  • Wi-Fi P2P is a Wi-Fi peer-to-peer (P2P) standard launched by the wireless fidelity (Wi-Fi) alliance. Wi-Fi P2P connections are created on demand when users initiate P2P services. Typically, this process takes 3.5 to 20 seconds.

背景技术
在没有局域网或互联网的情况下，Wi-Fi P2P仍支持两个设备之间的互连及数据的高速传输，因此Wi-Fi P2P在诸如无线投屏、文件共享等方面得到广泛应用。但现有的Wi-Fi P2P在两个设备的连接建立阶段耗时较长且耗时时长不稳定，用户体验不好。
发明内容
为了解决上述技术问题，本申请提供了一种Wi-Fi P2P连接方法、电子设备及计算机可读存储介质；能够缩减两个设备的连接建立阶段的耗时时长，保持该耗时时长的稳定性，提升用户体验。

具体实施方式
下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚、完整地描述。以下实施例中所使用的术语只是为了描述特定实施例的目的，而并非旨在作为对本申请的限制。如在本申请的说明书和所附权利要求书中所使用的那样，单数表达形式“一个”、“一种”、“所述”、“上述”、“该”和“这一”旨在也包括例如“一个或多个”这种表达形式，除非其上下文中明确地有相反指示。还应当理解，在本申请实施例中，“一个或多个”是指一个、两个或两个以上；“和/或”，描述关联对象的关联关系，表示可以存在三种关系；例如，A和/或B，可以表示：单独存在A，同时存在A和B，单独存在B的情况，其中A、B可以是单数或者复数。字符“/”一般表示前后关联对象是一种“或”的关系。

本申请实施例涉及的多个，是指大于或等于两个。需要说明的是，在本申请实施例的描述中，“第一”、“第二”等词汇，仅用于区分描述的目的，而不能理解为指示或暗示相对重要性，也不能理解为指示或暗示顺序。
为了更清楚地阐明本申请技术方案，下面对本申请涉及的相关概念进行解释。
信道，是指信号在通信系统中传输的通道，由信号从发射端传输到接收端所经过的传输媒质所构成。根据IEEE 802.11协议，2.4GHz Wi-Fi频段被划分为13个交叠的信道，每个信道的宽度是22MHz(IEEE 802.11g标准和IEEE 802.11n标准中每个信道频宽是20MHz，IEEE 802.10B标准中每个信道频宽是22MHz)；5GHz Wi-Fi频段被划分了201个信道。
Wi-Fi P2P是无线保真(wireless fidelity，Wi-Fi)联盟(alliance)推出的Wi-Fi端对端(peer-to-peer，P2P)标准。Wi-Fi P2P连接都是在用户发起P2P业务时才按需创建的，典型情况下该过程耗时3.5～20s。Wi-Fi P2P连接的模式可包括：
方式一、标准模式(standard)
标准模式下的Wi-Fi P2P连接初始化包含发现(discovery)、组所有者(group owner,GO)协商、供应(provisioning)以及IP地址初始化4个关键过程。其中，完成discovery过程后，被发现设备即可显示在发现设备上，并等待用户选择。具体的，discovery过程包含扫描(scan)和发现(find)2个过程。find过程包含搜索(search)和侦听(listen)过程，search和listen来回循环，直至发现对方设备，或被对方设备发现。通常来说，scan是全信道扫描。scan的全信道扫描通常耗时900毫秒(ms)～2秒(s)，search和listen过程通常耗时200ms～10s。search和listen过程的最短耗时和最长耗时相差较大，主要是因为Wi-Fi P2P双方采用时分机制，search的耗时不稳定。
