[0044] Example embodiments will now be described more fully with reference to the accompanying drawings. However, example embodiments can be implemented in a variety of forms and should not be construed as limited to the examples set forth herein; rather, these embodiments are provided so that the disclosure will be more comprehensive and complete and to fully convey the concepts of the example embodiments to those skilled in the art. The described features, structures, or characteristics may be combined in any suitable manner in one or more embodiments.

[0045] 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.

[0046] The specific implementation of the embodiment of the present disclosure is described in detail below with reference to the accompanying drawings.

[0047] Figure 1 A schematic diagram of an exemplary application system architecture to which the network service acquisition method in the embodiments of the present disclosure can be applied is shown.

[0048] like Figure 1 As shown, the system architecture includes a terminal device 101, a network 102 and a network-side device 103; the network 102 is used to provide a medium for a communication link between the terminal device 101 and the network-side device 103, and can be a wired network or a wireless network.

[0049] Optionally, the wireless network or wired network described above uses standard communication technology and / or protocol. The network is typically the Internet, but may also be any network, including but not limited to a local area network (LAN), a metropolitan area network (MAN), a wide area network (WAN), a mobile, wired or wireless network, a dedicated network or any combination of a virtual private network. In some embodiments, the data exchanged through the network is represented using technology and / or formats including Hyper Text Mark-up Language (HTML), Extensible Markup Language (XML), etc. In addition, conventional encryption technologies such as Secure Socket Layer (SSL), Transport Layer Security (TLS), Virtual Private Network (VPN), Internet Protocol Security (IPsec) may be used to encrypt all or some links. In other embodiments, customized and / or dedicated data communication technologies may also be used to replace or supplement the above data communication technologies.

[0050] Optionally, the terminal device 101 in the embodiment of the present disclosure may also be referred to as UE (User Equipment). In a specific implementation, the terminal device 101 may be a terminal-side device such as a mobile phone, a tablet computer (Tablet Personal Computer), a laptop computer (Laptop Computer), a personal digital assistant (Personal Digital Assistant, PDA), a mobile Internet device (Mobile Internet Device, MID), a wearable device (Wearable Device) or a vehicle-mounted device.

[0051] 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.

[0052] The network side device 103 includes various network entities of the access network or core network, including but not limited to access and mobility management function (Access and Mobility Management Function, AMF) network element, session management function (Session Management Function, SMF) network element, unified data management (Unified Data Management, UDM) network element, user plane function (User Plane Function, UPF) network element and policy control function (Policy Control Function, PCF) network element, etc. It should be noted that the specific type of network side equipment is not limited in the embodiment of the present disclosure.

[0053] like Figure 1 As shown in the figure, the AMF network element supports UEs with different mobility management requirements. The PCF network element interacts with the access and mobility policy implementation in the AMF network element through the service-based interfaces (SBI); the UDM network element is part of the 5G core network control plane and is the front-end architecture of the 5G user database. The UDM network element is the user subscription data management part of the control plane, responsible for processing business logic, responsible for signaling processing with other core network elements, and saves dynamic data of users and services; the UE sends a subscription data request to the UDM network element through the AMF network element for user registration; the SMF network element is used to establish a session and configure the flow control of the UPF network element to route the traffic to the correct destination. As a user-plane network element of the 5G network, the UPF network element mainly supports the routing and forwarding of UE service data, data and service identification, action and policy execution, etc. The UPF network element interacts with the SMF network element through the N4 interface, is controlled and managed by the SMF network element, and executes service flow processing according to various policies issued by the SMF network element. In other words, after the SMF network element receives the session policy control creation response from the PCF network element, it controls the UPF network element to execute service flow processing.

[0054] Those skilled in the art will know that Figure 1 The number of terminal devices, networks, and network-side devices in the example is merely illustrative, and any number of terminal devices, networks, and network-side devices may be provided according to actual needs. The embodiments of the present disclosure do not limit this.

[0055] In the 3GPP specification, consumers who request artificial intelligence (AI) services only include network elements, OAM, and application layers within the network, and do not support terminal devices requesting AI services. However, terminal devices have the need to obtain network AI services. For example, due to limited resources, they can use the network to assist in reasoning analysis or model training; obtain network status and other information through the network for terminal device access mode selection, etc.

