为了更清楚地说明本发明实施例中的技术方案， 下面将对实施例描述中 所需要使用的附图作简单地介绍， 显而易见地， 下面描述中的附图仅仅是本 发明的一些实施例， 对于本领域普通技术人员来讲， 在不付出创造性劳动性 的前提下， 还可以根据这些附图获得其他的附图。
图 1是本发明实施例提供的一种控制用户设备的方法流程图；
图 2是本发明实施例提供的另一种控制用户设备的方法流程图； 图 3是用户设备从宏小区移动到 Femtocell时的小区覆盖示意图； 图 4是本发明实施例提供的一种控制用户设备的装置示意图。 具体实施方式
本发明实施例提供一种控制用户设备的方法， 其中， 本发明实施例中目 的小区的基站发射的信号釆用的频点、 扰码与源小区基站发射的信号所釆用 的频点、 扰码相同。 该信号可以是与用户设备源小区基站发射的包括有公共 信道信息的信号同步发射的， 也可以是不同步发射的。 因此， 使得用户设备 接收到目的小区的基站发射的信号， 会认为是源小区基站发射的。 当然用户 设备接收目的小区的基站发射的信号可以在很多场景下， 比如说用户设备从 源小区向目的小区移动的过程中接收到目的小区的基站发射的信号， 具体而 言， 用户设备可以是在源小区内， 也可以已经进入到目的小区内。 目的小区 的基站设备发射的信号中包括的公共信道信息是与源小区的公共信道信息不 同的， 从而使得用户设备可以根据目的小区发射信号中包括的公共信道上承 载的信息获取到目的小区配置的信息， 用户设备根据该目的小区的基站配置 的信息， 执行具体操作。
其中， 不同的目的小区的基站配置的信息不同， 用户设备根据目的小区 的基站配置的信息执行的具体操作也会有不同。 后续实施例中以用户设备的 源小区为宏小区为例， 目的小区以宏小区中 Femtocell覆盖范围所形成的小区 为例， 即目的小区的基站为 Femtocell基站。
本发明实施例还提供相应的装置。 以下分别进行详细说明。
图 1所示为本发明实施例提供的一种控制用户设备的方法流程图。 该方法 运用于包含源小区、 目的小区的通信系统中， 该方法包括： 步骤 SI : 目的小区的基站在第一频点上发射信号， 其中， 该第一频点与 源小区基站发射的信号所使用的频点相同， 发射该信号釆用的扰码与源小区 基站发射的信号所使用的扰码相同， 该信号中寻呼指示信道（PICH, Paging Indicate Channel )和寻呼信道 ( PCH, Paging Channel )上承载有唤醒指定用 户设备的信息； 该信号中的公共信道上还承载该目的小区的基站配置的信息； 目的小区的基站配置的信息用于控制被唤醒的指定用户设备执行相应操作。
其中， 用户设备的源小区具体可以是宏小区； 执行该方法的目的小区的 基站， 具体可以是在宏小区内的家庭基站。 该目的小区中的基站设备在第一 频点上发射的信号， 该第一频点与源小区基站发射的信号所使用的频点相同， 发射该信号釆用的扰码与源小区基站发射的信号所使用的扰码相同， 因此， 使得从源小区向该目的小区移动过程中的用户设备接收到目的小区中基站在 第一频点发射的信号， 将该信号中包括公共信道信息认为是源小区基站发送 的； 用户设备根据对 PICH信道和 PCH中信息的解析， 发现发射该信号的基站 是要寻呼自己， 因此， 用户设备继续从该信号中解析公共信道上承载的目的 小区配置的信息， 用户设备根据获取的目的小区配置的信息， 执行对应的操 作。
需要说明的是， 上述目的小区配置的信息， 可以包括： 第一参数， 用于 指示被唤醒的指定用户设备进行异频测量重选小区的操作， 或者第二参数， 用于指示被唤醒的指定用户设备进行异系统重选的操作， 或者第三参数， 用 于指示被唤醒的指定用户设备进行发起 RRC连接的操作， 或者是其它控制参 数其中任一项或者任意项组合。
