Wherein, by splitting the size of the first data to be acquired between the LTE network and the WiFi network based on the first transmission rate and the second transmission rate, it is possible to make full use of the characteristics of the LTE network and the WiFi network, and realize an optimized splitting method .

需要说明的是，LTE网络和WiFi网络的特性分别是：LTE网络的速度较快，但是价格相对昂贵，WiFi网络完全免费，但是速度较慢。本发明实施例中基于TCP流的业务量(即第一数据的大小)将TCP流进行拆分，使得对于同一个TCP流，能够同时使用到LTE网络和WiFi网络，兼顾了速度及价格的考虑，实现了数据的优化分流。It should be noted that the characteristics of the LTE network and the WiFi network are respectively: the speed of the LTE network is faster, but the price is relatively expensive, and the WiFi network is completely free, but the speed is relatively slow. In the embodiment of the present invention, the TCP flow is split based on the traffic volume of the TCP flow (that is, the size of the first data), so that the same TCP flow can be used simultaneously on the LTE network and the WiFi network, taking into account the considerations of speed and price , which realizes the optimized distribution of data.

请参阅图5，为本发明图3所示第一实施例中划分模块302的细化功能模块的示意图，该划分模块302包括：第一确定模块501及第二确定模块502。Please refer to FIG. 5 , which is a schematic diagram of the detailed functional modules of the division module 302 in the first embodiment shown in FIG. 3 of the present invention. The division module 302 includes: a first determination module 501 and a second determination module 502 .

第一确定模块501，用于根据LTE网络的第一传输速率、WiFi网络的第二传输速率及预置的时延确定第一数据的大小的分配比例；The first determination module 501 is configured to determine the distribution ratio of the size of the first data according to the first transmission rate of the LTE network, the second transmission rate of the WiFi network, and the preset time delay;

第二确定模块502，用于按照分配比例划分第一数据的大小，确定通过LTE网络传输的第二数据的大小及通过WiFi网络传输的第三数据的大小。The second determination module 502 is configured to divide the size of the first data according to the distribution ratio, and determine the size of the second data transmitted through the LTE network and the size of the third data transmitted through the WiFi network.

在本发明实施例中，移动终端将监测LTE网络的第一传输速率及WiFi网络的第二传输速率，且在接收到服务器反馈的第一数据的大小之后，获取当前的第一传输速率及第二传输速率，并由第一确定模块501根据第一传输速率、第二传输速率及预置的时延确定第一数据的大小的分配比例。In the embodiment of the present invention, the mobile terminal will monitor the first transmission rate of the LTE network and the second transmission rate of the WiFi network, and obtain the current first transmission rate and the second transmission rate after receiving the size of the first data fed back by the server. Two transmission rates, and the allocation ratio of the size of the first data is determined by the first determination module 501 according to the first transmission rate, the second transmission rate and the preset time delay.

具体的，第一确定模块502可以按照如下公式(1)或者公式(2)确定分配比例：Specifically, the first determination module 502 may determine the distribution ratio according to the following formula (1) or formula (2):

$\frac{RC}{V_W}=\frac{(1-R)C}{V_L}+t$公式(1)$\frac{RC}{V_W}=\frac{(1-R)C}{V_L}+t$ Formula 1)

$R=\frac{V_{W}C+V_W{V}_{L}t}{(V_L+V_W)C}=\frac{C+V_{L}t}{(1+V_L/V_W)C}$公式(2)$R=\frac{V_{W}C+V_W{V}_{L}t}{(V_L+V_W)C}=\frac{C+V_{L}t}{(1+V_L/V_W)C}$ Formula (2)

在上述公式(1)和公式(2)中：R表示通过WiFi网络传输的第三数据占第一数据的百分比，C表示第一数据的大小，V_W表示WiFi网络的第二传输速率，V_L表示LTE网络的第一传输速率，t表示预置的时延，其中，分配比例包括R及1-R，且1-R表示通过LTE网络传输的第二数据占第一数据的百分比。In the above formula (1) and formula (2): R represents the percentage of the third data transmitted through the WiFi network to the first data, C represents the size of the first data, V_W represents the second transmission rate of the WiFi network, V_L represents the first transmission rate of the LTE network, t represents the preset delay, wherein the allocation ratio includes R and 1-R, and 1-R represents the percentage of the second data transmitted through the LTE network to the first data.

