Description

分流判决方法、 高移动性状态识别方法及设备 技术领域
本发明实施例涉及通信技术， 尤其涉及一种分流判决方法、 高移动性 状态识别方法及设备。 背景技术
传统 3GPP架构下，无线接入网络（Radio Access Network,简称 RAN) 通过 IuPS接口与分组交换 （Packet Switched, 简称 PS ) 域核心网相连。 在 PS业务中大部分为 Internet业务， PS核心网中网关 GPRS支持节点 ( Gateway GPRS Support Node ， 简称 GGSN) 或服务 GPRS支持节点 ( Serving GPRS Support Node, SGSN) 需要将 PS业务路由至 Internet服 务提供商的服务器。 随着数据业务的高速增长， 数据业务会占用核心网的 大量传输带宽， 需通过扩容和升级核心网来增加传输带宽， 但核心网扩容 和升级成本较高。 对于无线运营商来说， 作为数据业务主体的 Mobile Internet业务 （例如， Web应用、 文件传输或 P2P) 属于低价值业务， 增 量不增收。 因此， 可通过 RAN层面将 RAN与 PS域核心网的数据流直接 分流到 Internet, 从而节约 RAN与 PS域核心网的传输成本和网络升级成 本。 PS数据流通过 RAN侧的 Offload Gi接口分流到 Internet后， PS数据 业务的锚点由 GGSN或 SGSN下移到 RAN侧的网络侧实体是无线网络控 制器 (Radio Network Controller, 简称 RNC) 或基站 (NodeB ) 。
RAN侧网络实体支持 Internet 分流功能时， 可通过一系列的分流策 略确定哪些数据流可以分流到 Offload Gi接口。 分流策略一般基于用户类 型及业务类型等定义， 只有符合分流策略的数据流才会被分流到 Offload Gi 接口。 现有技术的分流策略中， 只要满足相应业务分流策略和用户分 流策略， 高速移动中的终端的数据流也会通过 Offload Gi口进行分流。 然 而， 过于频繁的跨 RAN实体切换及相应的节点间的转发传输已带来额外 的处理开销和传输开销，而终端高速移动时进行分流会带来更加额外的处 理开销和传输开销， 从而增加了中断业务的风险。 发明内容
本发明实施例提供一种分流判决方法、 高移动性状态识别方法及设 备， 用以解决现有的分流方法业务中断风险较高的缺陷。

为使本发明实施例的目的、 技术方案和优点更加清楚， 下面将结合本 发明实施例中的附图， 对本发明实施例中的技术方案进行清楚、 完整地描 述， 显然，所描述的实施例是本发明一部分实施例， 而不是全部的实施例。 基于本发明中的实施例， 本领域普通技术人员在没有付出创造性劳动前提 下所获得的所有其他实施例， 都属于本发明保护的范围。
本发明实施例适应于 3G网络和 4G网络以及更高级的网络制式的网 络中数据业务分流场景。其中， 3G网络可以是通用移动通信***（Universal Mobile Telecommunications System, 简称 UMTS ) 网络、 码分多址接入 ( Code Division Multiple Access ， 简称 CDMA) 2000网络、 宽带码分多 址接入 （Wideband Code Division Multiple Access, 简称 WCDMA) 和时 分同步的码分多址接入 ( Time Division― Synchronous Code Division Multiple Access,简称 TD-SCDMA)网络。 3G网络中无线接入网络（Radio Access Network,简称 RAN)侧实体可以是无线网络控制器（Radio Network Controller, 简称 RNC ) 或基站 （NodeB , 核心网络侧实体可以是 xGSN, 例如网关 GPRS支持节点 （Gateway GPRS Support Node, 简称 GGSN) 或 服务 GPRS支持节点 ( Serving GPRS Support Node ， 简称 SGSN) 。其中， 4G网络可为长期演进 （Long Term Evolution, 简称 LTE) 网络或 LTE高 级 （LTE Advanced) 网络。 LTE或 LTE高级网络中， 无线网络接入侧实 体可以是演进基站（evolved NodeB , 简称 eNB ) 。 其中， 数据业务可以是 分组域交换（Packet Switched, 简称 PS )业务， 例如： 语音业务， 流业务、 背景类业务、 无线应用协议 （Wireless Application Protocol, 简称 WAP) 业务或多媒体消息服务 （Multimedia Message Service, 简称 MMS ) 业务。
图 1A为本发明实施例提供的一种分流判决方法流程图。 本实施例中 RAN侧设备， 在 3G网络中可以为 RNC, 在 4G网络中为演进基站。 如图 1A所示， 包括：
