Description

多流传输的配置方法、 基站、 无线网络控制器和用户设备 技术领域
本申请实施例涉及通信技术领域， 并且更具体地， 涉及一种多流传输的 配置方法、 基站、 无线网络控制器和用户设备。 背景技术
随着数据业务的爆发性增长， 常规宏基站或宏小区（Marco Cell, Mcell ) 无法提供更多的容量给越来越多的用户设备（User Equipment, UE ), 因而 出现了微基站或小小区（Small Cell, Scell )或微小区 (Micro Cell), 用以有效 提升网络容量。 一个宏小区内通常可以部署多个 基站， 基站对应的小小 区的覆盖范围小于宏基站对应的宏小区的覆盖范围。 例如， 可以在同构网络 ( Homogeneous network ) 内部署不同类型或不同制式的微基站， 例如， 低 发射功率的基站或发射 /接收节点， 包括匹克（Pico )基站、 家庭（Home ) 基站、微微 ( femto )基站、 中继站、远端射频头（ Remote Radio Head, RRH ) 等， 以增强网络的覆盖和性能， 这样的网络结构被称之为异构网络 (Heterogeneous network)。 小小区可以进一步提升用户的数据业务体验， 而宏 小区一般用于全覆盖，保证用户的实时类业务的覆盖以及提供速率较低的数 据业务。 小小区的频点与宏小区的频点可以相同或不同。 上述一个宏小区内 部署多个 基站的小小区场景可以包括以下两种： 1 )宏小区可以采用频点 1 , 而宏小区的覆盖范围下的多个小小区可以采用频点 2; 2 )宏小区和宏小区覆 盖范围下的多个小小区均采用相同的频点。
通用移动通信系统 ( Universal Mobile Telecommunications System , UMTS )版本 5 ( Rel-5 ) 中引入了高速下行分组接入 ( High Speed Downlink Packet Access , HSDPA )技术， 以进一步提升 UE的峰值吞吐和 '〗、区吞吐。 在 UE配置了 HSDPA后， 会配置一个高速下行链路共享信道（High-Speed Downlink Shared Channel, HS-DSCH )服务小区， UE的所有 HSDPA物理信 道，例如，高速共享控制信道（ High Speed-Shared Control Channel, HS-SCCH ) 和高速专用物理控制信道 ( High Speed-Dedicated Physical Control Channel, HS-DPCCH )都建立在这个 HS-DSCH服务小区上。 在 Rel-5引入 HSDPA技 术后， 由于 HS-DSCH服务小区仅有一个， 在 UE移动出当前服务小区并且 移动到新的小区后， 会触发 HS-DSCH服务小区变更。 服务小区变更主要通 过无线资源控制 （Radio Resource Control, RRC )信令完成， 需要完成宏基 站与无线网络控制器（ Radio Network Controller, RNC )以及 RNC与 UE之 间的信令交互。
UMTS技术演进到版本 11 ( Rel- 11 ) 时， 引入了多流传输（ Multiflow ) 技术，该多流传输技术允许将同频或异频上多个小区配置为 UE的 HS-DSCH 服务小区， 用户体验可以得到明显提升。 多流传输仅在 UE在小区边缘区域 时才使用， 即 UE处于软切换状态或更软切换状态时网络侧才可能配置多流 传输。这里软切换状态指 UE在不同基站下的同频两个小区的共同覆盖区域， 更软切换状态指 UE在同一个基站下的同频两个小区的共同覆盖区域。 在多 流传输技术中， 由于 HS-DSCH服务小区超过一个， 因而 UE的下行吞吐可 以获得较好的改善。
UE在小小区场景下移动时， 可能存在如下问题： 小小区可能彼此不相 邻的， 或重叠区域较少， 这样会导致较多的硬切换从而影响用户体验； 如果 按照现有的移动性流程，UE在不同的小小区间频繁移动，会触发较多的 RRC 信令， 这样会消耗较多的网络侧处理资源， 并且带来潜在的掉话风险。 发明内容

下面将结合本申请实施例中的附图，对本申请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申请一部分实施例， 而不是 全部的实施例。 基于本申请中的实施例， 本领域普通技术人员在没有作出创 造性劳动前提下所获得的所有其他实施例， 都属于本申请保护的范围。
