The basis of network intelligence model training and reasoning analysis is data, and the objects of network intelligence services can be networks, network elements, terminal devices, applications, etc.

[0003] The existing 3GPP specifications or related solutions provide network intelligent services for terminal users, but there are the following problems: 1) Terminal users cannot directly request user-related network intelligent services from the network; 2) When consumers request user-related network intelligent services from the network, they need to first discover the network intelligent service element responsible for providing services to the terminal user, and need to first discover the access management element currently responsible for the terminal user and other related network elements, and the process is relatively complicated; 3) When consumers make user-related network intelligent service requests, it takes a long time to collect and analyze data to achieve the accuracy of the model, and it is difficult to guarantee the service timeliness; 4) There are many methods for training and inference of user-related network intelligent models, which need to consider information such as terminal resource capabilities and network performance. However, the current solution does not support advance analysis and selection.

[0049] In addition, the accompanying drawings are only schematic illustrations of the present disclosure and are not necessarily drawn to scale. The same reference numerals in the figures represent the same or similar parts, and their repeated description will be omitted. Some of the block diagrams shown in the accompanying drawings are functional entities and do not necessarily correspond to physically or logically independent entities. These functional entities can be implemented in software form, or implemented in one or more hardware modules or integrated circuits, or implemented in different networks and / or processor devices and / or microcontroller devices.

[0050] It should be noted that the ordinal numbers such as "first" and "second" mentioned in the embodiments of the present disclosure are used to distinguish multiple objects, and are not used to limit the order, timing, priority or importance of multiple objects, and the descriptions of "first" and "second" do not limit the objects to be different.

[0051] The existing 3GPP specifications or related solutions provide network intelligent services for terminal users, but there are the following problems: 1) Terminal users cannot directly request user-related network intelligent services from the network; 2) When consumers request user-related network intelligent services from the network, they need to first discover the network intelligent service element responsible for providing services to the terminal user, and need to first discover the access management element currently responsible for the terminal user and other related network elements, and the process is relatively complicated; 3) When consumers make user-related network intelligent service requests, it takes a long time to collect and analyze data to achieve the accuracy of the model, and it is difficult to guarantee the service timeliness; 4) There are many methods for training and inference of user-related network intelligent models, which need to consider information such as terminal resource capabilities and network performance. However, the current solution does not support advance analysis and selection.

[0052] In order to solve the above problems, the embodiments of the present invention provide a communication method, which determines the network intelligent service network element that provides network intelligent services for the terminal device when the terminal device accesses the network, and then establishes an association between the terminal device, the target network element and the selected network intelligent service network element in the registration and session processes. Subsequently, based on the established association, the network intelligent service network element can provide network intelligent services to the terminal device.

[0053] It can be seen that in the communication method of the embodiment of the present disclosure, the network intelligent service related to the user is endogenous to the network. When the terminal device accesses the network, its exclusive network intelligent service is determined, and the network intelligent service is associated through registration, session and other processes, supporting the terminal device to directly obtain network intelligent services, improving the user-centric intelligent service experience, and also improving the subsequent network intelligent service data acquisition, service efficiency and experience; and based on the established association, it can know the resource capabilities, network performance and other information of the terminal device in advance, which is convenient for the training of the network intelligent service and the selection of the reasoning method, and can collect necessary data and start autonomous network intelligent services in advance based on the established association, thereby improving the accuracy and efficiency of the network intelligent service.

It should be noted that the specific type of the core network element is not limited in the embodiments of the present disclosure.

[0057] Optionally, the client of the application installed in different terminal devices is the same, or the client of the same type of application based on different operating systems. Based on the different terminal platforms, the specific form of the client of the application can also be different, for example, the application client can be a mobile client, a PC client, etc.

[0058] In the disclosed embodiment, the terminal device 101, as a consumer of user-level network intelligent services, can use the network intelligent services provided by the network, provide data required for the network intelligent services, and perform collaborative training or reasoning based on the network intelligent services.

[0059] The network intelligent service network element 102 provides user-level exclusive network intelligent services for the terminal device 101, and can collect data from the terminal device, perform model training or reasoning, etc.

[0060] The access and mobility management network element 103 is responsible for registering the terminal device 101, discovering the network intelligent service network element 102, and transmitting information to other network elements. The access and mobility management network element 103 can also obtain network intelligent services related to users and provide information related to network intelligent services.

[0061] The policy control network element 104 is responsible for controlling terminal policies, access and mobility management policies, and session policies. It can also obtain network intelligent services related to users and provide information related to network intelligent services.

[0062] The session management network element 105 and the user plane network element 106 are responsible for establishing the session signaling plane and the session plane, and can also obtain network intelligent services related to the user, provide information related to the network intelligent services, etc.

[0063] The data management network element 107 is responsible for providing the contract data of the terminal device, including network intelligent service authorization information, privacy requirements, etc.

[0064] Other consumers 108 can obtain user-related network intelligent services, which may specifically include various network elements, application layers, radio access network (Radio Access Network, RAN) network elements and operation, maintenance and management (Operation Administration and Maintenance, OAM) entities in the network.

