One is the reason why the signal is blocked. When the access terminal is installed on a mobile carrier such as a ship or vehicle, due to the limitation of the installation carrier structure, or the unreasonable engineering installation location, there is some movement in the installation location of the access terminal.

For example, when the mast of the ship is installed because the carrier is high, the access terminal installation position and the service satellite wireless signal are blocked by the mast at some azimuth angles. Issues such as the signal difference between the access terminal and the service satellite, the decrease in system throughput, and the disconnection of the wireless link between the access terminal and the service satellite, have affected the overall network throughput of the broadband satellite communication system and the operation KPI indicators;

detailed description

In order to make the objectives, technical solutions, and advantages of the present invention clearer, the following further describes the embodiments of the present invention in detail through specific implementations in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to explain the present invention, but not to limit the present invention.

Embodiment 1: In order to solve the problem that the prior art cannot determine the cause of signal attenuation and abnormality caused by the influence, which causes the inability to process user complaints in time and causes certain troubles to the operation and maintenance staff, an embodiment of the present invention provides a problem The communication signal abnormality determination method is to obtain parameter information that affects the access terminal signal when the access terminal signal is abnormal, and further analyze the parameter information, and determine the cause of the access terminal signal abnormality according to the analysis result; see Figure 1 As shown, FIG. 1 is a schematic diagram of the basic flow of the communication signal abnormality determination method provided by this embodiment.

S101: Acquire parameter information that affects the signal of the access terminal when the signal of the access terminal is abnormal.

Optionally, in this embodiment, the signal characterization parameter information of the access terminal can be obtained to determine whether the signal of the access terminal is abnormal. For example, when the signal characterization parameter information is the signal-to-noise ratio, the current periodically obtained average signal-to-noise ratio The average signal-to-noise ratio is compared with the historical average signal-to-noise ratio. The average signal-to-noise ratio currently acquired periodically can be obtained by filtering and averaging multiple acquired signal-to-noise ratios. The historical average signal-to-noise ratio can be obtained from multiple cycles acquired The signal-to-noise ratio is filtered and averaged. When the current periodically acquired average signal-to-noise ratio is greater than or equal to the historical average signal-to-noise ratio, it indicates that the signal of the access terminal is normal. When the current periodically acquired average signal-to-noise ratio is less than the historical average signal-to-noise ratio When the signal-to-noise ratio is averaged, it indicates that the signal of the access terminal is abnormal.

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, as long as it can determine whether the access terminal signal is abnormal. The methods are all within the protection scope of the present invention, and in practical applications, flexible adjustments need to be made according to application scenarios.

Optionally, the parameter information that affects the signal of the access terminal in this embodiment includes, but is not limited to, the first location information of the access terminal, the second location information of the serving satellite, weather information, and information about the barriers on the access terminal and the mobile carrier. Relative location information, where it should be understood that the access terminal is installed on a mobile carrier.

It is worth noting that, in order to better understand the present invention, the reason for the abnormal signal of the access terminal in this embodiment is that the signal communication between the access terminal and the service satellite is blocked, the weather conditions, and the access terminal malfunctions. The present invention is not limited to these three reasons for the abnormal signal of the access terminal. In practical applications, it can be flexibly adjusted according to the specific application scenario, and at the same time, the signal that affects the access terminal obtained according to the specific reason can be adjusted flexibly. The parameter information can also be adjusted flexibly.

S102: Analyze the parameter information, and determine the reason for the abnormal signal of the access terminal according to the analysis result.

First, the reason for the abnormal signal of the access terminal is that the communication signal between the access terminal and the serving satellite is blocked.

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.

Further, the moving azimuth angle of the access terminal is calculated according to the periodically acquired first location information.

Optionally, the first location information includes latitude and longitude information, and calculating the mobile azimuth of the access terminal according to the periodically acquired first location information includes: the latitude and longitude position in the latitude and longitude information acquired in the previous period is the origin, and the current The angle between the movement direction of the latitude and longitude position relative to the origin in the latitude and longitude information obtained periodically and the true north direction.

Further, the azimuth angle of the communication between the access terminal and the serving satellite is calculated according to the latest first position information and the second position information acquired periodically.

Optionally, the first location information includes latitude and longitude information, and the second location information includes longitude information. The communication between the access terminal and the serving satellite is calculated according to the latest first location information and second location information that are periodically acquired. The azimuth angle includes: taking the latitude and longitude position in the latitude and longitude information as the origin, calculating the angle between the straight line of the service satellite based on the origin and the true north direction.

Further, the signal blocking azimuth range of the access terminal is calculated according to the acquired relative position information and the azimuth angle of communication between the access terminal and the serving satellite.

Further, when the moving azimuth of the access terminal is within the signal blocking azimuth range, it is determined that the reason for the abnormal signal of the access terminal is that the communication signal between the access terminal and the serving satellite is blocked.

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 enters the signal blocking azimuth range, it will inevitably As a result, the communication signal between the access terminal and the service satellite is blocked, causing the access terminal signal to be abnormal.

It is worth noting that the above introduction is only to calculate the azimuth angle between the access terminal and the serving satellite based on the acquired first location information of the access terminal and the second location information of the serving satellite. Further, when accessing When the mobile azimuth corner of the terminal enters the signal blocking azimuth range, it is determined that the signal of the communication between the access terminal and the serving satellite is blocked.

