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做出创造性劳动前提 下所获得的所有其他实施例， 都属于本发明保护的范围。
在本发明实施例中， 一般来说， 宏基站的发射功率大于容量站的发射 功率， 宏基站的覆盖范围也可以大于容量站的覆盖范围。 容量站也可称为 小基站， 也可称为低功率节点 （ Low Power Node, LPN ) 。 容量站可以有 多种类型，例如， 家庭基站（Home NodeB , 筒称 HNB )、微基站 (Micro Base Station, 筒称 Micro BS)、 微微基站（ Pico Base Station, 筒称 Pico BS或筒称 Pico基站）、 毫微微基站（FemtoCdl, 或 Femto Base Station ) 、 家庭演进基 站（ Home evolved Node B , HeNB )等。 在不同制式的网络系统中， 都可以 包括宏基站和容量站。 在本发明实施例中， 可以将将宏基站覆盖的网络称 为宏网络， 将容量站覆盖的网络称为微网络。 容量站可以位于宏网络的覆 盖范围内， 容量站可以处于宏基站的控制下。 微网络覆盖的范围内可以由 宏网络进行同覆盖。
在现有的无线通信系统中， 系统消息的广播需要占用大量无线帧的资 源， 例如 UMTS系统中， 系统消息会周期性广播， 并且为了保证覆盖， 系统 消息会一直以最大功率发射。而在频分双工（ Frequency Division Duplexing , 筒称 FDD ) UMTS网络下， CELL_DCH状态下的终端分配了专用信道， 能够 进行高速率的数据传送， 并且 CELL_DCH状态的终端是不需要读取系统消 息。 而容量站的特点是用户量少且相对固定、 网络情况变化慢， 解决覆盖 不足的同时， 能够提供高速率的速率业务。 因此， 当宏网络覆盖范围内有 受宏基站控制的微网络时， 由于宏网络宏基站提供了足够的有效覆盖， 从 资源利用效率、 用户服务质量（QoS )和绿色节能的需求出发， 可以基于网 络特性， 进行灵活设置， 使得当终端没有业务的时候就可以驻留在宏基站 覆盖的宏网络， 而容量站仅需维护业务量大的 CELL_DCH状态的终端进行 高速率的数据传输， 也仅需要维护 CELL_DCH的无线资源。
本发明实施例中所述终端可为单模终端也可为多模终端。 本发明实施 例中网络侧通信设备可以是宏网络中， 对宏基站进行控制的网络侧通信设 备， 网络侧通信设备也可以和宏基站集成在一个硬件设备中。
图 1为本发明实施例提供的一种通信方法流程图。 如图 1所示， 本实施 例包括：
步骤 11： 宏网络中的网络侧通信设备监测宏网络中的终端是否有微网 络业务需求； 微网络在宏网络覆盖范围内， 微网络内除导频信道之外的所 有公共物理信道或部分公共物理信道处于关闭状态。
宏网络中的终端是指该终端接入并驻留在该宏网络中。 本发明实施例 容量站可以关闭微网络中除导频信道之外的所有公共物理信道或部分公共 物理信道， 可减少容量站上广播信令的传输开销， 降低容量站的发射功率， 从而可以降低邻区干扰， 而且可以获得上、 下行的容量增益。 在本发明实 施例中， 关闭部分信道或全部信道可称之为信道裁剪， 当网络中的部分信 道或全部信道处于关闭状态， 可称该网络处于信道裁剪模式。 例如， 微网 络关闭除导频信道之外的公共物理信道后， 可以称微网络处于信道裁剪模 式。 微网络处于信道裁剪模式后， 不支持终端的初始接入、 和空闲态终端 的驻留， 也不支持不占用专用信道的终端以容量站为目标的小区重选。 由 于， 微网络无法支持终端的初始接入， 即使微网络的信号质量好， 新开机 的终端也无法驻留。 从而， 微网络处于信道裁剪模式后， 在宏基站小区和 微网络同覆盖的情况下， 终端只能驻留在宏网络， 并在宏网络发起数据业 务， 例如寻呼业务和传输业务。 微网络内导频信道处于打开状态， 为终端 提供微网络信号质量的测量服务。