[0065] It should be noted that the communication method provided by the embodiments of the present disclosure can be applied to 5G / 6G and later scenarios; each network element in the above system architecture can be a physical entity, a module embedded in other network elements, or a service with specific logic. For example, the network intelligent service network element can be a network intelligent service, the access and mobility management network element can be an access and mobility management service, the policy control network element can be a policy control service, the session management network element can be a session management service, the user plane network element can be a user plane service, and the data management network element can be a data management service. For the convenience of description, the network element is used for explanation in the embodiments of the present disclosure.

[0066] Those skilled in the art will know that Figure 1 The number of terminal devices and network elements in the figure is only for illustration, and any number of terminal devices and network elements may be provided according to actual needs, which is not limited in the embodiments of the present disclosure.

[0067] Figure 2 A flow chart of a communication method in an embodiment of the present disclosure is shown. Figure 2 The communication method shown in the embodiment can be applied to a core network element and may include steps S210 to S230.

[0068] Step S210: When a terminal device accesses a network, a network intelligent service network element that provides network intelligent services for the terminal device is determined.

[0069] Among them, the target network elements may include various related network elements, for example, network elements related to access management, mobility management, session management, policy control, location management, perception management, etc. The target network elements may also include network elements that communicate with other domains, for example, capability exposure network elements, etc.

[0070] When a terminal device accesses a network, a network intelligent service network element that provides network intelligent services for the terminal device is determined. The network intelligent service network element can provide user-related network intelligent services for the terminal device.

[0071] Step S220: In the registration and session process, an association is established between the terminal device, the target network element and the network intelligent service network element.

[0072] In the registration and session processes, the terminal device, the target network element and the determined network intelligent service network element are associated, that is, the terminal device, the target network element and the network intelligent service are associated.

[0073] Specifically, in the registration process, the association between the terminal device, the access and mobility management network element, the terminal policy control network element, the access and mobility management policy control network element and the network intelligent service network element can be established. Also, in the session establishment or session modification and other session-related processes, the association between the session management network element, the session policy control network element, the user plane network element and the network intelligent service network element can be established.

[0074] Optionally, in other processes, associations between terminal devices, other related network elements and network intelligent service network elements may also be established. For example, in processes such as location management and perception management, related network elements such as location management network elements and perception management network elements establish network intelligent service associations with network intelligent service network elements to facilitate the provision of subsequent network intelligent services. The association process is similar to the association process in the session process, and the embodiments of the present disclosure do not limit this.

[0075] Step S230: Based on the established association, network intelligent service is provided to the terminal device through the network intelligent service network element.

[0076] After establishing associations between the terminal device, the target network element and the network intelligent service network element, the network intelligent service network element can provide network intelligent services to the terminal device based on the established associations. Specifically, since the terminal device, the target network element and the network intelligent service network element are associated, the network intelligent service network element can collect data related to network intelligent services from the terminal device and the target network element, can train and reason about network intelligent service models, and can send service results, strategies and suggestions to the terminal device and the target network element.

[0077] The communication method of the disclosed embodiment internalizes the network intelligent service related to the user into the network. When the terminal device accesses the network, its exclusive network intelligent service is determined, and the network intelligent service is associated through registration, session and other processes, supporting the terminal device to directly obtain the network intelligent service, improving the user-centric intelligent service experience, and also improving the subsequent network intelligent service data acquisition, service efficiency and experience; and based on the established association, it can know the resource capabilities, network performance and other information of the terminal device in advance, which is convenient for the training of the network intelligent service and the selection of the reasoning method, and can collect necessary data and start the autonomous network intelligent service in advance based on the established association, thereby improving the accuracy and efficiency of the network intelligent service.

[0078] In order to enable ordinary persons in the art to better understand the technical solution of the present disclosure, each step of the communication method in the exemplary embodiment of the present disclosure will be described in detail below with reference to the accompanying drawings and embodiments.

[0079] In step S210, when a terminal device accesses a network, a network intelligent service network element that provides a network intelligent service for the terminal device is determined.

[0080] Figure 3 The flowchart of determining a network intelligent service network element that provides network intelligent services to a terminal device in an embodiment of the present disclosure is shown. Figure 3 As shown, the network intelligent service network element can be determined through the following steps.

[0081] Step S310: Determine to provide network intelligent services for the terminal device according to at least one of the registration request sent by the terminal device, the contract data of the terminal device, and the network default provision mode.

[0082] The disclosed embodiment discloses three ways of providing network intelligent services: according to the registration request sent by the terminal device, that is, the terminal device requires the provision of network intelligent services when accessing the network, which can be referred to as the access request method; according to the contract data of the terminal device, that is, the terminal device signs the network intelligent service association intention in the data management network element; the network default provision method, that is, it is provided by default by the network. These three ways of providing network intelligent services can be combined at will to confirm the terminal device's need to obtain network intelligent services, that is, to determine the need to provide network intelligent services for the terminal device.

[0083] Optionally, the registration request includes a network intelligent service establishment request. Further, the registration request also includes at least one of a network intelligent service type, a network intelligent service identifier, a network intelligent service capability, and a network intelligent service privacy requirement.

