Description

一种在网元间实现节能控制的方法及装置 本申请要求在 2010年 05月 12日 提交中 国专利局、 申请号为 201010175330.6、发明名称为 "一种在网元间实现节能控制的方法及装置,,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
本发明涉及通信技术领域, 特别是指一种在网元间实现节能控制的方法 及装置。 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他们考虑的因素。 在长期演进系统 ( Long Term Evolution , LTE )、 通用移动通信系统 ( Universal Mobile Telecommunication System, UMTS )、 全求移动通讯系统 ( Global System for Mobile communication, GSM )共存的复杂网络中, 节能是一个非常重要的议 题。
目前, 移动通信网络的节能有以下几种途径: 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; 寻找有效的提高能源利用率和降 低设备功耗的方法; 研究开发可持续能源, 例如风能、 太阳能等。
在节能过程中,网管系统( Operation, Administration, Maintenance, OAM ) 扮演着核心角色, 它可以通过集中式控制直接对节能进行干预, 也可以通过 分布式间接的提供节能所需要的信息。
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, 如果所有的演进型基站 (evolved Node B, eNB )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。 对于自由化网络而言, 节能实体大致可分为三种结构:
分布式架构: 网元收集必要的信息进行自优化过程, 不需 OAM的参与; 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;
混合式结构: 以上两种方法混合使用。
目前只有在 LTE系统中有相应的节能方案和流程,而且 LTE系统中只有 X2 接口支持这一过程, 对于运营商没有部署 X2的场景, 以及异系统间重复覆盖 的场景也无法实现节能功能。 发明内容
本发明提供一种在网元间实现节能控制的方法及装置, 可以在不同网元 间实现节能控制。
本发明实施例提供的一种在网元间实现节能控制的方法, 包括: 第一节点设备根据 OAM提供的节能策略信息,确定自身管辖的第一小区 需要进入或离开节能状态, 并确定第二小区需要进入或离开节能补偿激活状 态, 且第二小区为第一小区的邻小区;
第一节点设备进入或离开节能状态, 并向第二小区发送进入或离开节能 状态指示信息, 所述进入或离开节能状态指示信息用于提供给第二小区与 OAM协商进入或离开激活节能补偿状态。
本发明实施例提供的一种在网元间实现节能控制的方法, 包括:
OAM确定在网络中的设定区域实施 ESM过程, 并向该区域的节点设备 提供 ESM策略信息, 所述 ESM策略信息用于提供给该节点设备确定其管辖 的第一小区是否进入节能状态;
OAM与第二小区协商并通知第二小区进入节能补偿状态, 第二小区为第 一小区的邻小区。

才艮据所述离开节能状态指示信息与 OAM协商离开激活节能补偿状态。 在具体实现过程中, 可以按照图 1、 2和 3所示的实施例进行交互, 这里 不再赘述。
下面举具体实施例详细说明本发明的技术方案。 节能管理(ESM ) 方案包含两个基本过程, 即节能激活和节能去激活。 如果针对 eNB和 HeNB, 技能激活过程是指通过关闭 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。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需求, 相应的 eNB小区从节能激活状态恢复至正常状态。
OAM根据用户数据进行业务量测量, 来决定是否在网元中进行相应的节 能过程。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 HeNB或者其它动作。
当某个网元进入 ESM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 ESM小区的节能业务损失。
以下实施例中, 提供了一种未来异系统网络中利用网元进行节能的方案, 尤其是对于存在重复覆盖的异系统之间的小区节能方法。 对于分布式架构, 0&M决定在网络中的某个区域实施 ESM过程, 同时向该区域的网元(eNB ) 提供相应的 ESM策略和规定, 网元根据自己的算法选择进行节能的小区, 让 其进入节能状态。 同时根据该小区的 topo结构通知该小区的邻区进行节能补 偿状态, 节能补偿状态的邻区通过调整自身发射功率等方法扩大本小区的覆 盖范围, 来补偿节能小区的覆盖漏洞和业务需求。
实施例一、 Intra-RAT场景 ( Sl/Iur/Iub )。
对于此方案, 适用于同系统内部的 inter-eNB之间, inter-NodeB之间, 以 及 inter-BSC之间的节能。 参见图 4所示, 具体过程如下:
