Description

一种多路HTTP通道复用的方法及终端

技术领域
本申请涉及通信技术领域，尤其涉及一种多路HTTP通道复用的方法及终端。
背景技术
多路超文本传输协议(Multipath Hypertext Transfer Protocol，MPHTTP)技术，可以实现终端与服务器之间多路HTTP通道同时传输数据，提升终端和服务器之间的数据传输效率。例如，用户在使用终端观看高清视频、VR资源等时，终端可以同时使用Wi-Fi网络和蜂窝网传输用户请求的数据，以提供更大的传输带宽，使得高清视频、VR资源等下载速率更快，用户观看时卡顿更少、更流畅。
现有技术中，接收用户操作应用程序的指示，终端根据用户的操作指示，生成原始的HTTP请求(request)。然后，据原始HTTP请求中携带的范围字节(range byte)字段，将原始HTTP请求拆分为多个HTTP请求。并分别在不同的HTTP通道中发送。这多个HTTP请求分别用于通过在不同的HTPP通道中请求原始HTTP请求中请求的不同字节范围的数据，即实现多路HTTP通道同时传输数据，提升数据传输的效率。
然而，在很多实际场景中，终端生成的原始的HTTP请求没有携带范围字节字段，那么，将无法实现多路HTTP通道的复用。

当用户在移动终端100上操作相应的应用时，移动终端会生成相应的第一HTTP请求，并将第一HTTP请求通过上述HTTP通道中的其中一个HTTP通道(记为第一HTTP通道)发送给相应的服务器。服务器在收到HTTP请求后，通过该第一HTTP通道向移动终端返回相应的第一HTTP响应(response)，以及返回移动终端100请求的数据(记为第一数据)。
在本申请的实施例中，在服务器通过第一HTTP通道发送第一HTTP响应后，开始向移动终端100发送第一数据。由于本申请实施例提供的多路HTTP通道复用的方法，会采用其他HTTP通道共同传输第一数据，故这里将服务器通过第一HTTP通道传输的数据记为第一数据中的第一部分。
为了实现多路HTTP通道复用，移动终端100在接收到的第一HTTP响应后，还要根据第一HTTP响应中包含的第一数据的大小(例如第一HTTP响应中的内容长度(content-length)字段)，生成至少一个第二HTTP请求，用于请求第一数据中的部分数据(可记为第一数据中固定第二部分)。然后，将至少一个第二HTTP请求通过除第一HTTP通道外的其他通道(记为第二HTTP通道)传输给服务器，服务器将在第二HTTP通道返回第一数据中的第二部分。也就是说，第一HTTP通道和第二HTTP通道共同完成移动终端本次请求的第一数据，增大了第一数据的传输带宽，提升数据传输的效率。

下面结合附图对本申请实施例提供的技术方案进行详细说明。
如图4所示，为本申请实施例提供的一种多路HTTP通道复用的方法的流程示意图，具体如下：
S401、移动终端通过第一HTTP通道向第一服务器发送第一HTTP请求，用于请求第一数据。
示例性的，移动终端上安装有应用程序，用户可以通过操作应用程序来指示移动终端从该应用程序对应的第一服务器处请求数据。结合图3所示的结构，以用户操作视频应用为例进行说明。例如，移动终端在接收到用户对视频应用中相关视频对应的播放控件的操作后，生成第一HTTP请求，用于请求从视频应用对应的第一服务器处获取该视频对应的第一数据。其中，视频应用可以采用HTTP1/1.1/HTTP2等协议进行通信。在一个具体的实现方式中，移动终端的视频应用将第一HTTP请求通过框架层的多路复用模块，以及内核层的TCP/IP协议栈、通过Modem驱动或Wi-Fi驱动，发送给第一服务器。
根据HTTP协议可知，第一HTTP请求中携带统一资源标识符(Uniform Resource Identifier，URI)或者统一资源定位符(Uniform Resource Locator，URL)，用于指示移动终端所请求第一数据在网络中的地址。在移动终端发送第一HTTP请求之前，移动终端可以通过第一HTTP通道发送域名系统(Domain Name System，DNS)请求(例如标准DNS请求或HTTP DNS请求)，用于解析得到存储第一数据的第一服务器的网络地址(IP地址)。而后，通过第一HTTP通道发送第一HTTP请求，向第一服务器请求第一数据。在一些示例中，第一HTTP请求中没有携带请求的第一数据的范围。例如第一HTTP请求中没有携带第一数据的范围字节(range byte，或range bytes，或range：bytes)字段。在这种情况下，便不能使用现有技术中基于第一数据的字节范围将第一HTTP请求拆分为多个HTTP请求，以实现多路HTTP通道的复用。然而，本申请实施例提供的方法可以实现多路HTTP通道的复用，具体可参考下文描述。
