Abstract:
A system for conducting wireless communication involving voice and facsimile data comprising:a facsimile device for providing facsimile data; anda radio telephone connected to said facsimile device, said radio telephone havinga speaker/microphone for receiving voice signals;a vocoder connected to said speaker/microphone for receiving the voice signals from said speaker/microphone and for encoding the voice signals for wireless transmission;a protocol stack for receiving the facsimile data from said facsimile device and for encoding the facsimile data for wireless transmission;a radio modulator/demodulator for receiving signals encoded for wireless transmission, for modulating the signals as wireless signals, for transmitting the wireless signals using an antenna over a wireless channel and for receiving and demodulating signals received by the antenna over the wireless channel;a switch interconnecting said vocoder, said protocol stack and said radio modulator/demodulator; anda mobile unit control processor for controlling operation of said vocoder, said protocol stack, said radio modulator/demodulator and said switch;with said mobile unit control processor operating in response to receipt of facsimile data from said facsimile device to control said switch to route facsimile data encoded for wireless transmission from said protocol stack to said radio modulator/demodulator for wireless transmission over the wireless channel and to route responsive signals received by said radio modulator/demodulator over the wireless channel to said protocol stack;with said mobile unit control processor operating in response to receipt of a voice connection request signal during transmission of the facsimile data to control said protocol stack to incorporate an encoded voice connection request signal into the encoded facsimile data being routed to said radio modulator/demodulator for wireless transmission over the wireless channel; andwith said mobile unit control processor operating in response to detection of the completion of transmission of facsimile data in which a voice connection request signal had been encoded to control said switch to route voice data received from said speaker/microphone and encoded for wireless transmission by said vocoder to said radio modulator/demodulator for wireless transmission over the wireless channel before other communication systems can use the wireless channel and to route responsive signals received by said radio modulator/demodulator over the wireless channel to said vocoder for output using said speaker/microphone.
