The inventor finds that the existing high-altitude platform base station can constantly perform actions such as translation, lifting, pitching, rotation, rolling and the like due to air currents and the like, so that the coverage area of the high-altitude platform base station is changed, and the situation that a call is dropped due to no signal coverage of terminal equipment connected with the high-altitude platform base station can be caused. However, in the currently and generally used method for processing coverage loss of the terminal device, signal recovery is generally performed after no signal coverage exists in an area where the terminal is located, so that the terminal device is disconnected from the high-altitude base station and drops a call, and the terminal device cannot transmit service data.
In order to solve the above problems, in the embodiment of the present application, attitude data of a high-altitude base station and environment information of an environment where the high-altitude base station is located are obtained; predicting target terminal equipment which is to lose coverage after preset time based on the attitude data and the environment information; and controlling the target terminal equipment to establish a D2D link with the high-altitude base station so that the target terminal equipment interacts with the high-altitude base station through a D2D link. According to the method and the device, the target terminal equipment which is covered is lost after the preset time is predicted by obtaining the attitude data and the environmental information of the high-altitude base station, and the target terminal equipment is immediately controlled to establish a D2D link with the high-altitude base station after the target terminal equipment is predicted, so that the situation that the call is dropped due to no signal coverage of the terminal caused by the movement of the high-altitude base station can be prevented, and the stability of terminal service can be guaranteed.
The following further describes the content of the application by describing the embodiments with reference to the attached drawings.
The embodiment provides a processing method for preventing a terminal from losing coverage by a high-altitude base station, as shown in fig. 1, the method includes:
and S10, acquiring attitude data of the high-altitude base station and environment information of the environment where the high-altitude base station is located.
Specifically, the high-altitude base station may be arranged on a high-altitude platform (e.g., a floating platform), and the high-altitude base station may be driven by the high-altitude platform to move so as to change a coverage area of the high-altitude base station, where actions affecting the coverage area of the high-altitude base station in the movement of the high-altitude platform mainly include high-altitude platform lateral movement, high-altitude platform pitching, high-altitude platform rotation, high-altitude platform lifting, and high-altitude platform rolling. For example, as shown in fig. 2, when the high-altitude platform moves in the horizontal direction, the coverage area of the high-altitude base station moves correspondingly; as shown in fig. 3, when the high-altitude platform moves in the vertical direction, the coverage area of the high-altitude base station is correspondingly reduced; as shown in fig. 4, when the high altitude platform is pitched down, the coverage area of the high altitude base station is correspondingly reduced.
The attitude data of the high-altitude base station may include a horizontal wave width, a vertical wave width, a base station height, an included angle between a beam direction and a vertical direction, and an included angle between a horizontal beam center and a vertical direction. The environment information is high altitude environment information of a high altitude where the high altitude base station is located, wherein the environment information may include a wind speed of a position where the high altitude base station is located, a wind direction of the position where the high altitude base station is located, and the like.
In addition, the high altitude base station is preconfigured with initial attitude data, and during movement of the high altitude base station with the high altitude platform, the attitude data of the high altitude base station may be determined based on the initial attitude data and the attitude data of the high altitude platform. Therefore, in an implementation manner of this embodiment, the acquiring attitude data of the high-altitude base station may specifically be acquiring platform attitude data of a high-altitude platform on which the high-altitude base station is arranged, and then determining attitude data of the high-altitude base station according to the acquired platform attitude data, where the platform attitude data may include information such as a platform translation speed, a platform translation speed direction, a platform pitch angle, a platform lifting speed, a platform rotation angle, a platform rotation angular velocity, and a platform roll angle.
S20, predicting target terminal equipment losing coverage after preset time based on the attitude data and the environment information, wherein the target terminal is interacted with the high-altitude base station.
Specifically, the preset time may be preset, and it can be understood that after the attitude data and the environment information are obtained, the coverage area of the high-altitude base station after the preset time is predicted based on the obtained attitude data and the obtained environment information, so as to predict whether there is a target terminal device about to lose coverage, and establish a standby connection for the target terminal device in advance, so as to avoid a hang-up phenomenon occurring after the preset time due to the loss of coverage of the target terminal device.
