Discussion On Application Of The Integrated Network Carrying Small Citybased On IPRAN

With the rapid development of mobile Internet applications, the demand for bandwidth is growing seriously, which is the construction and development of LTE networks is based on, then the requirement of LTE had significantly changed compared with it in the traditional 2/3G network era.As the traditional bearer network, SDH had played a huge role on the stage of history, but in the new era, large bandwidth and the need of multi-service bring its tough challenge. In contrast, with the character of high cost-effective bandwidth, IP technology is more and more be favored in the development of the network, but it could not provide high reliability and faced the question of OAM. While IPRAN has the advantage of a combination of both, which is based on IP technology.It is applicable to a variety of transmission media, and add to the OAM and QoS mechanism, so it has the perfect realization of the requirements of wireless backhaul.In the thesis, we had analyzed and studied the construction of LTE supporting IPRAN network in Jingdezhen. Firstly, the background of subject and the deficiency of the traditional bearer network technology are briefly described. Then the LTE technology is described, and according to its traffic characterization, we analyzed the comprehensive carrying demand in the new era. And then we introduced the concept and key technology of IPRAN, and compared the two radio carrying technology of IPRAN and PTN. Secondly, we expounds the construction principles of the IPRAN network, and introduces the IPRAN network architecture, network model and IPRAN equipment.Finally, combined with the current situation and demand analysis of LTE and other services in Jingdezhen, we completed network planning and application of IPRAN network in Jingdezhen in the thesis.
