本发明的实施方式
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。
在本发明的实施例中提供了一种无线终端管理的方法，图1是根据本发明实施例的一种无线终端管理方法的流程图，如图1所示，该流程可以包括如下步骤：
步骤S100，无线路由器向无线终端发送确认报文，其中，该确认报文用于确定无线终端是否下线；无线路由器主动向设备管理列表中的无线终端发送确认报文，无线终端在收到该确认报文后向无线路由器进行回复。
步骤S102，无线路由器根据是否接收到无线终端根据该确认报文发送的回复报文确定无线终端是否下线；
上述确认报文可以是无线路由器向终端发送专门的确认报文，也可以是利用无线路由器与终端之间正常的数据交互报文，例如可以是用户通过笔记本电脑无线连上无线路由器观看视频，路由器会一直向笔记本电脑发送视频数据，当笔记本异常下线后，路由器还会继续发送视频数据，而此时终端不会再回复确认报文，在发送一定数目的数据报文之后，无线路由器收不到终端的回复报文，则该无线路由器可以认为终端下线。
步骤S104，在确定无线终端下线的情况下，所述无线路由器剔除所述无线终端。
相关处理无线终端异常下线一般是通过设定固定的老化时间，一定时间不能收到无线终端发来的报文，则认为无线终端设备已经下线。而针对AP管理异常下线STA这个问题，本实施例提供的方法是最直接的一种处理方法。通过主动发送探测报文，如果无线终端没有对该探测报文进行回复，无线路由器可以确定无线终端已经下线，并剔除所述无线终端，可以实现及时监测 到无线终端异常下线并剔除该终端，使之不占用网络资源，不影响其他无线终端上网体验，能够有效管理接入无线路由器的无线终端，给用户带来良好的体验。
在本发明的实施例中还提供了一种无线终端管理的方法，图2是根据本发明实施例的另一种无线终端管理方法的流程图二，如图2所示，该流程可以包括如下步骤：
步骤S200，无线路由器向无线终端发送确认报文，其中，该确认报文用于确定无线终端是否下线；无线路由器主动向设备管理列表中的无线终端发送确认报文，无线终端在收到该确认报文后向无线路由器进行回复。
步骤S202，无线路由器判断是否接收到无线终端根据该确认报文发送的回复报文；在判断结果为是的情况下，执行步骤S204；在判断结果为否的情况下，执行步骤S206。该确认报文可以是无线路由器向终端发送专门的确认报文，也可以是利用无线路由器与终端之间正常的数据交互报文，例如可以是用户通过笔记本电脑无线连上无线路由器观看视频，路由器会一直向笔记本电脑发送视频数据，当笔记本异常下线后，路由器还会继续发送视频数据，而此时终端不会再回复确认报文，在发送一定数目的数据报文之后，无线路由器收不到终端的回复报文，则该无线路由器认为终端下线。
步骤S204，确定该无线终端没有下线，流程结束。
步骤S206，确定该无线终端下线；
步骤S208，在确定无线终端下线的情况下，无线路由器剔除无线终端。
在可选的实施方式中，在判断结果为否的情况下，确定该无线终端下线可以包括：在未收到所述回复报文的情况下，无线路由器启动计数；在计数的结果大于或等于第一阈值的情况下，所述无线路由器确定所述无线终端下线。无线路由器与终端通讯偶尔会出现短暂失连，再迅速连接的情况。为了防止无线路由器误认为无线终端下线，无线路由器在监测到终端没有响应时，启动一个计数器，继续发送确认报文，终端再没有响应时，计数器加1，直至计数值等于或超过预设值。无线路由器此时可以确认无线终端是“真正的下线了”，并将该终端剔除设备管理列表。
在可选的实施方式中，为了防止无线路由器误认为无线终端下线，并剔除该无线终端，在判断结果为否的情况下，确定所述无线终端下线还可以包括：所述未收到所述回复报文的情况下，无线路由器启动计数；在预设时间内获取第一计数的结果和第二计数的结果；计算所述第一计数的结果和所述第二计数的结果的差值；在所述差值大于或等于第二阈值的情况下，所述无线路由器确定所述无线终端下线。无线路由器在启动计数器后，可以在第一个时间点获取第一计数结果，并在第二个时间点获取第二计数结果，第二时间点迟于第一个时间点，计算第二计数结果减去第一计数结果的差值，当所述差值超过阈值时，可以认为无线终端“真正地下线”。还可以采取另外一种方法，无线路由器读取一个时间段内计数值，如果该时间段内的计数值大于或等于第二阈值，也可以认为无线终端“真正地下线”，并将该终端剔除。
