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

[0051] First, the terms involved in the present application are analyzed:

[0052] LEO is the abbreviation of Low Earth Orbit, which refers to an orbital height of about 400 to 2000 kilometers from the surface of the Earth. Satellites operating at this orbital height can be used for a variety of purposes, including communication, navigation, weather observation, earth resource exploration, etc. Due to their lower orbital height, low earth orbit satellites have shorter signal propagation delay and higher frequency usage efficiency, which makes them have significant advantages in providing global communication services, especially for remote area coverage. In addition, LEO satellite communication systems greatly improve system transmission performance by using 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 direct communication technology between terminals and satellites based on New Radio technology formulated by the 3rd Generation Partnership Project (3GPP) in the R17 stage. NTN technology addresses the problems of large Doppler frequency offset, large signal attenuation, and large propagation delay caused by long distance, fast movement, and wide coverage in satellite communication scenarios. Air interface enhancement protocol design. These designs include advanced technologies such as scheduling timing management, Hybrid Automatic Repeat Request (HARQ) function scheduling, uplink transmission delay compensation, and air-ground fast switching, which have basic satellite communication capabilities. NTN, as an important supplement to ground cellular communication technology, is one of the technical directions for direct satellite communication with mobile phones. By utilizing the integration of satellite communication networks and ground 5G networks, it can provide ubiquitous coverage capabilities, connect multi-dimensional space of air, sky, land, and sea, and form an integrated ubiquitous access network to enable all-scenario on-demand access.

[0054] The Non-Terrestrial Networks (NTN) based on LEO satellites uses several LEO satellites running along the orbit, and these satellites form a satellite cluster (Satellite Cluster, SC). Access satellites in the satellite cluster provide access services for user equipment (User Equipment, UE), core network satellites provide satellite core network services, and gateway satellites are connected to ground transmission gateways through satellite backhaul links.

[0055] Currently, there is no clear specification for the core network deployment of the satellite cluster in NTN, and a satellite-borne core network deployment method is urgently needed.

[0056] To solve the above method, the embodiment of the application provides a deployment method of a satellite core network, which comprises the following steps: a cluster head satellite receives cluster head network function control information i-NFC sent by a ground service control and management function G-SCMF, and configures a satellite service control and management function S-SCMF according to the cluster head i-NFC, wherein the cluster head i-NFC comprises core network configuration information; the cluster head satellite determines cluster management i-NFC through the S-SCMF, and sends the cluster management i-NFC to a cluster member satellite, wherein the cluster member satellite is connected to the cluster head satellite through an inter-satellite link, and the cluster management i-NFC comprises a satellite cluster indicated by the core network configuration information, and the satellite cluster comprises the cluster member satellite; the cluster head satellite determines cluster member network configuration i-NFC according to the core network configuration information and a network state through the S-SCMF, and sends the cluster member network configuration i-NFC to the cluster member satellite, wherein the cluster member network configuration i-NFC comprises network function configuration information corresponding to the network state.

[0057] The method can effectively manage the member satellites in the cluster through the cluster head satellite, realize self-organization and self-management of the satellite network, and realize deployment of the satellite core network.

[0058] System architecture and scenario to which the embodiment of the present disclosure is applied

[0059] Figure 1 FIG. 1 is a system architecture diagram to which a deployment method of a satellite core network according to an embodiment of the present disclosure is applied. Taking the running law of the Walker constellation as an example, three adjacent satellite orbital planes run in the same direction, and form a satellite cluster architecture of three orbits and five satellites in a certain time period. The satellites in the dashed box represent that they belong to the same satellite cluster. The cluster is composed of a cluster head satellite and multiple cluster member satellites.

[0060] The cluster head satellite is responsible for managing intra-cluster communication and coordinating the operation of the cluster member satellites, and can perform advanced network functions such as routing decision, resource allocation, and network state monitoring.

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

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

[0063] Satellites of the same cluster: satellites within the dashed box, including cluster head satellites and cluster member satellites, together constitute a working unit, which work together to provide continuous coverage and communication services.

[0064] The ground service control and management function (G-SCMF) sends cluster head network function configuration information (i-NFC) to the cluster head satellite, and the cluster head satellite configures the 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 the network state through the S-SCMF, and sends the cluster member network configuration i-NFC to the cluster member satellites.

[0065] The following describes a deployment method of a satellite core network provided by an embodiment of the application, which is as follows:

[0066] Please refer to Figure 2 As Figure 2 shown is a flowchart of a deployment method of a satellite core network provided by an embodiment of the application, which includes the following steps:

[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, and the cluster head i-NFC includes core network configuration information.

[0068] The G-SCMF can be a functional entity for managing services in the satellite network on the ground, including resource allocation, service routing and quality of service (QoS).

[0069] The cluster head i-NFC can be an indication information for instructing the cluster head satellite to be configured according to the core network configuration information, and the core network configuration information can be carried in the payload. The core network configuration information can 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 can be generated by the G-SCMF autonomously analyzing the requirements of the satellite network, including service types, network capacity, coverage range, and expected network performance indicators, and generating the core network configuration information according to the analysis results and corresponding configuration parameters. The cluster head i-NFC can also be generated by the G-SCMF receiving the core network deployment indication from the cluster head satellite.

[0070] The S-SCMF can be a functional entity for managing services in the inter-satellite satellite network, including resource allocation, service routing, and service quality. After the cluster head satellite receives the i-NFC, the cluster head satellite can use the information to configure the S-SCMF thereon, such as setting network parameters of the S-SCMF, defining service policies, and initializing network functions, etc.

