一般的电子设备的硬件结构中通常包括两个完整的基带处理模块和一个RF前端。电子设备使用两个基带处理模块和一个RF前端(该RF前端要按照时间片的划分切换频段)进行数据传输的情形被称为双频单发(Dual Band Single Concurrent，DBSC)模式，或者也可以被称为双频自适应并发(Dual Band Adaptive Concurrent，DBAC)，下面以被称为DBAC模式为例进行说明。例如，两个基带处理模块可分别支持Wi-Fi模块在2.4GHz的频段上进行工作，和在5GHz的频段上进行工作。RF前端可以选择一个频段进行工作，实现在单频段上的数据传输，如RF前端可以选择工作在2.4GHz频段上进行数据传输，或者，可以选择工作在5GHz频段上进行数据传输。由于电子设备只有一个RF前端，所以该电子设备在同一时间段内只能选择工作在一种频段上进行数据传输。该电子设备可以通过RF前端频段切换(按照时间片的划分)，换一个频段进行数据传输，通过RF前端频段切换，可以实现不同时分的双频数据传输，该种数据传输的情形被称为DBAC模式。例如，一电子设备进行数据传输的情形为DBAC模式(下文中简称为一电子设备为DBAC模式)，该电子设备在5GHz频段上进行数据传输时，可以通过RF前端的频段切换，在2.4GHz频段上进行数据传输，实现在不同时分的双频数据传输。有些电子设备的硬件结构中可以包括两个完整的基带处理模块和两个RF前端。电子设备同时使用两个基带处理模块和两个RF前端进行数据传输的情形被称为双频双发(Dual Band Dual Concurrent，DBDC)模式(下文中简称为一电子设备为DBDC模式)。两个基带处理模块分别支持Wi-Fi模块在2.4GHz的频段上进行工作，和在5GHz的频段上进行工作。两个RF前端分别选择工作在2.4GHz频段上进行数据传输和工作在5GHz频段上进行数据传输，可以实现相同时分的双频数据传输。也可以是说，一电子设备为DBDC模式，由于该电子设备有两个RF前端，所以该电子设备可以同时工作在5GHz频段上和在2.4GHz频段上进行数据传输，实现相同时分的双频数据传输。
2.4GHz频段具有穿墙能力强的特点，为保证信号稳定，市面上的单频路由器通常只支持在2.4GHz频段上进行工作，这种情况下电子设备是在2.4GHz频段上与单频路由器进行数据传输，以连接WLAN实现上网。市面上的双频路由器可以同时支持在2.4GHz频段上工作和 在5GHz频段上进行工作，这种情况下电子设备可以选择在2.4GHz频段上与双频路由器进行数据传输，也可以选择在5GHz频段上与双频路由器进行数据传输。但是由于2.4GHz频段的覆盖范围比5GHz频段的覆盖范围大，双频路由器的全部覆盖区域中，5GHz频段未覆盖的范围较大，所以在与电子设备构建的多屏协同系统中，电子设备可以在2.4GHz或5GHz频段上与双频路由器进行数据传输，以连接WLAN实现上网。
由于5GHz频段具有传输效率快的特点，建立协同连接的两个电子设备之间可以在5GHz频段上进行数据传输。
根据上述分析，所以在多屏协同系统中，建立协同的两个电子设备之间可以在5GHz频段上进行数据传输，而两个电子设备中每个电子设备可以在2.4GHz或5GHz频段上与路由器进行数据传输。
若一多屏协同系统中电子设备之间进行数据传输的频段与电子设备与路由器之间进行数据传输的频段不同，该多屏协同系统的数据传输情形被称之为异频异信道。若一多屏协同系统中电子设备之间进行数据传输的频段与电子设备分别与路由器之间进行数据传输的频段相同，该多屏协同系统的数据传输情形被称之为同频，可以包括同频同信道和同频异信道。通过切换信道，同频同信道和同频异信道之间可以相互转换。在同频同信道中进行数据传输的效率，大于在同频异信道中进行数据传输的效率。
例如，如图2所示，在多屏协同系统中建立协同的手机10与平板电脑20之间通过5GHz频段进行数据传输、手机10与路由器30之间或平板电脑20与路由器30之间通过2.4GHz频段进行数据传输，该多屏协同系统的数据传输情形被称为异频异信道。
例如，如图3所示，在多屏协同系统中建立协同的手机10与平板电脑20之间、手机10与路由器30之间和平板电脑20与路由器30之间都通过5GHz频段进行数据传输，该多屏协同系统的数据传输情形被称为同频。若手机10与平板电脑20、手机10与路由器30、平板电脑20与路由器30之间的通信信道都相同，该多屏协同系统的数据传输情形被称为同频同信道；否则，该多屏协同系统的数据传输情形被称为同频异信道。