[0084] If the access request method is adopted, the network intelligent service establishment request information is added to the registration request sent by the terminal device, so as to indicate through the network intelligent service establishment request that the terminal device wishes to obtain the network intelligent service, thereby improving the user experience and facilitating subscription and acquisition of network intelligent service information at any time.

[0085] In addition, the registration request also includes information such as network intelligent service type, network intelligent service identifier, network intelligent service capability and network intelligent service privacy requirements. The transmission of this information indicates that the terminal device wishes to obtain specific network intelligent services.

[0086] Among them, the network intelligent service type can be understood as the type of network intelligent service, such as terminal network intelligent service, access network intelligent service, mobility network intelligent service, session network intelligent service, perception network intelligent service, positioning network intelligent service, etc., or general network intelligent service, that is, including all types of network intelligent services. In this case, the service type parameter may not be passed. The network intelligent service identifier may indicate a certain network intelligent service, which may be an analysis ID. The network intelligent service capability may include service scenarios, such as terminal mobile trajectory analysis, terminal communication behavior analysis, terminal user plane performance analysis, etc. The network intelligent service privacy requirements may include support information for network intelligent services, such as user privacy requirements, whether distributed learning and split reasoning can be supported, etc.

[0087] Optionally, the contract data includes at least one of network intelligent service authorization information, network intelligent service type, network intelligent service identification, network intelligent service capability and network intelligent service privacy requirement.

[0088] The terminal device may sign a network intelligent service association intention in advance in the data management network element, and specifically add the authorization information of the network intelligent service to the contract data of the terminal device, indicating the desire to obtain the network intelligent service through the authorization information.

[0089] In addition, the contract data of the terminal device may also include information such as the network intelligent service type, network intelligent service identification, network intelligent service capabilities and network intelligent service privacy requirements.

[0090] Optionally, the network default provision method is that the terminal device transmits at least one of the network intelligent service type, network intelligent service identifier, network intelligent service capability and network intelligent service privacy requirement, or the network default configuration is that at least one of the network intelligent service type, network intelligent service identifier, network intelligent service capability and network intelligent service privacy requirement.

[0091] For the network default provision method, the terminal device does not need to send a network intelligent service establishment request. The terminal device can transmit information such as the network intelligent service type, network intelligent service identification, network intelligent service capabilities and network intelligent service privacy requirements through a registration request; the network can also configure information such as the network intelligent service type, network intelligent service identification, network intelligent service capabilities and network intelligent service privacy requirements by default. In this case, the terminal device may not transmit this information.

[0092] Specifically, if the terminal device requires network intelligent services when accessing the network, the terminal device adds network intelligent service establishment request parameters in the registration request, and optionally adds parameters such as network intelligent service type, network intelligent service type, network intelligent service identifier, network intelligent service capability, and network intelligent service privacy requirements. After receiving the registration request, the access and mobility management network element confirms the network intelligent service and obtains the contract data from the data management network element, optionally carrying parameters such as network intelligent service authorization information, network intelligent service type, network intelligent service identifier, network intelligent service capability, and network intelligent service privacy requirements; combined with the information provided in the registration request and the information in the network default provision method, confirm the terminal device's need to obtain network intelligent services.

[0093] Step S320: determining the network intelligent service network element according to the service requirements of the network intelligent service based on static configuration or service network element discovery method.

[0094] After confirming the terminal device's need to obtain network intelligent services, the access and mobility management network element can discover network intelligent service network elements from the network through static configuration or service network element discovery according to the service requirements of the network intelligent service.

[0095] Among them, the static configuration method is to configure the access and mobility management network element with the corresponding network intelligent service identifier, fully qualified domain name (FQDN) or IP address, etc. according to the subscription permanent identifier (SUPI) segment of the terminal device.

[0096] The service network element discovery method can be the Network Repository Function (NRF) and Service Communication Proxy (SCP) discovery method, which is a standardized general process. Parameters such as SUPI and Area of ​​Interest (AOI) are passed to NRF or SCP, which returns the identifier, FQDN or IP address of the network intelligent service.

[0097] The embodiments of the present disclosure provide three methods for providing network intelligent services, and the three methods can be combined. The network intelligent service requirements of terminal devices are confirmed through the network intelligent service provision methods, and then suitable network intelligent service network elements are discovered and selected, thereby providing user-exclusive network intelligent services to terminal devices, supporting terminal devices to directly initiate network intelligent services related to them, and improving the user-centric network intelligent service experience.

[0098] In step S220, in the registration and session process, an association is established between the terminal device, the target network element and the network intelligent service network element.

[0102] In the disclosed embodiment, in the registration process, the association between the terminal device, the access and mobility management network element, the terminal policy control network element, the access and mobility management policy control network element and the network intelligent service network element can be established. Also, in the process related to the session such as session establishment or session modification, the association between the session management network element, the session policy control network element, the user plane network element and the network intelligent service network element can be established.

[0103] Optionally, in other processes, associations between terminal devices, other related network elements and network intelligent service network elements may also be established. For example, in processes such as location management and perception management, related network elements such as location management network elements and perception management network elements establish network intelligent service associations with network intelligent service network elements to facilitate the provision of subsequent network intelligent services. The association process is similar to the association process in the session establishment process, and the embodiments of the present disclosure do not limit this.

