Abstract
The present invention discloses a method of providing data redundancy for HLR, the method comprises: performing cutover for subscribers' data preserved in master HLRs into a redundant center HLR; preserving all successfully executed operation & maintenance commands which are associated with system data and said subscribers' data of the master HLRs during runtime of the master HLRs; transferring said operation & maintenance commands preserved in the master HLRs to the redundant center HLR; converting the received operation & maintenance commands into internal operation commands recognizable by the redundant center HLR, and loading them into a host machine of the redundant center HLR. The present invention enhances the conformity of the subscribers' data, and reduces the maintenance workload of the redundant center HLR and lowers the maintenance complexity.
