家庭基站是基站 (NodeB)或者演进基站（ eNodeB)的一种，即是一种小型、 低功率的基站， 作为私人用户的专属资源被部署在家庭、 团体、 公司或者是 学校等私人场所使用。 家庭基站的主要作用是给用户提供更高的业务速率、 降低使用高速率服务所需要的费用， 以及弥补已有分布式蜂窝无线通信*** 覆盖的不足。 家庭基站的优点包括： 实惠、 便捷、 低功率输出、 以及即插即 用。 家庭基站用户是通过家庭基站接入网（ Home NodeB Access Network, 简 称 HNB AN )连接到核心网网络的， HNB AN由家庭基站（ Home NodeB , 简称 HNB )和家庭基站网关 （ Home NodeB Gateway, 简称 HNB GW )共同 组成。 家庭基站网关主要执行的功能包括： 验证家庭基站的安全性， 处理家 庭基站的注册和接入控制， 对家庭基站进行运行维护管理， 根据运营商要求 配置和控制家庭基站， 负责交换核心网和家庭基站的数据。 在通用移动通信*** ( Universal Mobile Telecommunication System, 简称
UMTS ) 中， 家庭基站必须通过家庭基站网关接入到核心网中， 其中家庭基 站和家庭基站网关之间的接口为 Iuh接口， 而家庭基站网关到核心网之间的 接口为 Iu接口。 在长期演进（ Long Term Evolution, 简称 LTE ) ***中， 演进型家庭基 站 （HeNB ) 可以不通过家庭基站网关直接连接到核心网。 如果家庭基站网 关存在， 家庭基站和家庭基站网关， 家庭基站网关和核心网之间的接口均为 S1接口。 S1接口的协议栈分为控制面和用户面。
LTE和 UMTS***中家庭基站都基于 TR-069协议栈接入家庭基站管理 ***（ H(e)NB Management System , 简称 HMS ) , 并由后者负责家庭基站的 管理及配置。 家庭基站覆盖的多个小区组成家庭基站覆盖区域。 家庭基站的接入模式 包括三种： 封闭接入模式、 混合接入模式和开放接入模式。 封闭接入模式的 家庭基站只允许经过授权的用户接入， 如家庭成员、 以及团体成员等用户。 混合接入模式的家庭基站允许所有的用户接入， 但对于该家庭基站的授权用 户享有优先或优惠的条件。 开放接入模式的家庭基站允许所有的用户接入。 对于封闭成员组（Closed Subscriber Group, 简称 CSG )小区， 不仅有一 个全局的小区标识（ Cell Global Identifier, 简称 CGI ) , 还有 CSG小区标 识 (CSG ID)。拥有不同全局的小区标识的 CSG小区可以对应同一个 CSG ID。 连接家庭基站的家庭基站网关或核心网网元可以在家庭基站的初始化阶段获 得家庭基站的 CSG标识、 接入模式以及家庭基站所建小区的全局小区标识。 非家庭基站一般称为基站或宏基站， 所属小区称为宏小区。 随着技术讨论的 不断推进， CSG概念不仅仅应用于家庭基站，对于宏基站同样可以应用 CSG 的方式对用户进行接入控制。 为了实现上述三种不同接入模式要求的接入控制， 标准组织引入了 CSG 的概念。通过用户加入特定 CSG, 以及为家庭基站所建小区赋予逻辑的 CSG 属性（包括 CSG小区标识）， 核心网和家庭基站及家庭基站网关共同完成对 接入用户的控制。 当用户设备 ( User Equipment , 简称 UE )希望驻留在封 闭或混合模式的 CSG小区时， 家庭基站将小区所属的 CSG标识以及接入模 式上报给网络侧， 由网络侧根据 UE的通信上下文及签约数据检查 UE是否 为该 CSG的成员。 对于封闭模式的 CSG小区， 只允许授权用户 （UE成为 CSG组成员便成为授权用户）接入， 非授权用户禁止接入； 对于混合模式的 CSG小区， 网络侧会允许所申请用户接入， 但同时将用户是否为该 CSG成 员的信息通知家庭基站。 而家庭基站会对成员用户进行优先或优惠的接纳管 理。开放模式的家庭基站表现和普通的宏基站一样，可以不作基于 CSG的接 入控制， 直接接入。
