Calderon Technique Based Integral Equation Methods In Computational Electromagnetics

The GSM network of Zunyi Unicom has been adjusted greatly after the secondphase of the network construction in2010. Only single station optimization and areaoptimization has been done because of limited time However, some other networkproblems emerged frequently later, which affected quality of users’ communication.Competitions of operators is becoming more and more fierce and quality of network iskey to gain more customers and market share. Therefore, network optimism is of greatimportance to operators. The optimization software of Zunyi Unicome GSM network,stated in this paper, is a network optimization estimated system based on PC andWindows NT/2000/XP which has perfect muti-net testing function. The thesis can bedivided into six parts as follows:Chapter1: Introduced the purpose and significance of optimizing Zunyi Unicomenetwork, and the structure of this paper.Chapter2: Elaborated in detail functional and non-functional requirements of thenetwork optimization channel testing system after analyzing the features of ZunyiUnicom GSM network optimization.Chapter3: Designed the overall channel testing system, such as database design,based on demands of Zunyi Unicome GSM network optimization.Chapter4: Presented detailed designing and realization process the Zunyi GSMnetwork optimization software, including the design and implementation of login,GPRS testing, SMS testing, MMS testing.Chapter5: Discussed the test result of the system, procedure of implementations,differences between before and after using it.Chapter6: Summarized the whoel paper, and speculated on the future of GSMnetwork optimization software.My main contribution to this paper is as follows:1, Checked GSM network information of relative regions through thethree-dimensional digital map and a variety of formats map.2, Assessed indoor/outdoor voice quality, data and various value-added services, found out the GSM network problems by the real-time display of testing results.3, Observed the real-time updated data of base stations; connected the originaldata and new data.4, Generated the report automatically according to testing results in the system.