可选地，为了使无线路由器更加精确地判断无线终端是否下线，在无线路由器启动计数后，如果在一个时刻收到了终端的响应报文，计数器可以清零。下一次未接收到终端的响应报文，计数器从零开始计数。
在本发明的实施例中还提供了一种无线终端管理的方法，图3是根据本发明实施例的再一种无线终端管理方法的流程图三，如图3所示，该流程可以包括如下步骤：
步骤S300，无线路由器向无线终端发送确认报文，其中，该确认报文用于确定无线终端是否下线；无线路由器主动向设备管理列表中的无线终端发送确认报文，无线终端在收到该确认报文后向无线路由器进行回复。该确认报文可以是无线路由器向终端发送专门的确认报文，也可以是利用无线路由器与终端之间正常的数据交互报文，例如可以是用户通过笔记本电脑无线连上无线路由器观看视频，路由器会一直向笔记本电脑发送视频数据，当笔记本异常下线后，路由器还会继续发送视频数据，而此时终端不会再回复确认报文，在发送一定数目的的数据报文之后，无线路由器收不到终端的回复报文，则该无线路由器认为终端下线。
步骤S302，无线路由器根据是否接收到无线终端根据该确认报文发送的回复报文确定无线终端是否下线；
步骤S304，在确定无线终端下线的情况下，无线路由器向无线终端发送去关联报文；
步骤S306，无线路由器从关联设备列表中删除所述无线终端的信息。
通过本实施例提供的方法，通过采用无线路由器向无线终端发送去关联报文，并删除该无线终端的信息，可以实现及时监测到无线终端异常下线并剔除该终端，使之不占用网络资源，不影响其他无线终端上网体验，能够有效管理接入无线路由器的无线终端，给用户带来良好的体验。
在可选的实施的方式中，无线路由器根据是否接收到所述无线终端根据所述确认报文发送的回复报文确定所述无线终端是否下线包括：无线路由器判断是否接收到无线终端根据所述确认报文发送的回复报文；在判断结果为是的情况下，确定所述无线终端没有下线；和/或，在判断结果为否的情况下，确定所述无线终端下线。
在可选的实施方式中，在判断结果为否的情况下，确定所述无线终端下线包括：在未收到所述回复报文的情况下，所述无线路由器启动计数；在计数的结果大于或等于第一阈值的情况下，所述无线路由器确定所述无线终端下线。
在可选的实施方式中，在判断结果为否的情况下，确定所述无线终端下线还可以包括：在判断结果为否的情况下，确定所述无线终端下线包括：所述未收到所述回复报文的情况下，无线路由器启动计数；在预设时间内获取第一计数的结果和第二计数的结果；计算所述第一计数的结果和所述第二计数的结果的差值；在所述差值大于或等于第二阈值的情况下，所述无线路由器确定所述无线终端下线。

下面再结合具体实施例对本发明进行说明。
实施例一、
本实例提供了一种自动剔除异常下线无线终端的方法，该方法能快速的检测中异常下线的无线终端。主要采用以下技术方案，应用在现有AP设备上，该方法可以包括：
步骤一，无线路由器AP向无线终端STA发送确认报文；其中，STA可以接收该确认报文，并根据确认报文发送一个回复报文至AP。
步骤二，无线路由器AP统计收到STA的回复报文；如果AP没有接收到回复确认报文，则启动计数器；如果AP收到回复报文则计数清零；
步骤三，设定阈值，计数器超过阈值后，无线路由器AP确认STA已经下线；该确认报文可以是无线路由器向终端发送专门的确认报文，也可以是利用无线路由器与终端之间正常的数据交互报文，例如可以是用户通过笔记本电脑无线连上无线路由器观看视频，路由器会一直向笔记本电脑发送视频数据，当笔记本异常下线后，路由器还会继续发送视频数据，而此时终端不 会再回复确认报文，在发送一定数目的数据报文之后，无线路由器收不到终端的回复报文，则该无线路由器认为终端下线。
