BRIEF DESCRIPTION OF THE DRAWINGS
[0020] The accompanying drawings, which are incorporated in and constitute a part of this specification, illustrate embodiments consistent with the present disclosure and, together with the description, serve to explain the principles of the present disclosure.
[0021] In order to more clearly illustrate the embodiments of the present disclosure or the technical solutions in the prior art, the following briefly introduces the drawings required for use in the embodiments or the description of the prior art. Obviously, for ordinary technicians in this field, other drawings can be obtained based on these drawings without any creative work.

[0023] Figure 2 A schematic diagram of the structure of a base station networking device provided in one embodiment of the present disclosure. DETAILED DESCRIPTION
[0024] In order to more clearly understand the above-mentioned objectives, features and advantages of the present disclosure, the scheme of the present disclosure will be further described below. It should be noted that the embodiments of the present disclosure and the features therein can be combined with each other in the absence of conflict.
[0025] In the following description, many specific details are set forth to facilitate a full understanding of the present disclosure, but the present disclosure may also be implemented in other ways different from those described herein; it is obvious that the embodiments in the specification are only part of the embodiments of the present disclosure, rather than all of the embodiments.
[0026] With the increasing use of drones in various environments, the adaptability of drone-borne base stations to these scenarios is gaining increasing attention. Currently, in the relevant technologies, under ideal conditions, drone-borne base stations can maintain their operational capabilities at all times, and mobile devices covered by the base stations can stably access the core network through the base stations. However, in actual application scenarios, drone-borne base stations rarely operate in ideal environments and are prone to failures. Existing drone-borne base station networking methods cannot meet the stable connectivity requirements of target mobile stations served by drone-borne base stations in non-ideal environments.
[0027] To address the above issues, the present disclosure provides a base station networking method, wherein a backup base station obtains the network parameters of the current working base station and the control plane context of the target mobile device served by the working base station. Based on the control plane context, the backup base station receives the uplink signal of the target mobile device, thereby ensuring that the wireless link between the backup base station and the target mobile device is in an available state. The backup base station then performs beamforming based on the uplink signal to direct the beam of the backup base station's antenna array toward the target mobile device. When the working base station loses its operating capability, the backup base station activates the wireless link, network parameters, and control plane context to enable the target mobile device to transmit data through the backup base station. The above technical solution enables the mobile device served by the working base station to be covered by the beam of the backup base station's antenna array when the working base station is operating. This allows the backup base station to be quickly activated to provide services to the mobile device when the working base station loses its operating capability, achieving efficient and smooth base station handover, reducing the impact of the working base station's inability to operate on the target mobile device, and allowing the target mobile device to maintain a continuous connection with the base station, thereby ensuring a continuous and stable connection between the target mobile device and the core network. The disclosed solution can meet the stable connection requirements of target mobile devices served by base stations carrying drones in non-ideal environments.
[0028] Figure 1 This is a flow chart of a base station networking method provided in accordance with an embodiment of the present disclosure. The base station networking method can be executed by a base station networking device provided in accordance with an embodiment of the present disclosure. The base station networking device can be implemented using software and / or hardware and can be integrated on a base station.
[0029] like Figure 1 As shown, the base station networking method may include the following steps:
[0030] Step 101: Acquire network-side parameters of a working base station and a control plane context of a target mobile device served by the working base station.
[0031] For example, two base stations can be set up for the same area (such as a cell). One base station can initially provide services for the covered area and be referred to as the working base station, while the other base station can be referred to as the backup base station. Mobile devices located within the area can be referred to as target mobile devices, and there can be multiple target mobile devices.
[0032] In the disclosed embodiment, the working base station first provides services to all target mobile devices within its coverage area. The standby base station does not provide services to the target mobile devices simultaneously with the working base station. Instead, while the working base station is providing services to the target mobile devices, the standby base station obtains network-side parameters of the working base station and parameters of the target mobile devices served by the working base station. The network-side parameters may include, but are not limited to, parameters such as the working base station's IP address displayed on the core network, gateway address, and device name. The parameters of the target mobile devices may include, but are not limited to, a list of target mobile devices and the control plane context of each target mobile device on the list.
