蓝牙设备可以通过相应的配置文件与其它设备进行通信。 例如, HFP (免提配置文件 )描述了网关设备如何用于供免提设备拨打和接听呼叫; A2DP (高级音频分发配置文件 )描述了立体声质量音频如何从媒体源流化 传送至蓝牙配件。
当蓝牙配件可以使用不同的配置文件同时连接到两个设备(例如蜂窝 电话和媒体播放器) 时, 用户可以在来电之前, 使用 A2DP收听从媒体播 放器播放的音乐; 在来电时, 该蓝牙配件可以自动中断音乐播放, 并且在 用户接听来电时, 蓝牙配件可以使用 HFP接收或传送语音信息。 在用户完 成通话后, 蓝牙配件可以使用 A2DP继续接收音乐。
蓝牙配件接收或传送各种信息的前提是必须与蓝牙设备进行配对并建 立连接。
现有的蓝牙配件与多个蓝牙设备配对所釆用的方法有: 对蓝牙配件的 配对设备列表进行检查, 以确定具有特定的蓝牙简档的最近配对的设备,
蓝牙简档例如免提简档 (HFP )或高级音频分发简档 (A2DP )。 如果找到, 则蓝牙配件尝试与配对设备连接。 否则, 蓝牙配件根据连接的先后继续尝 试与配对设备列表中的设备连接, 直到蓝牙配件有两个不同简档的连接为 止。 如果没有进行连接, 或者配对设备列表是空的, 则蓝牙设备进入可发 现模式。 其存在以下缺陷:
1、 现有的配对方法按照配置文件的不同, 优先搜索并连接最后连接过 的蓝牙设备。 而按照用户的使用习惯, 蓝牙配件连接次数最多的蓝牙设备, 是用户下一次最有可能使用的蓝牙设备; 当多个蓝牙设备与蓝牙配件配对 时, 其配对过程较为繁瑣, 用户体验效果不佳;
2、 蓝牙配件一加电, 就开始根据配对列表中配对情况进行搜索, 其搜 索时间长达 30s-60s, 直到搜索结束, 才进入可发现模式, 由此带来很大的 延迟, 而在这 30s-60s期间, 其它蓝牙设备无法主动连接到蓝牙配件。 发明内容

图 3是本发明蓝牙配件配对蓝牙设备的方法另一实施例流程示意图;
图 4是本发明配对蓝牙设备的蓝牙配件一实施例结构示意图; 图 5是本发明配对蓝牙设备的蓝牙配件另一实施例结构示意图。 具体实施方式
本发明实施例解决方案主要是: 以蓝牙设备与蓝牙配件连接数多少为 连接优先级, 蓝牙配件加电后, 根据连接优先级从配对列表中搜索预定个 数的蓝牙设备, 并与搜索出的蓝牙设备建立连接, 同时, 在蓝牙配件搜索 的过程中, 可根据用户的外部指令随时终止搜索, 进入可发现模式, 以便 与配对列表之外的其他设备进行配对和建立连接, 以提高配对的灵活性, 减少配对的延迟。
如图 1所示, 本发明一实施例提出一种蓝牙配件配对蓝牙设备的方法, 包括:
步骤 S101 , 在蓝牙配件加电后, 蓝牙配件查看存储在蓝牙设备中的配 对列表;
步骤 S102, 当配对列表不为空时, 蓝牙配件根据蓝牙设备的连接优先 级从配对列表中搜索预定个数的蓝牙设备, 并与搜索出的蓝牙设备建立连 接。
其中, 连接优先级基于蓝牙设备与蓝牙配件建立的相应配置文件的连 接次数设定, 连接次数越多, 连接优先级则越高。 连接次数是指蓝牙配件 与蓝牙设备建立相应配置文件类型的连接的次数。
配对列表存储于蓝牙设备的存储器中, 配对列表中保存的是与蓝牙配 件进行过连接操作的蓝牙设备的信息, 包括但不限于如下设备信息: 蓝牙 设备的类型、 蓝牙设备与蓝牙配件同时支持的配置文件以及蓝牙设备与蓝 牙配件建立的相应配置文件的连接次数。
如下表 1所示的配对列表中 , 蜂窝电话同时支持 HFP和 A2DP配置文 件,蓝牙配件与蜂窝电话已经建立了 50次 HFP连接和 8次 A2DP连接, 因
