Description

Technical Field

[0001] This invention relates to the field of communications, and more specifically, to a method and apparatus for configuring a subnet mask, a storage medium, and an electronic device. Background Technology

[0002] In related technologies, due to the rapid development of the Internet of Things (IoT), network environments have become increasingly complex and variable, especially in the increasingly widespread application of private network environments. A private network is a network built to meet the needs of IoT development, including abundant number resources, the "scale, mobility, and security" characteristics of IoT, personalized business requirements, and high-quality network assurance for customers. IoT users use dedicated numbers. In a private network environment, because IP addresses are fixed and often bound to SIM cards, when different devices obtain IP addresses that are close together, communication failures may occur between different devices due to an unreasonable subnet mask design.

[0003] In related technologies, after a module initiates a PDN (Packet Data Network) dial-up connection, its WAN (Wide Area Network) port obtains the corresponding IP address, subnet mask, and gateway address from the base station. According to current subnet mask and gateway calculation rules, there is a possibility of data communication failure between two devices in a private network environment. When device 1's IP address is 192.168.200.72 and device 2's IP address is 172.168.200.73, since 192.168.200.72 is a network address, not a host address, for 192.168.200.73, the received data packet will not be forwarded to the upper-layer application, resulting in a ping failure. Furthermore, because customers in a private network environment need to connect multiple module devices to the same host computer, each module has its own network card. Due to IP address conflicts, some module network cards on the host computer may fail to obtain IP addresses.

[0004] No efficient and accurate solution has yet been found to address the aforementioned issues in the relevant technologies. Summary of the Invention

[0030] Example 1

[0031] The method embodiment provided in Embodiment 1 of this application can be executed in a communication module, computer, smart car, smartwatch, shared bicycle, smart cabinet, or similar computing device. Taking its operation on a communication module as an example, Figure 1 This is a hardware structure block diagram of a communication module according to an embodiment of the present invention. Figure 1 As shown, the communication module may include one or more ( Figure 1Only one is shown in the diagram. A processor 102 (which may include, but is not limited to, a microprocessor MCU or a programmable logic device FPGA, etc.) and a memory 104 for storing data are also shown. Optionally, the communication module may further include a transmission device 106 for communication functions and an input / output device 108. Those skilled in the art will understand that... Figure 1 The structure shown is for illustrative purposes only and does not limit the structure of the communication module described above. For example, the communication module may also include components that are more... Figure 1 The more or fewer components shown, or having the same Figure 1 The different configurations shown.

[0032] The memory 104 can be used to store communication module programs, such as application software programs and modules, like the communication module program corresponding to a subnet mask configuration method in this embodiment of the invention. The processor 102 executes various functional applications and data processing by running the communication module program stored in the memory 104, thereby implementing the above-described method. The memory 104 may include high-speed random access memory and may also include non-volatile memory, such as one or more magnetic storage devices, flash memory, or other non-volatile solid-state memory. In some instances, the memory 104 may further include memory remotely located relative to the processor 102, and these remote memories can be connected to the communication module via a network. Examples of such networks include, but are not limited to, the Internet, corporate intranets, local area networks, mobile communication networks, and combinations thereof.

[0033] The transmission device 106 is used to receive or send data via a network. Specific examples of the network described above may include a wireless network provided by the communication module's communication provider. In one example, the transmission device 106 includes a Network Interface Controller (NIC), which can connect to other network devices via a base station to communicate with the Internet. In another example, the transmission device 106 may be a Radio Frequency (RF) module used for wireless communication with the Internet.

[0034] This embodiment provides a method for configuring a subnet mask. Figure 2 This is a flowchart of a subnet mask configuration method according to an embodiment of the present invention, such as... Figure 2 As shown, the process includes the following steps:

[0035] Step S202: Send a Packet Data Network (PDN) dialing request to the network end;

[0036] In this embodiment, the PDN (Packet Data Network) dialing request is the trigger request for the dialing process, which refers to the process of a mobile device connecting to the Internet through a wireless network. The PDN dialing process includes:

[0037] When a user turns on the Mobile Data Network (MDN) switch, the phone sends a request to the network to connect to the internet.

[0038] After receiving the request, the network sends an APN (Access Point Name) configuration file to the mobile phone. An APN is the name of a network access point used to identify the network type and service provider. Upon receiving the APN configuration file, the communication module establishes a connection with the network based on the information in the file. The communication module then sends a PDP (Packet Data Protocol) request to the network. PDP is a protocol used to transmit data packets in mobile networks. Upon receiving the PDP request, the network assigns an IP address to the mobile phone. An IP address is a unique identifier used to identify the device on the internet. After receiving the IP address, the communication module configures network parameters such as the subnet mask and can then access the internet.

