[0003] The embodiments of the present disclosure relate to the field of communications, and in particular, to a method, electronic device, and medium for collaborative management of low-altitude base stations and ground base stations. Background Art

[0004] With the rapid development and maturity of civilian drone technology, drone applications have gradually expanded from line-of-sight to beyond-line-of-sight (BLOS) applications, and from the consumer sector to multiple industries such as inspection, agriculture, logistics, and security. To ensure the safe flight of low-altitude drones, an effective low-altitude drone traffic management system is needed to enable monitoring, identification, control, and command of drones. However, traditional mobile communication networks are designed to facilitate human-to-human communication. Mobile base station antennas face the ground, resulting in insufficient aerial coverage and a failure to meet the communication needs of low-altitude drones.

[0005] With the development of the low-altitude economy, 5G networks are the optimal choice for low-altitude telepresence 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. This makes maintaining neighbor relationships for low-altitude base station cells complex and results in resource consumption.

[0028] In this embodiment, a method for collaborative management of a low-altitude base station and a ground base station is provided, which is applied to a low-altitude base station. FIG2 is a flow chart of the method for collaborative management of a low-altitude base station and a ground base station according to an embodiment of the present disclosure. As shown in FIG2 , the process includes the following steps:

[0029] Step S201: receiving a cell change request initiated by an aircraft, and acquiring a preset cell correspondence table and flight status information of the aircraft from a low-altitude resource pool based on the cell change request.

[0030] In the embodiments of the present disclosure, a low-altitude resource pool may be pre-established, which 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 based on the low-altitude base stations corresponding to the flight routes of the aircraft.

[0031] 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.

[0032] 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.

[0033] In an exemplary embodiment, before receiving a cell change request initiated by an aircraft, the method further includes:

[0034] 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.

[0035] 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.

[0036] For example, Figure 3 is a diagram of a low-altitude base station pooling network according to an embodiment of the present disclosure. As shown in Figure 3, the coverage area of ​​a low-altitude base station cell is relatively wide, and physical interconnection is not possible. A pairing relationship can be established between low-altitude base stations and ground base stations in advance. Then, based on the transmission relationship between ground base stations (such as baseband processing units (BBUs)), a communication link can be established between the low-altitude base stations to form a low-altitude resource pool between the low-altitude base stations.

[0037] There are many ways to build a low-altitude resource pool, such as:

[0038] Method 1: Establishing a communication link between low-altitude base stations based on the physical configuration of the low-altitude base station and the ground base station. Method 1 can include two scenarios:

[0039] 1) Co-location of low-altitude base stations and ground base stations

[0040] Low-altitude base stations can carry a "low-altitude" identifier, 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.

[0041] 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.

[0042] 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.

[0043] 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.

[0044] 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, which then sends it to the source low-altitude base station.

[0045] 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.

[0046] 2) Low-altitude base stations and ground base stations are not co-located

[0047] Low-altitude base stations can carry a "low-altitude" identifier. Low-altitude base stations and ground base stations do not transmit together. Low-altitude base stations can initiate requests to establish Xn communication links to other low-altitude base stations and ground base stations respectively.

[0048] It is assumed that the low-altitude base station that initiates the establishment of the low-altitude resource pool is the source low-altitude base station, and the other low-altitude base stations serve as the target low-altitude base stations for establishing the low-altitude resource pool.

[0049] 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 the low-altitude base stations.

[0050] 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 here in the embodiments of the present disclosure.

[0051] Method 2: Establishing communication links between low-altitude base stations based on service triggering

[0052] If a flying device fails to switch cells in a timely manner while moving between low-altitude base station cells, service failure will occur, triggering service re-establishment 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. By re-establishing the context, the target low-altitude base station triggers the establishment of an Xn communication link with the source low-altitude base station.

[0053] 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, thereby realizing flexible adjustment of dynamic resources.

[0054] In an exemplary embodiment, step S200 may specifically include the following steps:

[0055] Step S2001: Send 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;

[0056] 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;

[0057] 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;

[0058] Step S2004: Receive the low-altitude base station pooling response message sent by the ground base station, establish a communication link with the adjacent base station of the low-altitude base station, and form the low-altitude resource pool.

