Samsung patents phone method to scan cell signals while on standby

This patent describes a method for phones to measure nearby cell tower signals while in a low-power standby mode. The device prioritizes which frequencies to check based on previous connection quality and sends the results to the network when it reconnects.

Why it mattersThis could help phones switch between cell towers more efficiently, potentially improving connection stability and battery life during idle periods.

In the filing’s own words

An embodiment of the disclosure relates to an electronic device for channel measurement in a wireless communication system and an operating method thereof. The electronic device may include: a communication circuit, and a processor, and the processor is configured to: obtain information related to measurement from a message related to release of a radio resource control (RRC) connection of the electronic device to a network, identify frequencies for measurement while the electronic device is in an RRC idle or an RRC inactive state with the network, generate a frequency list including at least one of the frequencies for measurement based on a priority of a frequency used for access between the electronic device and the network and a channel state between the electronic device and the network, sequentially perform measurement based on a priority of at least one frequency included in the frequency list while the electronic device is in an RRC idle state or an RRC inactive state with the network, and control the communication circuit to transmit a result of the measurement to the network based on transition to an RRC connected state.

What exactly they claim (claim 1)

1. An electronic device comprising: a communication circuit; at least one processor operatively connected to the communication circuit; and memory storing instructions, wherein the instructions, when executed by the at least one processor, cause the electronic device to: receive a message related to release of a radio resource control (RRC) connection of the electronic device to a network; detect that the received message includes information related to measurement and identify first frequency information related to cell reselection included in a first system information block (SIB) and second frequency information related to a carrier aggregation (CA) function and/or a dual connectivity (DC) function included in a second SIB received from the network while the electronic device is in an RRC idle or an RRC inactive state with the network; generate at least a part of a frequency list from at least one of the first frequency information or the second frequency information based on a priority of a frequency used for access between the electronic device and the network and a channel state between the electronic device and the network; perform measurement on at least one frequency included in the generated frequency list while the electronic device is in an RRC idle state or an RRC inactive state with the network; and detect that an RRC state is transitioned from the RRC idle state or the RRC inactive state to an RRC connected state and transmit, via the communication circuit, a result of the measurement to the network.