标准模式的最大局限性是scan和find都采用信道切换方式在不同信道发送探查请求(probe request)。其中，要想让对方发送请求响应，需要接收方与发送方处于相同信道。而双方在协商之前并不知晓对方使用的信道，因此会导致双方中的至少一方更换信道重复 发送probe request，如此循环，直至发现对方设备或被对方设备发现。因此，整个过程耗时较长且整体耗时不稳定。
示例性的，若发送方当前向接收方发送协商请求的信道为a信道，接收方当前接收协商请求的信道为b信道。由于接收方与发送方当前所使用的信道不是同一个信道，因此发送方设备通过a信道发送的协商请求，接收方无法通过b信道接收到，从而接收方无法响应该协商请求。发送方更换信道，接收方也可能更换信道，双方再次协商。发送方和接收方中的至少一个，可能多次更换信道，如此重复，直至最终双方信道相同，接收方接收到发送方发送的协商请求。这样，导致整个过程耗时较长且整体耗时不稳定。
由上可知，标准模式的discovery耗时较长，且时长不稳定。另外，用户通常只能在发现设备经discovery发现被发现设备之后，才能进行设备选择。因此P2P业务的初始化耗时较长且时长不稳定，用户体验不好。
方式二、持续模式(persistent)
持续模式中首次连接之后可以持久化组(group)配置信息，后续连接可以省去GO协商过程。并且，Provisioning过程也得以简化。但是，持续模式增加了Invitation；并且持续模式的discovery过程与标准模式的discovery过程相同，并未简化；因而也会导致P2P业务的初始化耗时较长且时长不稳定，用户体验不好。
也就是说，Wi-Fi P2P连接的上述两种模式，都导致或可能导致Wi-Fi P2P连接的耗时较长，用户体验不好。
为了解决上述技术问题，本申请提供了一种Wi-Fi P2P连接方法、电子设备及计算机可读存储介质；能够缩减两个设备的连接建立阶段的耗时时长，保持该耗时时长的稳定性，提升用户体验。
接下来介绍，一个电子设备与另一电子设备之间的Wi-Fi P2P连接方法。为了易于区分电子设备和另一电子设备，避免名称上的混淆，在下面的介绍中，以移动设备替代电子设备，以电子设备替代另一电子设备。需要说明的是，这仅是为了便于区分名称，避免混淆所采用的，并不是用于限定设备的具体类型。比如，移动设备也可以为固定式的电子设备(如台式计算机等)。

需要说明的是，电子设备的ID可以不为SSID，也可以不为BSSID。比如，电子设备的ID为与电子设备的SSID或BSSID关联的标识，通过电子设备的ID能够查询到电子设备的SSID或BSSID。电子设备的ID也可以为与电子设备的SSID和BSSID关联的标识。
可选地，在接收到另一个输入(比如，语音输入、触摸输入等)后，移动设备结束初始设置步骤的流程。
可选地，若在一个预设时长(比如，1分钟)内，移动设备仍未接收到广播消息，则结束移动设备的初始设置步骤的流程。
图7A为本申请提供的Wi-Fi P2P连接方法的使用步骤中移动设备的一种实施例的流程示意图。如图7A所示，该流程可以包括：
S701a、移动设备接收到一个输入；
移动设备接收到一个输入的方式有多种。比如，在移动设备的可建立Wi-Fi P2P连接的设备显示界面上，用户对一个电子设备的图标进行选择(比如，点击，长按等)，此时移动设备接收到一个输入；或者，用户对着移动设备输入一个语音，此时移动设备接收到一个输入。
另外，电子设备的表面可设有NFC标签，或者与电子设备(比如，智能电视)配套的遥控设备上可设有NFC标签；在移动设备靠近电子设备上的NFC标签后，或者，在移动设备靠近遥控设备上的NFC标签后，移动设备也接收到一个输入。