应理解， 本申请的技术方案可以应用于各种通信系统， 例如： GSM ( Global System of Mobile communication,全球移动通讯 )系统、 CDMA( Code Division Multiple Access ,码分多址）系统、 WCDMA( , Wideband Code Division Multiple Access, 宽带码分多址）系统、 GPRS ( General Packet Radio Service , 通用分组无线业务）、 LTE ( Long Term Evolution, 长期演进） 系统、 LTE-A ( Advanced long term evolution, 先进的长期演进） 系统、 UMTS ( Universal Mobile Telecommunication System, 通用移动通信系统）等， 本申请实施例并 不限定， 但为描述方便， 本申请实施例将以 WCDMA系统为例进行说明。
本申请实施例可以用于不同的制式的无线网络。无线接入网络在不同的 系统中可包括不同的网元。例如， LTE和 LTE-A中无线接入网络的网元包括 eNB ( eNodeB , 演进型基站）， WCDMA 中无线接入网络的网元包括 RNC ( Radio Network Controller, 无线网络控制器）和 NodeB, 类似地， WiMax ( Worldwide Interoperability for Microwave Access , 全球微波互联接入 )等其 它无线网络也可以使用与本申请实施例类似的方案， 只^ ^站系统中的相关 模块可能有所不同， 本申请实施例并不限定， 但为描述方便， 下述实施例将 以 NodeB为例进行说明。
根据本发明的实施例的微基站可以包括 Pico基站、 Home基站、 femto 基站、 中继站、 RRH 以及其它低发射功率的小型基站。 本发明实施例将以 宏基站和微基站部署的异构网络为例进行说明，但是本发明实施例并不限于 此， 例如， 当 史基站为 RRH时， 本发明实施例同样适用。
还应理解， 在本申请实施例中， 用户设备（UE, User Equipment ) 包括 但不限于移动台 （MS , Mobile Station ), 移动终端（ Mobile Terminal )、 移动 电话 ( Mobile Telephone )、 手机 ( handset )及便携设备 ( portable equipment ) 等， 该用户设备可以经无线接入网（ RAN, Radio Access Network )与一个或 多个核心网进行通信， 例如， 计算机等， 用户设备还可以是便携式、袖珍式、 手持式、 计算机内置的或者车载的移动装置。 用户设备可以是移动电话（或 称为 "蜂窝" 电话）、 具有无线通信功能的计算机等， 用户设备还可以是便 携式、 袖珍式、 手持式、 计算机内置的或者车载的移动装置。
另外， 本文中术语"系统"和"网络"在本文中常被可互换使用。 本文中术 语"和 /或"， 仅仅是一种描述关联对象的关联关系， 表示可以存在三种关系， 例如， A和 /或 B , 可以表示： 单独存在 A , 同时存在 A和 B , 单独存在 B 这三种情况。 另外， 本文中字符 "/" , 一般表示前后关联对象是一种 "或" 的关系。
多流传输指 UE 能够在至少一个频点上的至少两个小区接收下行
HS-DSCH 数据， 网络侧能够在至少一个频点上的至少两个小区调度下行 HS-DSCH数据。 例如， 基站 1有小区 1 , 小区 2, 小区 3 , 都在频点 1上， 此时如果小区 1和小区 2有共同的覆盖区域， 则小区 1和小区 2可以进行多 流传输。 例如， 基站 1有小区 1 , 小区 2, 小区 3 , 小区 4, 小区 5 , 小区 6, 其中小区 1、 2和 3在频点 1上， 小区 4、 5和 6在频点 2上， 如果小区 1、 2 和小区 4、 5有共同的覆盖区域， 则小区 1、 2、 4和 5可以进行多流传输。 再如， 基站 1有小区 1 , 基站 2有小区 2, 如果小区 1和小区 2有共同的覆 盖区域， 则小区 1和小区 2可以进行多流传输。
