Description

一种通信方法及设备
本申请要求于2014年08月27日提交中国专利局、申请号为201410429195.1、发明名称为“一种通信方法及设备”的中国专利申请，和于2014年09月01日提交中国专利局、申请号为201410440017.9、发明名称为“一种通信方法及设备”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本发明涉及通信技术领域，尤其涉及一种通信方法及设备。
背景技术
无线保真(Wi-Fi，Wireless Fidelity)，从1997年无线局域网标准IEEE802.11发布以来，在拥有众多在业界领先的公司组成的Wi-Fi联盟(Wi-Fi Alliance，WFA)的大力推动下，以其具有的部署快速、使用便利和传输速率高等优势，发展迅猛，由于现在的笔记本电脑、平板电脑和手机及许多电子终端设备等都支持Wi-Fi技术，因而Wi-Fi技术被广泛应用于各个行业。
Wi-Fi的一种网络结构为，具有无线接入设备，其他设备可以通过无线接入设备相互通信，这个无线接入设备可以称为基础设施，这种网络也可以称为基础设施网络，设备可以为终端设备，如手机，电视等，基础设施可以为家庭网关等。
Wi-Fi的另一种网络结构为，设备间直接进行通信，这种网络结构就叫做端到端网络，即点对点(Peer to Peer，P2P)网络，设备可以为终端设备，如手机，电视等。
综上可知，网络的连接由于使用网络的不同，存在以下不同网络结构的网络：一种是基于基本的802.11协议的基础设施的网络结构，另一种是基于P2P协议的P2P网络结构，这个P2P协议的可能情况可以为WFA的Wi-Fi Direct协议或NAN(Neighbor Awareness Networking,临近感知网络)协议等。
现有技术中，这两种网络结构是相互独立的，设备在进行业务的时候，根据具体情况，可以使用其中的一种网络结构。由于设备位置的变化会导致网络信号的变化，此时若固定在一种网络结构中进行业务，网络质量会出现高低起 伏的变化，用户体验不佳。

图1所示的实施例中，当第一设备连接的无线接入设备与第二设备在所述基础设施网络中连接的无线接入设备为同一个无线接入设备时，具体可以为多种方式，具体如下：
一、当第一设备连接的无线接入设备与第二设备在基础设施网络中连接的无线接入设备为同一个无线接入设备时，具体为：当第一设备确定自身已连接的无线接入设备的标识信息与第二设备在基础设施网络中连接的无线接入设备 的标识信息匹配时；
请参阅图2，本发明实施例中通信方法的另一个实施例包括：
201、第一设备接收第二设备通过P2P网络发送的第一消息；
可以理解的是，本步骤在第一设备和第二设备已经通过P2P网络传输业务的情况下进行，第一设备和第二设备均具有通过无线接入设备接入基础设施网络的能力，在本实施例中，第二设备通过与无线接入设备的连接接入基础设施网络。第一设备可以是连接在一个无线接入设备的，它能够知道自身已连接的无线接入设备的标识信息。
需要说明的是，在流程开始时，第二设备会向第一设备发送一个第一消息，该第一消息中包括第二设备在基础设施网络中的地址信息以及第二设备在基础设施网络中连接的无线接入设备的标识信息。
基础设施网络的一种网络结构为，具有无线接入设备，其他设备可以通过无线接入设备相互通信，这个无线接入设备可以称为基础设施，这种网络也可以称为基础设施网络，基础设施网络使用的协议可以是IEEE802.11协议。
基础设施网络的另一种网络结构为，设备间直接进行通信，这种网络结构就叫做点对点网络，即P2P网络，P2P网络是基于P2P协议建立起来的网络。
设备跟无线接入设备建立连接，即连接到基础设施网络，设备也可以跟其他设备建立P2P连接，即连接到P2P网络。
第二设备在基础设施网络中的地址信息可以是第二设备的MAC地址，也可以是第二设备的IP地址，还可以是第二设备的其他设备标识，如设备名称等，在实际应用中，也可以是MAC地址、或IP地址、或其他设备标识经过转化后的其他信息等，只要该地址信息能够利用来在基础设施网络中进行通信即可，具体此处不作限定。
第二设备在基础设施网络中连接的无线接入设备的标识信息可以为无线接入设备的MAC地址，在实际使用中，也可以是其他的标识信息，如无线接入设备的服务集标识(SSID，Service Set Identifier)等，此处不作限定。
无线接入设备可以是无线访问接入点AP，如无线路由器等，可以理解的是，在实际应用中，也可以是其他无线接入设备，如基站等，具体此处不作限定。