Optionally, in this embodiment, the elevation angle between the access terminal and the serving satellite can also be calculated according to the acquired first location information of the access terminal and the second location information of the serving satellite, and accordingly, it is also necessary to calculate the elevation angle between the access terminal and the serving satellite. The signal blocking elevation angle range of the incoming terminal, when the moving azimuth corner of the access terminal enters the signal blocking elevation angle range, it is determined that the signal communication between the access terminal and the serving satellite is blocked.

Optionally, in this embodiment, when the moving azimuth corner of the access terminal falls within the signal blocking azimuth range, and/or when the moving azimuth corner of the access terminal falls within the signal blocking elevation angle range, it is determined to be connected. The signal of the communication between the incoming terminal and the serving satellite is blocked; that is, the moving azimuth of the access terminal does not fall within the signal blocking azimuth range and the moving azimuth of the access terminal does not fall within the signal blocking elevation angle range At this time, it is judged that the communication signal between the access terminal and the service satellite is not blocked. When any one of them falls within the corresponding signal blocking range, it is judged as the signal of the communication between the access terminal and the service satellite at this time. Blocked; In this way, the combination of azimuth and elevation makes the determination of whether the communication signal between the access terminal and the serving satellite is blocked more accurately.

Then, the reason for the abnormal signal of the access terminal is explained by the weather condition.

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

Further, when it is analyzed that 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.

It should be understood that the specific weather information that affects the signal of the access terminal needs to be set by the staff according to the experiment. For example, when the weather information obtained by the experiment is cloud and fog, it will also affect the signal attenuation and abnormality of the access terminal. When the weather information of is cloud and fog, it is determined that the reason for the abnormal signal of the access terminal is the weather condition.

Optionally, in this embodiment, the degree to which the weather information affects the signal of the access terminal can also be divided. For example, when the weather information is "storm level 3 or higher + gale level 3 or higher + lightning level 3 or higher", it is classified as the first The first level has the greatest impact on the access terminal signal; when the weather information is "stormy rain below level 3 + gale below level 3 + lightning level below level 3", it is classified as the second level, which has the greatest impact on the access terminal signal The degree of influence is moderate; when the weather information is "clouds and fog", it is classified as the third level, and its degree of influence on the signal of the access terminal is small.

It is worth noting that this is only an example. In practical applications, the staff will divide the degree to which the weather information affects the signal of the access terminal after experimentation.

It should be noted that when the reason for the abnormal signal of the access terminal does not belong to the signal blocking and weather conditions between the access terminal and the serving satellite, it is determined that the reason for the abnormal signal of the access terminal is the failure of the access terminal.

In this embodiment, the parameter information is analyzed, and after the reason for the abnormal signal of the access terminal is determined according to the analysis result, it also includes: outputting the reason for the abnormal signal of the access terminal, so that the operation and maintenance staff can view the reason for the abnormal signal of the access terminal. Deal with user complaints in a timely manner.

Optionally, in this embodiment, when the reason for the abnormal signal of the access terminal is output, corresponding information can also be output, for example: 1. When it is determined that the reason for the abnormal signal of the access terminal is that the signal communicated between the access terminal and the service satellite is blocked When blocking, the calculated moving azimuth of the access terminal and the signal blocking azimuth range information of the access terminal can also be output correspondingly, so that the staff can inform the user of the specific reason for the abnormal signal of the access terminal based on the information, so that the user By moving away from the current position, the moving azimuth of the access terminal is outside the signal blocking azimuth range of the access terminal, so that the signal of the access terminal is restored to normal. Second, when it is determined that the reason for the abnormal signal of the access terminal is weather conditions, it can also correspondingly output the degree of its influence on the signal of the access terminal, such as information such as large, moderate, and small impact. 3. When it is determined that the reason for the abnormal signal of the access terminal is that the access terminal is faulty, it can also output corresponding information such as repairing the access terminal or replacing the access terminal.

Assuming that L3 is 76.5°, then C is equal to 245.6° calculated by the above formula.

S605: Compare the mobile azimuth of the access terminal with the signal blocking azimuth range of the access terminal, and determine whether the signal communicated between the access terminal and the serving satellite is blocked.

Further, compare the moving azimuth angle B and the signal blocking azimuth angle range D, the moving azimuth angle B calculated above is equal to 101°, and the signal blocking azimuth angle range D ∈ [95.6°, 115.6°] range, then B ∈ D. It is determined that the communication signal between the access terminal and the service satellite is blocked, otherwise, it is determined that the communication signal between the access terminal and the service satellite is not blocked.

Optionally, in this embodiment, the elevation angle between the access terminal and the serving satellite can also be calculated according to the acquired first location information of the access terminal and the second location information of the serving satellite, and accordingly, it is also necessary to calculate the elevation angle between the access terminal and the serving satellite. The signal blocking elevation angle range of the incoming terminal, the calculation method is similar to the above, and will not be repeated here. When the mobile azimuth corner of the access terminal enters the signal blocking elevation angle range, it is determined that the signal communicated between the access terminal and the serving satellite is blocked.