In an implementation manner of this embodiment, the preset time may also be determined according to the ambient wind speed obtained from the environmental information, for example, the preset time may be inversely proportional to the ambient wind speed, and when the ambient wind speed is high, the preset time is short; on the contrary, when the ambient wind speed is small, the preset time is long, so that the prediction frequency can be optimized on one hand, and the area difference between the prediction coverage area of the high-altitude base station and the current coverage area of the high-altitude base station can be ensured to be consistent on the other hand, thereby avoiding the phenomenon that D2D link establishment of partial target terminal equipment fails due to the fact that a large number of target terminal equipment needs to establish D2D link due to the area difference between the prediction coverage area of the high-altitude base station and the current coverage area of the high-altitude base station.
In an implementation manner of this embodiment, the predicting, based on the posture data and the environment information, a target terminal device that will lose coverage within a preset time specifically includes:
determining a current coverage area of the high-altitude base station based on the attitude data;
when the current coverage area and the previous coverage area meet preset conditions, predicting a predicted coverage area corresponding to the high-altitude base station after preset time according to the environment information;
and predicting the target terminal equipment which loses coverage after the preset time according to the predicted coverage area.
Specifically, the current coverage area is determined according to the attitude data acquired at the current acquisition time, and the previous coverage area is determined according to the attitude data acquired at the previous acquisition time of the current time. It can be understood that in the process of the high-altitude base station, the attitude data of the high-altitude base station is acquired periodically or at a plurality of preset moments, and the coverage area corresponding to the attitude data is determined for each acquired attitude data of the high-altitude base station, so as to determine the target terminal device which will lose coverage after a preset time. The current acquisition time of the attitude data corresponding to the current coverage area and the previous acquisition time corresponding to the previous coverage area are two adjacent acquisition times, and the previous acquisition time is positioned before the current acquisition time. In a specific implementation manner, in the process of the high altitude base station, the attitude data of the high altitude base station is acquired at predetermined intervals, wherein the predetermined time may be preset, for example, 1 minute, 2 minutes, and the like.
In one implementation manner of this embodiment, as shown in fig. 5, the high altitude base station may be an array antenna, the array antenna beam is directed to a preset direction, and the array antenna beam has a horizontal wave width and a vertical wave width in a horizontal direction and a vertical direction, respectively, for example, the beam shape of the array antenna beam is a beam shape as shown in fig. 6, where the horizontal wave width of the horizontal direction beam of the array antenna beam is B, and the vertical wave width of the vertical direction beam of the array antenna beam a is a.
Based on this, when the array antenna beam is projected onto a plane (e.g., ground or water surface, etc.), the area shape of the coverage area formed by the array antenna projected on the plane can be determined according to the height of the array antenna and the direction of the array antenna beam. For example, when the antenna patterns of the array antenna are uniformly distributed, as shown in fig. 7, the coverage area formed by the planar projection of the array antenna has an elliptical shape, and then the calculation formula of the coverage area formed by the planar projection of the array antenna may be:
m＝h*[tan(A+C)-tan(C)]
wherein m is the transverse width of the coverage range, n is the longitudinal width of the coverage range, B is the horizontal wave width, A is the vertical wave width, H is the height of the base station, C is the included angle between the beam direction and the vertical direction, and D is the included angle between the center of the horizontal beam and the vertical direction.
The preset condition may be preset and is used to determine whether there is a basis for the target terminal device to lose coverage after the preset time needs to be predicted. The preset condition may include a first condition and a second condition, where the first condition is that a distance between an area center point of a current coverage area and an area center point of a previous coverage area is greater than a preset distance threshold; the second condition is that the area of the current coverage area is smaller than the area of the previous coverage area, and the area difference between the area of the previous coverage area and the area of the current coverage area is larger than a preset area threshold. The current coverage area and the previous coverage area satisfy the preset condition means that the current coverage area and the previous coverage area satisfy at least one of a first condition and a second condition, for example, if the current coverage area and the previous coverage area satisfy the first condition, the previous coverage area and the previous coverage area satisfy the preset condition; or if the current coverage area and the previous coverage area meet the second condition, the previous coverage area and the previous coverage area meet the preset condition; or, if the current coverage area and the previous coverage area satisfy the first condition and the second condition, the previous coverage area and the previous coverage area satisfy the preset condition.
