A home network system for supporting continuity of data transfer destined for an MS (Mobile Station) when the MS moves between wireless nodes, comprising a server for storing multimedia data and a network connecting the server to the MS via the wireless nodes. A first wireless node, while transferring predetermined data from the server to the MS, senses that a connection with the MS is cut off. The predetermined data to be transferred to the MS is then buffered in one or more of the wireless nodes at a time point of disconnection with the MS, and the first wireless node maintains a connection with the server. A second wireless node in the home network system establishes a connection with the MS and, in response a data transfer request from the MS, provides the buffered data to the MS.
