下面对本申请实施例进行详细介绍。
请参阅图1，图1是本申请实施例公开的一种基于双WiFi模块的数据分流方法的流程示意图，如图1所示，该基于双WiFi模块的数据分流方法包括如下步骤。
101，在双WiFi模式下，移动终端基于应用类型分流策略、数据包类型分流策略、链路质量分流策略、接入点AP类型分流策略中的至少一种分流策略确定第一WiFi通路和第二WiFi通路之间的数据包分配比例。
其中，第一WiFi通路包括第一WiFi模块连接的数据通路，第二WiFi通路包括第二WiFi模块连接的数据通路。
本申请实施例中，无线保真(WIreless-Fidelity，WiFi)，也可以称为wifi、Wi-Fi，是一种无线连接方式。移动终端可以包括双WiFi模块。双WiFi模块可以包括第一WiFi模块(也可以称为第一WiFi通信模块)和第二WiFi模块(也可以称为第二WiFi通信模块)，可以支持两个WiFi频段的信号的同时收发，两个WiFi频段的信号互不干扰。双WiFi模块 可以同时连接两个WiFi热点，支持两个WiFi通路(第一WiFi通路和第二WiFi通路)的数据收发。第一WiFi模块和第二WiFi模块支持的频段不同，比如，第一WiFi模块支持2.4G(Hz)频段，第二WiFi模块支持5G(Hz)频段；或者，第一WiFi模块支持5G频段，第二WiFi模块支持2.4G频段。第一WiFi通路是移动终端和无线网络之间建立的通过第一WiFi模块连接的数据通路。第二WiFi通路是移动终端和无线网络之间建立的通过第二WiFi模块连接的数据通路。
本申请的第一WiFi模块和第二WiFi模块均处于Station模式(简称STA模式)，第一WiFi模块和第二WiFi模块需要接入WiFi热点来接入WiFi网络。WiFi热点，为接入点(Access Point，AP)的一种。AP可以为无线AP。
双WiFi模式是两个WiFi模块同时收发数据的模式，在双WiFi模式下，第一WiFi模块和第二WiFi模块同时工作，互不干扰。与双WiFi模式对应的是单WiFi模式，单WiFi模式是仅有一个WiFi模块工作的模式，只能同时支持一个WiFi频段的信号的收发。本申请实施例的双WiFi模块具有双频双发(Dual Band Dual Concurrent，DBDC)功能，支持2×2天线，2组天线都配套有放大电路和功放芯片，可以支持天线同时发射和接收信号。
本申请实施例的移动终端可以根据数据分流策略确定第一WiFi通路和第二WiFi通路之间的数据包分配比例，以确定在两个数据通路之间的数据传输比例。数据分流策略可以包括应用类型分流策略、数据包类型分流策略、链路质量分流策略、接入点AP类型分流策略中的一种或多种组合。应用类型分流策略是将不同的应用的数据通过不同的WiFi通路传输。数据包类型分流策略是将不同数据类型的数据包通过不同的WiFi通路传输，比如，数据包类型分流策略可以根据不同数据类型的数据包所要求的最低网络延时、最低数据传输速率选择不同的WiFi通路。链路质量分流策略是根据两个WiFi通路的链路质量确定数据包在两个WiFi通路的传输比例。接入点AP类型分流策略是根据两个WiFi通路连接的接入点AP的类型确定数据包在两个WiFi通路的传输比例。
不同的数据分流策略可以适用不同的场景，比如，应用类型分流策略可以用于网络数据传输质量要求较高的应用的使用场景，有些应用为了保证运行流畅，需要使用双WiFi模式，而有些应用对网络数据传输质量要求较低，不需要使用双WiFi模式，仅使用单WiFi模式即可。当有多个应用都需要进行网络数据传输时，可以依据不同的WiFi通路分别对应不同的应用数据的传输。应用数据，指的是应用程序与网络之间交互的数据。数据包类型分流策略可以用于大流量的数据包的使用场景。例如，当检测到有视频流数据包传输时，可以启用数据包类型分流策略。
