Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

The embodiment of the present invention provides an information processing solution, which can determine the first transmission quality parameter and the second transmission quality parameter according to the signal received by the first device, and further, predict the first device and the second transmission quality parameter according to the first transmission quality parameter.

In addition, the prompt message may also include the reason why the communication connection is about to be disconnected. According to the reason included in the prompt message, a corresponding control scheme can be adopted to control the operation of the first device to avoid the disconnection of the communication connection, thereby reducing the disconnection of the communication connection.

Based on the foregoing information processing system, an embodiment of the present invention provides an information processing method. Referring to FIG. 2, which is a schematic flowchart of an information processing method according to an embodiment of the present invention, the information processing method shown in FIG. 2 can be applied to a first device, and a communication connection is established between the first device and the second device. , The first device and the second device may transmit signals to each other based on the communication connection. The information processing method described in FIG. 2 may be executed by the first device, and specifically may be executed by the processor of the first device. The following steps are shown in FIG. 2:

Step S201: Determine the first transmission quality parameter and the second transmission quality parameter according to the signal received by the first device.

The signal received by the first device may include the signal sent by the second device, and the signal received by the first device may also include interference signals or noise from other devices. Optionally, the first device may include a movable platform such as a drone or a robot, and the second device may include a control device corresponding to the first device, such as a remote controller of the movable platform. Alternatively, the second device may include a movable platform, and the first device includes a control device corresponding to the first device.

In an embodiment, the first transmission quality parameter may include any one or more of the following: Packet Error Rate (PER) and Carrier to Interference and Noise Ratio (CINR); The second transmission quality parameter may include any one or more of the following: Received Signal Strength Indicator (RSSI) and Reference Signal Received Power (RSRP).

It should be understood that the signal received by the first device may include effective signals and noise signals (the noise floor and interference signals from other devices are collectively referred to as noise signals), and the packet error rate PER can be understood as all data packets included in the received signal The proportion of data packets in which errors occur, the reference signal power RSRP can be understood as the received power of the effective signal, and the signal received strength indicator RSSI can be understood as the strength of the received signal including the effective signal and the noise signal. The carrier interference noise The ratio CINR can be understood as the ratio of the effective signal received power to the noise signal received power.

In one embodiment, the determining the first transmission quality parameter and the second transmission quality parameter according to the signal received by the first device includes: using baseband information identification technology to perform baseband information processing on the signal received by the first device to obtain the first transmission quality parameter. A transmission quality parameter and a second transmission quality parameter.

Step S202: Predict whether the communication connection between the first device and the second device is about to be disconnected according to the first transmission quality parameter.

It should be understood that the first device and the second device transmit signals based on the communication connection between the first device and the second device. For example, the first device is a drone, and the second device is a control device. The second device can send a control signal to the first device based on the communication connection between the two, such as a signal to control the flight of the second device; similarly, The first device may send a real-time image transmission signal of the drone to the second device based on the communication connection between the two. If the communication connection between the first device and the second device is disconnected, the first device cannot receive the control signal, and the second device cannot receive the real-time image transmission signal, which may easily affect flight safety. Therefore, in order to ensure the safe operation of the device, the embodiment of the present invention can predict whether the communication connection is about to be disconnected according to the first transmission quality parameter. Relief plan, or remind the user of the first device or the second device to take relief measures, thereby reducing the probability of communication disconnection and ensuring the safe operation of the device.

In an embodiment, the first transmission quality parameter includes a packet error rate PER, and the predicting whether the communication connection between the first device and the second device is about to be disconnected according to the first transmission quality parameter includes: according to the target time The packet error rate set within predicts whether the communication connection between the first device and the second device is about to be disconnected. Wherein, the target time can be any time period designated by the first device.

As an optional embodiment, the predicting whether the communication connection between the first device and the second device is about to be disconnected according to the packet error rate set within the target time includes: obtaining the error Among the multiple packet error rates included in the packet rate set, the first number of packet error rates that are greater than the packet error rate threshold; if the first number is greater than or equal to the first number threshold, predict that the first device and the The communication connection between the second device is about to be disconnected.

