具体实施方式
下文中将参考附图并结合实施例来详细说明本发明。需要说明的是，在不冲突的情况下，本申请中的实施例及实施例中的特征可以相互组合。
需要说明的是，本发明的说明书和权利要求书及上述附图中的术语“第一”、“第二”等是用于区别类似的对象，而不必用于描述特定的顺序或先后次序。
目前续航能力是衡量产品的一个重要方面，作为一款高性能的Ufi，如果可以在有效支撑其工作的同时最大限度地降低其功耗，将会在很大程 度上提高其续航能力。目前Ufi(下面以AP为例进行说明)的覆盖范围是一个定值，比如是10米，这样如果待接入AP的终端(即，站点STA)位于距离AP 5米的区域内，这样距离AP 5米到10米的区域内的功率覆盖实际上是不必要的，如果可以适当调整AP的覆盖范围，例如调节AP的功率覆盖到6米，则可以在保证终端正常接入的同时，减少6米外的电磁辐射，减少系统广播的开销，从而达到节电绿色的目的。
针对上述方案，在本发明实施例中提出了一种功率的调整方法，图1是根据本发明实施例的功率的调整方法的流程图，如图1所示，该流程包括如下步骤：
步骤S102，确定待接入接入点AP的站点STA与所述AP之间的距离；
步骤S104，根据上述距离调整AP的功率。
其中，执行上述操作的可以是AP，并且，在设置AP的初始功率时，可以将AP的功率设置的偏大一些(例如，可以将AP的功率设置为AP所支持的最大功率)，以保证待接入该AP的终端均位于AP的覆盖范围内。
通过上述步骤，由于可以根据STA和AP的距离调整AP的功率，从而可以确定合理的功率，避免因功率过大而造成的功率浪费。因此，可以解决相关技术中存在的功率浪费的问题，达到节省资源的效果。
在一个可选的实施例中，上述步骤S102可以通过如下方式确定待接入接入点AP的站点STA与AP之间的距离：获取来自STA的接入请求，其中，该接入请求用于请求接入AP，该接入请求中携带有STA发送上述接入请求时的初始功率；确定接收上述接入请求的第一接收功率；根据该初始功率和第一接收功率确定STA与AP之间的距离。在本实施例中，由于STA与AP之间存在一定的距离，因此会存在功率衰减的情况，初始功率与第一接收功率之间会存在衰减，因此，可以利用初始功率与第一接收功率间的衰减来确定STA与AP之间的距离。可选地，可以根据下述公式进行距离的确定：
Los＝32.44+20lgd(Km)+20lgf(MHz)，其中，Los是传输损耗，可 以定义为接收功率(即，上述的第一接收功率)和发射功率(即，上述的初始功率)的比值，d为传输距离，f为发射功率。
在一个可选的实施例中，上述步骤S104可以通过如下方式调整AP的功率：将上述AP的覆盖范围调整成第一覆盖范围，并获取该第一覆盖范围下接收来自STA的接入请求的第二接收功率，其中，该第一覆盖范围的半径(在本实施例中，将AP的覆盖范围类似成一个圆形)比上述距离大第一预定值(该第一预定值大于或等于0)；将AP的覆盖范围调整成第二覆盖范围，并获取上述第二覆盖范围下接收来自STA的接入请求的第三接收功率，其中，该第二覆盖范围的半径比上述距离小第二预定值(该第二预定值大于或等于0)；比较上述第二接收功率和第三接收功率的大小，并根据比较结果确定AP的覆盖范围；根据确定的上述AP的覆盖范围调整AP的功率。在本实施例中，可以先将AP的覆盖范围调成为比上述距离大的一个覆盖范围，而后，再将AP的覆盖范围调整成比上述距离小的一个覆盖范围。需要说明的是，在实际应用中，也可以先将AP的覆盖范围调成为比上述距离小的一个覆盖范围，之后，再将AP的覆盖范围调整成比上述距离大的一个覆盖范围。
在上述实施例中，可以通过如下方式根据上述比较结果调整AP的覆盖范围：当上述比较结果为第二接收功率和第三接收功率相差小于第一差值时(即，两种情况下的覆盖范围对接收功率并未产生明显影响，说明，上述STA与AP的距离不大于第二覆盖范围)，维持上述AP的覆盖范围为第二覆盖范围；和/或，当上述比较结果为第二接收功率和第三接收功率相差大于或等于第一差值(即，两种情况下的覆盖范围对接收功率产生了明显影响，说明，上述STA与AP的距离是大于第二覆盖范围的)，将上述AP的覆盖范围调整为第一覆盖范围。
在一个可选的实施例中，可能会存在对STA与AP之间的距离估计有偏差，例如，通过上述公式计算出来的距离比实际距离偏大，因此，为了确定合理的AP的覆盖范围，需要对估算出来的覆盖范围至少做一次回归(即，至少进行一次缩小确定处理)，即，可能存在两次以上回归的情况， 下面对进行两次以上回归进行说明：在维持上述AP的覆盖范围为第二覆盖范围之后，上述方法还包括：重复执行缩小覆盖范围的操作，直到在缩小后的覆盖范围下接收接入请求的接收功率与缩小之前的覆盖范围下接收接入请求的接收功率相差大于或等于上述第一差值，并确定上述AP的覆盖范围为最后一次缩小之前的覆盖范围；其中，上述缩小覆盖范围的操作包括：缩小AP的覆盖范围；获取缩小后的覆盖范围下接收来自STA的接入请求的接收功率；比较上述AP的覆盖范围缩小前后接入请求的接收功率的大小。
