Description

种切换的触发方法、 系统和装置 本申请要求于 2008年 6月 16日提交中国专利局、 申请号为 200810110928.X、 发明名 称为 "一种切换的触发方法、 系统和装置" 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
本发明实施例涉及通信技术领域， 特别涉及一种切换的触发方法、 系统和装置。 背景技术
家用基站， 是 3G ( 3rd Generation, 第三代移动通信技术）领域的前沿技术和热门话题。 3G家用基站可以与运营商的原有网络设备无缝连接， 充分利用用户已有的宽带接入资源， 最终为用户提供 FMC ( Fixed-Mobile Convergence, 移动和固网融合） 业务。 通过 3G家用 基站， 大量的移动业务可以被室内家用基站所吸收， 大大降低了运营商宏蜂窝的数量， 为 运营商节约了大量的设备投资费用和维护费用， 是最为经济的室内信号覆盖技术。
现在， 用户需求随着移动通信技术的发展越来越多样化， 为了适应多样化的用户需求 系统设备也出现多样化， 备受关注的家庭室内覆盖和企业级的内部覆盖基站以及其他一些 受限网络应运而生。 这种网络可以是家用基站， 家庭小区 （Home Cell ) , 接入点 （Access Point) , 私有网络 （Private Network) , 私有小区 （Private Cell ) 等， 还有某些特定频率层的 受限网络。 最近 3GPP ( 3rd Generation Partnership Project, 第三代移动通信技术合作伙伴计 划） 又引入了 CSG ( Closed Subscriber Group, 封闭用户组） 的概念， 如果用户签约到 CSG 内或者被 CSG的主人添加到 CSG内， 则该用户被允许在 CSG小区内正常驻留以及申请业 务； 而没有签约及没有被 CSG主人添加到 CSG内的用户无法正常驻留到 CSG小区， 也无 法发起业务。
在 3G网络中， 由于 UE (User Equipment, 用户设备） 不知道可以访问哪些私有小区， 所以现有技术对私有小区的接入限制是通过网络拒绝方式实现的。即不管 UE有没有接入权 限， UE都可以向网络侧发起位置区更新请求， 由网络侧来甄别用户是否具有权限。 对于有 权限的用户， 网络侧允许其接入， 对于无权限的用户， 网络侧拒绝其接入。
为了限制无权限用户发起的无效接入， 和网络拒绝方式一起， 现有技术还引入了白名 单的概念， 就是说， 把 UE允许接入的小区列为白名单， 并保存在 UE的用户卡中。 但是当 用户第一次接入网络， 或者 UE的白名单的配置和网络侧不同时， 没有权限的用户也会向网 络发起接入。
在 UE进行小区切换时， 现有技术是通过源无线网络控制器根据邻区列表， 并根据 UE 上报的测量报告的事件进行切换判决的， 即根据 UE测量到的下行信号的质量进行切换判 决。
但是，现有标准规定，无线网络控制器向 UE下发的邻区信息中所包含邻小区的个数不 能超过 32*3， 即每种类型 （同频、 异频或异系统） 邻小区的个数最大为 32， 因此当一种类 型的家用基站小区的数量很大， 超过 32时， 部分家用基站小区无法通过空口向 UE下发测 量控制消息， 因此无法触发不具备自搜索能力的 UE进行小区测量， 从而无法使不具备自搜 索能力的 UE进行从宏小区向家用基站小区的切换。 发明内容
本发明实施例提供一种切换的触发方法、系统和装置， 以使不具备自搜索能力的 UE能 够进行从宏小区向家用基站小区的切换。
为达到上述目的，本发明实施例一方面提供一种切换的触发方法，包括：家用基站 HNB 接收相邻宏小区无线网络控制设备发送的用户设备 UE的上行物理信息，所述 UE为所述家 用基站的签约 UE; 根据所述 UE的上行物理信息搜索对应的 UE; 如果搜索到所述对应的 UE, 向所述宏小区无线网络控制设备发送切换指示消息。
另一方面， 本发明实施例还提供一种切换的触发系统， 包括： 无线网络控制设备， 用 于发送用户设备 UE的上行物理信息； 和家用基站，用于接收相邻宏小区无线网络控制设备 发送的 UE的上行物理信息， 根据所述 UE的上行物理信息搜索对应的 UE， 在搜索到所述 对应的 UE之后， 向所述宏小区无线网络控制设备发送切换指示消息， 所述 UE为所述家用 基站的签约 UE。
再一方面， 本发明实施例还提供一种家用基站， 包括： 接收模块， 用于接收相邻宏小 区无线网络控制设备发送的用户设备 UE的上行物理信息，所述 UE为所述家用基站的签约 UE; 搜索模块， 用于根据所述接收模块接收的上行物理信息搜索所述上行物理信息对应的 UE; 和指示发送模块， 用于在所述搜索模块搜索到所述上行物理信息对应的 UE之后， 向 所述相邻宏小区无线网络控制设备发送切换指示消息。
再一方面， 本发明实施例还提供一种无线网络控制设备， 包括： 发送模块， 用于向无 线网络控制设备的相邻家用基站发送 UE的上行物理信息； 和指示接收模块，用于接收所述 相邻家用基站在搜索到所述上行物理信息对应的 UE之后发送的切换指示消息。
与现有技术相比， 本发明实施例具有以下优点： 家用基站接收相邻宏小区无线网络控 制设备发送的该家用基站的签约 UE 的上行物理信息， 并根据该上行物理信息搜索对应的 UE, 向宏小区的无线网络控制设备发送切换指示消息， 从而触发了 UE从宏小区到家用基 站小区的切换， 使大量的不具备自搜索能力的 UE 能够进行从宏小区到家用基站小区的切 换。 附图说明