在本发明实施例中，由于LTE网络的传输速度较快，因此，从公式(1)中可以看出：在大多数情况下，移动终端将先接收到通过LTE网络传输的第二数据，且在经过t秒的时延之后，接收到通过WiFi网络传输的第三数据，并将第二数据及第三数据合并成第一数据，其中，对于不同的应用层业务，t可以是不同的，例如对于语音等实时性较高的业务，t的取值较小，对于文件下载等一类的业务，t的取值较大。需要说明的是，移动终端可以基于当前的业务的类型获取该业务的类型对应的预置的时延t。In the embodiment of the present invention, since the transmission speed of the LTE network is relatively fast, it can be seen from the formula (1): in most cases, the mobile terminal will first receive the second data transmitted through the LTE network, and After a time delay of t seconds, the third data transmitted through the WiFi network is received, and the second data and the third data are combined into the first data, wherein, for different application layer services, t can be different, For example, for services with high real-time characteristics such as voice, the value of t is small, and for services such as file downloading, the value of t is relatively large. It should be noted that the mobile terminal may obtain the preset time delay t corresponding to the type of the service based on the type of the current service.

从公式(2)中可以看出：在WiFi网络的速度越快(即V_W越大)，预置的时延t越大时，划分给WiFi网络传输的第三数据占第一数据的比例越大。It can be seen from the formula (2): when the speed of the WiFi network is faster (i.e., V_W is larger), and the preset time delay t is larger, the ratio of the third data assigned to the WiFi network transmission to the first data is bigger.

在本发明实施例中，第二确定模块502将按照得到的分配比例划分第一数据的大小，确定通过LTE网络传输的第二数据的大小及通过WiFi网络传输的第三数据的大小。In the embodiment of the present invention, the second determining module 502 divides the size of the first data according to the obtained distribution ratio, and determines the size of the second data transmitted through the LTE network and the size of the third data transmitted through the WiFi network.

在本发明实施例中，通过基于LTE网络的第一传输速率及WiFi网络的第二传输速率划分待传输的第一数据的大小，使得能够充分利用LTE网络和WiFi网络的特性，实现数据的优化分流。In the embodiment of the present invention, by dividing the size of the first data to be transmitted based on the first transmission rate of the LTE network and the second transmission rate of the WiFi network, the characteristics of the LTE network and the WiFi network can be fully utilized to realize data optimization shunt.

For example: the size of the second data is the data of the length 0~(1-R)C of the data corresponding to the resource address, and the size of the third data is the data of the length of (1-R)C~C of the data corresponding to the resource address, so , through the above manner, the sending of the data message request can be effectively realized.

步骤803、通过所述LTE网络向所述服务器发送包含所述第二数据的大小的第二数据请求报文，及通过所述WiFi网络向所述服务器发送包含所述第三数据的大小的第三数据请求报文，以通过分流的方式获取所述第一数据。Step 803: Send a second data request message containing the size of the second data to the server through the LTE network, and send a second data request message containing the size of the third data to the server through the WiFi network Three data request packets, to obtain the first data in a splitting manner.

在本发明实施例中，在得到需要通过LTE网络传输的第二数据的大小及通过WiFi网络传输的第三数据的大小之后，移动终端将通过LTE网络向服务器发送包含第二数据的大小的第二数据请求报文，及通过WiFi网络向服务器发送包含第三数据的大小的第三数据请求报文，以通过分流的方式获取第一数据。例如：若资源地址对应的第一数据的大小为100M，且确定的第二数据的大小为30M，第三数据的大小为70M，则将通过LTE网络从服务器获取资源地址的前30M的数据，及通过WiFi网络从服务器获取该资源地址后70M的数据。In the embodiment of the present invention, after obtaining the size of the second data to be transmitted through the LTE network and the size of the third data to be transmitted through the WiFi network, the mobile terminal will send the second data containing the size of the second data to the server through the LTE network. 2. A data request message, and sending a third data request message including the size of the third data to the server through the WiFi network, so as to obtain the first data in a split manner. For example: if the size of the first data corresponding to the resource address is 100M, and the size of the determined second data is 30M, and the size of the third data is 70M, then the first 30M data of the resource address will be obtained from the server through the LTE network, And the 70M data after obtaining the resource address from the server through the WiFi network.

在本发明实施例中，移动终端同时接入LTE网络和WiFi网络之后，在第一TCP流建立完成后，向服务器发送查询请求，以获取该第一TCP流待传输的第一数据的大小，且在接收到服务器反馈的该第一数据的大小之后，根据监测到的LTE网络的第一传输速率及WiFi网络的第二传输速率对该第一数据的大小进行划分，分别确定通过LTE网络传输的第二数据的大小及通过WiFi网络传输的第三数据的大小，并通过LTE网络向服务器发送包含第二数据的大小的第二数据请求报文，及通过WiFi网络向服务器发送包含第三数据的大小的第三数据请求报文，以通过分流的方式获取第一数据。其中，通过将待获取的第一数据的大小基于第一传输速率和第二传输速率在LTE网络和WiFi网络之间进行分流，使得能够充分利用LTE网络和WiFi网络的特性，实现优化的分流方式。In the embodiment of the present invention, after the mobile terminal accesses the LTE network and the WiFi network at the same time, after the first TCP flow is established, it sends a query request to the server to obtain the size of the first data to be transmitted by the first TCP flow, And after receiving the size of the first data fed back by the server, the size of the first data is divided according to the monitored first transmission rate of the LTE network and the second transmission rate of the WiFi network, and respectively determined to be transmitted through the LTE network.