应理解， 本申请的实施例的第一基站和第二基站可以在逻辑上分开， 但 物理上可以属于不同的基站或属于同一个基站。
为了进一步提升多流传输技术的价值，可以考虑将多流传输技术应用到 小小区场景中，也即将至少一个宏小区和至少一个小小区联合为一个用户调 度下行数据， 这样可以解决 UE在小小区之间移动时存在的硬切换问题， 进 一步提升用户的数据服务体验， 并且对用户的实时类业务没有明显影响。
如果多流传输中宏小区作服务小区， 而小小区作辅助服务小区， 那么由 于小小区间通常彼此不相邻， 当 UE在不同的小小区之间移动时， 在按照常 规测量流程来检测小小区的情况下，需要进行较多的测量并触发较多的 RRC 信令， 这样导致耗费大量的空口资源的结果。 按照常规机制， 如果 UE无法 成功发送上行 RRC信令，则会导致掉话，因而会触发过多的空口 RRC信令， 从而增加 UE的掉话概率， 对用户体验（尤其是实时语音）影响非常明显。
根据本申请的实施例考虑在小小区场景中优化多流传输的配置流程， 以 期在提升 UE的吞吐速率的同时不会对网络侧的信令交互产生较大的影响。
图 1A是根据本申请的第一实施例的通信系统的示意图。参见图 1A,宏 基站 110的小区 Cell-1是宏小区， 主要通过广覆盖保证实时类业务（比如语 音通话）的用户体验；而微基站 120的小区 Cell-21、微基站 130的小区 Cell-22 和微基站 140的小区 Cell-23是小小区， 各自负责覆盖范围区域内的热点覆 盖， 主要提升数据类业务的体验。 宏基站 110、 微基站 120、 微基站 130和 基站 140可以受 RNC 150的控制。 当 UE在这些热点覆盖区域内时， 可以 获得较好的数据业务服务。 例如， 当 UE在 Cell-21和 Cell-1的覆盖区域内 时， 可以考虑同时配置 Cell-21和 Cell-1为 UE的 HS-DSCH服务小区， 此时 UE可以保证实时业务体验的前提下， 可进一步提升数据类业务的吞吐速率 从而提升用户体验。
图 1B是根据本申请的第二实施例的通信系统的示意图。 参见图 1B, 与 图 1A的实施例不同的是， 在图 1B的实施例中， 基站 120、 基站 130和 微基站 140可以受 RNC 160的控制， 在这种情况下， RNC 150和 RNC 160 可以通过 Iur接口通信。
图 2 是根据本申请的第三实施例的多流传输的配置方法的示意性流程 图。
210, 第二基站接收第一无线网络控制器发送的第一检测指示， 其中第 一检测指示包含与第一基站建立连接的用户设备的标识信息， 第一基站受第 一无线网络控制器的控制。
220, 第二基站根据第一检测指示检测该用户设备是否在第二基站的覆 盖范围内。
230, 第二基站将检测到用户设备在第二基站的覆盖范围内的信息通知 第一无线网络控制器， 以便第一无线网络控制器根据检测的结果进行多流传 输的配置。
240, 第二基站根据第一无线网络控制器发送的配置指示和多流配置信 息进行多流传输的配置， 以便第一基站的小区和第二基站的小区作为多流服 务小区联合为该用户设备提供多流传输服务。
下面以第一基站为宏基站、 第二基站为微基站， 第一无线网络控制器为
RNC为例， 对根据本申请的实施例进行具体的说明。
例如， 一个 RNC可以控制多个基站， 该 RNC可以通过 Iub接口与这些 基站通信， 即该 RNC终止通向这些基站方向的 Iub接口， 并且该 RNC用于 管理这些基站所属小区的负荷控制、 拥塞控制和接纳控制等等。 受 RNC控 制的基站可以是宏基站， 也可以是微基站。 根据本发明的实施例， 宏基站可 以受该 RNC的控制， 而微基站可以受该 RNC的控制， 也可以受其它 RNC 的控制。
根据本发明的实施例， 多流传输可以指多个服务小区与 UE建立连接， 并且联合与 UE之间进行多个数据流的传输。 例如， 可以指一个宏基站的小 区和一个或多个微基站的小区联合为 UE提供多流传输服务。 换句话说， 一 个宏基站通过一个链路向 UE传输一个数据流， 同时一个或多个微基站通过 其它链路向 UE传输其它数据流。