只有一个RF前端的电子设备对应的多屏协同系统的数据传输情形为异频异信道的情况下，该电子设备需要使用DBAC模式进行数据传输。也就是说，只有一个RF前端的电子设备对应的多屏协同系统的数据传输情形为异频异信道时，该电子设备需要进入DBAC模式，通过在划分的不同时间片中不断切换RF前端的工作频段，实现与路由器的数据传输，或者实现与另一个电子设备的数据传输。电子设备为DBAC模式时，由于时间片的划分，电子设备可以包括三种状态：P2P时间片状态、频段切换状态、STA时间片状态，电子设备可以按照一定顺序在这三个状态中进行切换。其中，P2P时间片状态用于该电子设备与建立协同连接的另一电子设备进行数据传输，例如，可以通过5GHz频段进行数据传输。STA时间片状态，用于该电子设备与路由器进行数据传输，例如，可以通过2.4GHz频段进行数据传输。例如，如图4所示，电子设备从P2P时间片状态切换至STA时间片状态需要一定的切换时间，在切换过程中，电子设备处于频段切换状态，如处于频段切换1状态。电子设备从STA时间片状态切换至P2P时间片状态也需要一定的切换时间。在切换过程中，电子设备同样处于频段切换状态，如处于频段切换2状态。电子设备处于频段切换1状态的时间可以与处于频段切换2状态的时间相同，也可以不同，在此不做任何限定。P2P时间片状态和STA时间片状态的持续时间可以根据实际需求进行设置，可以设置为相同，也可以设置为不同，在此不做任何限定。
可以理解的是，图4所示的电子设备状态的示意图仅做举例说明，不构成任何限制，例如，在本申请的一些实施例中，STA时间片可以在P2P时间片之前。同时，不同的电子设备中的P2P时间片状态、STA时间片状态、频段切换1状态、频段切换2状态的持续时间可以相同，也可以不同，在此不做任何限定。
若多屏协同系统中建立协同的一个电子设备为DBAC模式(如电子设备1)，另一个电子设备为DBDC模式(如电子设备2)，且该多屏协同系统的数据传输情形为异频异信道。如图5所示，当电子设备1处于P2P时间片状态时，电子设备1与电子设备2之间可以进行数据传输，电子设备1与路由器之间不可以进行数据传输。当电子设备1处于频段切换1状态时，电子设备1与电子设备2之间和电子设备1与路由器之间都不可以进行数据传输。当电子设备1处于STA时间片状态时，电子设备1与电子设备2之间不可以进行数据传输，电子设备1与路由器之间可以进行数据传输。当电子设备1处于频段切换2状态时，电子设备1与电子设备2之间和电子设备1与路由器之间都不可以进行数据传输。电子设备2与路由器之间的数据传输在图5中未示出，可以理解的是，电子设备2为DBDC模式，电子设备2可以同时在2.4GHz频段和5GHz频段上工作进行数据传输，所以电子设备2可以同时进行实现与电子设备1之间的数据传输和与路由器之间的数据传输，无需如电子设备1一样进行状态切换。
也就是说，当多屏协同系统中建立协同的一个电子设备为DBAC模式，另一个电子设备为DBDC模式时，只有在为DBAC模式的电子设备处于P2P时间片状态时，两个电子设备之间才能进行数据传输，否则，两个电子设备之间不能进行数据传输。在为DBAC模式的电子设备处于STA时间片状态时，该电子设备才能与路由器之间进行数据传输。由两个不同模式的电子设备建立的多屏协同系统中，路由器与为DBAC模式的电子设备进行数据传输时，需要等待为DBAC模式的电子设备处于STA时间片状态，也就是说，为DBAC模式的电子设备处于其它状态(非STA时间片状态的状态)时，路由器不能与为DBAC模式的电子设备进行数据传输；为DBDC模式的电子设备与为DBAC模式的电子设备进行数据传输时，需要等待为DBAC模式的电子设备处于STA时间片状态，也就是说，为DBAC模式的电子设备处于其它状态(非STA时间片状态的状态)时，为DBDC模式的电子设备不能与为DBAC模式的电子设备进行数据传输，导致数据传输效率较差。
若多屏协同系统中建立协同的两个电子设备都为DBAC模式，且该多屏协同系统的数据传输情形为异频异信道时，两个电子设备同时处于P2P时间片状态时，两个电子设备之间可以进行数据传输。例如，如图6所示，一多屏协同系统中手机10与平板电脑20都为DBAC模式，且该多屏协同系统的数据传输情形为异频异信道。当手机10与平板电脑20同时处于P2P时间片状态时，手机10与平板电脑20之间可以进行数据传输。当手机10与平板电脑20并非同时处于P2P时间片时，手机10与平板电脑20之间不可以进行数据传输。例如，当手机10处于P2P时间片状态但平板电脑20处于频段切换1状态时，手机10与平板电脑20之间不可以进行数据传输；平板电脑20处于P2P时间片但手机10处于频段切换2时，手机10与平板电脑20之间不可以进行数据传输。可以理解的是，当手机10处于STA时间片状态时，手机10与路由器之间可以进行数据传输。当平板电脑20处于STA时间片状态时，平板电脑20与路由器之间可以进行数据传输。
