It converts the format of transmitted data, while the virtual-physical interface module is used for data transmission.

[0061] Figure 4 for Figure 1 A schematic diagram of the interference source simulator for a wireless communication simulation node. (See diagram below.) Figure 4 As shown, the interference source simulator 20 is used to simulate the operation of electromagnetic interference sources such as interference sources. It mainly includes an interference source parameter configuration module, a data format conversion module, and a virtual-real interface module.

It mainly includes virtual and real interfaces, radio models, interference source models and wireless channel communication networking modules.

[0064] The virtual-physical interface connects multiple wireless communication simulation nodes 10, i.e., the first to the Nth wireless communication simulation nodes, for data transmission between the network simulation platform 30 and the wireless communication simulation nodes 10. The number of radio models is the same as the number of radio communication simulators, with a one-to-one correspondence. Parameter synchronization is performed based on the configuration parameters of the radio communication simulators. There are N radio models, denoted as Radio Model 1 to Radio Model N, and mapped to Radio Communication Simulators 1 to Radio Communication Simulator N, respectively.

[0067] Figure 6 A flowchart of a simulator-oriented network communication performance simulation method is provided for some embodiments of the present disclosure, as shown in Figure 6 Some embodiments of the present disclosure provide a simulator-oriented network communication performance simulation method, which specifically includes the following steps:

[0068] S110: Based on the parameter configuration of the interference source simulator and the plurality of radio communication simulators, the network electricity simulation platform performs initialization operation to obtain the channel quality parameter between any two radio model;

[0069] S120: Determine the first radio communication simulator and the second radio communication simulator participating in communication;

[0070] S130: Determine whether the parameters of at least one of the interference source simulator, the first radio communication simulator and the second radio communication simulator change, if yes, the network electricity simulation platform updates the channel quality parameter between the first radio model and the second radio model based on the changed parameters of the interference source simulator, the first radio communication simulator and the second radio communication simulator;

[0071] S150: The first radio communication simulator and the second radio communication simulator perform simulated communication based on the latest channel quality parameter.

[0072] In step S110, the network electricity simulation platform calculates the channel quality parameter between any two radio models based on the parameter configuration of the interference source simulator and the plurality of radio communication simulators, which is used for subsequent quantitative communication simulation.

[0073] In some embodiments, step S110 includes the following specific steps:

[0074] S111: Synchronize the parameters of the interference source simulator and the plurality of radio communication simulators to the corresponding interference source model and the plurality of radio models in the network electricity simulation platform respectively;

[0075] S112: For any two radio models, one radio model generates simulated communication data packets and sends them to the other radio model, realizing simulated communication data transmission, and the interference source model transmits interference data packets to at least one of the two radio models;

[0076] S113: During the simulated communication data transmission process, the other radio model calculates the channel quality parameter between the two radio models based on the parameters of the interference source simulator and the plurality of radio communication simulators using the electromagnetic wave propagation model.

[0077] In step S111, based on the communication between the interference source simulator and the plurality of radio communication simulators and the network electricity simulation platform, the radio communication simulator 1, the radio communication simulator 2, …, the radio communication simulator N and the interference source simulator respectively set the radio parameters, the interference parameters, form the configuration parameters, and respectively inject the configuration parameters into the corresponding radio model 1, the radio model 2, …, the radio model N and the interference source model of the network electricity simulation platform, respectively set the corresponding parameters of the models, realize the complete mapping between the radio communication simulator 1, the radio communication simulator 2, …, the radio communication simulator N and the interference source simulator and the radio model 1, the radio model 2, …, the radio model N and the interference source model.

[0078] In step S112, the network electricity simulation platform calculates the channel quality parameters between any two radio models, forms the channel quality parameters, taking the radio model 1 and the radio model 2 as an example. The radio model 1 generates a simulated communication data packet, which is irrelevant to the actual service data packet to be transmitted in the radio communication simulator 1, and is a simulated communication data packet randomly generated for calculating the channel quality parameters between the radio model 1 and the radio model 2.

[0079] The simulated communication data packet is sent to the application layer of the radio model 1 communication link, the application layer encapsulates the simulated communication data packet according to the TCP / IP protocol, records various statistical information of the simulated communication data packet, such as the number of packets, throughput, delay, etc. Then it is sent to the transport layer, which implements the UDP transport layer protocol, which is encapsulated and sent to the data link layer through the network layer, and the data link layer completes the encapsulation of the simulated communication data packet and sends it to the physical layer. The physical layer sends the encapsulated simulated communication data packet to the physical layer of the radio model 2.

