Description

一种建立通信连接的方法及可穿戴设备
本申请要求于2019年7月18日提交国家知识产权局、申请号为201910650281.8、发明名称为“一种建立通信连接的方法及可穿戴设备”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及终端技术领域，尤其涉及一种建立通信连接的方法及可穿戴设备。
背景技术
目前，一个用户往往具备多个智能终端。例如，用户可以拥有手机、平板电脑、智能手表以及蓝牙耳机等多个终端。其中，蓝牙耳机可作为输出设备分别与用户其他的终端建立通信连接，进而，用户可使用蓝牙耳机播放与其相连的终端(即音源设备)中的音频内容。
一般，蓝牙耳机可以保存最近一次连接的终端的地址(例如，终端的蓝牙地址)。用户打开蓝牙耳机后，蓝牙耳机可根据已保存的终端的地址尝试搜索该终端的蓝牙信号。如果搜索到该终端的蓝牙信号，则蓝牙耳机可自动与最近一次连接的终端建立蓝牙连接。
但是，如果没有搜索到最近一次连接的终端的蓝牙信号，则用户需要在等待连接的终端中打开蓝牙设备列表，并在蓝牙设备列表中选择蓝牙耳机作为本次的连接设备，从而触发该终端与蓝牙耳机建立蓝牙连接。可以看出，用户需要在终端上执行多次操作，才能建立蓝牙耳机与用户所需的终端之间的蓝牙连接，整个连接过程耗时较长，操作较为繁琐，用户的使用体验不高。
发明内容
本申请提供一种建立通信连接的方法及可穿戴设备，可简单、快捷的完成设备之间通信连接的建立过程，简化操作流程，提高用户的使用体验。
为达到上述目的，本申请采用如下技术方案：
第一方面，本申请提供一种建立通信连接的方法，包括：可穿戴设备可先与第一终端建立第一ACL链路；后续，如果可穿戴设备通过振动传感器检测到用户输入预设的敲击操作，可穿戴设备可根据保存的标识信息向N个终端(这N个终端中不包括第一终端，N≥1)发送测量信号；上述N个终端中接收到测量信号的M(1≤M≤N)个终端可反馈响应信号，使得可穿戴设备可接收到来自M个终端的M个响应信号，该响应信号与终端的RSSI关联；当终端的RSSI越大时，说明该终端距离可穿戴设备的距离越近，那么，可穿戴设备可将上述M个终端及第一终端中RSSI最大的终端确定为本次需要连接的第二终端；进而，可穿戴设备可断开与第一终端之间的第一ACL链路，建立与第二终端之间的第二ACL链路。
可以看出，用户通过执行一次简单的敲击操作，便可以触发可穿戴设备快速将蓝 牙连接设备从第一终端切换为第二终端，从而简化了设备之间建立蓝牙连接时的操作流程，提高了用户的使用体验。并且，上述方法无需对终端的硬件或软件进行修改，使得上述方法可适用现有的各类终端设备，从而提高了上述方法的使用场景。
在一种可能的实现方式中，上述测量信号为寻呼信号，例如，page request。
在一种可能的实现方式中，上述预设的敲击操作包括：用户使用手指或指关节敲击可穿戴设备的操作；用户使用可穿戴设备敲击第二终端的操作；或者，用户使用可穿戴设备敲击第二终端周围物体的操作。也就是说，在预设的敲击操作中敲击蓝牙耳机的对象可以为用户手指、指关节、需要切换的终端或需要切换的终端附近的任意物体，本申请实施例对此不做任何限制。
在一种可能的实现方式中，在可穿戴设备接收来自M个终端响应该测量信号产生的M个响应信号之后，还包括：可穿戴设备可分别计算上述M个响应信号中每个响应信号的信号强度，从而得到M个终端中每个终端的RSSI。或者，终端也可以在发送的响应信号中携带自身的RSSI，使得可穿戴设备可从每个终端发送的响应信号获取到对应终端的RSSI。
另外，可穿戴设备还可以基于上述第一ACL链路获取第一终端的RSSI。这样，可穿戴设备可在上述M个终端和第一终端中确定RSSI最大的第二终端。
第二方面，本申请提供一种建立通信连接的方法，包括：可穿戴设备通过振动传感器检测到用户输入预设的敲击操作；响应于该敲击操作，可穿戴设备可向N个终端发送测量信号，N＞1；上述N个终端中接收到测量信号的M(1≤M≤N)个终端可反馈响应信号，使得可穿戴设备接收到来自M个终端分别发送的M个响应信号，该响应信号与终端的信号强度关联；当终端的信号强度越大时，说明该终端距离可穿戴设备的距离越近，那么，可穿戴设备可将上述M个终端中信号强度最大的终端确定为本次需要连接的第一终端；进而，可穿戴设备与第一终端建立短距离无线通信连接。
