Samsung patents method to help phones switch satellite cells faster
This patent describes a way for mobile devices to manage connections in satellite networks. It uses the speed at which the signal strength changes to decide when to start looking for a better satellite cell.
In the filing’s own words
A method for cell measurement by a user equipment (UE) in a non-terrestrial network (NTN) communication system is provided. The method includes camping to an NTN cell; receiving at least one parameter from the camped NTN cell; determining a rate of change (ROC) of signal strength of the camped NTN cell; determining whether a neighbor cell measurement criterion is met based on the at least one parameter and the ROC of the signal strength of the camped NTN cell; and initiating measurement for at least one neighbor cell based on the neighbor cell measurement criterion being met.
What exactly they claim (claim 1)
1. A method for cell measurement by a user equipment (UE) in a non-terrestrial network (NTN) communication system, comprising: camping on an NTN cell; receiving at least one parameter from the camped NTN cell; determining a rate of change (ROC) of signal strength of the camped NTN cell; determining whether a neighbor cell measurement criterion is met based on determining whether remaining time of the service for the NTN cell is less than a specified threshold, and whether a ROC criterion is met; and initiating measurement for at least one neighbor cell, when the neighbor cell measurement criterion is met.
