3G也即是第三代移动通信技术,是指支持高速数据传输的蜂窝移动通讯技术。随着第三代一栋通信技术时代的到来,3G技术也越来月普及。自我国的三张3G牌照发放以来,我国正式步入了3G时代,而基于IP的一系列数据业务也成为了城域网传送的主要部分,同时分组化传输技术就成了下一代数据传送的主流形式。而为了更好的解决光传送网络容量和安全等问题,PTN技术应运而生。随着PTN技术的诞生和在3G传送网中的应用,使得光传送网络容量和安全等问题从根本上得到了解决。而为了进一步提高PTN技术的水平和促进我国3G通信的发展,加大对PTN在3G传送网中应用的分析研究力度不仅意义重大,而且迫在眉睫。本文通过对PTN技术的深入分析研究,然后对其在3G传送网中的应用进行了详细阐述,以供同行探讨。
3G is also the third generation mobile communication technology, which refers to the cellular mobile communication technology that supports high-speed data transmission. With the third generation of a communications technology era, 3G technology is also becoming more popular. Since the issuance of three 3G licenses in our country, China formally entered the 3G era, and a series of data services based on IP have also become the main part of MAN transmission. Meanwhile, the packet transmission technology has become the next generation of data transmission Mainstream form. In order to better solve the problems of optical transmission network capacity and security, PTN technology has emerged. With the birth of PTN technology and the application in 3G transport network, the problems of capacity and security of optical transport network are fundamentally solved. In order to further improve the level of PTN technology and promote the development of 3G communication in China, it is not only significant but also urgent to increase the analysis and research on the application of PTN in 3G transport network. In this paper, through in-depth analysis of PTN technology, and then its application in the 3G transport network were described in detail for peer discussion.
