Technical Field

[0001] The present invention relates to the field of communication technologies, and in particular, to a method, system, device, and medium for detecting satellite coverage anomalies. Background Art

[0002] In existing satellite communication systems, end users initiate satellite search services and access services at specific time points according to resources such as service base stations, feeder service arc segments, and service arc segments planned by satellite payloads. At this time, due to problems such as inaccurate time points of service arc segments planned by satellite payloads and excessive rain attenuation during abnormal weather, the actual coverage time points and ranges of satellite payloads may be inconsistent with the planned coverage time points and ranges. From the perspective of service impact, coverage anomalies may lead to behaviors that greatly affect the user service experience, such as abnormal access of end users, abnormal handover, abnormal call drops, and data transmission falling into pits, and it is necessary to quickly and accurately locate the root cause of the problem.

[0003] Currently, there is no fast and effective method in the satellite communication operation and maintenance subsystem to detect satellite coverage anomalies, and such problems cannot be quickly analyzed, located, and improved, thus affecting the customer's operation and maintenance perception. Summary of the Invention

[0004] In a satellite communication system, in view of the problem that there is no effective method in the above-mentioned operation and maintenance subsystem to detect satellite payload coverage anomalies, and when user service anomalies occur, it is necessary to quickly and accurately identify whether the cause of the problem is a satellite coverage anomaly, the present invention provides a method, system, device, and medium for detecting satellite coverage anomalies.

[0005] In a first aspect, the present invention provides a method for detecting satellite coverage anomalies, including:

[0006] Detecting the generation time point and disappearance time point of the AD signal;

[0007] Based on the generation time point and disappearance time point of the AD signal and the start time point and end time point of the service arc segment, determining whether the satellite coverage is abnormal.

[0008] In some embodiments, detecting the generation time point of the AD signal includes:

[0009] Taking the service arc segment a period of time t1 in advance as the start statistical time point T1, checking the reported start statistical time point T1, and taking the time point T2 that is greater than the start statistical time point T1 for the first time as the generation time point of the AD signal.

[0010] In some embodiments, detecting the disappearance time point of the AD signal includes:

[0014] Determine whether the satellite coverage is abnormal by comparing the satellite coverage error with the corresponding threshold.

[0015] In some embodiments, the satellite coverage error includes a coverage start error and a coverage end error, and the calculation methods are as follows:

[0016] Coverage start error T(start) = start time point of the service arc segment - generation time point of the AD signal;

[0017] Coverage end error T(end) = end time point of the service arc segment - disappearance time point of the AD signal.

[0018] In some embodiments, the threshold includes a threshold T(start threshold) corresponding to the coverage start error T(start) and a threshold T(end threshold) corresponding to the coverage end error T(end); thus, determining whether the satellite coverage is abnormal by comparing the satellite coverage error with the corresponding threshold includes:

[0019] If T(start) > T(start threshold) or T(end) > T(end threshold), then the satellite coverage is abnormal;

[0020] Otherwise, the satellite coverage is normal.

[0021] In a second aspect, the present invention provides a satellite coverage anomaly detection system, including:

[0022] A ground terminal device for detecting the generation time point and disappearance time point of the AD signal;

[0023] A satellite operation and maintenance subsystem for determining whether the satellite coverage is abnormal based on the generation time point and disappearance time point of the AD signal and the start time point and end time point of the service arc segment.

[0024] In some embodiments, the satellite operation and maintenance subsystem obtains the start time point and end time point corresponding to the service arc segment by acquiring the resource planning file of the satellite payload.

[0025] In a third aspect, the present invention provides an electronic device, comprising:

[0026] at least one processor; and a memory communicatively connected to the at least one processor;

[0027] wherein the memory stores instructions executable by the at least one processor, and the at least one processor, by executing the instructions stored in the memory, causes the at least one processor to execute the above method.

[0030] Through the detection of the AD signal of the terminal, the present invention can obtain in real time the start time point and the end time point when the satellite payload actually covers the terminal user. By comparing the actual time points with the time points planned in the service arc segment, it can quickly and accurately detect whether the satellite payload coverage is abnormal, thereby enhancing the user's operation and maintenance perception.

