一种用户设备对私有小区发起操作的方法、 系统及装置
本申请要求了 2008年 4月 29日提交的、 申请号为 200810067050.6、 发 明名称为 "一种用户设备对私有小区发起操作的方法、 系统及装置" 的中国 申请的优先权，和要求了 2008年 6月 19日提交的、申请号为 200810129018.6、 发明名称为 "一种用户设备对私有小区发起操作的方法、 系统及装置" 的中 国申请的优先权， 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， 尤其涉及用户设备对私有小区发起操作的技 术。
背景技术
随着第三代 3G 移动通信技术的发展， 出现了毫微微蜂窝基站， 即 femtocell, 也被称作家用基站 （Home NodeB, HNB )或 3G接入点， 家庭室 内覆盖基站、 企业级的内部覆盖基站以及其他受限网络应运而生。 3G家用基 站可以与运营商的原有网络设备无缝连接， 大量的移动业务被家用基站所吸 收， 能够降低运营商宏蜂窝的数量， 为运营商节约设备投资费用和维护费用。
最近又引入了 CSG ( Closed Subscriber Group, 封闭签约用户组 )的概念， 签约到 CSG内、或者被 CSG的主人添加到 CSG内的用户设备，能够在该 CSG 小区内正常驻留及发起业务；而没有签约到 CSG内并且没有被 CSG主人添加 到 CSG内的用户设备， 则无法正常驻留到该 CSG小区， 也无法向该 CSG小 区发起业务。
在 3G网络中， 由于用户不知道自己能够访问哪些私有小区， 所以对私有 小区的接入限制是通过网络拒绝方式实现的， 即无论用户设备对小区是否具 有接入权限， 都可以向私有小区发起位置更新请求， 由私有网络来识别用户 是否是有权限。 对于有权限的用户， 网络允许其接入， 对于无权限的用户， 网络拒绝其接入。
目前只有小区的物理 ID和全局 ID来标识小区。 用户设备在进行小区搜 索时， 能得到小区的物理 ID, 在读该小区的广播信息时， 能获知该小区的全 局 ID, 但无法知道该小区的类型是宏小区还是 HNB小区， 更无法知道该小 区是否是自己的 CSG小区， 即用户对该小区是否具有权限。 激活态和空闲态 的用户设备都是通过信令接受的方式获知私有小区是否是自己的 CSG小区， 即用户设备向私有小区发送信令， 如果信令被接受， 则该用户设备获知该私 有小区为自己的 CSG小区， 该用户设备是该私有小区的合法用户； 当信令不 被接受时， 则该用户设备获知该私有小区不是自己的 CSG小区， 该用户设备 不是该私有小区的合法用户， 用户设备不能驻留或切换到该私有小区。 这样， 用户设备对没有权限的私有小区也会进行大量的小区测量、 接入、 切换和重 选等操作 , 增力口了 RA/TA/LA ( routing area/tracking area/local area, 路由区 /艮 踪区 /本地区） 更新的信令流以及接入、 切换和重选的信令流， 从而增大了用 户设备的耗电量和网络的信令负荷。 发明内容
有鉴于此， 本发明提供一种用户设备对私有小区发起操作的方法、 系统 及装置， 使用户设备对识别出的具有权限的私有小区发起操作， 避免了由于 用户设备无法识别私有小区， 并对不具有权限的私有小区发起操作， 导致的 用户设备耗电量增大和网络负荷增加的问题。
本发明实施例提供一种用户设备对私有小区发起操作的方法， 包括： 接 收小区标识信息， 并根据该小区标识信息识别私有小区； 根据上述小区标识 信息识别上述私有小区是否为用户设备具有权限的私有小区； 对具有权限的 私有小区发起操作。
