Description

Technical Field

[0001] This application relates to the field of wireless technology, and in particular to a neighbor cell configuration method, apparatus, device, and readable storage medium. Background Technology

[0002] In related technologies, the configuration of satellite-based base stations is generally based on the neighbor cell configuration scheme of current terrestrial 4G / 5G networks. This means that all ground neighbor cells adjacent to the satellite's ground waveband are assigned to the satellite-based base station. However, due to the high-speed movement of satellites, the ground area covered by the satellite-based base station changes rapidly, causing the neighbor cell relationship between the satellite-based base station and the terrestrial network to change with the satellite's movement. Furthermore, because the satellite's coverage area is extremely large, typically with a single waveband radius of tens to thousands of kilometers, while the coverage radius of a terrestrial 4G / 5G cell is generally within a few hundred meters to a few kilometers, the number of ground cells overlapping or adjacent to the satellite's ground waveband coverage and the terrestrial communication network is very large, generally reaching hundreds to tens of thousands of ground cells. If the satellite-based base station needs to store tens of thousands of ground neighbor cell lists, it will not only occupy a large amount of storage space, but also incur significant processing overhead when searching for neighbor cell information.

However, it should also be understood that determining B based on A does not mean determining B solely based on A; B can also be determined based on A and / or other information.

[0069] To enable those skilled in the art to better understand the embodiments of this application, the following description will be provided first.

[0070] In 4G / 5G mobile communication networks, after a base station is powered on, the Operation and Maintenance Center (OMC) configures a list of neighboring cells for each base station based on network planning information. The base station saves these neighboring cell lists. During real-time communication, the base station notifies terminals in the coverage area to perform neighboring cell measurements via broadcast or UE measurement messages so that cell reselection or handover can be performed.

[0071] In an integrated space-ground network, low-Earth orbit (LEO) satellite networks and terrestrial mobile communication networks provide coordinated coverage. When a terminal uses LEO satellite communication, there may be scenarios where the terminal needs to switch to the terrestrial network due to the terminal's mobility, satellite network load, or service reasons. Before the terminal switches over, the LEO satellite base station needs to configure a measurement command for the terminal. The measurement command contains information about the neighboring ground cells that need to be measured. The terminal completes the neighboring cell measurement and sends the measurement report to the LEO satellite base station. Based on the measurement report, the LEO satellite base station configures relevant handover messages for the terminal, and the terminal initiates the handover process to the terrestrial cell.

[0072] like Figure 1 As shown, for low-Earth orbit satellite systems, the ground area covered by satellite base stations changes rapidly due to the high-speed movement of the satellites, causing the neighboring cell relationships between satellite base stations and terrestrial networks to change with the satellite's movement. Meanwhile, for integrated space-ground networks, the satellite coverage area is extremely large, typically with a single wavelength radius of tens to thousands of kilometers, while the coverage radius of terrestrial 4G / 5G cells is generally within a few hundred meters to a few kilometers. Therefore, the number of overlapping or adjacent terrestrial cells between satellite-covered terrestrial wavelengths and terrestrial communication networks is very large, generally reaching hundreds to tens of thousands of terrestrial cells. If a satellite base station needs to store tens of thousands of neighboring cell lists, it will not only occupy a large amount of storage space for the satellite base station, but also incur significant processing overhead when searching for neighboring cell information. Meanwhile, in order to facilitate the switching of terminals from satellite to terrestrial 5G / 4G networks, the satellite base station needs to configure ground neighbor cell information for the terminal. According to the existing technology, since the satellite base station does not have the location information of the ground terminal and the ground neighbor cells, if a large number of neighbor cell lists are configured for the terminal, it will bring great signaling overhead and measurement burden to the terminal. If only a small number of neighbor cell information is configured for the terminal, it will cause the terminal to be unable to measure accurately, thus increasing the measurement time and processing overhead, affecting the terminal's service performance and switching performance.

