Description

Technical Field

[0001] The present application relates to the technical field of satellite communication, and in particular, to a low-earth and high-earth orbit satellite integrated communication method, apparatus, electronic device, and storage medium. Background Art

[0002] The communication satellites used by conventional terminal communication devices such as mobile phones and computers are generally high-earth orbit satellites. A small number of high-earth orbit satellites can cover the globe, but high-earth orbit satellite communication has a high latency, and high-earth orbit satellites are usually narrowband satellites, so they can only support short messages and voice calls. Therefore, in order to reduce communication latency and meet the communication requirements of more communication methods, low-earth orbit satellites can be used to provide satellite communication services for terminal communication devices in a certain regional area. To achieve coverage of a certain regional area, multiple low-earth orbit satellites often need to switch between each other and alternately transmit signals.

[0003] However, since the coverage range of a single low-earth orbit satellite is limited and the communication time between it and ground terminal communication devices is short, basically within a few minutes, during the communication handover process between low-earth orbit satellites, there may be a situation where the target low-earth orbit satellite cannot be switched to in time, resulting in communication interruption of the terminal communication device or a decrease in the communication quality and communication stability of communication information of real-time communication types, and the normal communication of the terminal communication device cannot be guaranteed.

Detailed implementation manners

[0062] The following will further describe the present application in detail with reference to the Figures 1-6 accompanying drawings.

[0063] To make the objectives, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are some but not all of the embodiments of the present application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present application without creative efforts shall fall within the protection scope of the present application.

[0064] The embodiments of the present application provide a low-earth and high-earth orbit satellite integrated communication method, which can be executed by an electronic device. Among them, the electronic device can be a server or a terminal device. Among them, the server can be an independent physical server, a server cluster or a distributed device composed of multiple physical servers, or a cloud server providing cloud computing services; the server can be installed on a low-earth orbit satellite or on a ground communication base station. The terminal device can be a computer or the like, but is not limited thereto. The terminal device and the server can be directly or indirectly connected through wired or wireless communication methods, and the embodiments of the present application do not make limitations here.

[0065] Refer to Figure 1 , a low-earth and high-earth orbit satellite integrated communication method includes: step S101, step S102, and step S103, where

[0066] S101, determine the first communication coverage range of the current low-earth orbit satellite, the second communication coverage range of the target low-earth orbit satellite, and obtain the location information of the terminal communication device.

[0067] In some embodiments, the first communication coverage range is the coverage range within which the current low-earth orbit satellite can establish a communication connection with the terminal device; the second communication coverage range is the coverage range within which the target low-earth orbit satellite can establish a communication connection with the terminal device; the running directions of the current low-earth orbit satellite and the target low-earth orbit satellite are the same; the location information is the location where the terminal communication device is currently located.

[0068] In some embodiments, the electronic device obtains the running information of the current low-earth orbit satellite that is providing communication services for the terminal communication device and the target low-earth orbit satellite that is about to provide communication services for the terminal communication device, where the running information includes running direction, running speed, running altitude, satellite communication elevation angle, etc.; the satellite communication elevation angle refers to the angle between the parallel line starting from the terminal communication device and the line connecting the terminal communication device and the low-earth orbit satellite; for example, the lower the satellite communication elevation angle between the terminal communication device and the low-earth orbit satellite, the lower and more unstable the communication quality between the terminal communication device and the low-earth orbit satellite; therefore, generally, a minimum satellite communication elevation angle is set between the low-earth orbit satellite and the terminal communication. When the satellite communication elevation angle between the terminal communication device and the low-earth orbit satellite is lower than the minimum satellite communication elevation angle, it is considered that the low-earth orbit satellite cannot establish a communication connection and provide communication services for the terminal communication device; the electronic device determines the first communication coverage range of the current low-earth orbit satellite and the second communication coverage range of the target low-earth orbit satellite by means of the constructed three-dimensional space model and based on the satellite communication elevation angle.

[0069] In some embodiments, the terminal communication device can be positioned by means of the GPS global positioning system, the Beidou satellite navigation system, etc., and the electronic device obtains the location information of the terminal communication device through the GPS global positioning system, the Beidou satellite navigation system, etc.; however, the method of positioning the terminal communication device is not limited to this, and the embodiments of the present application do not make specific limitations.

[0070] S102, determine the range relationship between the first communication coverage range and the second communication coverage range.

