Description

一种小区切换的方法、 装置及系统 技术领域
本发明涉及通信技术领域,尤其涉及一种小区切换的方法、装置及系统。 背景技术
随着移动通信技术的发展, 用户需求越来越高。 通过在现有的宏网中引 入微小区(英文: Small Cell), 可以成倍地提高系统小区数量; 在微小区吞吐 率保持不变的情况下, 可以成倍(甚至成成十倍)地提高系统容量。 其中微 小区对应的微小区基站可以是家庭基站, 或称微微基站(英文: Pico )、 微基 站(英文: Micro )、 微基站 (英文: Low Power Node, 简称: LPN)。 下面统一 使用微小区基站来表述这类基站, 而其网关, 比如家庭基站的网关等, 统称 为基站网关。
如图 1所示为现有技术中微小区与宏小区的部署结构图, 在图 1 中微小 区 Pico 和宏小区 NodeB 共用一个无线网络控制器 (英文: Radio Network Controller, 简称: RNC ), 此时的微小区基站具有类似宏小区基站的功能, 微 小区基站直接通过逻辑接口 Iub与 RNC进行交互。
微小区以及宏小区可以同频布网也可以异频布网, 当微小区与宏小区同 频布网时, 由于用户设备(英文: User Equipment, 简称: UE )在微小区上行 链路路损较小, 因此功控过程会逐渐降低 UE的上行发射功率,这样将导致宏 基站无法接收 UE的上行信号, 当然包括上行调度信息。 而宏小区作为 UE的 服务小区, 即: 服务增强专用传输信道(英文: Enhanced Dedicated Transport Channel, 简称: E-DCH ) 小区和服务高速下行共享信道(英文: High speed Downlink Shared Channel, 简称: HS-DSCH )小区必须是同一小区, 而服务小 区的确定是基于 UE测量的下行信号,此时由于宏小区下行信号质量仍好于微 小区, 所以宏小区仍是服务小区, 由于宏基站无法接收到或者无法正确的解 调 UE发送的上行信号, 导致宏基站无法正确根据 UE的调度信息来实现对 UE上行数据调度, 同时宏基站也无法对 UE实现调度,
同时, 目前有一种快速小区切换流程, 具体流程如图 2所示的方法为 UE 从微小区移动到宏小区时的执行流程, 在进行图 2所示的流程之前, UE的上 行服务小区以及下行服务小区都是 LPN, 其具体步骤如下:
501 , UE向 RNC上报检测到宏小区超过门限(事件 1A );
502, RNC向该宏基站 MacroNodeB下发携带了预配置参数的无线链路建 立请求, 在预配置参数中包括了服务 E-DCH 小区的配置参数以及服务 HS-DSCH 小区的下行配置参数, 或者称为上行 E-DCH 链路参数和下行 HS-DSCH链路参数;
503 , MacroNodeB向 RNC返回无线链路建立响应;
504, RNC向 UE发送激活集更新消息, 该激活集更新消息用于指示 UE 等待服务小区切换,并且在该激活集更新消息中携带了用于 UE进行上下链路 重配置的预配置参数;
505 , UE向 RNC返回激活集更新响应;
506, UE向 RNC上报当前信号最好小区发生改变 (事件 1D ), 即宏小 区的信号比 小区好;
507 , RNC向 MacroNodeB发送无线链路重配置准备请求;
508, MacroNodeB向 RNC发送无线链路重配置响应;
509, RNC向 LPN发送无线链路重配置准备请求;
510 , LPN向 RNC发送无线链路重配置响应;
511 , RNC向 LPN并且向 MacroNodeB下发无线链路重配置确认信息;
512 , MacroNodeB向 UE下发高速共享控制信道(英文: High Speed Shared Control Channel, 简称: HS-SCCH )指令, 该 HS-SCCH指令用于指示 UE根 据预配置参数配置对应的链路, 实现上下行服务小区切换。 此时, 可选的, LPN可以向 UE发送重配消息触发 UE进行上下行服务小区切换;
513 , UE配置上 HS-DSCH链路配置参数, 将服务 E-DCH小区以及服务 HS-DSCH小区切换到 MacroNodeB, UE向 RNC发送重配置完成消息。 上述 S01~S13描述的是 UE向上下行服务小区切换到 MacroNodeB的过 程, 在完成切换之后, 为了避免 MacroNodeB无法接收 UE上行数据的问题, 还需要完成上下行服务小区的解耦, 其具体过程如下:
重复执行步骤 S07 S11 , 然后再执行 S14, 区别在于之前的步骤 S07~S11 是将 MacroNodeB配置为上下行服务小区, 对应其链路也变为服务 HS-DSCH 链路和服务 E-DCH链路, 而将 LPN小区配置为非服务小区, 对应链路为非 服务 E-DCH链路,由于只有一条 HS-DSCH链路,所以此时 LPN没有 HS-DSCH 链路。 而在此时的步骤中, 是将 MacroNodeB 配置为下行服务小区和非上行 服务小区, 将 LPN配置为上行服务小区。;
514, MacroNodeB向 UE下发重配置指令, 该重配置指令中携带了配置 E-DCH链路的上行配置参数;
515, UE根据重配置指令中的上行配置参数重新配置 E-DCH链路, 使得 UE的服务 E-DCH小区为 LPN。
通过上述的流程就完成了上下行小区解耦,即:服务 E-DCH小区为 LPN, 服务 HS-DSCH小区为 MacroNodeB。