[0073] Existing technologies generally configure satellite-borne base stations by directly referencing the neighbor cell configuration scheme of current terrestrial 4G / 5G networks. This means that all ground neighbor cells adjacent to the satellite's ground waveband are configured for the satellite-borne base station. This method, because it does not take into account the high-speed mobility and large coverage area of ​​the satellite, results in problems such as extremely high processing overhead and extremely low processing efficiency.

[0074] The existing technical solution involves configuring the neighbor cell list of a base station through the network management system after the base station is started. This list is stored locally by the base station and used for neighbor cell configuration during terminal reselection and handover within the base station's coverage area. However, this existing solution does not consider the dynamic changes in coverage area caused by the high dynamism of low-Earth orbit satellites, nor does it account for situations where the coverage area is much larger than the coverage area of ​​a single terrestrial network cell. Configuring it using the fixed neighbor cell configuration method of terrestrial networks leads to two major problems:

[0075] (1) The base station is required to store tens of thousands of ground neighbor cells, which greatly increases the storage and processing costs of the satellite base station.

[0076] (2) Since traditional neighboring cells do not carry location information, the satellite base station cannot configure neighboring cells for terminals within the coverage area. In order to ensure the reliability of terminal measurement and handover, either the base station configures a large amount of neighboring cell information for the terminal, or configures a small amount of neighboring cell information for the terminal to perform blind testing. Both of these situations will greatly increase the amount of measurement by the terminal and the signaling load of the interaction between the terminal and the network, thus affecting the system performance.

[0077] This invention proposes a neighbor cell configuration method that combines the terminal's location information to perform targeted dynamic neighbor cell configuration, which can significantly reduce the number of ground neighbor cells of the satellite base station and the amount of neighbor cell measurement for the UE, thus improving the handover performance and service continuity of the satellite-to-ground network.

[0078] In a space-ground integrated network, there are situations where satellite coverage and terrestrial coverage overlap or are adjacent. For a space-ground integrated network, such as... Figure 2 As shown, besides the terrestrial network, the non-terrestrial network includes satellite base stations (also described as spaceborne base stations), network management, core network, gateway station, and satellite-ground cooperation unit. The network management includes the Non-Terrestrial Network (NTN) Operation and Maintenance Center (OMC), and the core network can include the 5th Generation Core Network (5GC) of the NTN. The satellite-ground cooperation unit is used for the coordinated control of the terrestrial network and the satellite network, performing functions including satellite-ground neighbor cell configuration and management, frequency band configuration, satellite-ground frequency coordination, and satellite-ground mobility enhancement. The satellite-ground cooperation unit connects to the terrestrial network management or terrestrial base stations via the network and to the spaceborne base stations via the gateway station. The satellite-ground cooperation unit can obtain terrestrial cell list information through the terrestrial network management, including cell frequency points, Physical Cell Identifiers (PCIs), cell IDs, and cell location information (such as latitude and longitude coordinates). The aforementioned terrestrial network management includes the Terrestrial Network (TN) OMC.

[0079] like Figure 3 As shown in the figure, this application provides a neighbor cell configuration method applied to a satellite base station, the method including:

[0080] Step 301: Obtain the location information of the first terminal.

[0081] The satellite base station in this application embodiment can also be described as a spaceborne base station, which can be understood as a base station deployed on a satellite.

[0082] In some implementations, a satellite base station can obtain the location information of a first terminal via a location information acquisition command. This first terminal is a terminal located within the coverage area of ​​the satellite base station.

[0083] In some implementations, the aforementioned location information includes latitude and longitude information.

[0084] In some implementations, the first terminal may be a terminal that needs to initiate neighbor cell handover measurement, and the target neighbor cell for the first terminal to handover includes a terrestrial network cell.

[0085] Step 302: Based on the positioning information of the first terminal, send a first message to the first network element. The first message is used to request the acquisition of the ground neighbor cell list information corresponding to the first location. The distance between the location of the neighbor cell in the ground neighbor cell list information and the first location is less than a first preset distance. The first location is the location determined according to the positioning information of the first terminal. The first network element includes a satellite-ground cooperation unit or a non-terrestrial network NTN operation and maintenance center (OMC).

