Description

TECHNICAL FIELD

[0001] The present application relates to the field of communication, in particular to a communication base station, a migration method of the communication base station and a storage medium. BACKGROUND

[0002] In the construction of a wireless network, the cost of hardware devices is the largest cost expenditure, and the cost of base stations accounts for the majority of the cost of hardware devices. From 1G network to 5G network, as the network scale expands, the investment in base stations also increases. In the 5G era, various new scenarios bring new network requirements, and the complexity of base stations also increases, accompanied by rising costs. On the other hand, new wireless communication technologies are gradually developing from low frequency to high frequency, and the propagation distance of high frequency bands is limited, and the coverage range is reduced, which makes future base stations need to be more densely deployed to achieve better signal coverage, which will further increase the cost of network construction. Therefore, how to reduce the hardware cost in the construction of a wireless network has become a problem to be solved.

[0003] The work and life style of modern cities makes the movement of people very regular. For example, during the work period on weekdays, people gather in industrial parks, office buildings and other work places in the city, and after work and on holidays, they gather in residential areas, commercial areas and entertainment places. The movement of people in dense urban areas makes the network construction in each area need to plan the number of base stations according to the maximum number of user accesses. However, the existing base stations are fixedly installed devices and cannot follow the movement of users, nor can they be dynamically deployed according to the traffic changes in the city. This design scheme makes the devices in each area have a time period that is not fully utilized, and in another time period, they need to cope with the pressure of traffic surge. For operators, the invested devices that are not fully utilized are a loss, and the periodic surge of traffic also brings a certain risk of network congestion. SUMMARY

[0007] This application provides a method for migrating a communication base station, applied to a communication base station as described in any of the above embodiments, including:

[0024] In one embodiment, the communication module further includes an antenna module; the antenna module is used to transmit and receive wireless signals and provide wireless communication services to the terminal device. In this embodiment, the antenna module may consist of an antenna or an antenna array, and can transmit and receive wireless signals. After the terminal device connects to the communication base station, wireless communication services are provided to the terminal device through the antenna module built into the communication module in the communication base station.

[0025] In one embodiment, the connection module further includes an antenna module for transmitting and receiving wireless signals. In another embodiment, the connection module may also include an antenna module to enable the connection module to establish a wireless connection with the communication module and transmit data via a wireless channel.

[0026] In one embodiment, the communication module further includes a storage module; the storage module is used to store migration plan data, migration routes, and parameters of connected modules in each region. The migration plan refers to the scheduled migration of the communication module; for example, migration instructions can be generated periodically according to the migration plan to implement corresponding migration operations.

[0027] In one embodiment, the first interface module includes: a power interface, a communication interface, and a mechanical fixing interface;

[0028] The power interface is used to obtain power from the connection module to power each module in the communication module or to charge the power module; the communication interface is used to exchange information with the connection module; the mechanical fixing interface is used for mechanical docking and locking with the connection module.

[0029] In one embodiment, the second interface module includes: a power interface, a communication interface, a mechanical fixing interface, and a return interface;

[0030] The power interface supplies power to the communication module connected to it; the communication interface exchanges information with the communication module; the mechanical fixing interface is used for mechanical docking and locking with the communication module; and the return interface connects to the wireless access network to receive data to be transmitted and to return received data. In this embodiment, the communication interface can use an optical fiber interface, a coaxial cable interface, or other media interfaces capable of signal transmission to achieve information exchange; the return interface can connect to the wireless access network via wired or wireless means.

[0031] In one embodiment, the support module is also used to adjust the attitude of the communication module. In this embodiment, the support module provides fixed support for the communication module and adjusts its attitude. Adjusting the attitude of the communication module refers to adjusting its pitch and azimuth angles to allow the second interface module in the connection module to interface with the first interface module in the communication module. In this embodiment, the support module may include a hydraulic device that drives the extension and retraction of the support structure to achieve the attitude adjustment of the communication module. The support structure may also include an electric motor that rotates to drive the extension, retraction, and rotation of the support structure to achieve the attitude adjustment of the communication module. The attitude adjustment of the communication module by the support module can correct the wireless signal coverage area of ​​the communication base station and optimize the signal quality of the area to be covered.

