Description

Technical Field

[0001] The present invention relates to the technical field of satellite communication and wireless mobile communication, and more specifically, to a communication signal anomaly determination method, an access terminal and a computer-readable storage medium. Background Art

[0002] In satellite communication systems, signal attenuation and abnormality are often caused by a variety of reasons:

[0003] First, the reasons for signal blocking. When the access terminal is installed on a mobile carrier such as a ship or vehicle, due to structural limitations of the installation carrier or unreasonable engineering installation location, when there are certain mobile azimuths blocked at the installation location of the access terminal, the signal transmission will be blocked and cause signal attenuation. For example, when the mast of the installation carrier ship is very high, the access terminal installation location and the service satellite wireless signal are blocked by the mast at certain azimuths, resulting in poor receiving and sending signals between the access terminal and the service satellite, reduced system throughput, and disconnection of the wireless link between the access terminal and the service satellite, which affects the overall network throughput and operational KPI indicators of the broadband satellite communication system.

[0004] Second, weather conditions. When the weather is severe, such as heavy rain, strong winds, thunder and lightning, the receiving and sending signals between the access terminal and the service satellite are poor, the system throughput decreases, and the wireless link between the access terminal and the service satellite is disconnected, which affects the overall network throughput and operational KPI indicators of the broadband satellite communication system.

[0005] Third, there are unavoidable reasons such as failure of the access terminal itself.

[0006] The above three main reasons lead to signal attenuation and anomalies, which greatly affect the user service quality and easily lead to users filing complaints due to poor application experience. At present, the reasons that cause signal attenuation and anomalies cannot be determined, and it is difficult to handle user complaints in a timely manner. At the same time, it brings many troubles to the operation and maintenance staff, further reducing the user experience satisfaction and to a certain extent reducing the reliability of the satellite communication system.

[0027] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the following is a further detailed description of the embodiments of the present invention through specific implementation methods combined with the accompanying drawings. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0028] Embodiment 1:

[0029] In order to solve the problem that the prior art fails to determine the cause of signal attenuation and abnormality, resulting in the inability to handle user complaints in a timely manner, causing certain troubles to operation and maintenance personnel, a communication signal abnormality determination method is provided in an embodiment of the present invention. When the access terminal signal is abnormal, parameter information affecting the access terminal signal is obtained, and further, the parameter information is analyzed, and the cause of the access terminal signal abnormality is determined according to the analysis result; see Figure 1 As shown, Figure 1 A schematic diagram of the basic flow of the communication signal abnormality determination method provided in this embodiment.

[0030] S101: When an access terminal signal is abnormal, obtain parameter information affecting the access terminal signal.

[0031] Optionally, in this embodiment, whether the access terminal signal is abnormal can be determined by acquiring signal characterization parameter information of the access terminal. For example, when the signal characterization parameter information is a signal-to-noise ratio, the average signal-to-noise ratio currently acquired periodically is compared with the historical average signal-to-noise ratio, wherein the average signal-to-noise ratio currently acquired periodically can be obtained by averaging multiple acquired signal-to-noise ratios after filtering, and the historical average signal-to-noise ratio can be obtained by averaging multiple signal-to-noise ratios acquired in multiple periods after filtering. When the average signal-to-noise ratio currently acquired periodically is greater than or equal to the historical average signal-to-noise ratio, it indicates that the access terminal signal is normal; when the average signal-to-noise ratio currently acquired periodically is less than the historical average signal-to-noise ratio, it indicates that the access terminal signal is abnormal.

[0032] It is worth noting that what is listed here is only a feasible way to determine whether the access terminal signal is abnormal. The present invention is not limited to the listed method. In fact, as long as it is a method that can determine whether the access terminal signal is abnormal, it is within the protection scope of the present invention. In actual applications, it needs to be flexibly adjusted according to the application scenario.

