具体实施方式
为使本发明实施例的目的、技术方案和优点更加清楚，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。
图1为本发明通信连接的控制方法实施例一的流程示意图；图2为本发明通信连接的控制方法实施例一的应用场景示意图。如图1和图2所示，Wi-Fi接入点1和Wi-Fi接入点2的覆盖区域分别为区域1和区域2，而区域 1、区域2之间存在重叠区域S，当具有Wi-Fi功能的设备，如手机、iPad等于位置A时，设备仅搜索到Wi-Fi接入点1的信号，也就是说，仅搜索到一个可选Wi-Fi接入点，即为Wi-Fi接入点1，则设备自动向Wi-Fi接入点1发起连接请求；当设备位于位置B时，此时设备除了可搜索到当前连接的Wi-Fi接入点1的信号以外，还可搜索到Wi-Fi接入点2的信号，故此时设备搜索到两个可选Wi-Fi接入点，为了及时获取质量较优的通信服务质量，本实施例依照下述各步骤，控制设备与可选Wi-Fi接入点之间的通信连接：
S101、设备在搜索到的至少一个可选Wi-Fi接入点中确定最优Wi-Fi接入点。
具体的，设备可按照预设方法，在搜索到的至少一个可选无线保真Wi-Fi接入点中确定最优Wi-Fi接入点，上述预设方法可以为网络速度选择法、信号强度选择法等；详细来说，网络速度选择法即为在搜索到的至少一个可选无线保真Wi-Fi接入点中，选择提供的网络速度最高的Wi-Fi接入点为最优Wi-Fi接入点；而信号强度选择法即为在搜索到的至少一个可选无线保真Wi-Fi接入点中，选择信号强度最强的Wi-Fi接入点为最优Wi-Fi接入点。
具体的，设备在搜索到某个Wi-Fi接入点的信号时，会获取该Wi-Fi接入点的标识，例如SSID(Service Set Identifier,服务集标识)、协议信息、信号强度、网络速度等，以信号强度选择法为上述预设方法示例，设备可获知各个可选Wi-Fi接入点的信号强度，通常来说，信号强度高的Wi-Fi接入点可为设备提供质量较好的通信服务质量，故在按照信号强度选择法时，则在至少一个可选Wi-Fi接入点中，确定信号强度最高的Wi-Fi接入点为所述最优Wi-Fi接入点。
S102、设备根据所述最优Wi-Fi接入点的信息与当前连接的第一Wi-Fi接入点的信息，确定所述最优Wi-Fi接入点满足切换条件。
上述最优Wi-Fi接入点的信息具体可以为最优Wi-Fi接入点的标识、质量参数等，相应的第一Wi-Fi接入点的信息则为第一Wi-Fi接入点的标识、质量参数等，其中质量参数可以为信号强度、网络带宽等；在实际应用中，根据所述信息的具体内容的不同，上述切换条件相应的也会不同；例如在最优Wi-Fi接入点的信息为最优Wi-Fi接入点的标识时，第一Wi-Fi接入点的信息则为第一Wi-Fi接入点的标识，从而切换条件则为标识是否一致；当最优 Wi-Fi接入点的信息为最优Wi-Fi接入点的质量参数时，第一Wi-Fi接入点的信息则为第一Wi-Fi接入点的质量参数，从而切换条件则为：第一Wi-Fi接入点的质量参数表征的第一Wi-Fi接入点提供的通信服务质量，劣于最优Wi-Fi接入点的质量参数表征的最优Wi-Fi接入点提供的通信服务质量。
具体的，设备在搜索Wi-Fi接入点时，第一Wi-Fi接入点的信号也是被搜索到的，而在执行S101时，基于可能的预设方法，可选的，至少一个可选Wi-Fi接入点中不包括第一Wi-Fi接入点，则若以信号强度选择法执行S101时，确定的最优Wi-Fi接入点的信号强度可能小于第一Wi-Fi接入点，此时设备为了获得较好的通信服务质量，则不会选择与第一Wi-Fi接入点断开连接，因此设备在确定最优Wi-Fi接入点后，还需以信号强度作为上述Wi-Fi接入点的信息，判断确定所述最优Wi-Fi接入点与所述第一Wi-Fi接入点是否满足切换条件，即当最优Wi-Fi接入点的信号强度大于与所述第一Wi-Fi接入点的信号强度时，说明最优Wi-Fi接入点与所述第一Wi-Fi接入点满足切换条件；
