Detailed ways

In order to make the technical problems solved by the present invention, the technical solutions adopted and the technical effects achieved clearer, the technical solutions of the embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings. Obviously, the described embodiments are only the technical solutions of the present invention. Some, but not all, embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative efforts fall within the protection scope of the present invention.

Please refer to FIG. 1 , which is a method flow chart of an embodiment of a method for increasing the data transmission speed of a mobile device provided in the specific embodiments of the present invention. As shown in the figure, the method includes:

Step a: When the mobile device detects MTP-based data transmission with the external storage, adjust the CPU of the mobile device to output the maximum performance.

Step b: Set a duration t, which is the duration of the maximum performance output.

MTP is an extension based on the PTP (Picture Transfer Protocol) protocol. It is mainly used to transfer media files. MTP can be implemented on both the USB protocol and the TCP/IP protocol. It belongs to the upper layer application protocol and does not care about the bottom layer. Transfer Protocol. At present, the applications of most devices are based on the USB protocol. However, due to the design of the MTP protocol itself, it is impossible to judge when the MTP data transmission ends during the data transmission process. During the transmission process, the CPU only performs data processing during the data transmission process according to the data processing capacity in the normal working state. However, the data processing capability of the CPU under normal working conditions is far lower than its designed maximum data processing capability, and the CPU generally does not operate at full capacity with the maximum data processing capability as its normal working state.

In this solution, in order to increase the speed of data transmission, the idle computing power of the CPU is utilized. When the mobile device detects data transmission based on MTP, it adjusts the working state of the CPU so that it can achieve the maximum performance output and improve the efficiency of data processing. speed, thereby improving the user experience.

To sum up, by adjusting the CPU of the mobile device to the maximum performance output when the mobile device detects the MTP-based data transmission with the external storage body, the progress of the data transmission is periodically detected during the maximum performance transmission process, if the data When the transmission is over, the maximum performance output will be terminated, otherwise the maximum performance output will continue; the operating state of the CPU is adjusted according to the needs of data transmission, which improves the data transmission speed and enhances the user experience.

Preferably, the maximum performance output is specifically that the operating frequency of the CPU is adjusted to the highest designed frequency.

The CPU frequency is the clock frequency of the CPU. Simply put, it is the abbreviation of the working frequency of the CPU during operation (the number of synchronous pulses that occur within 1 second). The unit is Hz. It determines the running speed of the computer. With the development of the computer, the main frequency has been developed from the past MHZ to the current GHZ (1GHZ=10^3MHZ=10^6KHZ=10^9HZ). Because the increase of CPU energy consumption speed is directly proportional to the increase of CPU operating frequency, the higher the operating frequency, the speed of energy consumption can be said to increase geometrically, so in the actual operation process, the CPU generally maintains a For a relatively moderate frequency, after the operating frequency is increased, the speed of data processing will not increase significantly, but the loss caused by heat generation and loss will increase significantly. In this solution, in the special working state of MTP data transmission, the operating frequency of the CPU is increased and directly set to the highest design frequency to increase the data transmission speed; of course, you can also choose to adjust to a state that is closer to the design highest frequency. .

Further, the CPU is a multi-core CPU, and the maximum performance output specifically includes enabling all cores of the CPU.

With the continuous development of electronic technology, the core of the CPU has evolved from single-core to dual-core, quad-core or even eight-core. The more cores can bring faster data processing speed, but generally there will be a certain amount of idle performance. In the process of MTP data transmission, this part of idle performance is activated to further increase the data processing speed, thereby shortening the time required for MTP data transmission.

Further, the designed maximum frequency is adjusted through a frequency modulation interface provided by the system of the mobile device.

For a general mobile device, its system is provided with an interface for adjusting the CPU. In this solution, the interface is accessed to adjust the operating frequency of the CPU during frequency adjustment.

Preferably, the duration t is 1-3 minutes.

The MTP protocol is generally used to transmit multimedia files. According to the size of multimedia files and the required transmission time, it is more appropriate to confirm whether the data transmission is completed every 1 to 3 minutes. Maximum performance output, and will not frequently obtain data transmission status.

The following is an embodiment of a device for increasing the data transmission speed of a mobile device in this solution. The embodiment of the device for increasing the data transmission speed of a mobile device is implemented based on the embodiment of the method for increasing the data transmission speed of a mobile device. In the embodiment of the device, there is no For a complete description, please refer to the examples of methods.
