Problems solved by technology

Since the NMS cannot predict the amount of changed data when it initiates incremental synchronization, this method may cause the NMS to wait too long for a response when there is a large amount of changed configuration data in the EMS, and even cause the EMS to be overloaded
Another disadvantage is that since the NMS usually sets a waiting timeout period during the implementation process, when the EMS system is busy or there is a lot of configuration data to be synchronized, the incremental synchronization may fail due to the timeout

Embodiment Construction

[0014] According to the embodiment of the present invention, the incremental synchronization between the NMS and the EMS adopts an asynchronous synchronization mechanism, that is, after the EMS receives the incremental synchronization request from the NMS, it judges whether to accept the request according to its own situation (such as whether there are multiple synchronization tasks). Request, if the request is accepted, immediately respond with a request success message. After the EMS sends a successful response message, it can usually prepare and report the changed data immediately. There may be multiple ways of reporting transmission, and the embodiment of the present invention provides the ways of file transmission and message transmission as an illustration.

[0015] As shown in FIG. 1, it is a flowchart of an asynchronous incremental synchronization method according to an embodiment of the present invention, including the following steps:

Abstract

The disclosed data increment synchronization method between network management system (NMS) and net element management system (EMS) comprises: first, NMS sends increment synchronization request to EMS to require latter transmit data increment; EMS decides whether accepts the synchronization request and returns success or failure response to NMS; for success response, the EMS reports the data increment to NMS. This invention reduces data quantity and flow load, and applies asynchronic way to avoid failure led overtime waiting.

Description

technical field [0001] The invention relates to the field of mobile communication, in particular to a data synchronization method between a network management system and a network element management system. Background technique [0002] The interface between the network management system (NMS) and the network element management system (EMS) is called Itf-N interface. EMS mainly completes the network element management layer (EML) function in ITU TMN, that is, completes the management function of one or more mobile communication devices. Usually, EMS between different equipment suppliers cannot be used universally. NMS mainly completes the network management layer (NML) function in ITU TMN, and is responsible for the management of all network elements in a managed network. For the situation that there are multiple equipment suppliers in the managed network (called a subnet), the purpose of managing the entire subnet can be achieved through EMS management. [0003] In order ...
