AI Technical Summary

Technical Problem

Current wireless communication technologies for non-terrestrial networks (NTN) face challenges in store and forward operations, particularly in establishing and maintaining connectivity between user equipment (UE) and satellites, as well as between satellites and ground networks.

Method used

A wireless communication method for NTN that involves configuring timers at the base station and user equipment based on the radio access technology (RAT) type, specifically extending timers for the NTN store and forward (S&F) mode to accommodate the unique connectivity challenges.

Benefits of technology

This approach enhances the reliability and efficiency of NTN communication systems by optimizing timer values for the S&F mode, ensuring stable and extended connectivity during signaling/data exchanges between UE, satellites, and ground networks.

Abstract

A wireless communication method for non-terrestrial network (NTN) applied to a base station side includes configurating, by a base station to a user equipment, an operation associated with at least one timer when a communication system is in an NTN store and forward (S&F) mode. A wireless communication method for non-terrestrial network (NTN) applied to a user equipment (UE) side includes receiving, by a UE from a base station, an operation associated with at least one timer when a communication system is in an NTN store and forward (S&F) mode.