本发明实施例还提供一种网络设备， 包括： 小区标识单元， 用于生成指 示私有小区的小区标识信息； 发送单元， 用于向用户设备发送上述小区标识 单元生成的小区标识信息。 本发明实施例还提供一种用户设备， 包括： 接收单元， 用于接收网络设 备发送的指示私有小区的小区识别信息； 识别单元， 用于根据上述小区识别 信息识别上述私有小区是否为用户设备具有权限的私有小区； 操作单元， 用 于对具有权限的私有小区发起操作。
上述技术方案通过网络侧对私有小区进行标识， 使用户设备能够识别出 小区是否为私有小区， 并对具有权限的私有小区发起操作， 避免了由于用户 设备无法识别私有小区， 并对不具有权限的私有小区发起操作， 导致的用户 耗电量增大和网络负荷增加的问题。 附图说明
图 1是本发明实施例一提供的方法流程简化示意图；
图 2是本发明实施例二提供的方法流程简化示意图；
图 3是本发明实施例三提供的通信系统和装置的结构简化示意图。 具体实施方式
下面将结合附图和具体实施例对本发明提供的技术方案进行详细介绍。 以下各实施例均以下述的场景为例进行描述： 用户终端在宏小区 001中， 该宏小区 001相邻的小区有小区 1 , 2, 3和 4,这四个小区全局 ID分别是 32, 42, 52, 62, 其中小区 1和 2是宏小区， 小区 3和 4是私有小区， 本实例以 HNB小区为例 , 小区 3和 4对应的 CSG ID分别是 11和 22。
由于现有技术中并没有对 CSG ID进行定义，所以发明本实施例提供如下 CSG ID 的构成方式包括：
( 1 ) 由小区的物理标识构成， CSG ID = PHYSICAL CELL ID。
( 2 )当全局小区标识即 GCI的位数充足的情况下， 由小区的全局标识构 成， CSG ID = GCI。
( 3 ) 由 HNB的标识构成， CSG ID = HNB ID, 此时一个 CSG对应一个
HNB。 ( 4 ) 由 HNB的标识和小区的标识联合构成， CSG ID = HNB ID + CELL ID; 一个 CSG可以包括多个 HNB, 而该 CSG包含的 HNB小区可以是在物 理上连续的或者是物理上不连续的； CELL ID根据 CSG所辖的小区数量使用 不同的标识长度。 一个 HNB也可以属于不同的 CSG, 并且 HNB ID可以根据 小区的大小选择使用不同的标识长度。
( 5 ) 由跟踪区标识 /路由区标识 /本地区标识联合构成， 一个 CSG对应一 个 TA/RA/LA , CSG ID = TA ID/RA ID/LA ID。
( 6 )由跟踪区标识 /路由区标识 /本地区标识和小区的标识联合构成， CSG ID = TA ID/RA ID/LA ID + CELL ID, 这里的 CELL ID是小区在给定的 TA ID/RA ID/LA ID下的唯一的编号； TA ID/RA ID/LA ID和 CELL ID的长度分配 可以不是固定的， 根据一个 TA/RA/LA下控制的小区多少而改变。
( 7 ) 由公众陆地移动通信网标识、 HNB的标识和小区的标识联合构成， CSG ID = PLMN ID + HNB ID + CELL ID, 这里的 CELL ID是小区在给定的 HNB下的唯一的编号， 这种组成是在 CSG ID的位数充足的情况下， 并且在 任何场景下都适用， 同样也适用于 GCI。
( 8 ) 由公众陆地移动通信网标识和跟踪区标识 /路由区标识 /本地区标识 联合构成， 一个 CSG对应一个 TA/RA/LA, CSG ID = PLMN ID + TA ID/RA ID/LA ID。
( 9 ) 由公众陆地移动通信网标识、 跟踪区标识 /路由区标识 /本地区标识 和小区标识联合构成， CSG ID = PLMN ID + TA ID/RA ID/LA ID + CELL ID , 这里的 CELL ID是小区在给定的 TA/RA/LA下的唯一的编号。
另外， 引入 HNB后， 由于 HNB的数量很大， 对于 HNB小区， GCI的构 成方式包括：
