Definitions
- the present invention relates to the field of mobile communications technologies, and in particular, to a list update method, a mobility management unit, a user equipment, and a home base station.
- a home base station (Home NodeB, referred to as a ⁇ ) or an evolved home base station (Home eNodeB, called a HeNB) is a small, low-power base station deployed in indoor places such as homes and offices, and can provide users with Higher service rates and lower costs for using high-rate services, while also making up for the deficiencies of existing distributed cellular wireless communication systems.
- the home base station can be applied in a third generation (3rd Generation) or a Long Term Evolution (LTE) mobile communication network.
- 3rd Generation Third Generation
- LTE Long Term Evolution
- a new network element that is, a home base station gateway, is introduced in the radio access network.
- the main functions performed by the home base station gateway include: verifying the security of the home base station, processing the registration of the home base station, performing operation and maintenance management on the home base station, configuring and controlling the home base station according to the operator's requirements, and managing data of the core network and the home base station.
- 1 is a network diagram of a home base station network in a 3G mobile communication network.
- the 3G home base station is connected to the home base station gateway through a newly defined Iuh interface, and the home base station gateway provides IuPS and IuCs interfaces to the core network packet domain and the circuit domain.
- the home base station gateway is mandatory to shield the impact on the terminal and the network side after the home base station is introduced.
- the home base station gateway is optional. Therefore, the LTE home base station and the core network are connected in two ways. One is that the home base station and the core network element are directly connected, and the other is the home base station through the gateway and the core network. The elements are connected, as shown in Figures 2 and 3, respectively.
- the home base station gateway may not integrate the user plane function. As shown in FIG. 4, the user plane is directly established between the home base station and the core network user plane gateway, so that the user plane is flattened. The data transmission delay is reduced.
- the Closed Subscriber Grou is a concept introduced after the introduction of a home base station.
- a family or a user inside an enterprise forms a closed user group.
- Each closed subscriber group is identified by a CSG ID (identification), and the home base station that is the user's monthly subscription within each closed subscriber group has the same CSG ID.
- the user can access the home base station corresponding to the multiple closed user groups by signing with the operator, wherein the identifier of the closed user group that allows the user to access is saved in the list of allowed closed user groups, and the identifier list is saved in the user equipment. (User Equipment, called UE) and the home user data server on the network side.
- UE User Equipment
- the UE can use the CSG ID list to allow the UE to select the radio cell, and the home base station will notify the UE of the CSG ID and the usage mode to which the UE belongs, and if the UE finds that the home base station is closed after acquiring the broadcast message.
- the mode is used, and the CSG ID corresponding to the home base station is not in the list of allowed closed user group identifiers saved by the home base station, and the UE determines that the home base station cell is not suitable for access and automatically selects other cells suitable for access. Avoid frequent UE access attempts and reduce battery and air interface resource consumption.
- the home subscriber data server on the network side transmits the list of allowed closed subscriber groups subscribed by the subscriber to the mobility management unit of the core network.
- the core network mobility management unit uses the list to perform access control on the UE. If the UE accesses the core network from a closed mode home base station that is not authorized by 4, the core network rejects access by such users.
- the home base station can also be used as a normal base station. At this time, the access mode of the home base station is (OPEN) open mode. In this mode, the home base station can be accessed by any user. For the user accessing from this mode, the mobility management entity does not need to access the access user.
- the home base station can have a hybrid mode, adopt closed mode access for some users, and adopt a development mode for some users.
- the home base station For users who have authorized access to the home base station, they can be classified into temporary authorized access and permanent 4 authorized access according to the wishes of the home base station administrator. Users who temporarily grant access cannot access a certain CSG ID after a certain period of time. The home base station to which the identity belongs is identified, and even the user who is permanently authorized to access can immediately cancel the access right according to the wishes of the home base station manager. At present, the duration of the temporary user access is allowed as the subscription data of the user.
- the home data server sends the subscription data to the core network mobility management unit, and the core network mobility management unit saves the information.
- the core network mobility management unit When the UE is in the connected state, if the duration of the home base station accessed by the temporary user has timed out, the core network mobility management unit removes the CSG identifier that has timed out from the user's allowed access CSG identification list (also referred to as a white table). Deleted.
- the network side does not notify the UE of the operation performed by itself, and therefore, the operation will cause the UE and the network side to allow the access CSG identification list to be out of synchronization.
- the UE will not be able to operate using the latest allowed access CSG identification list, which may cause erroneous cell reselection, measurement report generation, invalid access attempt and waste of radio resources.
- the operation on the network side may cause the user to be handed over to a non-CSG cell. Since the policies such as charging between the home base station and the ordinary base station may be different, the user may not want to switch to the ordinary base station with a higher rate. However, in the current processing mode, the UE does not know the reason for the handover at this time, and cannot present the handover reason to the user. Therefore, the user cannot decide whether to use the ordinary base station according to different situations, thereby lowering the user body. risk.
