Samsung patents phone power-saving mode that pauses network checks

This patent describes a method for smartphones to save battery by entering a "restricted mobility mode" when they are not moving much. The phone checks its movement and the quality of nearby cell towers to decide when to stop sending regular status updates to the network.

Why it mattersThis helps phones last longer on a single charge by reducing unnecessary communication with cell towers when the device is stationary.

In the filing’s own words

A method and a user equipment (UE) for power management by the UE connected to a network are provided. The method includes determining, by the UE, a mobility state of the UE based on satisfaction of at least one of a plurality of predefined conditions, determining, by the UE, a list of priority cells among a plurality of available cells, wherein each priority cell in the list of priority cells is associated with a priority value based on a plurality of predefined priority conditions, and switching, by the UE, the UE to a restricted mobility mode based on the determined mobility state and the priority value associated with each priority cell in the list of the priority cells, wherein switching the UE to the restricted mobility mode includes connecting the UE in one of a first sub-mode, wherein the UE refrains from transmitting a measurement report (MR) and performing cell reselection, for a predetermined time period, if the UE is in an idle state, or a second sub-mode, wherein the UE transmits the MR for a predefined number of times, if the UE is in a connected state and if the UE is configured with infinite MR configuration, wherein the infinite MR configuration corresponds to a number of MR transmitted by the UE until the UE receives a response to the MR from the network.

What exactly they claim (claim 1)

1. A method for power management performed by a user equipment (UE) connected to a network, the method comprising: determining, by the UE, a mobility state of the UE based on satisfaction of at least one of a plurality of predefined conditions; determining, by the UE, a list of priority cells among a plurality of available cells, wherein each priority cell in the list of priority cells is associated with a priority value based on a plurality of predefined priority conditions; and switching, by the UE, the UE to a restricted mobility mode based on the determined mobility state and the priority value associated with each priority cell in the list of priority cells, wherein switching the UE to the restricted mobility mode comprises connecting the UE in a first sub-mode, wherein the UE, in the first sub-mode, refrains from transmitting a measurement report (MR) and performing cell reselection, for a predetermined time period, when the UE is in an idle state.