[0071] In some embodiments, the electronic device substitutes the first communication coverage range and the second communication coverage range into the same two-dimensional plane model, and determines the range relationship between the first communication coverage range and the second communication coverage range through the two-dimensional coordinate relationship between the two communication coverage ranges; wherein the range relationship may be that there is no intersection area between the first communication coverage range and the second communication coverage range; or there is an intersection area between the first communication coverage range and the second communication coverage range; in the case where there is an intersection area between the two, it indicates that at a certain moment, the position of the terminal communication device is simultaneously located in the first communication coverage range and the second communication coverage range, and the communication switching between the low-orbit satellites can be directly switched; in the case where there is no intersection area between the two, it indicates that when the terminal communication device is about to leave the first communication coverage range, the target low-orbit satellite in the second communication coverage range cannot provide communication services for the terminal communication device, that is, the low-orbit satellite communication switching cannot be performed, and the terminal communication device will experience communication interruption, and other communication switching schemes need to be considered to prevent the terminal communication device from experiencing communication interruption.

[0072] S103, when the location information is located at the first edge point of the first communication coverage range, determine the satellite communication switching instruction based on the range relationship, and control the target low-orbit satellite or the corresponding high-orbit satellite to provide communication services for the terminal communication device based on the satellite communication switching instruction.

[0073] In some embodiments, the first edge point is an edge point of the first communication coverage area that deviates from the running direction of the current low-orbit satellite; the satellite communication switching instruction can be a low-orbit satellite communication switching instruction or a high-orbit satellite communication switching instruction; the low-orbit satellite communication switching instruction is used to control the target low-orbit satellite to perform communication switching; the high-orbit satellite communication switching instruction is used to control the high-orbit satellite that can cover the location information of the terminal communication device to perform communication switching.

[0074] The electronic device monitors in real time the change of the position information of the terminal communication device and the first communication coverage range, and determines in real time the positional relationship between the position information of the terminal communication device and the first communication coverage range. When it is determined that the position information is located at the first edge point of the first communication coverage range, it indicates that due to the movement of the current low-earth orbit satellite and / or the terminal communication device, the terminal communication device is about to move out of the first communication coverage range. After that, the limited communication elevation angle of the current low-earth orbit satellite causes the inability to establish a communication connection with the terminal communication device. Therefore, when the position information of the terminal communication device is located at the first edge point of the first communication coverage range, low-earth orbit satellite communication handover is selected. Then, the electronic device judges the determined range relationship and determines the corresponding satellite communication handover instruction based on the judgment result. Subsequently, the electronic device controls the corresponding low-earth orbit satellite or geostationary orbit satellite to provide communication services for the terminal communication device based on the satellite communication handover instruction. Thus, the occurrence of communication interruption of the terminal communication device during the handover between low-earth orbit satellites is reduced, and the communication quality of the terminal communication device is improved.

[0075] An embodiment of the present application provides a low-earth orbit and geostationary orbit satellite integrated communication method. The electronic device obtains the operation information of the current low-earth orbit satellite and the target low-earth orbit satellite, such as the operation direction, operation speed, operation position, and satellite communication elevation angle, etc. The electronic device determines the first communication coverage range of the current low-earth orbit satellite and the second communication coverage range of the target low-earth orbit satellite based on the operation information such as the satellite communication elevation angle by using the constructed three-dimensional space module. Subsequently, the electronic device determines the range relationship between the two based on the two-dimensional coordinates of the first communication coverage range and the second communication coverage range by using the constructed two-dimensional plane model. Then, the electronic device monitors in real time the relative position of the position information of the terminal communication device and the first communication coverage range. When it is monitored that the position information is located at the first edge point of the first communication coverage range, it indicates that low-earth orbit satellite communication handover is required to provide satellite communication services for the terminal communication device at this time. Immediately, the electronic device generates a corresponding satellite communication handover instruction based on the range relationship and sends the satellite communication handover instruction to the corresponding low-earth orbit satellite or geostationary orbit satellite to control the low-earth orbit satellite or geostationary orbit satellite to provide communication services for the terminal communication device.

