具体实施方式
通常情况下，现在很多应用发起Wi-Fi扫描，只是为了收集用户周围AP信息，这种频繁的扫描操作，会消耗移动终端的大量功耗。本发明实施例提供了一种无线保真Wi-Fi扫描方法及移动终端，可以降低移动终端的功耗。
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所述附图中的术语“第一”、“第二”、“第三”和“第四”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它步骤或单元。
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展示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。
本发明实施例所描述移动终端可以包括智能手机(如Android手机、iOS手机、Windows Phone手机等)、平板电脑、掌上电脑、笔记本电脑、移动互联网设备(MID，Mobile Internet Devices)或穿戴式设备等，上述仅是举例，而非穷举，包含但不限于上述移动终端。
需要说明的是，在移动终端处于无线保真Wi-Fi连接状态之前，也需要进行Wi-Fi扫描，在其进行Wi-Fi扫描之后，可得到一个Wi-Fi列表，可保存该Wi-Fi列表，通常情况下，该Wi-Fi列表中至少包含1个接入点，及该接入点的接入点信息，接入点信息可包括但不仅限于：接入点名称、接入点的MAC地址、接入点的服务集标识(Service Set Identifier，SSID)、接入点的接入用户数目、接入点的信号强度值等等。移动终端可从该Wi-Fi列表中选择一个接入点，并接入该接入点，从而，实现接入互联网。那么，在移动终端处于无线保真Wi-Fi连接状态时，则可直接获取上次扫描的Wi-Fi列表。
请参阅图1，为本发明实施例提供的一种无线保真Wi-Fi扫描方法的第一实施例流程示意图。本实施例中所描述的无线保真Wi-Fi扫描方法，包括以下步骤：
101、接收由目标应用发起的Wi-Fi扫描请求，所述Wi-Fi扫描请求携带所述目标应用的目标应用标识。
其中，上述目标应用可为可接入互联网的应用，其可包括但不仅限于：地图应用(如：百度地图、Google地图)、即时通讯应用(微信、QQ等)、社交应用(如微博、人人网、Facebook等等)、团购应用(大众点评、美团等)、浏览器应用、支付应用等等。在目标应用发起Wi-Fi扫描时，移动终端的系统接收到该Wi-Fi扫描请求之后，可向Wi-Fi芯片发送扫描指令，该扫描指令指 示Wi-Fi芯片进行扫描，Wi-Fi芯片在接收到扫描指令后，开始进行Wi-Fi扫描。
102、检测所述目标应用标识是否存在于预设标识集合。
其中，预设标识集合可在步骤101之前进行预先设置，预设标识集合中可包含多个应用标识，该应用标识可包括但不仅限于：应用名称、应用版本号、应用开发商、应用的产品日期、应用的类别等等。例如，预设标识集合中可包含多个应用名称，如:预设标识集合可为微信、QQ、手机管家。当然，对于分身应用而言，可将分身应用的一部分设置到预设标识集合，例如，就微信而言，其分身应用为：微信1和微信2，则预设标识集合可只包含微信1或者微信2。
具体地，上述步骤102中，检测所述目标应用标识是否存在于预设标识集合，可按照如下方式实施:
将目标应用标识与预设标识集合中的多个应用标识进行比对，如果目标应用标识与预设标识集合中的某个应用标识一致，则说明目标应用标识存在于预设标识集合。如果目标应用标识与预设标识集合中的任何应用标识一致，则说明目标应用标识不存在于预设标识集合。
103、在所述目标应用标识不存在于所述预设标识集合时，判断当前时间与上次Wi-Fi扫描时间之间的时间差是否大于预设阈值。
其中，预设阈值可由系统默认或者用户自行设置。上次Wi-Fi扫描时间可为上次进行Wi-Fi扫描的扫描时间。上述“上次”可理解为与当前时刻最近的一次。可计算当前时间与上次Wi-Fi扫描时间之间的时间差，如果该时间差大于预设阈值，则执行步骤105，如果该时间差小于或等于预设阈值，则执行步骤104。
可选地，上述步骤102之后，还可以包含如下步骤：
在所述目标应用标识存在于所述预设标识集合时，进行Wi-Fi扫描。