也就是说，无论可穿戴设备是否已经与某一终端建立了短距离无线通信连接，可穿戴设备均可响应用户输入的敲击操作，检测到距离可穿戴设备最近的终端，并与该终端建立连接，从而简化了设备之间建立短距离无线通信连接时的操作流程，提高了用户的使用体验。
在一种可能的实现方式中，可穿戴设备通过振动传感器检测到用户输入预设的敲击操作，包括：可穿戴设备使用振动传感器采集接收到的振动信号；当该振动信号的振动特征与预设的敲击操作的振动特征相符时，可穿戴设备可确定用户输入了预设的敲击操作。
在一种可能的实现方式中，上述预设的敲击操作包括：用户使用手指或指关节敲击可穿戴设备的操作；用户使用可穿戴设备敲击第一终端的操作；或者，用户使用可穿戴设备敲击第一终端周围物体的操作。
在一种可能的实现方式中，可穿戴设备向N个终端发送测量信号，包括：可穿戴设备可按照这N个终端中每个终端的标识信息(例如配对信息)，向对应的终端发送测量信号。
在一种可能的实现方式中，可穿戴设备确定第一终端，包括：可穿戴设备可基于接收到的M个响应信号计算这M个终端中每个终端的信号强度(例如RSSI)；进而， 可穿戴设备可将信号强度最大的终端确定为第一终端。
在一种可能的实现方式中，上述信号强度是指：信号强度绝对值与预设的信号强度标准值之间的比值。
第三方面，本申请提供一种建立通信连接的方法，包括：终端通过振动传感器接收用户输入的第一敲击操作；当第一敲击操作为预设的敲击操作时，终端启动预设的进程开始等待测量信号；终端接收可穿戴设备发送的测量信号；响应于该测量信号，终端与可穿戴设备建立短距离无线通信连接。
也就是说，终端也可通过振动传感器检测到用户执行的敲击操作，那么，蓝牙耳机发送测量信号后无需再确定各个终端的信号强度，检测到敲击操作的终端可主动作为连接设备与蓝牙耳机建立蓝牙连接，从而缩短了蓝牙耳机连接终端时所耗费的时间。并且，用户通过执行一次简单的敲击操作，便可以触发蓝牙耳机快速地与相应的终端建立通信连接，从而简化了设备之间建立通信连接时的操作流程，提高了用户的使用体验。
在一种可能的实现方式中，上述预设的敲击操作为：用户使用可穿戴设备敲击终端的操作。
在一种可能的实现方式中，在终端通过振动传感器接收用户输入的第一敲击操作之后，还包括：当第一敲击操作的振动特征与预设的敲击操作的振动特征相符时，终端可确定第一敲击操作为预设的敲击操作。
在一种可能的实现方式中，在终端与可穿戴设备建立短距离无线通信连接之前，还包括：终端获取可穿戴设备采集到的第二敲击操作的振动信号；其中，终端响应测量信号自动与可穿戴设备建立短距离无线通信连接，包括：当第二敲击操作的振动信号与第一敲击操作的振动信号来自同一敲击操作时，说明用户使用蓝牙耳机敲击了该终端，即用户希望该终端作为蓝牙耳机的连接设备，此时，终端可与可穿戴设备建立短距离无线通信连接。
在一种可能的实现方式中，上述短距离无线通信连接可以为蓝牙连接，上述测量信号可以为寻呼信号。

具体实施方式
下面将结合附图对本实施例的实施方式进行详细描述。
示例性的，本申请实施例提供的一种建立通信连接的方法可应用图1所示的通信系统100中。通信系统100中可以包括可穿戴设备101以及一个或多个终端102。
其中，上述可穿戴设备101可以是无线耳机、智能手环、智能手表或智能眼镜等设备。上述终端102可以是手机、平板电脑、笔记本电脑、超级移动个人计算机(ultra-mobile personal computer，UMPC)、个人数字助理(personal digital assistant，PDA)等设备，本申请实施例对此不做任何限制。
在通信系统100中，可穿戴设备101可分别与上述一个或多个终端102建立短距离无线通信连接，实现可穿戴设备101与终端102之间的通信功能。例如，可穿戴设备101可与终端102建立蓝牙连接、Wi-Fi(wireless fidelity，无线保真)连接、ZigBee(紫蜂协议)连接或NFC(near field communication，近场通信)连接等通信连接。当然，可穿戴设备101还可以通过蜂窝网络互联或转接设备(例如，USB数据线或Dock设备)建立通信连接，本发明实施例对此不作任何限制。
如图2所示，可穿戴设备101中可设置振动传感器201。振动传感器201可用于检测可穿戴设备101产生的振动信号。例如，该振动传感器201可以为加速度传感器 或陀螺仪等，本申请实施例对此不做任何限制。
在本申请实施例中，用户可以通过可穿戴设备101与终端102产生敲击或碰撞的方式，触发可穿戴设备101自动与本次被敲击或被碰撞的终端102建立短距离无线通信连接。