In addition, the access and mobility management network element sends a request to the network intelligent service network element to obtain network intelligent service information related to access and mobility management.

Then, the network intelligent service network element registers with the data management network element, passing information such as SUPI and network intelligent service identification to indicate that it serves the terminal device.

[0130] For ease of understanding, specific embodiments are listed below to illustrate the establishment of associations in the registration process in the embodiments of the present disclosure.

[0131] Figure 5 A schematic diagram of a process of establishing an association between a terminal device, a target network element and a network intelligent service network element in a registration process according to an embodiment of the present disclosure is shown. Figure 5 The figure shows the process of establishing association between terminal equipment, access and mobility management network element, terminal policy control network element, access and mobility management policy control network element and network intelligent service network element in the registration process, and the process of starting network intelligent service in the registration process. Figure 5As shown, the following steps may be specifically included.

[0132] Step S501: The terminal device sends a registration request to an access and mobility management network element.

[0133] The registration request includes a network intelligent service establishment request, which indicates that the terminal device wishes to obtain the network intelligent service.

[0134] In addition, the registration request also includes information such as network intelligent service type, network intelligent service identifier, network intelligent service capability and network intelligent service privacy requirements. The transmission of this information indicates that the terminal device wishes to obtain specific network intelligent services.

[0135] The network intelligent service type may be specified as a general service, a terminal service, an access service, a mobile service, a session service, a location service, and a perception service, etc. The network intelligent service identifier may be specified as a certain network intelligent service.

[0136] It should be noted that, in addition to carrying a network intelligent service establishment request in a registration request to indicate that it wishes to obtain network intelligent services, the terminal device can also pre-sign a network intelligent service association intention in the data management network element, specifically add the authorization information of the network intelligent service in the contract data of the terminal device, and indicate the desire to obtain the network intelligent service through the authorization information. The contract data of the terminal device may also include information such as the network intelligent service type, network intelligent service identifier, network intelligent service capability, and network intelligent service privacy requirements.

[0137] In addition, network intelligent services can also be obtained through the network default provision method. For the network default provision method, the terminal device does not need to send a network intelligent service establishment request, and the terminal device can transmit information such as the network intelligent service type, network intelligent service identification, network intelligent service capabilities, and network intelligent service privacy requirements through a registration request; the network can also configure the network intelligent service type, network intelligent service identification, network intelligent service capabilities, and network intelligent service privacy requirements by default. In this case, the terminal device does not need to transmit this information.

[0138] Step S502: After receiving the registration request, the access and mobility management network element obtains the subscription data of the terminal device from the data management network element when the terminal device registers.

[0139] As explained in step S501, the terminal device can sign a network intelligent service association intention in advance in the data management network element, so the signing data of the terminal device can include the authorization information of the network intelligent service, and can also include information such as the network intelligent service type, network intelligent service identification, network intelligent service capability and network intelligent service privacy requirements.

[0140] Step S503: The access and mobility management network element selects a network intelligent service, and discovers and selects a network intelligent service network element through static configuration or service network element discovery.

[0141] Specifically, the access and mobility management network element combines the registration request of the terminal device, the contract data of the terminal device and the network default provision method to determine the network intelligent service that the terminal device expects to obtain, and then discovers the network intelligent service network element from the network through static configuration or service network element discovery based on the service requirements of the network service.

[0142] Among them, the static configuration method is to configure the access and mobility management network element with the corresponding network intelligent service identifier, FQDN or IP address according to the SUPI segment of the terminal device. The service network element discovery method can be the NRF and SCP discovery method, which is a standardized general process. SUPI and AOI and other parameters are passed to NRF or SCP, which returns the network intelligent service identifier, FQDN or IP address.

[0143] Step S504: the access and mobility management network element initiates a network intelligent service establishment request to the network intelligent service network element, wherein the network intelligent service establishment request includes information such as network intelligent service type, network intelligent service identifier, network intelligent service capability and network intelligent service privacy requirement.

[0144] In addition, the access and mobility management network element can also subscribe to network intelligent service information related to access and mobility management according to demand, such as user movement trajectory analysis, so the network intelligent service establishment request can also include network intelligent service subscription and related information related to access and mobility management.

[0145] In addition, for the network default provision mode, the access and mobility management network element can transmit information such as the network intelligent service type and the network intelligent service identifier according to the configuration; if this information is also configured by the network default, the access and mobility management network element may not transmit it.

[0146] Step S505: If the access and mobility management network element does not transmit the terminal privacy requirement, the network intelligent service network element may directly obtain it from the data management network element.

[0147] Step S506: The network intelligent service network element returns a network intelligent service establishment response to the access and mobility management network element. The network intelligent service establishment response includes network intelligent service capabilities, data subscription information of the terminal device, data transmission requirements, and address information of the network intelligent service network element.

[0148] Among them, the data subscription information of the terminal device can be terminal resource data, terminal type, and notification conditions, etc.; the data transmission requirements can be user plane requirements, signaling methods, etc.; the address information of the network intelligent service network element is used for direct communication of terminal devices.

