[0134] In order to enable those skilled in the art to better understand the embodiments of the present application, the following description is first made.

[0135] (1) 6G distributed network;

[0136] The core idea of ​​6G networking design is the Distributed Autonomous Network (DAN) architecture, which realizes the transformation of network architecture from centralized to centralized + distributed collaborative mode. The core idea of ​​DAN is the on-demand expansion of homogeneous distributed nodes to meet the 6G wide-area, multi-scenario, on-demand access requirements. The distributed small cloud unit (SCU) is the most critical module unit of the DAN architecture. It is characterized by being distributed, autonomous, self-contained, and having a consistent organizational framework. It can be customized, established on demand, and quickly networked.

[0137] (2) Scenario-customized 6G distributed network;

[0138] From a technical perspective, especially based on the performance indicator requirements, the industry has proposed three types of application scenarios for 5G networks, including enhanced mobile broadband (eMBB), massive machine type communication (mMTC) and ultra-reliable & low-latency communication (uRLLC). In related technologies, five typical 6G scenarios, including super wireless broadband, ultra-large-scale connection, extremely reliable communication, inclusive intelligent services, and communication perception fusion, have been proposed based on the three major scenarios of 5G. Compared with 5G networks, the application scenarios of 6G in the future will be more diversified, which can be reflected in aspects such as the user groups (such as the general public and enterprises), the environment of use (such as industrial parks and homes), business needs (such as meeting basic communication needs and realizing XR games), and network needs (such as super wireless bandwidth and communication perception fusion). In addition, with the popularization of smart devices, individual-centered personalized needs will become more and more prominent, which can be reflected in scenarios such as home, work, campus, going out, sports, health, consumption, and entertainment. In addition to 2B (To Business), 2C (To Consumer) and 2H (To Home), the potential use scenarios of 6G in the future may also include 2P (To Person), that is, use scenarios centered on individuals such as body area networks and personal Internet of Things, and even various unforeseen new scenarios that may emerge with the rapid development of society. In summary, 6G networks should support various application scenarios including 2C, 2B, 2H, and 2P.

[0139] Future 6G application scenarios will put forward differentiated requirements on the network in terms of functions, performance, security, deployment, access, and management. For example:

[0140] Functional requirements: The overall network functional requirements of 6G will expand from "communication connection" to "synesthesia and intelligent computing". For example, perception and intelligence related functions are required for perception scenarios, perception related functions are required for holographic application scenarios, and data related functions are required for data service scenarios;

[0141] Performance requirements: 6G performance requirements will be improved on the basis of 5G, and will be expanded in terms of perception, intelligence, computing, etc. For example, industry subnet scenarios have ultra-high deterministic requirements in remote control, and digital twin application scenarios (data service scenarios) have ultra-large-scale connection requirements in full data collection;

[0142] Security requirements: In the future, 6G networks will be more secure and reliable, fully protect user privacy, and enhance business security capabilities. For example, data service scenarios have data security requirements in terms of data transmission and data storage, and industry subnet scenarios have link security requirements in terms of machine control;

[0143] Deployment requirements: Scenario-based deployment requires the network architecture design to be flexible enough to adapt to various scenario-based requirements. For example, in the case of perception intelligence scenarios, there is a need for local deployment in terms of fast artificial intelligence (AI) processing;

[0144] Access requirements: Diversified scenarios require dynamic ubiquitous access, which can be reflected in access location, access standard, direct / indirect access, etc. For example, in the connection service scenario, there is a need for multiple access methods in the air, ground and space in terms of wide coverage network deployment, and in the adjacent network scenario, there is a need for relay access in order to improve communication quality;

[0145] Management requirements: 6G requires a more flexible management method to adjust the network to quickly meet scenario requirements. For example, industry subnet scenarios have management requirements for enterprise self-operation and maintenance.

[0146] Therefore, 6G networks need to be customized according to scenarios and support hierarchical distribution. In view of the differentiated network requirements of 6G application scenarios, 6G networks need to be customized according to the needs of the scenarios, such as flexible selection of network access methods, network function module sets, deployment locations, and required computing resources and application platforms such as Mobile Edge Computing (MEC) on demand, and provide corresponding network services to network demanders. In view of the extreme performance requirements of 6G application scenarios, the requirements for network deployment locations and security, and the trend of hierarchical distributed deployment of network-related services and resources (such as connections, data, computing power, etc.), the network or certain network functions can be placed in distributed nodes. In addition, for scenarios with common and clear requirements, network simplification can be used to meet scenario requirements, reduce resource requirements, and improve network efficiency.

