Description

控制家 ^^站节能的方法、 系统、 家^ ^站和网元 技术领域 本发明涉及无线蜂窝通信领域， 具体而言， 涉及一种控制家庭基站节能的 方法、 系统、 家庭基站和网元。 背景技术
LTE( Long Term Evolution,长期演进）网络由 E-UTRAN( Evolved UTRAN, 演进 UTRAN ) 中的演进基站（ Evolved NodeB, eNB )和 EPC ( Evolved Packet Core, 演进分组交换中心） 组成， 网络扁平化。 其中， E-UTRAN包含和 EPC 通过 S 1接口连接的 eNB的集合， eNB之间能通过 X2连接， S 1、 X2是逻辑接 口。 一个 EPC可以管理一个或多个 eNB, —个 eNB也可以受控于多个 EPC, 一个 eNB可以管理一个或多个小区。 EPC由 MME( Mobility Management Entity, 移动管理单元） 和 SGW ( Serving Gateway, 月艮务网关）、 PGW ( Packet Data Network Gateway , 分组数据网络网关） 组成。 UMTS ( Universal Mobile Telecommunications System, 通用移动通讯系统）由 UTRAN ( UMTS Terrestrial Radio Access Network, UMTS陆地无线接入网） 和 CN ( Core Network, 核心 网） 组成， 其中 UTRAN是由 RNC ( Radio Network Controller, 无线网络控制 器） 和基站 NodeB组成的。 如图 1和图 2所示， 家庭基站用户通过家庭基站接入网（ Home ( e ) NodeB Access Network, H ( e ) NB AN ) 连接到核心网网络， 其中， H(e)NB AN由家 庭基站（ Home( e )NodeB , H( e )NB )和家庭基站网关（ Home (e)NodeB Gateway, H(e)NB GW ) 共同组成。 H(e)NB GW主要执行的功能为： 验证家庭基站的安 全性， 处理家庭基站的注册和接入控制， 负责交换核心网和家庭基站的数据。 H(e)MS ( Home (e)NodeB Management System, 家庭基站管理系统 ) 对家庭基 站进行运行、 维护和管理， 根据运营商要求配置和控制家庭基站， 最主要为 H(e)NB实现配置管理功能， 其中包括位置信息的核实、 为 H(e)NB进行参数配 置， 主要涉及到 CN级别的参数配置、 RAN ( Radio Access Network, 无线接入 网）侧的参数配置以及 RF ( Radio Frequency, 无线射频）的参数配置。 对于演 进的家庭基站（ HeNB ) 系统， HeNB可以不通过 HeNB GW而和 MME直接连 接。 随着家庭基站技术的发展， 引入了 CSG ( Close Subscriber Group , 封闭用 户组） 的 4既念， 用以对用户进行分组管理， 用户属于某一 CSG 的前提是其终 端设备使用 IMSI ( International Mobile Subscriber Identity, 国际移动用户标识 符）和该 CSG进行了签约。伴随着 CSG概念的引入，家庭基站引入了针对 CSG 接入模式的概念。 其中 CSG的家庭基站接入模式有三种： 分别是 Open (开放） 接入模式、 Close (封闭）接入模式和 Hybrid (混合）接入模式。 其中， 接入模 式为 Open的家庭基站， 允许签约和非签约用户接入， 这种接入模式的家庭基 站和正常的宏小区无异； 接入模式为 Close的家庭基站， 仅仅允许和该 CSG签 约的用户接入； 而对于接入模式为 Hybrid的家庭基站， 虽然同时允许签约和非 签约用户接入， 但是签约用户资源使用上优于非签约用户， 在资源紧张的情况 下， 家庭基站优先服务于签约用户， 有可能将非签约用户切换到别的小区或者 释放其信令连接。 