Referring to fig. 2, fig. 2 is a schematic flow chart illustrating an implementation of the cache data cleaning method according to the first embodiment of the present invention. The cache data cleaning method provided in this embodiment can be applied to the terminal 10 shown in fig. 1, as shown in fig. 2, the method mainly includes the following steps:

s101, regularly acquiring the use frequency of applications preset in a terminal and the reading record of cache data of each application within a preset time length;

specifically, the predetermined period and the preset time duration may be set according to a user-defined operation, and optionally, the predetermined period and the preset time duration are both set as default to one day (24 hours), for example, 12 hours per night: 00 obtains the use frequency of each Application (APP) installed in the terminal within 24 hours (0: 00-24: 00) of the day, and the reading record of the cache data of each APP within 24 hours of the day.

The preset APP types in the terminal may include, but are not limited to: web browsing, instant messaging, multimedia playing, and social, among others. In practical application, the APP preset in the terminal may refer to all APPs installed in the terminal, or may refer to a part of APPs specified by a user in all APPs installed in the terminal. And taking the packet name of each APP as an index key, and recording the use times and the use duration of each APP. The use frequency indicates the use times of each APP in a preset time length, such as: 5 times per day.

And reading the generation time of each cache data read within a preset time length in all the cache data of each APP recorded in the record. For example: if the user checks 12 chat records of yesterday and the last day in 24 hours through the instant messaging APP, the generation time of the 12 chat records is recorded in the reading record.

S102, determining the number of cache data retention days corresponding to each application according to the use frequency and the reading record;

and analyzing the habit of the user for browsing the cache data of different APPs according to the generation time of the read cache data of each APP within the preset time length recorded in the read record. And establishing a data cleaning model according to the use frequency of each APP and the habit of a user browsing the cache data of different APPs so as to determine the respective corresponding cache data retention days of the different APPs. It is understood that the higher the usage frequency, the earlier the generation time of the read cache data within the preset time length is, and the longer the number of cache data retention days is.

S103, when the system time reaches a preset cleaning time point, searching data to be cleaned in the cache data of each application according to the number of days for retaining each cache data, and cleaning.

The preset cleaning time point can be set according to user-defined operation of a user. And detecting whether the system time reaches the preset cleaning time point, and searching and cleaning data to be cleaned in the cache data of the APP corresponding to each cache data retention day according to each cache data retention day when the system time reaches the preset cleaning time point. The data to be cleaned is the data with the cache duration exceeding the number of cache data retention days in the cache data of each APP.

It should be noted that, acquiring the use frequency and the read record, and determining the number of cache data retention days corresponding to each application according to the use frequency and the read record is a process of periodically triggering execution for multiple cycles. When the starting time point of the first preset time limit arrives, triggering and executing the steps of acquiring the use frequency and the reading record, and determining the number of cache data retention days corresponding to each application according to the use frequency and the reading record; and when the starting time point of the next preset time limit arrives, triggering and executing the steps of obtaining the use frequency and the reading record again, determining the number of cache data retention days corresponding to each application according to the use frequency and the reading record, and repeating the steps until the number of circulation reaches the preset number or the interruption operation is interrupted according to the interruption operation of the user.

Similarly, at the preset cleaning time point, the process of executing the cache data cleaning operation is also a process of periodically triggering the execution for multiple times of circulation. The cycle of executing the cache data cleaning operation may be consistent with or inconsistent with the cycle of obtaining the use frequency and the read record, and determining the number of cache data retention days corresponding to each application according to the use frequency and the read record. For example, the operation of acquiring the usage frequency and the read record once a day, and determining the number of cache data retention days corresponding to each application according to the usage frequency and the read record may be performed, but the operation of performing the cache data cleaning operation at the preset cleaning time point may be performed once every three days.

According to the cache data cleaning method provided by the embodiment of the invention, the use frequency of the applications preset in the terminal and the reading records of the cache data of each application are regularly obtained within the preset duration, and the data cleaning model is established by combining the use frequency and the generation time of the cache data of each application read within the preset duration recorded in the reading records, and the cache data of each application is specifically processed according to the data cleaning model; on the other hand, the data cleaning model is established based on the use frequency of each application and the habit of browsing the cache data by the user, so that the cleaning operation has more flexibility and pertinence, and the actual requirements of the user are better met, thereby being more intelligent.