( 1 ) CSG ID+HNB ID+CELL ID,这里的 CELL ID是小区在给定的 HNB 下的唯一的编号；
( 2 ) HNB ID+CELL ID, 这里的 CELL ID是小区在给定的 HNB下的唯 一的编号；
( 3 ) TA ID/RA ID/LA ID+CELL ID, 这里的 CELL ID是小区在给定的 TA/RA/LA下的唯一的编号；
( 4 ) TA ID/RA ID/LA ID的部分位 + CELL ID, 这里的 CELL ID是小区 在给定的 TA/RA/LA下的唯一的编号；
( 5 ) CSG ID + CELL ID, 这里的 CELL ID是小区在给定的 CSG下的唯 一的编号， CSG ID和 CELL ID的长度分配可以是灵活的， 根据一个 CSG下 控制的小区多少而改变。
下面进一步介绍 CSG ID的应用：
( 1 )无线接入网络侧对 CELL— DCH态的 UMTS手机进行移动管理时， 网络需要知道手机 CSG白名单中的 CSG ID信息（至少部分白名单内容）， 网 络通过对邻区 CSG ID和手机白名单中允许的 CSG ID的进行比较， 从而进行 准确的切换判决。 上述 CSG ID信息包括：
a.从核心网到无线网络侧的信令， 其中包含部分手机的上下文信息， 网络 在手机被邀请接入 CSG或 CSG邀请超时后， 更新这些信息
b.来自 CSG基站的信令， 例如， 在切换准备消息中， 被告知哪些手机被 邀请到这个 CSG。
网络通过后台 O&M 的配置可以预知上述信息， 或者通过和相邻 CSG基 站的信令交互记住上述信息。
( 2 )对于非 CELL— DCH态的 UMTS手机和其它的 LTE类的手机， 网络 通过 BCCH ( Broadcast Control Channel, 广播控制信道） 中的 SIB ( System Information Block, 系统信息组） 消息来告知手机 CSG ID。 手机在进行移动 性判决时， 通过对比手机中存储的 CSG白名单中的 CSG ID和 BCCH上广播 的 CSG ID, 来决定手机是否可以驻留在该小区。
对于 HNB小区，根据上述 CSG ID或 GCI的构成关系，通过 BCCH的广 播消息发送构成关系中的部分标识， 或标识的组成部分， 再通过上述广播的 标识和上述 CSG ID或 GCI的构成关系， 推导出该构成关系中未广播标识， 这样不用全部广播一个构成关系中的全部标识， 以减少 BCCH的负荷。
例如： 当 CGI ( 30到 32位） 由 CSG ID ( 28位） + CELL ID ( 3到 5位） 构成时， 在 BCCH广播的系统信息里只广播 CGI和 CELL ID, 这样用户设备 可以根据上述构成关系推出此相应的 CSG ID;或者在在 BCCH广播的系统信 息里只广播 3到 5位的 CELL ID和 28位的 CSG ID, 用户设备可以根据上述 构成关系推导获得相应的 CGI,这样比同时广播 30到 32位的 CGI和 28位的 CSG ID, 在空口减少至少 28bit的信息量。
再例如： 当 CSG ID 由 TA ID/RA ID/LA ID组成 , 那么在 BCCH广播的 系统信息里只广播 CSG ID或 TA ID/RA ID/LA ID, 再根据上述组成关系即可 获知未广播的标识， 不用两个都广播， 从而节省了空口的信息量。
对于能够读取邻区的 CSG ID的连接态手机，那么可以通过对比手机里存 储的 CSG白名单中的 CSG ID来决定手机是否可以切到该小区。 对于不能读 取邻区的 CSG ID的手机， 例如 CELL— DCH态的 UMTS手机， 那么应该在移 动判决前就应该获取邻区的 CSG ID。
