1. A computer-readable storage medium including instructions executable by a computer to cause the computer to perform operations comprising:
receiving, from a serving Master Cell Group (MCG) of a terminal, a measurement report of the terminal, the measurement report including a plurality of signal measurements, each signal measurement associated with a Secondary Cell Group (SCG) represented by a Physical Cell Identifier (PCI) and an Absolute Radio-Frequency Channel Number (ARFCN);
identifying an unlisted SCG among the plurality of signal measurements, the unlisted SCG represented by a PCI and an associated ARFCN that do not correspond to any single SCG in a Neighbor Relations Table (NRT) of the serving MCG;
identifying one or more nearby MCG within a threshold distance of the serving MCG;
counting a number of SCG in the NRT of each nearby MCG having the PCI and the ARFCN of the unlisted SCG; and
applying a classification model to the counted number of SCG and an MCG-PCI-ARFCN identifier representing the serving MCG, the PCI, and the ARFCN to obtain a prediction value, the prediction value being a binary value indicating whether provisioning the unlisted SCG with the serving MCG and the plurality of nearby MCG will result in PCI conflict.
