[0023] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the drawings of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0024] It should be noted that all actions of acquiring signals, information or data in the present invention are performed in compliance with the corresponding data protection laws and policies of the country where the device is located and with the authorization given by the owner of the corresponding device.

[0025] See also Figure 1 , Figure 1 This is one of the flow charts of the slice arrangement method provided by the present invention. In this embodiment, the slice arrangement method is applied to a satellite network slice arrangement system, and the slice arrangement method includes steps S110 to S130, and each step is specifically as follows: S110: In response to the slice instance request of the user terminal, obtain the real-time resource data of the satellite network and the security level data of the user terminal.

[0026] See also Figure 2 , Figure 2 This is the second flow chart of the slice arrangement method provided by the present invention.

[0027] like Figure 2 As shown, the satellite network slicing orchestration system includes a satellite access network, a satellite transmission network and a satellite core network; when a user terminal needs to use satellite network resources, it can send a slice instance request to the satellite access network in the satellite network, and the slice instance request can carry the network slice type required by the user terminal.

[0028] In response to the slice instance request from the user terminal, the satellite access network forwards the slice instance request to the satellite transmission network; after receiving the slice instance request, the satellite transmission network forwards the slice instance request to the satellite gateway; after receiving the slice instance request, the satellite gateway applies to the slice designer for the network slice required by the user terminal based on the network slice type required by the user terminal carried in the slice instance request. At this time, the slice orchestration system can obtain the real-time resource data of the satellite network and the security level data of the user terminal through the data collection platform.

[0029] Optionally, the data collection platform can be set up in the cloud of the satellite network operator.

[0030] Specifically, the data collection platform can be connected with third-party systems to collect resource data, performance data, operation and maintenance data, complaint information, user data, signaling data, etc. from third-party systems, and collect resource data, configuration data, performance data, alarm data related to satellite access networks, satellite transmission networks, and satellite core networks, as well as relevant configuration data, business data, and basic behavior data of satellite users.

[0031] Specifically, the data acquisition platform includes a front-end acquisition unit and a data processing unit.

[0032] The front-end collection unit includes a network collection unit and a service collection unit.

[0033] The network collection unit is used to collect resource data, configuration data, performance data, and alarm data related to the satellite access network, satellite transmission network, and satellite core network, and based on Clickhouse's big data storage technology, the collected data is distributedly stored.

[0034] The front-end collection unit adopts a multi-protocol collection method to achieve docking with third-party systems, collect resource data, performance data, operation and maintenance data, complaint information, user data, signaling data, etc. from third-party systems, support incremental data collection and / or full data collection, and store user portrait data based on the MySQL database.

[0035] During the data collection process, the data collection platform can perform standardized processing on the collected data and support multiple protocols, including FTP, DB, HTTP / HTTPS protocols, etc.; among them, the collection frequency and collection exception processing can be customized according to business characteristics, and unified interface specifications can be formulated and adapted.

[0036] The data processing unit is used to perform data preprocessing such as standardization and normalization on the data collected by the front-end collection unit. For data from different sources, the data processing unit can define the data fields according to a unified specification, perform escape and normalization of the data fields, and organically associate the data of different third-party systems according to the resource data, and combine the satellite network's ephemeris data, satellite slice resource data, and user portrait data to form a slice resource-user portrait mapping relationship to ensure that the collected data can meet user needs. Slice resources can be intelligently decided and dynamically allocated according to user priority, security level data, etc., to ensure the fairness of slice services.

[0037] See also Figure 3 , Figure 3 This is the third flow chart of the slice arrangement method provided by the present invention.

[0038] like Figure 3 As shown, the real-time resource data includes satellite access network resource data, satellite transmission network resource data and satellite core network resource data.

[0039] The satellite network slicing orchestration system includes an application server, which is equipped with an AI decision-making management module, a user portrait management module, and a machine learning real-time training module.

[0040] Among them, real-time machine learning training presents algorithm management and model management of AI models, and can specify data sources, algorithm rules, and data output formats.