例如，以蓝牙耳机为上述可穿戴设备101举例，一对蓝牙耳机可以包括左耳塞和右耳塞。以蓝牙耳机中的某一耳塞(例如左耳塞)为例，如图2所示，可以在左耳塞中设置振动传感器201，振动传感器201可用于采集左耳塞产生的振动信号。并且，可预先设置使用蓝牙耳机的左耳塞连续敲击某一终端102两下可触发蓝牙耳机与该终端102(例如手机A)建立蓝牙连接。
示例性的，可将左耳塞中的振动传感器201设置为常开状态(always on)，振动传感器201可持续采集左耳塞产生的振动信号。一般，在蓝牙耳机的左耳塞上执行两次敲击操作而导致左耳塞产生的振动信号通常具有固定的振动特征。例如，在左耳塞上执行两次敲击操作时，振动传感器201所产生的波形特征通常是一定的。因此，当振动传感器201采集到的振动信号符合预设的振动特征时，说明此时用户使用蓝牙耳机的左耳塞对某一终端敲击了两次，此时用户希望建立蓝牙耳机与被敲击的终端之间的蓝牙连接。
示例性的，蓝牙耳机内可存储有一个或多个终端的标识信息。例如，该标识信息可以是：已经与蓝牙耳机完成蓝牙配对的一个或多个终端的配对信息，例如，该配对信息可以包括终端的MAC(media access control，介质访问控制)地址、设备名称等标识。当检测到用户使用左耳塞执行了预设的敲击两次的操作后，蓝牙耳机可根据存储的各个终端的标识，向一个或多个终端102发送测量信号，以确定本次需要与蓝牙耳机建立蓝牙连接的连接设备。示例性的，如果蓝牙耳机中存储有手机A和手机B的配对信息，说明蓝牙耳机曾经与手机A和手机B均建立完成了蓝牙配对过程。那么，蓝牙耳机检测到用户执行了预设的敲击两次的操作后，可根据手机A的配对信息向手机A发送测量信号，并根据手机B的配对信息向手机B发送测量信号。例如，蓝牙耳机向手机A和手机B发送的测量信号具体可以为蓝牙设备发起的寻呼信号(page request)。
另外，现有的蓝牙设备中均保留有回连机制，即蓝牙设备的蓝牙功能开启后可自动回连最近一次的连接设备。例如，用户打开蓝牙耳机后，蓝牙耳机可自动回连最近一次连接的笔记本1。如果蓝牙耳机没有与笔记本1回连成功，且检测到用户执行了预设的敲击操作，则蓝牙耳机可按照上述方法根据终端的标识向各个终端发送测量信号。
仍以蓝牙耳机向手机A和手机B发送测量信号举例，手机A和手机B接收到蓝牙耳机发送的测量信号后，可向蓝牙耳机发送对应的响应信号，该响应信号可反映出发送方(即对应终端)的信号强度。例如，该响应信号可以为page response信号。例如，手机A可响应测量信号向蓝牙耳机发送第一响应信号，手机B可响应测量信号向蓝牙耳机发送第二响应信号。
一般，用户希望蓝牙耳机连接的设备为蓝牙耳机所敲击的终端。并且，用户使用蓝牙耳机敲击某一终端时该终端与蓝牙耳机之间的距离一般很近。而当蓝牙耳机接收 到的响应信号的信号强度越大时，发送该响应信号的终端的信号强度越大，说明蓝牙耳机与发送该响应信号的终端之间的距离越近。那么，蓝牙耳机可将信号强度最大的终端确定为本次需要与蓝牙耳机建立蓝牙连接的连接设备。例如，当上述第一响应信号的信号强度大于第二响应信号的信号强度时，说明手机A的信号强度大于手机B的信号强度，蓝牙耳机可将发送第一响应信号的手机A确定为本次需要与蓝牙耳机建立蓝牙连接的连接设备。进而，蓝牙耳机可按照标准的蓝牙协议建立蓝牙耳机与手机A之间的ACL(asynchronous connection less，异步无连接)链路，从而在蓝牙耳机与手机A之间实现蓝牙连接。
另外，在蓝牙耳机与其他终端(例如手机C)已经建立了蓝牙连接的场景下，用户也可以通过执行预设的敲击操作，触发蓝牙耳机按照上述方法将其连接设备从手机C切换为新的连接设备(例如手机A)。
也就是说，用户通过执行一次简单的敲击操作，便可以触发可穿戴设备快速与相应的连接设备建立短距离无线通信连接，从而简化了设备之间建立短距离无线通信连接时的操作流程，提高了用户的使用体验。并且，上述建立短距离无线通信连接的方法无需对连接设备的硬件或软件进行修改，使得上述建立短距离无线通信连接的方法可适用现有的各类终端设备，从而提高了上述短距离无线通信连接建立方法的使用场景。
进一步地，仍以蓝牙耳机为上述可穿戴设备101举例，该蓝牙耳机具体可以为真无线立体声(true wireless stereo，TWS)耳机，也可以是具有连接线的无线耳机等，本申请实施例对此不做任何限制。