[0076] In step S103, determining the satellite communication handover instruction based on the range relationship and controlling the target low-earth orbit satellite or the corresponding geostationary orbit satellite to provide communication services for the terminal communication device includes: when the range relationship is a preset range relationship, determining the duration for the second edge point of the second communication coverage range to reach the position information; when the duration is greater than the preset duration, generating a geostationary orbit satellite communication handover instruction and controlling the geostationary orbit satellite to provide communication services for the terminal communication device based on the geostationary orbit satellite communication handover instruction.

[0077] In some embodiments, the electronic device presets a range relationship in advance, and the preset range relationship is that there is no overlapping area between the first communication coverage range and the second communication coverage range; the second edge point is the edge point on the side close to the running direction of the target low-earth orbit satellite.

[0078] When the range relationship is the preset range relationship, it indicates that there is no overlapping area between the first communication coverage range of the current low-earth orbit satellite and the second communication coverage range of the target low-earth orbit satellite. At this time, it is impossible to switch to the target low-earth orbit satellite to provide communication services for the terminal communication device. Therefore, it is necessary to consider whether the geostationary satellite temporarily provides communication services during the period before switching to the target low-earth orbit satellite; because the geostationary satellite has a wide coverage range, the number of terminal communication devices provided with communication services is large, and the communication volume is large. Under non-essential circumstances, the geostationary satellite is not selected to provide communication services for the terminal communication device, unless the interruption time of the terminal communication device is too long; so when there is no overlapping area between the first communication coverage range and the second communication coverage range, it is necessary to judge the time when the second communication coverage range can cover the terminal communication device, that is, when the range relationship of the electronic device is the preset range relationship, determine the duration when the second edge point of the second communication coverage range reaches the position information, and judge the duration; the electronic device calls the preset duration and compares the duration with the preset duration. When the duration is greater than the preset duration, it indicates that the time required for the second communication coverage range to cover the terminal communication device exceeds the acceptable duration range. At this time, the geostationary satellite that can provide communication services for the terminal communication device needs to be used for communication. Immediately, the electronic device generates a geostationary satellite communication switching instruction and sends the geostationary satellite communication switching instruction to the geostationary satellite to control the geostationary satellite to temporarily provide communication services for the terminal communication device.

[0079] In some embodiments, wait until the second edge point of the second communication coverage range reaches the position information of the terminal communication device; then switch the geostationary satellite to the target low-earth orbit satellite, and the target low-earth orbit satellite provides communication services for the terminal communication device.

[0080] In some embodiments, referring to Figure 2 , there is no overlapping area between the first communication coverage range 1 and the second communication coverage range 2. When the position information 3 of the terminal communication device is located at the first edge point 4, it is necessary to switch the low-earth orbit satellite. However, since there is no overlapping area between the first communication coverage range 1 and the second communication coverage range 2, the final communication switching method of the low-earth orbit satellite needs to be determined based on the duration when the second edge point 5 reaches the position information 3 and the information level of the communication information.

[0081] In some embodiments, after determining the duration for the second edge point of the second communication coverage to reach the position information, the following steps are further included: when the duration is less than a preset duration, determining the communication level of the communication information of the terminal communication device; when the communication level is less than a preset communication level, generating a low-earth orbit satellite communication handover instruction; when the second edge point of the second communication coverage reaches the position information, sending the low-earth orbit satellite communication handover instruction to the target low-earth orbit satellite to control the target low-earth orbit satellite to provide communication services for the terminal communication device.

[0082] In some embodiments, when the second communication coverage still needs this duration of operation to cover the terminal communication device and this duration is the duration acceptable for communication interruption, at this time, communication handover can be performed when the second communication coverage covers the terminal communication device, and communication services are provided by the target low-earth orbit satellite. However, in this case, the importance level of the communication information of the terminal communication device also needs to be considered. When the importance level is relatively high, the communication information also needs to be transmitted in a timely manner. Therefore, when the electronic device determines that the duration is less than the preset duration, it determines the communication level of the communication information of the terminal communication device; the electronic device compares the communication level with the preset communication level. When the communication level is less than the preset communication level, it indicates that the importance level of the communication of the terminal communication device is relatively low, and transmission can be delayed. Then, when the second communication coverage covers the terminal communication device, the electronic device generates a low-earth orbit satellite communication handover instruction and sends the low-earth orbit satellite communication handover instruction to the target low-earth orbit satellite to control the target low-earth orbit satellite to provide communication services for the terminal communication device.

