技术领域
本发明涉及无线通信技术领域，尤其涉及一种建立通信连接的方法、设备及系统。
背景技术
Wi-Fi P2P(无线点对点)技术是一种基于点对点的Wi-Fi Direct技术，是指允许无线设备以点对点形式实现互连，无需通过无线路由器即可相互连接以及连接后的数据传输。两个无线设备需要建立Wi-Fi P2P连接时，一个处于搜索状态的设备以广播形式向周围所有设备发送请求，所有接收到请求的设备要向其发送响应信息，该设备根据相应信息选择期望连接的设备，进而建立Wi-Fi P2P连接。因此，现有技术是以非定向的方式发送请求，等待周围所有设备的响应后从中选择，增加了网络连接时间，连接效率低。
发明内容
有鉴于此，本发明实施例提供了一种建立通信连接的方法、设备及系统，能够有效减少两个设备之间建立连接的时间，提高连接效率。

具体实施方式
为了更好的理解本发明的技术方案，下面结合附图对本发明实施例进行详细描述。
终端设备建立通信连接的过程中，当两个设备在建立点对点通信连接时，一个处于搜索状态的设备以广播形式向周围其他设备发送请求，然后等待接收到请求的其他设备要发送响应信息，该设备从发送响应信息的设备中选择希望连接的设备，建立通信连接，由于这种非定向搜索建立通信连接的方式，需要等待搜索到的周围所有设备的响应后才能选择建立连接的设备，增加建立通信连接的时间。因此，为了解决该问题，本发明实施例提供了一种建立通信连接的方法，该方法应用于具有接收建立通信连接的目标角色设备中，如图1所示，包括：
101、向第一指定设备发送自身的目标设备属性信息，以使得第一指定设备将获取到所述目标设备属性信息携带于第一探测消息中，并广播所 述第一探测消息。
其中，第一指定设备是指建立通信连接的两个设备中发起建立通信连接的设备。每一台设备都要自己的设备属性信息，该属性信息是一种身份信息，用于区分每一台设备，该属性信息可以包括设备的类型信息、指定的识别信息、属性地址等信息。例如，设备属性信息可以是设备的MAC(Media Access Control，多媒体访问控制)地址，设备的SSID(Service Set Identifier，服务集标识)。
其中，第一探测消息是建立通信连接的发起设备在与其他设备建立通信连接时向其他设备发送的请求信息。
需要说明的是，该探测信息是以数据帧的形式在信道1或信道6或信道11中，进行广播传送的。而设备属性信息基于P2P(peer to peer,点对点通信)协议的格式，封装在探测信息对应的数据帧中。其中，该数据帧包括三个部分：数据帧头、数据部分以及数据帧尾。数据帧头和数据帧尾包括一些控制信息，该控制信息中包括接收该数据帧设备的地址定位以及其他网络信息；数据部分为数据主体，承载了消息的主要内容，例如，该探测信息对应的数据中，数据帧头和数据帧尾包括期望建立通信连接的设备的地址定位信息，而其数据部分承载着上述设备建立通信连接的请求以及通信传输协议等数据信息。
102、当监测到第一探测消息时，从第一探测消息中解析目标设备属性信息。
由于该第一探测消息以数据帧形式进行传输的，因此，当该设备监听到第一探测信息后，设备将监听的第一探测消息的数据帧进行解压处理后，从而解析出该第一探测消息中携带的第一设备属性信息。
103、当解析到的目标设备属性信息与自身设备属性信息匹配时，向第一指定设备回复第一探测响应消息。
补充说明的是，当解析到的目标设备属性信息与自身设备属性信息不匹配时，该设备不响应该探测信息，对第一指定设备不做回复。
104、与第一指定设备建立通信连接。