[0149] Step S507, when the access and mobility management network element establishes the access and mobility management policy association, it adds a network intelligent service identifier, the address of the network intelligent service network element and other related information to inform the selected network element intelligent service network element.

[0150] Step S508, the access and mobility management policy control network element initiates the establishment of a network intelligent service to the network intelligent service network element, informs its identity, and can subscribe to network intelligent services related to the access and mobility management policy, such as access mode prediction. In addition, the access and mobility management policy control network element can optionally pass on the current policy for subsequent analysis.

[0151] Step S509, the access and mobility management network element sends a registration acceptance to the terminal device, transmitting relevant information of the network intelligent service, specifically transmitting the network intelligent service type, network intelligent service identifier, network intelligent service capability, data subscription information of the terminal device, data transmission requirements and address information of the network intelligent service network element, etc.

[0152] Step S510, the access and mobility management network element establishes terminal policy association with the terminal policy control network element, adds a network intelligent service identifier, the address of the network intelligent service network element and other related information to inform the selected network element intelligent service network element.

[0153] Step S511, the terminal policy control network element initiates network intelligent service establishment to the network intelligent service network element, informs its identity, and can subscribe to network intelligent services related to terminal policies, such as location prediction. In addition, the terminal policy control network element can optionally transfer the current policy for subsequent analysis.

[0154] Step S512, the terminal device sends a registration completion message to the access and mobility management network element, which carries a network intelligent service confirmation and may also indicate confirmation of information such as data subscription and transmission mode.

[0155] Step S513: the access and mobility management network element sends a network intelligent service establishment confirmation and related messages to the network intelligent service network element.

[0156] Step S514, the network intelligent service network element registers with the data management network element, and transmits information such as SUPI and network intelligent service identifier to indicate that it serves the terminal device.

[0157] Step S515: the network intelligent service network element starts the network intelligent service.

[0158] Specifically, the network intelligent service network element can determine to start the network intelligent service based on the network intelligent service subscription information of the terminal device, access and mobility management network element, terminal policy control network element, and access and mobility management policy control network element; or, the network intelligent service network element can autonomously start the default network intelligent service, such as user movement trajectory, access method analysis and other services.

[0159] Step S516, the network intelligent service network element may optionally subscribe to relevant information such as policy changes, etc. from the terminal / access and mobility management policy control network element according to the service requirements of the network intelligent service that needs to be started, or collect data required for other network intelligent service model training or reasoning.

[0160] In step S517, the network intelligent service network element may optionally subscribe to relevant information from the access and mobility management network element, such as terminal location changes, or collect data required for other network intelligent service model training or reasoning.

[0161] Step S518: The network intelligent service network element collects terminal resource capability data from the terminal device.

[0162] Since network intelligent services may use the resources or historical data of terminal devices, network intelligent service network elements can contact terminal devices and collect terminal resource capability data through user plane or signaling, such as terminal type, model, resource capability, current occupancy status, change notification, etc. It can also confirm specific privacy requirements, such as whether federated learning is supported, for subsequent network intelligent services.

[0163] Step S519: the network intelligent service network element collects data from other data sources according to the service requirements of the network intelligent service, wherein other data sources may include network management, base stations, applications involved in the terminal device, network intelligent service data collection and storage network elements, etc.

[0164] Step S520: The network intelligent service network element performs model training or reasoning.

[0165] Specifically, the network intelligent service network element can start or independently start the network intelligent service according to the subscription demand. For example, it can perform terminal behavior trajectory analysis and data network performance analysis of the terminal to model training service to prepare for subsequent network intelligent services; it can determine to collect terminal data for model training or reasoning based on user privacy requirements and capability data and other information; it can jointly perform distributed learning such as federated learning or split reasoning with terminals, network elements, etc.

[0166] Step S521, the network intelligent service network element returns the network intelligent service result to the terminal device, the access and mobility management network element, the terminal policy control network element and the access and mobility management policy control network element. For example, it provides handover preparation, access change preparation, etc. to the access and mobility management network element.

[0167] In step S522, the network intelligent service network element may directly issue relevant policies or policy suggestions, such as access type switching, to the terminal policy control network element and the access and mobility management policy control network element.

[0168] The disclosed embodiments disclose three methods for providing network intelligent services, and the three methods can be combined. The network intelligent service requirements of terminal devices are confirmed through the network intelligent service provision methods, and then suitable network intelligent service network elements are discovered and selected, thereby providing user-exclusive network intelligent services to terminal devices, supporting terminal devices to directly initiate network intelligent services related to them, and improving the user-centric network intelligent service experience.

[0169] Also, in the registration process, an association can be established between the terminal device, the access and mobility management network element, the terminal policy control network element, the access and mobility management policy control network element and the network intelligent service network element, and after the association is established, the access and mobility management network element, the terminal policy control network element and the access and mobility management policy control network element can subscribe to or request relevant information of the network intelligent service from the network intelligent service network element, and receive a notification or response from the network intelligent service network element. In addition, the network intelligent service network element can register with the data management network element to indicate that the network intelligent service network element can provide network intelligent services for the terminal device. In addition, the network intelligent service network element can start the network intelligent service according to the subscription service requirements, or start the network intelligent service autonomously, thereby intelligently improving the user experience.

