[0026] Figure 1 A schematic diagram of the structure of a communication system provided in an embodiment of the present application.

[0027] At present, the low-orbit satellite narrowband communication test method can only test the measured data such as the voice quality of the narrowband communication terminal, and lacks the test of the data transmission status.

[0028] To address this problem, an embodiment of the present application provides a communication system to implement quality testing and status analysis of a data transmission process. The terminal involved in the embodiment of the present application is a narrowband terminal, such as Figure 1 As shown, the communication system includes: a satellite, a communication terminal, and a test platform.

[0029] The communication terminal is used to communicate with the satellite and obtain target data in the communication state, and the target data includes terminal status data and signal quality data.

[0030] Optionally, the communication terminal is a terminal device to be detected, which may include a mobile phone, a tablet computer, a computer with wireless transceiver function, a wearable device, an Internet of Things device, a car with communication function, an aircraft, a virtual reality (VR) terminal device, an augmented reality (AR) terminal device, a wireless terminal device in industrial control, a wireless terminal device in self-driving, a wireless terminal device in remote medical surgery, a wireless terminal device in a smart grid, a wireless terminal device in transportation safety, a wireless terminal device in a smart city, and at least one of a wireless terminal device in a smart home, but is not limited to these.

[0031] In an embodiment of the present application, the communication terminal and the satellite transmit data via an antenna. During the data transmission process, the communication terminal collects target data reflecting the communication status of the communication terminal, including terminal status data and signal quality data, and sends it to the test platform through a transmission interface.

[0032] Among them, the transmission interface can be a Universal Serial Bus (USB) interface, a wireless network (WIFI) interface, a Bluetooth interface, etc. In some embodiments, the USB interface is used for function debugging, the WIFI interface is used for business data transmission, and the Bluetooth interface is used for voice business transmission.

[0033] The satellite is used to send satellite downlink signals to the test platform.

[0034] Optionally, the satellite transmits data with the communication terminal on the one hand, and sends a satellite downlink signal to the test platform on the other hand, so as to test the satellite communication process from multiple aspects.

[0035] The test platform is used to receive satellite downlink signals, and perform spectrum and bandwidth analysis on the satellite downlink signals to obtain analysis results.

[0036] Optionally, the test platform receives satellite downlink signals through directional antennas. There may be differences between satellite downlink signals and ground communication signals. By performing spectrum and bandwidth analysis on the satellite downlink signals, the quality of communication data during signal transmission between the communication terminal and the satellite can be tested from the aspect of signal distribution.

[0037] The test platform is also used to receive target data from the communication terminal, obtain communication test data between the communication terminal and the satellite, and display at least one of the analysis results, communication test data and target data.

[0038] Optionally, during data transmission between the communication terminal and the satellite, the test platform obtains communication test data reflecting the data transmission quality between the communication terminal and the satellite.

[0039] Optionally, the test platform can store spectrum and bandwidth analysis results of satellite downlink signals, target data, and communication test data, and display them based on actual needs.

[0040] As a possible implementation, the test platform may read at least one of the analysis results, target data, and communication test data of a historical period for display.

[0041] As another possible implementation, the test platform may display at least one of the analysis results, target data, and communication test data acquired in real time.

[0042] In this embodiment, the communication system includes: a satellite, a communication terminal, and a test platform, wherein the communication terminal is used to communicate with the satellite and obtain target data in the communication state, and the target data includes terminal state data and signal quality data; the satellite is used to send a satellite downlink signal to the test platform; the test platform is used to receive the satellite downlink signal, and perform spectrum and bandwidth analysis on the satellite downlink signal to obtain analysis results; the test platform is also used to receive target data from the communication terminal, obtain communication test data between the communication terminal and the satellite, and display at least one of the analysis results, communication test data, and target data. The problem of lack of communication testing between the communication terminal and the satellite is solved, the data transmission process between the communication terminal and the satellite can be tested, and spectrum and bandwidth analysis can be performed simultaneously, the data transmission quality can be tested in many aspects, accurate test results can be obtained, and the communication status between the communication terminal and the satellite can be intuitively displayed.

[0043] In order to clearly explain the previous embodiment, this embodiment provides another communication system. Figure 2 A schematic diagram of the structure of another communication system provided by an embodiment of the present invention.

