System and method for voice and data over digital wireless cellular system
First Claim
1. A method of combining voice and data for transmission during a single digital wireless telephone call, comprising the steps of:
- establishing a circuit-switched data call connection from a mobile phone to a destination;
routing the call through a pair of modems connected in-line with the call connection path;
multiplexing non-voice digital data with vocoded voice digital data to form a multiplexed digital data stream; and
sending the multiplexed digital data stream from the mobile phone to the destination through the pair of modems.

Abstract
A method of combining voice and data for transmission in a single digital wireless telephone call comprises the steps of establishing a circuit-switched data call connection from a mobile phone to a destination, routing the call through a pair of modems connected in-line with the call connection path, multiplexing non-voice digital data with vocoded voice digital data to form a multiplexed digital data stream, and sending the multiplexed digital data stream from the mobile phone to the destination through the pair of modems.
A telephone for combining voice and data into a digitized data stream for delivery to a destination using a single digital wireless telephone call comprises a vocoder, a microphone, a speaker, a multiplexer having an encoded voice input and a data input, and a demultiplexer having a converted data input and a voice data output. The multiplexer is operatively connected to receive encoded voice output from the vocoder and the data. The demultiplexer is operatively connected to provide received voice data from a decoder in the vocoder and non-voice data.
A system for managing a combined data stream comprises a telephone for combining voice and data into the combined data stream which is transmitted from the telephone to the destination.

7. A telephone for combining voice and data into a transmitted digitized data stream to be transmitted by way of a single digital wireless telephone call and for receiving a received digitized data stream including received voice data and received non-voice data, the telephone having a voice input, a sound output, a data input, a non-voice data output, and an antenna, the telephone comprising:
-
a vocoder having an encoder including a digitized voice input and an encoded voice data output, and a decoder including a received voice data input and decoded voice data output;
a microphone operatively connected to an analog-to-digital converter which provides a digitized voice data stream to the digitized voice input in response to the voice input;
a speaker operatively connected to a digital-to-analog converter which receives a digital data stream from the vocoder decoded voice output to provide the sound output;
a multiplexor having a multiplexed data output, an encoded voice input, and a data input, the multiplexor operatively connected to receive the encoded voice output at the encoded voice input and the data at the data input so as to provide a transmitted digitized data stream; and
a demultiplexor having a converted data input, a voice data output, and a non-voice data output, the converted data input operatively connected to receive the received digitized data stream, the voice data output operatively connected to provide received voice data to the decoder received voice data input, and the non-voice data output operating to provide the received non-voice data to the non-voice data output. - View Dependent Claims (8)
