具体实施方式
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的一部分实施例，而不是全部实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动的前提下所获得的所有其他实施例，都应属于本发明保护的范围。
为了方便理解本发明实施例，首先在此介绍本发明实施例描述中会引入的几个要素。
蓝牙主设备，可以搜索周围的蓝牙从设备，用户可以选择需要连接的蓝牙从设备，可主动发起蓝牙配对，通过匹配密码来将蓝牙主设备和蓝牙从设备匹配，具有蓝牙功能的智能手机、个人计算机(Personal Computer，简称为“PC”)等都属于蓝牙主设备。
蓝牙从设备，不主动发起蓝牙配对请求的设备，蓝牙从设备一般不具备输入端，通常在蓝牙从设备出厂时在蓝牙从设备的蓝牙芯片中固化有一个4位或6位数字的匹配密码，蓝牙音箱、蓝牙耳机等都是蓝牙从设备。
在本发明实施例中，蓝牙主设备断开与蓝牙从设备的蓝牙连接指的是蓝牙主设备断开与蓝牙从设备的物理层连接，蓝牙连接断开不会导致蓝牙主设备的蓝牙功能被关闭，因此蓝牙主设备还可以与其他蓝牙从设备建立蓝牙连接。
蓝牙主设备的蓝牙功能关闭，即蓝牙模块不工作，则蓝牙主设备不能和其他蓝牙从设备建立蓝牙连接。
蓝牙功能的开启和关闭，可以通过蓝牙主设备上蓝牙开关图标的进行操作。如图1a所示为蓝牙主设备上的蓝牙开关图标，如图1a左图所示为关闭蓝牙功能，如图1a右图所示为开启蓝牙功能。如图1b所示为蓝牙开关图标的另一种形式，当用户点击蓝牙开关图标，蓝牙开关图标变成灰色，关闭蓝牙功能；当用户点击蓝牙开关，蓝牙开关图标变高亮，则开启蓝牙功能。蓝牙功能关闭会导致蓝牙主设备断开与蓝牙从设备的蓝牙连接。一般在蓝牙主 设备上如果有已配对的蓝牙从设备，可以通过菜单操作选择连接该蓝牙从设备，或者断开与该蓝牙从设备的连接，还可以通过菜单操作选择取消与该已配对的蓝牙从设备的配对。蓝牙主设备和蓝牙从设备断开蓝牙连接，依然会保留配对信息，下次再与蓝牙从设备连接时，不需要再进行配对。若蓝牙主设备和蓝牙从设备取消配对了，则下次建立蓝牙连接时，需要先进行配对。
本发明实施例应用于蓝牙主设备与蓝牙从设备通过建立蓝牙连接进行数据交互的场景中。如图2中示出的，智能手机A-D为蓝牙主设备，蓝牙音箱为蓝牙从设备，根据现有相关技术的方法，在需要将智能手机A-D与蓝牙音箱进行配对或连接时，需要用户手动开启智能手机A-D的蓝牙功能。并且，当智能手机A与蓝牙音箱建立了蓝牙连接后，需要用户手动关闭智能手机A的蓝牙开关或手动断开蓝牙连接，智能手机B-D之一才能和蓝牙音箱建立连接。否则，即使智能手机A与蓝牙音箱没有数据传输，智能手机A仍会保持与蓝牙音箱的蓝牙连接，占用信道，智能手机B-D无法与蓝牙音箱建立蓝牙连接，造成资源的浪费。
基于此，可以提供一种管理蓝牙连接的方法，避免资源浪费。
下面将以蓝牙主设备为智能手机为例，描述本发明实施例的管理蓝牙连接的方法。可以理解的是，以智能手机为例仅是为了描述方便，而不对本发明实施例的保护范围构成限定。

下面将结合具有图3示出的智能手机100的结构的智能手机A和智能手机B与蓝牙音箱之间建立蓝牙连接为例，描述根据本发明实施例的管理蓝牙连接的方法。如图4所示，方法1000包括：
S1100，智能手机A的处理器170确定智能手机A是否与蓝牙音箱通过蓝牙连接有数据传输；