- the present invention provides a list update method, a mobility management unit, and a user equipment, which are used to solve the problem that the UE and the network side allow the access CSG identifier list to be out of synchronization.
- the list updating method includes: in a case where it is determined that the camping duration of the user equipment at the home base station exceeds a preset threshold, the mobility management unit notifies the user equipment that the currently accessed CSG is unavailable, so that the user equipment deletes its local Allows access to the identifier in the CSG identification list that corresponds to the above CSG. Further, after the user equipment is notified that the CSG is unavailable, the method further includes: receiving, by the user equipment, the foregoing notification by the mobility management unit, and deleting the identifier of the CSG from the allowed access CSG identifier list.
- a mobility management unit is provided.
- the mobility management unit includes: a determination module and a notification module.
- the determining module is configured to determine whether the resident time of the user equipment that is accessed by the temporary user of the CSG exceeds a preset threshold in the home base station corresponding to the CSG, and if the determination is yes, the notification module is triggered; Sending a notification to the user equipment notifying the user that the CSG is unavailable.
- a user equipment is provided.
- the user equipment according to the present invention includes: a receiving module and an updating module.
- the receiving module is configured to receive a notification sent by the mobility management unit, where the notification is used to indicate that the user equipment is currently accessed.
- a home base station includes: a receiving module and a transmitting module.
- the receiving module is configured to receive a handover request message sent by the mobility management unit, where the handover request message carries indication information indicating that the CSG currently accessed by the user equipment is unavailable, and the sending module is configured to receive, according to the receiving module, The foregoing switching request message sends a handover command to the user equipment, where the handover command carries the indication information.
- the mobility management unit when the UE accesses the home base station corresponding to the CSG as a temporary user of the CSG, when the UE stays at the home base station (that is, the duration of the UE accessing the home base station) exceeds a preset.
- the mobility management unit notifies the UE that the currently accessed CSG is unavailable, so that the UE can save the allowed access to the CSG identifier list corresponding to the CSG, so that the UE and the network side allow access to the CSG identifier list.
- Synchronization avoids the waste of radio resources by the UE due to incorrect cell reselection, access 4 advertisement generation, invalid access attempts, etc., so that the user can decide whether to use the ordinary base station according to different situations, thereby improving the user.

用户设备及家^^站 User equipment and home ^^ station
技术领域 本发明涉及移动通信技术领域, 尤其涉及一种列表更新方法、 移动管理 单元、 用户设备及家庭基站。 背景技术 家庭基站 (Home NodeB , 筒称为 ΗΝΒ ) 或演进的家庭基站 (Home eNodeB, 筒称为 HeNB ) 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, 可以为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, 还可以弥补现有分布式蜂窝无线通信***覆盖的不足。 家庭基站可以应用在第三代(3rd Generation, 筒称为 3G ) 或者长期演 进 ( Long Term Evolution, 筒称为 LTE ) 移动通信网络中。 为了便于对家庭 基站进行管理, 在无线接入网引入了一个新网元, 即家庭基站网关。 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、 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。 图 1是 3G移动通信网络中家庭基站网络架构图, 3G家庭基站通过新 定义的 Iuh接口连接至家庭基站网关, 家庭基站网关提供到核心网分组域和 电路域的 IuPS和 IuCs接口。 对于 3G网络, 家庭基站网关为必选部署, 用 以屏蔽引入家庭基站后对终端和网络侧的影响。对于 LTE网络家庭基站网关 为可选部署, 因此, LTE家庭基站和核心网连接有两种方式, 一种是家庭基 站和核心网网元直接相连, 另一种是家庭基站通过网关和核心网网元相连, 分别如图 2、 3所示。 对于图 3所示引入家庭基站网关的场景, 家庭基站网 关可以不集成用户面功能, 如图 4所示, 家庭基站和核心网用户面网关间直 接建立用户面, 这样可以使用户面扁平化, 数据传输时延减小。 闭合用户组 ( Closed Subscriber Grou , 筒称为 CSG ) 是引入家庭基站 后提出的概念。通常一个家庭或者一个企业内部的用户组成一个闭合用户组,
每个闭合用户组以 CSG ID (标识) 进行标识 , 在每个闭合用户组内为用户 月 务的家庭基站具有相同的 CSG ID。 用户通过与运营商签约可以接入到多个闭合用户组所对应的家庭基站,其 中 , 允许用户接入的闭合用户组的标识保存在允许闭合用户组标识列表中 , 该 标识列表保存在用户设备 ( User Equipment , 筒称为 UE )和网络侧的归属用户 数据服务器中。 UE利用其允许接入 CSG标识列表可以进行无线小区的选择, 而家庭基站将通过广播的方式将其所属的 CSG ID以及使用模式通知给 UE, UE 获取到广播消息后如果发现该家庭基站为闭合使用模式, 并且, 该家庭基 站对应的 CSG ID不在自身保存的允许闭合用户组标识列表中 , 则 UE确定该 家庭基站小区不适合接入而自动选择其他适合接入的蜂窝, 通过这种方式可以 避免 UE频繁的进行接入尝试, 降低电池和空口资源的消耗。 当用户进行初始 化接入的时候 , 网络侧的归属用户数据服务器将用户签约的允许闭合用户组列 表发送到核心网的移动性管理单元。 核心网移动性管理单元利用该列表对 UE 进行接入控制。 如果 UE从未 4受权的闭合模式家庭基站访问核心网, 则核心网 拒绝该类用户的接入。 家庭基站也可以作为普通基站使用, 此时, 家庭基站的 接入模式为 (OPEN ) 开放模式。 该模式下, 家庭基站可以被任何用户接入, 从这种模式接入的用户, 移动管理实体也不需要对接入的用户^ 接入控制。 同 样地, 家庭基站可以有混合模式, 对一部分用户采用闭合模式接入, 对一部分 用户采用开发模式。 对于已授权访问家庭基站的用户,根据家庭基站管理者的意愿可以分为临 时授权访问和永久 4受权访问两种, 临时授权访问的用户在一定的时间以后就不 可以再接入某个 CSG ID标识所属的家庭基站, 即使是永久授权访问的用户也 可以根据家庭基站管理者的意愿即时取消访问权利。 目前, 允许临时用户接入的时长作为用户的签约数据, 在 UE接入网络的 时候归属用户数据服务器将签约数据下发到核心网移动性管理单元, 核心网移 动性管理单元保存该信息。 当 UE处于连接态时 , 如果临时用户所接入的家庭 基站的时长已经超时, 则核心网移动性管理单元将已经超时的 CSG 标识从用 户的允许接入 CSG标识列表(也称作白表) 中删除。 但是, 在现有方案中, 网络侧并不会将自己所执行的操作通知给 UE, 因 此, 该操作将导致 UE和网络侧的允许接入 CSG标识列表不同步。 进而, 一方 面将导致 UE不能使用最新的允许接入 CSG标识列表进行操作 ,从而可能造成 错误的小区重选、 测量报告生成、 无效的接入尝试而浪费无线资源。 另一方面,
