背景技术
短距离无线通信指的是较短的距离内的通信，主要技术包括WIFI、紫蜂(Zigbee)、蓝牙技术(Bluetooth)、超宽带技术(UWB)、射频识别技术(RFID)以及近场通信(NFC)等类型。
目前在很多业务场景下需要设备与设备间建立短距离无线通道，例如，在某些业务场景下两台设备需要建立WIFI连接或蓝牙连接等。为了保障安全性，在初次建立短距离无线通道时，每种短距离无线通道均需要用户手工设置才可建立连接，因此设备间建立短距离无线通道的效率低，耗时长，特别是在需要建立多种短距离无线通道的业务场景下，效率低下的问题更为严重。
发明内容

根据本申请实施例的第一方面，提供一种建立短距离无线通道的方法，包括步骤：
从已建立的连接通道接收至少一条无线通道连接信息，所述无线通道连接信息中包括第二设备上的连接点标识；

具体实施方式
这里将详细地对示例性实施例进行说明，其示例表示在附图中。下面的描述涉及附图时，除非另有表示，不同附图中的相同数字表示相同或相似的要素。以下示例性实施例中所描述的实施方式并不代表与本申请相一致的所有实施方式。相反，它们仅是与如所附权利要求书中所详述的、本申请的一些方面相一致的装置和方法的例子。
在本申请使用的术语是仅仅出于描述特定实施例的目的，而非旨在限制本申请。在本申请和所附权利要求书中所使用的单数形式的“一种”、“所述”和“该”也旨在包括多数形式，除非上下文清楚地表示其他含义。还应当理解，本文中使用的术语“和/或”是指并包含一个或多个相关联的列出项目的任何或所有可能组合。
应当理解，尽管在本申请可能采用术语第一、第二、第三等来描述各种信息，但这些信息不应限于这些术语。这些术语仅用来将同一类型的信息彼此区分开。例如，在不脱离本申请范围的情况下，第一信息也可以被称为第二信息，类似地，第二信息也可以被称为第一信息。取决于语境，如在此所使用的词语“如果”可以被解释成为“在……时”或“当……时”或“响应于确定”。
很多业务场景中需要在两台设备之间建立不止一种连接通道，如图1所示，网络100中包括第一设备101、第二设备102，第一设备101和第二设备102可以具有建立不止一种连接通道(例如图中有线通道a、无线移动通道b、短距离无线通道c)的能力。有线通道a可以是USB通道等，无线移动通道b可以是GSM、3G、4G通道等。短距离无线通道c可以是WIFI通道、蓝牙通道、红外通道、NFC通道、RFID通道等。第一设备101和第二设备102可以是多种智能设备，例如，手机、平板电脑、电脑、智能耳机、智能电视、智能手表、汽车中的车机等。
在另一些业务场景中，网络100还可以包括服务器(图中未示出)，第一设备101和第二设备102分别具有与服务器103建立无线移动通道b的能力。
以下描述中第一设备101作为建立短距离无线通道的请求连接的设备，第二设备102作为被连接设备，值得指出，一个设备在某些场景下可以仅仅具备第一设备101或第二设备102的功能，在另一些场景下，可以同时具备第一设备101和第二设备102的功能。当两设备间建立短距离无线通道时，第一设备101根据第二设备102发布的连接点标识与第二设备102连接。在建立不同的短距离无线通道时，连接点标识可以不同，例如，在建立WIFI通道时，连接点标识可以是第二设备102发布的SSID(Service Set Identifier，服务集标识)；在建立蓝牙通道时，无线连接点标识可以是第二设备102发布的本设备的MAC地址；其他短距离无线通道的连接点标识不依次列举。
本申请提供设备间建立短距离无线通道的方法，可以提高建立短距离无线通道的效率。
图2从第一设备101侧描述其工作原理。
S201，从已建立的连接通道接收至少一条无线通道连接信息，该无线通道连接信息 中包括第二设备102上的连接点标识，连接点标识用来标识其中一条短距离无线通道的连接点。
S202，如果搜索到与所接收到的连接点标识相匹配的连接点，则根据所收到的无线通道连接信息与该连接点建立短距离无线通道。
可见，由于本申请无需人工选择连接点或手工输入密码，因此可以做到快速建立短距离无线通道。
除图2所示的步骤，在某些对安全性有一定要求的场合中，本申请可以通过身份验证来保证安全性，在建立短距离无线通道前，可以验证建立短距离无线通道所涉及到的设备的合法性。如果身份验证通过，则第一设备101可以自动获取无线通道连接信息；如果身份验证失败，则第一设备101仍需要通过用户人工选择连接点以及输入连接密码的方式与第二设备102建立短距离无线通道。
