Description

Technical Field

[0001] The present invention relates to the field of data communication, and in particular to a dumb terminal detection method, system, storage medium and electronic equipment. Background Art

[0002] In a wireless LAN environment, in order to prevent a large number of ARP (Address Resolution Protocol) broadcast messages from being forwarded to the wireless environment and affecting the air interface environment, the ARP proxy function is used on the AP (Access Point) to intercept a large number of ARP request broadcast messages and reply to ARP response messages on behalf of the wireless terminal. The main function of ARP proxy is to reduce air interface messages and achieve the effect of optimizing the air interface environment. The strategy adopted in the implementation of this function is generally to intercept all ARP broadcast messages that do not request wireless terminal information. This strategy requires the AP to have the corresponding information of the IP addresses and MAC addresses of all associated wireless terminals. If it does not have the corresponding information, it is very likely that other devices will not be able to discover the device through ARP requests.

[0003] Furthermore, since the AP needs the correspondence between the terminal's IP address and MAC address when replying to the ARP response on behalf of the terminal, if there is a wireless dumb terminal in the environment (such as a printer, scanner, projector, etc.), the wireless dumb terminal will no longer send any messages to the outside after self-association, and the AP will not be able to obtain the IP address of the wireless dumb terminal, resulting in the lack of wireless dumb terminal information in the network environment, and then other devices in the environment cannot automatically discover the wireless dumb terminal through ARP requests.

[0004] At present, the common processing method for wireless dumb terminals in wireless LAN is that the AP sends a disassociation frame to let the wireless dumb terminal leave the current network environment. Whether this processing method is effective depends entirely on whether the wireless dumb terminal will perform a different packet sending behavior after re-association than the first association. It is relatively passive and affects the terminal access experience to a certain extent.

[0005] Therefore, the current common way to handle wireless dumb terminals will only cause information loss of some terminals at most when the ARP proxy function is not enabled. However, when the ARP proxy function is enabled, other devices on the same network may not be able to connect to the wireless dumb terminal. How to ensure normal communication between wireless dumb terminals and other devices while enabling the ARP proxy function has become an urgent problem to be solved. Summary of the invention

[0006] The purpose of the present invention is to overcome the problems existing in the prior art and provide a dumb terminal detection method, system, storage medium and electronic device to ensure normal communication between a wireless dumb terminal and other devices under the premise of enabling an ARP proxy answering function.

[0046] The technical solution of the present invention is clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all of the embodiments. The components of the embodiments of the present application described and shown in the accompanying drawings can be arranged and designed in various configurations. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0047] It should be noted that the defects existing in the solutions in the above-mentioned prior art are the results obtained by the inventor after practice and careful research. Therefore, the discovery process of the above-mentioned problems and the solutions proposed in the embodiments of the present application for the above-mentioned problems below should all be the contributions made by the inventor to the present application in the process of invention and creation, and should not be understood as technical contents known to technical personnel in this field.

[0048] Reference Figure 1 The application scenario of the present invention is mainly composed of AP, normal terminal, dumb terminal, uplink device and DHCP server in the uplink environment. Figure 2 As shown, in the current wireless LAN environment, there are two wireless terminals on the AP, and the DHCP server is connected to the uplink device to allocate IP addresses to the connected wireless terminals. After ARP proxy is enabled in the current network, the ARP request sent from the uplink device to the wireless terminal is replied by the AP, and the ARP request is no longer forwarded to the wireless side, which reduces a large number of ARP broadcast messages from the uplink environment and optimizes the air interface environment. The wireless environment of the embodiments of the present invention is all the case where ARP proxy is enabled.

[0049] In view of the technical problems pointed out in the background technology, the embodiments provided by the present invention are as follows:

[0050] Example 1

[0051] Reference Figure 3 In an exemplary embodiment, a dumb terminal detection method is provided, comprising the following steps:

[0052] S1. The AP turns on ARP proxy reply. When a normal terminal is connected, the network segment address of the current network is obtained. After confirming that a dumb terminal is connected to the AP, step S2 is executed.

[0053] S2. The AP uses the IP addresses in the network segment address of the current network and the MAC address of the dumb terminal association frame to assemble a free ARP message, and sends the free ARP message to the dumb terminal for detection;

[0054] S3. When the IP address in the gratuitous ARP message received by the dumb terminal is the same as its own IP address, the dumb terminal replies with an ARP reply message for the gratuitous ARP message;

[0055] S4. The AP obtains the IP address of the dumb terminal according to the ARP reply message sent by the dumb terminal.