In one implementation of this embodiment, the environmental information includes an ambient wind speed and an ambient wind direction; when the current coverage area and the previous coverage area meet a preset condition, predicting the corresponding predicted coverage area of the high-altitude base station after a preset time according to the environment information specifically comprises:
when the current coverage area and the previous coverage area meet preset conditions, determining the change size and the change direction of the coverage area of the high-altitude base station according to the previous coverage area and the current coverage area;
determining the change speed corresponding to the high-altitude base station according to the change size and the interval time between the current coverage area and the previous coverage area;
and predicting a predicted coverage area corresponding to the high-altitude base station after a preset time based on the environment wind speed, the environment wind direction, the change speed and the change direction.
Specifically, the change distance is a change size of a current coverage area of the high-altitude base station relative to a previous coverage area, where the change size includes a movement distance of the current coverage area relative to the previous coverage area and a reduced size of the current coverage area relative to the previous coverage area; the direction of change refers to the direction of movement of the current coverage area relative to the previous coverage area. The moving distance can be determined based on a region position corresponding to a previous coverage region and a region position corresponding to a current coverage region, and the reduction size can be determined based on a region area of the previous coverage region and a region area of the current coverage region; the moving direction is the direction information of the current coverage area relative to the previous coverage area.
Further, after the change size and the change direction of the coverage area of the high-altitude base station are obtained and determined, the change speed of the high-altitude base station can be determined according to the time interval between the acquisition time corresponding to the current coverage area and the acquisition time corresponding to the previous coverage area. And finally, assuming that the high-altitude platform changes at a constant speed along the change direction according to the change speed, predicting the predicted coverage area after preset time. However, in a high-altitude environment, the ambient wind speed and the ambient wind direction may change, so that after the change speed and the change direction are determined, the ambient wind speed variation and the ambient wind direction variation are determined based on the ambient wind speed and the ambient wind direction, and the ambient wind speed and the ambient wind direction corresponding to a previous coverage area, finally, the change speed and the change direction of the high-altitude base station are adjusted according to the ambient wind speed variation and the ambient wind direction variation, the variation of the predicted coverage area relative to the current coverage area after the preset time is predicted based on the adjusted change speed and the adjusted change direction, and the predicted coverage area is determined based on the variation and the current coverage area.
In one implementation manner of this embodiment, the target terminal device is located in the current coverage area and is not located in the predicted coverage area, where the high-altitude base station stores in advance location information of each terminal device in its coverage area. After the predicted coverage area is obtained, the terminal devices in the predicted coverage area and the target terminal devices not in the predicted coverage area can be determined based on the position information of each terminal device in the current coverage area and the area position information of the preset coverage area, so that the target terminal devices which are lost in coverage after the predicted time is obtained are predicted. In addition, in practical application, when the covered target terminal equipment is lost after the preset time is predicted, the channel quality of each terminal equipment in the current covered area can be obtained, the terminal equipment with the channel quality smaller than the quality threshold value is selected, and the selected terminal equipment is also used as the target terminal equipment, so that the phenomenon of hanging up the call of the terminal equipment due to the poor base station signal area of the high-altitude base station covered area where the terminal equipment is located can be avoided.
And S30, controlling the target terminal equipment to establish a D2D link with the high-altitude base station, so that the target terminal equipment interacts with the high-altitude base station through the D2D link.
Specifically, the D2D link is a target terminal device interacting with a base station through a D2D terminal. The other terminal devices are recorded as D2D terminals, the distance between the D2D terminal and the target terminal device is less than a preset distance threshold, and the channel quality of the D2D terminal reaches a preset channel quality threshold. For example, after the preset time is predicted, N target terminal devices losing the coverage area are set, where the N target terminal devices are { E1, E2, E3 … En … En }, then each target terminal device selects a corresponding D2D terminal, assuming that the selected D2D terminal is { F1, F2, F3 … Fn … Fn }, and that each D2D terminal is located in the predicted coverage area of the high-altitude base station and has a channel quality greater than a preset channel quality threshold with the high-altitude base station, then a D2D link is established for each target terminal device and the corresponding D2D terminal { En, Fn } in a fast configuration manner, and corresponding wireless link resources are configured; after the { En, Fn } terminal establishes a D2D link, the target terminal device En may perform signaling and service interaction with the high-altitude base station through its corresponding D2D terminal Fn.
