  • the present invention relates to the field of mobile communications, and in particular, to a processing method and system when a handover to a closed subscriber group fails. Background technique
  • HNB Home NodeB
  • the home base station is deployed as a private resource for private users in private places such as homes, groups, companies, or schools. It can provide users with various high-speed wireless access services and offer preferential tariffs, while making up for existing distributed cellular wireless. Communication system coverage is insufficient.
  • the open base mode base station allows all users to access, and the home base station cell at this time is a macro cell.
  • the closed-mode home base station only allows authorized users to access, such as family members, group members, etc. These authorized users are called non-public authorized user groups or closed subscriber groups (CSG), and the authorization information is saved.
  • CSG closed subscriber groups
  • USIM card Universal Subscriber Identity Module
  • the hybrid mode home base station allows all users to access, but has preferential or preferential conditions for users belonging to the CSG user group.
  • a cell covered by a macro base station (NodeB or eNodeB) is called a macro cell, and a cell covered by a home base station is called a CSG cell, and has a CSG identity (ID).
  • the UE determines the access mode of the home base station to which the CSG cell belongs and/or the allowed CSG column stored in the USIM card.
  • the table (Allowed CSG list or CSG whitelist) information can determine whether a CSG cell allows itself to access. For a specific UE, the number of CSG cells allowed to access is usually limited, so the UE can locally save information about the CSG cells that have been accessed, called footprint/fingerprint information (footprint information), through the footprint/fingerprint information.
  • the UE can enter the CSG cell accurately and quickly during reselection and handover.
  • the home base station may use a frequency resource reserved by the operator specifically for the home base station, which is called a dedicated carrier for the CSG, or may use the same frequency resource as the macro base station, which is called a mixed carrier, and the inter-cell within the same frequency.
  • the physical layer identifier (PCI) is used.
  • PCI physical layer identifier
  • the operator reserves PCI resources for the home base station.
  • the CSG cell uses the PCI in the PCI split. Like the macro cell, the CSG cell has a physical layer identifier PCI and a Cell Global Identifier (CGI).
  • PCI Due to the limited physical layer identification, PCI cannot uniquely characterize a CSG cell with the massive deployment of the home base station; while the CGI is unique within the PLMN (Public Land Mobile Network), the UE and the macro base station are only acquired.
  • the CGI can uniquely determine a CSG cell.