在本申请的一些实施例中，移动终端可以保存一份第一HTTP请求，以便后续根据该第一HTTP请求生成其他HTTP通道的HTTP请求时，可以直接使用第一HTTP请求中部分字段的值，例如URI或URL等。
在本申请的另一些实施例中，前文已说明，移动终端可以建立至少两路HTTP通道。移动终端可以从该至少两路HTTP通道中选择一条通道(例如预计的数据流完成时间(Flow completion time，FCT)最小的通道)作为第一HTTP通道，用于传输第一HTTP请求。这是因为，由于移动终端先通过第一HTTP通道传输第一HTTP请求， 接收第一HTTP响应以及接收第一数据中的部分内容。而后，在接收到第一HTTP响应后，才根据第一HTTP响应中的第一数据长度，请求其他HTTP通道开始传输第一数据中另外部分内容。可见，选择预计的FCT最小的通道先用于传输第一数据中的部分数据，有利于减小传输第一数据所耗用的时长，提升传输效率。
其中，预计的FCT可以包括第一HTTP通道建立连接耗用的时间，第一HTTP通道传输单位大小数据所耗用的时间，以及传输数据的时延等。可见，预计的FCT可以反映HTTP通道传输数据的速率和效率。具体的计算FCT的方法可以参考本领域技术中相关的算法，本申请实施例对此不做限定。
可选的，移动终端也可以基于其他原则选择该至少两路HTTP通道中的一条通道作为第一HTTP通道。例如，选择预设的HTTP通道作为第一HTTP通道，例如优先选择Wi-Fi通道。又例如，选择已建立好连接的HTTP通道作为第一HTTP通道。由于建立好连接的HTTP通道可以节省建立连接时的耗时，有利于提升传输第一数据的效率。
S402、移动终端通过第一HTTP通道接收第一服务器发送的第一HTTP响应，第一HTTP响应包括第一数据的大小。
根据HTTP协议可知，第一HTTP响应中携带将要返回数据的长度，即第一数据的大小。例如，第一HTTP响应中内容长度(content length)字段的值。
S403、在接收到第一HTTP响应后，移动终端通过第一HTTP通道接收第一服务器发送的第一数据的第一部分。
在接收到第一HTTP响应后，一方面，移动终端就可以开始接收第一服务器通道第一HTTP通道发送的第一数据。需要说明的是，由于本申请实施例，后续可能会调用其他HTTP通道共同传输第一数据。故，将通过第一HTTP通道传输的第一数据的部分数据记为第一数据的第一部分。另一方面，移动终端可以根据接收到的第一HTTP响应，获取第一数据的大小，并根据第一数据的大小判断是否需要使用多路HTTP通道共同传输第一数据。
示例性的，请继续参见图3所示的结构，移动终端通过Wi-Fi链路或蜂窝网链路接收到第一HTTP响应后，可将第一HTTP响应上传到多路复用模块。由多路复用模块确定是否需要使用多路通道传输第一数据。另一方面，多路复用模块将从第一HTTP通道接收到的第一数据的第一部分数据上传给上层的相应的应用，例如视频应用。
还需要说明的是，在一些示例中，第一HTTP响应中可能携带有第一数据的部分数据，则在下文根据第一数据的大小确定是否采用第二HTTP通道共同传输第一数据时，以及在二第二HTTP通道分配第一数据的第二部分时，所采用的第一数据的大小需要减去通过第一HTTP响应中已携带的第一数据的部分数据的大小。当然，第一HTTP响应中携带的第一数据的部分数据通常较小，也可以忽略该部分的数据大小。下文是以第一HTTP响应总不携带第一数据的部分数据，或者可以忽略第一HTTP响应中携带的第一数据中的部分数据为例进行说明的。
S404、若第一数据的大小大于第一阈值，则移动终端通过第二HTTP通道向第二服务器发送第二HTTP请求，用于请求第一数据中的第二部分。
