At present, electronic devices with dual systems, especially electronic devices with two systems capable of running simultaneously, are becoming more and more popular. To enable the two systems to run at the same time, the current method is mainly to use two motherboards, one for each motherboard, because each system has a separate Central Processing Unit (CPU), so that two The system can run at the same time. Therefore, in order to make both systems available, an integrated network card is required on each motherboard. This results in each system needing to access the network through the corresponding network card. Take the current common dual-system electronic device with Windows operating system and Android operating system as an example. If it is a wired network, use the Android operating system to take one. The network cable needs to be connected to a network cable (or the interface for replacing the network cable) to use the Windows operating system, which results in inconvenient use. To this end, the present invention provides a solution for network sharing within an electronic device. A schematic structural diagram of an electronic device according to an embodiment is shown in FIG.

The electronic device 100 includes a network expansion module 110, a first control module 120, and a second control module 130. The network extension module 110 includes a first interface 111 and a second interface 112. The first control module 120 is equipped with a first operating system, and the second control module 130 is equipped with a second operating system. Of course, the first operating system and the second operating system may be the same or different. For example, one is a Windows operating system. Another is the Android operating system, or both are windows The operating system or the Android operating system, etc., the present invention does not limit the type of the operating system.

The first control module 120 includes a first network card module 121 and a third network card module 122, and the second control module 130 includes a second network card module 131. The functions of the network card module include: 1. Encapsulating the data of the control module into frames, and transmitting the data to the network through a network cable (wired network) or electromagnetic waves (wireless network); 2. receiving frames transmitted by other devices on the network, and The frames are reassembled into data and sent to the control module in which they are located.

The third network card module 122 is configured to connect to an external network. For example, the third network card module 122 has an RJ45 interface. When the network cable is inserted into the interface, the third network card module 122 can access the wired network, and the third network card module 122 can be a USB. - PHY chip, etc., the USB-PHY chip mainly converts the signal of the RJ45 into a USB signal; of course, the third network card module 122 capable of accessing the wireless network can also be used, and the third network card module 122 can be a wireless network card, etc., or The third network card module 122 that can be connected to the wired network or the wireless network is not limited by the present invention. The first network card module 120 is connected to the first interface 111, the second network card module 131 is connected to the second interface 112, and the first network card module 120 and the second network card module 131 are capable of data communication through the network expansion module 110. The network expansion module 110 can be a switch, a router, a hub, etc. The first network card module 121 can be an Ethernet-PHY chip or the like. The Ethernet-PHY chip can convert the network signal into a signal transmitted by the RJ45 and input it to the switch. The second network card module 131 can be a USB-PHY chip or the like, and can access the network output by the switch to the second control module 130. Therefore, when the first control module 120 accesses the network, the second control module 130 can also access the network. .

When the third network card module 122 is connected to the external network, the first control module 120 starts the network sharing and the dynamic host configuration protocol (DHCP) service, and generates the shared network through the first network card module 121. The second control module 130 passes the second network card module 131. The network extension module 110 accesses the shared network.

DHCP (Dynamic Host Configuration Protocol) is a LAN network protocol that works with the UDP protocol. It has two main purposes: to automatically assign an IP address to the internal network or network service provider to the internal network administrator. As a means of central management of all computers. The DHCP-enabled control module can automatically assign IP addresses, masks, and default gateways to other control modules. Therefore, after the first control module 120 starts the network sharing function, the second control module 130 can access the shared network for network communication. When the second control module 130 wants to send data to the network, the second network card module 131 encapsulates the data into a frame, and then sends the data frame to the network expansion module 110, and the network expansion module 110 forwards the data frame to the first control module. 120. The first control module 120 sends the data frame to the network again. The process of sending the data returned from the network to the second control module 130 is: the third network card module 122 receives the data frame returned from the network, and the data is received. The frame is sent to the network extension module 110 through the first network card module 120. The network extension module 110 forwards the data frame to the second network card module 131, and the second network card module 131 reassembles the frames into data for use by the second control module 131.

Thus, when a control module (first control module 120) accesses the external network, by opening the network sharing function, other control modules (eg, the second control module 130) of the electronic device 100 can communicate with the Internet through the shared network.

After the third network card module 122 is connected to the external network, the first control module 120 and the second control module 130 can be connected to the network. In order to prevent the entire electronic device 100 from being connected to the network after the third network card module 122 fails, as shown in FIG. 2 As shown, the second network module 232 can be connected to the external network in the second control module 230. Therefore, the electronic device 200 can also access the external network through the fourth network card module 232, and the second control module 230 activates the network sharing function. The second shared network module 231 is configured to generate a shared network, so that the first control module 220 accesses the shared network through the first network card module 221 and the network expansion module 210.

