Efficiency, thus ensuring better control of the terminal side. Ensure that the intelligent terminal downloads the PS data at the same time, and does not affect the overall performance of the whole machine due to the current download process, which greatly improves the user experience of the high-end user to the intelligent terminal.

Referring to FIG. 1, which is a main flow of a flow control method according to an embodiment of the present invention, the method can be applied to a terminal in a wireless local area network. Preferably, the terminal in the embodiment of the present invention may refer to an intelligent terminal. The main process of the method is as follows:

Step 101: When the flow control is required, the uplink rate of the terminal is adjusted from the first uplink rate to the second uplink rate, where the first uplink rate is different from the second uplink rate.

The timing of the need for flow control may be determined by the user, for example, when the device is powered on, or may be when data needs to be transmitted, or may be other timings.

When flow control is required, the user can enter the flow control interface of the terminal, In the flow control interface, multiple options can be provided for the user. For example, the options for the uplink rate selectable by the user are 128 kbps, 256 kbps, 384 kbps, 54 Mbps, etc., and the options for the downlink rate selectable by the user are 384 kbps, 512 kbps. , 1Mbps 54Mbps,

108Mbps, etc., the specific rate can be set by the terminal according to the specific situation, or can be set when the terminal is shipped from the factory. For example, a possible traffic setting interface is shown in Figure 2. In Figure 2, the user selects an uplink rate of 128 kbps and a downlink rate of 384 kpbs. After selecting the button, you can click the "OK" button to select it. .

The terminal may have a default uplink rate and a downlink rate, that is, the first uplink rate and the second downlink rate, and the set uplink rate is the first The second uplink rate, the set downlink rate is the second downlink rate.

Step 102: Adjust a downlink rate of the terminal from a first downlink rate to a second downlink rate, where the first downlink rate is different from the second downlink rate.

In the embodiment of the present invention, the user may set the uplink rate and the downlink rate at the same time, or may set only the uplink rate, or may only set the downlink rate, which may be determined by the user.

If the user thinks that the speed of data uploading can be increased, the second uplink rate that is set may be greater than the first uplink rate. If the user thinks that the speed of data uploading can be reduced, the second uplink rate that is set may be Less than the first uplink rate;

If the user thinks that the speed of data downloading can be increased, the second downlink rate that is set may be greater than the first downlink rate. If the user thinks that the speed of data downloading can be reduced, the second downlink rate that is set may be smaller than The first downlink rate.

Step 103: Send a to-be-sent data packet based on the second uplink rate and/or receive a to-be-receive data packet based on the second downlink rate.

After the user sets the uplink rate and the downlink rate and takes effect, the terminal needs to upload according to the set second uplink rate when uploading data, and needs to download data. The download is performed according to the second download rate after the setting.

The receiving, by the frame module, the to-be-received data packet, when the network downlink rate of the WLAN is greater than the second downlink rate, Transmitting the to-be-received data packet to the traffic control module in the terminal, and the traffic control module splits the to-be-received data packet to obtain at least two sub-matches with the second downlink rate. data pack;

And sending, by the flow control module, the at least two sub-data packets to the interface providing module in the terminal; wherein, in the process of sending the sub-data packet, receiving the feedback from the interface providing module Receiving the sub-response information of the previous sub-packet and then transmitting the next sub-packet;

And storing, by the flow control module, at least two sub-response information corresponding to the at least two sub-data packets that are fed back by the interface providing module;

And obtaining, by the flow control module, a first response information based on the two sub-response information;

The first response information is sent to the wireless local area network by the flow control module. That is, the first response information is sent to the framework module by the flow control module, and the first response information is sent by the framework module to the wireless local area network.

In the embodiment of the present invention, the framework module may specifically be a framework layer. For example, if the terminal needs to download data, data can be obtained from the network side by the framework module, and the obtained data is sent to the flow control module. Determining the downlink rate of the network side, for example, the network downlink rate is the fifth downlink rate, and the set downlink rate of the terminal is the second downlink rate, and the second downlink rate is smaller than the fifth Downstream rate. For example, the unit module obtains the first data packet from the network side in a unit time, and sends the first data packet to the flow control module, where the flow control module may use the first data packet. Split, you can split it into at least two sub-packets, each of which is sub-data The capacity of the packet may be smaller than the capacity of the data packet corresponding to the second downlink rate in a unit time.