[0033] For example, the control plane context of the target mobile device may include, but is not limited to, the target mobile device's radio link control parameters, media access control parameters, and physical layer channel control parameters. These parameters enable accurate reception of uplink signals sent by the target mobile device, thereby restoring the radio link between the backup base station and the target mobile device. Specifically, the specific parameters corresponding to the environmental detection channel and random access preamble signal within the physical layer channel control parameters serve as the basis for calculating beamforming parameters.
[0034] Step 102: Based on the context of the control plane, receive an uplink signal from the target mobile device, so that the wireless link between the standby base station and the target mobile device is in an available state.
[0035] In the embodiment of the present disclosure, based on the context of the control plane of the target mobile device, the backup base station can receive uplink signals such as uplink channel detection reference signals and uplink random access preamble signals from the target mobile device. It can be understood that the uplink signal sent by the target mobile device can be received in the entire space, but only the base station with matching channel control parameters can correctly receive the uplink signal. Since the backup base station obtains the context of the control plane of the target mobile device from the working base station, that is, obtains the channel control parameters of the target mobile device, the backup base station can accurately receive the uplink signal sent by the target mobile device. The backup base station accurately receives the uplink signal sent by the target mobile device, which also ensures that the wireless link between the backup base station and the target mobile device is in an available state.
[0036] Step 103: Perform beamforming based on the uplink signal so that the beam of the antenna array of the standby base station points toward the target mobile device.
[0037] In an embodiment of the present disclosure, the backup base station can use the uplink signal received from the target mobile device to perform beamforming so that the beam of the antenna array of the backup base station continues to point to the target mobile device, thereby making the wireless link between the backup base station and the target mobile device continuously available, providing conditions for subsequent smooth switching of the backup base station.
[0038] Beamforming is a signal preprocessing technique based on antenna arrays. By adjusting the weighting coefficients of each element in the antenna array, a directional beam is generated, resulting in significant array gain. Beamforming offers significant advantages in expanding coverage, improving edge throughput, and mitigating interference. It is a commonly used technique in wireless communications. This disclosure does not elaborate on the principles behind beamforming.
[0039] In addition, in an optional implementation of the present disclosure, in order to ensure that the standby base station can be put into operation promptly and quickly when it needs to provide services to the target mobile device, the antenna of the standby base station can be kept in a powered-on state.
[0040] It should be noted that in the embodiment of the present disclosure, although the wireless link between the backup base station and the target mobile device is in an available state, the wireless link is not put into operation immediately. Instead, it serves as a backup. Before the working base station loses its working capability, the target mobile device continues to be connected to the working base station.
[0041] Step 104: In response to the working base station losing its working capability, enabling the radio link, the network side parameters and the control plane context, so that the target mobile device performs data transmission through the standby base station.
[0042] In an embodiment of the present disclosure, when the working base station loses its working capability, the backup base station can enable the wireless link between the backup base station and the target mobile device, and enable the network side parameters such as the IP address, gateway address, device name, etc. of the working base station displayed in the core network obtained from the working base station, as well as enable the control plane context of the target mobile device, so that the backup base station takes over the work of the working base station to provide services for the target mobile device and starts transmitting air interface signals and carried signaling. After that, the target mobile device can transmit data through the backup base station to achieve connection with the core network, thereby ensuring stable operation of the data link of the target mobile device.
[0043] Exemplarily, the backup base station can obtain the network side parameters of the working base station and the control plane context of the target mobile device in real time. When the backup base station does not receive the network side parameters of the working base station for more than a preset time, it can be considered that the working base station has lost its working ability. After that, the wireless link between the backup base station and the target mobile device is put into operation.
[0044] In the embodiment of the present disclosure, since the backup base station inherits the network side parameters of the original working base station and the control plane context of the target mobile device, it can ensure that the target mobile device continues to work in the service area of the backup base station without perception, realizes smooth switching of the air interface, and ensures a continuous and stable connection between the target mobile device and the core network.