此蜂窝电话在配对列表中出现了两次。 蓝牙配件与 MP3和 CD播放器分别 建立过 A2DP连接,与设备 1建立过 DUN连接,与设备 2建立过 FTP连接。 蓝牙配件与何种设备建立过何种连接, 取决于蓝牙配件所支持的配置文件 类型。 这里规定, 蓝牙配件与蓝牙设备同时支持多个配置文件。
表 1
因为按照用户的使用习惯, 蓝牙配件连接次数最多的蓝牙设备, 是用 户下一次最有可能使用的蓝牙设备; 所以可以根据连接次数排出连接优先 级, 优先对连接次数最多的蓝牙设备发起连接操作。
蓝牙配件根据蓝牙设备的连接优先级从配对列表中搜索预定个数的蓝 牙设备, 并与搜索出的蓝牙设备建立连接的过程具体为: 蓝牙配件从配对 列表中搜索连接优先级最高的蓝牙设备, 若搜索到, 则与搜索出的蓝牙设 备建立相应配置文件的连接; 否则, 蓝牙配件从配对列表中搜索下一连接 优先级的蓝牙设备, 并与搜索出的蓝牙设备建立相应配置文件的连接; 直 至搜索到预定个数的蓝牙设备, 并与搜索出的蓝牙设备建立相应配置文件 的连接。
以上表 1为例, 蓝牙配件与蓝牙设备同时支持 HFP和 A2DP两种配置 文件, 蓝牙配件根据连接次数 "预测出" 用户将要连接的设备: 首先, 找
到连接次数最多的设备(如下表 1所示, 该设备为蜂窝电话), 并搜索该设 备, 如果搜索到该设备, 则根据设备的类型, 判断出与该设备建立何种类 型的连接, 例如, 对于蜂窝电话, 主要是用于通话, 尽管同时支持 HFP和 A2DP, 相比 A2DP, 蓝牙配件与蜂窝电话建立的 HFP连接较多, 蓝牙配件 优先建立 HFP连接。
在建立 HFP连接后, 蓝牙配件继续查找连接次数较多, 且支持其它配 置文件(例如 A2DP )的其它设备。 尽管蜂窝电话支持 A2DP, 但是由于蓝 牙配件已建立了 HFP连接, 故蜂窝电话不在搜索的范围之内。 蓝牙配件在 MP3、 CD播放器以及设备 1、 2等设备范围内进行查找, 寻找连接次数最 多的设备。
根据上述规则, 蓝牙配件与 MP3 建立连接的次数最多, 因此对 MP3 进行搜索, 如果搜索到该设备, 则蓝牙配件与该设备建立其它类型 (例如 A2DP ) 的连接。 需要说明的是, 如果 MP3 是蓝牙配件在第二次搜索中搜 索到的连接次数最多的设备,而该连接数的 MP3对应的配置文件为 A2DP, 由于 A2DP 已经由蜂窝电话建立过连接, 因此, 蓝牙配件不能与第二次搜 索中搜索到的连接次数最多的 MP3建立 A2DP连接, 而需要在下一级连接 次数最多的设备中进行搜索, 并以蓝牙设备类型及配置文件类型同时作为 判断是否连接的条件。
其中, 预定个数可以为蓝牙设备与蓝牙配件同时支持的配置文件的种 类数, 若蓝牙配件经过搜索已经建立了其所支持的所有配置文件的连接, 则配对连接过程结束。 比如在上表 1中, 配对列表中包含 HFP及 A2DP两 种类型的配置文件, 蓝牙配件与蓝牙设备均同时只支持该 HFP及 A2DP两 种类型的配置文件, 当蓝牙配件经过两次搜索, 分别与蜂窝电话及 MP3建 立了连接后, 配对连接过程则结束。
如图 2所示, 上述步骤 S102中蓝牙配件根据蓝牙设备的连接优先级从
配对列表中搜索预定个数的蓝牙设备, 并与搜索出的蓝牙设备建立连接的 步骤包括:
步骤 S1021 ,蓝牙配件从配对列表中搜索连接次数最多的蓝牙设备, 并 与该蓝牙设备建立相应配置文件的连接;
步骤 S1022, 从配对列表中搜索下一个连接数最多的蓝牙设备; 步骤 S1023 ,判断该下一个连接数最多的蓝牙设备是否与蓝牙配件建立 过连接, 同时判断该下一个连接数对应的配置文件是否建立过连接; 若是, 则返回步骤 S1022; 否则, 进入步骤 S1024;
