Here, the short-range communication link refers to a link formed when the short-range communication module 114 of the first electronic device 100 and the short-range communication module of the second electronic device approach each other within a predetermined distance.

More specifically, referring to FIG. 2 (a), the short distance communication module 120 of the first electronic device 100 has a communication radius of R1 and the short distance communication module 220 of the second electronic device 200 has a communication radius of R2 Lt; / RTI > As shown in Fig. 2 (a), when the second electronic device is not included in the communication radius R1 of the first electronic device, a short-range communication link is not formed.

In this case, a short-distance communication link is formed between the first electronic device 100 and the second electronic device 200 because the first electronic device 100 and the second electronic device 200 are located within a predetermined communication radius .

More specifically, when the short distance communication module 120 of the first electronic device 100 emits an electromagnetic wave to the surroundings, the second electronic device 200 is located within a predetermined distance from the first electronic device 100 The second electronic device 200 recognizes the electromagnetic wave radiated from the first electronic device 100.

[ Thereby, a short-distance communication link is formed between the first electronic device 100 and the second electronic device 200.

At this time, the second electronic device 200 may transmit a response message to the first electronic device 100 using the electromagnetic wave obtained from the short-range communication module 120 of the first electronic device 100, The device 200 may transmit a response message to the first electronic device 100 using its own energy. Hereinafter, the second electronic device 200 refers to a passive mode when electromagnetic energy obtained from the first electronic device 100 is used in a response message transmission, Quot; active mode " will be referred to as " active mode ".

Hereinafter, the process of forming a short-range communication link by bringing both devices close to each other will be referred to as tagging.

As described above, the short-range communication link according to the embodiment of the present invention has been described. Hereinafter, a handover protocol using a short-range communication link will be described.

The first electronic device 100 forms an NFC link with another electronic device through the NFC communication module 114, forms a communication link with the NFC link and continuously communicates data with the other electronic device Can be performed. In this document, the process of forming an alternative communication link using an alternative communication carrier after the first and second electronic devices 100 and 200 form an NFC link will be referred to as a handover protocol.

The handover protocol is a protocol that takes advantage of the fact that a short-range communication link is shorter and faster than other communication links, while a communication radius is shorter and data communication speed is slower than other communication links. That is, the handover protocol may be configured to establish an initial link establishment with a local communication link and to establish an alternative communication link, e.g., a Wi-Fi communication link based on the established local communication link, can do.

Hereinafter, a sequence of the handover protocol will be described with reference to FIG.

Referring to FIG. 3, the handover protocol includes a handover request message transmission step S100, a handover selection message reception step S110, an alternative communication link step S110, ≪ RTI ID = 0.0 > [S120]. ≪ / RTI > At this time, data transmission / reception is performed through the short-range communication link in steps S100 and S110, and an alternative communication link is formed in step S120, thereby completing the handover protocol. Hereinafter, each step will be described in detail.

The first electronic device 100 may transmit a handover request message to the second electronic device 200 (S110).

At this time, the first electronic device 100 can transmit a handover request message to the second electronic device 200 via the local communication link.

Here, the first electronic device 100 may have a status of a handover requester, and the second electronic device 200 may have a status of a handover selector. The handover requestor refers to a device that initiates a handover protocol by transmitting a handover request message to another NFC electronic device. The handover selector configures a handover selection message as a response to the received handover request message You can say the NFC device that responds. That is, the handover requestor (i.e., the handover requesting device) and the handover selector (i.e., the handover selection device) are relative to each other according to whether the handover request message is transmitted or the handover selection message is transmitted. Accordingly, when the second electronic device 200 transmits a handover request message to the first electronic device 100, the first electronic device 100 is a handover selector, The second electronic device 200 may be a handover requester.

The handover request message may include information related to an alternative communication carrier supported by the first electronic device 100. [ For example, as shown in FIG. 1, since the first electronic device 100 supports Zigbee and Wi-Fi, the handover request message includes a Zigbee and a Wi- Fi. ≪ / RTI >

A plurality of alternative communication carriers may be assigned priorities. The handover request message may include information on an alternative communication carrier having a higher priority in the front side and information on an alternative communication carrier having a lower priority in the rear side. Hereinafter, for the sake of convenience of explanation, it is assumed that Wi-Fi has priority over Zigbee.

