Roaming Selection based on Network Quality

原文（中国語）

A method and system for providing network services in a region involves managing handovers (HO) between a source Public Land Mobile Network (PLMN) and a target PLMN. User Equipment (UE) receives radio signals from both PLMNs and receives/determines at least a Signal to Interference & Noise Ratio (SINR) and Reference Signal Received Power (RSRP) of the radio signal. A determination is made whether a HO is permitted or prohibited based on whether the target RSRP and SINRs from both PLMNs exceed certain thresholds. Additional criteria for permitting or prohibiting HO include cell load conditions. Predictive models, potentially using Artificial Intelligence/Machine Learning (AI/ML), may predict HOs based on roaming data. The PLMNs may operate across various cellular technologies, including GSM/2G, UMTS/3G, LTE/4G, or NR/5G.
