具体实施方式
通常情况下，移动终端在用于搜索附近的接入点时，会将Wi-Fi芯片的扫描结果(即Wi-Fi列表)在移动终端的显示屏上进行显示，但是，显示的时间也作为Wi-Fi扫描的扫描时间，该过程需要消耗较长时间，因而，降低了Wi-Fi扫描效率。本发明实施例提供了一种无线保真Wi-Fi扫描方法及相关产品，可以提升Wi-Fi扫描效率。
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。本发明实施例中的移动终端可包含Wi-Fi芯片，该Wi-Fi用于扫描，并获取Wi-Fi列表。
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，其中，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)可作为接入点的标识。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。接入点可由路由器充当、或者，热点(如手机当作热点)充当。
需要说明的是，通常情况下，Wi-Fi在搜索附近的接入点时，在显示Wi-Fi扫描的扫描结果之前，需要等待几秒的扫描时间，因而，会让用户等待一会， 因此，可能会影响到用户体会。通常情况下，Wi-Fi芯片一般都会设置经常接收接入点的beacon帧。本发明实施例中，可通过beacon帧接收确定接入点信息，如此，加速Wi-Fi扫描的上报过程，减少用户等待的时间，本发明实施例中，可按照如下方式实现Wi-Fi扫描：
在目标应用发起Wi-Fi扫描时，向Wi-Fi芯片发送扫描指令，所述扫描指令用于指示所述Wi-Fi芯片进行扫描；
接收由所述Wi-Fi芯片上报的预先存储的N个目标beacon帧，每一所述目标beacon帧对应一个接入点信息，所述N为大于或等于1的整数；
在显示屏上展示由所述N个目标beacon帧对应的接入点信息构成的Wi-Fi列表；
在所述Wi-Fi芯片扫描结束后，得到K个接入点信息，所述K为大于1的整数；
根据所述K个接入点信息完善所述Wi-Fi列表。
如此，在Wi-Fi芯片开始扫描的时候，就开始展示Wi-Fi列表，并在Wi-Fi扫描芯片扫描结束后，完善Wi-Fi列表，如此，可缩短Wi-Fi列表在显示屏上的显示时间。
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、在目标应用发起Wi-Fi扫描时，向Wi-Fi芯片发送扫描指令，所述扫描指令用于指示所述Wi-Fi芯片进行扫描。
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，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、接收由所述Wi-Fi芯片上报的预先存储的N个目标beacon帧，每一 所述目标beacon帧对应一个接入点信息，所述N为大于或等于1的整数。
其中，在Wi-Fi芯片接收到扫描指令之后，一方面可进行Wi-Fi扫描，另一方面，可向上层软件(例如，设置应用、微信、QQ等)发送Wi-Fi芯片上报的预先存储的N个目标beacon帧，该N个目标beacon帧中，每一目标beacon帧可对应一个接入点信息，通常情况下，接入点可按照一定频率向周围广播beacon帧，不同的接入点，其广播的beacon帧不一样，如此，beacon帧可与接入点一一对应。每一接入点广播beacon的广播频率也可以不一样。当然，有的接入点可以不广播beacon帧，具体地，看接入点的设置。
103、在显示屏上展示由所述N个目标beacon帧对应的接入点信息构成的Wi-Fi列表。
其中，上述N个目标beacon对应的接入点信息可构成一个Wi-Fi列表。Wi-Fi列表可包含多个接入点及其对应的接入点信息，如图1a，图1a为Wi-Fi列表的一种演示示意图。
104、在所述Wi-Fi芯片扫描结束后，得到K个接入点信息，所述K为大于1的整数。
其中，在Wi-Fi芯片扫描结束后，其也可以得到一个扫描结果，即K个接入点信息，其中，K为大于1的整数。
