| 摘 要： | 基于话音和数据业务各自不同的服务质量（QoS)要求，提出了一种综合话音／数据业务的码分多址（CDMA）系统接入控制方案，设定话音业务优先级高于数据业务，且限制话音用户最大可用码道数量，以保证数据业务的吞吐量，仿真结果表明，该方案充分利用了通话间隙，从而避免浪费有限的频带资源，提高了数据业务的传输效率。

| Abstract: | Based on the different quality of service(QoS)for voice and data traffic, an access control protocol for the integrated voice/data packet code division multiple access(CDMA)was proposed. By giving higher voice calls priority than data packets, restricting the maximum number of codes available to voice traffic, the throughput of the data traffic was assured. The simulation results show that this protocol makes use of the silent interval of voice efficiently and improves the throughput of data traffic. |
