[0052] Furthermore, in the description of the embodiments of this application, unless otherwise stated, " / " means "or". For example, A / B can mean A or B. The "and / or" in the text is merely a description of the relationship between related objects, indicating that there can be three relationships.

Thus, a feature defined with "first" and "second" may explicitly or implicitly include one or more of that feature, and in the description of the embodiments of this application, unless otherwise stated, "multiple" means two or more.

[0054] In current 6G research, the vision of NTN network evolution that integrates space, ground, and air is considered an industry consensus. The convergence of communication and remote sensing is the basic direction of NTN evolution. However, traditional satellite communication and satellite remote sensing are independent systems that have developed and evolved in parallel without forming a unified whole.

[0055] To address the aforementioned technical problems, embodiments of this application provide a satellite remote sensing communication fusion system, communication method, and electronic device. See [link to relevant documentation]. Figure 1 This is a schematic diagram of a satellite remote sensing communication fusion system provided in an embodiment of this application. The system includes: a remote sensing satellite 101, a satellite network node 102, and a ground terminal 103. The satellite network node 102 is located in the NTN satellite network, and the ground terminal is located in the NTN terrestrial network.

[0056] It is worth noting that the NTN satellite network is just one example of the satellite networks mentioned in this application. In practical applications, satellite networks are not limited to the NTN satellite network.

[0057] like Figure 1As shown, remote sensing satellite 101 communicates with satellite network node 102 through CR Interface (Communication and Remote Interface) 104. CR Interface 104 is a defined standard interface between remote sensing satellite 101 and satellite network node 102. In one embodiment, CR Interface 104 adopts the CR Interface protocol, which is designed to enable point-to-point routing between remote sensing satellite 101 and satellite network node 102, and allows one remote sensing satellite 101 to connect to one or more satellite network nodes 102 simultaneously.

[0058] Ground terminal 103 initiates a remote sensing service request, which is sent to satellite network node 102. In one embodiment, the remote sensing service request carries the address information of the target remote sensing satellite.

[0059] Satellite network node 102 receives remote sensing service requests sent by ground terminal 103 and forwards the requests to remote sensing satellite 101 via a communication-remote sensing fusion interface. In one embodiment, when there are multiple satellite network nodes 102, the satellite network node receiving the remote sensing service request from ground terminal 103 is defined as the first satellite network node. After receiving the remote sensing service request, the first satellite network node selects one or more target satellite network nodes that meet the requirements from the multiple satellite network nodes and forwards the remote sensing service request to the target satellite network node. In one embodiment, the first satellite network node determines the target remote sensing satellite based on the address information in the remote sensing service request, and then determines the optimal routing path, i.e., the forwarding link, to the target remote sensing satellite based on the ephemeris information of the target remote sensing satellite. One or more satellite network nodes in the optimal routing path are selected as target satellite network nodes. The remote sensing service request is transmitted to the target remote sensing satellite through the target satellite network node. In this embodiment, the definition of the optimal routing path is not specifically limited; it can be the routing path with the shortest time or the routing path with the best communication effect.

[0060] In this embodiment, the remote sensing satellite 101 is configured with SDRS (Software Defined Remote Sensing) functionality and a CR Interface protocol stack, such as... Figure 2 The diagram shown is an architecture diagram of the SDRS function and CR Interface protocol stack of a remote sensing satellite provided in this application.

[0061] In one embodiment, the SDRS function of the remote sensing satellite includes: equipment of RS, telemetry data processing function (RSData), and traffic model for integrated CR.

[0062] Telemetry equipment refers to the hardware or software functionalities built into remote sensing satellites for telemetry, such as visible light devices, wireless devices, and radar. Telemetry equipment is used to collect telemetry data.

[0063] The Telemetry Data Processing (RSData) function is the data processing unit of SDRS, encompassing both hardware and software aspects. This unit processes telemetry data collected from various types of telemetry devices into a unified, formatted data set. The specific format can be determined based on actual needs and is not limited here. Furthermore, AI algorithms can be incorporated into the telemetry data processing unit to achieve intelligent data processing, repair, and generation.

[0064] The Traffic Model for Integrated CR (CR) is a functional unit that redefines the format of data processed by the RS Data unit. When a remote sensing satellite receives a remote sensing service request, it redefines the format of the telemetry data to be transmitted, obtaining target data that meets the transmission requirements of the satellite network where the satellite network node is located. This target data is in the format required for satellite network transmission. The CR performs various on-demand processing on the telemetry data after RS ​​Data processing, such as data classification, segmentation, concatenation, discarding, and compression, based on the network characteristics of the satellite network, including network resources, network transmission capacity, and network load, to form a network data format suitable for satellite network transmission.

