| The Paper studied in the the Internet of things technology in the mobile operator network optimization and maintenance work when the 5G network is coming soon.Combined with the work of myself in China Mobile Communications Group Yunnan co.,LTD.Kunming Branch Network Department.The Paper studied in IoT network optimization and maintenance work such as various parameters optimization,to improve the efficiency,and the performance of mobile netword.Summarizes the related theory of Internet of things technology research in the application of energy efficiency in the practical work and subsequent development prospect.The main contents of this paper are as follows:1.The Paper first studied the development and market prospects of internet of things technology in current Mobile Operators in China.Predicted in 2020,China will amount to billions of internet connection(including all kinds of connection),industrial market space will up to 1 trillion yuan.In the future,more than 30% of internet connection will be suitable for cellular network load,so it brings enormous challenge for the mobile operators.2.The Paper then studied the mainstream technology of internet of things in China Mobile,NB-IoT(Narrow Band Internet of Things),one kind of narrow-band technology.Combined with the work of myself in China Mobile Communications Group Yunnan co.,LTD.Kunming Branch Network Department,it studies how the Internet of Things become the focus of industry for the operators to actively promote the development.And it studies how the Internet of Things become the leading driving standard industry operators from concept small business,and soon becomes an industry leader.The reasons are mainly based on the advantages of NB-IoT 's realization principles and key technologies,including three spectrums,physical channel,threshold setting of different coverage levels,unique physical layer structure and other key principles.The key technologies including: 20 dB coverage application,low-power PSM/eDRX/ Long suntau technology,low cost of big connection,main equipment deployment mode and antenna construction mode.3.The Paper also studied the idea and scheme fo NB-IoT netrwork optimization of Kunming Mobile.The quality improvement of IoT for Kunming Mobile is limited to the following: less means,huge interference,hard optimization,complicate scene,miscellaneous tools.how to solve these difficulties will become the focus of the optimization and maintenance work.The content of this paper will also work closely with my content,mainly includes the following several aspects:Overview of kunming mobile present NB-IoT network,challenges faced by NB-IoT network,deployment of NB-IoT,introduction of NB–IoT's main equipment manufacturer,and related optimization and maintenance means of NB-IoT.4.Followed by the research,the paper shows the work results of NB-IoT network optimization and maintenance in Kunming Mobile.The results include the test methods and optimization results:the depth coverage and performance test,the planning methods and test environment,the field test situation and analysis,the performance gap analysis of test terminal and frequency sweep meter,outdoor path coverage test,the contrast of penetration loss by fixed-point test indoor and outdoor,the coverage performance from different manufacturers,,and so on.Long-term optimization results show how to improve the efficiency of Kunming Mobile NB–IoT system.5.At the end of the paper,the application of NB–IoT in various scenarios in yunnan province will be briefly discussed,as well as the prospect of subsequent network development,and the route suitable for the network development in the 5G new era of kunming mobile in the future will be looked forward. |
