The Middleware Of Telecommunication Network Management Based On CORBA Technology

TMN being more and more complex and network functions unceasingly increasing, the management application based on traditional TMN standards comes to show some limitations.These deficiencies encountered in TMN technology, however, can be solved by the application of CORBA technology, a mature distributed object-oriented technology at present.It is predicted that CORBA, in the near future, will be widely used in the fast construction of operations and the effective management of sources in the open telecommunication market environment.According to hierarchy model of TMN, EML needs to provide management interface for NML.In terms of network management interface criterions between NMC and OMC in 3G WCDMA network management established by China Mobile on the basis of CORBA technology, ZTE makes the interface, which can provide manufacture's element management information for superior management network, come true.Management functions of China Mobile northbound interface consist of common management function,safety management function,configuration management function, performance management function and fault management function, where configuration management function concludes basic configuration management function, report of configuration information variation and synchronization function.The basic configuration function mainly deals with conversions of construction, deletion, query and modification in configuration information;When configuration information of network element changes,variation notify of configuration information which is reported from NMC to OMC is fulfilled through conversion of configuration information notify and report function;Configuration information syschronization function synchronizes mass data from OMC to NMC.This thesis introduces design solutions of the middleware of telecommunication network management based on CORBA technology through...
