Description

Technical Field

[0002] With the widespread expansion of 5G industry applications, the application of "5G + drones" has also penetrated into various aspects of social governance, economic development, and public welfare services. Drones have attracted widespread attention across various industries due to their high maneuverability, flexibility, ease of maintenance, and controllability. They have particularly important potential applications in wireless systems. For low-altitude communications, the drone industry can leverage existing 5G network infrastructure and a mature industrial chain to achieve rapid deployment in low-altitude service areas.

[0003] During the flight of a drone, if it flies into the blind spot of the main lobe beam of the low-altitude cell above this station, the signal is poor. At this time, the interference signal received from the remote low-altitude base station is strong, and switching may occur, or even reconstruction to the ground carrier; when it flies into the coverage area of the main lobe beam of the low-altitude cell of this station, it will switch back to this cell, causing increased latency and decreased rate, seriously affecting user perception.

[0047] In order to make the purpose, technical solutions and advantages of this application more clear, the following further describes this application in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.

[0048] It should be understood that the specific embodiments described herein are merely used to explain the present application and are not intended to limit the present application. In the description of the present application, the description with reference to the terms "one embodiment", "some embodiments", "example", "specific example", or "some examples" etc. means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the present application. In this specification, the schematic representations of the above terms are not necessarily directed to the same embodiment or example.

In addition, those skilled in the art can combine and combine the different embodiments or examples described in this specification and the features of the different embodiments or examples, unless they contradict each other.

[0049] The device access method provided in the embodiment of the present application can be applied to Figure 1 In the application environment shown. The aircraft 101 is an aircraft device used to perform business, for example, the aircraft 101 can be a drone, etc. The first air base station 102 is the base station accessed by the aircraft, and the second air base station 103 is an adjacent base station of the first control base station 102. The first air base station 102 and the second air base station 103 can be implemented as independent base stations or a base station cluster composed of multiple base stations. Optionally, when the aircraft 101 detects that the base station signal quality of the currently accessed first air base station 102 is less than the first warning value, and the base station signal quality of the second air base station 103 adjacent to the first air base station 102 is greater than the second warning value, it sends first measurement information to the first air base station; wherein the first warning value is greater than the cut-off threshold value corresponding to the first air base station, and the second warning value is less than the cut-off threshold value corresponding to the second air base station; receives a first instruction fed back by the first air base station based on the first measurement information; and based on the first instruction, maintains access to the first air base station.

[0050] In one embodiment, Figure 2 As shown, a device access method is provided, which is applied to Figure 1 Taking the flying device 101 in FIG. 1 as an example, the method includes the following steps:

[0051] S201, when it is detected that the base station signal quality of the currently connected first air-to-air base station is less than the first warning value, and the base station signal quality of the second air-to-air base station adjacent to the first air-to-air base station is greater than the second warning value, first measurement information is sent to the first air-to-air base station.

[0052] Among them, the air-to-ground base station is a base station whose wireless coverage area includes the air, and is a base station device used for communication between aircraft (such as airplanes, drones, etc.) and the ground. In the embodiment of the present application, the air-to-ground base station can be a low-altitude base station, that is, a communication base station serving the low-altitude area (usually referring to the space below 1,000 meters above the ground).

[0053] The base station signal quality of the first air-to-air base station is the quality of the signal from the first air-to-air base station received by the aircraft at its current location. The base station signal quality of the second air-to-air base station is the quality of the signal from the second air-to-air base station received by the aircraft at its current location. The first warning value is a pre-set warning value for the base station signal quality, and the first warning value is greater than the cut-off threshold value corresponding to the first air-to-air base station, used to warn the aircraft that it is about to cut off from the first air-to-air base station; the second warning value is a pre-set warning value for the base station signal quality, and the second warning value is less than the cut-off threshold value corresponding to the second air-to-air base station, used to warn the aircraft that it is about to connect to the second air-to-air base station. The first measurement information is wireless measurement data reported by the aircraft. In this embodiment of the present application, the first measurement information includes but is not limited to measurement data of the cell of the first air-to-air base station, measurement data of neighboring cells, and flight information of the aircraft, such as latitude and longitude, altitude, and speed.

