[0002] With the rapid development and maturity of civil drone technology, drone applications have gradually expanded from line-of-sight applications to beyond-line-of-sight applications, and from the consumer field to multiple industries such as inspection, agriculture, logistics, and security. In order to ensure the safe flight of low-altitude drones, it is necessary to establish an effective low-altitude drone traffic management system to achieve monitoring, identification, control, and command of drones. However, the traditional mobile communication network aims to meet the communication needs of people. The antenna of the mobile base station is facing the ground, so the air coverage is insufficient and cannot meet the communication needs of low-altitude drones.

[0003] With the development of low-altitude economy, 5G network is the best choice for low-altitude interawareness fusion services. However, when ground base stations communicate with low-altitude base stations, due to the wide coverage of low-altitude base station cells, there is a one-to-many relationship between low-altitude base station cells and ground base station cells, which makes the maintenance of neighboring cell relationships of low-altitude base station cells complicated, resulting in resource consumption.

Taking running on a mobile terminal as an example, Figure 1 1 is a hardware structure block diagram of a mobile terminal of a method for collaborative management of a low-altitude base station and a ground base station according to an embodiment of the present application. Figure 1 As shown, the mobile terminal may include one or more ( Figure 1 Only one is shown in the figure) a processor 102 (the processor 102 may include but is not limited to a processing device such as a microprocessor MCU or a programmable logic device FPGA) and a memory 104 for storing data, wherein the mobile terminal may also include a transmission device 106 and an input / output device 108 for communication functions. It can be understood by those skilled in the art that Figure 1 The structure shown is for illustration only and does not limit the structure of the mobile terminal.

[0024] The memory 104 can be used to store computer programs, for example, software programs and modules of application software, such as the computer program corresponding to the method for collaborative management of low-altitude base stations and ground base stations in the embodiment of the present application. The processor 102 executes various functional applications and data processing by running the computer program stored in the memory 104, that is, to implement the above method. The memory 104 may include a high-speed random access memory, and may also include a non-volatile memory, such as one or more magnetic storage devices, flash memory, or other non-volatile solid-state memory. In some instances, the memory 104 may further include a memory remotely arranged relative to the processor 102, and these remote memories may be connected to the mobile terminal via a network.

[0025] The transmission device 106 is used to receive or send data via a network. The specific example of the above network may include a wireless network provided by a communication provider of the mobile terminal. In one example, the transmission device 106 includes a network adapter (Network Interface Controller, referred to as NIC), which can be connected to other network devices through a base station so as to communicate with the Internet. In one example, the transmission device 106 can be a radio frequency (RF) module, which is used to communicate with the Internet wirelessly.

[0026] In this embodiment, a method for collaborative management of low-altitude base stations and ground base stations is provided, which is applied to low-altitude base stations. Figure 2 is a flow chart of a method for collaborative management of low-altitude base stations and ground base stations according to an embodiment of the present application, such as Figure 2 As shown, the process includes the following steps:

[0027] Step S201: receiving a cell change request initiated by an aircraft device, and acquiring a preset cell correspondence table and flight status information of the aircraft device from a low-altitude resource pool based on the cell change request.

[0028] In the embodiment of the present application, a low-altitude resource pool may be pre-established, and the low-altitude resource pool may include multiple low-altitude base stations and low-altitude base station cells corresponding to the multiple low-altitude base stations. For example, at least one low-altitude resource pool may be established according to the low-altitude base stations corresponding to the flight routes of the flight equipment.

[0029] As an example, the correspondence between low-altitude base station cells and ground base station cells can be determined in advance based on the matching relationship between low-altitude base stations and ground base stations in the low-altitude resource pool, and a cell correspondence table can be generated. The low-altitude base stations in the low-altitude resource pool can maintain a preset cell correspondence table.