[0039] Step S204: After PDN activation is successful, parse the mask configuration mode of the target communication module, wherein the mask configuration mode is used to indicate the method of obtaining the WAN port mask of the target communication module.

[0040] Step S206: Configure the subnet mask of the target communication module according to the mask configuration mode.

[0041] Through the above steps, a Packet Data Network (PDN) dial-up request is sent to the network. After successful PDN activation, the mask configuration mode of the target communication module is parsed. The mask configuration mode indicates how to obtain the WAN port mask of the target communication module. The subnet mask of the target communication module is configured according to the mask configuration mode. After successful PDN activation, the subnet mask can be dynamically configured according to the mask configuration mode, which solves the technical problem of the single subnet mask configuration method in related technologies. Different subnet mask configuration methods are available for users to choose from, ensuring that data services can be performed normally after dialing in different network environments. It solves the problems of ping failures between different settings in private network environments and the inability to obtain IP addresses for multiple modules of the same device, thus improving the compatibility of the communication module in different network environments.

[0042] In this embodiment, before parsing the mask configuration mode of the target communication module, the following steps are also included:

[0043] S11, the host computer of the target communication module detects the user configuration request;

[0044] Users input a configuration request on the host computer based on the network environment and actual needs, triggering the configuration process.

[0045] S12, respond to the user configuration request and generate a mask configuration instruction for the target communication module based on the user configuration request;

[0046] S13, use the mask configuration instruction to configure the mask configuration mode of the target communication module.

[0047] Optionally, configuring the target communication module's mask configuration mode using mask configuration instructions includes: locating the nv configuration file in the target communication module's configuration information; and configuring the dhcp_subnetmask_calc parameter of the nv configuration file using mask configuration instructions to configure the target communication module's mask configuration mode.

[0048] Optionally, the mask configuration command is GTNETMASK, and the path to dhcp_subnetmask_calc is modem / nv / item_files / modem / data / protocols / dhcp_subnetmask_calc. dhcp_subnetmask_calc is a parameter used to calculate the DHCP subnet mask. DHCP (Dynamic Host Configuration Protocol) is a network protocol used to automatically assign IP addresses and other network configuration information to devices. In DHCP, the subnet mask is used to determine the number of hosts and subnets in the network. The dhcp_subnetmask_calc parameter is used to calculate the subnet mask that the DHCP server should assign to the client. In this embodiment, the following parameters are required:

[0049] IP address: The IP address of the DHCP server;

[0050] Subnet mask bit width: Used to specify the number of bits in the subnet mask, for example, 24 bits represents 255.255.255.0;

[0051] Number of subnets: Specifies the number of subnets in the network;

[0052] Mask configuration mode: Used to indicate the method for obtaining the WAN port mask of the target communication module;

[0053] Using the parameters mentioned above, dhcp_subnetmask_calc can calculate the correct subnet mask to ensure that all devices in the network can communicate correctly.

[0054] This embodiment develops AT+GTNETMASK to configure the WAN subnet mask. By configuring the modem / nv / item_files / modem / data / protocols / dhcp_subnetmask_calc parameter, the function of dynamically allocating the WAN subnet mask after dialing is realized.

[0055] In one embodiment of this example, parsing the mask configuration pattern of the target communication module includes: reading the mask configuration parameters of the target communication module; reading the field value of a specified field in the mask configuration parameters; and searching for a mask configuration pattern that matches the field value in a preset mapping table.

[0056] In one example, the communication module sends an AT to configure the WAN subnet mask. If AT+GTNETMASK = 1, it is calculated based on the IP address; if AT+GTNETMASK = 2, it is calculated based on the IP address classification; if AT+GTNETMASK = 3, "255.255.255.0", the fixed WAN subnet mask is 255.255.255.0.

[0057] Optionally, searching for a mask configuration pattern matching the field value in the preset mapping table includes: if the field value is a first field value, searching for a first mask configuration pattern matching the first field value in the preset mapping table, wherein the first mask configuration pattern is used to indicate that the subnet mask is calculated based on the IP address; if the field value is a second field value, searching for a second mask configuration pattern matching the second field value in the preset mapping table, wherein the second mask configuration pattern is used to indicate that the subnet mask is calculated based on the class of the IP address; if the field value is a third field value, searching for a third mask configuration pattern matching the third field value in the preset mapping table, wherein the third mask configuration pattern is used to indicate that a static mask address is used.

[0058] In this embodiment, configuring the subnet mask of the target communication module according to the mask configuration mode includes: obtaining the IP address of the target communication module; creating a dnsmasq process within the target communication module; and using the dnsmasq process to configure the subnet mask of the target communication module's Dynamic Host Configuration Protocol (DHCP) based on the mask configuration mode and the IP address.

