Description

一种实现重定位的方法及系统 技术领域
本发明涉及宽带码分多址接入技术, 尤指一种用户设备(UE, User Equipment )处于专用信道连接状态下,在不同无线网络控制器( RNC, Radio Network Controller )之间移动时, 实现重定位的方法及系统。 背景技术
宽带码分多址接入 ( WCDMA , Wide band Code Division Multiple Access )是一种第三代无线通信系统,其空中接口利用码分多工复用方法进 行宽带扩频无线通信, 向上层提供数据传输服务。
在早期第三代合作伙伴计划( 3GPP , 3rd Generation Partnership Project ) 协议版本中,由于 UE的真实数据传输状态对无线网络控制器(RNC, Radio Network Controller ) 而言是不可见的。 因此, 对于分组业务(PS, Packet Service )来说, RNC只能使用一般集合的定时器来为 UE分配无线承载、 以及确定状态迁移的时间。这种通过网络侧来为 UE配置不活跃检测定时器 的方式, 使得很多 UE的电池效率实际上是很低的。 为此, 3GPP在版本 8 ( R8, Release 8 )中引入了快速休眠, 由 UE主动向网络侧指示其状态。 具 体做法可以是: UE 在信令连接释放指示 (SIGNALLING CONNECTION RELEASE INDICATION ) 消息中, 通过设置信令连接释放指示原因 ( Signaling Connection Release Indication Cause )信元的取值为 UE请求 PS 数据会话中止( UE Requested PS Data session end ), 向网络侧指明 UE已决 定结束一个已激活的 PS数据传输; RNC收到该指示后, 可决定是否触发 UE迁移到寻呼信道(PCH, Paging Channel )或者空闲 (IDLE )状态, 从 而使 UE减少不必要的电源消耗,进入更优电池效率的状态。在快速休眠功 能中, 必须启动 Τ323定时器: 当 UE检测到在一段时间内已没有 PS数据 时, 启动 Τ323定时器, 同时向 RNC发送 UE Requested PS Data session end 指示,在 T323定时器运行期间, UE禁止向 RNC发送 UE Requested PS Data session end指示, 直至 T323超时。 快速休眠功能可以广泛应用于网络中, 以提高 UE设备的电池使用效率, 增强用户体验。
如果 UE处于专用信道连接状态, 在不同 RNC之间移动时, 会用到多 于一个 RNC的资源, 不同的 RNC此时充当着不同的角色。 服务无线网络 控制器( SRNC, Serving Radio Network Controller ) 为保持该 UE与核心网 的接口连接的 RNC, 用于负责核心网和 UE之间的数据传送和与核心网的 接口信令的转送和接收, 进行无线资源控制, 对空中接口的数据进行层二 的处理, 并执行基本无线资源管理操作。 漂移无线网络控制器 (DRNC, Drift Radio Network Controller )是服务 RNC以外的其他 RNC, 漂移 RNC 控制该 UE使用的小区。 当 UE逐渐向漂移 RNC移动时, 会触发 UE相关 重定位过程, 服务 RNC决策执行 UE相关重定位过程, 服务 RNC通过核 心网 (CN, Core Network )向漂移 RNC获取到发给 UE的切换命令, 然后 向 UE发送该切换命令, UE再根据该切换命令完成 UE相关重定位过程。
在专用信道连接状态下, UE在 RNC间移动时, 在其移动到漂移 RNC 后, 在执行 UE相关重定位过程时, 无法通过服务 RNC发送的切换命令来 获取漂移 RNC的 T323定时器, 这样, 即便漂移 RNC支持快速休眠, UE 在重定位后也无法启动快速休眠功能 , 使得快速休眠功能失效。 发明内容
