[Technical Field]

[0001] The present application relates to a communication field, for example, a communication base station, a communication base station transition method, and a storage medium. [Background technology]

[0002] In wireless network construction, hardware costs are the largest expense, and base station costs account for the largest portion. From first-generation mobile communication technology (1G) networks to 5G networks, the expansion of network scale has led to an increase in the number of base stations deployed. In the 5G era, various new scenarios bring new network requirements, increasing the complexity of base stations and driving up costs. Meanwhile, new wireless communication technologies are gradually evolving from low frequencies to high frequencies. However, high-frequency bands have limitations, such as limited propagation distance and reduced coverage. Therefore, future base stations will need to be deployed more densely to achieve better signal coverage, further increasing network construction costs. Therefore, how to reduce hardware costs in wireless network construction has become an urgent issue. Summary of the Invention [Problem to be solved by the invention]

[0003] The way people work and live in modern cities creates highly regular patterns of crowd movement. For example, during working hours on weekdays, crowds gather in industrial parks, office buildings, and other workplaces within the city. After work and on weekends, they gather in residential areas, commercial areas, and leisure areas. Due to this pattern of crowd movement in densely populated cities, network construction in each area requires planning the number of base stations according to the maximum number of user accesses. Because base stations are fixedly installed, they cannot move with users or be dynamically deployed to accommodate changes in urban traffic. This design approach results in underutilization of equipment in each area at certain times and the need to respond to traffic surges at other times. For operators, underutilization of deployed equipment results in losses, and periodic surges in traffic also pose a certain risk of network congestion. [Means for solving the problem]

[0014] In one embodiment, the communication module further includes a storage module for storing the transition plan data, the transition route, and the parameters of the connection modules in each region of the communication module. Here, the transition plan refers to a periodic transition planned for the communication module. For example, the transition command can be periodically generated based on the transition plan to perform the corresponding transition operation.

[0015] In one embodiment, the first interface module includes a power supply interface, a communication interface, and a mechanical fixing interface, wherein the power supply interface is used to obtain power from the connected connection module so as to power each module in the communication module and charge the power supply module, the communication interface is used to exchange information with the connection module, and the mechanical fixing interface is used to mechanically dock and lock with the connection module.

In this embodiment, the support module provides fixed support for the communications module while performing attitude adjustment for the communications module. In this embodiment, performing attitude adjustment for the communications module refers to adjusting the pitch angle and azimuth angle of the communications module so that the second interface module of the connection module docks with the first interface module of the communications module. In this embodiment, the support module may include a hydraulic device, which drives the extension and retraction of the support structure to achieve attitude adjustment for the communications module.

In this embodiment, the communication base station 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 two ways: one is to use the rotor flight structure to provide flight driving force and rely on a power module built into the communication module to provide power, and after completing the transition and docking with a new connection module, the power supplied by the connection module charges the built-in power supply of the communication module in preparation for use in the next transition; and two is to use the air jet flight structure to provide flight driving force and rely on an external fuel storage device to provide the fuel required for flight.

In one embodiment, the mechanical locking interface of the first interface module mechanically docks with the connection module, and after the mechanical docking is completed, the connection module locks the mechanical locking interface of the first interface module to prevent the communications module from starting the flight module to perform the transition. If the mechanical locking interface of the first interface module is not locked by the connection module, the communications module can start the flight module to perform the transition upon receiving the transition command.

[0020] In one embodiment, Figure 2 is a flowchart of a communication base station transition method according to an embodiment of the present application. This embodiment can be implemented by the communication base station in the above embodiment. As shown in Figure 2, this embodiment includes steps S210 to S250.

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

[0022] The first region is the region 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 an embodiment, the transition command may be received via a wired or wireless connection. If the transition command is received wirelessly, the transition command can be acquired from a wireless signal received by an antenna module built into the communication module, and the transition can be performed. If the transition command is received via a wired connection, the transition command can be received via a communication interface connected to the connection module, and the transition can be performed. Of course, the corresponding transition command can be generated from transition plan data stored in a memory module built into the communication module, and the transition can be performed. In an embodiment, the transition target position refers to the destination to which the communication module is to transition, and the target connection module identifier refers to the identifier of the connection module to which the communication module is to establish a connection, and is the identification information of the connection module. The transition target position can be understood to be the region adjacent to the location of the connection module to which the connection provided by the communication module is to be established.