Wherein, the first number threshold may be determined by the proportion of the packet error rate that is greater than the packet error rate threshold in the set of tolerable packet error rates in the case of a communication connection. Assuming that the proportion of the packet error rate that is greater than the packet error rate threshold in the preset packet error rate set is 70%, it is predicted that the communication connection between the first device and the second device is about to be disconnected. The first number threshold can be determined according to the total number of packet error rates included in the packet error rate set and the percentage of 70% of the packet error rates that are greater than the packet error rate threshold. For example, if the total number of packet error rates included in the packet error rate set is 100, the first number threshold may be 100*70%=70.

Optionally, for different transmission services, the tolerable packet error rate is different. Therefore, according to different transmission services, the packet error rate threshold is also different.

Optionally, the packet error rate greater than the packet error rate threshold may be a packet error rate at a continuous time, or may not be a packet error rate generated at a continuous time. For example, there are 5 packet error rates in the packet error rate set, which are PER1, PER2, PER3, PER4, and PER5 in the order in which the packet error rate occurs. Assume that the first number of packet error rates greater than the packet error rate threshold is 3 One, the three packet error rates may be consecutive time packet error rates such as PER1, PER2, PER3; or, these three packet error rates may not be consecutive time packet error rates such as PER2, PER4, and PER5.

As another optional embodiment, the predicting whether the communication connection between the first device and the second device is about to be disconnected according to the packet error rate set within the target time includes: The multiple packet error rates included in the packet error rate set are differentiated to obtain the increase rate of the packet error rate within the target time; if the increase rate of the packet error rate is greater than or equal to the first speed threshold, the prediction is The communication connection between the first device and the second device is about to be disconnected. Wherein, the first speed threshold may be preset, and the first speed threshold may be related to the environment in which the first device and the second device are located, and the communication channel conditions between the first device and the second device. The embodiments of the invention are not described in detail.

Optionally, the differential processing of multiple packet error rates included in the packet error rate set may refer to first-order differential processing or second-order differential processing. In specific implementation: divide the target time into multiple time periods For example, the target time is t, and t is divided into multiple time periods of equal length Δt ₁ , Δt ₂ , Δt ₃ and so on. How many time periods are divided into can be set according to actual needs, which is not limited in the embodiment of the present invention; Calculate the average value of PER in each time period (or filter value similar to the average process); if there are n pairwise adjacent time periods, the average value of n PERs can be expressed as y ₃ =ΔPER{n }; _{Carry out second-order differential processing on y 3} =ΔPER{n} to obtain the increase rate of packet error rate within the target time.

Step S203: If the communication connection is about to be disconnected, output a prompt message indicating that the communication connection is about to be disconnected, and the prompt message carries the reason why the communication connection is about to be disconnected.

It should be understood that when it is determined that the communication connection is about to be disconnected, a prompt message carrying the reason for the upcoming disconnection is output, so that a relief solution can be initiated according to the reason in the prompt message to avoid the disconnection of the communication connection. For example, the first device is a movable platform and the second device is a control device. If it is predicted through the above step S202 that the communication connection between the first device and the second device is about to be disconnected, the first device can be based on the upcoming disconnection of the communication connection. The reason for opening controls the movable platform to perform deceleration, ascent, hovering or returning to the original route.

In an embodiment, the reason why the communication connection is about to be disconnected in the prompt message may be determined according to the second transmission quality parameter described in step S201. Optionally, the second transmission quality parameter includes the reference signal received power, and the method further includes: determining the reason for the upcoming disconnection of the communication connection according to the reference signal received power set within the target time.