[0033] Optionally, parameter information affecting the access terminal signal in this embodiment includes but is not limited to the first position information of the access terminal, the second position information of the service satellite, weather information, and relative position information of the access terminal and the obstruction on the mobile carrier, wherein it should be understood that the access terminal is installed on the mobile carrier.

[0034] It is worth noting that in order to better understand the present invention, this embodiment uses the three main reasons for the abnormal access terminal signal as examples, namely, the signal between the access terminal and the service satellite is blocked, the weather conditions, and the access terminal fails. The present invention is not limited to these three reasons for the abnormal access terminal signal. In actual applications, it can be flexibly adjusted according to the specific application scenario. At the same time, the parameter information affecting the access terminal signal obtained according to the specific reason can also be flexibly adjusted.

[0035] S102: Analyze the parameter information and determine the cause of abnormal signal of the access terminal according to the analysis result.

[0036] First, the reason for the abnormal access terminal signal is that the communication signal between the access terminal and the service satellite is blocked:

[0037] In this embodiment, when the parameter information includes the first location information of the access terminal, the first location information of the access terminal is periodically acquired;

[0038] Further, calculating the moving azimuth of the access terminal according to the periodically acquired first location information;

[0039] Optionally, the first location information includes longitude and latitude information, wherein calculating the moving azimuth of the access terminal based on the periodically acquired first location information includes: taking the longitude and latitude positions in the longitude and latitude information acquired in the previous period as the origin, and calculating the angle between the moving direction of the longitude and latitude positions in the longitude and latitude information acquired in the current period relative to the origin and the true north direction.

[0040] Further, the azimuth of communication between the access terminal and the service satellite is calculated based on the latest first location information and second location information periodically acquired;

[0041] Optionally, the first location information includes longitude and latitude information, and the second location information includes longitude information, wherein the azimuth of communication between the access terminal and the service satellite is calculated based on the latest first location information and second location information periodically acquired, including: taking the longitude and latitude positions in the longitude and latitude information as the origin, and calculating the angle between the straight line based on the origin and the true north direction of the service satellite.

[0042] Furthermore, the signal blocking azimuth range of the access terminal is calculated based on the acquired relative position information and the azimuth of communication between the access terminal and the service satellite.

[0043] Further, when the moving azimuth of the access terminal is within the signal blocking azimuth range, it is determined that the cause of the access terminal signal abnormality is that the signal between the access terminal and the service satellite is blocked.

[0044] It should be understood that the mobile azimuth of the access terminal and the signal blocking azimuth range of the access terminal are calculated through the above steps. When the mobile azimuth of the access terminal falls within the signal blocking azimuth range, it will inevitably cause the communication signal between the access terminal and the service satellite to be blocked, thereby causing access terminal signal abnormality.

[0045] It is worth noting that the above introduction only calculates the azimuth between the access terminal and the service satellite based on the acquired first position information of the access terminal and the second position information of the service satellite. Furthermore, when the moving azimuth of the access terminal falls within the signal blocking azimuth range, it is determined that the communication signal between the access terminal and the service satellite is blocked.

[0046] Optionally, in this embodiment, the elevation angle between the access terminal and the service satellite can also be calculated based on the acquired first position information of the access terminal and the second position information of the service satellite. Accordingly, the signal blocking elevation angle range of the access terminal needs to be calculated. When the moving azimuth of the access terminal falls within the signal blocking elevation angle range, it is determined that the communication signal between the access terminal and the service satellite is blocked.

[0047] Optionally, in this embodiment, when the mobile azimuth of the access terminal falls within the signal blocking azimuth range, and / or when the mobile azimuth of the access terminal falls within the signal blocking elevation range, it is determined that the signal of communication between the access terminal and the service satellite is blocked; that is, when the mobile azimuth of the access terminal does not fall within the signal blocking azimuth range and the mobile azimuth of the access terminal does not fall within the signal blocking elevation range, it is determined that the signal of communication between the access terminal and the service satellite is not blocked, and when any one of them falls within the corresponding signal blocking range, it is determined that the signal of communication between the access terminal and the service satellite is blocked; in this way, the combination of the azimuth and the elevation makes it more accurate to determine whether the communication signal between the access terminal and the service satellite is blocked.

