It should be understood that the specific embodiments described herein are only used to explain the present application, but not to limit the present application.

FIG. 1 is a schematic diagram of an application environment of a traffic statistics method in an embodiment. As shown in FIG. 1 , the application environment includes a terminal 110 . An application program for querying traffic is installed on the terminal 110, and the user can obtain the total usage amount of the current traffic through the application program. After receiving the traffic statistics request initiated by the application, the terminal 110 obtains the first traffic statistics information recorded in the file system and the second traffic statistics information recorded in the cache, and sums the first traffic statistics information and the second traffic statistics information according to the first traffic statistics information and the second traffic statistics information. Get the current total traffic statistics. It can directly read the file system and obtain the traffic statistics in the cache, and get the current total traffic statistics. It does not need to receive traffic statistics requests every time, and write the traffic statistics in the cache to the file system for statistics, reducing the system resource consumption.

As shown in FIG. 2, in one embodiment, a traffic statistics method is provided. This embodiment is illustrated by taking that the traffic statistics method is mainly applied to the terminal in FIG. 1 as an example. Referring to FIG. 2 , the traffic statistics method includes steps 202 to 206 .

Step 202, receiving a traffic statistics request.

Among them, an application program is installed on the terminal, and traffic statistics can be inquired through the application program. The terminal receives a traffic statistics request triggered by the user to the application. The terminal can detect that the user triggers the query button on the application program through buttons, touch screen, etc., and sends out a traffic statistics request; or the terminal detects the user's gesture operation, recognizes the gesture operation as a traffic statistics command, and sends out a traffic statistics request; or midpoint reception To the voice signal, identify the voice signal as a traffic statistics command, and issue a traffic statistics request.

Step 204: Acquire the first traffic statistics information recorded in the file system in the terminal according to the traffic statistics request, and acquire the second traffic statistics information recorded in the cache in the terminal, where the first traffic statistics information indicates writing The traffic statistics information of the data entered into the file system, the second traffic statistics information represents the traffic statistics information of the data stored in the cache and not written into the file system.

The file system refers to a storage space in the kernel of the terminal for long-term storage of traffic statistics. Write traffic statistics are recorded in the file system. Cache refers to the storage space used to temporarily store traffic statistics. Traffic statistics for a preset duration are stored in the cache. Traffic statistics recorded in the cache are written to the file system at predetermined intervals. For example, the traffic statistics recorded in the cache can be written to the file system every half hour, that is, the traffic statistics collected within half an hour are recorded in the cache. For example, after the traffic statistics recorded in the cache are written to the file system at 10:10, the traffic statistics collected from 10:10 to 10:40 will be stored in the cache first, and at 10:40, the Writes the traffic statistics recorded in the cache to the file system. It can be understood that the predetermined time interval can be set as required, such as 10 minutes, 20 minutes, and the like.

The first traffic statistics information represents the total traffic statistics information written into the file system. For example, the traffic statistics information written to the file system at 10:10, the first traffic statistics information represents the total traffic statistics written into the file system as of 10:10.

The second traffic statistics information represents the traffic statistics information of the data stored in the cache and not written into the file system. The second traffic statistics information may also represent the traffic statistics information recorded in the cache between the first moment and the current moment.