[0054] The cutoff threshold corresponding to the first base station is the threshold at which the aircraft exits the first base station; the cutoff threshold corresponding to the second base station is the threshold at which the aircraft enters the second base station. In other words, if the aircraft detects that the base station signal quality of the first base station is less than the cutoff threshold, it indicates that the aircraft is about to exit the first base station. If the aircraft detects that the base station signal quality of the second base station is greater than the cutoff threshold, it indicates that the aircraft is about to enter the second base station.

[0055] It should be noted that base station signal quality can be evaluated using either the Reference Signal Received Power (RSRP) or the received signal strength. The first measurement information can be a set of data, i.e., an MR (Measurement Report), packaged in a specified format and sent to the base station after the aircraft monitors the wireless signal in real time according to the measurement rules (such as measurement object, period, and reporting conditions) configured by the first airborne base station.

[0056] The first warning value and the second warning value can be set based on the distance between the first air-to-air base station and the second air-to-air base station, the direction and coverage of the low-altitude cell main lobe of the first air-to-air base station, and the direction and coverage of the low-altitude cell main lobe of the second air-to-air base station. For example, the smaller the distance between the first air-to-air base station and the second air-to-air base station, the larger the difference between the first warning value and the second warning value.

[0057] Optionally, the flight equipment can monitor the wireless signals of the first air base station and the wireless signals of nearby air base stations (including the second air base station) in real time according to the measurement rules configured by the first air base station. When the flight equipment detects that the base station signal quality of the first air base station currently connected is less than the first warning value, and the base station signal quality of the second air base station adjacent to the first air base station is greater than the second warning value, it indicates that the flight equipment may switch from the first air base station to the second air base station. At this time, the location information of the flight equipment (for example, longitude and latitude and altitude, etc.) can be obtained from the positioning device installed on the flight equipment, and the speed and other information of the flight equipment can be obtained from the speed monitoring device installed on the flight equipment, packaged as the first measurement information, and sent to the first air base station through RRC (Radio Resource Control, RRC) signaling.

[0058] S202: Receive a first instruction fed back by a first air-to-air base station based on first measurement information.

[0059] Among them, the first instruction carries a first mobility strategy; the first mobility strategy includes a first update threshold value and a second update threshold value, the first update threshold value is the threshold value after lowering the cut-in threshold value, and the second update threshold value is the threshold value after raising the cut-in threshold value; the first instruction is used to instruct the flight equipment to communicate with the first air base station based on the first mobility strategy.

[0060] It should be noted that mobility policy refers to a series of technologies and methods for managing the continuous communication of aircraft devices during mobility. Its core goal is to ensure that when aircraft devices switch between different locations and different networks, communication is not interrupted, service quality is not significantly affected, and resource utilization efficiency is optimized. In the embodiment of the present application, the mobility policy includes but is not limited to the threshold value for switching out of the first air base station and the threshold value for switching in to the second air base station.

[0061] Optionally, after receiving the first measurement information sent by the aerial device, the first airborne base station determines, based on the first measurement information, whether the aerial device is located within a blind spot of the main lobe beam of the first airborne base station. If the aerial device is within the blind spot of the main lobe beam of the first airborne base station, it indicates that the aerial device is still within the coverage area of the first airborne base station. Therefore, to prevent frequent handovers of the aerial device, the handover threshold corresponding to the first airborne base station is lowered to obtain a first updated threshold, and the handover threshold corresponding to the second airborne base station is raised to obtain a second updated threshold. A first mobility policy is then generated based on the first updated threshold and the second updated threshold. A first instruction is generated based on the first mobility policy and sent to the aerial device.