通过以上的实施方式的描述，本领域的技术人员可以清楚地了解到根据上述实施例的方法可借助软件加必需的通用硬件平台的方式来实现，当然也可以通过硬件，但很多情况下前者是更佳的实施方式。基于这样的理解，本发明的技术方案本质上或者说对现有技术做出贡献的部分可以以软件产品的形式体现出来，该计算机软件产品存储在一个存储介质(如ROM/RAM、磁碟、光盘)中，包括若干指令用以使得一台终端设备(可以是手机，计算机，服务器，或者网络设备等)执行本发明各个实施例所述的方法。
在本实施例中还提供了一种功率的调整装置，该装置用于实现上述实施例及优选实施方式，已经进行过说明的不再赘述。如以下所使用的，术语“模块”可以实现预定功能的软件和/或硬件的组合。尽管以下实施例所描述的装置较佳地以软件来实现，但是硬件，或者软件和硬件的组合的实现也是可能并被构想的。

图3是根据本发明实施例的功率的调整装置的确定模块22的结构框图，如图3所示，该确定模块22包括获取单元32、第一确定单元34和第二确定单元36，下面对该确定模块22进行说明：
获取单元32，设置为获取来自STA的接入请求，其中，该接入请求用于请求接入上述AP，该接入请求中携带有上述STA发送上述接入请求时的初始功率；第一确定单元34，连接至上述获取单元32，设置为确定接收上述接入请求的第一接收功率；第二确定单元36，连接至上述第一确定单元34，设置为根据上述初始功率和第一接收功率确定STA与AP之间的距离。
图4是根据本发明实施例的功率的调整装置的调整模块24的结构框图，如图4所示，该调整模块24包括第一处理单元42、第二处理单元44第三确定单元46和调整单元48，下面对该调整模块24进行说明。

图5是根据本发明实施例的功率的调整装置的第三确定单元46的结构框图，如图5所示，该第三确定单元46包括确定子单元52，下面对该确定子单元52进行说明：
确定子单元52，设置为当上述比较结果为第二接收功率和第三接收功率相差小于第一差值时，确定上述AP的覆盖范围为第二覆盖范围；和/ 或，当上述比较结果为第二接收功率和第三接收功率相差大于或等于第一差值，确定上述AP的覆盖范围为第一覆盖范围。
图6是根据本发明实施例的功率的调整装置中调整模块24的优选结构框图，如图6所示，该调整模块24除包括图4所示的所有模块外，还包括第三处理单元62，下面对该第三处理单元62进行说明：
第三处理单元62，连接至上述第三确定单元46，设置为在确定上述AP的覆盖范围为第二覆盖范围之后，进行以下处理：重复执行缩小覆盖范围的操作，直到在缩小后的覆盖范围下接收接入请求的接收功率与缩小之前的覆盖范围下接收接入请求的接收功率相差大于或等于上述第一差值，并确定上述AP的覆盖范围为最后一次缩小之前的覆盖范围；其中，上述缩小覆盖范围的操作包括：缩小AP的覆盖范围；获取缩小后的覆盖范围下接收来自STA的接入请求的接收功率；比较AP的覆盖范围缩小前后接收接入请求的接收功率的大小。
需要说明的是，上述的图2-图6所示的装置均可以应用于AP中，下面以AP为例进行说明：
图7是根据本发明实施例的应用场景示意图，如图7所示，有多个STA待接入AP中。首先对本实施例中的AP的结构进行说明，如图8所示，该AP包括功率-距离量化模块82(对应于上述的确定模块22)、覆盖范围控制模块84、覆盖范围设置模块86(84和86对应于上述的确定单元46)和无线接入信号探测模块88(对应于上述的第一处理模块42和第二处理模块44)，下面结合图9对各模块的功能进行说明：
S1，设备上电开机后，初始化功率-距离量化模块82和无线接入信号探测模块88，对覆盖范围以距离进行量化；
S2，功率-距离量化模块82采集各接入终端(对应于上述的STA)发送的接入请求数据(对应于上述的接入请求)，并对照功率依据距离衰减得出STA至AP的无线距离；(S1和S2对应于图9中的S902)。
S3，覆盖范围控制模块84依据目前收集到的各接入STA的无线距离， 取最远距离对应的覆盖范围，通知覆盖范围设置模块86进行设置；(对应于图9中的S904)
S4，覆盖范围设置模块86开始工作，设置相应覆盖范围后通知无线接入信号探测模块88开始采样；
S5，无线接入信号探测模块88将采样的无线信号发送至覆盖范围控制模块84，由覆盖范围控制模块84进行决策得到覆盖范围的值；
