  • Patent number: 8670418
    Abstract: Methods and systems in a wireless receiver for enabling the reception of input signals at varied power levels in the presence of co-channel interference utilizing combinations of space-time adaptive processing, interference cancellation multi-user detection, and combined techniques. In multi-user detection, code, timing, and possibly channel information of multiple users are jointly used to better detect each individual user. The novel combination of adaptive signal reconstruction techniques with interference cancellation techniques provides accurate temporal cancellation of interference with minimal interference residuals.

  • Patent number: 8645282
    Abstract: A Secure Virtual Point of Service (SVPOS) that coordinates the authentication, authorization, and identity, settlement, arbitration and non-repudiation for an electronic commercial transaction. For each commercial transaction, both the buyer and merchant authenticate itself to the SVPOS and create two unique transaction encryption keys, one for the buyer and one for the merchant. The merchant uses both encryption keys to encrypt a package that include at least product identification. The merchant and buyer calculate a hash of the package and transmit the calculated hash to the SVPOS for comparison to prevent repudiation. If the calculated hash is identical the buyer receives the merchants encryption key and decrypts the package. Payment is released by the SVPOS if the buyer is satisfied with the package via a Parlay system. If the buyer is not satisfied, said SVPOS performs arbitration between the buyer and merchant to determine if the package is correct.

  • Patent number: 8630224
    Abstract: Disclosed is an improved proactive location based routing protocol for ad-hoc wireless networks. When a source node has a data packet to send to a destination node, the source node calculates an estimated future location of the destination node prior to forwarding a data packet to the destination node. The estimated future location may be based on the last known location, velocity and bearing of the destination node, as well as upon the estimated propagation delay (i.e., the estimated time it will take the data packet to reach the destination node after being transmitted by the source node). The source node routes the data packet by identifying which one of a plurality of its neighbor nodes is closest to the estimated future location of the destination node, and routes the data packet the identified neighbor node as an intermediate node along the route from the source node to the destination node. Further, the frequency of flooding broadcasts is based on the velocity of the network nodes.

  • Patent number: 8625986
    Abstract: A method and system to economically monitor an optical OOK signal that can detect perceptible changes in signal quality and identify the type of optical impairment causing the change. The invention requires a new and novel combination of known techniques to create an eye diagram of the transmitted pulse in a wavelength division multiplexing systems and then removing the noise from the eye diagram. Economy of operation is achieve by using asynchronous sampling techniques for generating the eye diagram. The resulting “cleaner” eye diagram is then analyzed to identify any changes in performance. In the preferred embodiment, the analysis is conducted on histograms generated from eye diagram, the histograms are computed at a number of points across the optical signal pulse period.

  • Patent number: 8620259
    Abstract: A method and apparatus for implementing new services is disclosed whereby a model of the system implementing a new service is created by a function referred to herein as a Service Designer and then different views of the service from the perspective of individual OSS subsystems are published at a Service Hub for use in configuring new services. When a request for service arrives at a subsystem in the network, such as an ordering system, that subsystem will illustratively request a view of the service from the Service Hub. This view is representative of the interfaces and attributes common between the requesting subsystem and other network components, with interfaces to the requesting subsystem. The requesting subsystem then uses this view to transmit values of attributes that are defined to be communicated between the requesting subsystem and other network components.

  • Patent number: 8615071
    Abstract: A generic approach for identifying, authenticating, and correlating a received massage with a particular event and a particular recipient, regardless of the number of events, number of recipients and types of media used for the originally sent message, is achieved by the inclusion of a unique ID embedded in each originally sent message. Upon receipt of an incoming reply message, a parser extracts the unique ID information provided by the recipient from the message for correlation of the incoming message with the associated sent message.

  • Patent number: 8509166
    Abstract: A resource scheduling and power allocation technique is provided for a LTE radio network integrated with femtocells. The technique utilizes a tri-phase approach that includes a stochastic geometric model of an exemplary radio network that generates a channel attenuation matrix for each channel at each PRB. A resource scheduling and power allocation procedure determines a near optimal assignment of mobile user to PRBs based on the channel attenuations, potential data rates, and transmit power subject to maximizing the data rates in accordance with a fairness objective. A discrete-event simulation procedure simulates the end-to-end transmission of the data packets in a packet-switch network in accordance with the assignments to analyze the behavior of the overall network.

  • Patent number: 8448159
    Abstract: A system and method for allowing external execution-time adaptation of application behavior of an application in a telecommunication system without modification to the application code comprises an application having at least one break point and residing on an application server, at least one identifiable decision engine, and a listing of break points that has for each break point at least one identifier of the decision engine, such that at one of the break points, the application accesses the listing of break points, invokes the listed instances of the decision engine corresponding to the break point, and adapts application behavior based on the decision engine. In addition, each entry in the listing of break points can have a sequence number so that if two entries for the same break point have equal sequence numbers, the decision engines identified in these entries can be invoked in parallel.
