Description

Technical Field

[0001] This invention relates to the field of communication technology, and more specifically, to a method, apparatus, and device for configuring mobility measurement of NTN network satellite base stations. Background Technology

[0002] With the rapid development of satellite communication technology, satellite base stations have demonstrated significant advantages in terms of wide coverage and seamless connectivity, becoming an important means to improve network service quality in remote areas and mobile regions. By configuring measurement functions, satellite base stations periodically collect key parameters such as signal quality, location, and handover requirements of user terminals within their coverage area, ensuring the stability of communication links and the timeliness of handover, thereby guaranteeing users' communication experience and network performance.

[0003] However, existing satellite base stations typically perform uniform configuration measurements on all user terminals within their coverage area, indiscriminately collecting terminal status information. While this approach ensures comprehensiveness and accuracy in handover, it results in a large number of user terminals in central areas being continuously subjected to high-frequency measurements, leading to a significant increase in power consumption, shortened battery life, and consequently impacting user experience. Furthermore, for terminals located close to the center of the base station and with stable signals, frequent measurements and handover decisions are redundant, resulting in low resource utilization efficiency. Summary of the Invention

[0004] The problem addressed by this invention is how to achieve a balance between edge user handover performance and central user power consumption.

[0005] To address the aforementioned problems, this invention provides a method, apparatus, and device for configuring mobility measurement of NTN network satellite base stations.

[0006] In a first aspect, the present invention provides a method for configuring mobility measurement of an NTN network satellite base station, comprising: Based on satellite operational information, the coverage area of ​​the satellite-borne base station is divided into a monitoring area and a configuration area. The operational information includes the direction of operation and the trajectory of operation. The satellite-borne base station is set on the satellite. When the obtained location information of the terminal shows that the terminal is within the monitoring area, the location of the terminal is monitored and the location information is updated. When the location information indicates that the terminal is within the configured area, a mobility configuration measurement is performed on the terminal.

[0007] Optionally, the satellite-based operational information divides the coverage area of ​​the satellite-borne base station to obtain the monitoring area and configuration area, including: The coverage area is divided according to the running direction and the preset distance to obtain a first area and a second area; Based on the operating trajectory, the first region, and the second region, the monitoring area and the configuration area of ​​the satellite base station at different times are obtained.

[0008] Optionally, dividing the coverage area according to the running direction and a preset distance to obtain a first area and a second area includes: The coverage area is divided into cells to obtain multiple cells; The target edge region of the coverage area is divided into a second region, and the remaining cells in the coverage area excluding the target edge region are divided into a first region. The target edge region is the edge region at each edge of the coverage area except for the front edge. The front edge is the edge in the coverage area that runs in the same direction as the running direction. The edge region is composed of multiple cells distributed along the corresponding edge, and the distance between the cell in the edge region that is furthest from the corresponding edge and the corresponding edge is the preset distance.

[0009] Optionally, obtaining the monitoring area and the configuration area of ​​the satellite-borne base station operating at different times based on the operating trajectory, the first area, and the second area includes: Based on the described trajectory, the coverage area of ​​the satellite-borne base station at each moment is obtained; The first region and the second region within the coverage area at each time moment are determined to obtain the monitoring area and the configuration area of ​​the satellite-borne base station at different times.

[0010] Optionally, the mobility configuration measurement of the terminal includes: The configuration measurement events for performing mobility configuration measurements include at least one of the following: A2 event, A4 event, and D2 event.

[0011] Optionally, dividing the coverage area according to the running direction and a preset distance to obtain a first area and a second area includes: Extending a first distance from the center of the covered area to the edge of the covered area, a first area to be processed and a second area to be processed are obtained, wherein the first distance is obtained based on the difference between the radius of the covered area and the preset distance; The two regions to be processed corresponding to the front edge are included in the first region to be processed, resulting in the first region and the second region. The front edge is the edge of the coverage area obtained according to the running direction and the preset division angle.

[0012] Optionally, the NTN network satellite base station mobility measurement configuration method is characterized by further comprising: Obtain the central axis of the coverage area that is parallel to the direction of operation; With the central axis as the center, the preset division angle is deflected to both sides of the central axis to obtain a fan-shaped region; The front edge is obtained by acquiring the edge of the fan-shaped region.

[0013] Secondly, the present invention provides an NTN network spaceborne base station mobility measurement configuration device, comprising: The segmentation module is used to segment the coverage area of ​​the satellite-borne base station based on the satellite's operational information to obtain a monitoring area and a configuration area. The operational information includes the direction of operation and the trajectory of operation. The satellite-borne base station is set on the satellite. The monitoring module is used to monitor the location of the terminal and update the location information when the acquired location information shows that the terminal is within the monitoring area; The configuration module is used to perform mobility configuration measurement on the terminal when the location information indicates that the terminal is within the configuration area.

