无线接入点设备的工作方法及无线接入点设备
本申请要求于 2009 年 10 月 28 日提交中国专利局、 申请号为 200910208507.5、 发明名称为 "无线接入点设备的工作方法及无线接入点 设备" 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
本发明涉及通信领域，尤其涉及一种无线接入点设备的工作方法及无线接 入点设备。 背景技术
由于组网灵活方便， 无线局域网普及程度越来越高。无线局域网由两部分 设备构成： 无线接入点（Access Point, AP)和站点（Stat ion)。 无线 AP下行负 责一定范围内的无线接入信号的覆盖， 在此范围内的各类终端， 如： 电脑、 手 机等可通过站点与无线 AP连接， 访问网络。
现有无线 AP为了保证足够的带宽， 上行是通过以太网或光纤接入因特网 的， 但是随着无线技术， 如： 3G ( 3rd Generation, 第三代移动通信）、 WiMax ( Worldwide Interoperability for Microwave Access, 全球微波互联接入) 的进步， 已经出现上行用 HSPA (High Speed Packet Access, 高速分组接入） 或 WiMax等无线通信制式的无线 AP来替代传统的上行通过以太网和光纤接入 因特网的无线 AP。
这样， 无线 AP的移动性和便携性大大提高，新一代的移动无线 AP已经要 求在室外无外接电源的情况下正常工作， 因而使用电池供电势在必行。
在实现上述用电池向无线 AP供电的过程中， 发明人发现现有技术中至少 存在如下问题：
作为无线 AP， 在两种状态下发射信号， 即无数据传输的空闲状态和有数 据传输的连接状态。 在空闲状态下， AP 需要定期发射广播帧信号， 以便周边 站点可以随时获取本 AP信息， 并进行接入； 在连接状态下， 现有无线 AP都处 在较高的传输速率下， 高的传输速率必然对应着更高阶的调制方式， 必然占用 更多的系统资源， 消耗更多的电量。 总之， 现有技术方案无线 AP的电量消耗 较大， 因而在用电池向其供电时， 无线 AP使用时间较短。 发明内容
本发明的实施例提供一种无线接入点设备的工作方法及无线接入点设备， 能够减少电量消耗， 在用电池供电时， 能够延长使用时间。
为达到上述目的， 本发明的实施例采用如下技术方案：
一种无线接入点设备的工作方法， 包括：
在没有数据连接的情况下， 在 N个广播帧信号使用满功率发射之后， M个 广播帧信号采用低功率发射；
其中， 所述 M为大于 0的整数， 所述 N为大于 1的整数或者 N为大于 0 的整数， 且在一定时间长度内 M与 N的总数保持一定。
一种无线接入点设备， 包括：
功率选择单元， 用于在没有数据连接的情况下，在 N个广播帧信号使用满 功率发射之后， M个广播帧信号采用低功率发射；
其中， 所述 M为大于 0的整数， 所述 N为大于 1的整数或者 N为大于 0 的整数， 且在一定时间长度内 M与 N的总数保持一定。
本发明实施例提供的无线接入点设备的工作方法及无线接入点设备，能够 在没有数据连接的情况下， 在 N个广播帧信号使用满功率发射之后， M个广播 帧信号采用低功率发射。 这样， 本发明实施例提供的无线接入点设备的工作方 法及无线接入点设备， 不像现有的无线接入点设备及其工作方法， 功率放大器 始终在工作， 本发明实施例是使功率放大器间隔工作， 在 N个广播帧信号使用 满功率发射之后， M个广播帧信号采用低功率发射。因而能够减少电量的消耗， 在用电池供电时， 能够延长使用时间。 一种无线接入点设备的工作方法， 包括：
在有数据连接的情况下，以兼容的各种传输速率中最低的传输速率建立数 据连接；