[0032] In one embodiment, the flight module includes one of the following structures: a rotorcraft flight structure; or a jet-powered flight structure. In this embodiment, the communication base station relies on the flight module for power during migration. The flight module can provide the driving force required for flight in two ways: first, by using a rotorcraft flight structure to provide flight driving force, powered by a built-in power module within the communication module. After completing the migration and docking with the new connection module, the power supply from the connection module is used to charge the communication module's built-in power supply for the next migration; second, by using a jet-powered flight structure to provide flight driving force, relying on an external fuel storage device to provide the fuel required for flight.

[0033] In one embodiment, the mechanical fixing interface in the first interface module is used to monitor whether the interface is locked by the connecting module. When the mechanical fixing interface is locked, the communication module cannot start the flight module to perform migration. In this embodiment, the mechanical fixing interface in the first interface module mechanically docks with the connecting module. After the mechanical docking is completed, the connecting module locks the mechanical fixing interface in the first interface module to prevent the communication module from starting the flight module to perform migration. If the mechanical fixing interface in the first interface module is not locked by the connecting module, the communication module can start the flight module to perform migration upon receiving a migration command.

[0034] In one embodiment, Figure 2 This is a flowchart illustrating a method for migrating a communication base station according to an embodiment of this application. This embodiment can be executed by the communication base station described in the above embodiments. Figure 2 As shown, this embodiment includes: S210-S250.

[0035] S210. After the communication module receives the migration instruction, the communication module sends a first disconnection request to the connection module in the first area.

[0036] The first region is the area where the communication module is currently located; the migration instruction includes at least the migration target location and the target connection module identifier. In this embodiment, the migration instruction can be received via wired or wireless means. When the migration instruction is obtained wirelessly, it can be obtained from the wireless signal received by the antenna module built into the communication module and the migration can be implemented. When the migration instruction is obtained via wired means, it can be received through the communication interface with the connection module and the migration can be implemented. Alternatively, the corresponding migration instruction can be generated from the migration plan data stored in the communication module's built-in storage module and the migration can be implemented. In this embodiment, the migration target location refers to the destination to which the communication module will migrate; the target connection module identifier refers to the identifier of the connection module to which the communication module will establish a connection, serving as the identification information of that connection module. It can be understood that the migration target location provides the communication module with the vicinity of the location of the connection module to which the connection will be established.

[0037] In this embodiment, the first disconnection request refers to a request to disconnect the wired connection between the connection module and the communication module within the first area. This can be understood as performing a disconnection operation on the wired connection between the communication module and the connection module. In this embodiment, after the communication module receives the migration instruction and confirms that no terminal is connected and there is no data to be sent or received, it sends the first disconnection request to the connection module it is connected to via the communication interface.

[0038] S220, the disconnection condition is met, and the connection module sends the first disconnection confirmation message to the communication module.

[0039] In one embodiment, the disconnection conditions include: the number of access terminals is zero; and the amount of data to be received and data to be sent is zero. In this embodiment, the number of access terminals being zero can be understood as the number of terminals connected to the communication module being zero; the amount of data to be sent and data to be forwarded being zero means that the transmission of data to be sent and the reception and forwarding of data to be received have been completed.

[0040] S230, the flight module in the communication module migrates to the second area according to the flight route planned for the migration target location.

[0041] The second region is the area where the migration target location is located. In this embodiment, the flight module in the communication module plans the flight route according to the migration target location, so that the communication module can autonomously migrate to the migration target location within the second region according to the flight route.

[0042] S240. When the communication module reaches the target migration location, obtain the alignment identifier of the connection module corresponding to the target connection module identifier.

[0043] In this embodiment, the migration target location provides the communication module with a general orientation of the connection module within a second area. To enable more precise alignment and docking with the connection module within the second area, a second alignment module within the connection module provides an alignment marker for the communication module.

[0044] S250: The communication module adjusts its flight attitude according to the alignment mark to dock with the second interface module of the connection module.

[0045] In this embodiment, the communication module adjusts its flight attitude according to the alignment mark, that is, adjusts the pitch angle of the communication module so that the communication module can accurately dock with the second interface module of the connection module.

[0046] In one embodiment, before the communication module sends a disconnect request to the connection module in the first area, the method further includes: the communication module performing a cleanup operation on the accessed users and data; wherein the cleanup operation on users and data includes: completing the transmission of data to be sent and the reception and forwarding of data to be received, sending a cell handover instruction to the already accessed terminals, broadcasting a service stop notification to the cell, and stopping new terminal access. In this embodiment, after the communication module receives the migration instruction, it first cleans up the data of the accessed users, that is, completes the transmission of data to be sent and the reception and forwarding of data to be received, sends a cell handover instruction to the already accessed terminals, broadcasts a service stop notification to the cell, and stops new terminal access.

