ABSTRACT
<p>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.</p> <p>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.</p>
