具体实施方式
本发明提供一种基于低功耗蓝牙和传统蓝牙的微微网组网互连方法及***，为使本发明的目的、技术方案及优点更加清楚、明确，以下参照附图并举实施例对本发明进一步详细说明。应当理解，此处所描述的具体实施例仅仅用以解释本发明，并不用于限定本发明。
首先对低功耗蓝牙协议进行详细说明，具体如下。
与传统蓝牙相比，低功耗蓝牙(Bluetooth Low Energy，BLE)的优点是省功耗，同时传输的数据量也比较小，适用于智能终端之间的组网过程。BLE协议的开发主要在链路层(Link Layer，LL)，通用访问协议层(Generic Access Profile，GAP)和通用属性协议层(Generic Attribute Profile，GATT)，下面将分别作介绍。
根据蓝牙联盟发布的低功耗蓝牙协议，链路层定义了BLE信道的信令，广播信道的角色和状态。BLE信道的信令格式如表1所示，适用于广播信 道和数据信道。其中，引导码Preamble和接入地址Access Address对于BLE信道来说是固定的数据，信令PDU(Protocol Data Unit，协议数据单元)可以在BLE信道中携带信息，CRC(Cyclic Redundancy Check，循环冗余校验码)用作循环校验。

表1
具体来说，广播信道的信令PDU由头Header和有效载荷Payload组成，如表2所示。
Figure PCTCN2016078634-appb-000006
表2
Header中的4比特PDU Type决定了广播信道的信令类型，如可连接非定向广播信令(ADV_IND)，可连接定向广播信令(ADV_DIRECT_IND)，不可连接非定向广播信令(ADV_NONCONN_IND)，扫描请求信令(SCAN_REQ)，扫描回复信令(SCAN_RSP)，连接请求信令(CONNECT_REQ)，可扫描非定向广播信令(ADV_SCAN_IND)，具体如表3所示。表3为广播信道的信令类型。

0001 ADV_DIRECT_IND
0010 ADV_NONCONN_IND
0011 SCAN_REQ
0100 SCAN_RSP
0101 CONNECT_REQ
0110 ADV_SCAN_IND
0111-1111 Reserved
表3
可连接非定向广播信令的Payload格式如表4所示。其中，AdvA表示 广播方的蓝牙地址，AdvData表示广播数据包，最多可携带31个字节的消息。
Figure PCTCN2016078634-appb-000007
表4
可连接非定向广播信令的广播数据包的格式如表5所示。其中，ADStructure表示消息段，一个广播数据包可容纳多个消息段；AD Type表示消息段的类型，如蓝牙名称，蓝牙制造商，UUID等；AD Data表示消息段的内容；Length(长度)的值表示Data的字节数。

表6
链路层在广播信道中定义了3种角色：非连接状态下的广播方(Advertiser)，扫描方(Scanner)和发起方(Initiator)。链路层在广播信道中定义了3种状态：广播状态，扫描状态和发起状态。
广播状态包括：
1)可连接非定向广播事件(Connectable undirected event)：广播方向周 围所有的扫描方广播ADV_IND信令，并声明自己处于可连接模式。广播方监听扫描方发来的SCAN_REQ信令，然后向扫描方发送SCAN_RSP信令。广播方也监听发起方发来的CONNECT_REQ信令；
2)可连接定向广播事件(Connectable directed event)：广播方向周围特定的扫描方广播ADV_DIRECT_IND信令，并声明自己处于可连接模式。广播方只监听特定发起方发来的CONNECT_REQ信令；
3)不可连接非定向广播事件(Non-connectable undirected event)：广播方向周围所有的扫描方广播ADV_NONCONN_IND信令，并声明自己处于不可连接模式。广播方不监听扫描方发来的信令；
4)可扫描非定向广播事件(Scannable undirected event)：广播方向周围所有的扫描方广播ADV_SCAN_IND信令。广播方只监听扫描方发来的SCAN_REQ信令，然后向扫描方发送SCAN_RSP信令。
扫描状态包括：
1)被动扫描：处于被动扫描模式的扫描方只能监听广播方广播的信令，不能对外发送数据；
2)主动扫描：处于主动扫描模式的扫描方监听广播方广播的信令，只对广播ADV_IND信令和ADV_SCAN_IND信令的广播方发送SCAN_REQ信令，发送完毕后继续监听广播方发来的SCAN_RSP信令。
发起状态包括：
1)处于发起状态的发起方可以对广播ADV_IND信令和ADV_DIRECT_IND信令的广播方发送CONNECT_REQ信令。
广播信道3种状态对应的信令关系如表7所示。

表7
