分布式HSS容灾组网分析

Analysis of the Distributed HSS Disaster Recovery Network

HSS是下一代通信系统核心网的主要网元,其主要作用是实现用户管理功能,存储用户开户信息(业务签约数据和用户状态)、用户位置信息、用户标识等。分布式HSS从物理设备上划分为BE(Back End)和FE(Front End)两部分,实现用户数据与业务逻辑处理的分离。文中对HSS设备组网、设备容灾及数据容灾的实现、存在的问题及建议等方面进行总结分析,阐述HSS容灾的重要性及解决方法。

HSS is the major network element in the next generation of communication system core network,whose main functions are achieving user management function,storing user account information(business contract data and user status),including user location information and user tags,etc.Distributed HSS is divided into two parts of BE(Back End)and FE(Front End),which realize the separation of user data and processing business service.This article mainly summarizes and analyzes the realization,existing problems,suggestions and other aspects of HSS network equipment,equipment for disaster recovery and data disaster recovery system in order to elaborate the significance and solution to HSS disaster recovery.
