In order to facilitate the understanding of the technical solutions of the embodiments of the present application, the technical solutions related to the embodiments of the present application are described below.

With the artificial intelligence of the network, artificial intelligence (Artifact Intelligence, AI)/Machine Learning (ML) will participate in the mobile network. For this reason, a mechanism is needed to realize the big data analysis model between the terminal and the network. (It can also be called a network model, or a model for short) negotiation, so as to realize the guarantee of the communication network for big data analysis.

AI/ML (that is, big data analysis) is the direction of future network development and can be used for the optimization of communication systems, such as the optimization of terminal configuration parameters, the optimization of Policy Control and Charging (PCC), and the quality of service ( Quality of Service, QoS) parameter optimization, etc. In order to achieve this goal, communication networks (such as mobile communication networks) need to introduce big data analysis-related functions and network elements, such as Network Data Analysis Function (NWDAF) network elements for collection, analysis and formation of value Parameter optimization method.

For big data analysis models, there can be Deep Neural Network (DNN) model, Recurrent Neural Network (RNN) model, Convolution Neural Network (CNN) model, Multilayer Perception (Multilayer) Perception, MPL) model, etc. The most widely used model is the DNN model. As shown in Figure 2-1, the DNN model is divided according to the location of different layers. The neural network layer inside the DNN model can be divided into three categories: input layer, hidden layer and output layer. Generally speaking, the first layer of the DNN model is the input layer, the last layer of the DNN model is the output layer, and the number of layers in the middle of the DNN model are all hidden layers.

The input layer needs to use specific algorithms, weight coefficients, constants, etc. to calculate the sample parameters of the input layer to obtain the output result, which is used as the input of the next layer to calculate the result of the lower layer, and finally get the result of the output layer. As shown in Figure 2-2,

For the output of the second layer

Have:

For the output of the third layer

Have:

Generalizing the above example, assuming that there are m neurons in the l-1th layer, the output of the jth neuron in the lth layer is

Have:

The key to the DNN model is to train the weight coefficients of each layer, and the DNN model is trained through a large number of collected samples (the parameters of the input layer and the results of the output layer) (such as forward propagation and back propagation calculations to continuously iterate out The new weight coefficient), and finally a more ideal weight coefficient can be obtained. In this way, after any subsequent input values, the estimated output value can be obtained through the DNN model.

In order to improve the effect and user experience of big data analysis, a multi-level AI/ML approach can be considered, that is, the network side and the terminal division of labor for big data analysis.

As shown in Figure 3-1, (a) is a centralized scenario, that is, after all terminals report the required data, the big data analysis work is all performed on the network side. (b) is a completely distributed scenario, that is, different terminals analyze the collected data locally. (c) is a hybrid scenario, that is, after the terminal performs a part of the local analysis on the collected data, the result is sent to the network side, and the network side performs further calculation and analysis. In addition, the methods (b) and (c) may also introduce data interaction between the terminal and the terminal to complete big data analysis or result sharing.

For example, as shown in Figure 3-2, big data analysis can be performed on the terminal, edge server, and cloud server, or it can be performed on only one or two of the three. Therefore, the terminal may allocate different network models and calculation workloads as required, and the calculation is completed within the required time and is successfully sent to the network side.

Because different terminals have different requirements for big data analysis in different scenarios (for example, different network models are required, the amount of calculation is different, and the required time for transmission to the network is different). Therefore, the network side needs to negotiate the use of different network models according to different terminals and requirements, and allocate different data stream related parameters (such as QoS parameters) according to the work requirements of different terminals to ensure reasonable and timely big data analysis results It can be transmitted between the terminal and the network side. To this end, the following technical solutions of the embodiments of the present application are proposed. It should be noted that the model in the embodiment of the present application refers to a network model, and may also be referred to as an AI/ML model.

Based on this, each model identifier can correspond to a network identifier (such as PLMN ID, or NPN ID, or SP ID) to distinguish that the model identifier is allocated (that is, determined) by a specific network. Further, each model identifier may be globally unique or not (for example, unique under a specific network). In addition, the network identifier can also limit the terminal to use or report the corresponding model identifier under a specific network. The following introduces several examples of optional model information. The following example takes the model information including the model identifier and the network identifier as an example.

The AS layer is read by an access network element (such as a base station), and the NAS layer is directly forwarded by an access network element (such as a base station) to a core network element. . Further, the information carried in the AS layer is used for the access network element to determine the core network element, and to send the NAS message to the core network element.

In an example, the first model information is carried in the NAS layer of the NAS message. After receiving the NAS message, the access network element directly forwards the NAS message to the core network element.

In another example, a part of the first model information is carried in the AS layer of the NAS message, and the other part is carried in the NAS layer of the NAS message. After receiving the NAS message, the access network element reads the AS layer of the NAS message, determines the corresponding core network element according to the AS layer information, and forwards the NAS message to the corresponding core network Network element.

Here, optionally, the core network element is AMF.

In another example, the second model information is determined by the service server. Specifically, after the core network element receives the NAS message sent by the terminal, it obtains the first model information from the NAS message, forwards the first model information to the service server, and the service server determines which of the first model information is The model information allows new model information (that is, the second model information) to be used or allocated to the terminal, and is sent to the core network element. Here, optionally, the core network element is AMF. The service server is an SP server or an edge server.

In the above solution, the second model information is the same as at least part of the model information in the first model information, that is, the second model information is the core network element or the service server from the first model information Determine the allowed model information. Alternatively, the second model information is different from the first model information, that is, the second model information is model information newly allocated to the terminal by the core network element or the service server.

For example, the terminal obtains the IP address of the service server according to the resource information of the download model, and initiates a download request to the service server, and the service server can send the content of the model to the terminal through the user interface. Or, the service server directly sends the content of the model to the terminal without a request from the terminal. The service server may be a core network network element, an access network network element, or an edge computing server.

It should be noted that since the model identifier in the second model information can identify a complete model or a part of a model, the model content downloaded by the terminal from the service server can be the complete content of a model or a model. Part of the content.