其中，应用类型分流策略、数据包类型分流策略、链路质量分流策略、接入点AP类型分流策略也可以形成组合分流策略。比如，数据包类型分流策略与接入点AP类型分流策略组合的分流策略，可以综合考虑数据包类型和接入点AP的类型。例如，第一AP为限速型AP(比如，限制下载速率为1MB/S)，第二AP为不限速型AP，需要传输的数据包包括下载速率要求较高的视频流数据包和下载速度要求较低的控制类数据包，则将视频流数据包分配到第二AP上进行传输，将控制类数据包分配到第一AP上进行传输。
102，移动终端将需要传输的数据包按照数据包分配比例分配在第一WiFi通路和第二WiFi通路中传输。
本申请实施例中，移动终端可以发送上行数据包，也可以接收下行数据包。需要传输的数据包可以是上行数据包，也可以是下行数据包。对于上行数据包，移动终端可以将上行数据包分配在第一WiFi上行通路和第二WiFi上行通路中传输；对于下行数据包，移动终端可以将下行数据包分配在第一WiFi下行通路和第二WiFi下行通路中传输。
需要传输的数据包可以是移动终端中不同的业务发起的，比如，需要传输的数据包可以是视频类业务、游戏类业务、语音类业务、即时通讯类业务中的任意一种业务发起的。
本申请实施例中的双WiFi模式，是同时开启两个WiFi网络来进行网络访问的链路聚合。链路聚合，是设备可以同时使用两个或者两个以上的网口同时进行上网，指的是把用户的上网请求智能的分配到不同的可上网接口(第一WiFi通信模块接口、第二WiFi通信模块接口)上。
本申请实施例采用双WiFi模块，双WiFi模块可以支持两条WiFi通路同时收发数据，移动终端可以将需要传输的数据包分配在第一WiFi通路和第二WiFi通路中传输，从而提高WiFi网络的数据传输量。
可选的，步骤101中，移动终端基于应用类型分流策略确定第一WiFi通路和第二WiFi通路之间的数据包分配比例，包括：
移动终端确定当前运行的前台应用的类型，根据前台应用类型与数据包分配比例的对应关系确定与当前运行的前台应用的类型对应的目标数据包分配比例；
步骤102中，移动终端将需要传输的数据包按照数据包分配比例分配在第一WiFi通路和第二WiFi通路中传输，包括：
移动终端将需要传输的数据包按照目标数据包分配比例分配在第一WiFi通路和第二WiFi通路中传输。
本申请实施例中，前台应用为移动终端在前台运行的应用，也可以称为前景应用。第一WiFi通路和第二WiFi通路中，一个为2.4G频段，另一个为5G频段。由于不同类型的前台应用在不同频段的WiFi通路中的传输效果(比如，传输时延、丢包率、下行传输速率、上行传输速率等)不同，不同类型的前台应用的数据包分配比例也是不同的，这个数据包分配比例可以由用户预先进行设定，也可以由移动终端根据历史统计的分配比例与数据包传输效果综合确定，以寻求不同的应用的数据包最佳传输效果。比如，第一类型的前台应用在第一WiFi通路和第二WiFi通路中的分配比例为X1：X2，第二类型的前台应用在第一WiFi通路和第二WiFi通路中的分配比例为Y1：Y2，第三类型的前台应用在第一WiFi通路和第二WiFi通路中的分配比例为Z1：Z2。举例来说，如果当前运行的前台应用的类型为第一类型，则移动终端将需要传输的数据包按照X1：X2的分配比例分配在第一WiFi通路和第二WiFi通路中传输。
本申请实施可以根据应用类型来确定需要传输的数据包在第一WiFi通路和第二WiFi通路中的分配比例，优化双WiFi模式下的应用使用体验，满足不同类型的应用在双WiFi模式下的上网体验，进一步提高不同类型的应用在双WiFi模式下的数据传输量。
可选的，步骤101中，移动终端基于数据包类型分流策略确定第一WiFi通路和第二WiFi通路之间的数据包分配比例，包括：
移动终端获取需要传输的数据包的类型，根据数据包类型与WiFi通路的对应关系确定需要传输的数据包在第一WiFi通路和第二WiFi通路之间的数据包分配比例。
