Abstract

A method and apparatus supporting handoff using simulcasting of multimedia information via a broadband access gateway are disclosed. A broadband access gateway supporting both a personal area network and a broadband network may receive multimedia information simultaneously transmitted to an associated access device by a wide area network. The broadband access gateway may detect the presence of the associated access device, and the associated access device may accept the received multimedia information. The broadband access gateway may send the received multimedia information to the associated access device, and may communicate with the wide area network regarding the presence within the personal area network of the associated access device.