[0030] As an example, when a low-altitude base station in a low-altitude resource pool receives a cell change request initiated by a flying device, the low-altitude base station can obtain a preset cell correspondence table and flight status information of the flying device from the low-altitude resource pool based on the cell change request.

[0031] In an exemplary embodiment, before receiving the cell change request initiated by the flight device, the method further includes:

[0032] Step S200, based on the matching relationship between the low-altitude base station and the ground base station, and the transmission relationship between the ground base station and the adjacent base stations of the ground base station, a communication link is established with the adjacent base stations of the low-altitude base station to form the low-altitude resource pool.

[0033] As an example, before receiving a cell change request initiated by a flying device, the low-altitude base station can establish a communication link with the adjacent base stations of the low-altitude base station based on the matching relationship between the low-altitude base station and the ground base station, and the transmission relationship between the ground base station and the adjacent base stations of the ground base station to form a low-altitude resource pool.

[0034] For example, Figure 3 is a low-altitude base station pooling networking diagram according to an embodiment of the present application, such as Figure 3 As shown in the figure, the coverage area of ​​low-altitude base station cells is relatively wide, and they cannot be interconnected physically. Low-altitude base stations and ground base stations can establish a pairing relationship in advance, and then establish a communication link between low-altitude base stations based on the transmission relationship between ground base stations (such as baseband processing units (BBU)), and form a low-altitude resource pool between low-altitude base stations.

[0035] There are many ways to build a low-altitude resource pool, such as:

[0036] Method 1: Based on the physical configuration of the low-altitude base station and the ground base station, a communication link is established between the low-altitude base stations. Method 1 can include two scenarios:

[0037] 1) Co-location scenario of low-altitude base stations and ground base stations

[0038] Low-altitude base stations can carry a "low-altitude" logo, and low-altitude base stations and ground base stations can transmit together. Low-altitude base stations can rely on ground base stations to establish Xn transmission.

[0039] Assume that the low-altitude base station that initiates the establishment of a low-altitude resource pool is the source low-altitude base station, and the ground base station that transmits together with the source low-altitude base station is the source ground base station. The source low-altitude base station can establish a low-altitude resource pool with at least one target low-altitude base station, and the target low-altitude base station transmits together with the target ground base station.

[0040] When the source low-altitude base station forms a low-altitude resource pool with the target low-altitude base station, it can initiate a request for the target ground base station to establish a communication link based on the co-transmission ground base station. The request can carry the address of the source low-altitude base station.

[0041] The target ground base station receives the request from the low-altitude base station to establish a communication link, and forwards the request to the target low-altitude base station; the target low-altitude base station responds to the request from the low-altitude base station to establish a communication link, and sends a response message carrying the address of the target low-altitude base station to the target ground base station.

[0042] The target ground base station receives the response message carrying the address of the target low-altitude base station and forwards it to the ground base station that transmits together with the source low-altitude base station, and the ground base station that transmits together with the source low-altitude base station sends it to the source low-altitude base station.

[0043] The source low-altitude base station can receive a response message carrying the address of the target low-altitude base station, and establish a communication link with the target low-altitude base station based on the address of the target low-altitude base station in the response message, thereby forming a low-altitude resource pool.

[0044] 2) Low-altitude base stations and ground base stations are not co-located

[0045] Low-altitude base stations can carry a "low-altitude" identification. Low-altitude base stations and ground base stations do not share transmission. Low-altitude base stations can initiate requests to establish Xn communication links to other low-altitude base stations and ground base stations respectively.

[0046] It is assumed that the low-altitude base station that initiates the establishment of a low-altitude resource pool is a source low-altitude base station, and the other low-altitude base stations serve as target low-altitude base stations for establishing a low-altitude resource pool.

[0047] The source low-altitude base station can initiate a request to establish an Xn communication link to the target low-altitude base station and the ground base station respectively. After receiving the request message to establish the Xn communication link, the target low-altitude base station or the ground base station can initiate an Xn communication link establishment response, and then establish a communication link between the low-altitude base station and the ground base station or a communication link between low-altitude base stations.