其中，第二HTTP通道为与第一HTTP通道不同的HTTP通道。第二HTTP通道 的数量为至少一个。第二服务器与第一服务器可以为同一个服务器，也可以为不同的服务器。
若第一数据的大小小于或等于第一阈值，则认为移动终端仅使用第一HTTP通道传输第一数据即可，无需使用多路HTTP通道传输第一数据。若第一数据的大小大于第一阈值，则认为移动终端需要使用多路HTTP通道传输第一数据。在确定需要使用多路HTTP通道传输第一数据后，还需要确定每路HTTP通道用于传输第一数据的字节范围，即第一HTTP通道用于传输第一数据的字节范围(即第一部分的字节范围)，以及第二HTTP通道用于传输第一数据的字节范围(即第二部分的字节范围)。
需要注意的是，第一HTTP通道先开始接收第一数据的第一部分，第二HTTP通道后开始接收第一数据的第二部分。也就是说，应用在使用第一数据时，通常先使用第一数据的第一部分，而后使用第一数据的第二部分。也即，第一部分的字节范围通常为从第一数据的第一字节开始的。第二部分的字节范围通常为从中间的字节开始。例如，若采用两路HTTP通道复用传输第一数据，则第二部分的字节范围为从中间的字节开始，到第一数据的最后一个字节。
例如，第一数据为视频应用请求的视频数据，第一数据的第一部分可以包括时间靠前部分的视频数据，比如第0分钟起至第30分钟的视频数据。而第二数据可以为时间靠后部分的视频数据，比如第31分钟至45分钟的视频数据。那么，视频应用在使用第一数据时，需要先使用第一数据的第一部分，然后使用第一数据的第二部分。
其中，第一阈值的确定，以及确定第一数据的第一部分的字节范围和第二部分的字节范围的方法将下文详细说明，这里先不说明。
而后，移动终端可以根据保存的第一HTTP请求和确定的传输第二部分的字节范围，生成第二HTTP请求，向第一服务器请求在第二HTTP通道传输第一数据中的第二部分。在一个具体的实现中，移动终端可以在保存的第一HTTP请求中增加范围字节字段或者修改范围字节字段，写入第一数据中第二部分对应的字节范围；将保存的第一HTTP请求中host字段的值由第一服务器的地址修改为第二服务器的地址等，得到第二HTTP请求。然而在第二HTTP通道中发送第二HTTP请求，用于请求第二服务器通过第二HTTP通道返回第一数据的第二部分。
在另一些实施例中，在移动终端通过第二HTTP通道向第二服务器发送第二HTTP请求之前，可以根据保存的第一HTTP请求中的URI或URL，通过第二HTTP通道发送DNS请求，用于解析出第二服务器的IP地址。例如，移动终端可以在通过第一HTTP通道发送DNS请求(请求第一服务器的IP地址)时，提前通过第二HTTP通道发送DNS请求，用于请求第二服务器的IP地址。又例如，移动终端也可以在确定第一数据的大小大于第一阈值，确定需要使用第二HTTP通道发送第一数据时，再通过第二HTTP通道发送DNS请求，用于请求第二服务器的IP地址。本申请实施例对此不做限定。
一些示例中，移动终端可以在确定第一数据大于第一阈值后，开始建立第二HTTP通道的连接，通过第二HTTP通道传输第二HTTP请求以及接收第一数据的第二部分。这样，在需要第二HTTP通道传输数据才建立第二HTTP通道的连接，有利于节省移动终端的资源。在另一些示例中，移动终端也可以提前在接收到第一HTTP请求时， 提前建立第二HTTP通道的连接。当确定第一数据大于第一阈值后，可以直接使用第二HTTP通道传输第二HTTP请求。这样，有利于节省建立第二HTTP通道连接的时间，加快第一数据的传输速率。
S405、移动终端通过第二HTTP通道接收第二服务器返回的第一数据的第二部分。
由此实现了由第一HTTP通道和第二HTTP通道同时传输第一数据，提升了传输第一数据的带宽，加快了第一数据的下载速率。
在一些实施例中，第一服务器在通过第一HTTP通道传输第一数据的第一部分，以及第二服务器在通过第二HTTP通道传输第一数据的第二部部分时，均可以采用分块(chunk)传输的方法。也就是说，第一服务器将第一数据的第一部分又划分为多块，分次通过第一HTTP通道传输给移动终端。类似的，第二服务器也可以将第二数据的第二部分又划分为多块，分次通过第二HTTP通道传输给移动终端。由于在第一HTTP通道和第二HTTP通道同时传输第一数据时，移动终端可能交错接收到第一部分的分块和第二部分的分块。在该情况下，移动终端先使用第一部分的分块，再使用第二部分的分块。
