Please refer to FIG. 3 , which is an implementation flowchart of the network card management method provided by the embodiment of the present application. Taking the electronic device in FIG. 1 as an example for illustration, the method includes the following steps.

S11: In each detection cycle, determine a network card that has been assigned an IP address in the electronic device as a candidate network card.

In some embodiments, the network card is a network card configured in an electronic device. The network card includes but is not limited to any one or more of an Ethernet card, a wireless network card, a Bluetooth network card, and the like.

In some embodiments, a network card slot is configured on the motherboard of the electronic device, and the network card configuration of the electronic device can be realized by inserting the network card into the network card slot. Wherein, the network card may be a network card following different communication protocols, for example, a wired LAN network card used to connect electronic devices to a local area network, a Wi-Fi network card used to connect to a wireless hotspot, and a mobile communication network card for communication based on a mobile communication network, such as 4G Network card, etc.

In some related solutions, the electronic device instructs each network card to send a Packet Internet Groper (ping) command to the server to detect the activation state of each network card, that is, to detect the availability state of each network card. Wherein, the ping command is a command for testing the network connection status. The ping command is a service command working in the application layer of the TCP/IP network architecture, and is used to send an ICMP (Internet ControlMessage Protocol, Internet Message Control Protocol) request message to a specific target server to test whether the server can be pinged. Access etc. However, since the main boards of some electronic devices are configured with relatively simple operating systems, such as single-chip bare-metal systems, etc., it is impossible to provide an operating environment for detecting the activation status of multiple network cards. Therefore, each network card is detected by instructing each network card to send a ping command to the server. The technical scheme of the activated state cannot be applied to electronic devices with relatively simple operating systems of this type.

Based on the above problems, in this solution, the electronic device determines the activation status of each network card by reading the IP address of each network card. The IP address of each network card in the electronic device is configured by the upper-level gateway device corresponding to each network card. The electronic device can pre-configure the driver program of each network card. After the electronic device is turned on, the driver program of each network card is executed to control each network card to access the corresponding upper-level gateway device, so as to obtain the IP address configured by the corresponding upper-level gateway device for each network card. For example, a router is an upper-level gateway device of a LAN network card or a Wi-Fi network card, and can assign an IP address to a LAN network card or a Wi-Fi network card; a base station is an upper-level gateway device of a mobile communication network card, and can assign an IP address to a mobile communication network card.

If the electronic device reads the IP address of the network card, it is determined that the network card has established a physical connection with the corresponding network card interface in the electronic device, and it is determined that the network card has established communication with the corresponding upper-level gateway device, that is, it is determined that the network card is activated. At this point, the electronic device determines the activated network card as a candidate network card.

In other embodiments, if the electronic device does not read the IP address of the network card, it is determined that the network card is not activated. Among them, when the network card has not established a physical connection with the corresponding network card interface in the electronic device, or the network card has not established a communication connection with the gateway corresponding to the network card, the electronic device cannot obtain the IP address of the network card, that is, the network card has not been activated. , is in an unavailable state.

In order to ensure normal communication between the electronic device and the server, the electronic device selects an activated network card as a candidate network card, and does not process an inactive network card.

In some embodiments of the present application, determining the network card that has been assigned an IP address in the electronic device as a candidate network card includes: reading the IP address of each network card according to the network card interface address of each network card, and corresponding to the read IP address The network card is determined as a candidate network card.

In some embodiments, the interface address of the network card includes a hardware address or a physical address of the network card, that is, a Media Access Control (Media Access Control, MAC) address. The network card interface address is used to uniquely identify the network card.

In some embodiments, the IP address of each network card in the electronic device is configured by the upper-level gateway device corresponding to each network card. Therefore, the electronic device can control the network card to access the corresponding upper-level gateway device to request the upper-level gateway device to allocate an IP address for the network card.

In the process of obtaining the IP address of each network card, the electronic device may send the data packet to the upper-level gateway device by packaging the interface address of the network card for uniquely identifying the network card. The upper-level gateway device receives the data packet, analyzes the data packet to obtain the network interface address of the network card, allocates an IP address for the network card, and returns the IP address assigned to the network card to the network card according to the network interface address of the network card. When receiving the IP address returned by the upper-level gateway device, the network card is activated.

However, if the physical connection between the network card and the corresponding network card interface in the electronic device is broken, or the communication connection between the network card and the corresponding upper-level gateway device is broken, the network card cannot obtain the corresponding IP address. At this time, the network card is not activated.

In some embodiments, the electronic device can enable the network card for communication only when the network card is activated. Therefore, in order to ensure that the finally enabled network card is an available network card, the electronic device only determines the activated network card as a candidate network card.

S12: Based on the priorities corresponding to each candidate network card, determine a target network card from each candidate network card.