[0048] If the target low-altitude base station or ground base station does not initiate an Xn communication link establishment response, that is, the communication link between the low-altitude base station and the ground base station or the communication link between the low-altitude base stations cannot be established, a path can also be established through the core network. The method of establishing a path through the core network is an existing technical solution and will not be repeated in detail in the embodiments of the present application.

[0049] Method 2: Establishing communication links between low-altitude base stations based on service triggering

[0050] If the flying device fails to switch cells in time when moving between low-altitude base station cells, the service will fail, which will trigger the service to be re-established to the target low-altitude base station cell. The target low-altitude base station cell can initiate a context request to the source low-altitude base station, and trigger the target low-altitude base station to establish an Xn communication link with the source low-altitude base station by re-establishing the context.

[0051] Among them, the establishment of Xn links between low-altitude base stations can be a dynamic maintenance process. Xn links can be established or released according to the business to achieve flexible adjustment of dynamic resources.

[0052] In an exemplary embodiment, step S200 may specifically include the following steps:

[0053] Step S2001, sending a low-altitude base station pooling request to a ground base station that matches the low-altitude base station, so that the ground base station sends the low-altitude base station pooling request to the adjacent base stations of the ground base station according to the low-altitude base station pooling request and the transmission relationship between the ground base station and the adjacent base stations of the ground base station;

[0054] Step S2002: forwarding the low-altitude base station pooling request to an adjacent base station of the low-altitude base station that matches the adjacent base station of the ground base station through the adjacent base station of the ground base station;

[0055] Step S2003, when the adjacent base station of the low-altitude base station responds to the low-altitude base station pooling request, receiving the low-altitude base station pooling response message sent by the adjacent base station of the low-altitude base station through the adjacent base station of the ground base station, and forwarding the low-altitude base station pooling response message to the ground base station;

[0056] Step S2004: receiving the low-altitude base station pooling response message sent by the ground base station, establishing a communication link with an adjacent base station of the low-altitude base station, and forming the low-altitude resource pool.

[0057] As an example, the low-altitude base station that initiates the establishment of a low-altitude resource pool can be used as a source low-altitude base station, and the low-altitude base stations in the low-altitude resource pool except the source low-altitude base station can be used as target low-altitude base stations.

[0058] For example, when the source low-altitude base station wants to initiate the establishment of a low-altitude resource pool, the source low-altitude base station can send a low-altitude base station pooling request to the source ground base station that matches the source low-altitude base station.

[0059] The source ground base station can receive the low-altitude base station pooling request, and based on the low-altitude base station pooling request and the transmission configuration of its own interface, send the low-altitude base station pooling request to the adjacent base stations of the ground base stations that are communicatively connected to the source ground base station.

[0060] As an example, the source ground base station can determine the adjacent base stations of the ground base station that have a transmission relationship with the source ground base station based on the transmission configuration of its own interface. When the source ground base station receives the low-altitude base station pooling request, the source ground base station can send the low-altitude base station pooling request to the adjacent base stations of the ground base station based on the low-altitude base station pooling request and the transmission relationship between the ground base station and the adjacent base stations of the ground base station.

[0061] The adjacent base station of the ground base station may receive the low-altitude base station pooling request and forward the low-altitude base station pooling request to a target low-altitude base station that matches the adjacent base station of the ground base station.

[0062] The target low-altitude base station may receive the low-altitude base station pooling request and send a low-altitude base station pooling response message to the adjacent base stations of the ground base station.

[0063] The adjacent base stations of the ground base station can receive the low-altitude base station pooling response message and forward it to the source ground base station, so that the source ground base station feeds back the low-altitude base station pooling response message to the source low-altitude base station.

[0064] The source low-altitude base station may receive the low-altitude base station pooling response message, so that communication links are established between the various low-altitude base stations to form a low-altitude resource pool.