示例性的，请继续参见图3所示的结构，移动终端通过Wi-Fi链路或蜂窝网链路接收到第一数据的分块后，可以确定接收到的第一数据的分块为第一部分的分块还是第二部分的分块。若该分块为第一部分的分块，则多路复用模块将该分块发送给请求第一数据的应用。若该分块为第二部分的分块，则多路复用模块缓存该分块。在确定将第一部分的所有分块都发送给请求第一数据的应用后，在将第二部分的分块发送给请求第一数据的应用。
在多路复用模块将接收到的第一数据的分块发送给请求第一数据的应用过程中，可以在第一个发送给应用的分块中携带第一HTTP响应的头部，后续在发送第一数据的其他分块给该应用是可不再携带第一HTTP响应的头部。
S406、在移动终端接收完第一数据的第一部分后，移动终端通过第一HTTP通道向第一服务器发送控制信令，与第一服务器断开第一HTTP通道。
示例性的，移动终端在确定接收完第一数据的第一部分后，需要通过第一HTTP通道向第一服务器发送控制信令，例如：HTTP RESET报文或TCP RESET报文，用于断开与第一服务器的第一HTTP通道。这是因为，第一服务器是根据移动终端发送的第一HTTP请求，向移动终端返回第一数据的。由于第一HTTP请求中未携带字节范围字段，第一服务器会依据协议将全部的第一数据返回给移动终端。然而，在本申请实施例中，第一数据的第二部分已经由第一服务器根据第二HTTP请求，通过第二HTTP通道返回给移动终端。因此，在移动终端确定接收完第一数据的第一部分后，需要断开与第一服务器的第一HTTP通道，不再通过第一HTTP通道接收第一数据的第二部分。
可选的，若移动终端通过第一HTTP通道向第一服务器发送TCP RESET报文，则移动终端会释放与第一HTTP通道的TCP连接。而后，移动终端也可以重启建立移动终端与第一服务器的HTTP通道的连接，便于后续移动终端继续通过第一HTTP通道的连接传输其他HTTP请求以及相应的数据。
需要说明的是，移动终端是通过第二HTTP请求在第二HTTP通道向第二服务器 请求第一数据的第二部分。由于第二HTTP请求中携带有请求的第二部分的字节范围，因此，第二服务器只会向移动终端返回第一数据的第二部分。
下面，以两路HTTP通道复用，且在确定第一数据大于第一阈值后才建立第二HTTP通道的连接为例，对本申请实施例中的第一阈值，以及确定第一部分字节范围和第二部分字节范围的方法进行示例性说明。
方法一、第一HTTP通道和第二HTTP通道同时完成数据传输。
步骤1、第一阈值的设置。
可以根据第一数据的大小、第一HTTP通道的带宽以及往返时延(Round-Trip Time，RTT)、第二HTTP通道的带宽以及往返时延确定第一阈值。
例如：假设仅使用第一HTTP通道(例如Wi-Fi通道)传输第一数据，计算预计的FCT1。
FCT1＝V1/BDW(A)                 (公式1)
其中，V1为第一数据的大小，BDW(A)为第一HTTP通道的带宽。
假设使用两路通道传输第一数据。例如，其中一路为Wi-Fi通道，另一路为蜂窝网通道，例如LTE，计算预计的FCT2。
FCT2＝2RTT(B)+V2/(c*SUM(BDW))  (公式2)
V2＝V1-2RTT(B)*BDW(A)          (公式3)
其中，SUM(BDW)＝BDW(A)+BDW(B)，其中，BDW(B)为第二HTTP通道的带宽。RTT(B)，为第二HTTP通道的往返时延。C为损失比例，例如可以取0.75。V2为第二HTTP通道连接建立后，两路HTTP通道共同传输的数据的大小。
需要说明的是，移动终端先建立第一HTTP通道连接，后建立第二HTTP通道连接。也就是说，在移动终端建立第二HTTP通道连接时，第一HTTP通道已经开始传输第一数据了。也就是说，在建立第二HTTP通道连接时，第一HTTP通道传输的数据的大小为2RTT(B)*BDW(A)。