从上述的流程中可以看出, 在进行小区解耦之前, 首先要将上下行服务 小区切换到同一小区, 然后才能进行解耦, 这样使得解耦过程比较复杂, 而 且重复配置相关 E-DCH参数, 也加大的信令开销, 导致资源浪费。 发明内容

首先来讲, 本发明实施例中的小区切换方法至少可以应用到如下 3种网 络架构中:
图 1所示为微小区 Pico与宏小区 NodeB之间的网络架构,针对图 1所示 的网络架构就不再赘述。 图 3 所示为微小区与宏小区的另一种网络架构, 在 图 3的网络架构中, 微小区中的微基站有单独的 RNC管理, 该管理微基站的 RNC与宏 RNC通过现有的逻辑接口 lur向相连, 微基站通过 lub与 RNC相 连并通过 lur与宏 RNC交互信息,图 1与图 3的网络架构中微小区和 RNC之 间都是基于 Iub接口通信。
如图 4所示的网络架构中, 微基站实现无线网络控制器和基站网络的功 能,基站网络起到汇集功能,微基站通过 Iuh或者 Iurh接口与基站网络相连, 并通过 lur接口与 RNC相连,微基站与 RNC交互信息需要通过基站网络转发。
本发明实施例所提供的方法对上述 3种网络架构都适用, 图 1所示的网 络架构为基础网络架构,图 3以及图 4所示的网络架构都是图 1的演进架构, 所以若是对图 1所示的网络架构适用, 则肯定对图 3以及图 4所示的网络架 构适用, 所以在下面的实施例中都以图 1所示的网络架构进行描述。
为了解决当前小区解耦过程繁瑣, 重复传输配置参数带来信令开销较大 的问题, 因此本发明实施例中提供了一种小区切换的方法、装置及系统, 即: 接收 RNC发送的第一操作指示以及预配置参数; 若第一操作指示用以指示下 行服务小区切换,根据下行 HS-DSCH链路的配置参数将下行服务小区从服务 小区切换至目标小区, 上行服务小区保持不变; 若第一操作指示用以指示只 进行上行服务小区切换, 根据上行 E-DCH链路的配置参数将上行服务小区从 服务小区切换至目标小区, 从而在完成小区切换的过程中的同时也完成了小 区解耦,避免了 UE将上下行服务小区同时切换到目标小区之后再进行解耦的 繁瑣过程, 提升了服务小区解耦的效率, 同时也避免了重复传输配置参数带 来的信令开销, 节约了系统资源。
下面通过附图以及具体实施例对本发明技术方案做详细的说明。
实施例一:
如图 5所示为本发明实施例中小区切换的方法流程图, 该方法包括: S501 , 接收无线网络控制器 RNC发送的第一操作指示以及预配置参数, 若是该第一操作指示用以指示下行服务小区切换时, 执行 S502, 若是第一操 作指示用以指示上行服务小区切换时, 执行 S503; 5502,在预配置参数中获取下行高速物理下行共享信道 HS-DSCH链路的 配置参数,并根据下行 HS-DSCH链路的配置参数将下行服务小区从服务小区 切换至目标小区, 上行服务小区保持在服务小区;
5503 ,在预配置参数中获取上行增强专用传输信道 E-DCH链路的配置参 数, 并根据上行 E-DCH链路的配置参数将上行服务小区从服务小区切换至目 标小区。
由于 UE在小区间移动可能会出现从微小区移动至宏小区,也可能出现从 宏小区移动至微小区, 而本发明实施例所提供的方法对两种情况都适用, 下 面分情况进行说明:
情况一: UE从微小区移动至宏小区, 此时的目标小区为宏小区, 服务小 区为微小区。
在 UE从微小区移动至宏小区时, UE会向 RNC上报 1A事件,此时 RNC 将确定需要为 UE在宏小区中建立链路, RNC将向宏小区下发链路建立请求 消息, 其中在链路建立请求消息中了携带用于之后切换的预配置参数和当前 建立链路的参数(建立称为非服务 E-DCH链路)。
可选的, 在链路建立请求消息中携带第一操作指示, 该第一操作指示用 于指示之后的切换是只切换上行服务小区, 或者只切换下行服务小区或者上 下行服务小区同时按照预配置参数切换, 其中, 第一操作指示可以包含在无 线链路建立请求或者无线链路添加或者同步无线链路重配请求或者非同步无 线链路重配请求消息中。
RNC在接收到宏小区返回的表征链路建立完成的响应消息时, RNC将向 UE下发激活集更新消息, 在该激活集更新消息中携带了第一操作指示以及预 配置参数,该第一操作指示用于指示 UE在之后快速服务小区切换时根据预配 置参数, 只进行上行服务小区切换或者只进行下行服务小区切换, 或者上下 服务小区切换, 在本发明实施例中快速服务小区切换即为小区切换。
在激活集更新消息中还携带了预配置参数, 该预配置参数中包含了用于 UE配置 HS-DSCH链路和 /或者 E-DCH链路的配置参数, 具体来讲, 在小区 切换的过程中主要涉及到的是下行服务小区的切换, 因此在预配置参数中必 须配置 HS-DSCH链路的配置参数, 可以选择性的配置 E-DCH链路的配置参 数。 可选的, 如果第一操作指示要求 UE只切换下行服务小区, 则在预配置参 数中, 可只携带配置 HS-DSCH链路的配置参数, 而不携带配置 E-DCH链路 的配置参数。
这里需要说明的是, HS-DSCH链路的配置参数可以是服务 HS-DSCH小区信 息, 包括: HARQ相关信息、 主扰码、 下行高速物理下行共享信道(英文: High Speed Physical Downlink Shared Channel , 简称: HS-PDSCH )信息、 服 务小区变化消息类型、 等一个或多个组合的信息。 而 E-DCH链路的配置参数 可以包括主扰码信息、绝对授权信道 E-AGCH信息、 E-DCH专用物理控制信道 E-DPCCH的功率偏置信息、 调度信息功率偏置、 相对授权信道 E-RGCH信息 等一个或多个组合的信息。
