Provided is a system for wireless communications including several base stations supporting a wide area wireless network and several mobile user equipment (UE) devices. Each mobile UE device may be configured to transmit a request to establish a local wireless connection with one or more of the UE devices. The mobile UE device may receive a response containing connectivity information from each of the mobile UE devices and then select one of the mobile UE devices based on the connectivity information received from each of the mobile UE devices. The mobile UE device may then establish a local wireless connection with the selected mobile UE device. The mobile UE device may then communicate with one of the base stations in the wide area wireless network through the selected mobile UE device, utilizing the local wireless connection.

Disclosed are various systems and methods for controlling a voice activity detector. In one example approach, a method is provided in which a voice over Internet protocol (VOIP) session is initiated in a first gateway with a second gateway. A plurality of jitter adaptation packets are transmitted from the first gateway to the second gateway. Also, the voice activity detector is disabled in the first gateway during the transmission of the jitter adaptation packets. The voice activity detector is enabled in the first gateway after the transmission of the jitter adaptation packets.

Delayed onset of voice activity detection for jitter adaptation

An improved data communication technique may be employed with modems through a packet network. The disclosed technique facilitates a virtual end-to-end connection between two modems such that the two modems can effectively behave as if directly connected to each other, unaware of any modifications to the data being transferred or to the protocols configured within the communication connection. Preferably, a data communication system for carrying out the communication technique demodulates data coming from a first modem, transports the demodulated data in packets between two gateways, and then remodulates the data before delivering to a second modem at the other end. In accordance with various aspects of the present invention, various alternatives for calling and quality of service set-up mechanisms, the establishment of a communication session, the transport of data during a communication session, the flow control between all system components involved, and the mechanisms for the termination of communications are also provided.

In accordance with one aspect of the present invention, the detection of voice signals versus modem signals in a data communication system may be conducted, a determination can be made whether existing VoIP algorithm functions or characteristics may be appropriate for modem communications, and then the VoIP algorithms may be modified to improve operating conditions for a modem connection. Additionally, the existing VoIP algorithm functions and network characteristics within the data communication system that may degrade modem performance can be identified prior to the determination of whether the VoIP algorithm functions are appropriate for modem communications. In accordance with another aspect, the detection between voice signals and modem signals can also comprise the determination as to a particular type of modems signal. Further, control of the adaptive jitter buffer to remove or reduce adaptation during detection of modem signals can be provided.

Methods and apparatus for data communications on packet networks

A data communications system and method are provided, for example, in a facsimile machine to establish a data link with a gateway over a local loop. The data link is established employing pulse code modulation with prioritization in the upstream direction. Alternatively, a modulation type may be employed that is equivalent to pulse code modulation that provides similar or higher speed data communication. By using pulse code modulation in the upstream direction, the resulting facsimile transmission in accomplished with much greater speed.

A method and apparatus for sensing audio frequency-pressure modulation of the moisture content of the atmosphere caused by a moisture-laden audio source, such as a live human voice, is disclosed. A first light emitter is provided to generate a first light beam. An audio source that emits moisture, and the environment, modulate the first light beam to generate a first modulated light beam. A first detector is provided to detect and demodulate the first modulated light beam to recover an uncompensated audio signal. A second light emitter is provided to generate a second light beam. The second light beam is modulated by the environment and not by the audio source to produce a second modulated light beam. A second detector is provided to detect and demodulate the second modulated light beam to recover the signal component caused by environmental conditions. A differential amplifier is provided to generate a compensated output signal representing the difference between the uncompensated audio signal and the signal component caused by environmental conditions. The output signal can be transmitted for amplification, distribution, and/or recording.