也就是说，当多屏协同系统中建立协同的两个电子设备都为DBAC模式，且该多屏协同系统的数据传输情形为异频异信道时，只有在两个电子设备都处于P2P时间片状态时，两个电子设备之间才能进行数据传输，否则，两个电子设备之间不能进行数据传输。一电子设备 只有在处于STA时间片状态时，才能与路由器之间进行数据传输。由两个DBAC模式的电子设备建立的多屏协同系统中，很多时间都不能进行数据传输，导致数据传输效率较差。
为了解决多屏协同系统中DBAC场景(DBSC场景)带来的数据传输较差的问题，数据传输效率较差的问题，本申请实施例提供一种数据传输管理方法，所述方法应用于包括第一电子设备，接入点设备通过第一链路为所述第一电子设备提供无线通信网络，所述方法可以有效减少多屏协同系统中不能进行数据传输的时间，提高数据传输效率。下面结合附图，对数据传输管理方法进行详细介绍。
图7为本申请实施例提供的一种数据传输管理方法的流程示意图。所述方法应用于第一电子设备，所述第一电子设备与无线接入点(如路由器，下文以无线接入点为路由器为例进行说明)之间存在第一链路(Wi-Fi链路)。路由器通过第一链路为第一电子设备提供无线通信网络。如图7所示，所述方法包括：
700，接收用户操作。用户操作用于确定与第一电子设备建立链路进行数据传输的第二电子设备。所述第二电子设备与路由器之间存在第二链路(Wi-Fi链路)。路由器通过第二链路为第二电子设备提供无线通信网络。
所述用户操作包括多屏协同操作(下文以用户操作为多屏协同操作为例进行说明)。所述多屏协同操作用于控制第一电子设备与第二电子设备建立协同连接，如建立进行协同连接的P2P链路。用户点击电子设备(第一电子设备或第二电子设备)上多屏协同控件时可以触发所述多屏协同操作。用户点击多屏协同控件后，电子设备(第一电子设备或第二电子设备)上可以出现多屏协同提示，用户点击所述多屏协同提示时可以触发所述多屏协同操作。所述P2P链路用于传输第一电子设备和第二电子设备的多屏协同数据。多屏协同数据为第一电子设备与第二电子设备建立协同连接时互相传输的数据，如用于投屏的视频流，以及用于协同控制操作指令(如第一电子设备通过P2P链路把对第二电子设备的控制操作指令发送给第二电子设备，使得第二电子设备执行相应的操作)。
在本申请的一些实施例中，接收用户操作后，建立第一电子设备与第二电子设备进行数据传输的链路。本申请对建立数据传输的链路的执行时刻不做任何限制，可以在图7中700之后的任意时刻执行，例如，可以在701之后、在705之后。
701，第一电子设备获取第二电子设备的Wi-Fi能力信息。
在本申请的一些实施例中，当第一电子设备与第二电子设备之间没有响应多屏协同操作建立P2P链路时，第一电子设备可以通过蓝牙(Bluetooth，BT)或NFC通信等方式与第二电子设备进行数据传输，获取第二电子设备的Wi-Fi能力信息。例如，第一电子设备与第二电子设备的距离小于预设距离阈值时，基于NFC通信可从第二电子设备上获取第二电子设备的Wi-Fi能力信息。若第一电子设备与第二电子设备之间已响应多屏协同操作建立P2P链路，第一电子设备可以通过蓝牙、NFC或Wi-Fi通信等方式与第二电子设备进行数据传输，获取第二电子设备的Wi-Fi能力信息。Wi-Fi能力信息可以用于表示电子设备进行无线通信的性能信息。Wi-Fi能力信息可以包括DBDC能力、理论峰值速率。DBDC能力可用于判断电子设备能否可以在DBDC模式下进行数据传输。若一电子设备具有DBDC能力，确定该电子设备能在DBDC模式下进行数据传输。理论峰值速率用于表示电子设备的数据传输的最大传输速率。Wi-Fi能力信息中还可以信道切换通知(Channel Switch Announcement，CSA)能力。一电子设备与其他电子设备(如电子设备W)建立协同连接时具有CSA能力，表明该电子设备在与电子设备W进行数据传输的时候可以自动发起信道切换，电子设备W会基于该电子设 备发起的信道切换进行信道切换。建立协同的两个设备中被确定为组织者(Group owner，GO)的电子设备具有CSA能力，确定为参与者(Gower Client，GC)的电子设备不具备有CSA能力。可以理解的是，第一电子设备可以是GC，也可以是GO。