[0044] like Figure 2 As shown, the communication system includes a satellite, a communication terminal, and a test platform.

[0045] The communication terminal is used to communicate with the satellite and obtain target data in the communication state, and the target data includes terminal state data and signal quality data.

[0046] It should be noted that the communication terminal is used for satellite testing of narrowband communication services, including voice and data transmission service testing. As a possible implementation method, the narrowband communication terminal is composed of a communication module, an application module, and a four-arm helical antenna.

[0047] In the embodiment of the present application, the terminal status data includes the power-on status, network access status, connection status, and subscriber identity module (SIM) card status of the communication terminal; the signal quality data includes the signal-to-noise ratio and the signal level strength.

[0048] The communication terminal is also used to perform protocol encapsulation on the target data to obtain encapsulated data.

[0049] Alternatively, if Figure 3 As shown, the communication terminal encapsulates the collected target data into a data packet through a protocol, and transmits it to the test platform using the transmission interface of the communication terminal.

[0050] The test platform is also used to receive encapsulated data, perform protocol conversion on the encapsulated data, and obtain target data.

[0051] Alternatively, if Figure 3 As shown, after the test platform receives the data packet, it parses the data packet through protocol conversion, and the parsed target data can enter the test platform for data display.

[0052] The test platform is used to receive satellite downlink signals, and perform spectrum and bandwidth analysis on the satellite downlink signals to obtain analysis results.

[0053] In an embodiment of the present application, a spectrum scanning analysis is performed on the collected satellite downlink signal to obtain a spectrum diagram of the satellite downlink signal, and the difference between the spectrum diagram of the satellite downlink signal and a reference spectrum diagram is determined by comparing the spectrum diagram of the satellite downlink signal with the reference spectrum diagram.

[0054] For example, the spectrum graph analysis can be performed by analyzing the shape, peak value, frequency component and other characteristics of the spectrum graph, and then calculating the difference between the characteristic value of the spectrum graph of the satellite downlink signal and the characteristic value of the reference spectrum graph as the first signal difference.

[0055] In other embodiments, the difference between the two can be obtained by comparing the spectrum graph of the satellite downlink signal with the spectrum graph of the ground communication signal, for example, calculating the difference between the characteristic value of the spectrum graph of the satellite downlink signal and the characteristic value of the spectrum graph of the ground communication signal as the first signal difference.

[0056] In spectrum analysis, the resolution bandwidth is defined as the frequency span of the final filter applied to the input signal. The difference between the bandwidth value of the spectrum graph of the satellite downlink signal and the reference bandwidth value is calculated as the second signal difference.

[0057] In other embodiments, the difference between the bandwidth value of the spectrum diagram of the satellite downlink signal and the bandwidth value of the spectrum diagram of the terrestrial communication signal may be calculated as the second signal difference.

[0058] In the embodiment of the present application, the first signal difference and the second signal difference can reflect the communication status between the communication terminal and the satellite in terms of signal distribution. The first signal difference and the second signal difference can be evaluated by a preset threshold to obtain spectrum and bandwidth analysis results.

[0059] For example, if the first signal difference is greater than a preset threshold value of the spectrum characteristic, it means that the first signal difference is large, and when the communication terminal transmits data with the satellite, the communication data quality is poor.

[0060] Further, such as Figure 4 As shown, the test platform 4000 includes the following modules: a data playback module 4100 and a three-dimensional dynamic module 4200 .

[0061] The data playback module 4100 is used to store the communication test data into the database.

[0062] Optionally, after data processing, the rate and delay data obtained by the test platform returns the maximum rate, real-time rate, maximum delay, minimum delay, and average delay to the database for storage, so that the communication test data of the specified time period can be read from the database through the data service program and data playback, data charting, and historical data comparison can be performed.

[0063] Furthermore, the maximum rate, real-time rate, maximum delay, minimum delay, and average delay may be returned to the data playback module 4100 for real-time dynamic display of data.

[0064] The data playback module 4100 is also used to read and display at least one of the analysis results, communication test data and target data of the historical period.

[0065] Optionally, when it is necessary to retrieve data of a specified historical period for playback, the data playback module 4100 may read at least one of the analysis results, communication test data and target data of the corresponding historical period from the database for display.

[0066] The three-dimensional dynamic module 4200 is used to dynamically display the satellite communication process.