In a specific implementation, the determining the reason that the communication connection is about to be disconnected according to the reference signal received power set within the target time includes: performing differentiation processing on multiple reference signal received powers included in the reference signal received power set to obtain The first rate of change of the received power of the reference signal within the target time; compare the first rate of change with the theoretical value of the first rate of change, and obtain the first rate of change and the first rate of change A first difference between theoretical values of the rate of change; if the first rate of change is less than the theoretical value of the first rate of change, and the first difference is greater than a first difference threshold, the communication is determined The reason that the connection is about to be disconnected is that the communication link is blocked.

Wherein, the theoretical value of the first rate of change is calculated on the assumption that the communication link between the first device and the second device is a free space transmission link model condition. The transmission link model of the free space refers to a large wireless space filled with a uniform, linear isotropic ideal medium, which is an ideal situation. Propagation in free space without any attenuation and without any obstruction. In specific implementation, the implementation manner of calculating the theoretical value of the first rate of change may include: real-time calculation of the first device and the second device through the Global Positioning System (GPS) or Round-Trip Time (RTT) The relative distance information between the devices; the height information of the first device is calculated in real time through GPS; the transmission power of the signal transmitted by the second device and the antenna reception gain of the first device are obtained; based on the above-mentioned relative distance information, height information, transmission power and The antenna receiving gain of the first device is calculated as the theoretical value of the first rate of change in free space. It should be noted that the theoretical value of the first rate of change can also be calculated based on other transmission link models, and those skilled in the art can select the corresponding transmission link model according to actual application scenarios, for example, it can also be a terrestrial bi-radio propagation link. Model.

In an embodiment, the differential processing of multiple reference signal received powers included in the reference signal received power set may refer to first-order differential processing. In specific implementation, the implementation manner of performing differentiation processing on the multiple reference signal received powers included in the reference signal received power set to obtain the first rate of change of the reference signal received power within the target time may include: The target time is divided into multiple time periods, for example, the target time is t, and t is divided into multiple time periods of equal length Δt ₁ , Δt ₂ , Δt _3, etc., and the value of each time period can be 10 ms -1000ms; Calculate the average value of RSRP in each time period (or filter value similar to the average process); if there are n pairwise adjacent time periods, the average value of n RSRP can be expressed as y ₁ = ΔRSRP{n}; _{Carry out first-order differential processing on y 1} =ΔRSRP{n} to obtain the first rate of change within the target time.

Assuming that y ₁ =ΔRSRP{n} is the result of the first-order differential processing, that is, the first rate of change can be expressed as y′ ₁ , the theoretical value of the first rate of change is expressed as Y′ ₁ , and the first difference threshold is expressed as For TL _rsrp . Comparing y′ ₁ with Y′ ₁ , if y′ ₁ <Y′ ₁ and |y′ ₁ -Y′ ₁ |>TL _rsrp , it can be determined that the reason for the communication connection to be disconnected is being blocked. Referring to FIG. 3, it is a schematic diagram of the reference signal received power change with time when obstructed according to an embodiment of the present invention. In FIG. 3, 301 represents a schematic diagram of the theoretical reference signal received power change during the target time, and 302 represents the change of the theoretical reference signal received power at the target time. The schematic diagram of the change of the received power of the reference signal obtained by the actual measurement in FIG. 3 shows that within the target time t, the first rate of change is less than the theoretical value of the first rate of change.

In one embodiment, the first difference threshold can be determined with reference to the attenuation coefficients of different materials, or it can be obtained through training with different shielding materials in advance. For example, the types of common shielding objects can include plants, concrete buildings, wooden buildings, and metal. Any one or more of buildings, human bodies, and plastic objects. Set corresponding first difference thresholds for different types of obstructions, so that the first device determines the type of obstruction that will cause the communication connection to be disconnected according to the relationship between the first difference and the first difference threshold, such as the first difference A difference threshold is set for the human body with reference to the obstruction. When the first difference is less than the first difference threshold, it indicates that the communication connection between the first device and the second device is affected by the obstruction, and the type of the obstruction is a human body. Therefore, when the communication link is about to be disconnected because the communication link is blocked, the prompt information in step S103 may also include the type of the blocking object. The type of the blocking object may include a human body, a plant, or a building. The buildings may include any one or more of concrete buildings, wooden buildings, and metal buildings.