  • the UE With the massive deployment of the home base station, the UE is required to switch between the macro cell and the CSG cell, or between the CSG cell and the CSG cell to meet the mobility requirement. Since the home base station is portable and is deployed in a large amount, the neighboring cell relationship is not configured between the macro cell and the CSG cell, that is, the UE cannot obtain the phase when the UE switches from the macro cell to the CSG cell. For the information of the neighboring CSG cell, the UE needs to detect the CSG ID, CGL TAC (Tracking Area Code), PLMN and other information of the CSG cell in real time to achieve the purpose of handover.
  • CSG ID CGL TAC (Tracking Area Code)
  • PLMN Packet Radio Service
  • the UE since the UE has priority or preferential rights in certain authorized CSG cells, the UE needs to implement access control during handover so that only authorized users can access the closed mode home base station cell. For the case where the handover access control fails, it is likely that the allowed CSG list reserved by the UE is not updated in time, and it is also possible that some malicious UE attempts to access the closed mode.
  • the CSG cell is entitled to enjoy the priority or preferential rights.
  • the existing protocol does not involve this problem. If the appropriate processing method is not adopted, the UE may still consider that the CSG cell is accessible, continue to send measurement reports, and the network side receives the measurement. 4

向封闭用户组小区切换失败时的处理方法及*** 技术领域
本发明涉及移动通信领域， 具体涉及向封闭用户组小区切换失败时的 处理方法及***。 背景技术
现代无线网络***建设中， 室内覆盖已经成为网络建设的重中之重， 合适的室内覆盖方案一方面可以让网络最大程度地发挥其作用， 为运营商 创造更大的价值， 另一方面也可以大大节省运营商的建网成本， 真正实现 低投入高回报。 由此， 一种叫做家庭基站 (Home NodeB, HNB)的无线接入 设备应运而生。 家庭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， 能够给用户提供各种高速无线接入服务 并提供资费上的优惠， 同时弥补已有分布式蜂窝无线通信***覆盖不足的 矛盾。
目前， 家庭基站主要有三种接入模式： 开放的、 封闭的和混合的。 开 放模式的家庭基站允许所有的用户接入， 此时的家庭基站小区就是宏小区。 封闭模式的家庭基站只允许经过授权的用户接入， 如家庭成员、 团体成员 等用户，这些经过授权的用户称为非公开授权用户组或封闭用户组 （Closed Subscriber Group , CSG) , 授权信息保存于 UE 的 USIM 卡 （Universal Subscriber Identity Module, 用户识别卡） 中。 混合模式的家庭基站允许所 有的用户接入， 但对于属于该 CSG用户组的用户享有优先或优惠的条件。 相对于宏基站 (NodeB或者 eNodeB)覆盖下的小区称为宏小区， 家庭基站覆 盖下的小区称为 CSG小区， 具有 CSG 标识（ID, identity )。 UE通过判断 CSG小区所属家庭基站的接入模式和 /或保存于 USIM卡中的允许 CSG列 表 ( Allowed CSG list或 CSG whitelist )信息， 可以判断某 CSG小区是否允 许自己接入。 对于一个特定的 UE, 允许其接入的 CSG小区通常数量有限， 因此 UE 可以本地保存那些曾经接入过的 CSG 小区的信息， 称为 footprint/fingerprint信息 (足迹信息), 通过 footprint/fingerprint信息, UE 可以在重选和切换时准确而快速的进入 CSG小区。
家庭基站可以使用运营商专门为家庭基站预留的频率资源， 称为 CSG 专用频率（ dedicated carrier ), 也可以使用与宏基站相同的频率资源称为混 合频率 (mixed carrier) ,相同频率内小区间以物理层标识 PCI ( Physical Layer Identity ) 区分， 当家庭基站和宏基站使用相同频率时， 运营商会为家庭基 站专门预留 PCI资源 （ PCI split ), CSG小区使用 PCI split内的 PCI。 与宏 小区一样， CSG 小区有一个物理层标识 PCI 和一个全局小区标识 （Cell Global Identifier, CGI )。 由于物理层标识有限， 随着家庭基站的海量部署， PCI不能唯一表征一个 CSG小区； 而 CGI在 PLMN ( Public Land Mobile Network, 公众陆地移动电话网） 范围内唯一， 因此 UE和宏基站只有获取 到 CGI才能唯一确定一个 CSG小区。
随着家庭基站的海量部署， 势必要求 UE在宏小区与 CSG小区之间， 或者在 CSG小区与 CSG小区之间切换， 以满足移动性需求。 由于家庭基站 作为即插即用的设备具有可移动性，且海量部署，一般情况下宏小区和 CSG 小区之间不会配置邻区关系， 即 UE从宏小区切换到 CSG小区时是不能获 得相邻 CSG小区的信息的， UE需要实时探测获得 CSG小区的 CSG ID、 CGL TAC ( Tracking Area Code , 跟踪区编码）、 PLMN等信息才能达到切 换的目的。 同时由于 UE在某些授权的 CSG小区具有优先或优惠的权利， 在切换时需要对 UE 实施接入控制使得只有授权的用户才能接入封闭模式 的家庭基站小区。对于切换接入控制失败的情况，很可能该 UE保留的允许 CSG列表没有及时更新， 也有可能是某些恶意的 UE企图接入封闭模式的 CSG 小区以便享受优先或优惠的权利， 现有的协议没有涉及这个问题， 如 果不采取合适的处理方法， UE可能仍然认为该 CSG小区是可以接入的， 继续发送测量 告， 网络侧收到测量4艮告可能再次向目标 CSG小区发送切 换请求， 导致接口之间的信令消耗， 影响网络的性能。 发明内容