上述手机里的 CSG白名单可以由网络信令来管理， 一个象征性的机制通 过超时设定等， NAS信令可能会受到影响， 如这些场景下： 附着,寻呼以及后 续的信令流等。
另外， 手工选择也是对用户设备中 CSG白名单的一种使用机制。
实施例一
本实施例中， 网络侧通过向用户设备发送物理小区标识， 指示小区是否 为私有小区。
如图 1所示， 本实施例提供的具体方法如下：
步骤 101 , 网络侧将小区扰码中的部分扰码序列作为 HNB小区的专用扰 码， 向用户设备发送能够标识小区是否为 HNB的物理小区标识， 即经过扰码 序列划分后的小区物理 ID。 我们知道， 小区的扰码总共有 218比特位， 即， 262,143个， 为了小区快 速切换， 取其中的 k = 0, 1, ... , 8191个序列， 这些小区被分成了扰码序列 512 个组，每个小区有且仅有一个主扰码。所以，可以划出部分扰码序列作为 HNB 小区的专用扰码， 通过采用的科学的网络规划技术， 使一个相关区域内， 一 个扰码唯一对应一个 CSG或者一个 HNB小区。 例如， 把从 482到 512的扰 码序列作为 HNB小区的专用扰码，扰码划分可以通过协议规定，并通过 BCCH 信令或专用信令知会用户设备。 本实施例中上述小区 1、 2、 3和 4的物理 ID 分别是 120, 220, 486和 489, 这样， 当用户设备搜索到从 482到 512的扰码 时 , 就知道这些扰码对应的小区是 HNB小区。
另外， 也可以在保证手机的小区搜索速度得到保证的情况下， 扩展目前 的使用的小区扰码， 取出扩展部分中的部分扰码序列作为私有小区的专用扰 码。 私有小区专用扰码的配置， 可以是静态的， 或者动态的， 或者是半动态 的。 如果上述私有小区专用扰码的配置是动态的或者是半动态的， 那么配置 动态改变的方式可以是周期触发的， 或事件触发的， 或周期因子和事件因子 综合考虑触发的。 同时， 私有小区专用扰码的配置参数可以通过 BCCH信道 广播， 或专用信令来通知用户终端， 不同网络控制器需要通过 Iur/X2 口来交 换这些信息或者通过 Iu转发这些配置参数信息。
步骤 102, 用户设备根据上述物理小区标识识别 HNB小区， 并对具有权 限的 HNB小区发起操作。
当用户设备不具有 HNB权限时， 如果搜索到物理 ID为 486和 489的小 区， 便根据扰码序列的划分识别出这两个小区为 HNB小区， 不对上述两个小 区发起操作； 如果搜索到物理 ID为 120和 220的小区， 则继续发起相关的接 入、 测量、 测量结果上报、 以及后续的小区重选和切换等操作。
当用户设备具有 HNB权限，且用户设备的白名单里指示其可进入的合法 小区的物理 ID是 489, 当用户设备搜索到物理 ID为 486和 489的小区时，根 据扰码序列的划分识别出这两个小区是 HNB小区， 然后， 用户设备将上述获 取的两个物理 ID和自己白名单里指示其可进入的合法小区的物理 ID进行对 比， 当识别出物理 ID为 489的小区为自己有权限的小区时， 向物理 ID为 489 的小区发起相关的接入、 测量、 测量结果上报、 以及后续的小区重选和切换 等操作， 对物理 ID为 486的小区不发起操作。
另外需要说明， 通过扰码复用可以解决网络规划和物理 ID数量受限的问 题， 使在一个相关区域内， 一个扰码不唯一对应一个 CSG或者一个 HNB小 区。 这种情况下， 当用户设备具有 HNB小区的权限时， 由于物理 ID的复用， 用户设备的白名单里指示其可进入的合法小区的 CSG ID是 22。 当用户设备 搜索到物理 ID为 486和 489的小区时， 根据扰码序列的划分识别出这是两个 小区为 HNB小区， 然后进一步读取相邻小区的系统广播信息， 获取这两个小 区对应的 CSG ID分别是 11和 22。 用户设备将获取的 CSG ID和自己白名单 里指示其可进入的合法小区的 CSG ID进行对比， 对 CSG ID是 22的小区 4 发起相关的接入、 测量、 测量结果上报、 以及后续的小区重选和切换等操作。
