Abstract
The invention discloses an incremental data synchronization method, a network element management system and a network management system. The method comprises steps: the network element management system sends an incremental data synchronization request to the network management system when data of the network element management system itself changes; when a response to the incremental data synchronization request by the network management system is received, communication connection with the network management system is built; and on the basis of the communication connection built with the network management system, the network element management system sends the incremental data to the network management system so as to carry out incremental data synchronization on the network management system. as incremental data synchronization is only issued when data of the network element management system change, transmission of invalid data in the case of no incremental data can be effectively avoided, and load of a data transmission port between the network element management system and the network management system can be effectively lessened.

Embodiment
Should be appreciated that specific embodiment described herein, only in order to explain the present invention, is not intended to limit the present invention.
With reference to Fig. 1, it is the particular flow sheet of incremental data synchronous method the first embodiment of the present invention.
It is emphasized that: flow chart shown in Fig. 1 is only a preferred embodiment, those skilled in the art is when knowing, any embodiment building around inventive concept should not depart from the scope containing in following technical scheme:

Below that the present embodiment is progressively realized the synchronous concrete steps of incremental data:
Step S11, Element management system, when the data of self change, sends incremental data synchronization request to network management system.Element management system is preset the time, when reaching Preset Time, and the situation of change of detecting its data.When the data that detect self change, to network management system, send incremental data synchronization request.Described Preset Time is a time interval, can be every 15Min, can be also point between a period of time, and for example, 13:00 or 14:00, do not limit at this.When interarrival time or time point, the situation of change of detecting its data, when having data variation, sends incremental data synchronization request to network management system; When there is no data variation, to the next time interval or next time point, detect again the situation of change of its data.Also can also be the situation of change of detecting real-time its data or when Element management system its data changes, automatically send incremental data synchronization request.
Described incremental data synchronization request comprises incremental data processing instruction, and this incremental data processing instruction comprises the delete instruction of the increase instruction of the data of increase, the replacement instruction of data of variation and/or the data of minimizing.
Described incremental data is the data (classifications such as data, fault data, performance data and secure data are set) that changed after upper subsynchronous or fixed time point, comprises the data of the data of increase, the data of variation and/or minimizing.The data that changed are filtered out and need synchronous incremental data.For example, although having changed, fault data do not need to carry out the similar data such as synchronous.Element management system (EMS, Element Management System) is the system of one or more telecommunication network elements (NE) of management particular type.In general, EMS is managing function and the capacity of each NE, but and ignores the interchange between different N E in network.In order to support the interchange between NE, EMS need to communicate with more higher leveled network management system (NMS, Network Management System).
Step S12, Element management system, when receiving network management system response incremental data synchronization request, establishes a communications link with network management system.
