背景技术
蓝牙(Bluetooth，BT)技术是一种无线数据通信的开放性全球规范，它以低成本的近距离无线连接为基础，是当今市场上支持范围最广泛、功能最丰富且安全的近场无线通信标准。
目前的蓝牙技术主要包括基本速率(basic rate，BR)蓝牙技术和增强数据速率(enhanced data rate，EDR)蓝牙技术。并且目前的电子设备也都是单模的蓝牙通信设备，即仅支持BR/EDR的蓝牙连接方式。由于BR/EDR主要是用于传输一些数据量较大的数据，如音频数据等，在电子设备之间需要通过蓝牙连接传输一些数据量较小的数据(例如，用户的心率、血压等数据)时，采用BR/EDR的连接方式会造成电子设备功耗的浪费。

为了便于理解，本申请以下实施例将以具有图1和图2所示结构的手机，以及图3所示的蓝牙耳机为例，结合附图对本申请实施例提供的蓝牙配对连接的方法进行具体阐述。
图4示出了本申请实施例提供的一组图形用户界面(graphical user interface，GUI)。图4示出了蓝牙耳机通过靠近发现和手机连接的过程。
参见图4中的(a)所示，手机处于亮屏状态且显示手机桌面。其中，手机桌面包括支付宝应用、任务卡商店、微博、相册、微信、卡包、设置和主题等应用程序(application，APP)。蓝牙耳机此时处于耳机盒中。
参见图4中的(b)所示，当蓝牙耳机检测到用户打开耳机盒且，靠近手机后，手机会自动弹出提醒框401，其中提醒框401中可以显示蓝牙耳机的设备名称，当手机检测到用户点击控件402的操作后，手机可以和蓝牙耳机进行配对。
图5示出了本申请实施例的手机和蓝牙耳机进行蓝牙配对连接的方法500的示意性流 程图，如图5所示，该方法500包括：
S501，蓝牙耳机检测到用户打开耳机盒的操作后。
S502，响应于检测到用户打开耳机盒的操作，主耳和副耳之间先建立基本速率(basic rate，BR)/增强数据速率(enhanced data rate，EDR)链路(或者，左耳和右耳之间先建立BR/EDR链路)。
S503，蓝牙耳机确定主耳，主耳可以向周围的设备发送BLE广播数据包。
示例性的，该BLE广播数据包中可以携带主耳的MAC地址以及蓝牙耳机的设备类型。
应理解，本申请实施例中，主耳可以根据预定义规则确定。该预定义规则可以为静态配置与动态配置结合的方式。
例如，蓝牙耳机中左耳的MAC地址为MAC地址1，右耳的MAC地址为MAC地址2。蓝牙耳机在开盒前可以先静态配置右耳为主耳，则上述BLE广播中可以携带MAC地址2以及蓝牙耳机的设备类型。当手机接收到该BLE广播数据包后，可以解析出其中的MAC地址为MAC地址2，手机就会始终以MAC地址2和蓝牙耳机建立BR/EDR连接。
当蓝牙耳机检测到用户开盒的操作后，蓝牙耳机可以动态配置主耳的确定方式。
例如，蓝牙耳机可以根据左耳和右耳的位置确定谁是主耳谁是副耳。当蓝牙耳机检测到左耳插入用户的耳中，右耳还没有插入用户的耳中时，蓝牙耳机可以确定左耳为主耳，右耳是副耳。此时左耳和右耳之间已经建立BR/EDR链路，也就是说左耳知道右耳的MAC地址，右耳也知道左耳的MAC地址。那么左耳就可以使用MAC地址2和手机建立BR/EDR链路，右耳可以监听(或者，侦听)手机和左耳之间的链路。
在左耳和右耳都插入用户耳中的情况下，蓝牙耳机还可以根据左耳和右耳的电量来判断谁是左耳谁是右耳。例如，在左耳和右耳都插入用户耳中的情况下，右耳的电量比左耳的电量高，那么蓝牙耳机可以确定右耳为主耳，左耳为副耳，那么右耳可以使用MAC地址2和手机建立BR/EDR链路，左耳可以监听(或者，侦听)手机和右耳之间的链路。
S504，手机接收到该BLE广播数据包后，显示蓝牙耳机的设备类型以及提醒用户是否需要将手机和蓝牙耳机建立连接。
示例性的，如图4中的(b)所示，手机的显示屏上可以显示蓝牙耳机的设备类型以及控件402。

S506，蓝牙耳机处于寻呼扫描(page scan)时，接收到手机发送的page，手机和主耳建立(BR/EDR)ACL链接。