对待验证的设备合法性验证的方式可以是检查待验证的设备的账户是否为已登记的合法账户；或两端设备是否同属于同一账户名下或关联账户名下；或服务器上所记录的允许第一设备101连接的连接点列表是否为空等。
根据不同业务场景的需求，可以对第一设备101和第二设备102的其中之一是否为合法用户进行验证，也可以对两台设备均进行合法性验证。因此作为一个例子，当第一设备101需要被验证身份时，第一设备101可以将自身的身份验证标识通过已建立的连接通道发给负责身份验证的设备进行身份验证。
在一个实例中，图2中所揭示的方案应用于两设备间首次建立某种短距离无线通道的情况下，当建立成功后，可以将该短距离无线通道所对应的无线连接信息保存。因此，无论是首次还是再次建立短距离无线连接通道，可以首先查找是否已存储有相应的无线通道连接信息，如果没有，则将自身的身份验证标识通过已建立的连接通道发给所述被连接设备或所述服务器进行身份验证；如果找到所存储的无线通道连接信息，便可以根据所存储的无线连接信息实现自动连接。当根据所存储的无线通道连接信息与第二设备102未连接成功时，则删除所保存的无线通道连接信息。
由此看出，当第一设备101被更换、系统重启、账户密码更换等多种可能导致所存储的无线通道连接信息被清空的场景下，本申请可以方便的实现多种短距离无线通道的自动连接。
一个实施例中，可以由无线通道连接信息的发送方作为负责身份验证的设备。例如，如果第一设备101向服务器请求无线通道连接信息，则由服务器对第一设备101的身份 进行认证；再例如，如果第一设备101向第二设备102请求无线通道连接信息，则由第二设备102对第一设备101进行身份认证。服务器在实体上可以集成于第一设备101或第二设备102上，也可以独立于第二设备101和第二设备102。
在步骤S201中，第一设备101通过已建立的连接通道来获取到无线通道连接信息。以下对已建立的连接通道传输无线通道连接信息的情况进行举例说明。已建立的连接通道可以包括至少一种以下通道：有线通道a、无线移动通道b、短距离无线通道c。
S201a、通过已建立的无线移动通道b来接收无线通道连接信息。
作为一个实施例，可以由服务器利用无线移动通道b完成下发无线通道连接信息的功能。
在服务器上记录无线通道连接信息的方式可以是事先配置好，也可以是由第二设备102在某个时刻上传给服务器(例如，可以是第二设备102在登录服务器时，将无线通道连接信息上传给服务器)。
服务器上所记录的无线通道连接点的信息可以只包括其中一种短距离无线通道建立时所需要的信息，也可以包括两种或以上短距离无线通道在建立时所需要的信息。例如，服务器上记录的无线通道连接信息可以是与第二设备102建立WIFI通道所用到的SSID及WIFI密码；也可以是第二设备102的MAC地址及蓝牙密码；再或者，可以两种均记录。对于其他无线通道连接信息不依次举例说明。
服务器下发无线通道连接信息给第一设备101有多种情况，例如可以是在第一设备101身份认证通过时下发，或第一设备101在必要时向服务器发送获取无线通道连接点的请求，服务器在收到该请求时下发等。
第一设备101从服务器接收的无线通道连接信息可以是建立其中一种短距离无线通道所需要的信息，也可以是两种或以上的无线通道连接信息。根据所下发的无线通道连接信息不同，在执行S202时，第一设备101建立短距离无线通道的过程可以不同。
例如，第一设备101收到的是其中一种无线通道连接信息(例如SSID及WIFI密码)，则第一设备101根据收到的无线通道连接信息中的连接点标识(例如SSID)搜索是否有匹配的连接点，如果有，则将无线通道连接信息(例如，WIFI密码和SSID)发给第二设备102，请求建立连接。当建立起第一短距离无线通道后，再通过已建立的第一短距离无线通道建立第二短距离无线通道(可参见下文S201c部分描述)。
再例如，如果第一设备101收到的是不止一种无线通道连接信息(例如SSID及WIFI密码、MAC地址及蓝牙密码)，则可以根据所收到的无线通道连接信息直接建立不止一 个无线通道。建立完成后，如果还有其他待建立的无线通道连接信息，则可通过已建立的连接通道(例如已连接的有线通道a、无线移动通道b，以及其中一条已建立的短距离无线通道c)来获取相应的无线通道连接信息。具体过程根据所选择的通道类型可参见本申请S201a/S 201b/S201c中相应内容。
S201b、通过已建立的有线通道a来获取无线通道连接信息。
作为一个实施例，在服务器对建立短距离无线通道所涉及的设备身份验证通过后，可以通知第一设备101和第二设备102；或者由第一设备101将自身的身份验证标识携带在请求中发给第二设备102请求身份验证。第二设备102在获得验证通过的消息后，可以通过已连接的有线通道a向第一设备101发送无线通道连接信息，所发送的无线通道连接信息可以是其中一种待建立的短距离无线通道所对应的信息，也可以是两种或两种以上待建立的短距离无线通道所对应的信息。
