Technical Field

[0002] In low-Earth orbit (LEO) satellite communications, satellite network equipment employs phased array antennas or antenna array configurations. Phased array antennas achieve dynamic coverage of a target area by electronically controlling the direction and shape of the beam, allowing terminal devices within the target area to communicate with the satellite network equipment. This technology can rapidly adjust the beam direction to adapt to the relative movement of the satellite network equipment and the terminal devices. Broadband trunking communication technology is a dedicated scheduling communication system built upon broadband wireless technology, used to uniformly schedule a group of terminal devices.

[0043] It should be noted that the beam control methods, devices, electronic devices, media, and products of this application group can be used in the field of communication technology, as well as in any field other than communication. The application fields of the beam control methods, devices, electronic devices, media, and products of this application group are not limited.

[0044] Figure 1 This is a schematic diagram illustrating an application scenario of a group beam control method provided in this application embodiment. The scenario illustrated is as follows: multiple terminal devices in a group are all located within the beam coverage area of ​​a satellite network device, and the satellite network device communicates with the multiple terminal devices.

[0045] In practical applications, terminal devices must be within the beam coverage area to communicate with satellite network devices. Both satellite network devices and terminal devices can be mobile. The satellite network devices adjust the beam coverage area through beam control to ensure that multiple terminal devices in the group are always within the beam coverage area, thus ensuring reliable communication between the satellite network devices and terminal devices.

[0046] For example, group communication is a technology in which multiple terminal devices exchange information by sharing communication resources. In group communication, messages sent by satellite network devices can be received by multiple terminal devices, thereby reducing signaling overhead. However, the locations of the multiple terminal devices in the group are different, so group communication needs to consider whether all the communication devices in the group are within the beam coverage area to ensure the reliability of group communication.

[0047] For example, beam control refers to achieving coverage of a ground area by adjusting parameters such as the direction, width, or power of a beam. For instance, when some terminal devices move outside the beam's coverage area, satellite network equipment can adjust the beam's power to expand the coverage area so that the expanded coverage includes the terminal devices, thus maintaining their communication. Therefore, beam control needs to be based on the location of the terminal devices.

[0048] For example, a beam is a directional energy distribution formed when electromagnetic waves propagate in space. In communication, a beam concentrates signal energy in a specific direction so that a terminal device can receive the signal corresponding to the beam.

[0049] In related technologies, terminal devices report their current location to satellite network equipment in real time, and the satellite network equipment determines whether to perform beam control based on the reported location. Real-time location reporting frequently consumes uplink resources, leading to high uplink resource consumption.

[0050] The method for beam control of a group provided in this application is intended to solve the above-mentioned technical problems of the prior art.

[0051] The technical solution of this application and how the technical solution of this application solves the above-mentioned technical problems are described in detail below with specific embodiments. These specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments. The embodiments of this application will now be described with reference to the accompanying drawings.

[0052] Figure 2 This application provides a schematic flowchart of a group beam control method, which includes the following steps:

[0053] S201. Receive a group paging message sent by the current satellite network device. The group paging message includes the dynamic coverage range of the beam of the current satellite network device.

[0054] As an example, the executing entity of this embodiment can be any one of the multiple terminal devices in the group.

[0055] For example, the current satellite network device is the satellite network device currently accessing the group.

[0056] For example, group paging is a key signaling mechanism in Broadband Trunking Communication (B-TrunC) systems for scheduling group communications. Currently, satellite network equipment sends group paging messages to terminal devices to instruct them to perform specified operations.

[0057] For example, a terminal device within the dynamic coverage area can receive signals from the current satellite network device, thereby communicating with the current satellite network device.

[0058] Optionally, multiple terminal devices in the group may be located on the ground or in the air.

[0059] Optionally, the group paging message may include, but is not limited to, at least one of the following: current satellite network device identifier, synchronization time, ephemeris information, group identifier, group service priority, or time and frequency resource information of the group service.

[0060] S202. Based on the mobile information and dynamic coverage of multiple terminal devices in the group, determine multiple expected locations of multiple terminal devices.

[0061] For example, mobility information includes, but is not limited to, the speed or direction of movement of the terminal device.

