请参阅图1，为本申请实施例提供的一种网络架构图。该网络架构可以应用于一般的直连通信场景中，如图1所示，该网络架构中可以包括第一终端10、第二终端20。
其中，第一终端10可以与第二终端20间建立直连通信连接。该直连通信连接是指该第一终端10和第二终端20之间直接通信而不借助于第三方设备，如图1所示。第一终端10与第二终端20间建立直连通信连接的方式可以包括：第一终端10与第二终端20间基于第二传输方式建立第二直连通信连接，并可以在该第二直连通信连接上交互第一传输方式的连接信息。该第一终端10与该第二终端20间可以基于该连接信息建立基于第一传输方式的第一直连通信连接。其中，第二直连通信连接在进行数据交互时的能耗值小于第一直连通信连接在进行数据交互时的能耗值，或者第二直连通信连接在进行数据交互时的能耗值小于第一终端10与第二终端20间交互该第一传输方式的连接信息时的能耗值。
其中，第二传输方式建立的第二直连通信连接包括但不限于蓝牙连接、射频连接，如近场通信(Near Field communication，NFC)连接、超声波连接、电磁波连接，如红外线连接。第一传输方式建立的第一直连通信连接包括但不限于无线保真(Wireless Fidelity，Wi-Fi)通信连接。
在一个实施例中，在建立第一直连通信连接时，可以先建立第二直连通信连接，例如，可以先在该第一终端10与第二终端20间通过蓝牙建立蓝牙连接，可以在该蓝牙连接上交互Wi-Fi的连接信息，如Wi-Fi热点的用户名和密码。该第一终端10与该第二终端20间可以基于该连接信息建立基于Wi-Fi热点的第一直连通信连接。第一终端10可以在建立第二直连通信连接后，主动开启第一终端20的Wi-Fi热点功能，以便于建立与第二终端20之间的第一直连通信连接，也可以通过第二直连通信连接触发第二终端20开启Wi-Fi热点功能，以便于第一终端101接入到第二终端102完成第一直连通信连接的建立。
在一个实施例中，第一终端10的用户在需要向第二终端102传输数据时，可以在该第一终端10上配置管理第一终端10上的传输模式(该传输模式，对应于至少一种数据传输方式)的直连通信按钮，在点击该按钮开启了第一终端10的直连通信模式之后，该第一终端10便可以自动开启蓝牙对应的第二传输功能以及Wi-Fi对应的第一传输功能。同样，该第二终端20的用户也可以开启第二终端20的直连通信按钮，并自动开启蓝牙对应的第二传输功能以及Wi-Fi对应的第一传输功能。然后，第一终端10的用户可以在第一终端10通过蓝牙扫描到的至少一个终端中确定出第二终端20，该第一终端10与第二终端20建立该蓝牙连接。
在一个实施例中，在需要建立第一直连通信连接时，该第一终端10也可以首先检测自身的电量值，如果该电量值大于电量预设百分比(例如90％)，那么该第一终端10也可以直接建立基于Wi-Fi热点的第一直连通信连接。如果该电量值小于或者等于该电量预设百分比(例如20％)，那么该第一终端10可以首先建立该基于蓝牙的第二直连通信连接，再在蓝牙连接的基础上建立Wi-Fi连接，以完成第一直连通信连接的建立。
可见，本申请实施例可以通过蓝牙连接(即第二直连通信连接)交互用于建立Wi-Fi连接(即第一直连通信连接)的连接信息，连接信息例如可以是作为Wi-Fi热点的终端的用户名和接入密码，再根据该连接信息建立Wi-Fi连接(即第一直连通信连接)，在一定程度上节约了终端能耗，并且该Wi-Fi连接(即第一直连通信连接)可以保证较快的传输速度，同时也提高了终端在传输数据时的传输效率。
在一个实施例中，在需要建立第一直连通信连接时，还可以先在第一终端10中开启Wi-Fi热点，并通过二维码的方式携带该Wi-Fi热点的用户名和密码，第二终端20可以扫描该二维码，进而直接得到第一终端10的Wi-Fi热点的用户名和密码，接入到第一终端10建立两者之间的第一直连通信连接。或者第二终端20开启Wi-Fi热点，并通过二维码的方式携带该Wi-Fi热点的用户名和密码，第一终端10可以扫描该二维码，进而直接得到第二终端20的Wi-Fi热点的用户名和密码，接入到第二终端20建立两者之间的第一直连通信连接。
