[0024] The following describes in detail embodiments of the present disclosure, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present disclosure, and should not be construed as limiting the present disclosure.

[0025] In order to better understand the network testing method, device and network testing system of the satellite Internet disclosed in the embodiments of the present disclosure, the satellite communication system to which the embodiments of the present disclosure are applicable is first described below.

[0026] See Figure 1 , Figure 1 Schematic diagram of the architecture of a satellite communication system provided by an embodiment of the present disclosure. The satellite communication system may include but is not limited to a satellite 101 and a test terminal 102. Figure 1 The number and form of the devices shown are for example only and do not constitute a limitation on the embodiments of the present disclosure. In actual applications, two or more satellites and two or more test terminals may be included.

[0027] The satellite 101 in the embodiment of the present disclosure is an entity for transmitting or receiving signals. The embodiment of the present disclosure does not limit the specific technology and specific device form used by the satellite.

[0028] In the embodiments of this disclosure, test terminal 102 refers to a device within the satellite's coverage beam that is used to communicate with a satellite and test the communication signals. For example, the test terminal can be a car with satellite communication capabilities, a smart car, a mobile phone, a wearable device, a tablet computer, and so on. The embodiments of this disclosure do not limit the specific technology or device form factor used by the test terminal.

[0029] It can be understood that the satellite communication system described in the embodiment of the present disclosure is intended to more clearly illustrate the technical solution of the embodiment of the present disclosure, and does not constitute a limitation on the technical solution provided by the embodiment of the present disclosure. Ordinary technicians in this field can know that with the evolution of system architecture and the emergence of new business scenarios, the technical solution provided by the embodiment of the present disclosure is also applicable to similar technical problems.

[0030] In the aforementioned satellite communication systems, the satellites are in motion, resulting in significant differences in the network coverage characteristics of satellite internet and terrestrial mobile communication systems. For example, satellite internet operates in a wider range of frequency bands, making the drive testing methods used for terrestrial mobile communication systems inapplicable to satellite internet. Therefore, implementing network testing for satellite internet, which utilizes multi-band communication, is an urgent challenge.

[0031] The disclosed embodiments provide a satellite internet network testing method, apparatus, control device, electronic device, storage medium, and network testing system. The satellite internet network testing method includes: a control device sending test task information to any one of a plurality of test terminals; the test task information includes: frequency band information of a frequency band to be tested and identification information of a satellite to be tested, wherein the frequency band to be tested is different from the frequency band to be tested of at least one of the plurality of test terminals; the target terminal receives a communication signal within the frequency band to be tested from the satellite to be tested, and tests the communication signal to obtain test data information; the control device obtains the test data information from the target terminal, and determines a signal quality parameter based on the test data information. Thus, any one of the plurality of test terminals can be used to test a communication signal within a corresponding frequency band to be tested received from a corresponding satellite to be tested, wherein the frequency band to be tested is different from the frequency band to be tested of at least one of the plurality of test terminals, thereby achieving network testing of a satellite internet using multi-band communication.

[0032] The following, in conjunction with the accompanying drawings, describes in detail the satellite internet network testing method, apparatus, control device, electronic device, storage medium, and network testing system provided by the present disclosure. First, the satellite internet network testing system is described. In various embodiments of the present disclosure, the satellite internet network testing system is referred to as the network testing system.

[0033] Figure 2 A schematic structural diagram of a satellite Internet network testing system provided in an embodiment of the present disclosure.

[0034] like Figure 2 As shown, the satellite Internet network test system may include but is not limited to: a control device 201 and multiple test terminals. Figure 2In the example, five test terminals are used, namely test terminal 202, test terminal 203, test terminal 204, test terminal 205, and test terminal 206. The control device 201 is in communication connection with the plurality of test terminals.

