Description

A communication method and device for wireless router

Technical Field

The present invention belongs to the field of communications, and in particular, relates to a communication method and device for a wireless router.

Background Art

A router is the hub of the Internet and a device that connects local area networks and wide area networks. It automatically selects and sets routes based on the channel conditions, and sends data in the best order along the best path. Routers work at the third layer of the OSI model and provide two important mechanisms: routing and forwarding. Routing: The work of the router control layer, which determines the routing path that the data packet takes from the source to the destination. Forwarding: The work of the router data layer, which transfers the data packet at the router input to the appropriate router output (performed inside the router). A wireless router is a router with wireless coverage function used for users to access the Internet. A wireless router can forward broadband network signals to nearby workstations (stations) through antennas. Workstations are, for example, laptops, mobile phones that support wifi, etc., to enable wireless Internet access at the workstations. At present, the connection security of wireless routers needs to be further improved.

DETAILED DESCRIPTION

The present application is further described below in conjunction with the accompanying drawings and embodiments.

In the following introduction, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance. The following introduction provides multiple embodiments of the present invention, and different embodiments can be replaced or combined, so this application can also be considered to include all possible combinations of the same and/or different embodiments recorded. Therefore, if one embodiment includes features A, B, and C, and another embodiment includes features B and D, then this application should also be considered to include embodiments containing one or more of all other possible combinations of features A, B, C, and D, even though the embodiment may not be clearly recorded in the following text.

As shown in FIG. 1 , the communication method of the wireless router of the present application includes: S101, the wireless router receives a first connection request sent by a terminal to be verified; S103, the wireless router determines whether the terminal to be verified is a terminal that meets a first preset condition based on the first connection request; S105, if the terminal to be verified is a terminal that meets the first preset condition, the wireless router generates a permission code, and determines whether to establish a connection with the terminal to be verified based on the permission code.

During the wireless connection process, the workstation must go through an identification process before joining any network. The process of identifying existing networks in the area is called scanning. Scanning is divided into two types: active scanning and passive scanning. Among them, active scanning: the workstation plays a more active role. The workstation actively tries to find a wireless network. The workstation will send a Probe Request frame on each channel to request a specific network to respond. Passive scanning: Passive scanning can save battery power because no signal needs to be transmitted. In passive scanning, the workstation will continuously switch between the channels listed in the channel list and wait for the arrival of beacon frames. Any frames received will be temporarily stored. Beacons are designed to let workstations know the parameters required to join a basic service set in order to communicate.

The working principle of a wireless router is as follows: Receive Internet data from the modem of the Internet Service Provider (ISP). Convert the received signal into a digital signal and then transfer it from the WAN port to the Local Area Network (LAN) port. Transcode the data packet from the wireless interface into a wireless signal through the LAN port and send it to the connected terminal device on the device. Receive the data sent by the terminal device, convert it into a data packet and send it to the Internet.

The working mechanism of a wireless router includes: Signal reception and transmission: Wireless routers communicate with devices through wireless signals, which can be transmitted by radio waves. Access control: Wireless routers can authenticate devices that request access to data packets through access control lists, and then authorize access. NAT (Network Address Translation) conversion: A widely used network security technology that can associate an external public IP address with multiple private IP addresses in the network behind the router. DHCP (Dynamic Host Configuration Protocol) configuration: It is a network protocol, short for "Dynamic Host Configuration Protocol". It can automatically configure network information for terminal devices by dynamically assigning information such as IP addresses, subnet masks, DNS servers, etc. Wireless security: Wireless routers can protect the security and confidentiality of data through built-in encryption mechanisms such as WiFi Protected Access II (WPA2).

The communication between the router and the mobile phone, for example, includes the following steps: Mobile phone connects to the router: The mobile phone connects to the router via Wi-Fi. IP address allocation: When the mobile phone is connected to the router, the router will assign an IP address to the mobile phone for communication within the local area network. Network data transmission: When the mobile phone needs to communicate with other devices on the Internet, it will send data to the router. The router will forward the data packet to the corresponding gateway device based on the target IP address. Gateway device: The gateway device can be a modem connected to the router or a router of an ISP (Internet service provider). After the gateway device receives the data packet, it will forward it to the target device on the Internet. Target device response: When the target device receives the data packet, it will return the response data packet to the gateway device. Router processing: The gateway device forwards the response data packet to the router. The router will forward the response data packet back to the network interface connected to the mobile phone based on the source IP address. Mobile phone reception: The mobile phone receives the response data packet, parses the data packet according to the protocol, and displays the response result to the user.

In the present application, in step S103, the first connection request includes the MAC address of the terminal to be verified and the password sent by it; the first preset condition includes whether the terminal to be verified is connected for the first time and whether it is a disabled device. If it is the first connection, step S105 is executed; if it is not the first connection, check whether it was connected normally before. If it was connected normally before, the wireless router establishes a connection with the terminal to be verified; if it is a disabled device, the connection with the terminal to be verified is refused.

In the present application, in step S105, if the terminal to be verified is a terminal that meets the first preset condition, the wireless router generates a permission code and sends the permission code to the management terminal, which is the terminal that has been connected to the wireless router for the longest time or the terminal that establishes a connection with the wireless router the earliest or a preset terminal. A terminal can be designated as a management terminal when the wireless router is enabled, or a terminal can be designated as a management terminal during the use of the wireless router. The wireless router generates a permission code and sends the permission code to the management terminal, and the user of the management terminal sends the permission code to the user of the terminal to be verified. The terminal to be verified receives the permission code entered by the user and sends the permission code to the wireless router. The wireless router checks whether the permission code is correct. If it is correct, a connection is established with the terminal to be verified. If it is incorrect, the connection is refused to be established with the terminal to be verified.

In the present application, the first connection request, for example, also includes biometric information of the terminal user to be verified, such as fingerprint, iris, etc.

In the present application, the wireless router determines whether the terminal to be verified is a terminal that meets the first preset condition based on the first connection request; if the terminal to be verified is a terminal that meets the first preset condition, the wireless router generates a permission code and determines whether to establish a connection with the terminal to be verified based on the permission code, thereby preventing unauthorized terminals from connecting to the router, thereby increasing the security of wireless router communications.

As shown in FIG. 2 , the communication device of the wireless router of the present application includes: a receiving unit 201, which is used to receive a first connection request sent by a terminal to be verified; a determining unit 202, which is used to determine whether the terminal to be verified is a terminal that meets a first preset condition according to the first connection request; a connecting unit 203, which is used for the wireless router to generate a permission code if the terminal to be verified is a terminal that meets the first preset condition, and determine whether to establish a connection with the terminal to be verified according to the permission code.

The first connection request includes the MAC address of the terminal to be verified, the sent password and/or the user's biometric information; the first preset condition includes whether the terminal to be verified is connected for the first time and whether it is a disabled device.

Among them, the connection unit is used to: if the terminal to be verified is a terminal that meets the first preset condition, generate a permission code, and send the permission code to the management terminal, the management terminal is the terminal with the longest connection time with the wireless router or the terminal that establishes a connection with the wireless router earliest or a preset terminal; check whether the permission code sent by the terminal to be verified is correct, if it is correct, establish a connection with the terminal to be verified, if it is not correct, refuse to establish a connection with the terminal to be verified.

The terminal to be verified is a tablet computer, mobile phone, wearable device or laptop computer.