105、根据所述K个接入点信息完善所述Wi-Fi列表。
其中，Wi-Fi列表中可能包含上述K个接入点信息中的部分接入点信息，也可以包含除了K个接入点信息之外的接入点信息，因此，需要根据该K个接入点信息完善Wi-Fi列表。
可选地，上述步骤105中，根据所述K个接入点信息完善所述Wi-Fi列表，可包括如下步骤：
51)、将所述K个接入点信息与所述Wi-Fi列表中包含的接入点信息进行比对，得到存在于所述Wi-Fi列表的X个接入点信息和不存在于所述Wi-Fi列表的K-X个接入点信息；
52)、利用所述K-X个接入点信息更新所述Wi-Fi列表。
其中，步骤51可将K个接入点信息与Wi-Fi列表中包含的接入点信息进行比对，例如，如果接入点A的标识在Wi-Fi列表中，则接入点A存在于Wi-Fi 列表中，如果接入点A的标识不在Wi-Fi列表中，则接入点A不存在于Wi-Fi列表中。从而，可得到上述K个接入点信息存在于Wi-Fi列表中的X个接入点信息和不存在于Wi-Fi列表的K-X个接入点信息，从而，保留Wi-Fi列表中的X个接入点信息，并可根据该K-X个接入点信息更新Wi-Fi列表。
可选地，上述步骤105中，根据所述K个接入点信息完善所述Wi-Fi列表，可包括如下步骤：
53)、在所述K个接入点信息中选取信号强度值大于预设阈值的M个接入点信息，所述M为小于所述K的正整数；
54)、将所述M个接入点信息添加到所述Wi-Fi列表。
其中，每个接入点信息中可包含一个信号强度值，用于表示移动终端检测到的接入点的信号强度。上述预设阈值可由系统默认或者用户自行设置。移动终端可从K个接入点信息中选取信号强度值大于预设阈值的M个接入点信息，该M为小于K的正整数，进一步地，可将该M个接入点信息添加到Wi-Fi列表中，并刷新添加之后的Wi-Fi列表。
可选地，上述步骤105中，根据所述K个接入点信息完善所述Wi-Fi列表，可包括如下步骤：
55)、根据所述K个接入点信息对所述K个接入点进行稳定性评价，得到所述K个稳定性评价值；
56)、从所述K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个接入点信息，所述Y为小于所述K的正整数；
57)、根据所述Y个接入点信息更新到所述Wi-Fi列表。
其中，上述55中可确定每一接入点的稳定性评价值，得到K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56中，可从K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K的正整数，只需要根据该Y个接入点信息更新Wi-Fi列表即可，具体地，可参照上述步骤51和步骤52。
可选地，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。
通过本发明实施例，在目标应用发起Wi-Fi扫描时，向Wi-Fi芯片发送扫描指令，该扫描指令用于指示Wi-Fi芯片进行扫描，接收由Wi-Fi芯片上报的预先存储的N个目标beacon帧，每一目标beacon帧对应一个接入点信息，N为大于或等于1的整数，在显示屏上展示由N个目标beacon帧对应的接入点信息构成的Wi-Fi列表，在Wi-Fi芯片扫描结束后，得到K个接入点信息，K为大于1的整数，根据K个接入点信息完善Wi-Fi列表。如此，在Wi-Fi芯片开始扫描的时候，就开始展示Wi-Fi列表，并在Wi-Fi扫描芯片扫描结束后，完善Wi-Fi列表，如此，可缩短Wi-Fi列表在显示屏上的显示时间，提升Wi-Fi扫描效率。
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、在目标应用发起Wi-Fi扫描时，向Wi-Fi芯片发送扫描指令，所述扫描指令用于指示所述Wi-Fi芯片进行扫描。
202、获取当前位置。
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。
