摘要： 将业务接入与业务控制分离，设计并实现基于M+N结构的业务控制点(SCP)容灾系统。该系统可扩展性和可维护性好、可用性高，且对现网设备和业务影响小。测试及实际应用结果表明，其实现了快速的应用级业务恢复，保证了业务的连续性。可以容忍多个生产SCP同时发生故障并提供业务接管。避免数据备份服务的集中运行，增强了容灾SCP的业务处理能力。

Abstract: A application layer disaster tolerant system of Service Control Point(SCP) based on “M+N” architecture is designed and implemented by separating service access function from service control function. It has good expansibility, high availability, fine maintainability, and small impact on business equipment. The system test and practical application show: the rapid recovery of application level ensures business continuity; multiple points of failure tolerance improves system availability; distribution of data replication enhances the handling capacity of SCP on single equipment.

Key words: wireless intelligent network, service control point, disaster tolerant, M+N architecture, expansibility, high availability