[0147] (3) Intent networks perceive user needs;

[0148] Intent-driven intent networks can be implemented based on a dual closed-loop architecture of user intent closed-loop interaction and network intent closed-loop assurance. End-to-end slicing technology is used to ensure and isolate differentiated user service level agreements (SLA) requirements. Intent instances are used as the unique ID of scenario requirements to achieve unified perception and interaction of scenario requirements, and unified network services are provided to users in the scenario based on unified slicing without awareness of the underlying network configuration.

[0149] The basic process of intent-driven closed-loop self-intelligent network:

[0150] The User Case User Interface (UUI) parses the natural language of the scenario requirements input by the user, perceives the scenario requirements, forms a use case instance, and then stores the instance in the dynamic resource library (Active and Available Inventory, AAI), creates new scenario use cases through service orchestration (SO), and manages scenario use cases; at the same time, AAI sends the intention instance it has built to the Data Collection, Analytics and Events (DCAE), which monitors the latest intentions and collects the latest network status data for UUI monitoring. Based on the scenario intent data collected by DCAE, the policy module formulates the network service orchestration strategy, which is sent to the SDN-C controller through SO, and then SDN-C sends the network configuration to execute.

[0151] (1) Acquisition of scenario requirements and intentions;

[0152] Demand intent refers to a certain situation or state that the scenario wants the network to achieve, without describing how to achieve the process. There are many forms of expression of scenario demand intent, the most common of which is natural language, in addition to voice input or related GUI input. In SDN, the intent-based northbound interface has also received widespread attention. The intent-based northbound interface is committed to unifying the expression of intent and providing a unified interface for application calls.

[0153] (2) Translation of scenario requirements and strategy verification;

[0154] Intent translation decomposes the intent and converts the scenario requirements into corresponding network configuration strategies according to the content in the scenario requirements and the current network status. With the help of methods and achievements in the field of natural language processing (NLP), AI agents can be trained as an auxiliary to translate and split the semantics contained in the scenario requirements, perform keyword extraction, lexical analysis, semantic mining and other operations on the user intent of the scenario requirements, so as to obtain the network operation status expected by the user and generate network strategies using some intelligent methods.

[0155] In order to ensure that the user intention of the scenario requirements can be correctly implemented and to ensure the security of network operation, it is also necessary to verify the enforceability of the policy. The enforceability verification of the policy needs to consider three aspects: the consistency between the demand intention and the policy content, whether the policy conflicts, and the availability of the required resources. For the conflict of policies, the set theory method is used to determine whether the policy has a conflict based on the relationship between different policy matching conditions and matching spaces, and a method for resolving the conflict is given; for the verification of the consistency between the demand intention and the policy expression content, a method combining ontology and database is used to determine whether there is inconsistency between the demand intention and the network policy.

[0156] (3) Issuance and execution of scenario requirements;

[0157] The generated network policy is sent to the network twin for verification, the network is deployed in the twin, and the analysis model is used to simulate and analyze the service performance and its impact on other existing services to verify the feasibility and rationality of the policy. After verification by the network twin, the verified policy is sent to the network orchestration management. The orchestration management maps the network policy to the configuration requirements for network resources, and takes into account the scenario requirements, and performs orchestration management for business intents in different scenarios in the form of network slicing, virtual network functions or service function chains, and automatically sends the policy to the network infrastructure.

[0158] (4) Optimization and adjustment of scenario requirements and intentions;

[0159] When the policy is issued to the actual network, the orchestration management needs to monitor the network status information in real time. By using a variety of status information perception and collection methods, the service quality, network quality and other configuration parameter information at the business and resource levels can be obtained from the network, and the closed-loop feedback mechanism can be used to drive the dynamic update of the policy to achieve real-time fault discovery and timely network self-healing. In order to ensure the real-time and high efficiency of data collection and processing, network monitoring tools, SDN controllers and other means can be used to collect and calculate the required network status information in real time. Ultimately, it is ensured that the implementation of the policy meets the scenario requirements and user intentions, and the execution results of the policy are fed back to the upper intention layer.