[0035] The control device 201 is configured to send test task information to any target terminal among the multiple test terminals; the test task information includes frequency band information of a frequency band to be tested and identification information of a satellite to be tested, wherein the frequency band to be tested is different from the frequency band to be tested of at least one test terminal among the multiple test terminals; the at least one test terminal is at least one test terminal other than the target terminal in the network test system;

[0036] Any target terminal among the multiple test terminals is used to receive a communication signal within a frequency band to be tested from a satellite to be tested, and test the communication signal to obtain test data information;

[0037] The control device 201 is further configured to obtain test data information from the target terminal and determine a signal quality parameter based on the test data information.

[0038] The control device 201 is a device in the network test system that can control the test process.

[0039] In some embodiments, the control device 201 may include a display control device and a main control device.

[0040] Among them, the display and control equipment has built-in display and control software, which can provide rich human-computer interaction interfaces, support testers to test control and status monitoring of the network test system, and perform statistics and analysis on various types of collected data.

[0041] The master control device contains built-in master control software, master control hardware, and other functional modules. It provides a rich set of hardware expansion interfaces and can connect to test terminals and other devices or modules in the network test system via USB (Universal Serial Bus) or LAN (Local Area Network) interfaces to execute test tasks. The master control hardware includes a processor that runs the master control software and is used for data analysis and processing.

[0042] It is understandable that when a network test of the satellite Internet is required, the tester can send test task information to any target terminal among the multiple test terminals through the control device 201. The test task information includes: frequency band information of the frequency band to be tested and identification information of the satellite to be tested. The frequency band to be tested is different from the frequency band to be tested of at least one test terminal among the multiple test terminals. The frequency band to be tested is the working frequency band that the target terminal needs to test. The frequency band information of the frequency band to be tested can include any information related to the frequency band to be tested, such as the frequency band name or identification, frequency range, wavelength corresponding to the frequency band, etc. The satellite to be tested is the satellite that the target terminal needs to connect to and perform signal testing. The satellite identification of the satellite to be tested is used to uniquely identify the corresponding satellite. The satellites that different test terminals need to connect to and test can be the same or different, and this disclosure does not limit this.

[0043] Among them, the frequency bands to be tested may include, for example, C band (4-8 GHz), Ku band (12-18 GHz), Ka band (26.5-40 GHz), L band (1-2 GHz), S band (2-4 GHz), etc., and the present disclosure does not impose any restrictions on this.

[0044] After receiving the test mission information, any target terminal can receive communication signals within the test frequency band from the corresponding satellite under test, test the communication signals, and obtain corresponding test data information. The test data information may include data related to the communication signal, the communication signal in the presence of interference signals, or the downlink common channel of the satellite under test.

[0045] It should be noted that, in some embodiments, the control device 201 can send corresponding test task information to multiple test terminals respectively, where the test task information includes frequency band information of the frequency band to be tested corresponding to the test terminal and identification information of the satellite to be tested corresponding to the test terminal, where the frequency band to be tested corresponding to any test terminal is different from the frequency band to be tested of at least one other test terminal. After receiving the corresponding test task information sent by the control device 201, multiple test terminals can receive communication signals in the corresponding frequency band to be tested from the corresponding satellite to be tested in parallel, and test the received corresponding communication signals to obtain test data information corresponding to the corresponding communication signals.

[0046] The control device 201 may obtain test data information from any target terminal among the multiple test terminals, and determine a corresponding signal quality parameter based on the test data information.

[0047] Among them, signal quality parameters are key indicators used to measure various performance or channel performance during signal transmission, such as signal strength, bit error rate, signal-to-noise ratio, RSRP (Reference Signal Receiving Power), channel power strength, etc.

[0048] In some embodiments, the control device may filter, organize, summarize or convert the test data information to obtain signal quality parameters.

[0049] In some embodiments, any test terminal has a display function and can display corresponding test data information, so that the tester can intuitively see the test data information from the test terminal.

[0050] Therefore, any target terminal among multiple test terminals can be used to test the communication signal in the corresponding test frequency band received from the corresponding test satellite, where the test frequency band is different from the test frequency band of at least one test terminal among the multiple test terminals, thereby realizing network testing of satellite Internet using multi-band communication.

