Systems and methods supporting WLAN-WWAN mobility in devices

An apparatus for wireless communication, said apparatus comprising:

• means for identifying, by a user equipment (UE), a data stream on a first access network, wherein the data stream is associated with an access point name (APN), and the first access network comprises one of:
• a wireless wide area network (WWAN) or a wireless local area network (WLAN);
• means for determining, by the UE, a second access network different from the first access network for offloading the data stream, wherein the second access network comprises one of:
• the WWAN or the WLAN;
• means for handing off the data stream, by the UE, from the first access network to the determined second access network while maintaining Internet Protocol (IP) continuity by utilizing the APN associated with the data stream;
• and
• means for routing packets of the data stream, by the UE, to the determined second access network in accordance one or more of an operator policy or a user setting,
• wherein the UE has an applications processor and a modem processor, said modem processor having an IP flow Multi Access Packet Data Network Connectivity (MAPCON) engine that performs control functions for intelligent WLAN control, a WiFi monitor proxy that interacts with a WiFi monitor of the applications processor to receive WiFi related parameters that at least include WiFi signal quality, and an IP flow MAPCON policy manager that determines an access network among WWAN and WLAN,
• wherein an IP flow MAPCON radio access technology (RAT) manager of the IP flow MAPCON engine determines and selects an access network according to input from the WiFi monitor proxy and the IP flow MAPCON policy manager, and
• wherein the applications processor has an IP flow MAPCON engine proxy that interacts with the IP flow MAPCON engine to perform part of the handing off the data stream initiated by an IP flow MAPCON handoff manager of the IP flow MAPCON engine, and an IP flow MAPCON router that routes packets to the at least one of the determined second access network.