判断当前所述传输速率是否大于等于当前的实际吞吐量加预先设置的系 统参数；如果当前所述传输速率小于所述当前的实际吞吐量加预先设置的系统 参数， 则提高所述传输速率； 如果当前所述传输速率大于等于当前的实际吞吐 量加预先设置的系统参数， 则维持当前传输速率不变。
一种无线接入点设备， 包括：
连接建立单元， 用于在有数据连接的情况下， 以兼容的各种传输速率中最 低的传输速率建立数据连接；
第一判断单元，用于判断当前所述传输速率是否大于等于当前的实际吞吐 量加预先设置的系统参数；
速率提高单元，用于如果当前所述传输速率小于所述当前的实际吞吐量加 预先设置的系统参数， 则提高所述传输速率。
本发明实施例提供的无线接入点设备的工作方法及无线接入点设备，与现 有方法及设备不同， 是以兼容的各种传输速率中最低的传输速率建立数据连 接， 开始工作。 然后， 实时跟踪监测， 判断当前传输速率是否大于等于当前的 实际吞吐量加预先设置的系统参数，如果大于， 则说明当前的传输速率能够满 足用户的使用需求， 传输速率维持不变。 反之， 如果当前传输速率小于当前的 实际吞吐量加预先设置的系统参数，则说明当前的传输速率不能满足用户的使 用需求， 需要提高传输速率。 这样一来， 避免了现有方法及设备大多以高的传 输速率进行传输， 而是以最低传输速率开始工作， 再根据实际的吞吐量随时改 变传输速率，从而避免了更多的使用高阶的调制方式，减少了占用的系统资源， 降低了电量消耗， 在用电池供电时， 能够延长使用时间。 附图说明
为了更清楚地说明本发明实施例或现有技术中的技术方案，下面将对实施 例或现有技术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 出创造性劳动的前提下， 还可以根据这些附图获得其他的附图。

具体实施方式
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， 所描述的实施例仅仅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， 都属于本发明保护的范围。
本发明实施例提供的无线接入点设备的工作方法， 如图 1所示， 该方法步 骤包括： SI 01、在没有数据连接的情况下，在 N个广播帧信号使用满功率发射之后， M个广播帧信号采用低功率发射， 其中， M为大于 0的整数， N为大于 1的整 数或者 N为大于 0的整数， 且在一定时间长度内 M与 N的总数保持一定。
此外，该方法还包括：检测各个站点的接收信号强度指示 RSSI ;根据 RSSI , 动态调整参数 N、 M的值。
具体的，参数 N、M的选择采用接收信号的 RSSI( Rece ived S i gna l St reng th Index , 接收信号强度指示）检测， 来判断被连接的站点设备的距离， 通过统 计的方法估算出站点分布， 进行动态的调整。 例如： 将每一个新站点接收强度 ( RSSI )按照之前设置好的门限 X进行判决， 如果 RSS I>X的站点个数不断增 加， 则 M增加， N减小； 如果 RSSKX的站点个数不断增加， 则 N增加， M减小。 如图 2所示， 图 2中上图为现有 AP的发射情况， 图 2中下图为本实施例的一 种发射情况， 即在某一时刻， 2个信号采用满功率发射， 8个功率采用低功率 发射， 随着新站点的接入， 通过判断新站点接收强度， 本发明实施例提供的工 作方法， 会随实际情况发生变化， 满功率和低功率发射也会相应进行调整。
由本实施例可以明显看出本发明实施例提供的无线接入点设备的工作方 法， 其 AP的发射功率于现有 AP的发射功率的不同。 降低了电量消耗， 延长了 电池的使用时间。
进一步地， 在本发明实施例提供的无线接入点设备的工作方法中， 如图 3 所示， 其步骤还包括：
