【摘要】：随着数据流量的指数增长，蜂窝网络运营商面临着一个岌岌可危形势：满足快速增长的流量的同时降低成本并提高每用户平均收入（ARPU）。由于电费占据网络运营商支出的20%~30%，这种形势只会随着移动网络消耗能量费用的增加变得更加严峻。 在本论文中，我们提出了一种叫做细胞缩放的新技术来减少基站的能量消耗。通过细胞缩放技术,基站可以基于用户的位置动态地调整它们的覆盖半径和发射功率。根据用户的位置和信噪比的需求，发射功率可以设置成最小级别。基站从来都不完全关闭。我们首先分析用户在一天之中每个时间段的行为，，因而我们可以建立基站密度和用户密度之间的关系。然后根据在一天之中每个时间段的用户数量的所有信息，我们决定发射功率以满足每个用户的需求和保证服务质量。我们也提出提高基站某些部分的能源利用率，如冷却部分，帮助我们节省高达25%的基站消耗的总能量。 仿真显示，在不降低用户服务质量的前提下，本文提出的算法能够节省高达40%的网络能量消耗。
[Abstract]:With the exponential growth of data traffic, cellular network operators are facing a precarious situation: satisfying the rapid growth of traffic while reducing costs and increasing (ARPU). Per user's average income Since electricity charges account for 20% of network operators' spending, the situation will only become more severe as mobile networks consume more energy. In this paper, we propose a new technique called cell scaling to reduce the energy consumption of base stations. By cell scaling, the base station can dynamically adjust their coverage radius and transmit power based on the user's position. According to the user's position and the demand of SNR, the transmit power can be set to the minimum level. Base stations are never completely shut down. We first analyze the behavior of users at every time of the day, so we can establish the relationship between base station density and user density. Then, based on all the information about the number of users in each time of day, we decide to transmit power to meet the needs of each user and ensure the quality of service. We also propose to increase the energy efficiency of some parts of the base station, such as the cooling part, to help us save up to 25% of the total energy consumed by the base station. Simulation results show that the proposed algorithm can save up to 40% of network energy consumption without reducing the QoS of users.
