This embodiment can be implemented by the communication base station in the above embodiment. As shown in FIG. 2, this embodiment includes S210 to S250.

[0021] In S210, when the communication module obtains a transition command, the communication module sends a first disconnection request to the connection module in the first region.

[0022] The first area is an area where the communication module is currently located, and the transition command includes at least a transition target position and a target connection module identifier. In the embodiment, the transition command may be received by wire or wirelessly. If the transition command is acquired wirelessly, the transition command can be acquired from a wireless signal received by an antenna module built in the communication module, and the transition can be performed. If the transition command is acquired by wire, the transition command can be received through a communication interface connected to the connection module, and the transition can be performed. Of course, the corresponding transition command can be generated from the transition plan data stored in the storage module built in the communication module, and the transition can be performed.

In the embodiment, after the communication module obtains the transition command and confirms that there is no access from the terminal and no data waiting to be sent or received, the communication module sends a first disconnection request to the connection module connected thereto via the communication interface.

[0025] In one embodiment, the disconnection conditions include: the number of access terminals is zero, and the number of data waiting to be received and the number of data waiting to be sent are zero. In the embodiment, the number of access terminals is zero, which can be understood as the number of terminals accessed by the communication module is zero, and the number of data waiting to be sent and the number of data waiting to be sent are zero, which means that the transmission of the data waiting to be sent and the reception and transfer of the data waiting to be received are completed.

[0026] In S230, the flight module in the communication module transitions to the second area based on the flight route planned according to the transition target position.

[0031] In an embodiment, the communication module adjusts the flight attitude of the communication module, i.e. adjusts the pitch angle of the communication module, based on the alignment identifier so that the communication module can precisely dock with the second interface module of the connection module.

[0032] In one embodiment, before the communication module sends a disconnection request to the connection module in the first region, the communication module further includes performing a clean-up operation on the accessed user and data, where the clean-up operation of the user and data includes: completing the transmission of data waiting to be sent and the reception and forwarding of data waiting to be received, sending a cell switching command to the accessed terminal, and broadcasting a service outage notification to the cell to stop the access of the new terminal. In an embodiment, after the communication module receives the transition command, it first cleans up the data of the accessed user, i.e., completing the transmission of data waiting to be sent and the reception and forwarding of data waiting to be received, sending a cell switching command to the accessed terminal, and broadcasting a service outage notification to the cell to stop the access of the new terminal.

Of course, after the communication module directly confirms that there is no access from the terminal and there is no data waiting to be sent or received, the power supply method by the communication module may be switched to power supply by the internal power module and the flight module may be started.

[0034] In one embodiment, the connection module includes an antenna module, and the transition method of the communication base station includes: The method further includes the communication module sending a second disconnection request to a connection module in the first region, and the connection module sending second disconnection confirmation information to the communication module by the antenna module.

In an embodiment, after the communication module receives the first disconnection confirmation information of the connection module, the communication module sends a second disconnection request to the connection module connected thereto through the communication interface, and intercepts the response of the connection module by starting the antenna module, and after receiving the second disconnection request, the connection module disconnects the wired connection with the communication module and releases the mechanical lock on the communication module, and then sends the second disconnection confirmation information to the communication module by the antenna module, and begins to perform flight transition after the communication module receives the second disconnection confirmation information.

[0036] In one embodiment, a method for transitioning a communication base station includes: During the flight process of the communication module, the antenna module receives positioning information of other base stations or satellites, and the positioning navigation component in the flight module positions the communication module in real time and corrects navigation until the communication module transitions to the transition target position. In an embodiment, to ensure that the actual flight route during the flight process of the communication module is consistent with the pre-planned flight route, the positioning navigation component in the flight module positions the communication module in real time and corrects navigation until the communication module transitions to the transition target position.

[0037] In one embodiment, a method for transitioning a communication base station includes: Further comprising: adjusting the position and attitude using the flight module in the communication module, docking with the mechanical fixed interface of the connection module, and sending a first docking request to the connection module; and after the connection module receives the first docking request, performing connection of the power interface and the communication interface, and sending a first docking confirmation information to the communication module. In an embodiment, when the communication module confirms that it has reached the transition target position based on the positioning information, it obtains an alignment identifier of the designated connection module in the second area, and the flight module in the communication module adjusts the position and attitude of the communication module based on the alignment identifier, so that it docks with the mechanical fixed interface of the connection module. If the connection module includes an antenna module, when the communication module reaches the transition target position, it establishes a wireless connection with the designated connection module in the second area through the antenna module, and in the process of establishing the wireless connection, they mutually verify each other's identification information and confirm that it is consistent with the transition command; if the connection module does not include an antenna module, when the communication module reaches the transition target position, it directly identifies the alignment identifier of the connection module designated by the navigation component in the flight module. In an embodiment, the first docking request sent from the communication module to the connection module is a request for establishing a wired connection, and after the connection module receives the first docking request, it performs a connection of the power interface and the communication interface, and confirms the wired connection between the communication module and the connection module by sending first docking confirmation information to the communication module.