下面将在图1所描述的实施例1的基础上，结合本申请以包括三个终端的网络架构进行简要说明。请参阅图2，图2为本申请实施例提供的一种网络架构图。如图2所示，该网络架构中可以包括第一终 端10、第二终端20、第三终端30。
该第一终端10、第二终端20、第三终端30可以构成一个直连通信集群，该直连通信集群中的各个终端可以通过互相建立的直连通信连接，以交互数据。该直连通信集群中，还可以包括其它终端，本申请实施例仅为展现的其中一个简单的网络架构。
除此之外，第一终端10还可以与多个终端(除第二终端20、第三终端30)、建立直连通信连接以形成子直连通信集群。相应地，第二终端20、第三终端30也可以像第一终端10一样，形成各自的子直连通信集群。第一终端10、第二终端20以及第三终端30均可以根据需要通过直连通信连接将数据发送至对应子直连通信集群中。
其中，本申请实施例提及的直连通信连接为终端间不借助第三方设备建立的无线通信连接，包括但不限于终端之间的Wi-Fi连接、蓝牙连接、射频连接，如NFC连接、红外线连接、超声波连接等无线通信连接。其中，终端之间的Wi-Fi连接是指两个终端中至少有一个终端开启了Wi-Fi热点功能，另一终端直接接入到该建立了Wi-Fi热点的终端，建立直连通信连接。
在一个实施例中，第一终端10、第二终端20、第三终端30互相之间可以通过建立的不同的直连通信连接，如第一直连通信连接、第二直连通信连接实现数据的并发。
在一个实施例中，该第一直连通信连接可以为能够快速传输视频、图片等数据量大于或等于预置阈值(或者大于或等于预置的数据量阈值)的数据的通信连接，包括但不限于Wi-Fi连接等无线通信连接。第二直连通信连接为功耗小于预设阈值，且能够传输数据量小于预置阈值(或者小于预置的数据量阈值)的数据的通信连接，包括但不限于，如蓝牙连接、射频连接、红外线连接等无线通信连接。
在该第一直连通信连接是针对数据量大于预置阈值(或者大于或等于预置的数据量阈值)的待传输数据中的某部分数据(包括但不限于某一类文件数据，如第二类文件数据)时，该第一终端10、第二终端20、第三终端30可以通过在上述三个终端间建立的第一直连通信连接传输该待传输数据中的某部分数据(包括但不限于某一类文件数据，如第二类文件数据)。
或者，在该第二直连通信连接是针对数据量小于预置阈值(或者小于预置的数据量阈值)的待传输数据中的另一部分数据(包括但不限于另一类文件数据，如第一类文件数据)时，该第一终端10、第二终端20、第三终端30可以通过在上述三个终端间建立的第二直连通信连接传输该待传输数据中的另一部分数据(包括但不限于另一类文件数据，如第一类文件数据)。
在该第一直连通信连接是针对数据量大于或等于预置阈值(或者大于或等于预置的数据量阈值)的待传输数据时，该第一终端10、第二终端20、第三终端30可以通过在上述三个终端间建立的第一直连通信连接传输该待传输数据。例如，若第一终端10确定出该待传输数据的数据量为20M，预置的数据量阈值为5M。第一终端10可以确定该待传输数据的数据量大于预置的数据量阈值，则通过与该第二终端20建立的第一直连通信连接，如Wi-Fi连接，传输该待传输数据。或者，在该第一直连通信连接是针对数据量小于预置阈值(或者小于预置的数据量阈值)的待传输数据时，该第一终端10、第二终端20、第三终端30可以通过在上述三个终端间建立的第二直连通信连接传输该待传输数据。例如，若该第一终端10确定出该待传输数据的数据量为1M，预置的数据量阈值为5M，第一终端10可以确定该待传输数据的数据量小于预置的数据量阈值，则通过与该第二终端20建立的第二直连通信连接，如蓝牙连接，传输该待传输数据。
在一个实施例中，在某一终端将数据发送至另外一个终端时，该另外一个终端在接收到该数据后，可以将该数据作为该另外一个终端的待传输数据。其中，该数据可以是某一终端的待传输数据、待传输数据中部分数据，如某一类数据(包括但不限于某一类文件数据)。换句话说，也可以理解为某一终端的已传输数据可以作为另外一个终端的待传输数据。
