The handover requester refers to a device initiating a handover protocol by transmitting a handover request message to another NFC electronic device, and the handover selector configures a handover selection message as a response to the received handover request message. You can say the NFC device responding.

That is, the handover requester (i.e. handover request device) and the handover selector (i.e. handover select device) are relative concepts determined depending on whether to transmit a handover request message or a handover selection message. Accordingly, when the other electronic device 200 transmits the handover request message to the mobile terminal 100, the mobile terminal 100 is a handover selector, and the other electronic device 200 May be a handover requester.

The handover request message may include information on another communication module supported by the mobile terminal 100. [ 4, when the mobile terminal 100 supports Bluetooth and Wi-Fi, the handover request message includes information about Bluetooth and Wi-Fi supported by the mobile terminal 100. For example, .

The priority of the communication technology supported by the mobile terminal 100 used for the handover may be predetermined. For example, as shown in FIG. 4, the handover request message includes information about a communication module supporting a high priority communication technology at a front side, and for a communication module supporting a low priority communication technology. Information can be written later. Referring to the handover request message shown in FIG. 4, it can be seen that the information on the Wi-Fi communication module has a higher priority than the information on the Bluetooth communication module.

The other electronic device 200 receiving the handover request message may transmit a response to the handover request message to the mobile terminal 100 (S120). For example, the other electronic device 200 generates a handover selection message as an example of a response to the handover request message through an NFC link, and transmits the generated handover selection message to the mobile terminal 100 ).

The other electronic device 200 analyzes the handover request message to determine what is in the communication module included in the mobile terminal 100 and transmits the handover request message to the mobile terminal 100 The information about the communication module included in the communication module 200 may be provided. That is, the information on the communication module included in the handover selection message may include information on the communication module included in the other electronic device 200 among the communication modules included in the mobile terminal 100.

4, the controller 210 of the other electronic device 200 analyzes the received handover request message to transmit the Bluetooth communication module 118 and the Wi-Fi communication module 119 to the mobile terminal 100 And then transmits a handover selection message including information on the Bluetooth communication module 230 and the Wi-Fi communication module 240 included in the other electronic device 200 to the mobile terminal 100 .

The control unit 180 of the mobile terminal 100 analyzes the handover selection message and transmits the handover selection message to the Bluetooth communication module 230 of the other electronic device 200. [ And the Wi-Fi communication module 240 are included, and information about the Wi-Fi communication module 240 can be acquired.

Then, the mobile terminal 100 forms a communication link with communication modules included in the other electronic device 200 based on the obtained information, and then the other electronic device ( Data communication with 200 may be performed (S120).

For example, the controller 180 of the mobile terminal 100 may perform Bluetooth pairing with the other electronic device 200 to change the NFC communication link with the other electronic device 200 to a Bluetooth communication link . Accordingly, the mobile terminal 100 can switch the communication link with the other electronic device 200 from the NFC communication link to the Bluetooth communication link to continue communication according to the Bluetooth protocol.

As the communication link between the mobile terminal 100 and the other electronic device 200 is handed over from the NFC communication link to the Bluetooth communication link, the mobile terminal 100 and the other electronic device 200 are no longer in the state shown in FIG. 4 It is possible to perform data communication even if it is not located within the NFC communication range shown in FIG. 4A, and data can be exchanged at a higher transmission rate than the NFC link.

In other words, when the mobile terminal 100 is a smart phone, the user brings the smartphone near the other electronic device 200 and performs tagging with the other electronic device 200 to form an NFC link, By performing the over protocol, the communication means can be changed over the Bluetooth communication link. Then, even if the user takes out the smart phone out of the NFC communication range, the smart phone and the other electronic device 200 can continue data communication through the Bluetooth communication link.

The control unit 180 of the mobile terminal 100 performs a process of forming a WiFi communication link with another electronic device 200 in order to change an NFC communication link with the other electronic device 200 to a WiFi communication link, And may perform data communication with the other electronic device 200 through the formed WiFi communication link. Then, the mobile terminal 100 can perform data communication with the other electronic device 200 even outside the NFC communication range at a higher data transmission / reception rate than the NFC communication link.

At this time, when there are a plurality of changeable communication links from the NFC communication link, the control unit 180 of the mobile terminal 100 may perform a handover for only the selected communication link among the plurality of communication links, Lt; / RTI > In addition, when the controller 180 selects a communication link for performing a handover among a plurality of communication links, the controller 180 may select a communication link according to a predetermined priority order.