[0038] In one embodiment, the connection module includes an antenna module, and before docking with the mechanical fixing interface of the connection module using the flight module in the communication module, The method further includes the communication module sending a second docking request to the connection module through a wireless channel, and when the communication module aligns with the connection module, the connection module sending a second docking confirmation information to the communication module. In an embodiment, when the connection module includes an antenna module, it is also necessary to establish a wireless connection between the communication module and a designated connection module in the second area, i.e., the communication module sends a second docking request to the connection module through a wireless channel, and after the connection module receives the second docking request, it checks the alignment state and sends the second docking confirmation information to the communication module through a wireless channel if it confirms that it is aligned.

[0051] In one embodiment, the transition of the communication module means that the communication module of the wireless communication base station presented in the present application disconnects from the connection module from the first area, then autonomously flies to the second area and connects to the designated connection module in the second area.

[0052] The transition process of the communication module can be divided into three processes: disconnection of an existing connection, flight transition, and establishment of a new connection.

[0053] First step: Disconnecting an existing connection is performed in two separate cases.

[0054] Case 1: When the connection module includes an antenna module, it can be implemented as follows.

[0055] 1.1, after receiving the transition command, the communication module first performs user and data cleanup, and the user and data cleanup completes the transmission of data waiting to be sent and the reception and transfer of data waiting to be received, and sends a cell switching command to the accessed terminal, and broadcasts a service stop notification to the cell to stop the access of the new terminal. 1.2, after the communication module confirms that there is no access of the terminal and there is no data waiting to be sent and data waiting to be received, it sends a first disconnection request to the connection module connected to it through the communication interface. 1.3, after receiving the first disconnection request, the connection module checks the connection state, and if it confirms that the connection disconnection condition is met, it sends a first disconnection confirmation information to the communication module, and the connection disconnection condition may include that the number of access terminals is zero and the data waiting to be received and the data waiting to be sent is zero. 1.4, after receiving the first disconnection confirmation information of the connection module, the communication module starts up the internal power supply to supply power and starts up the flight module. 1.5, the communication module sends a second disconnection request to the connection module connected to it through the communication interface, and intercepts the response of the connection module by starting up the antenna module. 1.6, after receiving the second disconnection request, the connection module disconnects the connection between the communication module and the first interface module, releases the mechanical lock on the communication module, and then sends the second disconnection confirmation information to the communication module through the antenna module. 1.7, the connection module enters a sleep state, and re-enters a normal operating state after receiving a new active command, where the sleep state means that the connection module no longer provides services to the outside to reduce power consumption. 1.8, after receiving the second disconnection confirmation information, the communication module begins to perform flight transition.

[0056] Case 2: If the connection module does not include an antenna module, it can be implemented as follows.

[0057] 2.1, after receiving the transition command, the communication module first performs user and data cleanup, and the user and data cleanup completes the transmission of data waiting to be sent and the reception and transfer of data waiting to be received, and sends a cell switching command to the accessed terminal, and broadcasts a service stop notification to the cell to stop the access of new terminals. 2.2, after the communication module confirms that there is no access of the terminal and there is no data waiting to be sent and waiting to be received, the communication module switches the power supply method to power supply by the internal power supply and starts the flight module. 2.3, sends a first disconnection request to the connection module connected thereto through the communication interface, and starts to monitor the lock status of the power interface, the communication interface and the mechanical interface. 2.4, after receiving the first disconnection request, the connection module checks the connection status, and if it confirms that the connection disconnection condition is met, sends a first disconnection confirmation information to the communication module, and then disconnects the power supply, communication connection with the communication module, and releases the mechanical lock on the communication module, and the connection disconnection condition may include that the number of access terminals is zero and the data waiting to be received and waiting to be sent is zero. 2.5, the connection module enters a sleep state and re-enters a normal operating state after receiving a new active command, where the sleep state means that the connection module does not provide any services to the outside in order to reduce power consumption. 2.6, the communication module receives the first disconnection confirmation information of the connection module and begins to perform flight transition after monitoring that the power interface, communication interface and mechanical interface are all unlocked.

[0058] The second process: flight transition can be performed as follows:

[0059] 3.1, the communication module determines the transition target position and the target connection module identifier according to the transition command. 3.2, the flight module in the communication module plans a flight route based on the transition target position and executes the transition according to the flight route. 3.3, during the flight process of the communication module, the antenna module receives the positioning information of other base stations or satellites until the communication module transitions into the designated area, and the positioning navigation component performs real-time positioning and yaw correction.

[0060] The third step: the establishment of a new connection by the communication module is carried out in two separate cases.