In some embodiments, the priority is used to characterize the activation order of each candidate network card. The candidate NIC with higher priority will be enabled first. The target network card refers to the network card with the highest priority among the candidate network cards.

In some embodiments, in each detection cycle, the electronic device may determine multiple candidate network cards. Each candidate network card has established a physical connection with the corresponding network card interface in the electronic device, and establishes communication with the upper-level gateway device corresponding to the candidate network card, that is, each candidate network card is an activated and available network card.

However, since the electronic device can only use one candidate network card to communicate with other network devices or servers at the same time, the electronic device needs to determine a target network card from the multiple candidate network cards.

Based on this, the priority of each candidate network card can be preset in the electronic device. When the electronic device determines multiple candidate network cards, it may determine a target network card from the multiple candidate network cards based on the priority of each candidate network card.

In some embodiments, the user can determine the priority of each candidate network card in the electronic device according to the communication stability and communication cost of the candidate network cards, wherein the candidate network card with more stable communication and lower communication cost has a higher priority.

In some embodiments of the present application, if the electronic device does not detect a network card that has been assigned an IP address, then determine the first preset network card as the target network card.

In some embodiments, there may be a situation that all network cards of the electronic device are network cards in an inactive state. At this time, in order to ensure the normal operation of the electronic device, the electronic device uses the first preset network card as the target network card for communication. Wherein, the first preset network card is a network card configured in an electronic device, including but not limited to a Wi-Fi network card, a Bluetooth network card, and the like.

In some embodiments, in order to ensure the communication stability of the electronic device, the first preset network card may be the network card with the highest priority in the electronic device. For example, assuming that the priority of setting the Ethernet card in the electronic device is the highest, the electronic device may determine the Ethernet card as the target network card when no network card with an IP address is detected.

S13: use the target network card to communicate.

In some embodiments, the target network card is the network card with the highest priority determined by the electronic device from the candidate network cards.

In some embodiments, after the electronic device determines the target network card, it enables the target network card to establish a communication connection with other network devices or servers to realize communication and data interaction. When data needs to be sent to other network devices or servers, the electronic device encapsulates the data to be sent into network data packets, and sends the network data packets to other network devices or servers through the target network card.

In the network card management method provided by the embodiment of the present application, if the electronic device reads the IP address of the network card, it can be determined that the network card has established a physical connection with the corresponding network card interface in the electronic device, and it can be determined that the network card is connected to the corresponding network card. The corresponding upper-level gateway device establishes communication, that is, determines that the network card is activated, so the electronic device determines the availability status of each network card by obtaining the IP address of each network card in each detection cycle, thereby determining the currently available candidate network card. Since in each detection cycle, the electronic device may determine multiple candidate network cards, but only one network card can provide Internet access services for the electronic device at the same time, so the electronic device determines the candidate network card based on the priority of each candidate network card. A target NIC to enable, use the target NIC for communication. In this way, in the case of configuring multiple network cards, the electronic device periodically and dynamically determines the target network card that can communicate. work efficiency.

Please refer to FIG. 4 , which is an implementation flowchart of the method for determining a target network card provided by the embodiment of the present application. As shown in FIG. 4 , based on the priority corresponding to each candidate network card, determining a target network card from each candidate network card includes the following steps.

S21: Determine a network card status digital sequence based on each candidate network card.

In some embodiments, the network card status number sequence includes flag bits corresponding to different network cards, the value of the flag bit corresponding to each candidate network card is a first preset value, and the values of other flag bits are a second preset value. Since the candidate network card is an activated network card in the electronic device, the first preset value is used to represent an activated network card, and the second preset value is used to represent an inactive network card. For example, the first preset value can be represented by 1, and the second preset value can be represented by 0.

In some embodiments, the electronic device manages all the network cards in the electronic device through the network card status bitmap and the priority sequence of the network cards. Wherein, the network card state bitmap refers to a collection of network card state digital sequences, which is used to represent all states of all network cards of the electronic device. The number and type of network cards in the electronic device are different, and the corresponding network card status bitmaps are also different.

Taking an electronic device configured with three network cards: a Wi-Fi network card, a LAN network card, and a 4G network card as an example, the network card status bitmap of the electronic device is shown in Table 1 below.

Table 1 NIC status bitmap

Wi-Fi card 4G network card LAN card 0 0 0 1 0 0 0 1 0 0 0 1 1 1 0 1 0 1 0 1 1 1 1 1

As shown in Table 1, the Wi-Fi network card, the LAN network card, and the 4G network card correspond to a flag respectively, wherein the first flag represents the activation state of the Wi-Fi network card, the second flag represents the activation state of the 4G network card, and the third flag represents the activation state of the 4G network card. The flag bit represents the activation state of the LAN network card. Since each network card has only two states of activated and inactive, as shown in Table 1, the electronic device uses 0 to represent the state of the network card not activated, and 1 to represent the state of the network card activated. Therefore, if the electronic device is configured with three network cards, Then the network card state bitmap of the electronic device includes 2*2*2 states, that is, includes 8 network card state digital sequences. As shown in Table 1, the network card status bitmap includes 8 network card status digital sequences, which are 000, 100, 010, 001, 110, 101, 011, and 111, respectively. Wherein, if the number sequence of the network card status is 000, it indicates that all network cards are not activated.