网络侧的操作可能导致用户被切换到一个非 CSG 小区, 由于家庭基站和普通 基站之间的计费等策略可能不相同, 而用户可能并不希望切换到费率较高的普 通基站。 但当前的处理方式中, UE 并不知道此时切换的原因, 也无法将切换 原因呈现给用户, 因此,用户不能才艮据不同的情况决定是否要使用普通的基站 , 从而降氏用户体 -险。 发明内容 有鉴于此, 本发明提供了一种列表更新方法、 移动管理单元及用户设备, 用以解决现有技术中由于 UE和网络侧的允许接入 CSG标识列表不同步,而导 致 UE错误的小区重选等造成的无线资源的浪费 , 以及用户不能才艮据不同的情 况决定是否使用普通的基站而造成用户体验降低的问题。 才艮据本发明的一个方面,提供了一种列表更新方法, 该方法用于在用户设 备处于连接状态下更新用户设备的允许 CSG 标识列表, 其中, 该用户设备作 为 CSG的临时用户接入 CSG对应的家庭基站。 根据本发明的列表更新方法包括:在确定用户设备在家庭基站的驻留时长 超过预设阈值的情况下, 移动管理单元通知用户设备当前接入的 CSG不可用, 以使用户设备删除其本地的允许接入 CSG 标识列表中对应于上述 CSG 的标 识。 进一步地, 在通知用户设备上述 CSG不可用之后, 该方法还包括: 用户 设备接收移动管理单元的上述通知, 将上述 CSG的标识从允许接入 CSG标识 列表中删除。 才艮据本发明的另一个方面, 提供了一种移动管理单元。 才艮据本发明的移动管理单元包括:判断模块和通知模块。其中,判断模块, 用于判断作为 CSG的临时用户接入的用户设备在该 CSG对应的家庭基站的驻 留时长是否超过预设阈值, 在判断为是的情况下触发通知模块; 通知模块, 用 于向用户设备发送通知, 通知用户设备上述 CSG不可用。 根据本发明的再一个方面, 提供了一种用户设备。 根据本发明的用户设备包括: 接收模块和更新模块。 其中, 接收模块, 用 于接收移动管理单元发送的通知, 其中, 该通知用于指示用户设备当前接入的

BACKGROUND A home base station (Home NodeB, referred to as a ΗΝΒ) or an evolved home base station (Home eNodeB, called a HeNB) is a small, low-power base station deployed in indoor places such as homes and offices, and can provide users with Higher service rates and lower costs for using high-rate services, while also making up for the deficiencies of existing distributed cellular wireless communication systems. The home base station can be applied in a third generation (3rd Generation) or a Long Term Evolution (LTE) mobile communication network. In order to facilitate management of the home base station, a new network element, that is, a home base station gateway, is introduced in the radio access network. The main functions performed by the home base station gateway include: verifying the security of the home base station, processing the registration of the home base station, performing operation and maintenance management on the home base station, configuring and controlling the home base station according to the operator's requirements, and managing data of the core network and the home base station. 1 is a network diagram of a home base station network in a 3G mobile communication network. The 3G home base station is connected to the home base station gateway through a newly defined Iuh interface, and the home base station gateway provides IuPS and IuCs interfaces to the core network packet domain and the circuit domain. For a 3G network, the home base station gateway is mandatory to shield the impact on the terminal and the network side after the home base station is introduced. For the LTE network, the home base station gateway is optional. Therefore, the LTE home base station and the core network are connected in two ways. One is that the home base station and the core network element are directly connected, and the other is the home base station through the gateway and the core network. The elements are connected, as shown in Figures 2 and 3, respectively. In the scenario of the home base station gateway shown in FIG. 3, the home base station gateway may not integrate the user plane function. As shown in FIG. 4, the user plane is directly established between the home base station and the core network user plane gateway, so that the user plane is flattened. The data transmission delay is reduced. The Closed Subscriber Grou (CSG) is a concept introduced after the introduction of a home base station. Usually a family or a user inside an enterprise forms a closed user group. Each closed subscriber group is identified by a CSG ID (identification), and the home base station that is the user's monthly subscription within each closed subscriber group has the same CSG ID. The user can access the home base station corresponding to the multiple closed user groups by signing with the operator, wherein the identifier of the closed user group that allows the user to access is saved in the list of allowed closed user groups, and the identifier list is saved in the user equipment. (User Equipment, called UE) and the home user data server on the network side. The UE can use the CSG ID list to allow the UE to select the radio cell, and the home base station will notify the UE of the CSG ID and the usage mode to which the UE belongs, and if the UE finds that the home base station is closed after acquiring the broadcast message. The mode is used, and the CSG ID corresponding to the home base station is not in the list of allowed closed user group identifiers saved by the home base station, and the UE determines that the home base station cell is not suitable for access and automatically selects other cells suitable