[0061] Case 1: When the connection module includes an antenna module, it can be implemented as follows:

[0062] 4.1, after the communication module confirms that it has reached the designated area based on the positioning information, it establishes a wireless connection with the designated access module in the area through the antenna module, and in the connection establishment process, it needs to verify each other's identification information and confirm that it is consistent with the transition command. 4.2, after the communication module establishes a wireless connection with the access module, it receives the alignment information of the access module, adjusts its position and attitude based on the alignment identifier of the access module, and prepares for docking. 4.3, the communication module sends a first docking request to the access module through a wireless channel. 4.4, after receiving the first docking request, the access module checks the alignment state, and if it confirms that it is aligned, sends a first docking confirmation message to the communication module through a wireless channel. 4.5, after receiving the first docking confirmation information, the communication module completes docking with the mechanical interface of the access module through the flight module, and sends a second docking request to the access module through a wireless channel. 4.6, after receiving the second docking request, the connection module first completes the locking and supporting of the mechanical interface, then performs the connection of the power interface and the communication interface, starts the service function of the module, and then sends the second docking confirmation information to the communication module through the wireless channel. 4.7, after receiving the second docking confirmation information, the communication module turns off the flight module, switches the power mode to power supply by the connection module, starts the wireless communication function of the module, and provides wireless access service to the terminal within the service area.

[0063] Case 2: If the connection module does not include an antenna module, it can be implemented as follows.

[0064] 5.1, after the communication module confirms that it has reached the designated area based on the positioning information, it identifies the alignment identifier of the connection module specified by the navigation component of the flight module. 5.2, after the communication module confirms that the alignment identifier is the target adjustment position and attitude and is aligned with the interface of the connection module, it actively docks with the interface of the connection module. 5.3, after the communication module completes the docking of the interface, the interface module of the connection module generates an active command and switches the sleeping connection module to a docking state. 5.4, the connection module first completes the locking and support of the mechanical interface, then performs the connection of the power interface and the communication interface, starts the service function of this module, and then sends docking confirmation information to the communication module through the communication interface. 5.5, after receiving the docking confirmation information, the communication module turns off the flight module, switches the power mode to power supply by the connection module, starts the wireless communication function of this module, and provides wireless access service to the terminal in the service area.

[0065] In an embodiment of the present application, a communication base station is provided with a movable communication module and a fixed connection module, and the movement of the communication module is controlled by periodically sending transition commands to the traffic in the area or the communication module, thereby enabling rapid and flexible response to changes in urban traffic, improving the wireless access quality and user experience in areas with dense human traffic, reducing the power consumption of devices in areas with vacant networks, improving the resource utilization rate of the base station, and reducing the hardware costs of operators.

[0066] In one embodiment, the method of acquiring a transition command of a communication module will be described. In the embodiment, the communication module can acquire a transition command in the following three ways.

[0067] (1) Reading stored transition plan data from the storage module, and periodically generating transition commands based on the transition plan to perform the transition; (2) Obtaining transition commands from wireless signals received by the antenna module to perform the transition; (3) Receive transition commands from a communication interface connected to the connection module to perform the transition.

[0068] If a communication base station has a fault, i.e., if it needs to be repaired by returning to a factory, it can autonomously transition to a maintenance facility to repair the faulty communication base station. Here, the location of the maintenance facility can be provided by a base station management system or a network management system, and the faulty base station autonomously transitions to a designated maintenance facility based on the received maintenance facility information. The capability of the communication base station proposed in the present application to autonomously return to a factory for repair can improve the repair efficiency of network equipment and further reduce the hardware maintenance and operation costs of the operator.

[0069] In one embodiment, the process of a communication base station transmitting and receiving a signal is described. In the embodiment, the wireless signal needs to be encoded, modulated, and other processes before being transmitted by a radio frequency antenna, and the signal received by the radio frequency antenna needs to be demodulated and decoded to restore the original information. Meanwhile, the transmission and reception process also involves complex network resource allocation and scheduling problems. The processing of these data and resources needs to be performed by one processing module. The wireless communication base station presented in this application may incorporate a processing module into the communication module to perform the above processes, or may incorporate a processing module into the connection module to perform the above processes, or may incorporate a processing module into the communication module and the connection module at the same time, and the two modules may process uplink and downlink data simultaneously through a reasonable division of labor.

In the embodiment, the wireless communication base station proposed in this application relies on the flight module to provide power during the transition process, and the flight module can provide the driving force required for flight in the following two ways:

(2) Provide flight propulsion using an air jet flight structure, rely on an external fuel storage device to provide the fuel required for flight.

[0072] In one embodiment, the adjustment of the attitude of the communication module by the connection module is described. In the embodiment, after the docking of the communication module and the connection module is completed, the connection module can actively adjust the attitude of the communication module to rotate the antenna module in the communication module in a desired direction in order to adjust the coverage area or improve the transmission performance. The adjustment method can be performed by a support module docked with the communication module. The support module may include a hydraulic device, which drives the extension and retraction of the support structure to achieve the attitude adjustment (pitch angle) of the communication module. The support module may include an electric motor, which drives the extension and retraction and rotation of the support structure by the rotation of the motor to achieve the attitude adjustment of the communication module.
