摘要： A multicast transmission method in GEM mode in Gigabit-capable passive optical network and a method of processing frames. The multicast transmission method includes the steps of: (a) setting a multicast connection; and (b) transmitting multicast messages in a GEM mode, wherein said step (a) includes a first sub step (i), in which predetermined ONTs are registered to a multicast group by means of IGMP frames in the first step, and a second sub step (11), in which an OLT assigns a multicast port ID to the multicast group and the ONTs registered to the multicast group. In addition, step (b) includes a first substep (i), in which the OLT assigns a multicast port ID to a message transmitted from a router to the multicast group, and transmits the message, and a second sub-step (ii), in which an ONT, which belongs to the OLT, filters the message, to which the multicast port ID is assigned, by means of a port ID assigned to the ONT.

摘要： A high-speed WPAN (Wireless Personal Area Network) system for enabling communication between piconets is configured by at least one first device located in the child piconet. A C-PNC (Child Piconet Coordinator) device includes a C-MIB (Child Piconet Management Information Base) stores mapping information associated with devices located in the child piconet and a P-MIB (Parent Piconet Management Information Base) stores mapping information associated with devices located in a parent piconet. At least one second device is located in the parent piconet. The first device includes a C-MIB and a first B-MIB (Bridging Management Information Base), detects destination information of data using the mapping information stored in the first B-MIB to transmit data to a device located in the parent piconet, and transmits the data containing the detected information to the C-PNC device. The C-PNC device broadcasts the mapping information stored in the C-MIB and P-MIB to different piconets, and switches and transmits the data from the first device to the parent piconet. The second device includes a P-MIB and a second B-MIB, and receives the data from the C-PNC device.

摘要： 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.