根据本发明的实施例， 一个宏基站的覆盖范围内可以部署多个微基站， 换句话说， 微基站的覆盖范围与宏基站的覆盖范围有交叠。 这些微基站可以 与宏基站共同受一个 RNC的控制。 可选地， 也可以是宏基站受一个 RNC的 控制， 而这些微基站受其它 RNC的控制， 并且控制宏基站的 RNC与控制微 基站的 RNC之间通过 Iur接口进行通信。
具体而言， 在 UE接入宏基站之后， 宏基站的小区可以作为 UE 的 HS-DSCH服务小区。 RNC可以在 UE接入宏基站的过程中获取该 UE的标 识信息， 并且可以向一个或多个微基站发送包含该 UE的标识信息的检测指 示， 以指示微基站检测 UE是否在其覆盖范围内。 微基站可以检测 UE发送 的上行信号 （例如， 上行同步过程中的 UE发送的上行专用信道的信号）， 如果该微基站发现该上行信号中包含的 UE的标识信息与上述检测指示中包 含的 UE的标识信息相同， 则该微基站检测到 UE在该微基站覆盖范围内。 微基站还可以向 RNC发送检测响应，以通知 RNC微基站已经成功检测到该 UE在其覆盖范围内。 RNC在接收到该检测响应后， 可以触发对 UE、 微基 站和宏基站进行多流传输的配置， 这样， 微基站的小小区也作为 UE 的 HS-DSCH服务小区， 即微基站的小区和宏基站的小区作为多流服务小区联 合为该 UE提供多流传输服务。
换句话说， 微基站在成功检测到 UE在该微基站的覆盖范围内之后， 可 以将检测结果通知 RNC, 然后 RNC可根据微基站通知的检测结果进行多流 传输的配置。 如果微基站未成功检测到 UE在其覆盖范围内， 则不会向 RNC 发送检测响应或者通过检测响应通知 RNC微基站未成功检测到该 UE在其 覆盖范围内， 因此， RNC也就不会考虑将未成功检测 UE的微基站配置多流 传输。
例如， 上述标识信息至少包括以下信息的至少一个： UE 的上行扰码、 上行 DPCCH信道化码、 上行 DPCCH时隙格式， 根据本申请的实施例并不 限于此， 上述标识信息也可以是其它能够标识 UE的信息。
本申请的实施例可以由第一无线网络控制器指示第二基站检测与第一 基站建立连接的用户设备是否在第二基站的覆盖范围内， 并且根据上述检测 的结果进行多流传输的配置， 以便第一基站的小区和第二基站的小区联合为 该用户设备提供多流传输服务。 由于根据本申请实施例在实现多流传输的配 置时信令交互较少， 因此， 降低了系统的资源消耗， 并且可以降低 UE的掉 话概率， 提升用户体验。
在 230中， 第二基站在检测到该用户设备在第二基站的覆盖范围内的情 况下， 向第一无线网络控制器发送第一检测响应， 第一检测响应用于指示该 用户设备在第二基站的覆盖范围内。
例如， 该第一检测响应可以指第二基站示成功检测到 UE在其覆盖范围 内， 或者第一检测响应可以包含标志位， 例如， 标志位为 1指示微基站成功 检测到 UE在其的覆盖范围内， 标志位为 0指示第二基站未检测到 UE在其 的覆盖范围内， 反之亦然。
可选地， 作为另一实施例， 还包括： 第二基站接收第一无线网络控制器 根据第一检测响应发送的配置指示和多流配置信息。
例如， 第一无线网络控制器根据第一检测响应确定第二基站成功检测到 UE在第二基站的覆盖范围内的情况下， 可以向第一基站、 第二基站和 UE 发送配置指示和多流配置信息， 以便第一基站、 第二基站和 UE可以根据该 多流配置信息进行多流传输的配置。 例如， 第二基站接收到该多流配置信息 之后， 会根据该多流配置信息进行多流传输的配置， 使得第二基站的小区可 以作为 UE的多流传输服务小区。 该配置指示和多流配置信息可以是专用的 信令消息， 也可以用常规信令消息（例如， 无线链路建立消息）携带。 该配 置指示可以是标志位，也可以是将多流配置信息置于信令消息的固定信元上 来隐式地表示该配置指示。
可选地， 作为另一实施例， 第二基站接收第一无线网络控制器发送的多 流配置信息； 第二基站接收第一无线网络控制器根据第一检测响应发送的配 置指示。
例如， 第一无线网络控制器可以预先向第一基站、 第二基站和 UE发送 多流配置信息。 第一基站、 第二基站和 UE接收到该多流配置信息之后并不 进行多流传输的配置， 而是在接收到第一无线网络控制器的进一步发送的配 置指示之后才进行多流传输的配置。 在引入预先发送多流配置信息的机制 后， 网络侧可以预先将多流配置信息告知 UE, 并且当需要多流配置信息生 效时， 网络侧仅需要通过筒单的指示告知 UE即可， 这样可以避免使用较大 的 RRC信令， 从而提升了切换成功率， 并且缩短了切换时间。