[0014] Thirdly, the present invention provides an electronic device, including a memory and a processor; The memory is used to store computer programs; The processor is configured to, when executing the computer program, implement the NTN network satellite base station mobility measurement configuration method as described in the first aspect.

[0015] Fourthly, the present invention provides a computer-readable storage medium storing a computer program that, when executed by a processor, implements the NTN network satellite base station mobility measurement configuration method as described in the first aspect.

[0016] The beneficial effects of the NTN network satellite-borne base station mobility measurement and configuration method, apparatus, and equipment of the present invention are as follows: The coverage area of ​​the satellite-borne base station is divided according to the orbital direction and trajectory of the satellite in the NTN network, resulting in monitoring areas with high signal strength and quality that meet the terminal's communication needs, and configuration areas with low signal strength and poor quality that do not meet the terminal's communication needs. This achieves accurate area division, for example, when low-orbit satellites are moving, to determine the terminal's location in real time. When the acquired terminal's location information is within the monitoring area, it indicates that the terminal has no handover requirement, and the satellite-borne base station does not perform mobility management-related measurement and configuration on the terminal. Instead, it monitors the terminal's location and updates the location information, reducing terminal power consumption. When the location information is within the configuration area, it indicates that the terminal has a handover requirement. Mobility configuration measurement is performed on the terminal, and then the terminal initiates measurement of the serving cell or neighboring cells according to the satellite-borne base station configuration. This enables timely and accurate identification of the terminal's handover requirement, avoids measurement and configuration for users in the central area, effectively reduces the energy consumption of terminals in the central area, improves user experience, and also reduces the signaling load for terminal measurement and configuration. This embodiment divides the base station coverage area according to the satellite base station operation information and uses the terminal location information to dynamically match the measurement strategy, solving the inefficiency problem of "one-size-fits-all" configuration within the satellite coverage area and achieving the optimal balance between edge user handover performance and central user power consumption.

[0024] In related technologies, mobility measurement configuration when a terminal is connected to a satellite-based base station employs a unified measurement configuration strategy for all terminals within the coverage area of ​​the satellite-based base station. That is, all terminals within the satellite's coverage area are configured according to the aforementioned configuration process. For example, in situations such as... Figure 2In the example diagram of satellite base station coverage shown, all terminals in coverage area 1 of satellite 1 undergo mobility configuration measurements. However, when a terminal is in the edge of the coverage area, since the current coverage area of ​​the local satellite will be covered by a neighboring satellite, the terminal needs to switch to the neighboring satellite, requiring mobility management-related measurement configurations. When the terminal is in the central area of ​​the satellite base station coverage, the signal strength and quality are high, which can meet the terminal's communication needs, such as mobile internet access and voice calls, which can be carried out stably. Moreover, the interference from other neighboring cells is relatively weak, and there is no need to switch to other cells to improve the signal. Terminals in the central area will also start measurements after receiving network configuration measurements even without switching needs, resulting in wasted terminal power consumption and reduced user experience.

[0025] To address the problems existing in the aforementioned related technologies, this embodiment provides a method, apparatus, and equipment for configuring mobility measurement of NTN network satellite base stations.

[0026] like Figure 1 As shown in the figure, an embodiment of the present invention provides a method for configuring mobility measurement of an NTN network satellite base station, including: Based on satellite operational information, the coverage area of ​​the satellite-borne base station is divided into a monitoring area and a configuration area. The operational information includes the direction of operation and the trajectory of operation. The satellite-borne base station is set on the satellite.

[0027] Specifically, the coverage area of ​​the satellite-borne base station is divided based on satellite operational information. This operational information includes the direction of operation (e.g., due north, 30° east of north) and the trajectory (recorded as a series of geographic coordinates). For example, a certain angular range directly in front of the base station's direction of operation—e.g., a fan-shaped area formed by 30° angles to the left and right of the base station's direction of operation as the central axis—and the coverage area within a certain distance (e.g., 50km) from the base station's center are designated as monitoring areas. These monitoring areas focus on signal strength, interference, and the number of connected terminals to promptly assess the communication status of the area to be covered by the base station. The remaining coverage area of ​​the base station, excluding the monitoring areas, is designated as configuration areas. These configuration areas primarily adjust resource allocation, such as power adjustment and channel allocation, based on information from the monitoring areas and the base station's own operational status. In NTN (Non-Terrestrial Network), for example, low-Earth orbit satellites move at high speeds according to preset trajectories. Therefore, the pre-defined monitoring and configuration areas should be matched and divided according to the acquired trajectories to obtain the monitoring and configuration areas of the satellite base station at any time on the trajectories, so as to enable real-time monitoring, measurement, and configuration judgment of the terminal location.