需要说明的是，LTE网络和WiFi网络的特性分别是：LTE网络的速度较快，但是价格相对昂贵，WiFi网络完全免费，但是速度较慢。本发明实施例中基于TCP流的业务量(即第一数据的大小)将TCP流进行拆分，使得对于同一个TCP流，能够同时使用到LTE网络和WiFi网络，兼顾了速度及价格的考虑，实现了数据的优化分流。It should be noted that the characteristics of the LTE network and the WiFi network are respectively: the speed of the LTE network is faster, but the price is relatively expensive, and the WiFi network is completely free, but the speed is relatively slow. In the embodiment of the present invention, the TCP flow is split based on the traffic volume of the TCP flow (that is, the size of the first data), so that the same TCP flow can be used simultaneously on the LTE network and the WiFi network, taking into account the considerations of speed and price , which realizes the optimized distribution of data.

需要说明的是，移动终端通过LTE网络向服务器发送第二数据请求报文，及通过WiFi网络向服务器发送第三数据请求报文之后，服务器将基于该第二数据请求报文中包含的第二数据的大小获取第二数据，并通过LTE网络将该第二数据反馈给移动终端；及基于该第三数据请求报文中包含的第三数据的大小获取第三数据，且通过WiFi网络将该第三数据反馈给移动终端，移动终端在接收到第二数据及第三数据之后，将按照预置的顺序将第二数据及第三数据进行合并，以得到第一数据。It should be noted that, after the mobile terminal sends the second data request message to the server through the LTE network, and sends the third data request message to the server through the WiFi network, the server will based on the second data request message contained in the second data request message Obtaining the second data according to the size of the data, and feeding back the second data to the mobile terminal through the LTE network; and obtaining the third data based on the size of the third data contained in the third data request message, and passing the second data through the WiFi network The third data is fed back to the mobile terminal, and after receiving the second data and the third data, the mobile terminal combines the second data and the third data in a preset order to obtain the first data.

其中，多链路至少包含一条LTE网络的链路和一条WiFi网络的链路，本发明实施例中是以一条LTE网络的链路和一条WiFi网络的链路为例的。在图4中，基站和WiFi热点通过核心网络经由路由器，连接到服务器。其中，1表示建立的第一TCP流的第一数据，“拆分”是指将第一数据的大小拆分为第二数据的大小和第三数据的大小，从用户侧(移动终端侧)指向服务器侧的1-1表示通过WiFi网络向服务器发送第二数据请求报文，从服务器侧指向用户侧的1-1表示服务器基于第二数据请求报文反馈的第二数据，从用户侧指向服务器侧的1-2表示通过LTE网络向服务器发送第三数据请求报文，从服务器侧指向用户侧的1-2表示服务器基于第三数据请求报文反馈的第三数据。且用户侧在接收到服务器反馈的1-1和1-2之后，将通过合并的方式得到第一数据，即2。Wherein, the multi-link includes at least one link of the LTE network and one link of the WiFi network.

In Figure 4, the base station and the WiFi hotspot are connected to the server through the core network via a router. Wherein, 1 represents the first data of the first TCP flow of setting up, and " splitting " refers to splitting the size of the first data into the size of the second data and the size of the third data, from the user side (mobile terminal side) 1-1 pointing to the server side indicates that the second data request message is sent to the server through the WiFi network, and 1-1 pointing from the server side to the user side indicates the second data fed back by the server based on the second data request message, pointing to 1-2 on the server side indicates that the third data request message is sent to the server through the LTE network, and 1-2 from the server side to the user side indicates the third data fed back by the server based on the third data request message. And after receiving 1-1 and 1-2 fed back by the server, the user side will obtain the first data, ie, 2, in a combined manner.

请参阅图9，为本发明图8所示第三实施例中步骤802的细化步骤的流程示意图，该细化步骤包括：Please refer to FIG. 9, which is a schematic flow chart of the refinement steps of step 802 in the third embodiment shown in FIG. 8 of the present invention, and the refinement steps include:

步骤901、根据所述LTE网络的第一传输速率、所述WiFi网络的第二传输速率及预置的时延确定第一数据的大小的分配比例；Step 901. Determine the distribution ratio of the size of the first data according to the first transmission rate of the LTE network, the second transmission rate of the WiFi network and the preset time delay;

步骤902、按照所述分配比例划分所述第一数据的大小，确定通过所述LTE网络传输的第二数据的大小及通过所述WiFi网络传输的第三数据的大小。Step 902: Divide the size of the first data according to the distribution ratio, and determine the size of the second data transmitted through the LTE network and the size of the third data transmitted through the WiFi network.

