Description

Method and device for registering a wireless device in a wireless communication system {METHOD AND APPARATUS FOR REGISTERING WIRELESS DEVICE IN WIRELESS COMMUNICATION SYSTEM}

The present invention relates to a method and apparatus for registering a wireless device in a wireless communication system.

Recently, as the frequency of use of wireless communication increases, it is necessary to connect a new wireless communication device to a communication network. In addition, there is a case where a temporary connection between wireless devices is required based on a wireless communication technology. In this case, pairing should be performed between the wireless devices.

In a conventional wireless communication system, pairing may be performed by an application installation process and a device registration / authentication process. The application installation process represents a process in which a user searches for and downloads an application for pairing distributed by an operator and downloads it or is provided from a separate provider.

The device registration / authentication process minimizes power to recognize a wireless device for pairing, registers a wireless device by receiving a personal identification number (PIN) code, and blocks registration of another wireless device during pairing. And the process of performing encrypted communication through authentication key exchange. Referring to the device registration / authentication process as described above in detail.

First, a wireless device (hereinafter, referred to as a 'device registration wireless device') to register a device proceeds with registration only for wireless devices in close proximity to minimize transmission power. Accordingly, the device registration wireless device should move to a location adjacent to the wireless device to be registered, or the wireless device to perform a registration procedure should move to a location adjacent to the device registration wireless device. As such, two wireless devices must be adjacent to each other by a user for pairing between two wireless devices. Therefore, the existing device registration method may be limited to the method by the user because the active intervention of the user is absolutely necessary.

On the other hand, when the two wireless devices are in an adjacent location, a communication environment for communication between the two wireless devices is created and a PIN code may be used for encrypted communication. The device registration wireless device provides a PIN code provided from a randomly generated or associated system to the wireless device, and determines a wireless device to register a wireless device that has input a PIN code corresponding to the provided PIN code as a wireless device to register. You can proceed.

The device registration wireless device prevents any devices from intervening during the registration procedure by ignoring all other devices accessed for a preset time when the registration procedure is in progress.

Also, for security purposes, two wireless devices that are not open before pairing use separate wired communications (such as universal asynchronous receiver / transmitter) and closed wireless communications (such as IrDA (infrared data association)). After performing the mutual key exchange necessary for authentication, the registration process through the authentication process can be performed. The two wireless devices may perform a registration procedure through encrypted secure communication using peer-to-peer (P2P) communication of near field communication (NFC).

Meanwhile, in the above pairing scheme, even if the pairing process is normally performed, another wireless device adjacent to the device registration wireless device may be registered instead of the wireless device to be registered by the user. In addition, the pairing method has to be handled separately from the installation of the application and the device registration without being processed as a single process, and the setting for pairing is complicated because multiple items of an identifier (ID) and a password are required. There is.

The wireless device 100 performs Wi-Fi communication and may include a two-dimensional recognition code 105 including device information and the like. The recognition code 105 may be, for example, a QR (quick response) code or the like. Hereinafter, for convenience of description, the recognition code 105 will be referred to as a QR code.

In the first embodiment of the present disclosure, the QR code 105 may include connection type information indicating a wireless communication type such as Wi-Fi, operation mode information that the terminal 110 should enter in the registration process, and Wi. -Fi MAC address, service set identifier (SSID) and password to be used for tethering connection, uniform resource identifier (URI) information for downloading of application, etc. It may include. The above information may be stored encrypted in the QR code 105, the URI information may be recorded according to the QR standard.

The terminal 110 is a device capable of performing Wi-Fi communication and acquires the information included in the QR code 105 by scanning the QR code 105. The terminal 110 enters a tethering mode based on the information obtained from the QR code 105 so that the registration procedure for the wireless device 100 can proceed.

The AP 120 is connected to the home server 130 to communicate with an external network. For example, when the terminal 110 transmits URI information, the AP 120 may transmit an application corresponding to the URI to the terminal 110.

The home server 130 is connected to the external network and the AP 120 to manage information on various devices on the home network.

Hereinafter, a registration process of a wireless device in the wireless communication system as shown in FIG. 1 will be described with reference to FIG. 2.

Here, the wireless device 100 may transmit a connection request message immediately after recognizing the terminal 110, but notifies the user by using a display or a voice signal that the terminal 110 has been recognized, and then, from the user. The connection request message may be transmitted by receiving a separate input.

When the connection request message is received, the terminal 110 performs a connection operation with the wireless device 100 through Wi-Fi in step 210. In this case, since the terminal 110 operates as an AP, the terminal 110 may be connected to not only the wireless device 100 but also a plurality of wireless devices. Therefore, the terminal 110 should detect the wireless device 100 that the terminal 110 intends to register among a plurality of wireless devices connected to the terminal 110. To this end, the terminal 110 detects the wireless device 100 among a plurality of wireless devices connected to the terminal 110 based on the Wi-Fi MAC address in step 212.

For example, the terminal 110 uses a simple service discovery protocol (SSDP) / multicast domain name system (mDNS) or another discovery protocol to transmit a request signal for wireless device discovery to the plurality of wireless devices. And then broadcast a response to it. In this case, the terminal 110 may detect, as the wireless device 100, a wireless device that has transmitted a response signal including the same Wi-Fi MAC address as the Wi-Fi MAC address known to the terminal 110.
