Technical Field
[0001] The present invention relates to the field of communications, and in particular to a beam adjustment method, device, electronic equipment and computer program product for unmanned aerial vehicles. Background Art
[0002] Currently, 5G networks mainly cover the ground. The cost of building new airspace dedicated networks is high, while directly using existing networks will have problems such as poor signals.
[0003] For signal coverage scenarios, the absolute value of the signal level is not the bottleneck. The core is to form dominant coverage and provide high SINR. Therefore, it is necessary to systematically study low-altitude network optimization methods to improve signal quality.
[0004] When using existing website addresses, how to ensure the quality of 5G networks at an altitude of 300 meters and on the large network at the same time is the biggest difficulty in airspace networking.
[0005] Figure 1 It is a schematic diagram of RSRP of a low-altitude network according to the prior art. Figure 2 This is a schematic diagram of a low-altitude network SINR situation according to the prior art. Figure 3 This is a schematic diagram of drone airspace coverage based on existing technology. After testing and analysis, the airspace will receive signals from more than 10 neighboring cells, mainly affected by the reflection of large ground network signals, resulting in an average downlink SINR of around 0dB. The number of switching and disconnection times will be 2-5 times higher than that on the ground, seriously affecting the perception of airspace users.
[0006] The existing low-altitude network deployment solutions mainly include: heterodyne frequency private network deployment and public network air beam co-extension deployment.
[0007] Figure 4 is a schematic diagram of a heterodyne frequency private network deployment according to the prior art, such as Figure 4 As shown in the figure, the deployment method is to build new frequency-differential air-to-air equipment to cover low altitude. The advantages of this method are: dedicated frequency and good user perception; the disadvantages of this method are: high deployment cost and tight frequency resources in some hot spots.
[0008] Figure 5 This is a schematic diagram of a public network air beam coexistence deployment according to the prior art, such as Figure 5 As shown in the figure, the deployment method is to reuse the old public network base station and add an air beam. The advantages of this method are: low deployment cost; the disadvantages of this method are: large co-frequency interference between air and ground, air beams interfere with the ground, and ground beams interfere with low altitude.

[0044] In order to enable those skilled in the art to better understand the scheme of the present invention, the technical scheme in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.
[0045] It should be noted that the terms "first", "second", etc. in the specification and claims of the present invention and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchanged where appropriate, so that the embodiments of the present invention described herein can be implemented in an order other than those illustrated or described herein. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions, for example, a process, method, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units that are clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.
[0046] First, some nouns or terms that appear in the description of the embodiments of the present application are subject to the following explanations:
[0047] DOA (direction-of-arrival): The angle of the UE relative to the normal of the antenna panel measured using the channel information of the SRS. MR.VAOA defines the estimated angle of a user in the vertical direction relative to the reference direction (antenna mechanical downtilt angle).
[0048] According to an embodiment of the present invention, an embodiment of a beam adjustment method for a UAV is provided. It should be noted that the steps shown in the flowchart of the accompanying drawings can be executed in a computer system such as a set of computer executable instructions, and although a logical order is shown in the flowchart, in some cases, the steps shown or described may be executed in an order different from that shown here.
[0049] Figure 6 is a flow chart of a beam adjustment method for a UAV according to an embodiment of the present invention. Figure 6 As shown, the method comprises the following steps:
[0050] Step S602, detecting an object to be identified that is connected to the target base station, wherein the object to be identified includes at least: a drone;
[0051] Step S604: when the object to be identified is a drone, generate configuration information, wherein the configuration information includes at least: first configuration information and second configuration information, the first configuration information is used to instruct the target base station to transmit a first number of beams into the air and transmit a second number of beams to the ground, and the second configuration information is used to instruct the neighboring base station to stop transmitting the first number of beams and transmit the second number of beams to the ground, and the neighboring base station has a neighboring relationship with the target base station;
[0052] Step S606: Send second configuration information to the neighboring base station;
[0053] Step S608: adjust the beam transmitted by the target base station according to the first configuration information.
[0054] In an embodiment of the present invention, when a drone accesses a target base station, the beams emitted by the target base station can be adjusted so that the target base station emits beams into the air according to a first number, and emits beams to the ground according to a second number, and at the same time, second configuration information is sent to a neighboring base station of the target base station. The second configuration information instructs the neighboring base station to adjust the beams emitted by the neighboring base station, so that the neighboring base station stops emitting the first number of beams and emits the second number of beams to the ground. This can not only provide the beams required for communication in the air, but also avoid interference of excessive beams emitted to the ground with the beams emitted into the air, thereby achieving the technical effect of improving the signal quality of the low-altitude network, and thus solving the technical problem of poor signal quality of the low-altitude network.
