  • Patent number: 7496030
    Abstract: A technique for managing loops between network devices such as customer and carrier edge devices involves monitoring the MAC moves that occur at a device to detect the existence of a loop and initiating a loop protection action if the MAC moves indicate that a loop exists. The number of MAC moves that indicates the existence of a loop is user programmable and pre-established in the device configuration. The number of MAC moves can be expressed as a MAC move threshold, which is defined in terms of, for example, a MAC move rate or a number of MAC moves. Typically, the loop protection action that is initiated in response to a detected loop involves blocking the flow of the looping packets at the corresponding device.

  • Patent number: 7496066
    Abstract: The present invention provides a method and an apparatus for managing mobility of a wireless communication device across a first and a second access node in a common administrational area of a network. The method comprises using the first access node to assign a temporary identification to the wireless communication device, causing the second access node to identify the first access node from which the temporary identification originates and hiding the mobility of the wireless communication device from the network when routing traffic to a serving access node of the first and second access nodes based on the identified first access node and the temporary identification. In one embodiment, use of software at these access nodes may enable deploying of a centralized logical functionality instead of centralized physical nodes.

  • Patent number: 7460785
    Abstract: An optical performance monitor (OPM), e.g., for use in an optical network. The OPM may be configured to characterize one or more impairments in an optical signal modulated with data. The OPM has an optical autocorrelator configured to sample the autocorrelation function of the optical signal, e.g., using two-photon absorption. Autocorrelation points at various bit delays independently or in combination with average optical power may be used to detect and/or quantify one or more of the following: loss of data modulation, signal contrast, pulse broadening, peak power fluctuations, timing jitter, and deviations from the pseudo-random character of data. In addition, the OPM may be configured to perform Fourier transformation based on the autocorrelation points to obtain corresponding spectral components. The spectral components may be used to detect and/or quantify one or more of chromatic dispersion, polarization mode dispersion, and misalignment of a pulse carver and data modulator.

  • Patent number: 7460858
    Abstract: In order to reduce the traffic on the paging channel, the system for reducing paging channel occupancy for message waiting indication in mobile switching centers allows the Message Waiting Notification process to determine a last zone in which the Mobile Subscriber was located and only transmit the Message Waiting Indication to the cells within that zone. This eliminates message transmission on the paging channel of cells which are not likely to have the Mobile Subscriber Station residing in their service area. Multiple retries can be attempted and if the last retry is being activated, the paging can be extended to cover all zones in the Mobile Switching Center. The sharing of information about when a mobile has responded to a message waiting count between the Serving MSC and the Home MSC also reduces the paging channel occupancy.