[0051] The following combination Figure 3 , further illustrates the satellite Internet network testing system provided by the embodiment of the present disclosure.

[0052] Figure 3 A schematic structural diagram of another satellite Internet network testing system provided in an embodiment of the present disclosure.

[0053] refer to Figure 3 The satellite internet network test system may include but is not limited to: a control device 201 and multiple test terminals. Figure 3 In the example, five test terminals are used, namely test terminal 202, test terminal 203, test terminal 204, test terminal 205, and test terminal 206. The control device 201 is in communication connection with the plurality of test terminals.

[0054] In some embodiments, network testing of satellite internet services may include coverage testing of the satellite internet services. Coverage testing primarily assesses the coverage of satellite communication services. Accordingly, any target terminal in the network testing system may be used to perform coverage testing.

[0055] Accordingly, the control device 201 is configured to send test task information to any target terminal among the multiple test terminals; wherein the test task information includes subtask information of the coverage test, and the subtask information of the coverage test includes: frequency band information of the frequency band to be tested and identification information of the satellite to be tested;

[0056] The target terminal is used to receive the communication signal within the frequency band to be tested from the satellite to be tested, and perform coverage test on the communication signal to obtain corresponding test data information;

[0057] The control device 201 is also used to obtain test data information obtained by performing coverage testing on the communication signal from the target terminal, and based on the test data information obtained by performing coverage testing on the communication signal, determine at least one of the signal strength, bit error rate, and reference signal received power RSRP of the communication signal in the signal quality parameters.

[0058] The frequency band to be tested for coverage testing is the working frequency band on which the target terminal needs to perform coverage testing, and can be set as needed. The satellite to be tested for coverage testing is the satellite to which the target terminal needs to connect and perform signal coverage testing, and can be set as needed.

[0059] The test data information obtained by performing coverage testing on the communication signal may include data information related to the coverage performance of the communication signal.

[0060] Among them, the signal strength, bit error rate, and reference signal received power RSRP of the communication signal can reflect the signal quality of the communication signal.

[0061] In some embodiments, in the network testing system, at least one other test terminal other than the target terminal may also receive test task information, including sub-task information of coverage testing, the sub-task information of coverage testing including: frequency band information of the frequency band to be tested for coverage testing and identification information of the satellite to be tested, and perform coverage testing on the communication signal within the corresponding frequency band to be tested received from the corresponding satellite to be tested, wherein the frequency band to be tested for coverage testing corresponding to the target terminal may be different from the frequency band to be tested for coverage testing corresponding to at least one other test terminal.

[0062] In this way, coverage testing of satellite Internet using multi-band communication is achieved, and the signal quality of satellite Internet communication signals in multiple frequency bands is obtained.

[0063] In some embodiments, network testing of the satellite internet system may include service testing of the satellite internet system. Service testing primarily tests the various service functions provided by the satellite internet system. Accordingly, any target terminal in the network testing system may be used to perform service testing.

[0064] Accordingly, the control device 201 is configured to send test task information to any target terminal among the multiple test terminals; wherein the test task information includes subtask information of the service test, and the subtask information of the carrier test includes: frequency band information of the frequency band to be tested in the service test and identification information of the satellite to be tested;

[0065] The target terminal is used to receive the communication signal within the frequency band to be tested from the satellite to be tested, and perform service tests on the communication signal to obtain corresponding test data information;

[0066] The control device 201 is further configured to obtain test data information obtained by performing a service test on the communication signal from the target terminal, and determine a signal quality parameter based on the test data information obtained by performing a service test on the communication signal.

[0067] Among them, signal quality parameters may include throughput, packet loss rate, signal strength, etc.

[0068] The frequency band to be tested for the service test is the working frequency band on which the target terminal needs to perform the service test, and can be set as needed. The satellite to be tested for the service test is the satellite to which the target terminal needs to connect and perform the signal service test, and can be set as needed.

[0069] The test data information obtained by performing service tests on communication signals may include data information related to service functions.