[0023] In the embodiment, the first disconnection request refers to a request to disconnect the wired connection between the connection module and the communication module in the first region, which can be understood as performing a disconnection operation on the wired connection between the communication module and the connection module. In the embodiment, after the communication module receives 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 the first disconnection request to the connection module connected thereto via the communication interface.

[0024] In S220, if the disconnection condition is met, the connection module sends first disconnection confirmation information to the communication module.

[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 this 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 have been 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.

[0027] The second region is a region where the transition target position is located. In an embodiment, the flight module in the communication module plans a flight route based on the transition target position, so as to autonomously transition the communication module to the transition target position in the second region according to the flight route.

[0028] In S240, when the communication module reaches the transition target position, the alignment identifier of the connection module corresponding to the target connection module identifier is obtained.

[0029] In an embodiment, the transition target position provides the communications module with a rough orientation of the connection module in one of the second regions, and a second alignment module in the connection module provides an alignment identifier to the communications module for more precise alignment and docking with the connection module in the second region.

[0030] In S250, the communication module adjusts the flight attitude of the communication module based on the alignment identifier to dock with the second interface module of the connection module.

[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 dock accurately 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 cleanup operation on the accessed user and data, where the cleanup operation on 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 new terminals. 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 new terminals.

[0033] In one embodiment, a communication base station transition method includes: The connection module further includes disconnecting the communication module from the first interface module, releasing the mechanical support and lock, and switching the power supply mode of the communication module from power supply by the connected connection module to power supply by the internal power module. In an embodiment, after the connection module receives the first disconnection request, the connection module disconnects the communication module from the first interface module, releases the mechanical support and mechanical lock for the communication module, and starts the internal power module of the communication module to supply power to each module in the communication module. Of course, the communication module may directly switch the power supply mode by the communication module to power supply by the internal power module and start the flight module after confirming that there is no terminal access and no data waiting to be sent or received.

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

[0035] In an embodiment, if the connection module includes an antenna module, it is also necessary to disconnect the wireless connection between the communication module and the connection 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 to it through the communication interface and activates the antenna module to intercept the response of the connection module. 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 via the antenna module. After the communication module receives the second disconnection confirmation information, it begins to perform flight transition.

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

[0037] In one embodiment, a method for transitioning a communication base station includes: The method further includes using the flight module in the communication module to adjust its position and attitude, docking with the mechanical fixing 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, connecting the power interface and the communication interface and sending first docking confirmation information to the communication module. In one 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 its position and attitude of the communication module based on the alignment identifier to dock with the mechanical fixing interface of the connection module. If the connection module includes an antenna module, when the communication module reaches the transition target position, the antenna module establishes a wireless connection with the designated connection module in the second area, and during the wireless connection establishment, they mutually verify their respective identification information to confirm that it matches 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 to establish 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 sends first docking confirmation information to the communication module, thereby confirming the wired connection between the communication module and the connection module.

[0038] In one embodiment, the connection module includes an antenna module, and before docking with the flight module in the communication module to the mechanical fixing interface of the connection module, The method further includes the communication module sending a second docking request to the connection module via a wireless channel, and when the communication module aligns with the connection module, the connection module sending second docking confirmation information to the communication module. In an embodiment, if 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 the second docking request to the connection module via a wireless channel, and after the connection module receives the second docking request, it checks the alignment status and, if it confirms alignment, sends the second docking confirmation information to the communication module via the wireless channel.

[0039] In one embodiment, after the communication module establishes a connection with the connection module in the second region, The method further includes switching the power supply mode of the communications module from power supply by the internal power supply module to power supply by the connected connection module. In an embodiment, after the communications module establishes a wired connection with the connection module, the connection module supplies wired power to the communications module via a power supply interface in the communications module. While the connection module supplies wired power to the communications module via the power supply interface in the communications module, it can also charge the power supply module in the communications module to ensure that the power supply module is as fully charged as possible.