[0059] As an example, the low-altitude base station that initiates the establishment of the low-altitude resource pool can be used as the 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 the target low-altitude base stations.

[0060] For example, when a source low-altitude base station wants to initiate the establishment of a low-altitude resource pool, the source low-altitude base station may send a low-altitude base station pooling request to a source ground base station that matches the source low-altitude base station.

[0061] 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 station that are communicatively connected to the source ground base station.

[0062] 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, it 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.

[0063] 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.

[0064] 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 adjacent base stations of the ground base station.

[0065] 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.

[0066] The source low-altitude base station may receive the low-altitude base station pooling response message, so that communication links are established between the low-altitude base stations to form a low-altitude resource pool.

[0067] 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.

[0068] In an exemplary embodiment, before step S2001, the following steps may also be included:

[0069] 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-site configuration of the low-altitude base station and the ground base station;

[0070] 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;

[0071] Receive the matching response sent by the ground base station, establish a matching relationship between the low-altitude base station and the ground base station, and maintain the matching relationship.

[0072] 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.

[0073] 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.

[0074] As an example, a ground base station co-located with a low-altitude base station can receive a matching request and, based on the low-altitude base station ID, IP address, base station type, and other information in the matching request, send a matching response to the low-altitude base station. The matching response can carry information such as the ground base station ID, IP address, and base station type.

[0075] 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, ground base station IP address, and base station type in the matching response.

[0076] 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.

[0077] 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. Before step S2001, the following steps may also be included:

[0078] In a case where the low-altitude base station and the ground base station are not co-located, sending link establishment requests to the ground base station and an adjacent base station of the ground base station respectively;

[0079] 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.

[0080] 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.

[0081] As an example, the low-altitude base station can send link establishment requests to the ground base station and the adjacent base station of the ground base station respectively, where 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.

[0082] 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, ground base station IP address, base station type and so on.

[0083] 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.

[0084] The following is an example to further illustrate the process of establishing a low-altitude resource pool.

[0085] Example 1:

[0086] FIG4 is a flow chart of low-altitude base station pooling according to an embodiment of the present disclosure. As shown in FIG4 ,

[0087] 1. The low-altitude base station (source) initiates a low-ground pairing request to the ground base station (pairing).

[0088] Low-altitude base stations (sources) and ground base stations (matching) can be deployed in the same site and on the same transmission ring. An intra-site low-altitude base station (source) can directly initiate a low-ground pairing request to a ground base station (matching). Inter-site low-altitude base stations (sources) and ground base stations can initiate one-to-one or one-to-many pairings through a request / response method.

[0089] 2. The ground base station (pairing) initiates a response based on the low-ground pairing matching request.

[0090] 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).

[0091] The low-altitude base station (source) may establish a low-ground pairing relationship after receiving the response and maintain the low-ground pairing relationship.

[0092] 3. The low-altitude base station (source) initiates a low-altitude basic pooling request to the successfully paired ground base station (match).

[0093] 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.

[0094] 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).

[0095] 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.

[0096] 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).

[0097] 7. The ground base station (relay) receives the low-altitude base station pooling response message and forwards it to the ground base station (matching).

[0098] 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).

[0099] In an exemplary embodiment, the present invention further comprises:

[0100] In the case where the flying device fails to switch cells, receiving a request for re-establishing a UE context sent by a neighboring base station of the low-altitude base station; the request for re-establishing a UE context carries a transmission address of the neighboring base station of the low-altitude base station;

[0101] 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.

[0102] 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 re-establish the UE context to the low-altitude base station, wherein the request to re-establish the UE context can carry the transmission address of the adjacent base station of the low-altitude base station.

[0103] 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 adjacent base station of the low-altitude base station in the request to re-establish the UE context, it establishes a communication link with the adjacent base station of the low-altitude base station to form a low-altitude resource pool.

[0104] In an exemplary embodiment, before obtaining the preset cell correspondence table and the flight status information of the flight equipment from the low-altitude resource pool based on the cell change request, the method further includes:

[0105] 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.

[0106] 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.

[0107] For example, if a low-altitude base station and a ground base station are co-located, a 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, a mapping relationship between the low-altitude base station cell and the ground base station cell can be established based on the working parameters of the low-altitude base station and the ground base station, such as base station corresponding cell information, base station latitude and longitude information, base station azimuth information, base station downtilt information, satellite information, etc., and flight equipment service measurement information.