[0028] When the acquired terminal location information shows that the terminal is within the monitoring area, the location of the terminal is monitored and the location information is updated.

[0029] Specifically, when the obtained location information of the terminal is within the monitoring area, it indicates that the terminal has no handover requirement. The satellite base station does not perform mobility management related measurement configurations for the terminal. At this time, the satellite moves according to its trajectory, and the satellite base station updates the coverage area where the terminal is located periodically based on the monitoring area and the configuration area.

[0030] When the location information indicates that the terminal is within the configured area, a mobility configuration measurement is performed on the terminal.

[0031] Specifically, when the terminal's location information is within the configured area, it indicates that the terminal has a handover requirement. The satellite base station performs mobility management-related measurement configurations for the terminal in the RRC (Radio Resource Control) reconfiguration process, such as serving cell handover measurement. The configured measurement events can be A2 / A4 / D2, etc. Then, the terminal initiates measurements of the serving cell or neighboring cells according to the satellite base station configuration.

[0032] The terminal measurement configuration process of this invention embodiment is as follows: Figure 3 As shown: 1. The satellite-borne base station divides its coverage area based on its operational information to obtain a monitoring area and a configuration area; 2. The terminal accesses the satellite-based base station, which performs initial mobility management-related measurement and reporting configurations for the terminal through the radio resource control reconfiguration process. 3. Perform NAS (Non-Access Stratum Authentication) authentication and security-related processes, during which the terminal's identifier (UE ID) and access layer related security context (AS SMC) are obtained, and the terminal's capabilities are acquired. 4. The terminal reports coarse location information (CoarseLocationInfo) through User Assistance Information (UAI). 5. The satellite-based base station determines whether the terminal is located in the monitoring area or the configuration area based on the rough location information reported by the terminal, and adopts different mobility measurement configuration strategies for terminals in different areas: Scenario 1: When the terminal is within the monitoring area: 6a. When the terminal is in the monitoring area and there is no handover requirement, the satellite base station will not perform mobility management related measurement configurations on the terminal. 7a. The satellite moves according to its orbital trajectory, and the onboard base station updates the terminal's location periodically based on the location reported by the terminal. 8a. When the satellite base station determines that the terminal has moved out of the monitoring area and into the configuration area, it initiates the RRC reconfiguration process to configure the mobility-related measurement configuration for the terminal. The configured measurement events can be A2 / A4 / D2 and other events. 9a. The terminal initiates measurement of the serving cell / neighboring cell according to the configuration of the satellite base station.

[0033] Scenario 2: When the terminal is in the configuration area: 6b. When the terminal is in the configuration area and has a handover requirement, the satellite base station performs mobility management related measurement configurations on the terminal during the RRC reconfiguration process. The configured measurement events can be A2 / A4 / D2, etc. 7b. The terminal initiates measurements of the serving cell / neighboring cell according to the configuration of the satellite base station.

[0034] In this embodiment, the coverage area of ​​the satellite-borne base station is divided according to the satellite's direction and trajectory under the NTN network. This results in monitoring areas with high signal strength and quality that meet the terminal's communication needs, and configuration areas with low signal strength and poor quality that do not meet the terminal's communication needs. This ensures accurate area division, for example, when low-orbit satellites are moving, allowing for real-time determination of the terminal's location. When the acquired terminal's location information is within the monitoring area, it indicates that the terminal has no handover requirement. The satellite-borne base station does not perform mobility management-related measurement configurations on the terminal, but monitors the terminal's location and updates the location information, reducing terminal power consumption. When the location information is within the configuration area, it indicates that the terminal has a handover requirement. Mobility configuration measurements are performed on the terminal, and then the terminal initiates measurements of the serving cell or neighboring cells according to the satellite-borne base station configuration. This enables timely and accurate identification of the terminal's handover requirement, avoids measurement configurations for users in the central area, effectively reduces the energy consumption of terminals in the central area, improves user experience, and also reduces the signaling load of measurement configurations for the terminal. This embodiment divides the base station coverage area according to the satellite base station operation information and uses the terminal location information to dynamically match the measurement strategy, solving the inefficiency problem of "one-size-fits-all" configuration within the satellite coverage area and achieving the optimal balance between edge user handover performance and central user power consumption.

