The terms used herein are only for the purpose of describing the embodiments of this application and are not intended to limit this application.

[0051] First, some nouns involved in this application are analyzed:

[0052] LEO is the abbreviation of Low Earth Orbit, which refers to the orbital altitude of about 400 to 2000 kilometers from the earth's surface. Satellites operating at this orbital altitude can be used for a variety of purposes, including communication, navigation, meteorological observation, earth resource exploration, etc. Due to their lower orbital altitude, low earth orbit satellites have shorter signal propagation delays and higher frequency utilization efficiency, which gives them significant advantages in providing global communication services, especially for remote areas. In addition, the LEO satellite communication system has greatly improved the system transmission performance by adopting advanced technologies such as high-performance on-board processing payloads, advanced modulation and coding, advanced multi-beam antennas, and efficient frequency reuse.

[0053] Non-Terrestrial Networks (NTN) is a terminal-satellite direct communication technology based on new air interface technology developed by the 3rd Generation Partnership Project (3GPP) in the R17 stage. NTN technology has designed an air interface enhancement protocol to address the problems of large Doppler frequency deviation, large signal attenuation and large propagation delay caused by the long distance, fast movement and wide coverage of satellite communication scenarios. These designs include advanced technologies such as scheduling timing management, hybrid automatic repeat request (HARQ) function arrangement, uplink transmission delay compensation, and fast air-to-ground switching, and have basic satellite communication capabilities. As an important supplement to terrestrial cellular communication technology, NTN is one of the technical directions for direct connection of mobile phones to satellites. By integrating satellite communication networks with terrestrial 5G networks, it can provide ubiquitous coverage capabilities, connect the multi-dimensional space of air, space, land and sea, form an integrated ubiquitous access network, and enable on-demand access in all scenarios.

[0054] Non-Terrestrial Networks (NTN) based on LEO satellites use several LEO satellites orbiting in orbit, which form a satellite cluster (SC). The access satellites in the satellite cluster provide access services for user equipment (UE), the core network satellite provides satellite core network services, and the gateway satellite is connected to the ground transmission gateway through a satellite backhaul link.

[0055] Currently, there are no clear regulations on the core network deployment of satellite clusters in NTN, and a satellite-based core network deployment method is urgently needed.

[0056] To solve the above method, an embodiment of the present application provides a method for deploying a satellite core network, the method comprising: a cluster head satellite receiving cluster head network function control information i-NFC sent by a ground service control and management function G-SCMF, and configuring a satellite service control and management function S-SCMF according to the cluster head i-NFC, the cluster head i-NFC including core network configuration information; the cluster head satellite determines the cluster management i-NFC through the S-SCMF, and sends the cluster management i-NFC to the cluster member satellites, the cluster member satellites are connected to the cluster head satellite through an inter-satellite link, the cluster management i-NFC includes a satellite cluster indicated by the core network configuration information, and the satellite cluster includes cluster member satellites; the cluster head satellite determines the cluster member network configuration i-NFC according to the core network configuration information and the network status through the S-SCMF, and sends the cluster member network configuration i-NFC to the cluster member satellites, the cluster member network configuration i-NFC includes network function configuration information corresponding to the network status.

[0057] The method configures S-SCMF by cluster head satellite according to cluster head i-NFC containing core network configuration information received from G-SCMF, and generates cluster management i-NFC and cluster member network configuration i-NFC related to the core network configuration information through S-SCMF and sends them to corresponding cluster member satellites. The cluster head satellite can effectively manage the member satellites in the cluster, realize the self-organization and self-management of the satellite network, and realize the deployment of the onboard core network.

[0058] System architecture and scenario description of the application of the embodiments of the present disclosure

[0059] Figure 1 This is a system architecture diagram used by the deployment method of the satellite core network according to the embodiment of the present disclosure. Taking the operation law of the Walker constellation as an example, the three adjacent satellite orbits run in the same direction, forming a three-orbit five-star satellite cluster architecture within a certain period of time. The satellites in the dotted box indicate that they belong to the same satellite cluster (Satellite Cluster). This cluster consists of a cluster head satellite (Satellite Cluster Head) and multiple cluster member satellites (Satellite ClusterMembers).

