Abstract: The present invention advanced voice application system takes advantage of information, or attributes, built into a telecommunications network to determine the risk that a call is a fraudulent call in a voice recognition and verification system. To achieve this end, information relating to the telecommunications network are stored in a database as various risk factors. Thus, depending on the type of risk factors associated with a particular call, the risk assigned to that call can be raised or lowered so that the network would not reject a valid caller even though the voice pattern of the caller does not match exactly with the prestored enrolled voice print of the caller. Such risk assessment allows the management of the network to tighten the security of the system without overburdening the caller with questions and also permits calls to be completed for valid subscribers that otherwise would have been rejected.

Abstract: A centralized restoration system utilizes preferred routing tables to identify an optimal restoral path for restoring a network from a failure. The preferred routing tables are constructed prior to the failure of the network. This pre-construction of the preferred routing tables prior to network failure substantially diminishes the computational and temporal requirements needed to restore the network at the time of failure. The centralized restoration system is able to account for changes in network topology and configuration. The centralized restoration system builds the optimal restoral path on a link by link basis and examines the availability of links prior to adding the link to the optimal restoral path. Unavailable links are not added to the restoral path.

Abstract: In the preferred embodiment, the transmission length of the non-full rate frame is shortened frame in order for the mobile terminal 100 to monitor other frequencies with a single receiver. Modulated symbols of non-full rate frame are transmitted with reduced repetition maintaining the sum of repeated symbol energy. Generally, for 1/n (n=2,4,8) length transmission, 1/m (m≧n) rate frame repeated m/n times and transmitted with n/m symbol energy of the full rate frame. The system may use rate limitation to generate a non-full rate frame. A position of the transmitted symbols may be randomized by a mobile specific predetermined random code to minimize interference between terminals different from each other. For intensive frequency scanning and synchronization signal transmission, non-transmitting period can be assigned for successive frames of some interval.

Abstract: An embodiment of the present invention provides a system and method for selecting voice compression and coding based on capabilities of all intermediary networks and links in addition to the capabilities of the end points. The present invention optimizes voice quality by determining a minimum number of new conversions, herein referred to as transcodings, necessary in voice connections, on a system wide basis. According to an embodiment of the present invention, a sender sends a signaling message to a receiver. The signaling message is sent to the receiver prior to sending an actual message. Each entity or device capable of converting voice coding, herein referred to as a “station”, between the sender and the receiver identifies their capabilities to the signaling message. The receiver, which is also a station, also identifies its capabilities to the signaling message.

Abstract: Asymmetric Digital Subscriber Line (ADSL) data service and Plain Old Telephone Service (POTS) are provided over a subscriber loop by an ADSL transceiver and a control processor located in a local communication center, and a subscriber ADSL modem at the subscriber location. The control processor is responsive to a detection of an origination of a POTS call for generating a first control signal that causes the ADSL transceiver to load ADSL data into tone bins which are only in a frequency band above a predetermined frequency band used for a POTS call for data transmissions over the subscriber loop. The control processor is also responsive to a detection of a termination of a POTS call for generating a second control signal that causes the ADSL transceiver to load ADSL data into tone bins which are in both the predetermined frequency band used for a POTS call and the frequency band thereabove for ADSL data transmissions over the subscriber loop.

Abstract: A system for dynamically generating documents utilizes document programs and data at a content providing server to generate those documents. When an intermediate server requests a dynamically generated document from a content providing server, the content providing server transmits the instructions or programs to create the document along with data utilized by the program or instructions in creating the document. The intermediate server then retains or caches the document programs as well as the data. When the intermediate server next requires the document, that document is generated at the intermediate server rather than requiring that it be obtained from the content providing server. The content providing server retains a register of the intermediate servers which have received document programs or data. If there are changes to the document programs or data, such changes are broadcast to the intermediate servers which had cached that information.

Abstract: In accordance with the present invention a method and apparatus are disclosed in which each data stream of a plurality of data streams is assigned to a queue and each queue is allocated a predetermined maximum numbers of buffers. Once the queue has exhausted its supply of buffers, the data from the corresponding data stream is discarded until buffers are refreshed thereby allowing the remaining data streams to operate in a normal fashion. Accordingly, excessive buffer usage by an individual data stream is prevented, as well as excessive demand of other related system resources such as CPU time. The data stream which has had its data discarded will begin having its incoming data processed upon the next refresh operation providing the queue associated with that data stream has had additional buffers allocated. The discarded data is lost and is not recovered. The refresh operation is performed in a manner that provides prioritization of the queues and a high degree of fairness within each priority level.

Abstract: A video/audio alarm processing method and apparatus for a base station manager in a mobile radio communication system capable of classifying trouble state data of base station controllers and base stations by grades and informing to a user the trouble state as video and audio alarms in accordance with the classified grade of the trouble state data. According to the method, the data of a predetermined number of bits which is received from the base station controllers and base stations is converted and stored, and whether the trouble state data exists or not in the stored data is judged. If the trouble state data exists, it is classified by grades, and the video and audio alarms are produced in accordance with the classified grade of the trouble state data.

Abstract: A method and apparatus for performing logical multicasting within a network switch are disclosed so as to permit a downstream network device to perform cell forwarding in a manner which resembles spatial multicasting. A logical multicast cell has a connection identifier associated with the cell within the switch. The connection identifier is employed to initiate a series of lookup operations to generate unique VPI/VCI addresses which are transmitted out of an output port of the switch as copies or leaves of the multicast cell. Successive look-ups of outgoing VPI/VCI addresses for a logical multicast cell are performed using a chain bit to indicate when all leaves of the cell have been transmitted. Leaves of a logical multicast cell are transmitted to the downstream network device from one output cell buffer of a plurality of output cell buffers associated with the output port of the switch so as to minimize the likelihood of blocking and so as to minimize cell delay variation.