步骤 S1024,蓝牙配件与该下一个连接数最多的蓝牙设备建立相应配置 文件的连接;
步骤 S1025 ,判断是否搜索到预定个数的蓝牙设备并建立了相应配置文 件的连接, 若是, 则进入步骤 S1026; 否则, 返回步骤 S1022, 直至搜索到 预定个数的蓝牙设备, 并与搜索出的蓝牙设备建立相应配置文件的连接。
步骤 S1026, 结束配对连接流程。
本实施例以蓝牙设备与蓝牙配件连接数多少为连接优先级, 蓝牙配件 加电后, 根据连接优先级从配对列表中搜索预定个数的蓝牙设备, 并与搜 索出的蓝牙设备建立连接, 可使蓝牙配件自动配对多个蓝牙设备, 提高了 配对的灵活性, 减少了配对的延迟。
如图 3 所示, 本发明另一实施例提出一种蓝牙配件配对蓝牙设备的方 法, 包括:
步骤 S201 , 在蓝牙配件加电后, 蓝牙配件查看存储在蓝牙设备中的配 对列表是否为空; 若是, 则进入步骤 204; 否则, 进入步骤 S202;
步骤 S202, 根据蓝牙设备的连接优先级从配对列表中搜索预定个数的 蓝牙设备, 并与搜索出的蓝牙设备建立相应配置文件的连接;
步骤 S203 ,判断是否搜索到预定个数的蓝牙设备并建立了连接; 若是,
则进入步骤 S207; 否则, 进入步骤 S204;
步骤 S204, 进入可发现模式;
步骤 S205 , 在可发现模式中, 监听来自配对列表之外的其他蓝牙设备 的查询信息;
步骤 S206 , 根据查询信息向其他蓝牙设备发送响应消息, 以指示与该 其他设备进行配对和建立连接。
步骤 S207 , 结束配对连接流程。
在本实施例中, 与上述实施例相比, 其区别在于, 如果蓝牙配件不能 与蓝牙设备建立连接(比如配对列表为空的情况), 或者蓝牙配件没有建立 预定个数的连接(比如配对列表中), 则蓝牙配件进入可发现模式, 可以被 其它蓝牙设备发现来用于后续的配对和连接。 在可发现模式中, 蓝牙配件 将监听来自其他蓝牙设备的查询信息, 并对其他蓝牙设备的查询信息作出 响应。 蓝牙配件对查询信息的响应指示其可用于与其他蓝牙设备进行配对 和连接。 以这种方式, 使用蓝牙配件的用户可以不必执行繁瑣的人工配对 过程就可以自动将蓝牙配件与多个蓝牙设备进行配对。
进一步的, 在本实施例中, 在蓝牙配件从配对列表中搜索蓝牙设备的 过程中, 当蓝牙配件接收到外部输入的终止搜索指令时, 蓝牙配件终止搜 索动作, 并进入可发现模式, 监听来自配对列表之外的其他蓝牙设备的查 询信息; 根据查询信息向其他蓝牙设备发送响应消息, 以便与该其他设备 进行配对和建立连接。
具体地, 比如, 在蓝牙配件进行搜索过程中, 用户可以执行预定的操 作 (例如短暂按键操作) 来终止搜索过程, 使其直接进入可发现模式。 这 样其他蓝牙设备可以即时连接蓝牙配件, 避免了过多的时延。
上述预定的操作根据具体的蓝牙配件而设定, 即不同的蓝牙配件, 由 于其设备特性不同, 故执行中断开机搜索操作的方式也不同, 下面针对不
同的蓝牙配件举例说明该预定的操作方式。
针对蓝牙配件是蓝牙立体声耳机, 用户可以执行(但不限于)如下操 作以中断蓝牙配件的开机搜索过程: 在蓝牙立体声耳机加电开机后, 用户 可以双击耳机开机键, 以执行中断搜索操作;
针对蓝牙配件是蓝牙适配器, 用户可以执行(但不限于)如下操作以 中断蓝牙配件的 开机搜索过程: 蓝牙适配器对应的配套软件中加入一个操 作菜单项, 选择该菜单项能够中断开机搜索操作。 在蓝牙适配器加电后, 选择该操作菜单项;
针对蓝牙配件是车载设备, 用户可以执行(但不限于)如下操作以中 断蓝牙配件的开机搜索过程: 车载设备加电开机后, 用户短按车载设备上 的指定按键, 以执行中断搜索操作;