[0065] As an example, the low-altitude base station pooling request sent by the source low-altitude base station and the low-altitude base station pooling response message sent by the target low-altitude base station can respectively carry information that needs to be transmitted between low-altitude base stations, such as flight trajectory, service monitoring status and other information.

[0066] In an exemplary embodiment, before step S2001, the following may also be included:

[0067] Determining a base station configuration mode of the low-altitude base station and the ground base station; the base station configuration mode includes a co-station configuration of the low-altitude base station and the ground base station;

[0068] In the case where the low-altitude base station and the ground base station are co-located, sending a matching request to the ground base station, so that the ground base station responds to the matching request;

[0069] The matching response sent by the ground base station is received, a matching relationship between the low-altitude base station and the ground base station is established, and the matching relationship is maintained.

[0070] As an example, before initiating the establishment of a low-altitude resource pool, the low-altitude base station can establish a matching relationship with the corresponding ground base station based on the base station configuration mode of the low-altitude base station and the ground base station.

[0071] As an example, when the base station configuration mode of the low-altitude base station and the ground base station is a co-site configuration, the low-altitude base station can send a matching request to the ground base station co-site configured with the low-altitude base station, wherein the matching request can carry information such as the low-altitude base station ID, the low-altitude base station IP address, the base station type, etc.

[0072] As an example, a ground base station co-located with a low-altitude base station can receive a matching request and send a matching response to the low-altitude base station based on the low-altitude base station ID, low-altitude base station IP address, base station type and other information in the matching request. The matching response can carry information such as the ground base station ID, the ground base station IP address, and the base station type.

[0073] As an example, the low-altitude base station can receive a matching response sent by a ground base station, and establish a matching relationship with the ground base station based on information such as the ground base station ID, the ground base station IP address, and the base station type in the matching response.

[0074] As an example, the low-altitude base station side can save the matching relationship between the low-altitude base station and the ground base station, and maintain the matching relationship between the low-altitude base station and the ground base station.

[0075] In an exemplary embodiment, the base station configuration mode further includes a non-co-site configuration of the low-altitude base station and the ground base station, and before step S2001, it may also include:

[0076] In the case where the low-altitude base station and the ground base station are not co-located, sending a link establishment request to the ground base station and an adjacent base station of the ground base station respectively;

[0077] Upon receiving a link establishment response sent by the ground base station or an adjacent base station of the ground base station, a communication link is established with the ground base station or an adjacent base station of the ground base station, and the ground base station or the adjacent base station of the ground base station that sends the link establishment response is determined as the ground base station that matches the low-altitude base station.

[0078] As an example, when the base station configuration mode of the low-altitude base station and the ground base station is a non-co-site configuration, it is necessary to first establish a communication connection between the low-altitude base station and the corresponding ground base station.

[0079] As an example, the low-altitude base station can send link establishment requests to the ground base station and the adjacent base stations of the ground base station respectively, wherein the link establishment request can carry information such as the low-altitude base station ID, the low-altitude base station IP address, the base station type, etc.

[0080] As an example, the ground base station and / or the adjacent base station of the ground base station can receive the link establishment request, and send a link establishment response to the low-altitude base station based on the low-altitude base station ID, low-altitude base station IP address, base station type and other information in the link establishment request. The link establishment response can carry information such as the ground base station ID, the ground base station IP address, the base station type and the like.

[0081] As an example, when a low-altitude base station receives a link establishment response sent by a ground base station or an adjacent base station of the ground base station, it can establish a communication link with the ground base station or the adjacent base station of the ground base station based on the ground base station ID, ground base station IP address, base station type and other information in the link establishment response of the corresponding ground base station or the adjacent base station of the ground base station, and determine the ground base station or the adjacent base station of the ground base station that sends the link establishment response as the ground base station that matches the low-altitude base station.

[0082] The following is a practical example to further illustrate the process of establishing a low-altitude resource pool.

