Research Of Communication Engineering Project Schedule Management Based On Ontology Method

In order to build a 4G network with wide coverage and stable signal,a total of 3.4 million 4G base stations have been built.The engineering construction departments of telecommunications companies constantly optimize the management methods and improve the management efficiency,by summing up the engineering management experience in the 2G and 3G era,and combined with a variety of project management methods and IT technologies.After entering the 5G era,the number of base stations to be built is estimated to be 2-3 times of the 4G era.The heavier commercial tasks of 5G network will be done,the shorter construction period and the higher construction quality will be wanted.It's a new challenges for mobile communication network builders.Studying the advanced management methods during the construction of 4G network is necessary.It will propose better solutions for the 5G era.In this thesis,the Base Station Construction Schedule Management System(BSCSMS)has been studied.It has been built and used in the period of 4G construction.There are some problems in its application.A new technologies demanded to solve the problem of how to apply the knowledge from Management experience,in order to improve the efficiency of schedule management and promote the support ability of application system to the actual business.First,the ontology is selected as the theoretical basis of system optimization.Second,the method of constructing initial ontology based on the database table structure of the original system is proposed.Protégé,as an ontology editing tool,can be used in this method to construct the ontology of base station construction project.Finally,the ontology theory research results and the most advanced technology are applied to realize the knowledge extraction of a large number of historical experience data,and the feasibility of this method is proved by practical application.This thesis looks forward to the management methods of base station construction in 5G era.The improvement direction of base station construction progress management is realized.This dissertation is based on the research of a telecommunications company's actual BSCSMS,and provides reference value for enterprises or organizations engaged in base station construction related projects.