for access. Avoid frequent UE access attempts and reduce battery and air interface resource consumption. When the user performs initial access, the home subscriber data server on the network side transmits the list of allowed closed subscriber groups subscribed by the subscriber to the mobility management unit of the core network. The core network mobility management unit uses the list to perform access control on the UE. If the UE accesses the core network from a closed mode home base station that is not authorized by 4, the core network rejects access by such users. The home base station can also be used as a normal base station. At this time, the access mode of the home base station is (OPEN) open mode. In this mode, the home base station can be accessed by any user. For the user accessing from this mode, the mobility management entity does not need to access the access user. Similarly, the home base station can have a hybrid mode, adopt closed mode access for some users, and adopt a development mode for some users. For users who have authorized access to the home base station, they can be classified into temporary authorized access and permanent 4 authorized access according to the wishes of the home base station administrator. Users who temporarily grant access cannot access a certain CSG ID after a certain period of time. The home base station to which the identity belongs is identified, and even the user who is permanently authorized to access can immediately cancel the access right according to the wishes of the home base station manager. At present, the duration of the temporary user access is allowed as the subscription data of the user. When the UE accesses the network, the home data server sends the subscription data to the core network mobility management unit, and the core network mobility management unit saves the information. When the UE is in the connected state, if the duration of the home base station accessed by the temporary user has timed out, the core network mobility management unit removes the CSG identifier that has timed out from the user's allowed access CSG identification list (also referred to as a white table). Deleted. However, in the existing solution, the network side does not notify the UE of the operation performed by itself, and therefore, the operation will cause the UE and the network side to allow the access CSG identification list to be out of synchronization. Furthermore, on the one hand, the UE will not be able to operate using the latest allowed access CSG identification list, which may cause erroneous cell reselection, measurement report generation, invalid access attempt and waste of radio resources. on the other hand, The operation on the network side may cause the user to be handed over to a non-CSG cell. Since the policies such as charging between the home base station and the ordinary base station may be different, the user may not want to switch to the ordinary base station with a higher rate. However, in the current processing mode, the UE does not know the reason for the handover at this time, and cannot present the handover reason to the user. Therefore, the user cannot decide whether to use the ordinary base station according to different situations, thereby lowering the user body. risk. SUMMARY OF THE INVENTION In view of this, the present invention provides a list update method, a mobility management unit, and a user equipment, which are used to solve the problem that the UE and the network side allow the access CSG identifier list to be out of synchronization. The waste of radio resources caused by cell reselection and the like, and the fact that the user cannot decide whether to use an ordinary base station according to different situations and cause a decrease in user experience. According to an aspect of the present invention, there is provided a method for updating a list of allowed CSG identifiers of a user equipment when the user equipment is in a connected state, wherein the user equipment accesses the CSG as a temporary user of the CSG. Corresponding home base station. The list updating method according to the present invention includes: in a case where it is determined that the camping duration of the user equipment at the home base station exceeds a preset threshold, the mobility management unit notifies the user equipment that the currently accessed CSG is unavailable, so that the user equipment deletes its local Allows access to the identifier in the CSG identification list that corresponds to the above CSG. Further, after the user equipment is notified that the CSG is unavailable, the method further includes: receiving, by the user equipment, the foregoing notification by the mobility management unit, and deleting the identifier of the CSG from the allowed access CSG identifier list. According to another aspect of the present invention, a mobility management unit is