Abstract
A system for transferring content includes a wireless local area network (WLAN) and a network module provided within the WLAN or a cellular network to alert users of available content in the WLAN and handle user requests made for content when a user has access to the cellular network. The network module, which may comprise an interworking function, delivers the content to the user through the WLAN when the user is present in a coverage area of the WLAN. The invention allows a user to view the programs available for download and request a specific program using a relatively low speed network, such as a cellular network, and download the program through a high speed network, such as a WLAN.
