In order to facilitate 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 (AI)/Machine Learning (ML) will participate in the mobile network, and for this reason, a mechanism is needed to implement negotiation between the terminal and the network for a big data analysis model (which may also be referred to as a network model, or simply a model) so as to implement the guarantee of the communication network for big data analysis.
AI/ML (i.e. big data analytics) is a direction of future network development, and may be used for optimization of communication systems, such as optimization of terminal configuration parameters, optimization of Policy Control and Charging (PCC), optimization of Quality of Service (QoS) parameters, and the like. To achieve the purpose, a communication Network (e.g., a mobile communication Network) needs to introduce functions and Network elements related to big Data Analysis, such as Network Data Analysis Function (NWDAF) Network elements for collecting, analyzing and forming a valuable parameter optimization method.
For the big data analysis model, there may be a Deep Neural Network (DNN) model, a Recurrent Neural Network (RNN) model, a Convolutional Neural Network (CNN) model, a Multilayer Perception (MPL) model, and the like. One of the most widely used models is the DNN model, which is divided by the positions of different layers as shown in fig. 2-1, and the neural network layers inside the DNN model can be divided into three categories: an input layer, a hidden layer and an output layer. In general, the first layer of the DNN model is the input layer, the last layer of the DNN model is the output layer, and the middle layers of the DNN model are all hidden layers.
The input layer needs to use a specific algorithm, a weight coefficient, a constant and the like to calculate the sample parameters of the input layer to obtain an output result, and the output result is used as the input of the next layer so as to calculate the result of the next layer and finally obtain the result of the output layer. As shown in the figures 2-2 of the drawings,
for the output of the second layer
Comprises the following steps:
for the output of the third layer
Comprises the following steps:
generalizing the above example, assuming there are m neurons in total at level l-1, the output for the jth neuron at level l
Comprises the following steps:
the key of the DNN model is to train the weight coefficient of each layer, and train the DNN model through a large number of collected samples (parameters of input layers and results of output layers) (e.g., forward propagation and backward propagation calculations to iterate new weight coefficients continuously), so as to obtain a more ideal weight coefficient finally. Thus, after any input value is available, the estimated output value can be obtained through the DNN model.
In order to improve the effect of big data analysis and user experience, a multi-level AI/ML mode may be considered, that is, the network side and the terminal perform big data analysis in a labor division manner.
As shown in fig. 3-1, (a) is a centralized scenario, that is, after all terminals report the required data, the big data analysis is performed on the network side. (b) In a completely distributed scenario, different terminals analyze the acquired data locally. (c) The method is a hybrid scenario, namely, after the terminal locally analyzes part of acquired data, the result is sent to the network side, and the network side performs further calculation and analysis. In addition, in the modes (b) and (c), data interaction between the terminals can be introduced to complete big data analysis or result sharing.
For example, as shown in fig. 3-2, the big data analysis may be performed on the terminal, the edge server, and the cloud server, or may be performed on only one or two of the three. Therefore, the terminal may share different network models and computational workload as required, and perform computation in a required time and successfully send the computation to the network side.
The big data analysis work requirements of different terminals under different scenes are different (for example, different network models need to be used, the calculation amount is different, and the required time for transmitting the big data to the network is different). Therefore, the network side needs to negotiate and use different network models according to different terminals and requirements, and allocate related parameters (such as QoS parameters) of different data streams according to the working requirements of different terminals, so as to ensure that reasonable and timely large data analysis results can be transmitted between the terminal and the network side. Therefore, the following technical scheme of the embodiment of the application is provided. 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.
Fig. 4 is a schematic flowchart of a management method of a network model provided in an embodiment of the present application, and as shown in fig. 4, the management method of the network model includes the following steps:
step 401: the terminal sends a first message to a network element at a network side, wherein the first message carries first model information, and the first model information is model information stored by the terminal or requested model information.
In this embodiment, the network side network element is a core network element or an access network element. Further, optionally, the core network element may be a core network control plane element, and the access network element may be a base station.
The technical solution of the embodiment of the present application can be applied to, but is not limited to, a 5G network and a 4G network. According to different network types, the implementation of the core network element and the access network element is different. Taking the 5G network as an example, the core network element may be an Access Management Function (AMF) element, and the Access network element may be a gNB.
Step 402: and the terminal receives a second message sent by the network element at the network side, wherein the second message carries second model information, and the second model information is allowed model information or configured model information of the terminal.
