摘要

Packing和Unpacking的过程是AMR/FR与AMR/HR相互转化的一个过程

即内切换速率转化。现网中Packing/Unpacking数多的小区通常小区内切换失败率高

增加掉话风险

同时由于Packing数通常大于Unpacking数

造成Packing/Unpacking数多的小区半速率比例偏高。本文研究的出发点是希望通过对Packing/Unpacking相关机制和参数进行研究

通过合理设置相关参数减少不必要的Packing/Unpacking数

减少掉话风险和半速率占比。

Abstract

The process of packing and unpacking is the transformation of AMR/FR and AMR/HR.In the current real case

the cell with high volume of packing/unpacking also has high handover failure and risk of drop call. Meanwhile

due to the volume of packing is normally higher than the one of unpacking

the cell with high volume of packing/unpacking has relatively higher ratio of half rate.The purpose of this analysis is to decrease the risk of drop call and the ratio of half rate by identifying the correlation of packing and unpacking

and adjusting reasonable relevant parameter to decrease avoidable packing/unpacking.