[0083] In some embodiments, when the communication level is greater than the preset level, it indicates that the importance level of the communication information of the terminal communication device is high and timely transmission is required, that is, it is necessary to switch from the current low-earth orbit satellite to other satellites to provide communication services in a timely manner. At this time, the second communication coverage of the target low-earth orbit satellite does not cover the terminal communication device, so it is impossible to switch to the target low-earth orbit satellite and provide communication services. Then, the electronic device generates a geostationary orbit satellite communication handover instruction and sends the geostationary orbit satellite communication handover instruction to the geostationary orbit satellite to provide communication services for the terminal communication device.

[0084] In some embodiments, the setting of the communication level of the communication information can be subjectively set by technicians or set according to the working attributes of the terminal communication device. For example, if the terminal communication device is used by relevant units such as research institutions and confidential enterprises, the communication level of its communication information is set to high; the communication level of the regular communication information of the terminal communication device of regular users is set to low; the present application does not make specific limitations on the setting of the communication level of the communication information.

[0085] After determining the range relationship between the first communication coverage and the second communication coverage in step S102, the following steps are further included: determining the first sub-communication coverage of the current low-earth orbit satellite and the third edge point of the first sub-communication coverage, determining the second sub-communication coverage of the target low-earth orbit satellite and the fourth edge point of the second sub-communication coverage; when the location information is at the third edge point and the range relationship is that there is an overlapping area between the first communication coverage and the second communication coverage, determining the information type of the communication information of the terminal communication device; generating a low-earth orbit satellite communication handover instruction based on the information type and the positional relationship between the third edge point and the fourth edge point, and controlling the target low-earth orbit satellite to provide communication services for the terminal communication device based on the low-earth orbit satellite communication handover instruction.

[0086] In some embodiments, the first sub-communication coverage is a partial range of the first communication coverage and is a range that supports stable communication of all types of communication information of the terminal communication device; the second sub-communication coverage is a partial range of the second communication coverage and is a range that supports stable communication of all types of communication information of the terminal communication device.

[0087] While low-earth orbit satellites support the transmission of delay communication information such as text messages and voice messages, they also support the transmission of real-time communication information such as voice calls and video calls; however, limited by the satellite communication elevation angle, there are situations where the communication quality in some areas of the communication coverage is low and unstable. Transmitting delay communication information in this part of the area will not have a great impact on the information transmission of the terminal communication device, but it will have a certain impact on the transmission of real-time communication type communication information; therefore, during the low-earth orbit satellite communication handover process and when there is an overlapping area between two low-earth orbit satellites, in order to better ensure the transmission of communication information of different information types, the electronic device needs to clarify the range of stable communication and the communication type during the low-earth orbit satellite communication handover process.

[0088] In some embodiments, the electronic device first determines the first sub-communication coverage range of the current low-orbit satellite and the third edge point of the first sub-communication coverage range, the third edge point being the edge point on the side away from the running direction of the current low-orbit satellite, and at the same time determines the second sub-communication coverage range of the target low-orbit satellite and the fourth edge point of the second sub-communication coverage range, the fourth edge point being the edge point on the side close to the running direction of the target low-orbit satellite; then, the electronic device determines the positional relationship between the position information and the third edge point in real time, and when the position information is located at the third edge point and the range relationship is that there is an intersection area between the first communication coverage range and the second communication coverage range, it indicates that it is necessary to further determine the low-orbit satellite communication switching method through the communication type of the communication information, and then the electronic device determines the communication type of the terminal communication device; and based on the information type, the positional relationship between the third edge point and the fourth edge point, generates a low-orbit satellite communication switching instruction, and sends the low-orbit satellite communication switching instruction to the target low-orbit satellite, and controls the target low-orbit satellite to provide communication services for the terminal communication device.

[0090] In some embodiments, generating a low-earth orbit satellite communication handover instruction based on the information type and the positional relationship between the third edge point and the fourth edge point includes: when the information type is a real-time communication type and the third edge point coincides with the fourth edge point, it indicates that the communication information of the terminal communication device needs to ensure a stable transmission environment. At this time, the terminal communication device is about to move out of the area of the stable transmission environment of the current low-earth orbit satellite, that is, the first sub-communication coverage area, and is about to enter the area of the stable output environment of the target low-earth orbit satellite, that is, the second sub-communication coverage area, meeting the conditions for handover of low-earth orbit satellite communication.