[0062] For example, the expected location is the predicted location of the terminal device at a future time based on dynamic coverage.

[0063] With scenario examples, the expected location can be used to determine in advance whether the terminal device will move outside the dynamic coverage area, thereby instructing the satellite network equipment to perform beam control in advance to improve the accuracy of beam control.

[0064] S203. Determine the out-of-range location from multiple expected locations that is outside the dynamic coverage range, and send the out-of-range location to the current satellite network equipment so that the current satellite network equipment can perform beam control and adjust the dynamic coverage range based on the out-of-range location.

[0065] For example, by comparing multiple expected locations with dynamic coverage areas, out-of-range locations among the multiple expected locations can be identified. Terminal devices at out-of-range locations cannot receive signals from satellite network devices.

[0066] For example, the current satellite network equipment adjusts the dynamic coverage range so that the adjusted dynamic coverage range can cover multiple terminal devices, and enables the multiple terminal devices to perform a new round of location prediction and reporting based on the adjusted dynamic coverage range, so as to enable the terminal devices to communicate with the current satellite network equipment at all times.

[0067] With the help of scenario examples, the movement of a terminal device can lead to two scenarios: the terminal device's new location is within the dynamic coverage area, or it is outside the dynamic coverage area. If the terminal device's new location is within the dynamic coverage area, it can still receive signals from the current satellite network device and communicate. Even if it reports its location to the current satellite network device, the current device does not need to perform beam control, thus wasting uplink resources. If the terminal device's new location is outside the dynamic coverage area, it cannot communicate normally with the current satellite network device after moving. In this case, beam control is required. Reporting its location instructs the current satellite network device to perform beam control to maintain communication between the terminal device and the current satellite network device. Therefore, reporting its location is a necessary action, and the use of uplink resources is considered effective utilization.

[0068] Optionally, the terminal device may transmit the corresponding expected time at the same time as transmitting the location outside the range. The expected time is the time when the terminal device is expected to be located outside the range. The expected time is used to indicate the time when the current satellite network device should perform beam control, so that the beam control is matched with the movement of the terminal device, thereby performing beam control accurately.

[0069] The beam control method for a group provided in this application receives a group paging message sent by a current satellite network device. The group paging message includes the dynamic coverage range of the current satellite network device's beam. Based on the movement information and dynamic coverage range of multiple terminal devices in the group, multiple expected locations of the multiple terminal devices are determined. From the multiple expected locations, a location outside the dynamic coverage range is determined and sent to the current satellite network device, so that the current satellite network device can perform beam control and adjust the dynamic coverage range based on the location outside the dynamic coverage range. In this scheme, the terminal devices in the group only report the specified location to the satellite network device based on the group paging message sent by the satellite network device, thereby reducing the number of reporting times and saving communication resources.

[0070] Based on any of the above embodiments, the following, in conjunction with Figure 3 The detailed process of beam control for the group is explained.

[0071] Figure 3 This is a flowchart illustrating a group beam control method provided in an embodiment of this application. Figure 3 As shown, the method includes:

[0072] S301. Receive a group paging message sent by the current satellite network device. The group paging message includes the dynamic coverage range of the beam of the current satellite network device.

[0073] One feasible implementation method for beam control of a group may further include: beam alignment based on current beam information to enable multiple terminal devices to communicate with the current satellite network equipment.

[0074] The group paging message also includes the current beam information.

[0075] For example, current beam information includes, but is not limited to, beamforming vectors, beam direction angles, or frequency bands of the current satellite network equipment.

[0076] For example, the terminal device adjusts the beam direction and parameters of its own antenna array according to the current beam information to align it with the beam of the current satellite network device, thereby reducing signal interference and improving communication quality.

[0077] In this feasible implementation, sending the current beam information via group paging messages can improve message utilization and save communication resources compared to sending the current beam information individually.

[0078] One feasible implementation may include, before receiving a group paging message sent by the current satellite network equipment, determining multiple initial positions and multiple initial velocities of multiple terminal devices; and sending the multiple initial positions and multiple initial velocities to the control center so that the control center can determine the dynamic coverage area based on the multiple initial positions and multiple initial velocities.

[0079] For example, the control center determines the dynamic coverage area based on the initial position and initial speed of the terminal device.