[0048] Then, the reason why the access terminal signal is abnormal is due to weather conditions:

[0049] In this embodiment, weather information is analyzed; optionally, the weather information is weather information of an area where the first location information of the access terminal is located.

[0050] Further, when the weather information is analyzed to be rainstorm or typhoon, it is determined that the cause of the abnormal signal of the access terminal is the weather condition.

[0051] It should be understood that the specific weather information that affects the access terminal signal needs to be set by the staff based on the test. For example, when the test obtains the weather information as foggy, it will also affect the attenuation and abnormality of the access terminal signal. When the analyzed weather information is foggy, it is determined that the cause of the abnormal access terminal signal is the weather condition.

[0052] Optionally, in this embodiment, the degree to which weather information affects the access terminal signal can also be divided. For example, when the weather information is "heavy rain above level 3 + strong wind above level 3 + lightning above level 3", it is divided into the first level, and its impact on the access terminal signal is the greatest; when the weather information is "heavy rain below level 3 + strong wind below level 3 + lightning below level 3", it is divided into the second level, and its impact on the access terminal signal is moderate; when the weather information is "cloudy and foggy", it is divided into the third level, and its impact on the access terminal signal is relatively small.

[0053] It is worth noting that this is only an example. In actual applications, staff will classify the degree to which weather information affects access terminal signals through experiments.

[0054] It should be noted that when the reasons for the abnormal access terminal signal are not due to the blocking of the communication signal between the access terminal and the service satellite and weather conditions, it is determined that the reason for the abnormal access terminal signal is that the access terminal has a fault.

[0055] In this embodiment, after analyzing the parameter information and determining the abnormal reason for the access terminal signal according to the analysis result, the method further includes: outputting the abnormal reason for the access terminal signal so that operation and maintenance staff can handle user complaints in a timely manner by checking the output abnormal reason for the access terminal signal.

[0056] Optionally, in this embodiment, when outputting the reason for the abnormal access terminal signal, corresponding information can also be output, for example: First, when it is determined that the reason for the abnormal access terminal signal is that the signal between the access terminal and the service satellite is blocked, the calculated mobile azimuth of the access terminal and the access terminal signal blocking azimuth range information can also be output accordingly, so that the staff can inform the user of the specific reason for the abnormal access terminal signal based on the information, so that the user can drive away from the current position so that the mobile azimuth of the access terminal is outside the access terminal signal blocking azimuth range, so that the access terminal signal returns to normal. Second, when it is determined that the reason for the abnormal access terminal signal is weather conditions, the degree of its impact on the access terminal signal can also be output accordingly, such as information such as large, moderate, small, etc. Third, when it is determined that the reason for the abnormal access terminal signal is a fault in the access terminal, information such as prompts to repair the access terminal or replace the access terminal can also be output accordingly.

[0057] The communication signal anomaly determination method provided in the embodiment of the present invention obtains parameter information that affects the access terminal signal when the access terminal signal is abnormal, and further analyzes the parameter information to determine the cause of the access terminal signal anomaly according to the analysis result; this solves the problem in the prior art that the cause of signal attenuation and anomaly cannot be determined, resulting in the inability to handle user complaints in a timely manner, causing certain troubles to the operation and maintenance staff. That is, the communication signal anomaly determination method provided in the embodiment of the present invention can determine the cause of signal attenuation and anomaly, so as to inform the operation and maintenance staff and handle user complaints in a timely manner, which greatly reduces the troubles of the operation and maintenance staff; and plays a very important role in network operation and maintenance optimization, system performance evaluation, etc. of satellite communication mobile carrier applications, and greatly improves the reliability of satellite communication mobile carrier applications.