例如， 第三代（3 generation, 3G )通信网络， 如 UMTS网络中， 终端 的状态可以包括 CELL_DCH状态和非 CELL_DCH状态，其中，非 CELL_DCH 状态包括 idle、 URA_PCH、 CELL_PCH和 CELL_FACH等状态。 在本发明实 施例中， CELL_DCH状态， 非 CELL_DCH状态， 以及 idle, URA_PCH, CELL_PCH和 CELL_FACH等状态可以参考 3GPP规范中的描述。 3G网络中， 微网络处于信道裁剪模式后， 无法维护处于非 CELL_DCH状态的终端。 而 CELL_DCH状态的终端分配有专用物理信道和专用传输信道， 终端在专用 信道上进行数据传输， 不需要随机接入， 也不需要读取系统消息， 因此， 微网络处于信道裁剪模式后不会对 CELL_DCH状态的终端的数据业务产生 影响。 因而， 微网络可维护处于 CELL_DCH状态的终端。
例如， 第二代（2 generation, 2G ) 网络或第四代（ 4 generation, 4G ) 网络中终端的状态包括连接态和非连接态。 2G网络或 4G网络中， 微网络针 对非连接优的终端关闭部分公共物理信道进入信道裁剪模式后， 不支持终 端随机接入， 也不发送系统消息， 无法维护处于非连接状态的终端。 微网 络可维护处于连接状态的终端。 本发明实施例中， 2G、 3G、 4G或更高级的 网络制式的网络的划分， 对于本领域技术人员而言， 可以参照通信业界的 共识和经险进行确认。
步骤 12: 若所述终端有微网络业务需求， 所述网络侧通信设备向终端 发送包括微网络配置信息的网络切换指示， 网络切换指示用于指示终端从 宏网络切换到微网络。
终端开机后驻留在宏网络， 在宏网络向宏基站发送业务请求。 在终端 没有业务需求时容量站不维护终端， 在网络侧通信设备监测宏网络中的终 端有微网络业务需求时， 触发终端切入微网络， 由容量站为终端提供业务。 例如， 在 2G网络中， 可由基站控制器（Base Station Controller, 筒称 BSC ) 监测到终端是否有微网络业务需求。在终端有微网络业务需求时， BSC向终 端发送包括微网络配置信息的网络切换指示。 3G网络中可由无线网络控制 器（ Radio Network Controller, 筒称 RNC )监测到终端是否有微网络业务需 求， 在长期演进（Long Term Evolution, LTE )网络系统， 或 LTE高级（LTE Advanced, LTE-A ) 网络系统中， 可以由演进基站（ evolved NodeB , eNB ) 对终端进行检测。 在终端有微网络业务需求时， 宏网络中的网络侧通信设 备向终端发送包括微网络配置信息的网络切换指示。 终端切换到微网络后， 可通过容量站提供的专用信道进行高速度的数据传输。
在本发明实施例中， 可有多种方法监测宏网络中的终端是否有微网络 业务需求， 以下举例说明：
一种方式是， 宏网络中的网络侧通信设备监测所述终端的数据业务量 是否达到业务量门限。 在所述终端的数据业务量达到业务量门限时， 向终 端发送包括所述微网络配置信息的网络切换指示。 其中， 业务量门限可以 根据实际通信状况和通信需求来确定， 也可以根据本领域技术人员的经验 来确定。 例如， 在 3G网络， RNC监测终端的数据业务量是否达到业务量门 限。 在终端的业务量达到业务量门限值时， RNC确定终端有微网络业务需 求。 其中， 业务量门限可以是 3G网络中终端从非 CELL_DCH状态迁移到 CELL_DCH状态时的业务量门限。
另一种实施方式， 宏网络中的网络侧通信设备监测是否接收到所述终 端的业务量通知消息。 业务量通知消息向所述宏网络中的网络侧通信设备 通知所述终端的数据业务量达到业务量门限。 在接收到所述终端的业务量 通知消息时， 所述网络侧通信设备向所述终端发送包括所述微网络配置信 息的网络切换指示。 其中， 业务量门限可以根据实际通信状况和通信需求 来确定， 也可以根据本领域技术人员的经验来确定。 例如， 在 3G网络， 终 端向 RNC发送业务请求时携带网络切换请求， 以请求切入微网络。 RNC监 测到终端的业务请求中携带有网络切换请求时， 确定终端有微网络业务需 求。
