  • Patent number: 8861404
    Abstract: IMS networks and methods are disclosed for storing information on the access network of a user in a subscriber profile for the user. When a communication device of a user attempts to register with an IMS network, a P-CSCF receives a register request message from the communication device, and identifies access network information for the user. The P-CSCF then transmits another register request message to an S-CSCF that includes the access network information, and the S-CSCF in turn forwards the access network information to an HSS. The HSS then stores the access network information in the subscriber profile for the user. Nodes in the IMS network that retrieve the subscriber profile may acquire the access network information to provide services based on the access network information.

  • Patent number: 8830834
    Abstract: Network topology independent service deployment techniques, referred to as overlay-based packet steering techniques, are provided. In one example, a server destined packet is intercepted by an in-path network device enabled as a service classifier. The service classifier encapsulates the packet and inserts the packet into a service path to a service virtualization endpoint front ending one or more service nodes. In other words, the service virtualization endpoint receives the service-directed packet on an overlay-based service path. The service-directed packet includes a service header and a service overlay tunnel encapsulation. The service virtualization endpoint inspects the service header in the service-directed packet to identify a first service node to which the service-directed packet should be forwarded and, based on the inspection, forwards the service-directed packet, on the overlay-based service path, to the first service node.

  • Patent number: 8660122
    Abstract: A communication technique facilitates transmission of low rate traffic over communication nodes. The nodes may be, for example, MoCA nodes. The communication happens while keeping the nodes in ultra low power mode. Accordingly, the technique increases the communication capabilities and coverage of networked nodes without impacting the overall power consumption budget. In one implementation, the technique includes encapsulating a datagram into a datagram information element, appending the datagram information element to a discovery request message, and sending the discovery request message to a network controller. The network controller extracts the datagram information element and forwards it (e.g., by broadcasting) to ultra low powered nodes, for example in an admission control frame.

  • Patent number: 8396934
    Abstract: The goal of the present invention is to improve the useful data efficiency and reliability in the use of commercially available ETHERNET controllers, in a distributed real time computer system, by a number of node computers communicating via one or more communication channels by means of TT ETHERNET messages. To achieve this goal, a distinction is made between the node computer send time (KNSZPKT) and the network send time (NWSZPKT) of a message. The KNSZPKT must wait for the NWSZPKT, so that under all circumstances, the start of the message has arrived in the TT star coupler at the NWSZPKT, interpreted by the clock in the TT star coupler. The TT star coupler is modified, so that a message arriving from a node computer is delayed in an intelligent port of the TT star coupler until the NWSZPKT can send it precisely at the NWSZPKT into the TT network.

The service platform transfers a prompt message over the call, collects caller-entered information from a caller over the call in response to the prompt message, and transfers the caller-entered information to a call processing system. The call processing system transfers the caller-entered information to a destination processor, processes a destination routing code from the destination processor to determine a destination routing instruction, and transfers the destination routing instruction to the switching system. The switching system routes the call to a destination in response to the destination routing instruction.

  • Patent number: 7801024
    Abstract: A system and method is disclosed that assures component circuits transported in aggregated circuits restore correctly after an aggregated circuit fault. The system and method implements component circuit tail segment integrity checks whenever an aggregated circuit is restored in a higher level of a network hierarchy. Switches at both ends of an aggregated circuit perform circuit integrity checks of the tail segments of every component circuit. A failure of the component circuit integrity check on any component circuit causes that component circuit to be released and restored end-to-end.

  • Patent number: 7787483
    Abstract: In a network for digital data packet transmission, reception quality of received data packets is sensed (111) by a remote terminal (101). Thereupon, a bit string indicative for the sensed reception quality is generated (112). This bit string or a compressed version of this bit string is transferred (114) in real-time over a management channel to a first central processing unit (121) in a network node (102) where the bit string is compacted or processed. By processing the bit string, the first central processing unit (121) may determine impulse noise characteristics. Alternatively, the bit string or a compressed or compacted version thereof may be forwarded to a second central processing unit (131) in a network manager (103) that processes the bit string and determines impulse noise characteristics.

  • Patent number: 7720382
    Abstract: A system and method are disclosed for time-domain wavelength interleaved networking that reduce the need for complex time-slot scheduling and reduce the routing complexity. Substantially all communications in the time-domain wavelength interleaved network pass through a hub node. In addition, interior nodes in the time-domain wavelength interleaved network will forward substantially all communications received from the hub node that are destined for another node on all branches outward from the hub node. The central hub node can impose a timing reference. Thus, the transmission and reception of a message can be synchronized such that a message sent in a time-slot k by a node Ni will be received by a node Nj in the time-slot k. Further, the hub node can recover from a link failure by shifting transmission times of all nodes that are separated from the hub node by the failed link.

  • Patent number: 7671249
    Abstract: In the operation input device of the prior art, the input of a position and the input of an attitude are mixed up and both the position and attitude may be changed by the result of the input of a change in attitude. Therefore, the intention of an operator cannot be reflected accurately. To solve the above problem, an operation input device of the present invention has a first movement detection unit for detecting the position and attitude of a first operation input unit and a second movement detection unit, connected to the first movement detection unit, for detecting the position and attitude of a second operation input unit to separate a part for inputting a position from a part for inputting an attitude.

  • Patent number: 7664134
    Abstract: In a network having nodes that operate according to a protocol that defines a node as being in an idle mode when the node is not transmitting or receiving a packet, a method of communicating between nodes during the idle mode. A message formatted according to the protocol is generated. The message is different from messages predefined by the protocol for transmission during the idle mode. For example, the message can comprise a first portion that reports a link status condition. The message can further comprise a second portion that reports a cause of the link status condition. The message is transmitted from a first node of the network when the first node is in the idle mode. The message is received at a second node of the network when the second node is in the idle mode.

  • Patent number: 7653081
    Abstract: A system for transporting public switched network (PSTN) terminated signaling across an Internet protocol (IP) network includes a gateway between the PSTN and the IP network. The gateway receives a telephony signaling message from the PSTN and determines if the telephony signaling message maps to an IP signaling message. If the telephony signaling message does not map to an IP signaling message, the gateway packages the telephony signaling message in a special IP signaling message for transport over the IP network. If the gateway receives a special IP signaling special message, the gateway unpackages the telephony signaling message from the special message for transport over the PSTN. If the gateway receives DTMF signals from the PSTN, the gateway translates the DTMF signals to digits and packages the digits in a special IP signaling message for transport over the IP network. The gateway also packages the DTMF signals in an IP media transport protocol message for transport over the IP network.

  • Patent number: 7633932
    Abstract: A method is disclosed that enables accelerating the removal from service of a signal processor at a media gateway. In accordance with the illustrative embodiment of the present invention, the media gateway receives an indication to remove one of its digital signal processors from service. Instead of waiting for all of the calls that are using the signal processor to come to an end, the media gateway proactively moves the packet streams from the signal processor to one or more other signal processors resident at the gateway. Advantageously, an effort is made to avoid having to inform the corresponding media gateway controller of the move, thereby minimizing any discontinuity in each moved packet stream.
