Description

一种实现小区更新或 URA更新的方法及系统
技术领域
本发明涉及宽带码分多址接入 ( WCDMA, Wide band Code Division Multiple Access )技术, 尤指一种 UE处于公共信道连接状态下, 在小区或者 RNC间移动时, 实现小区更新或通用地面无线接入网注册区(URA )更新的 方法及系统。
背景技术
WCDMA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, 由于移动终端 (UE, User Equipment ) 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 )业务来说, 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 为终端配置不活跃检测定时器的方式, 使得很多终端设备的电池效率实际上 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。 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 T323定时器: 当 UE检测到在一段时间内已没有 PS 数据时,启动 T323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 提高终端设备的电池使用效率, 增强用户体验。
当 UE处于公共信道连接状态时, 会由于移动而触发小区更新 (CELL UPDATE )过程或者 URA更新 ( URA UPDATE )过程 , 其中, URA为通用 地面无线接入网注册区 (UTRAN注册区, Universal Terrestrial Radio Access Network Registration Area ) , 向网络侧指示其最新所处的 CELL或者 URA。
RNC收到 UPDATE消息后, 会向 UE返回小区更新确认 ( CELL UPDATE CONFIRM )或者 URA更新确认( URA UPDATE CONFIRM ) 消息。
在公共信道连接状态下, UE在小区或者 RNC间移动时, 在其移动到目 标小区后 , 无法通过 CELL UPDATE或者 URA UPDATE过程来获取目标小 区的 T323定时器, 这样, 即便目标小区支持快速休眠机制, UE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
有鉴于此,本发明的主要目的在于提供一种实现小区更新或 URA更新的 方法及系统, 能够使得 UE在公共信道连接态下, 通过小区 (或者 URA ) 更 新过程, 获得 T323定时器, 从而保证快速休眠功能的有效性。

图 3为本发明应用实例一的实现小区更新或 URA更新的方法的流程示意 图, 在该应用实例中, 假设终端处于公共信道连接状态, 从小区 1移动到小 区 2; 小区 2不支持快速休眠处理机制, 小区 2归属的 RNC为 RNC2。 如图 3所示, 包括以下步骤:
步骤 300: 终端从小区 1移动到小区 2, 在小区 2中向 RNC2发送 CELL UPDATE消息或 URA UPDATE消息, 请求更新至小区 2。
步骤 301: RNC2接收到来自终端的 CELL UPDATE消息或 URA UPDATE 消息, 获知终端请求更新至小区 2。 由于小区 2不支持快速休眠的处理机制, 则 RNC2在小区 (或 URA ) 更新证实消息中不携带 T323信元。 RNC2在小 区 2中向终端回复小区 (或 URA ) 更新证实消息。
步骤 302: 终端在小区 2中接收小区 (或 URA ) 更新证实消息, 由于该 消息中未携带 T323信元,则确定 RNC2不支持快速休眠的处理机制。终端保 存不支持快速休眠的处理机制的信息。
图 4为本发明应用实例二的实现小区更新或 URA更新的方法的流程示意 图, 应用实例二中, 假设终端处于公共信道连接状态, 从小区 1移动到小区 2; 小区 2支持快速休眠处理机制, 小区 2归属的 RNC为 RNC2。 如图 4所 示, 包括以下步骤:
步骤 400: 终端从小区 1移动到小区 2, 在小区 2中向 RNC2发送 CELL UPDATE消息或 URA UPDATE消息 , 请求更新至小区 2。
步骤 401: RNC2接收到来自终端的 CELL UPDATE消息或 URA UPDATE 消息, 获知终端请求更新至小区 2。 由于小区 2支持快速休眠的处理机制, 则 RNC2在小区(或 URA )更新证实消息中携带 T323信元, 并将 T323信元 设置为小区 2中使用 T323的具体时长。 RNC2在小区 2中向终端回复小区(或 URA ) 更新证实消息。
步骤 402: 终端在小区 2中接收小区 (或 URA ) 更新证实消息, 由于该 消息中携带有 T323信元,则确定 RNC2支持快速休眠的处理机制。终端保存 支持快速休眠的处理机制的信息以及 T323定时器的具体时长。
以上所述, 仅为本发明的较佳实施例而已, 并非用于限定本发明的保护 范围, 凡在本发明的精神和原则之内所作的任何修改、 等同替换和改进等, 均应包含在本发明的保护范围之内。
工业实用性 通过本发明实施例的方法和系统,处于公共信道连接状态下的 UE,在小 区或 RNC间移动时, 在该 UE移动到目标小区后, 通过 CELL UPDATE或 URA UPDATE过程获得了目标小区的 T323定时器, 保证了快速休眠功能的 有效性。 因此本发明具有很强的工业实用性。