[0047] In one embodiment, the method for migrating a communication base station further includes:

[0048] The connection module disconnects from the first interface module of the communication module and releases the mechanical support and lock;

[0049] The power supply mode of the communication module is switched from being powered by the connected connection module to being powered by the internal power module. In this embodiment, after the connection module receives the first disconnection request, it disconnects from the first interface module of the communication module and releases the mechanical support and mechanical lock on the communication module; then, it activates the internal power module of the communication module to supply power to each module in the communication module. Of course, it is also possible to directly switch the power supply mode of the communication module to the internal power module and activate the flight module after the communication module confirms that there is no terminal access and no data to be sent or received.

[0050] In one embodiment, the connection module includes an antenna module; the method for migrating a communication base station further includes:

[0051] The communication module sends a second disconnect request to the connection module in the first area;

[0052] The connection module sends a second disconnection confirmation message to the communication module through the antenna module.

[0053] In this embodiment, if the connection module includes an antenna module, the wireless connection between the communication module and the connection module also needs to be disconnected. In this embodiment, after the communication module receives the first disconnection confirmation information from the connection module, the communication module sends a second disconnection request to the connection module connected to it through the communication interface, and listens for the connection module's response by activating the antenna module. After the connection module receives the second disconnection request, it disconnects the wired connection with the communication 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. After the communication module receives the second disconnection confirmation information, it begins the flight migration.

[0054] In one embodiment, the method for migrating a communication base station further includes:

[0055] During flight, the communication module receives positioning information from other base stations or satellites via the antenna module;

[0056] The communication module is located and its navigation is corrected in real time by the positioning and navigation components in the flight module until it reaches the target location. In this embodiment, to ensure that the actual flight path of the communication module is consistent with the pre-planned flight path, the positioning and navigation components in the flight module are used to locate and correct the communication module in real time until it reaches the target location.

[0057] In one embodiment, the method for migrating a communication base station further includes:

[0058] The flight module in the communication module is used to adjust its position and attitude, dock with the mechanical fixed interface of the connection module, and send the first docking request to the connection module;

[0059] After receiving the first docking request, the connection module connects the power interface and the communication interface, and sends a first docking confirmation message to the communication module. In this embodiment, when the communication module confirms that it has reached the migration target location based on the positioning information, it obtains the alignment identifier of the designated connection module in the second area, so that the flight module in the communication module adjusts the position and attitude of the communication module according to the alignment identifier to confirm docking with the mechanical fixed interface of the connection module. It should be noted that when the connection module includes an antenna module, when the communication module reaches the migration target location, it establishes a wireless connection with the designated connection module in the second area through the antenna module, and verifies their respective identification information during the establishment of the wireless connection to confirm consistency with the migration command; when the connection module does not include an antenna module, when the communication module reaches the migration target location, it directly identifies the alignment identifier of the designated connection module through the navigation component in the flight module. In this embodiment, the first docking request sent by the communication module to the connection module is a request to establish a wired connection. After receiving the first docking request, the connection module connects the power interface and the communication interface, and sends a first docking confirmation message to the communication module to confirm the wired connection between the communication module and the connection module.

[0060] In one embodiment, the connection module includes an antenna module; prior to docking with the mechanical fixed interface between the flight module in the communication module and the connection module, it further includes:

[0061] The communication module sends a second docking request to the connection module via a wireless channel;

[0062] The communication module and the connection module are aligned, and the connection module sends a second pairing confirmation message to the communication module. In this embodiment, if the connection module includes an antenna module, a wireless connection also needs to be established between the communication module and the designated connection module in the second area. That is, the communication module sends a second pairing request to the connection module via a wireless channel, and after receiving the second pairing request, the connection module checks the alignment status. If it confirms that the alignment is complete, it sends a second pairing confirmation message to the communication module via a wireless channel.

[0063] In one embodiment, after the communication module establishes a connection with the connection module in the second area, the method further includes:

[0064] The power supply mode of the communication module is switched from being powered by its internal power module to being powered by the connected module. In this embodiment, after a wired connection is established between the communication module and the connected module, the connected module provides wired power to the communication module through the power interface in the communication module. It should be noted that while the connected module is providing wired power to the communication module through the power interface in the communication module, it can also charge the power module in the communication module to ensure that the power module is kept as fully charged as possible.