在本发明实施例中，移动终端将监测LTE网络的第一传输速率及WiFi网络的第二传输速率，且在接收到服务器反馈的第一数据的大小之后，获取当前的第一传输速率及第二传输速率，并根据第一传输速率、第二传输速率及预置的时延确定第一数据的大小的分配比例。In the embodiment of the present invention, the mobile terminal will monitor the first transmission rate of the LTE network and the second transmission rate of the WiFi network, and obtain the current first transmission rate and the second transmission rate after receiving the size of the first data fed back by the server. Two transmission rates, and determine the distribution ratio of the size of the first data according to the first transmission rate, the second transmission rate and the preset time delay.

具体的，移动终端可以按照如下公式(1)或者公式(2)确定分配比例：Specifically, the mobile terminal may determine the allocation ratio according to the following formula (1) or formula (2):

$\frac{RC}{V_W}=\frac{(1-R)C}{V_L}+t$公式(1)$\frac{RC}{V_W}=\frac{(1-R)C}{V_L}+t$ Formula 1)

$R=\frac{V_{W}C+V_W{V}_{L}t}{(V_L+V_W)C}=\frac{C+V_{L}t}{(1+V_L/V_W)C}$公式(2)$R=\frac{V_{W}C+V_W{V}_{L}t}{(V_L+V_W)C}=\frac{C+V_{L}t}{(1+V_L/V_W)C}$ Formula (2)

在上述公式(1)和公式(2)中：R表示通过WiFi网络传输的第三数据占第一数据的百分比，C表示第一数据的大小，V_W表示WiFi网络的第二传输速率，V_L表示LTE网络的第一传输速率，t表示预置的时延，其中，分配比例包括R及1-R，且1-R表示通过LTE网络传输的第二数据占第一数据的百分比。In the above formula (1) and formula (2): R represents the percentage of the third data transmitted through the WiFi network to the first data, C represents the size of the first data, V_W represents the second transmission rate of the WiFi network, V_L represents the first transmission rate of the LTE network, t represents the preset delay, wherein the allocation ratio includes R and 1-R, and 1-R represents the percentage of the second data transmitted through the LTE network to the first data.

在本发明实施例中，由于LTE网络的传输速度较快，因此，从公式(1)中可以看出：在大多数情况下，移动终端将先接收到通过LTE网络传输的第二数据，且在经过t秒的时延之后，接收到通过WiFi网络传输的第三数据，并将第二数据及第三数据合并成第一数据，其中，对于不同的应用层业务，t可以是不同的，例如对于语音等实时性较高的业务，t的取值较小，对于文件下载等一类的业务，t的取值较大。需要说明的是，移动终端可以基于当前的业务的类型获取该业务的类型对应的预置的时延t。In the embodiment of the present invention, since the transmission speed of the LTE network is relatively fast, it can be seen from the formula (1): in most cases, the mobile terminal will first receive the second data transmitted through the LTE network, and After a time delay of t seconds, the third data transmitted through the WiFi network is received, and the second data and the third data are combined into the first data, wherein, for different application layer services, t can be different, For example, for services with high real-time characteristics such as voice, the value of t is small, and for services such as file downloading, the value of t is relatively large. It should be noted that the mobile terminal may obtain the preset time delay t corresponding to the type of the service based on the type of the current service.

从公式(2)中可以看出：在WiFi网络的速度越快(即V_W越大)，预置的时延t越大时，划分给WiFi网络传输的第三数据占第一数据的比例越大。It can be seen from the formula (2): when the speed of the WiFi network is faster (i.e., V_W is larger), and the preset time delay t is larger, the ratio of the third data assigned to the WiFi network transmission to the first data is bigger.

在本发明实施例中，移动终端将按照得到的分配比例划分第一数据的大小，确定通过LTE网络传输的第二数据的大小及通过WiFi网络传输的第三数据的大小。In the embodiment of the present invention, the mobile terminal will divide the size of the first data according to the obtained distribution ratio, and determine the size of the second data transmitted through the LTE network and the size of the third data transmitted through the WiFi network.

在本发明实施例中，通过基于LTE网络的第一传输速率及WiFi网络的第二传输速率划分待传输的第一数据的大小，使得能够充分利用LTE网络和WiFi网络的特性，实现数据的优化分流。In the embodiment of the present invention, by dividing the size of the first data to be transmitted based on the first transmission rate of the LTE network and the second transmission rate of the WiFi network, the characteristics of the LTE network and the WiFi network can be fully utilized to realize data optimization shunt.

For example: the size of the second data is the data of the length 0~(1-R)C of the data corresponding to the resource address, and the size of the third data is the data of the length of (1-R)C~C of the data corresponding to the resource address, so , through the above manner, the sending of the data message request can be effectively realized.
