Abstract: A method for authenticating a circuit switched (CS) call on a virtual subscriber identity module (VSIM) includes: authenticating the VSIM for a packet switched (PS) call connection using authentication information obtained from a remote server through a software subscriber identity module (soft-SIM) connection to the remote server; initiating a call connection on a CS radio access technology (RAT) between the VSIM and a first communication network; and authenticating the VSIM CS call connection to the first communication network through the VSIM PS connection in response to an authentication request for the call connection on the CS RAT.

Abstract: In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. The apparatus may receive a priority list associated with preferred radio frequencies from a serving base station. In certain aspects, each radio frequency of the preferred radio frequencies associated with a first set of base station may operate on a first RAT. In certain other aspects, the apparatus may determine if the UE is able to reselect to the first RAT. In certain other aspects, the apparatus may perform a rank-based cell reselection procedure based on signal strength when the UE is unable to reselect to the first RAT.