或者可选的，至少一个可选Wi-Fi接入点中包括第一Wi-Fi接入点，则若以信号强度选择法执行S101时，确定的最优Wi-Fi接入点即为第一Wi-Fi接入点，此时设备也不会选择与第一Wi-Fi接入点断开连接，因此设备在确定最优Wi-Fi接入点后，还需以标识作为上述Wi-Fi接入点的信息，判断所述最优Wi-Fi接入点与所述第一Wi-Fi接入点是否满足切换条件，即当最优Wi-Fi接入点的标识与所述第一Wi-Fi接入点的标识不同时，即确定所述最优Wi-Fi接入点与所述第一Wi-Fi接入点满足切换条件。
S103、设备与当前连接的第一Wi-Fi接入点断开连接，并向所述最优Wi-Fi接入点发起连接请求。
由于设备位于多个Wi-Fi接入点的覆盖区域内，但同一时刻，设备仅与一个Wi-Fi接入点连接，为了与未连接的Wi-Fi接入点区分，本实施例中，将设备当前连接的Wi-Fi接入点称为第一Wi-Fi接入点；例如，设备在图2所示的位置A处与Wi-Fi接入点1建立连接，随后设备移动至位置B处，则此时Wi-Fi接入点1为第一Wi-Fi接入点；由于在S101中，设备确定最优Wi-Fi接入点为Wi-Fi接入点2，设备会与Wi-Fi接入点1断开连接，并向Wi-Fi接入点1发起连接请求。
本实施例中，当设备发现最优Wi-Fi接入点提供的通信服务质量优于当前连接的Wi-Fi接入点提供的通信服务质量时，设备会自动与当前连接的Wi-Fi接入点断开连接，并向最优Wi-Fi接入点发起连接，及时获取质量较优的通信服务质量，避免造成网络资源的浪费，且不需用户参与手动切换，提升了设备的人机交互智能化的特性。
图3为本发明通信连接的控制方法实施例二的流程示意图。如图3所示，本发明实施例是在图1所示的实施例的基础上做出进一步的描述，且本实施例也可使用图2所示的应用场景，具体如下：
S201、设备确定切换Wi-Fi接入点的触发事件发生。
上述切换Wi-Fi接入点的触发事件至少包括下述任意一种事件或至少两个事件的组合：
所述设备检测到第一Wi-Fi接入点的信号强度降低；所述设备感知到设备的移动状态发生了变化(例如通过加速度传感器、方向传感器等位移传感器感知)；或者是设备获知所述设备的位置改变，例如通过设备内的GPS(Global Positioning System，全球定位系统)模块,确定设备的位置改变；或者，还可以是所述设备检测到通过所述第一Wi-Fi接入点访问网络失败或访问速度降低。
S202、设备在搜索到的至少一个可选Wi-Fi接入点中确定最优Wi-Fi接入点。
灵活的，可以采用不同的质量参数来度量Wi-Fi接入点提供的通信服务质量的优劣，例如，可认为Wi-Fi接入点的信号强度高的Wi-Fi接入点提供的通信服务质量好；或者，可认为Wi-Fi接入点的网络带宽大的Wi-Fi接入点提供的通信服务质量好；或者，考虑到设备与Wi-Fi接入点距离越近，接收的Wi-Fi接入点的信号强度越高，则还可以根据Wi-Fi接入点与设备之间的距离，来预估Wi-Fi接入点提供的通信服务质量；还可能的，Wi-Fi接入点在部署时，运维人员根据各个Wi-Fi接入点提供的通信服务质量的优劣，按照通信服务质量由优至劣的顺序，为各个Wi-Fi接入点设置了不同的优先级，以告知设备各个Wi-Fi接入点提供的通信服务质量的优劣；也即在部署的各个Wi-Fi接入点中，优先级最高的Wi-Fi接入点提供的通信服务质量最好，优先级最低的Wi-Fi接入点提供的通信服务质量劣于部署的各个Wi-Fi接入 