  • Patent number: 7369494
    Abstract: The invention operates to determine a measure of one or more input data parameters, such as input data rate and input data buffer fill at the beginning of a data burst. The invention then proceeds to the selection of an operating data rate for the data burst as a function of the input data parameter measures. In a further step, the invention proceeds to a selection of a duration for the data burst as a function of the selected operating data rate and an end-of-burst data residue parameter.

  • Patent number: 7370325
    Abstract: An object-focused workflow system for processing a received object in accordance with a declarative workflow specification. The specification includes modules and attributes, where module execution results in the evaluation of attributes, and may include the initiation of a side-effect action performed by an external component. Whether modules are to be executed for a particular received object is determined by associated enabling conditions. Attributes may be evaluated in accordance with computation rules and a combining policy, where the computation rules specify how values are to be contributed to an attribute, and the combining policy indicates how those contributed values are combined in order to assign a value to the attribute. Tasks in the workflow system may be executed eagerly in order to improve the performance of the workflow system.

  • Patent number: 7366548
    Abstract: The present invention provides a method for alerting a mobile unit of a missed call. A mobile unit receives a call request. If the mobile unit does not answer the call request and the mobile unit is stationary, the mobile unit waits for the mobile unit to move. Upon movement, the mobile unit notifies, via an audible tone, vibration, or a visual indicator, that the mobile unit had a call while it was stationary.

  • Patent number: 7366659
    Abstract: Time-scaled, sound signals (i.e. sounds output at differing speeds) are generated by mixing weighted time-and frequency-domain processed signals, the former signal generally representing speech-based signals while the latter representing music-based signals. The weights applied to each type of signal may be determined by a scaling factor, which in turn is related to the desired speed at which a listener desires to hear a sound signal. In one example of the invention, only stationary signal portions of an input sound signal are used to generate time-scaled processed signals. An adaptive frame-size may also be used to pre-process the separate signals prior to being weighted, which at least decreases the amount of unwanted reverberative sound qualities in a resulting sound signal. Together, techniques envisioned by the present invention produce improved, speed adjusted sound signals.

  • Patent number: 7366178
    Abstract: A method and apparatus for scheduling the transmission of data packets over a multihop wireless backhaul network in which delay guarantees through the network may be advantageously ensured. Illustratively, a novel packet scheduling scheme is provided which is advantageously based on an existing scheduling policy for wireline networks and for which a delay guarantee (based on the delay characteristics of the existing scheduling policy) can be advantageously ensured. In one embodiment, an even-odd link activation framework is defined for a given multihop wireless backhaul network, and an associated scheduling policy based on an arbitrary existing scheduling policy for wireline networks is derived and adopted. In such a case, the derived scheduling policy, when applied to the given multihop wireless backhaul network, advantageously ensures a worst-case delay guarantee of approximately twice that of the existing scheduling policy for wireline networks.

  • Patent number: 7366174
    Abstract: Rules for classifying traffic in a communications network are set by collecting traffic data related to traffic that is input into a network node, processing the traffic data that is collected, and setting classification rules in response to the processed traffic data, wherein the set classification rules are used to classify subsequent input traffic. In an embodiment, subsequent traffic is classified according to the set classification rules. In another embodiment, traffic conditioning rules are also set in response to the processed traffic data and subsequent input traffic is conditioned according to the set traffic conditioning rules.

  • Patent number: 7366526
    Abstract: This technique is applied in the circumstances where an intersystem page message, e.g. an IS-41 ISPAGE2 message, is received in a first border switching module. The intersystem page message may originate from a second border switching module. In this case, the network determines whether the second border switching module is manufactured by a different network provider than the first border switching module. If so, a routine to address inconsistencies in the location area parameter is implemented so that an efficient paging strategy can be invoked.

  • Patent number: 7366514
    Abstract: By obtaining the address of a circuit switching controller in a network with which a mobile station is registered, a packet call controller instructs the circuit switching controller to send notification of when a handoff request is received for a mobile station by the circuit switching controller. The handoff request is for transferring a packet switched call to the circuit switching controller as a circuit switched call. The notification request includes an identifier, which the circuit switching controller uses in notifying the packet call controller of the handoff request. In response to the notification, the packet call controller re-establishes call control and bearer paths between the call endpoints.

  • Patent number: 7366196
    Abstract: An out-of-band ranging technique is automatically initiated at a customer premises equipment unit when the equipment is installed, when power is restored after a power failure or interruption, upon verification of the equipment, upon reconnection after a disconnection of the equipment or the like. To this end, an out-of-band tone is employed that is automatically transmitted when the customer premises equipment that transmits the TDMA signal is powered ON, or transmitted in response to a specific command generated locally or remotely. Specifically, when ranging is being effected the customer premises equipment generates and transmits the out-of-band ranging tone until a message is received from a remote terminal indicating that the transmission of the ranging tone be terminated. The loop delay being determined is the delay interval between transmission of the termination message and detection that transmission of the ranging tone has terminated.

  • Patent number: 7366518
    Abstract: Disclosed is a method for utilizing SCH resources more efficiently for supplemental channels (SCH) by minimizing gaps between data bursts due to overhead delays. Such gaps are minimized using a supplemental channel sharing algorithm to prospectively assign SCH resources supporting existing SCHs and to schedule future issuance of DNRs such that currently unavailable SCH resources may be prospectively assigned based on states of the SCH resources, wherein an existing SCH is a SCH over which a data burst is currently being transmitted.

  • Patent number: 7366911
    Abstract: Methods and apparatus are disclosed for generation of secure and efficient digital signatures in an information processing system. The system includes one or more user devices, a signing aid or other intermediary device, and a verifier. A given user device has associated therewith key pairs (s, p) and (s?, p?) corresponding to respective first and second digital signature protocols. As part of a setup process, an agreement relating to the public keys p and p? is signed by both the user device and the intermediary device, and the resulting twice-signed agreement is stored by both the user device and the intermediary device. A first digital signature s1 is then generated on a message m or a hash h(m) thereof in the user device using the secret key s? and is sent to the verifier. The verifier in turn sends s1 to the intermediary, and the intermediary checks that s1 is a valid digital signature for the user device.