[0065] In one embodiment, the CR Interface protocol stack includes: a CR Interface IP protocol layer, a CR Interface MAC protocol layer, and a Transport for Physical Layer.

[0066] The remote sensing and communication convergence IP protocol layer can adopt the Lite IP for CR Interface. The Lite IP for CR Interface only uses the basic functions of existing IP protocols, including IP packets, IP address allocation and management, and one-to-many connections (e.g., one remote sensing satellite connecting to multiple satellite network nodes) or many-to-one connections (e.g., multiple remote sensing satellites connecting to one satellite network node). The Lite IP for CR Interface simplifies point-to-point routing communication by using short IP headers, eliminating complex routing algorithms and rate ramping / sliding window mechanisms, simplifying the IP packet header, and removing the interaction functions between the existing IP layer and traditional upper layers such as TCP or UDP. In this embodiment, the remote sensing and communication convergence IP protocol layer and the remote sensing and communication convergence MAC protocol layer are directly connected and complete the exchange of data transmission and reception. By designing a Lite IP for CR Interface to meet the point-to-point routing requirements of satellite network nodes, the protocol function of point-to-point routing via IP addresses can be achieved while reducing power consumption and memory consumption. The Lite IP for CR Interface enables connections between remote sensing satellites and satellite network nodes, and one remote sensing satellite can connect to one or more satellite network nodes simultaneously.

[0067] The MAC for CR Interface (CR Interface) protocol layer utilizes the basic MAC functions defined in 3GPP. It adds functionality for different physical media of the CR interface, providing corresponding physical media resource control and / or scheduling functions, as well as CR interface access, establishment, modification, deletion, and release functions. It also adds the ability to directly interact with the CR IP protocol layer. Specifically, the MAC protocol layer connects to the CR IP protocol layer, enabling data and control information exchange with its upper-layer CR IP protocol layer. For different physical media, it provides a unified standard for data exchange with the CR IP protocol layer and generates MAC control commands for different physical media based on the data transmission control information sent by the CR IP protocol layer, achieving on-demand data exchange on the CR interface. Additionally, it adds CR interface transmission control functions for CR interface service types.

[0068] The Transport for Physical Layer establishes physical transmission connections between remote sensing satellites and satellite network nodes through physical media, which can be microwaves, lasers, or other physical media used for inter-satellite transmission.

[0069] like Figure 3The diagram shown illustrates the architecture of an integrated communication and remote sensing protocol provided in this application. Remote sensing satellites and satellite network nodes communicate via the CR Interface protocol. Through the CR Interface simplified IP protocol, connections can be established with the base station gNB, including protocol stacks such as SDAP (Service Data Adaptation Protocol) and PDCP (Packet Data Convergence Protocol), the core network including User Plane Functions (UPF) and Control Plane Functions (AMF), and computing satellite functions.

[0070] The satellite remote sensing and communication fusion system provided in this application embodiment achieves integrated remote sensing and communication fusion by designing the functions of remote sensing satellites and communication satellites, as well as the interface protocol function for connecting remote sensing satellites and communication satellites.

[0071] Based on the same inventive concept, this application also provides a communication method for a satellite remote sensing communication fusion system, which is applied to remote sensing satellites. See [link to relevant documentation]. Figure 4 The diagram shown is a flowchart of the communication method in a satellite remote sensing communication fusion system. The specific process is as follows:

[0072] Step 401: Receive remote sensing service requests sent by satellite network nodes through the telecom and remote sensing fusion interface.

[0073] Remote sensing satellites receive remote sensing service requests from satellite network nodes via a communication-remote sensing fusion interface. Specifically, satellite network nodes use the CR Interface protocol to process the data format of the remote sensing service requests, converting it into a format that the remote sensing satellite can receive, and then send the processed remote sensing service requests to the remote sensing satellite through the communication-remote sensing fusion interface.

[0074] Step 402: Determine the telemetry data to be transmitted based on the remote sensing service request, and send the telemetry data to be transmitted to the satellite network node through the communication and remote sensing fusion interface.

[0075] Specifically, the integrated remote sensing service model is used to process remote sensing service requests. Based on the request, the telemetry data to be transmitted is determined, and then the format of this data is redefined to obtain target data that meets the transmission requirements of the target satellite network. Here, the target satellite network is the satellite network where the network node resides. It should be noted that the telemetry data to be transmitted at this point is the data processed by the telemetry data processing unit, and its format is the predefined format. The redefined target format, however, depends on the satellite network to be transmitted to. For example, if the satellite network is an NTN satellite network, the target format is a network data packet format suitable for NTN network transmission.