Of course, the first control module 220 can access the external network through the third network card module 222, and the second control module 230 can access the external network through the fourth network card module 232, so that the network sharing function does not need to be started, the first control module 220 and The second control module 230 is in direct data communication with the external network. Generally, the external network accessed by the third network card module 222 and the fourth network card module 232 is the same, for example, a 20M network provided by the same router, but may also be different, for example, one accessing a 20M network. The other access is a 100M network. Therefore, in order to improve network utilization, when the third network card module 222 and the fourth network card module 232 are both connected to the external network, the performance of the external network is compared to determine whether to re-establish Configure network sharing features, and more.

The second external network is accessed by the third network card module 222, and the second external network is used as the second external network. The first control module 220 performs network performance on the first external network and the second external network. Comparing, determining whether to reconfigure the network sharing function according to the comparison result, for example, when the bandwidth of the first external network is greater than the bandwidth of the second external network, the network sharing function is initiated by the first control module 220; when the bandwidth of the first external network is less than When the bandwidth of the second external network is reached, the network sharing function is initiated by the second control module 230. Of course, the user can also set other rules. For example, the control module that accesses the external network directly communicates with the external network, or starts the network sharing function by using a control module with a small external network bandwidth.

Generally, the third network card module 222 and the fourth network card module 232 have a certain time difference when accessing the external network. For example, the third network card module 222 is first inserted into the network cable, and then the fourth network card module 232 is connected to the network cable. When the NIC module 232 is connected to the external network, the first control module 220 has generated the shared network, and the second control module 230 has accessed the shared network, and the second control module 230 can access the external network through the fourth NIC module 232 for network communication. The second network card module 231 can also access the shared network for network communication. The second control module 230 accesses the shared network through the network expansion module 210 having the switch function, and the network expansion module 210 stores the MAC (Media Access Control) address of the control module (network card module) connected thereto, and records The interface corresponding to the MAC address, so that the data frame can be accurately forwarded; the number of IP addresses occupied by the electronic device 200 can be reduced externally; For example, when the IP address of the first control module 220 is 110.110.10.0, if the IP address of the first control module 220 is 110.110.10.0, the second control module 230 directly performs network communication through the external network. The control module 230 needs to occupy the IP address 110.110.20.0, so that the local area network cannot access other electronic devices because the IP address is insufficient; but when the second control module 230 performs network communication through the shared network, the second control module 230 may occupy the IP address. For 110.110.10.10, the LAN can be connected to an electronic device. Of course, the second control module 230 directly performs network communication through the external network to improve communication reliability and reduce network delay. The network expansion module 210 may also be a module having a routing function or a hub function, etc., which is not limited by the present invention.

As described above, the third network card module 222 and the fourth network card module 232 can both access the external network, and the first control module 220 and the second control module 230 can start the network sharing function, improve network stability and avoid based on unified management. For the purpose of function conflicts and the like, an embodiment of the present invention provides a method for unified management of configuring a network sharing function, for example, unified management by the first control module 220.

When the third network card module 222 and the fourth network card module 232 are connected to or disconnected from the external network, the third network card module 222 and the fourth network card module 232 can generate change information for notifying that the network connection has changed, and change the information to the first control module 220. A control module 220 can know that the electronic device 200 is connected to the external network, and can further determine whether to reconfigure the network sharing function or the like according to the change information. The first control module 220 and the second control module 230 can communicate via a communication bus in the electronic device 200. The first control module 220 can update the network connection status information according to the change information. For example, the first control module 220 can record the status of each module accessing the external network (including the change) through the network connection status table, and the electronic device 200 is not connected. The network connection status table when entering the external network is as shown in Table 1; the network connection status table when the first control module 220 is connected to the external network is as shown in Table 2; when the second control module 230 is connected to the external network. The network connection status table is as shown in Table 3; the network connection status table when the first control module 220 is disconnected from the external network is as shown in Table 4 below;

The network becomes unconnected to the external network.

Therefore, when only the first control module 220 accesses the external network in the updated network connection status information (network connection status table 2), the first control module 220 starts the network sharing function; when the updated network connection status information (table 4) When only the second control module 230 is connected to the external network, the first control module 220 may send a notification to initiate the network sharing function to the second control module 230, and the second control module 230 initiates the network sharing according to the startup notification information. Features. For the case where the first control module 220 and the second control module 230 shown in Table 3 are connected to the external network, reference may be made to the foregoing description, and details are not described herein. Certainly, the control module in the electronic device 200 is not limited to two, and may have any number. The manner of adding the control module to the network and sharing the network is similar; the number of interfaces of the network expansion module 210 can be set as needed, of course, Other devices that need to access the Internet can be connected to the shared network through the network extension module 210.
