Always-on mobile users need high bandwidth channels with negligible access delay and limited power consumption. Such a continuous connectivity mode requires the management of high-speed channels, which can turn into substantial operational costs (i.e., power consumption rate) even in presence of low traffic, unless a power saving mechanism is enforced. In this paper, the authors analyze the impact of 3GPP-defined power saving mechanisms on the performance of users with continuous connectivity. They develop a model for packet transmission and operational costs.