进一步可选地，上述进行Wi-Fi扫描，可包括如下步骤：
A)、确定当前位置；
B)、获取与所述当前位置对应的上次Wi-Fi扫描的扫描结果，所述扫描结果中包含X个接入点，所述X为大于1的整数；
C)、从所述X个接入点中选取Y个目标接入点，所述Y为小于所述X的 正整数；
D)、按照所述Y个目标接入点的稳定性由强到弱的顺序进行扫描。
可选地，上述步骤A中，确定当前位置，可按照如下方式实施：
通过GPS或者Wi-Fi定位技术确定所述当前位置。
其中，移动终端可通过全球定位系统(Global Positioning System，GPS)或者Wi-Fi定位技术确定移动终端的位置
可选地，上述步骤C，从所述X个接入点中选取Y个目标接入点，包括：
筛选出所述X个接入点中符合预设要求的Y个接入点，所述预设要求为接入点的信号强度大于预设信号强度且其密码为静态密码。
可选地，上述步骤C，从所述X个接入点中选取Y个目标接入点，可包括如下步骤：
C1)、根据所述X个接入点的接入点信息对所述X个接入点进行稳定性评价，得到所述X个稳定性评价值；
C2)、从所述X个稳定性评价值中选取大于第一阈值的Y个稳定性评价值对应的所述Y个接入点，所述Y为小于所述X的正整数。
其中，上述C1中可确定每一接入点的稳定性评价值，得到X个稳定性评价值，该稳定性评价值可用于评价每一接入点的稳定性，某一接入点的稳定性评价值越大，则可说明该接入点的稳定性越好。上述第一阈值可由用户自行设置或者系统默认。步骤C2中，可从X个稳定性评价值中选取大于第一阈值的Y个稳定性评价值对应的Y个接入点信息，Y为小于X的正整数。
可选地，上述步骤C1中，根据所述X个接入点的接入点信息对所述X个接入点进行稳定性评价，可按照如下方式实施：
从所述X个接入点的接入点信息中提取稳定性评价指标，得到X个稳定性评价指标集；
根据所述X个稳定性评价指标集对所述X个接入点中的每一接入点进行稳定性评价。
进一步地，所述稳定性评价指标为以下至少一种：接入点的可接入用户数目、接入点的信号强度值、接入点的网络速率和接入点的网络带宽。
其中，可采用至少一个稳定性评价指标对接入点的稳定性进行评价，得到 权重值，其中，稳定性评价指标可包括但不仅限于：接入点的可接入用户数目、接入点的信号强度值、接入点的网络速率、接入点的网络带宽等等。
需要说明的是，由于采用单一稳定性评价指标对接入点的稳定性进行评价时，具有一定的局限性，因此，可采用多个稳定性评价指标对接入点的稳定性进行评价，当然，对接入点的稳定性进行评价时，并非稳定性评价指标越多越好，因为稳定性评价指标越多，稳定性评价过程的计算复杂度越高，也不见得稳定性评价效果越好，因此，在对稳定性评价要求较高的情况下，可采用2～10个稳定性评价指标对接入点的稳定性进行评价。具体地，选取稳定性评价指标的个数及哪个指标，可依据具体实现情况而定。
可选地，在对接入点的稳定性评价精度要求较高的情况下，可以采用多个稳定性评价指标对接入点的稳定性进行评价，在稳定性评价指标对接入点的稳定性进行稳定性评价时，可设置该多个稳定性评价指标中稳定性评价指标的权重，可得到多个稳定性评价值，根据该多个稳定性评价值及其对应的权重可得到最终的稳定性评价值，例如，三个稳定性评价指标分别为：A指标、B指标和C指标，A的权重为a1，B的权重为a2，C的权重为a3，采用A、B和C对某一接入点的稳定性进行评价时，A对应的稳定性评价值为b1，B对应的稳定性评价值为b2，C对应的稳定性评价值为b3，那么，最后的稳定性评价值＝a1b1+a2b2+a3b3。通常情况下，稳定性评价值越大，说明接入点的稳定性越好。
104、在所述当前时间与所述上次Wi-Fi扫描时间之间的时间差小于或等于所述预设阈值，读取所述上次Wi-Fi扫描的扫描结果。
其中，在当前时间与上次Wi-Fi扫描时间之间的时间差小于或等于预设阈值，读取上次Wi-Fi扫描的扫描结果。移动终端可直接读取上次Wi-Fi扫描的扫描结果，即Wi-Fi列表(如图1a，图1a为Wi-Fi列表的一种演示示意图)。移动终端在上次Wi-Fi扫描结束后，可记录扫描时间。
105、在所述当前时间与所述上次Wi-Fi扫描时间之间的时间差大于所述预设阈值，进行Wi-Fi扫描。
其中，在当前时间与上次Wi-Fi扫描时间之间的时间差大于预设阈值，进行Wi-Fi扫描。