[0041] By combining AI algorithms with real-time data to identify user protection levels, we can identify a list of key protection users and build user profiles.

[0042] The AI ​​decision management module is deployed with a pre-trained decision model, which is used to sort out the correlation between the satellite access network resource data, satellite transmission network resource data and satellite core network resource data collected in real time. Through the pre-trained decision model, the module provides users with satellite network slice orchestration solutions, and quickly realizes the automatic generation of satellite network slice orchestration solutions based on user portraits. The AI ​​decision management module can also call the slice resource scheduling interface of the satellite access network, satellite transmission network and satellite core network to realize hierarchical support according to the security level of the user terminal and output optimization solutions.

[0043] S120: Input the real-time resource data and security level data into the pre-trained decision model to obtain the satellite network slice orchestration plan output by the decision model.

[0044] like Figure 3 As shown, the real-time resource data includes satellite access network resource data, satellite transmission network resource data and satellite core network resource data.

[0045] After obtaining the satellite access network resource data, satellite transmission network resource data, satellite core network resource data and security level data, the real-time resource data and security level data are input into the decision model pre-trained by the AI ​​decision management module to obtain the satellite network slicing orchestration plan output by the decision model.

[0046] S130: Based on the satellite network slice orchestration scheme, construct satellite network slices and allocate satellite network slices to user terminals.

[0047] The slice orchestration method provided in this embodiment obtains the real-time resource data of the satellite network and the security level data of the user terminal in response to the slice instance request of the user terminal; inputs the real-time resource data and the security level data into the pre-trained decision model to obtain the satellite network slice orchestration scheme output by the decision model; constructs satellite network slices based on the satellite network slice orchestration scheme, and allocates satellite network slices to the user terminal. In the above manner, the real-time resource data of the satellite network and the security level data of the user terminal are input into the pre-trained decision model to obtain the satellite network slice orchestration scheme output by the decision model, and then constructs satellite network slices based on the satellite network slice orchestration scheme, and allocates satellite network slices to the user terminal. In the process of satellite network slice orchestration, the automatic orchestration is realized by using an artificial intelligence model, which can effectively improve the orchestration efficiency of satellite network slices and reduce labor costs.

[0048] In some embodiments, in response to a slice instance request from a user terminal, before obtaining real-time resource data of the satellite network and protection level data of the user terminal, it also includes: obtaining user data, service data and behavior data of the user terminal; determining user portrait data of the user terminal based on the user data, service data and behavior data; based on the user portrait data, identifying the user protection level, obtaining protection level data, and generating a protection user list.

[0049] like Figure 3 As shown, in response to the slice instance request of the user terminal, before obtaining the real-time resource data of the satellite network and the security level data of the user terminal, it is also necessary to obtain the user data, service data and behavior data of the user terminal, and determine the user portrait data of the user terminal based on the user data, service data and behavior data.

[0050] Specifically, the user portrait management module of the application server can obtain user data, business data and behavior data of the user terminal, and learn and organize the user data, business data and behavior data through AI, machine learning platforms, etc. to determine the user portrait data of the user terminal.

[0051] Furthermore, based on the user portrait data, the user protection level is identified, the protection level data is obtained, and a protection user list is generated.

[0052] Among them, for each user in the protected user list, the protection level can be determined according to the user location (user terminal location) and user characteristics of the user.

[0053] In some embodiments, the satellite network slice includes a satellite access network slice, a satellite transmission network slice, and a satellite core network slice.

[0054] Based on the satellite network slicing orchestration plan, satellite network slices are constructed, and satellite network slices are allocated to user terminals, including: based on the satellite network slicing orchestration plan, satellite access network slices are constructed; the satellite access network slices contain user terminal information, access satellite information and service link information; satellite transmission network slices are constructed; satellite transmission network slices contain ground-orbit satellite information, satellite gateway information, inter-satellite link information and feeder link information; satellite core network slices are constructed; satellite core network slices contain ground management center information and data center information; based on the satellite access network slices, satellite transmission network slices and satellite core network slices, slice instance identifiers are generated; and the slice instance identifiers are sent to the user terminals so that the user terminals connect to the satellite access network slices, satellite transmission network slices and satellite core network slices based on the slice instance identifiers.