UE 进入一个小区有两种途径， 一种是直接接入目标小区， 另一种是通 过切换方式由其它小区切入目标小区。 UE 的切换流程可以通过无线网络控 制器（ Radio Network Controller, RNC ) /基站与核心网之间的接口信令交互， 也可以通过 RNC之间或基站之间的直接接***互。 但是， UE通过源接入网 元和目标接入网元之间的直接接口进行切换时， 现有技术中没有执行接入控 制的实施方式。

本发明为终端通过直接接口进行切换时接入控制过程提供可实施方案。
附图概述 图 1是实施例中在终端切换过程中对终端进行接入控制的方法流程图。
本发明的较佳实施方式
下文中将结合附图对本发明的实施例进行详细说明。 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任意组合。 本实施例提供了一种在终端切换过程中对终端进行接入控制的***， 该 ***包括终端所属源接入网元， 终端待切入的目标接入网元。 源接入网元设置为： 通过直接接口将源小区的封闭成员组配置信息通知 至目标接入网元。 目标接入网元设置为： 根据目标小区的封闭成员组配置信息和源小区的 封闭成员组配置信息判断是否将终端接入至目标小区。 源接入网元将源小区的封闭成员组配置信息通知至目标接入网元的方式 可以是以下方式中的一种： 源接入网元在所述源接入网元和所述目标接入网元建立直接接口之前， 通过操作维护管理网元的静态配置信息与目标接入网元进行封闭成员组配置 信息交互； 源接入网元在所述源接入网元和所述目标接入网元获知对方的直接接口 信息过程中， 通过直接接口传输地址发现流程与目标接入网元进行封闭成员 组配置信息的交互； 源接入网元通过直接接口建立流程将源小区的封闭成员组配置信息发送 至目标接入网元； 源接入网元通过基站配置更新流程将源小区的封闭成员组配置信息更新 至目标接入网元。 在 LTE***中，源接入网元和目标接入网元指宏基站或家庭基站或具有 基站功能的接入节点； 在 UMTS***中， 源接入网元和目标接入网元指无线 网络控制器或宏基站或家庭基站或具有基站功能的接入节点 （例如中继节 点 )。如果接入网元是家庭基站则可选通过家庭基站网关（ HeNB GW或 HNB GW )接入核心网； 如果接入网元是中继节点， 则需要通过宿主基站（DeNB ) 接入核心网。 不同接入网元有相应的后台管理***（OAM或 HMS ) 。
如图 1所示， 在终端切换过程中对终端进行接入控制的方法包括： 步骤 101 , 源接入网元通过直接接口将源小区的封闭成员组配置信息通 知至目标接入网元。 其中，封闭成员组配置信息包括封闭成员组标识和封闭成员组接入模式。 源接入网元将源小区的封闭成员组配置信息通知至目标接入网元的方式 可以是以下方式中的一种： 一 , 源接入网元和目标接入网元建立直接接口之前 , 源接入网元和目标 接入网元通过操作维护管理网元的静态配置信息获知对方小区的封闭成员组 配置信息。 具体的， 接入网元初始上电后， 从后台的操作维护管理网元的静态配置 信息获知基站所需配置参数，其中包括小区所配置的 CSG信息。此接入网元 进入运行状态， 按照配置参数建立小区 X, 在空口广播小区参数， 其中包括 所配置的 CSG信息。接入网元从操作维护管理网元的静态配置信息中获知需 要与对方建立直接接口， 静态配置信息中还包括承载该直接接口对端的传输 层连接地址及端口信息， 还可以包括对端的 CSG信息。 二， 源接入网元和目标接入网元在获知对方的直接接口信息过程中， 通 过直接接口传输地址发现流程 (例如， 此流程被包含在 LTE***的演进基站 配置流程（ eNB Configuration Transfer )或 MME配置流程（ MME Configuration Transfer ) 中 )进行封闭成员组配置信息的交互。 具体的， 源接入网元通过核心网向目标接入网元发送直接接口信息请求 ( e.g. eNB/MME Configuration Transfer ) , 该请求中携带源接入网元用于该 直接接口的传输层地址及端口信息，还可以包括源小区的 CSG信息。 目标接 入网元响应该请求（ e.g. eNB/MME Configuration Transfer ) , 该响应中携带 目标接入网元用于该直接接口的传输层地址及端口信息， 还可以包括目标小 区的 CSG信息。 源接入网元和目标接入网元建立直接接口之前需要获知对端的 CSG 配 置信息从而判断是否需要建立直接接口， 通过上述方式一和方式二中的交互 过程可完成通知封闭成员组配置信息的操作。 源接入网元和目标接入网元在 源小区和目标小区的 CSG 配置信息相同时或者对端的小区为开放接入模式 小区或普通宏小区时判定需要建立直接接口。 三， 源接入网元通过直接接口建立流程（例如 LTE ***中 Χ2 Setup
