摘要
为了实现4G/5G互操作,5G核心网的用户签约数据库UDM和策略数据库PCF必须分别与4G核心网的HSS和PCRF融合建设,基于5G的组网需求和2G/3G/4G的网络部署经验,梳理了几种可行的数据库组网方案,分析了5G网络的数据库组网需要从用户不换卡不换号的开通需求、数据库融合、4G数据迁移、网络路由等多个方面来考虑技术方案,从而保证4G用户升级为5G用户的业务体验。
In order to achieve 4G/5G interoperability, the UDM of user subscription database and the PCF of policy database in 5G core networks should be integrated with the HSS and PCRF in 4G core networks, respectively. Based on 5G networking requirements and 2G/3G/4G network deployment experience, this paper provides several feasible database networking solutions. The technical solutions for database networking in 5G networks are analyzed in terms of subscriber provisioning requirements without changing card and number, database fusion, 4G data migration, and network routing. Hence the service experience of upgrading 4G users to 5G users is guaranteed.