[0062] Exemplarily, if the first measurement information carries flight information of the flight device, the flight information includes at least location information, such as latitude and longitude and altitude, etc., the first air-to-air base station determines that the flight device is located in the blind spot area of the main lobe beam of the first air-to-air base station based on the location information in the flight information carried by the first measurement information of the first air-to-air base station, and then sends a first instruction to the flight device.

[0063] S203: Based on the first instruction, maintain access to the first air base station.

[0064] Optionally, after receiving the first instruction, the flight equipment can update the cut-off threshold value corresponding to the first air base station according to the first update threshold value based on the first instruction, and update the cut-off threshold value corresponding to the second air base station according to the second update threshold value, while maintaining access to the first air base station and not switching to the second air base station.

[0065] In the above device access method, upon detecting that the signal quality of the first airborne base station it is currently connected to is less than a first warning value, and the signal quality of a second airborne base station adjacent to the first airborne base station is greater than a second warning value, the aircraft sends first measurement information to the first airborne base station. Because the first warning value is greater than the cut-off threshold corresponding to the first airborne base station, and the second warning value is less than the cut-off threshold corresponding to the second airborne base station, this provides an early warning before the aircraft switches. Furthermore, the aircraft receives a first instruction fed back by the first airborne base station based on the first measurement information and, based on the first instruction, maintains access to the first airborne base station. This avoids frequent handoffs caused by interference from the second airborne base station during flight and ensures the stability of low-altitude services.

[0066] In one embodiment, if Figure 3 As shown, based on the first instruction, maintaining access to the first air base station may specifically include the following:

[0067] S301: When detecting that the base station signal quality of a first air-to-air base station is greater than a first warning value, second measurement information is sent to the first air-to-air base station.

[0068] The second measurement information is wireless measurement data reported by the aircraft, and the second measurement information includes but is not limited to flight information of the aircraft, such as location information of the aircraft at the current moment.

[0069] Optionally, if the aircraft detects that the base station signal quality of the first base station is greater than the first warning value, it indicates that the aircraft is in an area with good low-altitude 5G coverage from the first base station and is subject to minimal interference from remote low-altitude base stations (including the second base station). In this case, the aircraft can send second measurement information to the first base station via RRC signaling.

[0070] S302: Receive a second instruction fed back by the first air-to-air base station based on second measurement information.

[0071] The second instruction carries a second mobility policy, and the second mobility policy includes a hand-off threshold value and a hand-off threshold value.

[0072] Optionally, if the aircraft detects that the base station signal quality of the first air base station is greater than the first warning value, it indicates that the aircraft is in an area with good low-altitude 5G coverage of the first air base station. There is no need to determine the signal of the remote low-altitude base station, and the first air base station restores its original mobility policy for the aircraft. It should be noted that since the current aircraft accesses the first air base station based on the first mobility policy, that is, the cut-off threshold value corresponding to the first air base station has been updated to the first updated threshold value, and the cut-off threshold value corresponding to the second air base station has been updated to the second updated threshold value, it is necessary to reset the first updated threshold value to the initial cut-off threshold value, and reset the second updated threshold value to the initial cut-off threshold value.

[0073] Therefore, the first airborne base station needs to generate a second mobility strategy according to the cut-off threshold value and the cut-off threshold value, and then generate a second instruction and send the second instruction to the flying device.

[0074] S303: Communicate with the first air base station based on the second mobility strategy.

[0075] Optionally, after the flight device resets the handoff threshold value corresponding to the first airborne base station and the handoff threshold value corresponding to the second airborne base station based on the second mobility policy, it will continue to communicate with the first airborne base station.

[0076] In this embodiment, when the flight equipment detects that the base station signal quality of the first air base station is greater than the first warning value, it sends second measurement information to the first air base station. The first air base station feeds back a second instruction to the flight equipment based on the second measurement information, ensuring that the flight equipment can restore the initial mobility strategy in time when it is in a low-altitude area with a good network of the first air base station.

[0077] In one embodiment, Figure 4 As shown, a device access method is provided, which is applied to Figure 1 The following steps are described using the first air base station 102 currently connected by the flying device in FIG. 1 as an example:

[0078] S401: Receive first measurement information sent by an aircraft.