[0055] In the above step S602, the target base station may be a 5G base station GNB.
[0056] In the above step S602, the object to be identified may be a terminal device that uses a 5G network to access a target base station, and the terminal device includes: drones, mobile phones, IoT devices and other smart terminals.
[0057] In the above step S604, the beam refers to a beam of wireless signals pointing in a specific direction. By adjusting the shape of the electromagnetic beam transmitted by the antenna, effective communication coverage can be achieved.
[0058] Optionally, the 5G base station GNB may include multiple beams, and the multiple beams may horizontally cover a sector-shaped area with the 5G base station GNB as the center of the sector.
[0059] In the above step S604, the beam sent to the air is used as the air beam, and the beam sent to the ground is used as the ground beam. The transmission condition of the ground beam is the same as the default beam transmission direction of the base station. Among them, the first configuration information and the second configuration information can select the air beam from the multiple beams of the base station, and then the first configuration information instructs the target base station to transmit the air beam, and the second configuration information instructs the neighboring base station to stop transmitting the air beam.
[0060] That is, the similarities between the first configuration information and the second configuration information are: selecting an air beam from multiple beams of the base station; the difference between the first configuration information and the second configuration information is: the first configuration information indicates to transmit the selected air beam, and the second configuration information indicates to stop transmitting the selected air beam, that is, the first configuration information indicates that the air beam is in a transmitting state, and the second configuration information indicates that the air beam is in a closed state.
[0061] Optionally, the number of beams in the base station may be 7, the first number may be 3, and the second number may be 4.
[0062] Optionally, the target base station may be determined by a neighboring cell list, where the neighboring cell list is used to record a set of multiple neighboring cell base stations adjacent to the target base station.
[0063] In the above step S604, the neighboring base station refers to other base stations in the mobile communication network that are adjacent to the target base station and may cause signal interference or require handover.
[0064] In the above step S604 and step S606, the target base station may include multiple neighboring base stations, and the target base station may send the second configuration information to each neighboring base station.
[0065] In the above step S608, a first number of air beams are selected from the multiple beams transmitted by the target base station, and the transmission angles of the air beams are adjusted so that the air beams are transmitted into the air.
[0066] As an optional embodiment, detecting the object to be identified that accesses the target base station includes: obtaining registration request information sent by the object to be identified to the target base station, wherein the registration request information carries at least the slice identifier to be identified of the object to be identified; detecting whether the slice identifier to be identified of the object to be identified is the target slice identifier; when the slice identifier to be identified is the target slice identifier, determining that the object to be identified is a drone.
[0067] In the above embodiment of the present application, the object to be identified may be a terminal that uses a 5G network to access a target base station. When the terminal accesses the target base station, the terminal sends a registration request message to the target base station. The drone may carry a target slice identifier unique to the drone in the registration request message. When the target base station receives the registration request message, it may identify whether the registration request message carries the target slice identifier, thereby identifying the drone.
[0068] Optionally, the registration request information may be that when the connected drone comes online, a RegistrationRequest (UE sends to (R)AN)-NA message is sent to the 5G base station, and the message includes parameters, registration request (registration type, SUCI or 5G-Guti or PEI, last visited TAI (if available), security parameters, requested NSSAI (such as target slice identifier).
[0069] As an optional embodiment, when the object to be identified is a drone, generating configuration information includes: when the object to be identified is a drone, obtaining a measurement report reported by the drone to the target base station, wherein the measurement report carries at least an angle field, and the angle field is used to indicate the relative angle between the drone and the target base station; when the relative angle meets a preset angle threshold, generating configuration information; when the relative angle does not meet the preset angle threshold, determining not to adjust the beam transmitted by the target base station.
[0070] In the above embodiment of the present application, after the drone accesses the target base station, the target base station can receive the measurement report reported by the drone. The target base station can determine the relative angle between the drone and the target base station through the angle field carried in the measurement report, and further determine whether the drone has left the ground. Then, when the relative angle meets the preset angle threshold, that is, when the drone leaves the ground, configuration information is generated to instruct the target base station and the neighboring base station to adjust the beam according to the configuration information; however, when the relative angle does not meet the preset angle threshold, that is, when the drone leaves the ground, the drone is equivalent to an intelligent terminal (such as a mobile phone) used on the ground, and therefore there is no need to adjust the beam emitted by the target base station.
