Description
小区节能和节能补偿方法及设备 本申请要求在 2013年 3月 28日提交中国专利局、 申请号为 201310105590.X、 发明名 称为"小区节能和节能补偿方法及设备"的中国专利申请的优先权， 其全部内容通过引用结 合在本申请中。
技术领域
本发明涉及无线通信领域， 尤其涉及一种小区节能和节能补偿方法及设备。
背景技术
保护环境和应对气候变化对人类来说是巨大的挑战。 在电信行业， 随着能源消耗的增 长， 更多的运营商开始越来越多的关注他们的社会责任， 当然， 能源价格上涨导致更高的 运营成本也是需要考虑的因素。 在长期演进（Long Term Evolution, LTE ) 网络中， 节能是 一个非常重要的议题， 目前的节能方案还不够完善。
目前， 移动通信网络的节能有以下几种途径：
第一， 在保证覆盖、 容量、 服务盾量不受影响的前提下， 优化站址的数量； 第二， 寻找有效的提高能源利用率和降低设备功耗的方法；
第三， 研究开发可持续能源 （风能、 太阳能等）。
无线接入网 （ Radio Access Network, RAN )侧的设备主要是针对高峰期的需求， 对一 个三扇区的小区来说， 每个扇区有 4个收发机， 这样就有 12个收发机始终处于激活状态， 其实并不需要这样， 如果能够引入能源控制机制， 每一个扇区在业务低峰期 （比如深夜） 只需要保持一个收发机处于待机状态就可以满足业务需求了， 如果所有的基站（eNB )都 能够使用这种节能策略， 那么就可以在不影响服务盾量的前提下节省大量的能源。
对于自优化网络而言， 节能实体大致可分为以下三种结构：
第一， 分布式架构。 网元收集必要的信息进行自优化过程， 不需操作与维护 （OAM ) 实体的参与；
第二， 集中式架构。 OAM从网元收集信息后触发节能算法， 然后决定网元的后续动 作；
第三， 混合式结构。 以上两种方法混合使用。
节能管理（Energy Savings Management, ESM )概念是指优化利用整个或部分网络的 资源利用率。 ESM通过从网络收集和评估相关信息， 发起适当的动作来调整网络配置， 从 而满足服务需求。
节能的方案包含以下两个基本过程：
第一，节能激活：通过关闭 eNB的小区或限制使用部分物理资源达到节省能源的目的， 相应的 eNB进入节能状态。
第二， 节能去激活： 开启被关闭的小区或恢复被限制的物理资源的使用， 来满足增长 的业务需求和业务盾量（Quality of Service, QoS )需求， 相应的 eNB小区从节能激活状态 恢复至正常状态。
节能的动作包含： 关闭 /打开小区、 关闭 /打开载波、 关闭 /打开收发机、 关闭 /打开家庭 基站（He B )、 以及其它。
节能补偿： 当某个网元进入节能状态后， 周围处于正常工作的网元就会进入节能补偿 激活状态， 通过扩大覆盖范围等方法补偿进入节能状态的小区的节能业务损失。
节能分为以下两个场景：
重叠覆盖 ( Overlapping )场景和非重叠覆盖 ( non-overlapping )场景。
Overlapping场景如图 1所示： 由基本覆盖小区 （ coverage cell, 即图中 cell A )和容量 增强小区 ( capacity-boosting cell或 hotspot, 即图中 cell C和 cell D ) 两部分组成。 容量增 强小区的覆盖完全与基本覆盖小区的覆盖重叠， 在网络负荷不大的时候， 容量增强小区可 以进行关闭， 以达到网络节能的目的。
Non-overlapping 场 景 如 图 2 。 演 进 通 用 陆 地 无 线 接 入 网 络 ( Evolved Universal Terrestrial Radio Access Network, E-UTRAN )小区 A~G相互邻接 , 没 有重叠覆盖， 即 E-UTRAN网络单层覆盖。 其中， 小区 Α具有覆盖补偿功能， 小区 B~G 具有节能功能。 在业务低峰时段（例如： 深夜）， 为了节省能源， 一些 E-UTRAN小区 B~G 关闭， 小区 A作为补偿节点扩大覆盖范围， 提供该地区业务的基本覆盖。
现有技术主要存在如下的缺点：对于 non-overlapping场景下，为了保证覆盖的连续性， 节能小区进入节能状态时， 需要补偿小区可以扩大覆盖范围， 以保证覆盖的连续性。 如果 在节能小区进入节能状态之后再扩大补偿小区的覆盖范围， 会导致短暂的覆盖漏洞； 而如 果在节能小区进入节能状态之前就扩大补偿小区的覆盖范围， 会导致补偿小区和节能小区 之间的千扰。 但是， 目前， 没有方法能够保证节能小区进入节能状态和补偿小区扩大覆盖 范围在同一时刻实现。