In this embodiment of the present application, the negotiation of the network model may be implemented by, but not limited to, a registration procedure or a Radio Resource Control (RRC) connection establishment procedure.
In an alternative, the negotiation of the network model is implemented by a registration procedure. Accordingly, the first message is a registration request message, and the second message is a registration request reply message.
In another alternative, the negotiation of the network model is implemented through an RRC connection establishment procedure. Correspondingly, the first message is an RRC connection setup complete message, and the second message is an RRC connection setup complete reply message.
In the embodiment of the present application, the first message sent by the terminal to the network element on the network side carries first model information, where the first model information is model information stored by the terminal or requested model information. And the second message sent by the network element on the network side to the terminal carries second model information, wherein the second model information is allowed model information or configured model information of the terminal. The following description is provided for the specific implementation of the first model information and the second model information, and it should be noted that the following description of the model information may be applied to the first model information and also applied to the second model information.
■ the model information includes a model identification of at least one model.
(1) In an alternative, the model identification is used to identify a complete model. In this way, one model corresponds to one model identification. For example: model 1 corresponds to ID1 and model 2 corresponds to ID 2.
(2) In another alternative, the model identification is used to identify a portion of a model. In this manner, a model may correspond to multiple model identifications, each model identification corresponding to a portion of the model. For example: one model corresponds to the following 2 model identities: identification 1, identification 2, the model comprises the following 2 components: the system comprises a submodel 1 and a submodel 2, wherein the identifier 1 is used for identifying the submodel 1, and the identifier 2 is used for identifying the submodel 2.
Further, optionally, the model identifier is composed of two parts of information, specifically, the model identifier includes first identifier information and second identifier information, where the first identifier information is used to identify a model, and the second identifier information is used to identify a part of the model. For example: the 2 model identifications corresponding to one model are respectively: ID1+ ID1 for ID1 and ID1+ ID2 for ID1, ID1 for submodel 1 (i.e., submodel 1 in the model), and ID2 for submodel 2 (i.e., submodel 2 in the model).
Further, optionally, the model identifier is only composed of a part of information, specifically, the model identifier includes third identification information, and the third identification information is used for identifying a part of one model. For example: the 2 model identifications corresponding to one model are respectively: id1, Id2, Id1 identifying submodel 1 in the model and Id2 identifying submodel 2 in the model.
■ further optionally, the model information further includes additional information of the at least one model.
In an alternative, the additional information includes at least one of: the model type, the algorithm identification corresponding to the model, the service information corresponding to the model, the version information of the model and the resource information of the downloaded model.
Here, the model types are, for example: DNN model, RNN model, CNN model, MPL model, and the like.
Here, the service information corresponding to the model includes, for example: and (5) service identification.
Here, the resource information of the download model includes, for example: an IP address of a service server of the download model, a Uniform Resource Locator (URL) of the download model, and the like.
In this embodiment, optionally, when the terminal stores the model information, each model identifier may store one or more corresponding items of the additional information, and when the terminal interacts with the network side, the model identifier and one or more corresponding items of the additional information may be used as independent parameters for interaction. Or,
in this embodiment of the application, optionally, when the terminal stores the model information, one or more items of the additional information may be directly stored as a part of the model identifier, and when the terminal interacts with the network side, one or more items of the additional information interact as a part of parameters in the model identifier.
■ further optionally, the model information further includes a network identification corresponding to the at least one model.
Here, the model identification is globally unique; or the model identification is unique under a specific network, and the specific network is determined based on the network identification corresponding to the model identification.
Here, the network identifier is used to indicate that the model identifier is allocated by a specific network; and/or, the network identification is used for indicating that the model identification is used under a specific network; wherein the particular network is determined based on the network identification.
For example: the model identification (and optionally additional information) may be operator Network assigned (e.g., Public Land Mobile Network (PLMN) assigned), or Non-Public Network (NPN) assigned, or Service Provider (SP) assigned, or other type of Network assigned. Based on this, each model identification may correspond to a network identification (e.g., PLMN ID, or NPN ID, or SP ID) for distinguishing that the model identification is assigned (i.e., decided) by a specific network. Further, each model identification may or may not be globally unique (e.g., unique under a particular network). In addition, the network identifier may also limit the terminal to use or report the corresponding model identifier in a specific network. Several examples of optional model information are introduced below, and the following examples take the example that the model information includes a model identifier and a network identifier, and optionally, the model information may further include other more information, such as one or more items of accessory information.
