Samsung patents smoother wireless handovers for 5G network nodes

This patent describes a method for 5G network nodes to switch connections between different parts of the network without dropping data. It uses a technique where the device connects to the new node before fully disconnecting from the old one, ensuring a continuous flow of information.

Why it mattersThis improves the reliability of 5G networks, which is essential for supporting stable connections for smart cities, connected cars, and other IoT devices that require constant data transmission.

In the filing’s own words

The disclosure relates to: a communication technique for merging an IoT technology with a 5G communication system for supporting a higher data transmission rate than a 4G system; and a system therefor. The disclosure can be applied to intelligent services (for example, smart homes, smart buildings, smart cities, smart cars or connected cars, healthcare, digital education, retail businesses, security- and safety-related services, and the like) on the basis of a 5G communication technology and an IoT-related technology. The disclosure discloses a method and apparatus for handover of a wireless backhaul node.

What exactly they claim (claim 1)

1. A method performed by an integrated access and backhaul (IAB) node in a wireless communication system, the method comprising: receiving, from a source IAB node, a handover command message indicating a dual active protocol stack (DAPS) handover, wherein the handover command message includes target backhaul adaptation protocol (BAP) configuration information; performing a random access procedure to a target IAB node based on the handover command message; determining whether the random access procedure to the target IAB node is completed successfully and a first uplink resource is received from the target IAB node, based on a determination that the random access procedure to the target IAB node is completed successfully and the first uplink resource is received from the target IAB node, transmitting, to the target IAB node, uplink data based on the target BAP configuration information; and determining whether downlink data is not received from the source IAB node for a predetermined time, releasing a connection with the source IAB node based on a determination that the downlink data is not received from the source IAB node for the predetermined time.
