摘要

安装备用电源在维持通信服务方面起着至关重要的作用,在自然灾害期间可以节省数十亿美元和人命。由于与公共电力相比,备用电源的资本和运营成本更高,因此,由于备用电源容量可以根据共址运营商的总需求进行调整,因此集中和共享备用电源可能是一种经济的解决方案。然而,由于容量有限,用户需求高,如何在多运营商蜂窝站点公平地汇集和共享备用电源是必须考虑的问题。本文采用能保证备用电源共享公平性的议价问题的纳什议价解(NBS),设计了一种算子间信息交换有限的去中心化算法。仿真结果表明,与非共享方式相比,共享备用电源降低了平均延迟,并且所需的BS功耗更小,特别是在高流量负载场景下。此外,我们也将公式扩展到交通需求非常大的情况下的准入控制。

Multi-operator backup power sharing in wireless base stations
Installation of backup power supply plays a vital role in maintaining communication services which can save billions of dollars as well as human lives during natural disasters. Due to the higher capital and operational expense compared to public power, pooling and sharing the backup power supplies can be an economical solution since the backup power capacity can be sized based on the aggregate demand of co-located operators. However, how to pool and share the backup power at multi-operator cellular sites in a fair manner should be considered due to the limited capacity and high user demands. In this paper, we adopt the Nash Bargaining Solution (NBS) of a bargaining problem which can guarantee the fairness of backup power sharing and design a decentralized algorithm approach with lim­ited information exchange among the operators. Our simulation demonstrates that the sharing the backup power reduces the average delay and requires less BS power consumption than the non-sharing approach, especially for high traffic load scenarios. In addition, we also extend the formulation with respect to admission control for very high traffic demand cases.