又一种实施方式， 宏网络中的网络侧通信设备监测所述终端发送的业 务请求中是否有网络切换请求， 网络切换请求用于请求切入所述微网络。 在所述终端的业务请求中包括网络切换请求时， 网络侧通信设备向所述终 端发送包括所述微网络配置信息的网络切换指示。 终端进入微网络后， 在 专用信道上进行高速率的数据传输。 例如， 在 3G网络， 终端监测自身的业 务量， 在数据业务量达到业务量门限时， 终端向 RNC发送业务量通知消息。
RNC接收到的业务量通知消息后， 确定终端有 £网络业务需求。
另外， 宏网络中的网络侧通信设备也可允许终端在微网络的信号质量 好的情况下从宏网络切换到微网络。 驻留在宏网络内的终端通过微网络的 导频信道测量微网络的信号质量， 在终端测量到微网络的信号质量达到质 量门限值， 向网络侧通信设备上报测量报告。 由于终端位于宏网络和微网 络的同覆盖区。 微网络的信号质量最好， 会达到预设的质量门限值。 网络 侧通信设备确定微网络的信号质量达到质量门限值时， 向终端发送包括微 网络的配置信息的网络切换指示， 指示终端切换到微网络。 终端进入微网 络后， 进行高速率的数据传输。 例如， 在 UMTS网络中， 驻留在宏网络内的 终端转入 CELL_DCH状态后， 终端通过微网络的导频信道测量微网络的信 号质量， 其中， 质量门限值可以根据实际通信状况和通信需求来确定， 也 可根据本领域技术人员的经验来确定。 在终端测量到微网络的信号质量达 到质量门限值， 向 RNC上报测量报告。 由于终端位于宏网络和微网络的同 覆盖区。 微网络的信号质量最好， 会达到预设的质量门限值。 驻留在宏网 络内的终端转入 CELL_DCH状态后， RNC确定微网络的信号质量达到质量 门限值时， 向终端发送包括微网络的配置信息的网络切换指示， 指示终端 切换到微网络的 CELL_DCH状态。 处于 CELL_DCH状态的终端进入微网络 后， 在专用信道上进行高速率的数据传输。
本发明实施例中， 宏网络覆盖范围内有微网络时， 为减少微网络的广 播信令的传输以减少容量站的功耗， 将微网络中除导频信道之外的所有公 共物理信道或部分公共信道关闭， 从而容量站无法支持终端的接入。 终端 在初始接入时从宏网络接入， 当终端有微网络业务需求时， 使终端进入到 微网络， 由微网络为终端提供业务。 由于关闭了微网络中除导频信道之外 的所有公共物理信道或部分公共物理信道， 容量站只在终端有业务需求时 为终端提供高速率的业务， 避免了容量站在终端没有业务需求时也要维护 终端的现象， 避免了容量站不断发射广播信令所产生的开销， 降低了容量 站的功耗， 降低了容量站的发射功率。
图 2为本发明实施例提供的另一种通信方法流程图。 如图 2所示， 本实 施例包括：
步骤 21： 宏网络中的网络侧通信设备监测微网络中的终端是否有微网 络业务需求， 所述微网络在在所述宏网络覆盖范围内， 所述微网络内除导 频信道之外的所有公共物理信道或部分公共物理信道处于关闭状态。
步骤 22: 若所述终端没有微网络业务需求， 所述网络侧通信设备向所 述终端发送网络切换指示或向所述终端发送状态迁移指示， 所述网络切换 指示用于指示所述终端切换到所述宏网络， 状态迁移指用于指示所述终端 迁移到不占用专用信道的状态。
在图 1所示的实施例的方法中， 为节省容量站的无线资源， 可以在步骤 12之后进一步包括图 2所示实施例的步骤 21和步骤 22。