点中的其他Wi-Fi接入点；或者设备自身也会根据连接过的Wi-Fi接入点提供的通信服务质量，在本地为各个Wi-Fi接入点设置不同的优先级，也即在设备连接过的各个Wi-Fi接入点中，优先级最高的Wi-Fi接入点提供的通信服务质量最好，优先级最低的Wi-Fi接入点提供的通信服务质量劣于设备连接过的各个Wi-Fi接入点中的其他Wi-Fi接入点；由此可知，本实施例在确定最优Wi-Fi接入点时，可选的方式较多。
设备可以按照预设方法确定最优Wi-Fi接入点，例如，当所述预设方法为信号强度选择法，则所述设备根据各个所述可选Wi-Fi接入点的信号强度，确定信号强度最大的Wi-Fi接入点为所述最优Wi-Fi接入点；或者，
当所述预设方法为距离选择法，则所述设备根据各个所述可选Wi-Fi接入点的位置和所述设备的位置，选择与所述设备距离最近的Wi-Fi接入点为所述最优Wi-Fi接入点；或者，
当所述预设方法为网络带宽选择法，则所述设备根据各个所述可选Wi-Fi接入点的网络带宽，在所述搜索到的至少一个Wi-Fi接入点中选择网络带宽最大的Wi-Fi接入点为所述最优Wi-Fi接入点；或者，
当所述预设方法为网速选择法，则所述设备根据各个所述可选Wi-Fi接入点的网速，确定网速最大的可选Wi-Fi接入点为所述最优Wi-Fi接入点；
当所述预设方法为优先级选择法，则所述设备根据各个所述可选Wi-Fi接入点的优先级，确定优先级最高的可选Wi-Fi接入点为所述最优Wi-Fi接入点。
需要说明的是，通常设备开启Wi-Fi功能后，以预设周期搜索设备周围是否有Wi-Fi接入点的信号，由于Wi-Fi接入点的信号会携带该Wi-Fi接入点的标识等信息，当设备搜索到Wi-Fi接入点的信号，便会获得Wi-Fi接入点的标识，同时也可检测出该Wi-Fi接入点的信号强度；可能的，该Wi-Fi接入点在部署时，也将该Wi-Fi接入点连通的网络的网络带宽、网速等信息设置在该Wi-Fi接入点中，从而设备搜索到Wi-Fi接入点的信号时，也会接收到该Wi-Fi接入点发送的网络带宽、网速等；或者设备可与该Wi-Fi接入点试连接，以检测该Wi-Fi接入点连通的网络的网络带宽、网速，以便后续确定最优Wi-Fi接入点时使用；另外，Wi-Fi接入点的部署位置、也可设置在该Wi-Fi接入点中，从而设备搜索到Wi-Fi接入点的信号时，也会接收到该Wi-Fi 接入点发送的位置信息，或者，设备将Wi-Fi接入点的标识发送给远端服务器(如google地图服务器)，并接收远端服务器反馈的位置信息；故上述所述设备搜索到的任意一个Wi-Fi接入点的网络带宽是该Wi-Fi接入点发送给所述设备的，或者是所述设备通过对该Wi-Fi接入点进行检测获知的；所述设备搜索到的任意一个Wi-Fi接入点的网速是该Wi-Fi接入点发送给所述设备的，或者是所述设备通过对该Wi-Fi接入点进行检测获知的；所述设备搜索到的任意一个Wi-Fi接入点的访问速度是该Wi-Fi接入点发送给所述设备的，或者是所述设备通过对该Wi-Fi接入点进行检测获知的。
S203a、设备确定所述最优Wi-Fi接入点的标识与当前连接的第一Wi-Fi接入点的标识不同。
或者，不执行S203a，执行S203b：
S203b、设备根据所述最优Wi-Fi接入点的质量参数与所述第一Wi-Fi接入点的质量参数，确定所述最优Wi-Fi接入点提供的通信服务质量优于所述第一Wi-Fi接入点提供的通信服务质量。
其中，所述质量参数为下述任一项参数：
Wi-Fi接入点的信号强度、Wi-Fi接入点的网络带宽、Wi-Fi接入点的访问速度、Wi-Fi接入点的位置与所述设备的距离。
