  • Patent number: 8477864
    Abstract: A MIMO transmission scheme is provided which provides some advantages of the Alamouti code but which can be adapted so as to provide enhanced performance for a given amount of antenna correlation. A block of complex scalar input symbols is mapped to a block-code matrix which is transmitted as a spacetime signal matrix from an array of two or more antennas. The block-code matrix is assembled by combining input data with specified dispersion matrices. Each of the dispersion matrices is determined, in part, by an adjustable parameter which relates to a degree of beam-forming behavior by the transmission antenna array.

  • Patent number: 8477760
    Abstract: A method and apparatus for performing a active packet bundling in a VoIP (Voice over Internet Protocol) based on a measure of voice concealability of one or more speech packets to be transmitted. Voice concealability is a property of a speech packet which indicates the likelihood that a given speech segment will meet the “quasi-stationary” (QS) behavior assumed by conventional Packet Loss Concealment (PLC) algorithms used to compensate for transmission loss of speech packets. By ensuring that only well-concealed frames are delayed for bundling, it is more likely that the receiver will run the PLC algorithm when it is most effective (i.e., when it is likely to perform well at reconstructing the missing speech frame), rather than when it is more likely to be ineffective. This allows for a reduction in bandwidth while minimizing any potential negative impact on quality.

  • Patent number: 8477737
    Abstract: A method of uplink carrier handoff in a multiple carrier communication system may include receiving a measurement report from a mobile providing information regarding path loss as measured at the mobile for one of the multiple carriers on the downlink. A serving carrier may be the carrier over which the mobile communicates on the uplink. An instruction may be selectively sent to the mobile to handoff to a non-serving one of the multiple carriers depending on whether a threshold requirement has been met. The meeting of the threshold requirement may be based on the received measurement report and the serving carrier of the mobile. Each of the multiple carriers may have an associated threshold requirement.

  • Patent number: 8479290
    Abstract: A method of remotely treating malicious mobile terminals connected to a mobile communications network. In one embodiment, when a malicious mobile terminal is detected by the intrusion-detection services of the network, the network changes the subscriber profile associated with the mobile terminal to operate the latter in a quarantine mode. The packet-switched subsystem of the network then links the quarantined mobile terminal to a remediation manager. The remediation manager remotely treats the mobile terminal, e.g., to repair or reinstall any corrupted software, terminate any active malicious processes, delete or quarantine any malware, and restore the operating system, configuration, and/or memory of the mobile terminal to a clean operational state. After the treatment, the network reverts the subscriber profile back to the initial state and removes the mobile terminal from the quarantine.

  • Patent number: 8478135
    Abstract: An optical receiver includes a two-stage constant modulus algorithm (CMA) equalizer. The first stage is a modified version of a CMA equalizer and the second stage is a conventional CMA equalizer. The first stage may be made up of four sub-equalizers, of which only two of the sub-equalizers are independent, i.e., uncorrelated to each other. This first stage equalizer compensates for polarization-mode dispersion (PMD). The second stage equalizer is a conventional CMA equalizer made up of four sub-equalizers that are adjusted independently. This second stage equalizer may compensate for polarization-dependent loss (PDL). The receiver includes a first processor that determines PMD information based on a plurality of transfer function parameters of the modified CMA equalization of the first stage equalizer and the modified-equalized output and a second processor that determines PDL based on a plurality of transfer function parameters of the CMA equalization of the second stage equalizer.

  • Patent number: 8477780
    Abstract: Processing packet information using an array of processing elements involves performing search-independent processing on packet information in parallel with a search of a first stage memory unit and then using the processed information and the result from the search of the first stage memory unit to generate search information for a search of a second stage memory unit. The search-independent processing of packet information in parallel with search operations can be repeated at each stage of the array. By performing search-independent processing of packet information in parallel with search operations instead of serially, latency that is contributed from the relatively slow search operations is reduced.

  • Patent number: 8477912
    Abstract: Communication networks and associated methods are disclosed that provide a content sharing service through multimedia ringback tones. The communication network comprises a network node and a multimedia ringback system. The network node receives a call from a calling party to a subscriber of the content sharing service, and routes the call to the multimedia ringback system. The multimedia ringback system identifies a multimedia ringback tone for the call where the multimedia ringback tone includes a message prompting the calling party to share content of the subscriber, and provides the multimedia ringback tone to the calling party. The multimedia ringback system then receives a request for the content indicated in the multimedia ringback tone from the calling party, and initiates the transfer of the content to the calling party responsive to the request.

  • Patent number: 8472444
    Abstract: A method and apparatus for offloading data traffic routing from one NI (network interface) to another. The NI receives data traffic, and that portion of the data traffic that must be L3 routed is passed to the CPU of the NI though a token bucket meter or equivalent metering device that selectively designates a portion of the routing traffic to another NI for routing. The portion of the traffic designated corresponds to the capacity of the CPU and offloading a portion of the data traffic helps to reduce the number of packets that are discarded when a CPU is overloaded. The threshold for determining when and in what quantity the data traffic should be offloaded is either statically or dynamically set, and in the latter case may be updated automatically when traffic levels and, in some implementations, other considerations require.
