Claim of US Patent No. 10,893,478

1. A multi-subscriber identification module (SIM) device comprising:a first SIM interface;
a second SIM interface; and
at least one processor configured to implement:
a base station (BS) searcher configured to perform a resynchronization operation for securing synchronization with a BS or a measurement operation for measuring signal quality of the BS based on a request received from the first SIM interface; and
a searcher scheduler configured to receive the request for use of the BS searcher from the first SIM interface, and output, to the first SIM interface, one from among a start signal, a wait signal or a grant signal based on whether the first SIM interface is granted use of the BS searcher based on the request and a schedule for the BS searcher.