Wi-Fi能力信息中还可以包括当前连接路由器的信息，即第二电子设备当前连接的路由器的信息。所述当前连接路由器的信息可以包括；已连接的Wi-Fi名称、已连接的Wi-Fi基本服务集标识(Basic Service Set Identifier，BSSID)。可以基于当前连接路由器的信息确定第一电子设备与第二电子设备是否连接同一个Wi-Fi。所述当前连接路由器的信息中还可以包括与路由器进行数据传输时工作的频段。根据当前连接路由器的信息，可以确定电子设备与路由器进行通信时，电子设备工作的频段，如5GHz、2.4GHz。
在本申请的一些实施例中，第一电子设备会发送自身的Wi-Fi能力信息至第二电子设备。第一电子设备可以在获取第二电子设备的Wi-Fi能力信息的同时，向第二电子设备发送自身的Wi-Fi能力信息，或者第一电子设备可以在获取第二电子设备的Wi-Fi能力信息之后，向第二电子设备发送自身的Wi-Fi能力信息，当然也可以在获取第二电子设备的Wi-Fi能力信息之前，向第二电子设备发送自身的Wi-Fi能力信息。第二电子设备接收第一电子设备发送的Wi-Fi能力信息后，也可以进行传输能力比对，确定其传输能力是否强于第二电子设备。
702，第一电子设备确定第一电子设备和第二电子设备是否都具有DBDC能力。
一电子设备具有DBDC能力说明其传输能力好。若第一电子设备和第二电子设备都具有DBDC能力，说明第一电子设备、第二电子设备和路由器构成的多屏协同系统中数据传输能力好，不需要改变常规的多屏协同系统中的组网，执行71，传统组网，流程结束。传统组网为第一电子设备、第二电子设备和路由器构成的多屏协同系统为三角形结构的组网。例如，如图1所示，平板电脑20与手机10之间存在一条P2P链路，平板电脑20与路由器30之间存在一条Wi-Fi链路，手机10与路由器30之间存在一条Wi-Fi链路，三条链路构成三角结构的组网。若第一电子设备和第二电子设备中存在一个电子设备不具有DBDC能力，按照常规的多屏协同系统中的组网方式进行组网，可能会出现一电子设备的工作模式为DBAC模式，导致数据传输能力较差(可以参见对图5和图6相关介绍中，关于工作模式为DBAC模式的电子设备工作场景的相关说明)。所以若第一电子设备和第二电子设备不都具有DBDC能力，执行703，确定第一链路与第二链路所在的频段是否都为第一频段。所述第一频段可以根据多屏协同时第一电子设备与第二电子设备的P2P通道所处的频段进行设置，例如P2P通道所处的频段为5GHz，将所述第一频段设置为5GHz。P2P通道所处的频段可以根据第一电子设备和第二电子设备的硬件结构进行确定，例如，若第一电子设备和第二电子设备都具有两个基带处理模块时，确定P2P通道所处的频段为5GHz。若第一链路所处的频段(或第二链路所处的频段)不为第一频段时，第一链路所处的频段(或第二链路所处的频段)可以为预设频段，如2.4GHz。也就是说，若一第一链路(或一第二链路)所处的频段不为5GHz时，该第一链路(或该第二链路)所处的频段为2.4GHz。
若第一链路与第二链路所在的频段都为第一频段，不需要改变常规的多屏协同系统中的组网，执行71，传统组网，流程结束。例如，第一链路与第二链路所在的频段都为5GHz，按照传统的方式进行组网。
若第一链路与第二链路所在的频段不都为第一频段，执行704，确定第一电子设备是否具有DBDC能力。若第一电子设备具有DBDC能力，执行705，第一电子设备发送连接信息至第二电子设备，建立Wi-Fi链路。所述连接信息用于与第一电子设备建立Wi-Fi链路。连接 信息可以包括第一电子设备的设备连接名称和设备连接密码。第二电子设备根据接收到的连接信息与第一电子设备建立Wi-Fi链路。建立Wi-Fi链路后，第一电子设备可以被称为模拟路由器(Soft Access Point，Soft-AP)。Soft-AP可以实现路由器的功能，为其他的电子设备提供无线通信网络(Wi-Fi)。一电子设备开启Soft-AP的功能后，可以和普通的路由器一样，为其他的电子设备提供Wi-Fi。电子设备可以通过自身的蜂窝网络(如2G、3G、4G、5G等)开启Soft-AP功能为其它电子设备提供Wi-Fi，如分享热点，其他电子设备可以通过该电子设备的热点连接无线通信网络，也可以通过自身连接的路由器(如通过共享Wi-Fi信号)开启Soft-AP功能，为其它电子设备提供Wi-Fi。在此不对电子设备开启Soft-AP功能的方法进行限定。
