某地市运营商宽带入网升级改造探讨
摘要
宽带网络是国家信息化的重要基础设施和战略资源,是社会信息化的基础和关键。加强宽带网络建设,可以有效支撑第三代移动通信技术移动宽带和固定宽带业务的发展。宽带接入网是宽带网络最为重要的组成部分,对宽带业务的发展至关重要。为适应未来宽带移动互联网业务发展需要,规范宽带接入网建设工作,必然要求我们进一步发展宽带接入网,全面推进宽带接入网提速项目。
宽带接入网建设是一项长期工作,必须统一规划,量质并重,循序渐进,分步实施,有计划有步骤地推进。宽带接入网涉及面广、技术复杂、投资巨大,为切实满足业务发展需求,避免重复改造,宽带接入网建设应满足3-5年业务需求,适度超前建设。宽带接入网建设应在细分业务发展需求和全面资源核查的基础上,依据发展需求和网络资源状况,制定科学合理的建设方案,提高投资效益。投资应优先满足业务重点城市和业务重点区域。宽带接入网的建设应充分利用现有的网络资源,充分发挥既有资源的协同效应。宽带接入网建设还应充分考虑各区域业务发展、网络资源的差异以及投资承受能力,根据业务需求的轻重缓急,因地制宜地实施差异化的发展策略和建设模式。接入网线路设备应具备良好的扩展性、平滑演进性和可维护性,能够平滑向下一代网络演进。
本课题研究的主要内容涉及以下三个方面：一是对厦门联通公司现有的宽带接入网进行分析研究,找出制约宽带提速的因素,明确现网升级存在的技术限制；二是结合厦门联通公司的现有资源,在满足业务发展需求及公司成本控制要求的基础上,研究制定厦门联通公司宽带接入网升级提速方案,即在厦门联通公司宽带接入网中引入无源光网络技术来达到接入速率提升的业务需求；三是研究在宽带接入网中组建无源光网络的技术细节及制定实施规范。
Broadband network is an important infrastructure and strategic resources of national informatization, and is the basis and the key of social informatization. To strengthen the broadband network construction will support the development of 3G mobile broadband and the fixed broadband business effectively. Broadband access network, the most important part of the broadband network, is vital to broadband business development. In order to meet the future needs of broadband mobile internet business development, and to make broadband access network construction conforming to the standard, inevitably we will be required to further develop the broadband access network, and then promote the project of broadband access network speed up in the round.
Broadband access network construction is a long-term work, which must be planned unitedly, emphasized the amount and the quality simultaneity, promoted in a planned step manner, on gradual step by step. Broadband access network covers a wide range, with complex technology and huge investment. In order to effectively meet the needs of business development, to avoid repeated transformation, broadband access network construction should meet the business needs during 3-5 years, and then moderately, build ahead. Broadband Access Network-building, on the basis of fractionizing the business development needs and a comprehensive verification of resource, should develop a scientific rational building-program according to the development needs and status of network resources, and at last, improving investment returns. Business investment should give priority to the key areas and cities in businesses. The construction of broadband access network should make full use of existing network resources, and give full play to the synergies existing resources. Broadband access network construction also should take full account of the regional business development, the different network resources and the capacity of investment. According to business needs, priorities and local conditions, the development strategy and construction models should be diversity. The equipment of access network should have good scalability, smooth evolution and maintainability, which can be smooth to the next generation network evolution.
The main content of this research project involves the following three aspects:First, analyse Xiamen Unicorn's existing broadband access network to identify the factors constraining broadband speed, and ascertain the technical constraints to upgrading existing network; Second, in meeting the needs of business development and the cost-control requirements from corporate, combining Xiamen Unicom's existing resources, study and formulate Xiamen Unicom broadband access network upgrading-accelerating program, namely, Xiamen Unicom broadband access network will introduce PON technologies to enhance the business needs of accelerating the access speed; Third, study the technical details of forming PON in broadband access network, and develop the implementary specifications.