[0170] In some embodiments of the present disclosure, in a session process, establishing an association among a session management network element, a session policy control network element, a user plane network element and a network intelligent service network element may include: receiving a session request sent by a terminal device; and establishing an association among a session management network element, a session policy control network element, a user plane network element and a network intelligent service network element based on the session request.

[0171] Specifically, the terminal device can initiate a session request based on the data transmission requirements returned by the network intelligent service network element in the registration process, or the terminal device can initiate a session request based on business requirements; then, based on the session request, an association is established between the session management network element, the session policy network element, the user plane network element and the network intelligent service network element.

[0172] The session request may include a session establishment request, a session modification request, and other session-related requests. Furthermore, if the session-type network intelligent service is not requested in the registration process, the session request includes a session-type network intelligent service request; and if the session-type network intelligent service is requested in the registration process, the session request includes a service request corresponding to the new session-type network intelligent service, and the new session-type network intelligent service is a service that has not been requested before.

[0173] If the establishment of a session-based network intelligent service is not requested during the registration process, the session-based network intelligent service can be established through a session request. Specifically, a session-based network intelligent service request is added to the session request.

[0174] If a session-based network intelligent service has been requested during the registration process, a session-based network intelligent service that has not been requested before can be established through the session request, and a new session-based network intelligent service can be established through the session request. Specifically, a new session-based network intelligent service request is added to the session request, and service-related parameter information such as the service type, service identifier, service capability, and service privacy requirements of the new session-based network intelligent service can also be transmitted through the session request.

[0175] Figure 6 The following is a schematic diagram showing the process of establishing associations among a session management network element, a session policy control network element, a user plane network element, and a network intelligent service network element in a session process according to an embodiment of the present disclosure. Figure 6 As shown, the process of establishing an association in a session process may include the following steps.

[0176] Step S610: The session management network element initiates a network intelligent service association with a network intelligent service network element according to the acquired identification-related information of the network intelligent service.

[0177] The information related to the identification of the network intelligent service may include the network intelligent service identification, the address of the network intelligent service network element, and other related information.

[0178] The terminal device initiates a session request to the access and mobility management network element, and then the access and mobility management network element sends a session context establishment request to the session management network element. The session context establishment request carries the network intelligent service identifier, the address of the network intelligent service network element and other relevant information, so that the session management network element can select the same network intelligent service network element.

[0179] The session management NE initiates the establishment of a network intelligent service to the network intelligent service NE, and informs it of session-related information such as identification, data network name information (DNN), and single-network slice selection assistance information (S-NSSAI).

[0180] Step S620: The session policy control network element initiates a network intelligent service association with the network intelligent service network element according to the acquired identification-related information of the network intelligent service.

[0181] When the session management NE initiates association establishment or modification to the session policy control NE, it can provide the network intelligent service identifier, the address of the network intelligent service NE, and other relevant information. The session policy control NE can determine the selected network intelligent service NE based on the information obtained, initiate network intelligent service establishment to the network intelligent service NE, inform it of its identifier, and also pass the current session policy for subsequent analysis.

[0182] Step S630: The user plane network element initiates a network intelligent service association with the network intelligent service network element according to the acquired identification-related information of the network intelligent service.

[0183] If the user plane network element supports direct data reporting and network intelligent service subscription, when the session management network element initiates session establishment or session modification to the user plane network element, such as N4 session establishment, it transmits the network intelligent service identifier, the address of the network intelligent service network element, and other related information. The user plane network element determines the selected network intelligent service network element based on the information obtained, initiates network intelligent service establishment to the network intelligent service network element, informs its identifier, and can subscribe to user plane related network intelligent services, such as user plane path performance analysis, for subsequent analysis.

In addition, the session management network element may send a request to the network intelligent service network element to obtain network intelligent service information related to session management.

[0186] When the session policy control network element initiates the establishment of a network intelligent service to inform the network intelligent service network element of its identity, it can subscribe to network intelligent services related to the session policy, such as service experience analysis, etc. In addition, the session policy control network element sends a request to the network intelligent service network element to obtain network intelligent service information related to the session policy.

Specifically, it can subscribe to or request network intelligent service information related to session management, such as user communication behavior, etc. from the session management network element; subscribe to or request network intelligent service information related to session policy, such as service experience analysis, etc. from the session policy control network element; and subscribe to or request network intelligent service information related to the user plane, such as user plane path performance analysis, etc. from the user plane network element.

[0193] For ease of understanding, specific embodiments are listed below to illustrate the association establishment in the session establishment process in the embodiments of the present disclosure.

[0194] Figure 7 A schematic diagram of a process of establishing association between a terminal device, a target network element and a network intelligent service network element in a session establishment process according to an embodiment of the present disclosure is shown. Figure 7 The embodiment shows the process of establishing association between the terminal device, the session management network element, the session policy control network element, the user plane network element and the network intelligent service network element in the session establishment process, and the process of starting the network intelligent service in the session establishment process. Figure 7 As shown, the following steps may be specifically included.

[0195] Step S701: The terminal device sends a session establishment request to an access and mobility management network element.