In some embodiments, since all candidate network cards are all activated network cards determined by the electronic device, the electronic device can determine the activation status of all network cards in the electronic device based on each candidate network card. And because the network card status bitmap refers to the collection of network card status digital sequences, which is used to represent all the states of all network cards of the electronic device, so the electronic device can match the network card corresponding to each candidate network card according to the activation status of all network cards from the network card status bitmap State number sequence. As shown in Table 1 above as an example, if the electronic device determines that the candidate network cards include a Wi-Fi network card and a 4G network card, then the network card status number sequence corresponding to each candidate network card is 110. If the electronic device does not detect a network card that has been assigned an IP address, that is, it is determined that all network cards are not activated, the digital sequence of the network card status of the electronic device is 000.

In some embodiments, the electronic device regularly detects the activation status of each network card by starting a timer, and each detected activation status of each network card must correspond to an item in the network card status bitmap. The electronic device binds the network card status bitmap with the network card priority list, so that all network cards can be managed.

S22: Obtain a network card priority sequence corresponding to the network card status number sequence, and determine a target network card according to the network card priority sequence.

In some embodiments, each NIC status number sequence corresponds to a NIC priority sequence. The network card priority sequence is used to represent the priority of each activated network card in the corresponding network card status number sequence. Since the candidate network cards may be different in different detection cycles, the sequence of network card status numbers corresponding to each candidate network card in different detection cycles may also be different, and thus the corresponding network card priority sequences may also be different. That is, the network card priority sequence of the electronic device is dynamically updated as the candidate network cards change.

In some embodiments, the determination rule of the network card priority sequence follows the communication stability and communication cost of each candidate network card, and the candidate network card with more stable communication and lower communication cost has a higher priority.

In some embodiments, after the electronic device determines the network card status number sequence corresponding to each candidate network card, it determines the network card priority sequence corresponding to each candidate network card according to the corresponding relationship between the network card status number sequence and the network card priority sequence. The electronic device can determine the priority of each candidate network card according to the network card priority sequence corresponding to each candidate network card, and determine the target network card according to the priority of each candidate network card.

Based on the example in Table 1 above, Table 2 below is a chart showing the correspondence between the network card status bitmap and the network card priority list. Wherein, the network card priority list includes 8 network card priority sequences, and each network card priority sequence corresponds to each network card status number sequence in Table 1 one by one. Table 2 also includes a network card priority statement, which is used to describe the priority sequence of each network card.

Table 2 Correspondence between network card status bitmap and network card priority list

As shown in Table 2, each network card status number sequence corresponds to a network card priority sequence and a corresponding network card priority statement. Wherein, the network card priority sequence includes the priority of each activated network card in the corresponding network card status number sequence, and the smaller the number, the higher the priority. For example, as shown in Table 2, when the number sequence of the network card status is determined to be 111, the electronic device determines that the corresponding network card priority sequence is 1. LAN network card, 2. Wi-Fi network card, and 3.4G network card. According to the network card priority declaration, this , the LAN network card has the highest priority, followed by the Wi-Fi network card, and the 4G network card has the lowest priority.

According to Table 2, after the electronic device determines the network card priority sequence corresponding to each candidate network card, it determines the priority of each candidate network card, and then determines the target network card for communication according to the priority of each candidate network card.

In some embodiments of the present application, determining the target network card according to the network card priority sequence includes: using the candidate network card corresponding to the first priority in the network card priority sequence as the target network card.

In some embodiments, the candidate network card with the first priority is the candidate network card with the highest priority.

In some embodiments, after the electronic device determines the network card priority sequence corresponding to each candidate network card, it determines the priority of each candidate network card. In order to ensure high-speed data transmission of the electronic device, the candidate network card with the first priority is given priority as the target network card to communicate. As shown in Table 2 above, when it is determined that the number sequence of the network card status is 111, the electronic device preferentially selects the LAN network card with the first priority as the target network card for communication according to the corresponding network card priority sequence.

In some embodiments, if the electronic device only detects a network card that has been assigned an IP address, that is, determines a candidate network card, then the candidate network card is the network card with the first priority, that is, the target network card, and the electronic device enables the network card. Candidate NICs for communication. As shown in Table 2 above, when it is determined that the number sequence of the network card status is 100, since only the Wi-Fi network card is activated, at this time, the Wi-Fi network card is the first priority in the corresponding network card priority sequence, and the electronic device enables the Wi-Fi network card. -Fi network card for communication.