For example, the fifth downlink rate on the network side is 4 Mbps, and the second downlink rate set for the terminal is 2 Mbps, and the second downlink rate is determined to be smaller than the fifth downlink rate. Receiving the first data packet in a unit time, the capacity of the first data packet is 4M, the first data packet may be split, and the capacity of each sub-packet after splitting needs to be The capacity of the data packet corresponding to the second downlink rate is less than 2M. In this embodiment, the capacity of each sub-packet after the splitting is not greater than 2M.

Preferably, in the splitting, in order to save the steps, the number of splits may be minimized, that is, the number of sub-packets is minimized. In this embodiment, the first data packet may be split into two sub-packets, each Each sub-packet has a capacity of 2M.

Alternatively, the first data packet may be split according to other manners. For example, the first data packet may be split into four sub-data packets, each of which has a capacity of 1 M, or may be The first data packet is split into three sub-packets, wherein the capacity of two sub-packets is 1M, and the capacity of the third sub-packet is 2M. In short, as long as the capacity of each sub-packet after splitting is not more than 2M.

For example, in this embodiment, the first data packet is split into a first sub-data packet and a second sub-data packet, and the capacity of the first sub-data packet and the second sub-data packet are both 2M. After the splitting is completed, the first sub-data packet may be sent to the interface providing module of the terminal, for example, may be an application processor (AP), and receiving the first sub-response information fed back by the interface providing module. Afterwards, the first sub-response information may be first stored, and the second sub-data packet may be sent to the interface providing module. After receiving the second sub-response information fed back by the interface providing module, the second sub-response message may also be stored, and the terminal may use the second sub-response information and the first sub-response The information is combined and can be combined into a first response message, and the first response information can be sent to the network side. Specifically, After the second sub-response information and the first sub-response information are combined into the first response information, the flow control module in the terminal may send the first response information to the frame module. The first response information is sent by the framework module to the network side.

That is, for the network side, the time for receiving the feedback is delayed, and the formula of the rate is the path/time length, and the duration is extended when the distance is unchanged, which is equivalent to lowering the downlink rate.

In the embodiment of the present invention, the step of sending a data packet to be sent based on the second uplink rate may include:

Obtaining, by the flow control module in the terminal, a second data packet to be sent.

And determining, by the flow control module, whether the capacity of the second data packet is greater than a capacity of the data packet corresponding to the second uplink rate in a unit time. The flow control module may send the second data packet to the interface providing module in the terminal, and determine, by the feedback of the interface providing module, whether the capacity of the second data packet is greater than the second uplink The capacity of the packet corresponding to the rate in unit time.

When the determination result is yes, the second data packet is split by the flow control module into at least two sub-packets corresponding to the second uplink rate.

The split sub-packets are sequentially sent to the network side by the flow control module. That is, the flow control module sequentially transmits the split sub-packets to the frame module, and the frame module sequentially transmits the split sub-packets to the network side.

For example, if the terminal needs to upload data, it can first obtain the data to be uploaded. The uplink rate set for the terminal is first determined, for example, the uplink rate set for the terminal is the second uplink rate. For example, the second data packet is obtained by the flow control module in a unit time, and the capacity of the second data packet may be determined to be greater than the capacity of the data packet corresponding to the second uplink rate in a unit time. If it is determined that the capacity of the second data packet is greater than the capacity of the data packet corresponding to the second uplink rate in a unit time, the second number may be According to the packet splitting, it can be split into at least two sub-packets, wherein the capacity of each sub-packet can be smaller than the capacity of the data packet corresponding to the second uplink rate in a unit time. For example, the second uplink rate set for the terminal is 2 Mbps. Obtaining a second data packet, where the capacity of the second data packet is 4M, the second data packet may be split, and the capacity of each sub-packet after splitting needs to be smaller than the second uplink. The capacity of the corresponding data packet in the unit time is required. In this embodiment, the capacity of each sub-packet after the splitting is required to be no more than 2M.

