摘要

Iub接口是第三代移动通信系统（3G）无线接入网中最重要的网络接口之一。文章针对Iub口的传输及现有Iub接口数据采集卡的不足

设计了一种模块化的信道化数据采集卡;提出了一种基于空分交换和时分交换的STM-1/E1复用解复用方法

一种基于扫描单元和扫描索引的自动获取反向复用的异步传输模式（IMA）组捆绑的算法。测试应用表明

该数据采集卡具有较好的灵活性和兼容性。

Abstract

Iub interface is one of the most important network interfaces in 3G radio access networks.In view of the transmission of the Iub interface and the insufficiency of the existing Iub interface data acquisition card

this paper designs a modular channelized data acquisition card

and presents a multiplexin/demultiplexing method for STM-1/E1’ on the basis of space/time division switching and a scanning unit/index-based automatic IMA-acquisition group binding algorithm.Tests and application results show that this card has higher flexibility and compatibility.