如图2所示，蓝牙耳机的耳塞中除了上述振动传感器201之外，还可以包括处理器202、存储器203、无线通信模块204、音频模块205、受话器206、麦克风207以及电源208等。
其中，存储器203可以用于存储应用程序代码，如用于与蓝牙耳机的另一只耳塞建立无线连接，以及使得耳塞与上述终端102进行配对连接的应用程序代码。处理器202可以控制执行上述应用程序代码，以实现本申请实施例中蓝牙耳机的耳塞的功能。例如，实现测量蓝牙耳机与电子设备之间的链路的信道质量、待传输数据量等。
存储器203中还可以存储有用于唯一标识该耳塞的蓝牙地址，以及存储有蓝牙耳机的另一只耳塞的蓝牙地址。另外，该存储器203中还可以存储有与该耳塞之前成功配对过的终端102的配对历史。例如，该配对历史可以包括与该耳塞成功配对过的终端102的蓝牙地址。基于该配对历史，该耳塞能够自动回连至已配对的终端102。上述蓝牙地址可以为媒体访问控制(media access control，MAC)地址。
无线通信模块204，用于支持当前耳塞与蓝牙耳机的另一只耳塞以及与各种终端102之间的无线数据交换。在一些实施例中，该无线通信模块204可以为蓝牙收发器。蓝牙耳机的耳塞可以通过该蓝牙收发器与上述终端102之间建立无线连接，以实现两者之间的短距离数据交换。例如，交换音频数据、交换控制数据等。
音频模块205用于将数字音频信息转换成模拟音频信号输出，也用于将模拟音频输入转换为数字音频信号。音频模块205还可以包括编码器和解码器，用于对音频信号进行编码和解码。在一些实施例中，音频模块205可以设置于处理器202中，或将 音频模块205的部分功能模块设置于处理器202中。
至少一个受话器206，也可以称为“听筒”，可以用于将音频电信号转换成声音信号并播放。例如，当蓝牙耳机的耳塞作为上述终端102的音频输出设备时，受话器206可以将接收到的音频电信号转换为声音信号并播放。
至少一个麦克风207，也可以称为“话筒”，“传声器”，用于将声音信号转换为音频电信号。例如，当蓝牙耳机的耳塞作为上述终端102的音频输入设备时，在用户说话(如通话或发语音消息)的过程中，麦克风207可以采集用户的声音信号，并将其转换为音频电信号。上述音频电信号即为本申请实施例中的音频数据。
电源208，可以用于向蓝牙耳机的耳塞包含的各个部件供电。在一些实施例中，该电源208可以是电池，如可充电电池。通常，蓝牙耳机会配有一耳机盒。该耳机盒可以用于收纳蓝牙耳机的左右耳塞。该耳机盒可以用于收纳蓝牙耳机的左耳塞和右耳塞。在一些实施例中，该耳机盒上可以设置有至少一个触摸控件，可以用于触发蓝牙耳机与终端102重新配对等操作。该耳机盒上还可以设置有充电口，用于耳机盒自身进行充电。又例如，该耳机盒还可以为蓝牙耳机的左右耳塞充电。可以理解的是，该耳机盒上还可以包括其他控件，此处不再一一说明。
可以理解的是，本申请实施例示意的结构并不构成对蓝牙耳机的具体限定。其可以具有比图2中所示出的更多的或者更少的部件，可以组合两个或更多的部件，或者可以具有不同的部件配置。例如，蓝牙耳机中还可以包括：距离传感器、接近光传感器、指示灯(可以指示耳塞的电量等状态)、显示屏(可以提示用户相关信息)、防尘网(可以配合听筒使用)、马达等部件。图2中所示出的各种部件可以在包括一个或多个信号处理或专用集成电路在内的硬件、软件、或硬件和软件的组合中实现。

以下，将结合附图对本申请实施例提供的一种建立通信连接的方法进行具体介绍。以下实施例中均以蓝牙耳机作为上述可穿戴设备101，并以蓝牙耳机的配对设备包括手机A和手机B举例说明。
图4为本申请实施例提供的一种建立通信连接的方法的流程示意图。如图4所示，该方法可以包括：
S401、蓝牙耳机播放来自手机A的音频内容，蓝牙耳机与手机A已建立蓝牙连接。
示例性的，当用户希望使用蓝牙耳机播放手机A中的音频内容时，可开启蓝牙耳机以及手机A中的蓝牙功能，并建立手机A与蓝牙耳机之间的蓝牙连接。例如，如图5所示，手机A可在蓝牙功能的设置界面501中显示曾经连接过的蓝牙设备列表。蓝牙设备列表中的一个或多个蓝牙设备均为曾经与手机A完成蓝牙配对的蓝牙设备。手机A每次与新的蓝牙设备配对成功后，手机A可将该蓝牙设备添加至上述蓝牙设备列表中。并且，手机A可存储每个已配对的蓝牙设备的配对信息，即蓝牙设备的标识信息。例如，该配对信息可以包括蓝牙设备的名称、蓝牙设备的MAC地址等，本申请实施例对此不做任何限制。
