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。

图2是本发明实施例公开的另一种无线网络的接入方法的流程示意图；
图3是本发明实施例公开的一种移动终端的单元组成框图；
图4是本发明实施例公开的一种移动终端的结构示意图；
图5是本发明实施例公开的另一种移动终端的结构示意图。
具体实施方式
为了使本技术领域的人员更好地理解本发明方案，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”等是用于区别不同对象，而不是用于描述特定顺序。此外，术语“包括”和“具有”以及它们任何变形，意图在于覆盖不排他的包含。例如包含了一系列步骤或单元的过程、方法、系统、产品或设备没有限定于已列出的步骤或单元，而是可选地还包括没有列出的步骤或单元，或可选地还包括对于这些过程、方法、产品或设备固有的其他步骤或单元。
在本文中提及“实施例”意味着，结合实施例描述的特定特征、结构或特性可以包含在本发明的至少一个实施例中。在说明书中的各个位置出现该短语并不一定均是指相同的实施例，也不是与其它实施例互斥的独立的或备选的实施例。本领域技术人员显式地和隐式地理解的是，本文所描述的实施例可以与其它实施例相结合。
现有技术中，对于手机、平板电脑等移动终端来说，其受限于电池容量的 限制，即便是搭载了超大容量的电池，也面临一天一充电的尴尬局面。现在在手机待机时，若Wi-Fi打开但没有连接路由器，手机上层软件会定时唤醒系统，上层软件自动发起主动扫描命令，底层软件在接收到主动扫描命令后，将主动扫描命令传输到Wi-Fi模块内部，Wi-Fi模块开始主动扫描，主动扫描结束后，将扫描结果上报给软件，通过软件显示出来。上述过程会导致移动终端的功耗增加，续航时间短。
本发明实施例提供的无线网络的接入方法中，移动终端在检测到Wi-Fi模块与当前接入的无线网络断开连接时，确定Wi-Fi模块与无线网络断开连接的原因，生成Wi-Fi断开原因描述信息，并向Wi-Fi模块发送该Wi-Fi断开原因描述信息，通过Wi-Fi模块接收Wi-Fi断开原因描述信息，并通过Wi-Fi模块在判断出Wi-Fi断开原因描述信息与预设Wi-Fi断开原因描述信息匹配时，在第一预设时长范围内接收并记录至少一个信标Beacon帧信号，在检测到上述至少一个信标Beacon帧信号中包括断开连接的无线网络的目标Beacon帧信号时，根据目标Beacon帧信号接入所述无线网络。可见，移动终端与当前接入的无线网络断开连接进行扫描时，无需发送任何的信号，基于接收的目标Beacon帧信号接入无线网络，从而降低移动终端的功耗，延长移动终端的续航时间。
为了更好理解本发明实施例公开的一种无线网络的接入方法及移动终端，下面对本发明实施例进行详细介绍。
请参阅图1，图1是本发明实施例提供的一种无线网络的接入方法的流程示意图，如图1所示，本发明实施例中的无线网络的接入方法包括：
S101、在检测到移动终端的Wi-Fi模块与当前接入的无线网络断开连接时，确定Wi-Fi模块与无线网络断开连接的原因，生成Wi-Fi断开原因描述信息，并向Wi-Fi模块发送所述Wi-Fi断开原因描述信息。
其中，所述在检测到移动终端的Wi-Fi模块与当前接入的无线网络断开连接时，确定Wi-Fi模块与无线网络断开连接的原因之前，所述移动终端还可以执行以下操作：
在检测到所述移动终端的Wi-Fi模块接入无线网络时，获取当前接入的无线网络对应的无线接入点信息，将所述当前接入的无线网络对应的无线接入点 信息添加至预存的无线接入点信息集合中，其中，所述无线接入点信息包括无线接入点对应的Beacon帧信号。
具体地，在检测到所述移动终端的Wi-Fi模块接入无线网络时，获取当前接入的无线网络对应的无线接入点信息，下发一条命令给Wi-Fi模块，以使Wi-Fi模块获取并记录当前接入的无线网络对应的无线接入点信息，并将当前接入的无线网络对应的无线接入点信息添加至预存的无线接入点信息集合中。
S102、通过所述Wi-Fi模块接收所述Wi-Fi断开原因描述信息，并通过所述Wi-Fi模块在判断出所述Wi-Fi断开原因描述信息与预设Wi-Fi断开原因描述信息匹配时，在第一预设时长范围内接收并记录至少一个信标Beacon帧信号。
具体地，若上述预设Wi-Fi断开原因描述信息包括由于beacon timeout导致的断开连接。若上述Wi-Fi断开原因描述信息为用户主动断开无线网络，则上述Wi-Fi断开原因描述信息与预设Wi-Fi断开原因描述信息不匹配，则不执行上述在第一预设时长范围内接收并记录至少一个信标Beacon帧信号的步骤。