[0080] Optionally, after determining the dynamic coverage area, the control center sends the dynamic coverage area to the current satellite network equipment, so that the satellite network equipment can send the dynamic coverage area to the terminal equipment.

[0081] Optionally, dynamic coverage range includes margin control. For example, the control center determines the movement range of the terminal device over a certain period of time based on its initial position and initial speed. Then, a margin is added to this movement range to obtain a larger range as the dynamic coverage range. In actual use, the movement of the terminal device is uncertain. Margin control can effectively address the movement of the terminal device, reducing the number of beam control operations and thus reducing the number of times the terminal device reports its position.

[0082] Optionally, the dynamic coverage area can be defined as a circle or approximately a circle, as shown in the reference. Figure 1 The circular or near-circular dynamic coverage area conforms to the symmetrical design of the antenna beams of current satellite network equipment.

[0083] Optionally, the control center may include a service control module (TCF), which calculates the dynamic coverage range based on multiple initial positions, multiple initial speeds, and margin.

[0084] Below, in conjunction with Figure 4 The method for determining dynamic coverage is explained.

[0085] Figure 4 This is a schematic diagram illustrating the determination of dynamic coverage area as provided in an embodiment of this application. Figure 4 As shown, the terminal device sends its initial position and initial velocity to the control center. The control center determines the dynamic coverage area based on the initial position and initial velocity, sends the dynamic coverage area to the current satellite network device, and the current satellite network device sends the dynamic coverage area to the terminal device.

[0086] For example, satellite network equipment has limited computing power. By using the computing power of satellite network equipment for communication, and by determining the dynamic coverage area through the control center, the computing pressure on satellite network equipment can be reduced.

[0087] In this feasible implementation, the dynamic coverage area is determined by the control center, which can alleviate the computing pressure on satellite network equipment, allowing the satellite network equipment to focus on communication and thus improve the quality of communication.

[0088] One feasible implementation method is to send multiple initial positions and multiple initial velocities to the control center by: receiving preset conditions sent by the control center, the preset conditions including a transmission period and / or a position change threshold; and when the preset conditions are met, sending multiple initial positions and multiple initial velocities to the control center.

[0089] For example, preset conditions are used to control the frequency at which the terminal device sends initial position and initial speed, in order to control the consumption of communication resources.

[0090] As an example, the default condition is a transmission cycle, where the terminal device sends its initial position and initial speed to the control center once every transmission cycle.

[0091] As another example, the preset condition is a position change threshold. When the displacement of the terminal device is greater than or equal to the position change threshold, it means that the terminal device has moved a long distance. At this time, it is necessary to redetermine the dynamic coverage range so that the new dynamic coverage range covers the terminal device.

[0092] As another example, the preset conditions are the transmission period and the position change threshold. When either condition is met, the initial position and initial velocity are transmitted once.

[0093] In this feasible implementation, the frequency at which the terminal device sends the initial position and initial speed is controlled by preset conditions. Compared with real-time transmission, the transmission frequency can be reduced, thereby saving communication resources.

[0094] S302. Determine the center coordinates of the dynamic coverage area.

[0095] For example, taking a dynamic coverage area that is circular or approximately circular as an example, the center coordinates are the coordinates of the center of the dynamic coverage area. The center coordinates can be used as an accurate reference to accurately determine whether the location of the terminal device is outside the coverage area.

[0096] S303. Determine the current speed of the terminal device based on the mobile information.

[0097] For example, the current speed reflects the current direction and rate of movement of the terminal device, and is used to predict the future position of the terminal device.

[0098] Optionally, the terminal device may record its speed during movement using its Global Positioning System (GPS) or an accelerometer.

[0099] S304. Based on the mobile information and center coordinates, determine the current coordinates of the terminal device relative to the center coordinates.

[0100] One feasible implementation is that the group paging message also includes a speed threshold; the current coordinates can be determined by the following methods: determining whether the current speed is greater than or equal to the speed threshold; if so, then determining the current coordinates of the terminal device relative to the center coordinates based on the mobility information and the center coordinates.

[0101] For example, the speed threshold is used as a criterion for determining the current coordinates. The current coordinates are determined only when the current speed is greater than or equal to the speed threshold, so as to reduce the number of times the current coordinates are determined.

