Description

Technical Field

[0001] The present application relates to the field of communication technology, and in particular to an airspace information acquisition method, an airspace information sending method, a communication perception terminal, an airspace information sending device, a storage medium, and a computer program product device. Background Art

[0002] Perceptual communication refers to a technology that combines communication technology with perception technology. Communication mainly refers to the transmission and reception of information, and perception mainly refers to obtaining information about the environment or objects through various sensors. By combining communication and perception technologies, it is possible to better adapt to and utilize environmental information and improve the intelligence and efficiency of the system. In the low-altitude perception communication fusion scenario, it is necessary to use base stations to perceive communication perception terminals (such as drones) and provide perception services. At the same time, the base stations themselves need to provide cellular coverage and communication services for communication perception terminals. According to the communication perception coverage capability of the base station, a two-dimensional or three-dimensional flight airspace can be delineated. In this flight airspace, the perception and communication services provided by the base station can provide safe flight guarantees for the communication perception terminal. At present, due to the problem of limited perception and coverage of base stations, the safe flight space of communication perception terminals under the perception and communication services of base stations is limited.

[0044] It should also be understood that the description of the various embodiments in the present disclosure focuses on the differences between the various embodiments, and the same or similar aspects thereof can be referenced to each other, and for the sake of brevity, they will not be described one by one.

[0045] At the same time, it should be understood that for the convenience of description, the sizes of the various parts shown in the drawings are not drawn according to the actual proportional relationship.

[0046] The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the present disclosure, its application, or uses.

[0047] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered as part of the specification.

[0048] It should be noted that like reference numerals and letters refer to similar items in the following figures, and therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.

[0049] In addition, in order to avoid obscuring the present disclosure due to unnecessary details, only the processing steps and / or device structures closely related to at least the scheme according to the present disclosure are shown in the drawings, and other details that are not closely related to the present disclosure are omitted. It should also be noted that similar reference numerals and letters in the drawings indicate similar items, and therefore once an item is defined in one drawing, it does not need to be discussed again for subsequent drawings.

[0050] In the related technologies known to the inventor, there are blind spots in the perception and / or communication of the base station to the communication perception terminal:

[0051] 1. When the base station uses P waves for communication perception, due to the physical limitations of the P wave's transmission time slot and protection time slot, there is a perception "dead zone" with a radius of tens to hundreds of meters in the perception range; when the base station uses a mixture of C waves and P waves for communication perception, although the perception "dead zone" problem can be solved to a certain extent, the base station needs to be equipped with an additional set of C wave transceiver devices, which will increase costs and power consumption; among them, P waves are pulse waves (Pulse Wave), which are usually used in millimeter wave outdoor base stations to achieve high-speed wireless connections; C waves (continuous waveform) are continuous waves.

[0052] 2. Base station antennas are usually configured with a mechanical downtilt angle. Although the digital beamforming technology can adjust the beam direction to a certain extent and make the beam rise, in cellular deployment and site planning, considering the influence of factors such as interference between control stations, the amplitude of the beam rise and the transmission power will be limited, resulting in difficulties for the base station to provide perception and coverage for objects and areas that are higher than the base station antenna beam.

[0053] Due to the superposition of the above two situations, the problems of base station perception and coverage limitation are more prominent, which limits the safe flight space of communication perception terminals under base station perception and communication services.

[0054] Figure 1 FIG. 1 is a flow chart of some embodiments of the airspace information acquisition method according to the present disclosure. Figure 1 As shown, the airspace information acquisition method is applied to a communication perception terminal, including step S101.

[0055] Step S101, based on the received airspace indication message, obtain the flight airspace information corresponding to the base station and the valid time information corresponding to the flight airspace information; or, obtain the pre-configured flight airspace information and valid time information.

[0056] The communication sensing terminal includes a drone, etc., the base station may be a telepathic integrated base station, etc., the flight airspace information corresponding to the base station includes airspace range information and other information, and the airspace range information includes range information of a direct sensing area and / or an indirect sensing area associated with the location of the communication sensing terminal. The valid time information corresponding to the flight airspace information may be information such as a valid time range, within which the corresponding flight airspace information is valid, and outside which the corresponding flight airspace information is invalid.