203、接收由所述Wi-Fi芯片上报的与所述当前位置对应的预先存储的N个目标beacon帧，每一所述目标beacon帧对应一个接入点信息，所述N为大于或等于1的整数。
其中，只要在Wi-Fi芯片开启的情况下，周围环境中有路由器或者热点，均可以接收到beacon，如此，每一位置接收的beacon帧可不一样，如此，beacon在一定程度上可以反映出位置的不同，例如，用户在公司接收到的beacon帧与在家接收到的beacon不一样。如此，可获取移动终端中预先存储的与当前位置对应的N个目标beacon帧(由于每个位置可能存在不止一个路由器或者热点)。
204、在显示屏上展示由所述N个目标beacon帧对应的接入点信息构成的Wi-Fi列表。
205、在所述Wi-Fi芯片扫描结束后，得到K个接入点信息，所述K为大于1的整数。
206、根据所述K个接入点信息完善所述Wi-Fi列表。
其中，至于上述步骤201-步骤206具体描述可参考图1所描述的无线保真Wi-Fi扫描方法的对应步骤101-步骤105，在此不再赘述。
通过本发明实施例，在目标应用发起Wi-Fi扫描时，向Wi-Fi芯片发送扫描指令，该扫描指令用于指示Wi-Fi芯片进行扫描，接收由Wi-Fi芯片上报的与当前位置对应的预先存储的N个目标beacon帧，每一目标beacon帧对应一个接入点信息，N为大于或等于1的整数，在显示屏上展示由N个目标beacon帧对应的接入点信息构成的Wi-Fi列表，在Wi-Fi芯片扫描结束后，得到K个 接入点信息，K为大于1的整数，根据K个接入点信息完善Wi-Fi列表。如此，由于在Wi-Fi芯片扫描结束之前就展示Wi-Fi列表，因而，加快了Wi-Fi列表的展示速度，因而，可提升Wi-Fi扫描速度。
与上述一致地，请参阅图3，为本发明实施例提供的一种无线保真Wi-Fi扫描方法的第三实施例流程示意图。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：
301、在目标应用发起Wi-Fi扫描时，向Wi-Fi芯片发送扫描指令，所述扫描指令用于指示所述Wi-Fi芯片进行扫描。
302、接收由所述Wi-Fi芯片上报的预先存储的N个目标beacon帧，每一所述目标beacon帧对应一个接入点信息，所述N为大于或等于1的整数。
303、在显示屏上展示由所述N个目标beacon帧对应的接入点信息构成的Wi-Fi列表。
304、在所述Wi-Fi芯片扫描结束后，得到K个接入点信息，所述K为大于1的整数。
305、根据所述K个接入点信息完善所述Wi-Fi列表。
其中，至于上述步骤301-步骤305具体描述可参考图1所描述的无线保真Wi-Fi扫描方法的对应步骤101-步骤105，在此不再赘述。
306、检测所述Wi-Fi列表中是否存在曾成功连接过的目标接入点i，所述目标接入点i为所述Wi-Fi列表中的任一个接入点。
其中，移动终端中可预先保存曾连接过的接入点及其对应的密码，将其与Wi-Fi列表进行比对，如此，可确定Wi-Fi列表中是否存在曾连接过的接入点。
307、在所述Wi-Fi列表中存在所述目标接入点i，与所述目标接入点i建立通信连接。
其中，在Wi-Fi列表中存在曾成功连接过的目标接入点i，则可与其建立通信连接。通常情况下，若是曾连接过的接入点，则可以不进入密码输入，加快了通信连接过程。
通过本发明实施例，在目标应用发起Wi-Fi扫描时，向Wi-Fi芯片发送扫描指令，该扫描指令用于指示Wi-Fi芯片进行扫描，接收由Wi-Fi芯片上报的 与当前位置对应的预先存储的N个目标beacon帧，每一目标beacon帧对应一个接入点信息，N为大于或等于1的整数，在显示屏上展示由N个目标beacon帧对应的接入点信息构成的Wi-Fi列表，在Wi-Fi芯片扫描结束后，得到K个接入点信息，K为大于1的整数，根据K个接入点信息完善Wi-Fi列表，并在Wi-Fi列表中存在曾连接过的接入点时，可接入该接入点。如此，由于在Wi-Fi芯片扫描结束之前就展示Wi-Fi列表，因而，加快了Wi-Fi列表的展示速度，因而，不可提升Wi-Fi扫描速度，而且还可以提升Wi-Fi连接速度。
