摘要

容纳具有各种传输速率的综合业务的一种方法是在CDMA移动通信系统中使用多码传输。然而，同时传输多个信号会增加呼叫阻塞并降低通信质量。我们之前提出了一种动态小区配置(DCC)方案来减少CDMA系统中不均匀通信量的不利影响。在本研究中，我们评估了语音/数据集成流量使用多码传输的环境下的DCC性能。结果表明，DCC的使用降低了呼叫阻塞概率，提高了数据用户和语音用户的通信质量。

CDMA dynamic cell configuration scheme for voice/data integrated traffic

One way of accommodating integrated traffic having various transmission rates is to use a multi-code transmission in CDMA mobile communications systems. The simultaneous transmission of multiple signals, however, increases call blocking and degrades communications quality. We previously proposed a dynamic cell configuration (DCC) scheme for reducing the adverse effects of non-uniform traffic in CDMA systems. In the present study, we evaluated the DCC performance for environments in which voice/data integrated traffic is flowing using multi-code transmission. It is shown that the use of DCC reduces call blocking probability and improves communications quality for data-users as well as voice-users.
