[0002] High-throughput satellites are satellites that utilize technologies such as spot beams and frequency reuse to achieve high-capacity, high-speed communication based on limited frequency resources, and represent the future development direction of communication satellites.

[0003] To meet the service needs of different subnets, most high-throughput satellite systems deploy multiple baseband systems. In the DVB-S2 / X protocol's forward link large carrier transmission mode, different baseband systems require different satellite frequency resources. Due to significant differences in technical standards and network control modes among different baseband systems, satellite frequency resources can only be dynamically adjusted to a certain extent within the baseband system itself. Deploying multiple baseband systems within a single beam requires dividing the beam's frequency resources into independent sub-bands for allocation to each baseband system, which easily leads to resource fragmentation, failing to fully utilize the performance advantages of the large bandwidth beam, and resulting in low bandwidth resource utilization efficiency.

[0048] To make the objectives, technical solutions, and advantages of this disclosure clearer, the following detailed description is provided in conjunction with specific embodiments and the accompanying drawings.

[0049] It should be noted that, unless otherwise defined, the technical or scientific terms used in the embodiments of this application should have the ordinary meaning understood by one of ordinary skill in the art to which this disclosure pertains.

[0050] As described in the background section, high-throughput satellite systems typically deploy multiple service subnets, such as terrestrial, aerospace, and maritime subnets, with each subnet deploying its own baseband system based on service requirements. In satellite forward link transmission, frequency resources are generally allocated to each baseband system, which can easily lead to resource fragmentation issues (e.g., Figure 1 As shown), to avoid resource fragmentation, the allocated frequency resources are migrated, which can integrate idle continuous frequency resources (such as...). Figure 2 (As shown), however, resource migration can lead to business interruption.

[0051] In view of this, this application provides a method for efficient transmission of high-throughput satellite multi-baseband system resources. The method arranges the service data of each baseband system according to priority, then uniformly schedules the transmission order of the service data of each baseband system according to priority, allocates time slot resources for the service data, and transmits the service data of each baseband system according to the uniformly scheduled transmission order based on the allocated time slot resources, thereby ensuring the normal operation of each baseband system and improving the utilization rate of satellite resources.

[0052] The present application will be described in detail below with reference to the accompanying drawings and embodiments.

[0053] like Figure 3-5 As shown in the figure, this application provides a method for efficient transmission of resources in a high-throughput satellite multi-baseband system, including:

[0054] S301: Obtain service data packets from each baseband system; wherein, the service data packets are encapsulated by the baseband system based on the service data and the corresponding importance and real-time parameters of the service data;

[0055] In this embodiment, each baseband system encapsulates service data into service data packets according to a predetermined format and stores these service data packets in a service queue. In some methods, application layer service data is processed by the network layer into upper-layer Protocol Data Units (PDUs), encapsulated using Generic Stream Encapsulation (GSE) at the data link layer, and used to generate service data packets, which are then added to the service queue. Each service data packet includes a header and data content. The header includes the service data's tag, protocol type, network address, traffic category, real-time parameters, importance parameters, modulation scheme, etc. The data content mainly consists of service data. In satellite communication scenarios, service data can include multimedia data such as images, audio, and video, as well as probe data, etc. Specific services can be implemented through communication between the ground station and the satellite.

[0056] S302: Parse the business data packets to obtain importance parameters and real-time parameters;

[0057] S303: Determine the priority of each service data packet based on the importance parameter and the real-time parameter;

[0058] In this embodiment, corresponding service data packets are read from the service queues of each baseband system, and parsed according to the encapsulation format to obtain the importance parameters and real-time parameters of the service data packets. The importance parameter measures the degree of importance of the service data, while the real-time parameter measures the real-time requirements of the service data. The priority of the service data packets can be determined comprehensively based on the importance and real-time parameters.

[0059] In some methods, based on the importance of the business data, a value of 1 indicates extreme importance, 2 indicates important, and 3 indicates normal. Therefore, the importance parameter of the j-th business data packet of the i-th baseband system... It can be represented as:

[0060]

[0061] Based on the real-time requirements of business data, a real-time parameter value of 1 indicates accelerated forwarding, 2 indicates guaranteed forwarding, and 3 indicates default forwarding. Therefore, the real-time parameter of the j-th service data packet in the i-th baseband system... It can be represented as:

[0062]

[0063] Among them, DP i jZ represents the service data of the j-th service data packet of the i-th baseband system. 1 For the extremely important business set, Z 2 For the important business set, Z 3 For general business sets; R 1 To accelerate the forwarding of service sets, R 2 To ensure the forwarding service set, R 3 This is the default forwarding service set.

[0064] Calculate the priority of the j-th service data packet of the i-th baseband system based on the importance and real-time parameters. The formula is:

[0065]

[0066] After prioritizing the service data Quality of Service (QoS) based on its importance and real-time requirements, the service data packets can be sorted from highest to lowest priority, as follows:

[0067]

[0068] Among them, the smaller the priority value, the higher the priority; the larger the priority value, the lower the priority.