例如： 用户设备接收到目的小区基站在第一频点上发射的信号， 其中该 信号包含异频测量门限， 用户设备根据对网络侧的测量结果， 根据异频测量 门限选择进行异频测量重选小区； 或者， 目的小区可以在第一频点上发射的 信号中包含寻呼类型参数， 当用户设备接收到上述寻呼类型参数后， 向目的 小区基站发起无线资源控制 （RRC, Radio Resource Control )连接； 或者， 目 的小区基站在第一频点上发射的信号包含异系统重选参数， 使得当用户设备 接收到异系统重选参数后， 发起异系统重选。
进一步， 在步骤 S1中执行的在第一频点上发射的信号， 可以与宏小区发 射的信号同步， 或者， 也可以不同步。 如果是同步的， 则用户设备接收到步 骤 S1中发射的信号， 可以容易的解析该信号中承载的信息； 如果是不同步的， 则用户设备也可在与该信号进行同步后， 解析该信号中承载的信息。 用户设 备对接收到的步骤 S1中发射的信号的处理属于现有技术。 此处不详述。
该方法还可以包括如下步骤 S2, 步骤 S2只是为了方便理解本发明实施例 技术方案而进行描述， 并非解决本发明技术问题所必要的执行步骤。
步骤 S2: 目的小区的基站在第二频点上发射信号， 其中， 第二频点与用 户设备的源小区基站发射的信号的频点不同。
其中， 该目的小区中的基站执行步骤 S2, 用于在与用户设备的源小区使 用的频点不同的频点上发射信号， 使得该信号覆盖的范围形成的小区为可以 为用户设备提供业务的小区。 目的小区中的基站执行步骤 S2后形成的小区具 体可以是能够提供业务的小区。
当用户设备从源小区向目的小区移动过程中， 用户设备在接收到步骤 S1 中发射的信号， 如果用户设备从公共信道上获取到目的小区配置的信息包括 异频测量门限（如参数 Sintersearch的值）和邻区信息， 其中， 邻区信息至少 包括邻区的扰码号和邻区频点； 且用户设备判断测量的源小区信号质量小于 该异频测量门限时， 用户设备执行异频测量重选小区。 其中， 邻区信息为该 目的小区的基站在第二频点上发射信号所形成的小区 （即目的小区）的信息。
如果用户设备从在第一频点上发射的信号中获取到目的小区配置的信息 是标识用户设备发起 RRC连接的参数， 或者， 目的小区配置的信息是标识用 户设备发起异系统重选的参数， 或者是其它。
通过上述对图 1所示的一种控制用户设备的方法的说明， 目的小区的基站 发射的信号釆用的频点、 扰码与源小区基站发射的信号所釆用的频点、 扰码 相同， 使得从源小区进入到目的小区的用户设备接收到该信号后， 认为该信 号是源小区基站发射的， 且被 PICH和 PCH上承载的信息唤醒， 然后读取该信 号的公共信道上承载目的小区配置的信息， 用户设备根据读取的信息， 执行 相应操作。 由于 PICH和 PCH上承载的信息可以唤醒指定的用户设备， 因此， 使得不同的用户设备， 可以被目的小区的基站唤醒， 执行不同操作， 使得在 不同用户设备可以得到差异化的服务。 这里所说的源小区可以是宏小区。 图 2所示为本发明实施例提供的一种控制用户设备的方法流程图。 在该方 法中以宏小区为源小区为例， Femtocell为目的小区为例。 该方法由 Femtocell 中基站设备执行， 具体可以是家庭基站。
该方法具体包括：