在 UE得到激活集更新消息之后, UE将向 RNC上报激活集更新完成的 消息。 由于此时还未进行小区的切换, 此时 UE将暂时不使用第一操作指示以 及预配置参数。
当 UE检测到宏小区的信号质量成为最好小区,也就是 UE检测到宏基站 的信号质量足够好时, UE会向 RNC上报小区切换的触发 1D事件,此时 RNC 将向宏基站下发链路重配置消息, 同时 RNC还会向微基站下发链路重配置消 息, RNC向宏基站下发的链路重配置消息用以指示宏基站配置与 UE之间的 HS-DSCH链路, 而 RNC向微基站下发的链路重配置消息用以指示微基站中 断与 UE之间的 HS-DSCH链路。
可选, 宏基站和微基站可以根据之前收到的第一操作指示和预配置参数 来进行链路重配, 这样相应的在该重配流程中可以不用携带对应的 HS-DSCH 链路参数和指示微基站中断与 UE之间 HS-DSCH链路。
当宏基站以及微基站的链路重配置完成时, 宏基站以及微基站都会向 RNC返回确认消息, 这样宏基站以及微基站的重配置过程完成。 在宏基站完成配置之后,宏基站将向 UE下发高速共享控制信道指示(英 文: High Speed Shared Control Channel order, 简称: HS-SCCH order ), 该指 示用于指示 UE进行小区切换, UE在接收到该 HS-SCCH指示之后, UE将调 取出预先从 RNC接收到的第一操作指示, 根据该第一操作指示, 该第一操作 指示用以指示 UE只切换下行服务小区, 保留上行 E-DCH链路参数, UE确 定需要切换下行服务小区时, UE还将调取出从 RNC接收到的预配置参数, 并从该预配置参数中获取用于配置下行 HS-DSCH链路的配置参数, 基于该 HS-DSCH链路的配置参数, UE将重配置 HS-DSCH链路, 使得 UE与宏基站 之间的链路一致, 然后 UE将下行服务小区切换至宏基站对应的宏小区, 即宏 小区作为 UE的下行服务小区, 当然微小区仍然作为 UE的上行服务小区, 对 应的上行服务小区和相关上行所有链路的配置都不变。
在上述的流程中, UE在完成小区切换的同时, 也完成了上下行服务小区 的解耦, 即将上行服务小区仍然滞留在微小区, 而下行服务小区切换至宏小 区, 这样就避免了将上下行服务小区同时切换至目标小区后再进行解耦的繁 瑣过程, 并且也减少了 RNC与宏基站、 微基站以及 UE之间的信息交互, 节 省了网络资源。
下面通过 RNC与宏基站、 微基站、 UE之间的信令交互流程来对本发明 技术方案做进一步的说明, 如图 6所示:
图 6所示的流程为 UE从微小区移动到宏小区时, UE、 LPN、宏基站 Macro NodeB之间的信息交互流程, 在该信息交互流程包括了如下的步骤:
5601 , UE向 RNC上报宏小区下行信号质量超过一定门限的 1A事件;
5602, 在 RNC指示 Macro NodeB完成链路建立之后, UE将接收 RNC 下发的激活集更新消息,在该激活集更新消息中携带了用于指示 UE进行小区 切换的第一操作指示以及用于重配置上行和 /或下行服务小区的预配置参数;
5603 , UE向 RNC返回激活集更新完成消息; 5604, 在 RNC指示 LPN、 Macro NodeB完成链路重配置之后, UE将接 收到 Macro NodeB下发的 HS-SCCH指示, 该 HS-SCCH触发 UE进行小区切 换;
5605, UE将调取出从 RNC接收到的第一操作指示以及预配置参数, UE 将根据第一操作指示以及预配置参数将下行服务小区切换至 Macro NodeB, 而上行服务小区仍然为 LPN。
5606, UE向 RNC发送小区切换完成的消息。
上述的流程中以 UE作为执行主体来描述,在 UE进行小区切换的同时就 完成的小区解耦,这样使得 UE的上下行服务小区解耦更加简便,提升了小区 解耦效率。
进一步, 在本发明实施例中, 在步骤 S501之前, UE还将上报是否支持 增强上下行服务小区解耦的能力,或者称为"快速解耦上下行服务小区",该增 强上下行服务小区解耦的能力表示 UE支持在切换的流程中执行上下行服务 小区分离,若 UE支持增强上下行服务小区解耦的能力则 UE还将向无线网络 控制器 RNC上报支持增强上下行服务小区解耦能力消息, 因此在执行 S501 之前 RNC根据 UE上报的消息, 来确定 UE是否进行下行服务小区切换和上 下行服务小区解耦, 该能力信息可以在 UE建立无线资源控制 (英文: Radio Resource Control, 简称: RRC )连接时上报给 RNC。 这样避免 RNC对不支持 增强上下行服务小区解耦的能力的 UE进行增强的切换流程配置,导致 UE切 换发生错误。
进一步, 在本发明实施例中, 在执行 S503之后, 此时在完成快速小区切 换后, 保持上行服务小区不变即处于上下行服务小区解耦状态后, 如果网路 侧触发将上行服务小区切换回宏小区, 则可以在对应的重配消息, 比如: 无 线承载重配消息或者传输信道重配消息或者物理信道重配消息或者无线链路 重配请求消息等,携带用以指示 UE将上行服务小区切换至宏小区的第二操作 指示时 UE将在重配置消息中获取到第二操作指示,在该场景下, 第二操作指 示表示只切换 UE的上行服务小区。 若是 UE在预配置参数中包含了上行 E-DCH链路的配置参数时, 则 UE 将获取该 E-DCH链路的配置参数, 最后根据第二操作指示, UE将根据预配 置参数中的上行 E-DCH链路的配置参数, 重配置 E-DCH链路, 从而将上行 服务小区切换至宏小区。 这样 RNC不需要在对应的重配置消息中再携带与预 配置一样的 E-DCH链路配置参数, 节约了信令开销。
