Samsung patents way for devices to switch relays while in standby mode

This patent describes a method for a remote device to stay connected to a network while in a low-power standby state. The device can switch to a different relay terminal if needed and update its network location without fully reconnecting.

Why it mattersThis improves how 5G networks manage battery life and connectivity for devices that rely on other phones or hubs to reach the internet.

In the filing’s own words

The present disclosure relates to: a communication technique for merging IoT technology with a 5G communication system for supporting a data transmission rate higher than that of a 4G system; and a system therefor. The present disclosure can be applied to intelligent services (for example, smart homes, smart buildings, smart cities, smartcars or connected cars, healthcare, digital education, small businesses, security- and safety-related services, and the like) on the basis of 5G communication technology and IoT-related technology. The present disclosure relates to a method and a device for performing, on the basis of a sidelink in a wireless communication system, a RAN notification area (RNA) update operation of a remote terminal, in an RRC_INACTIVE state, connected to a relay.

What exactly they claim (claim 1)

1. A method performed by a remote terminal in a wireless communication system, the method comprising: receiving, from a first base station, via a first relay terminal, a radio resource control (RRC) release message including information on a suspend configuration; entering an RRC inactive state, based on the information on the suspend configuration; selecting a second relay terminal based on a relay reselection procedure in the RRC inactive state; identifying whether a radio access network notification area (RNA) update (RNAU) is triggered, based on the selection of the second relay terminal; and in case that the RNAU is triggered, performing an RNAU procedure.