图 2的多流传输的配置方法还包括：第二基站在接收到该配置指示之后， 通过物理层信令通知 UE根据该多流配置信息进行多流传输的配置； 和 /或， 第二基站向用户设备转发第一无线网络控制器发送的 RRC层重配置信令， 以通知用户设备根据多流配置信息进行多流传输的配置。
例如， 根据本申请的实施例可以采用两种方式通知 UE进行多流传输的 配置： 1 )通过物理层信令（例如， HS-DPCCH order )通知 UE进行多流传 输的配置； 2 )通过第一无线控制器发送的 RRC层信令（例如， RRC层重配 置信令）通知 UE进行多流传输的配置。 根据本申请的实施例可以采用上述 两种方式之一， 也可以采用这两种方式， 以提高 UE成功接收到上述配置指 示的概率。 通过物理层信令的方式通知 UE切换多流传输， 在切换时延上有 较大的优势， 并可以明显降低切换过程中的掉话比例。
根据本申请实施例， 该配置指示还携带激活时间， 用于指示第二基站在 该激活时间内根据该多流配置信息进行多流传输的配置， 其中在 240中， 第 二基站在接收到所述配置指示后，在该激活时间内根据该多流配置信息进行 多流传输的配置。
可选地， 也可以在该物理信令中携带激活时间， 用于指示用户设备在该 激活时间根据该多流配置信息进行多流传输的配置。
例如， 在配置指示和该物理层信令中携带激活时间的情况下， 可以使得 UE 和网络侧在该激活时间同时切换到新的多流传输服务小区进行多流传 输。
可选地， UE在完成切换到新的多流传输服务小区时， 可以向 RNC返回 切换响应。
图 2的多流传输的配置方法还包括： 第二基站接收第一无线网络控制器 发送的停止检测指示； 第二基站根据该停止检测指示停止检测该用户设备是 否在第二基站的覆盖范围内。
例如， 在第一无线网络控制器接收到第三基站发送检测响应时， 获知第 三基站已经检测到 UE在第三基站的覆盖范围内， 第一无线网络控制器可以 通知第二基站停止检测 UE是否在第二基站的覆盖范围内， 这样可以降低对 第二基站的系统资源消耗。
根据本申请的实施例， 第二基站可以根据 UE发送的上行信号中包含的 该用户设备的标识信息和第一检测指示中包含的该用户设备的标识信息是 否一致来确定该用户设备是否在第二基站的覆盖范围内。
根据本申请的实施例采用了微基站根据上行信号检测 UE是否在微基站 的覆盖范围内的方法，与 UE按照常规测量流程检测小小区的方法相比， RRC 信令显著减少， 节省了空口资源。
在 220中， 第二基站根据第一检测指示检测该用户设备是否在第二基站 的覆盖范围内可以采用如下几个方式。
第二基站根据上行同步规则来检测该用户设备是否在第二基站的覆盖 范围内。
例如， 如果在 UE进行上行同步过程中， 100ms内连续监测到 UE发送 的 10个上行信号， 则网络侧确定该 UE在其覆盖范围内， 否则， 网络侧确 定该 UE不在其覆盖范围内。
在本发明的另一实施例中， 第二基站根据第一检测指示中携带的规则来 检测该用户设备是否在第二基站的覆盖范围内， 比如， 该携带的规则为： 如 果第二基站在 X时间内，连续监测到 UE发送的上行信号至少为 Y个，则第 二基站认为该用户在该第二基站覆盖范围内，如果第二基站在 X时间内连续 监测到 UE发送的上行信号小于 Y个，第二基站认为该用户不在第二基站覆 盖范围内， 其中 X的单位可以为毫秒， Y为正整数， X和 Y在第一检测指 示中携带。 例如， X为 0到 5秒， Y为 0个到 100个。 优选地， X为 400ms, Y为 20个。
在本发明的另一实施例中， 第二基站根据预设的规则来检测该用户设备 是否在第二基站的覆盖范围内，比如预设规则为：如果第二基站在 X时间内， 连续监测到 UE发送的上行信号至少 Υ个，则第二基站认为该用户在该第二 基站覆盖范围内，如果第二基站在 X时间内连续监测到 UE发送的上行信号 小于 Υ个， 第二基站认为该用户不在第二基站覆盖范围内， 其中 X的单位 可以为毫秒， Υ为正整数。
可选地， 作为另一实施例， 图 2的多流传输的配置方法还包括： 第二基 站根据第一无线网络控制器发送的去配置指示进行该多流传输的去配置。
例如， 第一无线网络控制器可以根据 UE在小小区一段时间内的调度数 据量来确定是否对多流传输进行去配置。
