Up to this point, mobile terminals have been described in terms of their functionality. Hereinafter, a slide-type mobile terminal among various types of mobile terminals, such as a folder-type, bar-type, swing-type, slide-type mobile terminal, and the like, will be described as an example for the sake of brevity. Accordingly, the present invention can be applied to any type of mobile terminal, and is not limited to a slide type mobile terminal.

The mobile terminal 100 as shown in fig. 1 may be configured to operate with communication systems such as wired and wireless communication systems and satellite-based communication systems that transmit data via frames or packets.

A communication system in which a mobile terminal according to the present invention is operable will now be described with reference to fig. 2.

Such communication systems may use different air interfaces and/or physical layers. For example, the air interface used by the communication system includes, for example, Frequency Division Multiple Access (FDMA), Time Division Multiple Access (TDMA), Code Division Multiple Access (CDMA), and Universal Mobile Telecommunications System (UMTS) (in particular, Long Term Evolution (LTE)), global system for mobile communications (GSM), and the like. By way of non-limiting example, the following description relates to a CDMA communication system, but such teachings are equally applicable to other types of systems.

Referring to fig. 2, the CDMA wireless communication system may include a plurality of mobile terminals 100, a plurality of Base Stations (BSs) 270, Base Station Controllers (BSCs) 275, and a Mobile Switching Center (MSC) 280. The MSC280 is configured to interface with a Public Switched Telephone Network (PSTN) 290. The MSC280 is also configured to interface with a BSC275, which may be coupled to the base station 270 via a backhaul. The backhaul may be constructed according to any of several known interfaces including, for example, E1/T1, ATM, IP, PPP, frame Relay, HDSL, ADSL, or xDSL. It will be understood that a system as shown in fig. 2 may include multiple BSCs 275.

Each BS270 may serve one or more sectors (or regions), each sector covered by a multi-directional antenna or an antenna pointing in a particular direction being radially distant from the BS 270. Alternatively, each partition may be covered by two or more antennas for diversity reception. Each BS270 may be configured to support multiple frequency allocations, with each frequency allocation having a particular frequency spectrum (e.g., 1.25MHz,5MHz, etc.).

The intersection of partitions with frequency allocations may be referred to as a CDMA channel. The BS270 may also be referred to as a Base Transceiver Subsystem (BTS) or other equivalent terminology. In such a case, the term "base station" may be used to generically refer to a single BSC275 and at least one BS 270. The base stations may also be referred to as "cells". Alternatively, each sector of a particular BS270 may be referred to as a plurality of cell sites.

As shown in fig. 2, a Broadcast Transmitter (BT)295 transmits a broadcast signal to the mobile terminal 100 operating within the system. In fig. 2, several Global Positioning System (GPS) satellites 300 are shown. The satellite 300 assists in locating at least one of the plurality of mobile terminals 100.

In fig. 2, a plurality of satellites 300 are depicted, but it is understood that useful positioning information may be obtained with any number of satellites. The GPS module 115 as shown in fig. 1 is generally configured to cooperate with satellites 300 to obtain desired positioning information. Other techniques that can track the location of the mobile terminal may be used instead of or in addition to GPS tracking techniques. In addition, at least one GPS satellite 300 may selectively or additionally process satellite DMB transmission.

As a typical operation of the wireless communication system, the BS270 receives reverse link signals from various mobile terminals 100. The mobile terminal 100 is generally engaged in conversations, messaging, and other types of communications. Each reverse link signal received by a particular base station 270 is processed within the particular BS 270. The obtained data is forwarded to the associated BSC 275. The BSC provides call resource allocation and mobility management functions including coordination of soft handoff procedures between BSs 270. The BSCs 275 also route the received data to the MSC280, which provides additional routing services for interfacing with the PSTN 290. Similarly, the PSTN290 interfaces with the MSC280, the MSC interfaces with the BSCs 275, and the BSCs 275 accordingly control the BS270 to transmit forward link signals to the mobile terminal 100.