情况二: UE从宏小区移动至微小区, 此时的目标小区为微小区, 当前小 区为宏小区。
在情况一的流程中说明的是 UE从微小区移动到宏小区时, UE与 RNC、 微基站、 宏基站之间的交互过程, 当然, 图 5所示的方法还可以应用到 UE从 宏小区移动到微小区的过程。
这里需要说明的是, UE从微小区移动到宏小区是直接进行小区切换, 同 时完成下行服务小区切换和解耦过程,而 UE从宏小区移动到微小区是先进行 小区解耦再进行下行服务小区切换。
所以, 当 UE从宏小区移动至微小区时, UE首先要进行上下行服务小区 解耦再进行下行服务小区切换, 具体过程如下:
解耦过程:
首先 UE向 RNC上报微小区的 1A事件, RNC确定需要在微小区中为 UE添加链路, 因此 RNC会向微基站下发链路建立请求消息 , 该链路建立请 求消息用以指示微基站建立与 UE之间的链路,在微基站完成与 UE之间的链 路建立之后, 宏基站向 RNC返回链路建立完成的响应消息。 在此无线链路建 立过程中, RNC可以配置微基站预配置参数, 该预配置参数可以包含
HS-DSCH链路和 /或 E-DCH链路的配置参数, 该预配置参数可以用于之后上 下行服务小区解耦过程, 或者在解耦过程之后的下行服务小区切换过程, 此 时可以通过增加的第一操作指示来指示微基站之后的上下行服务小区解耦过 程或者是之后的下行服务小区切换过程中, 是只切换上行服务小区, 或者只 切换下行服务小区, 或者同时切换上下行服务小区。 可选的, 也可通过无线链路建立过程进行上下行服务小区解耦过程, 此 时该过程可将 UE在微小区的链路建立为服务 E-DCH链路, 但不配置
HS-DSCH链路参数, 此时还可以携带第一操作指示, 第一操作指示用于指示 UE在之后进行的服务小区切换过程中, 根据预配置参数, 将 UE在微小区的 链路配置为服务 HS-DSCH链路, 而服务 E-DCH链路的参数不变。
UE将接收 RNC下发的激活集更新消息 ,该激活集更新消息用以指示 UE 确定小区切换的条件, 在该激活集更新消息中还携带了预配置参数以及可选 携带第一操作指示, 该预配置参数包括了用于进行上行 E-DCH链路配置的配 置参数和 /或用于下行 HS-DSCH链路配置的配置参数, 在激活集更新消息中 携带的第一操作指示用以指示 UE进行上行服务小区的切换还是下行服务小 区的切换, UE接收到预配置参数以及第一操作指示之后, 将暂时保存该预配 置参数以及第一操作指示。
在 UE完成激活集更新之后, UE向 RNC返回激活集更新的响应消息, 在 UE完成激活集更新之后, 如果 UE在微小区的链路满足一定条件, 且此时 UE没有处于上下行服务小区解耦的状态, RNC将向宏基站以及微基站下发链 路重配置消息, 宏基站以及微基站将根据 RNC下发的链路重配置消息进行链 路重配置, 即:将宏基站与 UE之间的链路配置称为非服务 E-DCH链路, 而将 微基站与 UE之间的链路配置为服务 E-DCH链路,此时 UE的服务 E-DCH链 路和服务 HS-DSCH链路在不同小区,在宏基站以及微基站完成链路重配置之 后, 宏基站以及微基站将向 RNC返回链路重配置完成的响应消息, 此时完成 Iub和 Iur接口上 UE上下行服务小区解耦的配置。
在得到宏基站以及微基站返回的响应消息之后, UE将接收到 RNC下发 的链路重配置消息, 该消息中携带第一操作指示, 该第一操作指示用于指示 UE在解耦后进行的服务小区切换流程中, 只切换下行服务小区, 而 E-DCH 相关链路参数不发生改变, UE将根据该链路重配置消息, 其中包含新的
E-DCH链路配置参数, UE根据该参数配置将上行服务小区切换到微小区,并 将在宏小区的链路改变为非服务 E-DCH链路。在 E-DCH链路配置完成之后, UE的上行服务小区就对应的切换至微小区, 而下行服务小区还是原来的宏小 区。 这样就完成了 UE上下行服务小区解耦。
可选的,如果 UE在之前激活集更新消息中得到的预配置参数包含 E-DCH 链路配置参数, 此时 UE按照重配消息中的 E-DCH链路参数进行重配, 而忽 略预配置参数中的相关参数。或者, UE根据在重配消息中获得第一操作指示, 忽略预配置参数中的相关 E-DCH链路参数。
服务小区切换流程:
在 UE完成上下行服务小区解耦之后,若是 UE检测到微小区成为最好小 区时, 则 UE向 RNC上报用以触发小区切换的触发事件 1D事件, 简单来讲 就是 UE上报 RNC需要对下行服务小区进行切换。
当 RNC接收到 UE发送的触发事件时, 此时 RNC将向微基站以及宏基 站下发链路重配置消息, 当然 RNC向宏基站下发的链路重配置消息用以指示 宏基站中断宏基站与 UE之间的 HS-DSCH链路, 而 RNC向微基站下发的链 路重配置消息用以指示微基站建立与 UE之间的 HS-DSCH链路。