步骤 11 : 在终端发起数据业务时， RAN侧设备接收来自核心网络侧 实体的无线接入承载分配请求。
在 3G 网络中， 无线接入承载分配请求可以是 RAB ( Radio Access Bearer ， 无线接入承载） Assignment Request消息。 终端发起数据业务时，
RAN侧设备，根据核心网络侧实体的无线接入承载分配请求，在接入网与 核心网之间为终端建立无线接入承载。无线接入承载分配请求包括有终端 的用户类型信息和业务类型信息。 例如， 用户类型包括数据卡用户、 智能 终端用户和普通终端用户等， 业务类型包括语音业务， 流业务、 背景类业 务、 WAP业务和 MMS业务。
步骤 12: RAN侧设备根据无线接入承载分配请求在接入网与核心网 之间为终端建立无线接入承载过程中， 根据基于业务的分流策略和基于用 户的分流策略以及终端的移动性， 判断是否对终端发起的数据流进行分 流。
步骤 13 : 在终端对应的无线接入承载符合基于业务的分流策略和 /或 基于用户的分流策略时，若终端没有处于高移动状态， RAN侧设备确定对 终端发起的数据流进行分流。
RAN侧设备可先根据无线接入承载分配请求携带的业务类型信息，例 如终端的 Traffic Class (业务类别） ， 确定终端对应的无线接入承载是否 与基于业务的分流策略相匹配。在终端对应的无线接入承载与基于业务的 分流策略相匹配时， 再根据无线接入承载分配请求携带的终端的用户类型 信息， 例如终端的 IMEI (国际移动设备标识） 、 IMSI (国际移动台标识 码） 、 ARP (地址解析协议） 、 APN (接入点名称）和 Cell ID (小区标识） 中一项或多项组合， 确定终端对应的无线接入承载是否与基于用户的分流 策略相匹配。 在终端对应的无线接入承载与基于用户的分流策略相匹配 时， RAN侧设备再进一步根据终端的移动性，确定是否对终端发起的数据 流进行 Internet分流。 在终端没有处于高移动性状态时， 确定对终端发起 的数据流进行分流， 将终端发起的数据流直接分流到 Internet网， 而不需 要经过核心网的传输。 在终端处于高移动性状态时， 为节省处理开销和传 输开销， 确定不对终端发起的数据流进行分流， 通过核心网将终端发起的 数据流传输到 Internet网。
另外， RAN侧设备也可在确定终端对应的无线接入承载与基于业务的 分流策略相匹配后， 或在确定终端对应的无线接入承载与基于用户的分流 策略相匹配后， 根据终端的移动性， 确定是否对终端发起的数据流进行 Internet分流。
对于终端的移动性的测量， 可由 RAN侧设备在接收到无线接入承载 分配请求后， 向终端发送包括移动性识别参数的***广播消息， 由终端根 据移动性识别参数识别自身是否处于高移动性状态， 并通过后续的无线资 源控制 （Radio Resource Control, 简称 RRC) 信令上报给 RAN侧设备。 另外， 也可由 RAN侧设备根据移动性识别参数识别终端是否处于高移动 性状态。
图 1B为本发明实施例提供的一种 RAN侧分流高移动性场景示意图。 如图 1B所示， RAN侧的 RNC通过 IuPS接口与核心网侧的 xGSN相连， RNC通过 lub接口与 NodeB相连， 各 RNC之间通过 lur接口相连， 互联 网服务提供商 （Internet Service Provider, 简称 ISP)通过 Gi接口与 xGSN 相连。 在 RAN为实体终端建立无线接入承载过程中， 终端 （UE) 在以下 RAN实体间： NodeBl、 NodeB2、 NodeB3和 NodeB4， 进行高移动性切换。 根据图 1A对应实施例提供的方法， RNC在为终端建立无线接入承载过程 中对终端的数据流进行分流判决， 即使确定终端对应的无线接入承载符合 基于业务的分流策略和基于用户的分流策略， 由于终端处于高移动性状 态， RAN侧设备也不会将终端的数据流通过 Offload Gi接口分流到 Internet 网， 而是通过核心网将终端发起的数据流传输到 Internet网。 本实施例提供的分流判决方法， 在为终端建立无线接入承载过程中， 基于用户和基于业务对终端发起的数据流进行分流判决后， 增加了基于终 端移动性的分流判决。 RAN侧设备只对处于高速移动性状态的终端进行分 流。对于处于高移动性状态的终端， RAN侧设备不对终端发起的数据流进 行分流， 避免终端高速移动时因分流带来的处理开销和传输开销， 降低了 分流过程中业务被中断的风险， 提高了***效率。
图 2为本发明实施例提供的一种高移动性状态识别方法流程图。本实 施例说明终端如何根据移动性识别参数识别自身是否处于高移动性状态。 本实施例以 3G网络中的 RNC和 3G网络中状态为 Idle、 URA PCH和 CELL— PCH 的终端为例进行说明。 本实施例适用于本地流量卸载 （Local Breakout, 简称 LBO) 相关的高移动状态识别。 如图 2所示， 本实施例包 括：
