Research on increasing typical data service’s PDCH efficiency
摘要
近年来GSM数据业务占用的信道资源呈快速增长的趋势
但数据业务信道的承载效率却较低。越来越多信道被数据业务占用
势必造成话音业务信道的减少
进而造成TCH信道的拥塞
一定程度上影响了话音质量。如何提升数据业务信道的承载效率
尤其是提升低效数据业务信道的承载效率
降低数据业务信道的占用成为GSM网络发展的重要课题
也是本文的主要研究内容。
Abstract
As the packet data channel(PDCH) increased fastly
the efficiency of PDCH is all keeping a low level.More and more radio channels are occupied by data services
so traffic channels(TCH) are running low and TCH congestion is becoming serious.How to increase the efficiency of PDCH becomes an important point of GSM network and it is also this paper’s central content.