优选地，本实施例中的通信连接是指该设备与第一指定设备建立点对点连接，并且在建立点对点连接时，还需要确定自身的角色信息以及第一指定设备的角色信息，然后设备之间进行身份认证信息的交互，根据协商好的角色，按照Wi-Fi P2P的标准握手协议建立无线网络连接。其中，设备间角色的确定以及身份认证的操作遵循现有技术。
本发明实施例提供了一种建立通信连接的方法，向第一指定设备发送自身的目标设备属性信息，以使得第一设备将获取到所述第一设备属性信 息携带于第一探测消息中，并广播所述第一探测消息，通过监测到建立通信连接的指定设备发送的第一探测消息，从第一探测消息中解析目标设备属性信息，而当解析到的目标设备属性信息与自身设备属性信息匹配时，向第一指定设备回复第一探测响应消息，从而，与第一指定设备建立点对点连接。相比于现有技术，两个设备在建立Wi-Fi P2P连接时，以非定向的方式发送请求信息，等待其他设备响应后在从中选择出建立连接的设备，本发明实施例提供的方法通过将期望建立连接的目标设备属性信息携带在第一探测消息中，设备将探测信息中的第一设备属性信息与自身设备属性信息进行匹配，从而，采用定向搜索的方式建立通信连接，进而减小网络连接时间，提高网络连接效率。另一方面，通过本发明实施例提供的定向搜索过程中，只有对应的目标设备才回复，这样建立网络连接的过程中，更好的保护网络连接的安全性。
进一步，当该设备与第一指定设备建立了Wi-Fi点对点连接，建立连接的设备之间还可以分享自身连接的网络路由信息，基于此目的，本发明实施例提供了两种可能的实现方式。
需要说明的是，建立Wi-Fi点对点连接的终端设备支持基站和Wi-Fi P2P共存的并发模式，即设备在建立Wi-Fi P2P的过程中，不需要与网络接入点断开，而设备与网络接入点之间进行无线连接时，也不需要与建立Wi-Fi P2P网络连接的设备断开连接。
第一种实现方式，该设备将自身连接网络的信息发送给第一指定设备，该方法的方法流程图如图2所示，包括：
105、通过已建立的Wi-Fi点对点通信方式发送设备连接的路由信息，以使得所第一指定设备连接所述路由信息对应的无线网络。
第二种实现方式，第一指定设备将自身连接网络的信息发送给该设备，该方法的方法流程图如图3所示，包括：
106、通过已建立的Wi-Fi点对点通信方式，接收所述第一指定设备发送的路由信息。
107、根据所述接收的路由信息，连接与所述路由信息相对应的无线网络。
采用上述两种实现方式中的任意一种，都能够使得两个设备中的一个设备快速连接到另一个设备已经建立的无线网络中，整个过程不需要用户干预就可以自动完成，这样采用本实施例提供的通信连接方法建立两个设备之间的Wi-Fi点对点连接后，即使其中一个设备被拿开，并超过了这两个设备之间能够实现Wi-Fi点对点通信的距离，也可以通过共享的路由信息，通过无线网络的形式保持两个设备间的通信。
进一步，为了实现定向搜索建立通信网络连接的操作，在该设备监听到的第一探测消息中增加设备属性信息，基于此目的，本发明实施例提供了一种可能的实现方式，在探测信息中配置有设备属性字段，该设备属性字段用于承载目标设备属性信息，其中，该设备属性字段包括：
属性地址字段，用于指示点对点通信类型。
长度指示字段，用于指示设备地址字段的长度。
设备地址字段，用于承载目标设备属性信息。
具体的，设备属性字段如表1所述：
Figure PCTCN2017115530-appb-000001
表1
上述表1中设备属性字段中的每一类字段表示的含义如下：
属性地址字段(Attribute ID)，长度为1个字节，值固定为3，代表该内容是Device ID的内容；长度指示字段(Length),长度为2个字节，值固定位6，代表设备地址的内容是6个字节的；设备地址字段，长度为6个字节，代表要搜索的目标设备的MAC地址。