[0056] In the related technologies, the transmission of terminal data in the 3GPP specification is transferred through the application layer, which places more requirements on the application server and requires the network element function (NEF) to map the external IP address to the internal terminal device ID, etc., which lacks timeliness and flexibility.

[0057] Figure 2 A schematic diagram showing an exemplary architecture of another network service acquisition method provided by an embodiment of the present disclosure. Figure 2 As shown, the system architecture of the present disclosure includes:

[0058] The terminal device 101, as a consumer of the network AI service, uses the AI ​​service provided by the network and provides data required for the AI ​​service, etc.;

[0059] The access management network element 1031, such as the AMF network element in 5G, performs NAS transmission with the terminal device 101, and forwards AI service-related messages to the network intelligent network element 1032 and the terminal device 101;

[0060] The network intelligent network element 1032 provides AI services to the terminal device 101, the application layer, OAM, other network elements, etc. in the network, and supports AI service message transmission between the terminal device 101;

[0061] The application layer provides application-related data for AI model training or model reasoning, etc.

[0062] Core network elements such as SMF network elements, PCF network elements, OAM, and data sources in the network are used for AI model training or model inference, etc.

[0063] The communication process between each node includes: the terminal device 101 adds AI service-related information in the NAS message to support the network intelligent network element 1032 to receive AI service requests from the terminal, collect data or perform model training, model reasoning and other information interactions required for the service to the terminal device 101, and return the service results to the terminal device 101.

[0064] In one application scenario, NAS message transmission is performed directly between the terminal device 101 and the network intelligent network element 1032. The terminal device 101 sends a service request to the network intelligent network element 1032 via a first uplink non-access stratum (NAS) message, and the network intelligent network element 1032 sends a first service result to the terminal device 101 via a first downlink NAS message.

[0065] In an application scenario, the NAS message between the terminal device 101 and the network intelligent network element 1032 is forwarded by the network access node to perform information interaction.

[0066] For example, the access management network element 1031 serves as a network access node, and is used to forward NAS messages between the network intelligent network element 1032 and the terminal device 101 to perform information interaction.

[0067] In addition to using the access management network element 1031, information interaction between the network intelligent network element 1032 and the terminal device 101 can also be achieved through other core network network elements or other services, which is not specifically limited in the present disclosure.

[0068] The following description is made by taking the forwarding of NAS messages between the terminal device 101 and the network intelligent network element 1032 by the network access node as an example.

[0069] The detailed process is as follows:

[0070] The terminal device 101 sends a first uplink NAS transmission to the access management network element 1031. The first uplink NAS transmission carries a service request, and the service request includes at least one of a service request type, a service requirement, and service-related information. The service request type includes AI training, AI reasoning, network status data, and a policy required by the UE.

[0071] The access management network element 1031 forwards the service request to the network intelligent network element 1032 .

[0072] The network intelligent network element 1032 collects service data from the node of the service data required by the service in the service request, such as Figure 2 As shown, the node collecting service data may include at least one of a terminal device, an application layer, a core network element (eg, an SMF network element, a PCF network element, etc.), and an OAM.

[0073] When the access management network element 1031 receives the terminal service request sent by the network intelligent network element 1032, the access management network element 1031 sends a second downlink NAS message to the terminal device. The second downlink NAS message carries the terminal service request. The terminal service request may include a terminal data request, a terminal training request or a terminal reasoning request, which is used to instruct the terminal device 101 to perform data collection, model training or model reasoning, etc.

[0074] The terminal device 101 generates a terminal service result according to the terminal service request, and transmits the terminal service result via the second uplink NAS. The access management network element 1031 forwards the data response or notification sent by the terminal device 101.

[0075] The network intelligent network element 1032 performs data processing, such as model training or model reasoning, based on the service data collected from each node.

[0076] The network intelligent network element 1032 performs corresponding model training or model inference according to the service request of the terminal device 101 to generate a first service result, which includes at least one of the training result, inference result, network status data or UE strategy.

[0077] The network intelligent network element 1032 forwards the first service result to the terminal device 101 through the access management network element 1031 .

[0078] When the service request sent by the terminal device 101 does not carry terminal data or the terminal data is incomplete, the terminal service request includes a terminal data request. The terminal device 101 collects the corresponding terminal data based on the terminal data request and sends the terminal data to the access management network element 1031 through a second uplink NAS message. The access management network element 1031 forwards the terminal data to the network intelligent network element 1032 through a service response or notification.