[0196] Specifically, the terminal device may initiate a session establishment request according to the data transmission requirement returned by the network intelligent service network element in the registration process; or, the terminal device may initiate a session establishment request according to business requirements.

[0197] If the establishment of a session-type network intelligent service is not requested during the registration process, a session-type network intelligent service can be established through a session establishment request. Specifically, a new session-type network intelligent service request is added to the session establishment request. If the establishment of a session-type network intelligent service is requested during the registration process, a session-type network intelligent service that has not been requested before can be established through the session establishment request, that is, a new session-type network intelligent service can be established through the session establishment request. Specifically, a new session-type network intelligent service request is added to the session establishment request, or service type, service identifier, service capability, service privacy requirements and other service-related parameter information of the new session-type network intelligent service are transmitted through the session establishment request.

[0198] Step S702: The access and mobility management network element determines whether a session-type network intelligent service association needs to be established based on information such as the network intelligent service type provided during registration.

[0199] Step S703: If the access and mobility management network element determines that a session-type network intelligent service association needs to be established, the access and mobility management network element sends a session context establishment request to the session management network element.

[0200] The session context establishment request is added with a network intelligent service identifier, an address of a network intelligent service network element, and other related information, so that the session management network element can select the same network intelligent service network element.

[0201] Step S704, the session management NE initiates the establishment of a network intelligent service to the network intelligent service NE, and informs it of session related information such as identity, DNN, S-NSSAI, etc. In addition, the session management NE can subscribe to session related network intelligent services according to demand, such as user communication behavior, and provide related information.

[0202] Step S705, when the session management network element establishes the session policy association, it adds the network intelligent service identifier, the address of the network intelligent service network element and other related information to inform the selected network element intelligent service network element.

[0203] Step S706, the session policy control network element initiates network intelligent service establishment to the network intelligent service network element, informs its identity, and can subscribe to network intelligent services related to the session policy, and can also transfer the current session policy for subsequent analysis.

[0204] Step S707, if the user plane network element supports direct data reporting and network intelligent service subscription, when the session management network element establishes an N4 session with the user plane network element, it adds a network intelligent service identifier, the address of the network intelligent service network element and other relevant information to inform the selected network element intelligent service network element.

[0205] Step S708, the user plane network element initiates network intelligent service establishment to the network intelligent service network element, informs its identity, and can subscribe to user plane related network intelligent services, such as user plane path performance analysis, for subsequent analysis.

[0206] Step S709: The network intelligent service network element starts the session-based network intelligent service.

[0207] Specifically, the network intelligent service network element can determine to start the session-type network intelligent service based on the network intelligent service subscription information of the terminal device, session management network element, session policy control network element and user plane network element; the network intelligent service network element can also autonomously start the default session-type network intelligent service, such as routing policy, QoS policy and other services.

[0208] Step S710, the network intelligent service network element may optionally subscribe to relevant information, such as policy changes, from the session policy control network element according to the determined service requirements of the session network intelligent service, or collect data required for other network intelligent service model training or reasoning.

[0209] Step S711, the network intelligent service network element may optionally subscribe to relevant information from the session management network element, such as session release establishment, etc., or collect data required for other network intelligent service model training or reasoning.

[0210] Step S712, the network intelligent service network element may optionally subscribe to relevant information from the user plane network element, such as user plane latency, or collect data required for other network intelligent service model training or reasoning.

[0211] Step S713: The network intelligent service network element collects terminal resource capability data from the terminal device.

[0212] Since network intelligent services may use the resources or historical data of terminal devices, network intelligent service network elements can contact terminal devices and collect terminal resource capability data through user plane or signaling, such as terminal type, model, resource capability, current occupancy status, change notification, etc. It can also confirm specific privacy requirements, such as whether federated learning is supported, for subsequent network intelligent services.

[0213] Step S714: The network intelligent service network element collects data from other data sources according to the service requirements of the session network intelligent service, wherein other data sources may include network management, base stations, applications involved in the terminal device, network intelligent service data collection and storage network elements, etc.

[0214] Step S715: The network intelligent service network element performs model training or reasoning.

[0215] Specifically, the network intelligent service network element can start or autonomously start session-type network intelligent services based on subscription needs. For example, it can perform data network performance analysis from terminal devices to model training services to prepare for subsequent network intelligent services. It can determine to collect terminal data for model training or reasoning based on user privacy requirements and capability data and other information. It can also jointly perform distributed learning such as federated learning or split reasoning with terminals, network elements, etc.

[0216] Step S716: The network intelligent service network element returns the session-related network intelligent service result to the session management network element, the session policy control network element, and the terminal device, for example, providing the communication characteristics of the terminal device to the session management network element.

[0217] In step S717, the network intelligent service network element may directly send session-related policies or policy recommendations, such as routing policies, QoS policies, etc., to the session policy control network element.

[0218] It should be noted that Figure 7 The embodiment shows the process of establishing association and starting network intelligent service in the process of session establishment. In other processes related to the session, such as session modification, the association between the session management network element, the session policy control network element, the user plane network element and the network intelligent service network element can also be established, and the association process is similar to the association process in the process of session establishment.