[0160] (5) Feedback on the results of scenario requirements and intentions;

[0161] In the face of the ever-changing network status, the intent network needs to automatically optimize and adjust the strategy according to the scenario requirements and the current network status to ensure that the network always meets the scenario requirements. If the scenario requirements are not implemented correctly or are accidentally changed during network operation, it is necessary to feedback information to the upper layer in a timely manner and re-translate and re-arrange the scenario requirements according to the current network status.

[0162] The existing solutions mainly identify user needs through intent networks, that is, users input user needs in the external information input module through network commands or natural language intentions. This has high requirements on network configuration, and has not been integrated with the 6G network, and cannot meet the "simplicity" design principle of the 6G network.

[0163] The following is a detailed description of the method for perceiving user needs provided by the embodiments of the present application through some embodiments and their application scenarios in combination with the accompanying drawings.

[0164] like Figure 2 As shown, an embodiment of the present application provides a method for perceiving user needs, which is performed by a first network node, and the method includes:

[0165] Step 201: Obtain user personalized demand information based on first information sent by a second network node or second information stored by the first network node, where the first information includes at least one of personalized demand information and terminal-related information, and the second information includes terminal-related information; wherein the terminal-related information is used to determine the personalized demand information of the terminal.

[0166] In an embodiment of the present application, the above-mentioned first network node can be an existing network node in a communication network (such as a 6G network), such as an access mobility management function (AMF), a session management function, a wireless access network device, or it can be a newly added network node in the communication network, such as network function A.

[0167] Step 202: Perform demand perception based on the user's personalized demand information to obtain a perception result.

[0168] As an implementation method, based on the mapping relationship between the user's personalized demand information and the perception result, the user's personalized demand information may be mapped to obtain the perception result.

[0169] The perception result may represent the personalized network service required by the terminal. Optionally, the perception result includes personalized demand parameters corresponding to the personalized network service.

In this solution, the user's personalized demand information is obtained based on the first information sent by the second network node or the second information stored by the first network node, so that the purpose of identifying the user's demand by the network itself is achieved, and the user's demand does not need to be identified through an external information input module, which reduces the configuration of the network.

[0171] Optionally, the method of the embodiment of the present application further includes:

[0172] Send a personalized customization request to the target network function according to the perception result.

[0173] The personalized customization request is used to request a personalized network service corresponding to the perception result. Optionally, the personalized customization request includes a personalized demand parameter or the personalized customization request includes the perception result.

[0174] The target network function is a network function that can provide the personalized network service corresponding to the perception result. The personalized customization request is sent to the target network function so that the target network function can provide the personalized network service for the terminal.

[0175] In the above scheme, the user's personalized demand information is obtained based on the first information sent by the second network node or the second information stored by the first network node, so that the target network function provides the terminal with corresponding personalized network services based on the user's personalized demand information, that is, the purpose of identifying user needs by the network itself is achieved, and there is no need to identify user needs through an external information input module, thereby reducing the configuration of the network.

[0176] Optionally, the method of the embodiment of the present application further includes:

[0177] First information sent by a second network node is acquired, where the second network node includes a terminal, a wireless access network device, or a core network device.

[0254] Step 2: The UE transmits user data on the user plane path of the established PDU session, such as user behavior data, application usage, network traffic and other information.

[0260] In this embodiment, the first network node is a network function A, where the network function A may be a network element having a data analysis function, such as a data analysis function or a location management function.

[0261] like Figure 8 As shown, the process includes:

[0262] Step 1: Network function A subscribes to UE-related data from RAN by calling the Namf_EventExposure_Subscribe service operation. The subscription message carries the event ID and the relevant content to be subscribed, such as user behavior data, application usage, network traffic, etc.

[0269] Embodiment 3: Integrating artificial intelligence technology;

[0270] Artificial intelligence technologies, such as machine learning and data mining, are used to analyze and model large amounts of user data to predict and determine user needs. By training and learning user behavior data, models can be built to perceive users' possible future needs. For example, by analyzing users' historical application usage data, it is possible to infer the network resources and services that users may need in a specific scenario.