如果蓝牙耳机位于手机A显示的上述蓝牙设备列表中，则用户打开蓝牙耳机后，可在上述设置界面501中选择该蓝牙耳机(例如上述蓝牙设备列表中“我的耳机”这一选项)。进而，手机A可根据已保存的蓝牙耳机的配对信息，向蓝牙耳机发送寻呼信号(page request)。蓝牙耳机接收到手机A发来的page request后，由于蓝牙耳机中也存储有手机A的配对信息，因此，蓝牙耳机可向手机A发送对应的响应信号(page response)。手机A接收到蓝牙耳机发来的page response后，可与蓝牙耳机建立第一ACL链路，实现手机A与蓝牙耳机之间的蓝牙连接。
当然，如果手机A未曾与蓝牙耳机建立过蓝牙连接，则手机A搜索到该蓝牙耳机后可先与蓝牙耳机进行配对，再按照上述蓝牙连接的建立流程与蓝牙耳机建立蓝牙连接，本申请实施例对此不做任何限制。
蓝牙耳机与手机A建立了蓝牙连接后，手机A可作为蓝牙耳机的连接设备，向蓝牙耳机输出手机A中的音频内容，由蓝牙耳机向用户播放该音频内容。
S402、蓝牙耳机检测到用户输入预设的敲击操作。
在蓝牙耳机播放手机A中音频内容的同时，如果用户希望将该蓝牙耳机的连接设备从手机A切换为手机B，则如图6所示，用户可使用蓝牙耳机(例如一对蓝牙耳机中的左耳塞或右耳塞)对手机B执行预设的敲击操作。在一些实施例中，该预设的敲击操作可以为用户使用蓝牙耳机敲击等待连接的终端(例如手机B)的操作。例如，该预设的敲击操作具体可以为使用蓝牙耳机连续敲击两下手机B的操作。该预设的敲击操作用于触发蓝牙耳机将其连接设备从已连接的手机A切换为手机B。
示例性的，蓝牙耳机中可设置加速度传感器等振动传感器。蓝牙耳机开启后，蓝牙耳机可控制加速度传感器以一定的工作频率采集当前的振动信号。进而，蓝牙耳机可实时从采集到的振动信号中提取对应的振动特征。如果某一时间提取到的振动特征与预设的敲击操作的振动特征相符，则蓝牙耳机可确定用户此时输入了预设的敲击操作。
例如，蓝牙耳机可从采集到的振动信号中实时提取对应的振动波形。蓝牙耳机可使用预设的波形算法分析提取到的振动波形是否为蓝牙耳机连续敲击两下产生的振动波形。如果取到的振动波形是蓝牙耳机连续敲击两下产生的振动波形，则蓝牙耳机可确定用户此时使用蓝牙耳机向某一终端连续敲击了两下。进而，蓝牙耳机可通过执行下述步骤S403-S404确定蓝牙耳机需要切换的新的连接设备。
在另一些实施例中，除了将使用蓝牙耳机敲击其他终端作为预设的敲击操作外，还可以将用户手指或指关节敲击蓝牙耳机的操作设置为预设的敲击操作。也就是说，当用户希望更换蓝牙耳机的连接设备时，用户无需摘下耳机，可直接在佩戴的蓝牙耳机上执行预设的敲击操作(例如指关节敲击蓝牙耳机一下)，从而触发蓝牙耳机通过执行下述步骤S403-S404确定蓝牙耳机需要切换的新的连接设备。
又或者，如果用户希望将该蓝牙耳机的连接设备从手机A切换为手机B，用户还可以使用蓝牙耳机在手机B附近执行敲击操作，例如，使用蓝牙耳机敲击手机B附近的桌面两下。此时，上述预设的敲击操作是指用户使用蓝牙耳机在需要连接的终端附近执行的敲击操作。同样，蓝牙耳机检测到该预设的敲击操作后，可通过执行下述步骤S403-S404确定蓝牙耳机需要切换的新的连接设备。
可以看出，在预设的敲击操作中敲击蓝牙耳机的对象可以为用户手指、指关节、需要切换的终端或需要切换的终端附近的任意物体，本申请实施例对此不做任何限制。
S403、响应于上述敲击操作，蓝牙耳机向手机B发送测量信号。
蓝牙耳机检测到用户输入了预设的敲击操作后，说明用户希望更换蓝牙耳机当前的连接设备。但此时蓝牙耳机无法确定用户希望更换的新的连接设备具体是哪一个终端。
对此，在步骤S403中，为了确定蓝牙耳机此时需要更换的连接设备，蓝牙耳机可向已配对的一个或多个蓝牙设备分别发送测量信号。与图5中所示的手机A的蓝牙设备列表类似的，蓝牙耳机中也可存储已配对的一个或多个蓝牙设备的配对信息。以蓝牙耳机中保存有手机B的配对信息举例，为了确定此时蓝牙耳机需要更换的连接设备，蓝牙耳机可根据手机B的配对信息向手机B发送测量信号。例如，该测量信号可以为寻呼信号(page request)。
当然，如果蓝牙耳机中还保存有手机C等其他终端的标识信息，则蓝牙耳机也可根据其标识信息向这些终端发送测量信号。另外，由于蓝牙耳机已经与手机A建立了蓝牙连接，蓝牙耳机能够通过该蓝牙耳机与手机A交互从而获取到手机A的信号强度等信息，因此，蓝牙耳机检测到上述敲击操作后，无需向手机A发送测量信号。