进一步，结合上述操作方法，为了使得第一指定设备获取到目标设备属性信息，针对于向第一指定设备发送自身的目标设备属性信息，本发明实施例提供了一种可能的实现方法流程如图4所示，具体包括：
201、按照指定方式，与所述第一指定设备建立专用通信连接。
在具体的实现过程中，按照指定方式，与所述第一指定设备建立专用通信连接实现方式可以有多种。
例如，上述建立通信连接的两个设备都设置有NFC(Near field communication，近距离无线通信)芯片，近场通信芯片具有在相距20厘米范围内允许电子设备之间进行非接触式数据交换、传输的作用，因此，当建立通信连接的两个设备彼此靠近时，建立近场通信连接，从而进行数据交互。
或者，建立通信连接的两个设备都设置有红外通信的功能，其中，这 种通信方式都用于短距离数据交换中。发起设备和目标设备的红外通信功能都开启时，目标设备向外辐射红外线波，该红外线波承载有目标设备的设备属性信息，然后发起设备的红外通信功能的接收该红外线光波，实现数据的传输交互。
又或者，建立连接的两个设备都开启蓝牙功能，通过蓝牙配对，然后利用蓝牙功能进行数据的交互。其中，蓝牙功能也用于短距离数据交互中。
需要说明的是，以上举例仅为按照指定方式与所述第一指定设备建立专用通信连接中的三种具体的实现方式，其中，按照指定方式与所第一指定设备建立专用通信连接的方式包括近场通信、红外通信、蓝牙通信，但是并不限于这三种方式。
202、通过专用信道向所述第一指定设备传输自身的目标设备属性信息。
进一步，信息的传输需要一定的时间，在信息传输过程中存在着由于某些原因第一指定设备没有接收到该设备回复的第一探测响应消息，造成该设备与第一设备无法建立通信连接，针对此问题本发明实施例提供例一种可能的解决方法，如图5所示，具体包括：
108、通过所述专用信道协商建立Wi-Fi点对点连接时所需的设备角色信息。
具体举例说明通过专用信道协商建立Wi-Fi点对点连接时所需的设备角色信息的过程，其中，该设备为目标设备，第一指定设备为建立通信连接的发起设备。具体实现过程包括：发起设备与目标设备通过专用信道交互准备启动Wi-Fi P2P网络连接建立的请求命令，然后发起设备中的网络模块向该设备的处理器发送Wi-Fi direct group owner(Wi-Fi P2P通信连接的发起者)角色的热点信息，相应的该设备将自身的Wi-Fi P2P通信连接接受者角色的信息通过专用信道传输给发起设备，发起设备的建立专用信道的功能模块接收该角色信息，并发送给发起设备的处理器。
需要说明的是，若发起设备的建立专用信道的功能模块不能与自身的处理器进行信令交互，上述设备角色信息的协商的实现也可以由目标设备来完成；若目标设备的建立专用信道的功能模块也不能与自身的处理器进行信令交互，则直接结束Wi-Fi P2P，提示连接失败。
109、在所述设备角色信息协商完成后，基于已确定的设备角色信息，与所述第一指定设备建立点对点连接。
进一步，结合上述任一种建立通信连接的方法，该方法还可以用于建立通信连接的发起角色设备中，基于此目标，本发明实施例还提供了另一种可能的实现方式，如图6所示，该方法还包括：
301、监测其他指定设备发送的其他指定设备自身的目标设备属性信息。
其中，其他指定设备是指建立通信连接的两个设备中的目标设备。
其中，该设备监测其他指定设备发送的其他指定设备自身的目标设备属性信息可以通过该设备与其他指定设备按照指定方式建立的专用信道监测其他指定设备发送的其他指定设备自身的目标设备属性信息。上述建立专用信道的指定方式包括但不限于近场通信、红外通信、蓝牙通信的方式。
