图6为本发明实施例公开的一种终端的结构示意图。
具体实施方式
如图1所示，路由器作为AP，提供Wi-Fi网络，Wi-Fi网络的覆盖范围的半径为X。第一终端在Wi-Fi网络的覆盖范围内，因此，可以接入该Wi-Fi网络。但是，第二终端和第三终端均不在该Wi-Fi网络的覆盖范围内,也就无法通过路由器接入该Wi-Fi网络。图1中所示的终端和路由器均遵循802.11协议。
本申请实施例公开的技术方案的目的在于，第一终端传递Wi-Fi信号，使得不在Wi-Fi网络的覆盖范围内的第二终端，通过第一终端的蓝牙个人局域网接入该Wi-Fi网络，进一步的，不在Wi-Fi网络的覆盖范围内的第三终端通过蓝牙功能与第二终端协商网络接入方式，在第二终端的蓝牙个人局域网被占用的情况下，第三终端将第二终端作为Wi-Fi热点接入该Wi-Fi网络。
图2为图1所示的终端1向终端2共享网络的具体过程，包括以下步骤：
S201：第一终端获取Wi-Fi网络的信息。
具体的，Wi-Fi网络的信息包括但不限于：Wi-Fi网络的名称、Wi-Fi网络的物理地址和Wi-Fi网络的信号强度。
具体的，S201中所述的“Wi-Fi网络”是指，第一终端搜索到的或者已连接的Wi-Fi网络。
S202：第一终端将Wi-Fi网络的信息发给第二终端。
可选的，S202的具体实现过程可以包括S2021-S2025：
S2021：第一终端将Wi-Fi网络的信息封装成浏览结果Scan Result数据。
Scan Result数据的数据结构为：
Figure PCTCN2017082392-appb-000001
其中，SSID表示Wi-Fi网络的名称，BSSID表示Wi-Fi网络的物理地址，level表示第一终端检测到的Wi-Fi网络的信号强度，level为可选参数。String表示字符串类型，int表示整型。
S2022：第一终端使用蓝牙广播第一消息，第一消息中包括Wi-Fi网络的信息。
除了Wi-Fi网络的信息之外，可选的，第一消息中还可以包括但不限于：第一终端接入Wi-Fi网络的方式，接入Wi-Fi网络的方式具体为Wi-Fi或蓝牙。
具体的，如表1所示，消息的数据结构为：
表1
Figure PCTCN2017082392-appb-000002
其中，UUID为标志符，标志该消息携带Wi-Fi网络的信息。Special_ID1和Access Method为键-值key-value对，Special_ID1表示第一终端接入Wi-Fi网络的方式，Access Method表示Special_ID1的值，即第一终端接入Wi-Fi网络的具体方式，Special_ID1具体为Wi-Fi或蓝牙。Special_ID2和Scan Result为key-value对，Special_ID2表示Wi-Fi网络的信息，Scan Result为Special_ID2的值，包括终端广播的Wi-Fi网络的信息的具体内容，Scan Result的具体数据结构如前述。
举例说明，本实施例中，第一终端通过蓝牙广播的消息为：UUID，Special_ID1，Wi-Fi，Special_ID2，{String SSID；String BSSID；int level；}。
第一终端可以使用低功耗的蓝牙BLE广播携带Wi-Fi网络的信息的消息，具体的，可以调用BLE接口start Advertising广播消息。BLE周期间隔地广播消息，同时可以接受来自其它设备的连接请求(低功耗蓝牙的连接是即时短暂的，只用于交换即时数据)。并且低功耗蓝牙的传输距离更长，可达100m。所以低功耗蓝牙可以用于消息广播、设备发现以及即时消息传输。除了蓝牙方式之外，第一终端也可以使用其它近距离通信手段向第二终端发送Wi-Fi网络的信息。
需要说明的是，第一终端使用蓝牙广播消息，需要先开启蓝牙，本实施例中，第一终端可以在S201或S202之前开启蓝牙，也可以在S201或S2021之后开启蓝牙，并不做限定。
S2023：第二终端扫描蓝牙信号，如果扫描到第一终端发出的蓝牙信号，则与第一终端建立蓝牙连接。
可选的，如果第一终端使用其它近距离通信手段例如近场通信(Near Field Communication，NFC)等向第二终端发送Wi-Fi网络的信息，则第二终端使用相应的方式接收。