S30 在有数据连接的情况下， 以兼容的各种传输速率中最低的传输速率 建立数据连接；
S302、判断当前传输速率是否大于等于当前的实际吞吐量加预先设置的系 统参数（这里， 预先设置的系统参数用来表示在实际吞吐量上增加的数据流 量）； 如果当前传输速率小于当前的实际吞吐量加预先设置的系统参数， 则提 高所述传输速率；如果当前传输速率大于等于当前的实际吞吐量加预先设置的 系统参数， 则维持当前传输速率不变。 以兼容的各种传输速率中最低的传输速率建立数据连接，开始工作。然后， 实时跟踪监测，判断当前传输速率是否大于等于当前的实际吞吐量加预先设置 的系统参数， 如果大于， 则说明当前的传输速率能够满足用户的使用需求， 传 输速率维持不变。反之，如果当前传输速率小于当前的实际吞吐量加预先设置 的系统参数， 则说明当前的传输速率不能满足用户的使用需求， 需要提高传输 速率。 这样一来。 避免了现有方法及设备大多以高的传输速率进行传输， 而是 以最低传输速率开始工作，再根据实际的吞吐量随时改变传输速率，从而避免 了更多的使用高阶的调制方式， 减少了占用的系统资源， 降低了电量消耗， 在 用电池供电时， 能够延长使用时间。
进一步地，在上述判断进行之后，还可以判断当前传输速率下的信号强度、 信噪比或者传输的坏包数量是否满足当前传输速率正常工作的要求，如果不能 满足所述当前传输速率正常工作的要求时， 降低所述当前传输速率。此判断与 现有技术相同， 即本发明实施例也兼容了现有技术中的判断方法。
本发明实施例提供的一种无线接入点设备， 如图 4所示， 包括：
功率选择单元 401， 用于在没有数据连接的情况下， 在 N个广播帧信号使 用满功率发射之后， M个广播帧信号采用低功率发射； 其中， M为大于 0的整 数， N为大于 1的整数或者 N为大于 0的整数， 且在一定时间长度内 M与 N 的总数保持一定。
进一步地， 上述无线接入点设备还包括：
调整单元 402， 用于检测各个站点的接收信号强度指示 RSS I ; 根据 RSS I， 动态调整参数 N、 M的值。
这样， 本发明实施例提供的无线接入点设备， 不像现有的无线接入点设备 及其工作方法， 功率放大器始终在工作， 而是使功率放大器间隔工作， 在 N 个广播帧信号使用满功率发射之后， M个广播帧信号采用低功率发射。 因而能 够减少电量的消耗， 在用电池供电时， 能够延长使用时间。
具体的， 在实际应用中， 现有的无线 AP， 如图 5所示， 在无数据连接的 空闲状态下，收发信机 501产生的广播帧信号始终经由功率放大器 502进行放 大后， 再由天线 503发送。
本发明实施例提供的无线接入点设备，功率选择单元 401在实际应用中可 以为两个单刀双掷开关。 具体的， 如图 6所示：
在收发信机 501与功率放大器 502之间设置一个第一单刀双掷开关 601， 该第一单刀双掷开关 601的公共端 601A与收发信机 501的信号输出端电连接， 该第一单刀双掷开关 601的第一选择端 601B与功率放大器 502的信号输入端 电连接。
在功率放大器 502与天线 503之间设置一个第二单刀双掷开关 602， 该第 二单刀双掷开关 602的第一选择端 602B与功率放大器 502的信号输出端电连 接，该第二单刀双掷开关 602的公共端 602A与天线 503通过开关 504电连接。
第一单刀双掷开关 601的第二选择端 601C与第二单刀双掷开关 602的第 二选择端 602C电连接。