微网络中的终端是指终端接入并驻留在微网络中， 终端在可以在微网 络通过容量站提供的无线资源进行高速率的数据传输。 为不占用容量站提 供的无线资源， 宏网络中的网络侧通信设备监测微网络中终端没有微网络 业务需求时， 指示终端切换到宏网络。 终端进入微网络后， 在专用信道上 进行高速率的数据传输。 由于终端需占用容量站的专用无线资源， 而容量 站维护的无线资源是有限的， 因此监测微网络中的终端是否有微网络业务 需求， 以在终端没有微网络业务需求时使终端切换到宏网络。 或者， 所述 宏网络中的网络侧通信设备还可向终端发送状态迁移指示， 指示终端从占 用专用信道的状态迁移到不占用信道的状态。 处于不占用专用信道的终端 驻留在微网络时， 当需要容量站的维护时， 由于容量站处于信道裁剪模式， 终端会认为微网络质量较差触发小区重选从而进入宏网络驻留。
宏网络中网络侧通信设备可有多种方法确定微网络中的终端是否有微 网络业务需求， 以下举例说明：
一种方式是， 宏网络中网络侧通信设备监测终端的数据业务量是否小 于业务量门限。 在终端的数据业务量小于业务量门限时， 网络侧通信设备 确定终端没有微网络业务需求。 例如， 在 3G网络， RNC监测终端的数据业 务量是否小于业务量门限。 在终端的数据业务量小于业务量门限时， RNC 确定终端没有微网络业务需求。 其中， 业务量门限可以是 3G网络中终端从 CELL_DCH状态迁移到非 CELL_DCH状态时的业务量门限。
另一种方式是， 终端向宏网络中网络侧通信设备发送业务请求时携带 网络切换请求， 以请求切入宏网络。 所述网络侧通信设备监测到终端的业 务请求中携带有网络切换请求时， 确定终端没有微网络业务需求。 例如， 在 3G网络， 终端向 RNC发送业务请求时携带网络切换请求， 以请求切入宏 网络。 RNC监测到终端的业务请求中携带有网络切换请求时， 确定终端没 有微网络业务需求。
又一种实施方式， 终端监测自身的业务量， 在业务量小于业务量门限 时， 向宏网络中网络侧通信设备发送业务量通知消息。 所述网络侧通信设 备接收到的业务量通知消息后， 确定终端没有微网络业务需求。 例如， 在 3G网络， 终端监测自身的业务量， 在业务量小于业务量门限时， 向 RNC发 送业务量通知消息。 RNC接收到的业务量通知消息后， 确定终端没有微网 络业务需求。
本发明实施例宏网络覆盖范围内有受宏基站控制的微网络时， 驻留在 微网络的终端没有微网络业务需求时， 网络侧通信设备指示终端切换到宏 网络， 从而容量站无需维护数据业务量较少的终端， 节省了容量站的无线 资源， 减少了不必要的功率浪费。
图 3A为本发明实施例提供的再一种通信方法流程图。 图 3B为本发明实 施例提供的 Marco网络覆盖范围内有 Pico网络的场景图， Marco网络为 Macro 基站覆盖的网络， Pico网络为 Pico基站覆盖的网络， Pico基站可以由 Marco 基站控制。 如图 3B所示， 在 Pico网络覆盖的范围内， Marco网络和 Pico网络 重叠覆盖， 但 Marco基站的覆盖范围广于 Pico基站的覆盖范围， 宏基站覆盖 范围内可以有众多 Pico基站。
本实施例主要说明在 UMTS网中， Marco网络覆盖范围内有 Pico网络的 场景下， RNC如何对 UMTS网的双模终端进行小区切换， 本实施例中 Pico网 络的同步信道（Synchronization Channel, 筒称 SCH ) 、 公共控制物理信道 ( Common Control Physical Channel, 筒称 CCPCH )、寻呼指示信道 ( Paging Indicator Channel,筒称 PICH )、捕获指示信道 ( Acquisition Indicator Channel, 筒称 AICH ) )和上行随机接入信道 ( Packet Random Access Channel, 筒称 PRACH )处于关闭状态，公共导频信道（ Common Pilot Channel,筒称 CPICH ) 信道处于打开状态。 其中， CCPCH包括主公共控制物理信道 （ Primary Common Control Physical Channel, 筒称 P-CCPCH )和辅助公共控制物理信 道（ Secondary Common Control Physical Channel, 筒称 S-CCPCH )； CPICH 包括： 主寻呼指示信道 ( Primary Paging Indicator Channel, 筒称 P-CPICH ) 和辅助寻呼指示信道 ( Secondary Paging Indicator Channel, 筒称 S-CPICH ) 。