在一个实施例中，若某一终端(如第一终端10)向另外一个终端(如第二终端20)传输完待传输数据中的某一类数据后，如第一类文件数据，则可以发送指示信息至该另外一个终端(如第二终端20)或者目标终端(如第三终端30)，该指示信息可以用于指示该另外一个终端(如第二终端20)和目标终端(如第三终端30)建立第二直连通信连接，并在该第二直连通信连接上传输该第一类文件数据。传输完的第一类文件数据可以作为某一终端对另外一个终端的已传输数据。
在一个实施例中，若某一终端(如第一终端10)对另外一个终端(如第二终端20)的已传输数据在待传输数据中的比例超过预置的比例阈值后，如超过80％，则可以发送通知消息至该另外一个终端(如第二终端20)或者目标终端(如第三终端30)，该通知消息可以用于通知该另外一个终端(如第二终端20)作为发送端，并通过与目标终端(如第三终端30)建立的直连通信连接，传输该已传输数据。
在一些实施例中，直连通信集群中各终端间还可以通过第二直连通信连接交互一些请求/消息/指令/信息。例如，上述的通知消息、指示信息。
该第一终端10、第二终端20、第三终端30可以根据各自的数据收发的需求，作为发送端和/或接收端来传输数据。
在第一终端10需要向直连通信集群中的各个终端传输数据时，可以作为发送端以通过与该直连通信集群中的各个终端建立的直连通信连接，向各个终端传输数据。该直连通信集群中的各个终端可以作为接收端，通过与第一终端10建立的直连通信连接(例如第一直连通信连接或第二直连通信连接)接收由第一终端10发送的数据。
第一终端10可以通过与第二终端20间建立的直连通信连接发送数据至第二终端20。第二终端20可以通过与第一终端10建立的直连通信连接接收到该第一终端10发送的数据。其中，第一终端20还可以通过与第三终端30间建立的直连通信连接发送数据至第三终端30。第三终端30可以通过与第一终端10建立的直连通信连接接收到该第一终端10发送的数据。
在一个实施例中，该第一终端10可以在需要向直连通信集群中的各个终端传输数据时，将直连通信模式配置为发送模式，以向该直连通信集群中各个处于接收模式的终端发送数据。相应地，该第二终端20、该第三终端30可以分别将直连通信模式配置为接收模式，以针对性的接收处于发送模式的终端发送的数据，可以更好地根据各终端的收发需求来选择发送和接收数据。
其中，在第一终端10被配置为发送模式，且该第二终端20被配置为接收模式时，第一终端10可以通过与第二终端20间建立的直连通信连接发送数据至第二终端20。第二终端20可以通过与第一终端10建立的直连通信连接接收到该第一终端10发送的数据。
在第一终端10在被配置为发送模式，且该第三终端30被配置为接收模式时，第一终端10也可以通过与第三终端30建立的直连通信连接发送数据至第三终端30。第三终端30可以通过与第一终端10建立的直连通信连接接收到该第一终端10发送的数据。
该第一终端10除了与该直连通信集群中的各个终端直接建立直连通信连接以发送数据之外，还可以通过该直连通信集群中的其它终端向直连通信集群中的目标终端发送数据。
在一个实施例中，该目标终端可以为第一终端10确定出的该直连通信集群中需要接收该待传输数据的初始终端中，与第一终端10间的信号强度小于预置信号强度阈值的初始终端。或者，该目标终端也可以是该直连通信集群中未接收到第一终端10发送的数据的终端。或者，该目标终端还可以是该直连通信集群中与该第一终端10的数据传输过程中断的终端。或者，该目标终端还可以是第一终端10根据获取该直连通信集群中的接收端的设备信息选取的终端。在一个实施例中，该目标终端可以是接收端，还可以是被配置为接收模式的终端。
对应到本网络架构中，该第一终端10除了直接与该第三终端30建立直连通信连接以发送数据之外，还可以通过第二终端20，以发送数据至目标终端，如第三终端30。相应地，第一终端10除了与该第二终端20建立直连通信连接以发送数据之外，还可以通过第三终端30以发送数据至目标终端，该目标终端例如为第二终端20。
下面将以第一终端10通过第二终端20发送数据至作为目标终端的第三终端30为例进行进一步说明。
若第一终端10通过与第二终端20建立的直连通信连接，发送数据至第二终端20。第二终端30可以通过与第三终端30建立的直连通信连接以将该第一终端10发送的数据发送至第三终端30。可选地，该第二终端20可以被配置为中继模式，以便可以接收第一终端10发送的数据，并将接收到的该第一终端10发送的数据转发至第三终端30。