其中，所述在第一预设时长范围内接收并记录至少一个信标Beacon帧信号的具体实现方式可以是：当当前信道的信道编号为未处理过的信道编号时，切换至所述当前信道，通过所述Wi-Fi模块在预设时长范围内在所述当前信道接收Beacon帧信号，并在接收到Beacon帧信号时，在预设的Beacon帧信号集合中记录所述接收到的Beacon帧信号，以及在所述预设时长之后根据信道列表更新当前信道的信道编号为未处理过的信道编号。
具体地，移动终端在信道列表(channel list)所列的各个信道之间不断切换，并静候Beacon帧的到来。所收到的任何帧都会被暂存起来，以便取出传送这些帧的基本服务集(basic service set，BSS)的相关数据。在扫描的过程中，工作站会在信道间不断切换，并且会记录收到的任何Beacon的信息。Beacon在设计上是为了让工作站知道加入某个BSS所需要的参数以便进行通信。
S103、在检测到所述至少一个信标Beacon帧信号中包括所述断开连接的 无线网络的目标Beacon帧信号时，根据所述目标Beacon帧信号接入所述无线网络。
这里，所述“断开连接的无线网络”可以是步骤S101中的“当前接入的无线网络”，即最近一次断开的无线网络，也可以是预存的无线接入点信息集合中的任一无线接入点信息对应的无线网络。
其中，所述根据所述目标Beacon帧信号接入所述无线网络的具体实现方式可以是：获取录入的第二接入认证信息；向所述目标Beacon帧信号对应的无线接入点发送所述第二接入认证信息，所述第二接入认证信息用于所述目标Beacon帧信号对应的无线接入点在确认所述移动终端的身份后，将所述移动终端关联至对应的无线网络。
其中，获取录入的第二接入认证信息的具体实现方式可以是：在检测到所述至少一个信标Beacon帧信号中包括所述断开连接的无线网络的目标Beacon帧信号时，显示目标Beacon帧信号对应的无线接入点标识，显示认证信息录入界面，获取用户针对所述认证信息录入界面录入的第二接入认证信息。或者，获取录入的第二接入认证信息的具体实现方式还可以是：在检测到所述至少一个信标Beacon帧信号中包括所述断开连接的无线网络的目标Beacon帧信号时，获取预存的第二接入认证信息。
可选的，所述移动终端还可以执行以下操作：
在检测到所述至少一个信标Beacon帧信号中不包括所述断开连接的无线网络的目标Beacon帧信号时，在第二预设时长范围内发送探测请求Probe Request帧信号；检测是否接收到无线接入点响应所述Probe Request帧而生成的探测响应Probe Response帧；在检测接收到无线接入点响应所述Probe Request帧而生成的探测响应Probe Response帧时，向所述生成Probe Response帧的无线接入点发送第一接入认证信息，所述第一接入认证信息用于所述生成Probe Response帧的无线接入点在确认所述移动终端的身份后，将所述移动终端关联至所述生成Probe Response帧的无线接入点对应的无线网络。
可以看出，本发明实施例提供的无线网络的接入方法中，移动终端在检测到Wi-Fi模块与当前接入的无线网络断开连接时，确定Wi-Fi模块与无线网络 断开连接的原因，生成Wi-Fi断开原因描述信息，并向Wi-Fi模块发送该Wi-Fi断开原因描述信息，通过Wi-Fi模块接收Wi-Fi断开原因描述信息，并通过Wi-Fi模块在判断出Wi-Fi断开原因描述信息与预设Wi-Fi断开原因描述信息匹配时，在第一预设时长范围内接收并记录至少一个信标Beacon帧信号，在检测到上述至少一个信标Beacon帧信号中包括断开连接的无线网络的目标Beacon帧信号时，根据目标Beacon帧信号接入所述无线网络。可见，移动终端与当前接入的无线网络断开连接进行扫描时，无需发送任何的信号，基于接收的目标Beacon帧信号接入无线网络，从而降低移动终端的功耗，延长移动终端的续航时间。
与上述图1所示的实施例一致的，请参阅图2，图2是本发明实施例提供的另一种无线网络的接入方法的流程示意图。如图2所示，本发明实施例中的无线网络的接入方法包括：
S201、在检测到所述移动终端的Wi-Fi模块接入无线网络时，获取当前接入的无线网络对应的无线接入点信息，将所述当前接入的无线网络对应的无线接入点信息添加至预存的无线接入点信息集合中，其中，所述无线接入点信息包括无线接入点对应的Beacon帧信号。
S202、在检测到移动终端的Wi-Fi模块与当前接入的无线网络断开连接时，确定Wi-Fi模块与无线网络断开连接的原因，生成Wi-Fi断开原因描述信息，并向Wi-Fi模块发送所述Wi-Fi断开原因描述信息。
S203、通过所述Wi-Fi模块接收所述Wi-Fi断开原因描述信息，并通过所述Wi-Fi模块在判断出所述Wi-Fi断开原因描述信息与预设Wi-Fi断开原因描述信息匹配时，在第一预设时长范围内接收并记录至少一个信标Beacon帧信号。
