Zhengzhou TD Mobile Wireless Network Research Program

The main contents of this article:In January 2009, the other part of the letter to China Mobile, China Telecom, China Unicom awarded 3G licenses, according to group, "the development of TD-SCDMA, to do everything possible to promote the maturity of TD-SCDMA industry and business development" job requirements around "TD-SCDMA will be a build, operate and evolve as the core of the development of China Mobile and key" development ideas, in accordance with the Department of Public Works approved the letter, including China Mobile was launched in Zhengzhou city, including 28 of the TD-SCDMA to expand the size of two Network Technology Application Test Network building.First, from the macro-policy papers on the description and analysis of China Mobile TD-building networks and the importance of urgency, and China Mobile is currently facing the external environment and internal situation analysis, followed by the three 3G standards from the brief introduction and a comparative analysis of the advantages and disadvantages of the technical level, focusing on the basic concept of TD, the key technology and the status quo.In the demonstration - Design - Implementation - Test - the principle of optimization, from the TD-building wireless network, 2/3G interoperability, field testing and problem analysis of the three aspects.First of all papers presented in Zhengzhou 2G mobile wireless network and network element status quo situation, demonstrated the construction of Zhengzhou TD mobile wireless network, the need for and feasibility of, and to develop a detailed program of the current network upgrade and construction projects objectives, wireless network design specifications, based station subsystem-building programs, HSDPA planning, key resource planning, 2/3G wireless network simulation and interoperability program. Secondly, the thesis of Zhengzhou TD mobile wireless network after the completion of field testing to conduct a detailed analysis, mainly from the voice service, video telephone service, data services, such as the external field test three aspects of the problems found in the analysis, and examples of the voice and video traffic analysis solutions dropped calls. Papers on engineering problems and the experience gained is described, focusing on strategy summed up the network, TD site, such as experience, and for 2/3G interoperability issues that exist in the analysis, examples of how to solve the interoperability the problems that exist, so that TD networks with 2G network as an organic supplement. Papers also HSDPA testing and application of analysis of the example in Henan province TD commercial mobile LTE development and a brief introduction.
