We study the problem of profit maximization for service providers using a newly emerged business model in millimeter-wave (mmWave) high-speed railway (HSR) networks. In such business model, a service provider purchases data transmission resource from a network operator with a low price. Then, mobile users only need to pay for requested services provided by the service provider. To optimize the profit of service provider, the profit analysis and optimization framework tailored toward the new business model and mmWave HSR networks is developed. This framework consists of three main components including admission control, transmission control, and resource purchasing control. To obtain optimal policies for these components, a stochastic profit optimization problem is formulated while taking into account differentiated service quality requirements, wireless transmission capacity, and network system stability. Then, the formulated problem is solved by using stochastic network optimization theory and stochastic profit maximization mechanism (SPMM) is established. An extensive performance evaluation of SPMM is conducted in order to demonstrate its superiority.