S507，手机和主耳之间进行(BR/EDR)配对/SDP/加密过程。
应理解，S505和S506可以理解为手机和主耳之间进行标准蓝牙配对的流程。
S508，手机和主耳之间进行数据传输。

S702，响应于用户打开耳机盒的操作，左耳和右耳建立BR/EDR链路。
S703，蓝牙耳机检测到用户按压耳机盒上的功能键，主耳进入查询扫描(inquiry scan)。
应理解，手机检测到用户按压功能键进入可配对模式后，主机(host)给控制器(controller)发送指令，使得控制器进入可配对模式。
S704，手机检测到用户打开蓝牙功能。
示例性的，如图6中的(c)所示，当手机检测到用户点击蓝牙功能603的操作后， 手机打开蓝牙。
S705，手机向周围的设备发送查询(inquiry)消息。
S706，主耳响应于手机发送的inquiry，向手机发送FHS包，其中，FHS包中包括主耳的MAC地址。
应理解，主耳的确定过程可以参考上述方法500中的描述，为了简洁，在此不再赘述。
S707，手机针对该FHS包中的MAC地址，向主耳发送请求信息，该请求信息用于请求蓝牙耳机的设备名。
S708，响应于该请求信息，主耳向手机发送该蓝牙耳机的设备名。
S709，手机在蓝牙设备搜索界面中的可用设备中显示该蓝牙耳机的设备名。
示例性的，如图6中的(f)所示，该蓝牙耳机的设备名可以为“蓝牙耳机”。
S710，手机检测到用户点击“蓝牙耳机”的操作。
S711，响应于用户点击“蓝牙耳机”的操作，手机针对该蓝牙耳机的MAC地址发起寻呼(page)。
S712，主耳处于寻呼扫描(page scan)状态下，接收到手机发送的page后，手机和主耳机建立ACL链接。
S713，手机和主耳之间进行(BR/EDR)配对/SDP/加密过程。
应理解，S712和S713可以理解为手机和主耳之间进行标准蓝牙配对的流程。
S714，手机和主耳之间进行数据传输。
示例性的，当手机通过蓝牙耳机接听电话时，手机和主耳之间可以进行HFP连接。
示例性的，当手机通过蓝牙耳机听音乐，看视频时，手机和主耳之间可以进行A2DP连接。
应理解，以上方法700介绍了手机主动查询蓝牙耳机并建立连接的过程。
以上结合方法500和方法700介绍了手机和蓝牙耳机建立连接的过程。目前，手机和蓝牙耳机建立的连接可以为BR/EDR连接，也就是手机只和主耳建立BR/EDR连接，副耳可以监听(或者，侦听)手机和主耳之间的链路。
对于仅支持BR/EDR模式的手机和蓝牙耳机来说，手机和蓝牙耳机可以建立BR/EDR连接后进行正常的数据传输。本申请实施例中给出了另一种BLE模式的连接方式，对于支持BR/EDR和BLE的手机和蓝牙耳机来说，可以通过建立BR/EDR连接，在识别对端设备的类型和能力后，选择后续连接是基于BR/EDR模式还是基于BLE模式。
图8示出了本申请实施例提供的手机和蓝牙耳机进行蓝牙配对连接的方法800的示意性流程图，如图8所示，该方法800包括：
S801，手机和蓝牙耳机通过第一模式建立连接。
示例性的，该第一模式可以为BR/EDR模式。
应理解，这里手机和蓝牙耳机进行BR/EDR连接的建立过程可以参考上述方法500和方法700中的描述，为了简洁，在此不再赘述。
还应理解，该第一模式下，手机其实是和蓝牙耳机的主耳建立连接。
S802，在手机确定蓝牙耳机支持双模，且手机本身也支持双模时，手机和蓝牙耳机通过第二模式建立连接。
一个实施例中，手机和蓝牙耳机通过第二模式建立连接之间，手机和蓝牙耳机断开第 一模式的连接。
本申请实施例中以第二模式优先于第一模式，手机在通过BR/EDR建立ACL链路后就可以询问蓝牙耳机是否支持双模，如果手机和蓝牙耳机都支持双模，那么手机和蓝牙耳机可以建立BLE连接。
示例性的，手机和配件设备(例如，手表，手环等)都支持双模，那么手机可以和配件设备通过BLE连接传输心率、血压等等数据，这样可以节省手机和配件设备的功耗。或采用BLE扩展的传输协议进行音频数据、视频数据或者通话数据的传送。