[0065] In one embodiment, the migration instruction is obtained in one of the following ways: periodically retrieved from migration plan data stored in the storage module; or issued by the base station management system or network management system. In this embodiment, the communication module can periodically generate corresponding migration instructions from the migration plan data stored in the storage module; alternatively, it can monitor traffic in real time and predict traffic trends through the base station management system or network management system to generate corresponding migration instructions and issue them to the communication base station.

[0066] In one embodiment, Figure 3 This is a structural block diagram of another communication base station provided in an embodiment of this application. For example... Figure 3 As shown, this application proposes a communication base station capable of transmitting, receiving, and processing wireless signals. The base station comprises a movable communication module and a fixed connection module. The connection module can be connected to or disconnected from the communication module. The communication module in a first area can disconnect from the connection module in the first area and fly to a second area to connect with a designated connection module in that area. After the movable communication module and the fixed connection module complete the connection, they can provide wireless network services to terminal devices. This base station has the following characteristics:

[0067] The wireless communication base station proposed in this application consists of two parts: a movable communication module and a fixed connection module.

[0068] (1) Communication module

[0069] The movable communication module consists of five main modules: an antenna module, a flight module, a first interface module, a power module, and a first alignment module. The antenna module, composed of antennas or antenna arrays, transmits and receives wireless signals and provides wireless communication services to terminal devices. The flight module, consisting of flight and navigation components, provides flight propulsion and navigation for the entire communication module, enabling it to autonomously migrate from a first area to a second area. The first interface module, mainly composed of a power interface, a communication interface, and a mechanical fixing interface, is used for interfacing with fixed connection modules. The power module supplies power to all modules. The first alignment module is used for interfacing between the communication module and the connection module.

[0070] In one embodiment, the communication module may further include a processing module, which has conventional signal processing functions and can process signals to be transmitted and received. The processing includes, but is not limited to, baseband functions such as encoding, decoding, modulation, and demodulation. The processing module also has conventional network functions, such as wireless resource allocation and scheduling.

[0071] In one embodiment, the communication module may further include a storage module, which may store migration plan data, migration route data, and connection module information for each region.

[0072] (2) Connection Module

[0073] The fixed connection module can be installed on buildings or infrastructure such as base station towers, forming the base of the wireless communication base station proposed in this application, providing fixed support and connection for the communication module. The connection module mainly consists of a second interface module, a second alignment module, and a support module.

[0074] The second interface module includes at least a power interface, a communication interface, a mechanical fixing interface, and a return interface. The power interface provides power to the communication module connected to it; the communication interface is used to exchange information with the communication module and can use a fiber optic interface, coaxial cable interface, or other medium interface capable of signal transmission to achieve information exchange; the mechanical fixing interface provides fixed support and locking for the communication module connected to it; the return interface is used to connect to the wireless access network, enabling the reception of data to be sent and the return of received data, and the return interface can connect to the wireless access network via wired or wireless means.

[0075] The second alignment module provides interface position information and alignment marks to the first alignment module in the flight communication module. Based on the interface position information and alignment marks provided by the second alignment module, the communication module adjusts its attitude and connects with the connection module. The support module provides fixed support for the communication module connected to the connection module.

[0076] In one embodiment, the connection module may include an antenna module, which consists of an antenna or an antenna array. The antenna module can transmit and receive wireless signals and can be used for information exchange between the communication module and the connection module before and after connection is established. The exchanged information includes identity verification, connection requests, and confirmations. The antenna module can also be used to implement access functions for some terminal devices.

[0077] In one embodiment, the connection module may further include a processing module, which has conventional signal processing functions and can process the signals to be transmitted and received. The processing includes, but is not limited to, baseband functions such as encoding, decoding, modulation, and demodulation. The processing module also has conventional network functions, such as wireless resource allocation and scheduling.

[0078] In one embodiment, the migration of the communication module refers to the communication module of the wireless communication base station proposed in this application disconnecting from the connection module in the first area, then autonomously flying to the second area and connecting with the designated connection module in the second area.

[0079] The migration process of the communication module consists of three steps: disconnecting the existing connection, flight migration, and establishing a new connection.

[0080] The first process: Disconnecting the existing connection is implemented in two ways:

[0081] Scenario 1: If the connection module includes an antenna module, the following steps can be taken:

[0082] Step 1.1: After receiving the migration instruction, the communication module first performs user and data cleanup; user and data cleanup includes sending the data to be sent and receiving and forwarding the data to be received, sending cell handover instructions to the connected terminals, broadcasting a service stop notification to the cell and stopping new terminal access;

[0083] Step 1.2: After confirming that no terminal is connected and there is no data to be sent or received, the communication module sends a first disconnect request to the connection module connected to it through the communication interface.