Request和 X2 Setup Response组成的 X2接口建立流程 )将源小区的封闭成 员组配置信息发送至目标接入网元（一般是在方式一和方式二所示的流程中 未进行 CSG配置信息交互的情况下） 。 四， 源接入网元通过基站配置更新流程将源小区的封闭成员组配置信息 更新至目标接入网元。 具体的， 源接入网元和目标接入网元建立起直接接口后， 在两者之前还 未交互封闭成员组配置信息的情况下或者封闭成员组配置信息发生变化的情 况下， 源接入网元通过基站配置更新流程 (例如 LTE***中演进基站配置更 新流程 ( eNB Configuration Update ) )将源小区的封闭成员组配置信息通知 至目标接入网元。 综上所述， 两个接入节点之间可以在直接接口参数配置（静态 /动态）阶 段、直接接口建立阶段或直接接口维护更新阶段交互双方的 CSG配置。如果 双方的直接接口是通过某代理节点（e.g.家庭基站网关或宿主基站）进行了代 理， 则可由代理节点在上述流程中分别以被代理节点的身份响应流程， 并向 A或者 B通知对端的 CSG配置。 另外， 源接入网元和目标接入网元建立起直接接口后， 源接入网元判断 需要将 UE切换至目标接入网元时， 向目标接入网元发起直接接口切换流程 (例如 LTE***中 X2接口切换流程 ( X2 Handover ) ) , 并且在源小区的接 入模式为混合接入模式， 源接入网元向目标接入网元发起切换请求时， 源接 入网元通过此直接接口切换流程将终端是否是源小区封闭成员组成员的信息 通知至目标接入网元。 步骤 102, 目标接入网元根据目标小区的封闭成员组配置信息和源小区 的封闭成员组配置信息判断是否将终端接入至目标小区。 目标小区的接入模式为封闭接入模式时， 目标接入网元在以下情况下允 许终端接入： 源小区是与目标小区具有相同封闭成员组小区标识的封闭接入模式封闭 成员组小区； 或者， 源小区是与目标小区具有相同封闭成员组小区标识的混 合接入模式封闭成员组小区并且终端是源小区中的封闭成员组成员。 目标小区为混合接入模式封闭成员组小区时， 目标接入网元允许终端接 入， 并根据以下条件决定终端在目标小区的成员身份： 源小区是与目标小区具有相同封闭成员组标识的封闭接入模式封闭成员 组小区， 目标接入网元以封闭成员组成员身份接入终端； 源小区是与目标小区具有相同封闭成员组标识的混合封闭成员组小区， 终端在目标小区中的成员身份与在源小区中相同； 源小区是开放接入模式小区或普通宏小区或具有其他封闭成员组标识的 封闭接入模式封闭成员组小区或混合接入模式封闭成员组小区， 以非封闭成 员组成员身份接入终端。 目标小区为开放接入模式小区或普通宏小区， 允许终端接入。 此方法中， UE 成功接入至目标接入网元后， 目标接入网元向核心网发 送 UE上下文必要的更新， 如用户面地址及 UE新的 CSG信息（所接入小区 的 CSG标识以及接入模式以及 UE是否具有此目标小区的 CSG成员身份）。 本发明为终端通过直接接口进行切换时接入控制过程提供可实施方案， 并且提供了一种通过直接接口切换流程进入封闭接入模式或混合接入模式的 CSG小区的方法， 该方法支持签约 UE接入封闭 CSG小区， 并在接入混合 CSG小区时能够让目标基站准确的判断所接入 UE的成员身份。

当然， 本发明还可有其他多种实施例， 在不背离本发明精神及其实质的 但这些相应的改变和变形都应属于本发明所附的权利要求的保护范围。 本领域普通技术人员可以理解上述方法中的全部或部分步骤可通过程序 来指令相关硬件完成， 所述程序可以存储于计算机可读存储介质中， 如只读 存储器、 磁盘或光盘等。 可选地， 上述实施例的全部或部分步骤也可以使用 一个或多个集成电路来实现。 相应地， 上述实施例中的各模块 /单元可以釆用 硬件的形式实现， 也可以釆用软件功能模块的形式实现。 本发明不限制于任 何特定形式的硬件和软件的结合。