S6，重复S4和S5，得到一个稳定收敛的覆盖范围的值，所得到的数据可发送给功率-距离量化模块82进行备份参考；至此设备的覆盖范围会稳定到一个特定的值，且可以支持现有STA的正常工作，且减少了功率不必要的浪费，从而达到节电的目的。(S4至S6对应于图9中的S906-S918)
下面对上述操作流程进行具体说明：
在本实施例中，能够充分利用AP的功率，减少不必要的功率覆盖，从而达到系统节电的目的。基于终端(对应于上述的STA)接入AP时，AP可以检测并有效评估终端的位置参数；AP侧的覆盖范围以距离进行量化，同一时间内采集比较已接入终端的位置信息；通知覆盖范围设置模块86设置AP的覆盖范围；AP上有特定的应用模块来采集通信现有的终端接入的无线信号探测模块，对现已设定的覆盖范围的效果进行反馈，作为功率调节模块的依据。
其中，评估终端的位置参数假定终端发送接入信息时会携带数据发送的初始功率，这样在AP侧根据收到的信号功率的衰减计算出来STA到AP的无线距离。
STA到AP的距离可以根据无线电磁波在自由空间传播的无线通信距离来大致得出，自由空间中电波传播损耗(亦称衰减)只与工作频率f和传播距离d有关，在自由空间空间传播假定的是一种的理想的传输条件，但是对于近距离传播的估算偏差不会太大，主要是通过以下公式来得出：
Los＝32.44+20lgd(Km)+20lgf(MHz)，其中，Los是传输损耗，可以定义为接收功率和发射功率的比值，d为传输距离，f为发射功率。
AP接收到STA的接入请求，从其中获取到终端的位置参数，之后通知覆盖范围设置模块86设置AP的覆盖范围；假定终端的覆盖范围可提供从2米10米，以2米为间隔的功率覆盖距离，已设定的AP的覆盖范围的合理性和有效性需要通过终端接入信号反馈来判定，在AP处统计接入信号的信号强度，并维护对于每一个STA的信号强度信息，该信号强度信息对功率调节模块提供凭证，直至功率至一个稳定值，为了尽可能减少功率消耗，会对估算出来的覆盖距离至少一次回归，将覆盖范围减少一个间隔，假如估算出来的距离是5米，依据现有的覆盖范围的可设置的值，可以将覆盖范围设置为6米，并记录该STA对应的接入信号强度，接下来将该范围调制4米，并记录该STA的接入信号强度，如果两次信号强度无明显变化，则可继续减少该覆盖范围，如果信号强度衰减较为明显，则调整覆盖范围为增加，回到之前的覆盖范围，说明，该闭环反馈的过程中除了统计信号强度外，显性需要关注的是该STA可以正常接入，并通过该AP进行数据通信，至此该功率调节回路闭合。
基于距离自动调节覆盖范围而达到节电目的的方法切入点是功率的充分利用，为了更好的利用无线功率，可以在设备(对应于上述的AP)上增加硬件天线，提高天线收发效率，设备在开启时会定向扫描现有接入信道的信号，从而大致定位STA，会在接入区域内得到一个扇区和维度分布，最终将各个天线的波束全都集中到STA所在扇区，使功率得到最充分的利用。
通过本发明实施例中所提出的方案能够互补休眠方式对节电的贡献，相关技术中的休眠方式是针对无STA接入时的场景，而本发明实施例是从有STA接入时，结合服务目标的位置对覆盖范围设置一个更合理的值(由于AP的覆盖范围与AP的功率是正相关的，所以可以设置一个合理的功率值)，从而达到节电的目的。
需要说明的是，上述各个模块是可以通过软件或硬件来实现的，对于后者，可以通过以下方式实现，但不限于此：上述模块均位于同一处理器中；或者，上述各个模块以任意组合的形式分别位于不同的处理器中。

可选地，在本实施例中，上述存储介质可以包括但不限于：U盘、只读存储器(Read-Only Memory，简称为ROM)、随机存取存储器(Random Access Memory，简称为RAM)、移动硬盘、磁碟或者光盘等各种可以存储程序代码的介质。
可选地，在本实施例中，处理器根据存储介质中已存储的程序代码执行上述各步骤。
可选地，本实施例中的具体示例可以参考上述实施例及可选实施方式中所描述的示例，本实施例在此不再赘述。
显然，本领域的技术人员应该明白，上述的本发明的各模块或各步骤可以用通用的计算装置来实现，它们可以集中在单个的计算装置上，或者分布在多个计算装置所组成的网络上，可选地，它们可以用计算装置可执行的程序代码来实现，从而，可以将它们存储在存储装置中由计算装置来执行，并且在某些情况下，可以以不同于此处的顺序执行所示出或描述的步骤，或者将它们分别制作成各个集成电路模块，或者将它们中的多个模块或步骤制作成单个集成电路模块来实现。这样，本发明不限制于任何特定的硬件和软件结合。
以上所述仅为本发明的优选实施例而已，并不用于限制本发明，对于本领域的技术人员来说，本发明可以有各种更改和变化。凡在本发明的精神和原则之内，所作的任何修改、等同替换、改进等，均应包含在本发明的保护范围之内。