可选地， 作为另一实施例， 图 2的多流传输的配置方法还包括： 第二基 站根据空口信道质量向第一无线网络控制器发送去配置请求； 第二基站接收 第一无线网络控制器根据该去配置请求发送的去配置指示； 第二基站根据该 去配置指示进行多流传输的去配置。
例如， 当第二基站根据 UE的反馈信息发现空口信道质量变差 （例如， 小于等于预设的阈值）时， 第二基站可以向第一无线网络控制器发送去配置 请求， 以请求第一无线网络控制器根据该去配置请求触发多流传输的去配 置。 第一无线网络控制器接收到该去配置请求之后， 可以向第一基站、 第二 基站和 UE发送去配置指示， 以指示第一基站、 第二基站和 UE进行多流传 输的去配置。 例如， 空口信道质量可以为信道质量指示符 （Channel Quality Indicator, CQI ), CQI的值越低， 空口信道质量越差， CQI的值越高， 空口 信道质量越好。
根据本申请的实施例， 第二基站受第一无线网络控制器的控制。
例如， 宏基站和微基站均受同一个无线网络控制器的控制。
可选地， 作为另一实施例， 第二基站受第二无线网络控制器的控制， 其 中第二基站通过第二无线网络控制器与第一无线网络控制器之间的接口与 第一无线网络控制器进行通信。
例如， 在 WCDMA 系统中， 敫基站和宏基站可以受不同的无线网络控 制器（RNC )控制， 不同的无线网络控制器之间可以通过 Iur接口通信。 在 这种情况下，根据本发明的实施例的第一无线网络控制器与第二基站（例如， 微基站）之间交互的上述检测指示、 上述检测响应和上述停止检测指示、 上 述多流配置信息以及上述多流配置信息的发送均通过第二无线网络控制器 和 Iur接口发送。
应理解， 上述检测指示、 检测响应、 停止检测指示、 配置指示、 以及多 流配置信息等信令消息可以是专用的信令消息，也可以是由常规信令消息携 带。
根据本申请的实施例在小小区场景使用多流传输的情况下， 能够有效减 少信令交互， 并且能够较为快速地触发对目标小小区的上报， 让 UE能有效 提体验多流传输的增益。
图 3 是根据本申请的第四实施例的多流传输的配置方法的示意性流程 图。 图 3的实施例与图 2的实施例相对应， 在此不再赘述。
310, 在用户设备与第一基站之间建立连接的情况下， 第一无线网络控 制器向第二基站发送第一检测指示，其中第一基站受第一无线网络控制器的 控制， 第一检测指示包含该用户设备的标识信息， 以便第二基站检测该用户 设备是否在第二基站的覆盖范围内；
320, 第一无线网络控制器根据用户设备发送的检测到用户设备在第二 基站的覆盖范围内的信息进行多流传输的配置， 以便第一基站的小区和第二 基站的小区作为多流服务小区联合为该用户设备提供多流传输服务。
例如， 以第一基站为宏基站， 第二基站为微基站， 第一无线网络控制器 为 RNC为例， 第一无线网络控制器可以在获知 UE接入宏基站的情况下， 向宏基站覆盖范围内的微基站发送上述检测指示。根据本申请的实施例并不 限于此， 例如， 当 UE离开一个小小区， 即离开一个微基站的覆盖范围时， 第一无线网络控制器会从 UE的多流服务小区中删除该小小区， 这时， 第一 无线网络控制器可以向宏基站的覆盖范围内的其它微基站发送检测指示， 或 者第一无线网络控制器可以周期性地向宏基站内所有微基站发送检测指示， 以便检测到该 UE的微基站的小小区作为新的多流服务小区进行多流传输， 从而实现小小区之间的切换。 由小在小小区的切换过程中， UE始终与宏基 站保持连接， 因此可以避免因硬切换而掉话。
本申请的实施例可以由第一无线网络控制器指示第二基站检测与第一 基站建立连接的用户设备是否在第二基站的覆盖范围内， 并且根据上述检测 的结果进行多流传输的配置， 以便第一基站的小区和第二基站的小区联合为 该用户设备提供多流传输服务， 由于根据本申请实施例在实现多流传输的配 置时信令交互较少， 因此， 降低系统的资源消耗。

可选地， 作为另一实施例， 图 3的多流传输配置方法还包括： 第一无线 网络控制器向第三基站发送第二检测指示， 第二检测指示包含该用户设备的 标识信息， 以便第三基站检测该用户设备是否在第三基站的覆盖范围内； 在 接收到第二基站发送的第一检测响应的情况下， 向第三基站发送停止检测指 示， 以便第三基站停止检测该用户设备是否在第三基站的覆盖范围内。
