Abstract: In a cellular telephone terminal having increased storage capability, ease of entry and access for data stored therein is provided through utilization of a computer equipped with a modem, a wired telephone network and the cellular telephone network. A user utilizes the ease of data entry implicit to modern computers through dedicated or existing personal information organizers to input data into a database, such as a personal dialing directory, at the computer. For the entering of data at the cellular telephone terminal, first the terminal, also equipped with a modem, is configured in a data download mode where data can be received from the computer and entered into on-board storage. The computer then places a modem telephone call to the terminal, either directly or through a network translator, and transfers the data into the terminal. The data is then accessible through standard data recall techniques using a display and interface keys on the telephone terminal.

Abstract: In the method, a source base station sends first information to a target base station. The first information indicates a sequence number of a first data unit in a sequence of data units undelivered to the mobile station by the source base station. The source base station also sends the target base station second information. The second information indicates data units, after the first undelivered data unit in the sequence, that have been delivered to the mobile station by the source base station. The second information may further indicate portions of the first undelivered data unit that have been delivered to the mobile station by the source base station.

Abstract: The present invention provides a method and an apparatus for forming an antenna beam from an array antenna having a rear facing side, an aperture, and including a first and a second radiating element. The method comprises injecting a synchronization signal wirelessly from a common source at the rear facing side of the array antenna to provide an initial calibration of the array antenna that synchronizes phase of an output signal from the first and second radiating elements to the common source. The method further comprises compensating a change in phase of the synchronization signal at the first radiating element based on a spatial displacement to synchronize phase of a first portion of the output signal from the first radiating element to the phase of the synchronization signal at the second radiating element in response to the spatial displacement of the first radiating element after the initial calibration of the antenna array.

Abstract: The channel quality indicator (CQI) transmitted by a mobile terminal to a base station is indicative of the Ec/Nt pilot SNR of the pilot signal transmitted by the base station and measured by the mobile terminal. The base station uses the CQI for purposes such as determining a downlink rate, a modulation scheme, and downlink power. Knowledge by the base station of whether the received and detected CQI is likely to be “good” or “bad” would be useful in determining how and whether the value of the received and detected CQI should be used. In a first embodiment, at the base station, a reliability of the received CQI that is detected from received soft symbol metrics is determined in conjunction with the detected CQI value for the received CQI word as a whole.

Abstract: A network node computes a fair share data rate for the sharing of a shared communication channel in a local area network. The network node determines the required information for computing the fair share by snooping the network, by receiving the required information from other network nodes, or a combination of the two techniques. Alternatively, instead of computing the fair share data rate, the network node may receive the fair share data rate which was computed by another network node. The fair share data rate is enforced by the network node in a network protocol stack layer above the media access control layer. In one embodiment, the network protocol stack layer above the media access control layer is the link layer.

Abstract: The present invention provides a method and an apparatus for responding to changes in measurement of a system load in a spread spectrum communication system. Using a load control algorithm, for example, the spread spectrum communication system may handle sudden changes or variations, such as spikes or steps in system load measurements for an uplink and/or a downlink between a mobile unit and an access network. The load control algorithm determines whether a sudden variation of a measured system load is generated by a source not under a power control or is caused by a variation of a spread spectrum communication system load. A load control measure may be selectively applied to adjust one or more parameters associated with the system load.

Abstract: A communication method is provided, in which a data vector u which contains respective signal data destined for each of a plurality of users is transmitted from multiple antennas or other transmitting elements. Prior to transmission, a perturbation vector ?l is added to the data vector u, in which ? is a positive real number and each component of the vector l is a complex number whose real and imaginary parts are both integers. This perturbation is beneficial for improving the total rate of data transmission.

Abstract: Spam filtering methods and systems are provided for filtering spam SMS SMPP messages from an ESME to an SMSC associated with a wireless network, in which an anti-spam application receives SMPP SMS messages from the ESME and performs spam filtering prior to providing SMPP messages to the wireless network, with good messages being forwarded to the SMSC of the network and spam messages being discarded or persisted.

Abstract: A method for target acquisition and tracking of a moving station or target (e.g., an unmanned aerial vehicle) for carrying out free space optical communications uses an “elapsed time”-based approach to determine the position of the moving station at any future time, based on the time difference since the moving station's last known position. For example, the vehicle may be for purposes of reconnaissance, where the optical link provides a secure and high-bandwidth communications pathway between the moving station and a ground station. A mathematical model of the moving station's expected periodic flight path is combined with position and time elements to accurately predict the future position of the moving station for target re-acquisition. The model is a cubic spline interpolation of known flight path waypoints. The system may also employ multiple waypoints in initial acquisition, by alternating acquisition attempts over several waypoints instead of “staring” at a single waypoint.

Abstract: Methods and systems are presented for filtering spam MAP SMS messages in an SS7 network, including mobile originated and mobile terminated MAP SMS messaging to mitigate spam-related traffic in the SS7 network. The system includes an anti-spam application (42) running on one or more network servers (40) that receives the MAP messages before routing to any SMSC or MSC, and classify these as spam or good. The good MAP SMS messages are then provided to the corresponding destinations by appropriate SMSC or MSC in the SS7 network, while the spam MAP SMS messages are not delivered to the SMSC.

Abstract: A method and apparatus for forming an electrically and/or thermally conducting interconnection is disclosed wherein a first surface and a second surface are contacted with each other via a plurality of nanostructures disposed on at least one of the surfaces. In one embodiment, a first plurality of areas of nanostructures is disposed on a component in an electronics package such as, illustratively, a microprocessor. The first plurality of areas is then brought into contact with a corresponding second plurality of areas of nanostructures on a substrate, thus creating a strong friction bond. In another illustrative embodiment, a plurality of nanostructures is disposed on a component, such as a microprocessor, which is then brought into contact with a substrate. Intermolecular forces result in an attraction between the molecules of the nanostructures and the molecules of the substrate, thus creating a bond between the nanostructures and the substrate.

Abstract: An IP sub-network includes a gateway and a plurality of sub-network processors in communication with the gateway. An IP address is associated with each sub-network processor, the IP address having a sub-network address portion corresponding to the sub-network and a host address portion corresponding to the sub-network processor. Each sub-network processor generates a transaction identifier for each signaling message that is communicated by the gateway to the signaling network. The transaction identifier is based on the IP address and can be generated by separating the sub-network address portion of the IP address and concatenating the host address portion with a numerical value, which corresponds to a predetermined, non-random ordering scheme. A signaling message can be routed to a sub-network processor by concatenating the sub-network address portion with the host address portion used as part of the transaction identifier.

Abstract: An optical device extracts an information bearing sideband such as an FSK or SCM signal (label) from a composite signal that includes the sideband and an orthogonally modulated signal such as an intensity modulated signal (payload) by splicing the composite signal into a polarization maintaining fiber at a desired angle so that the composite signal is separated into two orthogonal polarizations that experience differential group delay in the fiber. The polarized output signals from the fiber are then coupled to a polarization beam splitter at an equivalent or complementary angle to the desired angle so that one sideband of the composite signal appears at a first output of the beam splitter while another sideband appears at a second output of the beam splitter. The sidebands can then be converted to an electrical data signal by using an appropriate receiver, such as a balanced receiver for FSK signals.

Abstract: A method and apparatus for enabling a party using a telephony device who is in communication with a mobile device of a wireless network user to leave a voice mail for the mobile device user in the event that the user's mobile device is dropped during a call between said party and said mobile device user.