[0045] In the base station networking method of the embodiment of the present disclosure, the standby base station obtains the network side parameters of the working base station and the control plane context of the target mobile device served by the working base station, and based on the control plane context, receives the uplink signal of the target mobile device, so that the wireless link between the standby base station and the target mobile device is in an available state, and performs beamforming based on the uplink signal so that the beam of the antenna array of the standby base station is directed to the target mobile device, and then, in response to the working base station losing its working ability, enables the wireless link, network side parameters and control plane context to enable the target mobile device to transmit data through the standby base station. By adopting the above technical solution, when the working base station is working, the beam of the antenna array of the standby base station is used to cover the mobile device served by the working base station, so that when the working base station loses its working ability, the standby base station can be quickly enabled to provide services to the mobile device, achieving effective and smooth switching of the base station, reducing the impact of the working base station losing its working ability on the target mobile device, and enabling the target mobile device to continue to connect with the base station, thereby ensuring a continuous and stable connection between the target mobile device and the core network.
[0046] In an optional embodiment of the present disclosure, the context of the control plane may include physical layer channel control parameters, and the physical layer channel control parameters include environment detection channel parameters and random access preamble signal parameters, so that the standby base station can receive the uplink channel detection reference signal and uplink random access preamble signal sent by the target mobile device based on the environment detection channel parameters and random access preamble signal parameters.
[0047] Furthermore, the backup device may perform beamforming using at least one of the received uplink channel sounding reference signal and the uplink random access preamble signal, so that the beam of the antenna array of the backup base station continuously points to the target mobile device.
[0048] In an optional embodiment of the present disclosure, beamforming can be performed based on the uplink channel sounding reference signal and the uplink random access preamble signal. Specifically, a channel matrix can be constructed based on the uplink channel sounding reference signal and the uplink random access preamble signal, and then the channel matrix can be subjected to singular value decomposition to obtain a beam-formed precoding base station. Then, based on the precoding matrix, the beam of the antenna array of the backup base station is controlled to point to the target mobile device.
[0049] For example, channel estimation can be performed based on the uplink channel sounding reference signal and the uplink random access preamble signal to determine the channel matrix. The channel matrix can be determined using a commonly used channel estimation method, and the present disclosure does not elaborate on the specific determination process.
[0050] It should be noted that in the embodiment of the present disclosure, the channel matrix is subjected to singular value decomposition to obtain a precoding matrix, and the beam pointing of the base station's antenna array is controlled based on the precoding matrix. These are common technologies in this field and can be implemented through currently commonly used implementation methods. This disclosure will not elaborate on this.
[0051] A heartbeat message is a message sent from a sending source to a receiving source, which allows the receiving source to determine whether the sending source has failed or terminated, and to determine when the sending source has failed or terminated. Typically, heartbeat messages are sent from the time the sending source is started until the sending source is shut down, during which time the sending source will continuously send periodic or repetitive messages. When the receiving source does not receive a heartbeat message within a certain message receiving cycle, the receiving source may assume that the sending source has been shut down, failed, or is currently unavailable. Therefore, in an optional embodiment of the present disclosure, the working base station and the standby base station can send heartbeat messages as a basis for determining whether the working base station has lost its ability to work.
[0052] Specifically, the working base station can continuously send heartbeat messages to the standby base station. When the standby base station does not receive the heartbeat message sent by the working base station for more than a preset time period, it can be determined that the working base station has lost its working ability.
[0053] Among them, the preset duration can be pre-set according to actual needs.
[0054] When the wireless link between the working base station and the target mobile device is interfered with or interrupted, the working base station will be unable to maintain the heartbeat message sent to the backup base station; or, when the working base station is a base station carried by a drone, if the drone actively leaves the area of the target mobile device due to insufficient battery life, or the drone is expelled from the area of the target mobile device by a third-party external force, the working base station will also be unable to maintain the heartbeat message sent to the backup base station. The area of the target mobile device refers to the location area of the drone when the antenna of the base station carried by the drone can cover the target mobile device. When the drone leaves the area of the target mobile device, the antenna of the base station carried by the drone cannot cover part or all of the target mobile device. When the backup base station does not receive a heartbeat message for more than a preset time, it can be considered that the working base station has lost its working ability, and then the wireless link between the backup base station and the target mobile device is activated to ensure the stable operation of the data link of the target mobile device.
[0055] In an optional embodiment of the present disclosure, the working base station and the backup base station can be carried on different drones. The working base station is the base station carried by the first drone, and the backup base station is the base station carried by the second drone. Data between the first and second drones can be exchanged via a dedicated network. The dedicated network can be a communication network implemented by drone cluster communication networking, including but not limited to wireless ad hoc networks, WiFi, Zigbee, etc.