以下先说明 Pico网络关闭上述 UMTS公共物理信道即进入信道剪裁模 式后， 对终端的影响。
首先， 对关闭的各 UMTS公共物理信道的主要作用进行如下说明： SCH 信道主要发送同步消息， 在终端初始接入时， 用于小区搜索和同步小区。 P-CCPCH承载上层广播信道（Broadcast Channel, 筒称 BCH ) , 主要是系 统消息。 S-CCPCH主要承载前向接入信道（Forward Access Channel, 筒称 FACH )和寻呼信道（Paging Channel, 筒称 PCH ) 。 PICH是寻呼指示信道， 传送寻呼指示（ Paging Indicator, 筒称 PI ) 。 Idle、 URA_PCH、 CELL_PCH 的终端，在指定寻呼时机醒来监听 PI。 AICH用于携带网络的捕获指示符号， 该指示符号告知终端通过 PRACH发送的前缀已经被系统检测到， 可以进一 步发送 PRACH消息。 PRACH信道是上行随机接入物理信道， 非 CELL_DCH 状态的终端发起随机接入过程时， 需通过 PRACH信道发 preamble给 UTRAN, 然后去 AICH信道侦听网络的反馈信息。 而打开的信道 P-CPICH是 导频信道， 用于发送小区的主扰码， 是其它各物理信道的功率基准和相位 参考， FDD模式下， 重选或切换时基于该信道对目的小区通过 CPICH进行 信号强度和信号质量的测量。
UMTS网络中的终端状态， 分为 idle、 URA_PCH、 CELL_PCH、 CELL_FACH和 CELL_DCH等状态， 根据各状态终端对 UMTS网络资源的需 求不同， 本发明实施例中将终端的状态分为两大类， CELL_DCH状态和非 CELL_DCH状态， 非 CELL_DCH状态包括 idle、 URA_PCH、 CELL_PCH和 CELL_FACH状态， 即除了 CELL_DCH状态之外的其它各状态。 Pico网络关闭上述 UMTS公共物理信道后，对于非 CELL_DCH状态终端 的影响： SCH信道关闭， 对于新开机的终端， 无法和搜索到的 Pico网络进行 同步， 因此无法在 Pico网络驻留， 继续小区搜索， 检测到 Marco网络信号质 量良好， 因此终端从 Marco网络驻留进去。 PICH信道关闭， 非 CELL-DCH 的终端驻留在 UMTS中， 需要在各自的寻呼时刻周期性醒来侦听 PICH, 看 是否有本组（终端所在的寻呼组） 的寻呼； PICH信道关闭， 非 CELL_DCH 的终端在寻呼时刻去侦听 PICH时， 会找不到 PICH, 因此会认为 Pico网络出 现了问题， 将会触发小区重选； CCPCH信道关闭， P-CCPCH是对系统信息 的承载， 非 CELL_DCH的终端需要读取系统信息， 主要的读取方式有 2种： 一是当系统消息改变的时候， 二是当终端存储的系统消息过期之后， 会自 动重读系统消息； 关闭掉 CCPCH之后， 终端无法获得系统消息， 会认为小 区是故障小区 （barred cell ) , 将触发小区重选。 因此， 当 Pico网络关闭 SCH/CCPCH/PICH/AICH进入信道剪裁模式， 对于终端在 Pico网络的初始接 入、 小区驻留、 测量、 切换和业务的发起等行为会存在相应的影响。