[0071] It should be noted that for some terminals used in high-rise buildings (such as smart phones), the relative angle between the terminal and the target base station may also meet the preset angle threshold. However, after the above step S602, it has been determined that the terminal does not belong to a drone. Therefore, beam adjustment will not be performed for the terminals used in high-rise buildings.
[0072] Optionally, the measurement report may be an MR message reported by a UAV, and the angle field carried in the measurement report may be a VAOA field in the MR message, wherein VAOA defines an estimated angle of a user in a vertical direction relative to a reference direction (antenna mechanical downtilt angle), such as DOA.
[0073] Optionally, DOA (direction-of-arrival) is an angle of the UE relative to the normal of the antenna panel measured using the channel information of the SRS.
[0074] As an optional embodiment, adjusting the beam transmitted by the target base station according to the first configuration information includes: among the multiple beams transmitted by the target base station, selecting a first number of beams at intervals as air beams according to the horizontal range covered by the beams; and adjusting the inclination angle of the air beam so that the air beam is transmitted into the air.
[0075] In the above-mentioned embodiments of the present application, the multiple beams transmitted by the target base station can cover a fan-shaped area in the horizontal plane direction. Among the multiple beams covering the fan-shaped area, a first number of beams can be selected at intervals as air beams, and then the technical effect of transmitting air beams into the air can be achieved by adjusting the inclination angle of the antenna sending the air beam.
[0076] Optionally, the air beam can be selected at intervals from multiple beams of the base station. For example, there may be 7 beams in the base station, and the 7 beams cover a sector-shaped area, and the 7 beams are arranged in a clockwise order, namely: the first beam, the second beam, the third beam, the fourth beam, the fifth beam, the sixth beam, and the seventh beam; wherein the first number of air beams may be 3, and the second number of ground beams may be 4, then the air beams selected at intervals may be: the second beam, the fourth beam, and the sixth beam; and further, the ground beams may be: the first beam, the third beam, the fifth beam, and the seventh beam.
[0077] Optionally, the second number of beams are ground-facing beams, and the tilt angle of the antenna transmitting the ground-facing beams does not need to be adjusted.
[0078] As an optional embodiment, sending the second configuration information to the neighboring base station includes: the target base station sending the second configuration information to the neighboring base station through an interface between wireless nodes.
[0079] In the above embodiments of the present application, the interface between wireless nodes may be the X2 / Xn interface of the target base station, wherein X2 is the interface between eNBs and en-gNB between wireless nodes in a non-independent network; Xn is the interface between ng-eNB and eNB / gNB between wireless nodes in an independent network; the target base station and the neighboring base station transmit the second configuration information based on the interface between wireless nodes, so that the neighboring base station can obtain the second configuration information as soon as possible and adjust the beam according to the second configuration information as soon as possible.
[0080] As an optional embodiment, the method also includes: detecting whether the UAV needs to switch from the target base station to the neighboring base station; when the UAV needs to switch from the target base station to the neighboring base station, the target base station sends a reconfiguration message to the UAV, wherein the reconfiguration message carries at least the neighboring base station's neighboring configuration information, and the UAV directly accesses the neighboring base station based on the neighboring configuration information.
[0081] In the above-mentioned embodiment of the present application, when the drone needs to switch from the target base station to the neighboring base station, the target base station can send a reconfiguration message carrying the neighboring cell configuration information of the neighboring base station to the drone. After receiving the reconfiguration message, the drone can use the neighboring cell configuration information carried in the reconfiguration message to directly access the neighboring base station without sending registration request information to the neighboring base station again, thereby improving the switching speed of the drone from the target base station to the neighboring base station and avoiding the drone from being disconnected during the process of switching from the target base station to the neighboring base station.
[0082] As an optional embodiment, the method also includes: when the drone needs to switch from the target base station to the neighboring base station, the target base station sends third configuration information to the neighboring base station, and adjusts the beam transmitted by the target base station according to the second configuration information, wherein the third configuration information is at least used to instruct the neighboring base station to adjust the transmitted beam according to the first configuration information, and send the second configuration information to the surrounding base stations, and there is a neighboring relationship between the surrounding base stations and the neighboring base stations.