[0086] In some embodiments of this application, the satellite base station determines, based on the load and coverage area of ​​the satellite network, the terminal's Quality of Service (QoS) requirements, the terminal's direction of movement, etc., that the terminal needs to initiate a neighbor cell handover measurement, and the terminal's handover neighbor cell needs to include a terrestrial network neighbor cell. In this case, the satellite base station sends a first message to the first network element based on the positioning information of the first terminal.

[0087] In some embodiments of this application, the first preset distance may be pre-agreed or pre-set, and the value of the first preset distance may be set according to requirements.

[0088] In some implementations, the first message mentioned above can be a ground neighbor cell list request message.

[0089] Step 303: Receive a second message sent by the first network element, the second message including the ground neighbor cell list information corresponding to the first location.

[0090] In some implementations, the second message can be a neighbor cell configuration message.

[0091] After receiving the first message, the first network element selects a neighboring cell whose distance from the first location is less than a first preset distance as a neighboring cell in the ground neighboring cell list.

[0092] Step 304: Send a switching measurement message to the first terminal based on the ground neighbor list information.

[0093] In some implementations, the handover measurement message includes the ground neighbor cell list information. The handover measurement message is used to instruct the terminal to perform handover measurements on the cells in the ground neighbor cell list information.

[0094] In this embodiment, the satellite base station obtains the location information of a first terminal; based on the location information of the first terminal, it sends a first message to a first network element, the first message being used to request the acquisition of a ground neighbor cell list information corresponding to a first location; it receives a second message sent by the first network element, the second message including the ground neighbor cell list information; and according to the ground neighbor cell list information, it sends a handover measurement message to the first terminal. In this scheme, the satellite base station configures the ground neighbor cell list information of the first terminal based on the first location corresponding to the first terminal, which can significantly reduce the number of ground neighbor cells of the satellite base station and the amount of neighbor cell measurement required by the terminal, thereby effectively reducing the storage space of the satellite base station for storing ground neighbor cells and the processing overhead of the satellite base station when searching for neighbor cell information.

[0095] In this embodiment of the application, the first message includes the first location.

[0096] By carrying the first location in the first message, the first network element can select appropriate ground neighbor cell list information based on the first location, for example, selecting neighbor cells around the first location as neighbor cells in the neighbor cell list.

[0097] In this embodiment of the application, the first message also includes coverage area information corresponding to the first location;

[0098] The coverage area information is used to indicate the area range where the neighboring cells in the ground neighboring cell list information are located.

[0099] For example, the coverage area information is used to indicate the length in the x and y directions of the latitude and longitude coordinate system centered at the first location.

[0100] Here, by indicating the coverage area information, neighbor cell selection can be performed within the coverage area corresponding to the coverage area information.

[0101] In the embodiments of this application, the first terminal includes at least one terminal within the coverage area of ​​the satellite base station, the first location includes the location information of each terminal within the first terminal, and the first message is used to request to obtain the ground neighbor list information corresponding to the location information of each terminal within the first terminal.

[0102] Alternatively, the first terminal may include at least one group of terminals within the coverage area of ​​the satellite base station, the first location may include common location information of each group of terminals, and the first message may be used to request a list of ground neighboring cells corresponding to the common location information of each group of terminals within the first terminal, wherein each group of terminals includes at least one terminal, and the distance between terminals within the same group of terminals is less than a second preset distance, and the common location information of each group of terminals is calculated based on the location information of the same group of terminals.

[0103] In this embodiment, the ground neighbor cell list information can be obtained at the terminal granularity or at the terminal group granularity. Terminals within the same terminal group correspond to the same ground neighbor cell list information.