Preferably, in the splitting, in order to save the steps, the number of splits may be minimized, that is, the number of sub-packets is minimized. In this embodiment, the second data packet may be split into two sub-packets, each Each sub-packet has a capacity of 2M.

Alternatively, the second data packet may be split according to other manners. For example, the second data packet may be split into four sub-data packets, each of which has a capacity of 1 M, or may be The second data packet is split into three sub-packets, wherein the capacity of two sub-packets is 1M, and the capacity of the third sub-packet is 2M. In short, as long as the capacity of each sub-packet after splitting is not more than 2M.

For example, in this embodiment, the second data packet is split into a first sub-packet and a second sub-packet, and the capacity of the first sub-packet and the second sub-packet are both 2M. After the splitting is completed, the first sub-data packet may be sent to the frame module, and sent by the frame module to the network side, after receiving the third sub-response information fed back by the network side, And sending the second sub-packet to the framework module, and sending, by the framework module, to the network side. That is, the split sub-packets can be sequentially sent to the network side.

Referring to FIG. 3, an embodiment of the present invention further provides a flow control method, where the method can be applied to a terminal in a wireless local area network. Preferably, the terminal in the embodiment of the present invention may refer to an intelligent terminal. The main process of the method is as follows:

Step 301: Obtain a CPU usage of the terminal. The central processor (CPU) occupancy rate of the terminal may be first obtained to determine whether the CPU usage of the terminal is too large, thereby determining whether flow control is to be performed.

Step 302: When the CPU usage of the terminal is not less than a preset CPU usage threshold, determine whether a data transmission service is occupying the CPU of the terminal.

In the embodiment of the present invention, a CPU usage threshold may be preset, and the CPU usage threshold may be preset according to the specific situation of the terminal, to ensure that the terminal can work normally. If the CPU usage of the terminal is too large, the CPU resources of the terminal may be greatly consumed. Without control, it may seriously affect the normal operation of other data services and even regular services.

If the current CPU usage of the terminal is not less than the CPU usage threshold, it may continue to determine whether a data transmission service is occupying the CPU of the terminal in the terminal.

The method for determining whether the data transmission service occupies the CPU of the terminal in the terminal may be: determining the CPU usage of the data transmission service, if the CPU usage of the data transmission service is greater than 0, indicating that there is a data transmission service in the terminal.

Step 303: When the judgment result is yes, adjust the transmission rate of the data transmission service.

If it is determined that there is a data transmission service in the terminal, the uplink rate and/or the downlink rate of the data transmission service may be adjusted.

Preferably, in the embodiment of the present invention, the uplink rate in the terminal may be preferentially adjusted, because the uploaded data is more CPU-intensive than the downloaded data.

For example, if the terminal has both a service for uploading data and a service for downloading data, the uplink rate may be adjusted first. For example, if the current uplink rate of the terminal is the third uplink rate, it may be adjusted to the fourth uplink rate, where the third uplink rate is greater than the fourth uplink rate. After the third uplink rate is adjusted to the fourth uplink rate, the current CPU usage of the terminal may be obtained again, if the current CPU usage of the terminal is used. If the rate is less than the CPU usage threshold, the uplink rate or the downlink rate is not required to be adjusted. If the current CPU usage of the terminal is still not less than the CPU usage threshold, the uplink rate or downlink rate can be continuously adjusted.

In the embodiment of the present invention, if the CPU usage of the terminal is not less than the CPU usage threshold, the uplink rate may be adjusted until the uplink rate is adjusted to 0, if the CPU usage of the terminal is still not If the CPU usage of the terminal is not less than the CPU usage threshold, the downlink rate may be adjusted until the downlink rate is adjusted to 0. If the CPU usage of the terminal is not less than the CPU usage threshold, the uplink rate may be adjusted. Alternatively, if the CPU usage of the terminal is not less than the CPU usage threshold, the uplink may be adjusted arbitrarily. The rate or the downlink rate, for example, after adjusting the uplink rate, adjusting the downlink rate next time, or for example, adjusting the uplink rate and adjusting the downlink rate in one adjustment. In short, the adjustment method can be varied, and the specific adjustment can be arbitrarily selected, or can be set at the factory.