[0083] In the above embodiment of the present application, when the drone needs to switch from the target base station to the neighboring base station, the target base station sends the third configuration information to the neighboring base station, and adjusts the beam transmitted by the target base station according to the second configuration information, so that the neighboring base station can switch to the target base station based on the third configuration information, and redetermine the neighboring base station, and then send the second configuration information to the redetermined neighboring base station, and can also switch the target base station to the neighboring base station, thereby ensuring that the neighboring base station has completed the air beam relay before the networked drone switches from the target base station to the neighboring base station.
[0084] The present invention also provides a preferred embodiment, which provides a low-cost optimization method for low-altitude drone networks using the ground public network. Low-altitude flying drones are identified on the network side. In view of the characteristics of cluttered low-altitude network signals and no dominant coverage signals, the service cell opens the air beam in real time, and the surrounding public network cells reduce the transmission beam (reduce the bias toward high-level coverage beams).
[0085] Figure 7 is a schematic diagram of a low-cost optimization process of a UAV low-altitude network using a ground public network according to an embodiment of the present invention. Figure 7 As shown, the following steps are included:
[0086] Step S72, UAV low-altitude flight detection.
[0087] Specifically, through the exclusive slice user registration of the networked drone, the joint user reports the changes of the VDOA field in the MR to identify low-altitude users.
[0088] Step S74, low-altitude drone user notification.
[0089] Specifically, all private network base stations with neighboring cell relationships are notified through the Xn interface that drone users are flying at low altitudes.
[0090] Step S76, the UAV performs low-altitude joint beam optimization.
[0091] Specifically, the service cell is automatically adjusted to a 3-up 4-down scheme, and the surrounding base stations are adjusted to a 4-down scheme to reduce air interference, while non-peripheral base stations maintain the default 7-down beam scheme.
[0092] Step S78, UAV mobile beam relay solution.
[0093] Specifically, IoT drones perform cross-cell switching during movement, and a beam relay solution is designed to ensure business connectivity.
[0094] Figure 8 is a schematic diagram of a new dedicated slicing process for a networked drone according to an embodiment of the present invention, such as Figure 8 As shown, when the connected drone goes online, it needs to send a Registration Request (UE sends to (R)AN)-NA message to the 5G base station. The message contains parameters, registration request (registration type, SUCI or 5G-Guti or PEI, last visited TAI (if available), security parameters, and requested NSSAI. The NSSAI can be a dedicated slice that can be added for the connected drone, that is, the target slice identifier.
[0095] Fig. 9 is a schematic diagram of adding a dedicated slice for a networked drone service according to an embodiment of the present invention, such as Fig. 9 As shown, the drone slice (XXXXX, i.e., the target slice identifier) is added to the NSSAI part (such as the S-NSSAI and NG_CP binding part, and the S-NSSAI and NG_UP binding part) carried by the registration request.
[0096] As an optional embodiment, when the networked drone goes online, it does not necessarily fly at low altitude. The present application determines whether the drone is flying at low altitude through the VAOA field (i.e., the angle field) in the MR message reported by the 5G network drone.
[0097] It should be noted that MR.VAOA (that is, the VAOA field in the MR message) defines an estimated angle of a user in the vertical direction relative to the reference direction (antenna mechanical downtilt angle) (that is, the vertical angle of arrival of the gNB antenna).
[0098] Optionally, the relative angle between the drone and the target base station can be the vertical arrival angle of the gNB antenna.
[0099] It should be noted that the vertical arrival angle of the gNB antenna defines the estimated angle of a user (such as a drone) in the vertical direction relative to the reference direction (such as the mechanical downtilt angle of the base station antenna). The reference direction specified here is the direction specified in 3GPP 38.2155.2.4 GCS.
[0100] Fig.10 is a schematic diagram of a direction specified by a GCS according to an embodiment of the present invention Figure 1 , Fig.11 is a schematic diagram of a direction specified by a GCS according to an embodiment of the present invention Figure 2 , Fig.12 is a schematic diagram of a direction specified by a GCS according to an embodiment of the present invention Figure 3 ,like Fig.10 , Fig.11 and Fig.12 As shown, the antenna vertical arrival angle is the downward angle relative to the reference direction with an accuracy of 2 degrees.