Example 1: model information is PLMN ID + model identification, wherein a model identification uniquely identifies a model within the PLMN indicated by the PLMN ID. Here, the model identification and the network identification (e.g., PLMN ID) may be two parameters that are independent. Alternatively, the Model identifier may also be a partial parameter of the network identifier, for example, the Model identifier is PLMN ID + Model ID.
Example 2: the model information is SP ID + model identification, where the model identification uniquely identifies a model within the SP indicated by the SP ID. Here, the model identification and the network identification (e.g., SP ID) may be two independent parameters. Alternatively, the Model ID may be a partial parameter of the network ID, for example, the Model ID is SP ID + Model ID.
Example 3: the model information is a model identifier, which may be standardized (i.e., the model identifier is globally unique), or may be assigned and/or used by the terminal under a specific network (i.e., the model identifier is unique under the specific network). Optionally, the model identifier may include a network identifier (e.g., PLMN ID).
■ further, optionally, the model information also includes model capabilities supported by the terminal.
In an alternative, the model capabilities supported by the terminal include at least one of:
the maximum number of layers of models supported by the terminal;
model types supported by the terminal;
the computing power of the terminal.
Here, the computing capability of the terminal may refer to the computing capability of the terminal for a specific model or the computing capability of the terminal itself, and the computing capability may be described by the time required for computing or by the rate of computing, which is not limited in this embodiment of the application.
● in an optional manner of the present application, the base station may broadcast the model information through cell broadcast information, and after receiving the model information, the terminal may determine whether to access the cell and a corresponding network (e.g., a core network) according to the model information. Here, the access may refer to any one or more of: random access, RRC connection establishment, registration request, session establishment and session modification.
It should be noted that the session in the embodiment of the present application may be, but is not limited to, a Protocol Data Unit (PDU) session.
● in an optional manner of this application, the first message is a non-access stratum (NAS) message; the first model information is carried in an AS layer and/or an NAS layer of the NAS message.
Here, the NAS message sent by the terminal includes a NAS layer and an AS layer, where the AS layer is read by an access network element (e.g., a base station), and the NAS layer is directly forwarded to the core network element by the access network element (e.g., the base station). Further, the information carried in the AS layer is used for an access network element to determine a core network element, and the NAS message is sent to the core network element.
In one example, the first model information is carried at a NAS layer of the NAS message. And after receiving the NAS message, the access network element directly forwards the NAS message to a core network element.
In another example, the first model information is carried at an AS layer of the NAS message. And after receiving the NAS message, the access network element reads the AS layer of the NAS message, determines a corresponding core network element according to the information of the AS layer, and forwards the NAS message to the corresponding core network element.
In yet another example, a portion of the first model information is carried at an AS layer of the NAS message and another portion is carried at a NAS layer of the NAS message. And after receiving the NAS message, the access network element reads the AS layer of the NAS message, determines a corresponding core network element according to the information of the AS layer, and forwards the NAS message to the corresponding core network element.
● in an optional manner of the present application, the second model information is determined by a core network element; alternatively, the second model information is determined by a service server.
In one example, the second model information is determined by a core network element. Specifically, after receiving a NAS message sent by the terminal, the core network element acquires first model information from the NAS message, and determines which model information in the first model information is allowed to be used or allocates new model information (i.e., the second model information) to the terminal. Here, optionally, the network element of the core network is an AMF.
In another example, the second model information is determined by a traffic server. Specifically, after receiving an NAS message sent by a terminal, a core network element acquires first model information from the NAS message, forwards the first model information to a service server, and determines which model information in the first model information is allowed to be used or allocates new model information (i.e., the second model information) to the terminal by the service server, and sends the new model information to the core network element. Here, optionally, the core network element is an 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 model information that is determined by the core network element or the service server from the first model information and is allowed to be used. Or the second model information is different from the first model information, that is, the second model information is newly allocated to the terminal by the core network element or the service server.

Alternatively, the service server directly transmits the contents of the model to the terminal without a request from the terminal. The service server may be a core network element, an access network element, or an edge computing server.
It should be noted that, since the model identifier in the second model information may identify a complete model or a part of a model, the model content downloaded by the terminal from the service server may be the complete content of a model or a part of a model.