S702a、响应于该输入，获取到电子设备的ID；
在移动设备接收到该输入后，移动设备获取到电子设备的ID。
示例性地，该电子设备的ID可以为电子设备的SSID、BSSID等标识，也可以为与电子设备的SSID、BSSID等标识关联的标识(即，根据该电子设备的ID，可查询到电子设备的SSID、BSSID等标识)。
S703a、在预设的存储器中，是否查询到电子设备的ID。
示例性地，移动设备在获取到电子设备的ID后，在预设的存储器中去查询，是否查询到电子设备的ID。若查询到电子设备的ID，则执行S704a。若查询不到电子设备的ID，则执行S706a。
S704a、从预设的存储器中，获取到该电子设备的Wi-Fi P2P连接信息；
示例性地，从预设的存储器的表1中，获取到电子设备的ID对应的信道、认证信息、地址信息等。
S705a、将自身的信道配置为电子设备的ID对应的信道，将自身配置为GC设备，按照Wi-Fi P2P连接信息中的认证信息、地址信息，与电子设备建立Wi-Fi P2P连接。
示例性地，移动设备将自身配置为GC设备，将自身的信道配置为电子设备的ID对应的信道，根据Wi-Fi P2P连接信息中的认证信息、地址信息，与电子设备(GO设备)建立Wi-Fi P2P连接。
示例性地，移动设备也可以先将自身的信道配置为电子设备的ID对应的信道，然后将自身配置为GC设备，之后根据Wi-Fi P2P连接信息中的认证信息、地址信息，与电子设备(GO设备)建立Wi-Fi P2P连接。
S706a、移动设备依次在每个信道上扫描。
若移动设备在预设的存储器中，没有查询到电子设备的ID，则移动设备依次在移动设备工作频段的每个信道上扫描。
示例性地，移动设备依次在移动设备支持的每个工作频段上的每个信道上扫描。
可选地，若移动设备支持M个工作频段，移动设备在第1个工作频段——第M个工作频段上的所有信道依次扫描。比如，移动设备支持2个工作频段，第1个工作频段上的信道数为N1个，第二个工作频段上的信道数为N2，则移动设备可以先在第1个工作频段的N1个信道上进行每个信道扫描，之后在第2个工作频段的N2个信道上进行每个信道扫描。
具体地，若移动设备支持2.4GHz频段和5GHz频段，移动设备可以先在2.4GHz频段上进行全信道扫描，之后再在5GHz频段上进行全信道扫描；移动设备也可以先在5GHz频段上进行全信道扫描，之后再在2.4GHz频段上进行全信道扫描。即移动设备可在其支持的所有频段上，依次对每个频段，进行每个信道的扫描。
可选地，若移动设备支持2.4GHz频段和5GHz频段，移动设备也可以先在当前工作的频段上进行全信道扫描，之后在另一频段上进行全信道扫描。
S707a、移动设备是否接收到电子设备发送的一个消息。
在扫描的过程中，若移动设备接收到电子设备发送的一个消息，则执行S708a；若移动设备没有接收到电子设备发送的一个消息，则执行S710a。在扫描的过程中，若移动设备接收到电子设备发送的一个消息，则说明移动设备当前的信道为电子设备使用的信道。
S708a、该消息是否包含电子设备的ID及电子设备的Wi-Fi P2P连接信息。
若移动设备确定该消息包含电子设备的ID及电子设备的Wi-Fi P2P连接信息，则执行S709a。
S709a、获取到电子设备的ID及电子设备的Wi-Fi P2P连接信息，并将获取到的上述信息存储在预设的存储器中。
移动设备从该消息中获取到电子设备的ID及电子设备的Wi-Fi P2P连接信息，并将获取到的上述信息存储在预设的存储器中。该预设的存储器可以为移动设备本地的存储器，也可以为移动设备以外的，与移动设备关联的存储器(比如，第三方存储设备)。
在S709a之后，执行S705a。
