Abstract: front page image
(EN) Mobile stations include a data pump functionality for performing digital bit to waveform coding on a received digital data signal. The waveform coded output (analog data signal) is transmitted over the analog air interface using either an analog traffic channel or analog control channel. For transmission over the analog control channel, the data pump functionality multiplexes the wave form coded analog data signal with mobile station generated cellular system control signals. A data pump functionality is also provided at the other end of the air interface transmission to recover the digital data signal from the waveform coded analog data signal transmission. De-multiplexing of the received analog control channel transmission to extract the data signal is also performed, if necessary. For a data communication sent instead to the mobile station, the reverse operations are performed by the included data pump functionalities at either end of the analog air interface. Thus, the mobile station supports the carrying of IS-130/135 modem functionality on either an analog traffic channel or an analog control channel.