另外，为了达到让第一HTTP通道和第二HTTP通道传输第一数据的效率最高，可以假设第一HTTP通道和第二HTTP通道同时传输完相应的数据。即，第一HTTP通道和第二HTTP通道传输完V2的数据共耗时V2/(c*SUM(BDW))。
结合公式1、公式2和公式3，令FCT1＝FCT2即可计算出V1的数值，即为第一阈值。
例如，假设RTT(A)＝RTT(B)＝70ms，BDW(A)＝24Mbps，BDW(B)＝24Mbps，可计算出第一阈值为1.6MB。也就是说，在该示例中，若待传输的第一数据大于1.6MB，则适用两路HTTP通道传输。若带传输的第一数据小于或等于1.6MB，则不使用两路HTTP通道进行传输。
还需要说明的是，这里是以先建立第一HTTP通道的连接，在确定第一数据的大小大于第一阈值后才开始建立第二HTTP通道的方法为例，说明第一阈值的确定的方法。若在确定第一数据的大小大于第一阈值之前提前建立好第二HTTP通道的连接，则公式2变为公式2A，如下：
FCT2＝V1/(c*SUM(BDW))            (公式2A)
结合公式1和公式2A，令FCT1＝FCT2，即可计算出V1的数值，即为提前建立第 二HTTP通道连接的方法中的第一阈值。
步骤2、确定每路HTTP通道传输的字节范围。
假设第一数据的大小为V1，需要第一HTTP通道传输的第一部分的数据大小为V(A)。需要第二HTTP通道传输的第二部分的数据大小为V(B)，那么，
V1＝V(A)+V(B)                   (公式4)
预计第一HTTP通道传输完V(A)的数据所需要的时间FCT(A)为：
FCT(A)＝V(A)/BDW(A)          (公式5)
预计第二HTTP通道传输完V(B)的数据所需要的时间FCT(B)为：
FCT(B)＝V(B)/BDW(B)            (公式6)
由上分析可知，第一HTTP通道在第二HTTP通道建立连接时以开始传输第一数据，且与第二HTTP通道同时结束数据传输，故FCT(A)和FCT(B)具备如下关系：
FCT(A)＝FCT(B)+2RTT(B)        (公式7)
结合上述公式4至公式7可以计算出，V(A)和V(B)。
因此，可以确定第一HTTP通道需要传输的第一数据的第一部分的字节范围为：0字节至V(A)字节。确定第二HTTP通道需要传输的第一数据的第二部分的字节范围为：{V(A)+1}字节至V1字节。或者，确定第一HTTP通道需要传输的第一数据的第一部分的字节范围为：0字节至{V(A)-1}字节。确定第二HTTP通道需要传输的第一数据的第二部分的字节范围为：V(A)字节至V1字节。
在该技术方案中，两路HTTP通道预计同时传输完相应的数据，传输效率最高。
还需要说明的是，这里是以先建立第一HTTP通道的连接，在确定第一数据的大小大于第一阈值后才开始建立第二HTTP通道的方法为例，说明第一阈值的确定的方法。若在确定第一数据的大小大于第一阈值之前提前建立好第二HTTP通道的连接，则结合公式4和公式6，令FCT(A)＝FCT(B)，即可计算出V(A)和V(B)。
在另一些示例中，若移动终端可以支持两路以上的HTTP通道复用时，还可以进一步确定V(A)和V(B)是否大于第一阈值。若任一个大于第一阈值，还可以采用类似的方法进行划分，使得两路以上的HTTP共同传输第一数据，进一步增大第一数据的传输带宽，提升第一数据的传输效率。当然，也可以采用方法一类似的方法，直接以两路以上的HTTP通道(例如三路HTTP通道)共同传输第一数据的场景，确定出第一阈值的大小，并确定两路以上的HTTP通道分别应传输多大的数据。本申请实施例对此不做限定。
方法二、第一HTTP通道和第二HTTP通道可以不同时传输完。
步骤1、确定第一阈值。
若仅采用第一HTTP通道传输第一数据的时长大于第二HTTP通道建立连接的时长下，可以确定采用两路HTTP通道进行传输第一数据。
其中，假设仅使用第一HTTP通道传输第一数据，计算预计的FCT1。
FCT1＝V1/BDW(A)                                         (公式4)