[0079] If the network intelligent network element 1032 may adopt distributed learning or collaborative reasoning, it sends a terminal training or reasoning request to the access management network element 1031.

[0080] The access management network element 1031 forwards the terminal training or reasoning request to the terminal device 101 to instruct the terminal device 101 to perform model training or model reasoning to obtain a terminal training result or a terminal reasoning result.

[0081] After the terminal device 101 performs model training or reasoning, it sends the terminal training result or the terminal reasoning result to the access management network element 1031 via the second uplink NAS transmission, and the access management network element 1031 sends the above terminal training result or the terminal reasoning result to the network intelligent network element 1032.

[0082] It should be noted that the network elements such as the above-mentioned network intelligent network element 1032 can be a physical entity, a module embedded in other network elements, or a service with specific logic.

[0083] The solution provided by the embodiment of the present disclosure is that the terminal device sends a first uplink NAS message to the network intelligent network element, and the first uplink NAS message carries a service request; receives a first downlink NAS message sent by the network intelligent network element, and the first downlink NAS message carries a first service result, and the first service result is generated by the network intelligent network element according to the service request. The terminal device can obtain network AI services, and by adding AI service related information to the NAS message, the network intelligent network element is supported to receive AI service requests from the terminal device and return service results, and the terminal device is supported to request or subscribe to AI services through the signaling plane, and the network artificial intelligence network element and the terminal device are supported to directly transmit terminal device related data through the signaling plane, so as to improve data acquisition efficiency and flexibility. It is specifically described through the following embodiments:

[0084] The disclosed embodiment provides a method for obtaining network services, which can be executed by any system with computing processing capabilities. In a feasible implementation, the process corresponding to the method can be executed by a terminal device; in another feasible implementation, the process corresponding to the method can be executed by a network intelligent network element; in other feasible implementations, the process corresponding to the method can also be implemented by the interaction between the terminal device and the network intelligent network element.

[0085] Figure 3 A flow chart of a method for obtaining network services in an embodiment of the present disclosure is shown as follows: Figure 3 As shown, the network service acquisition method provided in the embodiment of the present disclosure is applied to a terminal device and includes the following steps:

[0086] S302: Send a first uplink NAS message to the network intelligent network element, where the first uplink NAS message carries a service request.

[0087] Network intelligent network elements, also known as AI service network elements, are network elements that provide AI services to terminal devices, application layers, OAM or other network elements in the network, and support NAS message transmission between terminal devices.

[0088] The service request is used to transmit relevant information of the AI ​​service request to the network intelligent network element to instruct the network intelligent network element to collect data and perform data processing according to the service request.

[0094] Exemplarily, the application layer related information required for data collection may include: application layer address, collection content, such as quality of service (QoS) indicators required by the application layer, current experience, etc.

[0095] A service request may include a service request type and the service requirements and service related information corresponding to the service request type, or may include multiple service request types and the service requirements and service related information corresponding to each service request type, which is not specifically limited in this disclosure.

[0096] S304: Receive a first downlink NAS message sent by the network intelligent network element, where the first downlink NAS message carries a first service result, and the first service result is generated by the network intelligent network element according to the service request.

[0097] The network intelligent network element may also generate a first service result according to the service request. The above processing adopts different processing methods according to different types of service requests.

[0098] It should be noted that the first service result includes at least one of a model training result, an inference result, network status data, a terminal policy, a model parameter, and a terminal inference result. The first service result depends on the service request type in the service request. Among them, the model training result may include an AI model obtained by model training by a network intelligent network element and model parameters obtained by training during the model training process. The model inference result may include a model inference result obtained by model inference by a network intelligent network element. The specific type of the AI ​​model and the results of model training or model inference may be determined according to actual conditions, and this disclosure does not make specific limitations.

[0099] The network status data may specifically include the network status of each data collection node. The terminal strategy may specifically include load balancing strategy, network energy saving strategy, mobility management strategy, etc.