In the above, referring to FIGS. 3 and 4, the mobile terminal 100 according to the present invention establishes a communication link (eg, an NFC communication link) with a communication module included in another electronic device 200. The process of handing over to at least one of a communication link (for example, a Bluetooth communication link and a Wi-Fi communication link) with another communication module included in FIG.

Hereinafter, the mobile terminal 100 according to an embodiment of the present invention forms a communication link with a data storage element that stores information about a communication module included in another electronic device, and then replaces the formed communication link with the other. A process of handing over to a communication link with another communication module included in an electronic device will be described.

5 is a flowchart illustrating an operation of a mobile terminal according to an embodiment of the present invention, and FIG. 6 is a diagram illustrating tagging of the mobile terminal of FIG. 5.

Tagging may refer to an operation of approaching the mobile terminal 100 closer to the other device 200 by a predetermined distance or more. The user may make tagging by approaching another device 200 while holding the mobile terminal 100.

The other device 200 may be an electronic device capable of NFC communication or a tag capable of NFC communication. That is, an element capable of NFC communication with the mobile terminal 100 may be embedded in another electronic device or may be provided separately from the electronic device. In the latter case, a tag capable of NFC communication may be provided in the form of a card.

When the tagging is performed on another device 200, a step S20 of forming a short range communication link with another device 200 and a step S30 of acquiring data through the short range communication link may be performed.

The short range communication link may be a communication link using a short range communication module (114 in FIG. 1) of the mobile terminal. The near field communication link may be an NFC communication link. Once the NFC communication link is established, data can be exchanged through it. Alternatively, data may be transmitted from the other device 200 to the mobile terminal 100 through the NFC communication link.

The exchange and / or transfer of data over a near field communication link may be performed based on a particular near field communication protocol. As described above, the short range communication may be performed in a Bluetooth, infrared, UWB, Zig-Bee, or the like manner. However, for the sake of understanding, the following presupposes the case of near field communication using NFC.

When the NFC method performs short range communication, the mobile terminal 100 and the other device 200 may exchange and / or transmit data according to NDEF (NFC Data Exchange Format). Data acquired by the mobile terminal 100 from another device 200 according to an embodiment of the present invention may be a data format complying with NDEF. However, reference information may be added to a certain field of the NDEF.

The reference information may be information that serves as a reference for limiting an output range of data transmitted using short-range communication. That is, it means that the transmitted data may be information that only a specific range of people can selectively view. For example, if the transmitted data includes adult information, the data may be restricted to adults only. The standard information may include various standards in addition to age, which will be described in detail in the corresponding section.

Acquiring user information of the mobile terminal 100 may be performed (S40).

For example, if the age for viewing the data based on the reference information is 20 years old and the owner of the mobile terminal 100 is 15 years old according to the user information, the user information may not satisfy the reference information. have.

If the user information satisfies the reference information, step S60 of outputting the acquired data may be performed.

The fact that the user information satisfies the reference information may be a fact that a person who is entitled to view the data is operating the mobile terminal 100. Therefore, the controller 180 of FIG. 1 may output the acquired data without limitation.

Outputting data may mean using data corresponding to attributes of data. For example, if the data is a character and / or an image, the data may be displayed through the display unit 151 of FIG. 1, and if the data is a sound, sound may be generated through the sound output unit 152 of FIG. 1. have. If the data is a URL address, information corresponding to the address may be obtained through the wireless communication unit (110 of FIG. 1).

If the user information does not satisfy the reference information, a step of outputting the fact that the user information is not satisfied (S70) and discarding the corresponding data (S80) may proceed.

The fact that the user information does not satisfy the reference information may mean that a person who is not entitled to view the data is operating the mobile terminal 100. Therefore, the controller 180 of FIG. 1 may discard the acquired data without outputting it. In addition, the user can be notified by outputting such a fact to the display unit 151 of FIG.

The controller (180 of FIG. 1) of the mobile terminal 100 may obtain user information (S40). The user information may be located in the memory of the mobile terminal. Furthermore, if necessary, the controller 180 of FIG. 1 may obtain user information from an external device. For example, it means that information about a user of the mobile terminal 100 can be obtained from a user information management server.

The process of comparing the user information and the reference information may be performed (S50).

If the user information satisfies the reference information, the process of outputting the acquired data may proceed (S60).

The controller (180 of FIG. 1) of the mobile terminal 100 may proceed to request related information to the wireless Internet server 300 (S62) and to obtain related information (S64).

The data obtained from the near field communication device 200 may be data about a source of information. For example, it may be a URL address. The controller (180 of FIG. 1) may request related information from the wireless Internet server 300 based on the obtained URL address.