[0079] Among them, the first measurement information is sent when the flight equipment detects that the base station signal quality of the first air-to-air base station is less than the first warning value, and the base station signal quality of the second air-to-air base station adjacent to the first air-to-air base station is greater than the second warning value; the first warning value is greater than the cut-in threshold value corresponding to the first air-to-air base station, and the second warning value is less than the cut-in threshold value corresponding to the second air-to-air base station.

[0080] Optionally, when the flying device connected to the first air base station detects that the base station signal quality of the currently connected first air base station is less than the first warning value, and the base station signal quality of the second air base station adjacent to the first air base station is greater than the second warning value, it will send first measurement information to the connected first air base station.

[0081] S402: Based on the first measurement information, feed back a first instruction to the aircraft to instruct the aircraft to maintain access to the first airborne base station.

[0082] Among them, the first instruction carries a first mobility strategy; the first mobility strategy includes a first update threshold value and a second update threshold value, the first update threshold value is the threshold value after lowering the cut-in threshold value, and the second update threshold value is the threshold value after raising the cut-in threshold value; the first instruction is used to instruct the flight equipment to communicate with the first air base station based on the first mobility strategy.

[0083] Optionally, the first airborne base station can obtain the location information of the aerial device from the first measurement information and determine whether the aerial device is located in a blind spot of the first airborne base station's main lobe beam based on the location information. It should be noted that the blind spot of the first airborne base station's main lobe beam is an area where the first airborne base station's communication signal is poor, such as a location such as the top of the first airborne base station. The blind spot of the first airborne base station's main lobe beam can be calculated based on information such as the topography of the first airborne base station's location, signal propagation type, and base station equipment parameters using an artificial intelligence (AI) algorithm.

[0084] Furthermore, if it is determined that the flight equipment is located in the blind area of the air main lobe beam of the first air base station, the cut-out threshold value corresponding to the first air base station is lowered to obtain a first updated threshold value, and the cut-in threshold value corresponding to the second air base station is increased to obtain a second updated threshold value. Furthermore, a first mobility strategy is generated based on the first updated threshold value and the second updated threshold value, and then a first instruction is generated based on the first mobility strategy, and the first instruction is sent to the flight equipment.

[0085] Exemplarily, if the first measurement information carries flight information of the flight equipment, the flight information includes at least location information, such as latitude and longitude and altitude, etc., the first air-to-air base station determines that the flight equipment is located in the blind spot area of the main lobe beam of the first air-to-air base station based on the location information in the flight information carried by the first measurement information of the first air-to-air base station, and then sends a first instruction to the flight equipment.

[0086] In the above-mentioned device access method, after the first air base station receives the first measurement information sent by the flight equipment when it detects that the base station signal quality of the first air base station is less than the first warning value, and the base station signal quality of the second air base station adjacent to the first air base station is greater than the second warning value, the first air base station feeds back a first instruction to the flight equipment based on the first measurement information to instruct the flight equipment to maintain access to the first air base station, and the first warning value is greater than the cut-off threshold value corresponding to the first air base station, and the second warning value is less than the cut-off threshold value corresponding to the second air base station; this ensures that the switching behavior of the flight equipment can be predicted in advance, and the flight equipment can be controlled in advance to maintain access to the first air base station, thereby avoiding frequent switching of the flight equipment and improving service stability.

[0087] In one embodiment, in order to ensure the accuracy of the determined blind area, the blind area of the air main lobe beam of the first air base station can also be determined based on the base station deployment position of the first air base station and the coverage area of the air main lobe beam, as well as the location information in the sample measurement information sent by the sample device connected to the first air base station; wherein, the sample measurement information is sent by the sample device when the base station signal quality of the first air base station is less than the first warning value, and the base station signal quality of the second air base station is greater than the second warning value.

