LTE网络中PCC架构的应用

LTE技术是新一代宽带无线移动通信网技术,可大幅提升无线网络业务速率,并采用统一的分组域核心网承载话音和数据业务,而IP网络承载语音等实时业务的质量保证是业界关注的问题。3GPP标准的PCC架构可有效实现LTE网络数据业务差异化的管理和运营,并提供业务端到端的质量保证,是LTE网络中实现语音业务等实时业务的关键。本文对PCC架构以及控制机制进行简要介绍,并结合LTE和PCC技术的发展情况,对PCC在LTE网络中的应用及引入方式进行探讨。

PCC Architecture Applicated in LTE Network

As the next generation technology of mobile telecommunication network,LTE greatly increases the data rates of wireless access network,and provide services including voice and broadband data only via packet core network.OoS guarantee in IP network for carrying voice or other real-time data voices become a key issue in mobile industry.PCC infrastructure defined by 3GPP that suited to meet the end-to-end QoS can be easily tailored to enhance the network performance.This article first introduces the generic PCC...
