By introducing 5GC support capabilities, the AIML system (AIMLsys) supports AI / ML operations at the application layer.

[0173] In some embodiments, the scope of AL services in the communication network can be expanded, thereby using AI / ML technology to realize the intelligence of 5GC and air interface, provide automation of the communication network and improve the efficiency of the 5G network architecture.

[0174] Figure 2A is a schematic diagram of an AI functional framework for a communication system. As shown in Figure 2A , an AI / ML functional framework for the NR air interface can be introduced for the RAN. This functional framework 2100 can include the following five functions: data collection function 2101, model training function 2102, management function 2103, inference function 2104, and model storage function 2105.

[0175] In some embodiments, data collection functionality 2101 is used to provide input data to model training, management, inference, and other functions. The data collected through data collection may include at least one of the following: training data, monitoring data, and inference data.

Inference data may be data provided to the inference functionality.

[0176] In some embodiments, the model training function 2102 is used to implement AI / ML model training, verification, and testing. Here, as part of the model verification process, the model training function can generate model performance indicators. In some cases, the model training function can also be responsible for data preparation (e.g., data preprocessing and cleaning, formatting, and conversion) based on the training data from the data collection function. The model training function can provide the trained, verified, and tested model to the model storage function, or provide an updated version of the model to the model storage function.

[0177] In some embodiments, the management function 2103 is used to perform operational supervision (e.g., selection, activation, deactivation, switching, fallback) and monitoring (e.g., performance) of the model and its functions. In some embodiments, the management function may also be responsible for decision-making to ensure that appropriate reasoning operations are implemented based on data from the data collection function and the reasoning function. The management instructions of the management function can be information used to manage the reasoning function. This information may include the selection, activation, deactivation, switching, fallback to non-AI / ML operations, etc. of the model. The model transfer request of the management function can be used to request a model from the model storage function. The management function can provide performance feedback / retention requests to the model training function, for example, for training or updating the model.

[0178] In some embodiments, the reasoning function 2104 is used to provide the output of the process of applying the model or model function. This process can use the data provided by the data collection function (i.e., reasoning data) as input. In some embodiments, the reasoning function can also be responsible for data preparation (e.g., pre-processing and cleaning, formatting, and conversion of data) based on the training data from the data collection function. The output of the reasoning function can be used by the management function to monitor the performance of the model or model function.

[0179] In some embodiments, the model storage function 2105 can be used to store trained / updated models that can be used to perform inference. The model storage function can pass the model to the inference function.

[0180] Figure 2B is a schematic diagram of an ML model provisioning architecture for a communication system. As shown in Figure 2B , in a 5G system architecture, NWDAF 2201 may include an analytics logical function (AnLF). The AnLF may provide services using a trained ML model from another NWDAF 2202.

[0183] The ML model provisioning architecture shown in Figure 2B needs to be able to support the functional framework 2100 shown in Figure 2A. In some scenarios, model-based reasoning can be implemented by access network equipment (e.g., base stations) and / or network elements in the core network. This requires sending the model to the base stations and / or network elements.

The processor calls the instructions stored in the memory to implement any of the above methods or implement the functions of the various units or modules of the above devices, wherein the processor is, for example, a general-purpose processor, such as a central processing unit (CPU) or a microprocessor, and the memory is a memory within the device or a memory outside the device. Alternatively, the units or modules in the device can be implemented in the form of hardware circuits, and the functions of some or all of the units or modules can be realized by designing the hardware circuits. The above-mentioned hardware circuits can be understood as one or more processors; for example, in one implementation, the above-mentioned hardware circuit is an application-specific integrated circuit (ASIC), which realizes the functions of some or all of the above units or modules by designing the logical relationship of the components in the circuit; for example, in another implementation, the above-mentioned hardware circuit can be realized by a programmable logic device (PLD). Taking a field programmable gate array (FPGA) as an example, it can include a large number of logic gate circuits, and the connection relationship between the logic gate circuits is configured by configuring the configuration file, thereby realizing the functions of some or all of the above units or modules. All units or modules of the above devices can be realized in the form of software called by the processor, or in the form of hardware circuits, or in part by the form of software called by the processor, and the rest by hardware circuits.

In one implementation, the processor can be a circuit with instruction reading and execution capabilities, such as a central processing unit, a microprocessor, a graphics processing unit (GPU) (which can be understood as a microprocessor), or a digital signal processor (DSP); in another implementation, the processor can implement certain functions through the logical relationship of the hardware circuit. The logical relationship of the above-mentioned hardware circuit is fixed or reconfigurable. For example, the processor is a hardware circuit implemented by a dedicated integrated circuit or a programmable logic device, such as an FPGA. In a reconfigurable hardware circuit, the process of the processor loading a configuration document and implementing the hardware circuit configuration can be understood as the process of the processor loading instructions to implement the functions of some or all of the above units or modules. In addition, it can also be a hardware circuit designed for artificial intelligence, which can be understood as an ASIC, such as a neural network processing unit (NPU), a tensor processing unit (TPU), a deep learning processing unit (DPU), etc.