这样，通过增加的两个单刀双掷开关，使得收发信机 501和天线 503之间 形成了两条通路， 即从收发信机 501的信号输出端开始， 经第一单刀双掷开关 601的公共端 601A， 再经第一单刀双掷开关 601的第一选择端 601B， 到功率 放大器 502的信号输入端， 经过该功率放大器 502， 从其信号输出端出， 经第 二单刀双掷开关 602的第一选择端 602B， 再经该第二单刀双掷开关 602的公 共端 602A，通过开关 504到达天线 503的通路 1 ; 和从收发信机 501的信号输 出端开始， 经第一单刀双掷开关 601 的公共端 601A， 再经第一单刀双掷开关 601的第二选择端 601C， 到第二单刀双掷开关 602的第二选择端 602C， 再经 该第二单刀双掷开关 602的公共端 602A，通过开关 504到达天线 503的通路 2。
从图 6中可以看出， 通路 1经过功率放大器 502， 而通路 2没有经过功率 放大器 502。 所以收发信机 501产生的广播帧信号既可以由通路 1发出， 也可 以由通路 2发出。 在此， 我们将使用通路 1进行大功率发射称为满功率发射， 将使用通路 2发射称为低功率发射。 进一步地， 上述无线接入点设备， 还可以包括一个与第一单刀双掷开关 601的公共端 601A和第二单刀双掷开关 602的公共端 602A电连接的控制单元 (图中未表示），该控制单元控制第一单刀双掷开关 601的公共端 601A和第二 单刀双掷开关 602的公共端 602A同时接通各自的第一选择端 601B、 602B或者 同时接通各自的第二选择端 601C、 601C。 即， 控制单元可以控制收发信机 501 产生的广播帧信号是经由通路 1发射还是经由通路 2发射。
具体可以为， 控制单元控制第一单刀双掷开关 601 和第二单刀双掷开关 602的公共端 601A、 602A同时接通各自第一选择端 601B、 602B发射 N个广播 帧信号后， 控制第一单刀双掷开关 601 和第二单刀双掷开关 602 的公共端 601A、 602A同时接通各自第二选择端 601C、 602C发送 M个广播帧信号，其中， M为大于 0的整数， N为大于 1的整数或者 N为大于 0的整数， 且在一定时间 长度内 M与 N的总数保持一定。
这样一来， 在无线接入点设备没有数据连接的情况下， 能够将广播帧信号 的发送功率按照一定的间隔比例进行调整，在 N个广播帧信号使用满功率发射 之后， M个广播帧信号采用低功率发射。 因此， 该无线 AP的电流消耗可以大 幅度降低， 延长了电池的使用时间。 在这种发射模式下， 被保留下来的 N个满 功率广播帧信号，可以保证最远端的站点设备能够正确接收到信号并顺利解调 出相关的接入点信息， 并顺利向无线接入点设备发起连接请求， 建立连接。
本发明另一实施例提供的无线接入点设备，功率选择单元 401在实际应用 中可以为一个单刀双掷开关， 例如： 只保留图 6中的第一单刀双掷开关 601， 其中， 第一单刀双掷开关 601的公共端 601A与收发信机 501的信号输出端电 连接， 该第一单刀双掷开关 601的第一选择端 601B与功率放大器 502的信号 输入端电连接， 该第一单刀双掷开关 601的第二选择端 601C直接与收发切换 开关 504和功率放大器 502的信号输出端电连接， 参考图 7 ; 或者， 只保留图 6 中的第二单刀双掷开关 602， 其中， 第二单刀双掷开关 602 的公共端 602A 与收发切换开关 504电连接， 第二单刀双掷开关 602的第一选择端 602B与功 率放大器 502 的信号输出端电连接， 该第二单刀双掷开关 602 的第二选择端 602C直接与收发信机 501和功率放大器 502的信号输入端电连接。 具体的， 如图 Ί所示：
在收发信机 501与功率放大器 502之间设置一个单刀双掷开关 701， 该单 刀双掷开关 701的公共端 701A与收发信机 501的信号输出端电连接， 该单刀 双掷开关 701的第一选择端 701B与功率放大器 502的信号输入端电连接， 该 单刀双掷开关 701的第二选择端 701C与收发切换开关 505电连接。