[0084] Step 1.3: After receiving the first disconnection request, the connection module checks the connection status. If it confirms that the disconnection conditions are met, it sends the first disconnection confirmation information to the communication module. The disconnection conditions may include zero access terminals and zero data to be received and sent.

[0085] Step 1.4: After receiving the first disconnection confirmation message from the connection module, the communication module activates its internal power supply and simultaneously starts the flight module;

[0086] Step 1.5: The communication module sends a second disconnect request to the connection module connected to it through the communication interface and listens for the response from the connection module by activating the antenna module;

[0087] Step 1.6: After receiving the second disconnection request, the connection module disconnects from the first interface module of the communication 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.

[0088] Step 1.7: The connection module enters a sleep state until it receives a new activation command and then re-enters normal operation. The sleep state means that the connection module no longer provides services to reduce energy consumption.

[0089] Step 1.8: After receiving the second disconnection confirmation message, the communication module begins the flight migration.

[0090] Scenario 2: If the connection module does not include an antenna module, the following steps can be taken:

[0091] Step 2.1: After receiving the migration instruction, the communication module first performs user and data cleanup; user and data cleanup includes completing the sending of data to be sent and the receiving and forwarding of data to be received, sending cell handover instructions to the already connected terminals, broadcasting a service stop notification to the cell and stopping new terminal access;

[0092] Step 2.2: After the communication module confirms that no terminal has been connected and there is no data to be sent or received, it switches the power supply mode to internal power supply and starts the flight module.

[0093] Step 2.3: Send a first disconnect request to the connection module connected to it through the communication interface, and start monitoring the locking status of the power interface, communication interface and mechanical interface;

[0094] Step 2.4: After receiving the first disconnection request, the connection module checks the connection status. If it confirms that the disconnection conditions are met, it sends the first disconnection confirmation information to the communication module, and then disconnects the power and communication connection with the communication module and releases the mechanical lock on the communication module. The disconnection conditions may include zero access terminals and zero data to be received and sent.

[0095] Step 2.5: The connection module enters a sleep state until it receives a new activation command and then re-enters the normal working state. The sleep state means that the connection module no longer provides services to the outside world in order to reduce energy consumption.

[0096] Step 2.6: After the communication module receives the first disconnection confirmation message from the connection module and detects that the power interface, communication interface and mechanical interface are all unlocked, the flight migration begins.

[0097] The second process: Flight migration can be carried out in the following steps:

[0098] Step 3.1: The communication module determines the target migration location and the target connection module identifier according to the migration instructions;

[0099] Step 3.2: The flight module in the communication module plans the flight route according to the target location and executes the migration according to the flight route;

[0100] Step 3.3: During flight, the communication module receives positioning information from other base stations or satellites via the antenna module, and the positioning and navigation components provide real-time positioning and correction of yaw until the communication module moves to the designated area.

[0101] The third process: The communication module establishes a new connection, which is implemented in two cases.

[0102] Scenario 1: If the connection module includes an antenna module, the following steps can be taken:

[0103] Step 4.1: The communication module confirms that it has arrived at the designated area based on the location information, and then establishes a wireless connection with the designated connection module in the area through the antenna module. During the connection establishment process, they need to verify each other's identity information to confirm that it is consistent with the migration command.

[0104] Step 4.2: After the communication module and the connection module establish a wireless connection, the communication module receives the alignment information from the connection module and adjusts its position and attitude according to the alignment mark of the connection module to prepare for docking.

[0105] Step 4.3: The communication module sends the first docking request to the connection module via the wireless channel;

[0106] Step 4.4: After receiving the first docking request, the connection module checks the alignment status. If it confirms that the alignment is complete, it sends the first docking confirmation message to the communication module via the wireless channel.

[0107] Step 4.5: After receiving the first docking confirmation information, the communication module uses the flight module to complete the mechanical interface docking with the connection module, and sends a second docking request to the connection module through the wireless channel.

[0108] Step 4.6: After receiving the second docking request, the connection module first completes the mechanical interface locking and support, then performs the connection of the power interface and communication interface, starts the service function of this module, and then sends the second docking confirmation information to the communication module through the wireless channel.

