Claim:
1. A method for seamless session mobility on a wireless communication device comprising a physical cellular interface and a physical wireless local area network (WLAN) interface, the method comprising the wireless communication device: anchoring a data session for an application to a logical cellular interface associated with the physical cellular interface, wherein the wireless communication device comprises a logical application layer in which the application is implemented and a logical physical layer comprising the physical cellular interface and the physical WLAN interface; and routing data for the data session sent to the logical cellular interface by the application to the physical WLAN interface for transmission via the physical WLAN interface in an instance in which the wireless communication device has an active connection to a WLAN, wherein routing data for the data session to the physical WLAN interface is performed under control of an inter-radio access technology (iRAT) manager implemented in a logical layer disposed in a lower layer than the logical application layer; and wherein use of the physical WLAN interface to transmit the data for the data session is transparent to the application.
