Description

业务建立方法、 系统、 无线网络控制器及用户终端 技术领域
本发明涉及通信领域， 尤其涉及业务建立方法、 系统、 无线网络控制器及 用户终端。 背景技术
现有的移动通信网络中， UE ( User Equipment, 用户设备 )有两种运行模 式， 分别为空闲模式和连接模式。 其中， 当 UE处于空闲模式时， 该 UE待机， 此时 UE没有业务， 与网络侧之间没有连接； 当 UE处于连接模式时， UE完成 RRC ( Radio Resource Control, 无线资源控制）连接， 此时包括四种信道状态， 分别为 Cell-DCH ( Dedicated Channel,专用信道）、 Cell-FACH ( Forward Access Channel,前向接入信道）时、 Cell-PCH( Paging Channel,寻呼信道 URA-PCH。
随着智能终端的沖击， 通信网络中会产生大量的信令。 当 UE无数据传输 时， 可以从连接模式迁移到空闲模式， 此时当 UE需要发起新业务时， 就需要 从空闲状态迁移到连接状态， 上述迁移过程会生成大量的信令，从而对通信网 络造成沖击。 因此， 现有技术中可以在 UE无数据传输时， 迁移到 Cell-PCH状 态， 从而在 UE需要发起新业务时， 从 Cell-PCH状态迁移到 Cell-DCH状态， 由 于 Cell-PCH状态和 Cell-DCH状态都属于连接模式，因此其迁移过程可以减少信 令的产生和对通信网络的沖击。
发明人在对现有技术的研究过程中发现， 当 UE侧在 Cell-PCH状态下发起 主叫或被叫 CS业务时， 需要从 Cell-PCH状态迁移到 Cell-DCH状态， 上述迁移 过程是从小区更新 ( Cell update )到无线 载建立 （ RB SETUP COMPLETE ) 的过程，整个过程的时延称为 P2D ( PCH to DCH )。现有技术中，在从 Cell-PCH 状态迁移到 Cell-DCH状态时， 首先需要从 Cell-PCH状态迁移到 Cell-FACH状 态， 再从 Cell-FACH状态迁移到 Cell-DCH状态， 整个迁移过程繁瑣， 增加了业 务建立的时间。 发明内容 本发明的实施实施例提供了业务建立方法、 系统、无线网络控制器及用户 终端， 以解决现有业务建立过程繁瑣， 建立时间较长的问题。

由上述实施例可知， 其与现有技术的不同在于， 无需在建立业务时， 进行 多个状态之间的迁移，而是通过在小区更新请求消息中携带支持无线承载建立 的指示， 使得 UE可以在实现小区更新的流程中一步到位建立业务， 由此降低 了状态之间的迁移繁瑣程度， 减少了业务建立时间， 降低了 P2D时延。 参见图 2, 为本申请业务建立方法的第二实施例流程图， 该实施例示出了 RNC通过发送小区更新证实消息指示 UE建立业务的过程：
步骤 201: UE向 RNC发送小区更新请求消息， 该小区更新请求消息中 携带无线承载建立指示。
UE 处于连接模式时， 包括四种信道状态， 分别为 Cell-DCH 状态、 Cell-FACH状态、 Cell-PCH状态和 URA-PCH状态。其中，当 UE进入 Cell-PCH 状态时， 如果需要发起 CS ( circuit switching, 电路交换）主被叫， 则会触发 小区更新过程， 本申请实施例就是在小区更新过程中一步到位从 Cell-PCH状 态迁移到 Cell-DCH状态， 实现业务建立。
在小区更新过程中， UE向 RNC发送小区更新请求消息 （ Cell Update ), 该小区更新请求消息中携带有无线承载建立指示（ RB SETUP Indicator ), 该无 线承载建立指示为小区更新请求消息中新增的信元，如果该信元的值为 "true" , 则表示支持在 d、区更新过程中进行业务建立。
步骤 202: RNC判断该指示为支持无线承载建立时， 向基站发送无线链 路建立请求消息。
RNC接收到小区更新消息后， 查看该消息中是否携带无线承载建立指示， 如果携带， 判断该指示的值是否为 "true" , 如果为 true, 则发起业务建立流程， 向基站发送无线链路建立请求消息 （ Rl Setup Requset )。
步骤 203: 基站在无线链路建立完成后， 向 RNC返回无线链路建立成功 的响应消息。
当基站完成无线链路建立后， 向 RNC返回无线链路建立成功的响应消息 ( Rl Setup Response )。无线链路是承载无线业务的基础，是业务建立的一部分， 无线链路的建立就包括从发送 Rl Setup Requset到接收了 Rl Setup Response的 过程。
