Abstract: According to specific embodiments of the present invention, a standardized interface is provided for enabling controlled communication between MAC and PHY devices of an access network. In one embodiment, a vendor independent interface is described which may be implemented between a DOCSIS MAC layer and a DOCSIS PHY layer of a DOCSIS enabled data network, in order to enable any DOCSIS MAC and DOCSIS PHY devices (which may be from different vendors) to communicate with each other. Using the standardized interface, component manufacturers are able to combine different MAC and PHY devices from different vendors, thereby facilitating price and value competition between vendors. The standardized interface technique of the present invention may be extensible in ways which allow multiple PHY devices to share the same interface.

Abstract: When congestion occurs in a RAN in a cell phone VoIP service, calls using the congested device are detected to permit generation of a restriction in call by call units. The congested device notifies call connection data passing through it to a PDSN, the PDSN finds the IP address of the terminal using the target connection, and notifies a CSCF as a restriction target terminal. The CSCF, in call connection processing, determines whether the calling/called sending/receiving user is the restriction target, and if so, determines whether or not the call should be connected with priority from subscriber data.

The deskew FIFO module includes four deskew FIFO buffers for respectively holding the Ethernet PHY signals of the duplex channels, wherein the Ethernet PHY signals of the duplex channels are respectively retrieved from the deskew FIFO buffers for further processing through read points of the deskew FIFO buffers.

Abstract: A service provider system connects to systems associated with a group of business-partners. Each of the business-partners sells services, of an extensible set of services provided by the service provider system, to its customers. The service provider system provides a common interface via which the business-partner systems can request one or more services from the extensible set of services. The service provider system exposes subsets of the common interface to each of the business-partner systems by controlling access to the extensible set of services by the business-partner systems.

Abstract: Methods are provided for transitioning between SIP and MIP. Mobile devices, upon detecting a new system, automatically attempt a MIP session to avoid the default position of SIP. A history is maintained of systems visited, and for systems that did not support MIP in the past, a MIP session is not attempted, but rather SIP is initiated from the start.

Abstract: A multistage interconnect network (MIN) capable of supporting massive parallel processing, including point-to-point and multicast communications between processor modules (PMs) which are connected to the input and output ports of the network. The network is built using interconnected switch nodes arranged in 2 [logb N] stages, wherein b is the number of switch node input/output ports, N is the number of network input/output ports and [logb N] indicates a ceiling function providing the smallest integer not less than logb N. The additional stages provide additional paths between network input ports and network output ports, thereby enhancing fault tolerance and lessening contention.

Abstract: A packet forwarding apparatus 200 transmits an inputted packet A to a first output port that is one of a plurality of output ports and transmits a dummy packet A storing the packet length of packet A to the other output port. A shaping unit 100-1 corresponding to the first output port uses the packet length of the packet A and a shaping unit 100-2 corresponding to the port other than the first output port uses a packet length in the dummy packet A so as to control the bandwidth of the packet A to be transmitted, thus controlling the total bandwidth of the packet A.

Abstract: A communications system that supports multimedia components is easily adapted to existing network elements. Voice components arriving at or coming from a user having multimedia capabilities are referred from a telephony server serving the user to a multimedia server. A determination is made as to whether the other party supports multimedia capabilities. If that determination is negative, the component is passed back to the telephony server with an indication that the session is coming from the multimedia server to avoid an infinite loop. If the determination is positive, a parallel multimedia component is established between the parties while the multimedia server remains aware of the bearer path.

Abstract: When any communication port receives a packet from a network, it transmits the packet to a relay processing section. The relay processing section identifies a relay processing section of a transfer destination according to destination information included in the packet to transmit the packet to a packet switch section. When the relay processing section of the transfer destination is a working relay processing section, the packet switch section transfers the packet to the working relay processing section and a protection relay processing section.

Abstract: The invention relates to a method for transmitting data for a multimedia broadcast/multicast service (MBMS) from a radio access network of a cellular communication network via a radio interface to mobile terminals located in a radio cell supplied by said radio access network. The radio access network transmits paging messages on a common control channel. It is proposed that a dedicated channel is employed for transmitting the MBMS data, which dedicated channel is allocated in a way that the mobile terminals are able to receive simultaneously paging messages and the MBMS data. The invention relates equally to a corresponding network entity, mobile terminal and communication system.

Abstract: Voice over Internet Protocol (VoIP) calls received in a Hybrid Fiber Coax (HFC) network (12) maintained by a provider of HFC VoIP telephony services are advantageously translated into a Time-Division Multiplex (TDM) format by an Internet Protocol Device Terminal (IPDT) (26) in the HFC network. Once translated into a TDM format, the call passes to the Public Switched Telephone Network (PSTN) (28) for call processing to afford the call features subscribed to by the called party, such as caller-ID and call waiting. Once processed, the PSTN routes the call to the destination. Likewise, a call destined for an HFC VoIP customer can be processed within the PSTN to afford the call features subscribed to by the HFC VoIP customer. In this way, the HFC VoIP telephony service can offer full-featured VoIP cable telephony without the need to perform call processing in its own network.