Based on the above mobile terminal hardware structure and communication system, the present invention provides various embodiments of the method.

As shown in fig. 3, based on the above-mentioned mobile terminal hardware structure and communication system, an embodiment of the terminal file management apparatus of the present invention is proposed, and specifically, the terminal file management apparatus provided by the present invention includes:

the calculating module 31 is configured to calculate a garbage attribute value of the file according to the unused time and the data size of the file, where the garbage attribute value is used to represent a probability that the file belongs to a garbage file;

and the marking module 32 is configured to mark the file with the spam attribute value greater than the preset spam threshold as a spam file.

In practical applications, the files refer to all files in the terminal, and may also refer to only the target file and the file to be marked related to the present invention, and specific contents of these 3 types of files will be described in detail below.

In practical applications, the use of a file includes operations of being viewed, played, copied, moved, read, write, and edited, and the corresponding file is not used includes operations of not being viewed, played, copied, moved, read, write, and edited.

In practical applications, the unused time of the file includes the time length from the last use of the file after downloading to the current time, for example, 11:11 of the last use time of 2016/6/1 and 23:11 of the current time of 2016/6/15, so that the unused time of the file 1 is 14 days and 12 hours, which can be converted into 11.5 days.

In practical applications, the data size of a file may refer to the size of the file itself, for example, if the size of a video file a downloaded by a user is 500M, the data size of the file a is 500M; correspondingly, a plurality of files related to each other may be taken as a whole, for example, a PPT (PowerPoint, presentation) file and music, video, documents and the like introduced by the PPT file are taken as a whole, the size of the whole is calculated, and the whole is taken as the data size of the PPT file, for example, if a user makes a PPT, the size of the PPT file is 1M, 100 music files are cited as background/commentary and the like, the total size of the music files is 500M, 100 documents such as references and the like are also cited as certification files of the PPT, the total size of the documents is 200M, and 3 video files are cited for rest adjustment and use, the total size of the 3 video files is 200M, because the files are related to each other, separate calculation obviously does not conform to the application scenario, the invention calculates the whole, thus, the data size of the PPT file is 901M.

As can be seen from the above description, for some files, such as a viewed video file, a used PPT file, etc., the end user will not use the file for a long time and occupy a large storage space, and these files are files that can be deleted, and the occupied storage space of the terminal can be reduced after deletion.

In order to reasonably determine which files are spam files, the present invention provides an algorithm for spam attribute values of files. Specifically, the calculation module 31 assigns a value to a file in the terminal through an algorithm, where the value is a garbage attribute value and is used to represent the probability that the file belongs to the garbage file, and when the garbage attribute value of a certain file exceeds a preset garbage threshold, such as a certain fixed value, which is commonly used as 1, the garbage attribute value is defined as a garbage file, and waits for cleaning, where the specific algorithm is:

y＝x/a+m/b；

wherein y is a garbage attribute value; x is a variable and can be a decimal corresponding to the unused time of the file; m is the data size of the file and the unit is M; and a and b are constants which can be directly configured by a user, can also be life experience values, and can also be corrected by calculating junk files of all files after the terminal is set by the user for the user to judge whether the calculation is correct.

The mode that a and b are directly configured by a user is simple, and the user can set the mode directly through a man-machine exchange interface and components, such as a display screen, and the detailed description is omitted.

In the method of configuring a and b with a life experience value for a terminal, a habit can be formed by repeating 21 days of actions according to life experiences, so that if one file is not used for 21 days, the file can be recognized as a junk file, and a file larger than 10M is a large file such as an APK, a compressed packet, a video and the like, and the file is not used for many times by users, so that the file is set as a junk file when the value of a is 21 and the value of b is 10, and the file is regarded as a junk file when the value of y is larger than or equal to 1.

For the method of correcting a and b by the terminal, the terminal may perform primary configuration, for example, let a be 10 and b be 5, and calculate the junk files in all files, so that a lot of junk files are obtained by calculation, which may include some video files that are just downloaded by the user, and the user determines that the calculation is wrong, and perform secondary configuration, for example, let a be 15 and b be 8, and recalculate the junk files in all files, and sequentially loop until reasonable values of a and b are obtained.