对于 CELL_DCH的终端， 终端分配有专用物理信道、 专用传输信道和 专用逻辑信道。 专用逻辑信道可用专用控制信道 （ Dedicated Control Channel, 筒称 DCCH )和专用业务信道（ Dedicated Traffic Channel, 筒称 DTCH ) , 终端在专用传输信道上进行数据传输， 不需要随机接入， 也不需 要侦听 AICH听取捕获指示（Acquisition Indicator Channel, 筒称 AI ) 。 终端 不需要读取系统消息， 驻留小区的配置信息发生变化时由 RNC通过在专用 信道依次下发各种配置或承载信令， 最后配置给终端， 若 UTRAN需要寻呼 CELL_DCH的终端， 在 DCCH、 专用信道（ Dedicated Channel, 筒称 DCH ) 和专用物理数据信道（Dedicated Physical Control Channel, 筒称 DPDCH ) 上向终端发送 Paging Type2信息 （ Paging Type2信息用于寻呼 CELL_DCH的 终端）， 而不需要侦听 PICH和 CCPCH。 因此 Pico小区进入信道剪裁模式后， 对于 CELL_DCH状态终端的业务收发并不会产生任何影响。 若 CELL_DCH 的终端在服务小区失去同步， 就会变为 CELL_FACH状态。 由上述分析可知 Pico网络进入信道剪裁模式后，无法维护非 CELL_DCH状态的终端， 因此终 端会重选到 Marco网络。
无论 Pico网络是否处于信道剪裁模式， CPICH信道都正常打开， 当有需 要对小区信号质量进行测量时，只需要有 P-CPICH信道支撑即可完成。对于 CELL_DCH的终端的移动性方面， 首先考虑 Pico网络之间的软 /硬切换。 进 行切换之前终端需要对切换的目标小区进行信号质量测量。 UTRAN在 DCCH上下发测量控制 （ Measurement Control ) 消息给 CELL_DCH的终端。 无论目标小区是否处于信道剪裁模式， CPICH信道都正常打开。 CELL_DCH 状态的终端要完成软 /硬切换， 只需要有 P-CPICH信道支撑完成对目标小区 的相关测量即可， 目标小区的网络配置信息由 RNC发送相关配置给需要切 换的 CELL_DCH的终端， 终端拿到目标小区的配置信息之后， 就可以直接 切换， 整个过程不需要目标小区其它物理信道的支撑。 因此， 无论切换的 源小区还是目标小区， 只要保留了 CPICH信道， 能对 CELL_DCH的终端提 供测量支持， 就不会影响终端的切换行为。
如图 3A所示， 本实施例包括：
步骤 1: 终端在 Pico网络开机。
步骤 2: 终端进行小区搜索。
步骤 3： 终端在 Marco网络接入并驻留。
在 Marco网络覆盖范围内有 Pico网络时， Macro网络和 Pico网络互相配置 为邻区， Pico基站关闭 SCH、 CCPCH、 PICH、 AICH、 PRACH信道， 处于 低功耗模式。 当该区域的终端醒来， 进行网络搜索的时候， 因为 Pico网络的 SCH、 CCPCH、 PICH、 AICH、 PRACH信道都处于关闭状态。 由于 Pico网 络的 SCH、 CCPCH、 PICH、 AICH、 PRACH信道都处于关闭状态。 因此 Pico 网络只维护 CELL_DCH状态的终端。 终端即使检测到 Pico网小区信号质量 好，也无法驻留进去，因此终端只能在同覆盖的正常运行的 Macro网络驻留， 并在 Macro网络发起业务。
步骤 4: 在终端的数据业务量达到业务量门限时， 终端向 RNC发送第一 业务量通知消息。
步骤 5： RNC判断终端是否处于 CELL_DCH状态。
RNC接收到终端的第一业务量通知消息时，确定终端有 Pico网络业务需 求， 并判断终端是否处于 CELL_DCH状态。
由于因此 Pico网络只维护 CELL_DCH状态的终端， 因此，终端有敖网络 业务需求且所述终端处于 CELL_DCH状态时， RNC才向所述终端发送包括 Pico网络配置信息的网络切换指示。
