【摘要】 针对用户驻地网建设投入高、收效慢、不确定因素多和投资风险大的特点,通过建立用户驻地网接入模型,作为电信运营企业在驻地网建设投资决策中的重要参考依据,并指导其驻地网建设。给出了用户驻地网所采用的3种主要有线接入模式:光纤+LAN(Local Area Network)、ADSL(Asymm etrical D igital SubscriberL ine)及CMTS(Cab leModem Term inal System),并就3种模式进行了投资估算分析,建立投资估算分析模型。在此基础上针对不同规模小区驻地网,对3种接入模式进行了投资与收入分析研究,并建立了不同规模小区的投资/收入与实装用户模型。分析了3种接入模式盈亏平衡点的装机率、投资与实装用户关系、装机率与接入模式的关系以及3种接入模式的优缺点。更多还原

【Abstract】 As there are characters such as heavily investment,slowly effects,uncertain factors and the risk of investment in the customer Premise network,models are built up to be analyzed and conclusions are references for decision-making.Three prime wire access manners are introduced as followed,optical fibre+LAN(Local Area Network),ADSL(Asymmetrical Digital Subscriber Line) and CMTS(Cable Modem Terminal System).The investment in the three models is the base of analysis on investment comparing to revenue in different communities,and the model of the relationship between the number of users and the residents is built up.In the end,we brought forward the turning point of the rate of users-accessed in the three access modes,the relationship between investment and the number of users,the relationship between the rate of users-accessed and the access modes and the merits and shortcoming of the three access modes in technology and economy.更多还原