有鉴于此， 本发明的主要目的在于提供一种向封闭用户组小区切换失 败时的处理方法及***， 用于解决 UE向同一非成员的 CSG小区切换， 导 致接口信令消耗， 降低网络性能的技术问题。 为达到上述目的， 本发明的 技术方案是这样实现的：

进一步地， 所述源基站、 或源 RNC、 或源家庭基站收到所述切换准备 失败或重定位准备失败的信令后， 所述源基站、 或源 RNC、 或源家庭基站 阻止所述待切换的 UE向具有相同封闭用户组标识（CSG ID ) 的目标家庭 基站小区发送切换要求或重定位要求信令。
基于上述方法， 本发明还提出一种向封闭用户组小区切换失败时的处 理***， 该***包括：
请求模块， 位于源基站、 或源 RNC、 或源家庭基站， 用于根据待切换 UE的测量 告选择目标 CSG小区作为切换目的小区， 并向核心网发送向 CSG小区的切换要求或重定位要求信令；所述目标 CSG小区为处于封闭模 式的 CSG小区。 接入控制模块， 位于核心网、 或目标家庭基站网关、 或目标家庭基站， 用于判断所述待切换的 UE是否为所述目标 CSG小区的授权用户或成员用 户、 或所述目标 CSG小区是否在待切换的 UE的允许 CSG列表中， 当判断 结果为否时， 通过核心网向失败处理模块发送携带非成员原因的切换准备 失败信令或重定位准备失败信令；
失败处理模块， 位于源基站、 或源 RNC、 或源家庭基站， 用于在接收 到所述切换准备失败信令或重定位准备失败信令后执行相应的切换失败处 理操作。
基于本发明的另一方面， 本发明还提出一种向封闭用户组小区切换失 败时的处理方法， 该方法包括：

步骤 404A: 目标家庭基站根据 UE的允许 CSG列表，以及自身的 CSG ID、接入模式（处于封闭模式）实施接入控制， 发现该 UE不是目标家庭基 站的成员用户 （或不在用户设备的允许 CSG 列表中）， 目标家庭基站向家 庭基站网关发送重定位失败（ Relocation Failure )信令， 在该信令中携带该 UE非成员、 或该 UE不是目标 CSG小区的成员、 或目标家庭基站 CSG ID 不在允许 CSG列表的原因。 需要说明的是， 目标家庭基站获取 UE的允许 CSG列表可以通过重定位请求信令（该信令携带该 UE的允许 CSG列表）， 或者目标家庭基站单独发送信令请求核心网下发该 UE的允许 CSG列表。
步骤 405A: 家庭基站网关向核心网发送重定位失败信令。
步骤 406A: 核心网向源 RNC或源家庭基站（向源家庭基站发送需要 通过源家庭基站所属家庭基站网关， 下面与此相同 )发送重定位准备失败 ( Relocation Preparation Failure )信令， 其中携带该 UE非成员、 或该 UE 不是目标 CSG小区的成员、或目标家庭基站 CSG ID不在允许 CSG列表的 原因。
如果由目标家庭基站网关实施接入控制：
步骤 402B: 核心网接收到重定位要求信令后， 向目标家庭基站所属的 家庭基站网关发送重定位请求（ Relocation Request )。
步骤 403B: 目标家庭基站网关根据 UE的允许 CSG列表， 以及目标 CSG小区的 CSG ID, 接入模式（封闭模式） 实施接入控制， 发现该 UE不 是目标家庭基站的成员用户 （或不在用户设备的允许 CSG 列表中）， 目标 家庭基站网关向核心网发送重定位失败（ Relocation Failure )信令， 在该信 令中携带该 UE非成员、 或该 UE不是目标 CSG小区的成员、 或目标家庭 基站 CSG ID不在允许 CSG列表的原因。 需要说明的是， 目标家庭基站网 关获取 UE的允许 CSG列表可以通过重定位请求（该信令携带该 UE的允 许 CSG列表 ), 或者目标家庭基站网关单独发送信令请求核心网下发该 UE 的允许 CSG列表。 目标家庭基站网关保存有所辖家庭基站的接入模式以及 CSG ID。
步骤 404B : 核心网向源 RNC 或源家庭基站发送重定位准备失败 ( Relocation Preparation Failure )信令， 其中携带该 UE非成员、 或该 UE 不是目标 CSG小区的成员、或目标家庭基站 CSG ID不在允许 CSG列表的 原因。
如果由核心网实施接入控制：
步骤 402C: 核心网根据 UE的允许 CSG列表， 以及目标 CSG小区的 CSG ID, 接入模式（处于封闭模式） 实施接入控制， 发现该 UE不是目标 家庭基站的成员用户 （或不在用户设备的允许 CSG 列表中）， 核心网向源 RNC或源家庭基站发送重定位准备失败（ Relocation Preparation Failure )信 令， 在该信令中携带该 UE非成员、 或该 UE不是目标 CSG小区的成员、 或目标家庭基站 CSG ID不在允许 CSG列表的原因。 需要说明的是， 核心 网可以根据家庭基站的注册流程获得家庭基站的接入模式以及 CSG ID, 也 可以通过专用信令向家庭基站网关索取家庭基站的接入模式以及 CSG ID。
源 RNC或源家庭基站收到切换准备失败信令后， 启动一定时器， 在该 定时器没有超时前， 源 RNC或源家庭基站阻止该 UE (即不再为该 UE )向 目标家庭基站发送切换要求或重定位要求信令。 在该定时器运行期间， 网 络侧和该 UE可能均已更新允许 CSG列表， 该定时期超时后， 如果仍然收 到 UE上报的该目标家庭基站小区信号很好的测量报告， 源 RNC或源家庭 基站将再向目标家庭基站发送重定位要求信令。
需要说明的是当核心网实施切换时的接入控制时， 核心网发现目标 CSG小区不在允许 CSG列表中， 核心网直接发起 NAS流程对该 UE实施 允许 CSG列表的更新， 核心网可以通过重定位准备失败携带 NAS信令， 源 RNC或源家庭基站收到该信令后，向 UE发送该 NAS信息（通过 DL direct transfer或其他可以携带 NAS的空口信令）， UE收到该 NAS信息后， 更新 本 UE的允许 CSG列表。 核心网也可以通过发送单独的 NAS信息 （ Direct Transfer )或通过其他的信令携带 NAS信息， 对 UE实施允许 CSG列表的 更新。
实施例三

由于该 UE非成员导致切换接入控制失败的流程如图 5所示。此处可能 由目标家庭基站、 或核心网实施切换时的接入控制， 具体方法与实施例一 中描述一致， 此处不再赘述。
源基站或源家庭基站收到切换准备失败消息后， 获知其非成员的原因。 由于源基站或源家庭基站通过 UE 的测量报告获知目标家庭基站小区的 CSG ID,源基站或源家庭基站阻止该 UE向具有相同 CSG ID的目标家庭基 站小区发送切换要求， 此处需要说明的是， 切换要求是源基站或源家庭基 站向目标家庭基站小区发送的， 阻止该 UE的意思是不再为该 UE向具有相 同 CSG ID的目标家庭基站小区发送切换要求。
