A multi-subscriber identification module (multi-SIM) device includes plural SIMs, plural radio frequency (RF) resources, and a baseband processor. The plural RF resources are assigned to the plural SIMs, a first portion of the RF resources supporting use of a non-limited channel configuration and a second portion of the RF resources supporting use of a limited channel configuration according to a radio resource control (RRC) protocol. The baseband processor, in response to RF resource use request intervals of two or more target SIMs among the plural SIMs overlapping each other, control the RF resources to support the use of the non-limited channel configuration for one of the two or more target SIMs and to support the use of the limited channel configuration for the other of the two or more target SIMs, based on information regarding networks respectively corresponding to the two or more target SIMs.

Multi-sim device and operation method thereof

A multi-subscriber identification module (SIM) device includes: a first SIM configured to use a service of a first network; a second SIM configured to use a service of a second network; a first RF resource configured to support use of non-limited channel configuration according to a radio resource control (RRC) protocol; a second RF resource configured to support use of limited channel configuration according to the RRC protocol; and a baseband processor configured to selectively assign any one of the first RF resource and the second RF resource to the first SIM and the second SIM, based on information regarding the first network and the second network.