[0100] Specifically, the terminal device sends a first uplink NAS message carrying a service request to the network intelligent network element, such as a ULNAS TRANSPORT message, where the UL NAS TRANSPORT message carries a MO-AI request or subscription to instruct the network intelligent network element to collect or process data and generate a first service result; the network intelligent network element sends a first downlink NAS message to the terminal device, such as a DL NAS TRANSPORT message, where the DL NAS TRANSPORT message carries a MO_AI notification or response.

[0101] It should be noted that for AI services related to terminal devices, the embedded network intelligent network elements or the network intelligent network elements in the area where the terminal devices are located can be preferred.

[0102] In the disclosed embodiment, the terminal device sends a first uplink non-access layer NAS message to the network intelligent network element, and the first uplink NAS message carries a service request; receives a first downlink NAS message sent by the network intelligent network element, and the first downlink NAS message carries a first service result, and the first service result is generated by the network intelligent network element according to the service request. The terminal device can obtain network AI services, and by adding AI service-related information to the NAS message, the network intelligent network element is supported to receive AI service requests from the terminal device and return the first service result, and the terminal device is supported to request or subscribe to AI services through the signaling plane, and the network artificial intelligence network element and the terminal device are supported to directly transmit terminal device related data through the signaling plane, thereby improving data acquisition efficiency and flexibility.

[0103] Figure 4 FIG. 2 shows another flow chart of a method for acquiring network services provided by an embodiment of the present disclosure. Figure 4 As shown, in one embodiment, before receiving the first downlink NAS message sent by the network intelligent network element at S304, the method further includes:

[0104] S402, receiving a second downlink NAS message sent by the network intelligent network element, where the second downlink NAS message carries a terminal service request;

[0105] S404, generating a second service result according to the terminal service request;

[0106] S406: Send the second service result to the network intelligent network element.

[0107] Terminal service requests are tasks that terminal devices need to perform to assist network intelligent elements in data collection, model training, and model reasoning. The frequency or threshold of data reporting can be indicated as needed.

[0108] In one embodiment, the terminal service request includes at least one of a terminal data request, a terminal training request, and a terminal reasoning request. Accordingly, the second service result may include terminal data corresponding to the terminal data request, a terminal training result corresponding to the terminal training request, and a terminal reasoning result corresponding to the terminal reasoning request. It should be noted that the second service result may be determined according to the type of the terminal service request.

[0109] It should be noted that the terminal training request and the terminal reasoning request may also include input data required by the terminal device for model training or model reasoning.

[0110] Among them, the terminal data request is used to instruct the terminal device to collect terminal data and send the collected terminal data to the network intelligent network element. The terminal training request is used to instruct the terminal device to perform AI model training, obtain terminal training results, and report the terminal training results to the network intelligent network element. The terminal reasoning request is used to instruct the terminal device to perform AI model reasoning, obtain terminal reasoning results, and report the terminal reasoning results to the network intelligent network element.

[0111] Exemplarily, if the terminal device does not transmit terminal data or the terminal data is insufficient when sending a service request, the network intelligent network element can collect terminal data from the terminal device again. The second downlink NAS message received by the terminal device carries the terminal data request. The terminal device collects data according to the terminal data request and sends the collected terminal data to the network intelligent network element. After receiving the terminal data, the network intelligent network element can perform corresponding model training or reasoning and other data processing processes according to the service request, and then generate a first service result.

[0112] Exemplarily, the network intelligent network element may adopt distributed learning or collaborative reasoning.

After receiving the terminal training results or terminal reasoning results, the network intelligent network element generates a first service result.

[0113] It should be noted that for federated learning, etc., multiple transmissions can be performed.

[0114] In one embodiment, the second service result may be sent to the network intelligent network element via a second uplink NAS message or a user plane.

[0115] The transmission method of the second service result can be indicated in the terminal training request or the terminal reasoning request.

[0116] The terminal device can also determine the transmission mode according to the data volume of the transmitted model parameters or the terminal inference results. For example, when the above data volume is greater than or equal to the preset data volume threshold, it is transmitted in user plane mode; when the above data volume is less than the preset data volume threshold, it is transmitted in a second uplink NAS message.

[0117] In the embodiments of the present disclosure, the access management network element is supported to send terminal service requests to the terminal device via the signaling plane, and the network intelligent network element and the terminal device are supported to directly transmit terminal device related data via the signaling plane, thereby improving the data acquisition efficiency and flexibility.