可以理解的是，第二电子设备与第一电子设备建立Wi-Fi链路后，会断开与路由器的连接，也就是断开第二链路。例如，第一电子设备为手机10，第二电子设备为平板电脑20，将手机10确定为Soft-AP，图8为本申请实施例提供的一种多屏协同系统的示意图。图8中(a)为将第一电子设备确定为Soft-AP之前的多屏协同系统示意图。如图8中(a)所示，手机10与平板电脑20之间包括进行数据传输的P2P通道；手机10与路由器30之间和平板电脑20与路由器30包括进行数据传输的Wi-Fi通道。图8中(b)为将第二电子设备与第一电子设备建立Wi-Fi链路后的多屏协同系统示意图。如图8中(b)所示，手机10开启Soft-AP功能后，手机10与平板电脑20之间包括进行数据传输的P2P通道和Wi-Fi通道；手机10与路由器30之间包括进行数据传输的Wi-Fi通道。可以理解的是，图8所示的场景为在将手机10确定为Soft-AP之前，建立手机10与平板电脑20之间进行数据传输的P2P通道的示意图，在本申请的另一些实施例中，可以在将手机10确定为Soft-AP之后，建立手机10与平板电脑20之间进行数据传输的P2P通道。
因为手机10开启Soft-AP功能之前，平板电脑20与路由器30之间Wi-Fi通道和平板电脑20与手机10之间的频段可能为不同的频段，平板电脑20分别与路由器30和手机10进行数据传输时，平板电脑20需要进行频段切换(如从2.4GHz切换至5GHz，或从5GHz切换至2.4GHz)，手机10开启Soft-AP功能之后，平板电脑20与路由器30之间Wi-Fi通道被取消了仅保留了平板电脑20与手机10之间的P2P通道和Wi-Fi通道，平板电脑20与手机10之间的P2P通道和Wi-Fi通道可以在同一个频段(如5GHz)下进行数据传输，所以平板电脑20使用P2P通道和Wi-Fi通道时无需进行频段切换，避免了频段切换带来的时间损耗，提高数据传输效率。
若第一电子设备不具有DBDC能力，执行706，确定第二电子设备是否具有DBDC能力。若第二电子设备具有DBDC能力，第二电子设备可以作为Soft-AP。第一电子设备在确定第二电子设备可以作为Soft-AP，可以通知第二电子设备可以作为Soft-AP。或者，在一本申请的一些实施例中，第二电子设备也会获取第一电子设备的Wi-Fi能力信息，并可以根据第一电子设备的Wi-Fi能力信息确定是否将自己作为Soft-AP(确认流程可以如图7中702至706所示)。第二电子设备知道自己可以作为Soft-AP时，开启Soft-AP功能，并发送连接信息至所述第一电子设备。所述连接信息用于与第二电子设备建立Wi-Fi链路。连接信息可以包括第二电子设备的设备连接名称和设备连接密码。第二电子设备根据第一电子设备的通知，开启Soft-AP功能后，可以主动将连接信息发送至第一电子设备。若第二电子设备具有DBDC能力，执行707，第一电子设备接收第二电子设备的连接信息，建立Wi-Fi链路。第一电子设备与第二电子设备建立Wi-Fi链路后，执行708，断开与路由器的连接，也就是断开第一链路。 例如，第一电子设备为手机10，第二电子设备为平板电脑20，将平板电脑20确定为Soft-AP，图9为本申请实施例提供的一种多屏协同系统的示意图。图9中(a)为将第二电子设备确定为Soft-AP之前的多屏协同系统示意图。如图9中(a)所示，手机10与平板电脑20之间包括进行数据传输的P2P通道；手机10与路由器30之间和平板电脑20与路由器30包括进行数据传输的Wi-Fi通道。图9中(b)为将第一电子设备与第二电子设备建立Wi-Fi链路后的多屏协同系统示意图。如图9中(b)所示，平板电脑20开启Soft-AP功能后，手机10与平板电脑20之间包括进行数据传输的P2P通道和Wi-Fi通道；平板电脑20与路由器30之间包括进行数据传输的Wi-Fi通道。可以理解的是，图9所示的场景为在将平板电脑20确定为Soft-AP之前，先建立手机10与平板电脑20之间进行数据传输的P2P通道的示意图，在本申请的另一些实施例中，可以在将平板电脑20确定为Soft-AP之后，再建立手机10与平板电脑20之间进行数据传输的P2P通道。
因为平板电脑20开启Soft-AP功能之前，手机10与路由器30之间Wi-Fi通道和手机10与平板电脑20之间的频段可能为不同的频段，手机10分别与路由器30和手机10进行数据传输时，手机10需要进行频段切换(从2.4GHz切换至5GHz，或从5GHz切换至2.4GHz)，平板电脑20开启Soft-AP功能之后，手机10与路由器30之间Wi-Fi通道被取消了仅保留了手机10与平板电脑20之间的P2P通道和Wi-Fi通道，手机10与平板电脑20之间的P2P通道和Wi-Fi通道可以在同一个频段(如5GHz)下进行数据传输，所以手机10使用P2P通道和Wi-Fi通道时无需进行频段切换，避免了频段切换带来的时间损耗，提高数据传输效率。
