Abstract: A method of data flow control between a mobile and base station of a wireless communication system where the mobile is transferring wirelessly part or all of the data received from the base station to a local device in accordance with a standard such as Bluetooth or Wi-Fi. The rate at which the mobile is receiving data from the base station is typically much higher than the rate at which the mobile is transferring the data to the local device. The mobile sends a STOP data flow control command to the base station causing the base station to either stop transmitting data or transmit data at a lower data rate thus prevention mobile buffer overflow and loss of data from occurring. When conditions are favorable for reception of data, the mobile sends START data flow control commands to the base station allowing the base station to resume transmitting data at a higher data rate. The higher data rate may be equal to the original established data rate.

Abstract: In a UMTS, the AICH is arranged to send, in addition to a signal acknowledging that a preamble from a mobile is at an acceptable strength, an additional signal indicating that the mobile is not currently permitted to send its message; this may apply when the BTS does not have hardware resources available. If the BTS can predict when the hardware will become available, the additional signal can include a time out (T) after which the mobile system can send its message signal.

Abstract: In the method and apparatus for transmitting data packets, a source device places identifiers in data packets being transmitted. The identifiers identify data packets that the source device considers properly received by a destination device or identify data packets that have had their transmission aborted by the source device. When the destination device receives data packets including these identifiers and the identifiers identify data packets that the destination device has yet to receive, the destination device will proceed as if the identified data packets have been re-sequenced.

Abstract: A method is provided of detecting one of a set of preamble sequences in a spread signal. The method includes: (a) correlating the received spread signal with sequences of a first orthogonal Gold code (OGC) set in accordance with a first fast transform to provide a preamble signal; (b) correlating the preamble signal with the set of preamble sequences in accordance with a second fast transform to generate a set of index values; (c) forming a decision statistic based on the set of index values: and (d) selecting, as the detected one of the set of preamble sequences, a preamble sequence corresponding to the decision statistic.

Abstract: A precise array of collimated light beams may be obtained by employing a chuck to tightly hold as an array a group of precision collimators attached to individual optical fibers. Advantageously, such arrays of collimators may be manufactured to very high tolerances so as to be useful in positioning collimated light beams for all-optical switching.

Abstract: QoS scheduling is used for handling multiple data flows in packet switched cellular systems, especially in a packet switched mobile telecommunication system, wherein the scheduling mechanism of a specific cell is coupled with the scheduling mechanism of at least one second cell, in particular by transferring data between the specific cell and at least one second cell comprising a status information concerning data flow within the specific cell.

Abstract: A scheduler apparatus provides bandwidth guarantees to individual data packet flows as well as to aggregations of those flows (referred to as “bundles”) in a completely transparent manner, i.e., without using any additional scheduling structure. For each bundle, the scheduler determines the ratio between the bandwidth nominally allocated to the bundle and the sum of the individual bandwidth allocations of the flows that are currently backlogged in the bundle. The scheduler uses that ratio to modulate the timestamp increments that regulate the distribution of bandwidth to the individual flows. In this manner, the greater the ratio for that bundle, the more the bandwidth that each backlogged flow in the bundle receives.

Abstract: A secure protocol is provided which uses a Diffie-Hellman type shared secret, but modified such that the two parties may authenticate each other using a shared password. In accordance with the invention, a party generates the Diffie-Hellman value gx and combines it with a function of at least the password using a group operation, wherein any portion of a result associated with the function that is outside the group is randomized. The resulting value is transmitted to the other party. The group operation is defined for the particular group being used. Every group has a group operation and a corresponding inverse group operation. Upon receipt of the value, the other party performs the inverse group operation on the received value and the function of at least the password, and removes the randomization of any portion of the result associated with the function that is outside the group, to extract gx such that the other party may then generate the shared secret gxy using its knowledge of y.

Abstract: The specification describes an optical pulse generator in a return-to-zero format in which a phase-modulated (PM) optical signal is converted to intensity-modulated (IM) optical pulses using chromatic dispersion. Compared with Mach-Zehnder-modulator-based pulse generators, this scheme is potentially more efficient (lower insertion loss). The pulse generator of the invention is suitable for very high data rates, e.g. 40 Gb/s. The structure of the pulse generator is a phase-modulated pulse source combined with a dispersive element having the required dispersion.

Abstract: A method and apparatus for controlling a bias voltage of a Mach-Zehnder modulator (MZM) use a digital pilot signal and a digital correlation technique to produce a feedback signal for adjusting the bias voltage to the quadrature bias point. Embodiments of the invention include apparatuses performing a non-return-to-zero (NRZ), return-to-zero (RZ), or carrier suppressed RZ (CSRZ) high-speed optical modulation.

