随着无线多媒体通信技术的发展和终端用户体验期望的提高，满足移动多媒体用户的体验质量要求已成为内容提供商和无线运营商面临的挑战。在本研究中，我们建立了一个对qos敏感的多媒体数据定价经济模型，通过对数据的质量而不是数据的数量进行定价。利用该框架对内容提供商（销售多媒体内容）、无线运营商（提供传输服务）和移动用户（请求多媒体数据）之间的效用最大化问题进行了建模。然后，我们将上述问题表述为两阶段Stackelberg博弈，并使用逆向归纳法推导出纳什均衡。仿真研究表明，当Stackelberg均衡稳定存在时，每个参与人都能获得最优策略。最后，将所提出的智能定价机制与传统的统一定价方案进行了比较，结果表明，利用所提出的方案可以获得更好的效用。
With the advances in wireless multimedia communication technologies and the rise in end- user experience expectations, meeting the Quality of Experience (QoE) requirements of the mobile multimedia user has become challenging for content providers and wireless carriers. In this research, we chalk up a QoE-sensitive multimedia data pricing economic model, by pricing the quality of the data rather than the quantity of the data. Utility maximization problem between the content provider (sells multimedia content), wireless carrier (provides transmission service) and the mobile user (requests multimedia data) is modeled using the proposed framework. We then formulate the aforementioned problem as a two-stage Stackelberg game and derive the Nash Equilibrium using backward induction method. Simulation study show that each player can obtain optimal strategy where the Stackelberg equilibrium exists stably. Finally, the proposed smart pricing mechanism was tested against the traditional uniform pricing scheme and the results indicate that better utilities can be achieved by leveraging the proposed scheme.
