The at least one communication module includes WiFi, WiFi direct, WiFi hotspot, Bluetooth, and the like. In addition, other communication modules for performing communication with an access point (AP) may also be provided. In addition, although the NFC tag 140 is separately illustrated in FIG. 1, a communication module using the NFC tag may also be provided in the transceiver 110.

The control unit 120 may activate the NFC communication module when the NFC tag contacts the target terminal or is adjacent by a predetermined distance. And, it is possible to control the exchange of NFC tag information with the target terminal through the activated NFC communication module. The NFC tag may be provided at any location of each terminal or may be implemented as a single module in the transceiver. More specifically, the controller 120 may activate a wireless network for NFC communication. Then, a channel for content transmission and reception with a target terminal may be set, and a Digital Living Network Alliance (DLNA) device of the target terminal may be searched. The communication environment may be directly connected to the target terminal through the wireless network, or the communication environment may be connected through a repeater such as an AP.

2 is an exemplary diagram for data transmission and reception between a mobile terminal and a target terminal according to an embodiment of the present invention.

Hereinafter, a data transmission / reception process between a mobile terminal and a target terminal according to an embodiment of the present invention will be described with reference to FIG. 2 as follows.

First, when the source terminal requests and receives content from the target terminal, it is assumed that the source terminal is in an idle state and the target terminal is in a state in which the content is being executed.

In order to receive content such as images, pictures, etc. currently being executed by the target terminal, when the source terminal contacts the target terminal or approaches a predetermined distance, the NFC communication module may be activated for each terminal (S210). For example, when the source terminal contacts or approaches the target terminal, an NFC trigger event may be generated to activate the NFC communication module. Then, when the NFC communication module is activated between the source terminal and the target terminal, NFC tag information of the other terminal can be exchanged with each other (S212). The NFC tag information includes any one of pairing information of an NFC tag, Bluetooth pairing information of each terminal, and device information of a target terminal, and may be different depending on the type of the target terminal. When the NFC tag information is exchanged, the target terminal may search for at least one adjacent terminal in order to identify the terminals around it. And, when the NFC tag information is exchanged, it is possible to activate any one wireless communication module among at least one wireless communication module provided therein. Then, when NFC tag information is exchanged, the target terminal searches for at least one wireless communication module of the source terminal to activate the same wireless communication module as the source terminal. For example, when the NFC tag information of each other's terminal is read from each other, each terminal may acquire information for configuring the wireless network through this, and configure the wireless network with each other through the obtained information (S214). The wireless network may include short-range or long-range wireless communication such as WiFi, WiFi Direct, WiFi Hotspot, Bluetooth, and Ultra WideBand (UWB). As described above, when the wireless network is configured, each terminal searches for a Digital Living Network Alliance (DLNA) device of the other terminal. DLNA refers to the ability to share and play various media contents such as pictures, music, and videos, regardless of the manufacturer and product type, through the network between products through DLNA certification. In other words, the DLNA device is a device for transmitting and receiving data between a source terminal and a target terminal having a different product type and manufacturer. When the DLNA device is searched in the process (S214), the target terminal may provide the currently running content as streaming to the source terminal (S216). In addition, although the present embodiment discloses that the currently running content is provided as streaming, it is apparent that the present invention can also receive the currently running content in other ways.

3 is an exemplary view showing a process of receiving data from a target terminal that is playing data by a source terminal according to an embodiment of the present invention.

Hereinafter, a process of receiving content from a target terminal that is playing content by a source terminal according to an embodiment of the present invention will be described in detail with reference to FIG. 3 as follows.

First, it is assumed that the source terminal and the target terminal are terminals equipped with an NFC tag, and when the source terminal requests and receives content from the target terminal, the source terminal is in an idle state, and the target terminal is in a state in which the content is being executed. do.