[0056] In an embodiment of the present disclosure, the backup base station (i.e., the base station of the second drone payload) can obtain network-side parameters of the base station of the first drone payload (i.e., the working base station), the target mobile device served by the base station of the first drone payload, and the control plane context corresponding to the target mobile device through the dedicated network between the first drone and the second drone. The backup base station can obtain the above information in real time or periodically, which is not limited by the present disclosure.
[0057] When the working base station is the base station of the first drone payload and the backup base station is the base station of the second drone payload, the working base station and the backup base station move with the movement of the drones to which they belong. The first drone moves to the area of the target mobile device to provide services to the target mobile device. The second drone can move according to the preset movement conditions. When the preset movement conditions are met, the second drone moves to the area of the target mobile device, that is, the backup base station also covers the target mobile device.
[0058] Among them, the area of the target mobile device refers to the location area of the drone when the antenna of the base station carried by the drone can cover the target mobile device. When the drone leaves the area of the target mobile device, the antenna of the base station carried by the drone cannot cover part or all of the target mobile device.
[0059] Exemplarily, the preset movement condition is to move simultaneously with the working base station. Then, when the first UAV moves to the area of the target mobile device, it can be determined that the preset movement condition is currently met, and the second UAV also moves to the area of the target mobile device at the same time, so that the working base station and the backup base station cover the target mobile device at the same time.
[0060] For example, the preset movement condition is that the second UAV must move to the target mobile device area after a preset time period after the working base station moves to the target mobile device area. When the backup base station receives a prompt message indicating that the first UAV has moved to the target mobile device area, it starts a timer and obtains the timer duration in real time. When the timer duration reaches the preset duration, it can be determined that the preset movement condition is currently met, and the second UAV can be controlled to move to the target mobile device area. The prompt message can be sent by the first UAV when it moves to the target mobile device area, or it can be sent by a third-party device that tracks the first and second UAVs. When the third-party device tracks the first UAV moving to the target mobile device area, it sends a prompt message to the backup base station indicating that the first UAV has moved to the target mobile device area.
[0061] Exemplarily, the preset movement condition is receiving a movement instruction to move to the target mobile device's area. Exemplarily, the movement instruction can be sent by a first drone. After the active base station moves to the target mobile device's area, specific conditions trigger the first drone to send a movement instruction to control the movement of the backup base station. These specific conditions can include, for example, the first drone leaving the target mobile device's area or running out of battery life. After the first drone moves to the target mobile device's area, it can monitor its own status. If the first drone's battery life runs out, or if the first drone is expelled from the target mobile device's area, the first drone can send a movement instruction to a second drone. Upon receiving the movement instruction, the second drone determines that the preset movement condition is met and controls the second drone to move to the target mobile device's area. The movement instruction can also be sent by a third-party device. For example, the third-party device can receive its own status reported by the first drone. Upon receiving a status such as insufficient battery life or a malfunction of the first drone, or upon receiving a request to leave from the first drone, the third-party device can send a movement instruction to the backup base station to move to the target mobile device's area. Upon receiving the movement instruction, the backup base station controls the second drone to move to the target mobile device's area.
[0062] It should be noted that in the disclosed embodiments, the area of the target mobile device is a regional range that may include multiple locations. When the drone moves to any location within the area of the target mobile device, the base station carried by the drone can cover all target mobile devices within the area. Controlling the second drone to move to the area of the target mobile device refers to controlling the second drone to move to a target location within the area of the target mobile device. The target location may be any location within the area of the target mobile device. When the second drone moves to the target location, the antenna of the backup base station can cover the target mobile device.
[0063] In an optional embodiment of the present disclosure, the target location can be selected as a location in the area of the target mobile device that is far away from the location of the first drone. As a result, the first drone and the second drone can be separated by a sufficiently long distance to ensure that both the working base station and the backup base station can fully cover the target mobile device while minimizing the possibility that the first drone and the second drone are simultaneously affected by external forces and lose their working capabilities. In other words, it is ensured that at least one of the working base station and the backup base station is not attacked by external forces, thereby ensuring that the target mobile device can be continuously and stably connected to the core network through the base station carried by the drone.
[0064] In order to implement the above embodiments, the present disclosure further provides a base station networking device, which can be implemented using software and / or hardware and can be applied to a base station.
