【摘要】：传统的移动承载网网络是基于TDM/SDH建成的,对于颗粒度较小、带宽需求不大的业务如2G基站,TDM/SDH都能满足网络发展的需求,但是随着3G和LTE等系统的部署与发展,数据业务已成为承载主体,其对带宽的需求在迅猛增长。SDH传统的TDM独享管道的网络扩容模式难以支撑,分组化的承载网建设已经成为一种不可逆转的趋势。在此背景下,中国电信集团选择了IP RAN技术建设移动承载网络。本文首先介绍了移动承载网络面临的形势及未来发展趋势,分析了IP RAN技术的优势和特点。对宁夏电信省内IP RAN网络现状进行了分析,对基站承载需求、业务传输带宽需求进行了预测。本文重点对宁夏电信省内IP RAN网络建设方法进行了设计,结合IP RAN网络的特点,给出了宁夏电信基于IP RAN技术的移动承载网方案,包括3层(核心层、汇聚层和接入层)的组网结构、节点的设置、A类与B类设备的互连方式、三层路由的设置、IP地址配置和VPN部署策略等。最后对IP RAN的综合业务承载进行了分析,对后期政企业务割接至IP RAN网络承载进行了设计。
[Abstract]:The traditional mobile bearer network is built based on TDM/SDH. For services with small granularity and low bandwidth requirement, such as 2G base station, TDM/SDH can meet the needs of network development. However, with the deployment and development of 3G and LTE systems, Data service has become the main carrier, and its demand for bandwidth is growing rapidly. The traditional TDM network expansion mode of SDH is difficult to support, and the construction of packetized bearer network has become an irreversible trend. In this context, China Telecom Group chose IP RAN technology to build mobile bearer network. This paper first introduces the situation and future development trend of mobile bearer network, and analyzes the advantages and characteristics of IP RAN technology. The present situation of IP RAN network in Ningxia telecom province is analyzed, and the demand of base station carrying capacity and service transmission bandwidth is forecasted. This paper focuses on the design of the construction method of IP RAN network in Ningxia Telecom province. According to the characteristics of IP RAN network, this paper gives the mobile carrying network scheme of Ningxia Telecom based on IP RAN technology, which includes three layers (core layer, core layer). The network structure of convergence layer and access layer, the setting of nodes, the interconnection mode between class A and class B devices, the setting of three-layer routing, the configuration of IP address and the policy of VPN deployment, etc. Finally, the comprehensive service carrying capacity of IP RAN is analyzed, and the design of the later government business cutting to IP RAN network carrying capacity is carried out.
