摘要: LTE(Long Term Evolution,长期演进计划),以其卓越的通信带宽、高频谱利用率、可靠的Qos保证、灵活的系统部署、低网络时延成为电信运营商演进网络的首选。目前90%以上的运营商对LTE-TDD或者LTE-FDD表现出不同程度的关注。然而,LTE的扁平化理念在引入传统网元时受到挑战。依据扁平化理论对LTE核心网中的EIR(Equipment Identity Evolution,设备识别寄存器)和PCRF(策略和计费规则功能)提出一种融合的扁平化演进策略,在系统实验中起到一定降低时延的效果。

Abstract: LTE becomes the best choice of the evolution of the telecommunications network, with its excellent bandwidth communication, high spectral efficiency, Qos, flexible deployment, lower network delay. 90% of operators show varying degrees of concern with LTE. However, in the introduction of flat idea in traditional network elements, LTE faces challenges. Based on LTE flat theory, this paper presents a fusion evolution strategy of EIR(Equipment Identity Evolution) and PCRF. In the system test, it shows effect in reducing delay.