The specific data format of the handover request message will be described later.

Upon receiving the handover request message, the second electronic device 200 may transmit a response to the handover request message to the first electronic device 100 (S110).

For example, the second electronic device 200 generates a handover selection message as an example of a response to the handover request message, and transmits the generated handover selection message to the second electronic device 200 via the NFC link, 1 < / RTI >

The second electronic device 200 determines which of the alternative communication carriers included in the handover request message is supported by the second electronic device 200, And may provide the device 100 with information about an alternative communication carrier that the second electronic device 200 supports. That is, the alternative communication carrier included in the handover selection message may include information on the alternative communication carrier supported by the second electronic device 200 among the alternative communication carriers supported by the first electronic device 100 have.

Hereinafter, for convenience of explanation, the second electronic device 200 supports both the Wi-Fi and the Zigbee, which are alternative communication carriers included in the handover request message, but the prioritized Wi-Fi is used as an alternative communication carrier And the description will be continued.

The specific data format of the handover selection message will be described later.

The first electronic device 100 may perform data communication with the second electronic device 200 via the alternative communication carrier [S130].

To this end, the first electronic device 100 receives the handover selection message from the second electronic device 200 to obtain information on the alternative communication carrier supported by the second electronic device 200 . For example, the first electronic device 100 can confirm that the acquired alternative communication carrier supported by the second electronic device 200 is Wi-Fi.

Therefore, the first electronic device 100 can perform the handover to the other carrier from the second electronic device 200 based on the information obtained according to the transmission / reception of the handover request message and the handover selection message A series of processes can be performed.

As the link between the first electronic device 100 and the second electronic device 200 is handed over from NFC to Wi-Fi, the first electronic device 100 and the second electronic device 200 The data communication becomes possible even if it is not located within the NFC communication range R1 shown in FIG. 2, and an advantage that data can be exchanged at a higher transmission rate than the NFC link can be obtained.

In other words, if the first electronic device 100 is a smart phone, the user brings the smart phone near the smart pad 200, which is the second electronic device 200, and taches the second electronic device 200, By forming an NFC link and performing a handover protocol, a link can be formed with Wi-Fi. Once the Wi-Fi link is established, even if the user takes the first electronic device out of the NFC coverage, the first electronic device 100 and the second electronic device 200 can continue data communication over Wi-Fi .

The handover protocol according to an embodiment of the present invention has been described above. Hereinafter, a handover request message and a handover selection message used in the handover protocol will be described in detail.

FIG. 4 illustrates an example of a handover request message according to an embodiment of the present invention.

The handover request message may include a handover request record and one or more NDEF records. For example, the handover request message may start with a handover request record and end with an NDEF record.

The handover request record may include at least one of information indicating a handover request message and version information indicating a handover request message.

The NDEF record may include information about an alternate communication carrier.

More specifically, the information contained in the NDEF record may include information for identifying an alternate communication link. That is, the handover carrier record may provide the handover selection device with information on what the alternative communication means supported by the handover requesting device is. In this document, an NDEF record including information for identifying an alternate communication link will be referred to as a handover carrier record.

Meanwhile, the information included in the NDEF record may include configuration information for forming an alternative communication link. In this document, an NDEF record including configuration information necessary for forming an alternate communication link, for example, a password, an address and the like necessary for link formation, will be referred to as a carrier configuration record.

Meanwhile, the handover request message may start with a handover request record including a flag set to a message start (MB), and end with an NDEF record having a flag set to a message end (ME).

Since the handover request message must include at least one alternative communication carrier, the MB and ME flags can not have all the records set.

FIG. 5 illustrates an example of a handover selection message according to an embodiment of the present invention.

As described above with reference to FIG. 3, the handover selection message is transmitted to an alternative communication carrier supported by the handover selection device among the alternative communication carriers included in the handover request message received from the handover requesting device May be used to provide the handover request message to the handover requesting device.

