[0001] The present invention relates to a routing device, in particular to a routing device for a terminal device to access a network device, and a network connection method using the above routing device. Background Art

[0002] The network device has an internal web server, which can be accessed through a browser of a terminal device such as a laptop, a mobile phone, or a tablet computer. To access the web server of the network device with a fixed Internet Protocol address (i.e., IP address) through a wireless network, a wireless routing device must be used to connect to the network device with an RJ45 interface through a network cable. Before this, according to the Transmission Control Protocol / Internet Protocol (i.e., TCP / IP protocol), the user must manually configure the network device or the wireless routing device data transmission to ensure that the terminal device can access the web server of the network through WI-FI. When manually configuring, the user must first obtain parameters such as the Internet Protocol address of the network device through some specified tools that some users may not be able to use or are difficult for users to operate, and adjust the Internet Protocol address of the wireless routing device so that it is in the same network segment as the Internet Protocol address of the network device. Otherwise, due to the limitations of the Transmission Control Protocol / Internet Protocol data transmission, the terminal device will not be able to access the network device. This brings inconvenience to ordinary users to access the network device through the terminal device. Summary of the Invention

[0003] An object of the present invention is to provide a routing device for a terminal device to access a network device, which can automatically configure network parameters and facilitate the user to establish a connection between the terminal device and the network device.

The first communication module can send the first response message to the processing module. The processing module can modify the Internet Protocol address of the routing device according to the first response message so that the Internet Protocol address of the routing device is in the same network segment as the Internet Protocol address of the network device. The first response message includes the Internet Protocol address of the network device. The second communication module is signal-connected to the processing module and is used for signal connection with the terminal device. The processing module can allocate the Internet Protocol address in the same network segment as the Internet Protocol address of the routing device to the terminal device through the second communication module.

[0040] In order to have a clearer understanding of the technical features, objectives, and effects of the invention, the specific embodiments of the invention are now described with reference to the accompanying drawings. In the figures, the same reference numerals denote components having the same or similar structures but the same functions.

[0041] In this document, "illustrative" means "serving as an example, instance, or illustration", and any illustration or embodiment described as "illustrative" in this document should not be construed as a more preferred or advantageous technical solution.

[0042] A routing device is a hardware device that connects two or more networks. It acts as a gateway between networks and is a dedicated intelligent network device that reads the address in each data packet and then decides how to transmit. The role of a routing device is to connect different networks and select the line for information transmission. Selecting a smooth and fast short route can improve communication speed and network system throughput, reduce the communication load of the network system, save network system resources, and thus enable the network system to exert greater benefits.

[0043] Figure 1 It is a schematic structural diagram for illustrating a schematic implementation manner of a routing device. As Figure 1 shown, the routing device 100 includes a first communication module 10, a processing module 20, and a second communication module 30.

The first probe message and the first response message are discovery configuration protocol messages. The first response message includes the Internet Protocol address of the network device 80, the subnet mask of the network device 80, and the gateway of the network device 80.

[0045] The processing module 20 is signal-connected to the first communication module 10.

The processing module 20 respectively defines the domain names of the network device 80 and the routing device 90, and respectively sends out the correspondence between the Internet protocol address of the network device 80 and the domain name of the network device 80, and the correspondence between the Internet protocol address of the routing device 100 and the domain name of the routing device 100. The terminal device 90 can generate a web access request message including the Internet protocol address of the web server to be accessed by parsing the domain name data of the web server to be accessed according to the received correspondence between the Internet protocol address and the domain name, and send the web access request message to the processing module 20 through the second communication module 30. The processing module 20 can determine that the Internet protocol address of the web server to be accessed is the Internet protocol address of the network device 80 or the Internet protocol address of the routing device 100 according to the Internet protocol address of the web server to be accessed in the web access request message. If the judgment result is the Internet protocol address of the network device 80, the processing module 20 forwards the web access request message to the first web server 81 through the first communication module 10. The first web server 81 can generate a second response message after parsing the web access request message and send it to the processing module 20 through the first communication module. The processing module 20 can send the second response message to the terminal device 90 through the second communication module 30.

The browser of the terminal device displays the access result. The second web server is used to configure the WI-FI name, WI-FI password, communication status, and channel selection and switching of the routing device, and is used to view the Internet protocol address and communication status of the connected network device. Thus, the user can set the parameters of the routing device.
