  Abstract

High reliability and real-time response are required in the Main Control Processor of Radio Network Controller for IMT-2000. In spite of its robustness some fault rates is inevitable, so the processors are duplicated for non-interrupted service and services are switched to the standby processor in case of faults. The hot-standby sharing scheme has advantages of no data loss and non-proliferation of error data in comparison with the warm-standby sharing scheme but it has difficulties with implementation due to synchronization problem. This paper proposes an expanded warm-standby sharing scheme based on a novel massage processing and error detection mechanism for improving performances.