[0271] Example 3.1: By adding artificial intelligence technology to existing network functions;

[0272] The difference between this embodiment and embodiment 2.1 is that the network function A can be a network function that already exists in the current core network, and artificial skill processing technology is added in step 5 to analyze and model a large amount of user data to predict and judge user needs, and notify the corresponding target network function of the perception results.

[0273] Embodiment 3.2: Adding an artificial intelligence analysis function, in which the artificial intelligence analysis function is a first network node;

[0274] like Fig. 9 As shown, the process includes:

[0275] Steps 1 and 2: Users upload their large amounts of data (such as user behavior data, user application data, etc.) to the AI ​​analysis function through RAN and access mobility management functions;

[0276] Step 3: AI analysis function uses AI technologies (such as machine learning and data mining) to analyze and model user data, and based on the results, it can detect the network services that users may need in the future and locate the processes or network functions that require customized design.

[0279] Example 3.3: RAN service-oriented scenario;

[0280] like Fig.10 As shown, the difference between this embodiment and embodiment 3.2 is that in the RAN service scenario, the UE does not need to upload user data to the artificial intelligence analysis function through the RAN and the access mobility management function, but can directly upload user data to the artificial intelligence analysis function through the RAN.

[0281] Embodiment 4: UE context awareness;

[0282] By perceiving user needs through UE context, such as location, time, device and other factors, 6G networks can design personalized network resource allocation and application services based on the perceived results to meet the specific needs of users. For example, nearby distributed network nodes can be configured based on the user's location information to provide services with lower latency and higher rates; or network service processes and optimization algorithms can be automatically adjusted based on the device used by the user.

[0283] In this embodiment, the first network node is an access mobility management function, such as Fig.11 As shown, the process includes:

[0284] Step 1: The access mobility management function perceives user needs by analyzing the locally stored UE context (such as location, time, device and other parameters) and locates the process or network function that needs customized design;

[0285] Step 2: The access mobility management function sends a personalized customization request to the target network function, which includes the user identifier and personalized requirement parameters;

[0286] Step 3: The target network function modifies the relevant information according to the personalized requirement parameters contained in the personalized customization request and returns a personalized customization response message to the access mobility management function.

[0287] Embodiment 5: Perceiving user needs through the user plane;

[0288] Through the user plane function, the user's frequently visited DNN, traffic, single network slice selection assistance information (S-NSSAI), user location and other related behavior information are reported to the session management function, which then perceives the user's needs and applies the perception results to the subsequent PDU session establishment process.

[0289] like Fig.12 As shown, including:

[0290] Step 1: The user plane function sends an N4 Session Report message to the session management function, which carries parameters such as SUPI, PDU Session ID, user-related behavior information (DNN, traffic, S-NSSAI, user location, etc.) and user personalized requirements.

[0291] Step 2: The session management function senses the user's needs based on the information reported by the user plane function, and customizes the subsequent PDU session establishment and other processes based on the demand perception results.

[0292] Step 3: The session management function returns an N4 Session Report ACK to the user plane function.

[0293] Through the solution of this application, the 6G network can perceive user needs in real time and accurately, perform customized design based on the perceived needs, and provide users with network services and application experiences that better meet their needs.

[0299] In the embodiment of the present application, the second network node sends the first information to the first network node, and the first information includes at least one of personalized demand information and terminal related information, and the terminal related information is used to determine the personalized demand information of the terminal. In this way, the first network node can send a personalized customization request to the target network function based on the personalized demand information, that is, the target network function provides the terminal with the corresponding personalized network service. In this way, the purpose of identifying user needs by the network itself is achieved, and there is no need to identify user needs through an external information input module, which reduces the configuration of the network.

[0300] Optionally, the second network node includes a terminal;

[0308] In the case where the second network node is a core network device other than AMF, the second network node first sends a user data subscription request to AMF; AMF sends the user data subscription request to UE through the radio access network device. Then, the user data notification sent by UE is sent to AMF through the radio access network device, and AMF sends the user data notification to the second network node.

[0309] In the case where the second network node is AMF, the second network node sends the user data subscription request to the wireless access network device, and the wireless access network device sends the user data subscription request to the UE. Then the UE sends the user data notification to the AMF through the wireless access network device.

[0310] In the case that the second network node is a wireless access network device, the wireless access network device sends a user data subscription request to the terminal, and then the wireless access network device obtains a user data notification sent by the terminal.
