Problems solved by technology

But the disadvantage is that in the case where there is a large amount of configuration data in the EMS, the synchronization of all data may lead to overloading of the EMS and the interface between the NMS and the EMS, triggering other problems such as NMS or EMS system instability, communication disconnection, and synchronization failure.
[0005] At present, the industry has realized the defects of the full data synchronization method. In order to reduce the interface load, the requirement for incremental data synchronization has been proposed in the relevant OMC northbound interface standards, but there is no definite solution, mainly because there is no better incremental In the data generation method, if the NMS tells all the data to the EMS in reverse, and the EMS completes the full comparison of the original data to form incremental data, then the computational complexity and time cost will be very huge, which obviously cannot effectively solve the problem of rapid incremental data. generate

Embodiment Construction

[0031] Preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0032] The processing process of the southbound interface is described in detail with reference to FIG. 1 , FIG. 2 and FIG. 3 .

[0033] As shown in Figure 1, 1, 2, 5, ..., M on the NE side represent the serial number, each serial number corresponds to a corresponding data, and the serial number of the NE is allocated and transmitted by the EMS. 1, 2, 6, ..., M on the EMS side represent serial numbers, and each serial number corresponds to a corresponding data.

[0034] As shown in Figure 2, the processing process of the southbound interface is as follows:

[0035] 1. The NE initiates a synchronization operation to the EMS.

[0036] 2. When synchronizing for the first time, EMS sends all data to NE, and sends all serial numbers and corresponding data for synchronization.

[0037] 3. The NE initiates a synchronization request to the EMS.

Abstract

The invention discloses an incremental data creation method based on running numbers. NE initiates synchronous request and sends all running numbers to EMS, which traverses the running numbers thereof and the running numbers sent by NE and generates incremental data after comparison. EMS sends the deleted running numbers to NE, which will delete the data to be deleted after receiving the running numbers; EMS sends the data of increment and modification and sends the running numbers of increment and NE will increase data and modify data according to the receipt information. The invention is particularly applicable to north bound interface and south bound interface in 3GPP network management system and realizes synchronization by the incremental data needed in synchronous data creation. The invention can generate incremental data by running numbers quickly, adopt incremental data synchronization, synchronize the variational deployment data only (including addition, deletion and modification), and reduce synchronized data amount and inflow rate load of interface in long term maintenance management.

Description

technical field [0001] The invention relates to a method for generating required synchronous data in a network management system, in particular to a method for generating required synchronous data in a 3GPP network management system. Background technique [0002] In the 3rd Generation Partnership Project (3rd Generation Partnership Project, 3GPP), the interface between the network management system (EMS) and the network element (NE) is called an Inf-S (southbound) interface. The interface between the network management system (NMS) and the network element management system (EMS) is called the Inf-N (northbound) interface. [0003] In order to ensure the effective management of the communication network, the data between the EMS and the NE needs to be consistent. In the existing system, the configuration data synchronization mode between the EMS and the NE is divided into a full data synchronization mode and an incremental data synchronization mode, and the full data synchro...