本实施例提供的上述技术方案， 使用户设备对识别出的具有权限的私有 小区发起操作， 避免了由于用户设备对不具有权限的私有小区发起操作， 导 致的用户设备耗电量增大和网络负荷增加的问题。
实施例二
本实施例中， 网络侧通过向用户设备发送 HNB小区类型指示信息， 指示 小区是否为私有小区。 本实施例提供的方法， 如图 2所示， 具体包括：
步骤 201 , 网络侧向用户设备发送 HNB小区类型指示信息。 该私有小区 类型指示信息包括： HNB小区列表， HNB小区类型指示信元、 带有私有小区 信息的系统信息组 SIB, 和带有私有小区类型指示比特的小区 ID。
下面进行具体介绍：
( 1 ) HNB小区类型指示信息为： HNB小区列表。
网络测通过 HNB小区列表标识 HNB小区 ,即以单独的 HNB小区列表来 标识 HNB小区。 例如， 在 SIB中从宏小区列表分离出一个单独的 HNB小区 列表项， 这样， 用户设备根据从 BCCH上接收的 SIB消息中的列表格式， 存 储并更新用户设备中的小区列表变量， 例如 CELL— LIST; 通过协议规定， 用 户设备明确列表中各小区的属性。 网络将小区 1和 2的信息存于 SIB中的同 频测量系统消息 ( Intra- frequency/Inter-frequency/Inter-RAT measurement system information ) 中的小区信息列表 ( cell info list ) 中， 而将小区 3和 4的信息存 于 SIB 中的同频测量系统消息 （ Intra-frequency /Inter-frequency/Inter-RAT measurement system information ) 中的 HNB小区信息歹1 J表 ( cell info list for HNB ) 中。
( 2 ) HNB小区类型指示信息为： HNB小区类型指示信元。
网络测通过 HNB小区类型指示信元标识 HNB小区。 即网络侧在向用户 设备下发的消息中， 增加一个专门指示小区是 HNB 小区还是宏小区的信元 ( infomation element, IE )。
例如， 网络侧在异频小区列表信息 （ Inter-frequency cell id ) 的 IE中添加 "小区类型" IE。 可以根据系统定义上述 "小区类型" IE, 如定义 "小区类型" 取值为 0表示宏小区； "小区类型" 取值为 1表示 HNB小区。
用户设备通过这个 "小区类型" IE, 识别小区是否为 HNB小区。 当确认 小区是宏小区时， 用户设备保存该小区的相关信息， 例如在在变量 CELL— INFO— LIST中变量中保存。 当用户设备通过这个标识 IE, 确认小区是 HNB小区时， 如果用户设备具有对 HNB小区的自搜索能力， 则忽略这个小 区的信息， 如果用户设备不具有对 HNB小区的自搜索能力， 则保存该小区的 相关信息， 例如在在变量 CELL— INFO— LIST中变量中保存。
( 3 ) HNB小区类型指示信息为： 带有私有小区信息的系统信息组 SIB。 在 BCCH广播的系统消息中， 新加一个 SIB, 专门用来指示 HNB小区的 信息。 如果用户设备从 BCCH广播的系统消息中获得上述新增 SIB, 则可以 识别小区为 HNB小区。
( 4 ) HNB小区类型指示信息为： 带有私有小区类型指示比特的小区 ID。 例如， 在小区 ID (全局小区 ID或物理小区 ID )前加上一个 IBit标识， 通过 该标识来标识该小区是否是宏小区或 HNB小区。