第一设备101在收到无线通道连接信息后建立一条或多条短距离无线通道。建立完成后，如果还有其他待建立的无线通道连接信息，则可通过已建立的连接通道(例如已连接的有线通道a、无线移动通道b，以及其中一条已建立的短距离无线通道c)来获取相应的无线通道连接信息。具体过程可参见本申请S201a/S 201b/S201c相应部分内容。
S201c、通过其中一个已建立的短距离无线通道c来获取无线通道连接信息。
当第一设备101与第二设备102之间已经建立有一条或一条以上的短距离无线通道c，如果还有其他待建立的短距离无线通道，则第二设备102通过已建立的短距离无线通道将至少一条待建立的短距离无线通道所对应的无线通道连接信息发给第一设备101。第一设备101通过已建立的短距离无线通道收到无线通道连接信息后，搜索到与所接收到的连接点标识相匹配的连接点(如果需要输入连接密码，则将连接密码发送给第二设备102)，建立相应的短距离无线通道。
通过上文S201a、S 201b、S201c部分的揭示，可以看出，当选择不同的已建立的连接通道传输不同数量的短距离无线通道时，建立多条短距离无线通道的过程可以不同。举例来说，可以通过同一条已建立的连接通道接收到所有待建立的无线通道连接信息，则第一设备101可以直接建立多条短距离无线通道。可以在未建立任何一条短距离无线通道前，通过无线移动通道从服务器接收至少一种无线通道连接信息，或通过有线通道从第二设备102接收至少一种无线通道连接信息；在建立至少一条短距离无线通道后，通过其中一条短距离无线通道从第二设备102接收下一个待建立的短距离无线通道无线所对应的通道连接信息。各种设计流程可依据业务需求发生变化，在此不再一一列 举。
某些业务场景可以在建立某个短距离无线通道时验证连接密码。连接密码发送给第一设备101的流程可以根据实际的业务场景有所区别，在某些场景，可以在执行步骤201时，将连接密码和连接点标识一同打包在无线通道连接信息中发送给第一设备101；在另一些场景，连接密码和连接点标识可以是不同的获取流程。以下列举几种不同的处理流程作为示例性的描述，但并不局限于所列的几种流程。
例如，当用户首次建立无线通道连接时，可以将连接密码和连接点标识打包后发给第一设备101。
再例如，用户可以在首次获取到连接密码和连接点标识后仅对连接点标识进行存储，当下一次用户与该连接点标识所对应的连接点建立短距离无线连接时，第一设备101再次请求连接密码，此时再通过已建立的连接通道将与连接点标识所对应的连接密码发给第一设备101。
另外，连接密码还可以是通过某种方式事先存储在第一设备101本地，当第一设备101获取到连接点标识后，根据连接点标识与连接密码的对应关系在本地查找所对应的连接密码。举例来说，可以在第一设备101登录服务器时将连接密码下载到本地存储，连接密码可以带有识别该连接密码的标签，当服务器下发给第一设备101连接点标识时，可以将所对应的连接密码的标签一起下发给第一设备101，第一设备101根据标签获取所存储的连接密码等等。
图3是本申请实施例中作为被连接设备的第二设备102的工作流程图示。
S301，将第二设备102的至少一种无线通道连接信息通过已建立的连接通道发送给第一设备101。需要说明的是，通过服务器执行S301的过程在上文S201a部分已经描述，在本例中不再重复揭示。无线通道连接信息的相关定义可参考上文中的描述。
S302，当接收到第一设备101发送的无线通道连接信息时，如果所接收到的连接点标识与本设备上的连接点标识相匹配，则根据无线通道连接信息建立该连接点与第一设备101的短距离无线通道。
除图3所示的步骤，在某些对安全性有一定要求的场合中，本申请可以通过身份验证来保证安全性，在建立短距离无线通道前，可以验证建立短距离无线通道所涉及到的设备的合法性。如果身份验证通过，则第二设备102可以发送无线通道连接信息。
与上文S201a、S201b、S201c所揭示的方案相呼应，在不同的情况下第二设备102在S301的执行过程不同。从上文的描述可以看出，无线通道连接信息可以按照S201a 部分揭示的内容由服务器发给第一设备101，也可以通过第二设备102将无线通道连接信息发给第一设备101。因此，作为例子，第二设备102可以执行以下S301a、S301b、S301c的过程。