[0070] In some embodiments, in the network testing system, at least one other test terminal other than the target terminal may also receive test task information, including sub-task information of service testing, the sub-task information of service testing including: frequency band information of the frequency band to be tested for service testing and identification information of the satellite to be tested, and perform service testing on the communication signal within the corresponding frequency band to be tested received from the corresponding satellite to be tested, wherein the frequency band to be tested for service testing corresponding to the target terminal may be different from the frequency band to be tested for service testing corresponding to at least one other test terminal.

[0071] This has enabled business testing of satellite Internet using multi-band communications.

[0072] In some embodiments, network testing of satellite internet may include carrier testing of the satellite internet. Carrier testing primarily involves testing satellite communication links. Accordingly, any target terminal in the network testing system may be used to perform carrier testing.

[0073] Accordingly, the control device 201 is configured to send test task information to any target terminal among the multiple test terminals; wherein the test task information includes subtask information of the carrier test, and the subtask information of the carrier test includes: frequency band information of the frequency band to be tested of the carrier test and identification information of the satellite to be tested;

[0074] The target terminal is used to receive the communication signal within the frequency band to be tested from the satellite to be tested, and perform carrier testing on the communication signal to obtain corresponding test data information;

[0075] The control device 201 is also used to obtain test data information obtained by performing a carrier test on the communication signal from the target terminal, and based on the test data information obtained by performing a carrier test on the communication signal, determine at least one of the power intensity and signal-to-noise ratio of the downlink common channel of the satellite to be tested in the signal quality parameters.

[0076] The frequency band to be tested for the carrier test is the operating frequency band on which the target terminal needs to perform the carrier test, and can be set as needed. The satellite to be tested for the carrier test is the satellite to which the target terminal needs to connect and perform the signal carrier test, and can be set as needed.

[0077] The test data information obtained by performing a carrier test on the communication signal may include data information related to the downlink common channel of the satellite to be tested.

[0078] In some embodiments, in the network testing system, at least one other test terminal other than the target terminal may also receive test task information, including sub-task information of the carrier test, the sub-task information of the carrier test including: frequency band information of the frequency band to be tested of the carrier test and identification information of the satellite to be tested, and perform carrier testing on the communication signal in the corresponding frequency band to be tested received from the corresponding satellite to be tested, wherein the frequency band to be tested of the carrier test corresponding to the target terminal may be different from the frequency band to be tested of the carrier test corresponding to at least one other test terminal.

[0079] This enables carrier testing of satellite Internet using multi-band communications.

[0080] In some embodiments, the network testing system may first perform a coverage or service test to obtain signal quality parameters corresponding to communication signals within multiple test frequency bands received from at least one test satellite, such as signal strength, bit error rate, and reference signal received power (RSRP). If, among these communication signals, at least one signal quality parameter corresponding to a communication signal within a target frequency band received from any target satellite is lower than a corresponding preset threshold, the signal quality of the communication signal within the target frequency band received from the target satellite may be considered poor. The control device 201 may then select the target frequency band as the test frequency band for a carrier test, select the target satellite as the test satellite for the carrier test, and send carrier test subtask information to any target terminal among the multiple test terminals for performing the carrier test. The carrier test subtask information includes frequency band information of the target frequency band and identification information of the target satellite. After receiving the carrier test subtask information, the target terminal may receive the communication signal within the target frequency band from the target satellite, perform a carrier test on the communication signal, obtain corresponding test data, and determine at least one of the power strength and signal-to-noise ratio of the downlink common channel of the target satellite based on the test data obtained from the carrier test on the communication signal.

[0081] The preset threshold value can be set as needed, and the present disclosure does not impose any restrictions on this.

[0082] Therefore, for a communication signal within a target frequency band received from a target satellite, when at least one signal quality parameter corresponding to the communication signal is lower than a corresponding preset threshold, the cause of the poor signal quality of the communication signal can be found through carrier testing.

[0083] In some embodiments, any target terminal among the multiple test terminals can also be used to perform interference testing.