[0083] Example 1:

[0084] Figure 4is a low-altitude base station pooling flow chart according to an embodiment of the present application, such as Figure 4 As shown,

[0085] 1. The low-altitude base station (source) initiates a low-altitude pairing request to the ground base station (pairing).

[0086] Low-altitude base stations (sources) and ground base stations (matching) can be deployed in the same site, shared transmission ring, etc. Intra-site low-altitude base stations (sources) can directly initiate low-ground pairing requests to ground base stations (matching), and inter-site low-altitude base stations (sources) and ground base stations can initiate one-to-one or one-to-many pairings through request / response.

[0087] 2. The ground base station (pairing) initiates a response based on the low-ground pairing matching request.

[0088] The intra-station ground base station (pairing) can respond directly, and the inter-station can initiate a response after establishing transmission with the low-altitude base station (source).

[0089] The low-altitude base station (source) can establish a low-ground pairing relationship after receiving the response and maintain the low-ground pairing relationship.

[0090] 3. The low-altitude base station (source) initiates a low-altitude basic pooling request to the successfully paired ground base station (match).

[0091] 4. The ground base station (matching) base station receives the low-altitude base station pooling request and initiates a low-altitude base station pooling request to the associated ground base station (relay) based on its own Xn transmission configuration.

[0092] 5. The ground base station (relay) receives the low-altitude base station pooling request and forwards the low-altitude base station pooling request to the low-altitude base station (target).

[0093] If the ground base station (relay) is paired with the low-altitude base station (target), the ground base station (relay) can directly forward the low-altitude base station pooling request to the low-altitude base station (target); if the ground base station (relay) is not paired with the low-altitude base station (target), repeat the pairing process of steps 1-2.

[0094] 6. The low-altitude base station (target) base station receives the low-altitude base station pooling request, generates a low-altitude base station pooling response message based on the low-altitude base station pooling request, and sends the low-altitude base station pooling response message to the ground base station (relay).

[0095] 7. The ground base station (relay) receives the low-altitude base station pooling response message and forwards it to the ground base station (matching).

[0096] 8. The ground base station (pairing) receives the low-altitude base station pooling response message and feeds back the low-altitude base station pooling response message to the low-altitude base station (source).

[0097] In an exemplary embodiment, it also includes:

[0098] In the case where the flying device fails to switch cells, receiving a request for re-establishing a UE context sent by an adjacent base station of the low-altitude base station; the request for re-establishing a UE context carries a transmission address of the adjacent base station of the low-altitude base station;

[0099] In response to the request for re-establishing the UE context, and based on the transmission address of the adjacent base station of the low-altitude base station, a communication link is established with the adjacent base station of the low-altitude base station to form the low-altitude resource pool.

[0100] As an example, when the flying device fails to initiate a cell handover from a low-altitude base station cell to a neighboring cell of the low-altitude base station cell, it triggers the adjacent base station of the low-altitude base station to send a request to the low-altitude base station to re-establish the UE context, wherein the request to re-establish the UE context may carry the transmission address of the adjacent base station of the low-altitude base station.

[0101] As an example, a low-altitude base station can receive a request to re-establish the UE context and respond to the request to re-establish the UE context. Based on the transmission address of the neighboring base station of the low-altitude base station in the request to re-establish the UE context, a communication link is established with the neighboring base station of the low-altitude base station to form a low-altitude resource pool.

[0102] In an exemplary embodiment, before acquiring a preset cell correspondence table and flight status information of a flight device from a low-altitude resource pool based on the cell change request, the method further includes:

[0103] Based on the base station configuration mode, the low-altitude base station cells in the low-altitude resource pool are matched with the ground base station cells, and a mapping relationship between the low-altitude base station cells and the ground base station cells is established.

[0104] As an example, the low-altitude base station cells and the ground base station cells in the low-altitude resource pool can be matched in advance according to the configuration mode in which the low-altitude base station and the ground base station are co-located or the configuration mode in which the low-altitude base station and the ground base station are not co-located, and a mapping relationship between the low-altitude base station cells and the ground base station cells can be established.