Abstract: The present invention provides a burst mode power line data network system having at least one burst mode power line transmitter (BMPLT) and at least one burst mode power line receiver (BMPLR) for enabling signaling, telephony and data communications via power lines without using carrier frequencies. The BMPLT transmits line encoded bursts of information via a power line to the BMPLR which receives the line encoded bursts of information and has a maximum inter-packet idle time of only one bit between bursts. The invention permits the use of AC coupling in a receiver and results in outputting data with constant pulse widths irrespective of optical signal power levels, etc. In one embodiment, a receiver has a wide dynamic range, is highly stable, may be used over all frequencies of interest without developing high speed electronics or optical components, and has no sensitivity penalty as compared to existing burst mode/packet mode receivers.

Abstract: A network-based service where different sets of customized information are delivered to a user at different times to different destinations (i.e., different user devices) selected by the user. More particularly, a user accesses a network-based server, generally owned by a network service provider and defines a user profile which specifies the information or other content to be made available. The user may request that the information be delivered later automatically or be made available on demand. The user has flexibility in requesting a particular format to receive the information on demand. In case of the later delivery, the user requests specified times in a form of a schedule and specified destinations (i.e., user devices) for the delivery of the information. The user also has flexibility in selecting the format for the delivery of information. Sometimes, the format is dictated by the selection of a user device, e.g.

Abstract: One or more processor operations are emulated in a programmable logic device (PLD) (205) that selectively mimics processor behavior by a program that downloads (505) one or more processor operations into the PLD (205). Each operation may be selected (501) and repeated (513) continuously without interruption from any other processor operation unless such interruption is desired to take place. In addition, the PLD (205) has an adjustable or variable clock speed that provides for the ability to select (507) and change (511) the clock speed under which the test circuit is exercised.

Abstract: In general terms, one embodiment of the method is for automatically notifying a subscriber that the subscriber has talked on a mobile terminal for a subscriber-defined amount of time. The method may have the steps of: defining an interval for at least one category of usage of a mobile terminal that is operatively connected to a telecommunication network; storing, at the telecommunication network, the defined interval for the at least one category of usage of the mobile terminal; monitoring, by the telecommunication network, a time that a call has been active on the mobile terminal; comparing the time that the call has been active to the stored at least one interval; and sending a predetermined notification signal from the telecommunication system to the mobile terminal when the time that the call has been active exceeds the stored interval. The system implements the method.

Abstract: An analog decoder includes a controller and an analog decoder core. The analog decoder core has an input of an input length that is less than a code length of the code data. If only a single analog decoder core is implemented, then the controller applies a portion of the code data to the analog decoder core prior to each of a plurality of read operations in which decoded data is read from the analog decoder core. Alternatively, if a plurality of analog decoder cores is implemented, then the controller may apply a portion of code data onto each of the analog decoder cores prior to a single read operation associated with each of the analog decoder cores.

Abstract: An optical fiber cable is tested to determine the zero dispersion frequencies of the sections of which it is made by directing light along it, the light comprising two optical frequency components having optical frequencies that differ by a predetermined amount ??. The frequencies of the components are swept across the operating frequency range of the cable, keeping ?? constant. At the other end of the cable, the spectrum of the light is analyzed to determine the relative powers of first order 4 WM components (satellite lines) and the frequencies at which they have principal maximum values.

Abstract: A communications system includes a base station and a plurality of remote stations wirelessly communicating with the base station and transmitting a requested service rate to the base station. The base station allocates a next transmission of data to the remote stations based on a scheduling operation. The scheduling operation includes determining an average service rate for each remote station and determining a priority value for each remote station based on the requested service rate and average service rate. In allocating the next transmission of data, at least one of the average service rate and the priority value is modified to thereby control data throughput of the communications system.

Abstract: An apparatus provides an optical wavelength division multiplexed signal having 2M optical channels such that each of M information-bearing signals are differentially encoded onto 2 of the 2M optical channels. In particular, the apparatus comprises M inverters, 2M electrical-to-optical converters and a multiplexer. Each electrical-to-optical converter provides an optical signal at a different one of 2M wavelengths. The apparatus receives the M information-bearing signals and (a) creates M optical signals, each at a different wavelength, by converting each of the M information bearing signals into the optical domain via M of the 2M electrical-to-optical converters, and (b) creates M inverted optical signals, each at a different wavelength, by first inverting each of the M information bearing signals (via the M inverters) before conversion into the optical domain via the remaining M electrical-to-optical converters.
