Database 20 includes, but is not limited to, any of a relational database, a non-relational database, an in-memory database, and the like.

Referring to fig. 3, a flowchart of an implementation of a network card management method according to an embodiment of the present application is illustrated by taking an electronic device in fig. 1 as an example, and includes the following steps.

S11: and in each detection period, the network card with the IP address allocated in the electronic equipment is determined as a candidate network card.

In some embodiments, the network card is a network card configured in an electronic device. The network cards include, but are not limited to, any one or more of an ethernet card, a wireless network card, a bluetooth network card, etc.

In some embodiments, a network card slot is configured on a motherboard of the electronic device, and the network card is inserted into the network card slot to implement network card configuration of the electronic device. The network card may be a network card following different communication protocols, for example, a wired LAN network card for connecting the electronic device to a local area network, a Wi-Fi network card for connecting a wireless hotspot, and a mobile communication network card for performing communication based on a mobile communication network, such as a 4G network card, etc.

In some related aspects, the electronic device detects the activation status of each network card, that is, detects the availability status of each network card, by instructing each network card to send a network report probe (Packet Internet Groper, ping) command to the server. Wherein the ping command is a command for testing a network connection condition. The ping command is a service command of an application layer operating in a TCP/IP network architecture, and is used to send an ICMP (Internet Control Message Protocol, internet message control protocol) request message to a specific target server, so as to test whether access to the server is possible or not. However, since some electronic devices have a simpler operating system configured on a motherboard, such as a bare computer system with a single chip microcomputer, an operating environment for detecting the activation state of multiple network cards cannot be provided, so the technical scheme for detecting the activation state of each network card by indicating each network card to send a ping command to a server cannot be applied to such electronic devices with simpler operating systems.

Based on the above problems, in the present 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 equipment is configured by the superior gateway equipment corresponding to each network card. The electronic equipment can pre-configure the driving program of each network card, and after the electronic equipment is started, the driving program of each network card is executed to control each network card to access the corresponding superior gateway equipment so as to obtain the IP address configured by the corresponding superior gateway equipment for each network card. For example, the router is an upper gateway device of a LAN network card or a Wi-Fi network card, and may allocate an IP address to the LAN network card or the Wi-Fi network card; the base station is an upper gateway device of the mobile communication network card, and can allocate an IP address for the mobile communication network card.

If the electronic device reads the IP address of the network card, it is determined that the network card establishes physical connection with a corresponding network card interface in the electronic device, and it is determined that the network card establishes communication with a corresponding upper gateway device, that is, it is determined that the network card is activated. At this time, 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. When the network card does not establish physical connection with a corresponding network card interface in the electronic device or the network card does not establish communication connection with a gateway corresponding to the network card, the electronic device cannot acquire the IP address of the network card, that is, the network card is not activated and is in an unavailable state.

In order to ensure that the electronic equipment and the server normally communicate, the electronic equipment selects the activated network card as a candidate network card and does not process the unactivated network card.

In some embodiments of the present application, determining a network card with an allocated IP address in an electronic device as a candidate network card includes: and reading the IP address of each network card according to the network card interface address of each network card, and determining the network card corresponding to the read IP address as a candidate network card.

In some embodiments, the network card interface address includes a hardware address or a physical address of the network card, i.e., a media access control (Media Access Control, MAC) address. The network card interface address is used for uniquely identifying the network card.

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

In the process of acquiring the IP address of each network card, the electronic device may send the packet to the upper gateway device by packing the network card interface address for uniquely identifying the network card into a data packet. The upper gateway equipment receives the data packet, analyzes the data packet to obtain the network card interface address of the network card, allocates an IP address for the network card, and returns the IP address allocated for the network card to the network card according to the network card interface address of the network card. When the IP address returned by the superior gateway equipment is received, the network card is in an activated state.

However, if the physical connection between the network card and the corresponding network card interface in the electronic device is disconnected, or the communication connection between the network card and the corresponding upper gateway device is disconnected, the network card cannot acquire the corresponding IP address. At this time, the network card is in an inactive state.

In some embodiments, since the electronic device may enable the network card for communication only if the network card is activated, to ensure that the finally enabled network card is a network card in an available state, the electronic device determines only the network card in an activated state as a candidate network card.