可选, 宏基站和微基站可以根据之前收到的第一操作指示, 使用预配置 参数中 HS-DSCH链路参数,可以将宏基站变为 UE的非服务 HS-DSCH小区, 将微基站切换为 UE的服务 HS-DSCH小区, 而 E-DCH链路的配置参数保持 不变。
在 RNC接收到宏基站以及微基站返回的表征链路重配置完成的响应信息 之后, 小区切换的执行方法还是按照 S501 S502执行。 即: UE在检测到微小 区发送的用于指示 UE进行小区切换的切换指令时,这里的切换指令为微基站 下发的 HS-SCCH命令, 指示 UE进行服务小区切换, 或者宏小区可以向 UE 发送重配请求消息要求 UE进行服务小区切换。
在 UE接收到 HS-SCCH命令之后, UE将根据存储的第一操作指示, 以 及根据预配置参数中获取 HS-DSCH链路的配置参数, UE进行 HS-DSCH链 路的重配置, 在 HS-DSCH链路重配置完成之后, UE的下行服务小区将切换 至微小区, 此时上行服务小区以及下行服务小区都为微小区, 这样完成了下 行服务小区切换, 最后 UE会向 RNC上报小区切换完成消息。
这里需要说明的是上述的操作指示并不携带在激活集更新消息中, 而是 携带在 RNC向 UE下发链路重配置请求消息中。 当然在实际的应用场景中, 该操作指示也可以选择携带在激活集更新消息中。
这样切换的整个切换的过程完成。
在上述的切换过程中, UE将根据第一操作指示直接进行下行或者是上行 服务小区切换, 而不再是进行上下行服务小区解耦后, 也不会在切换流程中 再重新配置一遍 E-DCH链路参数, 这样不但避免了小区切换过程的复杂处理 步骤, 也减少了配置信令的开销, 提升了小区解耦的效率。
进一步, 在完成服务小区切换的预配置流程之后, 即在 UE上报 1A事件 后, RNC可以给基站和 UE发下第一操作指示, 用于指示之后的增强切换过 程中是只切换下行服务小区, 同时预配置参数中包含 E-DCH链路参数和 HS-DSCH链路参数。 若是进行上下行服务小区解耦时, RNC会向 UE或者基 站再次下发链路重配置消息, 在该链路重配置消息中携带一个第二操作指示, 该第二操作指示用于指示 UE在此重配过程中, 只切换上行服务小区, 并且使 用预配置参数中的 E-DCH链路的配置参数对 E-DCH链路进行配置, 最后将 上行服务小区切换至目标小区, 这样就不必在该重配置消息中携带 E-DCH链 路配置参数, 而仅仅是发一个指示即可, 这样也节省了网络开销, 提升了小 区解耦效率。
进一步, 在完成服务小区切换的预配置流程之后, 即在 UE上报 1A事件 后, RNC可以给基站和 UE发下第一操作指示, 用于指示之后的上下行服务 小区过程中只切换上行服务小区, 同时预配置参数中包含 E-DCH链路参数和 HS-DSCH链路参数。 若是进行上下行服务小区解耦时, RNC会向 UE或者基 站再次下发链路重配置消息, 在该链路重配置消息中携带一个第二操作指示, 该第二操作指示用于指示 UE在解耦后的服务小区切换流程中,只切换上行服 务小区, 并且使用预配置参数中的 E-DCH链路的配置参数对 E-DCH链路进 行配置, 最后将上行服务小区切换至目标小区, 这样就不必在该重配置消息 中携带 E-DCH链路配置参数, 而仅仅是发一个指示即可, 这样也节省了网络 开销, 提升了小区解耦效率。
另夕卜,若是在预配置参数中没有包含用于配置 E-DCH链路的配置参数时, 则此时在上下行服务小区解耦过程中的重配流程中, RNC需要将新的 E-DCH 链路参数配置给 UE和基站,使上行服务小区切换到目标小区, 而下行服务小 区仍保留在原小区, 同时 RNC在预配置流程或者重配进行上下行服务小区解 耦流程中会携带了一个操作指示,该操作指示用以指示 UE只进行下行服务小 区切换, 即在服务小区切换流程中根据预配置参数中包含的用以配置
HS-DSCH链路的配置参数配置相关链路, 从而使 UE的下行服务小区切换至 目标小区, 而上行服务小区仍然保留原配置, 即在解耦后仍在目标小区中。
进一步,在本发明实施例中为了保证 UE能够准确进行上下行服务小区解 耦和服务小区切换过程, UE还将上报是否支持上下行服务小区解耦的能力, 或者称为,,快速解耦上下行服务小区",该能力表示 UE支持在小区切换的流程 中执行上下行服务小区分离, 则 UE还将向无线网络控制器(英文: Radio Network Controller, 简称: RNC )上报支持上下行服务小区解耦能力消息, 因此在执行第一步骤之前 RNC根据 UE上报的能力信息, 来配置 UE进行下 行服务小区切换和上下行服务小区解耦,该能力信息可以在 UE建立无线资源 控制 (英文: Radio Resource Control, 中文: RRC )连接时上报给 RNC。 这 样避免 RNC对不支持该能力的 UE进行增强的切换流程配置, 导致 UE切换 发生错误。
如图 7所示, 通过 UE与 RNC、 LPN、 Macro NodeB之间的通信流程图 来对第二种情况作进一步的说明:
5701 , UE向 RNC上报 UE从宏小区移动至微小区的事件;
5702, UE接收 RNC下发的激活集更新消息, 该激活集更新小区中携带 了第一操作指示以及预配置参数,激活集更新消息用以指示 UE确定小区切换 的条件, 第一操作指示用以指示 UE将上行服务小区切换至微小区; 5703 , UE向 RNC返回激活集更新完成的响应消息;
5704,在 RNC指示 LPN以及 Macro NodeB完成链路重配置之后, UE将 接收 RNC下发的链路重配置消息, 该链路重配置消息用以指示 UE重配置 E-DCH链路以及切换小区;