示例性的，蓝牙耳机可按照建立ACL链路的流程，向手机B发送寻呼信号(page request)，该寻呼信号即为上述测量信号。同时，手机B开启蓝牙功能后可以接收到其他设备发来的寻呼信号。
那么，手机B接收到蓝牙耳机发来的寻呼信号(即测量信号)后，可响应该寻呼信号向蓝牙耳机发送page response(即响应信号)。进而，蓝牙耳机可继续执行下述步骤S404-S405。
S404、蓝牙耳机确定手机A和手机B的信号强度。
S405、若手机B的信号强度最大，则蓝牙耳机断开与手机A之间的蓝牙连接，与手机B建立蓝牙连接。
在步骤S404中，蓝牙耳机接收到其他蓝牙设备(例如上述手机B)发来的响应信号后，由于手机B发来的响应信号与手机B的信号强度是关联的，因此，蓝牙耳机可根据该响应信号确定手机B的信号强度，例如，手机B的RSSI(received signal strength indication，信号强度指示)。例如，蓝牙耳机可基于手机B发来的响应信号按照预设的公式计算手机B的RSSI。又或者，如果手机B发来的响应信号中携带有手机B的RSSI，则蓝牙耳机可从该响应信号的预设字段中获取手机B的RSSI。
并且，由于蓝牙耳机与手机A之间已经建立有蓝牙连接，因此，蓝牙耳机可基于该蓝牙连接获取手机A的信号强度，例如，手机A的RSSI。
当用户使用蓝牙耳机在新的连接设备上执行了预设的敲击操作时，蓝牙耳机与该新的连接设备之间的距离一般较近。当两个设备的距离越近时，两个设备进行信号交互时的信号强度也会相应增大。相应的，当两个设备的距离越远时，两个设备进行信号交互时信号强度的衰减逐渐增大。如表1所示，以设备1向设备2发送信号举例，设备1的信号发射功率F为2400Hz。当设备1与设备2之间的距离从0.1m增加至1m的过程中，设备1发送的信号的衰减值逐渐增大，即设备1发送的信号强度逐渐减小。
表1
说明 Los(衰减值/dB) D(距离/m) F(发射功率/Hz)
0.1m的衰减 20.04422483 0.1 2400
0.2m的衰减 26.06482475 0.2 2400
0.3m的衰减 29.58664993 0.3 2400
0.4m的衰减 32.08542466 0.4 2400
0.5m的衰减 34.02362492 0.5 2400
1.0m的衰减 40.04422483 1.0 2400
蓝牙耳机接收到一个或多个蓝牙设备发来的响应信号后，可分别获取每个响应信号的信号强度，从而得到与每个响应信号对应的每个蓝牙设备的信号强度。并且，蓝牙耳机可从已连接的手机A中获取手机A的信号强度。进而，蓝牙耳机可在这多个蓝 牙设备中将信号强度最大的蓝牙设备确定为新的连接设备。
在另一些实施例中，上述响应信号除了可以为page response外，还可以为BLE(bluetooh low energy，蓝牙低功耗)广播。示例性的，如果手机A和手机B为BLE蓝牙设备，则手机A和手机B可基于BLE协议周期性的以BLE广播的形式发送advertising data(广播数据)。advertising data用于指示当前BLE蓝牙设备处于可被连接的状态。那么，蓝牙耳机接收到手机A和手机B发来的advertising data后，可分别计算手机A和手机B发来的advertising data的信号强度，从而确定出手机A和手机B的信号强度。进而，蓝牙耳机可将信号强度最大的蓝牙设备确定为新的连接设备。
示例性的，蓝牙耳机接收到手机B发来的响应信号后，可计算该响应信号的RSSI。蓝牙耳机可将该响应信号的RSSI作为手机B的RSSI。并且，蓝牙耳机可从手机A中获取手机A的RSSI。或者，蓝牙耳机可根据手机A发来的蓝牙信号计算手机A的RSSI。如果检测到手机B的RSSI大于手机A的RSSI，说明蓝牙耳机与手机B的距离更近，用户很可能使用蓝牙耳机在手机B上执行了预设的敲击操作。进而，蓝牙耳机可将手机B确定为本次需要建立蓝牙连接的连接设备。
那么，在步骤S405中，蓝牙耳机可断开与手机A之间已建立的第一ACL链路，并建立与手机B之间的第二ACL链路，即将蓝牙耳机的连接设备从手机A切换为手机B。这样，用户便可使用蓝牙耳机基于第二ACL链路播放手机B中的音频内容。
相应的，如果检测到手机A的RSSI大于手机B的RSSI，说明用户很可能使用蓝牙耳机在手机A上执行了预设的敲击操作。但由于蓝牙耳机已经与手机A建立了第一ACL链路，因此，蓝牙耳机可继续保持与手机A之间的第一ACL链路，无需切换当前的连接设备。