[0104] In some embodiments of this application, when the first terminal includes at least one group of terminals within the coverage area of ​​the satellite base station, the area range indicated by the coverage area information is larger than the first area range, where the first area range is the area range where the terminals of the same group are located. Based on this coverage area information, the first network element can know the distribution range of the terminal group, and thus can selectively select neighboring ground cells.

[0105] When obtaining ground neighbor list information at the terminal group granularity, the aforementioned first location can be the center location of each group of terminals, that is, the aforementioned public positioning information is the center location of each group of terminals.

[0106] Specifically, the satellite base station, based on the location information received from the first terminal, groups adjacent terminals and determines a common location information (i.e., common positioning information) for each group. This common location information is then used to request a list of neighboring ground cells from the satellite-ground cooperation unit for that group of terminals. Terminal grouping and determining common location information can employ clustering methods. Based on the received latitude and longitude information of each terminal, adjacent terminals are grouped together, and the coordinates of the center of each adjacent terminal in the group are calculated. If multiple groups of adjacent terminals exist, common location information is generated for each group separately. Figure 4 As shown, the position of the dot (e.g., the latitude and longitude value of the point) represents the common location information of the group of terminals. Obtaining a unified list of ground neighboring cells for a group of adjacent terminals can reduce the amount or size of messages when the satellite base station interacts with the OMC or satellite-ground cooperation unit to exchange neighboring cell information.

[0107] Assume the location information of the aforementioned terminals is represented by location points. If the first message includes location information for multiple location points, each location point can be the location corresponding to a single terminal or a group of terminals. This location information can be latitude and longitude information, such as... Figure 5As shown, the first message includes a message header and n position coordinates arranged in order, such as position 1 coordinate, position 2 coordinate, ..., position n coordinate, where n is a positive integer.

[0108] like Figure 5 As shown, the first message also includes coverage area information corresponding to n location points, such as the area size of location 1, the area size of location 2, ..., the area size of location n. This area size can be the length in the x and y directions of the latitude and longitude coordinate system centered on the location point.

[0109] Here, by indicating the coverage area information, neighbor cell selection can be performed within the coverage area corresponding to the coverage area information.

[0110] In some implementations, the second message includes at least one list of ground neighbor cells, each corresponding to a location point in the first message. Each list of ground neighbor cells contains information about one or more neighboring cells.

[0111] The neighbor cell list information in the second message is assembled sequentially according to the location points in the first message. Each neighbor cell list contains one or more neighbor cells, and the key information of each neighbor cell includes frequency point, PCI, cell ID, etc. Figure 6 As shown, the second message includes a message header and ground neighbor list information corresponding to n location points, such as the neighbor list of location 1, the neighbor list of location 2, ..., and the neighbor list of location n.

[0112] In this embodiment of the application, the ground neighbor list information includes:

[0113] The ground neighbor list information includes: information on at least one neighboring cell;

[0114] Alternatively, the ground neighbor list information may include information about at least one neighboring cell, as well as the relative position information of each neighboring cell to the first location.

[0115] The aforementioned first position can be the position of a single terminal or a common position of a group of terminals.

[0116] In some embodiments of this application, the information of neighboring cells includes, but is not limited to, at least one of frequency point, Physical Cell Identifier (PCI), and cell ID. This information can also be described as neighboring cell information.

[0117] For each neighbor cell information in the ground neighbor cell list, in addition to the key information of the neighbor cell (such as frequency point, cell ID, PCI, etc.), it can also include the location information of the neighbor cell relative to the common location point of its neighbor cell list, that is, the relative location information.

[0118] like Figure 7 As shown, the ground neighbor list information includes: neighbor 1 information, neighbor 2 information, ..., neighbor m information. The ground neighbor list information also includes the position information of neighbor 1 relative to the coordinates of the common position point, the position information of neighbor 2 relative to the coordinates of the common position point, ..., the position information of neighbor m relative to the coordinates of the common position point, where m is a positive integer.