302、将所述其他指定设备自身对应的目标设备属性信息携带在第二探测信息中，广播第二探测信息。
其中，将其他指定设备自身对应目标设备属性信息携带于第二探测消息中的方法与将该设备自身的目标设备属性信息携带在第一探测消息中的方法一样，且第二探测消息中设置的设备属性字段与第一探测消息中的设备属性字段的组成结构相同，因此，这里不再赘余。
其中，第二探测消息也在信道1或信道6或信道11中，进行广播传送的
303、当接收到其他指定设备回复的第二探测响应信息时，与所述其他指定设备建立通信连接
需要说明的是，上述实施例中步骤101至109是该设备作为建立通信连接的目标接收角色设备，与作为发起角色设备建立通信连接的执行过程；而步骤301～步骤303是该设备作为建立通信连接发起角色设备时，向作为目标接收角色的其他设备发起建立通信连接的执行过程，该设备作为目标接收角色设备执行建立通信连接的过程与作为发起角色设备执行建立通信连接的过程是两个独立的过程。
补充说明的是，本发明实施例中提及的与执行上述任一实施例中执行设备建立通信连接是的第一指定设备和其他指定设备可以为同一个指定设备，也可以是不同的指定设备。当第一指定设备与其他指定设备为同一指定设备时，假设执行上述实施例的设备作为目标接收角度设备与作为发起角色的第一指定设备(其他指定设备)在建立通信连接时，上述实施例的执行设备与第一指定设备发生角色互换，即第一指定设备作为目标接收角色设备，执行设备作为发起角色设备，两个设备在建立通信连接时，需要先断开该执行设备作为目标接收角色设备执行建立通信连接的过程，才能执行该执行设备作为发起角色设备执行建立通信连接的过程，实现两个设备角色互换后完成点对点连接的建立。另外，该执行设备作为目标接收角色设备执行建立通信连接的过程，与建立通信连接的设备发生角色互换 时，其操作处理的方式与上述角色互换后的建立点对点连接的方式相同。
基于上述定向搜索建立通信连接的方法，结合用户实现移动打印时，设备之间建立连接关系的过程为例，具体说明设备建立通信连接的方法。其中，建立通信连接的第一指定设备为图像形成设备，如打印机；目标设备为手机终端。如图7所示，为图像形成设备与手机终端建立通信连接的流程示意图，该方法具体包括：
步骤1、手机终端向图像形成设备发送自身的目标设备属性信息，以使得图像形成设备将获取到所述第一设备属性信息携带于第一探测消息中，并广播所述第一探测消息。

步骤2、当手机终端监测到第一探测消息时，从第一探测消息中解析目标设备属性信息。
步骤3、当手机终端解析到的目标设备属性信息与自身设备属性信息匹配时，向图像形成设备回复第一探测响应消息。
补充说明的是，当手机终端从第一探测消息中解析的目标设备属性信息与自身的设备属性信息不匹配，该手机终端对此探测信息不做回复，该手机终端与此图像形成设备不会建立Wi-Fi点对点连接。
步骤4、手机终端与图像形成设备建立点对点连接。
其中，当图像形成设备由于某些原因没有接收到手机终端回复的第一探测响应消息时，还包括：
步骤5、手机终端与图像形成设备通过所述专用信道协商建立Wi-Fi点对点连接时所需的设备角色信息。
步骤6、在所述设备角色信息协商完成后，基于已确定的设备角色信息，与所述图像形成设备建立点对点连接。

步骤8、通过已建立的Wi-Fi点对点通信方式，手机终端接收所述图像设备发送的路由信息。
步骤9、手机终端根据所述接收的路由信息，连接与所述路由信息相对应的无线网络。
需要说明的是，本实施例仅为实施例提供的建立通信连接的方法中的 其中一种具体实现方式，并不用以限制本申请。