在图3所示的实施例中，是以S203a做以示例。
S204、设备与当前连接的第一Wi-Fi接入点的断开连接，并向所述最优Wi-Fi接入点发起连接请求。
本发明实施例中，每当设备确定切换Wi-Fi接入点的触发事件发生，便立即寻找最优Wi-Fi接入点，并在确定需选择的最优Wi-Fi接入点后，设备会自动与当前连接的Wi-Fi接入点断开连接，并向最优Wi-Fi接入点发起连接，及时获取质量较优的通信服务质量，避免造成网络资源的浪费，且不需用户参与手动切换，提升了设备的人机交互智能化的特性。
图4为本发明通信连接的控制方法实施例三的流程示意图。如图4所示，本实施例是在图1或图3所示的实施例的基础上，做出进一步说明，具体包括：
S301、设备确定切换Wi-Fi接入点的触发事件发生。
S302、设备在搜索到的至少一个可选Wi-Fi接入点中确定最优Wi-Fi接 入点。
具体确定方法可参见前述各个实施例；另外，由于设备可自动周期性的搜索设备周围是否有Wi-Fi接入点的信号，故上述至少一个可选Wi-Fi接入点可以是在S301之前便已搜索到，但也可能的，切换Wi-Fi接入点的触发事件触发设备进行搜索，即在S302之前，设备还需执行搜索可选Wi-Fi接入点的步骤。
S303a、当设备未连接Wi-Fi接入点时，则所述设备与最优Wi-Fi接入点建立连接。
还需补充说明的是,当设备未连接Wi-Fi接入点时，在S302之前，设备执行搜索可选Wi-Fi接入点的步骤时，可能未搜索到可选Wi-Fi接入点，则此时停止，即从S302开始的不再执行。
S303b、当设备连接第一Wi-Fi接入点时，设备判断所述最优Wi-Fi接入点的标识与第一Wi-Fi接入点的标识是否不同；若是，执行S304；若否，则停止。
还需补充说明的是，当设备连接第一Wi-Fi接入点时，则在S302之前，设备至少可搜索到第一Wi-Fi接入点的信号，即必然存在至少一个可选Wi-Fi接入点，也就是说，设备将当前连接的Wi-Fi接入点也作为可选Wi-Fi接入点，以进行最优Wi-Fi接入点的确定，从而可能的，确定的最优Wi-Fi接入点是当前连接的第一Wi-Fi接入点，故继续保持与第一Wi-Fi接入点的连接，即停止本实施；而最优Wi-Fi接入点不是第一Wi-Fi接入点时，即设备未连接的其他Wi-Fi接入点提供的通信服务质量优于第一Wi-Fi接入点，则需进行切换。
本实施例在图4中以S303b进行示例，可选的，S303b可采用下述S303c替换。
S303c、当设备连接第一Wi-Fi接入点时，设备根据所述最优Wi-Fi接入点的质量参数与所述第一Wi-Fi接入点的质量参数，判断所述最优Wi-Fi接入点提供的通信服务质量是否优于所述第一Wi-Fi接入点提供的通信服务质量；若是，执行S304；若否，则停止。
可能的，S301触发设备寻找最优Wi-Fi接入点，但设备是在除第一Wi-Fi接入点以外的其他Wi-Fi接入点中确定最优Wi-Fi接入点，也就是说，上述 可选Wi-Fi接入点不包括第一Wi-Fi接入点，则可能的，在S302之前搜索可选Wi-Fi接入点时，除了第一Wi-Fi接入点的信号以外，未搜索到其他Wi-Fi接入点的信号，从而确定的可选Wi-Fi接入点为0，则本实施例停止，即从S302开始不再执行。
然而，即使不考虑第一Wi-Fi接入点，设备也搜索到可选Wi-Fi接入点，则此时在不包括第一Wi-Fi接入点的可选Wi-Fi接入点中确定的最优Wi-Fi接入点提供的通信服务质量不一定优于第一Wi-Fi接入点，在最优Wi-Fi接入点提供的通信服务质量未优于第一Wi-Fi接入点提供的通信服务质量，则此时不需进行切换，即停止本实施例；而在第一Wi-Fi接入点提供的通信服务质量低于最优Wi-Fi接入点提供的通信服务质量，则进行切换。
