[0002] In related technologies, network video recorders (VVRs) can establish network communication connections with multiple network cameras. Different network cameras have different network addresses, so after replacing a network camera, the network address configuration of the VVR needs to be manually modified accordingly. However, when many network cameras are replaced, manually modifying the network address configuration becomes overly cumbersome, thus affecting the efficiency of establishing network communication connections between the VVR and the network cameras. Therefore, how to provide a communication connection method to improve the efficiency of establishing network communication connections between VVRs and network cameras has become an urgent technical problem to be solved. Summary of the Invention

To this end, this invention proposes a communication connection method that can improve the efficiency of establishing a network communication connection between a network video recorder and a network camera.

[0063] In related technologies, network video recorders (VVRs) can establish network communication connections with multiple network cameras. Different network cameras have different network addresses, so after replacing a network camera, the network address configuration of the VVR needs to be manually modified accordingly. However, when many network cameras are replaced, manually modifying the network address configuration becomes overly cumbersome, thus affecting the efficiency of establishing network communication connections between the VVR and the network cameras. Therefore, how to provide a communication connection method to improve the efficiency of establishing network communication connections between VVRs and network cameras has become an urgent technical problem to be solved.

[0064] Based on this, embodiments of the present invention provide a communication connection method, apparatus, communication system, device, medium, and product, which can improve the efficiency of establishing a network communication connection between a network video recorder and a network camera.

[0065] It should be noted that in the following embodiments, a network video recorder is used as the preset communication device, and a network camera is used as the target communication device for illustrative purposes. However, it should be understood that other types of network communication devices should also fall within the protection scope of the embodiments of this invention.

[0066] like Figure 1 As shown, this embodiment of the invention provides a communication connection method, which is applied to a preset communication device, and the preset communication device establishes a communication connection with a target communication device. This communication connection method includes, but is not limited to, steps S110 to S160, which will be described in detail below.

[0067] Step S110: Obtain the target network address of the target communication device;

[0068] Step S120: Perform a network segment determination operation based on the preset network address and the target network address to obtain the network segment determination result; wherein, the preset network address is the network address of the preset communication device;

[0069] Step S130: If the network segment judgment result indicates that the network segments between the preset network address and the target network address are different, filter the preset virtual network card according to the target network address to obtain the network card filtering result;

[0070] Step S140: If the network card filtering result indicates that the network address of the preset virtual network card is different from the target network address, perform a connection test operation on the target communication device according to the preset connection test module to obtain the first connection test result;

[0071] Step S150: If the first connection test result indicates that the connection test module fails to connect with the target communication device, create a first target virtual network card based on the target network address; wherein, the network address of the first target virtual network card is the target network address;

[0072] Step S160: Establish a communication connection between the first target virtual network card and the target communication device.

[0073] According to the communication connection method of this embodiment, by acquiring a preset network address and a target network address, it is determined whether a preset communication device can directly establish a network communication connection with a target communication device. If a direct connection is not possible, a preset virtual network interface card (NIC) is filtered based on the target network address to search for a NIC that matches the target network address. If no matching NIC exists, a connection test is performed on the target communication device using a preset connection test module to determine whether the target communication device is in the upstream network of the local area network of the preset communication device. If the target communication device is not in the upstream network, a first target virtual NIC is created based on the target network address, and a communication connection is established between the preset communication device and the target communication device using the first target virtual NIC. This communication connection method enables the preset communication device and the target communication device to quickly establish a network communication connection, thereby improving the efficiency of establishing a network communication connection between a network video recorder and a network camera.

[0074] In step S110 of some embodiments, the preset communication device and the target communication device can establish a physical connection in advance via a connection method such as a network cable connection. The target network address includes the IP address and subnet mask of the target communication device. For example, the obtained target network address may have an IP address of 192.168.1.20 and a subnet mask of 255.255.255.0.

[0075] In step S120 of some embodiments, the preset network address includes the IP address and subnet mask of the preset communication device. For example, the IP address of the obtained preset network address can be 192.168.1.10 and the subnet mask can be 255.255.255.0.

[0076] After obtaining the preset network address and the target network address, it is determined whether the network segment of the preset network address and the network segment of the target network address are the same, thus obtaining the network segment determination result. This can be achieved by performing a bitwise AND operation on the IP address and subnet mask of the network address to obtain the network segment addresses of the preset network address and the target network address, respectively, for network segment determination. For example, if the IP address of the preset network address is 192.168.1.10 and the subnet mask is 255.255.255.0, performing a bitwise AND operation on the IP address and subnet mask yields the network segment address 192.168.1.0. Similarly, if the IP address of the target network address is 192.168.2.30 and the subnet mask is 255.255.255.0, performing a bitwise AND operation on the IP address and subnet mask yields the network segment address 192.168.2.0. As can be seen, the network segment address 192.168.1.0 of the preset network address is different from the network segment address 192.168.2.0 of the target network address. The network segment determination result at this point indicates that the network segments of the preset and target networks are not the same. When the network segments of the preset and target networks are the same, it means that the network address of the physical network card of the preset communication device matches the network address of the target communication device. In this case, the preset communication device can directly establish a network communication connection with the target communication device using its physical network card.

