Dual strucuter device for the main control device in the UMTS RNC and controlling method therefore

摘要

invention RNC (Radio network controller) of the backboard via redundant processors of each of the PCI (Peripheral component interconnect) Bus and a separate paths to connect the external device and data transmission and reception process UTOPIA (Universal test and operations PHY interface for ATM) Buses and, 100base-T ethernet connected via redundant paths separately built to run the dump data transfer tasks to make the initial drive to dump the contents of their memory to deliver data to the active to standby through the redundant paths and a processor which is driven, by receiving data in the UTOPIA identical with the active processor from the external equipment through the bus creates a hash management table and comparing the processed data stored in the hash table and the data sent from the active unit to the message processor to drive the error the structure provides a redundant device and a control method for the main control device consisting of a UMTS RNC to the standby processor is driven to avoid. ; The present invention as described above is to receive external data, in addition to PCI bus architecture If that can be configured by the UTOPIA bus to receive the external data stored in the hash table through which a standby processors as in the active processor, and not the error data compared with the hash table, the data received from the active unit to the message processor only processes By storing the information, and avoid the duplication of the RNC dual processor down to be.