步骤 6: 若终端处于非 CELL_DCH状态， RNC向终端发送第二状态迁移 指示， 指示终端迁移到 Macro网的 CELL_DCH状态。
步骤 7: RNC确定终端处于 CELL_DCH状态时， 向终端发送第一测量指 示， 指示终端测量 Pico网络的信号质量。
步骤 8: 终端向 RNC发送第一测量报告， 向 RNC通知 Pico网络的信号质 量达到质量门限值。
由于 Pico网络的 P-CPICH信道正常发送， 所以不会影响终端对 Pico网络 的信号质量测量。
另外， 除步骤 7和步骤 8采用的方案外， RNC也可向终端周期性发送测 量 Pico网络信号质量的测量指示， 在终端测量到 Pico网络的信号质量达到质 量门限值时向 RNC发送测量报告， 由 RNC判决是否对终端驻留小区进行切 换。
步骤 9: RNC向终端发送包括 Pico网络配置信息的网络切换指示， 指示 终端从 Macro网络切换到 Pico网络的 CELL_DCH状态传输业务。
具体地， RNC将 Pico网络的配置信息 (U-RNTI、 RB信息、 无线接入？ 载 ( Radio Access Bearer, 筒称 RAB )信息、 传输层信息和物理层信息)打包， 通过切换命令 ( Handover command ) 下发给终端。 终端根据切换命令内的 Pico区配置， 初始化信令链路、 无线承载（Radio Bearer, 筒称 RB )信息和 传输信道以及物理信道。 终端根据收到的信息元素"允许的最大上行传输功 率 (Maximum allowed UL TX power)" ,执行一个开放环路评估以确定上行链 路发射功率，从 Macro网络的 CELL_DCH状态切换到 Pico网的 CELL_DCH状 态。
步骤 10: 终端切换到 Pico网络， 在 Pico网络进行高速率的数据传输。 步骤 11: 在终端的数据业务量小于业务量门限时， 终端向 RNC发送第 二业务量通知消息， 以向 RNC通知终端的数据业务量小于业务量门限。
终端切换到 Pico网络驻留后， 可周期性测量自身的业务量，在业务量小 于第二业务量门限值时长， 终端向 RNC发送第二业务量通知消息。
步骤 12a: RNC向终端发送第一状态迁移指示， 指示终端从 CELL_DCH 状态迁移到非 CELL_DCH状态。
RNC接收到第二业务量通知消息后， 确定终端已没有 Pico网络业务需 求。 为节省 Pico网络的无线资源， RNC向终端发送第一状态迁移指示。
步骤 13a: 终端从 CELL_DCH状态迁移到非 CELL_DCH状态。
对于迁出 CELL_DCH状态的终端， Pico网络不再对其维护。 当终端在 Pico网络要维持其状态而需要 Pico网络的服务时， 由于 Pico网络处于信道裁 剪模式， 因此终端视 Pico网络质量出现问题，触发小区重选进入 Macro网络。 例如： 当终端周期性读取寻呼消息时， 由于 PICH关闭， 终端周期性读取寻 呼指示消息时找不到 PICH信道， 会认为 Pico网络质量变差， 触发小区重选。
另夕卜， 在步骤 11之后， RNC也可指示终端从 Pico网络切换到 Macro网络 驻留。 可以如下：
步骤 12b: RNC向终端发送包括 Macro网络配置信息的网络切换指示， 指示终端从 Pico网络切换到 Macro网络驻留。 具体地， RNC向终端发送切换到 Macro网络的切换命令， 指示终端从 Pico网络切换到 Macro网络驻留。
步骤 13b: 终端从 Pico网络切换到 Macro网络驻留。
处于 CELL_DCH状态的终端从 Pico网络切换到 Macro网络驻留后， 如果 春数据业务量达到业务量门限值， 重新通过步骤 4至步骤 9切换到 Pico网络。