具体地，智能手机A通过蓝牙模块160与蓝牙音箱建立蓝牙连接后，智 能手机A的处理器170确定智能手机A是否与蓝牙音箱通过蓝牙连接进行数据传输，示例性的，数据传输指的是音乐、文档、视频等信息的传输。
可选地，作为一个例子，智能手机A的处理器170通过智能手机A的蓝牙模块160的工作功率来确定智能手机A是否通过蓝牙连接与蓝牙音箱进行数据传输，智能手机A的蓝牙模块160的工作功率可以为发射功率和/或接收功率。
举例来说，在智能手机A的处理器170确定智能手机A是否通过蓝牙连接与蓝牙音箱进行数据传输时，可以预先设置检测智能手机A的蓝牙模块160的工作功率的时间点，智能手机A的处理器170在每个预设的时间点检测智能手机A的蓝牙模块160的工作功率，当智能手机A的处理器170在某个时间点检测到智能手机A的蓝牙模块160的工作功率低于预设功率阈值时，智能手机A的处理器170确定智能手机A与蓝牙音箱没有进行数据传输。具体地，智能手机A的处理器可以周期性地检测智能手机A的蓝牙模块160的工作功率。
或者智能手机A的处理器170实时检测智能手机A的蓝牙模块160的工作功率，当检测到智能手机A的蓝牙模块160的工作功率低于预设功率阈值时开始计时，当智能手机A的处理器170检测到智能手机A的蓝牙模块160的工作功率小于预设功率阈值的持续时间超过预设时长，则认为智能手机A没有通过蓝牙连接与蓝牙音箱进行数据传输。当智能手机A的处理器170检测到蓝牙模块160的工作功率不小于预设功率阈值时，或者当蓝牙模块160的工作功率小于预设功率阈值的持续时长未超过预设时长时，则认为智能手机A与蓝牙音箱进行数据传输。
或者，智能手机A的处理器170可以统计智能手机A的蓝牙模块160在预设时长内的工作功率的总和，根据工作功率的总和与预设功率阈值的大小关系，确定智能手机A是否与蓝牙音箱通过蓝牙连接进行数据传输。与工作功率的总和比较的预设功率阈值和前一段中提到的预设功率阈值可设置为不同值。
可选地，智能手机A的处理器170根据智能手机A的蓝牙模块160在一段时间内蓝牙模块160的工作功率与预设功率阈值的大小关系，确定智能手机A是否与蓝牙音箱通过蓝牙连接进行数据传输。P为智能手机A的蓝牙模块160的工作功率，P可用公式(1)表示：
Figure PCTCN2016087816-appb-000001
公式(1)中，x是智能手机A的蓝牙模块160发送或接收的蓝牙信号(对于蓝牙音箱主要是发送信号)，X可以表示为以时间和角频率为变量的函数，
Figure PCTCN2016087816-appb-000002
其中，A(t)表示蓝牙信号的振幅；ω＝2πf表示角频率，f表示传输蓝牙信号的频率；
Figure PCTCN2016087816-appb-000003
表示蓝牙信号的初始相位；X2表示功率；t表示时间；N表示时间长度，其中N的取值可以根据实际需要进行设置。
可选地，可以从智能手机A中的电源管理模块中获取蓝牙模块160的工作功率。
具体地，智能手机A的处理器170可以以任何一个时间点为起点开始记录智能手机A的蓝牙模块160的工作功率，当智能手机A的处理器170统计到一段时间内智能手机A的蓝牙模块160的工作功率的总和后，将工作功率的总和与预设功率阈值Pthreshold进行比较，如果P小于Pthreshold，则认为智能手机A没有与蓝牙音箱通过蓝牙连接进行数据传输，需要断开与蓝牙音箱的蓝牙连接。如果P大于或等于Pthreshold，则认为智能手机A与蓝牙音箱通过蓝牙连接有数据的传输，不需要断开智能手机A与蓝牙音箱的蓝牙连接。