S12: and determining the target network card from the candidate network cards based on the priorities corresponding to the candidate network cards.

In some embodiments, the priority is used to characterize the order in which the candidate network cards are enabled. The higher the priority candidate network cards, the more preferentially enabled. The target network card refers to the network card with the highest priority in the candidate network cards.

In some embodiments, the electronic device may determine a plurality of candidate network cards in each detection period. Each candidate network card establishes physical connection with a corresponding network card interface in the electronic equipment, and establishes communication with the superior gateway equipment corresponding to the candidate network card, namely, each candidate network card is an activated network card in an available state.

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 plurality of candidate network cards.

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

In some embodiments, the user may determine the priority of each candidate network card in the electronic device according to the communication stability and the communication cost of the candidate network card, where the more stable the communication and the lower the communication cost, the higher the priority.

In some embodiments of the present application, if the electronic device does not detect the network card with the allocated IP address, the first preset network card is determined as the target network card.

In some embodiments, there may be cases where all network cards of the electronic device are inactive. At this time, in order to ensure the normal operation of the electronic device, the electronic device starts the first preset network card as a target network card to perform communication. The first preset network card is a network card configured in the 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 a network card with the highest priority in the electronic device. For example, assuming that the priority of the ethernet card is set to be highest in the electronic device, the electronic device may determine the ethernet card as the target network card when the network card with the allocated IP address is not detected.

S13: and using the target network card to communicate.

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

In the network card management method provided by the embodiment of the application, if the electronic device reads the IP address of the network card, it can be determined that the network card establishes physical connection with the corresponding network card interface in the electronic device, and that the network card establishes communication with the corresponding upper gateway device, that is, that the network card is activated, so that the electronic device determines the available state of each network card by acquiring the IP address of each network card in each detection period, thereby determining the currently available candidate network card. Because the electronic device may determine multiple candidate network cards in each detection period, and only one network card can provide internet service for the electronic device at the same time, the electronic device determines a target network card to be started from the candidate network cards based on the priority of each candidate network card, and uses the target network card for communication. Therefore, the electronic equipment periodically and dynamically determines the target network card capable of communicating under the condition of configuring the multiple network cards, long-time network interruption caused by long-time use of the electronic equipment due to abnormal network cards is avoided to a certain extent, and the working efficiency of the electronic equipment is ensured.

Fig. 4 is a flowchart of a method for determining a target network card according to an embodiment of the present application. As shown in fig. 4, determining the target network card from the candidate network cards based on the priorities corresponding to the candidate network cards includes the following steps.

S21: and determining a network card state digital sequence based on each candidate network card.

In some embodiments, the network card status digital 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 second preset values. Because the candidate network card is an activated network card in the electronic device, the first preset value is used for representing the activated network card, and the second preset value is used for representing the unactivated network card. For example, the first preset value may be represented by 1 and the second may be represented by 0.

In some embodiments, the electronic device manages all network cards in the electronic device by matching the network card status bitmap with the network card priority sequence. The network card state bitmap refers to a collection of network card state digital sequences, and is used for representing all states of all network cards of the electronic device. The number and types of network cards in the electronic device are different, and the corresponding network card status bitmaps are also different.

The electronic equipment is configured with 3 network cards, which are respectively: examples of Wi-Fi network card, LAN network card, 4G network card, the network card status bitmap of the electronic device is shown in Table 1 below.

Table 1 network card status bitmap

Wi-Fi network card	4G network card	LAN network 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 respectively correspond to one flag bit, where the first flag bit indicates an activation state of the Wi-Fi network card, the second flag bit indicates an activation state of the 4G network card, and the third flag bit indicates an activation state of the LAN network card. Because each network card has only two states, namely activated and deactivated, as shown in table 1, the electronic device uses 0 to represent the state that the network card is not activated and uses 1 to represent the state that the network card is activated, so if three network cards are configured in the electronic device, the network card state bitmap of the electronic device comprises 2 x 2 states, namely 8 network card state digital sequences. As shown in table 1, the network card status bitmap includes 8 network card status number sequences of 000, 100, 010, 001, 110, 101, 011, 111, respectively. If the network card status number sequence is 000, it indicates that all network cards are not activated.

