Description

信号探测方法、 微基站开启方法和相关设备及系统 本申请要求于 2012 年 12 月 14 日提交中国专利局、 申请号为 201210546694.X, 发明名称为 "信号探测方法、 微基站开启方法和相关设备及 系统"的中国专利申请的优先权， 其全部内容通过引用结合在本申请中。 技术领域
本发明涉及通信技术领域中的微基站技术领域，尤其涉及一种信号探测方 法、 微基站开启方法和相关设备及系统。
背景技术
移动通信网络中， 由于业务分布时域和地域的差异， 在进行网络覆盖时， 通常会出现宏基站和微基站共同覆盖的情形，例如，一个宏基站覆盖的区域中， 可以部署多个微基站，且宏基站和微基站支持的网络制式可以相同，也可以不 同。
在实际应用中， 当宏基站下的业务量较小时， 只需要宏基站即可以对其覆 盖区域内的用户终端进行服务， 此时为了节省微基站能耗， 可以将该宏基站覆 盖区域中的微基站关闭； 当业务量增加， 并超出该宏基站的处理容量时， 可以 选择性开启该宏基站覆盖区域中的多个微基站中一个或几个。
目前，现有技术中如何开启微基站的方案， 主要是基于用户终端侧探测的 方案， 具体如下：
首先， 预先为微基站设置三种状态， 一种为休眠状态， 此时微基站停止射 频发射，在处于休眠状态时微基站不会为用户终端的通信提供服务， 即属于未 开启状态； 第二种为待探测状态， 此时微基站发送下行信号， 如导频信号、 参 考信号或广播信号， 以供用户终端探测，在处于待探测状态时微基站也不会为 用户终端的通信提供服务， 即也属于未开启状态； 第三种为开启运行状态， 此 时微基站为用户终端的通信提供服务， 即属于开启状态。 当宏基站业务量超过某个门限时，宏基站指示归属自身的各微基站进入待 探测状态； 各微基站在接收到指示后， 进入待探测状态， 即发送下行信号； 同 时，宏基站向归属自身的用户终端发送测量指示，指示用户终端测量各微基站 发送的下行信号； 用户终端在接收到测量指示后，对各微基站发送的下行信号 进行测量， 并将测量结果上报给宏基站， 例如， 将测量到的微基站的基站标识 上报给宏基站； 宏基站根据用户终端上报的测量结果，从多个微基站中选择性 开启一个或几个微基站。 然而， 在上述如何开启微基站的方案中， 微基站在进入待探测状态时， 需 要开启自身的射频发射模块以发送下行信号， 用于用户终端进行测量，从而增 加了微基站的功耗； 且对于微基站处于待探测状态的时间较难确定， 太长， 则 增加了微基站的功耗， 太短， 则由于进行测量的用户终端能力的限制， 使得测 量结果不够准确； 并且， 在进行测量时， 需要宏基站下的所有用户终端都对微 基站发送的下行信号进行测量， 对用户终端当前进行的业务造成了一定的影 响， 如使得数据下载速率降低等， 并且增加了用户终端的耗电量。
发明内容

下面结合附图， 用具体实施例对本发明提供的方法、相关设备及系统进行 详细描述。
实施例 1 :
本发明实施例 1 中， 对如何确定是否开启微基站的处理流程进行详细描 述， 如图 3所示， 具体包括如下处理步骤：
步骤 301、 宏基站在根据自身当前的业务量确定需要开启微基站时， 向归 属自身的当前处于休眠状态的各微基站发送进入探测状态的探测指示消息，用 于指示微基站进入探测状态。
步骤 302、 宏基站向微基站发送待探测用户终端的终端标识， 用于指示微 基站针对待探测用户终端进行探测。其中，待探测用户终端可以为当前接入宏 基站的所有用户终端。
进一步的， 本步骤中，宏基站还可以向微基站发送待探测用户终端使用的 物理资源块信息， 以及待探测用户终端的同步信息。 其中， 每个待探测用户终 端使用的物理资源块信息， 以及该待探测用户终端的同步信息， 可以是与该探 测用户终端的终端标识对应的。 该物理资源块信息的表征形式可以随网络制式的不同而不同， 例如，对于 全球移动通讯系统（Global System of Mobile communication, GSM ) 网给， 可 以通过频点、 时隙和跳频等参数表征物理资源块信息， 对于宽带码分多址 ( Wideband Code Division Multiple Access, WCDMA ) 网络， 可以通过频点、 扰码及解调参数表征物理资源块信息， 对于长期演进（Long Term Evolution, LTE ) 网络， 可以通过频段、 子载波和时隙表征物理资源块信息。
本步骤与上述步骤 301中向 基站发送的信息，可以同时一次性发送给各 微基站， 也可以分次发送给各微基站。
步骤 303、 微基站在接收到宏基站发送的探测指示消息后， 触发自身进入 探测状态， 在进入探测状态之后， 微基站将执行后续步骤 304和步骤 305。
步骤 304、 基站探测用户终端发送的上行信号。
当微基站接收到宏基站发送的待探测用户终端的终端标识，则具体可以基 于待探测用户终端的终端标识， 探测所述待探测用户终端发送的上行信号。
