Handover Mechanisms for Planned Cell Outage in Twin State Green Wireless Networks

This paper investigates possible handover mechanisms for a twin state network aimed at energy saving. We propose the twin state network as a viable ´Green´ option and illustrate the possible energy savings. The challenge of conducting multiple handovers within the transit times of the twin state network, while maintaining the service quality is discussed. The possible handover solutions through multi-carrier operation, FFR and incremental coverage extension are presented in the context of LTE standards.