[0071] In a possible implementation, 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 the cluster members through the S-NRF;

[0073] The cluster head satellite determines the core network configuration according to 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 storing configuration information and network status data of all satellites, and the cluster head satellite can use the S-NRF to collect and monitor the network status of the cluster member satellites. By querying the S-NRF, the cluster head satellite can obtain real-time network performance indicators of the cluster member satellites, including signal strength, connection quality, user traffic distribution, resource utilization, and other key information.

[0076] The cluster head satellite can analyze the network performance indicators to determine the optimal network configuration strategy for the cluster member satellites. The cluster head satellite can formulate 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 the cluster member satellites, such as resource allocation, service parameters, security settings, etc. The G-SCMF can generate core network configuration information based on this core network configuration and carry it 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, enabling the satellite network to respond more flexibly and efficiently to environmental changes and user demands. Through this collaborative mechanism, the satellite network can achieve better self-organization and self-optimization capabilities, improving overall network performance and service quality.

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

[0079] The cluster identification 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 designated cluster members. The cluster identification may include the number, name or other attributes that can uniquely identify the cluster.

[0080] The satellite type can indicate the role and function of the cluster head satellite and the cluster member satellite. 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 according to the capabilities and responsibilities of each satellite indicated by the satellite type.

[0081] The network function configuration file can contain detailed configuration parameters and settings to guide the cluster head satellite on how to configure and manage its core network functions.

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

[0083] Table 1

[0084]

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

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

[0087] Security: This part involves the security of the message, which 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 to ensure that data has not been corrupted during transmission.

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

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

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

[0092] NF Profile / NF Service Profile: Contains the configuration file or service profile of the network function (NF), which describes the specific configuration of the network function and service 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 identification 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 instruction information that guides the configuration and management of the cluster member satellites in the satellite network, and the core network configuration information can also indicate the satellite cluster to be networked, i.e., 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 the identification of the satellite cluster is carried in the cluster management i-NFC, which allows the cluster head satellite to identify which satellites belong to the same cluster, and the cluster member satellites can also determine whether they are part of the cluster head satellite management through this identification. After determining that it belongs to the part managed by the cluster head satellite, the cluster member satellite can establish a communication relationship with the cluster head satellite.

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

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

[0097] Table 2

[0098]

[0099] wherein Cluster Head Satellite ID: a unique identifier of the cluster head satellite, used for intra-cluster management and coordination of other satellites.

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

[0101] The cluster head satellite configures a 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 the S-SCMF, the method further comprises:

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

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

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

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

[0107] In this implementation, the satellite operations, administration, and maintenance function (Satellite Operations, Administration, and Maintenance, S-OAM) can be a management function on the cluster head satellite, which can continuously detect the health status 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, the S-OAM can also detect network performance indicators such as throughput, delay, packet loss rate, and signal quality to ensure that network services 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 be configured to perform management tasks such as updating network configurations, adjusting service parameters, and implementing new service policies. 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 a fault recovery process, such as reconfiguring the network, switching to a backup system, or performing remote repairs.

[0109] In one possible implementation, the cluster member satellites include a plurality of intra-cluster satellites, and the cluster head satellite obtains network states of the cluster member satellites through the S-NRF, including:

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

[0111] The cluster head satellite determines cluster member network configurations i-NFC for each intra-cluster satellite based on the network state information corresponding to each intra-cluster satellite through the S-SCMF, and sends the cluster member network configurations i-NFC to the corresponding intra-cluster satellite.

[0112] The cluster head satellite determines cluster member network configurations i-NFC for each intra-cluster satellite based on the network state information corresponding to each intra-cluster satellite through the S-SCMF, and sends the cluster member network configurations i-NFC to the corresponding intra-cluster satellite.

[0113] In this implementation, the intra-cluster satellites can be satellites determined by the cluster head satellite to form a core network within the satellite cluster. The intra-cluster satellites can be designated by the ground system or determined by the cluster head satellite based on analysis. Each satellite can provide network state information to the S-NRF, including but not limited to signal strength, resource utilization, user traffic distribution, connection quality, etc. The cluster head satellite can query the network state information corresponding to the intra-cluster satellites from the S-NRF.

[0114] The cluster head satellite determines cluster member network configurations i-NFC for each intra-cluster satellite, which can be based on specific network state information for each satellite. The cluster head satellite can consider factors such as resource allocation, service optimization, and fault recovery to ensure that each intra-cluster satellite can obtain the most suitable configuration based on its current network status, thereby achieving network optimization and efficient operation.

[0115] In one possible implementation, after the cluster head satellite obtains the network states 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 for the cluster member satellites based on the network states.

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

[0118] Based on the analysis of these network status information, the cluster head satellite evaluates the current network conditions and identifies potential issues that may affect network performance, such as congestion, weak signals, or uneven resource allocation. Subsequently, the cluster head satellite can adjust the routing strategy based on the evaluation results, which may involve redistributing data flows to avoid congested areas or selecting more optimal paths to improve data transmission efficiency and reliability. This may also require the cluster head satellite to redistribute 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 the 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 based on 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 can be the status of the cluster member satellites in terms of network load, health, quality of communication links, etc., and can be obtained by the cluster head satellite from the cluster member satellites.

[0121] The cluster member network configuration i-NFC can be indication information indicating that the cluster member satellite configures the core network function, which can include management plane, control plane and user plane functions. The S-SCMF can adjust the network configuration of the cluster member satellite in the core network configuration information according to the network state of the cluster member satellite, and carry the adjusted network configuration in the cluster member network configuration i-NFC. For example, network state monitoring can discover potential faults or performance bottlenecks. If a satellite or link is detected to be problematic, the core network configuration file can need to be updated to reroute traffic or redistribute services to ensure network stability and reliability. According to the network state, the S-SCMF can adjust the core network configuration file to achieve load balancing. If the load of some satellites or network nodes is too high, the traffic distribution can be adjusted by the configuration file to transfer part of the traffic to the nodes with lower load.