其中判断 UE是以哪种身份接入网络的， 可以根据 UE的允 许接入 CSG列表（ Allowed CSG List )来完成。 允许接入 CSG列表是 UE签约 的所有的 CSG的信息列表， 分别存储于网络侧和 UE。 如果 UE接入的家庭基 站所属的 CSG(即 GSG标识）在 UE的允许接入 CSG列表中，则 UE是以 CSG 签约用户身份进入的， 否则 UE的接入是以非 CSG签约身份进入的。 家庭基站 HeNB通常包含于宏小区之中， 由于 HeNB的覆盖范围较小， 当 所支持的成员 UE离开了 HeNB所在的小区时， HeNB所在小区的负荷将艮低， HeNB是可以处于休眠状态的。 然而， 相关技术中的家庭基站无论在什么情况 下，

下文中将参考附图并结合实施例来详细说明本发明。 需要说明的是， 在不 冲突的情况下， 本申请中的实施例及实施例中的特征可以相互组合。 本发明实施例中的家庭基站所支持的成员 UE离开了该家庭基站所在的小 区时， 或者该家庭基站没有为成员 UE分配任何资源时， 该家庭基站可以考虑 关闭小区进入节能休眠状态， 为了不影响其他用户正常进入该小区， 该家庭基 站将节能休眠状态信息通知给关联网元 （例如， 邻居基站， 该家庭基站的家庭 网关或者核心网中的网元）。 基于此， 本发明实施例提供了一种控制家庭基站 节能的方法、 系统、 家庭基站和网元。 图 3示出了根据本发明实施例的一种控制家庭基站节能的方法流程图， 该 方法包括以下步 4聚： 步骤 S302: 家庭基站决定进入节能休眠状态； 家庭基站可以根据当前的资源分配情况判决是否进入节能休眠状态， 例如 家庭基站通过测量发现本小区当前负荷很低 （例如低于一个指定值）， 或者是 该家庭基站没有分配任何资源为 UE服务时， 判决可以进入节能休眠状态， 也 可以根据其他条件进行判决， 例如硬件消耗程度等。 步骤 S304: 该家庭基站向关联网元发送节能状态信息， 进入节能状态； 其 中， 节能状态信息包括： 该家庭基站所在小区的小区标识和该家庭基站的接入 模式； 其中， 家庭基站的接入模式有三种： 分别是 Open (开放）接入模式、 Close (封闭）接入模式和 Hybrid (混合）接入模式。 上述三种模式与基站对 UE的接入约束方式相关联， 例如： 开放接入模式 的家庭基站所在的小区可以称为开放（open ) 小区， 开放小区跟宏小区的特性 一样， 所有 UE都可以接入； 封闭接入模式的家庭基站所在的小区可以称为封 闭 （Close ) 小区， 封闭小区只有小区的成员 UE才能接入。 混合接入模式的家 庭基站所在的小区可以称为混合 （ Hybrid ) 小区， 混合小区允许签约用户 （指 与家庭基站所属的 GSG签约的用户）和非签约用户（指与家庭基站所属的 GSG 没有签约的用户）接入， 但是签约用户的优先级高于非签约用户的优先级， 即 是宏 UE和 CSG UE都可以接入， 但 CSG UE优先接入。 当家庭基站进入节能休眠状态， 并通知了邻区的 HeNB 或者 eNB, 由于 HeNB的接入模式有上述三种模式， 当该 HeNB为 Close (封闭）接入模式时， 并不是所有 UE都可以进入到处于节能休眠状态下的 HeNB所在小区。 当邻居 基站的小区负荷过重， 需要把部分 UE均衡到其他小区或者有 UE接近这个节 能休眠状态的 HeNB区域时， 如果 UE不是该 HeNB小区的成员 UE, 即使 4巴 这个 HeNB唤醒， 还是不能解决小区负荷过重的问题。 所以在这种情况下， 从 节能的角度考虑是不适合激活该 HeNB的。 因此， 本实施例的家庭基站在发送 节能状态信息时， 包括了该家庭基站的接入模式， 以及家庭基站的 CSG标识。 