[0102] With the example of the scenario, if the current speed is less than the speed threshold, it means that the terminal device is only making a small movement. Since the dynamic coverage range includes a margin, the small movement will not cause the terminal device to exceed the dynamic coverage range. Therefore, it is not necessary to determine the current coordinates and report the location.

[0103] In this feasible implementation, the frequency of determining the current coordinates by controlling the speed threshold can reduce the number of times the position is reported, thereby saving communication resources.

[0104] S305. Based on the current coordinates, center coordinates, and current speed, perform segmented calculations according to time intervals to obtain multiple expected positions of the terminal device at multiple expected times, with a time interval between two adjacent expected times.

[0105] For example, taking a dynamically covered area that is circular or approximately circular, with the center coordinates being the coordinates of the center of the circle, the X-axis and Y-axis coordinates of multiple expected locations can be calculated using the following formula:

[0106]

[0107]

[0108] in, The expected position is the X-axis coordinate relative to the center coordinate. This represents the component of the current velocity on the X-axis. For time intervals, This is the X-axis coordinate of the current coordinate relative to the center coordinate. The expected position is the Y-coordinate relative to the center coordinate. This represents the component of the current velocity on the Y-axis. This is the Y-axis coordinate of the current coordinate relative to the center coordinate.

[0109] Furthermore, the radius of the dynamic coverage area is The area is ,according to Is the result greater than This is to determine whether the prefetched location is outside the dynamic coverage area.

[0110] It should be noted that the calculation method for the dynamic coverage of other shapes is the same.

[0111] Below, in conjunction with Figure 5 Explain the expected location.

[0112] Figure 5 This is a schematic diagram illustrating the intended location provided in the embodiments of this application. For example... Figure 5 As shown, time A is the current time. By segmenting the calculations, the expected locations of the terminal device at times B and C can be obtained. It can be seen that the terminal device is predicted to be outside the dynamic coverage area at time C. Effective reporting can be achieved by reporting the location outside the coverage area at time C.

[0113] To illustrate with a scenario example, segmented computation involves calculating the coordinates of a predicted location at regular time intervals. Each coordinate represents the predicted position of the terminal device at the corresponding expected time. Segmented computation reduces the amount of computation required.

[0114] Based on the above implementation method, the number of calculations is reduced by segmenting the calculations, thereby saving computing resources.

[0115] S306. Determine the out-of-range location from multiple expected locations that is outside the dynamic coverage range, and send the out-of-range location to the current satellite network equipment so that the current satellite network equipment can perform beam control and adjust the dynamic coverage range based on the out-of-range location.

[0116] Below, in conjunction with Figure 6 The beam control is explained.

[0117] Figure 6 This is a schematic diagram of beam control provided in an embodiment of this application. Figure 6 As shown, the terminal device sends its predicted out-of-range location to the current satellite network device, enabling the current satellite network device to perform beam control based on this out-of-range location. The current satellite network device then sends the adjusted dynamic coverage area and beam information to the terminal device, enabling the terminal device to perform a new round of location prediction and reporting based on the adjusted dynamic coverage area.

[0118] One feasible implementation method for beam control of a group may further include: receiving a handover instruction sent by an updated satellite network device, wherein the updated satellite network device is used to replace the current satellite network device; determining the updated beam information of the updated satellite network device according to the handover instruction; and performing beam alignment according to the updated beam information to enable multiple terminal devices to communicate with the updated satellite network device.

[0119] With the example scenario, the updated satellite network device is used to replace the current satellite network device. As the current satellite network device moves, its beam coverage may shift significantly, leaving the group's service cell range. Terminal devices in the group will then be unable to access the current satellite network device. In this case, it is necessary to switch the satellite network device that the terminal devices are connected to; the switched satellite network device is the updated satellite network device.

[0120] For example, after the current satellite network device moves out of its serving cell, it sends location update control information to the updating satellite network device. This enables the updating satellite network device to obtain the dynamic coverage area of ​​the group, calculate beam parameters based on the center location of the dynamic coverage area, and generate beam information. Subsequently, the updating satellite network device dynamically performs beam control based on the reported location information of the terminal devices in the group.