When the calculated junk attribute value of a certain file is larger than a preset junk threshold value, marking the file as a junk file; specifically, the marking module 32 may mark the files as garbage files by adding fields, setting garbage file identifiers, and the like.

In practical applications, the calculation module 31 and its calculation function, the marking module 32 and its marking function may be implemented by the controller 150, and at this time, the controller 150 may obtain the unused time and the data size of each file in the terminal, and then according to an algorithm formula: and when the garbage attribute value of a certain file is greater than 1, marking the file as a garbage file.

As shown in fig. 3, the terminal file management apparatus further includes a screening module 33, where the screening module 33 is configured to screen all files in the terminal according to the white list, determine a target file that does not belong to the white list, transmit the target file to the calculation module to calculate a spam attribute value of the target file, and also may be configured to set a time length threshold for calculating the spam attribute value, screen the target file according to the time length threshold, mark the target file whose unused time length is greater than the time length threshold as a file to be marked, and periodically calculate the spam attribute value of the file to be marked.

The screening module provided by the embodiment of the invention is used for avoiding mistakenly marking some files, such as favorite files of a user or system files/encrypted files, as junk files, and also can avoid directly marking some large files which are just downloaded as junk files.

In practical application, even if some files in the terminal are not used for a long time, a user does not want to delete the files, such as some pictures, music and the like, and in order to avoid marking the files as junk files, the invention provides a white list mechanism. That is, in practical applications, the manner of setting the white list includes: adding the system file and the encrypted file to a management white list; and/or adding the preference file selected by the user to the management white list.

Specifically, as shown in fig. 7, in the configuration interface diagram, the terminal directly adds the system file and the encrypted file into the white list, so as to avoid system crash caused by mistaken deletion of the user.

Specifically, as shown in fig. 8, in the configuration interface diagram, a user may select all files under a certain application to directly add to a white list, or may only add some favorite files to the white list, so as to avoid marking the favorite files of the user as junk files.

In practical application, for some large video files just downloaded by a user, if the algorithm is directly adopted for calculation, the large video files are directly regarded as junk files, and user experience is affected, for this reason, the parameter of the time length threshold is provided, for example, 10 days, the parameter is assumed that when a certain file is not used for more than 10 days in a mobile phone terminal power-on state, the algorithm is started to calculate the junk attribute value, for example, when the file size is about 100K, the parameter is substituted into the formula to calculate that the file needs 21 days, similarly, when the file size is 1M, the number of days is calculated to be 19 days, when the file size is more than or equal to 10M, the number of days is calculated to be 10 days (here, ten days are 10 days of waiting), and 10 days are enough for the user to watch the corresponding video, and if the files are liked, the files can be added into a white list.

In practical applications, if a user reuses a file already marked as a junk file at a certain time, it is necessary to restore the file to an original state (a state in which the file is not marked with the junk file), and recalculate the junk attribute value.

The function and the implementation principle of the screening module 33 are briefly described above, in practical application, the screening module 33 and the marking function thereof may be implemented by the controller 150, at this time, the controller 150 may display a white list setting interface and a time length threshold through the display module 131, receive user setting operation, complete setting of the white list and the time length threshold, then screen all files in the terminal according to the white list and the time length threshold, all files refer to any file (including files 1 to 20) of the terminal, then screen out target files according to the white list, that is, screen out user preference files (file 1) and system files/encrypted files (files 2 and 3) in all files, the remaining files are target files (including files 4 to 20), count unused time for the target files, when the unused time of some files (files 5-9) is larger than the time length threshold value, the files are taken as files to be marked (including files 5-9), and the garbage attribute values of the files to be marked (files 5-9) are respectively calculated.

As shown in fig. 3, the terminal file management apparatus further includes a deleting module 34 configured to delete a file marked as a junk file when a deleting condition is satisfied.