其中，在检测到所述至少一个信标Beacon帧信号中包括所述断开连接的无线网络的目标Beacon帧信号时，执行步骤S204至S205；在检测到所述至少一个信标Beacon帧信号中不包括所述断开连接的无线网络的目标Beacon帧信号时，执行步骤S206至步骤S208。
S204、在检测到所述至少一个信标Beacon帧信号中包括所述断开连接的无线网络的目标Beacon帧信号时，获取录入的第二接入认证信息；
S205、向所述目标Beacon帧信号对应的无线接入点发送所述第二接入认证信息，所述第二接入认证信息用于所述目标Beacon帧信号对应的无线接入点在确认所述移动终端的身份后，将所述移动终端关联至对应的无线网络。
S206、在检测到所述至少一个信标Beacon帧信号中不包括所述断开连接的无线网络的目标Beacon帧信号时，在第二预设时长范围内发送探测请求Probe Request帧信号。
S207、检测是否接收到无线接入点响应所述Probe Request帧而生成的探测响应Probe Response帧。
S208、在检测接收到无线接入点响应所述Probe Request帧而生成的探测响应Probe Response帧时，向所述生成Probe Response帧的无线接入点发送第一接入认证信息，所述第一接入认证信息用于所述生成Probe Response帧的无线接入点在确认所述移动终端的身份后，将所述移动终端关联至所述生成Probe Response帧的无线接入点对应的无线网络。
具体地，上述步骤S206至S208为主动扫描过程。即手机(工作站STA)以主动的方式，在每个信道上发出Probe Request帧，请求某个特定无线网络予以回应。主动扫描是主动寻找网络，而不是静候无线网络声明本身的存在。使用主动扫描的工作站将会以如下的程序扫描信道表所列的频道：(1)跳至某个信道，然后等候来帧指示(indicationof an incoming frame)或者等到ProbeDelay定时器超时。如果在这个信道收到帧，就证明该信道有用户在使用，因此可以加以探测。而ProbeDelay定时器可用来防止某个闲置信道让整个过程停止，因为工作站不会一直等待帧的到来。(2)利用基本的DCF访问过程取得媒介使用权，然后送出一个Probe Request帧。(3)至少等候一段最短的信道时间(即MinChannelTime)。a.如果媒介并不忙碌，表示没有网络存在，因此可以跳至下个信道。b.如果在MinChannelTime这段期间媒介非常忙碌，就继续等候一段时间，直到最长的信道时间(即MaxChannelTime)超时，然后处理任何的Probe Response帧。当手机进行WI-FI热点搜索时，有时时间会 比较长，原因是你处在的区域存在多个接入点(AP)，当手机发出Probe Request帧时，多个接入点(AP)通过竞争窗口(congestionwindow)回应Probe Response帧，而这个竞争过程受限于最长的信道时间(即MaxChannelTime)。当无线网络收到搜寻其所属的扩展服务集(ESS)的Probe Request时，就会发出Probe Response帧。若要找到附近所有的无线网络，那么Probe Request帧可使用broadcastSSID，如此一来，该区所有的802.11无线网络都会以Probe Response加以回应。
其中，所述在第一预设时长范围内接收并记录至少一个信标Beacon帧信号，的具体实现方式可以是：
当当前信道的信道编号为未处理过的信道编号时，切换至所述当前信道，通过所述Wi-Fi模块在预设时长范围内在所述当前信道接收Beacon帧信号，并在接收到Beacon帧信号时，在预设的Beacon帧信号集合中记录所述接收到的Beacon帧信号，以及在所述预设时长之后根据信道列表更新当前信道的信道编号为未处理过的信道编号。
可以看出，本发明实施例提供的无线网络的接入方法中，移动终端在检测到Wi-Fi模块与当前接入的无线网络断开连接时，确定Wi-Fi模块与无线网络断开连接的原因，生成Wi-Fi断开原因描述信息，并向Wi-Fi模块发送该Wi-Fi断开原因描述信息，通过Wi-Fi模块接收Wi-Fi断开原因描述信息，并通过Wi-Fi模块在判断出Wi-Fi断开原因描述信息与预设Wi-Fi断开原因描述信息匹配时，在第一预设时长范围内接收并记录至少一个信标Beacon帧信号，在检测到上述至少一个信标Beacon帧信号中包括断开连接的无线网络的目标Beacon帧信号时，根据目标Beacon帧信号接入所述无线网络。可见，移动终端与当前接入的无线网络断开连接进行扫描时，无需发送任何的信号，基于接收的目标Beacon帧信号接入无线网络，从而降低移动终端的功耗，延长移动终端的续航时间。
