摘要： An Ethernet-PON integrates broadcast/communication through time division multiplexing, which provides users with high-speed, high-volume communication data and high-quality, real-time digital broadcast/image data. An OLT performs a switching operation on a plurality of digital broadcast/image data received from an external broadcaster according to respective broadcast/image selection information from users, time-division-multiplexes the data into a broadcast/image signal, multiplexes the signal and communication data from an IP network into a frame, and electro-optically converts the frame and transmits to the frame to ONTs through an optical splitter. Each ONT receives and photoelectrically converts the signal from the OLT, and performs frame & time-slot demultiplexing to output the entire received communication signals and broadcast/image information contained in a time-slot assigned to the ONT to a corresponding user. The ONT receives a communication signal and broadcast/image selection information from the user, and outputs them to the OLT through the splitter.

摘要： An Ethernet-PON that accommodates real-time broadcast/image signals and provides security for broadcast/image signals, allows user authentication without a CAS. An OLT in the Ethernet-PON switches digital broadcast/image data signals from a broadcaster according to respective broadcast/image selection information of users, and scrambles the switched broadcast/image data on a user-by-user basis. The scrambled data is multiplexed and converted to a broadcast/image optical signal, which is transmitted, combined with a communication signal from an IP network, to ONTs through an optical splitter. The ONTs select broadcast/image data from the broadcast/image signals according to the respective broadcast/image selection information.

摘要： A system and method for controlling layer 3 (L3) handover of a mobile node is disclosed. A mobile Internet protocol (MIP) network includes a plurality of mobile nodes, a plurality of users, a plurality of routers, and a handover control system. The plurality of routers periodically report state information of a plurality of base stations and the plurality of routers to a handover control system, which receives the state information to produce a handover topology map and maps a current location of the plurality of mobile nodes to the handover topology map to search for a plurality of target routers having a highest probability of handover. The handover control system transmits the state information of the searched target routers to the mobile nodes. Thus, the L3 handover time can be shortened to tens of ms or less, allowing for seamless real-time multimedia service even though a terminal moves.

摘要： A handover control method and apparatus are provided to efficiently buffer packets in a Mobile Worldwide Interoperability for Microwave Access (WIMAX) network. A serving radio access station (S-RAS) and an access control router (ACR) divide and buffer packets to be sent to a mobile station before and after a predetermined message exchange process. The Access control router (ACR) sequentially tunnels a packet buffered in the serving radio access station (S-RAS) and a packet buffered in the Access control router (ACR) into a target radio access station (T-RAS) when a handover for the mobile station is completed. Since an unnecessary buffering operation is not performed in the Access control router (ACR) and the radio access station (RAS), a resource waste may be avoided.