[0059] The module internally configures the DHCP subnet mask with the appropriate subnet mask by using dnsmasq, thereby preventing the host computer from being unable to obtain an IP address when there are multiple modules.

[0060] In one example, the module's WAN port obtains the corresponding IP address, subnet mask, and gateway address from the base station. The gateway address is calculated as follows: if the address obtained by adding 1 to the IP address is the broadcast address of that subnet, then the IP address minus 1 is used as the gateway address; otherwise, the IP address plus 1 is used. The subnet mask is calculated by setting all leading 1s and all trailing 0s to the positions where changes occur in the binary representation of the IP address. An example is shown below:

[0061] IP=192.168.200.72(1100 0000 1010 1000 1100 1000 0100 1000)

[0062] netmask=255.255.255.240(1111 11111111 1111 1111 111111110000)

[0063] gwip=192.168.200.73(1100 0000 1010 1000 1100 1000 0100 1001)

[0064] IP=192.168.200.73(1100 0000 1010 1000 1100 1000 0100 1001)

[0065] netmask=255.255.255.252(1111 1111 1111 1111 1111 1111 11111100)

[0066] gwip=192.168.200.74(1100 0000 1010 1000 1100 1000 0100 1010).

[0067] In one example, configuring the subnet mask of the Dynamic Host Configuration Protocol (DHCP) for the target communication module based on the mask configuration mode and IP address includes: obtaining the IP address; resolving the class of the IP address; finding the second subnet mask of the IP address based on the class; and configuring the second subnet mask as the subnet mask of the IP address.

[0068] There are three classes: A, B, and C. Subnet masks are dynamically assigned based on the class of the IP address. The subnet mask for a Class A IP address is 255.0.0.0, the subnet mask for a Class B IP address is 255.255.0.0, and the subnet mask for a Class C IP address is 255.255.255.0.

[0069] In one example, the subnet mask for the Dynamic Host Configuration Protocol (DHCP) that configures the target communication module based on the mask configuration mode and IP address includes: obtaining an IP address; obtaining a fixed static subnet mask; and configuring the static subnet mask as the subnet mask of the IP address.

[0070] When a static subnet mask is set, the WAN subnet mask will be the set static subnet mask after dialing.

[0071] The solution in this embodiment allows for selective configuration of the WAN port subnet mask based on the actual network conditions. This can be configured by issuing the relevant AT (Automatic Address Translation) before dialing. Depending on the situation, the AT can be configured in three ways: 1. Calculate the corresponding subnet mask based on the IP address; 2. Dynamically assign the subnet mask based on the IP address category: Class A IP addresses use a subnet mask of 255.0.0.0, Class B IP addresses use 255.255.0.0, and Class C IP addresses use 255.255.255.0; 3. Set a static subnet mask, which will be used after dialing.

[0072] Optionally, after configuring the subnet mask of the target communication module according to the mask configuration mode, the method further includes: creating a DHCP service process within the target communication module; and using the DHCP service process to configure cellular network card information for the host computer of the target communication module, wherein the cellular network card information includes IP address and subnet mask.

[0073] In Qualcomm platform applications, the netmgr configures the rmnet_data network interface card (NIC) information, enabling data services through this NIC. Internally, the module acts as a DHCP server, assigning appropriate IP addresses and netmasks to the host computer, thus achieving configurable WAN subnet mask functionality.

[0074] Figure 3 This is a flowchart illustrating the configuration of the subnet mask according to an embodiment of the present invention, including:

[0075] (1) Configure different WAN mask acquisition methods according to different network environment requirements. They can be configured into three modes: calculated based on IP address, calculated based on IP address class, and static mask address.

[0076] (2) Initiate a PDN dialing request. After successful activation, send the corresponding IP and netmsk information according to the WAN mask acquisition method.

[0077] (3) Configure the rmnet_data network card information in netmgr, which can be used for data services. The module internally acts as a DHCP server to assign corresponding IP addresses, netmasks, etc. to the host computer, thereby realizing the configurable WAN port subnet mask.

[0078] This embodiment addresses the challenge of a single WAN subnet mask calculation scheme in multi-scenario applications. It offers a set of selectable calculation schemes to ensure normal data service functionality after dialing in various network environments. Specifically, it resolves issues such as ping failures under different settings in private network environments and the inability to obtain IP addresses with multiple modules, significantly improving the compatibility of the communication module across different network environments. It enables normal data service operation after dialing in different network environments and allows for flexible configuration of the mask calculation method based on different network conditions, enhancing the compatibility and competitiveness of the communication module.

[0079] Through the above description of the embodiments, those skilled in the art can clearly understand that the methods according to the above embodiments can be implemented by means of software plus necessary general-purpose hardware platforms. Of course, they can also be implemented by hardware, but in many cases the former is a better implementation method.