在一个实施例中，该第二终端20可以由第一终端10根据该直连通信集群中的各个终端的性能信息确定的。
其中，该第二终端20可以是第一终端10根据该直连通信集群中的各个终端的性能信息确定出的性能状态较佳的终端。如，该第二终端20为第一终端10确定出的该直连通信集群中剩余电量最多的终端，或者剩余电量超过预置的电量阈值的终端。
发送端在和多个接收端形成直连通信集群后，各个接收端可以将当前本机的性能信息，如存储空间、剩余电量、剩余内存、传输速度等信息上报至发送端，以便该发送端可以根据该上报的性能信息确定出性能状态最好的某个终端以发送数据至目标终端。
在一个实施例中，该直连通信集群中的各个终端在检测到第一终端10用于获取性能信息的请求时，可以将该直连通信集群中的各个终端性能信息分别通过与该第一终端10建立的直连通信连接发送至该第一终端10。
在一个实施例中，该第二终端20还可以是在确定该第一终端10的性能信息满足预置切换条件，如性能信息小于对应预置的阈值时，该第一终端10根据该直连通信集群中的各个终端的性能信息确定出的终端。
在一个实施例中，该第二终端20还可以是在确定该第一终端10的性能信息小于对应预置的阈值时，该第一终端10根据该直连通信集群中的各个终端的性能信息确定出的终端，如性能状态较佳的终端。其中，第一终端10的性能信息包括但不限于第一终端10的存储空间、剩余电量、剩余内存、传输速度等信息。
在一个实施例中，该第一终端10的性能信息小于对应预置的阈值可以通过如下方式确定：在该第一终端10的性能信息包括剩余电量时，判断该剩余电量是否小于预置的第一电量阈值；在该第一终端10的性能信息包括传输速度时，判断该传输速度是否小于预置的第一速度阈值；若该剩余电量小于该预置的第一电量阈值和/或该传输速度小于该预置的第一速度阈值，则确定该第一终端10的性能信息小于对应预置的阈值。
其中，除了可以利用第一终端10的性能信息中的各个信息以单独判断该第一终端10的性能信息是否小于对应预置的阈值外，还可以将第一终端10的性能信息中的剩余电量、剩余内存、存储空间、传输速度等信息以递进或者并列的形式组合起来判断第一终端10的性能信息是否小于对应预置的阈值。
在一个实施例中，该第一终端10的性能信息小于对应预置的阈值还可以通过如下方式确定：在该第一终端10的性能信息包括剩余电量时，判断该剩余电量是否小于预置的第一电量阈值；若小于，在该第一终端10的性能信息包括传输速度时，判断该传输速度是否小于预置的第一速度阈值；若小于，若该剩余电量小于该预置的第一电量阈值和/或该传输速度小于该预置的第一速度阈值，则确定该第一终10端的性能信息小于对应预置的阈值。
在一个实施例中，该第一终端10根据该直连通信集群中的各个终端的性能信息确定出第二终端20可以包括：判断该直连通信集群中各个终端的剩余电量是否超过预置的电量阈值；判断该直连通信集群中各个终端的剩余内存是否超过预置的剩余内存阈值；确定该各个终端中剩余电量超过预置的电量阈值，和/或确定该各个终端中剩余内存超过预剩余内存阈值的终端为第二终端。在一个实施例中，该电量阈值、速度阈值对应可以为第二电量阈值、第二速度阈值。
其中，除了可以利用直连通信集群中各个终端的性能信息中的各个信息以单独判断以确定出第二终端20外，还可以将直连通信集群中各个终端的性能信息中的各个信息以递进或者并列的形式组合起来确定出第二终端20。
在一个实施例中，该第一终端10根据该直连通信集群中的各个终端的性能信息确定出第二终端20可以包括：判断该直连通信集群中各个终端的性能信息中的剩余电量是否大于或者等于预置的第二电量阈值；在确定该各个终端中包括剩余电量大于或者等于该预置的第二电量阈值的多个终端时，判断该多个终端的性能信息中的传输速度是否大于或者等于预置的第二速度阈值；选取该多个终端中传输速度大于或者等于该预置的第二速度阈值的终端作为第二终端。
在一个实施例中，该各个终端的性能信息除了可以包括前述的剩余电量、剩余内存、存储空间、传 输速度，还可以包括已接收数据的数据量。