步骤 401 : eNBl根据 OAM提供的相关节能策略进行判决, 决定让 eNB 1 下的某个小区进入节能状态,同时让该小区的邻小区即 eNB2下的某个小区进 入节能激活补偿状态;
步骤 402a〜步骤 402b: eNBl向邻区发送进入节能状态指示, MME透传 该消息给目标小区;
步骤 403: 目标小区与 OAM协商后激活节能补偿功能, 开始调整自己的 发射功率等参数,扩大业务覆盖范围,弥补由 eNBl小区节能造成的覆盖不足; 步骤 404:当 eNBl中的节能状态下的小区满足了离开节能状态的条件后, 恢复正常状态, 同时离开节能激活状态;
步骤 405a〜步骤 405b: eNBl向邻区发送离开节能状态指示消息,由 MME 透传给目标小区;
步骤 406: 目标小区离开节能补偿状态, 恢复原来的配置。
实施例二、 Inter-RAT(Iur-g或核心网透传), 如图 5所示, 具体过程如下: 步骤 501 : RNC根据 OAM提供的相关节能策略进行判决, 决定让 RNC 下的某个小区进入节能状态, 同时让该小区的邻小区即 BSC下的某个小区进 入节能激活补偿状态;
步骤 502: RNC向邻区发送进入节能状态指示, 并经由 Iur-g接口传送给 目标小区;
步骤 503: 目标小区与 OAM协商后激活节能补偿功能, 开始调整自己的 发射功率等参数,扩大业务覆盖范围,弥补由 RNC小区节能造成的覆盖不足; 步骤 504:当 RNC中的节能状态下的小区满足了离开节能状态的条件后, 恢复正常状态, 同时离开节能激活状态;
步骤 505: RNC向邻区发送离开节能状态指示消息, 并经由 Iur-g接口 传送给目标小区;
步骤 506: 目标小区离开节能补偿状态, 恢复原来的配置。
其中, 节能状态的改变可以根据小区的负载信息进行, 也可以根据业务 高峰时段的划分进行。 进入节能状态指示中包含但不限于: 目标小区标识、 节能状态或节能补偿状态的起始时间信息以及节能指令。
其中, 目标小区标识为 E-CGI、 PCI/PSC或 CSG ID等。 节能指令可以包 括: 打开或关闭小区, 降低发射机发射功率, 关闭载波载扇等。
上述实施例以 Iur-g接口为例提供了利用系统间直接接口进行节能的方 法,此外还可以通过 S1接口或 Iu接口与核心网进行控制信令的交互, 完成异 系统同覆盖场景下的节能功能, 参见实施例三。
实施例三: LTE系统与 UMTS系统间的节能 参见图 6和图 7所示, 对于宏基站而言, 多数业务都是集中在某些高峰 时段进行的, 在一些特殊时间段比如凌晨 1点到 5点, 业务量的需求是很小 的, 此时如果仍然按照正常的发射功率工作, 显然浪费了很多资源; 同理, 在任何时间段, 宏基站都可以对该基站下某小区的业务量进行监控, 如果在 某段时间内, 业务量持续低于设定的阔值, 就可以关闭部分小区或载扇, 同 时通过拓朴结构牺牲某个小区的容量, 扩大其覆盖范围, 这样既能够满足业 务的需求, 又能达到节能的目的。
其中, 图 6中所示的 No-ES, 表示非节能状态, 图 7中所示的 ESaving, 表示节能状态。
在特定的时间段或满足某种条件后, 外围的 6个小区 (UMTS小区)都 满足了进入节能状态的条件, 进入节能状态, 中央的小区 (LTE 系统小区) 进入节能补偿状态, 以牺牲容量的方式换取更大的覆盖范围, 弥补周围小区 关闭带来的覆盖漏洞, 这样既能满足节能的需求, 又能够保证业务的正常性。 一旦某个小区检测到数据业务大幅上升, 就可以离开节能状态, 恢复正常功 能。 如果中央小区与周围的小区属于相同 eNB, 那么可以在 eNB内实现, 如 果属于不同的 eNB , 则可以通过上述实施例一实现。 对于 LTE系统和 UMTS 系统来说, 目前两种系统间没有直接的接口, 因此可以通过 S1接口、 Iu接口、 Iub接口共同实现对节能的控制和实现, 参见图 8所示。
实施例四: UMTS系统与 GSM系统间的节能
如上述方案实施例二所示, UMTS系统中 RNC下的某个小区与 GSM系 统中 BSC下的某个小区属于重复覆盖的场景, 此时基于 OAM的判决, 决定 让 BSC下的某个小区进入节能状态,可以通过 Iur-g接口发送相应的节能信令 和参数, 包含的参数和内容如上所述。
实施例五、 UMTS系统内部节能实现
对于 UMTS系统内部的小区之间 , 可以通过所属 RNC之间的 Iur接口进 行节能的控制和相应流程, 如图 9所示, 具体如下:
步骤 801 : RNC1根据 OAM提供的相关节能策略进行判决,决定让 RNC1 下的某个小区进入节能状态, 同时让该小区的邻小区即 RNC2下的某个小区 进入节能激活补偿状态;
步骤 802: RNC1向邻小区发送进入节能状态指示, 并经由 Iur接口传送 给目标小区;
步骤 803: 目标小区与 OAM协商后激活节能补偿功能, 开始调整自己的 发射功率等参数, 扩大业务覆盖范围, 弥补由 RNC1 小区节能造成的覆盖不 足;
步骤 804: 当 RNC1 中的节能状态下的小区满足了离开节能状态的条件 后, 恢复正常状态, 同时离开节能激活状态;
步骤 805: RNC1向 RNC2发送离开节能状态指示消息, 并经由 Iur接口 传送给目标小区;
步骤 806: 目标小区离开节能补偿状态, 恢复原来的配置。