步骤 202, 用户设备根据上述 HNB小区类型指示信息识别 HNB小区， 并对具有权限的私有小区发起操作。 具体包括以下情况：
1、 当用户设备不具有 HNB权限时， 如果用户设备根据上述 HNB小区类 型指示信息识别出 HNB小区， 例如小区 3、 4, 则不对小区 3、 4发起操作； 如果根据上述 HNB小区类型指示信息识别出宏小区， 例如小区 1、 2, 则不需 要进一步读取该邻区的系统广播信息， 去获取到对应的 CSG ID或者 GCI, 直 接向相关小区发起接入、 测量、 测量结果上报、 以及后续的小区重选和切换 等操作。
2、 当用户设备具有 HNB权限， 用户设备的白名单里指示其可进入的合 法小区的 CSG ID是 22时。 如果：
( 1 )用户设备具有自搜索能力。
a.当用户设备根据上述 HNB小区类型指示信息识别出小区为 HNB小区， 例如小区 3和 4, 则通过自搜索能力对邻区进行测量， 搜索获得小区 3 , 4的 物理 ID,并进一步读取该邻区的系统广播信息，获取小区 3 , 4对应的 CSG ID 分别是 11 , 22。 用户设备通过将获取的 CSG ID和自己白名单里指示其可进 入的合法小区的 CSG ID进行对比， 获知 CSG ID为 22的小区 4为自己具有 权限的 HNB小区， 用户设备对小区 4发起接入、 测量、 测量结果上报、 以及 后续的小区重选和切换等操作。
b.当用户设备根据上述 HNB小区类型指示信息识别出小区为宏小区， 例 如小区 1和 2, 才艮据 NCL获取小区的物理 ID, 例如小区 1 , 2的物理 ID分别 为 120, 220。 根据该物理 ID搜索到相关小区后， 不需要进一步读取该邻区的 系统广播信息， 去获取到对应的 CSG ID或者 GCI, 而是直接根据物理 ID发 起相关的接入、 测量、 测量结果上报、 以及后续的小区重选和切换等操作。
( 2 )用户设备不具有自搜索能力。 a.当用户设备根据上述 HNB小区类型指示信息识别出小区为 HNB小区， 例如小区 3和 4; 则根据 NCL获取小区的物理 ID, 然后， 进一步读取该邻区 的系统广播信息， 获取到对应的 CSG ID, 例如小区 3和 4的 CSG ID分别是 11 , 22。 用户设备将获取的 CSG ID和自己白名单里指示其可进入的合法小区 的 CSG ID进行对比， 获知 CSG ID为 22的小区 4为自己具有权限的 HNB小 区， 用户设备对小区 4发起接入、 测量、 测量结果上报、 以及后续的小区重 选和切换等操作。
b. 当用户设备根据上述 HNB小区类型指示信息识别出小区为宏小区，例 如小区 1和 2, 具体操作方法同 （2 ) b, 此处不再贅述。
3、 当用户设备具有 HNB权利， 用户设备的白名单里指示其可进入的合 法小区的 GCI是 62, 且该用户设备具有自搜索能力时。
a.当用户设备根据上述 HNB小区类型指示信息识别出小区为 HNB小区， 例如小区 3和 4; 则根据 NCL获取小区的物理 ID, 然后， 进一步读取该邻区 的系统广播信息， 获取到对应的全局小区 ID即 GCI, 分别是 52, 62。 用户设 备将获取的 GCI和自己白名单里指示其可进入的合法小区的 GCI进行对比， 获知 GCI为 62的小区 4为自己具有权限的 HNB小区， 用户设备对小区 4发 起接入、 测量、 测量结果上报、 以及后续的小区重选和切换等操作。
b.当用户设备根据上述 HNB小区类型指示信息识别出小区为宏小区， 例 如小区 1和 2, 具体操作方法同 （2 ) b, 此处不再贅述。
本实施例提供的上述技术方案， 使用户设备对识别出的具有权限的私有 小区发起操作， 避免了由于用户设备对不具有权限的私有小区发起操作， 导 致的用户设备耗电量增大和网络负荷增加的问题。