The terminal file management device may further include a display module 35, configured to display the file marked as the junk file, and notify the deletion module of the cleaning object in the file marked as the junk file according to the received selection operation instruction, where the deletion module is configured to delete the junk file corresponding to the cleaning object.

In practical application, the terminal can set various deleting conditions according to user operation, and if the storage space of the terminal is lower than 15%, a process of deleting the junk files is started; or, periodically starting a process of deleting the junk files; or, when the terminal storage space can not store the files required to be downloaded by the user, starting a process of deleting the junk files; or, when receiving a command that the user needs to delete the junk file, starting a process of deleting the junk file, and the like. The terminal can set and activate a deletion condition, and can also set and activate all deletion conditions so as to ensure that the storage space of the terminal is cleaned to the maximum extent.

When the terminal meets the deletion condition, a process of deleting the junk files is started, wherein the deletion process can directly delete all files marked as the junk files, can delete a preset number of files marked as the junk files with the junk attribute values ranked in the front, and can display the junk files to a user for the user to select.

In practical application, the scheme of directly deleting all the files marked as garbage files can be realized simply and is not described any further.

In practical application, deleting a predetermined number of files marked as junk files with junk attribute values ranked first requires calculating and updating the junk attribute values of the junk files all the time, and performing sequencing updating.

In practical application, deleting a predetermined number of files marked as junk files before the time of marking as junk files, the time of marking as junk files of each file is required to be recorded, and the files are sorted, and the earlier marked as junk files, the more likely the file is not used any more by a user, the more likely the file is deleted, and the conventional use requirements of the user are met.

In practical application, the way of displaying the junk files to the user for the user to select is most in accordance with the use requirements of the user, so that the favorite files of the user can be prevented from being deleted, meanwhile, the terminal files are too many, and the user is difficult to add all the favorite files to a white list, the junk files corresponding to the deletion do not need to be selected from all the files of the terminal one by one, and only simple selection needs to be performed on a deletion interface.

As shown in fig. 9, the deletion interface displays all junk files in a list manner, and the user may select the junk files.

As shown in fig. 10, the deletion interface displays all junk files in a list manner, and also displays parameters such as acquisition date/source of the corresponding file, so that the user can refer to the parameters when selecting the junk files, and determine whether the junk files are junk files without opening the files.

In practical application, the deleting module 34 and the deleting function thereof may be implemented by the controller 150, and the displaying module 35 and the displaying function thereof may be implemented by the display module 131, at this time, the controller 150 may detect whether a deleting condition is satisfied, if so, the display module 131 displays a garbage file list for a user to select a file to be deleted, receives a user setting operation, completes selection of a deleted object, and then deletes the file.

According to the terminal file management device provided by the embodiment, the garbage attribute value of the file is calculated according to the unused time and the data size of the file by acquiring the parameters of the unused time, the data size and the like of the file, the garbage attribute value is used for representing the probability that the file belongs to the garbage file, and when the garbage attribute value of the file is larger than a garbage threshold value, the corresponding file is marked as the garbage file; therefore, whether the files in the terminal are junk files or not can be managed, the files meeting the conditions are marked as the junk files, and the junk files can be displayed for a user to select to delete when the deletion conditions are met.

As shown in fig. 5, a first embodiment of the terminal file management method of the present invention is provided, in which the terminal file management method includes the following steps:

s501: and calculating the junk attribute value of the file according to the unused time and the data size of the file, wherein the junk attribute value is used for representing the probability that the file belongs to the junk file.