当家庭基站与关联网元之间有直接接口时， 家庭基站可以通过该直接接口 向关联网元发送携带有上述节能状态信息的消息。 当家庭基站与关联网元之间 没有直接接口相连， 而是通过移动管理单元相连时； 家庭基站可以通过移动管 理单元向关联网元发送携带有节能状态信息的消息。 其中， 携带有节能状态信息的消息可以被封装成数据信息包， 该数据信息 包以透传方式传输给关联网元。 上述携带有节能状态信息的消息可以为基站配置更新消息 （ eNB Configuration Update ) 或基站配置传输消息 ( eNB Configuration Transfer ), 或 者， 也可以自定义一个专用于发送上述节能状态信息的消息， 此时， 该节能状 态信息包括： 指示小区为关闭状态的标识信息， 用以表明此消息中指示的小区 的家庭基站处于节能休眠状态， 还包括该家庭基站所在小区的小区标识和该家 庭基站的接入模式。 步骤 S306: 该关联网元保存上述节能状态信息， 当确定有用户欲切换到该 家庭基站所在小区时， 居上述节能状态信息激活该家庭基站。 关联网元可以 居至少以下情况之一确定有用户欲切换到家庭基站所在 小区：
1 ) 关联网元接收到来自用户的接近指示， 接近指示包含有该家庭基站所 在小区的小区标识， 则确定该用户欲切换到该家庭基站所在小区；
2 ) 关联网元的负荷超过第一允许门限， 确定关联网元下的指定用户欲切 换到该家庭基站所在小区；
3 ) 关联网元获知管理区域中家庭基站的邻居基站负荷超过第二允许门限， 确定该邻居基站下的指定用户欲切换到该家庭基站所在小区。 关联网元确定有用户欲切换到家庭基站所在小区后， 则可以根据该家庭基 站发送的节能状态信息激活该家庭基站。 为了使关联网元能够根据实际情况进行激活操作， 当家庭基站的接入模式 为封闭接入模式或混合接入模式时， 家庭基站发送的上述节能状态信息中还包 括： 该家庭基站所属 GSG的 GSG标识； 关联网元根据节能状态信息激活该家 庭基站包括下述两种情况： 1 ) 关联网元确定该家庭基站的接入模式为开放接入模式， 则直接激活该 家庭基站；
2 ) 关联网元确定该家庭基站的接入模式为封闭接入模式或者混合接入模 式， 且才艮据用户接近该家庭基站和上述 GSG标识确定该欲切换到该家庭基站 所在小区的用户为上述家庭基站的签约用户， 再激活该家庭基站。 家庭基站的接入模式为混合接入模式时， 也可以不查看欲切换到家庭基站 所在小区的用户是否为该家庭基站的签约用户， 而是直接就激活该家庭基站。 该家庭基站进入节能休眠状态， 可以按照上述方法， 即由家庭基站自身决 定， 然后通知关联网元自己的节能状态信息。 或者， 家庭基站在决定进入节能休眠状态时，先向关联网元进行请求确认， 待收到确认消息后再通知邻区基站自己的节能状态信息， 然后进入节能休眠状 态。 基于此， 家庭基站向关联网元发送节能状态信息之前还可以包括： 家庭基 站向关联网元发送节能状态请求消息； 家庭基站收到关联网元回复的节能状态 确认消息后， 向关联网元发送节能状态信息。 其中， 关联网元可以为以下之一： 该家庭基站所在的宏基站、 该家庭基站的家庭网关或该家庭基站连接的核心网 中的网元。 根据实际使用需要， 上述节能状态信息可以包括小区的节能状态 （例如， 小区关闭或打开信息）， 小区标识， 小区的 CSG标识， 接入属性 （即上述接入 模式）。 本实施例的家庭基站在一定条件下决定进入节能休眠状态时， 先将节能状 态信息发送给关联网元， 关联网元再根据此节能状态信息在适当的时刻激活该 家庭基站， 解决了家庭基站耗电较大的问题， 利于节能环保。 并且该方式不会 影响用户正常切换到该家庭基站所在小区， 因此不影响用户体验。 实施例一 本实施例的家庭基站决定进入节能状态时， 将节能状态信息通知给邻居家 庭基站，本实施例以图 4所示的家庭基站分散布局在宏基站 eNB下的场景为例 进行说明， 家庭基站 HeNB A的接入属性为封闭接入模式，
