[0039] In order to make the purpose, technical solutions and advantages of the embodiments of the present disclosure clearer, the technical solutions in the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings in the embodiments of the present disclosure. The following detailed description of the embodiments of the present disclosure provided in the drawings is not intended to limit the scope of the present disclosure for protection, but merely represents selected embodiments of the present disclosure. Based on the embodiments of the present disclosure, all other embodiments obtained by those skilled in the art without making creative efforts are within the scope of protection of the present disclosure.

[0040] Building upon the three major 5G scenarios, the ITU-R has enhanced and expanded new 6G scenarios, including the integration of artificial intelligence and communications, and the integration of perception and communications. The inventors discovered that these two new 6G scenarios require additional data and computing services to provide multi-factor services such as perception and AI, as well as the computing power required for AI model training and inference.

[0041] For future 6G intelligent entities, data services, and AI-related scenarios, intelligent entity terminals can simultaneously request multi-factor services from the network, including perception, AI services, and computing power, in addition to requesting connection services. The core network needs to enhance its collaborative processing capabilities for such multi-factor services, including identification, decomposition, orchestration, and scheduling of multi-factor service requests, as well as coordination and interaction between different service management network elements in the core network. Currently, 5G networks do not support the collaborative processing of multi-factor services.

[0042] To address the problem of users in the next-generation network simultaneously requesting multi-factor services involving perception, AI services, computing power and other factors, the disclosed embodiments propose a core network perception, intelligence and computing multi-factor service collaboration solution, which supports the core network to simultaneously process multi-factor service requests such as connection, data, AI, and computing initiated by UE, and performs step-by-step service orchestration on them based on the identification and disassembly of multi-factor service requests. It also supports information and data interaction between different factor control functions, and realizes the full-process collaboration of connection, data, AI, and computing services within the core network from request, orchestration, task execution, and result exposure.

[0043] The defects of the above solutions and the proposed solutions are the results obtained by the inventor after practice and careful research. Therefore, the discovery process of the above problems and the solutions proposed in the present disclosure for the above problems below should be the contributions made by the inventor to the present disclosure during the disclosure process.

The embodiment of the present disclosure enhances the access and mobility management function on the basis of the above. Therefore, the access and mobility management function in the embodiment of the present disclosure can also be called an enhanced access and mobility management function. In addition, the embodiment of the present disclosure also adds a service orchestration function.

Figure 2 As shown, the communication system includes a terminal, an access and mobility management function, a service orchestration function and multiple element service management functions, wherein the multiple element service management functions include a data service management function.

[0046] The terminal sends a multi-factor service request to the access and mobility management function. The multi-factor service request is used to simultaneously request multiple element services including connection, data, AI, and computing from the network;

[0047] Access and mobility management functions and collaborative service orchestration functions identify and decompose multi-element service requests into multiple single-element service requests;

[0048] The service orchestration function orchestrates the logical relationships between multiple single-factor service requests, determines the feature service management function corresponding to each single-factor service request, generates the feature service task corresponding to each single-factor service request, and sends each feature service task to the corresponding feature service management function;

[0049] Each element service management function executes its own element service task, and the data service management function sends the multi-element service results to the terminal.

[0050] It should be noted that Figure 2 The access and mobility management function in the embodiment is the enhanced access and mobility management function introduced above.

[0051] In some embodiments, the multiple element service management functions include connection service management functions, data service management functions, and computing service management functions.

[0052] The disclosed embodiments can achieve end-to-end full-process collaboration of network connections, data, AI, and computing services from request, orchestration, task execution, and result exposure, and realize the automation and intelligence of the entire process from terminal request to service execution to result return, transforming network services from traditional connection-oriented to multi-factor collaborative service-oriented, which not only improves the service capabilities and flexibility of the network, but also provides a solid basic support for emerging scenarios such as intelligent body interaction, AI native network, digital twins, etc. in the future 6G era.

[0053] In some embodiments, based on the above architecture, the present disclosure also adds data service related network elements such as connection service management functions and data plane functions, as well as computing service related network elements such as computing service management functions and computing power nodes to support the collaboration and result development of multi-factor services.

It then controls this work chain to implement specific computing service functions. The Network Slice Management Function (NCSMF) also supports computing resource reporting for UEs, RANs, and compute nodes.

[0060] Computing node: A node in the network that can provide computing power.

[0061] User plane function: responsible for processing and forwarding user data.

