Illustratively, the mobile device users can control target communications through the utilization of discretion requests/permissions processed by the third party information arbiter. Furthermore, the mobile device users may further interact with the trusted third party information arbiter to provide/release additional personal information. For example, a mobile device user may be provided an increasingly rich rewards or payments that may be provisioned by discount, coupons or offers associated with existing or new product advertisements or promotional information messages.

Abstract: Systems, methods and interfaces are disclosed for managing communications associated with a mobile communication device. Mobile communication devices process environmental inputs and transmit mobile communication device context information to a communication management system. The context information may, for example, reflect the motion and/or geographic location of the mobile device, and may reflect the risk associated with using the device to handle a call or other communications session. The communication management system uses the context information, optionally in combination with communication device profiles, to determine how to manage incoming and/or ongoing calls or other communication sessions. Mobile device users may also be inhibited from initiating communication sessions.

Abstract: The invention is related to methods and apparatus for controlling and adapting a digital predistortion linearizer for amplification of bandlimited signals using non-linear amplifiers. The control method advantageously permits the predistortion function applied by a predistortion entity to provide a relatively constant gain. This attribute is advantageous for operation within cellular radio systems, which often employ digital power control systems. However, the disclosed techniques can also be applicable to virtually any type of digital predistortion for which an input signal or reference signal to be amplified is predistorted in a manner that is complementary to the distortion induced by a non-linear amplifier. Embodiments of the invention advantageously enhance the practicality of using digital linearization and predistortion amplification techniques.

Abstract: A communication environment includes of one or more subscriber terminals capable of initiating emergency voice calls over a telephony network. The subscriber terminal further send messages over either a data network or a telephony signaling network to a communication management system. The communication management system receives messages from a subscriber terminal, either via a data network or a telephony signaling network. It also consists of one or more telephony switching nodes capable of querying the emergency context node for a called party emergency context. It also consists of one or more servers that provide advanced call control services.

Abstract: The present invention is related to methods and apparatus that compensate for quadrature impairments of an analog quadrature modulator and/or demodulator over a relatively wide signal bandwidth. One embodiment pre-distorts baseband signals in a quadrature modulator compensation signal processor (QMCSP) to negate the quadrature impairment of an analog quadrature modulator and corrects a received baseband signal in a quadrature demodulator compensation signal processor (QDCSP) to cancel the quadrature impairment of an analog quadrature demodulator. The QMCSP and the QDCSP contain adaptive digital filter correction structures that pre-compensate and post-compensate, respectively, for the quadrature impairments introduced by the analog quadrature modulator and the analog quadrature demodulator over a relatively wide bandwidth.

Abstract: The present invention is related to methods and apparatus that advantageously permit the more efficient use of an input range of an analog-to-digital converter used by an adaptive predistortion linearized RF transmitter. A main signal component of a down-converted output of an RF transmitter is removed prior to the analog-to-digital conversion of the down-converted output, thereby allowing more of the input range of the analog-to-digital converter to capture an error signal component of the down-converted output. Embodiments of the present invention can thus adaptively tune the predistortion stage to a higher degree of linearity or can use lower cost analog-to-digital converters with fewer quantization steps for the same performance.

Abstract: The present invention is related to methods and apparatus that can advantageously reduce a peak to average signal level exhibited by single or by multicarrier multibearer waveforms. Embodiments of the invention further advantageously can manipulate the statistics of the waveform without expanding the spectral bandwidth of the allocated channels. Embodiments of the invention can be applied to either multiple carrier or single carrier systems to constrain an output signal within predetermined peak to average bounds. Advantageously, the techniques can be used to enhance the utilization of existing multicarrier RF transmitters, including those found in third generation cellular base stations. However, the peak to average power level managing techniques disclosed herein can apply to any band-limited communication system and any type of modulation. The techniques can apply to multiple signals and can apply to a wide variety of modulation schemes or combinations therof.

Abstract: Systems and methods for analyzing the jitter content of an oversampled digital communication signal are disclosed. Advantageously, the communication signal can correspond to an arbitrary data sequence, rather than only to a repeating test sequence. For example, the systems and methods can be embodied in test equipment and in simulation equipment as design tools and/or validation tools. The systems and methods disclosed advantageously facilitate the decomposition and quantification of the main jitter components (random and deterministic), as well as its various subcomponents (periodic jitter, data-dependent jitter, inter-symbol interference, device-state-dependent jitter, other bounded uncorrelated jitter, and data-dependent-random jitter).