[0069] S304: Add each service data packet to the corresponding classification queue of each baseband system in descending order of priority;

[0070] In this embodiment, for each baseband system, service data packets are read from the service queue, and the importance and real-time parameters of each service data packet are parsed. The priority of each service data packet is calculated based on the importance and real-time parameters, and then the service data packets are sorted in descending order of priority. The sorted service data packets are then stored in a classification queue. Thus, after sorting the service data packets for each baseband system, a classification queue for each baseband system is obtained.

[0071] S305: Based on the predetermined scheduling algorithm, determine the sending order of service data packets in each classification queue, and add the service data packets to the mixed queue according to the sending order;

[0072] In this embodiment, for each baseband system's classification queue, the sending order of each service data packet in each classification queue is determined according to a scheduling algorithm, and the service data packets are added to the mixed queue according to the sending order. During scheduling, when the priorities of service data packets from different baseband systems in each classification queue are different, the sending order of service data packets is determined according to the order of priority from high to low. When the priorities of service data packets from different baseband systems in each classification queue are the same, the sending order of service data packets with the same priority is determined according to a predetermined scheduling algorithm, thereby achieving unified scheduling of the sending order of service data packets from different baseband systems. After determining the sending order of service data packets from each baseband system, the uniformly scheduled service data packets are added to the mixed queue, and the service data packets in the mixed queue are subjected to unified subsequent sending processing.

[0073] Optionally, the scheduling algorithm can use the Proportional Fairness (PF) algorithm, which selects the highest priority service data packet from each classification queue for processing at each scheduling time. Based on parameters such as the user request rate and available user data arrival time of different baseband systems, the priority values ​​of different baseband systems are calculated, and the highest priority service data packets of different baseband systems are sent in descending order of priority value.

[0074] S306: Allocate resources to each service data packet in the mixed queue according to the predetermined resource allocation algorithm;

[0075] In this embodiment, for the service data packets of each baseband system that are sorted in the transmission order in the hybrid queue, time slot resources are allocated to each service data packet according to the dynamic time slot allocation algorithm. Assuming the number of time slots is M×N, if the number of service data packets in the hybrid queue is less than the number of time slots, time slots are allocated according to the order of the service data packets in the hybrid queue, and time slots are continuously allocated to each service data packet in the hybrid queue; if the number of service data packets in the hybrid queue is greater than the number of time slots, time slots are allocated according to the order of the service data packets in the hybrid queue, and for the service data packets with lower priority that have no remaining time slots, time slot resources of the next frame are allocated.

[0076] S307: Send service data packets in the mixed queue based on the allocated resources.

[0077] In this embodiment, the sending order of service data packets of each baseband system is determined by the scheduling algorithm, and the resources allocated to each service data packet are determined by the resource allocation algorithm. Then, the service data packets in the mixed queue are sent on the allocated resources in the sending order, thereby completing the unified scheduling and resource allocation of service data of multiple baseband systems, which can improve resource utilization and make full use of the advantages of satellite resources.

[0078] In some embodiments, after determining the transmission order of service data packets and the allocated resources, the transmission of service data packets further includes:

[0079] The service data packets are modulated according to the modulation method, and a physical layer header is added to generate the baseband signal;

[0080] The baseband signal is up-converted and amplified before being transmitted via the antenna.

[0081] In this embodiment, according to the service data packets to be sent in the hybrid queue, the service data packets are subjected to physical layer modulation and coding processing using a modulation and coding system (MODCOD). After modulation and coding processing, a physical layer header is added to generate a baseband signal in the form of a physical layer frame. The baseband signal is then subjected to radio frequency processing, up-conversion, and power amplification before being transmitted to the satellite via an antenna. In this way, by uniformly performing physical layer coding and modulation processing on the service data of each baseband system in the hybrid queue and then transmitting it, the number of baseband devices required for deployment can be reduced, thus reducing system complexity.

[0082] In some embodiments, the method further includes: monitoring broadcast messages on the forward link, parsing the broadcast messages, and if the destination network address in the broadcast message is the local address, receiving and processing the broadcast message. The method of this embodiment can be applied to ground stations, which can process service data according to the aforementioned processing method and then send it to the satellite, or receive data sent by the satellite.

[0083] The high-throughput satellite baseband system resource efficiency transmission method provided in this application first sorts the service data of multiple baseband systems according to priority, then schedules the prioritized service data packets, adds the service data packets of each baseband system to a hybrid queue according to the transmission order, allocates time slot resources to each service data packet, and then performs unified physical layer modulation on each service data packet in the hybrid queue before transmitting it. Through unified scheduling and resource allocation, resource utilization can be improved, resource fragmentation can be avoided while ensuring reliable transmission of various service data, and system complexity can be reduced through unified physical layer coding and modulation processing.

[0084] It should be noted that the method in this embodiment can be executed by a single device, such as a computer or server. The method can also be applied in a distributed scenario, where multiple devices cooperate to complete the task. In such a distributed scenario, one of these devices may execute only one or more steps of the method in this embodiment, and the multiple devices will interact with each other to complete the method described.
