Description

向封闭用户组小区切换的处理方法 ^置 技术领域 本发明涉及通信领域, 具体而言, 涉及一种向封闭用户组 ( Close Subscriber Group, 简称为 CSG ) 小区切换的处理方法及装置。 背景技术 随着无线通信技术的发展,逐渐出现了家庭基站。家庭基站是一种小型、 低功率的基站, 部署在家庭及办公室等室内场所, 主要作用是为了给用户提 供更高的业务速率并降低使用高速率服务所需要的费用, 同时弥补已有分布 式蜂窝无线通信系统覆盖的不足。 家庭基站的优点是实惠、 便捷、 低功率输 出、 即插即用等。 图 1 是根据相关技术的家庭基站 (Home (evolved) NodeB , 简称为 H(e)NB ) 网络结构的示意图, 如图 1所示, 家庭基站用户是通过家庭基站接 入网 ( Home (e)NodeB Access Network, 简称为 H(e)NB AN ) 连接到核心网 的, 其中, H(e)NB AN由 H(e)NB和家庭基站网关 ( Home (e)NodeB Gateway, 简称为 H(e)NB GW ) 共同组成。 H(e)NB GW主要执行的功能为: -险证家庭 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。 家庭基站管理系统( Home (e)NodeB Management System, 简称为 H(e)MS )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, 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, 主要涉及到核心网 ( Core Network, 简称为 CN ) 级 别的参数配置、 无线接入网 ( Radio Access Network, 简称为 RAN ) 侧的参 数配置以及射频 (Radio Freqency, 简称为 RF ) 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而和移动管理实体( Mobile Management Entity, 简称为 MME ) 直接连接, HeNB通过 S 1-MME或 S 1-U 和演进的分组核心网 (Evolved Packet Core, 简称为 EPC ) 进行通信, 中间 网元也可以包括安全网关 ( Security Gateway,简称为 SeGW )„ 图 2是根据相关技术的 HNB网络结构的示意图, 如图 2所示, 终端通 过 Uu接口接入 3G HNB , 3G HNB经由互联网协议 ( Internet Protocol , 简称 为 IP ) 网络 ( network ) 和 SeGW通过 TR-069与 HMS进行通信, 3G HNB 经由 IP网络和 SeGW通过 Iuh接口与 HNB GW进行通信, HNB GW通过 Iu 接口与 CN进行通信。 随着家庭基站技术的发展, 引入了 CSG, 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的国际移动用户识别号 (International Mobile Subscriber Identification Number,简称为 IMSI )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,分别是开放( Open )接入模式、闭合( Close ) 接入模式和混合 ( Hybrid )接入模式。 具体地, 接入模式为 Open 的家庭基 站, 允许签约和非签约用户接入, 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, 判断用户 设备 (User Equipment, 简称为 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。 Allowed CSG list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在 UE的 Allowed CSG List,则 UE是以 CSG签约成 员身份进入的, 否则 UE的接入是以非 CSG签约成员身份进入的。 家庭基站作为无线侧基站设备, 必然支持切换的功能。 向 CSG小区或 者 Hybrid小区的切换称之为进入 ( Inbound ) 切换。 图 3是根据相关技术的 LTE系统下向 Hybrid小区的切换的流程图, 如图 3所示, 在长期演进( Long Term Evolution, 简称为 LTE ) 系统下, 向 Hybrid小区的 Inbound切换流程 包括如下的步骤: 步骤 301 , 源无线接入网 ( Radio Access Network, 简称为 RAN ) 决定 发起向目标 Hybrid小区的切换, 向 MME发送切换要求消息。 