Flow-based selective reverse tunneling in wireless local area network (WLAN)-cellular systems
Abstract
At least one subscriber is subscribed to both a cellular network and a wireless local area network (WLAN). The subscriber is located in the WLAN. Flows of the subscriber are provided for transfer. Each flow comprises packets. For each flow a determination is made on whether that flow is to be routed directly through the WLAN or through both the WLAN and cellular network. Each flow's packets are routed based on that flow's routing determination.