第二HTTP建立连接的耗时为：T(B)＝1.5RTT(B)+RTT(B)             (公式5)
令FCT1≥T(B)，结合公式4和公式5可计算得到V1的最小值，即为第一阈 值。
步骤2、确定每路HTTP通道传输的字节范围。
在确定每路HTTP通道传输的字节范围时，需要考虑以下因素：
因素1、预计第一HTTP通道不晚于第二HTTP通道传输完第一数据的第一部分。
由于在本申请实施例中，第一HTTP通道先用于传输第一数据的第一部分，第一部分通常为第一数据中字节靠前的部分数据。也就是说，移动终端通常会使用第一数据的第一部分，然后再使用第一数据的第二部分。因此，在设置每路HTTP通道传输的字节范围时，需要考虑第一HTTP通道能够不晚于第二HTTP通道传输完第一数据的第一部分。
因素2、预计多路HTTP通道共同传输完第一数据的时长小于使用任一路HTTP通道传输第一数据的时长。
由于，不同的HTTP通道的传输速率不同，不合理的字节范围的分配，可能会造成多路HTTP通道共同传输第一数据的总时长会大于单独使用最大传输速率的HTTP通道传输第一数据。因此，在设置每路HTTP通道传输的字节范围时，需要结合每路HTTP通道的传输速率，使得多路HTTP通道共同传输完第一数据的时长小于使用任一路HTTP通道传输第一数据的时长。
在另一些示例中，与方法一类似的，若移动终端可以支持两路以上的HTTP通道复用时，还可以进一步分别确定分配给两路HTTP通道的数据量是否大于第一阈值。若任一个大于第一阈值，还可以采用方法二类似的方法进行划分，使得两路以上的HTTP通道共同传输第一数据，进一步增大第一数据的传输带宽，提升第一数据的传输效率。当然，也可以采用方法二类似的方法，直接以两路以上的HTTP通道(例如三路HTTP通道)共同传输第一数据的场景，确定出第一阈值的大小，并确定两路以上的HTTP通道分别应传输多大的数据。本申请实施例对此不做限定。
需要说明的是，上述方法一和方法二为基于本申请实施例提供的多路复用的发明构思，提供的两种设置第一阈值，以及确定每路HTTP通道传输第一数据的字节范围的方法示例。当然，也可以基于实际的场景采用不同的第一阈值以及确定每路HTTP通道传输的字节范围的方法，本申请实施例对此不做限定。
下面结合图5，以移动终端是手机为例，对本申请实施例提供的方法的应用场景进行示例性说明。
如图5中(1)所示，为手机视频应用的一个视频浏览界面501。可以理解的是，视频应用需要上网，故手机之前至少开启了Wi-Fi功能或者蜂窝网流量功能。这里以手机开启了Wi-Fi功能为例进行说明。响应于检测到用户点击某个视频对应的控件的操作，视频应用生成第一HTTP请求，并通过已建立好的Wi-Fi链路发送给服务器，用于请求该视频的数据(即第一数据)。在接收到服务器返回的第一HTTP响应时，手机根据第一HTTP响应中携带的该视频的数据大小(例如，为10000字节)确定是否大于阈值。若大于第一阈值，手机确定需要使用多路HTTP通道共同传输第一数据。在一些示例中，手机可以显示如图5中(2)所示的界面502。界面502中显示有提示信息503，用于询问用户是否确定使用蜂窝网流量。若用户确定使用蜂窝网流量，则手机根据保存的第一HTTP请求和第一HTTP响应中携带的请求数据的大小，生成第 二HTTP请求。例如，第二HTTP请求中携带的请求第一数据的字节范围为5000字节至10000字节。手机将第二HTTP请求通过蜂窝网链路发送给服务器，请求第一数据的5000字节至10000字节。也就是说，手机通过Wi-Fi链路接收第一数据的0-4999字节的同时，也通过蜂窝网链路接收第一数据的5000-10000字节。手机根据接收到已接收到的第一数据播放视频，即显示如图5中(4)所示的视频播放界面504。
在又一些示例中，在手机确定第一HTTP响应中携带的该视频的数据大小确定大于第一阈值时，若检测到用户未开启蜂窝网流量功能，例如显示如图5中(3)所示界面505。界面505中的包括提示信息506，用于提示用户开启蜂窝网流量功能。
以上实施例中，是以移动终端使用确定的第一阈值，来判断是否采用第二HTTP通道共同传输数据为例进行说明的。在本申请的又一些实施例中，移动终端也可以采用自学习的方法，来判断是否采用第二HTTP通道共同传输数据，以及各个HTTP通道分别承担多大数据量的传输。