5705, UE将根据预配置参数中的 E-DCH链路的配置参数重配置 E-DCH 链路, 并根据第一操作指示将上行服务小区切换至微小区。
通过上述的 S701~S705, UE就完成了上行月良务小区和下行月良务小区的解 耦, 当然,在解耦之后还会进一步的执行服务小区的切换,切换的流程如下:
5706, 当 UE检测单微小区的信号质量大于等于阔值时,则 UE会向 RNC 上报小区切换的触发事件;
5707, UE将接收到 U C再次下发的激活集更新消息, 在该激活集更新 消息中携带了第二操作指示,该第二操作指示用以指示 UE将下行服务小区切 换至 LPN;
5708 , UE向 RNC返回激活集更新完成的消息;
5709, 在 RNC指示 LPN以及 Macro NodeB再次完成链路重配置之后, UE将接收到 LPN下发的 HS-SCCH指示, 该 HS-SCCH指示用以指示 UE进 行服务小区切换;
5710, UE将根据第二操作指示将下行服务小区切换至 LPN。
通过 S706~S710, UE完成了服务小区的切换过程,从上述的切换流程中, UE将不再需要将上行服务小区以及下行服务小区切换至微小区之后, 再进行 服务小区解耦, 从而减少了服务小区解耦的步骤, 进而提升了服务小区解耦 的效率。
实施例二:
在本发明实施例中还提供了一种小区切换的方法, 如图 8所示为本发明 实施例中一种小区切换方法的流程图, 该方法包括: 5801 , 当接收到用户设备上报的表征用户设备从当前小区移动至目标小 区的第一触发事件时, 生成用以指示所述用户设备的上行服务小区或下行服 务小区切换至所述目标小区的第一操作指示;
5802,确定出用于配置用户设备下行高速物理下行共享信道 HS-DSCH链 路和 /或上行增强专用传输信道 E-DCH链路的预配置参数;
5803 , 将第一操作指示以及预配置参数下发至所述用户设备, 以使用户 设备根据第一操作指示以及预配置参数将下行服务小区或上行服务小区切换 至目标小区。
下面还是分 UE从微小区移动至宏小区和 UE从宏小区移动至微小区这两 种情况来说明:
情况一: UE从微小区移动至宏小区, 此时目标小区为宏小区, 当前小区 为微小区。
在 UE从微小区移动至宏小区的过程中, UE将该事件上报至 RNC, 此时 RNC基于 UE上报的事件确定出当前需要为 UE在目标小区中添加链路, 在 目标小区中添加的链路可能是 E-DCH链路或者是 HS-DSCH链路。
在确定需要在宏小区中添加链路之后, RNC会向目标小区下发链路建立 请求消息, 其中在链路建立请求消息中了携带用于之后切换的预配置参数和 当前建立链路的参数, 比如建立称为非服务 E-DCH链路。
可选的, 在链路建立请求消息中携带第一操作指示, 该第一操作指示用 于指示之后的切换是只切换上行服务小区, 或者只切换下行服务小区或者上 下行服务小区同时按照预配置参数切换, 其中, 第一操作指示可以包含在无 线链路建立请求或者无线链路添加或者同步无线链路重配请求或者非同步无 线链路重配请求消息中。
在该链路建立请求消息中还可以携带包含了目标小区用于配置 E-DCH链 路以及 HS-DSCH链路的配置参数的重配置参数, 宏小区通过该 E-DCH链路 的配置参数可以配置与 UE之间的 E-DCH链路, 通过 HS-DSCH链路的配置 参数可以配置与 UE之间的 HS-DSCH链路,宏小区暂时不会使用该重配置参 数, 而是知道 UE需要进行小区切换时, 该重配置参数才会使用。
在 RNC接收到宏小区对应的宏基站返回的链路建立完成的消息时, RNC 将向 UE下发激活集更新流程消息,为了使 UE能够确定需要切换的服务小区 为上行服务小区还是下行服务小区, 因此 RNC会在下发至 UE的激活集更新 消息中将携带第一操作指示,该第一操作指示用于指示 UE在之后快速服务小 区切换时根据预配置参数, 只进行上行服务小区切换或者只进行下行服务小 区切换, 或者上下服务小区切换。
同时在该激活集更新消息中还会携带预配置参数, 该预配置参数包含了 用于配置 UE配置 HS-DSCH链路和 /或者 E-DCH链路的配置参数, 在 UE获 取到第一操作指示以及预配置参数之后, UE会暂时保存第一操作指示以及预 配置参数。
在 UE检测到宏小区的信号质量成为最好小区时, UE会向 RNC上报切 换小区的触发事件, UE通过该触发事件告知 RNC需要下行服务小区进行切 换, 此时 RNC将向宏基站下发链路重配置消息, 宏基站在接收到重配置消息 之后,宏基站将在重配置参数中获取用于配置与 UE之间的 HS-DSCH链路的 配置参数, 从而使得宏基站能够配置好与 UE之间的 HS-DSCH链路。
同时 RNC还会向微基站下发链路重配置消息, 微基站在接收到链路重配 置消息之后, 将中断与 UE之间的 HS-DSCH链路。
在宏基站以及微基站完成链路重配置之后, RNC可以选择性的向 UE下 发链路重配置指令, 该链路重配置指令用以指示 UE进行链路重配置, 即: UE 配置与宏基站之间的 HS-DSCH链路,当然也可以选择不下发该链路重配置指 令, 因为宏基站在向 UE下发小区切换指示时, UE也会进行链路重配置。
