A method for a home network system comprising a server for storing multimedia data, a plurality of wireless nodes, a network for connecting the server to the plurality of wireless nodes and a mobile station for performing a wireless connection through at least one of said wireless nodes, the method being for providing continuity of data transfer when the mobile station is moved between different wireless zones covered by corresponding ones of the wireless nodes while data is sent from the server, the method being characterized in that it comprises the steps of: sensing, by a first wireless node that a first connection between the first wireless node and the mobile station is cut off, while the first wireless node is receiving data from the server through the network and is transferring the received data to the mobile station; upon the first connection between the first wireless node and the mobile station is being cut off, the first wireless node notifying to the server that the first connection is cut off; upon the first connection between the first wireless node and the mobile station being cut off, the server broadcasting the data from the server to all the wireless nodes in the home network system; storing the broadcast data in each of said wireless nodes; a second wireless node of said wireless nodes establishing a second connection between the mobile station and a second wireless node in the home network system, the second wireless node receiving from the mobile station, a continuous-data-transfer request for the broadcast data; upon receiving said continuous-data-transfer request, the second wireless node transferring the broadcast data stored by the second wireless node to the mobile station and notifying the server about the established second connection; receiving, by the second wireless node from the server, data subsequent to the broadcast data, and the second wireless node transferring the subsequent data to the mobile station. sensing, by a first wireless node that a first connection between the first wireless node and the mobile station is cut off, while the first wireless node is receiving data from the server through the network and is transferring the received data to the mobile station; upon the first connection between the first wireless node and the mobile station is being cut off, the first wireless node notifying to the server that the first connection is cut off; upon the first connection between the first wireless node and the mobile station being cut off, the server broadcasting the data from the server to all the wireless nodes in the home network system; storing the broadcast data in each of said wireless nodes; a second wireless node of said wireless nodes establishing a second connection between the mobile station and a second wireless node in the home network system, the second wireless node receiving from the mobile station, a continuous-data-transfer request for the broadcast data; upon receiving said continuous-data-transfer request, the second wireless node transferring the broadcast data stored by the second wireless node to the mobile station and notifying the server about the established second connection; receiving, by the second wireless node from the server, data subsequent to the broadcast data, and the second wireless node transferring the subsequent data to the mobile station.