[0076] In one embodiment, redefining the format of the telemetry data to be transmitted specifically involves processing the data according to the network characteristics of the satellite network to obtain target data that meets the transmission requirements of the satellite network. Network characteristics include, but are not limited to, network resources, network transmission capacity, network load, network packet loss rate, and the stability of network data transmission. Data processing includes, but is not limited to, data classification, segmentation, concatenation, discarding, and compression. Data processing may also include determining the QoS (Quality of Service) indicators for the telemetry data to be transmitted in the satellite network. QoS indicators include: latency to the user, packet loss rate to the user, data packet transmission priority, data packet priority classification, and whether the data packet is important system data. After obtaining the target data, the target data is sent to the satellite network node through the telemetry and communication fusion interface.

[0077] Through the communication-remote sensing fusion interface and protocol, direct communication between remote sensing satellites and satellite network nodes can be realized. This allows satellite networks to replace relay satellites in the remote sensing system, providing network support for the transmission of remote sensing business data, reducing the construction and maintenance costs of the remote sensing system, and providing real-time data transmission support.

[0078] Based on the same inventive concept, this application also provides a communication method for a satellite remote sensing communication fusion system, which is applied to a satellite network node. See [link to relevant documentation]. Figure 5 The diagram shown is a flowchart of the communication method in a satellite remote sensing communication fusion system. The specific process is as follows:

[0079] Step 501: Receive the remote sensing service request sent by the ground terminal.

[0080] Satellite network nodes receive remote sensing service requests from ground network terminals. Ground terminals can be mobile phones, computers, ground control centers, etc.

[0081] Step 502: Using the communication and remote sensing fusion interface protocol, send the remote sensing service request to the remote sensing satellite through the communication and remote sensing fusion interface.

[0082] In one embodiment, when a satellite network node receiving a remote sensing service request is directly connected to a remote sensing satellite through a communication-remote sensing fusion interface, it can directly send the remote sensing service request to the remote sensing satellite.

[0083] In one embodiment, when multiple satellite network nodes exist, the satellite network receiving the remote sensing service request is defined as the first satellite network node. After receiving the remote sensing service request, the first satellite network node selects one or more target satellite network nodes from the multiple satellite network nodes that meet the requirements, and sends the remote sensing service request to the target satellite network node. The target satellite network node then forwards the remote sensing service request to the remote sensing satellite. Specifically, the first satellite network node obtains the ephemeris information of the remote sensing satellite based on the remote sensing service request. In one embodiment, if the remote sensing service request carries the address information of the remote sensing satellite, the target remote sensing satellite is determined based on the address information, and the ephemeris information of the target remote sensing satellite is obtained. Based on the ephemeris information, a forwarding link that meets preset conditions is determined. The forwarding link with the preset conditions can be the forwarding route link with the shortest latency or the forwarding route link with the best communication effect; there are no specific restrictions, and it is set according to actual needs. One or more satellite network nodes on the forwarding link are designated as target satellite network nodes, and the remote sensing service request is sent to the target satellite network node for forwarding. After receiving a remote sensing service request, the target satellite network node forwards the request to the remote sensing satellite.

[0084] The above methods enable direct communication between remote sensing satellites and satellite network nodes, achieving integrated service-oriented remote sensing communication.

[0085] Based on the same inventive concept, this application also provides an electronic device, such as... Figure 6 As shown, the system includes a processor 601, a communication interface 602, a memory 603, and a communication bus 604. The processor 601, communication interface 602, and memory 603 communicate with each other via the communication bus 604. The memory 603 stores computer programs. When the processor 601 executes the program stored in the memory 603, it implements the method steps of the communication method of the satellite remote sensing communication fusion system described in the previous embodiments to achieve the same technical effect.

[0086] The communication bus mentioned in the above electronic devices can be a Peripheral Component Interconnect (PCI) bus or an Extended Industry Standard Architecture (EISA) bus, etc. This communication bus can be divided into address bus, data bus, control bus, etc. For ease of illustration, only one thick line is used to represent it in the diagram, but this does not indicate that there is only one bus or one type of bus.

[0087] The communication interface is used for communication between the aforementioned electronic devices and other devices.

[0088] The memory may include random access memory (RAM) or non-volatile memory (NVM), such as at least one disk storage device. Optionally, the memory may also be at least one storage device located remotely from the aforementioned processor.