示例性的，在移动终端请求第一数据时，移动终端可以默认采用第一HTTP通道和第二HTTP通道，共同接收第一数据。并且，默认设置通过第二HTTP通道接收第一数据的第二部分的数据大小占据第一数据大小的比例(例如第一比例)。当然也可默认设置通过第一HTTP通道接收第一数据的第一部分的数据大小占第一数据大小的比例。或者，默认设置通过第一HTTP通道接收第一数据的第一部分的数据大小与通过第二HTTP通道接收第一数据的第二部分的数据大小的比例。本申请对设置的比例不做具体限定。下文以设置通过第二HTTP通道接收第一数据的第二部分的数据大小占据第一数据大小的比例为例进行说明。
后续，当移动终端需要接收第二数据时，则根据第一HTTP通道接收第一数据的第一部分耗用的时长，以及第二HTTP通道接收第一数据的第二部分耗用的时长，自动调整第二HTTP通道传输第二数据的第二部分的数据大小占据第二数据大小的比例。以此类推，第一HTTP通道和第二HTTP通道传输其他数据的比例可调整到合适比例，从而提升第一HTTP通道和第二HTTP通道传输数据的效率。
例如，这里以移动终端提前建立好第一HTTP通道和第二HTTP通道的连接为例进行说明。如果第一HTTP通道传输第一数据第一部分耗用的时长大于第二HTTP通道传输第一数据第二部分耗用的时长，则可认为第一HTTP通道传输效率低于第二HTTP通道，则可以适当增大第一比例，即适当增加第二HTTP通道传输第二数据第二部分占据第二数据的比例。这样，可以提升传输第二数据的传输效率。
如果第一HTTP通道传输第一数据第一部分耗用的时长小于第二HTTP通道传输第一数据第二部分耗用的时长，则可认为第一HTTP通道传输效率高于第二HTTP通道，则可以适当减小第一比例，即适当减小第二HTTP通道传输第二数据第二部分占据第二数据的比例。这样，可以提升传输第二数据的传输效率。
如果第一HTTP通道传输第一数据第一部分耗用的时长等于(或者大致等于)第二HTTP通道传输第一数据第二部分耗用的时长，则可认为第一HTTP通道传输效率和第二HTTP通道相同，则可以保持第一比例，即保持第二HTTP通道传输第二数据第二部分占据第二数据的比例。
再例如，这里以移动终端也可以在确定使用第二HTTP通道时，才建立第二HTTP 通道的连接为例进行说明。如果第一HTTP通道传输第一数据第一部分耗用的时长减去第二HTTP通道传输第一数据第二部分耗用的时长的差值大于第二阈值(例如第二阈值包括第二HTTP建立连接耗用的时间)，则可认为第一HTTP通道传输效率低于第二HTTP通道，则可以适当增大第一比例，即适当增加第二HTTP通道传输第二数据第二部分占据第二数据的比例。这样，可以提升传输第二数据的传输效率。
如果第一HTTP通道传输第一数据第一部分耗用的时长减去第二HTTP通道传输第一数据第二部分耗用的时长的差值小于第二阈值，则可认为第一HTTP通道传输效率高于第二HTTP通道，则可以适当减小第一比例，即适当减小第二HTTP通道传输第二数据第二部分占据第二数据的比例。这样，可以提升传输第二数据的传输效率。
如果第一HTTP通道传输第一数据第一部分耗用的时长减去第二HTTP通道传输第一数据第二部分耗用的时长的差值等于或大致等于第二阈值，则可认为第一HTTP通道传输效率和第二HTTP通道相同，则可以保持第一比例，即保持第二HTTP通道传输第二数据第二部分占据第二数据的比例。这样，可以提升传输第二数据的传输效率。
本申请实施例还提供一种芯片系统，如图6所示，该芯片系统包括至少一个处理器1101和至少一个接口电路1102。处理器1101和接口电路1102可通过线路互联。例如，接口电路1102可用于从其它装置(例如移动终端100的存储器)接收信号。又例如，接口电路1102可用于向其它装置(例如处理器1101)发送信号。示例性的，接口电路1102可读取存储器中存储的指令，并将该指令发送给处理器1101。当所述指令被处理器1101执行时，可使得移动终端执行上述实施例中的移动终端100(比如，手机)执行的各个步骤。当然，该芯片系统还可以包含其他分立器件，本申请实施例对此不作具体限定。
