Planning And Application Of IPRAN Transmission Network Of Anshan Uni-com In 4G Era

In recent years, the growth of 3G wireless data traffic has prompted the development of new business which is different from the traditional voice service. From the point of business development, fixed network business data from the original ordinary Internet browsing,email service to the development of video on demand, high-definition television, visual communication, large storage capacity, high bandwidth requirements of cloud computing100 M/ 1000 M, the mobile communication network from the voice communication of the2 G network, Short Message application. development into the 4G multimedia data service,MMS service and other new business needs. From the network reliability, the business model for network stability, network security and QOS also put forward higher requirements. The current operator most of network data network and transmission have independent, so several separate network respectively carry different types of business, which makes the network maintenance relatively tedious and troublesome, but also makes the operating costs increased. Therefore, the MSTP transmission network technology has been unable to meet the high speed data transmission business based on the IPRAN technology transfer network will be born. IPRAN technology is the combination of traditional IP technology and transmission technology. In this paper, the background of the IPRAN technology, the development of the status quo at home and abroad, working principle and so on to explain.Secondly, the key technologies of IPRAN are introduced in detail. And through the contrast,analysis of the advantages and disadvantages of the existing technology. On the basis of analyzing the current development situation of the existing network, this paper classifies and introduces the IPRAN networking mode, and analyzes and compares various networking schemes. Analysis of IPRAN bearing network planning and application of the preparation,networking and related parameters of the hardware facilities, as well as the settings.Anshan Unicom transmission network as an example, according to the Anshan Unicom transmission network to analyze the status quo, to Anshan Unicom IPRAN transmission network planning and to Anshan Unicom IPRAN transmission network planning and application object, according to the IPRAN network architecture and the principle of network planning and research, designed to meet the Anshan Unicom’s IPRAN network, and then in accordance with the networking scheme of IPRAN transmission network planning and implementation, testing and analysis of the operation of the IPRAN network, The quality of service performance, service deployment, service switching time protection test results show that Anshan IPRAN bearing network stable operation. Through service quality comparison before and after the cut-over, It is proved that the IPRAN transport network canmeet the need of multi service more than MSTP. the reliability of IP based wireless access technology. Finally, put forward the deficiency of IPRAN bearing network in Anshan and the development and improvement of the future.