In some embodiments, since all the candidate network cards are all activated network cards determined by the electronic device, the electronic device may determine the activation status of all the network cards in the electronic device based on each candidate network card. The network card state bitmap refers to a collection of network card state digital sequences and is used for representing all states of all network cards of the electronic device, so that the electronic device can obtain the network card state digital sequences corresponding to candidate network cards in a matching manner from the network card state bitmap according to the activation states of all network cards. In the example shown in table 1, if the electronic device determines that the candidate network cards include the Wi-Fi network card and the 4G network card, the network card status digital sequence corresponding to each candidate network card is 110. If the electronic device does not detect the network card with the allocated IP address, that is, it is determined that all network cards are not activated, the network card status digital sequence of the electronic device is 000.

In some embodiments, the electronic device detects the activation state of each network card at regular time by starting a timer, and each detected activation state of each network card necessarily corresponds to a certain item in the network card status bitmap. The electronic device binds the network card status bitmap with the network card priority list, so that management of all network cards can be realized.

S22: and acquiring a network card priority sequence corresponding to the network card state digital sequence, and determining a target network card according to the network card priority sequence.

In some embodiments, each network card status number sequence corresponds to a network card priority sequence. The network card priority sequence is used for representing the priority of each activated network card in the corresponding network card state digital sequence. Because the candidate network cards may be different in different detection periods, the network card status number sequence corresponding to each candidate network card in different detection periods may also be different, and thus the corresponding network card priority sequence may also be different. That is, the network card priority sequence of the electronic device is dynamically updated as the candidate network card changes.

In some embodiments, the rule for determining the priority sequence of the network cards follows the communication stability and communication cost of each candidate network card, and the more stable the communication and the lower the communication cost of the candidate network card, the higher the priority.

In some embodiments, after determining the network card status digital sequence corresponding to each candidate network card, the electronic device determines the network card priority sequence corresponding to each candidate network card according to the corresponding relationship between the network card status digital 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 above table 1 example, table 2 below shows a map of the correspondence between the network card status bitmap and the network card priority list. The network card priority list comprises 8 network card priority sequences, and each network card priority sequence corresponds to each network card state digital sequence in the table 1 one by one. The table 2 also includes a network card priority statement, where the network card priority statement is used to describe each network card priority sequence.

Table 2 correspondence chart 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. The network card priority sequence comprises the priority of each activated network card in the corresponding network card state number sequence, and the smaller the number is, the higher the priority is. For example, as shown in table 2, when determining that the network card status number sequence is 111, the electronic device determines that the corresponding network card priority sequence is 1.lan network card, 2.wi-Fi network card, 3.4G network card, and according to the network card priority statement, the LAN network card priority is highest, wi-Fi network card times, and 4G network card priority is lowest.

As can be seen from table 2, after determining the network card priority sequence corresponding to each candidate network card, the electronic device determines the priority of each candidate network card, so as to determine the target network card for communication according to the priority of each candidate network card.

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

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

In some embodiments, after determining the network card priority sequence corresponding to each candidate network card, the electronic device determines the priority of each candidate network card, so as to ensure high-speed data transmission of the electronic device, and the candidate network card with the first priority is prioritized to be used as a target network card for communication. As shown in table 2 above, when the network card status number sequence is determined to be 111, the electronic device preferably 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 detects only one network card with an allocated IP address, that is, determines a candidate network card, the candidate network card is a network card with a first priority, that is, a target network card, and the electronic device enables the candidate network card to communicate. As shown in table 2 above, when the network card status digital sequence is determined to be 100, since only the Wi-Fi network card is activated, the Wi-Fi network card in the corresponding network card priority sequence is the first priority, and the electronic device enables the Wi-Fi network card to communicate.

In some embodiments, a default network card (i.e., the first preset network card) is further provided in the electronic device. The default network card is a network card configured in the electronic device. When the electronic equipment does not detect the network card with the allocated IP address, namely, the electronic equipment determines that all the network cards are not activated, the electronic equipment takes the default network card as the network card with the first priority in the corresponding network card priority sequence, and starts the target network card to communicate. As shown in table 2 above, the electronic device determines the Wi-Fi network card as a default network card. And when the electronic equipment does not acquire the candidate network cards, namely, all the network cards are not activated, determining that the network card state digital sequence of the electronic equipment is 000. At this time, the network card of the first priority of the network card priority sequence corresponding to the network card status digital 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 particular priority. After determining the candidate network cards, the electronic device may directly query the priorities corresponding to the candidate network cards, and select the candidate network card with the highest priority as the target network card.