[0084] Accordingly, the control device 201 is configured to send test task information to any target terminal among the multiple test terminals; wherein the test task information includes subtask information of the interference test, and the subtask information of the interference test includes: frequency band information of the frequency band to be tested for the interference test and identification information of the satellite to be tested;

[0085] The target terminal is used to receive the communication signal within the frequency band to be tested from the satellite to be tested, and perform interference testing on the communication signal to obtain corresponding test data information;

[0086] The control device 201 is also used to obtain test data information obtained by performing interference tests on communication signals from the target terminal, and determine at least one of the timing offset, frequency offset, time domain power and frequency domain power spectrum of the downlink beam of the satellite to be tested in the signal quality parameters based on the test data information obtained by performing interference tests on the communication signals.

[0087] The frequency band to be tested for the interference test is the working frequency band on which the target terminal needs to perform the interference test, and can be set as needed. The satellite to be tested for the interference test is the satellite to which the target terminal needs to connect and perform the signal interference test, and can be set as needed.

[0088] The test data information obtained by performing interference testing on the communication signal may include relevant information of the communication signal in the presence of the interference signal, such as the bit error rate of the communication signal.

[0089] In some embodiments, in the network testing system, at least one other test terminal other than the target terminal may also receive test task information, including sub-task information of the interference test, the sub-task information of the interference test including: frequency band information of the frequency band to be tested for the interference test and identification information of the satellite to be tested, and perform carrier testing on the communication signal within the corresponding frequency band to be tested received from the corresponding satellite to be tested, wherein the frequency band to be tested for the interference test corresponding to the target terminal may be different from the frequency band to be tested for the interference test corresponding to at least one other test terminal.

[0090] In some embodiments, a test terminal used for performing a carrier test is referred to as a carrier test terminal. The target terminal may be the carrier test terminal. The carrier test terminal may receive a communication signal within any frequency band from any satellite, perform an interference test on the communication signal, obtain corresponding test data information, and use the test data information to determine whether an interference signal exists in the communication signal. If an interference signal exists, the energy of the interference signal and the frequency band to which it belongs are determined. The interference signal may be in-band interference within the bandwidth of the frequency band or out-of-band interference outside the bandwidth of the frequency band, and this disclosure is not limited thereto.

[0091] For example, the carrier test terminal can receive a communication signal within a frequency band to be tested from a satellite to be tested, and perform an interference test on the communication signal to obtain corresponding test data information. Based on the test data information, it is determined whether there is a signal with a signal strength greater than a strength threshold outside the bandwidth of the frequency band. If so, the signal can be determined as an interference signal, and based on the test data information, the energy of the interference signal and the frequency band to which it belongs can be determined.

[0092] In addition, the control device 201 can read the test data information from the carrier test terminal, and thereby determine the interference signal existing in the corresponding communication signal based on the test data information, and determine the energy of the interference signal and the frequency band to which it belongs.

[0093] This enables interference testing of satellite Internet using multi-band communications.

[0094] In some embodiments, any test terminal included in the network test system can be used to perform any type of test in the above embodiments. Furthermore, the network test system can include test terminals for performing different types of tests. For example, in the embodiments of the present application, a test terminal for performing a carrier test is referred to as a carrier test terminal, and a test terminal for performing a coverage test is referred to as a coverage test terminal. The network test system can include multiple coverage test terminals and at least one carrier test terminal. Among them, for a test terminal that performs a certain type of test, the control device 201 can send test task information to multiple test terminals in parallel, wherein the test task information includes the frequency band information of the frequency band to be tested corresponding to the test terminal and the identification information of the satellite to be tested. Different test terminals correspond to different frequency bands to be tested, so that multiple test terminals are used to test the communication signals in the corresponding frequency band to be tested received from the corresponding satellite to be tested; or, the control device 201 can also send test task information to the same test terminal successively, wherein the test task information includes the frequency band information of the frequency band to be tested and the identification information of the satellite to be tested. The frequency band to be tested in the test task information sent at different times is different, so that the same test terminal is used to test the communication signals in different frequency bands to be tested received from at least one satellite to be tested, so as to save the number of test terminals.