在一个实施例中，该第一终端10根据该直连通信集群中的各个终端的性能信息确定出第二终端20还可以包括：判断该直连通信集群中各个终端的性能信息中的已接收数据的数据量是否大于或等于预置的数据接收阈值；在确定该各个终端中包括已接收数据的数据量大于或等于预置的数据接收阈值的多个终端时，判断该多个终端的性能信息中的传输速度是否大于或者等于预置的第二速度阈值；选取该多个终端中传输速度大于或者等于该预置的第二速度阈值的终端作为第二终端。
在一个实施例中，该第二终端20还可以是第一终端10根据获取的直连通信集群中各个终端的设备信息确定的。
处于发送模式的第一终端10可以通过与处于中继模式的第二终端20建立的直连通信连接，发送数据至处于中继模式的第二终端20。处于中继模式的第二终端30可以通过与处于接收模式的第三终端30建立的直连通信连接，将该处于接收模式的第一终端10发送的数据发送至处于接收模式的第三终端30。
在一个实施例中，第二终端10可以通过与第三终端30间的第二直连通信连接，获取第三终端30的设备信息；第二终端20可以将第二终端20的设备信息、第三终端30的设备信息发送至第一终端10。第一终端10在接收到第二终端20发送的设备信息后，可以将该第三终端30的设备信息确定为发送数据的目标终端。
以手机A包括接收模式、发送模式、中继模式为例。用户可以通过点击中继模式选项或者图标，将手机A的直连通信模式设置为中继模式。处于中继模式的手机A可以获取其它处于接收模式的手机B的设备信息，并且手机A可以获取到处于发送模式的手机C的设备信息，从而可以将该处于接收模式的手机B的设备信息发送至该处于发送模式的手机C。
该第二终端20可以在接收到第一终端10的转发请求时，通过第一直连通信连接获取发起终端10的发送的数据，并可以根据该转发请求中指示的传输路径转发该第一终端发送的数据；该转发请求指示的传输路径可以为通过第二终端20将第一终端10发送的数据发送至第三终端30。该转发请求可以包括第三终端的设备信息。该传输路径可以是第一终端10根据获取的设备信息确定的。
在一个实施例中，该第二终端20可以在接收到第一终端10的转发请求时，通过第二直连通信连接获取发起终端10的发送的数据，并可以根据该转发请求中指示的传输路径转发该第一终端发送的数据；该转发请求指示的传输路径可以为通过第二终端20将第一终端10发送的数据发送至第三终端30。该转发请求可以包括第三终端的设备信息。该传输路径可以是第一终端10根据获取的设备信息确定的。
在一个实施例中，如果该转发请求中指示的传输路径所指示的下一节点是第二终端20，则第一终端10与该第二终端20可以建立第一直连通信连接以传输数据；如果该转发请求中指示的传输路径所指示的下一节点是该直连通信集群中其它终端，则第一终端10与该其它终端建立第一直连通信连接以传输数据。该其它终端可以为其它接收端。
该第一终端10可以显示一个用户界面，该用户界面可以用于显示获取的设备信息。第一终端10可以接收针对设备信息的选择操作，并根据该选择操作确定出传输路径。例如，第一终端10在需要向第三终端30传输数据1时，可以在选取该第三终端30以作为发送数据1的目标终端后，再选取第二终端20以确定传输路径为通过第二终端20进行数据转发。
在一个实施例中，该设备信息可以包括对应终端的标识，如媒体访问控制(Media Access Control，MAC)地址、互联网协议(Internet Protocol，IP)地址、名称、端口号等。在一个实施例中，该设备信息可以包括对应终端的标识、以及对应终端所处的直连通信模式。
该第二终端20还可以是被配置为接收模式的终端，在接收到第一终端10发送的数据后，可以通过将第二终端20的直连通信模式配置为发送模式，使得该第二终端20可以切换为发送端以发送数据到处于接收模式的第三终端30。在一个实施例中，若第三终端30一直用于接收数据，则可以将该第三终端30的直连通信模式配置为接收模式。
在一个实施例中，直连通信集群中的各个终端设置有直连通信模式，该直连通信模式可以为发送模式、接收模式、中继模式。若终端被配置为发送模式，则该终端可以为用于发送数据的发送端，若该终端被配置为中继模式，那么该终端可以用于转发数据。若终端被配置为接收模式，则该终端可以为用于 接收数据的接收端。