[0077] In step S130 of some embodiments, when the network segment of the preset network address is different from the network segment of the target network address, it indicates that the network address of the physical network card of the preset communication device does not match the network address of the target communication device, and the preset communication device cannot establish a network communication connection with the target communication device using the physical network card. At this time, the preset virtual network cards pre-configured in the preset communication device are filtered using the target network address to determine whether the network address of the preset virtual network card is the same as the target network address, thereby obtaining the network card filtering result.

[0078] The preset communication device can be pre-configured with multiple preset virtual network cards. When the network address of any preset virtual network card is the same as the target network address, the network card filtering result is obtained, indicating that the network address of the preset virtual network card is the same as the target network address. When the network addresses of all preset virtual network cards are different from the target network address, the network card filtering result is obtained, indicating that the network address of the preset virtual network card is different from the target network address.

[0079] like Figure 4 As shown, in some embodiments of the present invention, the communication connection method further includes, but is not limited to, steps S210 and S220, which will be described in detail below.

[0080] Step S210: If the network card filtering result indicates that the network address of the preset virtual network card is the same as the target network address, the preset virtual network card with the same network address as the target network address is used as the second target virtual network card;

[0081] Step S220: Establish a communication connection between the preset communication device and the target communication device based on the second target virtual network card.

[0082] In step S210 of some embodiments, when the network card filtering result indicates that the network address of the preset virtual network card is the same as the target network address, it indicates that the network address of the preset virtual network card matches the network address of the target communication device. At this time, the preset virtual network card is used as the second target virtual network card.

[0083] In step S220 of some embodiments, after determining the second target virtual network card, since the network address of the second target virtual network card is in the same network segment as the target network address of the target communication device, the preset communication device can establish a communication connection with the target communication device based on the second target virtual network card.

[0084] In step S140 of some embodiments, when the network card screening result indicates that the network address of the preset virtual network card is different from the target network address, it means that the network address of the preset virtual network card does not match the network address of the target communication device, and the preset communication device cannot establish a communication connection with the target communication device using the preset virtual network card. At this time, the connection test module of the preset communication device is used to perform a connection test on the target communication device to determine whether the target communication device is in the same local area network as the preset communication device and its parent network, thereby obtaining the first connection test result.

[0085] The connection test module can create a socket based on the target network address and port number of the target communication device, and then use this socket to attempt a network connection with the target communication device. When the first connection test result shows that the connection test module has successfully connected with the target communication device, it indicates that the target communication device's network address is in the same upstream network as the preset communication device on the same local area network. At this point, it is not necessary to create a new virtual network card. Instead, the preset communication device sends a connection request to the gateway, and the gateway establishes a communication connection between the preset communication device and the target communication device based on the connection request.

[0086] In step S150 of some embodiments, when the first connection test result indicates that the connection test module fails to connect with the target communication device, it indicates that the target communication device is not in the upstream network of the preset communication device and cannot be connected via the gateway. At this time, a first target virtual network interface card (NIC) is created in the same network segment as the target network address. This first target virtual NIC can be created using system control commands of the preset communication device. For example, the system command "ifconfig eth0:2192.168.2.10" can be used to create the first target virtual NIC, where "eth0" is the name of the physical NIC on which the first target virtual NIC resides, "eth0:2" is the name of the first target virtual NIC, and "192.168.2.10" is the network address of the first target virtual NIC.

[0087] In step S160 of some embodiments, after the first target virtual network card is created, since the network address of the first target virtual network card is in the same network segment as the target network address of the target communication device, the preset communication device can establish a communication connection with the target communication device based on the first target virtual network card.

[0088] like Figure 3 As shown, in some embodiments of the present invention, step S160 includes, but is not limited to, steps S310 and S320, which will be described in detail below.

[0089] Step S310: Perform a connection test operation between the first target virtual network card and the target communication device according to the connection test module, and obtain the second connection test result;

[0090] Step S320: Establish a communication connection with the target communication device based on the results of the second connection test.

[0091] In step S310 of some embodiments, after creating the first target virtual network interface card (NIC), a connection test module is used to test whether the first target virtual NIC can connect to the target communication device, thereby obtaining a second connection test result. The connection test module creates a socket based on the target network address and port number of the target communication device, and uses the socket to attempt to establish a network connection between the first target virtual NIC and the target communication device.

[0092] In step S320 of some embodiments, after obtaining the second connection test result, a communication connection between the preset communication device and the target communication device can be established using the first target virtual network card based on the second connection test result.

[0093] The following is a detailed description of step S320. For example... Figure 4 As shown, in some embodiments of the present invention, step S320 includes, but is not limited to, steps S410 and S420, which will be described in detail below.