[0119] The aforementioned relative position information can be represented in various ways, such as Figure 8 As shown, one representation method is through the number of cell coverage rings. For example, 1 indicates that the neighboring cell is in the first ring relative to the common location point, and 2 indicates that the neighboring cell is in the second ring relative to the common location point, where the circular area represents the first location. Another representation method is as follows... Figure 9 As shown, the common location point is taken as the origin of the latitude and longitude coordinate system, and the neighboring area is represented by its position coordinates (x, y) in the coordinate system.

[0120] The relative location information mentioned above helps the satellite base station to select neighboring cells for the terminal more accurately.

[0121] In the embodiments of this application,

[0122] The step of sending a handover measurement message to the first terminal according to the ground neighbor cell list includes:

[0123] Based on the latest location information of the first terminal, a first neighboring area is selected from the neighboring areas indicated by the ground neighboring area list information. The distance between the first neighboring area and the second location is less than a third preset distance. The second location is the location indicated by the latest location information of the terminal.

[0124] Send a handover measurement message, including the first neighboring cell, to the terminal.

[0125] In some implementations of this application, the positioning information of the first terminal is the positioning information of the terminal at a first moment, and the latest positioning information is the positioning information at a second moment. Since the aforementioned ground neighbor cell list information is obtained based on the positioning information of the first terminal at the first moment, the location of the first terminal may change during the acquisition of the ground neighbor cell list information, i.e., the real-time location of the first terminal becomes the positioning information at the second moment. The satellite base station can select some suitable neighbor cells (e.g., the neighbor cell closest to the terminal's location) from the ground neighbor cell list information based on the positioning information at the second moment. Alternatively, the latest positioning information may also be the positioning information at the first moment, i.e., the location of the first terminal does not change during the acquisition of the ground neighbor cell list information. In this embodiment, based on the positioning information of the first terminal, sending a first message to the first network element includes:

[0126] Based on the location information of the first terminal, the second neighboring cell is searched in the ground neighboring cell list cached by the satellite base station, and the first terminal is within the coverage area of ​​the second neighboring cell;

[0127] If the second neighboring cell is not found, the first message is sent to the first network element.

[0128] The method in this application embodiment further includes:

[0129] If a second neighboring cell is found, a handover measurement message is sent to the first terminal based on the second neighboring cell.

[0130] In some implementations, the list of ground neighbor cells cached by the satellite base station is a list of ground neighbor cells that are used at frequencies higher than a preset frequency.

[0131] In actual communication, the satellite base station can also use caching technology to retain the list of frequently used ground neighbor cells. When a new UE needs to perform handover measurements in the coverage area of ​​the satellite base station, the historical neighbor cell list information in the cache is retrieved based on the UE's location information. When the UE's location is within the coverage area of ​​the historical neighbor cell, the satellite base station can reuse the historical neighbor cell list and configure measurement commands for the UE without having to apply for a new ground neighbor cell list from the satellite-ground cooperation unit.

[0132] like Figure 10 As shown in the embodiments of this application, a neighbor cell configuration method is also provided, applied to a first network element, the first network element including a satellite-to-ground cooperation unit or a non-terrestrial network NTN operation and maintenance center (OMC), the method including:

[0133] Step 1001: Obtain a first message sent by the satellite base station. The first message is used to request the acquisition of the ground neighbor cell list information corresponding to the first location. The distance between the location of the neighbor cell in the ground neighbor cell list information and the first location is less than a first preset distance. The first location is a location determined according to the positioning information of the first terminal.

[0134] Step 1002: Based on the first message, send a second message, the second message including the ground neighbor list information.

[0135] In some implementations, the first message mentioned above can be a ground neighbor cell list request message. The second message can be a neighbor cell configuration message.

[0136] In this embodiment, the first network element obtains a first message sent by the satellite base station, the first message being used to request the acquisition of ground neighbor cell list information corresponding to the first location; according to the first message, a second message is sent, the second message including the ground neighbor cell list information, so that the satellite base station can configure the ground neighbor cell list for the terminal based on the ground neighbor cell list information. This can significantly reduce the number of ground neighbor cells of the satellite base station and the amount of neighbor cell measurement of the terminal, thereby effectively reducing the storage space of the satellite base station for storing ground neighbor cells and the processing overhead of the satellite base station when searching for neighbor cell information.

