AI Technical Summary
Technical Problem
In non-terrestrial networks, due to the large cell size, UEs need to frequently perform cell reselection and random access, leading to RACH congestion and high network signaling load, which affects service continuity and network performance.
Method used
By establishing a mapping between the UE and the network, and based on data volume thresholds, PLMN ID, cell ID, and contention resolution timers, the cell reselection process is optimized, reducing unnecessary random access and network signaling.
Benefits of technology
It effectively reduces network and UE signaling, lowers RA congestion and network load, saves UE energy consumption, and improves service continuity and network efficiency.

Abstract
A method for enhancing cell reselection in which a UE receives a mapping from a network / gNB, and if there is data to transmit, the UE determines a candidate cell for cell reselection and for potentially performing random access at the candidate cell based on the provided mapping.
