| 摘 要： | 文章分析了移动通信系统归属位置寄存器(HLR)容灾技术,认为在移动通信系统中,HLR中的用户数据是系统运行的血脉,应通过建设容灾系统,提高HLR网元的业务可用性.文章讨论了设计容灾系统方案应考虑的各种因素:选择同步备份还是异步备份方式,选择1 1配置还是N 1配置方式,采用虚拟卷复制还是硬件复制方式,以及如何设计容灾系统的容量,并给出了具体实施时的指导原则.

| Abstract: | The home location register (HLR) disaster recovery technology is analyzed in the paper. In a mobile communication system, the user data in HLR is regarded to be the blood of the system. Therefore, a disaster recovery is necessarily required to safeguard the services of HLR components. To design a disaster recovery system, various factors should be put into consideration, such as the backup mode (synchronous or asynchronous), configuration mode (1 1 or N 1), recovery mode (virtual volume or hardware), and system volume. Some practical guidelines for the setup of a disaster recovery system are also given. |