当然, 在 UE接收到宏基站下发的小区切换指示时, UE将调取出预先从 RNC接收到的第一操作指示, 根据该第一操作指示, 该第一操作指示用以指 示 UE只切换下行服务小区, 保留上行 E-DCH链路参数, UE确定需要切换 下行服务小区, UE还将调取出从 RNC接收到的预配置参数, 并从该预配置 参数中获取用于配置下行 HS-DSCH链路的配置参数, 基于该 HS-DSCH链路 的配置参数, UE将重配置 HS-DSCH链路, 使得 UE与宏基站之间的链路一 致, 然后 UE将下行服务小区切换至宏基站对应的宏小区, 当然上行服务小区 仍然滞留在原来的微小区, 对应的上行服务小区和相关上行所有链路的配置 都不变。
从上述的实施例中可以明显的得出, UE在从微小区移动至宏小区时, UE 将不再需要同时将上行服务小区以及下行服务小区同时切换到宏小区之后, 再进行将上行服务小区或者下行服务小区切换回微小区的解耦过程, 而是由 RNC通过向 UE下发第一操作指示来指示 UE进行上行服务小区切换还是下 行服务小区切换, 从而就可以单独的将需要切换的小区直接切换至目标小区, 进而避免了小区解耦的繁瑣过程, 提升了小区解耦的效率。
进一步, 在本发明实施例中, 在执行服务小区切换之前, RNC会确定是 否接收到 UE上报的是否支持上下行服务小区解耦的能力, 或者称为"快速解 耦上下行服务小区", 该上下行服务小区解耦的能力表示 UE支持在切换的流 程中执行上下行服务小区分离, 若 UE支持上下行服务小区解耦的能力则 UE 还将向无线网络控制器 RNC上报支持上下行服务小区解耦能力消息, 因此在 执行 S801之前 RNC根据 UE上报的消息,来确定 UE是否进行下行服务小区 切换和上下行服务小区解耦,该能力信息可以在 UE建立无线资源控制(英文: Radio Resource Control, 简称: RRC )连接时上报给 RNC。 这样避免 RNC对 不支持增强上下行服务小区解耦的能力的 UE进行增强的切换流程配置,导致 UE切换发生错误。
当然, 在完成快速小区切换后, 保持上行服务小区不变即处于上下行服 务小区解耦状态后, 如果网路侧触发将上行服务小区切换回宏小区, 则可以 在下发至 UE的重配消息, 比如: 无线承载重配消息或者传输信道重配消息或 者物理信道重配消息或者无线链路重配请求消息, 该重配置消息中携带用以 指示 UE将上行服务小区切换至宏小区的第二操作指示时,此时第二操作指示 表示只切换 UE的上行服务小区,UE将在重配置消息中获取到第二操作指示。 若是 UE在预配置参数中包含了上行 E-DCH链路的配置参数时, 则 UE 将获取该 E-DCH链路的配置参数, 最后根据第二操作指示, UE将根据预配 置参数中的上行 E-DCH链路的配置参数, 重配置 E-DCH链路, 从而将上行 服务小区切换至宏小区。 这样 RNC不需要在对应的重配置消息中再携带与预 配置一样的 E-DCH链路配置参数, 节约了信令开销。
情况二: UE从宏小区移动至微小区, 此时的目标小区为微小区, 服务小 区为宏小区。
在情况一中, 只需要 UE进行一次小区切换就可以同时完成小区解耦, 而 在情况二中, UE必须要先进行小区解耦然后才能够进行小区切换。
解耦过程:
小区解耦的过程也是在 UE上报从宏小区移动至微小区的事件后, RNC 的执行流程与情况一中的小区切换的流程基本相同,只是微小区不会向 UE下 发小区切换指令来触发 UE进行服务小区切换, 而是由 RNC向 UE下发链路 重配置消息来触发 UE进行服务小区切换, 当然 RNC还是会在进行服务小区 切换之前将第一操作指示以及预配置参数下发至 UE, 此时的第一操作指示是 用以指示 UE将上行服务小区切换至微小区, 而下行服务小区保持不变。
UE首先会向微基站下发链路建立请求消息, 该链路建立请求消息用以指 示微基站建立与 UE之间的链路, 在微基站完成与 UE之间的链路建立之后, 宏基站向 RNC返回链路建立完成的响应消息。在此无线链路建立过程中 , RNC 可以配置微基站预配置参数, 该预配置参数可以包含 HS-DSCH链路和 /或 E-DCH链路的配置参数, 该预配置参数可以用于之后上下行服务小区解耦过 程, 或者在解耦过程之后的下行服务小区切换过程, 此时可以通过增加的第 一操作指示来指示微基站之后的上下行服务小区解耦过程或者是之后的下行 服务小区切换过程中, 是只切换上行服务小区, 或者只切换下行服务小区, 或者同时切换上下行服务小区。
在微基站以及宏基站完成链路配置之后, RNC会向 UE下发链路重配置 消息, UE在接收到 RNC下发的链路重配置消息之后, UE将根据第一操作指 示以及预配置参数中的 E-DCH链路的配置参数, 将 UE的上行服务小区切换 至微小区, 而下行服务小区仍然为宏小区。
当然, UE在完成服务小区解耦之后, 若是 UE检测到微小区的信号质量 为最好时, UE将向 RNC上报进行服务小区切换的触发事件, 此时 RNC会向 UE下发激活集更新消息, 在该激活集更新消息中携带了第二操作指示, 该第 二操作指示用以指示 UE将下行服务小区切换至微小区。
RNC在接收到 UE上报的触发事件时, RNC将再次向微基站以及宏基站 下发链路重配置消息, 此时下发至微基站的重配置消息用以指示微基站配置 与 UE之间的 HS-DSCH链路, 下发至宏基站的重配置消息则是用以指示宏基 站中断与 UE之间的 HS-DSCH链路。
在微基站配置了与 UE之间的 HS-DSCH链路, 同时宏基站中断了与 UE 之间的 HS-DSCH链路时,微基站将向 UE下发 HS-SCCH指示,该 HS-SCCH 指示用以指示 UE进行小区切换,此时 UE将基于第二操作指示将下行服务小 区切换至微小区。 这样在切换的过程中, UE将不再需要将上行服务小区以及 下行服务小区同时切换至微小区之后, 再进行小区解耦, 从而减少了小区解 耦的步骤, 提升了小区解耦的效率。