本发明实施例在 Marco网络覆盖范围内有受宏基站控制的 Pico网络时 上， 为减少 Pico网络的广播信令的传输以减少 Pico的功耗， 将 Pico网络中除 导频信道之外的所有公共物理信道或部分公共信关闭，从而 Pico无法支持非 CELL_DCH状态的终端的接入， 由 Macro网络维护非 CELL_DCH状态的终 端， Pico网络仅可维护 CELL_DCH状态的终端。 终端在初始接入时从 Macro 网络接入，当数据业务量达到业务量门限值时， RNC使终端切入 CELL_DCH 状态并进入 Pico网络的 CELL_DCH状态传输业务，在 Pico网络进行高速率的 数据传输。 进一步， 驻留在 Pico网络的终端的数据业务量减少时， RNC指示 终端迁移到入非 CELL_DCH状态， 或指示终端切入 Macro网络， 从而 Pico网 络无需维护数据业务量较少的终端， 节省了 Pico的无线资源。 由于关闭了 Pico网络中除导频信道之外的所有公共物理信道， 避免了 Pico网络不断发射 广播信令所产生的开销， 降低了 PiC0网络的功耗， 降低了 Pico网络的发射功 率， 从而可以降低邻区干扰， 而且可以获得上、 下行的容量增益。 另外， 由于 Pico网络仅可维护 CELL_DCH状态的终端， 避免了维护非 CELL_DCH 状态的相关信令， 减少了不必要的功率浪费。

可选地， 在切换完成后， 或定时器超时后， 所述网络侧设备可以将所 述载波的所有公共物理信道或部分公共物理信道设置为关闭状态。
在本发明实施例提供的方法中， 在多载波网络中， 例如 UMTS、 LTE或 LTE-A等多载波网络中， 多载波中至少一个载波处于非信道裁剪模式，非信 道裁剪模式为该所有信道处于完整状态， 没有信道处于关闭状态， 所有公 共信道都处于打开状态。 所述多载波中至少一个载波处于信道裁剪模式， 即除导频信道之外的所有公共信道或部分公共信道处于关闭状态。 载波的 信道裁剪模式可以参考本发明上述实施例中关于信道裁剪模式的描述。
在本发明实施例中， 多载波网络中的所有载波在初始状态下可以保持 完整公共信道发射， 即所有载波都是非信道裁剪模式。 在系统运行过程中， 可以根据系统负载、 或激活状态用户数， 或空闲状态用户数等对至少一个 载波设置为信道裁剪模式。 例如， 当系统负载低于预设门限时， 或者激活 状态用户数低于预设数量， 或者空闲状态用户数多于预设数量等， 可以关 闭部分或全部公共信道。例如，在 UMTS多载波网络中，可以根据系统负载、 FACH状态用户数、 或 PCH状态用户数将载波上的所有或部分公共信道关 闭。 进一步， 在本实施例中， 当一个载波被设置为信道裁剪模式后， 还可 以根据系统负载、 或激活状态用户数， 或空闲状态用户数等信息， 将所述 部分或所有的关闭的公共信道打开， 可以将所有关闭的公共信道打开， 也 可以将部分关闭的公共信道打开。 例如， 当系统负载增大、 激活状态的用 户数增加、 或者空闲态的用户数减少时， 可以将所述部分或所有的关闭的 公共信道打开。
在本实施例中， 当终端需要切换到处于信道裁剪模式的载波上时， 例 如， 基站接收到切换指示， 要求将所述终端切换到所述处于信道裁剪模式 的载波时， 可以打开部分或所有被关闭的公共信道， 即基站可以在该载波 上发送完整的公共信道， 或者部分的公共信道。 例如， 相邻基站上的相邻 载波上的终端需要切换到所述处于信道裁剪模式的载波， 或者终端需要当 前基站内的相邻载波切换到所述处于信道裁剪模式的载波， 则基站可以在 所述处于信道裁剪模式的载波上发射完整的公共信道， 或者至少发射主公 共物理控制信道 ( primary-common physical control channel , P-CPCCH )和 SCH。 在本实施例中， 可选地， 当所述终端完成切换后， 可以将所述载波 再重新设置为信道裁剪模式， 例如可以关闭在切换时所述打开的部分或所 有公共信道， 或者可以根据根据系统负载、 或激活状态用户数， 或空闲状 态用户数等信息将所述载波设置为信道裁剪模式。 或者， 也可以设置定时 器， 该定时器可以在原处于关闭状态的公共信道被打开时触发， 当定时器 超时时， 则重新关闭所述打开的公共信道。
