The integrated air-ground-space network is large in scale, has many communication nodes, involves complex and changeable environments, and has highly dynamic characteristics. The deployment of the integrated air-ground-space network requires solving a large number of technical difficulties.

[0009] The message push module and parameter delivery module in the heterogeneous information adaptive matching module are used in combination with the heterogeneous information adaptive matching strategy to realize the dynamic mapping between virtual nodes and physical nodes, virtual links and physical links, and complete the mapping between the virtual communication network simulation scenario and the physical physical communication network.

[0010] In a further embodiment, the configuration process of the heterogeneous probe monitoring device is as follows:

[0011] The non-intrusive probe is divided into a collector, a transmitter and a collector. The collector sends the collected information to the collector through the transmitter on the application side. The collector is deployed in the nodes and links in the physical communication network. The information collected on the collector has unique identification. Different collectors are set to form the required heterogeneous probe monitoring device.

[0012] Among them, the heterogeneous probe monitoring device includes at least: a node statistics probe for monitoring the number of nodes in the communication network, a node status probe for monitoring the operating status of the node, a node indicator probe for monitoring communication node indicators, and a link status probe for monitoring the link operating status.

[0017] If the collected data is large-volume data, packet loss processing is performed on the corresponding data according to demand; the indicator item of the large-volume data is constellation diagram information.

[0018] In a further embodiment, the workflow of the message push module is as follows:

[0019] The messages reported by heterogeneous probe monitoring devices are uniformly converted into JSON format, and different physical nodes or physical links are separated and parsed according to the JSON parsing method;

[0046] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0047] Example 1

[0048] This embodiment discloses a virtual-reality mapping method for an air-ground integrated network, comprising the following steps:

[0049] Configure a heterogeneous probe monitoring device to obtain the real-time operating status of each physical node and physical link in the physical physical communication network; determine whether the status of the physical node and / or physical link is normal based on the operating status: if it is determined to be normal, perform signaling detection; if it is determined to be abnormal, perform abnormal status processing;

[0050] Combination Figure 2 ,The working process of the heterogeneous probe monitoring device is as follows: according to the ,instructions of signaling detection, corresponding data is acquired in combination with ,adaptive acquisition strategy to obtain message data, and the message data is ,reported to the heterogeneous information adaptive matching ,module;

[0051] The message push module and parameter delivery module in the heterogeneous information adaptive matching module are used in combination with the heterogeneous information adaptive matching strategy to realize the dynamic mapping between virtual nodes and physical nodes, virtual links and physical links, and complete the mapping between the virtual communication network simulation scenario and the physical physical communication network.

[0052] In this implementation, the role of the heterogeneous probe monitoring device is to meet the needs of adaptive monitoring and collect information of different granularities. Therefore, Java probe technology is used to set probes with different attributes. The configuration process of the heterogeneous probe monitoring device is as follows:

[0053] The non-intrusive probe is divided into a collector, a transmitter and a collector. The collector sends the collected information to the collector through the transmitter on the application side. The collector is deployed in the nodes and links in the physical communication network. The information collected on the collector has unique identification. Different collectors are set to form the required heterogeneous probe monitoring device.

[0054] The heterogeneous probe monitoring device includes at least: a node statistics probe for monitoring the number of nodes in the communication network, a node status probe for monitoring the running status of the node, a node indicator probe for monitoring the communication node indicator, and a link status probe for monitoring the link running status. The information collected by different collectors is sent to the collector through the transmitter of the application layer. Finally, the collector stores it according to different information representations. The structure is as follows Figure 1 shown.

[0055] Based on the above description, when the probe monitoring service is initiated, the status of each node and link is continuously obtained through the node statistics probe, node status probe and link status probe. Therefore, the real-time operation status includes active state and static state. If the current real-time operation status is active, the status of the node and / or link is judged to be normal; conversely, if the current real-time operation status is static, the status of the node and / or link is judged to be abnormal.

[0056] In other words, the active state means that the node is running normally, and the dormant state means that the node is stopped. If the status of each node and link is normal, signaling detection is performed. If the status of a node or link is abnormal, abnormal status processing is performed.

[0057] In another embodiment, when the parameter data is reported, in order to ensure that various probes can efficiently and adaptively collect data and indicators according to the comprehensive status of the physical communication network and the high-speed network status, the specific performance of the heterogeneous information adaptive matching strategy is as follows:

[0058] First, since the communication indicators include indicators with less data volume, such as signal-to-noise ratio, bit error rate, channel state information, etc., the corresponding indicators are collected at a fixed frequency, and the collection frequency is adjusted adaptively according to the load state of the high-speed network. Another type of indicator, such as constellation information, has a large amount of data volume. Considering that not all data in the constellation information is necessary, in order to ensure real-time performance, when the load of the high-speed network is high or the constellation data volume is too large, the data can be appropriately dropped. For example, only the odd number of data in the original data is sent, such as sending the 1st, 3rd, 5th... data, and discarding the 2nd, 4th, 6th... data.

[0059] In a further embodiment, the heterogeneous information adaptive matching module includes a message pushing module and a parameter sending module.

[0060] Corresponding, combined Figure 3 The workflow of the message push module is as follows:

[0061] The messages reported by heterogeneous probe monitoring devices are uniformly converted into JSON format, and different physical nodes or physical links are separated and parsed according to the JSON parsing method;

[0062] Encapsulate the virtual node or virtual link ID and the message to be distributed according to a predetermined message encapsulation format;

[0063] The virtual device matches information according to the adaptive matching strategy and pushes information using websocket push or MQ push according to different communication demand types;

[0064] The message encapsulation format is expressed in the following form: node or link type-ID-data, and its structure is expressed as follows: Figure 4 shown.

[0065] In another embodiment, in combination Figure 5 The parameter delivery module workflow is as follows:

[0066] Receive the virtual parameters of the virtual node or virtual link, the parameters including: virtual node type and virtual node ID, virtual link type and virtual link ID;

[0067] The parameters are stored in JSON format, and different virtual node or virtual link information is separated and parsed according to the JSON parsing method;

[0068] The virtual node or virtual link information is encapsulated according to the predetermined parameter information format, and the virtual device matches the information according to the adaptive matching strategy, and sends it using websocket push or MQ push according to different communication demand types;

[0069] The parameter information format is expressed in the following form: virtual node or virtual link type-ID-parameter, and its structure is expressed as follows: Figure 6 shown.

[0070] It should be noted that the specifics of the adaptive matching strategy for heterogeneous information are as follows:

[0071] In the virtual communication network simulation scenario, the information from the node and the information from the link are collectively referred to as heterogeneous information. The information from the node is the unique identifier of the virtual node: the virtual node type and the virtual node ID; the information from the link is the unique identifier of the virtual link: the virtual link type and the virtual link ID;

[0072] Based on the type and ID of the physical node, the type and ID of the physical link, the heterogeneous information is compared one by one to obtain the corresponding virtual device.

[0073] In other words, the virtual communication network simulation scenario consists of virtual nodes and virtual links. The node type and ID, link type and ID serve as the unique identifiers of virtual nodes and virtual links, and serve as the basis for dynamic mapping and binding between virtual nodes and physical nodes, and virtual links and physical links.

[0077] The heterogeneous information adaptive matching module includes: a message push module and a parameter delivery module;

[0078] The virtual communication network simulation scenario includes a plurality of virtual devices, and virtual links and virtual nodes formed by the virtual devices.

[0079] In other words, virtual nodes and virtual links can be described by computer files and computer devices.
