近年来，智能手机和移动的应用程序的普及经历了相当大的增长，预计这种增长将在未来继续。由于智能手机的能源非常有限，因此电池效率是良好用户体验的决定因素之一。因此，一些智能手机在完成数据传输后不久就断开与移动的网络的连接，以降低其传输单元的功耗。然而，由发送或接收少量数据的应用引起的频繁连接重建通常导致移动的网络内的沉重信令负载。本文的主要贡献之一是在智能手机和所产生的信令流量在移动的网络中的能源消耗之间的权衡的调查。我们解释说，这种权衡可以通过连接释放超时来控制，并研究此参数对一些流行应用程序的影响，这些应用程序涵盖了带宽要求和由此产生的信令流量方面的各种流量特征。最后，我们研究了定时器设置对Web流量体验质量（QoE）的影响。这是一个重要的方面，因为连接建立不仅导致信令业务，而且增加了网页的加载时间。
The popularity of smartphones and mobile applications has experienced a considerable growth during the recent years, and this growth is expected to continue in the future. Since smartphones have only very limited energy resources, battery efficiency is one of the determining factors for a good user experience. Therefore, some smartphones tear down connectionsto the mobile network soon after a completed data transmission to reduce the power consumption of their transmission unit. However, frequent connection reestablishments caused by apps which send or receive small amounts of data often lead to a heavy signalling load within the mobile network. One of the major contributions of this paper is the investigation of the resulting tradeoff between energy consumption at the smartphone and the generated signalling traffic in the mobile network. We explain that this tradeoff can be controlled by the connection release timeout and study the impact of this parameter for a number of popular apps that cover a wide range of traffic characteristics in terms of bandwidth requirements and resulting signalling traffic. Finally, we study the impact of the timer settings on Quality of Experience (QoE) for web traffic. This is an important aspect since connection establishments not only lead to signalling traffic but also increase the load time of web pages.
