C-NWDAF: Designing a Cloud-based Multi-Model Architecture for Network Data Analytics Function

With the explosive growth of 5G applications, the scale and complexity of network operation, management, and maintenance have increased for telecommunications operators in the B5G era. The 5G specifications defined by 3GPP have established network data analytics functions (NWDAF) and their interfaces, allowing various network functions to obtain AI model inference through subscription to NWDAF, thus achieving intelligent and autonomous management of the 5G core network. This study will use cloud services to implement a cloud-based multi-model architecture for NWDAF.
