Iub口IMA组捆绑算法分析与实现

Analysis and implementation of IMA group binging algorithm based on Iub port

提出了一种基于ST-M1 E1时隙交叉的IMA组捆绑猜测算法,其核心思想是:根据对硬件板卡抓取的ICP信元进行分析得到有效的E1 IMA时隙,并对这些E1时隙重新进行交叉、下线,最后通过对每个下线E1时隙上的ICP信元进行分析来实现Iub口的IMA组捆绑猜测。根据3G网无线监测和系统的广泛应用分析表明:该算法具有很好的兼容性和操作性,能适应很多复杂的IMA传输环境,支持IMA组分散传输猜测。

Presented an IMA group binging prediction algorithm based on cross-slot of STM-1 E1,whose core idea are as follows.The first get the effectively E1 IMA time slot under the analysis of ICP cell coming from the hardware board,then re-crossing and dropping these E1 time slots,the last analyzing the ICP cell of each E1 slot to implement IMA group binging prediction algorithm of Iub port.Practice widely in the 3G wireless network monitoring instruments and systems proved that the algorithm is of good compatibility and interoperability,which is adaptation to many complex IMA transmission environments and supporting for IMA group dispersed transmission.