[0219] In the session process, the association between the session management network element, the session policy control network element, the user plane network element and the network intelligent service network element can be established, and after the association is established, the session management network element, the session policy control network element and the user plane network element can subscribe to or request the relevant information of the session network intelligent service from the network intelligent service network element, and receive the notification or response of the network intelligent service network element. In addition, the network intelligent service network element can start the session network intelligent service according to the subscription service requirements, or start the session network intelligent service autonomously, so as to intelligently improve the user experience.

[0220] In addition, in other processes, associations between terminal devices, other related network elements and network intelligent service network elements may also be established. For example, in processes such as location management and perception management, related network elements such as location management network elements and perception management network elements establish network intelligent service associations with network intelligent service network elements to facilitate the provision of subsequent network intelligent services. The association process is similar to the association process in the session establishment process, and the embodiments of the present disclosure do not limit this.

[0221] In step S230, based on the established association, a network intelligent service is provided to the terminal device through a network intelligent service network element.

[0222] In some embodiments of the present disclosure, based on the established association, network intelligent services are provided to terminal devices through network intelligent service network elements, which may include: based on the established association, the terminal device or the target network element subscribes to or requests network intelligent services from the network intelligent service network element, so that the network intelligent service network element collects data, performs model training and inference processing on the terminal device, the target network element and the target data source to obtain the service results of the network intelligent service; and obtains the service results of the network intelligent service sent by the network intelligent service network element.

[0223] Based on the association between the terminal device, the target network element and the network intelligent service network element, the terminal device and the target network element can send a network intelligent service request to the network intelligent service network element. After receiving the service request, the network intelligent service network element can collect data, train and infer the network intelligent service model to obtain the service result, and then the network intelligent service network element sends the service result to the terminal device and the target network element. In addition, the service result may include policies and policy recommendations, and the network intelligent service network element can send the policies and policy recommendations to the session / terminal / access and mobility management policy control network element.

[0224] Figure 8 A flow chart of providing a network intelligent service for a terminal device through a network intelligent service network element based on an established association according to an embodiment of the present disclosure is shown. Figure 8 The figure shows that after the association is established, service consumers such as terminal devices and network elements can request network intelligent services from the network intelligent service network element, and the process diagram of the network intelligent service network element providing network intelligent services. Figure 8 As shown, the following steps may be specifically included.

[0225] Step S801: Based on the established association, when the terminal device, each network element and other consumers need to subscribe to the network intelligent service, they initiate a subscription request to the network intelligent service network element.

[0226] Among them, terminal devices and network elements can directly initiate subscription requests to the network intelligent service network element. Other consumers can discover the network intelligent service network element that provides network intelligent services through the data management network element and initiate subscription requests to the network intelligent service network element.

[0227] Step S802: The network intelligent service network element determines the network intelligent service mode based on the subscription request, combined with the previously acquired user privacy, terminal resource capability data, previously performed movement trajectory, DN performance and other data. For example, it can be determined to collect terminal data for model training or reasoning, or to combine terminal devices, network elements, etc. for federated learning, distributed learning or split reasoning, etc., based on user privacy requirements and capability data and other information.

[0228] Step S803: The network intelligent service network element initiates data collection or collaborative training or reasoning tasks for terminal devices, network elements, other consumers, and other data sources.

[0229] Step S804: The network intelligent service network element performs model training or reasoning related to the network intelligent service.

[0230] Step S805: The network intelligent service network element returns the network intelligent service result to the terminal device, each network element, and other consumers, and issues a policy or policy suggestion to the terminal / access and mobility management / session management policy control network element.

[0231] The communication method of the embodiment of the present disclosure can obtain information such as resource capabilities and network performance of the terminal device in advance based on the established association, which is convenient for the training of network intelligent services and the selection of reasoning methods. It can also collect necessary data and start autonomous network intelligent services in advance based on the established association, thereby improving the accuracy and efficiency of network intelligent services.

[0232] Fig. 9 A flow chart of another communication method in an embodiment of the present disclosure is shown. Fig. 9 The communication method shown in the embodiment can be applied to a terminal device, and specifically includes steps S910 to S920.

[0233] Step S910, accessing the network through the core network element to perform registration and session process, so that the core network element determines the network intelligent service element that provides network intelligent service to the terminal device when the terminal device accesses the network, and establishes the association between the terminal device, the target network element and the network intelligent service network element during the registration and session process.

[0234] Among them, the target network elements may include various related network elements, for example, network elements related to access management, mobility management, session management, policy control, location management, perception management, etc. The target network elements may also include network elements that communicate with other domains, for example, capability exposure network elements, etc.

[0235] Step S920: Based on the established association, obtain the network intelligent service provided by the network intelligent service network element.

[0236] When a terminal device accesses the network through a core network element, the core network element can determine the network intelligent service element that provides the terminal device with network intelligent services, and then establish an association between the terminal device, the target network element and the determined network intelligent service element in the registration and session processes, and then enable the network intelligent service based on the established association. The above has detailed descriptions of the process of determining the network intelligent service element, the process of establishing the association between the terminal device, the target network element and the network intelligent service element in the registration and session processes, and the process of enabling the network intelligent service, which will not be repeated here.