[0060] The cluster head satellite is responsible for managing intra-cluster communications and coordinating the operations of cluster member satellites. It can perform advanced network functions such as routing decisions, resource allocation, and network status monitoring.

[0061] Cluster member satellites are directly connected to cluster head satellites through inter-satellite links (ISL) to perform specific tasks such as data collection, transmission or relay, and can work under the command of cluster head satellites.

[0062] Intersatellite links are direct communication links between the cluster head satellite and the cluster member satellites. These links allow data to be transferred directly between satellites, improving the efficiency and reliability of the network.

[0063] Satellites in the same cluster: Satellites in the dashed box, including cluster head satellites and cluster member satellites, together form a working unit that works together to provide continuous coverage and communication services.

[0064] The ground service control and management function (G-SCMF) sends cluster head network function control information (Information-Network Function Configuration, i-NFC) to the cluster head satellite, and the cluster head satellite configures the satellite service control and management function (Satellite Service Control and Management Function, S-SCMF) according to the cluster head i-NFC; the cluster head satellite determines the cluster management i-NFC through the S-SCMF, and sends the cluster management i-NFC to the cluster member satellites connected through the inter-satellite link; the cluster head satellite determines the cluster member network configuration i-NFC according to the core network configuration information and network status through the S-SCMF, and sends the cluster member network configuration i-NFC to the cluster member satellites.

[0065] A method for deploying a satellite core network provided in an embodiment of the present application is described below. The method is as follows:

[0066] See also Figure 2 ,like Figure 2 The figure is a flow chart of a method for deploying a satellite core network provided in an embodiment of the present application, including:

[0067] Step 201: The cluster head satellite receives the cluster head i-NFC sent by the G-SCMF, and configures the S-SCMF according to the cluster head i-NFC, where the cluster head i-NFC includes core network configuration information.

[0068] The G-SCMF may be a functional entity that manages services in a satellite network on the ground, including resource allocation, service routing and Quality of Service (QoS).

[0069] The cluster head i-NFC may be indication information for instructing the cluster head satellite to configure according to the core network configuration information, and the core network configuration information may be carried in the payload. The core network configuration information may be information indicating how the satellite interacts with the ground core network and how to implement service routing and resource allocation within the satellite network. The cluster head i-NFC may be that the G-SCMF autonomously analyzes the requirements of the satellite network, including service type, network capacity, coverage, and expected network performance indicators, generates core network configuration information based on the analysis results and corresponding configuration parameters, and then generates the cluster head i-NFC. The cluster head i-NFC may also be generated by the G-SCMF receiving the core network deployment indication from the cluster head satellite.

[0070] S-SCMF can be a functional entity that manages services in the satellite network, including resource allocation, service routing and service quality. After receiving i-NFC, the cluster head satellite can use this information to configure the S-SCMF on it, such as setting the network parameters of the S-SCMF, defining service policies and initializing network functions.

[0071] In a possible implementation manner, before the cluster head satellite receives the cluster head i-NFC sent by the G-SCMF, the method further includes:

[0072] The cluster head satellite obtains the network status of cluster members through S-NRF;

[0073] The cluster head satellite determines the core network configuration based on the network status;

[0074] The cluster head satellite sends the core network configuration to the G-SCMF, so that the G-SCMF generates the cluster head i-NFC according to the core network configuration.

[0075] In this implementation, the Satellite Network Repository Function (S-NRF) can be a database that stores configuration information and network status data of all satellites, and the cluster head satellite can use S-NRF to collect and monitor the network status of cluster member satellites. By querying S-NRF, the cluster head satellite can obtain real-time network performance indicators of cluster member satellites, including key information such as signal strength, connection quality, user traffic distribution, and resource utilization.

