[0003] For dual-SIM dual-standby multi-mode routers, the commonly used internet access modes are mainly divided into primary backup mode and load balancing mode. Primary backup mode only uses the primary SIM network, and only uses the secondary SIM network when the primary SIM network fails; while load balancing mode uses both SIM networks simultaneously to provide an internet access environment.

[0004] Neither of the above two modes can achieve primary and secondary SIM card network switching based on different subnet conditions; moreover, the traditional multi-SIM card network handles different network priorities in a relatively simple and mechanical way, often only detecting network connectivity as the basis for switching.

[0035] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0036] It should be noted that the following detailed description is illustrative and intended to provide further explanation of the invention. Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains.

[0037] Example 1

[0038] This embodiment provides a multi-mode router network switching method based on subnet device characteristics. It switches between primary and secondary SIM card networks according to different subnet device environments, achieving the effect of switching between primary and secondary SIM cards for internet access based on different subnet environments.

[0039] This embodiment provides a multi-mode router network handover method based on subnet device characteristics, which handles multi-mode router network handover according to the subnet device situation, such as... Figure 1 As shown, it includes the following steps:

[0040] Step 1: Obtain statistical information of the router's primary and secondary SIM card networks, and classify the two networks into two standard network categories.

[0041] The statistical information includes: SIM card number, phone number, signal strength, base station information, network standard, operator information, remaining data on the card, upload and download speeds, packet loss rate, and latency information.

[0042] First, use the router's built-in tools to collect information about the router itself, such as the network type, signal quality, carrier information, and remaining data on each SIM card. Then, use the router's built-in tools to test the upload and download speeds, packet loss rate, and latency of each SIM card. Based on the collected information, classify the primary and secondary SIM cards into two standard network categories, such as: premium network and ordinary network, low-latency network and high-latency network, high-bandwidth network and low-bandwidth network, China Telecom network and China Unicom network, etc.

[0043] Specifically, when the router's primary SIM card is connected to China Mobile and the secondary SIM card to China Telecom, the router waits for both network cards to successfully connect to the network after startup. It then reads the SIM card information to obtain the card numbers, phone numbers, and other information of both SIM cards. Next, based on signaling interactions with the base station, it obtains information such as the signal strength, base station information, and network standard. Then, it sends SMS messages to the operator to obtain the SIM card's data plan information and data usage. Finally, it uses speed test tools such as Speedtest to test the network speed, bandwidth, latency, and packet loss of each network. Finally, based on the obtained information, it categorizes the two networks, such as: premium networks and ordinary networks, low-latency networks and high-latency networks, high-bandwidth networks and low-bandwidth networks, China Telecom networks and China Mobile networks, etc.

[0044] Step 2: Read the network switching rules configured by the user on the router, and divide the dual-SIM network into network 1 and network 2 according to the rules set by the user.

[0045] Specifically, it reads the router's user configuration, creates preset conditions, and sets the user to always use China Telecom internet when an Android device connects.

[0046] Step 3: The router monitors subnet devices connected to it through hardware PHY registers, WIFI links, ARP packets, and DHCP requests. When a subnet device connects to the router, the router uses NMAP active probing and BPF packet capture analysis to detect the connected subnet device and obtain necessary information, such as the subnet device's MAC address, IP address, operating system, and currently open ports. The router also periodically analyzes the subnet device's traffic consumption over a period of time and collects information about the external servers connected to the devices. Figure 2 The image shows DHCP requests and ARP packets captured by packet capture. Figure 3 It is an ARP packet format. Figure 4 It is in DHCP packet format. Based on the request packet, you can obtain information such as the MAC address of the newly connected sub-device and the IP address obtained by DHCP. Figure 5 This information is obtained by the NMAP tool. After obtaining the IP address, you can use the NMAP detection tool to obtain information such as the sub-device's operating system, open ports, and services. Figure 6 The image shows the router's ARP table. Based on the ARP table, information such as the HW type, Flags, and access interface of the corresponding MAC address can be obtained.

[0047] Step 4: Configure the network type of the subnet device according to the system information data, and configure the ownership type of the subnet device according to the traffic consumption and the connected external network server information.

[0048] Specifically, based on the collected system information data such as MAC address, IP address, sub-device operating system, and sub-device port, a "device profile" is generated within the router. First, the device is categorized and configured with different network types according to the user-configured network type, such as: Network Device 1, Network Device 2, Uncategorized Network Device. Then, based on the device's characteristics, it is further categorized and configured with its class, such as: High-traffic device, Low-latency device, Network-insensitive device, Telecom network device, China Unicom network device, etc. Figure 7 As shown.