本申请实施例中，第一WiFi通路和第二WiFi通路中，一个为2.4G频段，另一个为5G频段。由于不同类型的数据包在不同频段的WiFi通路中的传输效果(比如，传输时延、丢包率、下行传输速率、上行传输速率等)不同，不同类型的数据包在两个WiFi通路中的分配比例也是不同的，这个数据包分配比例可以由用户预先进行设定，也可以由移动终端根据历史统计的分配比例与数据包传输效果综合确定，以寻求不同类型的数据包的最佳传输效果。比如，第一类型的数据包在第一WiFi通路和第二WiFi通路中的分配比例为X1：X2，第二类型的数据包在第一WiFi通路和第二WiFi通路中的分配比例为Y1：Y2，第三类型的数据包在第一WiFi通路和第二WiFi通路中的分配比例为Z1：Z2。举例来说，如果需要传输的数据包为第一类型，则移动终端将需要传输的数据包按照X1：X2的分配比例分配在第一WiFi通路和第二WiFi通路中传输。
本申请实施可以根据数据包的类型来确定需要传输的数据包在第一WiFi通路和第二 WiFi通路中的分配比例，优化双WiFi模式下的应用使用体验，满足不同类型的应用在双WiFi模式下的上网体验，进一步提高不同类型的数据包在双WiFi模式下的数据传输效果。
可选的，步骤101中，移动终端基于链路质量分流策略确定第一WiFi通路和第二WiFi通路之间的数据包分配比例，包括：
移动终端检测第一WiFi通路的链路质量，检测第二WiFi通路的链路质量，
移动终端根据第一WiFi通路的链路质量、第二WiFi通路的链路质量确定第一WiFi通路和第二WiFi通路之间的数据包分配比例。
第一WiFi通路的链路质量可以通过第一WiFi通路的上下行数据传输速率、往返时延、丢包率、误码率等确定。其中，上下行数据传输速率越高、往返时延越小、丢包率越低、误码率越低、该第一WiFi通路的链路质量越高；上下行数据传输速率越低、往返时延越大、丢包率越高、误码率越高、该第一WiFi通路的链路质量越低。类似的，第二WiFi通路的链路质量可以通过第二WiFi通路的上下行数据传输速率、往返时延、丢包率、误码率等确定。
第一WiFi通路可以包括第一WiFi上行通路和第一WiFi下行通路。第一WiFi上行通路的质量可以通过第一WiFi通路的上行数据传输速率、往返时延、丢包率、误码率等确定。第一WiFi下行通路的质量可以通过第一WiFi通路的下行数据传输速率、往返时延、丢包率、误码率等确定。类似的，第二WiFi通路可以包括第二WiFi上行通路和第二WiFi下行通路。
误码率，是衡量数据在规定时间内数据传输精确性的指标，误码率＝传输中的误码/所传输的总码数*100％。
丢包率，是数据包丢失部分与所传数据包总数的比值。
可选的，移动终端检测第一WiFi通路的链路质量，具体可以包括如下步骤：
移动终端测量第一WiFi通路的数据传输速率、往返时延、丢包率、误码率，基于第一WiFi通路的往返时延、数据传输速率、丢包率、误码率确定第一WiFi通路的链路质量；
移动终端检测第二WiFi通路的链路质量，具体可以包括如下步骤：
移动终端测量第二WiFi通路的数据传输速率、往返时延、丢包率、误码率，基于第二WiFi通路的往返时延、数据传输速率、丢包率、误码率确定第二WiFi通路的链路质量；
移动终端检测移动通路的链路质量，具体可以包括如下步骤：
移动终端测量移动通路的数据传输速率、往返时延、丢包率、误码率，基于移动通路的往返时延、数据传输速率、丢包率、误码率确定移动通路的链路质量。
本申请实施例中，如果第一WiFi通路的链路质量要优于第二WiFi通路的链路质量，则确定第一WiFi通路的数据包占比高于第二WiFi通路的数据包占比；如果第二WiFi通路的链路质量要优于第一WiFi通路，则确定第二WiFi通路的数据包占比高于第一WiFi通路的数据包占比。举例来说，如果第一WiFi通路的链路质量为20、如果第二WiFi通路的链路质量为80，则第一WiFi通路与第二WiFi通路之间的数据包分配比例为2:8。
