【摘要】:伴随着移动通信技术的高速发展,TD-LTE作为公网4G通信的标准,已经得到了成熟的大规模商用,并得到了国家战略层面的大力支持,而今天无线专网领域却依然以窄带数字集群为主,严重滞后于公网的发展,目前各个专网厂家已经意识到宽带集群的重要性,无线专网选择4G已经成为行业的共识。但是由于专网行业分布特点,特别是中小企业呈现出局部覆盖范围小、上行数据流量大、安装配套环境恶劣、定制要求多等许多突出问题,传统的公网LTE厂商的分布式基站设备直接改造频率,转变成专网基站已经无法满足中小企业的需求。针对专网LTE分布式基站的各种弊端,本文提出对一体化LTE宏蜂窝基站的进行相关研究,改进分布式基站配套要求高、性价比低的问题,在基站结构和可行性方面进行相关论证和对比,从而证明在中小企业有一定的实用价值。课题研究内容主要有以下三个方面:(1)本文首先对专网行业进行的发展进行分析,阐述中小企业在专网领域的应用特点和关注点,以及国内外研究的现状进行了概述,提出将专网4G基站以小型化、一体化、简单化,宏蜂窝的架构来进行针对性开发,满足中小企业的专网需求。(2)然后,对一体化TD-LTE宏蜂窝基站的架构从硬件、软件和OMC网管三个方面的处理流程框架进行研究,论证项目的可行性。(3)最后,针对专网行业中典型的应用-驾驶员科目三考试,从网络设计、工程施工、数据测试方面验证了本系统的有效性和可行性,测试结果证明,系统满足了中小企业客户的实际需求,同时具有很强的实用价值和商业价值。
[Abstract]:With the rapid development of mobile communication technology, TD-LTE as the public network 4G communication standard, has been mature large-scale commercial, and has been vigorously supported by the national strategic level. Today, however, the wireless private network is still dominated by narrowband digital trunking, which lags behind the development of public network seriously. At present, the manufacturers of private networks have realized the importance of broadband trunking. The choice of 4G in wireless private network has become the consensus of the industry. However, due to the characteristics of private network industry distribution, especially the small and medium-sized enterprises show a small local coverage, the uplink data flow is large, and the installation and supporting environment is bad. There are many outstanding problems, such as customization requirements, and so on. Traditional LTE manufacturers directly transform the frequency of distributed base station equipment into private network base station can no longer meet the needs of small and medium-sized enterprises. In view of the disadvantages of private network LTE distributed base station, This paper puts forward the related research of integrated LTE macrocellular base station, and improves the problem of high matching requirement and low performance-price ratio of distributed base station, and demonstrates and compares the structure and feasibility of the base station. This paper first analyzes the development of the private network industry, expounds the characteristics and concerns of the application of small and medium-sized enterprises in the field of private network. And the current situation of domestic and foreign research is summarized. It is proposed that the 4G base station of the private network should be developed by miniaturization, integration, simplification and macrocellular architecture to meet the special network demand of small and medium-sized enterprises. This paper studies the architecture of integrated TD-LTE macrocellular base station from three aspects of hardware, software and OMC network management, and proves the feasibility of the project. Finally, aiming at the typical application-driver subject three examination in the special network industry, The effectiveness and feasibility of the system are verified from the aspects of network design, engineering construction and data testing. The test results show that the system meets the actual needs of small and medium-sized enterprises, and has strong practical and commercial value.
