| 20120002543 | METHOD AND APPARATUS FOR HANDLING TRAFFIC IN A DATA COMMUNICATION NETWORK - A method and apparatus for offloading data traffic routing from one NI (network interface) to another.

After the treatment, the network reverts the subscriber profile back to the initial state and removes the mobile terminal from the quarantine. | 12-22-2011 |
| 20110310736 | Method And System For Handling Traffic In A Data Communication Network - A method and system for offloading data traffic routing from one NI (network interface) to another in a multi-NI platform. When an NI determines that offloading of data traffic should occur, it disables routing at the incoming port or ports on which L3 traffic may be received, and reconfigures an L2 table to indicate that traffic addressed to a router MAC address should not be routed, but instead bridged to the other NI. This bridging is preferably done using an inter-NI link that is dedicated for communication between two or more NIs in the multi-Ni platform. The determination to offload traffic may, in some embodiments, be made as part of an initialization sequence and offloading is used until synchronization of the NI has been completed to a pre-determined point, at which time a determination is made to terminate offloading and routing from the NI is re-enabled. | 12-22-2011 |
| 20110307538 | NETWORK BASED PEER-TO-PEER TRAFFIC OPTIMIZATION - A peer-to-peer accelerator system is disclosed for reducing reverse link bandwidth bottlenecking of peer-to-peer content transfers. The peer-to-peer accelerator system contains a peer-to-peer proxy which resides in the core of the network.

| 20110217043 | ITERATIVE CARRIER-PHASE ESTIMATION AND DATA RECOVERY FOR COHERENT OPTICAL RECEIVERS - In one embodiment, a coherent optical receiver has an optical detector coupled to a digital processor. The optical detector mixes a received modulated optical signal with a local-oscillator signal to produce a digital measure of the modulated optical signal. The digital processor processes the digital measure using a primary carrier- and data-recovery (CDR) stage and one or more secondary CDR stages serially connected to one another. The processing performed in each secondary CDR stage is decision-directed and uses the symbol estimate generated by the preceding CDR stage to obtain a respective estimate of the carrier-phase offset and a respective symbol estimate. Since each subsequent CDR stage typically improves the accuracies of its estimates compared to those of the preceding CDR stage(s), the receiver has a lower bit-error rate than a receiver employing a single CDR stage. | 09-08-2011 |

During an FCC transaction, the subscriber interface device, such as a set-top box (STB), can determine how long it can wait to join the multicast stream of the new channel before a gap can be predicted to occur in the handover from the FCC unicast to the multicast.

| 20100177880 | CONFERENCE-CALL PARTICIPANT-INFORMATION PROCESSING - In one embodiment, a telecommunication device for Internet-based conference calling with one or more similar telecommunication devices. The telecommunication device is used by a plurality of co-located participants, each participant having an individually identifiable microphone. The telecommunication device accesses a database correlating each individually identifiable microphone to participant ID and information. During the conference-call setup, the similar telecommunication devices exchange participant IDs and corresponding information. The conference-call audio content is then exchanged using RTP packets, where the telecommunication devices generate RTP packets containing the participant IDs of participants contributing to the content of each RTP packet. Receiving telecommunication devices then display corresponding participant information when playing the audio content of received RTP packets to identify current speakers. Individual, identifiable microphones improve the audio quality received by remote participants and permit the automatic exchange and display of the current participants and the current speakers. | 07-15-2010 |
