Description

一种节能小区的控制处理方法及基站 本申请要求在 2010 年 8 月 11 日提交中国专利局、 申请号为 201010251143.1、 发明名称为 "一种节能小区的控制处理方法及基站"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, 特别涉及一种节能小区的控制处理方法及基 站。 背景技术
目前, 移动通信网络的节能有以下几种途径:
1、 在保证覆盖、 容量、 服务质量不受影响的前提下, 优化站址的数量。
2、 寻找有效的提高能源利用率和降低设备功耗的方法。
3、 研究开发可持续能源 (风能、 太阳能等)。
RAN ( Radio Access Network, 无线接入网)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 e B (演进基站)都能够使用这种节能 策略, 那么就可以在不影响服务质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三种结构:
1、 分布式架构。 网元收集必要的信息进行自优化过程, 不需 OAM ( Operations and Maintenance, 运行和维护 ) 的参与。
2、 集中式架构。 OAM从网元收集信息触发节能算法, 然后决定网元的 后续动作。 3、 混合式结构。 以上两种方法混合使用。
ESM方案: ESM ( Energy Savings Management, 节能管理)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。
节能的方案包含两个基本过程:
1、节能激活: 通过关闭 eNB的小区或限制使用部分物力资源达到节省能 源的目的, 相应的 eNB进入节能状态。
2、 节能去激活: 开启被关闭的小区或恢复被限制的物力资源的使用, 来 满足增长的业务需求和 Qos ( Quality of Service,服务质量)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 eNB;
#其它。
