中文摘要：

依据电信网络建设、运营管理的实践经验，总结、抽象小区接入网络模式；分析小区接入网络建往、运营的主要成本构成，按照运营商实施小区接入网络工程规范和当前价格水平，测算不同接入网络模式的覆盖成本、设备端口成本、用户接入成本、维护服务成本和本地网间结算成本数据；以投资回收期为目标，建立小区接入网络模式的分析模型，测算各种模式下的投资回收期；基于弹性函数方法，分析投资回收期时用户占有率、维护服务成本、覆盖成本、设备成本等相关参数的敏感性。

英文摘要：

According to the experience having telecommunication networking and running management, the model of community access network was summarized and abstracted; It is analyzed that the prime cost about networking, running in the community, The cover cost, equipment port cost, user access cost, service cost, pay cost to other operator were calculated according to the project norm and current price of community access network; The investment payback period was aimed. The analysis mode of the model of community access network was set up. And the investment payback period was calculated with the various model; Based on the method of elastic function, The sensitiveness was analyzed with the investment payback period to the parameter separately, such as occupation rate, service cost, cover cost, equipment port cost, etc.