可选的，第二终端扫描蓝牙信号由搜索Wi-Fi网络的指令触发，例如，用户在第二终端上的操作生成搜索Wi-Fi网络的指令，第二终端依据该指令开始扫描蓝牙信号。或者，第二终端周期性地自动扫描蓝牙信号。
S2024：第二终端接收第一终端通过蓝牙广播的第一消息。
S2025：第二终端通过解析第一消息，得到Wi-Fi网络的信息。
举例说明，第二终端接收到的第一消息为：UUID，Special_ID1，Wi-Fi，Special_ID2，{String SSID；String BSSID；int level；}，解析出UUID，则确认接收到Wi-Fi网络的信息，依据Special_ID1，Wi-Fi获得第一终端接入Wi-Fi网络的方式，依据Special_ID2，{String SSID；String BSSID；int level；}获得Wi-Fi网络的名称、 物理地址和信号强度。
至此，第二终端接收到第一终端发送的Wi-Fi网络的信息。
S203：第二终端显示Wi-Fi网络的信息。
具体的，第二终端将Wi-Fi网络的信息显示在本地Wi-Fi网络列表中，可选的，具体实现方式包括S2031-S2032：
S2031：第二终端结合蓝牙的信号强度和Wi-Fi网络的信号强度，计算相对信号强度。
计算相对信号强度的方法包括但不限于：将蓝牙信号的强度与Wi-Fi网络的信号强度相乘，得到相对信号强度。相对信号强度为即为Scan Result数据中的参数level。
S2032：第二终端将解析出的Wi-Fi网络的信息显示到本地的Wi-Fi网络列表中，可选的，显示相对信号强度。
图3为第一终端和第二终端上显示的Wi-Fi网络的列表，其中，第一终端上显示搜索到家庭路由器创建的名称为“123”的Wi-Fi网络，在执行上述步骤：第一终端通过蓝牙广播Wi-Fi网络的信息，第二终端接收到Wi-Fi网络的信息后，显示在Wi-Fi列表中后，第二终端上也显示名称为“123”的Wi-Fi网络。
第二终端在搜索到Wi-Fi网络后，用户可在第二终端上选择连接Wi-Fi网络，以图4为例，用户可以从Wi-Fi网络的列表中选择Wi-Fi网络“123”进行连接，从而触发第二终端通过蓝牙技术连接到Wi-Fi网络的过程。
需要说明的是，S203为可选步骤，也就是说，第二终端也可以不显示接收到的Wi-Fi网络的信息，而直接自动发起通过蓝牙技术连接到接收到的Wi-Fi网络的过程。
以下将对第二终端通过蓝牙连接到Wi-Fi网络的过程进行说明。
S204：第二终端向第一终端发送共享Wi-Fi网络的请求。
可选的，如果S2022接收到的第一消息中包括Special_ID1和Access Method键-值对，且Access Method为Wi-Fi，则说明第一终端通过Wi-Fi方式接入Wi-Fi网络，所以，第二终端向第一终端请求以蓝牙方式接入Wi-Fi网络。
可选的，第二终端也可以不进行上述判定，而直接向第一终端请求以蓝牙方式接入Wi-Fi网络。
或者，可选的，第二终端仅向第一终端请求共享Wi-Fi网络，而不规定以蓝牙或者Wi-Fi方式共享。
可选的，S204的具体实现方式为：第二终端向第一终端发送第一请求消息，第一请求消息中携带请求码，请求码的功能为第二终端是否具有通过蓝牙共享网络的权限。所述请求码预先设置，可以由用户自定义，例如，请求码可以为符号和/或数值的组合。
S205：第一终端开启蓝牙个人局域网(Bluetooth personal area networking)，并与第二终端建立蓝牙连接。
蓝牙个人局域网是一种通过蓝牙方式共享网络的技术。在开启蓝牙个人局域网后，实质上，第二终端的链路层转接到第二终端的蓝牙模块上，通过蓝牙模块接收的数据，可以通过链路层转发到Wi-Fi网络中，从Wi-Fi网络接收到的数据，也可以通过蓝牙 模块转发出去。
S205的具体实现方式可以为：第一终端通过开启本机的“蓝牙网络共享”开关，开启蓝牙个人局域网。第二终端开启蓝牙和第一终端配对(如前所述，如果第二终端与第一终端已经使用蓝牙发送过消息，则说明已经进行过蓝牙配对，则这里跳过蓝牙配对的步骤，如果第一终端与第二终端没有建立蓝牙连接，则需要进行配对)，并且开启与第一终端之间的蓝牙网络的“访问网络”开关，即与第二终端建立蓝牙连接。
可选的，第一终端在验证请求码合法的情况下，开启蓝牙个人局域网功能，并与第二终端建立蓝牙连接(如果之前第一终端与第二终端已经建立了蓝牙连接，则不再执行建立蓝牙连接的步骤)，如果验证请求码不合法，第一终端向第二终端发送第一响应消息，第一响应消息用于指示拒绝第二终端的请求。