针对蓝牙配件是扬声器***, 用户可以执行(但不限于)如下操作以 中断蓝牙配件的开机搜索过程: 蓝牙扬声器***加电开机后, 用户短按扬 声器***上的指定按键, 以执行中断搜索操作。
如图 4所示, 本发明一实施例提出一种配对蓝牙设备的蓝牙配件, 包 括: 配对列表查看模块 301及连接建立模块 302; 其中:
配对列表查看模块 301 , 用于在蓝牙配件加电后, 查看存储在蓝牙设备 中的配对列表;
连接建立模块 302, 用于当配对列表不为空时,根据蓝牙设备的连接优 先级从配对列表中搜索预定个数的蓝牙设备, 并与搜索出的蓝牙设备建立 连接。
其中, 连接优先级基于蓝牙设备与蓝牙配件建立的相应配置文件的连 接次数设定, 连接次数越多, 连接优先级则越高。 连接次数是指蓝牙配件 与蓝牙设备建立相应配置文件类型的连接次数。
配对列表存储于蓝牙设备的存储器中, 配对列表中保存的是与蓝牙配
件进行过连接操作的蓝牙设备的信息, 包括但不限于如下设备信息: 蓝牙 设备的类型、 蓝牙设备与蓝牙配件同时支持的配置文件以及蓝牙设备与蓝 牙配件建立的相应配置文件的连接次数。
如上表 1所示的配对列表中 , 蜂窝电话同时支持 HFP和 A2DP配置文 件,蓝牙配件与蜂窝电话已经建立了 50次 HFP连接和 8次 A2DP连接, 因 此蜂窝电话在配对列表中出现了两次。 蓝牙配件与 MP3和 CD播放器分别 建立过 A2DP连接,与设备 1建立过 DUN连接,与设备 2建立过 FTP连接。 蓝牙配件与何种设备建立过何种连接, 取决于蓝牙配件所支持的配置文件 类型。 这里规定, 蓝牙配件与蓝牙设备同时支持多个配置文件。
因为按照用户的使用习惯, 蓝牙配件连接次数最多的蓝牙设备, 是用 户下一次最有可能使用的蓝牙设备; 所以可以根据连接次数排出连接优先 级, 优先对连接次数最多的蓝牙设备发起连接操作。
蓝牙配件根据蓝牙设备的连接优先级从配对列表中搜索预定个数的蓝 牙设备, 并与搜索出的蓝牙设备建立连接的过程具体为: 蓝牙配件从配对 列表中搜索连接优先级最高的蓝牙设备, 若搜索到, 则与该蓝牙设备建立 相应配置文件的连接; 否则, 蓝牙配件从配对列表中搜索下一连接优先级 的蓝牙设备, 并与搜索出的蓝牙设备建立相应配置文件的连接; 直至搜索 到预定个数的蓝牙设备, 并与搜索出的蓝牙设备建立相应配置文件的连接。
以上表 1 为例, 蓝牙配件根据连接次数 "预测出" 用户将要连接的设 备: 首先, 找到连接次数最多的设备(如上表 1所示, 该设备为蜂窝电话), 并搜索该设备, 如果搜索到该设备, 则根据设备的类型, 判断出与该设备 建立何种类型的连接, 例如, 对于蜂窝电话, 主要是用于通话, 尽管同时 支持 HFP和 A2DP , 相比 A2DP , 蓝牙配件与蜂窝电话建立的 HFP连接较 多, 蓝牙配件优先建立 HFP连接。
在建立 HFP连接后, 蓝牙配件继续查找连接次数较多, 且支持其它配
置文件(例如 A2DP )的其它设备。 尽管蜂窝电话支持 A2DP, 但是由于蓝 牙配件已建立了 HFP连接, 故蜂窝电话不在搜索的范围之内。 蓝牙配件在 MP3、 CD播放器以及设备 1、 2等设备范围内进行查找, 寻找连接次数最 多的设备。
根据上述规则, 蓝牙配件与 MP3 建立连接的次数最多, 因此对 MP3 进行搜索, 如果搜索到该设备, 则蓝牙配件与该设备建立其它类型 (例如 A2DP ) 的连接。 需要说明的是, 如果 MP3 是蓝牙配件在第二次搜索中搜 索到的连接次数最多的设备,而该连接数的 MP3对应的配置文件为 A2DP, 由于 A2DP 已经由蜂窝电话建立过连接, 因此, 蓝牙配件不能与第二次搜 索中搜索到的连接次数最多的 MP3建立 A2DP连接, 而需要在下一级连接 次数最多的设备中进行搜索, 并以蓝牙设备类型及配置文件类型同时作为 判断是否连接的条件。