[0049] Step 5: Based on the network type and ownership type of the subnet devices, and in conjunction with the network division, switch the router's network: Sort the devices according to the user-defined rules and the router's built-in rules, assign priority to each subnet device, and then, based on the network type and ownership type of the access devices, and in conjunction with the number of devices under each priority, switch the router network to the corresponding standard network while meeting the needs of most devices, thus achieving the purpose of switching the primary and secondary SIM card networks according to the subnet device status.

[0050] Specifically, the router waits for device access. When a Windows PC connects to the subnet and obtains an IP address using the DHCP protocol, the PC sends a DHCP request to the router. Upon receiving the DHCP request, the router records the PC's hostname and MAC address as device identifiers. Then, it assigns an IP address to the device according to the DHCP protocol and records it in the router's database. Next, it uses an NMAP tool to detect the PC's operating system, open ports, and other information, recording this data in the database. Finally, it checks the PC's device information to see if it meets the user's network switching requirements. If the device's operating system is Windows and it's not an Android user, no switching operation is needed.

[0051] Using BPF packet capture analysis, the PC device's traffic data usage was analyzed over a period of time. It was detected that the server address accessed by the device in large quantities belonged to the mobile public network segment, with small data transmission volume and mainly UDP data. The PC device was marked as a mobile low-traffic device and recorded in the database. When the subnet device is idle, the network can be actively switched to the mobile network.

[0052] If another network camera with a static IP address is subsequently connected, the router will use the ARP table and BPF packet capture to obtain the device's MAC address, hostname, and IP address. It will then record this information in its database and use NMAP to further probe the device. Based on the packet capture information, the router analyzes the device's transmitted video stream data. If the upload traffic is high, the device is marked as a high-bandwidth device. Considering the data traffic usage of the PC and the camera, the router determines that a network capable of handling high upload traffic should be used. The results are recorded in the router's database, and when the time is right, the router will switch the network to a high-bandwidth, high-speed telecommunications network.

[0053] Subsequently, an Android phone connected to the subnet via Wi-Fi. Following the detection steps outlined above, the router created a database entry for the phone user and updated the database. Since the Android system was detected, meeting the user's configured switching conditions, the network was fixed to the telecommunications network. The network switching procedure switched to logging mode, only recording the current network status and no longer actively switching networks. Only when the Android device disconnects from the Wi-Fi connection will the network switching procedure switch back to control mode, monitoring the network status and switching networks as needed. The network topology at this point is as follows: Figure 8 .

[0054] Step 6: Set a time interval to repeatedly execute the above steps, and dynamically switch the device's standard network type according to the current network conditions.

[0055] The multi-mode router network switching method based on subnet device characteristics provided in this embodiment can switch between primary and secondary networks according to different subnet environments. Traditional multi-NIC networks handle different network priorities in a relatively simple and mechanical way, often only detecting network connectivity as the basis for switching. This invention can collect information about subnet devices and the router's own network status, and use this as the basis for network switching. Thus, it can select the appropriate network mode according to different subnet states and the router's own network status, achieving automatic network switching.

[0056] The multi-mode router network switching method based on subnet device characteristics provided in this embodiment can be configured with different network switching conditions to achieve fine-grained control over network switching. The router can provide a configuration page for users, who can configure the network switching conditions for subnet devices according to their own needs. For example, when a mobile device is present in the subnet, the router can be configured to switch to a high-bandwidth network. When the router detects that the operating system of the subnet device is a mobile phone system, it will automatically switch to the high-bandwidth network card for internet access.

[0057] The multi-mode router network switching method based on subnet device characteristics provided in this embodiment can automatically learn according to the set switching conditions to achieve intelligent network switching. The router will periodically record the different network interfaces corresponding to each subnet device. When the subnet device connects again, it will automatically switch to the frequently used network interface based on the past network records.

[0058] The multi-mode router network switching method based on subnet device characteristics provided in this embodiment is key in that the router can automatically handle the switching of primary and secondary SIM cards based on the subnet device status and the router's own network status. The router can periodically acquire subnet device information and its own information, and can capture data packets from subnet devices over a period of time to analyze their internet access behavior, using this as a basis for switching between primary and secondary SIM cards. The router has automatic learning capabilities; it can record suitable SIM cards and network modes for devices based on their internet access behavior over a period of time. When the device reconnects, it can automatically switch to the appropriate SIM card network based on past records.