S206：第二终端通过与第一终端的蓝牙连接，接入Wi-Fi网络。
需要说明的是，如果第一终端在S206之前，还没有接入Wi-Fi网络，则在S206第二终端建立蓝牙连接之前，第一终端要先接入Wi-Fi网络。
从图2可以看出，虽然第二终端不在Wi-Fi网络的覆盖范围内，但是通过第一终端的蓝牙个人局域网接入该Wi-Fi网络。相当于扩大了Wi-Fi网络的覆盖范围。
这种通过蓝牙共享网络的方式，仅利用终端的蓝牙功能即可实现，与现有的提高热点的发送功率的方式相比，能够节省功率，且具有较低的辐射。与现有的通过改进Wi-Fi芯片以使用Wi-Fi芯片作为中继的方式相比，因为不用升级硬件，所以具有较好的可实施性和较低的成本。
图4为本申请实施例公开的又一种网络共享方法，与图2相比，区别在于：第一终端在开启蓝牙个人局域网(Bluetooth personal area networking)功能之前，对第二终端进行蓝牙鉴权和/或Wi-Fi密码的验证。
蓝牙鉴权的具体实现方式如S405-S2042：
S405：第二终端使用基于通用属性配置文件(Generic Attribute Profile gatt)的蓝牙方式向第一终端发送第二请求消息，第二请求消息携带鉴权请求码，以请求第一终端进行蓝牙鉴权。
鉴权请求码的作用为请求进行蓝牙鉴权。鉴权码预先设置，可以由用户自定义。例如，鉴权码可以为符号和/或数值的组合。
通用属性配置文件(Generic Attribute Profile gatt)是一种低功耗的蓝牙协议。
S406：如果蓝牙鉴权成功，第一终端向第二终端发送第二响应消息，第二响应消息携带蓝牙鉴权成功码，否则，第一终端向第二终端发送拒绝连接的消息。
成功码的作用为指示蓝牙鉴权成功，成功码预先设置，可以由用户自定义，例如，成功码可以为符号和/或数值的组合。
蓝牙鉴权的目的在于，第一终端确认第二终端具有使用蓝牙与其连接的权限，以提高通信的安全性。S405-S406仅为终端之间进行蓝牙功能鉴权的一种实现方式，第二 终端和第一终端也可以使用其它方式进行蓝牙功能鉴权。
Wi-Fi密码的验证过程如S407-S408：
S407：第二终端显示输入Wi-Fi网络的密码的提示框，在接收到Wi-Fi网络的密码后，通过蓝牙向第一终端发送密码。
具体的，第二终端可以使用基于通用属性配置文件(Generic Attribute Profile gatt)的蓝牙方式向第一终端发送密码。
Wi-Fi网络的密码可以由用户在提示框中输入。
S408：第一终端通过将接收到的密码与本地存储的密码相比较，验证Wi-Fi网络的密码是否正确，如果正确，第一终端开启蓝牙个人局域网(bluetooth personal area networking)功能，并与第二终端建立蓝牙连接(如果之前第一终端与第二终端已经建立了蓝牙连接，则不再执行建立蓝牙连接的步骤)，否则，向第二终端发送拒绝接入网络的消息。
拒绝接入网络的消息可以为提示Wi-Fi网络的密码错误的消息。
如果Wi-Fi网络无需密码，则可跳过S407和S408。
或者，第二终端可以向第一终端发送账号信息，如果第二终端的账号信息与第一终端的账号信息相同(例如第一终端与第二终端登陆了相同的社交账号)，则也可以跳过S407和S408。
或者，第二终端可以向第一终端发送SIM卡信息，如果第二终端的SIM卡与第一终端的SIM卡相关联(例如，为主卡和副卡的关系)，则也可以跳过S407和S408。图4中的其它步骤均与图3相同，这里不再赘述。
图1所示的第二终端在接入Wi-Fi网络后，第三终端可以通过第二终端的共享，接入该Wi-Fi网络，图5为本申请实施例公开的又一种网络共享方法，与图2或图4所示的方法相比，主要区别为：因为第二终端使用蓝牙个人局域网接入Wi-Fi网络，所以，第二终端的蓝牙个人局域网功能被占用，而无法再使用蓝牙个人局域网向第三终端共享Wi-Fi网络，因此，第二终端作为热点与第三终端共享Wi-Fi网络。
图5包括以下步骤：
S501：第二终端获取Wi-Fi网络的信息。
S502：第二终端将Wi-Fi网络的信息发给第三终端。
与图2以及图4不同的是，第二终端发给第三终端的消息中如果包括Special_ID1和Access Method键-值对，则Method为蓝牙。
S503：第三终端显示Wi-Fi网络的信息。
