Abstract
Many commercially deployed devices support more than one SIM cards. Support for multi-USIM is currently handled in an implementation-specific manner without any support from 3GPP specifications. With the increased complexity of 5G-capable UEs and with growing demand for multi-USIM devices in the market, it becomes important to consider system enhancements that would allow for more efficient solution involving required support to UE from 5G core and 5G-RAN.
