Abstract: A method is provided for scheduling data transmission in a Multiple-Input Multiple-Output (MIMO) Orthogonal Frequency Division Multiplexing (OFDM) system. The MIMO-OFDM system may comprise at least one MIMO-OFDM transmitter and at least one MIMO-OFDM receiver. Feedback from one or more receivers may be used by a transmitter to improve quality, capacity, and scheduling in MIMO-OFDM communication systems. The method may comprise generating or receiving information pertaining to a MIMO channel metric and information pertaining to a Channel Quality Indicator (CQI) in respect of a transmitted signal; and sending a next transmission to a receiver using a MIMO mode selected in accordance with the information pertaining to the MIMO channel metric, and an adaptive coding and modulation selected in accordance with the information pertaining to the CQI.

Abstract: The performance of a voice conference using a packet-based conference bridge can be improved with a number of modifications. In one modification, the conference bridge receives speech indication signals from the individual packet-based terminals within the voice conference, these speech indication signals then being used by the conference bridge to select the talkers within the voice conference. This removes the need for speech detection techniques within the conference bridge, hence decreasing the required processing power and the latency within the conference bridge. In another modification, the conference bridge sends addressing control signals to the individual packet-based terminals selected as talkers, these addressing control signals directing the terminals selected as talkers to directly transmit their voice data packets to the other terminals within the voice conference. This direct transmission of voice data packets can reduce transcoding and latency within the network.

Abstract: A packet-based multimedia service is provided to a terminal in a network. A packet signaling connection is established between the terminal and the network. Signaling information for the multimedia service is transferred via the packet signaling connection using Session Initiation Protocol (SIP) or a similar protocol. A circuit bearer connection is also established with the terminal. Data for the multimedia service is transferred via the circuit bearer connection. This allows the data to be carried across networks which do not support the required QoS functionality for the packet-based service, or which cannot efficiently carry packet-based data. The circuit bearer connection can be established by a network entity or by the terminal. The circuit bearer can be interworked to a packet-switched bearer at some point in the network, such as at a gateway, so as to provide a remote party with the appearance that a fully packet-switched connection is being used.

Abstract: A system, method, and network interface obscures the existence of data encryption in a communication network is provided. A set of characters is generated by using a set of encryption keys as an input to a pseudo-random function. Each character corresponds to an index value. The encrypted data is divided into a plurality of parts. Each part is sectioned into a plurality of groups. Each group of the plurality of groups is encoded by mapping the group to a character in the set of characters according to its corresponding index value. The mapped characters are transmitted through the communication network.

Abstract: A wireless communication method and system using virtual MIMO (“V-MIMO”) are provided. Post processing signal to interference and noise ratios (“SINR”) for a plurality of signals corresponding to a plurality of mobile terminals arranged as a V-MIMO group are estimated. The one of the plurality of mobile terminals having the highest post processing SINR is selected. Wireless communication for the selected mobile terminal is scheduled. The signal corresponding to the selected mobile terminal is cancelled. Post processing signal to interference and noise ratios (“SINR”) for the signals corresponding to the remaining mobile terminals is re-estimated. The one of the remaining mobile terminals having the highest post processing SINR is selected. Wireless communication for the selected remaining mobile terminal is scheduled.

Abstract: In a bearer-independent core network, the switching and transport of the bearer streams is separated from the processing of call sessions that control the bearer streams. The switching and transport of the bearer streams is executed by media gateways and packet switches in the switching and transport layer of the network. The processing of calls sessions that control the bearer streams is executed by call servers in the call control layer of the network. The switching and transport layer of the network may be implemented using ATM or IP technology. In order to redirect the signaling links to a backup call server, a signaling gateway is used. Each media gateway includes a signaling gateway function. The signaling gateways redirect the signaling links by encapsulating each signaling message in a new packet in one embodiment.

Abstract: The present invention provides a system, method, and apparatus for managing the calling-party identification information offered to called parties. Accordingly, a caller can designate the Caller ID information to the called party based on the context of the call (e.g. the role of the caller) rather than the terminal used. Typically the calling party does this by selecting which of multiple values they wish to have sent with the call request. It is beneficial to implement such a mechanism in a secure manner—the ability to employ a different calling-number or calling-name ID should be restricted to properly-authorized and authenticated persons—in order to ensure the quality of this information. Accordingly, preferred embodiments include an authentication mechanism for verifying the calling party information is authentic.

Abstract: A method and system are provided having an uplink control structure and a pilot signal having minimal signal overhead for providing channel estimation and data demodulation in a wireless communication network. The uplink control structures enable mobile terminals to communicate with corresponding base stations to perform various functions including obtaining initial system access, submitting a bandwidth request, triggering a continuation of negotiated service, or providing a proposed allocation re-configuration header. A dedicated random access channel is provided to communicatively couple the base station and the mobile terminal so that the mobile terminal can select a random access signaling identification. A resource request is received at the base station to uplink resource information from the mobile terminal and an initial access information request is received from the mobile terminal to configure the base station connection.