[0080] The interference source model transmits interference data packets to at least one of the communication simulator model 1 and the radio model 2, and the transmission of the interference data packets is determined by the configuration parameters of the interference source model synchronized with the interference source simulator.

[0081] In step S113, the physical layer of the radio model 2 calculates the channel quality information such as the bit error rate and the signal-to-noise ratio based on the simulated communication data packet of the communication simulator model 1 and the interference data packet from the interference source model, and transmits the data packet to the data link layer of the radio model 2. The data link layer sends the data packet after removing the link layer encapsulation to the transport layer of the radio model 2 through the network layer, the transport layer removes the encapsulation and sends it to the application layer of the radio model 2, and the application layer calculates the channel quality information such as the delay, the packet loss rate and the throughput to form the channel quality parameters.

[0082] In some embodiments, in step 130, a first radio communication simulator and a second radio communication simulator participating in the communication are determined from the communication instructions among the plurality of radio communication simulators, for example, radio communication simulator 1 and radio communication simulator 2. Those skilled in the art can understand that the first radio communication simulator and the second radio communication simulator here are only exemplified by radio communication simulator 1 and radio communication simulator 2, and in other embodiments, any two of the N radio communication simulators can be selected.

[0083] In step S130, for the first radio communication simulator and the second radio communication simulator participating in the communication confirmed in step S120, it is necessary to confirm whether the configuration parameters of the two and the interference source simulator have changed, if changed, the channel quality parameters between the first radio model and the second radio model need to be recalculated, if not changed, there is no need to recalculate, and the previous channel quality parameters between the first radio model and the second radio model can be used.

[0084] In step S130, the network electrical simulation platform updates the channel quality parameters between the first radio model and the second radio model based on the changed parameters of the interference source simulator, the first radio communication simulator and the second radio communication simulator, including the following steps:

[0085] S131: Synchronize the changed parameters of the interference source simulator, the first radio communication simulator and the second radio communication simulator to the corresponding interference source model, the first radio model and the second radio model in the network electrical simulation platform respectively;

[0086] S132: The first radio model generates a simulated communication data packet and sends it to the second radio model, realizes simulated communication data transmission, and the interference source model transmits an interference data packet to at least one of the first radio model and the second radio model;

[0087] S133: During the simulated communication data transmission process, the second radio model updates and calculates the channel quality parameters between the first radio model and the second radio model based on the changed parameters of the interference source simulator, the first radio communication simulator and the second radio communication simulator, and uses the electromagnetic wave propagation model.

[0088] In step S131, based on the communication between the interference source simulator and multiple radio communication simulators and the network simulation platform, the radio communication simulator 1, radio communication simulator 2 and interference source simulator update the radio parameters and interference parameters locally to form configuration parameters, and inject the configuration parameters into the corresponding radio model 1, radio model 2 and interference source model of the network simulation platform respectively, and set the corresponding parameters of these models respectively, so as to realize the complete mapping between the radio communication simulator 1, radio communication simulator 2 and interference source simulator and the radio model 1, radio model 2 and interference source model.

[0089] In step S132, radio model 1 generates a simulated communication data packet, which is unrelated to the actual service data packet to be transmitted in radio communication simulator 1. It is a simulated communication data packet randomly generated in order to calculate the channel quality parameters between radio model 1 and radio model 2.

[0090] The simulated communication data packets are sent to the application layer of the communication link in radio model 1. The application layer encapsulates the simulated communication data packets according to the TCP / IP protocol and records various statistical information of the simulated communication data packets, such as packet count, throughput, and latency. Then it sends them to the transport layer, which implements the UDP transport layer protocol. After encapsulation, it sends the data packets to the data link layer via the network layer. The data link layer encapsulates the simulated communication data packets and sends them to the physical layer. The physical layer then sends the encapsulated simulated communication data packets to the physical layer of radio model 2.

[0091] The interference source model transmits interference data packets to at least one of the communication simulator model 1 and the radio model 2. The transmission of interference data packets is determined by the configuration parameters of the interference source model synchronizing the interference source simulator.