[0058] Embodiment 2:

[0059] Based on the first embodiment, the embodiment of the present invention provides an example to illustrate whether the cause of the abnormal signal of the access terminal is that the communication signal between the access terminal and the service satellite is blocked.

[0060] First, see Figure 2-4 As shown, the access terminal is installed on a mobile carrier vessel, such as Figure 2 As shown in , it means that there is signal obstruction when the ship is traveling at an azimuth of 0°; Figure 3 It means that there is no signal obstruction when the ship is traveling in the direction of 10° to the left of 0° azimuth. Figure 4 It means that there is no signal obstruction when the ship is traveling in the direction of 10° to the right of 0° azimuth.

[0061] Secondly, combined Figure 5-6 When the access terminal signal is abnormal, an example is given to explain whether the abnormal reason for the access terminal signal is that the communication signal between the access terminal and the service satellite is blocked:

[0062] S601: Obtain relative position information of an access terminal and an obstruction on a mobile carrier.

[0063] like Figure 5 As shown, the access terminal is installed on the ship, and the bow is taken as the true north direction. The angle range between the access terminal and the obstruction is measured to be A∈[130°, 150°].

[0064] S602: Periodically obtain the longitude and latitude information of the access terminal, and calculate the moving azimuth of the access terminal according to the periodically obtained longitude and latitude information.

[0065] Furthermore, the "mobile azimuth" of the access terminal is calculated by the longitude and latitude information between the two cycles, which is represented by B. For example, taking the east longitude and north latitude regions as an example, the mobile azimuth B can be calculated by dividing the quadrants with the longitude and latitude positions of the previous cycle as the origin, and the following formula can be used to calculate the mobile azimuth B, assuming that the longitude and latitude of the origin of the previous cycle are L1 and E1, and the longitude and latitude of the current cycle are L2 and E2:

[0066] IF((L2-L1>0)AND(E2-E1>0)) belongs to the first quadrant:

[0067]

[0068] IF((L2-L1<0)AND(E2-E1>0)) belongs to the second quadrant:

[0069]

[0070] ELSE belongs to the third and fourth quadrants:

[0071]

[0072] Assuming L1 is 125°, E1 is 32.2°, L2 is 126°, and E2 is 32°, then B is calculated to be 101° using the above formula.

[0073] S603: Acquire the longitude information of the service satellite, and calculate the azimuth of communication between the access terminal and the service satellite according to the latest longitude and latitude information of the access terminal and the longitude information of the service satellite acquired periodically.

[0074] Further, the "azimuth of communication between the access terminal and the satellite" is calculated according to the longitude and latitude information of the access terminal and the longitude information of the service satellite, which is represented by C. Taking the east longitude and north latitude region as an example, the azimuth C of communication between the access terminal and the satellite can be calculated by the following formula, assuming that the longitude of the current cycle is L2, the latitude is E2, and the longitude of the service satellite is L3:

[0075]

[0076] Assuming L3 is 76.5°, then C is calculated to be 245.6° using the above formula.

[0077] It should be noted that S601 to S603 may be executed in any order or simultaneously, and the present invention does not impose any specific limitation on this.

[0078] S604: Calculate the signal blocking azimuth range of the access terminal according to the acquired relative position information and the azimuth of communication between the access terminal and the service satellite.

[0079] Furthermore, based on the acquired relative position information A between the access terminal and the obstruction on the mobile carrier and the azimuth C of the communication between the access terminal and the service satellite, the "signal blocking azimuth range of the access terminal" is calculated, represented by D, which is divided into the following three cases:.

[0080] If C is greater than the maximum value in the range of A: D∈[CA maximum, CA minimum];

[0081] If C is less than the minimum value in the range of A: D∈[360°+CA maximum, 360°+CA minimum];

[0082] If C is within the range of A: D∈[0°, CA minimum]D∈[360°+CA maximum, 359°];

[0083] Based on the above assumption, C is calculated to be 245.6°, so D∈[C-150°, C-130°]=[95.6°, 115.6°].

