Description

[0001] BLUETOOTH PAIRING SYSTEM [0002]

[0001] The present invention relates to a Bluetooth pairing system using NFC, and more particularly to a first terminal including a reader unit for reading information using NFC (Near Field Communication) and a controller for discriminating and determining the read information by doing,

When the information determined by the control unit requests pairing of the first and second terminals, the first or second communication unit can directly connect the Bluetooth according to the information, thereby directly connecting the Bluetooth pairing between the terminals, thereby reducing unnecessary search time. In addition, when performing a pairing between the first terminal and the second terminal, it is possible to reduce the number of lists to be searched and selected, and the user can easily pair the terminals with each other or touch them easily so that the terminals can be quickly paired with each other. The present invention relates to a Bluetooth pairing system using an NFC.

Generally, when a mobile communication terminal including a Bluetooth device is paired with another Bluetooth device, a peripheral device is searched, a PIN code is exchanged, and a connection is established. When pairing with a Bluetooth device other than the currently paired Bluetooth device, the process of inputting the PIN code by the user must be performed. In this case, when the Bluetooth device is to communicate with the Bluetooth device, Or the process of inputting the password must be manually entered by the user.

In order to reduce such inconvenience, devices capable of automatically connecting when a mobile communication terminal is paired with another Bluetooth device are being developed. There has also been developed a technique of reading data from a tag using RFID (Radio Frequency Identification) and transferring the read data to the mobile communication terminal at the same time.

In addition, current mobile communication terminals use the Near Field Communication (NFC) service among the RFID technologies. The NFC service is mainly used for short-distance communication (within 10 km) in Europe. It is used for data communication, and data can be read from a tag with a mobile communication terminal equipped with an NFC chip, thereby achieving a connection with excellent speed and security.

However, the NFC service needs to be contacted or non-contacted at a considerably short distance, and must be close to a short distance to maintain continuous connection or pairing, and has a slower transmission rate than Bluetooth communication even when the connection is maintained.

Thus, many prior art techniques for such near-field technologies have been proposed,

Prior Art No. 10-0827813 (registered on April 29, 2008) discloses a method for pairing Bluetooth devices using tags and a Bluetooth device for the same, including a tag reader for reading information of the contactless tag and a slave Bluetooth device A method of pairing a master Bluetooth device including a Bluetooth connection controller for pairing with a slave Bluetooth device, the method comprising: a first step of the tag reader reading a tag ID received from a non-contact tag; A second step of the tag reader transmitting the slave Bluetooth device information to the Bluetooth connection controller when the tag ID includes information of the slave Bluetooth device; A third step of the Bluetooth connection controller paired with the slave Bluetooth device using the slave Bluetooth device information transmitted from the tag reader; A pairing method of a Bluetooth device using a tag that allows a Bluetooth device to be connected to be directly paired with a Bluetooth device without exposing the PIN information of the Bluetooth device to be connected, Device,

However, in the related art, the tag reader and the Bluetooth connection controller are configured in the master Bluetooth device, so that a process of directly searching for the slave Bluetooth device without a contactless tag necessarily arises. In addition, if the tag reader of the master Bluetooth device is inactivated, there is a problem that the slave Bluetooth device must go through a search process for an existing Bluetooth connection.

In addition, Patent Registration No. 10-1081535 entitled " Communication method and apparatus of Bluetooth mobile communication terminal using RFID "relates to wireless data communication between a Bluetooth mobile communication terminal using a Bluetooth technology and a Bluetooth device, The present invention relates to a method and an apparatus for automatically performing Bluetooth data communication using a Bluetooth communication device. A basic technical idea is to mount an RFID reader in a Bluetooth mobile communication terminal and attach an RFID tag to a Bluetooth device to implement automatic pairing / connection or data selection / transmission through the information of the RFID tag. According to the present invention, pairing and connection are automatically performed between a Bluetooth mobile communication terminal and a Bluetooth device without a manual registration process, and data transferred from a Bluetooth mobile device to a Bluetooth device or data embedded in the mobile device There is provided a communication method and apparatus for a Bluetooth mobile communication terminal using an FID, in which an operation of transmitting data from the Bluetooth device to the Bluetooth mobile communication terminal is automatically performed.

In the conventional technology, when the RFID reader is installed in the Bluetooth mobile communication terminal and the power of the terminal is disconnected or the battery is consumed, the RFID reader is inactivated and there is a limit to depend on the power supply of the terminal. There is a problem that it is inconvenient to store the information in advance in the tag.

In addition, there is a patent registration No. 10-0917922 entitled " Method and system for providing wireless Internet service using Bluetooth dongle ", which discloses a method for setting a wireless channel for transmitting / receiving data related to a wireless Internet service and a mobile communication terminal capable of Bluetooth communication A Bluetooth dongle, a terminal connected to the wired Internet and connected to the Bluetooth dongle to provide routing information of a destination for providing a wireless Internet service to the mobile terminal, a VPN connected to the terminal through the wired Internet, And a wired / wireless gateway for transmitting / receiving wireless Internet service related data between the mobile communication terminal and the application server using a virtual private network (VPN) tunnel.

However, since the registered patent serves as a connection material for providing the wireless Internet while the wired Internet is connected, there is a problem that the mobile communication terminal can not be connected to the device connected to the wired Internet. In addition, when a wireless Internet is connected using a Bluetooth dongle, there is a problem that an unsolicited terminal is connected and is vulnerable to security.

Further, Japanese Patent Application Laid-Open No. 10-2010-0053986 discloses a method for pairing a Bluetooth device with a Bluetooth device, Activating a Bluetooth function of the mobile terminal; (b) searching for a Bluetooth device within the distance that the terminal supports the Bluetooth function; (c) receiving the name information of the Bluetooth device from the searched Bluetooth device when the Bluetooth device is searched, (d) comparing the name information stored in the bluetooth list with the name information stored in the bluetooth list Determining whether the name information of the Bluetooth device is the same; And (e) automatically pairing the terminal with the Bluetooth device having the same name information as the name information stored in the Bluetooth list, wherein the Bluetooth list includes name information of the Bluetooth device that has been paired with the terminal According to an automatic pairing method between a Bluetooth device and a terminal, a Bluetooth device capable of automatically pairing a Bluetooth device and a terminal through a simple process, an automatic pairing method between terminals, and a terminal including a Bluetooth module are presented.

However, the above-mentioned patent discloses that a search step between a Bluetooth device and a terminal is essentially included, which takes a long time to search. The already searched terminals show a relatively quick search result, but there is a problem in that it is necessary to wait for long time to make a pairing connection between the devices in a city where many bluetooth devices exist.

According to an aspect of the present invention, there is provided a mobile communication system including a first terminal including a first field portion capable of NFC communication and a second field portion, the information being read by the second terminal, The second communication unit can directly connect to the first communication unit via the Bluetooth, so that the NFC can be directly paired without a separate search for the Bluetooth connection between the first terminal and the second terminal, To provide a Bluetooth pairing system.