在另一些实施例中，不同蓝牙设备在向蓝牙耳机发送上述响应信号时设置的信号发射功率可能不同，那么，在一些场景中，虽然手机A向蓝牙耳机发送的第一响应信号的信号强度大于手机B向蓝牙耳机发送的第二响应信号的信号强度，但由于手机A的信号发射功率大于手机B的信号发射功率，因此，在手机A与蓝牙耳机的距离大于手机B与蓝牙耳机的距离时，蓝牙耳机接收到的第一响应信号的信号强度也有可能大于第二响应信号的信号强度。这样一来，蓝牙耳机根据信号强度的实测值确定出的连接设备可能存在不准确的情况。
对此，蓝牙耳机获取到与各个响应信号对应的信号强度的实测值后，可以计算各个响应信号的相对信号强度，进而将相对信号强度最大的响应信号所对应的蓝牙设备确定为新的连接设备。其中，相对信号强度是指：信号强度的实测值与预设的信号强度标准值之间的比值。一般，不同类型或不同型号的设备的信号强度标准值是不同的。示例性的，该信号强度标准值可以是该设备标称的最大信号强度，也可以是实际检测出的该设备的最大信号强度。
例如，手机A发射的信号强度标准值为1000dBm，手机B发射的信号强度标准值为800dBm。如果检测到手机A发送的第一响应信号的信号强度(即第一响应信号强度的实测值)为600dBm，则第一响应信号的相对信号强度＝600dBm/1000dBm＝0.6。如果检测到手机B发送的第二响应信号的信号强度(即第二响应信号强度的实测值)为500dBm，则第二响应信号的相对信号强度＝500dBm/800dBm＝0.625。
可以看出，虽然第一响应信号强度的实测值(600dBm)大于第二响应信号强度的实测值(500dBm)，但第一响应信号的相对信号强度(0.6)小于第二响应信号的相对信号强度(0.625)，实际手机B与蓝牙耳机之间的距离更近。因此，蓝牙耳机可确定发送第二响应信号的手机B为新的连接设备。
其中，各个设备或各类设备的信号强度标准值可预先存储在蓝牙耳机中。这样，蓝牙耳机检测出每个响应信号的信号强度的实测值后，可查找对应的信号强度标准值，进而计算该响应信号的相对信号强度。这样，通过对比不同响应信号的相对信号强度，蓝牙耳机可以更加准确的确定出本次需要建立蓝牙连接的连接设备。
在本申请的另一些实施例中，还可以在蓝牙耳机所敲击的设备(例如上述手机A或手机B)中设置振动传感器。这样，用户使用蓝牙耳机向新的连接设备(例如手机B)输入预设的敲击操作时，不仅蓝牙耳机可以检测到该敲击操作，手机B也可检测到该敲击操作。那么，手机B也可主动与蓝牙耳机建立蓝牙连接，从而缩短建立或切换蓝牙连接时的耗时。
示例性的，如图7所示，本申请实施例提供的一种建立通信连接的方法包括：
S701、蓝牙耳机播放来自手机A的音频内容，蓝牙耳机与手机A已建立蓝牙连接。
与步骤S401类似的，在步骤S701中，用户可将手机A作为蓝牙耳机的连接设备，建立手机A与蓝牙耳机之间的第一ACL链路。进而，用户可使用蓝牙耳机基于第一ACL链路播放手机A中的音频内容。
S702、蓝牙耳机检测到用户输入预设的敲击操作。
示例性的，用户可使用蓝牙耳机对需要切换的连接设备输入预设的敲击操作，以触发蓝牙耳机与新的连接设备建立蓝牙连接。
与步骤S402类似的，在步骤S702中，蓝牙耳机中设置有振动传感器，蓝牙耳机可使用该振动传感器采集蓝牙耳机上产生的振动信号。并且，蓝牙耳机可从采集到的振动信号中提取对应的振动特征。如果某一时间提取到的振动特征与预设的敲击操作的振动特征相符，则蓝牙耳机可确定用户此时输入了预设的敲击操作，说明用户此时希望将蓝牙耳机连接至新的连接设备中。
S703、手机B检测到用户输入预设的敲击操作。
在步骤S703中，还可以在蓝牙耳机的候选连接设备(例如手机B)中设置上述振动传感器。这样，当用户可使用蓝牙耳机对手机B输入预设的敲击操作时，手机B中的振动传感器也可以采集到相应的振动信号。进而，手机B也可以从采集到的振动信号中提取对应的振动特征。如果提取到的振动特征与预设的敲击操作的振动特征相符，则手机B可确定用户此时输入了预设的敲击操作，说明用户此时希望将手机B作为蓝牙耳机的连接设备与蓝牙耳机连接。
手机B检测到用户输入预设的敲击操作后，可将该敲击操作上报给应用层中蓝牙功能的相关应用。进而，该应用可启动预设的进程将手机B设置为主设备(Master)，等待其他蓝牙设备发来的寻呼信号触发手机B主动与其他蓝牙设备建立蓝牙连接。
S704、响应于上述敲击操作，蓝牙耳机向手机B发送寻呼信号。