[0076] Cluster head satellites can analyze network performance indicators to determine the best network configuration strategy for cluster member satellites. Cluster head satellites can develop a comprehensive core network configuration by optimizing resource allocation, improving network performance, ensuring quality of service (QoS) and enhancing network reliability.

[0077] The cluster head satellite can send the core network configuration to the G-SCMF to inform the ground network of its specific configuration requirements for cluster member satellites, such as resource allocation, service parameters, security settings, etc. G-SCMF can generate core network configuration information based on the core network configuration and carry the core network configuration information in the cluster head i-NFC sent to the cluster head satellite. This ensures that the generation of the cluster head i-NFC is based on the latest network status and requirements, so that the satellite network can respond to environmental changes and user needs more flexibly and efficiently. Through this collaborative mechanism, the satellite network can achieve better self-organization and self-optimization capabilities, and improve the overall network performance and service quality.

[0078] In a possible implementation manner, the bearer information of the cluster head i-NFC includes a cluster identifier, a satellite type, and a network function configuration file.

[0079] The cluster identifier can be a unique identifier used to distinguish different satellite clusters. It helps the cluster head satellite identify the satellite cluster members it manages and ensures that the configuration information is correctly delivered to the specified cluster members. The cluster identifier may include the cluster number, name or other attributes that can uniquely identify the cluster.

[0080] The satellite type can indicate the roles and functions of the cluster head satellite and cluster member satellites. This can include whether they are responsible for specific network functions such as user data transmission, control signal processing, or network management tasks. The cluster head satellite can allocate appropriate network resources and tasks based on the capabilities and responsibilities of each satellite indicated by the satellite type.

[0081] The network function profile may contain detailed configuration parameters and settings for instructing the cluster-head satellite on how to configure and manage its core network functions.

[0082] The data structure of the cluster head i-NFC may be as shown in Table 1, and may include an NFC header (NFC header) and an NFC body (NFC body).

[0083] Table 1

[0084]

[0085] Among them, Destination Satellite ID: This part contains the identifier of the target satellite, which is used to specify the recipient of the NFC message.

[0086] NFC type: This specifies the type of NFC message, which may be used to distinguish different types of configuration messages.

[0087] Security: This part involves the security of the message and may include encryption or authentication information to ensure the security and integrity of the message.

[0088] FCS (Frame Check Sequence): This is a field used for error detection, usually used to ensure that no errors occur during data transmission.

[0089] Payload: This is the main part of the NFC message and contains the actual configuration data.

[0090] Cluster ID: A unique identifier for a satellite cluster, used to distinguish different satellite clusters.

[0091] Satellite Type: Indicates the type of satellite, which may be related to the function or role of the satellite, such as cluster head satellite or cluster member satellite.

[0092] NF Profile / NF Service Profile: Contains network function (NF) profiles or service profiles, which describe in detail the specific configuration of network functions and services that the satellite needs to perform.

[0093] Step 202: The cluster head satellite determines the cluster management i-NFC through the S-SCMF, and sends the cluster management i-NFC to the cluster member satellites. The cluster member satellites are connected to the cluster head satellite through inter-satellite links. The cluster management i-NFC includes the identifier of the satellite cluster indicated by the core network configuration information, and the satellite cluster includes the cluster member satellites.

[0094] The cluster management i-NFC can be the indication information for guiding the cluster member satellites to configure and manage in the satellite network. The core network configuration information can also indicate the satellite cluster to be networked, that is, the core network configuration information can carry the identification of the satellite cluster. The S-SCMF can determine the satellite cluster to be networked and carry the identification of the satellite cluster in the cluster management i-NFC. The identification allows the cluster head satellite to identify which satellites belong to the same cluster. The cluster member satellite can also use this identification to determine whether it is part of the cluster head satellite management. After determining that it is part of the cluster head satellite management, the cluster member satellite can establish a communication relationship with the cluster head satellite.