这样，通过增加单刀双掷开关，使得收发信机 501和天线 503之间形成了 两条通路， 即从收发信机 501的信号输出端开始， 经过单刀双掷开关 701的公 共端 701A， 再经过单刀双掷开关 701的第一选择端 701B， 到功率放大器 502 的信号输入端， 经过该功率放大器 502， 从其信号输出端出， 到达天线 503的 通路 1 ; 和从收发信机 501的信号输出端开始， 经单刀双掷开关 701的公共端 701A,再经单刀双掷开关 701的第二选择端 701C，通过开关 505到达天线 503 的通路 2。
从图 7中可以看出， 通路 1经过功率放大器 502， 而通路 2没有经过功率 放大器 502。 所以收发信机 501产生的广播帧信号既可以由通路 1发出， 也可 以由通路 2发出。 在此， 我们将使用通路 1进行大功率发射称为满功率发射， 将使用通路 2发射称为低功率发射。
进一步地， 上述无线接入点设备， 还可以包括一个与单刀双掷开关 701 电连接的控制单元， 该控制单元控制单刀双掷开关 701的公共端 701A和第一 选择端 701B接通或和第二选择端 701C接通。 即，控制单元可以控制收发信机 501产生的广播帧信号是经由通路 1发射还是经由通路 2发射。
具体可以为， 控制单元控制单刀双掷开关 701的公共端 701A接通第一选 择端 701B发射 N个广播帧信号后，控制单刀双掷开关 701的公共端 701A接通 第二选择端 701C发送 M个广播帧信号， 其中， M为大于 0的整数， N为大于 1 的整数或者 N为大于 0的整数， 且在一定时间长度内 M与 N的总数保持一定。 这样一来， 在无线接入点设备没有数据连接的情况下， 能够将广播帧信号 的发送功率按照一定的间隔比例进行调整，在 N个广播帧信号使用满功率发射 之后， M个广播帧信号采用低功率发射。 因此， 该无线 AP的电流消耗可以大 幅度降低， 延长了电池的使用时间。 在这种发射模式下， 被保留下来的 N个满 功率广播帧信号，可以保证最远端的站点设备能够正确接收到信号并顺利解调 出相关的接入点信息， 并顺利向无线接入点设备发起连接请求， 建立连接。
需要说明的是， 本实施例用一个或两个单刀双掷开关作为功率选择单元 401只是举例说明， 本发明实施例并不限于此， 其他的装置也可以作为功率选 择单元 401， 只要作用相同， 都应该为本发明的保护范围。
进一步地，在本发明又一实施例中，如图 8所示，无线接入点设备还包括： 连接建立单元 801， 用于在有数据连接的情况下， 以兼容的各种传输速率 中最低的传输速率建立数据连接。
第一判断单元 802， 用于判断当前传输速率是否大于等于当前的实际吞吐 量加预先设置的系统参数。
速率提高单元 803， 用于如果当前传输速率小于当前的实际吞吐量加预先 设置的系统参数， 则提高所述传输速率。
这样，避免了现有方法及设备大多以高的传输速率进行传输， 而是以最低 传输速率开始工作，再根据实际的吞吐量随时改变传输速率，从而避免了更多 的使用高阶的调制方式， 减少了占用的系统资源， 降低了电量消耗， 在用电池 供电时， 能够延长使用时间。
此外， 无线接入点设备还包括：
第二判断单元 804， 用于判断当前传输速率下的信号强度、 信噪比或者传 输的坏包数量是否满足当前传输速率正常工作的要求。
速率降低单元 805， 用于如果当前传输速率下的信号强度、 信噪比或者传 输的坏包数量不能满足当前传输速率正常工作的要求时，降低所述当前传输速 率。 判断当前传输速率下的信号强度、信噪比或者传输的坏包数量是否满足当 前传输速率正常工作的要求，如果不能满足所述当前传输速率正常工作的要求 时， 降低所述当前传输速率。 此判断与现有技术相同， 即本发明实施例也兼容 了现有技术中的判断。