[0137] In this embodiment of the application, the first message includes the first location.

[0138] Here, the first network element can obtain a list of neighboring cells within the range of the first terminal's location based on the first location in the first message, thereby effectively reducing the number of neighboring cells of the first terminal, and thus effectively reducing the amount of neighboring cell measurement of the first terminal and the storage space consumed by the satellite base station to store neighboring cells.

[0139] In this embodiment of the application, the first message also includes coverage area information corresponding to the first location;

[0140] The coverage area information is used to indicate the area range where the neighboring cells in the ground neighboring cell list information are located.

[0141] In this embodiment of the application, when the first network element selects a neighboring cell for the first terminal based on the first location, it can also refer to the coverage area information, which can narrow down the selection range of the neighboring cells for the first terminal.

[0142] In this embodiment of the application, the first terminal includes at least one terminal within the coverage area of ​​the satellite base station, the first location includes the location information of each terminal within the first terminal, and the first message is used to request to obtain the ground neighbor list information corresponding to the location information of each terminal within the first terminal.

[0143] Alternatively, the first terminal may include at least one group of terminals within the coverage area of ​​the satellite base station, the first location may include common location information of each group of terminals, and the first message may be used to request a list of ground neighboring cells corresponding to the common location information of each group of terminals within the first terminal, wherein each group of terminals includes at least one terminal, and the distance between terminals within the same group of terminals is less than a second preset distance, and the common location information of each group of terminals is calculated based on the location information of the same group of terminals.

[0144] In this embodiment of the application, the ground neighbor list information includes:

[0145] The ground neighbor list information includes: information on at least one neighboring cell;

[0146] Alternatively, the ground neighbor list information may include information about at least one neighboring cell, as well as the relative position information of each neighboring cell to the first location.

[0147] The first message, the second message, and the ground neighbor cell list information mentioned above have been described in the method embodiments on the satellite base station side, and will not be repeated here.

[0148] The interaction process between the satellite base station and the first network element in this application will be described below with reference to the embodiments.

[0149] Example 1:

[0150] The interaction process includes:

[0151] Step 1: The satellite base station dynamically acquires the location information (such as the latitude and longitude of the terminal) of the connected terminal in the coverage area through the location information acquisition command during the communication process, based on the communication and mobility status of the terminal in its coverage area. Based on the load and coverage area of ​​the satellite network, the service QoS requirements of the terminal, the direction of movement of the terminal, etc., it determines that the terminal needs to initiate a neighbor cell handover measurement. The target neighbor cell for handover may include terrestrial network cells.

[0152] Step 2: If it is determined that the handover neighboring cell of the terminal needs to include terrestrial network neighboring cells, the satellite base station extracts the terminal's location information and sends a terrestrial neighboring cell list request message containing the terminal's location information to the network management or satellite-ground cooperation unit (the request message may optionally include the coverage area range (e.g., in the latitude and longitude coordinate system, the distance in the X and Y directions with the terminal's location as the origin, and the shape is square or circle)) to request the terrestrial neighboring cell information around the location information;

[0153] Step 3: After receiving the neighbor cell list request message from the satellite base station, the satellite-ground cooperation unit (or NTN OMC) selects suitable ground neighbor cells from its locally stored ground neighbor cell database based on the location information piggybacked in the message, assembles the message, and sends it to the satellite base station. Upon receiving the ground neighbor cell list, the satellite base station directly assembles the received list into a UE measurement command; alternatively, it can select suitable neighbor cells (e.g., the closest neighbor cell to the terminal's location) from the neighbor cell list based on the terminal's real-time location information and assemble them into a measurement command for the UE.

[0154] Step 4: The satellite base station sends the measurement command to the UE to initiate the handover measurement process.