可选地，作为一个例子，智能手机A的处理器170可以根据蓝牙音箱对应的应用程序(Application，简称为“APP”)的状态，确定智能手机A是否与蓝牙音箱通过蓝牙连接进行数据传输。当智能手机A的处理器170确定蓝牙音箱对应的APP处于开启状态时，确定智能手机A与蓝牙音箱通过蓝牙连接进行数据传输，当智能手机A的处理器170确定蓝牙音箱对应的APP处于关闭状态时，确定智能手机A与蓝牙音箱没有通过蓝牙连接进行数据传输。
S1200，当智能手机A确定没有与蓝牙音箱通过蓝牙连接进行数据传输时，智能手机A断开与蓝牙音箱的蓝牙连接。
本实施例中智能手机A能够检测蓝牙连接的使用情况，即是否通过蓝牙连接进行数据传输，以此控制与蓝牙音箱的蓝牙连接，当确定没有通过蓝牙连接进行数据传输，则断开与蓝牙音箱的连接，这样其他智能手机可以与蓝牙音箱建立蓝牙连接。
进一步地，当智能手机A断开与蓝牙音箱的蓝牙连接后，可以关闭智能手机A的蓝牙功能，并提示用户蓝牙功能被关闭，这样可以节省手机耗电量。
可选地，作为一个例子，当智能手机A确定与蓝牙音箱没有数据传输后，智能手机A断开和蓝牙音箱的蓝牙连接前，智能手机A通过蓝牙连接通知蓝牙音箱进入配对状态或待连接状态。现有技术中在蓝牙主设备被用户手动断开蓝牙连接后，对应的蓝牙从设备仍无法和其他蓝牙主设备建立连接，需要用户手动重启蓝牙从设备，蓝牙从设备才能和其他蓝牙主设备建立连接，在这个例子中，智能手机A在断开和蓝牙音箱的蓝牙连接之前指示蓝牙音箱进入配对状态或待连接状态，蓝牙音箱收到指示后切换状态，这样其他智能手机可以与蓝牙音箱连接。
可选地，作为一个例子，智能手机A的处理器170检测智能手机A的蓝牙开关图标的状态，当蓝牙开关图标关闭，通知蓝牙音箱进入待连接状态或配对状态，断开智能手机A和蓝牙音箱的蓝牙连接。
当蓝牙从设备处于待连接状态时，蓝牙从设备可以被与之前配对过的蓝牙主设备搜索到进行蓝牙连接。
当蓝牙从设备处于配对状态时，蓝牙从设备能够被与未配对过的蓝牙主设备搜索到，通过密钥配对方式进行配对，建立蓝牙连接。
例如在图4中所示出的，假设智能手机A和智能手机B均与蓝牙音箱配对过，智能手机A通知蓝牙音箱进入待连接状态，智能手机A和蓝牙音箱的蓝牙连接断开，蓝牙音箱进入待连接状态，当智能手机B的蓝牙功能被开启后，智能手机B的蓝牙模块160进行设备搜索，当搜索到蓝牙音箱时，智能手机B自动与蓝牙音箱建立连接。智能手机A通知蓝牙音箱进入待连接状态，可以通过指示蓝牙音箱进行关机再开机来实现。
假设图4中的智能手机B未与蓝牙音箱配对过，智能手机A通知蓝牙音箱进入配对状态，智能手机A和蓝牙音箱的蓝牙连接断开，蓝牙音箱进入配对状态，当智能手机B的蓝牙功能被开启后，智能手机B的蓝牙模块160进行设备搜索，当搜索到蓝牙音箱时，需要智能手机B通过配对密码，完成智能手机B与蓝牙音箱之间的配对连接。智能终端B与蓝牙音箱配对连接后，蓝牙音箱会保存智能终端B的信息，当下次智能终端B再搜索到该蓝牙音箱时，智能终端B可以直接与该蓝牙音箱建立蓝牙连接。
可选地，作为一个例子，假设图4中，智能手机A断开与蓝牙音箱的蓝牙连接后，智能手机B-D均希望与蓝牙音箱建立连接，如果智能手机B-D中，只有智能手机B与蓝牙音箱配对过，则蓝牙音箱与智能手机B建立蓝 牙连接；如果智能手机B-D均与蓝牙音箱配对过，则可以按照预设设置的优先级顺序，优先级最高的智能手机D与蓝牙音箱进行配对建立蓝牙连接。
