Abstract
Official abstract text for this publication.
A method and an apparatus for selecting UE through steps of requesting analytics for selecting the UE to participate in an AI/ML operation from an NWDAF in a core network and selecting the UE based on the analytics.
First claim
Opening claim text (preview).
What is claimed is: 1 . A network data analytics function (NWDAF) in a core network, comprising: a processor, a memory, and a communication device, wherein the processor executes a program stored in the memory to perform: receiving a request for analytics in user equipment (UE) level granularity from an application function (AF); collecting data from at least one UE, a network function (NF), and OAM (operations, administration, and maintenance) in the core network; and providing the analytics derived based on the data to the AF, wherein, when collecting the data, the processor performs collecting, from the OAM at the UE level granularity, packet delay for downlink (DL) and uplink (UL) per radio access bearer (RAB)/data radio bearer (DRB) per UE, and packet loss rate for the DL and the UL per the RAB/DRB. 2 . The NWDAF of claim 1 , wherein when collecting the data, the processor performs collecting RAN Throughput per UE and QoS flow retainability per UE from the OAM. 3 . The NWDAF of claim 1 , wherein when collecting the data, the processor performs collecting, from the OAM at the UE level granularity, at least one of throughput for downlink (DL) and uplink (UL) per UE, packet delay for the DL and the UL per radio access bearer (RAB)/data radio bearer (DRB) per UE, and packet loss rate for the DL and the UL per the RAB/DRB. 4 . The NWDAF of the claim 1 , wherein when collecting the data, the processor performs collecting, from the at least one UE, quality of experience (QoE) metric about either success rate of model distribution or upload success rate of results of local update. 5 . The NWDAF of claim 1 , wherein when collecting the data, the processor performs collecting, from the AF, a customized mean opinion score (MOS) about either success rate of model distribution or upload success rate of results of local update. 6 . The NWDAF of claim 1 , wherein when receiving the request for analytics in the UE level granularity from the AF, the processor performs receiving the request for the analytics from the AF in the core network. 7 . The NWDAF of claim 6 , wherein when providing the analytics derived based on the collected data to the AF, the processor performs providing the analytics derived based on the data to the AF.