Referring to the upper part of FIG. 5, the structure of the handover selection message may be the same as the structure of the handover request message described with reference to FIG.

The handover selection message may also include a handover selection record and an NDEF record corresponding to the handover request message.

The handover selection record may include information corresponding to the handover request record. That is, the handover selection record may include at least one of information indicating the handover selection message and version information among the handover request and selection messages.

The NDEF record may include information on alternate communication carriers (i.e., carrier configuration records). A more detailed description will be given later with reference to Fig.

Also, referring to the bottom of FIG. 5, the handover selection message may include a single record in which both a message start (MB) and a message end (ME) are all set. That is, in this case, there may be no alternative communication carrier supported by the handover selector among the alternative communication carriers supported by the handover requestor.

FIG. 6 shows information of an NDEF record included in a handover selection message when an alternative communication carrier according to an embodiment of the present invention is Wi-Fi.

If the alternative communication carrier is Wi-Fi, the NDEF record of the handover selection message includes environment setting information necessary for accessing Wi-Fi, for example, a service set identifier (SSID), an authentication type, And may include at least one of an encryption type, a network key, a MAC address, and information on a channel number.

Upon receiving the handover selection message including the NDEF, the first electronic device 100 transmits an alternative communication carrier provided by the handover selection device, for example, You can connect to Wi-Fi.

The handover request message and the handover selection message have been described in detail with reference to FIGS. In the above description, it is assumed that the alternative communication carrier is Wi-Fi. However, even when the alternative communication carrier is Bluetooth, Zigbee, etc., the handover request message and the handover selection message according to an embodiment of the present invention can be applied Of course it is.

Hereinafter, an operation method according to an embodiment of the present invention will be described with reference to FIG. 7 based on the embodiments described with reference to FIGS. 1 to 6. FIG.

The method of operating an electronic device according to an embodiment of the present invention is a method of joining a specific network to a specific network when a specific command is received with respect to an arbitrary content in the first electronic device 100, Provides a list of electronic devices that can perform a specific command. At this time, as a means for the first electronic device 100 to join to a specific network, a handover protocol can be used.

For this, referring to FIG. 7, an operation method of an electronic device according to an embodiment of the present invention includes a step S200 for receiving a content, a step S210 for inputting a specific command for the selected content, A step S230 of providing a list of electronic devices capable of performing the specific command among the electronic devices belonging to a specific network, a step S240 of selecting a specific electronic device in the list, And performing the specific command [S250]. Hereinafter, each step will be described in detail.

The first electronic device 100 can select a specific content (S200).

In this document, contents may include various computer works such as moving images, still images, broadcast contents, and the scope of contents is not limited to the above-mentioned examples.

In this document, the content may be independent of the stored location. This means that the content in this document includes not only the content stored in the memory 160 of the first electronic device 100 but also the content on the external server. One example of content stored on an external server may include content stored on a Digital Living Network Alliance (DLNA) network or Apple Bonjour network.

The first electronic device 100 can receive a specific content in various ways. Hereinafter, an example of a method in which the first electronic device 100 selects a specific content will be described with reference to FIG.

A user can cause the first electronic device 100 to output a list of contents through a browse action, and select a particular content, for example, Movie 1, desired by the first electronic device 100.

Thus, the first electronic device 100 receives a selection of a specific content.

Hereinafter, for convenience of explanation, it is assumed that the movie 1 is selected as the specific content in step S200, and the movie 1 is stored in the memory 160 of the first electronic device 100, and the description will be continued.

Referring again to FIG. 7, the first electronic device 100 can receive a specific command for the selected content (S210).

Specific instructions may include any actions that may be performed on the selected content. For example, a specific command may include copy, move, delete, output (i.e., play), output from an external device, print, and the like.

In this document, output from an external device refers to outputting a content selected from an electronic device other than the first electronic device 100 whose content has been selected.

In addition, the specific command may differ depending on the attribute of the selected content. For example, when the attribute of the selected content is a movie, the command " playback " is valid, but the command " print " Conversely, when the selected content is text, the command of printing and opening is valid, but the command of reproduction may not be valid. Thus, the first electronic device 100 may provide a list of specific instructions that may be assigned to the content in consideration of the attributes of the content.

