Long Term Evolution (LTE) is becoming the dominant cellular networking technology, shifting network away from its circuit-switched legacy towards a packet-switched that resembles Internet. To support voice calls over LTE network, operators have introduced Voice-over-LTE (VoLTE), which dramatically changes how are handled, both user equipment and infrastructure perspectives. We find this dramatic shift opens up number of new attack surfaces not been previously explored. call attention to matter, paper presents systematic security analysis.