In practical applications, the files refer to all files in the terminal, and may also refer to only the target file and the file to be marked related to the present invention, and specific contents of these 3 types of files will be described in detail below. The use of a file includes operations of being viewed, played, copied, moved, read, written, edited, etc., and the non-use of the corresponding file includes operations of not being viewed, played, copied, moved, read, written, edited, etc. The unused time of the file includes the time length from the last use of the file after downloading to the current time, for example, 11:11 when the last use of the file 1 is 2016/6/1 and 23:11 when the current time is 2016/6/15, then the unused time of the file 1 is 14 days and 12 hours, and it is anticipated that this can be converted to 11.5 days. The data size of the file may refer to the size of the file itself, for example, if the size of the video file a downloaded by the user is 500M, the data size of the file a is 500M; correspondingly, a plurality of files related to each other may be taken as a whole, for example, a PPT (PowerPoint, presentation) file and music, video, documents and the like introduced by the PPT file are taken as a whole, the size of the whole is calculated, and the whole is taken as the data size of the PPT file, for example, if a user makes a PPT, the size of the PPT file is 1M, 100 music files are cited as background/commentary and the like, the total size of the music files is 500M, 100 documents such as references and the like are also cited as certification files of the PPT, the total size of the documents is 200M, and 3 video files are cited for rest adjustment and use, the total size of the 3 video files is 200M, because the files are related to each other, separate calculation obviously does not conform to the application scenario, the invention calculates the whole, thus, the data size of the PPT file is 901M.

In order to reasonably determine which files are spam files, the present invention provides an algorithm for spam attribute values of files. Specifically, the calculation module 31 assigns a value to a file in the terminal through an algorithm, where the value is a garbage attribute value and is used to represent a probability that the file belongs to a garbage file, and when the garbage attribute value of a certain file exceeds a garbage threshold, such as a certain fixed value, which is commonly used as 1, the garbage file is defined as a garbage file, and waits for cleaning, where the specific algorithm is: y is x/a + m/b; wherein y is a garbage attribute value; x is a variable and can be a decimal corresponding to the unused time of the file; m is the size of the file and the unit is M; and a and b are constants which can be directly configured by a user, can also be life experience values, and can also be corrected by calculating junk files of all files after the terminal is set by the user for the user to judge whether the calculation is correct.

In order to avoid some special files, such as user favorite files, system files, etc. from being incorrectly marked as garbage files, before calculating the garbage attribute value of the file, the method further comprises:

setting a white list;

acquiring unused time and data size of a target file;

calculating the garbage attribute value of the file comprises: and calculating the junk attribute value of the target file.

screening target files according to the time length threshold value, and recording the target files with the unused time length larger than the time length threshold value as files to be marked;

calculating the garbage attribute value of the target file comprises the following steps: the garbage attribute value of the file to be marked is periodically calculated.

In practical application, even if some files in the terminal are not used for a long time, a user does not want to delete the files, such as some pictures, music and the like, and in order to avoid marking the files as junk files, the invention provides a white list mechanism, and at the moment, the user can set a white list to be added to prevent mistaken deletion, and system files and encrypted files cannot be deleted, and the system files and the encrypted files which cannot be deleted in the terminal are automatically added into the white list. That is, in practical applications, the manner of setting the white list includes: adding the system file and the encrypted file to a management white list; and/or adding the preference file selected by the user to the management white list.

S502: and marking the file with the junk attribute value larger than a preset junk threshold value as a junk file.

When the calculated junk attribute value of a certain file is larger than a preset junk threshold value, marking the file as a junk file; specifically, the files can be marked as junk files by adding fields, setting junk file identifiers and the like.

In order to clean up terminal storage space rationally, still include:

setting a deleting condition for deleting the junk files;

In order to avoid deleting the user preference file, before deleting the file marked as a junk file, the method further comprises the following steps:

displaying the files marked as junk files;

deleting files marked as junk files includes: and deleting the junk files corresponding to the cleaning objects.

The method for managing the terminal file provided by the embodiment includes the steps that parameters such as unused time and data size of the file are obtained, a junk attribute value of the file is calculated according to the unused time and the data size of the file, the junk attribute value is used for representing the probability that the file belongs to the junk file, and when the junk attribute value of the file is larger than a junk threshold value, the corresponding file is marked as the junk file; therefore, whether the files in the terminal are junk files or not can be managed, the files meeting the conditions are marked as the junk files, and the junk files can be displayed for a user to select to delete when the deletion conditions are met.
