Hereinafter, a Wi-Fi bridge system according to embodiments of the present invention and a Wi-Fi connection method using the system will be described in detail with reference to the accompanying drawings.

It should be understood that the following embodiments of the present invention are only for embodying the present invention and do not limit or limit the scope of the present invention. It will be understood by those of ordinary skill in the art that various changes in form and details may be made therein without departing from the spirit and scope of the present invention as defined by the following claims.

The present invention provides a software bridge module for WIFI and Bluetooth that enables data of a Wi-Fi to be transferred to Bluetooth, and a virtual Bluetooth connection is realized by Wi-Fi. .

For example, when considering a hands-free terminal mainly equipped with an automobile, the portable smart device is paired with a hands-free terminal mounted on a car. In addition, if the user desires to listen to music, the user can play the music application of his / her smart device and listen to the music on the car. If a call comes in while listening to music, the music is automatically stopped and the phone is switched to the call reception mode, and a call can be made to the soup phone through the hands-free terminal. In order to connect a smart device of another passenger to a hands-free device at the same time, it is necessary to cut off the pairing of the smart device of the user who is currently paired and to pair the smart device to be newly connected.

However, according to the present invention, if one smart device is connected to the handsfree terminal through Bluetooth pairing, the connected smart device can access the other smart devices by using its own Wi-Fi AP (Access Point) If it is possible, the music and the telephone of other smart devices connected to the WiFi may be able to initially transmit data through the smart device connected to the hands-free terminal. According to the present invention, since the present smart device can use Bluetooth and Wi-Fi at the same time without additional configuration, the above functions can be implemented by a software method.

In recent years, many PCs are often operated simultaneously. In many places, such as a developer or a control center, many PCs are driven simultaneously to monitor various types of data. One of the most uncomfortable of this is the need for input tools such as keyboard and mouse for each PC. This results in inconvenience in terms of space and efficiency. In this case, according to the present invention, it is possible to solve this problem by using the Bluetooth wireless keyboard and mouse and the Wi-Fi AP function and the router equipped with the Bluetooth.

According to the present invention, if all the PCs are connected to the Wi-Fi router with the Wi-Fi AP function, only the keyboard and the mouse are connected to the Bluetooth installed in the AP-function Wi-Fi router, and the rest is transmitted through the Wi- And the mouse signal. To do this, a Wi-Fi AP or router with a Bluetooth function is required. This Wi-Fi AP and router needs a bridge module software that converts TCP / IP data of a specific port into Bluetooth data. You'll also need a software driver that converts the incoming signal to a specific port on your PC to a mouse and keyboard input.

Bluetooth is defined as a hierarchical protocol structure such as a Core Protocol, a Cable Replacement Protocol, a Telephony Control Protocol, and an Adopted Protocol. The required protocol stacks are Link Management Protocol (LMP), Logical Link Control and Adaptation Protocol (L2CAP), and Service Discovery Protocol (SDP).

The Bluetooth profile defines the type, structure, and usage of the protocol used for each specific application based on the core protocol stack. Ultimately, a complete understanding of these core protocol stacks and profiles is required and implementation of bridge drivers with WiFi and Ethernet protocols based on them is required.

According to the present invention, first, a virtual Bluetooth application (virtual BT application) is required to allow a mobile device such as a smart device to perform a virtual Bluetooth operation. This allows you to make a call when you connect an existing Bluetooth device, or to automatically send a speaker to Bluetooth via Bluetooth when playing music. This virtual Bluetooth application is not directly connected, but when connected to WiFi, it obtains the information of the connected Bluetooth and makes necessary operation to operate using WiFi connection as if it is connected to Bluetooth.

According to the present invention, secondly, in a device in which a direct Bluetooth connection is made, a Wi-Fi-Bluetooth bridge application for connecting Wi-Fi and Bluetooth is required. It matches the incoming data to the promised port among the incoming data through the Wi-Fi to the information of Bluetooth and operates to actually communicate with the Bluetooth device using the required Bluetooth protocol stack.

The above two operations can be performed by mixing all the operations of several Smart devices at the end and transmitting them to the Bluetooth device.

The characteristic operation of the present invention as described above will be described below again with respect to each configuration.

Then, in the virtual Bluetooth application, the operation to be transmitted to the Bluetooth such as telephone or music is transmitted to the at least one terminal 10 equipped with the Wi-Fi router or the Wi-Fi-Bluetooth bridge using the specific port.

A virtual Bluetooth application is an application that enables virtual Bluetooth. When a virtual Bluetooth application is activated, it obtains information about a Bluetooth profile that is actually connected to the Wi-Fi bridge via a connected Wi-Fi connection. Based on the Bluetooth profile, it is possible to know which Bluetooth device 30 is connected and to perform an operation corresponding to the Bluetooth profile.

In a virtual Bluetooth application, the main operation is to transmit data to be transmitted through Bluetooth using the information of the Bluetooth profile through a Wi-Fi using a specific port.

At this time, the Wi-Fi router 20 and / or the at least one terminal 10 must be connected to the Ethernet to perform the role as an AP in advance. In the case of the Wi-Fi router 20, since the basic functions as a router, it is performed by turning on the power. In the case of at least one terminal 10, the hot spot function should be turned on. This allows at least one terminal 10 to function as an AP providing Internet access to a wireless local area network.

In this state, when the terminal 10 in which the virtual Bluetooth application is installed accesses the AP providing the Wi-Fi bridge function and operates the virtual Bluetooth application, the virtual Bluetooth application requests the information of the Bluetooth to the AP, The virtual Bluetooth application knows what kind of Bluetooth is connected and automatically transmits the virtual Bluetooth application to the AP using a specific port when the operation to transmit to the Bluetooth device 30 is performed in at least one terminal 10. [ After receiving the data, the AP transmits data to the Bluetooth device 30 using the appropriate Bluetooth protocol stack and profile.

FIG. 6 is a schematic diagram illustrating an operation scenario in which a plurality of PC inputs can be controlled through one Bluetooth keyboard and a mouse.

That is, in FIG. 6, a keyboard and a mouse are used as the Bluetooth device 30, and a PC is exemplarily used as at least one terminal 10.

 The Bluetooth keyboard and mouse are connected to a WiFi router (20) equipped with a WiFi-Bluetooth bridge. The PC with the virtual Bluetooth application and the virtual mouse and keyboard driver is also connected to the Wi-Fi router (20).

Each PC can set up a sequential ID number in a virtual Bluetooth application configuration and determine which PC has control of keyboard and mouse input based on this.

For example, when the first connection is made, the input control of the mouse cursor is given to the first PC, and when it goes out of the monitor screen coordinate, the control authority is passed to the PC set as the second ID. Control privileges on keyboard input can be dependent on mouse control privileges. In this way, according to the present invention, it is possible to provide a method of controlling a plurality of PCs with one Bluetooth input device. That is, according to the present invention, when there are a plurality of at least one terminal 10, the virtual Bluetooth application installed in each terminal 10 is used to control the Bluetooth device 30 of each terminal 10 Can be set.

As described above, according to the WiFi-Bluetooth bridge system of the present invention and the WiFi-Bluetooth connection method using the system, it is possible to connect a plurality of terminals 10 and the Bluetooth device 30 using a software bridge module Able to know.
