  • Patent number: 7391826
    Abstract: A method of decoding is provided comprising processing iterations. In each processing iteration, there is a first Max-Log-MAP decoding operation giving rise to a systematic error due to the Max-Log approximation, and a first weighting operation to weight extrinsic information from the first decoding operation to be applied as a priori information to the second Max-Log-MAP decoding operation. This is followed by a second Max-Log-MAP decoding operation, also giving rise to a systematic error due to the Max-Log approximation, and a second weighting operation to weight extrinsic information from the second decoding to be applied as a priori information to the first Max-Log-MAP decoding of the next iteration. The weights are applied to compensate for the systematic error due to the Max-Log approximation made in the last Max-Log-MAP decoding operation.

  • Patent number: 7392459
    Abstract: At the receiver in a wireless communications system, the likelihood of a false CRC pass that can occur when a weak received signal produces an all ZERO output from a convolutional or a turbo decoder is minimized. To prevent an all ZERO output, a convolutional decoder selects from among those determined equally most likely transmitted sequences of bits in a data block one that has a weight greater than the one having the minimum weight. A turbo decoder selects a ONE rather than a ZERO as the value of a transmitted bit in a data block when for that bit a bit value of a ZERO and a ONE are determined to be equally likely.

  • Patent number: 7392520
    Abstract: Method for upgrading software in a network bridge that is part of a VLAN includes sending notification to other bridges of the VLAN that the bridge is scheduled for upgrading; suspending VLAN registration and membership information in the other bridges while upgrading the bridge; restoring a state of the updated bridge and sending notification to the other bridges that the upgrading has been completed. As a result of the notification, the other bridges do not expect additional messages from the upgrading bridge. The step of restoring a state of the bridge includes synchronizing a GVRP protocol running within the network to a current VLAN membership table. Apparatus includes a forwarding plane adapted to store VLAN membership information and a control plane adapted for issuing and executing instructions that control registration and de-registration of one or more ports of the bridge according to the VLAN membership information and the presented method.

  • Patent number: 7391755
    Abstract: A method for conveying signaling information of a communication system that uses MIMO antenna systems. To enable a relatively larger amount of information to be conveyed over the communication system and thus exploit the use of the MIMO antenna system, forward link signaling channels are provided where such channels contain swapping information that allow the communication system to retransmit traffic information using any one of the antenna elements of a MIMO system. The forward link signaling channels also contain channel assignment information that indicate which particular groups of channels are available for use by particular users of the communication system.

  • Patent number: 7392035
    Abstract: Consolidated billing in a wireless network is achieved by employing a processing node having storage capabilities for facilitating service creation and/or negotiation, and billing for those services in a wireless network, by associating user information and/or service information with network information. User information, service information, and network information, and their associated billing information, are provided periodically and dynamically into the storage. Using the processing node, user information and/or service information are associated with network information without having to access various network elements located throughout the network, to facilitate service creation and/or negotiation, and billing of services, to thus minimize network processing and network resources.

  • Patent number: 7392055
    Abstract: Resource allocation in a wireless data system determines a load condition of the system and adapts a target quality of service (QoS) characteristic, accordingly. Data transmission parameters may be assigned, or adapted, for the wireless units based on the adapted target QoS characteristics. Resources are allocated to data transmissions between wireless units based on these parameters. As the system load decreases, the target QoS characteristic is adapted so that more resources will be allocated to the wireless unit, and the QoS will improve. The adapted QoS threshold may be a data error rate or target fill efficiency for each wireless unit.

  • Patent number: 7388947
    Abstract: Data generated at a telecommunications network switching node is selectively delivered to one or more data receiving device (e.g., data “collection box”) connected to the network, and command and control signaling is transmitted from the data receiving device to the switching node. This bi-directional communication is carried out in a manner compatible with voice grade lines. In an exemplary application, call identifying information, referred to in the TIA/EIA Standard as CDC (Call Data Channel) Messages, is delivered from an Intercept Access Point (IAP) switch that provides telephone service to a subject of an authorized surveillance order, to a law enforcement data collection box, utilizing Frequency Shift Keying (FSK) signals. Control signals are sent from the data collection box to the IAP switch utilizing Dual Tone Multi-Frequency (DTMF) signaling.

  • Patent number: 7388430
    Abstract: In one embodiment of the present invention, a weight vector is generated based on a pre-distorted input signal and an output signal of an amplifier using a computation reduction technique. The computation reduction technique decomposes a number of multiplication operations between complex numbers such that a number of multiplications and a number of additions to generate the weight vector is reduced as compared to if the number of multiplication operations between complex numbers was not decomposed. An input signal for input to an amplifier is pre-distorted based on the generated weight vector.

  • Patent number: 7388838
    Abstract: An advance over the prior art is achieved through an efficient method for an admission control algorithm and a scheduling mechanism that complement each other in providing the following three classes of service. A first class of service is termed Class 1 where users specify a nominal amount of bandwidth desired. A second, lower tier service class is termed Class 2, wherein users specify a nominal and minimum amount of bandwidth desired when entering into a network connection. A third server class is Class 3, where Class 3 users are treated as best effort users. For Class 1 users the methodology of the present invention provides a guaranteed nominal amount of bandwidth. The admission control procedure ensures that Class 1 users are admitted only if resources exist to satisfy the nominal bandwidth requirements of the Class 1 users. Class 2 users are admitted if resources exist to satisfy the minimum bandwidth requirements of the user.

  • Patent number: 7386320
    Abstract: In a wireless communications system, multicast messages are transported to groups of wireless terminals by employing a common control channel to transmit a multicast paging message indicating that multicast traffic data is to be transmitted to a particular group of wireless terminals. In an embodiment of the invention, the essential information transmitted in the common control channel is the identifier of the group of wireless terminals intended to receive the multicast traffic data and the location of a traffic channel on which the multicast traffic is to be transported in a channel resource which may include a representation of bandwidth and time interval. In accordance with an aspect of the invention, the common control channel is associated with a traffic channel in a prescribed fixed manner. Further, the traffic channel used for the purpose of multicast can be the same traffic channel used for the normal point-to-point transmission of traffic data.