进一步的，当微基站还接收到宏基站发送的待探测用户终端使用的物理资 源块信息， 以及待探测用户终端的同步信息时， 则具体可以基于待探测用户终 端的终端标识和待探测用户终端的同步信息，探测待探测用户终端对应使用的 物理资源块信息对应的物理资源块发送的上行信号。
基于待探测用户终端的终端标， 同步信息， 以及对应使用的物理资源块信 息，对待探测用户终端发送的上行信号进行探测， 能够使得微基站在探测时更 有针对性， 从而能够更有效的进行探测， 进而达到控制功耗的目的。
本步骤中，微基站在探测上行信号时， 具体还可以探测用户终端发送的上 行信号的信号强度。
其中， 所探测的上行信号的信号强度， 可以为现有技术中的各种上行信号 的信号强度， 且表征形式可以随网络制式的不同而不同， 例如， 可以为接收信 号电平 （Received Signal Level, Rxlev ), 也可以为接收信号码功率（Received Signal Code Power, RSCP ), 也可以为参考信号接收功率 （Reference Signal Receiving Power, RSRP)。
步骤 305、 微基站将探测到的用户终端的终端标识发送给自身归属的宏基 站。
进一步的，还可以将与终端标识对应的信号强度， 即探测到的用户终端发 送的上行信号的信号强度发送给宏基站。
步骤 306、 宏基站在接收到微基站发送的探测结果之后， 即可以基于探测 结果确定是否开启该微基站， 具体可以采用如下方式：
第一种方式：当微基站发送的探测结果中包括探测到的用户终端的终端标 识时，宏基站可以根据接收的微基站探测到的用户终端的终端标识的数量， 确 定是否开启该微基站， 例如， 当数量大于第一预设数量阈值时， 确定开启， 否 贝' J , 确定不开启。
第二种方式：当微基站发送的探测结果中包括探测到的用户终端的终端标 识， 以及对应的探测到的用户终端发送的上行信号的信号强度时，宏基站可以 根据微基站探测到的用户终端的终端标识中，对应的信号强度大于预设强度阈 值的终端标识的数量， 确定是否开启该微基站， 例如， 当数量大于第二预设数 量阈值时， 确定开启， 否则， 确定不开启。
上述第一种方式和第二种方式， 均是仅根据一个微基站发送的探测结果， 确定该微基站是否开启， 本发明实施例中，也可以根据多个微基站发送的探测 结果， 从多个微基站中选择一个或多个微基站开启。
第三种方式： 宏基站可以依次针对多个微基站中的每个微基站，确定是否 开启该微基站， 其中， 多个微基站的确定顺序， 可以是随机的， 也可以是按照 各自探测到的用户终端的终端标识的数量从高到低的顺序。
针对当前待判断是否开启的微基站，当微基站发送的探测结果中包括探测 到的用户终端的终端标识时，宏基站可以先确定该微基站探测到的用户终端的 终端标识中， 除已确定开启的微基站发送的探测到的用户终端的终端标识之 夕卜， 剩余的终端标识的数量， 并根据该剩余的终端标识的数量， 确定是否开启 该微基站， 例如， 当数量大于第三预设数量阈值时， 确定开启， 否则， 确定不 开启。
第四种方式： 宏基站可以依次针对多个微基站中的每个微基站，确定是否 开启该微基站， 其中， 多个微基站的确定顺序， 可以是随机的， 也可以是按照 各自探测到的用户终端的终端标识的数量从高到低的顺序。
针对当前待判断是否开启的微基站，当微基站发送的探测结果中包括探测 到的用户终端的终端标识，以及对应的探测到的用户终端发送的上行信号的信 号强度时，宏基站可以先确定该微基站探测到的用户终端的终端标识中， 除已 确定开启的微基站发送的探测到的用户终端的终端标识之外， 剩余的终端标 识， 并根据该剩余的终端标识中，对应的信号强度大于预设强度阈值的终端标 识的数量，确定是否开启该该微基站，例如， 当数量大于第二预设数量阈值时， 确定开启， 否则， 确定不开启。
步骤 307、 宏基站向确定开启的微基站发送开启指示消息， 向确定不开启 的微基站发送休眠指示消息。
步骤 308、 微基站在接收到宏基站发送的开启指示消息之后， 触发自身进 入开启运行状态， 为用户终端的通信提供服务， 以分担宏基站的业务量。
微基站在接收到宏基站发送的休眠指示消息之后， 触发自身进入休眠状 态。
采用本发明实施例 1提供的上述方案，在确定是否开启宏基站下的微基站 时，微基站不需要启动射频发射模块发送下行信号， 只需要探测用户终端发送 的上行信号，相比发送下行信号，探测用户终端发送的上行信号所需要功耗较 少， 从而减少了微基站的功耗。
并且，在这一过程中，不需要用户终端的参与，即节省了用户终端的功耗， 且避免了对用户终端当前所进行业务的业务质量的影响。
并且， 微基站的探测能力相比用户终端要高， 所以， 又微基站对用户终端 发送的上行信号进行探测，相比用户终端探测微基站发送的下行信号， 所得到 的探测结果更准确，从而使得后续宏基站基于探测结果所确定是否开启微基站 的结果也更准确。