[0067] Furthermore, the three-dimensional dynamic module 4200 includes: a satellite orbit algorithm submodule 4210 , a satellite display submodule 4220 and a communication display submodule 4230 .

[0068] The satellite orbit algorithm submodule 4210 is used to generate satellite orbit data for a specified time period based on the two-planetary ephemeris text files of the satellite.

[0069] In the embodiment of the present application, the satellite orbit algorithm submodule 4210 reads the satellite ephemeris text files and generates satellite orbit data for a specified time period through a satellite orbit algorithm.

[0070] The satellite display submodule 4220 is used to display the satellite orbit, satellite model and three-dimensional earth of the satellite based on the satellite orbit data.

[0071] In the embodiments of the present application, Figure 5As shown, the satellite orbit algorithm submodule 4210 in the three-dimensional dynamic module 4200 performs data processing, data format conversion and algorithm calculation, and the satellite display submodule 4220 performs three-dimensional visual dynamic display. Specifically, when the test platform is running, the satellite orbit algorithm submodule 4210 reads the two satellite ephemeris text files, calls the satellite orbit algorithm to generate satellite orbit data for a specified time period, and then converts the orbit data into a dynamic data format and sends it to the satellite display submodule 4220. After receiving the dynamic data format, the satellite display submodule 4220 loads it into the three-dimensional map framework and completes the rendering to present the satellite orbit, satellite model and three-dimensional earth with three-dimensional effects on the main interface of the test platform.

[0072] Furthermore, during the test, if the communication terminal successfully accesses the network, the acquired latitude and longitude data of the communication terminal will be converted into a dynamic data format and then spliced ​​and loaded on the display layer. At this time, a three-dimensional model of the terminal will be presented at the specified location on the earth.

[0073] The communication display submodule 4230 is used to display the communication link between the communication terminal and the satellite.

[0074] Furthermore, the communication display submodule 4230 includes: a test time period selection unit 4231, a communication test data receiving unit 4232, a communication link state determination unit 4233 and a communication link display unit 4234.

[0075] The test time period selection unit 4231 is used to select a test time period from the process in which the satellite is visible to the communication terminal according to the terminal elevation angle.

[0076] Furthermore, the test time period selection unit 4231 includes:

[0077] The terminal pitch angle acquisition subunit is used to acquire the terminal pitch angle when the satellite is visible to the communication terminal according to the motion information of the communication terminal and the satellite;

[0078] Optionally, the terminal elevation angle may be acquired through simulation according to the location information of the communication terminal and the location information of the satellite.

[0079] In the embodiment of the present application, the test platform has built-in satellite orbit algorithm, satellite visibility algorithm, azimuth and pitch angle algorithm. For satellite systems that have not achieved global networking, the visibility time, azimuth, terminal pitch angle, current number of visible satellites and other parameters of the satellite to the terminal are calculated by inputting the satellite's two planetary ephemeris, terminal position, and simulation time period.

[0080] The transit time estimation subunit is used to estimate the transit time of the satellite based on the orbit information of the satellite, the position information of the communication terminal, and the position information of the satellite.

[0081] It should be noted that during the satellite transit, the communication terminal is visible for a certain period of time. The satellite transit time is the satellite visible time for the communication terminal. The satellite visible time for the communication terminal is discrete within a day. For example, within a day, the first visible time of a certain satellite to the communication terminal is 13 minutes, and the second visible time is 24 minutes. During the movement of the satellite, the size of the terminal pitch angle changes accordingly. The larger the range of the terminal pitch angle, the closer the communication terminal is to the middle position of the beam sent by the satellite, and the longer the satellite is visible to the communication terminal.

[0082] The selection subunit is used to select a test time period based on the transit time and the terminal pitch angle.

[0083] Optionally, when the pitch angle of the terminal is greater than a preset angle, the corresponding visible time can meet the test requirements, and the corresponding visible time is selected as the test time period. For example, the preset angle may be 30 degrees.

[0084] The communication test data receiving unit 4232 is used to receive communication test data between the communication terminal and the satellite during the test time period.

[0085] Optionally, the test time period is a time during which the satellite and the communication terminal can communicate. After the test time period is determined, communication test data between the communication terminal and the satellite is acquired during the test time period.