[0105] For example, if the low-altitude base station and the ground base station are co-located, the mapping relationship between the low-altitude base station cell and the ground base station cell can be directly established. If the low-altitude base station and the ground base station are not co-located, the mapping relationship between the low-altitude base station cell and the ground base station cell can be established based on the engineering parameters of the low-altitude base station and the ground base station, such as the base station corresponding cell information, base station longitude and latitude information, base station azimuth information, base station downtilt information, satellite information, etc., flight equipment service measurement information, etc.

[0106] As an example, a cell correspondence table may be generated based on a mapping relationship between low-altitude base station cells and ground base station cells.

[0107] In the embodiment of the present application, by establishing a low-altitude resource pool, low-altitude base station cells are interconnected, making the maintenance between low-altitude base station cells and neighboring cells of low-altitude base station cells simpler.

[0108] Step S202: determine the neighboring cell information of the low-altitude base station cell according to the preset cell correspondence table.

[0109] For example, Figure 5 is a schematic diagram of a correspondence table between low-altitude base station cells and ground base station cells according to an embodiment of the present application, such as Figure 5 As shown, the low-altitude base station corresponding to the low-altitude base station cell 1 can determine the corresponding ground base station cell and the neighboring cell corresponding to the ground base station cell from the cell correspondence table.

[0110] In an exemplary embodiment, the preset cell correspondence table includes a mapping relationship between low-altitude base station cells and ground base station cells; step S202 may specifically include:

[0111] Step S2021, obtaining neighboring cell information of a ground base station cell from a ground base station paired with the low-altitude base station;

[0112] Step S2022: Determine the neighboring cell information of the low-altitude base station cell according to the mapping relationship between the low-altitude base station cell and the ground base station cell and the neighboring cell information of the ground base station cell.

[0113] As an example, the low-altitude base station can obtain the neighboring area information of the ground base station cell from the ground base station paired with the low-altitude base station. The paired ground base station can send the neighboring area information of the paired ground base station cell to the low-altitude base station. The low-altitude base station can determine the neighboring area information of the low-altitude base station cell based on the mapping relationship between the low-altitude base station cell and the ground base station cell in the preset cell correspondence table and the neighboring area information of the ground base station cell.

[0114] For example, Figure 6 is a schematic diagram of the relationship between the low-altitude base station cell and the ground base station cell according to an embodiment of the present application, such as Figure 6 As shown, when the low-altitude base station receives a cell change request from an aircraft device, it can automatically update the neighboring cell relationship of the low-altitude base station cell according to the obtained neighboring cell information of the low-altitude base station cell, and send a received neighboring cell measurement control message to the aircraft device. Among them, the neighboring cells can include co-frequency neighboring cells, hetero-frequency neighboring cells, and inter-system neighboring cells.

[0115] In the embodiment of the present application, the neighboring area information of the ground base station cell is obtained through the ground base station, and then the neighboring area information of the low-altitude base station cell is determined based on the mapping relationship between the ground base station cell and the low-altitude base station cell, thereby giving full play to the network efficiency of the ground base station.

[0116] Step S203: adjusting the working state of the neighboring cells of the low-altitude base station cell according to the neighboring cell information of the low-altitude base station cell and the flight state information.

[0117] The low-altitude base station in the embodiment of the present application can identify the flight status and flight trajectory of the flying equipment, and can adjust the working status of the neighboring cells of the low-altitude base station cell according to the flight status and flight trajectory of the flying equipment.

[0118] As an example, Figure 7 Schematic diagram of the relationship between the low-altitude base station and the ground base station according to an embodiment of the present application, such as Figure 7 As shown, the neighboring cell information of the low-altitude base station cell may include neighboring cell weight information, and the low-altitude base station cell may dynamically adjust the working status of the neighboring cells of the low-altitude base station cell according to the neighboring cell weight information.