S301a，第二设备102可以将无线通道连接信息通过无线移动通道上传给服务器，再由服务器通过无线移动通道发给第一设备101。例如，可以在第二设备102登录服务器时上传无线通道连接信息，当然也可以在服务器通知第二设备102时执行上传的动作。根据实际业务场景的需要，第二设备102可以上传一种或一种以上的无线通道连接信息。
第二设备102还可以执行S301b所揭示的过程。
S301b，服务器在对建立短距离无线通道所涉及的设备身份验证通过后，通知第二设备102，第二设备102通过已建立的有线通道将至少一种无线通道连接信息发给第一设备101。
第二设备102也可以执行S301c所揭示的过程。
S301c，第一设备101可以通过已经建立的短距离无线通道c请求第二设备102发送无线通道连接信息，第二设备102在收到请求后，将相应的无线通道连接信息通过已建立短距离无线通道c发送给第一设备101。
需要说明，第一设备101所完成的功能和第二设备102所完成的功能也可以同时集成于同一台设备，该设备在执行不同的角色时分别完成第一设备101的功能或第二设备102的功能。
在一个例子中，可以将上文图2、图3描述的过程应用于初次建立各个短距离无线通道时，当某个短距离无线通道被建立后，第一设备101可以保存该短距离无线通道的无线通道连接信息，以便下一次与第二设备102连接该连接点时可以自动建立连接，相关过程可参考现有技术的类似流程。
图4是本申请一个应用实例的图示。在本例中将本申请的方案应用于互联网汽车系统400中。系统400基于安卓操作系统或其他可开放自动录入无线通道连接信息的操作系统。
系统400中包括手机401、车机402、云服务器403。手机401和车机402既可以完成第一设备101的功能，也可以完成第二设备102的功能。图4中仅描述手机401作为第一设备401、车机402作为第二设备402的流程。本例中所需要建立的短距离无线通道包括WIFI通道和蓝牙通道。
手机401和车机402借助本机上的App应用，分别通过无线移动通道(以下以4G 通道为例进行描述)与云服务器403交互。另外，手机401上的应用可以根据手机401上打开的短距离无线功能的数量来控制待建立的待建立短距离无线通道的数量，本例中用户可提前打开WIFI和蓝牙连接接口，应用检索到WIFI和蓝牙的连接接口后设置目前待建立的短距离无线通道为WIFI和蓝牙通道。
在S401阶段，车机402通过登录云服务器403，将WIFI的连接点标识和WIFI密码上传给云服务器403。
在S402阶段，驾驶者首次打开手机401上的应用时，手机401通过应用将账户及密码发给云服务器403，请求登录。
在S403阶段，云服务器403验证手机401发送的账户与车机登录时所使用的账户是否一致，如果一致，则验证通过，然后将所保存的车机402的WIFI连接点标识和WIFI密码发给手机401。
在S404阶段，手机401根据收到的WIFI连接点标识和WIFI密码向车机402发起WIFI连接。
在S405阶段，车机402验证WIFI密码通过后，响应手机401的连接请求，建立WIFI通道成功。
在S406阶段，手机401通过已建立的WIFI通道向车机402请求MAC地址及蓝牙密码，并将自身的账户信息发给车机402。
在S407阶段，车机402验证手机401的账户与本机登录云服务器403的账户相同，则将MAC地址和蓝牙密码通过WIFI通道发给手机401。
在S408阶段，手机401将MAC地址和蓝牙密码发给车机402请求连接蓝牙通道。
在S409阶段，车机402验证蓝牙密码后与手机401建立WIFI连接。
除S401-409阶段所描述的过程，手机401还可以在建立成功WIFI通道后，保存WIFI连接点标识和WIFI密码；在建立成功蓝牙通道后，保存车机402的MAC地址和蓝牙密码。手机401还可以在WIFI通道或蓝牙通道建立失败时，通过App提示用户人工选择连接点标识，并手工录入连接密码来再次尝试连接。
与前述建立短距离无线通道的方法的实施例相对应，本申请还提供了建立短距离无线通道的装置的实施例。
本申请建立短距离无线通道的装置的实施例可以应用在手机、车机、电视、手表等智能设备上。装置实施例可以通过软件实现，也可以通过硬件或者软硬件结合的方式实现。以软件实现为例，作为一个逻辑意义上的装置，是通过其所在智能设备的处理器将 非易失性存储器中对应的计算机程序指令读取到内存中运行形成的。从硬件层面而言，如图5所示，为本申请建立短距离无线通道的装置所在智能设备的一种硬件结构图，除了图5所示的处理器、内存、网络接口、以及非易失性存储器之外，实施例中装置所在的智能设备通常根据该智能设备的实际功能，还可以包括其他硬件，对此不再赘述。
