Abstract: 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 or a legacy modem on a mobile terminal with both kinds of modems, and providing all legacy modem functions is disclosed. In addition, methods for dynamic selection of radio in a mobile terminal capable of Rich Communications Services (RCS) capabilities, and a method for redirecting RCS traffic to an alternate network interface is also disclosed. Methods for Session Initiation Protocol module (SIP) stack functions to be distributed across different processors on a mobile terminal, and directed to different network interfaces is disclosed. Methods of adding video calling and RCS functions without encountering the dual registration problem are also disclosed.

Abstract: Methods of IP to IP handover for VoIP calls are disclosed. Handover can occur using UDP in connectionless mode to switch networks, a hybrid approach including establishing both a TCP session and a UDP session and handing off using the UDP session, utilizing a network SIP proxy to maintain connection with the IMS server while the mobile device switches networks connecting the mobile device to the SIP proxy, using a modified Connection Manager that permits multiple IP connections simultaneously, and connecting via an on-device virtual network to an on-device router which reroutes calls to the appropriate network are detailed.

Abstract: A method, computer program, and system for augmenting communications protocols. Communications are received with which at least one protocol is determined to be associated. The at least one protocol may be configured to control at least one of the communications. Parameters associated with the at least one protocol are identified. In turn, at least one rule is accessed that is based on the at least one protocol and the parameters. Subsequently, a user is provided with at least one communications-control option according to the at least one rule.