那么对于手机支持双模，但是配件设备不支持双模；或者，手机不支持双模，但是配件设备支持双模的情况下，手机可以在通过BR/EDR建立ACL链路后，继续进行(BR/EDR)配对/SDP/加密等等操作，从而手机和配件设备建立BR/EDR连接后再传输数据。
应理解，若手机不支持双模，或者手机支持双模但是蓝牙耳机不支持双模，或者手机不支持双模但是蓝牙耳机支持双模时，手机可以和蓝牙耳机之间继续保持通过第一模式建立连接。
还应理解，在该第二模式下，手机其实分别和蓝牙耳机的主耳和副耳建立BLE连接，或者说手机分别和蓝牙耳机的左耳和右耳建立BLE连接。
本申请实施例中，BLE模式相比于BR/EDR模式，更有助于节省电子设备的功耗。
下面对本申请实施例的BLE模式进行说明。
图9是示出了本申请实施例提供的手机和蓝牙耳机进行蓝牙配对连接的方法900的示意性流程图，如图9所示，该方法900包括：
S901，手机和蓝牙耳机通过第一模式建立连接。
示例性的，该第一模式可以为BR/EDR模式。手机其实是和主耳建立BR/EDR连接。
应理解，这里手机和蓝牙耳机进行BR/EDR连接的建立过程可以参考上述方法500和方法700中的描述，为了简洁，在此不再赘述。
S902，手机向蓝牙耳机发送能力查询请求信息，该能力查询请求信息用于查询蓝牙耳机是否支持双模。
示例性的，手机向主耳发送能力查询请求信息。
示例性的，手机通过echo向蓝牙耳机发送查询请求信息。例如，手机可以向蓝牙耳机发送回声请求echo request消息，在echo request消息中携带能力查询请求信息；蓝牙耳机可以向手机发送回声响应echo response消息，在echo response消息携带能力查询响应信息。
应理解，S902可以是在S901手机和蓝牙耳机已经建立BR/EDR连接的情况下进行的能力查询。也可以是S901中手机和蓝牙耳机建立BR/EDR的过程中，当手机和主耳之间建立ACL链路后，手机就可以向蓝牙耳机发送该能力查询请求信息，这样手机可以在和主耳建立好BR/EDR的协议和profile之前就确定蓝牙耳机是否支持双模，如果手机确定蓝牙耳机支持双模，那么这样可以避免后续BR/EDR连接建立的过程，快速切换到BLE连接，有助于节省手机和蓝牙耳机建立BLE连接的时延。
S903，主耳向手机发送能力查询响应信息，该能力查询响应信息用于指示该蓝牙耳机支持双模。
示例性的，主耳向手机发送该能力查询响应信息。
S904，手机向主耳查询主耳和副耳的真实的MAC地址。
示例性的，蓝牙耳机的左耳的MAC地址为MAC地址1，右耳的MAC地址为MAC地址2。在BR/EDR模式下，蓝牙耳机在开盒前可以先静态配置主耳为右耳，那么蓝牙耳机在开盒后就会使用MAC地址2与手机建立BR/EDR连接。
在蓝牙耳机检测到用户开盒后，蓝牙耳机还可以通过位置和电量来动态调整主耳。例如，蓝牙耳机在确定左耳在用户的耳中，右耳不在用户的耳中，那么可以确定左耳为主耳。由于开盒后，左耳和右耳之间会建立连接，所以左耳其实也知道右耳的MAC地址，那么左耳可以使用MAC地址2和手机建立BR/EDR连接。
示例性的，蓝牙耳机可以具备佩戴检测功能，例如，蓝牙耳机可以通过接近光传感器检测耳机的位置。在动态地址变换的过程中通过接近光传感器检测检测左耳或者右耳的位置。接近光传感器可以确定左耳或者右耳是否位于用户的耳中，或者接近光传感器可以确定左耳或者右耳是否从用户的耳中脱落。
又例如，左耳和右耳都在用户的耳中，那么蓝牙耳机可以根据左耳和右耳的电量来确定主耳。若右耳的电量高于左耳，那么蓝牙耳机可以确定右耳为主耳，此时，右耳可以使用MAC地址2与手机建立BR/EDR连接。
在BLE模式下，对于手机而言，手机保存有MAC地址2这一地址信息，那么手机可以针对MAC地址2向主耳查询主耳和副耳的MAC地址。
S905，主耳向手机发送主耳和副耳真实的MAC地址。