若第二电子设备不具有DBDC能力，执行709，确定第一电子设备的理论峰值速率是否大于第二电子设备的理论峰值速率。若第一电子设备的理论峰值速率大于第二电子设备的理论峰值速率，执行710，第一电子设备发送连接信息至第二电子设备，建立Wi-Fi链路。710的一些具体实施方式可以参见对705的相关说明。
若第一电子设备的理论峰值速率不大于第二电子设备的理论峰值速率，执行711确定第一电子设备的理论峰值速率是否小于第二电子设备的理论峰值速率。若第一电子设备的理论峰值速率小于第二电子设备的理论峰值速率，执行712，接收第二电子设备的连接信息，建立Wi-Fi链路。若第一电子设备与所述第二电子设备建立Wi-Fi链路后，执行713，断开与路由器的连接，也就是断开第二链路。
若第一电子设备的理论峰值速率不小于第二电子设备的理论峰值速率，执行714，基于预设规则发送连接信息至第二电子设备，建立Wi-Fi链路；或基于预设规则，接收第二电子设备的连接信息，建立Wi-Fi链路。也就是说第一电子设备的理论峰值速率等于第二电子设备的理论峰值速率时，可以按照预设的规则在第一电子设备和第二电子设备中确定为Soft-AP。
若基于预设的规则确定将第一电子设备确定为Soft-AP，第一电子设备发送连接信息至第二电子设备，建立Wi-Fi链路。第二电子设备与第一电子设备建立Wi-Fi链路后，会断开与路由器的连接，也就是断开第二链路。若基于预设的规则确定将第二电子设备确定为Soft-AP，第一电子设备接收第二电子设备的连接信息，建立Wi-Fi链路。第一电子设备与第二电子设备建立Wi-Fi链路后，会断开与路由器的连接，也就是断开第一链路。
通过上述实施例，可以减少数据传输场景中使用DBAC模式工作的电子设备个数，例如将多屏协同系统中一电子设备使用DBAC模式工作和一电子设备使用DBDC模式工作的场景，变成多屏协同系统中没有电子设备使用DBAC模式工作的场景，或者，将多屏协同系统中两电子设备使用DBAC模式工作的场景，变成多屏协同系统中仅有一电子设备使用DBAC 模式工作的场景。通过减少多屏协同系统中使用DBAC模式工作的电子设备，可以减少频段切换过程中时间的损耗，能有效减少多屏协同系统中不能进行数据传输的时间，提高数据传输效率。上述实施例可以用于解决电子设备使用DBAC模式(DBSC模式)工作时，P2P链路和上网链路不能同时进行数据传输，需要分时数据传输，带来的数据传输效率降低的技术问题。通过上述实施例，可以减少多屏协同系统中使用DBAC模式工作的电子设备个数，从而提高了多屏协同系统中数据传输效率。可以理解是，P2P信道除了用于多屏协同，也可以用于其他业务，如投屏、文件传输等，所以在投屏场景(文件传输场景)中面临DBAC模式(DBSC模式)带来的数据传输效率降低的技术问题时，使用上述实施例，也可以减少场景中使用DBAC模式工作的电子设备个数，从而提高了数据传输效率。
图7所示的数据传输管理方法中第一电子设备根据第二电子设备的Wi-Fi能力信息，确定是否将自身或第二电子设备作为Soft-AP，改变传统的组网仅为一种举例说明，不构成任何限制。可以理解的，在本申请的一些实施例中，第一电子设备可以向第二电子设备发送第一电子设备的Wi-Fi能力信息和传输能力比对请求。传输能力比对请求用于请求第二电子设备根据第一电子设备的Wi-Fi能力信息，确定是否将自身或第一电子设备作为Soft-AP，改变传统的组网。在本申请的一些实施例中，第一电子设备与第二电子设备可以互相发送Wi-Fi能力信息，各自进行传输能力比对，并根据传输能力对比结果，确定是否将自身或第二电子设备作为Soft-AP，改变传统的组网。例如，第一电子设备与第二电子设备互相发送Wi-Fi能力信息后，第一电子设备根据第二电子设备发送的Wi-Fi能力信息进行传输能力比对，根据传输能力比对确定自己的传输能力强于第二电子设备，确定不断开与路由器的连接，并确定将自身作为Soft-AP为第二电子设备提供Wi-Fi；第二电子设备根据第一电子设备发送的Wi-Fi能力信息进行传输能力比对，根据传输能力比对确定自己的传输能力弱于第一电子设备，确定断开与路由器的连接，确定与第一电子设备建立Wi-Fi连接。第一电子设备确定将自身作为Soft-AP为第二电子设备提供Wi-Fi后，可以将第一电子设备对应的连接信息发送至第二电子设备。若第二电子设备确定与第一电子设备建立Wi-Fi连接且没有接收到第一电子设备发送的连接信息，可以主动向第一电子设备获取连接信息。第二电子设备根据第一电子设备发送的连接信息，与第一电子设备建立连接，建立连接后第一电子设备为所述第二电子设备通过Wi-Fi服务。关于上述实施例的一些具体实施方式，可以参见对图7的相关描述，在此不再赘述。
