基于Cloud Native全融合5G UDM应用研究

Application Research of Cloud Native-based Fully Converged 5G UDM

电信运营商网络中用户数据管理经历了2G、3G和4G时代的不断发展,随着5G网络的到来,设备网元从HLR到HSS,再到目前的5G标准协议里面的UDM、AUSF、UDR,主要功能就是满足运营商现网2G/3G/4G/VoLTE/5G用户的签约数据存储和鉴权管理,以及不同网元之间的数据交互管理。主要研究了基于消费者“不换卡不换号仅更换手机”享受5G高速业务需求下,现有5G UDM用户数据管理需要哪些价值功能来满足当前及未来2C/2B业务的发展需求,以及各价值功能的详细描述。最后给出了目前中国区5G UDM商用部署的最新情况。

Subscriber data management in telecom operator networks has been developing in the 2G,3G,and 4G eras.With the advent of 5G networks,from HLR to HSS,and then to UDM,AUSF and UDR in the current 5G standard protocol,the main functions of these network elements are to meet the requirements of 2G/3G/4G/VoLTE/5G users'signing data storage and authentication management,as well as data interaction management between different network elements.Under the demand of consumers enjoying 5G high-speed service"without changing SIM cards and MSISDNs,only changing their mobile phones",it describes the value-added functions required by 5G UDM subscriber data management to meet the current and future 2C and 2B service development requirements,and each value function are described in detail as well.Finally,the latest status of 5G UDM commercial deployment in China is provided.