[0095] The bearer information of cluster management i-NFC may include cluster identification, satellite type and cluster head satellite identification. The cluster head satellite identification may be the unique identity of the cluster head satellite, so that other satellites in the cluster can identify it and establish communication and cooperation relationships with it.

[0096] The data structure of the cluster management i-NFC may be as shown in Table 2, and may include an NFC header and an NFC body.

[0097] Table 2

[0098]

[0099] Cluster Head Satellite ID: a unique identifier for the cluster head satellite, used to manage and coordinate other satellites within the cluster.

[0100] In a possible implementation manner, after the cluster head satellite receives the cluster head i-NFC sent by the G-SCMF, the method further includes:

[0101] The cluster head satellite configures the satellite network storage function S-NRF according to the cluster head i-NFC;

[0102] Before the cluster head satellite determines the cluster member network configuration i-NFC according to the network status through S-SCMF, the method also includes:

[0103] The cluster head satellite obtains the network status of cluster member satellites through the satellite network storage function S-NRF.

[0104] In this implementation, the S-NRF may be used to store and manage the configuration information and status data of the satellite network. Before obtaining the network status of the cluster member satellites, the ground system may update the configuration of the S-NRF through the cluster head satellite to adapt to the latest network requirements. Configuring the S-NRF may include updating the network function configuration file of the cluster head satellite, the list of cluster member satellites, network status parameters, etc. The S-NRF after the configuration is updated can collect the network status information of the cluster member satellites, which may include key indicators such as signal strength, connection quality, resource utilization, and user traffic distribution. The cluster head satellite can generate and allocate the most suitable network configuration for the cluster member satellites based on the latest network requirements.

[0105] In a possible implementation manner, after the cluster head satellite receives the cluster head i-NFC sent by the G-SCMF, the method further includes:

[0106] The cluster head satellite configures the satellite operation management and maintenance function S-OAM according to the cluster head i-NFC. S-OAM is used to manage the cluster head satellite and cluster member satellites.

[0107] In this implementation, the Satellite Operations, Administration, and Maintenance (S-OAM) function can be a management function on the cluster head satellite, which can continuously detect the health of the satellite, including hardware status, software performance and key system parameters, to ensure the physical and functional integrity of the satellite. At the same time, S-OAM can also detect network performance indicators such as throughput, delay, packet loss rate and signal quality to ensure that the network service can meet the predetermined service level agreement (Service Level Agreement, SLA).

[0108] S-OAM can optimize network performance and extend the service life of satellites by allocating frequencies, controlling power, and managing system storage. It can also configure management tasks such as updating network configurations, adjusting service parameters, and implementing new service strategies. When a fault occurs in the network, S-OAM can quickly identify and locate the problem, diagnose the cause by analyzing monitoring data and logs, and initiate fault recovery processes, such as reconfiguring the network, switching to a backup system, or performing remote repairs.

[0109] In a possible implementation, the cluster member satellites include multiple satellites within the cluster, and the cluster head satellite obtains the network status of the cluster member satellites through S-NRF, including:

[0110] The cluster head satellite obtains the network status information corresponding to each satellite in the cluster through S-NRF;

[0111] The cluster head satellite determines the cluster member network configuration i-NFC according to the network status through S-SCMF, and sends the cluster member network configuration i-NFC to the cluster member satellites including:

[0112] The cluster head satellite determines the cluster member network configuration i-NFC corresponding to each satellite in the cluster according to the network status information corresponding to each satellite in the cluster through S-SCMF, and sends the cluster member network configuration i-NFC to the corresponding satellite in the cluster.

[0113] In this implementation, the satellites in the cluster may be satellites that constitute the core network in the satellite cluster and are determined by the cluster head satellite. The satellites in the cluster may be designated by the ground system or determined by the cluster head satellite analysis. Each satellite may provide network status information to the S-NRF, including but not limited to signal strength, resource utilization, user traffic distribution, connection quality, etc. The cluster head satellite may query the network status information corresponding to the satellites in the cluster from the S-NRF.