与步骤S403类似的，在步骤S704中，蓝牙耳机检测到用户输入了预设的敲击操作后，可按照现有的蓝牙连接的建立流程，根据保存的一个或多个蓝牙设备的标识信 息(例如配对信息)向对应的蓝牙设备发送寻呼信号。
以蓝牙耳机保存有手机B的配对信息举例，蓝牙耳机检测到用户输入了预设的敲击操作后，可根据手机B的配对信息向手机B发送寻呼信号(page request)。
S705、响应于上述寻呼信号，手机B自动与蓝牙耳机建立蓝牙连接。
在步骤S705中，由于在步骤S703中手机B通过检测预设的敲击操作已经确定出有其他设备需要与自身(即手机B)建立通信连接，手机B以切换为主设备模式等待接收寻呼信号。那么，手机B接收到蓝牙耳机发来的寻呼信号后，可确定本次需要与手机B建立通信连接的设备为蓝牙耳机。相应的，其他接收到寻呼信号的蓝牙设备由于在接收到寻呼信号之前并没有检测到用户输入预设的敲击操作，因此，这些蓝牙设备在接收到蓝牙耳机发来的寻呼信号之后可以不响应该寻呼信号。
进而，手机B可作为主设备(master)与蓝牙耳机建立第二ACL链路，实现蓝牙耳机与手机B之间的蓝牙连接。手机B与蓝牙耳机建立蓝牙连接时，蓝牙耳机可自动断开与手机A之间的第一ACL链路。
在一些实施例中，为了避免手机B接收到寻呼信号后与错误的蓝牙设备建立蓝牙连接，手机B在接收到蓝牙耳机发来的寻呼信号后，还可以从蓝牙耳机中获取用户输入上述预设的敲击操作时产生的振动信号或振动特征。进而，手机B可对比手机B产生的振动信号(即第一振动信号)与蓝牙耳机产生的振动信号(即第二振动信号)，从而判断这两个振动信号是否为同一敲击操作产生的。例如，当手机B产生的振动信号与蓝牙耳机产生的振动信号相同时，可确定这两个振动信号来自同一敲击操作。如果判断出这两个振动信号来自同一敲击操作，说明用户希望手机B连接的设备为该蓝牙耳机，则手机B可主动与蓝牙耳机建立蓝牙连接，从而将蓝牙耳机的连接设备从手机A切换为手机B。
在上述建立通信连接的方法中，由于蓝牙耳机的各个候选连接设备也可以检测到用户更换连接设备时执行的敲击操作，因此，蓝牙耳机无需对多个候选连接设备的信号强度进行测量和计算，检测到敲击操作的候选连接设备可主动作为新的连接设备与蓝牙耳机建立蓝牙连接，从而缩短了蓝牙耳机切换连接设备时所耗费的时间。并且，用户通过执行一次简单的敲击操作，便可以触发蓝牙耳机快速地与相应的连接设备建立通信连接，从而简化了设备之间建立通信连接时的操作流程，提高了用户的使用体验。
需要说明的是，上述实施例中是以蓝牙耳机作为可穿戴设备举例，以蓝牙耳机在手机A和手机B中切换连接设备为应用场景举例说明的。可以理解的是，上述建立通信连接的方法可应用在多种可穿戴设备以及多种应用场景中。
例如，如图8中的(a)所示，蓝牙耳机与手机A建立蓝牙连接后，蓝牙耳机的蓝牙连接状态处于一个稳定状态。如果用户希望将蓝牙耳机的连接设备切换为笔记本B，如图8中的(b)所示，用户可使用蓝牙耳机在笔记本B上执行预设的敲击操作。与上述实施例类似的，蓝牙耳机可响应该敲击操作确定本次需要更换的连接设备为笔记本B，此时，蓝牙耳机的蓝牙连接状态处于切换状态中。进而，如图8中的(c)所示，蓝牙耳机可与新的连接设备(即笔记本B)建立蓝牙连接，蓝牙耳机的蓝牙连接状态再次切换到一个稳定状态。
又例如，在蓝牙耳机与手机A已建立蓝牙连接时，如果用户在汽车内希望使用蓝牙耳机播放车载设备中的音频内容，则用户可使用蓝牙耳机在车载设备上执行预设的敲击操作。同样，蓝牙耳机可响应该敲击操作确定本次需要更换的连接设备为车载设备，进而与车载设备建立蓝牙连接。
又例如，对于智能手环、智能手表以及智能眼镜等可穿戴设备，这些可穿戴设备在工作时通常作为从设备与手机等主设备通过蓝牙或Wi-Fi建立通信连接。那么，也可按照上述实施例中所述的方法，通过对可穿戴设备执行预设的敲击操作，触发可穿戴设备与不同的主设备建立通信连接。
另外，除了可穿戴设备外，手机、平板电脑、音箱、笔记本电脑等终端也可按照上述方法与其他终端通过蓝牙或Wi-Fi建立通信连接。例如，用户的手机中可设置上述振动传感器。当用户希望手机与蓝牙音箱建立蓝牙连接时，可使用手机对蓝牙音箱执行预设的敲击操作。进而，手机检测到该敲击操作后，可按照上述实施例中所述的方法确定出手机需要连接的设备为蓝牙音箱，进而，手机可自动与蓝牙音箱建立蓝牙连接。这样，用户通过执行一次简单的敲击操作，便可以触发两个设备快速的建立通信连接，从而简化了设备之间建立通信连接时的操作流程，提高了用户的使用体验。