[0088] For example, a sample device can be controlled to fly within the coverage area of a first airborne base station, continuously collecting the base station signal quality of the first airborne base station and the base station signal quality of the second airborne base station during flight. Furthermore, if the base station signal quality of the first airborne base station is detected to be less than a first warning value and the base station signal quality of the second airborne base station is greater than a second warning value, the location information of the sample device is obtained, and sample measurement information including the location information is sent to the first airborne base station. It should be noted that the number of sample devices is generally multiple to ensure data accuracy. The first airborne base station adjusts handover parameters for sample devices located in blind spots covered by the main lobe of the first airborne base station's top. When a sample device flies into this area, it promptly receives instructions to adjust its mobility strategy to maintain service within the low-altitude cell of the first airborne base station as much as possible. For each sample measurement data collected during this process, the first airborne base station integrates the sample measurement information from each sample device and trains each sample measurement data using an AI algorithm to mark and generate blind spots covered by the main lobe of the first airborne base station's top.

[0089] In addition, based on the sample measurement information of the sample device described above, a first warning value and a second warning value can also be determined based on the sample measurement information. Specifically, to prevent the aircraft from leaving the coverage area of the first air-to-air base station between receiving the first measurement information of the aircraft and sending the first instruction to the aircraft, the first warning value and the second warning value need to be set within a reasonable range. Specifically, in this process, the sample device can be controlled to simulate the flight behavior of the aircraft during the execution of its business. If it is detected that the base station signal quality of the first air-to-air base station is less than the first warning value and the base station signal quality of the second air-to-air base station is greater than the second warning value, the position information and speed of the aircraft are sent to the first base station. Based on the position information and speed, the time when the aircraft leaves the coverage area of the first air-to-air base station is determined. Furthermore, the first warning value and the second warning value are comprehensively calculated.

[0090] In one embodiment, if Figure 5 As shown, when the aircraft flies to the range where the communication signal of the first airborne base station is relatively good, the first airborne base station also needs to control the aircraft to restore the mobility strategy, which may specifically include the following:

[0091] S501: Receive second measurement information sent by an aircraft.

[0092] The second measurement information is sent when the flight equipment detects that the base station signal quality of the first air-to-air base station is greater than the first warning value.

[0093] Optionally, when the flight device detects that the base station signal quality of the first air-to-air base station is greater than the first warning value, the flight device may send second measurement information to the first air-to-air base station through RRC signaling.

[0094] S502: Feedback a second instruction to the flight equipment based on the second measurement information.

[0095] The second instruction carries a second mobility policy, which includes a cut-off threshold value and a cut-off threshold value; the second instruction is used to instruct the flight device to communicate with the first air base station based on the second mobility policy.

[0096] Optionally, when the aircraft reaches a range where the communication signal from the first airborne base station is relatively strong, it is necessary to control the aircraft to revert to the initial mobility policy. It should be noted that since the aircraft currently accesses the first airborne base station based on the first mobility policy, i.e., the handoff threshold corresponding to the first airborne base station has been updated to the first updated threshold, and the handoff threshold corresponding to the second airborne base station has been updated to the second updated threshold, it is necessary to reset the first updated threshold to the initial handoff threshold, and reset the second updated threshold to the initial handoff threshold. Therefore, the first airborne base station needs to generate a second mobility policy based on the handoff threshold and handoff threshold, and then generate a second instruction and send the second instruction to the aircraft.

[0097] In this embodiment, when the flying device detects that the base station signal quality of the first air-to-air base station is greater than the first warning value, it sends second measurement information to the first air-to-air base station. The first air-to-air base station feeds back a second instruction to the flying device based on the second measurement information, ensuring that the initial mobility strategy can be restored in time when the flight reaches a range where the communication signal of the first air-to-air base station is relatively good.

[0108] S608: The first airborne base station feeds back a second instruction to the flying device based on the second measurement information.

[0109] The second instruction carries a second mobility policy, which includes a cut-off threshold value and a cut-off threshold value; the second instruction is used to instruct the flight device to communicate with the first air base station based on the second mobility policy.