[0114] The cluster head satellite determines the cluster member network configuration i-NFC of each satellite in the cluster. It can formulate a personalized configuration plan based on the specific network status information of each satellite. The cluster head satellite can take into account factors such as resource allocation, service optimization, and fault recovery to ensure that each satellite in the cluster can obtain the most appropriate configuration according to its current network status to achieve network optimization and efficient operation.

[0115] In a possible implementation manner, after the cluster head satellite obtains the network status of the cluster member satellites through the satellite network storage function S-NRF, the method further includes:

[0116] The cluster head satellite adjusts the network routing to the cluster member satellites according to the network status.

[0117] In this implementation, after the cluster head satellite obtains the network status of the cluster member satellites through S-NRF, it can use this information to perform network routing adjustments to optimize the entire identified network bottlenecks, congestion points, and areas of performance degradation, and then evaluate the effectiveness of the existing routing strategy and make adjustments based on the effectiveness.

[0118] Based on the analysis of this network status information, the cluster head satellite evaluates the current network status and identifies problems that may affect network performance, such as congestion, weak signals, or uneven resource allocation. The cluster head satellite can then adjust the routing strategy based on the evaluation results, which may involve reallocating data streams to avoid congested areas or selecting better paths to improve the efficiency and reliability of data transmission. This may also require the cluster head satellite to reallocate resources, such as adjusting power output or frequency allocation, to improve the network connection quality of specific cluster member satellites. After determining the new routing strategy, the cluster head satellite can implement routing updates, such as sending new routing information to cluster member satellites, or updating the routing table on the cluster head satellite.

[0119] Step 203: The cluster head satellite determines the cluster member network configuration i-NFC according to the core network configuration information and the network status through the S-SCMF, and sends the cluster member network configuration i-NFC to the cluster member satellites. The cluster member network configuration i-NFC includes network function configuration information corresponding to the network status.

[0120] The network status may be the status of the cluster member satellites in terms of network load, health status, quality of communication links, etc., and may be obtained by the cluster head satellite from the cluster member satellites.

[0121] The cluster member network configuration i-NFC may be indication information for instructing the cluster member satellite to configure the core network function, which may include management plane, control plane and user plane functions. The S-SCMF may adjust the network configuration of the cluster member satellite in the core network configuration information according to the network status of the cluster member satellite, and carry the adjusted network configuration in the cluster member network configuration i-NFC. Exemplarily, network status monitoring can detect potential faults or performance bottlenecks. If a problem is detected with a satellite or link, the core network configuration file may need to be updated to reroute traffic or reallocate services to ensure network stability and reliability. According to the network status, the S-SCMF may adjust the core network configuration file to achieve load balancing. If the load on some satellites or network nodes is too high, the traffic distribution can be adjusted through the configuration file to transfer part of the traffic to nodes with lower load. The S-SCMF can adjust the core network configuration file according to the quality of service requirements. For example, for applications that require high bandwidth and low latency, it may be necessary to allocate resources first and set corresponding QoS parameters in the configuration file. After receiving the cluster member network configuration i-NFC, the cluster member satellite can configure the core network functions according to the network configuration, establish network connections with other satellites or ground stations, such as the establishment and configuration of inter-satellite links, and allocate necessary network resources, including frequency, bandwidth and power.

[0122] The bearer information of the cluster member network configuration i-NFC may include a network function configuration file. The data structure of the cluster member network configuration i-NFC may be as shown in Table 3, and may include an NFC header and an NFC body.