Abstract: A module hot swap circuit includes a low voltage-drop rectifier adapted to receive either positive or negative voltages of different absolute values. The rectifier is coupled to a power manager that provides dual startup/shutdown voltage thresholds and inrush current limiting. A detector prevents reverse current flow allowing the module to hold up during input voltage drop-outs.

Abstract: A virtual private network is provided across a Provider Link State Bridging (PLSB) network between a first node connected to a private LAN and a second node connected to a roaming device. The roaming device is authenticated. A successful authentication results in a Service Identifier for the VPN being sent to the second node. Connectivity between members of the VPN service instance is maintained as part of the PLSB Link State process for forwarding table maintenance, rather than by any form of explicit signalling. A single Customer Virtual Bridge/Virtual Switch Instance can be located at the first node to provide point-to-point connectivity to each roaming device. A virtual Residential Gateway function can be combined with the Customer Virtual Bridge/Virtual Switch Instance.

Abstract: The present invention provides a technique for automatically establishing a virtual circuit from one edge device to another through a core network. The virtual circuit may comprise one or more pseudowire segments. These pseudowire segments extend between adjacent edge and core devices within the core network. Pseudowire segments through the core network are automatically stitched together as a setup message is forwarded from a first edge device to a second edge device through the core network. A virtual circuit is established in one direction, and packets are forwarded in an opposite direction. With the present invention, a virtual circuit comprising any number of pseudowire segments, as well as two attachment circuits, may be established in an automatic and efficient manner upon being initiated by the first edge device.

Abstract: A method and apparatus for interfacing a customer with a call center allows information obtained from a Radio Frequency Identification (RFID) tag to be transmitted to the call center to provide additional information about the customer and allow the session to be routed within the call center more accurately. The call center may be accessed by telephone, computer, or via another type of customer premises equipment over a voice or data network. The RFID tag may be an identification tag provided to the customer for access to the call center or may be a tag associated with the customer and not specific to the call center. The call center may route calls based on routing information contained in the RFID tag information, customer identity and previous sessions with that customer, personal and demographic information and statistical support records for other sessions involving customers with similar personal and demographic information, and according to agent statistical support records.

Abstract: The present invention provides an architecture for translating closed captioning text originally provided with a video program from one language to another and presenting the translated closed captioning text with the video program to a viewer. As such, the viewers are able to receive the closed captioning text in languages other than that used for the closed captioning originally provided with the video program. The original closed captioning text may be translated from one language to another by a centralized closed captioning processor, such that the customer equipment for various subscribers can take advantage of centralized translation services. Once the original closed captioning text is translated, the translated closed captioning text may be delivered to the customer equipment in different ways.

Abstract: The present invention allows mobile terminals to receive location-based information upon entering a local wireless zone established by an access point. The access point includes or is associated with one or more servers, which may provide the location-based information and control access. The local wireless zone is a limited area in which communications between the access point and the mobile terminal are possible. Once the mobile terminal enters into one or more local wireless zones, the presence of the mobile terminal in the local wireless zone is detected. Once detected, the mobile terminal is afforded access to a server on which the location-based information is stored. The server is associated with the local wireless zone.

Abstract: Ethernet OAM MEPs are automatically configured in a link state protocol controlled Ethernet network. A node operating in the link state protocol controlled Ethernet network receives a Link State PDU (LSP) containing a TLV having a MEP associated with the Ethernet MAC node ID of a second node in the link state protocol controlled Ethernet network, where the path between the first and second node includes a plurality of links. The node updates a forwarding table to indicate an association between the MEP ID and a Ethernet MAC node ID of the second node. An Ethernet OAM maintenance endpoint is produced in a link state protocol controlled Ethernet network by hashing a Sys-ID to produce a MEP; storing the MEP in a TLV; and forwarding the TLV over the link state protocol controlled Ethernet network in an LSP.

Abstract: Virtual routers that abstract photonic sub-domains are provided for GMPLS networks. A virtual router uses a link viability matrix to keep track of the set of viable connections between inputs and outputs of a photonic sub-domain. A virtual router may receive RSVP-TE signaling messages and either allocate a working input to output link pair or, if explicitly signaled, verify that the requested link is currently viable. A virtual router also advertises, in its link state updates, the current set of possible outputs for any input link. Shortest path computations can be implemented utilizing virtual routers by modifying a topology graph in accordance with the link viability matrix of the virtual router.

Abstract: A system for scheduling data for transmission in a communication network includes a credit distributor and a transmit selector. The communication network includes a plurality of children. The transmit selector is communicatively coupled to the credit distributor. The credit distributor operates to grant credits to at least one of eligible children and children having a negative credit count. Each credit is redeemable for data transmission. The credit distributor further operates to affect fairness between children with ratios of granted credits, maintain a credit balance representing a total amount of undistributed credits available, and deduct the granted credits from the credit balance. The transmit selector operates to select at least one eligible and enabled child for dequeuing, bias selection of the eligible and enabled child to an eligible and enabled child with positive credits, and add credits to the credit balance corresponding to an amount of data selected for dequeuing.