Referring to fig. 3, fig. 3 is a schematic flow chart illustrating an implementation of a cache data cleaning method according to a second embodiment of the present invention. The cache data cleaning method provided in this embodiment can be applied to the terminal 10 shown in fig. 1, as shown in fig. 3, the method mainly includes the following steps:

s201, regularly acquiring the use frequency of applications preset in the terminal and the reading record of cache data of each application within a preset time length;

specifically, the predetermined period and the preset time duration may be set according to a user-defined operation, and optionally, the predetermined period and the preset time duration are both set as default to one day (24 hours), for example, 12 hours per night: 00 obtains the use frequency of each Application (APP) installed in the terminal within 24 hours (0: 00-24: 00) of the day, and the reading record of the cache data of each APP within 24 hours of the day.

The preset APP types in the terminal may include, but are not limited to: web browsing, instant messaging, multimedia playing, and social, among others. In practical application, the APP preset in the terminal may refer to all APPs installed in the terminal, or may refer to a part of APPs specified by a user in all APPs installed in the terminal. And taking the packet name of each APP as an index key, and recording the use times and the use duration of each APP. The use frequency indicates the use times of each APP in a preset time length, such as: 5 times per day.

And recording the generation time of each read cache data in all the cache data of each APP within a preset time length in the read record. For example: if the user checks 12 chat records of yesterday and the last day in 24 hours through the instant messaging APP, the generation time of the 12 chat records is recorded in the reading record.

S202, respectively obtaining target data with the earliest generation time from the generation time of each cache data recorded in each reading record, and taking the generation time of each target data as the browsing span of each corresponding application;

browsing span, which indicates how many days ago a user may view cache data of a certain APP, such as: the instant messaging APP user only looks at the current day chat records and the friend circle messages, and the user can often look at yesterday or previous day cache information. In other words, the browsing span can be considered as: and the time span between the acquisition time of the read record and the generation time of the data with the longest cache duration in all the cache data viewed by the user within the preset duration recorded in the read record. It will be appreciated that the earlier the production time, the greater the time span or browsing span. For example: and 9, 5 days in 9 months, wherein the chat records of 3 days in 9 months and 2 days in 9 months are checked by the WeChat user, so that 5 days in 9 months, the time span of WeChat is 3 days, and the browsing span is 2 days in 9 months. Alternatively, the day or hour is used as a measure of the viewing span.

Or, the cache duration of the data with the earliest time generated in all the cache data of the APP viewed by the user within the preset duration recorded in the read record of a certain APP may be used as the browsing span of the APP.

S203, determining the number of cache data retention days corresponding to each application according to the use frequency and the browsing span;

specifically, the determining method for determining the number of cache data retention days corresponding to each APP according to the use frequency and the browsing span may include the following steps:

step one, ranking the frequency of each application according to the sequence of the use frequency from high to low, and determining the frequency integral of each application according to a ranking result and a preset frequency integral determining rule;

TABLE 1

APP Frequency of use (times/day) Browsing span (time) Pkg1 A1=10 B1 day (or 3 days) 9 month Pkg2 A2=30 B2 day 2 month (or 4 days) Pkg3 A3=17 B3 day 1 month (or 5 days) Pkg4 A4=25 B4-8 month-30 days (or 7 days) …… …… ……

TABLE 2

Specifically, with reference to table 1 and table 2, the frequency ranking of the APPs is performed in the order of the use frequency from high to low, and the higher the use frequency, the higher the ranking. And secondly, determining the frequency integral of each APP according to the ranking result of the frequency ranking and a preset frequency integral determining rule, wherein the frequency integral is more when the frequency ranking is higher.

Further, determining the frequency integral of each APP according to the ranking result of the frequency ranking and a preset frequency integral determination rule, specifically comprising: and determining a preset upper limit value of the frequency integral as the frequency integral of the APP with the first frequency ranking, and then determining the frequency integral of other APPs except the APP with the first frequency ranking according to a mode of gradually decreasing the preset decreasing interval of the frequency integral. Or, further, when determining the frequency integrals of the APPs other than the APP with the first frequency rank in a manner of being gradually decreased according to a preset frequency integral decreasing interval, when decreasing to a preset frequency integral lower limit value, determining the frequency integral lower limit value as the frequency integral of all the remaining APPs for which the frequency integral is not determined.