[0035] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. The components of the embodiments of the present invention described and illustrated herein can be arranged and designed in various different configurations.

[0036] Accordingly, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the claimed invention, but merely represents selected embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the scope of protection of the present invention.

[0037] As Figure 1 shown, an embodiment of the present invention provides a method for detecting satellite coverage anomalies, including:

[0038] S100, detecting the generation time point and disappearance time point of the AD signal;

[0039] S200, determining whether the satellite coverage is abnormal based on the generation time point and disappearance time point of the AD signal and the start time point and end time point of the service arc segment.

[0040] In step S100, the generation time point and disappearance time point of the AD signal can be detected in real time by a ground terminal device. Among them:

[0041] For the generation time point of the AD signal:

[0042] If the time point carried by the detected AD signal is the generation time point of the detected AD signal, advance the service arc segment by a period of time t1 as the start statistical time point T1, view the reported start statistical time point T1, and take the time point T2 that is greater than the start statistical time point T1 for the first time as the earliest detected time point of the signal, that is, the generation time point of the AD signal.

[0043] The above period of time t1 is set according to needs and experience. For example, it is set to 5s. At this time, it is considered that the AD signal is probably not detected, and the first detection of the AD signal is after this time point advanced by a period of time t1. Then, as Figure 2 shown, an example is given to illustrate the generation time point of the AD signal: advance the service arc segment (start time point is 11:30:40s) by 5s, detect the start statistical time point T1 (11:30:35s), and take the time point T2 (11:30:41s) that is greater than the start statistical time point T1 (11:30:35s) for the first time as the earliest detected time point of the AD signal, that is, the generation time point of the AD signal.

[0044] For the disappearance time point of the AD signal:

[0045] If the time point carried by the detected AD signal is the disappearance time point of the detected AD signal, delay the service arc segment by a period of time t2 as the end statistical time point T3, view the reported end statistical time point T3, and take the end statistical time point T3 as the latest detected time point of the AD signal, that is, the disappearance time point of the AD signal.

[0046] The above-mentioned period of time t2 is set according to requirements and experience. For example, it is set to 5s, and at this time, it is considered that the AD signal has disappeared. Then, as Figure 2 shown, an example is given to illustrate the disappearance time point of the AD signal: Delay the service arc segment (the end time point is 11:37:20s) by a period of 5s as the end statistical time point T3 (11:37:25s), that is, the disappearance time point of the AD signal.

[0047] In step S200, it is possible to determine whether the satellite coverage is abnormal through the satellite operation and maintenance subsystem based on the generation time point and disappearance time point of the AD signal, as well as the start time point and end time point of the service arc segment. The satellite operation and maintenance subsystem can obtain the resource planning file of the satellite payload, including the mapping relationship between the base station and the satellite, the satellite payload power supply, and the start time point and end time point corresponding to the service arc segment. The determination of whether the satellite coverage is abnormal based on the generation time point and disappearance time point of the AD signal, as well as the start time point and end time point of the service arc segment, is as follows:

[0048] S201. Calculate the satellite coverage error according to the generation time point and disappearance time point of the AD signal and the start time point and end time point of the service arc segment respectively;

[0049] S202. Determine whether the satellite coverage is abnormal by comparing the satellite coverage error with the corresponding threshold.

[0050] In step S201, the satellite coverage error includes a coverage start error and a coverage end error, and the calculation methods are as follows:

[0051] Coverage start error T(start) = start time point of the service arc segment - generation time point of the AD signal;

[0052] Coverage end error T(end) = end time point of the service arc segment - disappearance time point of the AD signal.

[0053] In step S202, the thresholds include a threshold T(start threshold) corresponding to the coverage start error T(start) and a threshold T(end threshold) corresponding to the coverage end error T(end). Thus, determining whether the satellite coverage is abnormal by comparing the satellite coverage error with the corresponding threshold includes:

[0054] If T(start) > T(start threshold) or T(end) > T(end threshold), then the satellite coverage is abnormal;

[0055] Otherwise, the satellite coverage is normal.

[0056] Based on the same inventive concept, as Figure 3 shown, an embodiment of the present invention also provides a satellite coverage anomaly detection system, including:

[0057] A ground terminal device for detecting the generation time point and disappearance time point of an AD signal;