In one embodiment, the step of determining the reason for the communication connection to be disconnected according to the second transmission quality parameter may be synchronized with the step of predicting whether the communication connection between the first device and the second device is about to be disconnected according to the first transmission quality parameter Execute, if it is predicted that the communication connection is about to be disconnected, output the reason why the communication connection is about to be disconnected.

In other embodiments, the step of determining the reason that the communication connection is about to be disconnected according to the second transmission quality parameter may also be performed after predicting that the communication connection between the first device and the second device is about to be disconnected according to the first transmission quality; Or, determining the reason for the upcoming disconnection of the communication connection can be performed before predicting whether the communication connection is about to be disconnected, and when it is predicted that the communication connection is about to be disconnected, the reason for the upcoming disconnection of the communication connection is carried in the prompt message for output.

Based on the foregoing information processing method, an embodiment of the present invention also provides another information processing method. Refer to FIG. 4, which is a schematic flowchart of another information processing method provided by an embodiment of the present invention. The information processing method shown in FIG. 4 is applied to a first device, and a communication connection is established between the first device and the second device, and the first device and the second device can transmit signals to each other based on the communication connection. The information processing method described in FIG. 4 may be executed by a first device, and specifically may be executed by a processor of the first device. The information processing method shown in FIG. 4 may include the following steps:

Step S501: Determine a first transmission quality parameter and a second transmission quality parameter according to the signal received by the first device.

In an embodiment, for some feasible implementation manners included in step S501, reference may be made to the description of the relevant steps in the embodiment shown in FIG. 2, which will not be repeated here.

Step S502: Predict whether the communication connection between the first device and the second device is about to be disconnected according to the first transmission quality parameter.

In an embodiment, the first transmission quality parameter may include a carrier-to-interference and noise ratio (CINR), and predicting whether the communication connection between the first device and the second device is about to be disconnected according to the first transmission quality parameter includes: The carrier-to-interference-to-noise ratio set within the target time predicts whether the communication connection between the first device and the second device is about to be disconnected.

As an optional embodiment, the predicting whether the communication connection between the first device and the second device is about to be disconnected according to the set of carrier-to-interference and noise ratios within the target time includes: obtaining the The carrier-to-interference-to-noise ratio set includes the second number of the carrier-to-interference-to-noise ratio that is less than the ratio threshold; if the second number is greater than or equal to the second number threshold, predict that the first device and The communication connection between the second device is about to be disconnected.

Wherein, the second quantity threshold may be determined according to the proportion of carrier interference noise that is less than the carrier interference noise ratio threshold in the tolerable carrier interference noise ratio set when the communication connection is kept connected. Assuming that the proportion of the carrier-to-interference-to-noise ratio that is less than the carrier-to-interference noise threshold in the preset carrier-to-noise ratio set is w%, it is predicted that the communication connection between the first device and the second device is about to be disconnected. The second number threshold can be determined according to the total number of carrier-to-interference-to-noise ratios included in the carrier-to-interference-to-noise ratio set and the percentage of carrier-to-interference-to-noise ratio w% greater than the carrier-to-interference-to-noise ratio. For example, w=60, carrier-to-interference-to-noise ratio set The total number of all carrier-to-interference and noise ratios included in is 100, and the second number threshold may be 60%*100=60.

Optionally, the carrier-to-interference-to-noise ratio that is less than the threshold value of the carrier-to-interference-to-noise ratio may be a carrier-to-interference-to-noise ratio generated at a continuous time, or may not be a carrier-to-interference to noise ratio generated at a continuous time. For example, the carrier-to-interference-to-noise ratio set includes 5 carrier-to-interference-noise ratios, which are CINR1, CINR2, CINR3, CINR4, and CINR5 in the order of the time the carrier-to-interference-noise ratio is generated. The second number is three, and the three carrier-to-interference and noise ratios may be continuous time, such as CINR1, CINR2, and CINR3; or, the three carrier-to-interference and noise ratios may not be continuous time, such as CINR2, CINR4, and CINR5.