GAP层定义了4种角色：广播角色(Broadcaster Role)、观察角色(Observer Role)、***角色(Peripheral Role)和中心角色(Central Role)。
广播角色：处于广播角色的设备以低功耗模式向周围广播，但不会响应其他设备发来的连接请求，即处于广播角色的设备处于不可连接模式。
观察角色：处于观察角色的设备可以扫描处于广播角色的设备，但不能发起连接请求，即处于观察角色的设备处于不可连接模式。
***角色：处于***角色的设备以低功耗模式向周围广播，响应其他设备发来的连接请求，即处于***角色的设备处于可连接模式。
中心角色：处于中心角色的设备可以扫描处于***角色的设备，可以发起连接请求，即处于中心角色的设备处于可连接模式。
LL层与GAP层的对应关系如表8所示。

表8中，“E”表示不支持，“M”表示必须支持，“O”表示选择支持，“O/E”表示如果中心角色支持被动扫描，那么中心角色选择支持主动扫描，否则中心角色必须支持主动扫描。本发明中定义中心设备(Central Device)和***设备(Peripheral Device)两种物理设备类型。中心设备：处于网络的中心位置，同时具有低功耗蓝牙和传统蓝牙功能；***设备：处于网络的***位置，同时具有低功耗蓝牙和传统蓝牙功能。
当***设备处于***角色，在低功耗模式下，以可连接非定向方式向周围广播ADV_IND信令时，中心设备通过被动扫描可获得***设备的蓝牙地址和广播数据包，如表9所示。表9为GAP层的可连接非定向广播与 被动扫描机制。

下面概述一下传统蓝牙协议。
传统蓝牙的优点是传输数据量较大，数据传输速率也较快，适用于智能终端之间的互连过程。传统蓝牙协议的开发主要在逻辑链路控制与适配协议(Logical Link Control and Adaptation Protocol，L2CAP)和通用访问协议层(Generic Access Profile，GAP)，下面将分别作介绍。
根据蓝牙联盟发布的传统蓝牙协议，逻辑链路控制与适配协议(Logical Link Control and Adaptation Protocol，L2CAP)定义了命令格式和数据格式。两个蓝牙设备在通信过程中需要交互一系列的命令，命令信道的通用信令格式如表10所示。

通用访问协议层定义了查询、可被发现、连接、可被连接和已连接等动作和状态。
查询与可被发现：蓝牙设备通过时分复用方式可以同时查询附近的蓝牙设备和被附近的蓝牙设备发现，即传统蓝牙设备可以同时担任查询设备(Inquiring device)和可被发现设备(Discoverable device)。查询设备通过查询获得可被发现设备的蓝牙地址。查询设备和可被发现设备可能已经与另外一个蓝牙设备处于连接状态，但仍保持查询和可被发现功能。
连接与可被连接：蓝牙设备通过时分复用方式可以同时连接附近的蓝牙设备和被附近的蓝牙设备连接，即蓝牙设备可以同时担任连接设备(Connecting device)和可被连接设备(Connectable device)。连接设备向可被连接设备发送连接请求(Connection Request)信令；可被连接设备向连接设备发送连接回复(Connection Response)信令，如表18所示。表18为可连接设备与可被连接设备之间的信令交互。连接成功后，发起连接的蓝牙设备在网络中成为主机(Master)，被连接的蓝牙设备在网络中成为从机(Slave)。
Figure PCTCN2016078634-appb-000014
表18
连接设备和可被连接设备可能已经与另外一个蓝牙设备处于连接状态，但仍保持连接和可被连接功能。
已连接状态：当两个蓝牙设备成功连接后，可以互相发送字符串消息。两个蓝牙设备在保持连接的同时，具有查询、可被发现、连接、可被连接的功能。
关于网络拓扑结构，多个蓝牙设备之间可以通过连接组成一个网络。譬如微微网(Piconet)，即以一蓝牙设备为主机，另一蓝牙设备为从机的Piconet，在Piconet中，主机可以同时向网络中的所有从机发送字符串消息，所有从机可以单独向主机发送字符串消息。
请参阅图1，图1为本发明提供的基于低功耗蓝牙和传统蓝牙的微微网组网互连方法较佳实施例的流程图，如图所示，所述方法包括以下步骤：
步骤S100、多个***设备以低功耗模式向周围以可连接非定向方式广播各自对应的多个无线连接是否支持的业务类型信息及多个无线连接对应的业务地址信息；中心设备扫描并获取各***设备对应的蓝牙地址、业务类型信息和业务地址信息；
步骤S200、中心设备根据各***设备对应的蓝牙地址、业务类型信息和业务地址信息，生成对应的***设备业务列表，以完成中心设备和多个***设备的组网；
步骤S300、组网完成后，中心设备根据业务请求建立中心设备和***设备的传统蓝牙连接，并组建对应的微微网，根据所述***设备业务列表使任意两个设备无线连接。
下面结合具体的实施例对上述步骤进行详细的描述。