For example, as shown in table 2 above, assuming that the preset upper limit value of the frequency integral is 10 points, the preset lower limit value of the frequency integral is 1 point, the decrement interval of the frequency integral is 1, and the frequency ranking results are as follows in order from top to bottom: pkg2, Pkg4, Pkg3, Pkg1, Pkg7, Pkg5, Pkg6, Pkg8, Pkg9, Pkg10 and Pkg11, the corresponding integrals are respectively as follows according to the frequency integral determination rule: pkg2 ═ 10 points, Pkg4 ═ 9 points, Pkg3 ═ 8 points, Pkg1 ═ 7 points, Pkg7 ═ 6 points, Pkg5 ═ 5 points, Pkg6 ═ 4 points, Pkg8 ═ 3 points, Pkg9 ═ 2 points, Pkg10 ═ 1 points, and Pkg11 ═ 1 points. It can be understood that when the integral reaches the lower limit value when the Pkg10 is determined, the frequency integral of each APP (such as the Pkg11) after the rank 10 is all 1.

Step two, carrying out span ranking on each application according to the sequence of browsing spans from large to small, determining the span integral of each application according to a ranking result and a preset span integral determining rule, wherein the higher the span ranking is, the more the span integral is;

specifically, with reference to the above table 1 and table 2, first, the APP is ranked in order of browsing span from large to small, that is, in order of generation time of the target data, where the earlier the generation time is, the larger the browsing span is. Secondly, determining the span integral of each APP according to the ranking result and a preset span integral determination rule, wherein the higher the span ranking is, the more the span integral is.

Further, determining the span integral of each APP according to the ranking result and a preset span integral determination rule specifically includes: determining a preset span integral upper limit value as the span integral of the APP with the first span ranking; and determining the span integrals of other APPs except the APP with the first span ranking in a mode of gradually decreasing according to a preset span integral decreasing interval. Or, further, when determining the span integrals of other APPs except the APP with the first span ranking in a manner of gradually decreasing according to a preset span integral decreasing interval, when decreasing to a preset span integral lower limit value, determining the span integral lower limit value as the span integral of all the remaining APPs for which the span integral is not determined.

For example, as shown in table 2 above, assuming that the preset upper value of the span integral is 10 minutes, the preset lower value of the span integral is 1 minute, the descending interval of the span integral is 1, and the span ranking results are sequentially from high to low: pkg4, Pkg3, Pkg2, Pkg1, Pkg5, Pkg6, Pkg7, Pkg8, Pkg9, Pkg10 and Pkg11, the corresponding integrals are respectively: pkg4 ═ 10 points, Pkg3 ═ 9 points, Pkg2 ═ 8 points, Pkg1 ═ 7 points, Pkg5 ═ 6 points, Pkg6 ═ 5 points, Pkg7 ═ 4 points, Pkg8 ═ 3 points, Pkg9 ═ 2 points, Pkg10 ═ 1 points, and Pkg11 ═ 1 points. It can be understood that, for the top 10 APPs, the integral is determined in a decreasing manner, and when the 10 th APP is determined, the integral after the 10 th APP is 1 point because the integral reaches the lower limit value.

Step three, obtaining the total integral of each application according to the frequency integral and the frequency weight value corresponding to the frequency integral and the span weight value corresponding to the span integral;

the frequency weight value that the frequency integral corresponds and the span weight value that the span integral corresponds can set up according to user's custom operation, and wherein, frequency weight value + span weight value equals 100%, and each APP's total integral equals frequency integral value + span integral value. Optionally, the frequency weight value is 40% and the span weight value is 60%.

And fourthly, performing score ranking on each application according to the sequence of the total scores from most to few, and determining the cache data retention days corresponding to each application according to the ranking result and a preset determination rule, wherein the higher the score ranking is, the longer the corresponding cache data retention days are.