其中, 预定个数可以为蓝牙设备与蓝牙配件同时支持的配置文件的种 类数, 若蓝牙配件经过搜索已经建立了其所支持的所有配置文件的连接, 则配对连接过程结束。 比如在上表 1中, 配对列表中包含 HFP及 A2DP两 种类型的配置文件, 蓝牙配件与蓝牙设备均同时只支持该 HFP及 A2DP两 种类型的配置文件, 当蓝牙配件经过两次搜索, 分别与蜂窝电话及 MP3建 立了连接后, 配对连接过程则结束。
如图 5 所示, 本发明另一实施例提出一种配对蓝牙设备的蓝牙配件, 包括: 配对列表查看模块 401、 连接建立模块 402、 切换模块 403、 监听模 块 404以及响应模块 405; 其中:
配对列表查看模块 401 , 用于在蓝牙配件加电后, 查看存储在蓝牙设备 中的配对列表;

响应模块 405 , 用于根据查询信息向其他蓝牙设备发送响应消息, 以指 示连接建立模块 402与其他设备进行配对和建立连接;
上述连接建立模块 402,还用于根据响应消息的指示与其他设备进行配 对和建立连接。
进一步的, 切换模块 403还用于在连接建立模块 402从配对列表中搜 索蓝牙设备的过程中, 接收外部输入的终止搜索指令; 并根据所述终止搜 索指令, 进入可发现模式;
监听模块 404,还用于在切换模块 403接收到外部输入的终止搜索指令 时, 在可发现模式中, 监听来自配对列表之外的其他蓝牙设备的查询信息; 响应模块 405 ,还用于在切换模块 403接收到外部输入的终止搜索指令 时, 根据所述查询信息向所述其他蓝牙设备发送响应消息, 以指示连接建 立模块 402与其他设备进行配对和建立连接;
连接建立模块 402, 还用于根据终止搜索指令, 终搜索动作, 并根据所 述响应消息与其他设备进行配对和建立连接。
在本实施例中, 如果蓝牙配件不能与蓝牙设备建立连接(比如配对列 表为空的情况), 或者蓝牙配件没有建立预定个数的连接(比如配对列表 中), 则蓝牙配件进入可发现模式, 可以被其它蓝牙设备发现来用于后续的 配对和连接。 在可发现模式中, 蓝牙配件将监听来自其他蓝牙设备的查询 信息, 并对其他蓝牙设备的查询信息作出响应。 蓝牙配件对查询信息的响 应指示其可用于与其他蓝牙设备进行配对和连接。 以这种方式, 使用蓝牙
配件的用户可以不必执行繁瑣的人工配对过程就可以自动将蓝牙配件与多 个蓝牙设备进行配对。
进一步的, 在本实施例中, 在蓝牙配件从配对列表中搜索蓝牙设备的 过程中, 当蓝牙配件接收到外部输入的终止搜索指令时, 蓝牙配件终止搜 索动作, 并进入可发现模式, 监听来自配对列表之外的其他蓝牙设备的查 询信息; 根据查询信息向其他蓝牙设备发送响应消息, 以便与该其他设备 进行配对和建立连接。
具体地, 比如, 在蓝牙配件进行搜索过程中, 用户可以执行预定的操 作 (例如短暂按键操作) 来终止搜索过程, 使其直接进入可发现模式。 这 样其他蓝牙设备可以即时连接蓝牙配件, 避免了过多的时延。
上述预定的操作根据具体的蓝牙配件而设定, 即不同的蓝牙配件, 由 于其设备特性不同, 故执行中断开机搜索操作的方式也不同, 下面针对不 同的蓝牙配件举例说明该预定的操作方式。
针对蓝牙配件是蓝牙立体声耳机, 用户可以执行(但不限于)如下操 作以中断蓝牙配件的开机搜索过程: 在蓝牙立体声耳机加电开机后, 用户 可以双击耳机开机键, 以执行中断搜索操作;