[0035] Optionally, the satellite-based operational information divides the coverage area of ​​the satellite-borne base station to obtain the monitoring area and configuration area, including: The coverage area is divided according to the running direction and the preset distance to obtain a first area and a second area.

[0036] Based on the operating trajectory, the first region, and the second region, the monitoring area and the configuration area of ​​the satellite base station at different times are obtained.

[0037] Specifically, the coverage area is initially divided based on the direction of operation and a preset distance. For example, the edge of the coverage area corresponding to the fan-shaped area formed by the base station's direction of operation as the central axis and the angles to the left and right of each other at 30° is not divided. The area extending a preset distance (e.g., 10km) from the edge of the other coverage areas is divided into the second area, and the remaining coverage areas are divided into the first area. The first and second areas are matched according to the coverage area of ​​the satellite during its operation trajectory to obtain the monitoring area and configuration area at different times during satellite operation. This ensures that the onboard base station can accurately determine the configuration measurement based on the terminal location, configuration area, and monitoring area during satellite operation.

[0038] Optionally, dividing the coverage area according to the running direction to obtain a first area and a second area includes: The coverage area is divided into cells to obtain multiple cells; The target edge region of the coverage area is divided into a second region, and the remaining cells in the coverage area excluding the target edge region are divided into a first region. The target edge region is the edge region at each edge of the coverage area except for the front edge. The front edge is the edge in the coverage area that runs in the same direction as the running direction. The edge region is composed of multiple cells distributed along the corresponding edge, and the distance between the cell in the edge region that is furthest from the corresponding edge and the corresponding edge is the preset distance.

[0039] Specifically, the coverage area can be divided into cells according to preset side lengths, resulting in, for example: Figure 4 The coverage area shown is defined as the front edge along the side facing the satellite's direction of travel. Besides the front edge, the coverage area also includes three end edges. The ratio of a preset distance to the side length of a cell is obtained to determine the preset number of cells. The preset number of cells closest to the three end edges are designated as the second region corresponding to the configured area, and the remaining cells are designated as the first region corresponding to the monitoring area. Figure 4 As shown, the preset distance range near the three edges is divided into a second region corresponding to the configuration area, as follows: Figure 4 The dark shaded area in the image is used to divide other areas into the first region corresponding to the monitoring area, as shown in the light-colored area in the image. Correspondingly, different neighboring stars can also be divided into regions using this method.

[0040] It's important to note that during satellite coverage, areas at the forefront of the operational direction, where satellites are about to reach but haven't yet established stable coverage, are not significantly affected by the current phase of defining configuration zones. This is because configuration zone allocation is generally based on areas with stable coverage, allowing for targeted resource allocation and management, while the front-end edge areas haven't yet achieved stable coverage. Furthermore, if configuration zones were also defined at the front-end edge, two connected configuration zones would be created at the junction of two satellites. If a terminal is located within this configuration zone, it will repeatedly switch between the two satellites. Therefore, when defining the second zone, excluding the front-end edge further ensures terminal switching stability.

[0041] Optionally, obtaining the monitoring area and the configuration area of ​​the satellite-borne base station operating at different times based on the operating trajectory, the first area, and the second area includes: Based on the described trajectory, the coverage area of ​​the satellite-borne base station at each moment is obtained; The first region and the second region within the coverage area at each time moment are determined to obtain the monitoring area and the configuration area of ​​the satellite-borne base station at different times.

[0042] Specifically, based on the satellite's trajectory, the coverage area of ​​the base station at each moment is obtained, and the first and second areas are matched to the coverage area. The coverage area is then updated to obtain the monitoring area and configuration area at each moment.

[0043] Optionally, the mobility configuration measurement of the terminal includes: The configuration measurement events for performing mobility configuration measurements include at least one of the following: A2 event, A4 event, and D2 event.

[0044] Specifically, the selection of measurement events can be configured according to different application scenarios.

[0045] Optionally, dividing the coverage area according to the running direction to obtain a first area and a second area includes: Extending a first distance from the center of the covered area to the edge of the covered area, a first area to be processed and a second area to be processed are obtained, wherein the first distance is obtained based on the difference between the radius of the covered area and the preset distance; The two regions to be processed corresponding to the front edge are included in the first region to be processed, resulting in the first region and the second region. The front edge is the edge of the coverage area obtained according to the running direction and the preset division angle.