[0092] In step S133, the physical layer of radio station model 2 recalculates channel quality information such as bit error rate and signal-to-noise ratio based on communication data packets simulated by communication simulator model 1 and interference data packets from interference source model, and transmits the data packets to the data link layer of radio station model 2. The data link layer sends the data packets after decapsulation to the transport layer of radio station model 2 via the network layer. The transport layer decapsulates the data packets and sends them to the application layer of radio station model 2. The application layer calculates channel quality information such as delay, packet loss rate, and throughput to form updated channel quality parameters.

[0093] In some embodiments, the process of updating the channel quality parameters between the first radio station model and the second radio station model based on the changed parameters of the interference source simulator, the first radio station communication simulator, and the second radio station communication simulator further includes the following steps:

[0094] S134: The second radio station model will transmit the updated channel quality parameters between the first radio station model and the second radio station model to the first radio station model;

[0095] S135: The first radio station model and the second radio station model respectively synchronize the updated channel quality parameters between the first radio station model and the second radio station model to the first radio station communication simulator and the second radio station communication simulator.

[0096] In step S134, radio station model 2 transmits the updated channel quality parameters between radio station model 1 and radio station model 2 to radio station model 1. This ensures that both radio station model 1 and radio station model 2 obtain the channel quality parameters between them.

[0097] In step S135, radio station model 1 and second radio station model 2 synchronize the updated channel quality parameters between them to radio communication simulator 1 and radio communication simulator 2, respectively.

[0098] Whether transmitting service data packets from radio communication simulator 1 to the second radio communication simulator 2, or from radio communication simulator 2 to the second radio communication simulator 1, the channel quality parameters between radio model 1 and radio model 2 are used for processing during the communication simulation process.

[0099] In some embodiments, such as Figure 6 As shown, step S150 includes the following steps:

[0100] S151: The first radio communication simulator sends service data packets directly to the second radio communication simulator via the network;

[0101] For example, radio communication simulator 1 receives voice and / or text data from communication information generation and display device 1, generates business data packets, and transmits them to radio communication simulator 2 via a wired network, such as Ethernet.

[0102] S152: The second radio communication simulator receives the service data packet and the latest channel quality parameters from the network simulation platform, and calculates and generates voice and / or text data in a simulated electromagnetic environment based on the service data packet and the latest channel quality parameters.

[0103] For example, the radio communication simulator 2 receives the service data packet and the latest channel quality parameters from the network simulation platform, and calculates and generates voice and / or text data in a simulated electromagnetic environment based on the service data and the latest channel quality parameters, and sends it to the information generation and display device 2 to output voice or text output signals.

[0104] In some embodiments, such as Figure 6As shown, before the first radio communication simulator directly sends service data packets to the second radio communication simulator via the network, the network communication performance simulation method further includes:

[0105] S140: The first communication information generation and display device receives voice and / or text input signals, processes the voice and / or text signals to generate voice and / or text input data, and sends it to the first radio communication simulator. The first radio communication simulator generates a service data packet based on the voice and / or text input data.

[0106] Specifically, for example, the communication information generation and display device 1 receives voice and / or text input signals from the outside world, converts the voice or text input signals into voice or text input data and sends them to the radio communication simulator 1, and the service data generation module in the radio communication simulator 1 generates service data packets based on the voice and / or text input data.

[0107] In some embodiments, such as Figure 6 As shown, after the second radio communication simulator receives the service data packet and the latest channel quality parameter data from the network simulation platform, and calculates and generates voice and / or text data in the simulated electromagnetic environment based on the service data packet and the latest channel quality parameters, the network communication performance simulation method further includes the following steps:

[0108] S160: The second communication information generation and display device receives voice and / or text data in the simulated electromagnetic environment and converts the voice and / or text data in the simulated electromagnetic environment into voice and / or text output signals for output.

[0109] Specifically, for example, the communication information generation and display device 2 receives voice and / or text data in a simulated electromagnetic environment from the radio communication simulator 2, and converts the voice and / or text data in the simulated electromagnetic environment into voice and / or text output signals.

[0110] In some embodiments, such as Figure 6 As shown, prior to step S110, the network communication performance simulation method further includes:

[0111] S100: Based on the interference source simulator connected to the network electrical simulation platform and multiple radio communication simulators, and configuring the interference source model and multiple radio models on the network electrical simulation platform, the interference source model is mapped to the interference source simulator, and the multiple radio models are respectively mapped to the multiple radio communication simulators.