[0101] Fig.13 is a schematic diagram of a vertical arrival angle of a gNB antenna for a networked drone according to an embodiment of the present invention, such as Fig.13 As shown, assuming that the antenna downtilt angle is θ, when 90-θ<5G VAOA<270-θ, it can be determined that the terminal (ie, the drone) is located at a low altitude.
[0102] It should be noted that since this application uses the dedicated slice of the network drone (that is, the target slice identifier) for identification, even if the VAOA of some high-rise building users can meet this requirement, if the slice identifier is incorrect, it will not be identified as a drone flying at low altitude.
[0103] Fig.14 is a schematic diagram of a low-altitude arrival notification of a drone according to an embodiment of the present invention. Fig.14 As shown, when there is a drone flying at low altitude over the target base station, the target base station notifies the surrounding base station service base station (i.e., the neighboring base station) with a neighboring cell relationship between the adjacent base stations through the Xn / X2 interface that there is a drone flying at low altitude. Since the current Xn / X2 private message transmission delay is within 5 TTIs (5ms), normal and timely notification of the surrounding cells can be guaranteed.

In this application, the service cell (that is, the target base station) is automatically adjusted to a 3-up 4-down scheme, and the surrounding base stations (that is, neighboring base stations) are adjusted to a 4-down scheme to reduce air interference.

[0108] Fig.19 is a schematic diagram of a beam relay solution when a networked drone moves according to an embodiment of the present invention. Fig.19 As shown, when the IoT drone is moving, it needs to switch across cells. During the process, abnormal events such as disconnection and untimely switching are prone to occur. This application designs a beam relay solution for cell switching, which specifically includes the following steps:
[0109] Step S1901: After access is completed, the target base station GNB sends an RRC reconfiguration message including A3 measurement control information.
[0110] Step S1902, the drone UE sends a measurement report to the target base station GNB, including the severcellId, PCI, SSBID, SSB RSRP / RSRQ of the serving cell and the PCI, SSB RSRP, etc. of the neighboring cell. That is, in the stage where the drone accesses the target base station, the drone sends a measurement report to the target base station, in addition to the measurement report for the target base station, a measurement report for the neighboring base station is also included in the measurement report, and the target base station and the neighboring base station can be configured based on the measurement report, so that after the drone accesses the target base station, it can be ensured that the drone can switch to the neighboring base station at any time.
[0111] Step S1903: base station interaction decision: Through base station interaction decision, it is determined whether the drone needs to switch from the target base station to the neighboring base station.
[0112] In step S1904, the target base station GNB sends an RRC reconfiguration message to the drone UE, wherein the RRC reconfiguration message carries the switching target frequency, PCI, and the C-RNTI and dedicated Preamble configured for the UE; that is, the reconfiguration message carries at least the neighboring cell configuration information of the neighboring base station.
[0113] Step S1905: The drone UE initiates random access to the communication cell corresponding to the neighboring base station.
[0114] It should be noted that, after the above step S1904 is performed, the target base station sends a handover command, and the handover command instructs the target base station to execute the following steps:
[0115] In step S19042, the source base station (i.e., the target base station) transmits the current beam scheme of the source base station (i.e., the target base station) (such as the first configuration information, i.e., three up and four down) to the neighboring base station through message interaction via the Xn interface. After receiving the beam scheme, the neighboring base station immediately executes the beam scheme. At the same time, the neighboring base station sends the surrounding base station beam scheme (such as the second configuration information) to the surrounding base stations as required.
[0116] In step S19044, the source base station (ie, the target base station) immediately switches to the base station beam scheme (such as the second configuration information) around the drone service base station to reduce air interference.
[0117] In the above-mentioned embodiment of the present application, through step S19042 and step S19044, it can be ensured that the target base station has completed the air beam relay before the networked drone switches to the target base station.
[0118] The above-mentioned embodiment of the present application marks the networked drone through dedicated slices, and obtains the estimated angle of the drone in the vertical direction of the mechanical downtilt angle of the antenna through 5G VDOA, so as to identify whether the drone is flying at low altitude, and realize accurate identification of low-altitude 5G networked drone terminals; for low-altitude drone flight, the beam optimization scheme is adjusted in real time, and a beam relay scheme is designed during the drone inter-station switching process to ensure switching continuity, and through specific differentiated beams and differentiated mobility management strategies, a scenario-based tidal optimization scheme for low-altitude drones to reside in the network is implemented to enhance low-altitude user perception.