S304、设备与当前连接的第一Wi-Fi接入点断开连接，并向所述最优Wi-Fi接入点发起连接请求。
向所述最优Wi-Fi接入点发起连接请求时，若该最优Wi-Fi接入点为公共Wi-Fi接入点，则设备可直接进行连接；若该最优Wi-Fi接入点不为公共Wi-Fi接入点，设置了密码，则设备需提供密码，该密码可以是设备已保存的密码，例如在本实施例之前，设备曾使用用户输入的密码，与该最优Wi-Fi接入点连接，则设备会保存该密码，则在再次连接时，设备自行提供保存的密码；但若在本实施例之前，设备未曾与该最优Wi-Fi接入点连接，则设备提示用户输入密码。
S305a、当设备与所述最优Wi-Fi接入点连接失败，则执行与第一Wi-Fi接入点建立连接的操作。
可能的，上述S305a可被下述S305b替换，图4是以S305a进行示例。
S305b、当设备通过所述最优Wi-Fi接入点访问网络失败，则执行与第一Wi-Fi接入点建立连接的操作。
为提升用户体验，最优Wi-Fi接入点未能连接，或连接后，通过最优Wi-Fi接入点不能访问网络，则恢复与第一Wi-Fi接入点的连接。
本发明实施例中，每当设备确定切换Wi-Fi接入点的触发事件发生，便立即寻找最优Wi-Fi接入点，并在确定需选择的最优Wi-Fi接入点后，设备会自动与当前连接的Wi-Fi接入点断开连接，并向最优Wi-Fi接入点发起连接，及时获取质量较优的通信服务质量，避免造成网络资源的浪费，且不需 用户参与手动切换，提升了设备的人机交互智能化的特性。
图5为本发明通信连接的控制方法实施例四的流程示意图。如图5所示，本实施例是在图1或图3所示的实施例的基础上，做出进一步说明，具体包括：
S401、设备确定切换Wi-Fi接入点的触发事件发生。
S402、设备根据所述设备存储的历史信息和搜索到的全部Wi-Fi接入点的标识，在搜索到的全部Wi-Fi接入点中确定可选Wi-Fi接入点。
其中，所述历史信息至少包括至少一个第二Wi-Fi接入点的标识；所述第二Wi-Fi接入点为设备连接成功的Wi-Fi接入点，本实施例中，每当设备与某个Wi-Fi接入点连接成功，设备会记录该Wi-Fi接入点的标识，具体是将该Wi-Fi接入点的标识记录在上述历史信息中，则在S402中，设备根据所述设备存储的历史信息，在搜索到的全部Wi-Fi接入点中，确定标识存在于所述历史信息中的至少一个Wi-Fi接入点为至少一个所述可选Wi-Fi接入点；与前述图4所示的实施例对比可知，本实施例是在搜索到的全部Wi-Fi接入点中，依据历史信息确定可选Wi-Fi接入点；而图4所示的实施例中，是将搜索到的全部Wi-Fi接入点均作为可选Wi-Fi接入点(可能筛除第一Wi-Fi接入点或不筛除第一Wi-Fi接入点)。
另外，上述历史信息还包括连接成功的Wi-Fi接入点的密码(若该Wi-Fi接入点为公共Wi-Fi接入点，则不用记录密码)、协议信息、信号强度、网络带宽、网速、位置及用户为该Wi-Fi接入点设置的优先级等。
需要说明的是，设备在当前时刻连接于第一Wi-Fi接入点，该“第一”是用于特指设备在当前时刻连接的Wi-Fi接入点；而在设备与该第一Wi-Fi接入点连接成功后，设备至少会将该第一Wi-Fi接入点的标识记录在历史信息中，则以历史信息的视角来说，该第一Wi-Fi接入点则为标识被设备记录在历史信息中的第二Wi-Fi接入点。
另外，本实施例中，可选Wi-Fi接入点的标识存在于所述设备的历史信息中，说明可选Wi-Fi接入点在当前时刻之前，曾与设备连接成功过，也可以说确定的至少一个可选Wi-Fi接入点均是设备认证过的，其安全性得以保证，避免设备切换到存在安全隐患的Wi-Fi接入点。