[0119] As an example, the working state may include a sleep state, such as shallow sleep and deep sleep. According to the flight status information of the flight equipment, the sleep state of neighboring cells of different low-altitude base station cells can be dynamically adjusted, thereby achieving energy saving and consumption reduction.

[0120] As an example, shallow sleep is a sleep state that can be awakened in real time, and deep sleep is a sleep state that takes a long time to wake up, which has the best energy saving effect.

[0121] For example, Figure 8 is a schematic diagram of energy-saving state of a low-altitude base station cell according to an embodiment of the present application, referring to Figure 7 , Figure 8 Within the first-level adjacent range, that is, the closer adjacent low-altitude base stations can adopt shallow sleep, and within the second-level adjacent range or above, the adjacent low-altitude base stations can adopt deep sleep.

[0122] As an example, flight status information may include flight speed information, flight altitude information, etc. If the flight speed of the flying device is relatively fast, the low-altitude base station can initiate a neighboring cell acquisition request to the first-level, second-level, third-level, etc. neighboring base stations with different weights based on the flight speed information or the flight altitude information to obtain more neighboring cell information.

[0123] In the embodiment of the present application, by acquiring the neighboring cell information of the low-altitude base station cell, dynamic adjustment of the working state of the low-altitude base station cell can be achieved to maximize energy saving.

[0124] The following is an example to further illustrate the process of obtaining neighboring cell information.

[0125] Example 2:

[0126] Fig. 9According to the flowchart of obtaining neighboring cell information in the embodiment of the present application, the ground base station can be divided into a first-level ground base station, a second-level ground base station, a third-level ground base station, etc. according to the configuration relationship between the low-altitude base station and the ground base station. Among them, the first-level ground base station can be a base station matching the low-altitude base station (source), such as Fig. 9 As shown:

[0127] 1. The low-altitude base station (source) initiates a low-ground relationship request to the first-level ground base station;

[0128] When a low-altitude base station (source) detects a request to access or switch cell services, it can initiate a low-ground relationship request to the first-level ground base station. The first-level ground base station can merge the low-ground neighboring area relationships of the ground base stations and then feedback to the low-altitude base station (source).

[0129] 2. The low-altitude base station (source) can determine whether it is necessary to initiate a low-altitude neighbor relationship request to the secondary ground base station based on the flight speed, flight trajectory and business status of the flight equipment.

[0130] When the secondary ground base station receives a low-altitude neighboring area relationship request initiated by the low-altitude base station (source), the secondary ground base station merges the low-altitude neighboring area relationships of the secondary ground base station and feeds them back to the low-altitude base station (source).

[0131] 3. The low-altitude base station (source) determines whether a larger range of low-altitude neighboring area relationships is needed based on the flight speed, flight trajectory and business status of the equipment.

[0132] If necessary, a low-lying neighbor relation request can be initiated to the third-level ground base station.

[0133] The third-level ground base station can merge the low-altitude neighboring area relations of the third-level ground base stations based on the low-altitude neighboring area relation request and then feed back to the low-altitude base station (source).

[0134] In the embodiment of the present application, a cell change request initiated by a flight device is received through a low-altitude base station, and a preset cell correspondence table and the flight status information of the flight device are obtained from a low-altitude resource pool based on the cell change request; the neighboring cell information of the low-altitude base station cell is determined according to the preset cell correspondence table; and the working state of the neighboring cell of the low-altitude base station cell is adjusted according to the neighboring cell information of the low-altitude base station cell and the flight status information. The low-altitude base station cells are interconnected through the low-altitude resource pool, making the maintenance of the neighboring cell relationship of the low-altitude base station cells simpler, and the working state of the low-altitude base station cell can be dynamically adjusted based on the obtained neighboring cell information of the low-altitude base station cell, so as to maximize energy saving.