[0062] Enhanced access and mobility management functions: In addition to being responsible for UE access and mobility management related signaling, the collaborative processing capabilities of multiple elements such as data services and connection services are enhanced for data services.

[0063] UE (User Equipment): Various terminal devices with wireless communication functions that support users to access network services.

[0064] On the basis of the above communication system and based on the same inventive concept, the embodiment of the present disclosure further provides a service collaboration method, such as Figure 4 As shown, the service collaboration method includes S401-S405.

[0065] In S401, the terminal sends a multi-factor service request to the access and mobility management function, where the multi-factor service request is used to simultaneously request multiple element services including connection, data, AI, and computing from the network.

[0066] In S402, the access and mobility management function collaborates with the service orchestration function to identify and decompose the multi-element service request to obtain multiple single-element service requests;

[0067] In S403, the service orchestration function orchestrates the logical relationships between the multiple single-element service requests, determines the element service management function corresponding to each single-element service request, and generates an element service task corresponding to each single-element service request;

[0068] In S404, the service orchestration function sends each element service task to the corresponding element service management function;

[0069] In S405 , each element service management function executes its own element service task, and the data service management function sends the multi-element service result to the terminal.

[0070] like Figure 4 As shown, the plurality of element service management functions include data service management functions. In some embodiments, the plurality of element service management functions may further include connection service management functions and computing service management functions.

[0071] The disclosed embodiments can achieve end-to-end full-process collaboration of network connections, data, AI, and computing services from request, orchestration, task execution, and result exposure, and realize the automation and intelligence of the entire process from terminal request to service execution to result return, transforming network services from traditional connection-oriented to multi-factor collaborative service-oriented, which not only improves the service capabilities and flexibility of the network, but also provides a solid basic support for emerging scenarios such as intelligent body interaction, AI native network, digital twins, etc. in the future 6G era.

[0072] In some embodiments, the terminal sends a multi-factor service request to the access and mobility management function, including: sending a multi-factor service request to the access and mobility management function based on the first NAS message or the second NAS message; wherein, the first NAS message is a NAS message newly added by the network specifically for multi-factor service requests, and the first NAS message includes the following fields: factor service type, factor service specific business type, factor service specific QoS (Quality of Service) requirements, and factor service area; the second NAS message is an existing NAS message, and the protocol configuration option field of the second NAS message records the factor service type, factor service specific business type, factor service specific QoS requirements, and factor service area.

[0073] In the embodiment of the present disclosure, the terminal sends a multi-factor service request to the enhanced access and mobility management function, including but not limited to simultaneously requesting connection, data, AI, computing and other services from the network. Specific implementation methods include: (1) Based on a dedicated NAS message for multi-factor service request: The network adds a new NAS message dedicated to multi-factor service request, which can carry connection, data (including data collection, preprocessing, AI reasoning, AI model training, etc.), and computing service requests at the same time. Specifically, fields such as "factor service type", "factor service specific business type", "factor service specific QoS requirements", and "factor service area" are added to the NAS message. (2) Based on the PCO field of the existing NAS message: The existing PCO field carries service requests for multiple elements at the same time, and the specific fields are similar to (1).

[0074] In some embodiments, the access and mobility management function collaborates with the service orchestration function to identify and disassemble the multi-factor service request to obtain multiple single-factor service requests, including: the access and mobility management function disassembles and translates the multi-factor service request into multiple single-factor service requests, each single-factor service request corresponds to an element service of connection, data, AI, and computing; the access and mobility management function sends the multiple single-factor service requests to the service orchestration function.

[0075] In some embodiments, the access and mobility management function collaborates with the service orchestration function to identify and decompose the multi-factor service request to obtain multiple single-factor service requests, including: the access and mobility management function forwards the multi-factor service request to the service orchestration function; the service orchestration function decomposes and translates the multi-factor service request into multiple single-factor service requests, each single-factor service request corresponds to an element service among connection, data, AI, and computing.

[0076] The enhanced access and mobility management function and service orchestration function in the disclosed embodiments participate in the identification and decomposition of multi-element service requests, i.e., identifying received multi-element service requests and decomposing them into multiple single-element service requests. Specific implementation methods include: (1) the enhanced access and mobility management function decomposing and translating the multi-element service requests into separate element service requests such as connection, data, and computation, and sending them to the service orchestration function; (2) the enhanced access and mobility management function forwards the multi-element service requests to the service orchestration function, which then identifies and decomposes the multi-element service requests.

