Abstract

A core network of UMTS has a very long development. The first version of core network corresponds to an improved GSM/GPRS core network. The interfaces are changed and later all conception. The main changes are in using Internet Protocol, adding IMS functionality and finally in complete new packet core of technology called long term evolution. From user point of view it means increasing bit rates from tens kbit/s to tens Mbit/s, offering multimedia services, access to Internet, etc. This paper gives an overview about evolution of UMTS core network.
3GPP核心网演进
UMTS的核心网有很长的发展历程。第一版核心网对应于改进的GSM/GPRS核心网。接口改变了,后来所有的概念都改变了。主要的变化是使用互联网协议,增加IMS功能,最后是称为长期演进的全新分组核心技术。从用户的角度来看,它意味着将比特率从几十千比特/秒提高到几十兆比特/秒,提供多媒体服务,接入互联网等。本文对UMTS核心网的演进进行了综述。
