摘要
Device-to-Device(D2D)通信是下一代(5G)移动网络的重要组成部分。D2D设备间在不依赖基站的情况下直接进行数据传输,并通过重复使用蜂窝小区的频率资源从而提高移动通信系统的容量。为了激励蜂窝网络用户参与到D2D通信,运营商对D2D通信的定价是一个很关键的问题。文中首先介绍了D2D的基本概念及其四种主要类型,并就其中DR-OC型D2D通信定价提出了运营商和D2D设备的收益模型,然后仿真分析了网络中谱单价和奖励带宽对双方收益的影响。仿真结果显示运营商可以通过调整奖励带宽来协调双方收益以激励更多的用户参与到D2D通信。
D2D（Device-to-Device） communication is an important component of 5th generation （5G） mobile network. D2D devices could directly implement data transmission without any reliance on the basestation, and have the potential to increase the system capacity through reuse of the cell frequnecy resource. In order to encourage cellular users to participate in D2D communication, network operators need new pricing strategies of D2D communication. This paper firstly describes the basic concepts of D2D and its four main types, then proposes a earning model for D2D devices and operators in terms of DR-OC D2D communication pricing. And simulation is also conducted to investigate the effects of spectrum unit-price and awarded bandwidth on the revenue for devices and operators. Simulations indicate that the operators could balance the revenue for devices and operators by adjusting awarded bandwidth and thus attract more users to participate in D2D communication.
