Abstract
Wireless communication in a radio access network may be implemented in a manner where a user equipment (UE) with multiple Universal Subscriber Identity Modules (USIMs) selects a system based on the system's preference status among the USIMs of the UE. A system that is home to all the UE's USIMs is selected over one that is home to some USIMs but roaming for others. A system that is home to some USIMs but not provisioned for other USIMs is selected over one that is roaming to all USIMs. A system that is roaming to all USIMs is selected over one that is roaming to some USIMs but not provisioned for other USIMs. Ranking of systems may be done independently by USIM or may be done using a combined ranking method that considers other USIMs prior to an individual USIM indicating a system priority. Manual system selection may also be used.
