无线核心网的TCO分析方法研究

[摘要] 基于通信行业的总体拥有成本（TCO）模型和核心网的特殊性，提出了无线核心网专有的TCO模型。该模型的特殊性包括：互联互通测试费用的复杂性、培训费用的必要性。通过引入新供应商的决策场景，采用成本项纳入工作流的分析方法，提出以人力投入成本和时间为主要度量手段的TCO定量度量方法。通过新老供应商并存场景的分析，指出业务部署和运维会对TCO产生复杂的影响。

[Abstract] Based on the model of total cost of ownership (TCO) in the communication industry and the special nature of core networks, the TCO model of wireless core network is put forward. The drawbacks of the model include complex interconnection testing and training cost. By introducing the decision scene of new supplier's, and adopting the analysis method in which cost items are included in the workflow, the TCO quantitative measurement method based on human input cost and time as the main measure method is put forward. Through analysis on the scene which includes the new and old vendors, it is pointed out that business deployment and operation and maintenance have a complex effect on TCO.