In some embodiments, a default network card (ie, the above-mentioned first preset network card) is also set in the electronic device. The default network card is a network card configured in the electronic device. When the electronic device does not detect a network card with an assigned IP address, that is, when it is determined that all network cards are not activated, the electronic device takes the default network card as the first priority network card in the priority sequence of the corresponding network card, and enables the target network card to communicate . As shown in Table 2 above, the electronic device determines the Wi-Fi network card as the default network card. When the electronic device does not obtain candidate network cards, that is, when it is determined that all network cards are not activated, it is determined that the digital sequence of the network card status of the electronic device is 000. At this time, the network card with the first priority in the network card priority sequence corresponding to the network card status number sequence is a Wi-Fi network card, and the electronic device enables the Wi-Fi network card to communicate.

In some embodiments, each network card in the electronic device may correspond to a specific priority. After determining the candidate network cards, the electronic device may directly query the priorities corresponding to each candidate network card, and select the candidate network card with the highest priority as the target network card.

Please refer to FIG. 5 , which is an implementation flowchart of a network card management method provided by another embodiment of the present application. As shown in FIG. 5 , the network card management method provided by this embodiment includes the following steps.

S31: In each detection cycle, determine a network card that has been assigned an IP address in the electronic device as a candidate network card.

S32: Based on the priority corresponding to each candidate network card, determine a target network card from each candidate network card.

S33: use the target network card to communicate.

Wherein, the specific implementation manner of step S31 to step S33 can refer to the content of the specific embodiment of step S11 to step S13 in FIG. 3 .

S34: If it is detected that the communication of the target network card is abnormal, the candidate network card corresponding to the next priority of the target network card in the network card priority sequence is used as a new target network card.

In some embodiments, the NIC priority sequence includes the priority of each candidate NIC. As shown in Table 2 above, when it is determined that the number sequence of the network card status is 111, the electronic device determines that the corresponding network card priority sequence is 1. LAN network card, 2. Wi-Fi network card, and 3.4G network card. According to the network card priority declaration, At this time, the LAN network card has the highest priority, followed by the Wi-Fi network card, and the 4G network card has the lowest priority.

However, the candidate network card with the first priority may not be able to communicate normally due to reasons such as network failure or hardware failure. At this time, in order to ensure the stability of the electronic device, the electronic device uses the candidate network card with the next priority in the network card status number sequence as the new target network card.

Based on the above example, when the number sequence of the network card status is determined to be 111, according to the corresponding network card priority sequence, the electronic device preferentially enables the LAN network card with the first priority as the target network card for communication. When it is detected that the LAN network card of the first priority fails to communicate normally, the electronic device enables the Wi-Fi network card of the next priority as a new target network card for communication. In some embodiments, in the same detection period, if the Wi-Fi network card with the next priority cannot communicate normally, the electronic device may switch to a 4G network card with a lower priority for communication.

In other embodiments of the present application, if it is detected that the target network card is abnormal in communication and there is no candidate network card corresponding to the next priority in the network card priority sequence, the electronic device may trigger an alarm to prompt the user that the communication is abnormal.

S35: Use the new target network card for communication.

In some embodiments, if the electronic device determines a new target network card, the new target network card is controlled to establish a communication connection with other network devices or servers to communicate with other network devices or servers.

Please refer to FIG. 6 , which is an implementation flowchart of a network card management method provided in another embodiment of the present application. As shown in FIG. 6 , the network card management method provided in this embodiment includes the following steps.

S41: In each detection cycle, determine a network card that has been assigned an IP address in the electronic device as a candidate network card.

S42: Based on the priority corresponding to each candidate network card, determine a target network card from each candidate network card.

S43: Use the target network card to communicate.

Wherein, the specific implementation manner of step S41 to step S43 can refer to the content of the specific embodiment of step S11 to step S13 in FIG. 3 .

S44: Determine whether the target network card is the second default network card.

In some embodiments, the second preset network card is a network card corresponding to a mobile communication network, such as a 4G network card. When the network card corresponding to the mobile communication network is configured in the electronic device, the network card is usually configured as the network card with the lowest priority because the tariff of the mobile communication network is relatively high.

In some embodiments, since the communication cost of using a network card of a mobile communication network is higher than that of a Wi-Fi network card or a LAN network card, in order to save communication costs, the electronic device further determines the target network card after determining the target network card. Whether the network card is a network card of a mobile communication network.

In some embodiments, if it is detected that the target network card is a network card of a mobile communication network, and it is determined that other network cards are not activated, the electronic device will speed up the detection frequency of the network card to determine whether the network card of the non-mobile communication network is activated as soon as possible, Thereby switching to network cards of other non-mobile communication networks for free communication in time, so as to realize the control of communication cost.