可选的，第一WiFi通路的链路质量可以基于第一WiFi通路的上下行数据传输速率、往返时延、丢包率、误码率来进行打分，得到第一WiFi通路的质量分。类似的，也可以得到第二WiFi通路的质量分。移动终端可以将第一WiFi通路的质量分与第二WiFi通路的质量分之比作为第一WiFi通路与第二WiFi通路之间的数据包分配比例。
可选的，移动终端也可以根据第一WiFi通路的质量分确定第一WiFi通路的质量等级，根据第二WiFi通路的质量分确定第二WiFi通路的质量等级，依据第一WiFi通路的质量等级、第二WiFi通路的质量等级来确定第一WiFi通路与第二WiFi通路之间的数据包分配比例。
例如，可以设置第一WiFi通路、第二WiFi通路的质量等级为I级、II级、III级、IV 级、V级这五个等级，分别代表链路质量很差、差、中等、良、优。I级、II级、III级、IV级、V级这五个等级分别对应质量分为：0～30、30～60、60～80、80～90、90～100。可以根据第一WiFi通路的质量等级与第二WiFi通路的质量等级之比来确定第一WiFi通路与第二WiFi通路之间的数据包分配比例。举例来说，如果第一WiFi通路的链路质量为I级，第二WiFi通路的链路质量为I级，则第一WiFi通路与第二WiFi通路之间的数据包分配比例为1:1；如果第一WiFi通路的链路质量为I级，第二WiFi通路的链路质量为IV级，则第一WiFi通路与第二WiFi通路之间的数据包分配比例为1:4。
可选的，移动终端检测第一WiFi通路的链路质量，检测第二WiFi通路的链路质量，具体可以包括如下步骤：
移动终端测量第一WiFi通路的最大数据传输速率，测量第二WiFi通路的最大数据传输速率，基于第一WiFi通路的最大数据传输速率和第二WiFi通路的最大数据传输速率确定第一WiFi通路的链路质量和第二WiFi通路的链路质量。
本申请实施例中，可以按照如下公式计算第一WiFi通路的链路质量和第二WiFi通路的链路质量：
weigh_wifi_1＝max_speed_wifi_1/(max_speed_wifi_1+max_speed_wifi_2)；
weigh_wifi_2＝max_speed_wifi_2/(max_speed_wifi_1+max_speed_wifi_2)；
其中，weigh_wifi_1表示第一WiFi通路的链路质量，weigh_wifi_2表示第二WiFi通路的链路质量，max_speed_wifi_1表示第一WiFi通路的最大数据传输速率，max_speed_wifi_2表示第二WiFi通路的最大数据传输速率。第一WiFi通路的链路质量与第二WiFi通路的链路质量之和等于1。
移动终端可以根据第一WiFi通路的链路质量与第二WiFi通路的链路质量之比确定第一WiFi通路与第二WiFi通路之间的数据包分配比例。
比如，第一WiFi通路的链路质量为0.3、第二WiFi通路的链路质量为0.7，则确定第一WiFi通路与第二WiFi通路之间的数据包分配比例为3:7。
可选的，第一WiFi通路的最大数据传输速率、第二WiFi通路的最大数据传输速率可以通过wifi的数据增量计算速率来进行修正。
比如，每隔1s统计第一wifi接收(rx)接口、第二wifi接收(rx)接口上的数据增量计算速率，通过数据增量计算速率对第一WiFi通路的最大数据传输速率、第二WiFi通路的最大数据传输速率进行修正。
tmp_speed＝(rx_bytes-last_rx_bytes)/1；
修正后的max_speed_wifi_1＝max(max_speed_wifi_1,tmp_speed)；
