摘要

提出了一种码分多址(CDMA)蜂窝系统架构的设计方案。该基站架构基于一个通用平台，可以在同一基站中支持CDMA和其他蜂窝标准，如AMPS和TDMA。对移动交换中心(MSC)体系结构进行了改进，以支持各种CDMA系统特性，如软切换和可变比特率语音编码。特别是，MSC的数字蜂窝交换机(DCS)为基站提供帧中继分组交换接口。结果表明，这种分组交换接口比传统的DS0/DS1电路交换接口能够支持更多的语音通道，是实现软切换能力的重要组成部分。

Architectural design of a code division multiple access cellular system

A design of the code-division multiple access (CDMA) cellular system architecture is presented. The base station architecture is based on a universal platform that can support CDMA and other cellular standards such as AMPS and TDMA in the same base station. The mobile switching center (MSC) architecture is enhanced to support the various CDMA system features such as soft handoff and variable bit rate vocoding. In particular, the digital cellular switch (DCS) at the MSC provides a frame relay packet switching interface to the base station. It is shown that such a packet switching interface can support more voice channels that the conventional DS0/DS1 circuit switching interface and is an essential element in achieving the soft handoff capability.<>