[0040] In one embodiment, the acquisition method of the transition command includes one of the following: periodically acquiring the transition command from the transition plan data stored in the storage module, and sending the transition command from the base station management system or the network management system. In one embodiment, the communication module may periodically generate the corresponding transition command from the transition plan data stored in the storage module, or the base station management system or the network management system may monitor traffic in real time to predict traffic trends, and generate and send the corresponding transition command to the communication base station.

[0041] In one embodiment, Figure 3 is a structural block diagram of another communication base station according to an embodiment of the present application. As shown in Figure 3, the present application proposes a communication base station for transmitting, receiving, and processing wireless signals, the base station being composed of a mobile communication module and a fixed access module, the access module being capable of connecting or disconnecting with the communication module, the communication module in a first region being capable of disconnecting from the access module in the first region and flying to a second region to connect with a designated access module in the second region, the mobile communication module being capable of providing wireless network services to terminal devices after finishing connecting with the fixed access module. The base station has the following features:

[0042] The wireless communication base station proposed in this application is composed of two parts: a mobile communication module and a fixed connection module.

[0043] (1) Communication module The mobile communication module is composed of five main modules: an antenna module, a flight module, a first interface module, a power module, and a first alignment module. Here, the antenna module is composed of an antenna or an antenna array and can transmit and receive radio signals to provide wireless communication services to terminal devices. The flight module is composed of flight components and navigation components and can provide flight power and navigation to the entire communication module so that the communication module can autonomously transition from a first domain to a second domain. The first interface module is mainly composed of a power interface, a communication interface, and a mechanical fixing interface and is used for docking with a fixed connection module. The power module can be used to supply power to each module. The first alignment module can be used to implement docking between the communication module and the connection module.

[0044] In one embodiment, the communications module may further include a processing module, which has conventional signal processing functions and can process signals to be transmitted and received, including but not limited to baseband functions such as encoding, decoding, modulation, demodulation, etc., and the processing module further has conventional network functions such as radio resource allocation and scheduling, etc.

[0045] In one embodiment, the communication module may further include a storage module, which can store transition plan data, transition route data, information on each region connection module, and the like.

[0046] (2) Connection module The fixed connection module is attached to infrastructure such as a building or a base station tower, and constitutes the base of the wireless communication base station proposed in the present application, and can provide 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.

[0047] The second interface module at least includes a power supply interface, a communication interface, a mechanical fixing interface, and a backhaul interface. The power supply interface provides power to the communication module connected thereto. The communication interface is used to exchange information with the communication module, and the information exchange can be realized using an optical fiber interface, a coaxial cable interface, or other media interface capable of completing signal transmission. The mechanical fixing interface is used to provide fixed support and locking for the communication module connected thereto. The backhaul interface is used to connect to a wireless access network and realize receiving data to be transmitted and backhauling of received data. The backhaul interface can be connected to the wireless access network in a wired or wireless manner.

[0048] The second alignment module provides interface position information and alignment identifiers to the first alignment module in the flight communication module, and the communication module connects with the connection module after its attitude is adjusted by the flight module based on the interface position information and alignment identifiers provided by the second alignment module, and the support module can provide fixed support for the communication module connected to the connection module.

[0049] In one embodiment, the connection module may include an antenna module, which is composed of an antenna or an antenna array and can transmit and receive wireless signals, and can be used to exchange information before and after the connection between the communication module and the connection module is completed and disconnected, and the exchanged information includes identity identification, connection request and confirmation, etc. The antenna module can also be used to realize the access function of some terminal devices.

[0050] In one embodiment, the connection module may further include a processing module, which has conventional signal processing functions and can process signals to be transmitted and received, including but not limited to baseband functions such as encoding, decoding, modulation, demodulation, etc., and the processing module further has conventional network functions such as radio resource allocation and scheduling, etc.