第一设备、第二设备可以是手机、平板电脑等移动终端，也可以是笔记本电脑等能够连接无线接入设备的设备，只要能够连接无线接入设备，能够连接 P2P网络即可，具体此处不作限定。
本发明各实施例中，P2P网络可以为Wi-Fi P2P网络(如Wi-Fi Direct网络，或者NAN网络)，对应的基础设施网络为Wi-Fi基础设施网络，可以理解的是，基础设施网络也可以为其他类型基础设施网络，P2P网络也可以为其他类型的P2P网络，除了它们之间需要对应外，此处不作具体限定。
以Wi-Fi网络环境下为例，即基础设施网络为Wi-Fi基础设施网络，P2P网络为Wi-Fi P2P网络(如Wi-Fi Direct网络，或者NAN网络)，在Wi-Fi的网络环境下，第一设备、第二设备均可以为支持Wi-Fi的终端设备，如第一设备可以为一个支持Wi-Fi的终端设备，比如支持Wi-Fi的手机；第二设备可以为一个支持Wi-Fi的终端设备，比如支持Wi-Fi的电视机。
在Wi-Fi的网络环境下，通过Wi-Fi P2P网络发送消息，是指第一设备和第二设备已经基于P2P协议建立起了Wi-Fi P2P通信，比如基于Wi-Fi Direct，协商出一个群主设备(GO，Group Owner)，一个群成员设备(Client)，群成员设备跟群主设备关联，协商密钥等，最终建立了Wi-Fi P2P连接，然后基于这个Wi-Fi P2P连接，一个设备给另一个设备发送消息；或者第一设备和第二设备都加入了NAN网络，基于NAN协议的机制进行通信，如收发NAN的同步信标帧、发现信标帧或服务发现帧等。
第二设备所发送的第一消息可以为Wi-Fi的帧，也可以是通过Wi-Fi携带的上层协议的数据包。第一消息中包括第二设备在基础设施网络中的地址信息以及第二设备在基础设施网络中连接的无线接入设备的标识信息，可以是通过帧的字段(Field)包括这些信息，也可以是帧的信息元素(IE，Information Element)包括这些信息，还可以是Wi-Fi携带的上层的数据包携带的，比如帧中有一个基础设施网络地址信息的字段或者信息元素，里面携带的是设备在基础设施网络中的地址信息，该地址信息可以是设备的MAC地址，比如帧中有一个无线接入设备标识信息的字段或者信息元素，该标识信息可以是无线接入设备的MAC地址，也可以是无线接入设备的服务集标识(SSID，Service Set Identifier)，还可以是其他形式的标识，具体此处不作限定。
第一设备可以是连接在一个无线接入设备的，它能够知道自身已连接的无线接入设备的标识信息，比如该无线接入设备的MAC地址或SSID。
202、第一设备判断自身已连接的无线接入设备的标识信息与第二设备在基 础设施网络中连接的无线接入设备的标识信息是否匹配，若是，则执行步骤203，若否，则结束流程；
第一设备判断自身已连接的无线接入设备的标识信息与第二设备在基础设施网络中连接的无线接入设备的标识信息是否匹配，当确定上述两个标识信息相同时可以认为它们是匹配的，在实际的应用中，也可以确定两个标识信息中某一个特征信息相同即可认为它们是匹配的，只要能够通过标识信息确定它们指的是同一个无线接入设备，则认为它们是匹配的，具体此处不作限定。
第一设备接收到第二设备发送的第一消息后，根据这个第一消息中包括的无线接入设备的标识信息，可以判断自己所连接的无线接入设备的表示跟接收到的标识信息是否匹配，当第一设备确定自身已连接的无线接入设备的标识信息与所述第二设备在基础设施网络中连接的无线接入设备的标识信息匹配时，可确定第一设备自身已连接上述基础设施网络中的无线接入设备，即第一设备和第二设备在基础设施网络中连接的是同一个无线接入设备。匹配可以是指相同的情况。比如第一设备所连接的无线接入设备的MAC地址为12345678，它收到的消息中的标识信息也是12345678(假设已约定包括的是MAC地址)，这个两个标识信息是相同的，这时候就是匹配的。也可以约定消息中包括的是SSID或其他标识信息。如果匹配，第一设备可以认为，它所连接的无线接入设备就是第二设备所连接的无线接入设备，第一设备与第二设备接入在同一个无线接入设备。
203、第一设备根据第二设备在基础设施网络中的地址信息，通过与第二设备连接的同一个无线接入设备与第二设备进行通信。
上述发送的信息中可以包括第一设备在基础设施网络中的地址信息，该地址信息可以是第一设备的MAC地址，也可以是第一设备的IP地址，还可以是第一设备的其他设备标识，如设备名称等；