[0077] In some embodiments, when the service orchestration function determines the element service management function corresponding to each single element service request, it selects the element service management function that meets the specific business type of the element service, the specific QoS requirements of the element service, and the element service area in the multi-element service request.

[0078] In the disclosed embodiment, the service orchestration function orchestrates the logical relationships between different element services based on the decomposed multiple single-element service requests, and selects the corresponding element service management functions respectively to form element service tasks for the corresponding elements. When selecting a service management function, the service management function of the corresponding element that can meet the parameters such as "element service area" and "element service specific business type" carried in the request is selected. In addition to the fields such as "element service specific business type", "element service specific QoS requirements", and "element service area" of the corresponding element, the element service task also includes information such as the instance address of other selected element management functions to facilitate subsequent information interaction and data transmission between network elements.

[0079] In some embodiments, the service orchestration function sends each element service task to the corresponding element service management function, including: the service orchestration function directly sends each element service task to the corresponding element service management function; or, multiple element service tasks are included in a task message, and the task message flows in turn between multiple element service management functions, and each element service management function identifies and processes the element service tasks related to its own elements in the task message.

[0080] In the disclosed embodiment, the service orchestration function distributes multi-element tasks between different element service management functions. There are two ways to implement task distribution: (1) the service orchestration function directly sends the service tasks of each element to the service management function of the corresponding element; (2) the service tasks of multiple elements are included in a message and circulated among the service management network elements of the multiple elements in sequence. Each element service management network element only identifies and processes the tasks related to its own element, realizing in-path processing of multi-element signaling, thereby reducing the number of multi-element service-related signaling and simplifying the process.

[0081] In some embodiments, each element service management function performs its own element service task, including: the element service management function orchestrates and selects one or more element execution functions based on the element service specific business type, element service specific QoS requirements, and element service area carried in the element service task; the element service management function controls one or more element execution functions to perform element service tasks.

[0082] In one example, the feature service task is a data collection task, and the feature service management function is a data service management function; the feature execution functions selected by the data service management function include data surface functions and data storage functions; the data service management function controls the data surface functions to complete the data collection task, and controls the data storage function to complete the data storage task.

[0083] In the disclosed embodiments, upon receiving a corresponding element service task, the service management function of each element orchestrates and selects the appropriate element execution function based on parameters such as the "element service specific business type," "element service specific QoS requirements," and "element service region" carried therein, controlling it to execute the specific element service task. For example, when the data service management function receives a "data collection" task, it orchestrates the associated network elements, such as the data plane function and data storage function, controlling them to complete specific data service tasks such as data collection and data storage.

[0084] In some embodiments, during the execution of each element service task, information and / or data are exchanged between multiple element service management functions; wherein, the information and data exchanged between multiple element service management functions include but are not limited to the PDU connection ID established by the terminal, collected data or its storage address, AI model or its storage address, and computing power node address.

[0085] In the embodiment of the present disclosure, during the execution of each element service task, information or data will be exchanged between the element service management functions to achieve collaborative processing of multiple element services. Specifically, based on the instance addresses of other element management functions carried in the element service tasks distributed by the service orchestration function, relevant multi-element execution information can be sent to other network elements or data transmission channels can be established to achieve information and data interaction. The signaling interaction between the element service management functions can also be implemented based on the SBI architecture, and the corresponding interaction mechanism needs to be registered in the NRF in the form of a service. The information or data exchanged may include but is not limited to: the PDU connection ID established by the UE, the collected data or its storage address, the AI ​​model or its storage address, the computing power node address, etc. For example, when executing the AI ​​model training task, the data management function and the computing management function need to interact with the training data storage address and the AI ​​model storage address, so that the data management function and the computing management function can collaborate to deploy the AI ​​model to be trained on the corresponding computing power node, and collaboratively implement the AI ​​model training task based on the training data.

[0086] In some embodiments, the data service management function sends a multi-factor service result to the terminal, including: when the data volume of the multi-factor service result is less than a preset threshold, sending the multi-factor service result to the terminal through a downlink NAS message; when the data volume of the multi-factor service result is greater than or equal to the preset threshold, sending the multi-factor service result to the terminal through a downlink data packet of the user plane established by the connection service; when the multi-factor service result address is returned to the terminal, sending the multi-factor service result address to the terminal through a downlink NAS message.

[0087] After the multi-factor service collaborative processing is completed, the data management function controls the return of the multi-factor service result. There are two implementation methods: (1) For multi-factor service results with small data volume, or when returning the multi-factor service result address, it can be delivered through downlink NAS messages; (2) For multi-factor service results with large data volume, the data service result can be sent to the UE through the downlink data packet of the user plane established by the connection service.

