Publication number: 20250119715Abstract: A process is defined for consumer-controllable ML model provisioning and training in a wireless communication network. The process comprises two procedures, which respectively correspond to the two phases of an ML model provisioning process in, e.g., 5GC, i.e., the preparation/provisioning phase and the training execution phase. For the preparation/provisioning phase, new parameters are added to the request from the ML model consumer to the ML model generator (e.g., NWDAF), so that the latter can conduct the ML model provisioning according to the consumer requirements. For the training execution phase, interactions between the ML model consumer and generator(s) are considered, and the corresponding procedure for a consumer controlling the ML model training execution phase is defined.Type: ApplicationFiled: July 21, 2022Publication date: April 10, 2025Inventors: Jing Yue, Zhang Fu, Ulf Mattsson, Mirko D'Angelo, Maria Belen Pancorbo Marcos

Publication number: 20250111223Abstract: When the consumer NWDAF requests a trained machine learning model from a producer NWDAF for a set of Analytic IDs associated with a plurality of UEs, the consumer NWDAF may include a reliability requirement in the model provisioning request to indicate a required accuracy for the machine learning model. The reliability requirement may be expressed in terms of a number of UEs, a percentage of UEs. or an accuracy target. The producer NWDAF determines whether it can provide a trained model satisfying the reliability requirement and responds accordingly. If a trained model meeting the reliability requirement is available, the producer NWDAF provides the location the trained model to the consumer NWDAF.Type: ApplicationFiled: December 29, 2022Publication date: April 3, 2025Inventors: Zhang Fu, Ulf Mattsson, Maria Belen Pancorbo Marcos