在现有技术中，当用户需要使用蓝牙音箱时，需要手动打开智能手机A的蓝牙开关，搜索周围的蓝牙设备，手动选择蓝牙音箱触发智能手机A和蓝牙音箱的蓝牙连接，当用户不需要使用蓝牙音箱时，需要用户手动断开蓝牙连接或关闭蓝牙功能，以上均需要用户通过手动方式实现，会影响用户的用户体验。基于此，可以提供一种自动开启和关闭智能手机A的蓝牙功能的方法，简化用户操作，提高用户的用户体验。
下面将结合具体的实施例，描述根据本发明实施例的自动开启和关闭智能手机A的蓝牙功能的方法，以智能手机A上安装有蓝牙音箱对应的APP为例，在智能手机A上安装与蓝牙音箱对应的APP的过程中，智能手机A的存储器120会记录与蓝牙音箱对应的APP相关的属性，这些相关的属性可以包括APP是否需要应用蓝牙功能、APP是否具有打开智能手机A的蓝牙功能的权限等，还可包括蓝牙音箱对应的APP对应的蓝牙设备类型，如蓝牙耳机，蓝牙音箱，蓝牙手环等，并且APP安装完成后会在智能手机A的显示单元140上显示与APP相对应的图标，方便用户的操作，例如图5中所示的智能手机A的用户界面，APP对应的图标为“蓝牙音箱”，以下蓝牙音箱对应的APP称作“蓝牙音箱APP”。
本发明的实施例中可以在智能手机A的存储器120中存储蓝牙音箱APP的开关状态和所需的蓝牙功能的状态的对应关系，表1中示出了一种可能的蓝牙音箱APP的开关状态和所需的蓝牙功能的状态的对应关系。
表1
蓝牙音箱APP 蓝牙功能
开 开
关 关
智能手机A的处理器170检测蓝牙APP的开启状态，来决定蓝牙功能的开关状态。当检测到蓝牙音箱APP由关闭切换到开启，智能手机A确定当前蓝牙功能的状态，判断是否与所需的蓝牙功能的状态一致，如当前蓝牙功能状态为关闭，蓝牙音箱APP开启所需的蓝牙功能状态为开启，两者不一致，则将当前蓝牙功能的状态切换为该所需的蓝牙功能的状态，即将当前蓝牙功能的状态切换为开启，两者一致则保持；相应地，当检测到蓝牙音箱 APP由开启切换到关闭，智能手机A确定当前蓝牙功能的状态是否是已经关闭，若是则保持关闭状态，若不是，则智能手机A关闭蓝牙功能。该智能手机A的存储器120内可存储有蓝牙音箱APP对应的蓝牙音箱的信息，当蓝牙音箱APP变为开启状态，蓝牙功能处于开启状态时，智能手机A对周围的蓝牙设备进行搜索；当智能手机A搜索到该蓝牙音箱时，自动与该蓝牙音箱建立蓝牙连接。
图6是根据本发明另一实施例的管理蓝牙连接的方法。如图6所示方法2000包括：
S2100，当蓝牙音箱APP被启动，蓝牙音箱APP确定智能手机A的蓝牙功能是否被开启；
用户通过点击智能手机A的显示单元140上的“蓝牙音箱”图标(如图5所示出的)，打开蓝牙音箱APP。智能手机A运行蓝牙音箱APP。
具体地，蓝牙音箱APP通过检测智能手机A中的蓝牙模块160的状态，确定智能手机A的蓝牙功能是否被开启。或者蓝牙音箱APP读取蓝牙开关图标的状态，确定智能手机A的蓝牙功能是否被开启。
如果智能手机A的蓝牙功能已经开启，直接执行S2200。否则当蓝牙音箱APP确定智能手机A的蓝牙功能没有打开时，执行步骤2110蓝牙音箱APP通过向智能手机A的蓝牙模块160发送开启智能手机A的蓝牙功能的指令开启智能手机A的蓝牙功能，之后执行S2200。
S2200，蓝牙音箱APP与蓝牙音箱建立蓝牙连接；