[0109] Step 4.7: After receiving the second docking confirmation information, the communication module shuts down the flight module, switches the power mode to connection module power supply, and starts the wireless communication function of this module to provide wireless access service to terminals in the service area.

[0110] Scenario 2: If the connection module does not include an antenna module, the following steps can be taken:

[0111] Step 5.1: The communication module confirms that it has arrived at the designated area based on the positioning information, and then identifies the alignment mark of the designated connection module through the navigation component of the flight module;

[0112] Step 5.2: The communication module adjusts its position and attitude with the alignment mark as the target, and actively docks with the interface of the connection module after confirming that the interface is aligned with the connection module.

[0113] Step 5.3: After the communication module completes the interface docking, the interface module of the connection module generates an activation command to switch the connection module from the dormant state to the docking state.

[0114] Step 5.4: The connection module first completes the mechanical interface locking and support, then performs the connection of the power interface and communication interface, starts the service function of this module, and then sends docking confirmation information to the communication module through the communication interface;

[0115] Step 5.5: After receiving the docking confirmation information, the communication module shuts down the flight module, switches the power mode to connection module power supply, and starts the wireless communication function of this module to provide wireless access service to terminals in the service area.

[0116] In this embodiment, a movable communication module and a fixed connection module are configured in the communication base station, and migration instructions are sent to the communication module through regional traffic or timed transmission to control the movement of the communication module. This allows for a quick and flexible response to changes in urban traffic flow. Furthermore, it improves the quality of wireless access and user experience in densely populated areas, while reducing equipment power consumption in idle network areas. It also improves the utilization rate of base station resources and reduces the hardware costs for operators.

[0117] In one embodiment, the method by which the communication module obtains migration instructions is described. In this embodiment, the communication module can obtain migration instructions in the following three ways:

[0118] (1) Read the stored migration plan data from the storage module and generate migration instructions periodically according to the migration plan to carry out the migration;

[0119] (2) Obtain migration instructions from the wireless signals received by the antenna module and implement the migration;

[0120] (3) Receive migration instructions from the communication interface with the connection module and perform the migration.

[0121] It should be noted that when a communication base station malfunctions and requires factory repair, it can autonomously migrate to a repair site for maintenance. The location of the repair site can be provided by the base station management system or network management system, and the malfunctioning base station autonomously migrates to the designated repair site based on the received repair site information. The autonomous factory repair capability of the communication base station proposed in this application can improve the maintenance efficiency of network equipment and further reduce the hardware maintenance and operating costs of operators.

[0122] In one embodiment, the processing procedure for transmitting and receiving signals by a communication base station is described. In this embodiment, the wireless signal needs to undergo encoding, modulation, and other processing before being transmitted by the radio frequency antenna. The signal received by the radio frequency antenna needs to be demodulated and decoded to recover the original information. Furthermore, the transmission and reception process involves complex network resource allocation and scheduling issues. The processing of these data and resources requires a processing module. The wireless communication base station proposed in this application can choose to embed a processing module in the communication module to perform the above processing, or it can embed a processing module in the connection module to perform the above processing, or it can embed a processing module in both the communication module and the connection module simultaneously. Through reasonable division of labor, uplink and downlink data can be processed simultaneously in both modules.

[0123] In one embodiment, the power drive method of the flight module is described. In this embodiment, the wireless communication base station proposed in this application relies on the flight module for power during migration, and the flight module can provide the driving force required for flight in the following two ways:

[0124] (1) The rotor-type flight structure provides flight drive, and the communication module is powered by its built-in power supply. After the migration is completed and the new connection module is connected, the power supply of the connection module is used to charge the built-in power supply of the communication module for the next migration.

[0125] (2) It adopts a jet-powered flight structure to provide flight propulsion and relies on an external fuel storage device to provide the fuel required for flight.

[0126] In one embodiment, the adjustment of the communication module's attitude by the connection module is described. In this embodiment, after the communication module and the connection module have docked, in order to adjust the coverage area or improve transmission performance, the connection module can actively adjust the attitude of the communication module, causing the antenna module on the communication module to rotate to the desired direction. This adjustment can be accomplished through a support module docked with the communication module. The support module may include a hydraulic device, which drives the support module to extend and retract to achieve attitude adjustment (pitch angle) of the communication module. Alternatively, the support module may include an electric motor, whose rotation drives the extension, retraction, and rotation of the support module to achieve attitude adjustment of the communication module.
