Samsung patents 5G relay method to switch data sessions

Patent drawing from the official filing.

Samsung describes a method for 5G or 6G networks where a relay device receives a command from a base station to modify its data connection. The relay then establishes a new data session and releases the direct link used to forward traffic for another device.

Why it mattersThis filing details how devices can manage data connections in advanced cellular networks, potentially improving how traffic is routed between phones and base stations.

In the filing’s own words

The disclosure relates to a 5G or 6G communication Remote UE Relay UE e.g. Network system for supporting a higher data transmission rate. A method performed by a relay user equipment (UE) in a wireless communication system is provided. The method comprises receiving, from a base station, a protocol data unit (PDU) session modification command message associated with a first PDU session, the PDU session modification command message including a cause value for requesting a PDU session reactivation, establishing a second PDU session based on the PDU session modification command message and initiating a release procedure for a PC5 direct link associated with the first PDU session established for relaying a traffic of a remote UE.

What exactly they claim (claim 1)