[0084] S605: Compare the movement azimuth of the access terminal and the signal blocking azimuth range of the access terminal to determine whether the communication signal between the access terminal and the service satellite is blocked.

[0085] Furthermore, the moving azimuth angle B and the signal blocking azimuth angle range D are compared. According to the above calculated moving azimuth angle B is equal to 101°, and the signal blocking azimuth angle range D∈[95.6°, 115.6°], then B∈D, and it is determined that the signal of communication between the access terminal and the service satellite is blocked. Otherwise, it is determined that the signal of communication between the access terminal and the service satellite is not blocked.

[0086] Optionally, in this embodiment, the elevation angle between the access terminal and the service satellite can also be calculated based on the acquired first position information of the access terminal and the second position information of the service satellite. Accordingly, the signal blocking elevation angle range of the access terminal needs to be calculated, wherein the calculation method is similar to that described above and will not be repeated here. When the moving azimuth of the access terminal falls within the signal blocking elevation angle range, it is determined that the communication signal between the access terminal and the service satellite is blocked.

[0087] The communication signal anomaly determination method provided by the embodiment of the present invention obtains the first position information of the access terminal, the second position information of the service satellite, and the relative position information of the obstruction on the access terminal and the mobile carrier when the access terminal signal is abnormal, and further analyzes these parameter information, and determines whether the cause of the access terminal signal anomaly is that the communication signal between the access terminal and the service satellite is blocked according to the analysis result; thereby, the operation and maintenance staff can be informed to handle the user's complaints in time, which greatly reduces the troubles of the operation and maintenance staff; and the operation and maintenance staff can also inform the user to take corresponding measures according to the determined cause of the access terminal signal anomaly caused by the blocking of the communication signal between the access terminal and the service satellite, so as to improve the access terminal signal so that the terminal signal returns to normal, which also improves the user's experience satisfaction to a certain extent.

[0088] Embodiment three:

[0089] The embodiment of the present invention is based on the first and second embodiments, and takes a specific communication signal abnormality determination process as an example for illustration, see Figure 7 shown.

[0090] S701: When the access terminal signal is abnormal, first location information of the access terminal, second location information of the service satellite, weather information, and relative location information of the access terminal and an obstruction on the mobile carrier are obtained.

[0091] S702: Calculate the moving azimuth of the access terminal and the signal blocking azimuth range of the access terminal according to the first location information, the second location information, and the relative location information.

[0092] S703: When the moving azimuth of the access terminal is within the signal blocking azimuth range of the access terminal, it is determined that the reason for the access terminal signal abnormality is that the signal between the access terminal and the service satellite is blocked.

[0093] It is worth noting that the process of determining whether the communication signal between the access terminal and the service satellite is blocked has been described in detail in the second embodiment, which will not be repeated here.

[0094] S704: Determine whether the access terminal signal is affected by the weather information according to the weather information.

[0095] S705: When the weather information is rainstorm or typhoon, it is determined that the reason for the abnormal signal of the access terminal is the weather condition.

[0096] It should be noted that S702 to S703 and S704 to S705 may be executed in any order or simultaneously, and the present invention does not make any specific limitation on this.

[0097] S706: When it is determined that the cause of the access terminal signal abnormality is not due to the blocking of the signal for communication between the access terminal and the service satellite and weather conditions, the cause of the access terminal signal abnormality is determined to be a malfunction of the access terminal.

[0098] S707: Output the reason for abnormal access terminal signal.

[0099] It should be understood that the reason for the access terminal signal abnormality may be simply due to the blocking of the communication signal between the access terminal and the service satellite, or simply due to weather conditions, or due to the blocking of the communication signal between the access terminal and the service satellite and weather conditions. In actual applications, the output can be based on the determined abnormal reason.
