Abstract
In this paper, a drone based system model and prototype is presented which allows mobile phone users to make Voice over Wi-Fi calls, a.k.a. VoWiFi, while the cellular system is not available or the cellular network signal level is under a pre-defined threshold to meet the quality of service for an IP call. The drone based system consists of a drone equipped with a smart phone main board which establishes a Wi-Fi hotspot network and the user equipment, smartphone capable of making a voice over Wi-Fi calls. The system performance is evaluated based on two major parameters: the Perceptual Evaluation of Speech Quality (PESQ) scoring, and the Received Signal Strength Indicator (RSSI). The relationship between these two important parameters is investigated in real life cellular networks under various conditions.
本文提出了一种基于无人机的系统模型和原型，它允许移动电话用户在蜂窝系统不可用或蜂窝网络信号水平低于预定义阈值的情况下进行Voice over Wi-Fi呼叫，即VoWiFi，以满足IP呼叫的服务质量。基于无人机的系统由配备智能手机主板的无人机组成，该主板可以建立Wi-Fi热点网络，用户设备是能够通过Wi-Fi通话进行语音的智能手机。系统性能基于两个主要参数进行评估:语音质量感知评估(PESQ)评分和接收信号强度指标(RSSI)。在实际的蜂窝网络中，研究了这两个重要参数在各种条件下的关系。
