摘　　要：PCC是运营商构建可管可控智能化管道的重要手段,在4G网络向5G网络快速演进的背景下,PCC架构的演进与部署成为运营商在5G网络部署中需要重点考虑的问题之一。本文阐述了4G/5G PCC架构及其演进路径,并基于当前4G/5G混合组网的现状讨论了PCC架构演进部署方案,最后通过某运营商的PCC部署实践对当前4G/5G混合组网架构下不同业务场景的信令路由方式进行了分析,为后续PCC架构演进和部署提供参考。PCC is an important means for operators to build controllable and intelligent pipelines.In the context of rapid evolution from 4G network to 5G network,the evolution and deployment of PCC architecture has become one of the key issues for operators to consider in 5G network deployment.This paper describes the 4G/5G PCC architecture and its evolution path,and discusses the PCC architecture evolution deployment scheme based on the current situation of 4G/5G hybrid network.Finally,through the PCC deployment practice of an operator,the signaling routing modes of different business scenarios under the current 4G/5G hybrid network architecture are analyzed,which provides a reference for the subsequent PCC architecture evolution and deployment.