在步骤S100中，多个***设备以低功耗模式向周围以可连接非定向方式广播各自对应的多个无线连接是否支持的业务类型信息及多个无线连接对应的业务地址信息；中心设备扫描并获取各***设备对应的蓝牙地址、业务类型信息和业务地址信息。具体来说，***设备和中心设备具体是指各种智能终端，如智能电视、无线音响、智能手机、平板、笔记本、电脑、无线路由器、无线相机、无线投影仪、智能灯具、智能冰箱、智能热水器及智能打印机等，这些智能终端一般都具备蓝牙功能。
具体来说，***设备以低功耗模式向周围以“可连接非定向”方式广播自己支持的无线连接业务类型和业务地址，如表19所示(中心设备和外 围设备都有该业务表)。
业务类型 是否支持 业务地址
0：WiFi 11111111 Add 0
1：NFC 00000000 Null
... ... ...
255：GNSS 11111111 Add 255
表19
中心设备被动扫描周围的***设备，得到所有***设备的蓝牙地址、支持的业务类型和业务地址，组成***设备业务列表，如表20所示，组网完成。
Figure PCTCN2016078634-appb-000015
表20
在实际应用时，可连接非定向广播信令修改点具体为：***设备在低功耗模式下，利用广播数据包向周围以“可连接非定向”方式周期性动态广播自己支持的业务类型和业务地址，自定义的广播数据包如表21所示。
Figure PCTCN2016078634-appb-000016
表21
其中，Length的值表示AD Type，Data中的Service Type，Service Support和Service Address的字节总数；AD Type的值为“22”，该值未被蓝牙联盟定义过，防止对其他BLE设备产生干扰，已经被蓝牙联盟定义的AD Type 字段如表6所示；Data中的Service Type表示业务类型，最多可表示256种业务；Service Support表示***设备是否支持该业务，用“11111111”表示支持，用“00000000”表示不支持；Service Address表示支持的业务地址，如果不支持该业务，则Service Address的值为“00000000”；剩下的广播数据包字节补零。
优选地，在实际应用时，周期性广播模式有两种可选。也就是说所述步骤S100有两种实现方式，其中，第一种实现方式，所述步骤S100具体包括：
S111、多个***设备在低功耗模式下，利用广播数据包向周围以可连接非定向方式周期性动态广播其全部的业务类型信息和业务地址信息；
S112、中心设备周期性扫描周围的***设备，扫描周期设置成与所有***设备的广播周期一致；
S113、中心设备经过一轮扫描后，获得所有***设备各自对应蓝牙地址、支持的业务类型信息和业务地址信息。
具体来说，***设备周期性广播全部256种业务类型和业务地址(不支持的业务类型的业务地址用“00000000”表示)，中心设备周期性扫描周围的***设备，扫描周期(Scanning period)设置成与所有***设备的广播周期(Advertising Period)一致，经过一轮256个扫描周期后，中心设备可以获得所有***设备蓝牙地址，支持的业务类型和业务地址，如表20所示，组网完成。
第二种实现方式，所述步骤S100具体包括：
S121、多个***设备在低功耗模式下，利用广播数据包向周围以可连接非定向方式周期性动态广播其支持的业务类型信息和业务地址信息；
S122、中心设备周期性扫描周围的***设备，设扫描周期为T，某***设备支持的业务种类数为x，则该***设备的广播周期为
Figure PCTCN2016078634-appb-000017
同时等 待时间为
Figure PCTCN2016078634-appb-000018
其中[log2 x]表示大于等于log2x的最小整数；
S123、中心设备经过一轮扫描后，获得所有***设备各自对应蓝牙地址、支持的业务类型信息和业务地址信息。
具体来说，***设备周期性广播支持的业务类型和业务地址，不广播不支持的业务类型和业务地址，中心设备周期性扫描周围的***设备，举例来说，绿色字体的***设备只支持1种业务类型，每隔256个扫描周期广播，红色字体的***设备支持256种业务类型，每隔1个扫描周期广播。
一般情况下，设扫描周期为T，***设备支持的业务种类为x，则***设备的广播周期为
Figure PCTCN2016078634-appb-000019
同时等待时间为
Figure PCTCN2016078634-appb-000020
其中[log2 x]表示大于等于log2x的最小整数。也就是说***设备的广播周期和等待时间根据支持的业务种类不同而不同，如表22所示。表22为***设备不同业务种类的广播周期与等待时间对应关系。
支持的业务种类 广播周期 等待时间
1 256T 0
2 128T 0
3 64T 64T
... ... ...