在一个实施例中，各个终端可以配置有一个直连通信按钮，点击该直连通信按钮后，可以进行直连通信模式的选择。
当该直连通信集群中的某个终端开启中继模式后，某个终端可以将周围扫描到的处于接收模式的终端的设备信息，发送到周围处于发送模式的终端。通常在某个终端的传输距离受限，可以通过处于中继模式的终端来转发数据以扩大传输距离。除此之外，若某个终端的传输距离未受限，则也可以通过处于中继模式的终端来转发数据来扩展数据传输方式。
在一个实施例中，发送端可以管理自己扫描到的接收端的设备信息，以及中继设备发送过来的接收端的设备信息。该接收端可以为处于接收模式的终端。中继终端可以为处于中继模式的终端。该发送端可以为处于发送模式的终端。
在一个实施例中，若用户在发送端选择一个接收端作为目标终端后(可以是根据获取的接收端的设备信息选取的)，则发送端可以根据该接收端反馈上来的路径将数据先传输至下一个的中继终端，在由该中继终端传输至目标终端。或者，在该用户选择一个接收端作为目标终端后，用户可以再选取一个以转发数据的中继终端，再由该中继终端将数据传输至目标终端。
该直连通信集群中各个终端根据设置的直连通信模式不同，可以进行多个直连通信模式的切换，以便基于设置的不同直连通信模式，来使各个终端提供不同功能。并且可以在终端间距离发生变化，距离较远、终端性能较差等原因导致不能继续传输任务或者不想继续数据传输时，通过将终端作为中继终端的方式，可以扩展数据传输距离，增加组网的灵活性。
在一个实施例中，该第一终端10在被配置为中继模式时，可以基本实现第二终端20处于中继模式时所实现的所有功能。该第二终端20在被配置为发送模式时，可以基本实现第一终端10处于发送模式时所实现的所有功能。

在一个实施例中，第二终端20与第三终端30之间的用于传输数据的直连通信连接可以通过第一终端10发送连接请求的形式触发建立。
在一个实施例中，该连接请求可以由第一终端10发送至目标终端，如第三终端30。其中，该连接请求可以包括第二终端20的设备信息。或者，该连接请求还可以由第一终端10发送至第二终端20。其中，该连接请求可以包括目标终端，如第三终端30的设备信息。
在一个实施例中，根据连接请求所触发建立的直连通信连接的不同，该连接请求还可以包括第一连接请求，第二连接请求。
在一个实施例中，第一终端10可以确定发送的数据的数据量；并在该数据的数据量大于或等于预置阈值(或者大于或等于预置的数据量阈值)时，发送第一连接请求至第二终端20或者第三终端30，该第一连接请求10用于触发建立该第二终端20与第三终端30间的第一直连通信连接；在该数据的数据量小于预置阈值(或者小于预置的数据量阈值)时，则发送第二连接请求至第二终端20或者第三终端30，该第二连接请求用于触发建立该第二终端20与第三终端30之间的第二直连通信连接，从而实现根据第一终端10传输的数据的数据量的不同，触发与第二终端20建立不同的直连通信连接以进行数据的传输，提高了数据传输效率。其中，该第一连接请求、第二连接请求可以通过第一终端10与第二终端间建立的第二直连通信连接发送至第二终端20，也可以通过第一终端10与第三终端30建立的第二直连通信连接发送至第三终端30。

本申请实施例中，该第一终端的性能信息包括但不限于第一终端的存储空间、剩余电量、剩余内存、传输速度等信息。该待传输数据可以为第一终端选取的将要传输的音视频文件、图片、文档等数据。
需要说明的是，第一终端可以与直连通信集群中的各个终端建立直连通信连接。该直连通信连接可以为第一直连通信连接和/或第二直连通信连接。
S202、若确定所述第一终端的性能信息小于对应预置的阈值，则根据所述直连通信集群中各个终端的性能信息确定出第二终端。