[0088] Figure 5 A service collaboration method according to an embodiment of the present disclosure is shown. Figure 5 As shown, the terminal sends a multi-factor service request to the enhanced access and mobility management function through two optional NAS messages. The enhanced access and mobility management function and the service orchestration function participate in the identification and decomposition of the multi-factor service request in two optional ways. Then, the service orchestration function arranges the logical relationships between different factor services and selects the corresponding factor service management functions respectively. The service orchestration function distributes multi-factor tasks among different factor service management functions in two optional ways. Each factor service management function arranges and executes the corresponding tasks and exchanges information or data. Finally, the data management function controls the return of the multi-factor service results in two optional ways, thereby realizing the openness of the multi-factor service results.

[0089] Figure 6 A service collaboration method in an embodiment of the present disclosure is shown, and the service collaboration method is performed by the access and mobility management function, such as Figure 6 The service collaboration method shown includes S601-S603.

[0090] In S601, a multi-factor service request is received from a terminal, where the multi-factor service request is used to simultaneously request multiple factor services including connection, data, AI, and computing from the network;

[0091] In S602, the multi-element service request is disassembled and translated into multiple single-element service requests, each of which corresponds to a service element among connection, data, AI, and computing.

[0092] In S603, multiple single-factor service requests are sent to the service orchestration function so that the service orchestration function orchestrates the logical relationship between the multiple single-factor service requests, determines the factor service management function corresponding to each single-factor service request, generates the factor service task corresponding to each single-factor service request, and sends each factor service task to the corresponding factor service management function, wherein each factor service management function executes its own factor service task, and the data service management function sends the multi-factor service results to the terminal.

[0094] Figure 7 A service collaboration method according to an embodiment of the present disclosure is shown, and the service collaboration method is executed by a service orchestration function, such as Figure 7 The service collaboration method shown includes S701-S704.

[0095] In S701, a multi-factor service request forwarded by an access and mobility management function is received. The multi-factor service request is sent by a terminal to the access and mobility management function. The multi-factor service request is used to simultaneously request multiple element services including connection, data, AI, and computing from the network.

[0096] In S702, the multi-element service request is disassembled and translated into multiple single-element service requests, each of which corresponds to a service element among connection, data, AI, and computing.

[0097] In S703, the logical relationships between the multiple single-factor service requests are arranged, and the factor service management function corresponding to each single-factor service request is determined, and the factor service task corresponding to each single-factor service request is generated;

[0098] In S704, each element service task is sent to the corresponding element service management function, so that each element service management function executes its own element service task, and the data service management function sends the multi-element service result to the terminal.

[0099] The disclosed embodiments can achieve end-to-end full-process collaboration of network connections, data, AI, and computing services from request, orchestration, task execution, and result exposure, and realize the automation and intelligence of the entire process from terminal request to service execution to result return, transforming network services from traditional connection-oriented to multi-factor collaborative service-oriented, which not only improves the service capabilities and flexibility of the network, but also provides a solid basic support for emerging scenarios such as intelligent body interaction, AI native network, digital twins, etc. in the future 6G era.

[0100] The following describes in detail the service collaboration method provided by the present disclosure through a specific example. The collaborative process of the network for the multi-factor service request of connection, data collection, AI model training and reasoning, and calculation initiated by the UE can be as follows: Figure 8 shown.

[0101] The UE sends a multi-factor service request to the enhanced access and mobility management function, which in this embodiment includes requesting connection, data collection, AI model training and reasoning, and computing services from the network. Specific implementation methods include:

[0102] (1) Dedicated NAS messages for multi-factor service requests: The network adds a new NAS message dedicated to multi-factor service requests, which can simultaneously carry connection, data (including data acquisition, pre-processing, AI reasoning, AI model training, etc.), and computing service requests. Specifically, new fields such as "factor service type", "factor service specific business type", "factor service specific QoS requirements", and "factor service area" are added to this NAS message.

[0103] (2) Based on the PCO field of the existing NAS message: The existing PCO field carries service requests of multiple elements at the same time, and the specific fields are similar to (1).

[0104] Enhanced access and mobility management functions and service orchestration functions participate in the identification and decomposition of multi-factor service requests, that is, identifying received multi-factor service requests and decomposing them into multiple single-factor service requests, including connection, data, and computing service requests. Specific implementation methods include:

[0105] (1) Method 1: The enhanced access and mobility management function decomposes and translates the multi-element service request into separate element service requests such as connection, data, and computing, and sends them to the service orchestration function.

