Samsung patents faster cell switching for 5G and 6G networks

Patent drawing
Patent drawing from the official filing.

Samsung has filed a patent for a method that helps mobile devices switch between cell towers more quickly in 5G or 6G networks. The system pre-loads settings for nearby towers and uses a fast signal to trigger the switch, reducing the time the phone spends disconnected.

Why it mattersThis could lead to smoother video calls and faster data speeds by minimizing the brief drop in connection when moving between cell towers.

In the filing’s own words

The disclosure relates to a 5G or 6G communication system for supporting a higher data transmission rate. Disclosed is a method of performing a L1/L2 Triggered Mobility, LTM, cell switch in a telecommunication system, comprising the steps of: a User Equipment, UE, being configured with an LTM candidate cell configuration by receiving a reconfiguration message, via RRC, from a telecommunication network, the message including the LTM candidate cell configuration; applying the LTM candidate cell configuration for a target cell indicated in a received MAC Control Element, CE, upon receipt of an LTM triggering MAC CE from the network; performing LTM cell switch to the target cell upon the reception of LTM triggering MAC CE; and sending a reconfiguration complete message to the target cell during the LTM switch procedure.

What exactly they claim (claim 1)

1. A method performed by a user equipment (UE) in a wireless communication system, the method comprising: receiving, from a base station, a radio resource control (RRC) reconfiguration message including layer 1/layer 2 (L1/L2) triggered mobility (LTM) configuration information; transmitting, to the base station, a first RRC reconfiguration complete message, as a response to the RRC reconfiguration message; receiving, from the base station, a medium access control (MAC) control element (CE) to trigger an LTM cell switch procedure to a target cell; performing the LTM cell switch procedure based on the MAC CE; and transmitting, to the target cell, a second RRC reconfiguration complete message for a completion of the LTM cell switch procedure.