示例性的，若右耳位于用户的耳中，左耳不再用户的耳中，此时右耳为主耳。那么其实是主耳(右耳)可以通过MAC地址2和手机建立ACL链路，手机向主耳(右耳)询问是否支持双模。若主耳(右耳)返回的能力查询响应信息中指示支持双模，那么手机会接着向主耳(右耳)查询MAC地址信息。主耳(右耳)会向手机返回其真实的MAC地址为MAC地址2，以及对耳(左耳)的MAC地址为MAC地址1。
应理解，手机和主耳(右耳)建立(BR/EDR)ACL链路时，可以使用MAC地址2与手机建立ACL链路。主耳(右耳)在向手机上报主耳和副耳真实的MAC地址时，可以上报(MAC地址2，MAC地址1)，表示主耳(右耳)的真实MAC地址为MAC地址2，对耳(左耳)的真实MAC地址为MAC地址1。
示例性的，表1示出了右耳为主耳时，主耳在BR/EDR模式和BLE模式下的工作状态。

示例性的，若左耳位于用户的耳中，右耳不再用户的耳中，此时左耳为主耳。那么其实是主耳(左耳)可以通过MAC地址2和手机建立ACL链路，手机向主耳(左耳)询问是否支持双模。若主耳(左耳)返回的能力查询响应信息中指示支持双模，那么手机会接着向主耳(左耳)查询MAC地址信息。主耳(左耳)会向手机返回其真实的MAC地 址为MAC地址1，以及对耳(右耳)的MAC地址为MAC地址2。
应理解，手机和主耳(左耳)建立(BR/EDR)ACL链路时，可以使用MAC地址2与手机建立ACL链路。主耳(左耳)在向手机上报主耳和副耳真实的MAC地址时，可以上报(MAC地址1，MAC地址2)，表示主耳(左耳)的真实MAC地址为MAC地址1，对耳(右耳)的真实MAC地址为MAC地址2。
示例性的，表2示出了在左耳为主耳时，主耳在BR/EDR模式和BLE模式下的另一工作状态。
表2主耳在BR/EDR模式和BLE模式下的另一工作状态

示例性的，当右耳为主耳时，主耳(右耳)会向手机返回其真实的MAC地址为MAC地址2，以及对耳(左耳)的MAC地址为MAC地址1。那么手机其实是和主耳(右耳)真实的MAC地址(MAC地址2)建立BLE连接。手机和副耳(左耳)真实的MAC地址(MAC地址1)建立BLE连接。

S1002，响应于用户打开耳机盒的操作，蓝牙耳机的左耳和右耳建立BR/EDR连接。
S1003，主耳判断已配对设备清单(paired device list，PDL)PDL是否为空。
应理解，蓝牙耳机确定主耳和副耳的过程可以参考上述方法500中的描述，为了简洁，在此不再赘述。
例如，若PDL不为空，则主耳可以通过针对上一次连接的电子设备的MAC地址发起page。
又例如，若PDL为空，则蓝牙耳机为第一次开盒或者上次开盒没有连接其他电子设备。
S1004，蓝牙耳机检测到用户按压功能键的操作。

应理解，S1001-S1015是以手机主动搜索蓝牙耳机为例进行说明，该过程可以参考上述方法700中S701-S712的过程的描述。
还应理解，S1001-S1015还可以替换为上述方法500中S501-S506的过程，即手机可以通过主动搜索与主耳建立(BR/EDR)ACL链路，也可以是蓝牙耳机通过靠近发现与手机建立(BR/EDR)ACL链路。
S1016，手机的蓝牙协议栈(Bluetooth stack)向主耳发送能力查询请求信息，用于查询蓝牙耳机是否支持双模。
本申请实施例中，手机在和蓝牙耳机建立ACL链路后就可以向蓝牙耳机发送能力查询请求信息，这样不需要手机和蓝牙耳机建立好蓝牙连接就可以进行能力交互，在手机和蓝牙耳机都支持双模时，有助于节省手机和蓝牙耳机通过第二模式建立连接的时延。
S1017，主耳向手机发送能力查询响应信息，该能力查询响应信息用于指示蓝牙耳机支持双模。
示例性的，手机通过echo向主耳发送该能力查询请求信息，可以确认双方所支持的版本，确保实现版本兼容。
S1018，手机的蓝牙协议栈确定自己是否支持双模。
应理解，若手机和蓝牙耳机都支持双模，且主版本相同，则手机和蓝牙耳机可以则进 入第二模式连接。