第一设备通过所述与第二设备在基础网络中连接的同一个无线接入设备跟第二网络发送信息，双方可以用它们在基础设施网络中的地址。双方所用的它们在基础设施网络中的地址，可以是它们的MAC地址，也可以是它们的IP地址，还可以是它们的其他设备标识，如设备名称等。
当步骤202中第一设备确定自身已连接的无线接入设备的标识信息与上述第二设备在基础设施网络中连接的无线接入设备的标识信息匹配时，第一设备 即可以根据第二设备在基础设施网络中的地址信息，通过上述无线接入设备向第二设备发送信息，在某些实施例中，发送信息可以是第一设备根据第二设备在基础设施网络中的地址信息，通过基础设施网络中的无线接入设备向所述第二设备直接发送数据，例如，第一设备、第二设备在P2P网络中通信时，是第一设备向第二设备发送视频数据，此时，第一设备确定自身已连接的无线接入设备的标识信息与第二设备在基础设施网络中连接的无线接入设备的标识信息匹配时，可以根据第二设备在基础设施网络中的地址信息，通过自身已连接的无线接入设备向第二设备继续发送视频数据。
本实施例中，第一设备在与第二设备通过P2P网络进行通信时，可以接收第二设备通过P2P网络发送的消息，当第一设备确定自身已连接基础设施网络中的无线接入设备时，可以使用无线接入设备在基础设施网络中与第二设备进行通信，由于第一设备在使用P2P网络通信的过程中，可以使用基础设施网络进行通信，有效缓解了使用P2P网络时网络质量高低起伏变化的情况，保障了通信质量，用户体验佳。
二、当第一设备连接的无线接入设备与第二设备在基础设施网络中连接的无线接入设备为同一个无线接入设备时，具体为：
当第一设备确定自身已连接的无线接入设备的标识信息与第二设备在基础设施网络中连接的无线接入设备的标识信息不匹配后，第一设备接入第二设备在基础设施网络中连接的无线接入设备时。

以Wi-Fi网络环境下为例，即基础设施网络为Wi-Fi基础设施网络，P2P网络为Wi-Fi P2P网络，在Wi-Fi的网络环境下，第一设备、第二设备均可以为支持Wi-Fi的终端设备，如第一设备可以为一个支持Wi-Fi的终端设备，比如支持Wi-Fi的手机；第二设备可以为一个支持Wi-Fi的终端设备，比如支持Wi-Fi的电视机。
在Wi-Fi的网络环境下，通过Wi-Fi P2P网络发送消息，是指第一设备和第二设备已经基于P2P协议建立起了Wi-Fi P2P通信，比如基于Wi-Fi Direct，协商出一个群主设备(GO，Group Owner)，一个群成员设备(Client)，群成员设备跟群主设备关联，协商密钥等，最终建立了Wi-Fi P2P连接，然后基于这个 Wi-Fi P2P连接，一个设备给另一个设备发送消息；或者第一设备和第二设备都加入了NAN网络，基于NAN协议的机制进行通信，如收发NAN的同步信标帧、发现信标帧或服务发现帧等。

图4到图6所示的实施例中，具体描述了第一设备根据第二设备在基础设施网络中的地址信息，通过已连接的无线接入设备与第二设备进行通信的多种实现方式，可以理解的是，在实际应用中，还可以有其他实现方式，此处不作具体限定。
图4到图6所示的实施例描述了第一设备根据第二设备在基础设施网络中的地址信息，通过已连接的无线接入设备与第二设备进行通信的具体实现方式，使实现方式更加灵活。
在实际应用中，在图1至图6所示实施例的基础上，可以在第一设备根据第二设备在基础设施网络中的地址信息，通过已连接的无线接入设备与第二设备进行通信之前，对第一设备和第二设备进行一下认证，此时第一设备接收第二设备通过P2P网络发送的第一消息中还可以包括一认证数据，该认证数据用于第一设备与第二设备之间的认证。认证的作用，是为了让第一设备和第二设备在基础设施网络中通信时，确定通信的对方就是它们在P2P网络中通信的对方，这样可以避免可能存在的安全问题，提高安全性。
具体认证过程，可以是如下方式：
1、第一消息中还包括第一认证数据；这个第一认证数据便成为第一设备和第二设备都知道的一个共享信息，它们在基础设施网络中确定对方确实持有这个共享信息，便可认证对方就是在P2P网络中通信的对方。
当第一设备确定自身已连接的无线接入设备的标识信息与无线接入设备的标识信息匹配后，在第一设备根据第二设备在基础设施网络中的地址信息，通过无线接入设备向第二设备发送信息之前：