修正后的max_speed_wifi_2＝max(max_speed_wifi_2,tmp_speed)；
其中，rx_bytes表示一秒内第一wifi接口和第二wifi接口上的数据接收量，last_rx_bytes表示上一秒内第一wifi接口和第二wifi接口上的数据接收量，tmp_speed表示数据增量计算速率，max_speed_wifi_1表示第一WiFi通路的最大数据传输速率，max_speed_wifi_2表示第二WiFi通路的最大数据传输速率。修正后的max_speed_wifi_1为max_speed_wifi_1与tmp_speed中的最大值，修正后的max_speed_wifi_2为max_speed_wifi_2与tmp_speed中的最大值。
可选的，第一WiFi通路的最大数据传输速率以及第二WiFi通路的最大数据传输速率可以通过统计往返时延(Round-Trip Time，rtt)来进行修正。
比如，移动终端可以基于tcp协议本身的rtt，来计算两个接口(第一WiFi通信模块接口和第二WiFi通信模块接口)上的延时，一条数据链接只计算三次握手之后的第一个请求的rtt，比如http get，http post的rrt。3次握手指的是TCP建立连接的3个确认过程。传输控制协议(Transmission Control Protocol，tcp)通过tcp_rtt_estimator()函数来统计rtt进 而计算超时重传时间(Retransmission Timeout，RTO)，所以延时计算在tcp_rtt_estimator()函数中计算。
移动终端分别确定第一WiFi通路的当前的第一RTT、第二WiFi通路的当前的第一RTT，包括：
移动终端确定运行一个传输控制协议TCP的第二RTT；
移动终端分别获取第一WiFi通信模块、第二WiFi通信模块上一次确定的第三RTT；
移动终端根据确定的所述第二RTT和获取的第一WiFi通信模块、第二WiFi通信模块上一次确定的第三RTT确定所述第一WiFi通信模块、第二WiFi通信模块当前的第一RTT。
具体的，可以采用如下公式计算第一WiFi通路的当前的第一RTT、第二WiFi通路的当前的第一RTT：
rtt_wifi_11＝(rtt_wifi_13+rtt_2)/2
rtt_wifi_21＝(rtt_wifi_23+rtt_2)/2
其中，rtt_wifi_11表示第一WiFi通路的当前的第一RTT，rtt_2表示运行一个传输控制协议TCP的第二RTT，rtt_wifi_13表示第一WiFi通路的上一次确定的第三RTT；rtt_wifi_21表示第二WiFi通路的当前的第一RTT，rtt_2表示运行一个传输控制协议TCP的第二RTT，rtt_wifi_23表示第二WiFi通路的上一次确定的第三RTT。
本申请实施例在计算WiFi通路的链路质量时充分考虑了数据传输速率和往返时延，可以提高第一WiFi通路与第二WiFi通路的链路质量的计算准确度。
可选的，步骤101中，移动终端基于接入点AP类型分流策略确定第一WiFi通路和第二WiFi通路之间的数据包分配比例，包括：
移动终端获取第一WiFi模块连接的AP的类型，获取第二WiFi模块连接的AP的类型；
移动终端根据第一WiFi模块连接的AP的类型确定第一WiFi模块连接的AP的安全性，根据第二WiFi模块连接的AP的类型确定第二WiFi模块连接的AP的安全性；
移动终端获取需要传输的数据包的类型，确定需要传输的数据包所需要的安全性要求，根据需要传输的数据包所需要的安全性要求、第一WiFi模块连接的AP的安全性、第二WiFi模块连接的AP的安全性确定第一WiFi通路和第二WiFi通路之间的数据包分配比例。
本申请实施例中，不同的AP的安全性是不同的，比如，家庭AP、公共场所AP、手机热点AP等，移动终端可以检测第一WiFi模块连接的AP的安全性、第二WiFi模块连接的AP的安全性。