如果蓝牙音箱APP与蓝牙音箱配对过，智能手机A中的存储器中120记录有蓝牙音箱APP和蓝牙音箱的配对信息，在智能手机A的蓝牙功能被开启后，蓝牙音箱APP搜索蓝牙音箱，在搜索到蓝牙音箱时自动与蓝牙音箱建立蓝牙连接。
如果蓝牙音箱APP之前未与蓝牙音箱配对过，在智能手机A的蓝牙功能被开启后，扫描周围的蓝牙设备，根据蓝牙音箱APP对应的蓝牙设备类型自动与蓝牙音箱进行配对，配对之后，智能手机A的存储器120会保存蓝牙音箱的身份识别信息、蓝牙音箱的功能信息等，在蓝牙音箱APP再被开启之后，蓝牙音箱APP自动搜索该身份标识信息对应的蓝牙音箱，并与蓝牙音箱自动建立蓝牙连接。
可选地，如果蓝牙音箱APP之前未与蓝牙音箱配对过，在智能手机A 的蓝牙功能被开启后，智能手机A可以进入蓝牙设置界面，显示周围的蓝牙设备，用户可以手动选择蓝牙音箱进行配对。
S2300，蓝牙音箱APP判断是否接收到退出运行的指示；
用户可以通过操作蓝牙音箱APP退出蓝牙音箱APP，或者通过手机应用管理软件将蓝牙音箱APP退出运行。
S2400，蓝牙音箱APP在收到退出运行指示时，通知蓝牙音箱进入待连接状态或配对状态。
其中，S2400为可选步骤，步骤S2300之后可以直接执行S2500。
可以理解的是，在蓝牙音箱进入待连接状态或配对状态后，假设智能手机B上的蓝牙音箱APP希望与蓝牙音箱建立蓝牙连接，如果智能手机B上的蓝牙音箱APP之前与蓝牙音箱配对过，智能手机B上的蓝牙音箱APP可以自动与蓝牙音箱建立连接。否则，智能手机B上的蓝牙音箱APP与蓝牙音箱通过密钥配对进行蓝牙连接。
S2500，蓝牙音箱APP断开和蓝牙音箱的蓝牙连接；
需要说明的是，蓝牙音箱APP断开和蓝牙音箱的蓝牙连接指的是断开智能手机A的蓝牙模块与蓝牙音箱的物理层连接，也即蓝牙音箱APP断开和蓝牙音箱之间的数据传输通道。
S2600，蓝牙音箱APP关闭智能手机A的蓝牙功能；
具体地，蓝牙音箱APP通过指示智能手机A的蓝牙模块160关闭智能手机A的蓝牙功能，以减少智能手机A的耗电量。
可选地，S2600之前，蓝牙音箱APP可以判断蓝牙音箱APP打开时，智能手机A的蓝牙功能是否开启，若开启，则不执行S2600；若智能手机A的蓝牙功能未开启，则执行S2600。以实现蓝牙音箱APP关闭后，智能手机A的蓝牙功能恢复蓝牙音箱APP开启前的状态。
本实施例中蓝牙音箱APP可以由蓝牙音箱的厂商提供，蓝牙音箱APP带有上述步骤对应的程序代码，本实施例中的步骤可以由智能手机A的处理器170运行蓝牙音箱APP来实现。
下面将结合再一具体的实施例，描述根据本发明实施例的自动开启和关闭智能手机A的蓝牙功能的方法，以智能手机A上安装有蓝牙音箱对应的APP为例，APP安装完成后会在智能手机A的显示单元140上显示与APP相对应的图标，方便用户的操作，例如图5中所示的智能手机A的用户界面， APP对应的图标为“蓝牙音箱”，以下蓝牙音箱对应的APP称作“蓝牙音箱APP”。图7示出了根据本发明再一实施例的管理蓝牙连接的方法，如图7所示，方法3000包括：

用户通过点击智能手机A的显示单元140上的“蓝牙音箱”图标(如图5所示出的)，打开蓝牙音箱APP。
S3200，智能手机A根据蓝牙音箱APP的属性确定蓝牙音箱APP是否具有使用蓝牙功能的权限；当确定蓝牙音箱APP有蓝牙功能的使用权限时，执行步骤S3300；可选地智能手机A可以跳过S3200，在执行S3100后执行S3300。
