Impact of Dynamic Planning on Uplink Service Quality in Heterogeneous Cellular Networks Conference Paper uri icon

abstract

  • © 2016 IEEE. In literature, dynamic planning (base station (BS) on-off switching) is proposed as an efficient approach for energy saving at a low call traffic load condition. All related research efforts aim to employ dynamic planning to save energy for the network operators while satisfying the quality-of-service (QoS) for downlink mobile users. On the other hand, although switching off a BS can save energy for network operators and satisfy the downlink QoS, it may lead to associating uplink mobile users with a faraway BS, and hence, degrade the uplink QoS. Such an impact of dynamic planning on uplink service quality is not well investigated in literature. In this paper, we aim to quantify this impact by considering two QoS metrics, namely, user required throughput and call dropping probability due to mobile terminal battery depletion for uplink data calls. Simulation results demonstrate that BS switching off decisions that do not account for the uplink QoS requirements can result in severe service quality degradation.