[0057] The direct perception area and the indirect perception area can be three-dimensional space areas, and the range information of the direct perception area and the indirect perception area includes at least one of the following information: three-dimensional coordinate set information, three-dimensional space information indicated based on the three-dimensional coordinate set, three-dimensional space set information based on the three-dimensional coordinate set indication, etc.

[0058] The airspace information sending device can determine and send an airspace indication message to the communication perception terminal. The airspace indication message can be a variety of messages, and the airspace indication message carries flight airspace information and effective time information. The flight airspace information and effective time information can also be pre-configured in the communication perception terminal.

[0059] The airspace information sending device can be a variety of devices, such as communication-aware application-side devices, base stations, and network-side devices of the communication network; the application-side device can be a control device, a scheduling device, etc. of the communication-aware terminal; the network-side device can be an application server deployed on the network side for providing communication, perception, control, and other capabilities of the communication-aware terminal. The application-side device, the network-side device, etc. can send the flight airspace information and effective time information corresponding to the communication-aware terminal and multiple base stations to the communication-aware terminal; the base station can send the flight airspace information and effective time information corresponding to the communication-aware terminal and itself to the communication-aware terminal.

[0060] The airspace information sending device can determine the flight airspace information corresponding to the base station and the corresponding effective time information according to the location or route information of the communication perception terminal during the network planning stage or when the flight route is planned or updated. For example, the airspace information sending device determines the base station and other communication perception terminals that provide perception and coverage at this location or route according to the location and / or route information of the communication perception terminal, and then determines the direct perception area and indirect perception area, as well as the base station and other communication perception terminals according to the planning / deployment information of these base stations and the location or route information of other communication perception terminals, and determines the corresponding effective time information.

[0061] The airspace information acquisition method disclosed in the present invention proposes a method for indicating airspace range information to a communication perception terminal. The communication perception terminal can expand the perception range of the communication perception terminal by acquiring the flight airspace information corresponding to the base station and the effective time information corresponding to the flight airspace information. Under the premise of ensuring the perception of the communication perception terminal, the available flight space range of the communication perception terminal can be expanded, thereby improving flight efficiency and safety.

[0062] In some embodiments, the flight airspace information includes perception service configuration information, which is used to provide perception services for the communication perception terminal; the perception service configuration information may also be perception service indication information. The perception service configuration information includes information of a first communication base station associated with the communication perception terminal and / or information of a first other communication perception terminal in a direct perception area, etc.

[0063] The information of the first communication base station may be information such as the base station number, and the first communication base station provides direct perception services for the communication perception terminal; the first other communication perception terminal may be other drones or other equipment located in the direct perception area, and the information of the first other communication perception terminal may be identification information of the first other communication perception terminal, etc. The information of the first other communication perception terminal is used to provide direct or indirect perception services for the communication perception terminal.

[0064] The flight airspace information includes communication service provision information, which is used to provide communication services for the communication perception terminal. The communication service provision information includes the second communication base station information associated with the communication perception terminal and / or the second other communication perception terminal information in the direct perception area.

[0065] The second communication base station information may be information such as the base station number, and the second communication base station provides direct communication services for the communication perception terminal; the second other communication perception terminal may be other drones and other equipment located in the direct perception area, and the second other communication perception terminal information may be identification information of the second other communication perception terminal, etc. The second other communication perception terminal information is used to provide direct or indirect communication services for the communication perception terminal.

[0066] When the communication perception terminal is located in the indirect perception area, the communication perception terminal can transmit data with the second communication base station through a second other communication perception terminal; the communication perception terminal can communicate with one or more base stations by communicating with the second communication base station; or, the communication perception terminal directly transmits data with one or more second communication base stations.

[0067] The flight airspace information may also include range information of a non-perception area associated with a communication perception terminal. The range of the non-perception area is outside the direct perception area and the indirect perception area. A specific spatial area may be set as a non-perception area. There is no intersection between the non-perception area and the direct perception area and the indirect perception area, and its function is similar to that of a no-fly zone.

[0068] Figure 2 FIG. 1 is a flow chart of the flight airspace update process in some embodiments of the airspace information acquisition method disclosed in the present invention. Figure 2 As shown, the flight airspace update processing method is applied to the communication perception terminal, including step S201 and step S202.

[0069] Step S201, determining whether the airspace range information is valid based on the valid time information.