provided. The mobility management unit according to the present invention includes: a determination module and a notification module. The determining module is configured to determine whether the resident time of the user equipment that is accessed by the temporary user of the CSG exceeds a preset threshold in the home base station corresponding to the CSG, and if the determination is yes, the notification module is triggered; Sending a notification to the user equipment notifying the user that the CSG is unavailable. According to still another aspect of the present invention, a user equipment is provided. The user equipment according to the present invention includes: a receiving module and an updating module. The receiving module is configured to receive a notification sent by the mobility management unit, where the notification is used to indicate that the user equipment is currently accessed. The CSG is unavailable; the update module is configured to delete, according to the foregoing notification received by the receiving module, the identifier of the CSG identifier list of the user equipment corresponding to the CSG. According to still another aspect of the present invention, a home base station is provided.

The receiving module is configured to receive a handover request message sent by the mobility management unit, where the handover request message carries indication information indicating that the CSG currently accessed by the user equipment is unavailable, and the sending module is configured to receive, according to the receiving module, The foregoing switching request message sends a handover command to the user equipment, where the handover command carries the indication information. With the foregoing at least one aspect of the present invention, when the UE accesses the home base station corresponding to the CSG as a temporary user of the CSG, when the UE stays at the home base station (that is, the duration of the UE accessing the home base station) exceeds a preset. At the threshold, the mobility management unit notifies the UE that the currently accessed CSG is unavailable, so that the UE can save the allowed access to the CSG identifier list corresponding to the CSG, so that the UE and the network side allow access to the CSG identifier list. Synchronization avoids the waste of radio resources by the UE due to incorrect cell reselection, access 4 advertisement generation, invalid access attempts, etc., so that the user can decide whether to use the ordinary base station according to different situations, thereby improving the user.

In the embodiment of the present invention, when the mobility management unit determines that the camping time of the UE as the CSG temporary user exceeds a preset threshold (that is, the length of time that the temporary user is allowed to access), the mobility management unit notifies the UE of the currently accessed CSG. Not available, such that the UE can delete the identity of its saved CSG identification list that corresponds to the currently accessed CSG. The embodiments in the present application and the features in the embodiments may be combined with each other without conflict. The preferred embodiments of the present invention are described in the following with reference to the accompanying drawings, which are intended to illustrate and illustrate the invention. According to the embodiment of the present invention, a list update method is first provided, which is used to update the allowed access CSG identifier list of the UE when the UE is in a connected state. FIG. 5 is a flowchart of a method for updating a list according to an embodiment of the present invention. As shown in FIG. 5, the method for updating a list according to an embodiment of the present invention mainly includes the following steps (step S501 - step S503): Step S501: The mobile management unit determines The UE that is the temporary user of the CSG accesses the home base station of the CSG, and the duration of the stay of the UE is more than a preset threshold. In a specific implementation, after the UE that is the temporary CSG user accesses the home base station corresponding to the CSG, The mobile management unit detects whether the UE stays in the home base station (that is, the duration of the UE accessing the home base station). The preset threshold is the length of time that the CSG allows the temporary user to access. In a specific implementation process, a timer may be set for the UE, and the duration of the timer is a length of time for allowing the temporary user to access. When the UE accesses the home base station as a temporary user of the CSG, the timer is started. When the timer expires, the mobility management unit determines that the duration of the UE accessing the home base station times out. Step S503: The mobility management unit notifies the UE that the CSG corresponding to the currently accessed home base station is unavailable, so that the UE deletes the identifier corresponding to the CSG in the local allowed access CSG identifier list. In a specific implementation process, the mobility management unit notifies the UE that the CSG is unavailable, including but not limited to the following two methods:
