[0002] In recent years, communication technology has developed rapidly. We have already used 5G and are researching 6G. In cities with well-developed communication infrastructure, we can enjoy the high reliability, low latency, and large bandwidth communication benefits brought to us by communication resources. However, in the event of natural disasters and other conditions, communication means mainly rely on emergency mobile communications. However, because emergency mobile communications are temporary, their resources are relatively limited. When deploying emergency communication networks on a large scale, there is an application scenario where relay communication nodes are added to ensure long-distance communication needs. Emergency mobile communications are hereinafter referred to as mobile communications.

[0003] In mobile communication networks, relay communication nodes have data transfer transmission in two or more directions. The communication switching equipment inside the relay communication nodes needs to address the data when forwarding the data. There is a risk of increased transmission time when the communication switching equipment is in queuing or calculation status.

[0028] In order to make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the technical scheme in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application. The functional units with the same labels in the examples of the present invention have the same and similar structures and functions.

[0029] See also Figure 1 The present invention provides a method for constructing a network fast channel based on a communication node, comprising:

[0030] S1. The communication service periodically sends a request to the communication switching device to query the interface connection status;

[0031] S2. The communication service determines whether to issue an instruction to start the fast channel processing module to the communication switching device according to the connection status. If the communication switching device has a bidirectional interface connection, the instruction is issued; otherwise, no response is made.

[0032] S3. The communication switching device performs bidirectional direct forwarding of data through the fast channel processing module, and the fast channel processing module completely mirrors the forwarded data to the management interface connected to the communication service.

[0033] See also Figure 2 In this embodiment, based on the fact that at least two or more communication nodes are connected in the mobile communication network and there are only communication tasks in two directions, some relay communication nodes can realize efficient direct data forwarding transmission, avoiding the need for the communication switching equipment inside the relay communication node to address the data when forwarding the data, the risk of increased transmission time when the communication switching equipment is queuing or calculating, and the risk of abnormal data loss when the communication switching equipment is congested or has logical failures.

[0034] Specifically, the communication node includes a communication transmission device, a communication switching device and a communication service device. Inside the communication node, the communication transmission device is connected to the communication switching device via a service interface, and the communication service is connected to the communication switching device via a management interface. The service interface of the communication switching device can collect and identify the interface type of the communication transmission device to which the current service interface is connected by exchanging information with the communication transmission device. The communication switching device includes a routing module, a fast channel processing module and a communication service proxy module.

[0035] See also Figure 3 The communication service agent module sends the physical interface status of the communication switching device to the communication service, receives the startup and shutdown instructions of the fast channel, and turns on or off the fast channel processing module; the physical interface status includes the interface number, interface type, physical connection status, and connection device type.

[0036] The fast channel processing module directly transmits the data received by the communication switching device interface to the designated interface, and mirrors the data to the management interface for sending out; in this mode, the communication switching device directly transparently forwards the communication data of the two connected interfaces, and when the forwarding data is completed, a copy of the data is mirrored to the management interface, and the management interface is connected to the communication service.

[0037] The routing module updates and maintains the routing table of the communication switching device, and processes and forwards the data according to the routing table; the routing module can perform routing based on a distributed routing protocol or a software defined network protocol.

[0038] In the fast channel construction mode, the communication switching device will not identify the data of the two physical interfaces in the fast channel construction mode of the communication switching device and directly forward it, but will identify and process the service data of the management port.

[0039] See also Figure 4 The communication service includes a business application module, a fast channel management module and an interactive agent module.

[0040] The business application module monitors the interface connection status of the communication switching equipment, and collects the device core IP, interface IP and dedicated management IP of the communication switching equipment, wherein the dedicated management IP is the dedicated information processing IP of the communication switching equipment, and the dedicated management IP is the static configuration of the communication switching equipment. When it is collected that the communication switching equipment has more than two interfaces for business communication, the fast channel management module will be displayed with a prompt or the constructed fast channel will be closed according to the rules.

[0041] The fast channel management module sends fast channel construction or closing instructions to the communication switching device; the fast channel to the control module sends fast channel control instructions to the communication switching device through the management port of the communication switching device. The fast channel management module can control the construction and closing of the fast channel by manually clicking on the user interface, and can also use a data condition model to achieve automatic opening control.

[0042] The interactive proxy module monitors and analyzes the mirror data forwarded by the communication switching device, identifies the data whose destination address is the managed communication switching device, and sends the data to the communication switching device through the management port connected to the communication switching device. The identification method mainly identifies whether the destination IP of the message is the device core IP of the communication switching device, the interface IP of the communication switching device, and the dedicated management IP. If any one of them is matched, the match is successful, and the successfully matched data is sent to the communication switching device through the management port connected to the communication switching device.

[0043] The reason for using an interactive proxy is that after the communication switching device turns on the fast channel construction mode, the communication switching device directly transparently forwards the data of the interface without identifying the data, resulting in the loss of some control and interactive messages sent to the communication switching device. Therefore, the transparently transmitted data is mirrored to the communication service, which is identified by the communication service and forwarded to the communication switching device through the management port. The communication switching device identifies the messages of the management port and can complete the information interaction between the communication switching device and other network equipment and service software of the mobile communication network in the fast channel construction mode.

[0044] In the present invention, the communication service periodically queries the communication switching device for information, and the queried information includes the core IP of the communication switching device, the device fault status, and the physical interface status of all interfaces, wherein the physical interface status includes the interface number, interface type, physical connection status, and connection device type;

[0045] The communication service identifies the connection status of the communication switching device and sends a fast channel construction instruction or a fast channel closing instruction to the communication switching device. The instruction may be sent manually or automatically according to the rules by the communication service.

[0046] After the communication switching device receives the fast channel construction instruction issued by the communication service, the communication switching device performs bidirectional direct forwarding of network data at both ends of the fast channel;

[0047] When the communication service finds that the communication switching device has business data transmitted on interfaces other than the through interfaces, a fast channel closing instruction is manually or automatically triggered. The through interfaces refer to interfaces at both ends of the fast channel.

[0048] The communication service monitors the data mirrored by the communication switching device. The monitoring method is to capture the network messages of the network card of the operating system where the communication service is located. The communication service checks the destination address in the data and matches it with the IP of the directly connected communication switching device. The communication service sends the matching network data to the communication switching device through the management port directly connected to the communication switching device. The matching consistency means that the destination address is the same as the IP address set by the interface IP, device IP, management IP, etc. of the communication switching device. The communication switching device processes the data information forwarded by the communication service and responds according to the content of the data information. The data information includes control information of the communication switching device, test information of the communication switching device, query information of the communication switching device, etc.
