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