【摘要】 当今是信息大发展的时代,不同种类的通信业务如雨后春笋般快速发展,各种综合网络业务的出现也对于不同用户需要提供了更加丰富的选择,在这个基础上,新型IP化网络传输结构已成为各大网络运营商未来发展建设的趋势。而移动终端的迅猛发展也导致了移动网络的IP化进程已成为这个网络架构首先需要建设完成环节。IP成为了移动网络的重要组成部分,更加是移动网络的重要组成部分。IPRAN中的IP指的是互联协议,RAN指的是Radio Access Network。是一种基于IP的新型传输网络。这种新型网络技术的基础是自由度很高的的IP通信设计理念,基于成熟稳定度很高的传统路由器结构,已经成为广大移动运营商建设承载网络的重要解决方案。其多业务承载、可接入大容量带宽、超高服务质量保障能力(Qos)、并且采用增强OAM故障检测机制等对网络运行的业务进行全方位的支撑。该组网方式的硬件结构具有灵活的三层路由功能,可以更好地服务员现有移动数据业务,并且顺应当下移动通信网络的发展趋势,也可以满足众多复杂的业务需求。本文结合哈尔滨电信公司现有网络运行情况以及对于未来承载网IP化的网络构建方案产生的背景和对未来发展做了深入的研究,归纳了目前IP化承载网发展的整体思路。其次,主要研究IP运行网络接入理论,涉及网络技术、网络原理和应用现状。然后,根据IP运行网络技术的现状,提出了IP运行访问的理论知识,包括IP运行网络的网络结构和网络方案。从而提出哈尔滨电信IP运行网络的建设方案以及优化方案。基于IP运行技术,构建了满足LTE业务需求的载波网络。在当前IP网络建设完成后,针对网络结构不合理的区域进行优化改造,提高设备成环率,保证网络质量,同时满足未来发展需求的网络升级。同时,为了满足现有城市地区LTE无线网络BBU的集中配置要求,提出了IP运行负荷网络的优化方案,并将IP运行设备置于集中建设方案中。更多还原

【Abstract】 Nowadays is the era of great information development.Different kinds of communication services have mushroomed.The emergence of various integrated network services has also provided more choices for different user needs.On this basis,the new IP network transmission structure has been Become a major network operators the future development trend.The rapid development of mobile terminals also led to the IP network of mobile networks has become the first network architecture need to complete the construction link.more important part of the mobile network.IP in IPRAN refers to the Internet Protocol,Relative to the traditional SDH transport network,IPRAN means: "wireless access network IP" is a new IP-based transport network.This new network technology is based on the high degree of freedom of the IP communication design concept,based on mature and stable high-quality traditional router structure,has become the majority of mobile operators to build an important solution to carry the network.Its multi-service bearer,access to large-capacity bandwidth,high quality of service(Qos),and the use of enhanced OAM fault detection mechanism for network operation of the business all-round support.The network structure of the hardware structure with flexible three-tier routing capabilities to better serve the existing mobile data services,and comply with the current trend of mobile communications networks,but also can meet a large number of complex business needs.Based on the existing network operation of Harbin Telecom Company and the background and future development of network construction scheme of future carrier network IP,this paper summarizes the current situation of IP network based access technology.Secondly,the main research IP access network operating theory,involving network technology,network theory and application status quo.Then,based on the status quo of IP running network technology,the theoretical knowledge of IP running access is proposed,including the network structure and network scheme of IP running network.Starting from the IP network planning,defined the construction of Harbin Telecom IP network construction.Based on the IP operation technology,a carrier network that meets the requirements of the LTE service is constructed.After the current IP network construction is completed,throughthe independent performance testing of routing equipment and LTE base station service engineering test,the feasibility scheme and network scalability of the IP operation network are verified.Each area network operates stably with good effect and meets the future development Need to upgrade the bearing network.At the same time,in order to meet the centralized configuration requirements of BBUs in existing wireless networks in urban areas,an optimization scheme of IP operation load network is put forward,and the IP operation equipment is placed in the centralized construction scheme.更多还原