[0112] Specifically, the network simulation platform configures the interference source model based on the interference source simulator connected to it, and configures the radio model based on the number of radio communication simulators connected to it.

[0113] In some embodiments, the channel quality parameters include bit error rate, signal-to-noise ratio, latency, and packet loss rate.

[0114] The network communication performance simulation method for simulators provided in this disclosure eliminates the need for channel quality simulation. Since channel quality is independent of communication content, the network simulation platform only needs to run wireless communication simulations and calculate channel quality parameters when the radio communication simulator or interference source simulator is initialized or its parameters change. When the parameters of the radio communication simulator and the interference source remain unchanged, the communication channel quality parameters can always be used as the basis for communication effect simulation. Therefore, when simulating communication between radio communication simulators, communication effect simulation can be performed directly. This method eliminates the need for cumbersome real-time disassembly of channel quality parameters, improving simulation efficiency.

[0115] Figure 7 The diagram illustrates a flowchart of a network communication performance simulation method for simulators, based on some embodiments of this disclosure. Taking the simulation of radio voice communication between radio communication simulator 1 and radio communication simulator 2 as an example, the configuration parameters of radio communication simulator 1, radio communication simulator 2, and the interference source simulator have all been changed.

[0116] like Figure 7 As shown, radio communication simulator 1, radio communication simulator 2, and interference source simulator set radio parameters and interference parameters locally, forming configuration data packets respectively. The interference parameters correspond to the simulated interference environment, such as an electromagnetic environment. The configuration data packets are injected into the corresponding models of the network electrical simulation platform, namely radio model 1, radio model 2, and interference source model, respectively. The corresponding parameters of radio model 1, radio model 2, and interference source model are modified to achieve a complete mapping between radio communication simulator 1 and radio model 1, radio communication simulator 2 and radio model 2, and interference source simulator and interference source model.

[0117] The interference source model applies interference to radio station models 1 and 2 based on its parameters, for example, by sending interference data packets to them. One of radio station models 1 and 2 generates simulated communication data packets, for example, for radio station model 1, and sends these simulated communication data packets to the other of radio station models 1 and 2, for example, for radio station model 2. Radio station model 2 calculates channel quality information such as delay, packet loss rate, and throughput to obtain channel quality parameters. Radio communication simulator 2 sends the calculated channel quality information, such as bit error rate, signal-to-noise ratio, delay, and packet loss rate, to radio station models 1 and radio communication simulator 2. Radio station model 1 sends its channel quality information to radio communication simulator 1, thus synchronizing the channel quality parameters.

[0118] During the simulated voice communication phase, both wireless communication simulation nodes need to complete four stages: voice acquisition, voice transmission, communication effect simulation, and voice playback.

[0119] In the voice acquisition stage, the voice acquisition module of the communication information generation and display device 1 acquires the voice analog signal, converts it into a digital signal, and then transmits it to the radio communication simulator 1 through the audio interface.

[0120] In the voice transmission stage, the radio communication simulator 1 sends the voice data from the communication information generation and display device 1 to the radio communication simulator 2 via Ethernet.

[0121] In the communication effect simulation stage, after receiving the voice data, the radio communication simulator 2 processes the voice data according to the channel quality information to simulate the wireless communication effect under a real electromagnetic environment; and sends the processed voice data to the communication information generation and display device 2.

[0122] During the voice playback phase, the communication information generation and display device 2 receives the voice data and then plays the voice data.

[0123] This completes the voice communication simulation from wireless communication simulation node 1 to wireless communication simulation node 2. Wireless communication simulation node 2 replies to wireless communication simulation node 1, and the communication process is similar. By having these four stages work sequentially, the voice communication simulation between the two simulation nodes is achieved.

[0124] Configure the radio communication simulator and its corresponding model parameters for wireless communication simulation, and set the interference parameters and levels on the interference source simulator. After the communication information generation and display device generates simulated communication data, this data is sent from the transmitting radio communication simulator to the receiving radio communication simulator via a wired network. The receiving radio communication simulator processes the received data according to the channel communication quality parameters and displays the communication effect through the interconnected communication information generation and display device. If the generated data is voice data, the voice quality will exhibit varying degrees of interference, such as unclear intelligibility or excessive noise, thus achieving a quantitative simulation of the communication effect.