可选地， 作为另一实施例， 图 3的多流传输配置方法还包括： 第一无线 网络控制器接收第三基站发送的第二检测响应， 第二检测响应用于指示该用 户设备在第三基站的覆盖范围内； 根据预设的规则从第二基站和第三基站组 成的组中选择第二基站用以进行该多流传输， 其中在 310中， 可以向所选择 的第二基站发送第一检测指示。
例如， 在第二基站和第三基站均返回了检测响应的情况下， 可以按照接 收检测响应的顺序来选择， 例如， RNC先从第二基站接收到检测响应， 后 从第三基站收到检测响应， 则 RNC选择第二基站作为多流传输服务小区。
可选地， 可以根据微基站的小区负载、 和 /或接入小区的 UE的数目、 和 /或小区可用资源数等信息来选择， 例如， RNC选择小区负载较轻的小区作 为多流传输服务小区。
根据本申请的实施例， 第一基站为宏基站， 第二基站为微基站。
可选地， 作为另一实施例， 图 3的多流传输配置方法还包括： 第一无线 网络控制器从第二基站接收去配置请求， 并且根据该去配置请求向第二基站 和用户设备发送去配置指示， 以便第二基站和用户设备进行多流传输的去配 置。

510, UE接入宏基站。 例如， UE通过 RRC信令与宏基站建立 RRC连接， 即接入到宏基站， 并且可以通过宏基站接收数据。
520, RNC向微基站 1发送第一检测指示。
例如， 在 UE接入宏基站后， RNC可以向微基站 1发送第一检测指示， 微基站 1可以是在宏基站覆盖范围内的微基站。 第一检测指示为唯一标识该 UE的信息， 例如， 第一检测指示可以包含与该 UE相对应的上行扰码、 和 / 或上行 DPCCH的信道化码、 和 /或上行 DPCCH时隙格式。
可选地，当 UE离开一个小小区，即离开一个微基站的覆盖范围时， RNC 也可以向宏基站的覆盖范围内的微基站发送检测指示， 或者第一无线网络控 制器可以周期性地向微基站发送检测指示， 以便检测到该 UE的微基站的小 小区作为新的多流服务小区进行多流传输。
525, 微基站 1检测该 UE是否在其覆盖范围内。
例如， 微基站 1在接收到 RNC发送的第一检测指示之后， 可以按照常 规上行同步过程中定义的规则 （ 3GPP TS 25.214的 4.3.2章节定义的规则 ) 来检测该 UE。 基站 1可以通过上行同步检测， 确定上行发送的信号 （例 如， DPCCH ) 中包含的该 UE的标识信息是否与第一检测指示中包含的 UE 的标识信息相匹配， 如果两者匹配， 则微基站 1成功检测到 UE在其覆盖范 围内。
可选地， RNC可以在检测指示中携带检测规则， 微基站 1可以根据该 检测规则确定 UE是否在其覆盖范围内。
根据本申请的实施例并不限于上述检测 UE的方法， 例如， 还可以新定 义检测规则， 微基站可以按照该新定义的检测规则来检测 UE。
530, 微基站 1向 RNC返回第一检测响应。
例如， 微基站 1在检测到 UE在其覆盖范围内时， 可以在第一检测响应 中携带标志位 1 , 微基站 1在没有检测到 UE在其覆盖范围内时， 可以在第 一检测响应中携带标志位 0。 可选地， 微基站 1也可以在检测到 UE在其覆 盖范围内时， 向 RNC发送第一检测响应， 而在未检测到 UE在其覆盖范围 内时， 不向 RNC发送第一检测响应。
540, RNC向微基站 2发送第二检测指示。
在 UE接入宏基站后， RNC可以向微基站 2发送第二检测指示，微基站
2可以是在宏基站覆盖范围内的微基站。 第二检测指示为唯一标识该 UE的 信息， 例如， 第二检测指示可以包含与该 UE相对应的上行扰码和 /或上行 DPCCH时隙格式。
545 , 微基站 2检测该 UE是否在其覆盖范围内。
例如， 微基站 2接收到 RNC发送的第二检测指示之后， 可以按照常规 上行同步过程中定义的规则 （ 3GPP TS 25.214的 4.3.2节定义的规则）来检 测该 UE。 微基站 2可以通过上行同步检测， 确定上行发送的信号 （例如， DPCCH )中包含的该 UE的标识信息是否与第二检测指示中包含的 UE的标 识信息相匹配，如果两者匹配，则微基站 2成功检测到 UE在其覆盖范围内。

560, RNC向微基站 2发送停止检测指示。
例如， RNC在从微基站 1接收到第一检测响应之后， 可以根据第一检 测响应确定 UE在微基站 1的覆盖范围内， 并通知其它微基站（例如， 微基 站 2 )停止检测 UE, 以避免微基站 2进行不必要的检测， 这样可以降低对 微基站 2的系统资源消耗。
