Home network system and data transfer method, home network controller and terminal

The invention discloses a home network system and a data transmission method, whose kernel idea is that when various terminals within home are to be interconnected, both the wired home commumication network and the short-range wireless commumication network are applied, that is, both the wired transmission channel and the wireless transmission channel are provided, and when specific service data are transmitted, the carrier network in practice is selected and controlled by the home network controller. The invention also provides a corresponding home network controller and home network terminals. The invention can reasonably select and allocate the carrier network in terms of the type of terminals and/or the characteristics of services applied for and the present conditions of wired/wireless network resources etc., amend the performance limitation of single transmission path, and utilize spare network resources to maximum extent.