[0056] Specifically, in step S1, in a wireless networking environment, ARP proxy is enabled. When the AP is normally connected to a normal terminal, the DHCP message of the normal terminal when associated is captured to obtain the network segment address of the current network environment. If the terminal does not obtain the address through the DHCP message, the network segment address is composed according to the IP address of the normal terminal and the common network mask (such as 28, 24, 16, etc.). After the wireless terminal is associated, the AP obtains the MAC address of the wireless terminal through the association frame. If the AP cannot obtain the IP address of the terminal for a long time after obtaining the MAC address, it can be confirmed that the terminal is a dumb terminal.

[0057] In step S2, the IP addresses in the network segment address of the current network that have been acquired by other terminals are excluded, and the IP addresses in the current network are used in combination with the MAC addresses in the associated frames in the set order to assemble a free ARP message, which is sent by the AP to the dumb terminal.

[0058] In step S3, after the dumb terminal receives a free ARP message with the same IP address as itself, it replies through an ARP reply message, and the AP obtains the corresponding relationship between the IP address and the MAC address of the dumb terminal according to the sender ip and sendermac fields of the reply. The present invention can solve the defect that the wireless dumb terminal cannot be discovered by other devices in a wireless networking environment using the ARP proxy answering function, and at the same time, in a conventional wireless networking environment, it can collect information for the dumb terminal and improve the information of the current network.

[0059] Example 2

[0060] Based on the inventive concept of embodiment 1, this embodiment provides specific examples, such as Figure 4 As shown in the figure, when a normal terminal accesses the AP, the network segment address of the current network environment is parsed according to the DHCPACK message sent by the DHCP server to the terminal. The DHCPACK message contains the your ip address field to record the terminal IP address (192.168.1.128), and the option subnetmask field to record the mask (255.255.255.0). The two data are combined to obtain the network segment address of the current network (192.168.1.0 / 24).

[0061] When an AP accesses a dumb terminal (the terminal address is a static address not obtained through the DHCP protocol), the AP first parses the associated frame of the terminal, obtains the terminal's MAC address, and saves it. It is impossible to confirm whether the terminal is a dumb terminal at the first time of terminal access. The AP needs to obtain the terminal's IP address and MAC based on the ARP message entering the wireless interface and the DHCPACK message going out of the wireless interface (the ARP message entering the wireless interface must be sent by the wireless terminal, and the DHCPACK message going out of the wireless interface must be replied to the wireless terminal), and save it in a terminal IP address and MAC address correspondence table. If after a period of time, there is only a MAC address in a table item of the correspondence table, it can be confirmed that the IP address of the terminal corresponding to the MAC address has not been obtained, and the terminal corresponding to the MAC address is a dumb terminal.

[0062] After confirming that the terminal is a dumb terminal, the AP can use the previously calculated network segment address (192.168.1.0 / 24) of the current network one by one in the order from small to large (or from large to small) to combine with the MAC address of the dumb terminal stored on the AP to assemble a free ARP message and send it to the dumb terminal, assembling a free ARP message for each IP address. Specifically, in the current embodiment, you can start trying from 192.168.1.2, and assemble a free ARP message in combination with the dumb terminal MAC address 222.222.222. The destination MAC field of the free ARP message can be directly filled in with the dumb terminal MAC 222.222.222 to avoid broadcasting ARP messages affecting the air interface environment. In the process of assembling and sending ARP messages in sequence using IP addresses from 192.168.1.2 to 192.168.1.254, the AP can skip some addresses according to the recorded current terminal IP. For example, when the IP address of a terminal in the environment is 192.168.1.128, the address can be directly skipped when assembling the free ARP message. It is easy for people in this field to understand that assembling the free ARP message using the IP addresses in the network segment of the current network one by one in the set order does not mean that all IP addresses in the network segment of the current network must be used, because as long as the ARP reply message replied by the dumb terminal is received, the remaining IP addresses do not need to be tried.

[0063] Furthermore, if the normal terminal does not use the DHCP protocol to obtain an address after access, but a statically configured address, then after the AP obtains its IP address through the ARP message of the normal terminal, it can directly use a common network mask (such as 28, 24, 16, etc.) to form a network segment address.

[0064] Furthermore, when the target IP of the free ARP message sent by the AP is consistent with the IP address of the dumb terminal, the dumb terminal will reply to the free ARP message with an ARP reply message according to the ARP protocol. The AP can capture the ARP reply message and parse out the IP address, MAC address and the correspondence between the IP address and MAC address of the dumb terminal.

[0068] When a dumb terminal is confirmed to have accessed, a free ARP message is assembled one by one using the IP addresses in the network segment address of the current network in combination with the MAC address of the dumb terminal associated frame, and the free ARP message is sent to the dumb terminal;

[0069] Obtain the IP address of the dumb terminal based on the ARP reply message sent by the dumb terminal.