1. 移动管理单元触发切换, 向家庭基站发送切换请求消息, 其中, 该切 换请求消息中携带有指示上述 CSG 不可用的指示信息; 家庭基站接收到该切 换请求后 , 向 UE发送切换命令, 该切换命令中携带有指示上述 CSG不可用的 指示信息; 1. The mobility management unit triggers a handover, and sends a handover request message to the home base station, where the handover request message carries indication information indicating that the CSG is unavailable; after receiving the handover request, the home base station sends a handover command to the UE, where The switching command carries indication information indicating that the CSG is unavailable;
2. 移动管理单元在触发切换前, 向 UE发送移动管理通知消息, 其中, 该移动管理通知消息中携带有指示上述 CSG不可用的指示信息。 UE在接收到移动管理单元发送的通知后, 将上述 CSG的标识从允许接 入 CSG标识列表中删除。 如果 UE当前接入的家庭基站为混合模式的家庭基站,即该家庭基站可以 采用闭合模式接入也可以采用开放模式接入,则移动管理单元在确定上述 CSG
不可用后, 还判断是否可以将 UE的接入模式从闭合模式改变为开放模式, 如 果可以, 则移动管理单元将 UE的接入模式从闭合模式改变为开放模式, 并通 知 UE当前的接入模式为开放模式。 2. Before the handover is triggered, the mobility management unit sends a mobility management notification message to the UE, where the mobility management notification message carries indication information indicating that the CSG is unavailable. After receiving the notification sent by the mobility management unit, the UE deletes the identifier of the CSG from the allowed access CSG identifier list. If the home base station currently accessed by the UE is a home mode in a mixed mode, that is, the home base station can adopt closed mode access or open mode access, the mobility management unit determines the CSG. After being unavailable, it is further determined whether the access mode of the UE can be changed from the closed mode to the open mode. If yes, the mobility management unit changes the access mode of the UE from the closed mode to the open mode, and notifies the UE of the current access. The mode is open mode.
UE在接收到移动管理单元的通知后 ,将上述 CSG的标识从允许接入 CSG 标识列表中删除, 同时, 还可以显示 ^!夺该 CSG标识删除的原因, 如果移动管 理单元通知 UE当前的接入模式为开放模式, 则 UE也将该信息显示给用户, 用户根据该信息可知由于当前接入的 CSG 不可用, 从而转换成开放模式, 如 果用户不希望采用该模式, 则可以手动发起切换, 切换到其它的家庭基站。 在本发明实施例中,根据接入方式不同, 上述移动管理单元可以为移动性 管理实体( Mobile Management Entity,筒称为 MME ),则上述家庭基站为 HeNB; 或者, 上述移动管理单元也可以为 GPRS月 务支持节点( Serving GPRS Support Node, 筒称为 SGSN ), 则上述家庭基站为 HNB。 才艮据本发明实施例提供的上述列表更新方法, 在 UE当前接入的 CSG不 可用时, UE可以删除其本地保存的允许接入 CSG标识列表, 从而使得 UE和 网络侧的允许接入 CSG标识列表保持同步。 为进一步理解本发明实施例提供的上述列表更新方法的具体实施过程中 , 以下以演进的无线接入网 (Evolved UTRAN, 筒称为 E-UTRAN ) 或 UTRAN 为例进行说明。 实施例一 在本实施例中 , 作为临时 CSG用户的 UE接入 HeNB, 当 UE接入 HeNB 的时长超时后, 通过无线资源控制 (Radio Resource Control, 筒称为 RRC ) 消 息通知 UE更新白表。 图 6示出了在本实施例中通过 RRC消息通知 UE更新白 表的流程, 如图 6所示, 主要包括以下步骤 (步骤 601 -步骤 617 ): 步骤 601 , UE当前所接入的 CSG所设定的定时器超时; 步骤 602 , 当前 MME通知 HeNB发起切换, 并且携带指示, 表明触发切 换的原因是, UE当前接入的 CSG已经不可用了; 步骤 603 , 当前 HeNB通过空口消息, 触发 UE上 4艮测量 4艮告, 该测量 4艮 告用于 HeNB决定切换到哪个小区 (即目标小区);

If the mobile management unit informs the UE that the current access mode is the open mode, the UE also displays the information to the user. According to the information, the user knows that the currently accessed CSG is unavailable, thereby converting In the open mode, if the user does not want to adopt this mode, the handover can be manually initiated to switch to other home base stations. In the embodiment of the present invention, the mobility management unit may be a mobility management entity (Mobile Management Entity, which is called MME), and the home base station is an HeNB, or the mobility management unit may be The GPRS monthly support node (Serving GPRS Support Node, called SGSN), the home base station is an HNB. According to the foregoing method for updating the list provided by the embodiment of the present invention, when the CSG currently accessed by the UE is unavailable, the UE may delete the locally allowed allowed access CSG identifier list, so that the UE and the network side allow access to the CSG identifier. The list stays in sync. To further understand the specific implementation process of the foregoing list update method provided by the embodiment of the present invention, the following describes an evolved radio access network (Evolved UTRAN, called E-UTRAN) or UTRAN as an example. In the first embodiment, the UE that is the temporary CSG user accesses the HeNB. After the time when the UE accesses the HeNB expires, the UE notifies the UE to update the whitelist by using a Radio Resource Control (RRC) message. FIG. 6 shows a flow of notifying the UE to update the whitelist by using the RRC message in the embodiment. As shown in FIG. 6, the method mainly includes the following steps (step 601 - step 617): Step 601: The CSG currently accessed by the UE The set timer expires; Step 602: The current MME notifies the HeNB to initiate the handover, and carries an indication