实施例三:
本发明实施例二中的方法还可以应用到双载波技术中, 双载波技术是指 UE可在两个载频上进行高速上行链路分组接入 (英文: High Speed Uplink packet access, 简称: HSUPA ), Dual Cell E-DCH或者称为 DC-HSUPA, 即: UE在两个激活的载频上发送上行数据, 其中一个载频为主载频 primary frequency,在该主载频中可以包括上行主载频(英文: rimary uplink frequency ) 以及下行主载频 (英文: rimary downlink frequency ), 当然 UE上行主载频进 行上行发送, 下行主载频上进行下行接收。
另一个载频为辅载频 secondary frequency, 在该辅载频包含上行辅载频 (英文: secondary uplink frequency )和下行辅载频 (英文: secondary downlink frequency )。 UE在每个载频上都有一个上行服务小区或链路和下行服务小区 或链路, 当然还存在有若干个非上行服务小区或链路, 上行服务小区可以通 过发送绝对授权信道 E-AGCH来调度 UE的数据传输。
一般来讲, UE在进行上下行服务小区解耦之前, UE的上行服务小区和 下行服务小区处在同一个小区, RNC会在 Uu口配置 UE的载频上相关小区的 上行链路配置参数以及下行链路配置参数, 在 Iub口 RNC会配置基站相关上 下行链路配置参数。
目前在配置主载频的上行 E-DCH链路的配置参数时, RNC会下发 serving E-DCH RL indication上行服务小区指示来指示某条链路或者 Primary公共导 频信道(英文: Common Pilot Channel, 简称: CPICH )信息为服务上行 E-DCH 链路, 该 CPICH信息中可以包含主扰码(英文: primary scrambling code, 简 称: PSC ), —个小区有一个主扰码, 对应上行 E-DCH链路的小区为上行服务 小区; 同时 RNC会下发 serving HS-DSCH RL indication下行服务小区指示来 指示某条链路为下行 HS-DSCH链路, 对应下行 HS-DSCH链路的小区为下行 服务小区。
由于下行服务小区只有一个, RNC在下发辅载频上的上行 E-DCH链路的 配置参数时, 不会携带配置辅载频上的上行服务小区或者上行 E-DCH链路的 指示,而是使用配置的下行服务小区或者下行 HS-DSCH链路对应的小区作为 上行服务小区。
但是在上下行服务小区解耦后, 要求在解耦后两个频点的上行服务小区 在同一个基站, 而一个基站可以控制多个小区, UE在一个基站中可以建立多 条链路, 所以目前次频点上的上行服务小区在解耦后无法指示给 UE、 基站和 RNC, 这样就会造成了配置错误, 影响次频点上 UE的数据上发。
为了避免上述的问题, 本发明实施例中提供了一种指示小区的方法, 该 方法包括: 获取无线网络控制器 RNC发送的辅载频上的上行服务小区指示; 该上行服务小区指示包含了辅载频的上行服务链路的标识、 辅载频的上行服 务小区的扰码、 主载频和辅载频上的小区定时参考的配置信息中的一个信息 或者多个信息的组合; 若上行服务小区指示包含辅载频的上行服务链路的标识, 则确定上行服 务链路的标识所指示的链路为辅载频的上行服务链路; 或者, 若收到辅载频 的上行服务小区的扰码, 则确定含有上行服务小区的扰码的链路为辅载频的 上行服务链路。
具体来讲, 在本发明实施例中在 Uu口发送的消息中(可以是无线承载重 配消息或者传输信道重配消息或者物理信道重配消息或者无线链路重配请求 消息、 小区更新确认、 激活集合更新等消息)增加一个上行服务小区指示, 该指示包含了辅频点服务 E-DCH小区或链路指示;或者包含该小区的 Primary CPICH信息或扰码信息; 或者该指示可以是一个现有的信元 E-AGCH信息, 通过判断哪个小区或链路配置有 E-AGCH信息来确定哪个小区或哪条链路为 上行服务小区或上行 E-DCH链路, 即此时不需要额外添加这个指示, 而是隐 式通过现有信元做判断;或者 UE通过判断辅载频上的上行服务小区的定时参 考信息和主载频上的上行服务小区的定时参考信息相同来确定为辅载频的服 务 E-DCH小区, 其中定时参考信息可以是 F-DPCH的定时配置信息。
因此在 RNC向 UE下发上行 E-DCH链路配置参数时, 将携带上行服务 小区指示,从而 UE就能够根据该上行服务小区指示确定出辅载频上的上行服 务小区或者上行服务链路, 而同样该上行服务小区指示也可以携带在 Iub或 Iur接口上的相关消息中, 此处的相关消息可以是: 无线承载重配消息或者传 输信道重配消息或者物理信道重配消息或者无线链路重配请求消息等消息, 最后 RNC能够在解耦后将上行服务小区或者上行链路指示给 UE、 基站, 进 而避免了配置错误。
实际上来讲, 在该实施例中就是在 Uu口下发的消息中携带一个指示, 根 据该指示可以确定出 secondary频点上的上行服务小区或者是服务 E-DCH链 路,从而使得由于无法确定第二频点上的上行服务小区不会影响到 UE的数据 上发。