步骤 A1 :在频点 上发射信号，其中，该频点 £2与宏小区使用的频点相同； 该信号釆用的扰码与宏小区基站发射的信号使用的扰码相同； 该信号中 PICH 和 PCH上承载有被唤醒指定用户设备的信息； 该信号中次公共控制物理信道 ( SCCPCH, Subordinate Common Control Physical Channel ) 上 载的寻呼信 道（ PCH, Paging Channel )中包括广播控制信道修改信息（ BCCH modification info ); 该广播控制信道修改信息用来指示被唤醒的指定用户设备读取信号的 主公共控制信道上的信息； 该信号中主公共控制信道（PCCPCH, Principal Common Control Physical Channel ) 上 载的 BCCH上 载的异频测量门限和 邻区信息； 该邻区信息包含目的小区的信息， 该异频测量门限和邻区信息用 于指示被唤醒的指定用户设备进行异频测量重选到邻区信息中指示的目的小 区。
其中， 结合图 3所示的小区示意图， 家庭基站发射的信号釆用的频点、 扰 码与源小区基站发射的信号所釆用的频点、 扰码相同， 使得从宏小区进入到 Femtocell的用户设备接收到家庭基站在频点 £2上发射信号，用户设备从该信号 的扰码和频点认为该信号是宏小区发射的信号。 用户设备读取接收到的信号 中 PICH和 PCH上承载有唤醒指定用户设备的信息， 用户设备判断出宏小区需 要唤醒自己， 因此， 进一步， 该用户设备去 PCH信道上读取信息， 其中， PCH 是逻辑信道，被映射在 SCCPCH上发送给用户设备， 用户设备读取到 PCH上的 信元 BCCH modification info, 用户设备继续执行读取 BCCH上承载的信息， 其 中， BCCH是传输信道， 被映射在 PCCPCH上发送给用户设备。
由于 BCCH上承载的信息中包括在家庭基站预先配置的信息，该配置的信 息用于用户设备在读取都执行异频测量重选该家庭基站所在的 Femtocell为服 务小区， 也可以称异频测量重选目的小区为服务小区。 该配置的信息具体可 以包括： 异频测量门限和邻区信息， 邻区信息具体可以是家庭基站所在的 Femtocell釆用的扰码和频点 （即频点 fl )。 当用户设备读取 BCCH上承载的异 频测量门限（如： 参数 Sintersearch的值）和邻区信息， 判断测量的源小区信 号质量小于该异频测量门限时， 用户设备执行异频测量重选小区。
该方法还可以进一步包括：
步骤 A2: 在频点 fl上发射信号， 其中， 频点 fl与宏小区使用的频点不同。 其中， 家庭基站执行步骤 A2后， 在频点 fl上发射信号所覆盖范围为该 Femtocell真实的可以提供业务的小区， 该家庭基站执行步骤 A1 , 发送的信号 用于引导用户设备进行异频测量重选， 由于用户设备可能已经进入到该 Femtocell的范围内， 因此， 在异频重选的小区时， 会选择驻留到家庭基站在 频点 fl上发射信号所覆盖范围形成 Femtocell中，驻留到该 Femtocell中，也可以 称驻留到目的小区中。
上述是 Femtocell中的家庭基站发射的信号釆用的频点、 扰码与源小区基 站发射的信号所釆用的频点、 扰码相同， 使得从宏小区进入到该 Femtocell中 的指定的用户设备根据 PICH和 PCH上的唤醒该指定用户设备的信息，被唤醒， 进一步，从频点 β上发射的信号中读取公共信道上其它的信息，执行异频测量， 重选小区， 选择驻留到该 Femtocell。
对于从宏小区中进入 Femtocell过程中的特定的用户设备， 还可以根据 Femtocell中家庭基站发射的信号釆用的频点、 扰码与源小区基站发射的信号 所釆用的频点、 扰码相同， 使得用户设备接收到家庭基站发射的信号， 会认 为是宏小区基站发射的信号， 根据 PICH和 PCH上的信息确定该用户设备被唤 醒， 从而用户设备读取该信号中承载的公共信道上的其它信息， 执行例如异 系统重选操作， 或者发起 RRC连接的操作等。 即 Femtocell中家庭基站模仿宏 小区中的设备发射包括有公共信道信息的信号， 控制从宏小区进入到 Femtocell的特定的用户设备， 使得用户设备执行相应操作。 因此， Femtocell 中家庭基站模仿宏小区中的设备发射的信号中包括公共信道信息， 可以参考 现有技术中宏小区发射的包括公共信道信息的信号。 以上图 2是对一种实现控 制的具体说明， 不应该理解为对本发明实施例的现在， Femtocell中家庭基站 中配置的公共信道信息还可以是其它， 实现对用户设备的不同控制， 如异系 统重选， 发起 RRC连接操作等。
