Latest Patents

Kim’s latest patent work includes inventions titled “Multi-SIM Device and Operation Method Thereof.” The described technologies address how a device allocates radio frequency (RF) resources when multiple SIMs request service at overlapping times.

One invention describes a multi-SIM device with multiple SIMs, RF resources, and a baseband processor. Some RF resources support a non-limited channel configuration, while others support a limited configuration under a radio resource control (RRC) protocol. When resource requests from two or more SIMs overlap, the processor uses information about their respective networks to assign the configurations.

A related invention describes a device with two SIMs connected to separate networks and two RF resources, one supporting a non-limited channel configuration and the other a limited configuration. Its baseband processor selectively assigns the resources to the SIMs based on information about the networks.

Career Highlights

Kim’s patent work focuses on multi-SIM operation and the coordination of wireless resources. The described inventions aim to manage competing network demands through resource assignment informed by network characteristics.