具体可以为，第一设备通过无线接入设备向第二设备发送第一认证执行数据，第一认证执行数据是第一设备根据第一认证数据加工后的数据，第二设备根据所述第一认证数据和第一认证执行数据对第一设备进行认证，即判断接收到的第一认证执行数据与第一认证数据是否匹配，在匹配时即认证成功，即认证第一设备确实就是第二设备在P2P网络中通信的对方设备；或者，反过来也 一样，第二设备通过无线接入设备向第一设备发送第二认证执行数据，第二认证执行数据是第二设备根据第一认证数据加工后的数据，第一设备根据所述第一认证数据和第二认证执行数据对第二设备进行认证，即判断接收到的第二认证执行数据与第一认证数据是否匹配，在匹配时，即认证成功，即认证第二设备确实就是第一设备在P2P网络中通信的对方设备。例如：当第一设备为STA1，第二设备为STA2，无线接入设备为AP时，STA1在P2P网络中收到STA2发送的PreShareInfo1，STA1在通过AP向STA2发送PreShareInfo1加工后的信息(即PreShareInfo11)，STA2可根据PreShareInfo1和PreShareInfo11是否匹配来认证STA1，或者，反过来也一样，STA2通过AP向STA1发送PreShareInfo1加工后的信息(即PreShareInfo12)，STA1可根据PreShareInfo1和PreShareInfo12是否匹配来认证STA2。
2、第一消息中还包括第二认证数据；
当第一设备确定自身已连接的无线接入设备的标识信息与无线接入设备的标识信息匹配后，在第一设备根据第二设备在基础设施网络中的地址信息，通过无线接入设备向第二设备发送信息之前：
第一设备通过P2P网络或者通过无线接入设备向第二设备发送第三认证数据，这个第二认证数据和第三认证数据便成为第一设备和第二设备都知道的共享信息，它们在基础设施网络中确定对方确实持有这个共享信息，便可认证对方就是在P2P网络中通信的对方。具体可以为，第一设备通过无线接入设备向第二设备发送第三认证执行数据，该第三认证执行数据是根据共享的第二认证数据和第三认证数据(即共享信息)加工后的数据，第二设备即可根据第三认证执行数据和共享的第二认证数据、第三认证数据对第一设备进行认证，即判断接收到的第三认证执行数据与共享的第二认证数据、第三认证数据是否匹配，在匹配时即认证成功；或者，反过来也一样，第二设备通过无线接入设备向第一设备发送第四认证执行数据，该第四认证执行数据是根据共享的第二认证数据和第三认证数据(即共享信息)加工后的数据，第一设备即可根据第四认证执行数据和共享的第二认证数据、第三认证数据对第二设备进行认证，即判断接收到的第四认证执行数据与共享的第二认证数据、第三认证数据是否匹配，在匹配时即认证成功。例如：当第一设备为STA1，第二设备为STA2，无线接入设备为AP时，STA1在P2P网络中收到STA2发送的PreShareInfo1后，STA1 可以通过P2P网络或者通过AP向STA2发送PreShareInfo2，然后STA1再通过AP向STA2发送PreShareInfo1+PreShareInfo2加工后的信息(即PreShareInfo11)，STA2由此可根据PreShareInfo11与PreShareInfo1+PreShareInfo2是否匹配来认证STA1的，或者，反过来也一样，STA2通过AP向STA1发送PreShareInfo1+PreShareInfo2加工后的信息(即PreShareInfo12)，STA1由此可根据PreShareInfo12与PreShareInfo1+PreShareInfo2是否匹配来认证STA2的。
上面几个例子中所述的把共享信息加工成认证执行数据的加工方法，是第一设备和第二设备都知道的一个算法，该算法可以在通信协议中进行规定。上面几个例子中所述的判断认证数据之间是否匹配的判断方法，也是第一设备和第二设备都知道的一个算法，该算法可以在通信协议中进行规定。判断是否匹配，可以是把自己持有的共享认证数据进行共知的加工成认证执行数据的方法进行加工，看加工后的数据跟接收到的认证执行数据是否相同，若相同，则认证成功。如第二设备把自己持有的共享信息即第一认证数据加工成一个数据(假设为数据A)，接收到第一设备发送的第一认证执行数据后，把自己加工得到的数据A跟接收到的第一认证执行数据进行比较，若相同，则认证成功。
需要说明的是，仅以上述几种认证方法为例介绍在当第一设备确定自身已连接的无线接入设备的标识信息与无线接入设备的标识信息匹配后，在第一设备根据第二设备在基础设施网络中的地址信息，通过无线接入设备向第二设备发送信息之前，第一设备和第二设备之间的认证过程，在实际应用过程中，也可能是其他认证过程，此处不作具体限定。