[0094] Step S410: If the second connection test result indicates that the first target virtual network card and the target communication device are successfully connected, establish a communication connection between the first target virtual network card and the target communication device;

[0095] Step S420: If the second connection test result indicates that the first target virtual network card failed to connect with the target communication device, uninstall the first target virtual network card and generate a connection failure message.

[0096] In step S410 of some embodiments, when the second connection test result indicates that the first target virtual network card and the target communication device are successfully connected, it means that the network address of the first target virtual network card and the target network address of the target communication device are matched in terms of network segment. The preset communication device establishes a communication connection with the target communication device based on the first target virtual network card. For example, if the network address of the first target virtual network card is 192.168.2.10 and the IP address of the target network address is 192.168.2.30, it can be seen that the network segment of both the first target virtual network card and the target communication device is "192.168.2.0". At this time, the preset communication device can establish a communication connection with the target communication device based on the first target virtual network card.

[0097] In step S420 of some embodiments, when the second connection test result indicates that the connection between the first target virtual network card and the target communication device has failed, since factors such as network segment mismatch and the target communication device's network address possibly being in the upstream network of the preset communication device have been ruled out, this indicates that the target communication device required by the preset communication device does not exist, and therefore a network connection cannot be established. At this time, a connection failure message is generated to indicate that the target communication device does not exist.

[0098] like Figure 5 As shown, in some embodiments of the present invention, the target communication device that needs to be disconnected is designated as the device to be uninstalled, the target communication device that does not need to be disconnected is designated as the standby device, the target network address of the device to be uninstalled is designated as the network address to be uninstalled, the target network address of the standby device is designated as the standby network address, and a preset virtual network card with the same network address as the device to be uninstalled is designated as the network card to be uninstalled. The communication connection method further includes disconnecting the communication connection between the device to be uninstalled and the preset communication device according to the uninstallation device instruction, specifically including but not limited to steps S510 to S540, which are described in detail below.

[0099] Step S510: Detect the connection status between the device to be uninstalled and the preset virtual network card according to the uninstallation device command;

[0100] Step S520: If the connection status indicates that the device to be uninstalled is connected to the preset virtual network card, obtain the network address to be uninstalled;

[0101] Step S530: Perform a filtering operation on the devices to be uninstalled based on the network address to obtain the device filtering results;

[0102] Step S540: If the device screening result indicates that the standby network address is different from the network address to be uninstalled, uninstall the network card to be uninstalled to disconnect the communication connection between the device to be uninstalled and the preset communication device.

[0103] In step S510 of some embodiments, the uninstallation device command can be obtained manually via a touch device such as a keyboard and mouse. After obtaining the uninstallation device command, it is detected whether there is a communication connection between the device to be uninstalled and the preset virtual network card, thereby determining whether the device to be uninstalled is already in the uninstallation state. When it is detected that there is no communication connection between the device to be uninstalled and the preset virtual network card, the physical connection between the device to be uninstalled and the preset communication device can be directly disconnected.

[0104] In step S520 of some embodiments, when it is detected that the device to be uninstalled is still in a communication connection with the preset virtual network card, the network address of the device to be uninstalled is obtained.

[0105] In step S530 of some embodiments, after obtaining the network address to be uninstalled, the network address to be uninstalled is compared with the target network address of the standby device to determine whether there is a standby device with the same target network address as the network address to be uninstalled, thereby obtaining a device filtering result. If the obtained device filtering result indicates that the standby network address is the same as the network address to be uninstalled, that is, there is a standby device with the same target network address as the network address to be uninstalled, it indicates that the preset virtual network card is still being used to communicate with the standby device, and it is not necessary to uninstall the preset virtual network card.

[0106] In step S540 of some embodiments, if the obtained device filtering result indicates that the standby network address and the network address to be uninstalled are different, that is, there is no standby device with the same target network address as the network address to be uninstalled, it indicates that the preset virtual network card is already in an idle state. At this time, the preset virtual network card with the same network address as the device to be uninstalled is designated as the network card to be uninstalled, and the network card to be uninstalled is uninstalled, thereby disconnecting the communication connection between the device to be uninstalled and the preset communication device.

[0107] In one specific embodiment of the present invention, Figure 6 This is a flowchart of the communication connection method. Each step in the flowchart has been described in detail in the above embodiments. For details, please refer to the description of each step in the above embodiments.

[0108] This invention also provides a communication system comprising: a switch, a target communication device, and a preset communication device.

The preset communication device is used to obtain a target network address through the switch, and to execute the communication connection method as described in any of the above embodiments based on the target network address.

[0109] Specifically, the switch can establish electrical connections between the pre-set communication devices and the target communication devices through connection methods such as network cable connections, and the switch can assist in data transmission between the pre-set communication devices and the target communication devices.

[0110] It is evident that the content of the above communication connection method embodiments is applicable to this communication system embodiment. The specific functions implemented in this communication system embodiment are the same as those in the above communication connection method embodiments, and the beneficial effects achieved are also the same as those achieved in the above communication connection method embodiments.
