Abstract: A method and apparatus for increasing the data rate and providing antenna diversity using multiple transmit antennas is disclosed. A set of bits of a digital signal are used to generate a codeword. Codewords are provided according to a channel code. Delay elements may be provided in antenna output channels, or with suitable code construction delay may be omitted. n signals represent n symbols of a codeword are transmitted with n different transmit antennas. At the receiver MSLE or other decoding is used to decode the noisy received sequence. The parallel transmission and channel coding enables an increase the data rate over previous techniques, and recovery even under fading conditions. The channel coding may be concatenated with error correction codes under appropriate conditions.

Abstract: A method and apparatus for enabling providers of PSTN toll free services to stagger simultaneous transmission of call setup signaling messages into an IP based teleconference bridge, supported by a VoIP network, by suspending a subset of calls and placing them on hold while placing other calls to be connected to the conference bridge are disclosed. The PSTN network can stagger calls by limiting the number of call setup signaling messages to be sent to the VoIP network within a predefined period of time interval and spread all the calls over multiple of such predefined periods. Prerecorded announcements or music can be played while the calls that have been placed on hold are in queue.

Abstract: The present invention is a technique for provisioning and assessment of voice quality in Internet Protocol (IP) voice applications. A predetermined quality of service (QoS) is received from a user in the form of an acceptable packet loss. The technique measures current packet loss and delay in the network and in the terminal, and determines and optimum play-out delay for the use by a play-out adaptation routine. An actual QoS is reported back to the user. To enhance packet delay and loss measurement, a QoS engine component is placed on the terminal side of the packetizer, therefore including packetizer losses in any measurement of the network.

Abstract: A method and apparatus for enabling IP service subscribers to share media contents with other IP service subscribers or Internet users in either a secured or open fashion are disclosed. In one embodiment, the present invention enables the sharing of home movies, pictures, and other media contents, where media could be stored media or media created in real-time. Namely, the present method allows IP service subscribers to effectively create their own TV station, e.g., complete with stored or live content programming and content scheduling. In turn, the method allows a viewing subscriber to select and view a shared media program created by another subscriber.

Abstract: The present invention enables users of packet-switched network services, e.g., VoIP network services, to hear a very gentle whispering tone that quietly conveys the identity of the calling party when they are engaged in conversation and to receive a call-waiting signal. The tone is audible only to the called party but does not mute the ongoing conversation path. This enables subscribed users to hear their ongoing conversation while receiving the whispering tone.

Abstract: The invention describes a method for hardening a security mechanism against physical intrusion and substitution attacks. A user establishes a connection between a network peripheral device and a network via a security mechanism. The security mechanism includes read only memory (ROM) that contains code that initiates operation of the mechanism and performs authentication functions. A persistent memory contains configuration information. A volatile memory stores user and device identification information that remains valid only for a given session and is erased thereafter to prevent a future security breach. A tamper-evident enclosure surrounds the memory elements, which if breached, becomes readily apparent to the user.

Abstract: An IS-OFDM system for point-to-point wireless communications that suppresses narrow-band interference comprises an IS-OFDM transmitter and an IS-OFDM receiver, wherein a transmitted signal comprises a plurality of subcarriers, and further wherein each subcarrier contains more than one and potentially all symbols transmitted in a given frame. The IS-OFDM transmitted signal is at a data rate that is equal to the data rate of the input data stream via the use of P/S converters.

Abstract: A method and system for analyzing deficiencies in a packet-switched network is described. In one example, network measurement data pertaining to components within a packet-switched network are obtained. Reliability estimates of access networks and associated access links coupled to the packet-switch network are conducted. Lastly, an end-to-end direct measure of quality (DMOQ) is calculated from the network measurement data and network estimation data derived from the reliability estimates.

Abstract: The present invention enables an alert message and the display of calling party identity on all on-hook phones associated with an extension sharing the same phone number, when one phone is off-hook and in use. In one exemplary embodiment, this capability enables all other members of a household to receive information regarding an incoming call even when one phone is in use by another member.

Abstract: A method includes receiving multiple alarm messages, each being associated with a failure associated with a service feature available within a telecommunication network. A failure rate for a type of failure having a common set of service feature failure characteristics is determined from the alarm messages received. When the failure rate exceeds a threshold, a maintenance ticket is generated automatically.

Abstract: Method and apparatus for re-routing a call in a packet network during failures is described. In one example, a failure condition is detected for a destination endpoint for the call. At least one alternative endpoint address is identified from an alternative routing plan registered with the packet network in response to the failure condition. For example, various alternative routing plans may be registered with the packet network and stored in a database. Each of the alternative routing plans may include alternative endpoint address data for a plurality of endpoint devices. The database may be queried using the destination endpoint as an index value and the at least one alternative endpoint address may be retrieved. The call is then routed to the at least one alternative endpoint address.

Abstract: An OFDM system embeds sequence information in the transmitted signal that reduces peak average power ratio (PAP) with minimal impact on the overall system efficiency. A marker is embedded onto the transmitted information that is used to identify the combining (inversion) sequence at the receiver. In one embodiment, selected tones in a cluster are rotated when the corresponding phase factor rotates the cluster.

Abstract: The present invention provides a method and system for reducing the peak to average power ratio (PAP) of a signal with low computational complexity. According to one embodiment, the present invention is applied to reduce the PAP of an OFDM signal. According to an alternative embodiment, the present invention, is applied to reduce the PAP of a CDMA signal. Rather than seeking the optimum solution, which involves significant computational complexity, the present invention provides for a number of sub-optimal techniques for reducing the PAP of an OFDM signal but with much lower computational complexity.

Abstract: A method and apparatus for collecting and processing line performance data transmitted over cables, e.g., Y-cables, is disclosed. The present invention applies a method based on specific performance measurements, specific measurement time intervals, and compare results from different measurement time intervals to produce a “signature” that indicates deteriorating performance of a particular Y-cable. Once a “signature” is detected, the method will proactively and automatically generate a trouble ticket to trigger the dispatch maintenance staffs to service the cable, e.g., to perform the replacement of the Y-cable in question, thus completing the predictive maintenance process. A trouble ticket is a record used to report and manage the resolution of network related problems.
