摘要：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 connections
to 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.
