5G is anticipated in 2020. In this generation of mobile networks, a great deal of requirements have been set. Although, there are many strong technologies in the telecommunications’ sector they do not respond to the 5G goals. On the other hand, telecommunication operators and providers do not want to invest in new equipment/architectures. Cognitive radio (CR) and software defined networking are two technologies with special and vigorous advantages. In this paper, several technical and economic models are developed. The CR is combined with the Stackelberg game. A sensitivity analysis is implemented and the parameters that impact mostly on the model are pinpointed. It is shown that the CR technology could offer all its fundamental cognitive advantages and even financial profits to the telecommunication companies.

5G有望在2020年出现。在这一代移动网络中，已经提出了很多要求。尽管在电信领域有许多强大的技术，但它们并未响应5G目标。另一方面，电信运营商和提供商不想在新设备/架构上进行投资。认知无线电（CR）和软件定义的联网是两项具有特殊和强大优势的技术。在本文中，开发了几种技术和经济模型。CR与Stackelberg游戏结合在一起。进行了敏感性分析，并确定了对模型影响最大的参数。结果表明，CR技术可以为电信公司提供其所有基本的认知优势，甚至可以提供财务利润。
