Method for real-time synchronizing configuration data between element management systems and network elements
First Claim
1. A method for synchronizing configuration data between an Element Management System (EMS) and a Network Element (NE), wherein the configuration data of the NE is divided into a plurality of layers such that different layers comprise different configuration data sets of minimum units, and wherein a minimum unit identifier word is provided for each layer to identify any changes to the configuration data in the layer, the method comprising:
- if the configuration data of the NE is changed, the NE changing the minimum unit identifier word of the layer corresponding to the changed configuration data;
the EMS obtaining the changed minimum unit identifier word from the NE; and
the EMS comparing the obtained minimum unit identifier word with a minimum unit identifier word stored in the EMS to determine which layer is associated with the changed configuration data; and
the EMS synchronizing the changed configuration data of corresponding NE with the EMS;
wherein the minimum unit identifier word comprises;
a sequence number identifier word that identifies a minimum configuration unit item with a sequence number;
a network management table identifier word that is a configuration word and comprises configuration tables of all the network management devices supported by the NE;
a mixed identifier word;
or any combination thereof;
wherein the mixed identifier word comprises a configuration device identifier, a changing time identifier, a configuration item identifier, or any combination thereof.

Abstract
The present invention discloses a method for synchronizing the configuration data between an EMS and a NE, which includes: dividing the configuration data in the NE into several layers so that different configuration data layers include different minimum unit configuration data sets; setting a minimum unit identifier word for each configuration data layer to identify the configuration data changes of the configuration data layer; when the configuration data of the NE is changed, changing the corresponding identifier word and sending a configuration changed event notification to EMSs; after receiving the configuration changed event notification, the EMS synchronizes the configuration data according to the event notification. With the present invention, it is possible to make the EMS effectively monitor and synchronize configuration data with the NE in a real-time manner, so that network management efficiency can be improved.

17. A method comprising:
-
determining whether a configuration data within a network element (NE) comprises a change, wherein the configuration data is divided into a plurality of layers, and wherein each layer is associated with one of a first plurality of words that each identify any changes to the associated layer; determining which EMS has changed the configuration data of the NE; setting an operation user identifier word corresponding to the EMS that changed the configuration data, wherein the first words comprise the operation user identifier word; if the configuration data of the NE is changed, the NE determining which layer is associated with the changed configuration data; changing the first words associated with the layers that comprise the change when the configuration data comprises a change; changing the operation user identifier words comprised in the first words; sending the first words but not the change to an Element Management System (EMS), wherein the EMS compares the first words to a plurality of second words to judge whether the EMS has changed the configuration data, and if not, initiates a synchronization process.