[0055] In satellite networks, low-orbit satellites move at high speed relative to the ground, satellite beam coverage changes rapidly, and there is also high-speed relative movement between satellites running in different orbits. Inter-satellite links are frequently switched, resulting in time-varying network links and topology. At the same time, the access range and service time provided by satellites are limited, and the on-board computing and storage resources are limited, resulting in possible interruption or frequent migration of user services. In addition, the user's area, access network time period, occupied bandwidth resources, and required storage and processing resources may also change dynamically. These network status updates and user demand changes make static slices no longer able to provide reliable services to users, so new network slices need to be built in real time. However, when the network topology changes, rebuilding end-to-end slices according to business needs will not only increase the slice management cost, but also cause discontinuity of slice services due to long reconstruction delays. Therefore, it is necessary to dynamically migrate failed network functions and disconnected links in slices according to satellite link changes and user business needs. When the satellite network topology changes, slice reconfiguration problems are performed according to the satellite network slice orchestration plan to reduce the slice reconfiguration overhead while ensuring slice service continuity.

[0056] Specifically, Figure 2 As shown, after obtaining the satellite network slice orchestration plan, satellite network slices are constructed based on the satellite network slice orchestration plan.

[0057] The application server is equipped with a satellite network slice orchestration module, which can collect the resource status of the satellite network in real time, build satellite access network slices, satellite transmission network slices and satellite core network slices, and build multiple dedicated, virtual and mutually isolated logical networks on general hardware devices. According to the dynamic changes of the user's resource request time, location and bandwidth requirements, different network resources can be flexibly allocated to achieve optimal utilization of system bandwidth, storage and computing resources.

[0058] Specifically, the satellite network slice orchestration module first constructs a satellite access network slice, which contains user terminal information, access satellite information, and service link information, and is used to select an access satellite for the user terminal and allocate resources for user services.

[0059] Furthermore, the satellite network slice orchestration module constructs satellite transmission network slices, which include earth-orbit satellite information, satellite gateway information, inter-satellite link information and feeder link information, and are used to select information forwarding paths for user terminals and allocate satellite network nodes and link resources.

[0060] Furthermore, the satellite network slice orchestration module constructs satellite core network slices, which contain ground management center information and data center information, orchestrate network functions for user terminals and map them to the network.

[0061] Furthermore, the satellite network slice orchestration module can generate a slice instance identifier based on the satellite access network slice, satellite transmission network slice and satellite core network slice, and return the slice instance identifier to the satellite gateway, satellite transmission network and satellite access network in sequence through the slice designer; the satellite access network can send the slice instance identifier to the user terminal.

[0062] After the user terminal receives the slice instance identifier, it can connect to the satellite access network slice, satellite transmission network slice and satellite core network slice according to the slice instance identifier.

[0063] Preferably, in the face of the larger number and more complex structure of future low-orbit satellite constellations, if centralized control is adopted, the ground control nodes will bear huge computing cache pressure. Therefore, in this application, a management architecture combining centralized control and distributed control is considered to divide the satellites in the constellation into different areas, and slice network functions and link mapping solutions are designed based on this architecture to improve the flexibility of slice construction and reduce slice mapping delay; for the same constellation, the satellite orbit and period are fixed, and the satellite service duration can be calculated based on these ephemeris data, and the slice life cycle containing these satellite nodes and links can be predicted. The slice reconfiguration strategy is designed by comprehensively considering the service duration, slice service time and migration overhead, thereby ensuring the continuity and effectiveness of slice services.

[0064] The slice orchestration method provided in this embodiment uses technologies such as big data, AI algorithms, user portrait data, and decision management to determine the user protection level based on user portrait data, and combines the real-time resource data of the satellite network to perform slice orchestration scheduling, thereby providing users with the best service.