[0155] Example 2:

[0156] For multiple terminals within the same location range covered by a spaceborne base station, a unified location information can be used. The spaceborne base station obtains a list of neighboring ground cells around that location from the space-to-ground cooperation unit or NTN OMC, and then configures the neighboring cell list for each terminal near that location. This scheme obtains the neighboring cell list uniformly for a group of adjacent terminals, which can reduce the amount or size of messages when the spaceborne base station exchanges neighboring cell information with the NTN OMC or space-to-ground cooperation unit.

[0157] The interaction process includes:

[0158] Step 1: The satellite base station dynamically acquires the location information (such as the latitude and longitude values ​​of the terminal) of multiple terminals in the coverage area that are in a linked state during the communication process by using the location information acquisition command. Based on the satellite network load and coverage area, the terminal's service QoS requirements, the terminal's direction of movement, etc., it determines whether these terminals need to initiate neighbor cell handover measurement. The target neighbor cells for handover may include terrestrial network cells.

[0159] Step 2: The satellite-based base station groups adjacent terminals based on the received terminal location information and determines a common location information for each group. Using this common location information, it requests a list of neighboring ground cells from the satellite-ground cooperation unit for that group of terminals. Terminal grouping and determining common location information can employ clustering methods. Based on the received latitude and longitude information of each terminal, adjacent terminals are grouped together, and the coordinates of the center of each adjacent terminal in the group are calculated. If multiple groups of adjacent terminals exist, common location information is generated for each group separately.

[0160] Step 3: The satellite-borne base station sends a neighbor cell request message to the network management or satellite-ground cooperation unit. The message carries the common location information of each group of terminals and requests a list of surrounding ground neighbor cells centered on the specified common location information from the NTN OMC or satellite-ground cooperation unit.

[0161] Step 4: After receiving the neighbor cell list request message from the satellite-based base station, the satellite-ground cooperation unit (or NTN OMC) selects suitable ground neighbor cells from its locally stored ground neighbor cell database based on the location information piggybacked in the message, assembles the message, and sends it to the satellite-based base station. Upon receiving the ground neighbor cell list, the satellite-based base station, combining the location information of each group of terminals, can directly configure the common ground neighbor cell list received by the group of terminals to each terminal under that group; alternatively, it can select suitable neighbor cells (e.g., the neighbor cell closest to the terminal's location) from the group neighbor cell list based on the specific location information of the terminal and the location information of each neighbor cell in the group neighbor cell list, and assemble the measurement commands for each UE in the group. The assembled measurement commands are then sent to the terminal to initiate handover measurements.

[0162] In this embodiment, for cells where the satellite base station coverage area overlaps with or is adjacent to the terrestrial network, when a terminal needs to initiate neighbor cell handover measurement, the terminal's location information (which can be latitude and longitude information obtained via GNSS) under the satellite base station coverage area is first acquired. This location information is then sent to the NTN OMC or satellite-ground cooperation unit to obtain a list of neighbor cells within the area surrounding the terminal's location. Based on the terminal's service or mobility, the measurement command specifically configures the surrounding terrestrial neighbor cell list for the terminal requiring handover. Compared to traditional base station neighbor cell configuration and UE neighbor cell measurement configuration methods, this application dynamically and specifically acquires the terminal's neighbor cell list and configures the terminal's neighbor cell measurement message based on the terminal's location information under the satellite base station coverage beam. This significantly improves the accuracy of terminal neighbor cell measurement, reduces the terminal's processing load and the amount of message interaction between the terminal and the network, and significantly reduces the number of neighbor cell information items that the satellite base station needs to store, thus reducing the storage and processing overhead of the satellite base station.

[0163] The embodiments of this application can be used in low-Earth orbit satellite communication scenarios and 6G communication scenarios. This method can significantly reduce the neighbor cell storage of satellite base stations, reduce the neighbor cell measurement overhead of UEs, improve system performance, and has good application potential.