本发明实施例提供了一种建立通信连接的方法，向第一指定设备发送自身的目标设备属性信息，以使得第一指定设备将获取到所述第一设备属性信息携带于第一探测消息中，并广播所述第一探测消息，通过监测到建立通信连接的第一指定设备发送的第一探测消息，从第一探测消息中解析目标设备属性信息，而当解析到的目标设备属性信息与自身设备属性信息匹配时，向第一指定设备回复第一探测响应消息，从而，与第一指定设备建立点对点连接。相比于现有技术，两个设备在建立Wi-Fi P2P连接时，以非定向的方式发送请求信息，等待其他设备响应后在从中选择出建立连接的设备，本发明实施例提供的方法通过将期望建立连接的目标设备属性信息携带在第一探测消息中，设备将探测信息中的第一设备属性信息与自身设备属性信息进行匹配，从而，采用定向搜索的方式建立通信连接，进而减小网络连接时间，提高网络连接效率。另一方面，通过本发明实施例提供的定向搜索过程中，只有对应的目标设备才回复，这样建立网络连接的过程中，更好的保护网络连接的安全性。
基于上述用户实现移动打印时，设备之间建立连接关系的实施例，上述手机终端设备也可以向图像形成设备发起建立通信连接的信息，从而建立连接。其中，手机终端为建立连接的发起设备，图像形成设备为建立连接的目标设备。如图8所示，为本发明实施例还提供了另一种可能的实现方法的流程示意图，该方法还包括：
步骤10、手机终端监测图像形成设备发送的第二目标设备属性信息。
其中，手机终端通过手机终端与图像形成设备利用指定方式近场通信、红外通信、蓝牙通信等方式建立专用信道监测图像形成设备发送的设备属性信息。
步骤20、手机终端将所述图像形成设备的设备属性信息携带在第二探测信息中，广播第二探测信息。
其中，将图像形成设备的设备属性信息携带于第二探测消息中的方法与将手机终端的设备属性信息携带在第一探测消息中的方法一致，且第二探测消息中设置的设备属性字段与第一探测消息中的设备属性字段的组成结构相同，因此，这里不再赘余。
其中，第二探测消息也在信道1或信道6或信道11中，进行广播传送的
步骤30、手机终端当接收到图像形成设备回复的第二探测响应信息时，与图像形成设备建立点对点通信连接。
需要说明的是，本实施例仅为实施例提供的建立通信连接的方法中的 其中一种具体实现方式，并不用以限制本申请。
本发明还提供了另一实施例中，如图9所示，在上述的步骤104：“与第一指定设备建立网络连接”中的网络连接除了上述实施例中的“点对点连接”，也可以是Wi-Fi连接；例如上述的目标设备属性信息包括路由器的“SSID和密码”，第一指定设备和路由器在步骤S101-S103基础上，建立Wi-Fi连接。
基于上述定向搜索建立Wi-Fi连接的方法，下面也结合用户实现移动打印时，进一步补充说明：

步骤1003、当目标设备(信号强度最强的路由器)解析到的目标设备属性信息与自身设备属性信息匹配时，向图像形成设备回复第一探测响应消息。
补充说明的是，当其他路由器从第一探测消息中解析的目标设备属性信息与自身的设备属性信息不匹配，其他路由器对此探测信息不做回复，其他路由器与此图像形成设备不会建立Wi-Fi连接。
步骤1004、目标设备(信号强度最强的路由器)与图像形成设备建立Wi-Fi连接。
本实施例提供的通过定向搜索建立Wi-Fi连接之后的其他步骤，在上述实施例的基础上只需要将“Wi-Fi连接”替换为“Wi-Fi点对点连接”，同样也适用于本实施例的步骤、方法、设备和系统，在此不再赘述。
基于上述建立通信连接的方法，本发明实施例提供了一种建立通信连接的设备，该设备能够与建立通信连接的发起设备建立点对点连接，该设备用于向建立通信连接的发起设备发送自身的目标设备属性信息，以使得建立通信连接的发起将获取到所述第一设备属性信息携带于第一探测消息中，并广播所述第一探测消息。其中，该设备的结构框图如图10所述，包括：