570, RNC向微基站 1发送配置指示和多流配置信息， 以便微基站 1进 行多流的传输配置。
RNC在确定 UE在微基站 1的覆盖范围内之后，可以对微基站 1进行多 流传输的配置， 例如， 向微基站 1发送配置指示和多流配置信息， 并且在微 基站 1返回多流配置响应后完成多流传输的配置。
可选地， 例如， 如果出现多个 基站（例如， 图 5的实施例中 基站 1 和微基站 2 )都上报检测响应给 RNC的情况， 则 RNC需要选择一个合适的 微基站作为 UE的新的多流传输服务小区。 可以采用如下两种选择方式： 1 )按照接收检测响应的顺序来选择， 例如， RNC先从微基站 1收到该 检测响应， 后从微基站 2收到该检测响应， 则 RNC选择微基站 1作为多流 传输服务小区；
2 )根据微基站的小区负载、 接入小区的 UE 的数目、 小区可用资源数 等信息来选择， 例如， RNC选择小区负载较轻的小区作为多流传输服务小 区。
580, RNC向宏基站发送多流配置信息， 以便宏基站进行多流传输的配 置。
RNC还需要通知宏基站完成多流传输的配置， 因为在多流传输服务小 区个数发生变化时， 采用 HSDPA技术的系统的上行信道的格式可能发生变 化。 宏基站可以根据 RNC的通知对传输配置进行相应的变更。
590, RNC向 UE发送多流配置信息， 以便 UE进行多流传输的配置。 例如， RNC可以通过微基站 1向 UE发送多流配置信息， UE可以根据 接收到的多流配置信息进行多流传输的配置。 多流配置信息可以包括如下信 息的至少一个： 辅助服务小区的 HS-SCCH 信道化码、 辅助服务小区的 HS-PDSCH 信道化码、 UE 的上行 HS-DPCCH 信道化码、 UE 的上行 HS-DPCCH信道中的确认指示和非确认指示的发送功率偏置、 UE 的上行 HS-DPCCH信道中的信道质量指示的发送功率偏置、 UE的 HS-DSCH传输 信道到物理信道的映射信息、 UE的业务逻辑信道到 HS-DSCH传输信道的 映射信息等。

593, UE通过微基站 1接收数据。
UE和微基站 1完成多流传输的配置后，UE可以通过微基站 1接收数据， 从而实现多流传输。
进一步， 图 5的实施例还可以包括对多流传输进行去配置的过程。
594, RNC确定触发去配置多流传输。
RNC可以根据 UE在微基站 1的调度数据量来确定去配置多流传输。例 如， 在预设时段内， RNC检测到微基站 1请求的下行数据量少于某个门限， 或者 UE长时间（例如，超过预设时间）没有较多的下行数据调度，此时 RNC 可以触发去配置多流传输。 595, 微基站 1向 RNC发送去配置请求， 请求 RNC触发去配置多流传 输。
微基站 1根据空口信道质量请求 RNC去配置多流传输。 例如， 如果 UE 的反馈信息包含的信道质量和下行数据包的接收反馈长时间（例如， 超过预 设时间）较差， 则微基站 1可以发送去配置请求给 RNC, 以请求 RNC触发 针对该 UE的去配置多流传输。
应理解，根据本申请的实施例可以选择步骤 594的方式或步骤 595方式 触发去配置多流传输。
596, RNC向 UE发送去配置指示， 以便 UE根据该去配置指示对多流 传输进行去配置。
597, RNC向微基站 1发送去配置指示， 以便微基站 1对多流传输进行 去配置。
应理解， 步骤 540、 545和 550是可选的。 如果 UE在接入宏基站过程 中，在测量 告中携带了某个频点（小小区所在频点 )上小小区的测量信息， 那么 RNC在接收到该测量报告后， 可以仅向该小小区的微基站发送检测指 示， 这样可以对微基站的资源进行优化。 例如， 在图 5的实施例中， 可以仅 仅向微基站 1发送第一检测指示。
还应理解，根据本申请的实施例对向微基站 1和微基站 2发送检测指示 的顺序不作限制， 可以同时向 基站 1和 基站 2发送检测指示， 也可以先 向其中一个微基站发送检测指示，在确定该微基站没有检测到 UE的情况下， 再向另一个微基站发送检测指示。
还应理解， 根据本申请的实施例对向 UE、 微基站和宏基站发送多流配 置信息的顺序不作限制， 例如， 570、 580和 590可以同时执行， 也可以颠倒 顺序执行。
