A Real Time Voice Transmission Method for Voice Privacy between CDMA Mobile and PSTN Terminal

초록

영어

To realize the voice privacy between CDMA mobile phone and PSTN terminal, the voice
frames shall be transmitted transparently between the heterogeneous networks. For satisfying
this requirement, we propose the method which transmits voice frames by the CDMA circuit
data channel in real time.
In this paper we analyze the causes of voice delay which occurs during voice transmission
by circuit data channel, propose methods which overcome the voice transmission delay and
prove proposed methods by the experiment.
