Database synchronization apparatus in element management system and method therefor
First Claim
1. An apparatus for database synchronization in a network comprising:
- at least one or more network elements which compare block units of information in a common memory storing current status information and information in a sync-related memory storing previous status information, the at least one or more network elements transmitting data results of the comparison; and
a network element management system which stores the data results of the comparison transmitted from the network elements for thereby monitoring and managing the network elements in real time.

Abstract
The present disclosure relates to a database (DB) synchronization apparatus of a transmission network system which includes a plurality of network elements (NEs) and an Element Management System (EMS). Each of the NEs may include a common memory in which DB information and alarm state information are rearranged and a sync-related memory of the same pattern as the common memory for maintaining DB identity with the EMS. The EMS may include a EMS sync-related memory for storing the DB and the information of the sync-related memory of the plurality of NEs, and a EMS common memory corresponding to the common memory (CM) of the NE. A common memory which reflects database information and the current alarm information to the NEs, and a sync-related memory which stores data prior to a T-second period are built on the NEs, and these two memories are compared in block units to thereafter transmit only modified block data to the EMS. Accordingly, there is the advantage that since synchronization is established by the comparison of the memories, an initialization execution time is very fast, and a real-time data monitoring and management is convenient.

7. In a network which is provided with at least one or more network elements, a method for database synchronization in the network comprising the steps of:
-
comparing block units of information in a common memory which reflects database information of said network elements with block units of information in a sync-related memory which stores data prior to a certain period; transmitting only modified block data, as a result of said comparison, to said network element management system; and storing said transmitted data in the memory of the network element management system. - View Dependent Claims (8, 9, 10, 11, 12, 13, 14, 15, 16, 18)

19. A data synchronization method comprising:
-
comparing blocks of information in a common memory of a network element with blocks of information in a sync-related memory of the network element; transmitting data from the network element to a management system based on the comparison; and storing the transmitted information in the management system. - View Dependent Claims (20, 21, 22)
