摘要： A system that allows multiple bundles of plesiochronous digital hierarchy (PDH) payload data streams to be synchronously trasmitted from one point to another is described. The system multiplexes multiple stages of the PDH using a single clock signal. This removes the need to perform stuffing and de-stuffing of the data streams at the various stages of the multiplexing.

摘要： A mobile Internet Protocol service provider system implements home agent functionality in two separate devices. One device, the home registration agent, is devoted to registration of the mobile node and session control. The other device, the home tunneling agent, is devoted to tunneling and routing functions for the foreign agent. The home registration agent can be a general purpose computer. The home tunneling agent is preferably implemented in a robust routing device, such as an IP switch or router. Multiple home tunneling agents or home registration agents can be implemented in the respective devices as multiple instantiations of a home registration agent or home tunneling agent software program.Foreign agent functionality for mobile IP networking can also be split into separate devices. In a preferred embodiment, a foreign registration agent handles session control and registration traffic with the home registration agent, and a foreign tunneling agent provides packet capsulation/decapsulation and routing services for the mobile node and exchanging data traffic with the home tunneling agent.

摘要： A system for live TV transmission over IP networks incorporates a content encoder receiving live TV broadcast and converting to RTP packets for multicast streaming. A streaming server receives the multicast RTP packets from the content encoder and converts the multicast stream to a unicast stream. The streaming server is also responsive to RTSP commands for trick mode operation. A settop box is connected through an IP network for receiving multicast RTP packets from the content encoder and generating RTSP commands for trick mode operation, the setup box issuing a leave multicast group signal upon issuing a trick mode command and receiving unicast transmission of RTP packets from the streaming server controllable by the trick mode commands.

摘要： In an end to end fully internet protocol (IP) enabled network, a dynamic IP address space is used to address mobile hosts in order to facilitate mobility management. The network includes a wireless mobile network having a plurality of base stations each being associated with a portion of the dynamic IP address space. The base stations are operative to allocate dynamic IP addresses from the associated portion of the dynamic IP address space for each authenticated mobile host. Each of the base stations provides translation between the dynamic IP address space and a permanent IP address space so that the dynamic IP address space is transparent from the point of view of the mobile hosts. A gateway provides communicative coupling between the backbone of the wireless mobile network and a wire lined IP network. The gateway also provides translation between the dynamic IP address space and the permanent IP address space.

摘要： Methods for seamless transfer of media traffic for roaming mobile terminals during hard handoffs from one base station system to another are described. In one embodiment, a base station controller forwards media traffic after handoff occurs to a second base station controller where the mobile terminal is currently registered. The second base station controller listens for media traffic from the first base station controller on one port and for traffic from the remote equipment on a second port. When traffic starts to arrive on the second port, the first port is released.