As another optional implementation manner, the predicting whether the communication connection between the first device and the second device is about to be disconnected according to the set of carrier-to-interference and noise ratios within the target time includes: The multiple carrier-to-interference-to-noise ratios included in the set are differentiated to obtain the carrier-to-interference-to-noise ratio reduction speed within the target time; if the carrier-to-interference-to-noise ratio reduction speed is greater than or equal to the second speed threshold, predict The communication connection between the first device and the second device is about to be disconnected. Wherein, the second speed threshold may be preset, and the second speed threshold may be related to the environment in which the first device and the second device are located, and the communication channel conditions between the first device and the second device. The embodiments of the invention are not described in detail.

Optionally, the differential processing of multiple carrier-to-interference-to-noise ratios included in the carrier-to-interference-to-noise ratio set includes second-order differential processing. In specific implementation, the target time is divided into multiple time periods, for example, the target time is t , Divide t into multiple time periods of equal length Δt ₁ , Δt ₂ , Δt ₃ and so on. How many time periods are divided into can be set according to actual needs, which is not limited in the embodiment of the present invention; the calculation is performed in each time period The average value of the internal CINR (or the filtering value similar to the average process); if there are n pairwise adjacent time periods, the average value of n CINRs can be expressed as y ₂ =ΔCINR{n}; for y ₂ = ΔCINR{n} performs second-order differential processing to obtain the carrier-to-interference-to-noise ratio reduction speed within the target time.

It can be seen from the description in the embodiment in FIG. 2 that the quality of the first transmission parameter may also include the packet error rate. In other embodiments, in the embodiment of the present invention, multiple packet error rates in the set of packet error rates within the target time may be calculated. PER performs first-order differential processing to obtain the rate of change of PER; performs first-order differential processing on multiple carrier-to-interference-to-noise ratios included in the set of carrier-to-interference and noise ratios to obtain the rate of change of CINR, which is based on the rate of change of PER and the rate of change of CINR The change rate can obtain the change trend of PER and CINR respectively, and predict whether the communication connection between the first device and the second device is about to be disconnected according to the change trend of PER and/or the change trend of CINR. For example, if the PER is predicted to continue to increase according to the rate of change of PER, or if the rate of change of CINR predicts that the CINR is in a trend that first decreases and then stabilizes, the communication connection between the first device and the second device can be predicted About to be disconnected.

For example, referring to FIG. 5, it is a schematic diagram of the carrier-to-interference and noise ratio and the packet error rate variation with time according to an embodiment of the present invention. In FIG. 5, 501 represents the variation curve of PER, and 502 represents the variation curve of CINR. It can be seen from 5 that the PER is gradually increasing, and the CINR is gradually decreasing and tending to stabilize. It can be predicted that the communication connection between the first device and the second device may be about to be disconnected.

Step S503: If the communication connection is about to be disconnected, a notification message is output, and the notification message includes a check control for checking the disconnection reason.

In one embodiment, after the first device determines that the communication connection between the first device and the second device is about to be disconnected, it may output a notification message that the communication connection is about to be disconnected to inform that the communication connection is about to be disconnected.

Optionally, the notification information may also include viewing controls for viewing the disconnection reason, such as the "View Reason" option. If the user also checks the disconnection reason, it is easier to control the operation of the first device or the second device according to the disconnection reason. Then the viewing control can be triggered so that the first device executes step S504. If the user does not want to check the reason for the disconnection, the first device may not perform step S504. In this way, part of the power consumption of the first device can be saved. For example, if the user has already planned to stop the operation of the first device and the second device at this time, he can ignore the notification information.