[0125] In the embodiment of the present application, the deployment interaction diagram of the satellite core network can refer to Figure 3As shown, step 301, G-SCMF creates a cluster head i-NFC. G-SCMF creates a cluster head i-NFC, which can initialize the configuration of the satellite network. Step 302, G-SCMF sends the cluster head i-NFC to the cluster head satellite. Step 303, the cluster head satellite configures itself and S-OAM&S-NRF&S-SCMF according to the cluster head i-NFC. After receiving the cluster head i-NFC, the cluster head satellite starts to configure its own system parameters and initializes the S-OAM, S-NRF and S-SCMF modules on it. These modules are used to manage the operation of the satellite, network storage and session management. Step 304, S-OAM&S-NRF&S-SCMF creates a cluster management i-NFC. Under the coordination of S-OAM, the S-NRF and S-SCMF of the cluster head satellite jointly create a cluster management i-NFC. The cluster management i-NFC can manage the configuration and operation of the satellites in the cluster to ensure that they can work together. Step 305, S-OAM&S-NRF&S-SCMF sends the cluster management i-NFC to the cluster member satellites. Step 306, after receiving the cluster management i-NFC, the cluster member satellite adjusts its own network settings according to the configuration information therein, completes the process of joining the cluster, and starts to operate as part of the cluster. Step 307, S-OAM&S-NRF&S-SCMF creates a cluster member network configuration i-NFC, which contains more detailed network settings, such as routing policies, resource allocation, and quality of service (QoS) parameters. Step 308, the cluster head satellite sends the cluster member network configuration i-NFC to the cluster member satellites to further configure network functions. Step 309, the cluster member satellite completes its network configuration according to the received cluster member network configuration i-NFC to ensure that it can operate correctly in the satellite network.

[0126] In the embodiment of the present application, the deployment process of the satellite core network can be referred to as Figure 4As shown, in step 401, the satellite network communicates normally with the ground network. Step 402, determine whether there is a need to deploy a satellite core network, if yes, execute step 403, otherwise execute step 401. The ground control center or the automated network management system will continuously monitor the key performance indicators of the satellite network, such as signal quality, bandwidth utilization, and the number of user connections. By analyzing these data, the performance of the existing network can be evaluated, and performance bottlenecks, service interruptions, or problems with reduced user service quality can be identified. Evaluate changes in user service requirements, such as new users, changes in service types, or increased service quality requirements, which may require additional support from the satellite core network. At the same time, predict the growth of network load to ensure that the network can cope with future needs. Check the existing satellite network resources, including satellite capacity, frequency resources, and power budget, to determine whether there are sufficient resources to support the newly added core network functions. Step 403, G-SCMF creates a cluster head i-NFC. The cluster head i-NFC may include the satellite's identification code, network function configuration, security parameters, operation mode, and other necessary initialization data. Step 404, G-SCMF sends the cluster head i-NFC to the cluster head satellite. Step 405, the cluster head satellite configures S-OAM&S-NRF&S-SCMF according to the cluster head i-NFC. S-OAM is responsible for the daily operation and maintenance of the satellite. According to the configuration information in i-NFC, S-OAM will be initialized to set monitoring parameters, maintenance strategies and fault response mechanisms. S-NRF, as a storage function of the satellite network, stores network configuration and status information. The cluster head satellite will configure S-NRF to store and manage the configuration data and network status of the satellites in the cluster according to the guidance in i-NFC. S-SCMF is responsible for session management and service provision. The cluster head satellite will use the information in i-NFC to configure S-SCMF, including parameters for session establishment, modification and release, as well as service policies and charging rules. Step 406, S-SCMF sends cluster management i-NFC to cluster member satellites. Step 407, cluster member satellites join the satellite cluster according to cluster management i-NFC. A communication link with the cluster head satellite can be established, such as synchronizing clocks, establishing secure connections, or configuring data transmission parameters. Step 408: S-SCMF creates a cluster member network configuration i-NFC according to the network status of the cluster member satellite and sends it to the cluster member satellite. The cluster member network configuration i-NFC may be routing strategy, resource allocation, quality of service (QoS) parameters, etc. Step 409: The cluster member satellite configures its own core network according to the cluster member network configuration i-NFC, that is, adjusts its own network settings according to the configuration information therein to ensure that it can operate correctly in the satellite network. Step 410: Determine whether the core network configuration of the satellite cluster is completed. S-OAM determines based on the network status of the cluster member satellite subscribed by S-NRF. If yes, the core network deployment is completed. Otherwise, execute step 408.
