Abstract
This document describes techniques to optimize device power and user connectivity for terrestrial or non-terrestrial, e.g., low-Earth orbit (LEO) satellite, network selection by a device modem. Per the techniques, the modem is configured to not perform a scan for Terrestrial networks (TNs) during Non-Terrestrial Network (NTN) signal emission gaps; instead, the modem is configured to wait for the next NTN signal availability and connect to the NTN accordingly. To do this, the telephony framework is implemented to provide the signal emission gap information at the device location to the modem such that the modem can initiate the rescan for NTN signal at an appropriate time. TN rescanning is triggered only if the NTN signal emission gap has passed but the modem is unable to re-attach to the NTN or if the user location has changed by at least a threshold distance. The described techniques address issues with LEO satellite communication, such as signal emission gaps and limited visibility.
