Methods and apparatus for enhancing wireless data network telephony, including quality of service monitoring and control

摘要

A system for wireless communication comprises an architecture of routers connected to a network and having connected transceivers for wireless transmission and reception of data, and a plurality of hand-held commuoicators adapted for users to communicate with the network through the routers. The system is adapted to provide wireless Data Network Telephony (DNT), and the hand-held communicators execute Quality of Service (QoS) code adapted to prioritize DNT packet code over all non-DNT traffic, thereby preserving the real-time nature of the DNT code.

主权项

1. A hand-held communication device, comprising:
microphone aod speaker apparatus including converters for reoderiog audio data as audible speech, and for rendering audible speech as audio data; a communication interface comprising circuitry for receiving and sending the audio data on a cell-phooe network as Data Network Telephony (DNT) packets; and circuitry including Digital Signal Processor (DSP) recognizing human speech and processing audio data for DNT calls, the circuitry prioritizing DNT data over any other data when transmitting on the cell-phone network, allowing substantially only human speech to be prepared as DNT packets for transmission.