[0095] For example, in the embodiment of the present application, a single carrier test terminal may be used to sequentially receive test task information to perform carrier testing on communication signals in different test frequency bands received from at least one test satellite, or multiple coverage test terminals may be used to perform coverage testing on communication signals in corresponding test frequency bands received from corresponding test satellites in parallel. Figure 3 The test terminal 202, test terminal 203, test terminal 204, and test terminal 205 can be coverage test terminals, and the test terminal 206 can be a carrier test terminal. The test terminal 202 can perform coverage testing on the communication signal within the test band 1 received from satellite 1, the test terminal 203 can perform coverage testing on the communication signal within the test band 2 received from satellite 1, the test terminal 204 can perform coverage testing on the communication signal within the test band 3 received from satellite 2, and the test terminal 205 can perform coverage testing on the communication signal within the test band 4 received from satellite 2. The test terminal 206 can perform carrier testing on the communication signal within the test band 1 received from satellite 1, the communication signal within the test band 2 received from satellite 1, the communication signal within the test band 3 received from satellite 2, and the communication signal within the test band 4 received from satellite 2 in sequence.

[0096] In some embodiments, because the antenna configurations for receiving communication signals in different frequency bands may differ, the network test system may include multiple satellite communication antennas. Each test terminal may have at least one corresponding satellite communication antenna to receive communication signals within the corresponding frequency band to be tested from the corresponding satellite to be tested via the corresponding satellite communication antenna. Furthermore, test terminals with different protocol systems require corresponding satellite communication antennas. When the network test system includes test terminals for performing different types of tests, there may be cases where the test terminals for performing different types of tests correspond to the same frequency band to be tested. For example, in the above example, the frequency band to be tested corresponding to test terminal 206 includes the frequency band to be tested corresponding to test terminals 202, 203, 204, and 205. To reduce the number of satellite communication antennas included in the network test system when the test allows, when the network test system includes multiple satellite communication antennas, an RF switching module can be used to combine antennas of the same type.

[0097] For example, taking multiple test terminals in a network test system, including multiple coverage test terminals and at least one carrier test terminal, an RF switching module can be used to combine antennas of the same type, that is, the RF switching module can be used to enable the carrier test terminal to share the satellite communication antennas corresponding to multiple coverage test terminals.

[0098] refer to Figure 3 , assuming Figure 3In the example, test terminals 202, 203, 204, and 205 are coverage test terminals, test terminal 206 is a carrier test terminal, and satellite communication antennas 302, 303, 304, and 305 correspond to test terminals 202, 203, 204, and 205, respectively. A radio frequency switching module 301 can be used to allow test terminal 206 to share satellite communication antennas 302, 303, 304, and 305. When performing coverage testing on communication signals received from a corresponding satellite under test within a corresponding frequency band under test via test terminals 202, 203, 204, and 205, the test terminals 202, 203, 204, and 205 can be connected to the corresponding satellite communication antennas via the radio frequency switching module 301. When performing a carrier test on a communication signal within a target frequency band received from a target satellite via test terminal 206, the operating state of RF switching module 301 can be switched, thereby connecting test terminal 206 to the target antenna via RF switching module 301. The target satellite is the satellite to be tested for the carrier test, and the target frequency band is the frequency band to be tested for the carrier test. The frequency band corresponding to the target antenna is the frequency band to be tested for the carrier test.

[0099] Accordingly, for any target terminal among the multiple test terminals, when the target terminal is a carrier test terminal, the control device 201 or the target terminal is configured to determine the target antenna from the antennas corresponding to the multiple coverage test terminals, wherein the corresponding frequency band of the target antenna is the frequency band to be tested for the carrier test, and the control device 201 may send a switching instruction to the RF switching module 301, wherein the switching instruction carries identification information of the target antenna;

[0100] The radio frequency switching module 301 is used to connect the carrier test terminal to the target antenna based on the identification information of the target antenna;

[0101] The carrier test terminal is configured to receive a communication signal within a frequency band to be tested from a satellite to be tested via the target antenna in response to establishing a connection with the target antenna via the RF switching module 301. The satellite to be tested is a satellite to be tested for carrier testing.