步骤 21 :终端接收 RNC发送的包括移动性识别参数的***广播消息。 处于 Idle、 URA— PCH和 CELL— PCH状态的终端， 还没有和 RAN建 立无线资源控制 （Radio Resource Control, 简称 RRC) 连接， 此时终端无 业务或者业务处于暂时挂起状态， 终端通过公共信道监听广播消息。 当有 业务需求时终端重新发起 RRC连接并建立专有信道通信。
在 RNC接收到无线接入承载分配请求之前， 通过广播消息向终端发 送包括移动性识别参数的***广播消息。 RNC发送的移动性识别参数可包 括小区重选最大识别时间 LBO— Tldmax、 小区重选最大数目 LBO— Nld和 恢复慢速移动前的额外时间 LBO— TldmaxHyst。 如果终端在***广播消息 中接收到上述移动性识别参数， 则执行与 LBO相关的高移动性状态识别。
步骤 22: 终端根据移动性识别参数和小区重选次数， 确定终端是否处 于高移动性状态。
在小区重选最大识别时间 LBO— Tldmax内，终端的小区重选次数大于 小区重选最大数目 LBO— Nld， 确定终端处于 LBO相关的高移动状态。
确定终端处于高移动状态后， 终端继续在下一个小区重选最大识别时 间 LBO— Tldmax 内， 判断小区重选次数是否小于小区重选最大数目 LBO Nld。 如果大于， 确定终端处于高移动性状态； 如果小于， 进一步判 断在下一个小区重选最大识别时间 LBO— Tldmax 之后的恢复慢速移动前 的额外时间 LBO— TldmaxHyst内，终端的小区重选次数累计是否小于小区 重选最大数目 LBO— Nld。 如果小于， 确定终端没有处于 LBO相关的高移 动状态； 如果大于， 确定终端处于高移动性状态。
步骤 23 : 在确定终端处于高移动性状态时， 终端生成用于表示终端处 于高移动性状态的高移动性状态标志， 并通过无线资源控制信令发送给 如果终端处于 LBO相关的高移动性状态， 终端生成高移动性状态标 志， 并将 LBO相关的高移动性状态标志携带在后续发起的 RRC连接发送 给 RNC。 携带 LBO相关的高移动性状态标志的 RRC信令包括 RRC连接 请求（RRC CONNECTION REQUEST) ， 小区更新（CELL UPDATE) 或 者 UTRAN注册区更新 （URA UPDATE) 等。 接收到包含 LBO相关的高 移动性状态标志的 RRC信令时， RNC确定 UE当前处于 LBO相关的高移 动性状态。 如果 RNC接收到的 RRC信令中没有包括 LBO相关的高移动 性状态标志， 确定当前终端不支持 LBO相关的高移动性识别或者终端当 前不处于 LBO相关的高移动性状态。
处于 Idle、 URA PCH和 CELL— PCH状态的终端还没有和 RAN建立 RRC连接， 通过公共信道监听广播消息。 RNC通过广播消息向终端发送 移动性识别参数， 终端根据移动性识别参数识别到终端处于高移动性状态 时， 通过后续建立的 RRC信令， 将高移动性状态标志上报给 RNC。
可以理解的是， 本发明实施例中终端和 RNC之间的交互， 实际过程 中需要通过基站的转发。 另外， 随着网络的演进， 上述 RNC所实现的功 會^ 也可能由 3G网络中的基站所实现。
图 3为本发明实施例提供的另一种高移动性状态识别方法流程图。本 实施例提供的高移动性状态识别方法可适用于 3G 网络中处于 CELL— FACH状态和 CELL— DCH状态的终端。 处于 CELL— FACH状态和 CELL DCH状态的终端已和 RAN建立 RRC连接， 此状态下的终端通过 专有信道与 RAN进行无线业务， 不监听公共信道。 如图 3所示， 本实施 例包括： 步骤 31 : 在 Id事件最大识别时间内， 终端通过测量报告上报的 Id 事件次数大于 Id事件最大数目， RNC确定终端处于高移动状态。
在 RNC为终端建立无线接入承载后，终端根据 RNC下发的测量通知， 在 Id事件次数达到预设值时向 RNC上报测量报告。 RNC通过配置的以下 参数: Id事件最大识别时间、 Id事件最大数目和恢复慢速移动前的额外 时间， 对终端的移动性进行识别。 Id事件是最佳小区变化事件， 某个导频 测量值比激活集内最佳小区测量值强时， 激活集中当前为终端服务的最佳 小区变成了另外一个小区， 终端上报 Id事件。
步骤 32: 确定终端处于高移动状态后， 在下一个 Id事件最大识别时 间内， 终端上报的 Id事件次数小于 Id事件最大数目， 且在下一个 Id事 件最大识别时间之后的恢复慢速移动前的额外时间内， 终端上报的 Id事 件次数累计小于 Id事件最大数目， RNC确定终端没有处于高移动状态。
RNC确定终端处于高移动状态后，继续根据终端通过测量报告上报的 Id事件次数确定终端的移动性时， 先判断在下一个 Id事件最大识别时间 内， 终端上报的 Id事件次数是否小于 Id事件最大数目。 如果大于， 确定 终端仍处于高移动状态； 如果小于， 进一步判断在下一个 Id事件最大识 别时间之后的恢复慢速移动前的额外时间内， 终端上报的 Id事件次数累 计是否小于 Id事件最大数目。 如果小于， 确定终端不处于高移动状态； 如果大于， 确定终端仍处于高移动状态。