In one mode of this embodiment, the D2D terminal may be a terminal device in a predicted coverage area corresponding to the high-altitude base station, and the D2D terminal device interacts with the high-altitude base station; alternatively, the D2D terminals may be located in the coverage area of high altitude base stations adjacent to the high altitude base station, and the D2D terminal devices interact with the adjacent high altitude base station.
Based on this, the controlling the target terminal device to establish a D2D link with the high altitude base station, so that the interaction between the target terminal device and the high altitude base station through the D2D link specifically includes:
determining a D2D terminal corresponding to the target terminal device, wherein the D2D terminal is located in a predicted coverage area corresponding to the high-altitude base station;
when the D2D terminal is determined, controlling the target terminal equipment to establish a D2D link with the D2D terminal, and configuring wireless link resources for the D2D link so that the target terminal equipment interacts with the high-altitude base station through the D2D terminal.
When the D2D terminal is not determined, detecting whether a D2D terminal exists in a neighboring high-altitude base station corresponding to the high-altitude base station; and if the D2D terminal exists in the adjacent high-altitude base station, controlling the target terminal equipment to establish a D2D link with the D2D terminal, and configuring wireless link resources for the D2D link so that the target terminal equipment interacts with the adjacent high-altitude base station through the D2D terminal.
Specifically, the determining of the D2D terminal corresponding to the target terminal device means that the distance between the selected D2D terminal and the target terminal device in the predicted coverage area is less than a preset distance threshold, and the channel quality of the D2D terminal reaches a preset channel quality threshold. In an implementation manner of this embodiment, when determining the D2D terminal, the high-altitude base station and an adjacent high-altitude base station corresponding to the high-altitude base station may also be searched simultaneously, and when one D2D terminal exists in the high-altitude base station and the adjacent high-altitude base station, the target terminal device is directly controlled to establish a D2D link with the D2D terminal; when a plurality of (including 2) D2D terminals exist in the high-altitude base station and the adjacent high-altitude base station, one D2D terminal may be randomly selected, and the target terminal device may be controlled to establish a D2D link with the selected D2D terminal, or the target terminal device and the adjacent high-altitude base station may be sequentially selected from the high-altitude base station to the adjacent high-altitude base station, or the target terminal device and the target terminal device may be sequentially selected from a small distance to a large distance, or the D2D device may be sequentially selected from a good channel quality to a bad channel quality, and so on.
In addition, in practical application, after the target terminal equipment is obtained, whether the target terminal equipment is in the coverage area of the adjacent high-altitude base station or not can be detected, if the target terminal equipment is in the coverage area of the adjacent high-altitude base station, the terminal can detect the signal intensity of the adjacent base station, if the detected signal intensity of the adjacent base station is greater than an intensity threshold value, the target terminal equipment is considered to be in the coverage area of the adjacent high-altitude base station and can be accessed to the adjacent high-altitude base station, and then the target terminal equipment is controlled to be accessed to the adjacent high-altitude base station; or the terminal reports the detection measurement information to the station.
In summary, the present embodiment provides a processing method for preventing a terminal from losing coverage by a high-altitude base station, where the method includes acquiring attitude data of the high-altitude base station and environment information of an environment where the high-altitude base station is located; predicting target terminal equipment which is to lose coverage after preset time based on the attitude data and the environment information; and controlling the target terminal equipment to establish a D2D link with the high-altitude base station so that the target terminal equipment interacts with the high-altitude base station through a D2D link. According to the method and the device, the target terminal equipment which is covered is lost after the preset time is predicted by obtaining the attitude data and the environmental information of the high-altitude base station, and the target terminal equipment is immediately controlled to establish a D2D link with the high-altitude base station after the target terminal equipment is predicted, so that the situation that the call is dropped due to no signal coverage of the terminal caused by the movement of the high-altitude base station can be prevented, and the stability of terminal service can be guaranteed.