256 1T 0
表22
中心设备经过一轮256个扫描周期后，可以获得所有***设备蓝牙地址，支持的业务类型和业务地址的列表，如表20所示，组网完成。上述第一种实现方式和第二种实现方式各有优点，第一种实现方式统一设置广播方，较易实现；第二种实现方式根据广播方支持的业务种类，设置不同的广播周期，节省功耗。
在步骤S200中，中心设备根据各***设备对应的蓝牙地址、业务类型信息和业务地址信息，生成对应的***设备业务列表，以完成中心设备和多个***设备的组网。
在步骤S300中，组网完成后，中心设备根据业务请求建立中心设备和***设备的传统蓝牙连接，并组建对应的微微网，根据所述***设备业务列表使任意两个设备无线连接。具体来说，当中心设备和***设备组网完成后，中心设备得到***设备业务列表(表20)，中心设备和***设备在保持低功耗蓝牙功能的同时，也保持传统蓝牙的功能，并且依靠传统蓝牙完成互连过程。
只有当中心设备主动触发业务或收到***设备的业务触发请求时，中心设备和***设备才建立传统蓝牙连接，组成Piconet网络，通知无线连接的业务类型、业务地址和主从模式。互连过程可分为4个应用场景，以下将分别作介绍。
本发明基于低功耗蓝牙和传统蓝牙的微微网组网互连方法，任意两个设备便可通过对应的无线连接的业务类型、业务地址和主从模式，实现无线互联，譬如WIFI或NFC(Near Field Communication，近场通信)，从而进行无线连接业务，互连便利。假如甲设备想要与乙设备WIFI连接，只需将两设备通过中心设备组建对应的微微网，然后甲设备和乙设备通过传统蓝牙发送各自的蓝牙地址，根据WIFI业务类型和主从模式及对方的WIFI连接对应的WIFI业务地址，便可实现对应的WIFI连接。若甲设备和乙设备均为***设备，或者，也可以其中一个设备为中心设备。这样，给用户带来了大大的操作方便。操作简便、易于控制管理与触发智能终端之间的无线连接业务，同时智能终端要有较低的待机功耗。
在实际应用时，任意两个设备的互连可分为4个应用场景。以下分别进行详细说明如下。
请参阅图2，图2为本发明提供的基于低功耗蓝牙和传统蓝牙的微微网组网互连方法第一实施例的流程示意图。组网完成后，中心设备主动触发业务请求，分别向两个***设备发送业务类型和业务地址，两个***设备收到消息后实现互连。其中，***设备1即代表下文的第一***设备，外 围设备2代表下文的第二***设备。
进一步地，所述步骤S300具体包括：
S311、中心设备触发业务请求，通过传统蓝牙向第一***设备发送连接请求信令，第一***设备通过传统蓝牙向中心设备发送连接回复信令；中心设备与第一***设备建立连接，组成对应的微微网；
S312、中心设备以时分复用方式保持与第一***设备连接的同时，通过传统蓝牙向第二***设备发送连接请求信令，第二***设备通过传统蓝牙向中心设备发送连接回复信令；中心设备与第二***设备建立连接，将第二***设备加入到所述微微网中；
S313、中心设备通过所述微微网向第一***设备和第二***设备发送业务类型信息、业务地址信息和主从模式信息；
S314、第一***设备和第二***设备根据所述中心设备发送的业务类型信息、业务地址信息和主从模式信息直接对应进行无线互连。
具体来说，组网完成后，中心设备和***设备保持传统蓝牙的功能。当中心设备主动触发业务时，先向第一***设备(***设备1)发送“连接请求”信令，然后该***设备向中心设备发送“连接回复”信令。中心设备和第一***设备建立连接，组成Piconet，中心设备成为主机，***设备成为从机；然后，中心设备以时分复用方式保持与第一***设备连接的同时，向第二***设备(***设备2)发送“连接请求”信令，同样地，第二***设备向中心设备发送“连接回复”信令，中心设备与第二***设备建立连接。关于“连接请求”信令和“连接回复”信令，可参见传统蓝牙部分的描述。