移动终端根据需要传输的数据包所需要的安全性要求、第一WiFi模块连接的AP的安全性、第二WiFi模块连接的AP的安全性确定第一WiFi通路和第二WiFi通路之间的数据包分配比例，具体可以为：
移动终端确定第一WiFi模块连接的AP的安全性为第一安全等级、确定第二WiFi模块连接的AP的安全性为第二安全等级，其中，第一安全等级的安全性大于第二安全等级的安全性。若需要传输的数据包包括第一数据包和第二数据包，第一数据包的安全性要求为第一安全等级，第二数据包的安全性要求为第二安全等级，则将需要传输的数据包中的第一数据包分配在第一WiFi通路中传输，将需要传输的数据包中的第二数据包分配在第二WiFi通路中传输。本申请实施例可以根据需要传输的数据包所需要的安全性要求、第一WiFi模块连接的AP的安全性、第二WiFi模块连接的AP的安全性确定第一WiFi通路和第二WiFi通路之间的数据包分配比例，满足不同安全性要求的数据包的分流传输需求，可以在提高数据传输量的同时提高数据包传输的安全性。
请参阅图2，图2是本申请实施例公开的另一种基于双WiFi模块的数据分流方法的流程示意图，如图2所示，该基于双WiFi模块的数据分流方法包括如下步骤。
201，移动终端接收用户输入的双WiFi模式启动指令，启动双WiFi模式；或者，移动 终端确定是否符合双WiFi启动条件，若符合，启动双WiFi模式。
本申请实施例中，双WiFi模式的启动可以由用户触发，也可以由移动终端自行触发。移动终端可以基于用户主动交互设置启用双WiFi模式。比如，用户可以在移动终端的用户设置界面中选择是否启动双WiFi模式。移动终端可以自行触发双WiFi模式。比如，移动终端基于当前网络质量/信号强度而启用双WiFi；基于场景识别确定用户针对智能家居的控制需求而启用双WiFi模式；基于针对视频等特定应用的投屏操作等启用双WiFi模式。本申请实施例可以提供两种双WiFi模式启动方式，可以灵活的进入双WiFi模式。
可选的，步骤201中，移动终端接收用户输入的双WiFi模式启动指令，启动双WiFi模式，包括：
在单WiFi模式下，第一WiFi模块连接第一频段AP，若移动终端接收到用户针对第二频段AP的接入请求，移动终端将二WiFi模块连接第二频段AP，关闭单WiFi模式，启动双WiFi模式。
本申请实施例中，移动终端在进入双WiFi模式之前，可以为单WiFi模式，也即，移动终端的第一WiFi模块连接第一频段AP，移动终端已经建立了第一WiFi通路，可以通过第一WiFi通路上网。此时，如果移动终端接收到用户针对第二频段AP的接入请求，移动终端将二WiFi模块连接第二频段AP，关闭单WiFi模式，启动双WiFi模式。举例来说，用户可以在用户设置界面搜索可用热点(即，可用AP)，如果可用AP列表中存在第二频段AP，用户点击某一个第二频段AP接入，即表明用户有接入双WiFi的需求，从而启动双WiFi模式。在该双WiFi模式下，第一WiFi模块连接第一频段AP，第二WiFi模块连接第二频段AP。本申请实施例无需断开单WiFi模式下连接的第一频段的AP，只需要在单WiFi模式的基础上将第二WiFi模块连接第二频段AP即可进入双WiFi模式，可以在单WiFi模式下通过用户交互快速进入双WiFi模式。
可选的，步骤201中，移动终端接收用户输入的双WiFi模式启动指令，启动双WiFi模式，包括：
在第一WiFi模块和第二WiFi模块均断开连接的情况下，若移动终端接收到用户输入的双WiFi模式启动请求，移动终端搜索并选择第一频段AP，将第一WiFi模块连接第一频段AP，搜索并选择第二频段AP，将第二WiFi模块连接第二频段AP。