[0086] In the embodiment of the present application, the communication test data includes communication delay, communication rate and voice communication status. The test platform starts the command prompt window and uses the speed test server address to test the speed, sets the timeout time to 1 second, and repeats the speed test command every 1 second if the network is not connected, and sets the delay and rate data return value to 0. If the network is connected, the client's speed test tool is started, and after receiving the returned rate and delay data, the command will continue to be called to obtain the test data at the next moment. Before stopping the test, the test platform will cyclically run the command to obtain the communication rate and delay after receiving the test data.

[0087] The communication link status determination unit 4233 is used to determine the communication link status of the communication terminal according to the communication test data.

[0088] The communication link status determination unit further includes:

[0089] A communication test subunit, used to test whether the voice communication state is a preset state, and / or test whether the communication rate is greater than a preset rate;

[0090] The communication state identification subunit is used to identify that the communication state is normal in response to the voice communication state being a preset state and / or the communication rate being greater than a preset rate.

[0091] In an embodiment of the present application, the communication test data of the test platform is updated every 2 seconds, and the voice communication status and communication rate are screened in the communication test data. If the voice status is busy or the communication rate is not zero, it indicates that the business data is transmitted normally. If the voice status is idle and the communication rate is zero, it indicates that the communication process is interrupted.

[0092] The communication link display unit 4234 is used to visualize the real-time communication link between the communication terminal and the satellite based on the location information in response to the communication link status being normal.

[0093] The communication link display unit 4234 also includes:

[0094] The location information receiving subunit is used to receive the location information of the communication terminal according to a preset frequency. The location information may be the latitude and longitude data of the communication terminal.

[0095] As a possible implementation, the location information of the communication terminal is acquired through a built-in positioning module.

[0096] The mobile state determination subunit is used to associate the location information of the communication terminal with the time attribute to determine whether the communication terminal is in a mobile state.

[0097] Optionally, in the case where the communication terminal location sends a change, the location information is in a moving state.

[0098] Furthermore, the communication test data includes signal strength, communication link display unit, and also includes:

[0099] The path rendering subunit is used to determine the line format of the communication link according to the signal strength in response to the communication terminal being in a mobile state, and perform path rendering on the communication link based on the line format.

[0100] Optionally, the signal strength of the communication terminal may vary at different times or locations, and the communication link may be path rendered according to the signal strength to visualize the change in signal strength.

[0101] In the embodiment of the present application, when the terminal is in a moving state, the three-dimensional terminal entity moving path trajectory is dynamically updated in real time on the front-end earth layer, and at the same time, according to the current received satellite signal strength, the trajectory route of the terminal operation is distinguished in different line formats according to the signal strength, so as to more intuitively present the signal strength in different test areas. For example, the line format can be color, thickness, category, etc.

[0102] Furthermore, if the communication status is normal, it means that the terminal and the satellite have successfully transmitted business data. By adding a link entity to the map layer, a path-rendered communication link can be presented between the terminal and the satellite. If the communication process is interrupted, the communication link is removed synchronously.

[0103] Furthermore, the test terminal may also include a fault analysis module for performing fault analysis on the communication process between the communication terminal and the satellite.

[0104] Among them, the fault analysis module can perform fault analysis on each process of the communication terminal. Taking the network access process of the communication terminal as an example, the normal network access process is: the communication terminal performs signal search, sends a network access request, and the communication terminal successfully accesses the network. The fault analysis module obtains the communication process by parsing the communication protocol. If the communication process always shows signal search, it prompts that the cause of the fault is to check whether the core network is turned on and whether the onboard payload is turned on; if the communication process always stays at the network access request and cannot access the network, it prompts that the cause of the fault may be weak signal strength, disconnection of the USB interface, or the current satellite switching state. It is recommended to restart the communication terminal.

[0105] In this embodiment, the communication system includes: a satellite, a communication terminal, and a test platform, wherein the test platform includes a data playback module and a three-dimensional dynamic module, the communication terminal is used to communicate with the satellite, and obtain target data in the communication state, and the target data includes terminal state data and signal quality data; the satellite is used to send a satellite downlink signal to the test platform; the test platform is used to receive the satellite downlink signal, and perform spectrum and bandwidth analysis on the satellite downlink signal to obtain analysis results; the data playback module in the test platform is used to read and display at least one of the analysis results, communication test data and target data of the historical period, and the three-dimensional dynamic module is used to dynamically display the satellite communication process.