由于设备可自动周期性的搜索设备周围是否有Wi-Fi接入点的信号，故 上述搜索到的全部Wi-Fi接入点可以是在S401之前便已搜索到，但也可能的，切换Wi-Fi接入点的触发事件触发设备进行搜索，即在S402之前，设备还需执行搜索Wi-Fi接入点的步骤。
S403、设备在搜索到的至少一个可选Wi-Fi接入点中确定最优Wi-Fi接入点。
可选的，可参照前述各个实施例；但灵活的，本实施例结合前述历史信息，提供一种预设方法为优先级选择法，具体的，设备与任一个Wi-Fi接入点连接成功后，可对连接成功的Wi-Fi接入点设置优先级，则历史信息还包括各个所述第二Wi-Fi接入点的标识对应的优先级，所述设备根据各个所述可选Wi-Fi接入点的标识查询所述历史信息，获取各个所述可选Wi-Fi接入点的标识对应的优先级；所述设备在至少一个所述可选Wi-Fi接入点中选择所述标识对应的优先级为最高的可选Wi-Fi接入点为所述最优Wi-Fi接入点；或者
所述历史信息还包括各个所述第二Wi-Fi接入点的标识对应的时间，所述时间为所述设备与第二Wi-Fi接入点连接成功的时间，则当所述预设方法为时间选择法时，所述设备根据各个所述可选Wi-Fi接入点的标识查询所述历史信息，获取各个所述可选Wi-Fi接入点的标识对应的时间；所述设备在至少一个所述可选Wi-Fi接入点中选择所述标识对应的时间点最靠近所述当前时刻的可选Wi-Fi接入点为所述最优Wi-Fi接入点。
S404a、当设备未连接Wi-Fi接入点时，则所述设备与最优Wi-Fi接入点建立连接。
还需补充说明的是,当设备未连接Wi-Fi接入点时，在S402之前，设备执行搜索Wi-Fi接入点的步骤时，可能未搜索到任意一个Wi-Fi接入点，则此时停止，即从S402开始不再执行；或者搜索到的全部Wi-Fi接入点均是设备之前未接入的Wi-Fi接入点，则处于安全考虑，在S402中确定的可选Wi-Fi接入点的数目为0，则此时停止，从S402之后不再执行。
S404b、当设备连接第一Wi-Fi接入点时，设备判断所述最优Wi-Fi接入点的标识与第一Wi-Fi接入点的标识是否不同；若是，执行S405；若否，则停止。
还需补充说明的是，可能的，S402之前，设备至少可搜索到第一Wi-Fi 接入点的信号，即必然存在至少一个Wi-Fi接入点，且在确定可选Wi-Fi接入点时，未筛除该第一Wi-Fi接入点；也就是说，设备将当前连接的Wi-Fi接入点也作为可选Wi-Fi接入点，以进行最优Wi-Fi接入点的确定，从而可能的，确定的最优Wi-Fi接入点是当前连接的第一Wi-Fi接入点，故继续保持与第一Wi-Fi接入点的连接，即停止本实施；而最优Wi-Fi接入点不是第一Wi-Fi接入点，即设备未连接的其他Wi-Fi接入点提供的通信服务质量优于第一Wi-Fi接入点，则需进行切换。
本实施例中，图5是以S404b作为示例，可选的，S404b可采用下述S404c替换。
S404c、当设备连接第一Wi-Fi接入点时，设备根据所述最优Wi-Fi接入点的质量参数与所述第一Wi-Fi接入点的质量参数，判断所述最优Wi-Fi接入点提供的通信服务质量是否优于所述第一Wi-Fi接入点提供的通信服务质量；若是，执行S405；若否，则停止。
可能的，S402之前，设备至少可搜索到第一Wi-Fi接入点的信号，即必然存在至少一个Wi-Fi接入点，但在确定可选Wi-Fi接入点时，筛除了该第一Wi-Fi接入点；也就是说，上述可选Wi-Fi接入点不包括第一Wi-Fi接入点，则可能的，S302中确定的可选Wi-Fi接入点的数目为0，此时则停止；即从S402开始不再执行。