[0065] In some embodiments, after constructing satellite network slices based on the satellite network slice orchestration plan and allocating satellite network slices to user terminals, it also includes: obtaining service evaluation data; judging whether the satellite network slices meet the needs of the user terminals based on the service evaluation data; if the satellite network slices do not meet the needs of the user terminals, optimizing the decision model based on the service evaluation data.

[0066] like Figure 3 As shown, the satellite access network sends a slice instance identifier to the user terminal. After the user terminal receives the slice instance identifier, it can connect to the satellite network slice according to the slice instance identifier. After the user uses the satellite network slice, the service evaluation data can be obtained, and based on the service evaluation data, it can be determined whether the satellite network slice meets the needs of the user terminal.

[0067] If the satellite network slice does not meet the needs of the user terminal, the decision model is optimized based on the service evaluation data.

[0068] If the satellite network slice meets the needs of the user terminal, the decision model is updated based on the service evaluation data.

[0069] In some embodiments, in response to a slice instance request from a user terminal, after obtaining the real-time resource data of the satellite network and the security level data of the user terminal, it also includes: performing data preprocessing on the real-time resource data, user data, service data, behavior data and user portrait data; storing the preprocessed real-time resource data, user data, service data, behavior data and user portrait data in a database.

[0070] After collecting relevant data through the data collection platform, the real-time resource data, user data, business data, behavior data and user portrait data can be pre-processed, and the pre-processed real-time resource data, user data, business data, behavior data and user portrait data can be stored in the database.

[0071] Specifically, the satellite network slicing orchestration system is configured with a data storage platform, which is used to store and display basic data such as satellite network resource data, configuration data, performance data, alarm data uploaded by the data acquisition platform, as well as related data such as user business data, user behavior data, and algorithm models.

[0072] Optionally, the data storage platform is deployed in the cloud of the satellite operator to store all satellite network-related data and user profile-related data. The data storage platform can be equipped with AI database servers, relational database servers and application servers.

[0073] The AI ​​database server is used to store user tag data, structured data generated by the AI ​​platform, and data related to user portraits (such as algorithm model data, user data, business data, behavior data, and user portrait data, etc.); the satellite network basic data is extracted and stored in the form of files in the Neo4J format; the structured data generated by the AI ​​platform is generated by the satellite network basic data according to the AI ​​algorithm, and is stored in the Hive database; user tag data can be synchronized to the relational database. The AI ​​database server needs to support AI computing to achieve efficient generation of user portrait data and localized computing of AI algorithm models.

[0074] Relational database server, used to store basic resource data, performance data, configuration data, alarm data, etc. of satellite access network, satellite transmission network and satellite core network.

[0075] The data collection platform can regularly extract the basic data required for network decision-making from third-party systems, and store the structured data generated by the AI ​​platform in the relational database server. The structured data is statistically summarized and stored in the database server. The relational database server can support multiple databases, including but not limited to MySql, Oracle, etc.

[0076] In some embodiments, in response to a slice instance request from a user terminal, after obtaining the real-time resource data of the satellite network and the security level data of the user terminal, it also includes: based on the real-time resource data, generating and displaying a resource distribution map and a satellite network status map of the satellite network on the front-end page; displaying user terminal distribution information, satellite motion distribution information, security mission area distribution information, ground resource distribution information, satellite network service status information and security level data on the front-end page.

[0077] The application server is also used to deploy data front-end pages after resource access and AI model training, and to centrally present data accessed from third-party systems.

[0078] Specifically, based on real-time resource data, a satellite network resource distribution map with 3D earth and satellite as the main presentation method, as well as a satellite network status map in the form of cards are generated and displayed on the front-end page; on the front-end page, user terminal distribution information, satellite movement distribution information, support mission area distribution information, and ground resource distribution information are displayed according to different display types, and according to the differentiation of user support levels, the satellite network service status information and support level data of each user are displayed separately.