[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 with 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 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. The user and data cleanup completes the transmission of pending data and the reception and transfer of pending data. It then sends a cell switching command to the accessed terminal and broadcasts a service outage notification to the cell to stop new terminal access. 1.2. After confirming that there are no terminal accesses and no data pending to be sent or received, the communication module sends a first disconnection request to the connection module connected to it via the communication interface. 1.3. After receiving the first disconnection request, the connection module checks the connection status and, if it confirms that the disconnection conditions are met, sends first disconnection confirmation information to the communication module. The disconnection conditions may include that the number of access terminals is zero and that there is no data waiting to be received or sent. 1.4. After receiving the first disconnection confirmation information from the connection module, the communication module activates its internal power supply to supply power and activates the flight module. 1.5. The communication module sends a second disconnection request to the connection module connected to it via the communication interface and activates the antenna module to intercept the response from the connection 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 second disconnection confirmation information to the communication module via 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. The sleep state means that the connection module no longer provides external services 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. The user and data cleanup completes the transmission of pending data and the reception and transfer of pending data. Then, it sends a cell switching command to the accessed terminal and broadcasts a service outage notification to the cell to stop new terminal access. 2.2: After the communication module confirms that there are no terminal accesses and no data waiting to be transmitted or received, it switches the power supply method to power supply from the internal power source and starts the flight module. 2.3: It sends a first disconnection request to the connection module connected to it via the communication interface and begins monitoring the lock status of the power interface, communication interface, and mechanical interface. 2.4: After receiving the first disconnection request, the connection module checks the connection status and, if it confirms that the disconnection condition is met, it sends first disconnection confirmation information to the communication module, then disconnects the power and communication connection with the communication module, and unlocks the mechanical lock on the communication module. The disconnection conditions may include that the number of access terminals is zero and that there is no data waiting to be received or transmitted. 2.5. The connection module enters a sleep state and re-enters a normal operating state after receiving a new active command. The sleep state means that the connection module does not provide external services to reduce power consumption. 2.6. The communication module receives the first disconnection confirmation information from 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 step: 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 positioning information from 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 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 within the area using the antenna module. During the connection establishment process, the respective identification information must be verified and confirmed to match the transition command. 4.2: After establishing a wireless connection with the access module, the communication module 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 via a wireless channel. 4.4: After receiving the first docking request, the access module checks the alignment status and, if it confirms alignment, sends a first docking confirmation message to the communication module via 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 via the flight module and sends a second docking request to the access module via a wireless channel. 4.6: After receiving the second docking request, the connection module first completes the locking and support of the mechanical interface, then connects the power interface and communication interface, activates the service function of this module, and then sends the second docking confirmation information to the communication module via 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, activates the wireless communication function of this module, and provides wireless access service to terminals within the service area.

[0065] In an embodiment of the present application, a communication base station is provided with a mobile 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 quick 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 sparse networks, improving the resource utilization rate of the base station, and reducing the hardware costs of operators.

[0066] In one embodiment, a method for 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) Reads stored transition plan data from the storage module, periodically generates transition commands based on the transition plan, and executes the transition; (2) acquires transition commands from wireless signals received by the antenna module and executes the transition; and (3) receives transition commands from a communication interface connected to the connection module and executes the transition.

[0068] If a communication base station has a malfunction, i.e., if it needs to be returned to a factory for repair, it can autonomously transition to a maintenance facility to repair the malfunctioning 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 malfunctioning communication base station autonomously transitions to the designated maintenance facility based on the received maintenance facility information. The ability 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 costs and operating costs of operators.

[0069] In one embodiment, a process for transmitting and receiving signals by a communication base station is described. In this embodiment, wireless signals need to undergo processes such as encoding and modulation before being transmitted by a radio frequency antenna, and signals received by the radio frequency antenna need to be demodulated and decoded to restore the original information. Meanwhile, the transmission and reception process also involves complex network resource allocation and scheduling issues. The processing of these data and resources needs to be performed by a single processing module. The wireless communication base station proposed 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 both the communication module and the connection module, allowing the two modules to process uplink and downlink data simultaneously through a rational division of labor.

[0071] (1) It uses a rotor flight structure to provide flight propulsion and relies on the built-in power supply of the communication module for power supply, and after completing the transition and docking with the new connection module, it charges the built-in power supply of the communication module using power supplied by the connection module to prepare for use in the next transition. (2) It uses an air jet flight structure to provide flight propulsion and relies on an external fuel storage device to provide the fuel required for flight.

In this embodiment, after the communication module and the connection module are docked, 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 transmission performance. The adjustment 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 rotating the motor to achieve the attitude adjustment of the communication module.