that the reason for triggering the handover is that the CSG currently accessed by the UE is unavailable. Step 603: The current HeNB triggers the UE by using an air interface message. The top 4 measurement 4 report, the measurement 4 is used for the HeNB to decide which cell to switch to (ie, the target cell); The target cell may be another available HeNB under EUTRAN coverage or a common base station under EUTRAN coverage, or switched to a cell covered by UTRAN or GSM/EDGE Radio Access Network (GSM/EDGE Radio Access Network, called GERAN). . Step 604: The source HeNB initiates a handover request to the source MME, where the GF handover request carries the target cell identifier and a bearer list that needs to be forwarded. Step 605: The source MME selects the target MME or the SGSN according to the target cell identifier, and the source MME sends a forwarding relocation request to the target MME/SGSN, where the relocation request carries the international user of the UE. (International Mobile Subscriber Identification Number, called IMSI), target MME/SGSN identity, target cell identity, mobility management context and payload context, and whether to forward data flags directly. If the handover to the target cell is connected to the same MME, the target MME and the source MME in the process are the same entity. Step 606, the target MME/SGSN determines whether to re-select the security gateway (Security GateWay, the cartridge is called S-GW); if the S-GW changes, the target MME/SGSN sends a create bearer request to the target S-GW, where The tunnel endpoint identifier (the tunnel endpoint Identifier, the control plane address, and the data network gateway (the packet data network gateWay) is carried in the IMSI and the target MME/SGSN carrying the UE. And parameters such as TEID, and the target MME/SGSN will need to establish a bearer. If the handover does not require reselection of the S-GW, the target S-GW and the source S-GW in the flow are one entity, and step 606, step 607, and steps 610 and 611 need not be performed. Step 607: The target S-GW allocates a related resource to the bearer, and returns a create-load response to the target MME/SGSN, where the created bearer response carries the S-GW address and the TEID information. Step 608: If the target network is UTRAN The target SGSN sends a relocation request to the target radio network controller (Radio Network Controller, RNC) or the target HNB GW, requesting to establish a radio bearer, where the request carries the identifier of the UE, the cause value of the relocation, Relevant information required for authentication and integrity protection, and a list of radio bearers that need to be established. If the target network is EUTRAN, the target MME sends to the target eNB or HeNB The handover request is performed to request to establish a radio bearer, where the request carries the identifier of the UE, the cause value of the relocation, related information required for authentication and integrity protection, and a radio bearer list that needs to be established. The target MME/SGSN sends a relocation request to the target HeNB or the eNB or the RNC or HNB GW under the coverage of the UTRAN, requesting to establish a radio bearer, where the request carries the identifier of the UE, the cause value of the relocation, the authentication and integrity protection. Relevant information needed, as well as a list of wireless bearers that need to be established. Step 609: The target eNB or the HeNB or the UTRAN covers the RNC or the HNB GW to return a relocation request response to the target MME/SGSN, where the parameters carried in the relocation request response include the successfully established radio bearer list and the failed radio list. . Step 610: If the source HeNB decides to adopt the indirect forwarding mode, and the S-GW changes, the target MME/SGSN sends a create bearer request to the target S-GW. Step 611: The target S-GW returns a create bearer response to the target MME/SGSN. Step 612: The target MME/SGSN returns a forwarding relocation response to the source MME, where the parameters carried in the relocation response include the target MME/SGSN control plane tunnel end identifier and address, radio bearer setup information, and data forwarding tunnel end Identification and address. Step 613: In the indirect forwarding mode, the source MME sends a tunnel creation request to the source S-GW to create a tunnel for temporarily transmitting indirectly forwarded data. The tunnel needs to be released after the end of forwarding. Step 614: The source S-GW returns a create bearer response to the source MME. Step 615: The source MME sends a handover command to the source HeNB after completing the preparation phase of the handover. Step 616: The source HeNB notifies the UE to perform handover, where the carrying cause indication is that the currently accessed CSG is unavailable.