具体地，蓝牙音箱APP的属性可以在安装时记录到智能手机A的存储器120中的默认设置，也可以是蓝牙音箱APP之前运行时用户设置的。可以包括蓝牙音箱APP是否具有使用蓝牙功能的权限，蓝牙音箱APP绑定的蓝牙音箱的身份标识信息等。
S3300，智能手机A判断蓝牙功能是否开启，若开启则执行S3500；若未开启则执行S3400；
S3400，智能手机A开启蓝牙功能；
S3500，智能手机A与蓝牙音箱建立蓝牙连接；
如果蓝牙音箱APP与蓝牙音箱配对过，智能手机A中的存储器中120记录有蓝牙音箱APP和蓝牙音箱的配对信息，在智能手机A的蓝牙功能被开启后，搜索配过对的蓝牙音箱，在搜索到蓝牙音箱时自动与蓝牙音箱建立蓝牙连接。
如果蓝牙音箱APP之前未与蓝牙音箱配对过，在智能手机A的蓝牙功能被开启后，需要蓝牙音箱APP先与蓝牙音箱进行配对，用户通过智能手机A的输入单元130输入配对密码，实现蓝牙音箱APP与蓝牙音箱的配对，配对之后，智能手机A的存储器120会保存蓝牙音箱的身份识别信息、蓝牙音箱的功能信息等，在蓝牙音箱APP再被开启之后，自动搜索蓝牙音箱，并与蓝牙音箱自动建立蓝牙连接。
S3600，智能手机A检测到蓝牙音箱APP被退出运行；
用户可以通过操作蓝牙音箱APP退出蓝牙音箱APP，或者通过手机应用管理软件将蓝牙音箱APP退出运行。
S3700，智能手机A通过蓝牙连接通知蓝牙音箱进入待连接状态或配对状态。
可以理解的是，在蓝牙音箱进入待连接状态或配对状态后，假设智能手机B上的蓝牙音箱APP希望与蓝牙音箱建立蓝牙连接，如果智能手机B上的蓝牙音箱APP之前与蓝牙音箱配对过，智能手机B上的蓝牙音箱APP可以自动与蓝牙音箱建立连接。否则，智能手机B上的蓝牙音箱APP与蓝牙音箱通过密钥配对进行蓝牙连接。
S3700为可选步骤，步骤S3600之后可以直接执行S3800。
S3800，智能手机A和蓝牙音箱断开蓝牙连接；
需要说明的是，智能手机A断开和蓝牙音箱的蓝牙连接指的是断开智能手机A的蓝牙模块与蓝牙音箱的物理层连接，也即蓝牙音箱APP断开和蓝牙音箱之间的数据传输通道。
S3900，智能手机A关闭智能手机A的蓝牙功能；
具体地，智能手机A关闭智能手机A的蓝牙功能，以减少智能手机A的耗电量。
可选地，S3900之前，智能手机A可以判断蓝牙音箱APP打开时智能手机A的蓝牙功能是否开启，若开启，则不执行S3900；若智能手机A的蓝牙功能未开启，则执行S3900。以实现蓝牙音箱APP关闭后，智能手机A的蓝牙功能恢复蓝牙音箱APP开启前的状态。
本实施例中智能手机A执行上述步骤的程序代码可与蓝牙音箱APP的代码相独立，即可以是其他应用，如手机的管理应用。
以上图6和图7的实施例中可以结合图4的实施例，即在蓝牙音箱APP运行时，检测是否与蓝牙音箱有数据传输，若没有数据传输时，则自动断开与蓝牙音箱的蓝牙连接。

处理单元25，用于当所述第二状态为开启状态且蓝牙功能的状态为开启状态时，使所述蓝牙主设备自动与该蓝牙从设备建立蓝牙连接。
可以理解地，此处蓝牙功能的状态为开启状态，是指蓝牙功能实际为开启状态，而不是所需的蓝牙功能状态。可以理解地，对于未配对的蓝牙从设 备，蓝牙主设备自动和蓝牙从设备建立蓝牙连接之前还包括进行配对操作。
应理解，根据本发明实施例的装置20可对应于本发明实施例的方法2000中蓝牙音箱APP，并且，装置20中的各单元即模块和上述其他操作和/或功能分别为了实现方法2000的相应流程，为了简洁，在此不再赘述。