可选地，也可在S708a中，若移动设备确定该消息包含电子设备的ID及电子设备的Wi-Fi P2P连接信息，先执行S705a；之后，再执行S709a。即在S708a中，若移动设备确定该消息包含电子设备的ID及电子设备的Wi-Fi P2P连接信息，先将自身进行配置，与电子设备建立Wi-Fi P2P连接；之后，再将电子设备的ID及Wi-Fi P2P连接信息存储在预设的存储器中。
S710a，所有的信道是否都扫描完成。
若移动设备在S707a中没有接收到电子设备发送的消息，则移动设备确定所有的信道是否都扫描完成。
移动设备确定移动设备支持的所有工作频段上的所有信道是否都扫描完成。可选地，若移动设备支持两个工作频段，在一个工作频段上的所有信道都扫描完成后，可在另一个工作频段上扫描所有信道。上述两个工作频段只是示意性的举例。若移动设备支持M个工作频段(M为大于等于2的正整数)，可以在一个工作频段上的所有信道都扫描完成，且 未扫描完M个工作频段上的所有信道后，可在M个工作频段中的另外一个工作频段上进行全信道扫描，如此直至扫描完所有工作频段下的所有信道。
若所有的信道未扫描完成，则执行S706a。
可选地，还可在S710a中，若所有的信道都扫描完成后，移动设备确定此次Wi-Fi P2P连接失败。
可选地，在移动设备按照图7A示出的流程执行时，电子设备可按照图5示出的流程执行。比如，在移动设备执行S706a时，电子设备可执行S503。若电子设备未开机(比如，电源断开)，或者不再广播消息，则移动设备在S706a开始的全信道扫描，则不会在哪一个信道接收到该电子设备的一个消息；从而移动设备确定此次Wi-Fi P2P连接失败。
通过该方法，本申请实施例移动设备与电子设备在使用步骤中，移动设备在接收到一个输入后，获取到电子设备的ID，从预设的存储器中查找电子设备的ID对应的Wi-Fi P2P连接信息，从而移动设备可以获取Wi-Fi P2P连接信息中的信道、认证信息、地址信息，将自身的信道配置为该电子设备的ID对应的信道，按照Wi-Fi P2P连接信息中的认证信息、地址信息，与电子设备快速地完成Wi-Fi P2P连接，有效缩短移动设备与电子设备之间Wi-Fi P2P建立连接的时长。
图7B为本申请提供的Wi-Fi P2P连接方法的使用步骤中移动设备的一种实施例的流程示意图。如图7B所示，该流程可以包括：
S701b-S703b：分别与S701a-S703a相同，请参见S701a-S703a的描述；
S706b-S710b：分别与S706a-S710a相同，请参见S706a-S710a的描述；
S704b、从预设的存储器中，获取到该ID对应的Wi-Fi P2P连接信息，将自身的信道配置为Wi-Fi P2P连接信息中的信道，将自身配置为GC设备，并获取到Wi-Fi P2P连接信息中的认证信息和地址信息；
示例性地，从预设的存储器的表1中，获取到电子设备的ID对应的Wi-Fi P2P连接信息，并从中获取到信道、认证信息、地址信息等。
示例性地，移动设备将自身配置为GC设备，将自身的信道配置为电子设备的ID对应的信道，并根据获取到的Wi-Fi P2P连接信息中的认证信息、地址信息，准备与电子设备(GO设备)建立Wi-Fi P2P连接。
示例性地，移动设备也可以先将自身的信道配置为电子设备的ID对应的信道，然后将自身配置为GC设备，并根据获取到的Wi-Fi P2P连接信息中的认证信息、地址信息，准备与电子设备(GO设备)建立Wi-Fi P2P连接。
S705b、是否能与电子设备建立Wi-Fi P2P连接；
之后，判断能否与电子设备建立Wi-Fi P2P连接；若能，则执行S711b；若不能，则执行S706b。
之所以设置S705b，以及在S705b判断结果为否后，执行S706b；主要是考虑到有些电子设备或某个电子设备在一段时间后，可能会更改信道、认证信息和地址信息中的至少一项；这样，这些电子设备或某个电子设备的Wi-Fi P2P连接信息，可以通过全信道扫描的方式获取，并进行存储。并且，更改后的Wi-Fi P2P连接信息会覆盖之前的Wi-Fi P2P连接信息。
