Abstract
Architecture for performing WLAN offload in a wireless device is disclosed. In an exemplary embodiment, an apparatus includes an application section configured to form IP packets from data to be transmitted, a modem section configured to apply a cellular protocol to the IP packets to form cellular protocol packets, an endpoint configured to encapsulate the cellular protocol packets to form outer IP tunnel packets, and a WLAN interface configured to transmit the outer IP tunnel packets over a WLAN communication channel. In another exemplary embodiment, an apparatus includes a WLAN interface configured to receive outer IP tunnel packets over a WLAN communication channel, an endpoint configured to extract cellular protocol packets from the outer IP tunnel packets, a modem processor configured to remove a cellular protocol from the cellular protocol packets to form IP packets, and an application processor configured to extract received data from the IP packets.