[0070] Step S202: When it is determined that the airspace range information is valid, flight airspace update processing is performed based on the airspace range information and perception service configuration information.

[0071] For example, the valid time information is the valid time interval [time A, time B]; when the communication perception terminal performs flight airspace update processing actively or based on the received control instructions, it determines whether the time for performing the flight airspace update processing is within the valid time interval [time A, time B]. If so, it determines that the airspace range information is valid, based on the airspace range information and the perception service configuration information.

[0072] A variety of methods can be used to perform flight airspace update processing. In the case where the perception service configuration information only includes the first other communication perception terminal information, it moves to or remains in the indirect perception area according to the airspace range information; in the case where the perception service configuration information only includes the first communication base station information, it moves to or remains in the direct perception area according to the airspace range information.

[0073] For example, if the communication perception terminal device determines, based on the airspace range information and the perception service configuration information, that the direct communication base station information (first communication base station information) associated with it is empty, but the information of other communication perception terminal devices in the direct perception area (first other communication perception terminal information) is not empty, then it is determined that the location of the communication perception terminal cannot use direct perception and needs to be moved to the indirect perception area.

[0074] If the communication perception terminal device determines, based on the airspace range information and the perception service configuration information, that the information of other communication perception terminal devices (first other communication perception terminal information) in the direct perception area associated with it is empty, but the direct communication base station information (first communication base station information) is not empty, then the location of the communication perception terminal device cannot use indirect perception, and the communication perception terminal device will move to the direct perception area.

[0075] In the case where the perception service configuration information includes the first other communication perception terminal information and the first communication base station information, the communication perception terminal may move to the indirect perception area or the direct perception area.

[0076] In some embodiments, the direct sensing area includes a first area, a second area, or a third area; the indirect sensing area includes a fourth area associated with the first area, a fifth area associated with the second area, or a sixth area associated with the third area. The direct sensing area and the indirect sensing area are areas in a three-dimensional space and can be associated with base station signal coverage capabilities, etc.

[0077] The direct perception area can be subjected to a variety of fusion processing, for example, the first area and the second area can be fused into one area, and the third area can be a separate area; the first area can be a separate area, and the second area and the third area can be fused into one area. The indirect perception area can be subjected to a variety of fusion processing, for example, the fourth area and the fifth area can be fused into one area, and the sixth area can be a separate area; the fourth area can be a separate area, and the fifth area and the sixth area can be fused into one area.

[0078] The distance between the location within the first area and the base station is greater than the first distance threshold and less than the second distance threshold; the distance between the location within the fourth area and the base station is greater than the third distance threshold and less than or equal to the first distance threshold, or the distance between the location within the fourth area and the base station is greater than or equal to the second distance threshold and less than the fourth distance threshold.

[0079] In such Figure 3A In the application scenario shown, the direct sensing area (first area) is located at a distance d∈D from the base station. direct :d 1 <D direct <d 2 space, where the first distance threshold is d 1 , the second distance threshold is d 2 The indirect sensing area (the fourth area) includes the indirect sensing area a and the sensing area b. The indirect sensing area a is located at a distance d∈D from the base station. indirect1 :d 0 <D indirect1 ≤d 1; Among them, the third distance threshold is d 0 , the indirect sensing area b is located at a distance d∈D from the base station indirect2 :d 2 ≤D indirect2 <d 3 space; where the fourth distance threshold is d 3 .

[0080] like Figure 3A As shown, the location of the base station can be set as the origin 0, and multiple distance thresholds d can be set. 0 -d 3 , which is used to divide the direct perception area, indirect perception area and non-perception area. The non-perception area a includes a part of the base station communication signal blind area, the P-wave perception signal blind area or the dead zone range; the indirect perception area a is located within the base station communication signal coverage range and in the P-wave perception signal blind area, and the indirect perception area a (the distance between it and the base station is d 0 -d 1 The area of ​​the interval) is within the range reachable by D2D communication (direct communication between sensing terminals).

[0081] The direct sensing area is located within the coverage of the base station communication signal; the indirect sensing area b is located outside the coverage of the base station communication signal, and the indirect sensing area b (the distance between it and the base station is d 2 -d 3 The area of ​​the interval is located within the range of the D2D communication (direct communication between perception terminals). The non-perception area a is located outside the coverage of the base station communication signal, and the non-perception area b is located outside the range of the D2D communication (direct communication between perception terminals).