应理解，S1018和S1016-S1017之间并没有实际的先后顺序。可以是手机先判断自己是否支持双模，在确定自己支持双模后，手机在执行S1016；可以是手机向执行S1016-S1017，在确定蓝牙耳机支持双模后，手机在判断自己是否支持双模。
若手机的蓝牙协议栈确定自己不支持双模，则执行S1019-S1021的步骤。
若手机的蓝牙协议栈确定自己也支持双模，则执行S1022以后的步骤。
S1019，手机的蓝牙协议栈和主耳之间进行(BR/EDR)配对/SDP/加密的过程。
S1020，手机的蓝牙协议栈向手机的settings上报连接事件。

示例性的，如图6中的(g)所示，在蓝牙设置界面中在已配对设备中可以显示设备名为“蓝牙耳机”的蓝牙设备和手机已连接。
S1022，手机的蓝牙协议栈向主耳发送MAC地址查询信息，该MAC地址查询信息用于查询主耳和副耳真实的MAC地址。
一个实施例中，手机的蓝牙协议栈可以通过(BR/EDR)L2CAP Echo携带自己的版本信息，确认双方可支持的第二模式协议版本。手机向耳机发起蓝牙地址查询请求，在回声请求echo request消息中携带手机的BR MAC地址和随机的BLE地址。蓝牙耳机在接收到手机的版本信息后，即可以确定手机希望查询主耳和副耳真实的MAC地址。
示例性的，手机携带的版本信息中可以包括1个字节用来指示主版本号，1个字节指示子版本号。
S1023，主耳向手机的蓝牙协议栈发送MAC地址查询响应信息，该MAC地址查询响应信息中携带主耳和副耳真实的MAC地址。
应理解，该S1023的过程可以参考上述方法900中的描述，为了简洁，在此不再赘述。
S1024，主耳向副耳发送(BR/EDR)同步配对信息，将BR/EDR下生成的链路密钥(link key)同步给副耳。
S1025，主耳通知副耳发送标准的BLE不可连接广播。
S1026，主耳停止发送不可连接广播。
S1027，主耳使用其真实的MAC地址发送可连接广播，从而手机可以向主耳发起BLE连接。
S1028，副耳使用其真实的MAC地址发送可连接广播，从而手机可以向副耳发起BLE连接。
蓝牙耳机可以先停止发送不可连续广播，在转为发送可连续广播。
S1029，手机的蓝牙协议栈将主耳和副耳真实的MAC地址加入白名单中。
S1030，手机的蓝牙协议栈通知蓝牙控制器断开与主耳之间的ACL链路。
S1031，手机的蓝牙控制器与主耳之间断开ACL链接。
示例性的，手机的蓝牙协议栈可以向主耳发送(BR/EDR)ACL链路断开事件，主耳可以向蓝牙协议栈返回(BR/EDR)ACL链路断开完成事件。
S1032，手机的蓝牙协议栈与主耳之间建立(BLE)ACL链路。
S1033，主耳停止发送可连接广播。
S1034，手机的蓝牙协议栈与主耳之间进行(BLE)加密/SDP过程。
S1035，手机的蓝牙协议栈与主耳之间建立(BLE)HFP/A2DP连接。
示例性的，当手机通过蓝牙耳机接听电话时，手机和主耳之间可以进行HFP连接。
示例性的，当手机通过蓝牙耳机听音乐，看视频时，手机和主耳之间可以进行A2DP连接。
S1036，手机的蓝牙控制器与副耳至今建立(BLE)ACL链路。
S1037，副耳停止发送可连续广播。
S1038，手机的蓝牙协议栈与副耳之间进行(BLE)加密/SDP过程。
S1039，手机的蓝牙协议栈与副耳之间建立(BLE)HFP/A2DP连接。
S1040，手机的蓝牙协议栈向settings上报连接事件。
S1041，手机的蓝牙设置界面显示手机和蓝牙耳机已连接。
示例性的，如图6中的(g)所示，在蓝牙设置界面中在已配对设备中可以显示设备名为“蓝牙耳机”的蓝牙设备和手机已连接。
本申请实施例中，当手机和蓝牙耳机都支持双模，或者说手机和蓝牙耳机都支持BR/EDR模式和BLE模式时，手机和蓝牙耳机可以从BR/EDR模式连接切换至BLE模式连接，这样有助于节省手机和蓝牙耳机的功耗。