S504：第三终端向第二终端发送共享Wi-Fi网络的请求。
可选的，如果S502接收到Special_ID1和Access Method键-值对，且Access Method为蓝牙，则说明第二终端通过蓝牙方式接入Wi-Fi网络，所以，第三终端向第二终端请求以Wi-Fi热点方式接入Wi-Fi网络。
可选的，第三终端也可以不进行上述判定，而直接向第二终端请求以Wi-Fi热点 方式接入Wi-Fi网络。或者，第三终端仅向第二终端请求共享Wi-Fi网络，而不规定以何种方式(蓝牙或者Wi-Fi方式)共享。
S505：第二终端开启Wi-Fi热点功能。
可选的，如果第三终端没有规定第二终端以何种方式共享Wi-Fi网络，则第二终端可以先判断本机的蓝牙个人局域网功能是否被占用，如果是，第二终端开启Wi-Fi热点功能。
S506：第三终端将第二终端作为Wi-Fi热点连接，以接入Wi-Fi网络。
从图3可以看出，在第二终端通过蓝牙个人局域网接入不在覆盖范围内的Wi-Fi网络后，第二终端还可以通过本机的Wi-Fi热点功能，将本机作为第三终端接入该Wi-Fi网络的热点。
如图1所示，Wi-Fi网络的覆盖范围的半径为X，蓝牙的广播范围为Y，则通过第一终端的广播，Wi-Fi网络的覆盖范围的半径可以扩展到X+Y。从理论上看，通过各个终端的蓝牙功能，可以实现Wi-Fi网络的覆盖范围的无限扩展，而实际上，可以考虑信号的衰减控制扩展范围，达到用户体验和扩展范围的平衡。
结合图2和图5可以看出，对于任意一个终端，使用蓝牙广播搜索Wi-Fi网络的方式相同。而接入Wi-Fi网络的方式，需要考虑该终端是否已使用蓝牙个人局域网入Wi-Fi网络，如果是，则因为蓝牙共享网络被占用，所以需要通过Wi-Fi热点共享网络，如果否，可以使用蓝牙个人局域网共享网络。
图6为本申请实施例公开的一种终端，包括：收发器和处理器，其中，收发器包括蓝牙组件和Wi-Fi组件。蓝牙组件用于实现图2、图4以及图5中通过蓝牙发送和接收的步骤以及蓝牙个人局域网的功能，Wi-Fi组件用于实现通过路由器Wi-Fi热点接入Wi-Fi网络以及为其它终端提供Wi-Fi热点的功能。处理器用于实现图2、图4以及图5中除通信组件的功能之外的步骤，以及，控制蓝牙组件和Wi-Fi组件分别实现蓝牙组件和Wi-Fi组件的上述功能。也就是说，图6所示的终端，可以为第一终端或者第二终端，也可以为集合了第一终端和第二终端的功能的终端。

所述处理器可以由集成电路(Integrated Circuit，IC)组成，例如可以由单颗封装的IC所组成，也可以由连接多颗相同功能或不同功能的封装IC而组成。举例来说，处理器可以仅包括中央处理器(Central Processing Unit，简称CPU)，也可以是GPU、数字信号处理器(Digital Signal Processor，简称DSP)、及通信单元中的控制芯片(例如基带芯片)的组合。在本发明实施方式中，CPU可以是单运算核心，也可以包括多运算核心。
存储器可用于存储软件程序以及模块，处理器通过运行存储在存储单元的软件程序以及模块，执行图2、图4以及图5中除通信组件的功能之外的步骤。存储器主要包括程序存储区和数据存储区，其中，程序存储区可存储操作系统、至少一个功能所需的应用程序等。数据存储区可存储根据在程序运行过程中产生的数据等。在本发明具体实施方式中，存储单元可以包括易失性存储器，例如非挥发性动态随机存取内存(Nonvolatile Random Access Memory，NVRAM)、相变化随机存取内存(Phase Change RAM，PRAM)、磁阻式随机存取内存(Magetoresistive RAM，MRAM)等，还可以包括非易失性存储器，例如至少一个磁盘存储器件、电子可擦除可编程只读存储器(Electrically ErasaBLE ProgrammaBLE Read-Only Memory，EEPROM)、闪存器件，例如反或闪存(NOR flash memory)或是反及闪存(NAND flash memory)。
可选的，终端还可以包括其他输入设备、传感器、显示屏和I/O子系统。I/O子系统包括其它输入设备的控制器、传感器控制器和显示控制器。
需要说明的是，上述实施例仅以Wi-Fi网络为例进行说明，除了Wi-Fi网络之外，其它的无线接入网络，例如蓝牙网络，也可以使用上述方法进行共享。