在切换要求消 息中携带目标小区的封闭用户组标识 ( Close Subscriber Group Identity , 简称 为 CSG ID ), 并且指明目标小区的接入模式为 Hybrid。 步骤 302, MME在收到切换要求后,根据消息中的 CSG ID对 UE进行 接入身份的判断。 其判断过程是: 如果目标小区的 CSG ID在 UE的 Allowed CSG List里面, 即, UE和该 CSG进行了签约, 则认为该 UE是以 CSG成员 身份接入的, 否则以非成员身份接入。 步骤 303至步骤 304, MME进行完 UE的身份判断以后, 向目标基站 发送切换请求消息,该消息里面除了携带和正常切换请求消息一样的参数外, 还携带源 RAN提供的 CSG ID , 以及 MME判断后的 UE的接入身份信息。 如果目标基站通过家庭基站网关和 MME连接, 则切换请求消息首先到达目 标家庭基站网关, 目标家庭基站网关然后将切换请求消息传递到目标基站, 否则 MME直接将该切换请求消息发往目标基站。 另外, 目标家庭基站网关 也可以认证 CSG ID的有效性, 判断切换失败, 向 MME发送切换失败。 步骤 305 , 目标基站收到切换请求消息以后, 验证 CSG ID , 即, 判断 该消息里面的 CSG ID是否是自己小区真实的 CSG ID,如果是则进行到步骤 306, 否则切换失败, 向 MME发送切换失败消息。 步骤 306, 目标基站向家庭基站网关返回切换请求响应。 步骤 307, 家庭基站网关向 MME返回切换请求响应。 步骤 308, MME向源 RAN发送切换命令。 对于通用移动通信系统 ( Universal Mobile Telecommunications System, 简称为 UMTS ), 其切换流程和上面类似, 在切换过程中使用的消息名称不 同, 图 4是根据相关技术的 UMTS下向 Hybrid小区的切换的流程图, 如图 4 所示, 包括如下的步骤: 步骤 401 , 源 RAN决定发起向目标 Hybrid小区的重定位, 向 CN发送 重定位要求消息, 在重定位要求消息中携带目标小区的 CSG标识 (ID ), 并 且指明目标小区的接入模式为 Hybrid。 步骤 402, CN在收到重定位要求后,根据消息中的 CSG ID对 UE进行 接入身份的判断。 其判断过程是: 如果目标小区的 CSG ID在 UE的 Allowed CSG List里面, 即, UE和该 CSG进行了签约, 则认为该 UE是以 CSG成员 身份接入的, 否则以非成员身份接入。 步骤 403至步骤 404 , CN进行完 UE的身份判断以后, 向目标无线网 络控制器 ( Radio Network Controller, 简称为 RNC )发送重定位请求消息, 该消息里面除了携带和正常重定位请求消息一样的参数外, 还携带源 RAN 提供的 CSG ID, 以及 CN判断后的 UE的接入身份信息。 如果目标 RNC通 过家庭基站网关和 CN连接,则重定位请求消息首先到达目标家庭基站网关, 目标家庭基站网关然后将重定位请求消息传递到目标 RNC, 否则 CN直接将 该重定位请求消息发往目标 RNC。 另外, 目标家庭基站网关也可以认证 CSG ID的有效性, 判断切换失败, 向 CN发送重定位失败。 步骤 405 , 目标 RNC收到重定位请求消息以后, -险证 CSG ID, 即, 判 断该消息里面的 CSG ID是否是自己小区真实的 CSG ID,如果是则进行到步 骤 406, 否则重定位失败, 向 CN发送重定位失败。 步骤 406 , 目标 RNC向家庭基站网关返回重定位请求响应。 步骤 407, 家庭基站网关向 CN返回重定位请求响应。 步骤 408, CN向源 RAN返回重定位命令。 针对以上流程, 由于目标小区的接入模式是 Hybrid的, 其本来是可以 接受签约用户和非签约用户的接入的, 仅仅只在接入以后的资源使用上签约 用户优先于非签约用户。 但是, 上述流程中, 在目标网元对 CSG -险证不通过 的情况下, 则认为切换失败, 所以降低了切换的效率。 发明内容 本发明的主要目的在于提供一种向 CSG小区切换的处理方法及装置, 以至少解决上述问题。 才艮据本发明的一个方面, 提供了一种向封闭用户组小区切换的处理方 法, 包括: 目标网元接收切换消息; 目标网元对切换消息中携带的封闭用户 组标识 CSG ID进行-险证, 如果-险证不通过, 则向目标网元的上级网元返回 带有目标网元的 CSG ID的响应消息。 优选地, 当目标网元的接入模式为混合 Hybrid时, 如果-险证不通过, 上述方法还包括: 目标网元允许切换消息对应的用户设备以非成员身份接入 或以成员身份接入。 优选地, 当目标网元的接入模式为混合 Hybrid时, 如果-险证不通过, 上述方法还包括: 目标网元将目标网元默认的接入身份信息向上级网元传递。