在本申请的一些实施例中，执行图7中705、710或714所示的步骤后，若第二电子设备与第一电子设备建立Wi-Fi链路成功后或第一电子设备与第二电子设备建立Wi-Fi链路成功后，可以按照预设规则生成并显示相应的提示。所述提示可以用于提示用户多屏协同系统中组网已发生变更。例如，若第二电子设备与第一电子设备建立Wi-Fi链路成功后，可以在第一电子设备的显示界面上显示第一提示，第一提示用于提示第一电子设备正在为第二电子设备提供Wi-Fi服务；也可以在第二电子设备的显示界面上显示第二提示，第二提示用于提示第二电子设备正通过第一电子设备提供的Wi-Fi服务进行上网。
在本申请的一些实施例中，执行图7中705、710或714所示的步骤后，若第二电子设备与第一电子设备建立Wi-Fi链路成功后，确定第二电子设备与第一电子设备进行数据传输的频段是否和第一电子设备与路由器进行数据传输的频段相同。若第二电子设备与第一电子设备进行数据传输的频段与第一电子设备与路由器进行数据传输的频段相同，根据第一电子设备与路由器进行数据传输的信道，确定是否调整第二电子设备与第一电子设备进行数据传输 的信道。若第一电子设备与路由器进行数据传输的信道和第二电子设备与第一电子设备进行数据传输的信道不一致，确定调整第二电子设备与第一电子设备进行数据传输的信道，即当前的多屏协同系统为同频异信道时进行信道切换，使得切换后的多屏协同系统为同频同信道；否则，确定不调整第二电子设备与第一电子设备进行数据传输的信道，即当前的多屏协同系统中为同频同信道时，无需调整第二电子设备与第一电子设备进行数据传输的信道。
可以理解的是，当前的多屏协同系统为同频异信道时，多屏协同系统中的GO可以主动发起信道切换。GC在GO发起信道切换后，会响应于GO发起的信道切换进行信道切换，从而使得GO与GC进行数据传输的信道得以切换。GO和GC的相关说明，可以参见对图7中步骤701的相关描述，在此不再赘述。
例如，如图10中(a)所示，手机10与路由器30进行数据传输的频段和手机10与平板电脑20进行数据传输的频段一致(都为5G)，确定当前的多屏协同系统中存在同频；手机10与路由器30进行数据传输的信道(信道1)和手机10与平板电脑20进行数据传输的信道(信道2)不一致，确定当前的多屏协同系统为同频异信道。同频异信道的情况下，对手机10与平板电脑20进行数据传输的信道进行信道切换，使得多屏协同系统变为同频同信道。若手机10为GO，手机10可以主动发起信道切换。平板电脑20在手机10发起信道切换后，会响应于手机10发起的信道切换进行信道切换。如图10中(b)所示，将手机10与平板电脑20进行数据传输的信道从信道2切换为信道1，使得多屏协同系统变为同频同信道。
上述实施例，通过将多屏协同系统中的同频异信道变为同屏同信道，可以进一步提高数据传输的效率。
在本申请的一些实施例中，执行图7中705、710或714所示的步骤后，若第二电子设备与第一电子设备建立Wi-Fi链路成功后，可以监测第二电子设备与第一电子设备进行数据传输的信道，若第二电子设备与第一电子设备进行数据传输的信道发生变化时，确定第二电子设备与第一电子设备进行数据传输的频段是否和第一电子设备与路由器进行数据传输的频段相同；若第二电子设备与第一电子设备进行数据传输的频段与第一电子设备与路由器进行数据传输的频段相同，根据第一电子设备与路由器进行数据传输的信道，确定是否调整第二电子设备与第一电子设备进行数据传输的信道。即根据第一电子设备与路由器进行数据传输的信道，确定当前的多屏协同系统是否为同频异信道，若当前的多屏协同系统为同频异信道，确定需要调整第二电子设备与第一电子设备进行数据传输的信道，使之成为同频同信道。在第二电子设备与第一电子设备进行数据传输的信道发生变化时，确定是否调整多屏协同系统中的数据传输情形，可以及时地确定是否需要对多屏协同系统中的数据传输情形进行调整，从而可以有效保证多屏协同系统中数据传输效率。
在本申请的一些实施例中，执行图7中707、712或714所示的步骤后，若第一电子设备与第二电子设备建立Wi-Fi链路成功后，确定第一电子设备与第二电子设备进行数据传输的频段是否和第二电子设备与路由器进行数据传输的频段相同；若第二电子设备与第一电子设备进行数据传输的频段与第一电子设备与路由器进行数据传输的频段相同，根据第二电子设备与路由器进行数据传输的信道，确定是否调整第一电子设备与第二电子设备进行数据传输的信道。该实施例的一些具体实施方式可以参见上述实施例的相关描述，在此不再赘述。