例如，移动终端的系统收到应用(如微信、QQ等)发起的Wi-Fi扫描请求，可判断该应用的应用标识是否存在于预设标识集合。如果发起扫描的应用在预设标识集合中，则直接进行Wi-Fi扫描，同时，记录该进行Wi-Fi扫描的扫描时间，假设为：Time_Req。如果发起扫描的应用不在预设标识集合中，则可对比当前时间与上次Wi-Fi扫描时间：
如果current_Time–Req_Time<Threshold，直接返回上一次Wi-Fi扫描的扫描结果。
如果current_Time–Req_Time>Threshold，触发Wi-Fi芯片进行Wi-Fi扫描，同时，可设置Req_Time＝current_time。
其中，上述current_Time为当前时间，Req_Time为上次Wi-Fi扫描的扫描时间，Threshold为预设阈值。
可以看出，通过本发明实施例，接收由目标应用发起的Wi-Fi扫描请求，该Wi-Fi扫描请求携带目标应用的目标应用标识，检测目标应用标识是否存在于预设标识集合，在目标应用标识不存在于预设标识集合时，判断当前时间与上次Wi-Fi扫描时间之间的时间差是否大于预设阈值，在当前时间与上次Wi-Fi扫描时间之间的时间差小于或等于预设阈值，读取上次Wi-Fi扫描的扫描结果，在当前时间与上次Wi-Fi扫描时间之间的时间差大于预设阈值，进行Wi-Fi扫描。从而，可通过预设标识集合降低Wi-Fi扫描的次数，从而，降低移动终端的功耗。
与上述一致地，请参阅图2，为本发明实施例提供的一种无线保真Wi-Fi扫描方法的第二实施例流程示意图。本实施例中所描述的无线保真Wi-Fi扫描方法，包括以下步骤：
201、接收由目标应用发起的Wi-Fi扫描请求，所述Wi-Fi扫描请求携带所述目标应用的目标应用标识。
202、判断移动终端的位置是否存在于历史定位记录中。
其中，移动终端可通过全球定位系统(Global Positioning System，GPS)或者Wi-Fi定位技术确定移动终端的位置。移动终端在每次定位之后，可记录其定位的位置，并将其保存在历史定位记录中，因而，历史定位记录中可至少 包含一个位置。
203、在所述移动终端的位置处于所述历史定位记录中，检测所述目标应用标识是否存在于预设标识集合。
其中，在移动终端的位置处于历史定位记录中，则检测目标应用标识是否存在于预设标识集合。在移动终端的位置处于历史定位记录中，则说明移动终端又来到了以前来过的位置，该位置的范围内可能包含曾经连接过的接入点，因而，可对移动终端的位置进行判断，如果移动终端的位置不存在于历史定位记录，则说明移动终端可能来到一个陌生位置，则可不执行后续步骤。当然，如果移动终端的位置不存在于历史定位记录，也可以不进行Wi-Fi扫描，除非接收到用户输入的扫描指令，则进行Wi-Fi扫描，一方面，为了移动终端的网络安全考虑，另外一方面，也为了降低移动终端的功耗。
204、在所述目标应用标识不存在于所述预设标识集合时，判断当前时间与上次Wi-Fi扫描时间之间的时间差是否大于预设阈值。
205、在所述当前时间与所述上次Wi-Fi扫描时间之间的时间差小于或等于所述预设阈值，读取所述上次Wi-Fi扫描的扫描结果。
206、在所述当前时间与所述上次Wi-Fi扫描时间之间的时间差大于所述预设阈值，进行Wi-Fi扫描。
其中，上述步骤201以及步骤204-步骤206的具体描述可参照图1所描述的无线保真Wi-Fi扫描方法的相应步骤，在此不再赘述。
可以看出，通过本发明实施例，接收由目标应用发起的Wi-Fi扫描请求，该Wi-Fi扫描请求携带目标应用的目标应用标识，在该移动终端的位置存在于历史定位记录中时，则检测目标应用标识是否存在于预设标识集合，在目标应用标识不存在于预设标识集合时，判断当前时间与上次Wi-Fi扫描时间之间的时间差是否大于预设阈值，在当前时间与上次Wi-Fi扫描时间之间的时间差小于或等于预设阈值，读取上次Wi-Fi扫描的扫描结果，在当前时间与上次Wi-Fi扫描时间之间的时间差大于预设阈值，进行Wi-Fi扫描。从而，可通过预设标识集合降低Wi-Fi扫描的次数，从而，降低移动终端的功耗。另外，如果移动终端的位置不存在于历史定位记录则可不执行Wi-Fi扫描，一定程度上可提高移动终端的网络安全性，另外，还可降低移动终端的功耗。