Reference will be made to Fig. 9 to more specifically describe step S210.

9 is a diagram for explaining a specific command input according to the first embodiment of the present invention.

That is, as shown in FIG. 9, the first electronic device 100 has a function of copying (icon1), deletion (icon2), output (icon3) And an icon such as an icon 4 can be output through the display 151.

At this time, it is assumed that the first electronic device 100 has selected the output (icon4) from the external electronic device by the user, and the description will be continued.

Meanwhile, step S200 and step S210 according to an embodiment of the present invention are not continuous steps. In other words, the step S210 may proceed ahead, and the step S200 may proceed later.

Then, the first electronic device 100 can enter a specific network (S220).

The first electronic device 100 must be connected to an external electronic device because the selected specific instruction is to be processed in the external electronic device. Thus, the first electronic device 100 joins the specific network to output the selected content from the external electronic device.

In this document, a specific network is not limited to a network connection means. That is, it is needless to say that the specific network may be configured as a connection means for an existing Wi-Fi AP (access point) or may be configured as a connection means to be developed in the future.

For convenience of explanation, it is assumed that the network shown in Fig. 10 is an example of a specific network.

Each step will be described in detail below.

The first electronic device 100 may determine whether there is an external electronic device currently connected (S300).

Determining whether there is an external electronic device currently connected in this document may have the same meaning as determining whether the first electronic device 100 is connected to a specific network.

That is, the first electronic device 100 judges whether or not the electronic device to perform the previously selected specific command is connected.

If it is determined that the external electronic device is connected as a result of the determination of the first electronic device 100, the process shown in FIG. 11 may be skipped and the process may proceed to step S230 of FIG.

Otherwise, if it is determined that the external electronic device is not connected as a result of the determination of the first electronic device 100, step S310 may be performed.

That is, the first electronic device 100 may request connection to an external electronic device (S310).

The first electronic device 100 requests a connection to an external electronic device to join the network. More specifically, by subscribing to a specific network by requesting a connection to another electronic device registered in the specific network of the first electronic device 100. [

The selection menu may provide a guide for the user to select how the first electronic device 100 is to be joined to a particular network.

The network setting (icon5) may be an icon that provides a guide for the user to join the network using an existing communication link setting method.

The connection to the NFC (icon6) may provide a guide for the first electronic device 100 to be joined to a specific network through the short-range communication module of the first electronic device 100. More specifically, when the icon 6 is selected, the first electronic device 100 can join the specific network by performing the handover protocol described above with reference to FIG.

Hereinafter, the case where the user selects icon 6 corresponding to the NFC connection will be described.

When the user selects icon 6, the first electronic device 100 may provide a guide to form an NFC link as shown in FIG. 12 (b).

Accordingly, the user can tag a first electronic device 100 and a specific electronic device to form a short-distance communication link between the first electronic device 100 and a specific electronic device. The definition of the short-range communication link and the method of forming the short-range communication link are the same as those described with reference to FIG. 2, and the description will be omitted.

For example, the first electronic device 100 may prioritize a network having many electronic devices connected to the second electronic device 200 to recommend prioritized communication link schemes. More specifically, when the second electronic device 200 is connected to another electronic device via Wi-Fi rather than Zigbee, the first electronic device 100 recommends a Wi-Fi communication link method through a handover protocol You can do it. In addition, the first electronic device 100 assigns a priority to a network having many electronic devices capable of performing the specific command among the electronic devices connected to the second electronic device 200, and recommends a priority-assigned communication link method can do. More specifically, among the electronic devices connected to the second electronic device 200 through the Zigbee, there are two electronic devices capable of performing the specific command, and among the electronic devices connected by Wi-Fi, an electronic device 5, the first electronic device 100 can recommend Wi-Fi as a communication link method among Zigbee and Wi-Fi.

Hereinafter, for convenience of explanation, it is assumed that a user requests a Wi-Fi connection (icon 7) through a handover protocol.
