随着2009年1月7日,工业和信息化部3张3G牌照的正式下发以及三大电信运营商的重组,再度引发了各大运营商3G网络建设的热潮。作为业务承载网络的传输网,必须要先于业务网络的建设而建设。因此,如何满足3G业务的传送,成为电信运营商建设传输网时关注的重点。3G网络及业务的固有特点决定了其承载传输网的特殊需求。通过对3G业务特点、3G传输网特征以及3G传输网建设思路等方面的分析,详细阐述了3G传输网对现有传输网带来的影响以及未来的建设思路。
With the formal issuance of 3 3G licenses by the Ministry of Industry and Information Technology and the reorganization of the three telecom operators on January 7, 2009, the 3G network construction boom of major operators has been triggered again. As the transport network of business bearer network, we must first build the business network. Therefore, how to satisfy the transmission of 3G services has become the focus of attention when telecom operators build transmission networks. The inherent characteristics of 3G networks and services determine the special needs of bearer networks. Through the analysis of the characteristics of 3G services, the characteristics of 3G transmission network and the idea of 3G transmission network construction, the impact of 3G transmission network on existing transmission networks and the future construction ideas are elaborated.
