Metropolic TD-LTE Braodband Wireless Communication System Design And Research

With the development of mobile communication technology, the urban public mobile network has gradually transited toward the broadband. The new situation brings new challenge to the urban public broadband wireless communication system. As the standard of the fourth generation mobile communication technology, TD-LTE technology supports the current operation and future business of the urban public network by its high data rate, flexible configuration and convenient deployment characteristic spectrum. Therefore, TD-LTE becomes the preferred technology for urban public broadband wireless communication system. At the same time, in the fourth generation mobile communication network construction of a specific city, we need to study and design the networking scheme of TD-LTE to suit the local conditions according to the characteristics of specific scene and specific business requirements, in order to meet the effectiveness of TD-LTE communication network coverage.At first, from the perspective of the necessity and the business need, the design needs of urban TD-LTE broadband wireless communication network system are analyzed in this paper. This analysis provides the design theory and the design ideas for the urban TD-LTE broadband wireless communications network system. Secondly, according to the design principle and objective, the design and deployment of solutions is elaborated on basis of the overall architecture model. And the design of TD-LTE communications fusion networking solutions aimed at covering effectively the urban is achieved. Finally, in the background of TD-LTE communications fusion networking, decision index is designed by analytic hierarchy process after analyzing the necessity of vertical handoff. Then vertical handoff is achieved by multi-attribute decision. The research of urban TD-LTE broadband wireless mobile communication system will improve the urban public mobile network, and strengthen the capacity of mobile operations and customer service. And it also creates significant social benefits.
