Samsung patents method to manage small data transfers in 5G networks

Patent drawing
Patent drawing from the official filing.

Samsung has filed a patent for a method that helps mobile devices handle small data transmissions in 5G networks. The system monitors for changes in the connected cell during a data transfer and stops a specific timer if a change occurs, allowing the device to switch to a standby mode and select a new cell.

Why it mattersThis technical improvement aims to make 5G data connections more stable and efficient for devices that send small amounts of information, such as sensors or background updates.

In the filing’s own words

A communication method and system for converging a 5th generation (5G) communication system for supporting higher data rates beyond a 4th generation (4G) system with a technology for Internet of things (IoT) are provided. The communication method and system includes intelligent services based on the 5G communication technology and the IoT-related technology, such as smart home, smart building, smart city, smart car, connected car, health care, digital education, smart retail, security and safety services. A method performed by a terminal for small data transmission (SDT) in a wireless communication system is provided.

What exactly they claim (claim 1)

1. A method performed by a terminal for small data transmission (SDT) in a wireless communication system, the method comprising: entering an RRC INACTIVE in response to a radio resource control (RRC) release message with suspend configuration; transmitting, to a base station, an RRC resume request message for an RRC resume procedure, wherein the RRC resume procedure is initiated for an SDT; identifying whether a cell reselection occurs while an SDT procedure is ongoing; stopping a timer associated with the SDT, if the cell reselection occurs while the SDT procedure is ongoing; and entering an RRC IDLE and performing a cell selection.
