtained by the first electronic device 100 with respect to the third electronic device 300 will be described. In addition, since the sequence to be described below with reference to FIG. 7 is not incompatible with the sequence described with reference to FIG. 6, it will be understood that both of them can be performed incompatible.

Referring to FIG. 7, in operation S100, the management server 200 acquires control right information, and the management server 200 configures a control right database [S122]. ].

According to step S100 according to an embodiment of the present invention to be described with reference to FIG. 7, information on which electronic device has control over which electronic device is managed, whereby the specific electronic device is used for any electronic device. If control is desired, control authority authentication can be performed more simply by determining whether there was a control right before.

The management server 200 may acquire control right information [S120].

The control right related information provides information on which electronic device has control right over which electronic device. To this end, the control right related information may include at least one of control device identification information, controlled device identification information, control content information, control right acquisition time information.

The controller identification information indicates which electronic device has obtained the control right. Further, the controlled device identification information indicates which electronic device is controlled by the electronic device that has obtained the control right. Further, the control content information indicates information on how the controller has controlled the controlled device, and the control time information indicates when the controller has obtained the control right for the controlled device.

The management server 200 may obtain control right information in various ways. For example, the management server 200 may obtain control right related information from at least one of the first electronic device 100 and the third electronic device 300. More specifically, the management server 200 may obtain control right information by obtaining at least one of the information on the first electronic device and the information on the second electronic device.

In other words, as described with reference to FIG. 6, when the first electronic device 100 obtains the control right through the first connection, which is a short-range communication link, to the third electronic device 300, the management server 200 may control the first electronic device 100. The control right information may be obtained from at least one of the first electronic device 100 and the third electronic device 300.

The management server 200 may configure a control right management database [S122].

You can see what you asked for. In addition, it can be seen that the first electronic device 100 has acquired control rights for the TV and the refrigerator at 2011.07.27 15:00 PM and 2011.07.26 01:15 AM, respectively. In addition, the fourth electronic device (not shown) obtained the control right for the air conditioner on 2011.01.05 13:05 PM, and it can be seen that the temperature was set to 20 degrees from 15:00 PM to 18:00 PM in 2011.

Accordingly, the management server 200 can manage information on which electronic device has control over which electronic device based on the control right management database. That is, the management server 200 may determine that the first electronic device 100 has control over the washing machine, TV, and refrigerator, and the fourth electronic device 400 has control over the air conditioner.

As described above with reference to FIGS. 7 and 8, when the first electronic device 100 obtains the control right for the electronic device 300 through the short-range communication link, the management server 200 controls the control right. By managing the related information, it is possible to easily determine which electronic device, for example, the electronic device that can be controlled by the first electronic device 100, which requires a later control.

Referring back to FIG. 5, the first electronic device 100 may form a second connection for re-acquiring the control right for the third electronic device 300 based on the obtained control right [S160]. .

In step S160, when the first electronic device 100 attempts to control the third electronic device 300 again after obtaining the control right for the third electronic device 300 in step S100, the control right granted in step S100. To control the third electronic device 300 based on the.

For example, when the first electronic device 100 intends to remotely control the third electronic device 300, the first electronic device 100 may form a second connection in order to regain control of the third electronic device 300.

Also, since the second connection is for reuse of the control right acquired through the first connection, the second connection may be formed after the short-range communication link that is the first connection is terminated.

Hereinafter, step S160 will be described in more detail with reference to FIG. 9.

9 is a flowchart for explaining step S160 according to an embodiment of the present invention.

The control mode refers to a mode in which the first electronic device 100 can control another electronic device, as described above with reference to FIG. 6.

To this end, the first electronic device 100 may output a list of the electronic devices recognized by the first electronic device 100 through the display 151. For example, the first electronic device 100 may output, via the display 151, a list of at least one other electronic device that has obtained control right through a short range communication link.

Accordingly, the user can select a specific controlled device to be controlled from the output list. Hereinafter, for convenience of description, it is assumed that the third electronic device 300 is selected as a controlled device, and the description will be continued.

The first electronic device 100 may request the management server 200 to control the third electronic device 300, which is a controlled device [S174].

In this case, the first electronic device 100 may transmit a control permission re-authorization request message for the third electronic device 300 to the management server 200 through various communication links. For example, the first electronic device 100 may request permission to grant control to the management server 200 through various communication links such as Wi-Fi, data communication, Mocha, Zigbee, Bluetooth, and near field communication. In particular, when the first electronic device 100 is located far from the management server 200 and the third electronic device 300, a communication link other than the short range communication link may be used to remotely control the third electronic device 300. It may be desirable to request the management server 200 to grant the control right.

The control right permission request message may include identification information of the first electronic device 100 to have the status of the control device. By providing identification information of the first electronic device 100 to the management server 200, the management server 200 determines whether the first electronic device 100 has control over the third electronic device 300. You can check it. In addition, the control right permission request message may include identification information of the third electronic device 300 selected as the controlled device. By providing identification information of the third electronic device 300 to the management server 200, the management server 200 determines whether the first electronic device 100 has control over the third electronic device 300. You can check it.

Can be determined.

More specifically, the management server 200 determines which electronic device the first electronic device 100 has control over based on the identification information of the first electronic device 100 obtained from the first electronic device 100. In particular, when the identification information of the third electronic device 300 corresponding to the controlled device is received from the first electronic device 100, the first electronic device 100 may transmit the third electronic device 300. It can be determined whether to have control over.

When the management server 200 determines that the first electronic device 100 has no control over the third electronic device 300, the management server 200 may deny the control authority authentication to the first electronic device 100. [S178].

On the contrary, when the first electronic device 100 determines that the first electronic device 100 has control over the third electronic device 300, the management server 200 re-authenticates the control right to the first electronic device 100 according to the determination result. Can be done [S180].

The management server 200 may determine whether a conventionally generated control signal collides with a currently generated control signal [S192].

The management server 200 is, for example, both a conventional control signal for controlling the third electronic device 300 and a control signal for the first electronic device 100 currently controls the third electronic device 300. It may be determined whether the control signal is impossible. More specifically, the control signal generated by the fourth electronic device (not shown) and the control signal generated by the first electronic device 100 may be incompatible control signals for controlling the third electronic device 300. .

If the management server 200 determines that the signal is compatible, step S186 (shown in FIG. 9) is performed.

On the contrary, when it is determined that the management server 200 is an incompatible signal, the first electronic device 100 may control to output a notification message informing that the incompatible device is not compatible [S194].

Accordingly, the first electronic device 100 may notify the user that the control signal for controlling the third electronic device 300 collides with another control signal by the first electronic device 100.

The user may generate another control signal based on the notification message [S200].

In contrast, the user may request execution of the control signal despite the notification message [S196].

In this case, the first electronic device 100 requests the management server 200 to execute a control signal, and the management server 200 generates a control signal different from the previously generated control signal to the generator of the collision control signal. It can be informed that [S198].

In the above, when there are two or more control signals for the third electronic device 300 according to the exemplary embodiment described with reference to FIG. 10, and the control signals collide with each other, the user is prompted to recognize the collision of the control signals through the user notification.
