摘　　要：5G系统架构引入了用户面和控制面分离的技术(CUPS),如果将5G CUPS技术提前引入到4G网络中,能满足EPC核心网的建设需求和解决现有架构存在的问题。因此结合4G核心网的建设需求和CUPS技术的特点,分析CUPS技术在4G移动核心网的应用,包括CUPS技术在现有移动互联网和物联网场景的应用。现场试验的测试结果证明了CUPS技术在4G阶段应用的可行性,该技术在降低时延、减少时延变化等方面具有很好的性能优势。The Control and User Plane Separation(CUPS)is introduced into 5G system architecture.The introduction of 5G CUPS into 4G networks can meet the construction requirements of EPC core networks and deal with the drawbacks in existing architecture.Therefore,combined with the construction requirements of 4G core networks and the technical features of CUPS,the applications of CUPS to 4G core networks are analyzed,including the applications of CUPS to the mobile Internet and the Internet of Things.The testing results on spot verify the technical feasibility of CUPS in 4G.CUPS has the performance advantages in reducing delay and jitter.