在Piconet模式下，中心设备成为主机，两个***设备成为从机，中心设备可以同时向两个***设备发送字符串消息，包括业务类型、业务对象地址和主从模式数据。
在传统蓝牙L2CAP层中，将表17所示的Piconet主机发送数据包中的 Information Payload自定义成如表23所示。表23为自定义的Piconet数据包中的Information Payload格式。

其中，长度(Length)的值表示业务类型(Type)，业务对象地址(Object Address)和模式(Mode)的字节总数；模式用来选择执行无线连接业务的主机和从机，“11111111”表示主机，“00000000”表示从机。两个***设备收到中心设备发来的消息后，根据业务类型、业务对象地址和主从模式进行互连。
这样，中心设备通过组建相应的微微网，向微微网中的第一***设备和第二***设备发送业务类型信息和主从模式信息，将第一***设备对应的业务地址信息发送给第二***设备；将第二***设备对应的业务地址信息发送给第一***设备；使得第一***设备和第二***设备能够根据业务类型、业务对象地址和主从模式进行无线互连。
请参阅图3，图3为本发明提供的基于低功耗蓝牙和传统蓝牙的微微网组网互连方法第二实施例的流程示意图。***设备主动向中心设备触发业务请求，发送业务类型，中心设备收到消息后根据业务类型找到***设备业务列表中具有相同业务类型的另外一个***设备，然后中心设备分别向这两个***设备发送业务类型和业务地址，使得两个***设备收到消息后实现互连。其中，***设备1即代表下文的第一***设备，***设备2代表下文的第二***设备。
进一步地，所述步骤S300具体包括：
S321、当第一***设备主动向中心设备触发业务请求时，第一***设备通过传统蓝牙向中心设备发送连接请求信令，中心设备向第一***设备 发送连接回复信令，中心设备和第一***设备建立连接；
S322、第一***设备发送对应的业务类型信息至中心设备；
S322、中心设备根据所述***设备业务列表中查找支持与所述第一***设备的业务类型信息相同业务类型信息的第二***设备；
S323、中心设备通过传统蓝牙向第二***设备发送连接请求信令，第二***设备向中心设备发送连接回复信令，中心设备和第二***设备建立连接，组成对应的微微网；
S324、中心设备通过所述微微网向第一***设备和第二***设备发送业务类型信息、业务地址信息和主从模式信息；第一***设备和第二***设备根据所述中心设备发送的业务类型信息、业务地址信息和主从模式信息直接对应进行无线互连。
组网完成后，中心设备和***设备保持传统蓝牙的功能。当***设备有业务触发请求时，先向中心设备发送“连接请求”信令，中心设备向该***设备发送“连接回复”信令。当中心设备和***设备连接成功后，***设备发送业务类型字符串消息，将表16所示的Piconet从机发送数据包中的Information Payload自定义成如表23所示，其中，Object Address和Mode都无需设置，用“00000000”表示。
当中心设备收到上述消息后，根据业务类型找到***设备业务列表中支持相同业务类型的另外一个***设备(如存在多个支持相同业务类型的***设备，那么选择列表中符合条件的第一个***设备)，然后向该***设备发送“连接请求”信令，***设备向中心设备发送“连接回复”信令。
至此，中心设备和两个***设备组成Piconet，其中，中心设备成为主机，两个***设备成为从机，中心设备可以同时向两个***设备发送字符串消息，包括业务类型、业务对象地址和主从模式数据。
中心设备向两个***设备发送如表23所示的字符串消息，两个***设备收到中心设备发来的消息后，根据业务类型、业务对象地址和主从模式 进行互连。两个***设备收到中心设备发来的信令后，根据业务类型、业务对象地址和主从模式进行无线互连，进行无线连接业务，譬如WIFI或NFC。