步骤 204: RNC接收到无线链路建立成功的响应后， 向 UE发送小区更 新证实消息， 该小区更新证实消息中携带有业务建立参数。 当无线链路建立完成后， RNC向 UE发送小区更新证实消息（Cell Update Confirm ), 该小区更新证实消息中携带有业务建立参数， UE、 RNC及基站之 间可以根据这些参数建立业务。
这些业务建立参数具体可以包括：用于提供非接入层传输用户面数据的承 载的 RAB ( Radio Access Bearer, 无线接入 载 )参数； 用于提供 UE和 RNC 之间用户数据传送的承载的 RB ( Radio Bearer, 无线承载）参数。
步骤 205: UE根据小区更新证实消息与基站进行上行同步。
步骤 206:上行同步完成后，基站向 RNC发送无线链路恢复指示消息（ RL RESTORE„
步骤 207: UE向 RNC回复无线^载建立完成消息， 该无线 载建立完成 消息用于指示 UE与基站之间完成业务建立。
由上述实施例可知， 其与现有技术的不同在于， 无需在建立业务时， 进行 多个状态之间的迁移，而是通过在小区更新请求消息中携带支持无线承载建立 的指示， 使得 UE可以在实现小区更新的流程中一步到位建立业务， 由此降低 了状态之间的迁移繁瑣程度， 减少了业务建立时间， 降低了 P2D时延。 参见图 3 , 为本申请业务建立方法的第三实施例流程图， 该实施例示出了 RNC通过发送无线承载建立请求消息指示 UE建立业务的过程：
步骤 301: UE向 RNC发送小区更新请求消息， 该小区更新请求消息中 携带无线承载建立指示。
UE 处于连接模式时， 包括四种信道状态， 分别为 Cell-DCH 状态、 Cell-FACH状态、 Cell-PCH状态和 URA-PCH状态。其中，当 UE进入 Cell-PCH 状态时， 如果需要发起 CS ( circuit switching, 电路交换）主被叫， 则会触发 小区更新过程， 本申请实施例就是在小区更新过程中一步到位从 Cell-PCH状 态迁移到 Cell-DCH状态， 实现业务建立。
在小区更新过程中， UE向 RNC发送小区更新请求消息 （ Cell Update ), 该小区更新请求消息中携带有无线承载建立指示（ RB SETUP Indicator ), 该无 线承载建立指示为小区更新请求消息中新增的信元，如果该信元的值为 "true" , 则表示支持在 d、区更新过程中进行业务建立。 步骤 302: RNC判断该指示为支持无线承载建立时， 向基站发送无线链 路建立请求消息。
RNC接收到小区更新消息后， 查看该消息中是否携带无线承载建立指示， 如果携带， 判断该指示的值是否为 "true" , 如果为 true, 则发起业务建立流程， 向基站发送无线链路建立请求消息 （ Rl Setup Requset )。
步骤 303: 基站在无线链路建立完成后， 向 RNC返回无线链路建立成功 的响应消息。
当基站完成无线链路建立后， 向 RNC返回无线链路建立成功的响应消息 ( Rl Setup Response )。无线链路是承载无线业务的基础，是业务建立的一部分， 无线链路的建立就包括从发送 Rl Setup Requset到接收了 Rl Setup Response的 过程。
步骤 304: RNC接收到无线链路建立成功的响应后， 向 UE发送无线承 载建立请求消息， 该无线承载建立请求消息中携带有指示建立业务的信息。
当无线链路建立完成后， RNC 向 UE发送无线承载建立请求消息 （RB SETUP ), 该无线承载建立请求消息中携带有指示建立业务的信息。
这些业务建立参数具体可以包括：用于提供非接入层传输用户面数据的承 载的 RAB ( Radio Access Bearer, 无线接入 载 )参数； 用于提供 UE和 RNC 之间用户数据传送的承载的 RB ( Radio Bearer, 无线承载）参数。
步骤 305: UE根据无线承载建立请求消息与基站进行上行同步。
步骤 306:上行同步完成后，基站向 RNC发送无线链路恢复指示消息（ RL
RESTORE )。
步骤 307: UE向 RNC回复无线^载建立完成消息， 该无线 载建立完成 消息用于指示 UE与基站之间完成业务建立。
由上述实施例可知， 其与现有技术的不同在于， 无需在建立业务时， 进行 多个状态之间的迁移，而是通过在小区更新请求消息中携带支持无线承载建立 的指示， 使得 UE可以在实现小区更新的流程中一步到位建立业务， 由此降低 了状态之间的迁移繁瑣程度， 减少了业务建立时间， 降低了 P2D时延。 与本发明业务建立方法的实施例相对应， 本发明还提供业务建立系统、无 线网络控制器和用户终端的实施例。