[0102] Thus, by using the RF switching module 301, a test terminal performing a certain type of test can share the satellite communication antenna corresponding to a test terminal performing another type of test. Depending on different scenarios, the satellite communication antenna can be switched to connect to the test terminal performing different types of tests, thereby reducing the number of satellite communication antennas in the network test system and making the network testing process more flexible and efficient. By using the RF switching module, carrier test terminals can share the satellite communication antennas corresponding to multiple coverage test terminals. If the signal quality of a communication signal within a target frequency band received by a coverage test terminal from a target satellite is poor, the carrier test terminal can be directly connected to the satellite communication antenna corresponding to the coverage test terminal through the RF switching module to receive the communication signal within the target frequency band from the target satellite, thereby performing carrier testing, thereby making testing more convenient and efficient.

[0103] It should be noted that in the embodiments of the present disclosure, certain types of test terminals can be used to conduct service testing, focusing on service testing from the user's perspective and reporting test data information. Certain types of test terminals, such as carrier test terminals, can also be used to conduct testing independent of the network, focusing on network coverage testing and interference testing.

[0104] In some embodiments, the test task information received by any target terminal among the multiple test terminals may further include a test time period and a test location. The test time period is the time period during which the target terminal performs the test, and the test location is the location at which the target terminal is located during the test.

[0105] After receiving the test task information, the target terminal can receive the communication signal within the test frequency band from the test satellite within the corresponding test time period and at the corresponding test position, and test the communication signal to obtain corresponding test data information.

[0106] In some embodiments, the target terminal can obtain the real-time time, the real-time location of the target terminal, and the actual satellite communicating with the target terminal during the test process, and compare the real-time time with the test time period corresponding to the target terminal, compare the real-time location with the test location corresponding to the target terminal, and compare the actual satellite with the satellite to be tested corresponding to the target terminal. The test is stopped if at least one of the following conditions is met: the real-time time is not within the test time period corresponding to the target terminal, the real-time location does not match the test location corresponding to the target terminal, and the actual satellite does not match the satellite to be tested corresponding to the target terminal.

[0107] It should be noted that for test terminals performing different types of tests, the test time period and test location in the received test task information can be the same or different, for example, both are 11 o'clock-12 o'clock, or the same or different longitude, latitude and altitude.

[0108] Furthermore, when at least one of the above conditions is met, the target terminal may also issue an alarm.

[0109] In this way, it can be ensured that any test terminal completes the network test of the satellite Internet according to the test time period and test location in the received test task information.

For communication signals received from a target satellite within a target frequency band, if at least one signal quality parameter corresponding to the communication signal falls below a corresponding preset threshold, carrier testing can be used to identify the cause of the poor signal quality. By using a radio frequency switching module to combine antennas of the same type and switching satellite communication antennas to connect to test terminals performing different types of tests based on different scenarios, the number of satellite communication antennas in the network testing system is reduced, making the network testing process more flexible and efficient.

[0158] The test data information may include data information related to communication signals, communication signals in the presence of interference signals, or downlink common channels of the satellite to be tested.

[0159] In some embodiments, the target terminal may send test data information to the control device, so that the control device may determine the signal quality parameter based on the received test data information.

[0160] Among them, signal quality parameters are key indicators used to measure various performance or channel performance during signal transmission, such as signal strength, bit error rate, signal-to-noise ratio, RSRP, channel power strength, etc.

[0161] In some embodiments, the test task information includes sub-task information of the coverage test, and the sub-task information of the coverage test includes: frequency band information of the frequency band to be tested for the coverage test and identification information of the satellite to be tested; accordingly, step 503 can be implemented in the following manner: performing a coverage test on the communication signal to determine at least one of the signal strength, bit error rate, and reference signal received power RSRP of the communication signal in the signal quality parameters based on the test data information obtained from the coverage test.