In order to receive content such as video, music, photos, etc. currently being executed by the target terminal, when the source terminal contacts the target terminal or when it approaches a predetermined distance, each terminal leads NFC pairing information, The NFC communication module may be activated (S310). For example, when the source terminal contacts or approaches the target terminal, an NFC trigger event may be generated to activate the NFC communication module. Then, when the NFC communication module is activated between the source terminal and the target terminal, NFC tag information of the other terminal can be exchanged with each other (S312). In this way, by exchanging NFC tag information of each other's terminal, it is possible to grasp the current state of the other terminal. Thereafter, the target terminal scans a wireless communication capable of communicating to connect the channel with the source terminal, and when the source terminal is found, activates its communication module, and the source terminal activates an access point (AP) mode to activate the communication module. It can be (S314, S316). The communication module includes short-range or long-range wireless communication such as WiFi, WiFi Direct, WiFi Hotspot, Bluetooth, and Ultra WideBand (UWB). Then, the target terminal may attempt to connect the channel with the source terminal (S318). The channel connection is a pre-processing process of transmitting and receiving signaling to transmit and receive data between two terminals. Through this process, a channel is formed between two terminals to transmit and receive data. For example, the target terminal scans the wireless communication module (eg, WiFi communication module) of the source terminal, and the source terminal activates the WiFI hotspot mode. Thereafter, the target terminal accesses the WiFi hotspot mode activated by the source terminal. Thereafter, the source terminal may complete the connection with the target terminal (S320). As such, when a channel is formed between two terminals, each terminal can search for the DLNA device of the other terminal (S322). DLNA (Digital Living Network Alliance) is a contract that allows users to share and play various media contents regardless of manufacturer and product type through a wired or wireless network between products through DLNA certification. In other words, the source terminal and the target terminal according to the present invention are terminals authenticated to the DLNA, the source terminal is a DMS (Digital Media Server), and the target terminal is a DMR (Digital Media Renderer). However, this is only an example, and depending on whether content is transmitted or received, the source terminal may be a DMR, and the target terminal may be a DMS. When the DLNA device is searched between each terminal in the above process (S322), the target terminal transmits the content that it is currently playing to the source terminal, and the source terminal executes the corresponding execution program to play the received content, and then targets The content received from the terminal may be played (S324).

In FIG. 3, the terminal is described with respect to a terminal that executes content such as video, voice, and picture, but this is merely an example for convenience of description, and the source and target terminals according to the present invention are navigation and voice calls. It is obvious that it is applied to the terminal in use.

For example, when the source terminal is in a voice call, the target terminal assists the voice call through a microphone or speaker mounted on the vehicle, and when the Bluetooth function is a built-in terminal, the source terminal contacts the target terminal or a predetermined distance. As it gets closer, each terminal can read tag information for NFC communication. For example, the tag pairing information is read, and a wireless network is configured. The wireless network has short-range or long-distance wireless communication such as WiFi, WiFi Direct, WiFi hotspot, Bluetooth, and UWB (Ultra WideBand). In the case of a vehicle, Bluetooth may be mainly used. Then, when a wireless network via Bluetooth is connected, the user of the source terminal can continue a continuous call through the microphone and speaker mounted on the vehicle.

In addition, when the source terminal is in the state of running photo content and the target terminal is navigation, when the source terminal contacts the target terminal or approaches a predetermined distance, each terminal receives pairing information of the tag of the other terminal for NFC communication. Can lead. For example, the photo includes GPS information (Geo-tagging) of the place where the picture was taken, the target terminal leads such GPS information, the source terminal Bluetooth pairing information of the target terminal, the target terminal, for example, navigation Device information can be read. In this way, each terminal can transmit and receive tag information. Thereafter, the source terminal and the wireless network are set as the target terminal. Then, through the GPS information received from the source terminal, a place where a picture was taken may be searched for, and a path to a location or an adjacent preferred place or a place where a picture is taken may be searched for and displayed.

In addition, when the source terminal searches for maps or contacts by voice through the voice recognition module, and when the target terminal is navigation, when the source terminal contacts the target terminal or approaches a predetermined distance, each terminal is a counterpart for NFC communication. Pairing information of a terminal tag and navigation device information may be read. For example, if each terminal brings its tag close to the other terminal, each terminal can acquire information of the other terminal through NFC communication. In addition, the Bluetooth pairing information is used to activate a wireless network (eg, Bluetooth) of the terminal and perform an operation required for channel connection. In addition, the target terminal may receive voice search information of the source terminal through Bluetooth, search for a route to a region corresponding to the voice information, an adjacent preferred place or a corresponding region through the navigation search information, and display the search result. have. For example, if a specific region is searched on the map by voice search through the source terminal, the target terminal, that is, the navigation performs guidance of the searched specific region. If you search for a contact number (eg, my home) by voice, you can immediately guide the registered place registered in the navigation.

It can be transmitted (S414). Thereafter, when a response is received from the target terminal, the source terminal may attempt to pair with the target terminal to establish a wireless network with the target terminal (S416). Then, when a wireless network such as Bluetooth is connected, the source terminal forwards the voice data currently being called to the target terminal through the wireless network, and the user of the source terminal can continue the continuous call through the microphone and speaker mounted on the vehicle.