[0106] (2) Method 2: The enhanced access and mobility management function forwards the multi-factor service request to the service orchestration function; the service orchestration function identifies and disassembles the multi-factor service request.

[0107] The service orchestration function receives the decomposed connection, data, and computing service requests, and first selects the corresponding element service management functions to form the element service tasks of the corresponding elements. The selection is based on parameters such as the "element service area" and "element service specific business type" carried in the request. The task of the connection service management function is to establish a connection session from the UE to the network, the task of the data service management function is to collect data and perform AI model training and reasoning based on the collected data, and the task of the computing service management function is to provide appropriate computing resources for the training and reasoning of the AI ​​model. Secondly, the logical relationship between different element services is orchestrated. First, the connection between the UE and the network is established, then data collection and AI model selection are performed, and finally the AI ​​model training and reasoning tasks are scheduled to the appropriate computing nodes.

[0108] The service orchestration function distributes multi-factor tasks between different factor service management functions. There are two ways to implement task distribution:

[0109] (1) The service tasks of multiple elements are included in one message and circulate in sequence among the service management network elements of multiple elements. Each element service management network element only identifies and processes the tasks related to its own element: the connection service management function receives a multi-element service task message, identifies the connection service task therein, and forwards the message to the data service management function; the data service management function receives a multi-element service task message, identifies the data service task therein, and forwards the message to the computing service management function; the computing service management function receives a multi-element service task message, identifies the computing service task therein.

[0110] (2) The service orchestration function directly sends the service tasks of each element to the service management function of the corresponding element: sending the connection service task to the connection service management function; sending the data service task (including data collection and AI tasks) to the data service management function; 4c. sending the computing service task to the computing service management function.

[0111] The connection service management function orchestrates and controls the execution of connection service tasks: the connection service management function orchestrates the selection of appropriate user plane functions; the connection service management function controls the selected user plane functions to establish a PDU connection from the UE to the network; the PDU connection ID established by the interaction between the connection service management function and the data service management function facilitates subsequent data collection and the return of multi-factor service results.

[0112] The data service management function orchestrates and controls the execution of data service tasks: the connection service management function orchestrates and selects appropriate data plane functions and data storage functions; the connection service management function sends data collection tasks to the selected data plane functions to collect the data required for AI model training and inference; the connection service management function sends AI model training and inference tasks to the selected data plane functions; the connection service management function sends data storage tasks to the selected data storage function.

[0113] The selected data plane function performs data collection tasks and performs preprocessing and conversion into a format that is convenient for subsequent AI model training and inference.

[0114] The processed collected data is stored in the data storage function.

[0115] The data plane function selects the appropriate AI model on demand based on the specific business type in the data service task.

[0116] The data service management function sends information related to the computing resources required for AI model training and inference tasks to the computing service management function.

[0117] The computing service management function arranges and selects appropriate computing nodes based on the computing power demand information received in the previous step.

[0118] The computing service management function sends computing tasks to computing power nodes.

[0119] Scheduling of AI models and data: The computing service management function initiates scheduling requests for AI models and pre-processed collected data to the data service management function; the data service management function sends the AI ​​models and pre-processed collected data stored in the data storage function to the computing power nodes; the computing power nodes perform computing tasks for AI model training and AI inference.

[0120] Store the training and inference results in the data storage function.

[0121] The data storage function sends a message that the multi-feature service result has been stored to the data service management function.

[0122] After the multi-factor service collaborative processing is completed, the data management function controls the return of the multi-factor service results. There are two ways to achieve this:

[0123] For multi-factor service results with large data volume: the multi-factor service results are sent to the UE via the downlink data packet of the user plane established through the connection service.

[0124] For multi-factor service results with a small amount of data, or when the multi-factor service result address is returned: the multi-factor service result is sent to the UE via a downlink NAS message.

[0125] The disclosed embodiments support the UE to simultaneously initiate multi-factor service requests such as connection, data, AI, and computing to the core network. The relevant functional network elements of the core network perform step-by-step service orchestration on the basis of identifying and disassembling the multi-factor service requests, support information and data interaction between different factor control functions, and return multi-factor service results, so as to realize the full-process collaboration of connection, data, AI, and computing services within the core network from request, orchestration, task execution, and result exposure.