步骤四，AP剔除该下线的STA。
与相关技术相比较，本实例提供的方法更快速，更灵活。相关处理无线终端异常下线一般是通过设定固定的老化时间，一定时间内收不到无线终端发过来的包，则认为无线终端设备已经下线，一般时间是300秒。实例一通过AP统计没有回复确认包的计数，当计数达到阈值后，检测出STA已经下线，从而能快速剔除STA，消除此STA异常下线给整个无线网络带来的影响。
实施例二、
实例二提供一种自动剔除异常下线无线终端的方法，快速剔除异常下线的无线终端，优化多用户的无线网络，消除对无线局域网中其他终端用户的影响。该方法主要包括如下步骤：
步骤一，对AP每次向STA发包后，对是否收到STA的确认包进行统计，没有收到STA回复，则计数加1；收到STA回复，计数清零；
步骤二，当计数加1后，AP对计数进行判断，若计数超过设定的阈值N，则认为STA已经下线；
步骤三，AP剔除认为下线的STA，向STA发送去关联报文，同时从关联设备列表中删除此STA的信息。
为了更加方便地理解本发明实施例、实例的思想，下面结合具体例子说明。
具体示例一、
步骤一、AP向STA发送确认报文，AP的无线驱动模块可以对STA响应报文进行计数；
步骤二，AP判断是否收到STA的回复报文，没有收到回复报文则计数加1；收到回复报文的计数清零；
步骤三，设定阈值N为200，当计数大于200，即AP向此STA连续发了200个包，此STA都没有回复确认报文，则认为STA已经下线；该确认报文可以是无线路由器向终端发送专门的确认报文，也可以是利用无线路由器与终端之间正常的数据交互报文，例如可以是用户通过笔记本电脑无线连上无线路由器观看视频，路由器会一直向笔记本电脑发送视频数据，当笔记本异常下线后，路由器还会继续发送视频数据，而此时终端不会再回复确认报文，在发送若干数据报文之后而无线路由器收不到终端的回复报文，则该无线路由器可以认为终端下线。
步骤四，AP剔除此STA，向STA发送去关联报文，同时从关联设备列表中删除此STA的信息。
具体示例二：
步骤一，AP向STA发送确认报文，AP的无线驱动模块可以对STA回复报文进行计数；
步骤二，AP的无线驱动模块对每个STA的回复报文进行计数，统计每次AP向STA发包后，是否收到STA的回复报文，没有收到回复报文则计数加1，收到回复报文的计数清零；
步骤三，无线路由器每5秒读取一下计数值，设定阈值N为20，检测周期为5秒。
步骤四，无线路由器判断在检测周期内，计数值是否超过阈值；用当前读到的值减去上一次记录的值，所得差值与阈值进行比较。如果差值大于或等于阈值，无线路由器确认终端下线；如果差值小于阈值，无线路由器确认终端未下线。
步骤五，无线路由器确认无线终端下线；若差值大于阈值20，即5秒内AP向此STA连续发了超过20个包，此STA都没有回复确认报文，则认为STA已经下线；
步骤六，AP剔除此STA，向STA发送去关联报文，同时从关联设备列表中删除此STA的信息。
综上所述，通过上述实施例、可选实施例和实施方式可以看出，本发明实施例是通过统计没有回复确认包的计数，当计数达到阈值后，检测出STA已经下线，从而能快速剔除STA，消除此STA异常下线给整个无线网络带来的影响。采用采用线路由器向无线终端发送确认报文，其中，所述确认报文用于确定所述无线终端是否下线；所述无线路由器根据是否接收到所述无线终端根据所述确认报文发送的回复报文确定所述无线终端是否下线；在确定所述无线终端下线的情况下，所述无线路由器剔除所述无线终端，可以实现及时监测到无线终端异常下线并剔除该终端，使之不占用网络资源，不影响其他无线终端上网体验，能够有效管理接入无线路由器的无线终端，给用户带来良好的体验。
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可选实施例而已，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。
