1. A method of testing mum-mode devices for multi-mode system selection capability, said method comprising: parsing of system entries from a Universal Integrated Circuit Card (UICC) with respect to a plurality of attributes defined for multimode system selection (MMSS), wherein said system entries are generated in a multi-mode device under test (DUT) responsive to broadcast from a network simulator comprising base station emulation hardware; producing parameters based upon said system entries for different network system modes as simulated by said network simulator; configuring said network simulator with said parameters; and verifying system selection behavior under respective network system modes in an automated fashion.