Fig. 5 is a flowchart of a network card management method according to another embodiment of the present application. As shown in fig. 5, the network card management method provided in this embodiment includes the following steps.

S31: and in each detection period, the network card with the IP address allocated in the electronic equipment is determined as a candidate network card.

S32: and determining the target network card from the candidate network cards based on the priorities corresponding to the candidate network cards.

S33: and using the target network card to communicate.

The specific implementation manner of step S31 to step S33 may refer to the content of the specific embodiment of step S11 to step S13 in fig. 3.

S34: and if the communication abnormality of the target network card is detected, taking the candidate network card corresponding to the next priority of the target network card in the network card priority sequence as a new target network card.

In some embodiments, the network card priority sequence includes priorities of the candidate network cards. As shown in table 2 above, when the network card status digital sequence 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, 3.4G network card, and according to the network card priority statement, at this time, the LAN network card priority is highest, wi-Fi network card times, and 4G network card priority is lowest.

However, the candidate network card of the first priority may not normally perform communication due to a network failure or a hardware failure. At this time, in order to ensure the working stability of the electronic device, the electronic device enables the candidate network card of the next priority in the network card state digital sequence as a new target network card.

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

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

S35: and using the new target network card to communicate.

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, and communicate with other network devices or servers.

Fig. 6 is a flowchart of a network card management method according to 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: and in each detection period, the network card with the IP address allocated in the electronic equipment is determined as a candidate network card.

S42: and determining the target network card from the candidate network cards based on the priorities corresponding to the candidate network cards.

S43: and using the target network card to communicate.

The specific implementation manner of step S41 to step S43 may refer to the content of the specific embodiment of step S11 to step S13 in fig. 3.

S44: judging whether the target network card is a second preset network card or not.

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 a network card corresponding to a mobile communication network is configured in the electronic device, the network card is generally configured as a network card with the lowest priority because of higher tariffs of the mobile communication network.

In some embodiments, because the network card of the mobile communication network is generally used to communicate with a Wi-Fi network card or a LAN network card at a higher communication cost, in order to save the communication cost, the electronic device further determines whether the target network card is a network card of the mobile communication network after determining the target network card.

In some embodiments, if the target network card is detected to be a network card of the mobile communication network and it is determined that other network cards are not activated, the electronic device accelerates the network card detection frequency to determine whether the network card of the non-mobile communication network is activated as soon as possible, so as to switch to the network card of the other non-mobile communication network in time for free communication, thereby realizing control of communication cost.

S45: and when the target network card is a second preset network card, the detection period is adjusted to be a first duration.

In some embodiments, when the target network card is a network card of the mobile communication network, the electronic device may speed up the network card detection frequency by decreasing the duration of the detection period to the first duration. The first time length is set by user definition, and the value of the first time length is not limited by the application.

S46: and when the target network card is not the second preset network card, adjusting the detection period to be a second duration.

In some embodiments, when it is determined that the target network card is a network card of a non-mobile communication network, for example, a Wi-Fi network card, a LAN network card, or the like, the electronic device adjusts the detection period to a second duration. Because the target network card is the network card of the non-mobile communication network, the cost of using the target network card to communicate is lower, the electronic equipment does not need to accelerate the network card detection frequency, and the duration of the detection period can be recovered to be a second duration, and the second duration is longer than the first duration. The second time length is set by user definition, and the specific value of the second time length is not limited by the application.

In some embodiments, if a fixed detection period is preconfigured before determining whether the target network card is the second preset network card, when it is determined that the target network card is a network card of the non-mobile communication network, the electronic device maintains the preset detection period without adjusting the same.

In some embodiments, the electronic device may perform steps S44 to S46 after determining the target network card from the candidate network cards based on the priorities corresponding to the candidate network cards.

It should be understood that the sequence number of each step in the foregoing embodiment does not mean that the execution sequence of each process should be determined by the function and the internal logic, and should not limit the implementation process of the embodiment of the present application.