由于执行图7中705、710或714所示的步骤后，第一电子设备与路由器进行连接，第二电子设备不与路由器进行连接，若此时第二电子设备为GO，第二电子设备判断当前的多屏协同系统是否为同频异信道时，不能直接获取多屏协同中与路由器进行数据传输的信道(即 第一电子设备与路由器进行数据传输的信道)，需要通过第一电子设备才能获取，所以第二电子设备判断当前的多屏协同系统是否为同频异信道不是很便利，导致发起主动信道切换的速度较慢。或者，由于执行图7中707、712或714所示的步骤后，第二电子设备与路由器进行连接，第一电子设备不与路由器进行连接，若此时第一电子设备为GO，第一电子设备判断当前的多屏协同系统是否为同频异信道时，不能直接获取多屏协同中与路由器进行数据传输的信道(即第二电子设备与路由器进行数据传输的信道)，需要通过第二电子设备才能获取，所以第一电子设备判断当前的多屏协同系统是否为同频异信道不是很便利，导致发起主动信道切换的速度较慢。
基于上述原因，在本申请的一些实施例中，可以根据Soft-AP，在第一电子设备和第二电子设备中重新确定GO。例如，若第一电子设备为Soft-AP，将第一电子设备确定为GO；若第二电子设备为Soft-AP，将第二电子设备确定为GO。通过将Soft-AP对应的电子设备确定为GO，可以使得在多屏协同系统中存在同频的情况下，GO可以直接确定与路由器进行数据传输的信道，并根据与路由器进行数据传输的信道，确定是否主动发起信道切换，以使GO与路由器进行数据传输的信道和GC与GO进行数据传输的信道一致。因为GO和路由器、GC直接进行数据传输，可以直接获取与路由器和GC的数据传输信息(数据传输频段、数据传输信道)，并根据数据传输信息确定是否主动发起信道切换，可以便利地确定当前的多屏协同系统是否为同频异信道，提高了确定是否信道切换的速度。
例如，如图10中(a)所示，若手机10为GO，手机10直接与平板电脑20、路由器30进行数据传输。所以可以直接获取数据传输信息，并根据数据传输信息确定是否控制平板电脑20进行信道切换。若平板电脑20为GO，平板电脑20没有直接与路由器30进行数据传输，平板电脑20不能直接获取手机10与平板电脑20的数据传输信息，需要通过与手机10之间的数据传输才能获取手机10与平板电脑20的数据传输信息，所以导致平板电脑20获取数据传输信息的时间较长。
上述实施例，根据Soft-AP，在第一电子设备和第二电子设备中重新确定GO后，可以便利地确定当前的多屏协同系统是否为同频异信道，提高了确定是否信道切换的速度。
在本申请一些实施例中，如图11所示，执行完图7中702所示的步骤后，若第一电子设备和第二电子设备不都具有DBDC能力，执行803、确定第一电子设备是否具有DBDC能力。若第一电子设备具有DBDC能力，执行804，第一电子设备发送连接信息至第二电子设备，建立Wi-Fi链路。若第一电子设备不具有DBDC能力，执行805，确定第二电子设备是否具有DBDC能力。若第二电子设备具有DBDC能力，执行806，第一电子设备接收第二电子设备的连接信息，建立Wi-Fi链路。第一电子设备与第二电子设备建立Wi-Fi链路后，执行807，断开与路由器的连接。若第二电子设备不具有DBDC能力，执行808，确定第一电子设备的理论峰值速率是否大于第二电子设备的理论峰值速率。若第一电子设备的理论峰值速率大于第二电子设备的理论峰值速率，执行809，第一电子设备发送连接信息至第二电子设备，建立Wi-Fi链路。若第一电子设备的理论峰值速率不大于第二电子设备的理论峰值速率，执行810确定第一电子设备的理论峰值速率是否小于第二电子设备的理论峰值速率。若第一电子设备的理论峰值速率小于第二电子设备的理论峰值速率，执行811，接收第二电子设备的连接信息，建立Wi-Fi链路。若第一电子设备与所述第二电子设备建立Wi-Fi链路后，执行812断开与路由器的连接。若第一电子设备的理论峰值速率不小于第二电子设备的理论峰值速率，执行813，基于预设规则发送连接信息至第二电子设备，建立Wi-Fi链路；或基于预设规则， 接收第二电子设备的连接信息，建立Wi-Fi链路。
图11中803-813的一些具体实施方式，可以参见对图7的相关说明，在此不再赘述。
通过上述实施例，可以减少数据传输场景中使用DBAC模式工作的电子设备个数，例如将多屏协同系统中一电子设备使用DBAC模式工作和一电子设备使用DBDC模式工作的场景，变成多屏协同系统中没有电子设备使用DBAC模式工作的场景，或者，将多屏协同系统中两电子设备使用DBAC模式工作的场景，变成多屏协同系统中仅有一电子设备使用DBAC模式工作的场景。通过减少多屏协同系统中使用DBAC模式工作的电子设备，可以减少频段切换过程中时间的损耗，能有效减少多屏协同系统中不能进行数据传输的时间，提高数据传输效率。