然而，即使不考虑第一Wi-Fi接入点，设备也确定了可选Wi-Fi接入点，则此时在不包括第一Wi-Fi接入点的可选Wi-Fi接入点中确定的最优Wi-Fi接入点提供的通信服务质量不一定优于第一Wi-Fi接入点，在最优Wi-Fi接入点提供的通信服务质量未优于第一Wi-Fi接入点提供的通信服务质量，则此时不需进行切换，即停止本实施例；而在第一Wi-Fi接入点提供的通信服务质量低于最优Wi-Fi接入点提供的通信服务质量，则进行切换。
S405、设备与当前连接的第一Wi-Fi接入点的断开连接，并向所述最优Wi-Fi接入点发起连接请求。
向所述最优Wi-Fi接入点发起连接请求时，若该最优Wi-Fi接入点为公共Wi-Fi接入点，则设备可直接进行连接；若该最优Wi-Fi接入点不为公共Wi-Fi接入点，设置了密码，但本实施例中可选Wi-Fi接入点均为设备曾连接成功过的Wi-Fi接入点，则设备根据已保存的密码，与最优Wi-Fi接入点连 接。
S406a、当设备与所述最优Wi-Fi接入点连接失败，则执行与第一Wi-Fi接入点建立连接的操作。
可能的，上述S406a可被下述S406b替换，图5是以S406a进行示例。
S406b、当设备通过所述最优Wi-Fi接入点访问网络失败，则执行与第一Wi-Fi接入点建立连接的操作。
本发明实施例中，每当设备确定切换Wi-Fi接入点的触发事件发生，便立即寻找最优Wi-Fi接入点，并在确定需选择的最优Wi-Fi接入点后，设备会自动与当前连接的Wi-Fi接入点断开连接，并向最优Wi-Fi接入点发起连接，及时获取质量较优的通信服务质量，避免造成网络资源的浪费，且不需用户参与手动切换，提升了设备的人机交互智能化的特性。
图6为本发明设备实施例一的结构示意图。如图6所示，本实施例中的设备具有无线保真Wi-Fi功能，包括：
第一确定模块11，用于在搜索到的至少一个可选无线保真Wi-Fi接入点中确定最优Wi-Fi接入点；
第二确定模块12，用于根据所述最优Wi-Fi接入点的信息与当前连接的第一Wi-Fi接入点的信息，确定所述最优Wi-Fi接入点满足切换条件；
切换模块13，用于与所述第一Wi-Fi接入点的断开连接，并向所述最优Wi-Fi接入点发起连接请求。
本发明实施例中，当设备发现最优Wi-Fi接入点提供的通信服务质量优于当前连接的Wi-Fi接入点提供的通信服务质量时，设备会自动与当前连接的Wi-Fi接入点断开连接，并向最优Wi-Fi接入点发起连接，及时获取质量较优的通信服务质量，避免造成网络资源的浪费，且不需用户参与手动切换，提升了设备的人机交互智能化的特性。
图7为本发明设备实施例二的结构示意图。如图7所示，本实施例是在图6所示的实施例的基础上，做出进一步描述，具体的，设备还包括：第三确定模块14，用于确定切换Wi-Fi接入点的触发事件发生；
其中，所述切换Wi-Fi接入点的触发事件至少包括下述任意一种事件或至少两个事件的组合：
所述设备检测到第一Wi-Fi接入点的信号强度降低、所述设备获知所述 设备的位置改变、所述设备检测到通过所述第一Wi-Fi接入点访问网络失败或访问速度降低。
可选的，当所述信息为标识，所述第二确定模块具体用于确定所述最优Wi-Fi接入点的标识与当前连接的第一Wi-Fi接入点的标识不同；或者，
当所述信息为质量参数，所述第二确定模块具体用于根据所述最优Wi-Fi接入点的质量参数与所述第一Wi-Fi接入点的质量参数，确定所述最优Wi-Fi接入点提供的通信服务质量优于所述第一Wi-Fi接入点的通信服务质量；
其中，所述质量参数为下述至少一项参数：
Wi-Fi接入点的优先级、Wi-Fi接入点的信号强度、Wi-Fi接入点的网络带宽、Wi-Fi接入点的访问速度、Wi-Fi接入点的位置与所述设备的距离。
