Description

Electronic device and wireless network connection method

The present invention relates generally to wireless network connection technologies, and more particularly to wireless network connection techniques for performing an Ad Hoc connection by pressing a button combination using an input device.

In this era of information explosion, information transmission has become an indispensable part of daily life, and information transmission can be achieved mainly through wired networks and wireless communication. Among them, wireless communication has become the focus of modern technology development because it saves the cost and time of setting up the network route and exceeds the limitation of ground obstacles. Under the specification of wireless communication 802.11, the Institute of Electrical and Electronics Engineers (IEEE) defines two communication modes: Ad hoc mode and Base station mode (Infrastructure). In summary, the base station mode means that multiple terminal devices (such as computers) communicate by means of an access point (AP) or a base station; and the peer-to-peer mode means that multiple terminal devices are not accessed by an access point or base. Directly communicate with each other.

The birth of the wireless network card has made the user get rid of the trouble of the wired wire and made the mobile high-speed Internet possible. The function of the wireless network card is not only to connect to the wireless access point (AP), but also to connect multiple computers through a wireless network card, play games, share files, or even use a computer as a route. , allowing other computers to connect to the Internet through the computer.

At present, the wireless network card is relatively simple when connecting existing wireless signals, and for the other functions of the wireless network card, even a simple connection of two Computers also require many steps, and these steps are difficult for people who are not familiar with computers. Not to mention the transfer of files and the sharing of network resources. For some wireless connectivity software that comes with many manufacturers, most of them just integrate some functions together, and people still need cumbersome operations to complete the desired results.

In view of the above prior art problems, the present invention provides a wireless network connection technology that requires only a combination of input devices to perform a point-to-point mode (Ad Hoc) connection wireless network connection technology.

An embodiment of the present invention provides an electronic device, an Ad Hoc connection for a wireless network, including: an input device; a processor coupled to the input device, by the user pressing the above Inputting a button combination to generate a corresponding one of the output signals; a first wireless network card, according to the output signal, scanning whether a second electronic device sends a service setting identifier corresponding to the button combination and an IP address And connecting to a second electronic device according to a scan result; and a display device, when the connection with the second electronic device is successful, is used to display an icon, wherein when the connection is successful, the user can release The above key combination pressed.

According to an embodiment of the present invention, a wireless network connection method is provided. The first electronic device and the second electronic device are provided by: pressing a button combination of one of the input devices of the first electronic device to generate Corresponding to one of the output signals, according to the output signal, scanning whether there is a service setting identification code and an IP address corresponding to the one of the key combinations sent by the second electronic device, and the second electronic device is used according to a scan result. Performing an Ad Hoc connection; when the Ad Hoc connection is successful, displaying an icon on the first electronic device and the second electronic device respectively; and releasing the pressed key combination .

1 is a block diagram of a first electronic device 100 according to an embodiment of the invention, wherein the first electronic device 100 is adapted for a point-to-point mode (Ad Hoc) connection of a wireless network.

The encryption and re-broadcast of the set service setting identifier is performed by the first wireless network card 130, and the set service identification code is re-searched, and the connection is completed by using the key and the second electronic device 200.

According to the above embodiment, if the first wireless network card 130 does not scan the service setting identification code (SSID) and the IP address sent by the second electronic device 200, the first wireless network card 130 uses the first letter key to set the service setting identification. The code, and the second letter key to set the above IP address. According to the above embodiment of the present invention, the second electronic device 200 includes a second wireless network card 230. When the second wireless network card 230 scans to the service setting identifier and IP address sent by the first electronic device 100, the first wireless device can When the network card is connected, the first wireless network card 130 generates a key and sends the key to the second wireless network card 230. Then, the first wireless network card 130 first interrupts the connection with the second wireless network card 230, and uses the key encryption. An electronic device 100 re-broadcasts the set service setting identification code. When the second wireless network card 230 scans the set service setting identification code again, the second wireless network card 230 is received by the first wireless network card 130. The key and the first wireless network card 130 complete the connection.
