论文摘要
在这项研究中，调用详细记录（CDR），涵盖布达佩斯，匈牙利已经处理以分析订户的昼夜节律。引入了称为唤醒时间的指标来描述一组订户的行为。它被定义为时间，一个小组的手机活动在早上上升。它的对手是时间，活动在傍晚。还提出了居民和基于地区的聚集。前者是考虑居住在某个地区的人们，后者使用该地区的过境活动来描述城市的行为。购物中心的开放时间和派对区的夜生活被用来证明这一申请，作为现实生活中的例子。建议的方法还用于估计工作场所的工作时间。这些发现与匈牙利的实践达成了良好的一致性，也支持工作场所检测方法。在唤醒时间和移动性指标（熵，回旋半径）之间发现了负相关：在工作日，人们早点醒来，并在节假日旅行更多。使用住房价格和手机价格，在不同的社会经济阶层中评估了唤醒时间。发现较低的社会经济群体倾向于较早醒来。
In this study, Call Detail Records (CDR), covering Budapest, Hungary has been processed to analyze the circadian rhythm of the subscribers. An indicator, called wake-up time, is introduced to describe a behavior of a group of subscribers. It is defined as the time, when the mobile phone activity of a group rises in the morning. Its counterpart is the time, when the activity falls in the evening. Inhabitant and area-based aggregation are also presented. The former is to consider the people who live in an area, the latter uses the transit activity in an area to describe the behavior of a part of the city. The opening hours of the malls and the nightlife of the party district was used to demonstrate this application, as real-life examples. The proposed approach was also used to estimate the working hours of the workplaces. The findings are in a good agreement with practice in Hungary, and also support the workplace detection method. Negative correlation was found between wake-up time and mobility indicators (Entropy, Radius of Gyration): On workdays, people wake up earlier and travel more, on holidays it is quite the contrary. The wake-up time was evaluated in different socioeconomic classes, using housing prices and mobile phones prices, as well. It was found that lower socioeconomic groups tend to wake up earlier.