[0082] Figure 3A-3C The base station can provide direct communication services to the communication perception terminals in the direct perception area, and can provide indirect communication services to the communication perception terminals in the indirect perception area. However, it cannot guarantee to provide direct communication services to the communication perception terminals in the indirect perception area.

[0083] The height of the position within the second area is greater than the first height threshold and less than the second height threshold, and the height of the position within the fifth area is greater than the second height threshold and less than the third height threshold. Figure 3B In the application scenario shown, the direct sensing area (second area) and the indirect sensing area (fifth area) are located at different heights. Multiple height thresholds H can be set. 0 -H 2 , which is used to divide the direct perception area, indirect perception area and non-perception area. The direct perception area (second area) is located at height H∈H Direct :H 0<H Direct <H 1 The space, where the first height threshold is H 0 , the second height threshold is H 1 ; The indirect perception area (fifth area) is located at height H∈H inDirect :H 1 <H inDirect <H 2 The third height threshold is H 2 , H 0 The value can be 0 or not.

[0084] The indirect sensing area is located within the range accessible by D2D communication (direct communication between sensing terminals); the height of the position in the non-sensing area is greater than or equal to H 2 , the non-sensing area is outside the range accessible by D2D communication (direct communication between sensing terminals). 1 The area is the area that can be covered by the scanning angle of the base station communication beam / P wave, and the height is greater than or equal to H 1 The area is the area that cannot be covered by the scanning angle of the base station communication beam / P wave.

[0085] Direct perception areas, indirect perception areas, non-perception areas, etc. are set by distance or height; for example, different distance or height thresholds can be set according to one or more factors such as spectrum, base station site planning, antenna angle, signal coverage range, and relevant regulations, or different distance or height thresholds can be set according to distance (or longitude and latitude) and height (or altitude); different distance or height thresholds can be used to set direct perception areas, indirect perception areas, non-perception areas, etc.

[0086] The third area is the intersection area of ​​the base station communication signal coverage area and the coverage area of ​​the P wave sent by the base station, and the sixth area is the set area outside the base station communication signal coverage area and / or the set area outside the coverage area of ​​the P wave sent by the base station.

[0087] In such Figure 3C In the application scenario shown, the direct sensing area and the indirect sensing area can be determined based on the beam coverage / sensing range and the P wave coverage range. Multiple distance thresholds d can be set 0 -d 3 , which is used to divide the direct perception area, indirect perception area and non-perception area; multiple height thresholds H can also be set 0 -H 2 , which is used to divide the direct perception area, indirect perception area and non-perception area.

[0088] The direct sensing area (third area) is the intersection or union of the base station beam or sensing signal coverage area and the P wave coverage area sent by the base station; the base station communication signal can be a base station beam or sensing signal, etc., the base station coverage can be the coverage range of the communication service provided by the base station, and the base station beam refers to the control beam and data channel beam of the base station providing communication services. For example, Figure 3C The direct perception area (third area) in can be set as follows Figure 3A and Figure 3B The intersection of the direct perception areas in .

[0089] The indirect sensing area (sixth area) is an area within a preset spatial distance outside the direct coverage area (a set area outside the base station communication signal coverage area and / or a set area outside the P wave coverage area sent by the base station); wherein the preset spatial distance can be set according to the application scenario. For example, Figure 3C The indirect perception area (third area) in Figure 3A and Figure 3B Indirectly aware locale in .

[0090] The airspace information acquisition method in the above-mentioned embodiment is that the communication perception terminal obtains the flight airspace information corresponding to the base station and the valid time information corresponding to the flight airspace information. When it is determined that the airspace range information is valid, the flight airspace update processing is performed based on the airspace range information and the perception service configuration information. Under the premise of ensuring the perception of the communication perception terminal, the available flight space range of the communication perception terminal can be expanded, thereby improving flight efficiency and safety.

[0091] Figure 4 FIG. 1 is a flow chart of some embodiments of the method for sending airspace information according to the present disclosure. Figure 4 As shown, the airspace information sending method is applied to the airspace information sending device, including step S401.

[0092] Step 401, sending an airspace indication message to the communication awareness terminal, so that the communication awareness terminal obtains the flight airspace information corresponding to the base station and the valid time information corresponding to the flight airspace information based on the airspace indication message.
