Abstract

本发明涉及通信领域,特别涉及一种用户设备移动性管理方法、移动性管理设备及网络***,其中所述方法包括:当正在执行紧急业务且激活了空闲信令缩减机制的用户设备从第一网络接入切换为第二网络接入后,所述第二网络中的目标移动性管理设备判断不允许所述用户设备在所述第二网络中接入的目标小区中接入,则所述目标移动性管理设备触发释放所述用户设备的非紧急承载。本发明触发释放所述用户设备的非紧急承载,以此节省网络资源。

Description

用户设备移动性管理方法、 移动性管理设备及网络*** 技术领域
本发明涉及通信领域, 特别涉及一种用户设备移动性管理方法、 一种移动 性管理设备以及一种移动通讯网络***。 背景技术
为了限制用户设备(UE )接入特定的无线接入设备, 引入了封闭用户组 ( Closed Subscriber Group, CSG )机制。 一个 CSG区域包含一个或几个小区, 每个 CSG区域以一个 CSG标识符( CSG ID )来标识。 一个 CSG区域限定对 一组 UE允许接入, 对该组 UE之外的其它 UE限制接入。 对一个 UE而言, 允 许其接入的所有 CSG区域的 CSG ID构成允许 CSG列表( Allowed CSG List ), 也可称之为 CSG白名单 ( CSG White List )。
另外, 为了保证用户设备在一些特殊情况下仍能使用诸如报警业务和火警 业务等, 现有技术还引入了紧急业务机制。 在紧急业务机制下 , 在指定的场景 下 (比如, 用户在漫游禁止区域或者业务禁止区域) 只有紧急业务可以进行, 而其他的非紧急业务则不能进行。
另外, 为了减少网络信令的负荷, 3GPP还提出了空闲信令缩减(ISR, Idle mode signaling reduction )机制。 其主要目的是减少 UE在不同接入网络之间的 移动性管理流程。
但是,目前当正在执行紧急业务且激活了 ISR机制的 UE从当前网络接入设 备切换到不在用户的 Allowed CSG List中的小区所在目标接入设备之后, 除紧 急业务之外, UE的非紧急业务承载仍然被保留, 即 UE的非紧急承载仍然会被 继续用来进行业务,这样该 UE的非紧急承载会占用大量的网络资源, 这务必将 对其他 UE对网络资源的使用造成不利影响以及造成网络资源的大量浪费。 发明内容
鉴于此, 本发明提供一种用户设备移动性管理方法、 一种移动性管理设备 以及一种移动通讯网络***, 可触发释放所述用户设备的非紧急承载, 以此节 省网络资源。 具体的, 本发明实施例提供的一种用户设备移动性管理方法, 包括: 当正在执行紧急业务且激活了空闲信令缩减机制的用户设备从第一网络接 入切换为第二网络接入后, 所述第二网络中的目标移动性管理设备判断不允许 所述用户设备在所述第二网络中接入的目标小区中接入, 则所述目标移动性管 理设备触发释放所述用户设备的非紧急承载。
相应的, 本发明实施例提供的一种移动性管理设备, 位于第二网络中, 其 包括:

59 , 目标移动性管理设备向源移动性管理设备发送前向切换完成消息 ( Forward Relocation Complete )。
510, 目标移动性管理设备判断用户激活了 ISR且存在紧急业务, 则根据本 地保存的用户 CSG签约信息判断不允许用户设备在当前 CSG小区接入,则目标 移动性管理设备向服务网关发送删除承载消息(Delete Bearer Request ), 删除承 载消息中携带需删除的非紧急承载的标识。
511 , 服务网关向分组数据网络网关发送删除承载消息 (Delete Bearer Request ) , 删除承载消息中携带需删除的非紧急承载的标识。
512, 分组数据网络网关删除所述非紧急承载的标识所指示的承载, 并向所 述服务网关发送删除 载响应消息 ( Delete Bearer Response )。
513 ,服务网关向目标移动性管理设备发送删除承载响应消息( Delete Bearer Response λ
514, 源移动性管理设备向目标移动性管理设备发送前向切换完成确认消息 ( Forward Relocation Complete )。