比如，电子设备A的ID为ID1，之前的Wi-Fi P2P连接信息中的信道、认证信息和地 址信息分别为：信道1、认证信息1和地址信息1；后来，出于某种原因(比如安全原因)，电子设备A的Wi-Fi P2P连接信息进行了更改；更改后的Wi-Fi P2P连接信息中的信道、认证信息和地址信息分别为：信道2、认证信息2和地址信息2。这样，就可以通过该方法，将更改后的Wi-Fi P2P连接信息存储在预设的存储器中。并且，更改后的Wi-Fi P2P连接信息会覆盖之前的Wi-Fi P2P连接信息。这样，在预设的存储器中，电子设备A的ID对应的Wi-Fi P2P连接信息就只有更改后的Wi-Fi P2P连接信息。这样，就提供了一种有效的自动更改方式。
可选地，也可以通过初始设置步骤，来进行Wi-Fi P2P连接信息的更改；达到同样的技术效果。
S711b、与电子设备建立Wi-Fi P2P连接。
该实施例的方法不仅实现了图7A中的技术效果，还进一步考虑了预设的存储器中存储的Wi-Fi P2P连接信息有更改的情况。针对移动设备获取到电子设备的ID对应的Wi-Fi P2P连接信息后，不能与电子设备建立Wi-Fi P2P连接的情形，通过全信道扫描的方式，获取到更改后的Wi-Fi P2P连接信息，并以覆盖之前Wi-Fi P2P连接信息的方式，存储在预设的存储器中。这样，在面对电子设备的Wi-Fi P2P连接信息更改的情形，可以自我判断、主动获取和存储，从而便于后续从预设的存储器中获取到最新的Wi-Fi P2P连接信息。
在未有特别说明的情况下，图7B对应的实施例中未阐述的内容与图7A对应的实施例中的相关内容相同。此处不再赘述。比如，图7B对应的实施例中表1的存储位置未有阐述，因此与图7A对应的实施例中的相关内容相同；因此，在图7B对应的实施例中，表1也是存储在预设的存储器中。
可替换地，也可不采用图7B所示的流程方法。比如，在图7A中的S709a中，在存储电子设备的ID及其对应的Wi-Fi P2P连接信息的时候，还将存储时间存储在预设的存储器中。在S703a和S704a中，在查询到多个该ID后，选取存储时间最晚(即最新)的对应关系或存储记录中的Wi-Fi P2P连接信息。这样，也能获取到另一电子设备更改后的Wi-Fi P2P连接信息。本领域技术人员熟知，该方案也在图7A所示的方法中。
示例性地，如图8所示，本申请实施例的Wi-Fi P2P连接方法中，基于Wi-Fi P2P连接信息，移动设备与电子设备建立Wi-Fi P2P连接的流程，可以包括：
S810、移动设备向电子设备发送Wi-Fi P2P接入请求。
在一种示例中，所述Wi-Fi P2P接入请求包含Wi-Fi P2P接入的密钥。
S820、电子设备验证是否正确。
若验证正确，则执行S830。
在一种实施方式中，若验证不正确，记录验证次数为1，并在等待一预定时长后，再次验证；若再次验证不正确，则验证次数加1。如此循环，若验证次数达到预设验证次数后，仍验证不正确，则停止验证。
在另外一种实施方式中，若验证不正确，则在等待一预定时长后，再次验证；若再次验证不正确，则向移动设备发送一个消息，告知移动设备Wi-Fi P2P接入的密钥错误；或者，电子设备通过语音输出或消息显示的方式，告知Wi-Fi P2P接入的密钥错误。
S830、电子设备向移动设备发送确认消息，确认Wi-Fi P2P建立连接。
移动设备接收到电子设备发送的确认消息。Wi-Fi P2P连接通道建立完毕。
需要说明的是，上述的S810-S830只是一种示意性说明。在移动设备与电子设备的Wi-Fi P2P通道建立过程中，可能存在多次类似上述S810-S830的循环过程。只是，移动设备向电子设备发送的消息，以及电子设备向移动设备发送的消息有所替换或变化。此处不再一一展开。