本申请实施例中，移动终端在进入双WiFi模式之前，可以为无WiFi模式，也即，第一WiFi模块和第二WiFi模块均断开连接。此时，如果移动终端接收到用户输入的双WiFi模式启动请求，移动终端搜索并选择第一频段AP，将第一WiFi模块连接第一频段AP，搜索并选择第二频段AP，将第二WiFi模块连接第二频段AP。举例来说，用户可以在用户设置界面点击启动双WiFi模式的按钮，移动终端执行搜索并选择第一频段AP，将第一WiFi模块连接第一频段AP，搜索并选择第二频段AP，将第二WiFi模块连接第二频段AP的步骤。本申请实施例中，用户可以一键进入双WiFi模式，可以在没有任何WiFi模块连接的情况下通过用户交互快速进入双WiFi模式。
可选的，移动终端搜索并选择第一频段AP，包括：
移动终端搜索当前可用的第一频段AP列表，若当前可用的第一频段AP列表中存在历史连接的第一频段AP，移动终端从历史连接的第一频段AP中选择信号强度最高的AP。
移动终端搜索并选择第二频段AP，包括：
移动终端搜索当前可用的第二频段AP列表，若当前可用的第二频段AP列表中存在历史连接的第二频段AP，移动终端从历史连接的第二频段AP中选择信号强度最高的AP。
本申请实施例中，移动终端在搜索并选择AP(AP，可以理解为WiFi热点)时，可以选择历史连接的AP，并从历史连接的AP中选择信号强度最高的AP。由于历史连接的AP的连接过程无需手动进行密码验证，并且安全性已经得到验证，可以快速安全的进入双WiFi 模式。
可选的，步骤201中，移动终端确定是否符合双WiFi启动条件，包括：
在单WiFi模式下，第一WiFi模块连接第一频段AP，若当前下载速率需求大于第一频段AP提供的最大下载速率，或者当前上行速率需求大于第一频段AP提供的最大上行速率，移动终端搜索并选择第二频段AP，将第二WiFi模块连接第二频段AP。
本申请实施例中，在单WiFi模式下，可以根据目前的单WiFi模式下第一频段AP提供的最大下载/上行速率是否符合当前下载/上行速率需求决定是否选择启动双WiFi模式。当前下载/上行速率需求可以根据当前运行的业务类型来确定，不同的业务类型对下载/上行速率的需求不相同。业务类型可以包括：视频类业务、游戏类业务、语音类业务、即时通讯类业务等。比如，当前的业务类型为视频类业务时，对下载速率的需求较高，当前的业务类型为游戏类业务时，对上行速率的需求较高。本申请实施例可以根据当前下载速率需求选择是否开启双WiFi模式，可以在保证用户上网体验的前提下节省功耗。
可选的，步骤201中，移动终端确定是否符合双WiFi启动条件，包括：
移动终端检测指定类型应用是否启动，若是，则确定符合双WiFi启动条件。
本申请实施例中，由于某些类型的应用多网络速度要求较高，需要启动双WiFi模式才能满足，因此在某些指定类型应用开启时，如果当前不处于双WiFi模式，则确定符合双WiFi启动条件，启动双WiFi模式。指定类型应用可以是视频类应用、游戏类应用等。本申请实施例可以根据应用类型选择是否开启双WiFi模式，可以在保证应用使用体验的前提下节省功耗。
202，在双WiFi模式下，移动终端基于应用类型分流策略、数据包类型分流策略、链路质量分流策略、接入点AP类型分流策略中的至少一种分流策略确定第一WiFi通路和第二WiFi通路之间的数据包分配比例。
203，移动终端将需要传输的数据包按照数据包分配比例分配在第一WiFi通路和第二WiFi通路中传输。
本申请实施例中的步骤202和步骤203的具体实施可以参见图1所示的步骤101至步骤102，此处不再赘述。
本申请实施例中，采用双WiFi模块，双WiFi模块可以支持两条WiFi通路同时收发数据，移动终端可以将需要传输的数据包分配在第一WiFi通路和第二WiFi通路中传输，从而提高WiFi网络的数据传输量。同时支持手动和自动触发双WiFi模式，可以提供两种双WiFi模式启动方式，可以灵活的进入双WiFi模式。