图 4所示为本发明实施例提供的一种控制用户设备的装置示意图， 该装置 包括： 第一发射单元 401。
其中， 第一发射单元 401 , 用于在第一频点上发射信号， 其中， 第一频点 与源小区基站发射的信号的频点相同， 发射信号釆用的扰码与源小区基站发 射的信号的扰码相同， 信号中寻呼指示信道和寻呼信道上承载有唤醒指定用 户设备的信息； 所述信号中的公共信道上还承载目的小区的基站配置的信息； 目的小区的基站配置的信息用于控制被唤醒的指定用户设备执行相应操作。
需要说明的是， 上述目的小区配置的信息， 可以包括： 第一参数， 用于 指示被唤醒的指定用户设备进行异频测量重选小区操作， 或者第二参数， 用 于指示被唤醒的指定用户设备进行异系统重选操作， 或者第三参数， 用于指 示被唤醒的指定用户设备进行发起无线资源控制连接操作。
进一步， 该装置还可以包括： 第二发射单元 402, 第二发射单元只是为了 方便理解本发明实施例技术方案而进行描述， 并非解决本发明技术问题所必 要的。
第二发射单元 402, 用于在第二频点上发射信号， 其中， 第二频点与用户 设备源小区基站发射的信号的频点不同， 该信号中承载有公共信道信息。
通过上述对图 1所示的一种控制用户设备的装置的说明， 该装置发射的信 号釆用的频点、 扰码与源小区基站发射的信号所釆用的频点、 扰码相同， 使 得从源小区向目的小区移动过程中的用户设备接收到该信号后， 认为该信号 是源小区基站发射的， 且被 PICH和 PCH上承载的信息唤醒， 然后读取该信号 的公共信道上承载目的小区配置的信息， 用户设备根据读取的信息， 执行相 应操作。 由于 PICH和 PCH上承载的信息可以唤醒指定的用户设备， 因此， 使 得源小区内的不同的用户设备， 有些可以被目的小区的基站唤醒， 执行相应 操作， 使得在同一源小区的不同用户设备可以得到差异化的服务。
进一步， 该装置可以控制在宏小区内用户设备进行异频测量重选小区， 因此， 第一发射单元 401 , 可以具体用于在频点 上发射信号， 其中， 频点 与源小区基站发射的信号的频点相同， 发射信号釆用的扰码与源小区基站发 射的信号的扰码相同， 信号中寻呼指示信道和寻呼信道上承载有唤醒指定用 户设备的信息； 信号中的公共信道上还承载目的小区的基站配置的信息； 目 的小区的基站配置的信息用于控制被唤醒的指定用户设备执行相应操作； 信号中的公共信道上还承载目的小区的基站配置的信息， 具体包括： 信号中次公共控制物理信道上承载的寻呼信道中包括广播控制信道修改 信息， 广播控制信道修改信息用来指示被唤醒的指定用户设备读取信号的主 公共控制信道上的信息； 信号中主公共控制信道上承载的广播控制信道上包 括异频测量门限和邻区信息， 该邻区信息包含目的小区的信息， 异频测量门 限和邻区信息用于指示被唤醒的指定用户设备进行异频测量重选到邻区信息 中指示的目的小区；
第二发射单元 402, 可以具体用于在频点 fl上发射信号， 其中， 频点 fl与 宏小区使用的频点不同， 该信号中承载有第二公共信道信息。
通过上述对该装置的说明， 该装置可以控制用户设备进行小区重选， 且 选择该装置所在的频点 fl发射的信号所覆盖形成的小区（即 Femtocell )为服务 小区。
进一步， 在第一频点上发射信号与宏小区发射的信号同步， 或者， 不同 步。