[0108] 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.

[0109] In the disclosed embodiment, 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 the low-altitude base station cells simpler.

[0110] Step S202: Determine the neighboring cell information of the low-altitude base station cell according to the preset cell correspondence table.

[0111] For example, Figure 5 is a schematic diagram of the correspondence table between low-altitude base station cells and ground base station cells according to an embodiment of the present disclosure. As shown in Figure 5, 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 area corresponding to the ground base station cell from the cell correspondence table.

[0112] 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:

[0113] Step S2021: Obtain neighboring cell information of the ground base station cell from the ground base station paired with the low-altitude base station;

[0114] 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.

[0115] 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.

[0116] For example, Figure 6 is a schematic diagram of the relationship between low-altitude base station cells and ground base station cells according to an embodiment of the present disclosure. As shown in Figure 6, when the low-altitude base station receives a cell change request from an aircraft, it can automatically update the neighbor relationship of the low-altitude base station cell based on the obtained neighbor cell information of the low-altitude base station cell and send a received neighbor cell measurement control message to the aircraft. Neighboring cells can include same-frequency neighboring cells, different-frequency neighboring cells, and inter-system neighboring cells.

[0117] In the disclosed embodiment, 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.

[0118] Step S203: Adjust the working state of the neighboring cell of the low-altitude base station cell according to the neighboring cell information of the low-altitude base station cell and the flight status information.

[0119] The low-altitude base station in the embodiment of the present disclosure 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.

[0120] As an example, Figure 7 is a schematic diagram of the relationship between the low-altitude base station and the ground base station according to an embodiment of the present disclosure. As shown in Figure 7, the neighboring area information of the low-altitude base station cell may include neighboring area weight information. The low-altitude base station cell can dynamically adjust the working status of the neighboring area of ​​the low-altitude base station cell based on the neighboring area weight information.

[0121] 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 the neighboring cells of different low-altitude base station cells can be dynamically adjusted, thereby achieving energy saving and consumption reduction.

[0122] 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.

[0123] For example, Figure 8 is a schematic diagram of the energy-saving state of a low-altitude base station cell according to an embodiment of the present disclosure. Referring to Figures 7 and 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.

[0124] As an example, flight status information may include flight speed information, flight altitude information, etc. If the flight speed of the flight equipment is 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 flight altitude information to obtain more neighboring cell information.

[0125] In the disclosed embodiment, by obtaining 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, thereby maximizing energy saving.

[0126] The following further illustrates the process of obtaining neighboring cell information through an example.

[0127] Example 2:

[0128] FIG9 is a flowchart of obtaining neighboring cell information according to an embodiment of the present disclosure. According to the configuration relationship between the low-altitude base station and the ground base station, 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., wherein the first-level ground base station can be a base station matched with the low-altitude base station (source), as shown in FIG9 :

[0129] 1. The low-altitude base station (source) initiates a low-ground relation request to the first-level ground base station;

[0130] When a low-altitude base station (source) detects a request to access or switch a cell service, it can initiate a low-altitude relationship request to the first-level ground base station. The first-level ground base station can merge the low-altitude neighboring area relationships of the ground base station and then feedback to the low-altitude base station (source).

[0131] 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.

[0132] 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).

[0133] 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.

[0134] If necessary, a low-lying neighbor relation request can be initiated to the third-level ground base station.

[0135] 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 the merged low-altitude neighboring area relations to the low-altitude base station (source).

[0136] In the disclosed embodiment, a cell change request initiated by an aircraft is received by a low-altitude base station. Based on the cell change request, a preset cell correspondence table and the flight status information of the aircraft are obtained from a low-altitude resource pool. Neighboring cell information of the low-altitude base station cell is determined based on the preset cell correspondence table. Based on the neighboring cell information of the low-altitude base station cell and the flight status information, the operating status of the neighboring cells of the low-altitude base station cell is adjusted. The low-altitude resource pool enables interconnection between low-altitude base station cells, making it easier to maintain neighboring cell relationships of low-altitude base station cells. Furthermore, based on the obtained neighboring cell information of the low-altitude base station cells, the operating status of the low-altitude base station cells can be dynamically adjusted to maximize energy saving.