步骤 716 , 源 HNB GW通过源 HNB通知 UE执行切换 , 其中, 该通知 中携带有原因指示为当前 CSG不可用。 After receiving the information, the UE deletes the CSG id of the currently accessed HeNB from the list of allowed access CSG identifiers saved by the UE. Alternatively, this reason can be indicated to the user. Step 617: Perform a subsequent switching process. In the specific implementation process, the subsequent handover process can be implemented by using the prior art, and is not specifically mentioned. Those skilled in the art can disclose from existing ones. The specific execution process of the subsequent process is obtained in the data, and constitutes a complete process that can be implemented with the embodiment. In the embodiment, the UE that is the temporary CSG user accesses the HeNB in this embodiment. After the time when the UE accesses the HeNB expires, the UE notifies the UE to update the whitelist by using a Radio Resource Control (RRC) message. FIG. 7 shows a flow of notifying the UE to update the whitelist by using the RRC message in the embodiment. As shown in FIG. 7, the method mainly includes the following steps (step 701 - step 717): Step 701: The CSG currently accessed by the UE The set timer expires. Step 702: The current SGSN informs the HNB GW to initiate the handover, and carries an indication that the reason for triggering the handover is that the CSG currently accessed by the UE is unavailable. Step 703: The source HNB GW triggers the HNB to go to the UE to acquire the measurement 4 report, and is used to determine which cell to switch to. The target cell may be an available HeNB under EUTRAN coverage or a common base station under EUTRAN coverage, or may be handed over to other available home base stations or ordinary base stations under UTRAN/GERAN coverage. Step 704: The source HNB GW initiates a relocation request to the source SGSN, where the relocation request carries the target cell identifier and a bearer list that needs to perform data forwarding. Step 705: The source SGSN selects the target MME or the SGSN according to the target cell identifier, and the source SGSN sends a forwarding relocation request to the target MME/SGSN, where the parameters carried in the relocation request include the IMSI of the UE, the target MME/SGSN identifier. , target cell identity, mobility management context and bearer context, and whether to forward data flags directly. If the handover to the target cell is connected to the same SGSN, then the target SGSN and the source SGSN in the process are one entity. Step 706: The target MME/SGSN determines whether the S-GW is to be reselected. If the S-GW changes, the target MME/SGSN sends a create bearer request to the target S-GW, where the IMSI of the UE and the TEID of the target MME/SGSN are carried. Control plane address, P-GW address and TEID parameters. The target MME/SGSN will need to establish a bearer identity. If the handover does not require reselection of the S-GW, then the target S-GW and the source S-GW in the flow are one entity, and step 706, step 707, and steps 710 and 711 need not be performed. Step 707: The target S-GW allocates related resources for the bearer, and returns a create bearer response to the target MME/SGSN, where the S-GW address and the TEID information are carried. Step 708: If the target network is a UTRAN, the target SGSN sends a relocation request to the target RNC or the target HNB GW to request to establish a radio bearer, where the request carries the identifier of the UE, the cause value of the relocation, the authentication, and the integrity. Protection related information, a list of radio bearers that need to be established. If the target network is the EUTRAN, the target MME sends a handover request to the target eNB or the HeNB, requesting to establish a radio bearer, where the handover request carries the identifier of the UE, the cause value of the relocation, and the correlation required for the authentication and integrity protection. Information, a list of wireless bearers that need to be established. Step 709: The target eNB or the HeNB or the UTRAN covers the RNC or the HNB GW to return a relocation request response to the target MME/SGSN, where the parameters carried in the response include the successfully established radio bearer list and the failed radio list. Step 710: If the source HNB GW decides to adopt the indirect forwarding mode, and the S-GW changes, the target MME/SGSN sends a create bearer request to the target S-GW. Step 711: The target S-GW returns a create bearer response to the target MME/SGSN. Step 712: The target MME/SGSN returns a forwarding relocation response to the source SGSN, where the parameters carried in the response include the target MME/SGSN control plane tunnel end identifier and address, the radio bearer setup information, and the tunnel end identifier of the data forwarding. address. In step 713, the indirect forwarding mode is adopted, and the source SGSN sends a tunnel creation request to the source S-GW to create a tunnel for temporarily transmitting indirectly forwarded data. The tunnel needs to be released after the end of forwarding. Step 714: The source S-GW returns a create bearer response to the source SGSN. Step 715: The source SGSN sends a relocation command to the source HNB GW after completing the preparation phase of the handover. Step 716: The source HNB GW notifies the UE to perform the handover by using the source HNB, where the notification carries a reason indication that the current CSG is unavailable.
