Methods and systems of advanced real-time IP communication in a mobile terminal

摘要: A method of making Voice over Internet Protocol (VoIP) calls, legacy circuit sending/receiving Short Message Service (SMS) Long Term Evolution (LTE) modem (360, 460, 560, 660) or a (370, 470, 570, 670) on mobile terminal (300, 400, 500, 600) with both kinds modems 370, 660, 670), and providing all functions is disclosed. In addition, methods for dynamic selection radio in capable Rich Communications Services (RCS) capabilities, redirecting RCS traffic to an alternate network interface (315, 415, 515, 615) also Methods Session Initiation module (SIP) (388, 488, 588, 688) stack be distributed across different processors 600), directed interfaces 360, 615, adding video calling without encountering the dual registration problem are