本发明实施例提供的无线接入点设备的工作方法， 如图 9所示， 该方法步 骤包括：
S90 在有数据连接的情况下， 以兼容的各种传输速率中最低的传输速率 建立数据连接。
S902、判断当前传输速率是否大于等于当前的实际吞吐量加预先设置的系 统参数； 如果当前传输速率小于当前的实际吞吐量加预先设置的系统参数， 则 提高传输速率；如果当前传输速率大于等于当前的实际吞吐量加预先设置的系 统参数， 则维持当前传输速率不变。
以兼容的各种传输速率中最低的传输速率建立数据连接，开始工作。然后， 实时跟踪监测，判断当前传输速率是否大于等于当前的实际吞吐量加预先设置 的系统参数， 如果大于， 则说明当前的传输速率能够满足用户的使用需求， 传 输速率维持不变。反之，如果当前传输速率小于当前的实际吞吐量加预先设置 的系统参数， 则说明当前的传输速率不能满足用户的使用需求， 需要提高传输 速率。
进一步地， 在上述判断进行之后， 如图 10所示， 该方法步骤还包括： 1001、判断当前传输速率下的信号强度、信噪比或者传输的坏包数量是否 满足当前传输速率正常工作的要求，如果不能满足当前传输速率正常工作的要 求时， 降低当前传输速率。
这样一来。避免了现有方法及设备大多以高的传输速率进行传输， 而是以 最低传输速率开始工作， 再根据实际的吞吐量随时改变传输速率，从而避免了 更多的使用高阶的调制方式， 减少了占用的系统资源， 降低了电量消耗， 在用 电池供电时， 能够延长使用时间。 具体的， 本发明另一实施例提供的无线接入点设备的工作方法， 如图 11 所示， 其步骤包括：
步骤 1101、 无线接入点设备， 在本实施例中可以为无线 AP， 以兼容的各 种传输速率中最低的传输速率建立数据连接。
步骤 1102、 无线 AP以当前的传输速率进行数据传输。
步骤 1103、 判断数据传输过程是否完成， 如果完成则结束数据传输。 步骤 1 104、 当数据传输尚未完成时， 判断当前传输速率是否大于等于当 前的实际吞吐量加预先设置的系统参数。
步骤 1 105、 如果判断结果为当前传输速率小于当前的实际吞吐量加预先 设置的系统参数， 即当前的传输速率不能满足用户的需求， 则提高数据传输速 率。
步骤 1106、 如果步骤 11 04确定当前传输速率是大于等于当前的实际吞吐 量加预先设置的系统参数， 即当前的传输速率能够满足用户的需求， 则判断当 前传输速率下的信号强度、信噪比或者传输的坏包数量是否满足当前传输速率 的要求， 如果满足， 则继续以该速率传输。
或者， 如果步骤 1 104确定当前传输速率小于当前的实际吞吐量加预先设 置的系统参数， 即当前的传输速率不能足用户的需求， 则判断经过步骤 1105 提高后的传输速率下的信号强度、信噪比或者传输的坏包数量是否满足当前传 输速率的要求， 如果满足， 则继续以该速率传输。
步骤 1107、 当步骤 1106判断出为不能满足时， 则降低当前的传输速率， 并以降低后的速率进行传输。
本实施例提供的无线 AP的工作方法， 不仅兼容了现有的判断方法， 而且 以兼容的各种传输速率中最低的传输速率建立数据连接， 开始工作。 然后， 实 时跟踪监测，判断当前传输速率是否大于等于当前的实际吞吐量加预先设置的 系统参数， 如果大于， 则说明当前的传输速率能够满足用户的使用需求， 传输 速率维持不变。反之，如果当前传输速率小于当前的实际吞吐量加预先设置的 系统参数， 则说明当前的传输速率不能满足用户的使用需求， 需要提高传输速 率。 这样一来。 避免了现有方法及设备大多以高的传输速率进行传输， 而是以 最低传输速率开始工作， 再根据实际的吞吐量随时改变传输速率，从而避免了 更多的使用高阶的调制方式， 减少了占用的系统资源， 降低了电量消耗， 在用 电池供电时， 能够延长使用时间。
