Samsung patents method for smoother 5G handovers in wireless networks

Patent drawing
Patent drawing from the official filing.

Samsung describes a method for managing how a device switches between cell towers in a wireless network. The system uses specific configuration messages to coordinate the transfer, ensuring the device stops certain measurements before completing the handover to a new network entity.

Why it mattersThis is a technical improvement for network stability that helps maintain a consistent connection as users move, though it is unlikely to be noticeable to the average consumer.

In the filing’s own words

A method for handling a handover of a user equipment (UE) in a wireless network is provided. The method includes receiving a layer trigger mobility (LTM) configuration message to perform a master cell group (MCG) cell change from a first network entity. The method includes receiving a secondary cell group (SCG) addition message from the first network entity. The SCG addition message includes at least one of a primary secondary cell (PSCell) addition configuration and a conditional PSCell addition (CPA) associated with the PSCell addition configuration, a configuration for PSCell addition and a LTM execution condition associated with the configuration, and a configuration for PSCell addition and a conditional LTM execution condition associated with the configuration. The method includes measuring and sending an MCG measurement report for handover and stopping a measurement event and execution of the associated SCG cell. The method includes performing the handover of the UE to a second network entity based on handover information.

What exactly they claim (claim 1)

1. A method for handling a handover of a user equipment (UE) in a wireless network, the method comprising: receiving, by the UE, a layer trigger mobility (LTM) configuration message to perform a master cell group (MCG) cell change from a first network entity; receiving, by the UE, a secondary cell group (SCG) addition message from the first network entity; sending, by the UE, an MCG measurement report for handover and stopping a measurement event and an execution of an associated SCG cell; and performing, by the UE, the handover to a second network entity based on handover information, wherein the SCG addition message includes at least one of: a primary secondary cell (PSCell) addition configuration and a conditional execution event (CPA) associated with the PSCell addition configuration, the PSCell addition configuration and an LTM execution condition associated with the PSCell addition configuration, or the PSCell addition configuration and a conditional LTM (C-LTM) execution condition associated with the PSCell addition configuration.