TABLE 3

Total points ranking Number of cache data retention days Pkg4 5 Pkg2 4 Pkg3 3 Pkg1 2 Pkg5 1 …… 1

Specifically, with reference to tables 1 to 3, the APP is subjected to integral ranking in the order of the total integral from the top to the bottom, and the higher the total integral is, the higher the ranking is. Secondly, determining the number of cache data retention days corresponding to each APP according to the ranking result and a preset determination rule, wherein the higher the integral ranking is, the longer the number of cache data retention days corresponding to each APP is.

Further, determining the number of cache data retention days corresponding to each APP according to the ranking result and a preset determination rule specifically includes: determining a preset upper limit value of cache data retention days as cache data retention days corresponding to the APP with the first integral ranking; and determining the number of cache data retention days corresponding to other APPs except the APP with the first integral ranking according to a mode of gradually decreasing according to a preset total integral decreasing interval. Further, when determining the number of cache data retention days corresponding to other APPs except for the APP with the first integral ranking in a manner of gradually decreasing according to a preset total integral decreasing interval, and when decreasing to a preset lower limit value of the number of cache data retention days, determining the lower limit value as the number of cache data retention days corresponding to the remaining APPs with undetermined retention days. The upper limit value of the number of cache data retention days can be configured according to user-defined operation of a user. Optionally, an average value of the cache durations of the target data corresponding to each APP may be taken as an upper limit value of the number of cache data retention days.

For example, as shown in table 3 above, assuming that the preset upper limit of the number of cache data retention days is 5 days, the lower limit of the number of cache data retention days is 1 day, and the total point decrement interval is 1, the ranking results of the points from Pkg1 to Pkg5 are as follows from high to low: pkg4(9 × 40% +10 × 60% ═ 9.6 points), Pkg2(10 × 40% +8 × 60% + 8.8 points), Pkg3(8 × 40% +9 × 60% + 8.4 points), Pkg1(7 × 40% +7 × 60% +7 points), and Pkg5(5 × 40% + 6% + 60% + 5.6 points), the corresponding days of retention were, according to the above-identified rules: 5 days for Pkg4, 4 days for Pkg3, 3 days for Pkg2, 2 days for Pkg1 and 1 day for Pkg 5. If the total integral of other APPs is less than Pkg5, the remaining days for the other APPs are all 1 day.

And S204, when the system time reaches a preset cleaning time point, searching the data to be cleaned in the cache data of each application according to the number of the reserved days of each cache data, and cleaning.

And detecting whether the system time reaches a preset cleaning time point, and searching and cleaning data to be cleaned in the cache data of each APP according to the number of days of retention of each cache data when the system time reaches the preset cleaning time point. Wherein, the data to be cleaned is: in the cache data of each APP, the cache duration exceeds the data of the cache data retention days. For example, as shown in table 3, the application of Pkg4 will clear the buffered data generated 5 days ago each day, Pkg2 will clear the data generated 4 days ago each day, Pkg3 will clear the data generated 3 days ago each day, and so on.

In another embodiment of the present invention, cache data scrubbing may be selectively performed.

For example, in connection with table 3, it is assumed that the cached data before 3 days of Pkg4 is currently processed according to the target retention days (3 days) of Pkg4 input by the user, and the cache data retention days corresponding to the Pkg4 is 5 days. At this time, the error between the target number of retention days corresponding to Pkg4 and the number of retention days of the cache data is-2, and is out of the preset error interval [ -1, 1 ]. If the error is-2 for 10 times and the preset number of times is 7 for Pkg4 in the process of the data cleaning operation, the number of cache data retention days of Pkg4 is adjusted to 3 days. Meanwhile, the modification authority of the number of cache data retention days of the Pkg4 is locked, so that the number of cache data retention days of the Pkg4 is not modified. The specific locking mode can be by adding a forbidden revision flag, or setting the attribute of the setting parameter of the number of cache data retention days of Pkg4 as unchangeable.

Furthermore, the user can be regularly reminded of carrying out manual cleaning operation, and then the cache data retention days are adjusted according to the manual cleaning habit of the user when the user carries out the manual cleaning operation. Specifically, prompt information is output periodically to prompt a user to clear cache data of each APP; and responding to a cleaning instruction triggered by a user, and cleaning data of which the cache duration exceeds the target retention days in the cache data of the target APP pointed by the cleaning instruction according to the target retention days input by the user.