[0046] Specifically, the division method based on the first distance is applicable to divisions where the coverage area is elliptical or circular. The first distance is obtained by subtracting the radius of the coverage area from a preset distance. If the coverage area is elliptical, the first distance is calculated using the minor semi-axis as the radius. Extending the first distance from the center of the coverage area towards its edge according to its shape, the area near the center is divided into the first region to be processed, corresponding to the monitoring area, and the area near the edge is divided into the second region to be processed, corresponding to the configuration area. The front edge is obtained based on the operating direction and a preset division angle. For example, using the base station's operating direction as the central axis, the edge of the coverage area corresponding to the fan-shaped area formed by preset division angles (such as a 30° angle) on the left and right is taken as the front edge. The second region to be processed corresponding to the front edge is incorporated into the first region. The second region to be processed, after delineating the second region to be processed corresponding to the front edge, is taken as the first region. The remaining second region to be processed after delineating the second region to be processed is taken as the second region.

[0047] Optionally, it also includes: Obtain the central axis of the coverage area that is parallel to the direction of operation; With the central axis as the center, the preset division angle is deflected to both sides of the central axis to obtain a fan-shaped region; The front edge is obtained by acquiring the edge of the fan-shaped region.

[0048] Specifically, taking an elliptical coverage area as an example, a central axis parallel to the direction of operation is constructed, starting from the center of the coverage area. A fan-shaped area is obtained by rotating the center axis to both sides of the central axis by a preset angle. For example, a fan-shaped area is formed by using the direction of operation of the base station as the central axis and the preset angles (such as a 30° angle) on the left and right. The edge of the coverage area corresponding to this fan-shaped area is the front edge.

[0049] like Figure 7 As shown, a first distance h is extended from the center of the coverage area, i.e., center point a, to the edge of the coverage area to obtain a first region to be processed and a second region to be processed; the front edge b is determined according to the central axis l deflected by a preset angle of 30°, and the second region to be processed corresponding to the front edge is included in the first region to be processed, resulting in the following... Figure 7 The first region shown in the blank area and as shown in the blank area Figure 7 The second region is shown in the medium gray area.

[0050] like Figure 5 As shown in the figure, an NTN network spaceborne base station mobility measurement configuration device 500 provided in this embodiment of the invention includes: The segmentation module 510 is used to segment the coverage area of ​​the satellite-borne base station based on the satellite's operational information to obtain a monitoring area and a configuration area. The operational information includes the direction of operation and the trajectory of operation. The satellite-borne base station is set on the satellite. The monitoring module 520 is used to monitor the location of the terminal and update the location information when the acquired location information of the terminal shows that the terminal is in the monitoring area; The configuration module 530 is used to perform mobility configuration measurement on the terminal when the location information shows that the terminal is in the configuration area.

[0051] Optionally, the partitioning module 510 is further configured to: The coverage area is divided according to the running direction and the preset distance to obtain a first area and a second area; Based on the operating trajectory, the first region, and the second region, the monitoring area and the configuration area of ​​the satellite base station at different times are obtained.

[0052] Optionally, the partitioning module 510 is further configured to: The coverage area is divided into cells to obtain multiple cells; The target edge region of the coverage area is divided into a second region, and the remaining cells in the coverage area excluding the target edge region are divided into a first region. The target edge region is the edge region at each edge of the coverage area except for the front edge. The front edge is the edge in the coverage area that runs in the same direction as the running direction. The edge region is composed of multiple cells distributed along the corresponding edge, and the distance between the cell in the edge region that is furthest from the corresponding edge and the corresponding edge is the preset distance.

[0053] Optionally, the partitioning module 510 is further configured to: Based on the described trajectory, the coverage area of ​​the satellite-borne base station at each moment is obtained; The first region and the second region within the coverage area at each time moment are determined to obtain the monitoring area and the configuration area of ​​the satellite-borne base station at different times.

[0054] Optionally, the detection module 520 and the configuration module 530 are further configured to: The configuration measurement events for performing mobility configuration measurements include at least one of the following: A2 event, A4 event, and D2 event.

[0055] Optionally, the partitioning module 510 is further configured to: Extending a first distance from the center of the covered area to the edge of the covered area, a first area to be processed and a second area to be processed are obtained, wherein the first distance is obtained based on the difference between the radius of the covered area and the preset distance; The two regions to be processed corresponding to the front edge are included in the first region to be processed, resulting in the first region and the second region. The front edge is the edge of the coverage area obtained according to the running direction and the preset division angle.

[0056] Optionally, the partitioning module 510 is further configured to: Obtain the central axis of the coverage area that is parallel to the direction of operation; With the central axis as the center, the preset division angle is deflected to both sides of the central axis to obtain a fan-shaped region; The front edge is obtained by acquiring the edge of the fan-shaped region.