本申请实施例中，该各个终端的性能信息包括但不限于各个终端的存储空间、剩余电量、剩余内存、传输速度等信息。可选地，在该第一终端的性能信息包括剩余电量时，判断该剩余电量是否小于预置的第一电量阈值；在该第一终端的性能信息包括传输速度时，判断该传输速度是否小于预置的第一速度阈值；若该剩余电量小于该预置的第一电量阈值和/或该传输速度小于该预置的第一速度阈值，则确定该第一终端的性能信息满足预置的切换条件。举例来说，假设第一终端的预置的第一电量阈值为30％、第一速度阈值为0.5M/s。在该第一终端当前的剩余电量为60％，可以确定传输速度为1M/s，则可以确定第一终端的性能信息不小于对应预置的阈值。若该终端当前的剩余电量低于60％，和/或当前的传输速度小于1M/s，则可以确定该第一终端的性能信息小于对应预置的阈值。
本申请实施例可以在该第一终端性能状态不佳时，及时地确定出第二终端以传输待传输数据，从而可以保障数据传输的连续性，提高了数据传输效率，避免了第一终端因性能不佳导致数据传输的中断，需再建立连接以重传数据。其中，该传输速度指的是数据传输速度。可选地，可以通过先发送一个探测帧以测试该传输速度。
可选地，在该第一终端的性能信息包括传输速度时，第一终端可以判断该传输速度是否小于预置的第一速度阈值；若小于，在该第一终端的性能信息包括剩余电量时，第一终端可以判断该剩余电量是否小于预置的第一电量阈值；若小于，则第一终端可以确定该第一终端的性能信息小于对应预置的阈值。
举例来说，假设第一终端的预置的第一电量阈值为30％、第一速度阈值为0.5M/s。在该第一终端当前的传输速度为0.3M/s时，可以确定该传输速度小于0.5M/s。若该第一终端当前的剩余电量为20％，则可以进一步确定剩余电量小于30％。因此，可以确定第一终端的性能信息小于对应预置的阈值。
可选地，在该第一终端的性能信息包括存储空间时，第一终端可以判断该存储空间是否小于预置的第一存储空间阈值；若小于，在该第一终端的性能信息包括剩余内存时，第一终端可以判断该剩余内存是否小于预置的第一剩余内存阈值；若小于，则第一终端可以确定该第一终端的性能信息小于对应预置的阈值。
可选地，在该第一终端的性能信息包括传输速度时，第一终端可以判断该传输速度是否小于预置的第一速度阈值；若小于，在该第一终端的性能信息包括剩余内存时，第一终端可以判断该剩余内存是否小于预置的第一剩余内存阈值；若小于，则第一终端可以确定该第一终端的性能信息小于对应预置的阈值。
在步骤S302中，第一终端可以根据该直连通信集群中各个终端的性能信息确定出第二终端，以便第一终端将数据传输任务转交给第二终端，第二终端可以继续第一终端的数据传输任务，从而保障数据传输的时效性。
其中，该第一终端可以通过与该直连通信集群中各个终端建立的第二直连通信连接，来获取直连通信集群中各个终端的性能信息。本申请实施例中，该第二直连通信连接包括但不限于射频连接、蓝牙连接、超声波连接等无线通信连接。该第一直连通信连接可以为Wi-Fi连接等无线通信连接。
举例来说，如图4所示，该直连通信集群中包括终端400、终端401、终端402、终端403、终端404。在该直连通信集群中，若第一终端为终端402，则终端402可以通过第二直连通信连接，如蓝牙连接，获取到终端400的剩余电量、终端401的剩余电量、终端403的剩余电量、终端404的剩余电量。
其中，该第一终端可以通过比较分析该直连通信集群中的各个终端的性能信息以确定出性能状态较佳或最佳的终端作为第二终端。可选地，若获取的性能信息为剩余电量，则第一终端可以通过比较分析该通信集群中各个终端的剩余电量，从而可以确定出剩余电量较多或者最多的终端为第二终端。可选地，若获取的性能信息为剩余内存，则第一终端可以通过比较分析该通信集群中各个终端的剩余内存，从而可以确定出剩余内存较多或者最多的终端为第二终端。可选地，若获取的性能信息为传输速度，则第一终端可以通过比较分析该通信集群中各个终端的数据的传输速度，从而可以确定出传输速度较快或者最快的终端为第二终端。可选地，第一终端还可以结合各个终端的存储空间、剩余电量、剩余内存、传输速度等信息中的两种或者多种信息来确定出第二终端。
进一步可选地，第一终端判断该直连通信集群中各个终端的性能信息中的剩余电量是否大于或者等于预置的第二电量阈值；在确定该各个终端中包括剩余电量大于或者等于该预置的第二电量阈值的多个终端时，判断该多个终端的性能信息中的传输速度是否大于或者等于预置的第二速度阈值；选取该多个终端中传输速度大于或者等于该预置的第二速度阈值的终端作为第二终端。

进一步可选地，可以选取该多个终端中传输速度最大的终端作为第二终端。其中，该第二电量阈值可以与前述第一电量阈值相同，也可以不同。该第二速度阈值也可以与前述第一速度阈值相同，也可以不同。
需要说明的是，在确定第二终端作为发送端传输数据时，往往需要选取电量较多，传输速度较快的终端来作为第二终端。因此，根据电量以及传输速度确定出性能状态较佳或者最佳的第二终端的情况，与第一终端的性能信息低于对应预置的阈值，即与第一终端的性能状态不好的情况确定出第二终端的情况有所不同，所以第二速度阈值往往大于该第一速度阈值、第二电量阈值大于第一电量阈值。
进一步可选地，第一终端判断该直连通信集群中各个终端的性能信息中的已接收数据的数据量是否大于或等于预置的数据接收阈值；在确定该各个终端中包括已接收数据的数据量大于或等于预置的数据接收阈值的多个终端时，判断该多个终端的性能信息中的传输速度是否大于或者等于预置的第二速度阈值；选取该多个终端中传输速度大于或者等于该预置的第二速度阈值的终端作为第二终端。其中，终端可以根据确定出数据的数据量较大的终端，从而保障数据传输的完整性，并且可以通过进一步通过确定传输速度较快的终端，可以保障终端间处于较高的传输速度，能快速地传输数据。其中，若存在终端未接收到第一终端传输的数据，则已接收数据的数据量为0。
举例来说，如图4所示，该直连通信集群中包括终端400、终端401、终端402、终端403、终端404。在该直连通信集群中，若第一终端为终端402，则终端402可以通过第二直连通信连接，如蓝牙连接，获取到终端400的已接收数据的数据量以及传输速度、终端401的已接收数据的数据量以及传输速度、终端403的已接收数据的数据量以及传输速度、终端404的已接收数据的数据量以及传输速度。若预置的数据接收阈值为100M、预置的第二速度阈值为1M/s。若终端402确定出已接收数据的数据量大于或等于100M的终端有终端400以及终端401，则可以再进一步判断终端400的传输速度以及终 端401中传输速度是否大于1M/s的终端。若终端401的传输速度大于1M/s，则可以确定终端401为第二终端。
进一步可选地，可以选取该多个终端中传输速度最大的终端作为第二终端。
进一步可选地，第一终端判断该直连通信集群中各个终端的性能信息中的剩余内存是否大于或者等于预置的第二剩余内存阈值；在确定该各个终端中包括剩余内存大于或者等于该预置的第二剩余内存阈值的多个终端时，判断该多个终端的性能信息中的传输速度是否大于或者等于预置的第二速度阈值；选取该多个终端中传输速度大于或者等于该预置的第二速度阈值的终端作为第二终端。
进一步可选地，第一终端判断该直连通信集群中各个终端的性能信息中的已接收数据的数据量是否大于或等于预置的数据接收阈值；在确定该各个终端中包括已接收数据的数据量大于或等于预置的数据接收阈值的多个终端时，判断该多个终端的性能信息中的剩余内存是否大于或者等于预置的第二剩余内存阈值；选取该多个终端中剩余内存大于或者等于该预置的第二剩余内存阈值的终端作为第二终端。

S303、若确定对所述第二终端的已传输数据在所述待传输数据中的比例超过预置的比例阈值，则发送通知消息至所述第二终端或者所述直连通信集群中的目标终端。
本申请实施例中，该通知消息用于通知该第二终端作为发送端，并与该目标终端之间通过建立的直连通信连接传输该已传输数据。
可选地，该已传输数据在所述待传输数据中的比例可以为该已传输数据在该待传输数据中所占的数据量。相应地，该预置的比例阈值可以为预置的数据量的阈值。可选地，可以为该已传输数据在该待传输数据中所占的数据量的阈值。可选地，该已传输数据在所述待传输数据中的比例还可以为该已传输数据在该待传输数据中所占的百分比。相应地，该预置的比例阈值可以为预置的百分比的阈值。可选地，可以为该已传输数据在该待传输数据中所占的百分比的阈值。

举例来说，若第一终端确定出该已传输数据的数据量为10M，预置的数据量阈值为6M。第一终端可以确定该已传输数据的数据量大于预置的数据量阈值，则发送第一连接请求。该第一连接请求可以触发该第二终端与直连通信集群中的目标终端建立第一直连通信连接，如Wi-Fi连接。
