The present invention relates to the field of communications technologies, and in particular, to a message processing method and apparatus.
With development and popularization of smartphones, various applications on smartphones provide much convenience to people's lives. Because there are more applications installed on the smartphone, there are a growing number of various notification messages such as short message service (SMS) message notifications and push messages of various applications on the smartphone. These notification messages include messages that a user really needs, and also include some spam messages such as advertisement emails and spam SMS messages. It is very inconvenient for the user to read required messages when useful messages and the spam messages are mixed together.
Currently, to manage the notification messages in the smartphone, the user may select to suppress notification messages of some applications, so that the messages of these applications are not displayed in a notification bar. Although a quantity of notification messages can be reduced by using the method, the user easily cannot see important messages in time, and useful messages and spam messages may still exist in applications that are not suppressed. Therefore, the notification message processing method in the prior art is insufficiently intelligent.
Embodiments of the present invention provide a message processing method and apparatus, to resolve a prior-art problem that intelligence of a notification message processing method is relatively low.
To achieve the foregoing objective, the following technical solutions are used in the embodiments of the present invention.
According to a first aspect, an embodiment of the present invention provides a message processing method, including determining an importance level of each application based on a historical use feature of each application on a terminal, and then determining a notification manner of a notification message of each application based on the importance level of each application, so that when receiving a notification message, the terminal displays the notification message in the notification manner corresponding to the application to which the notification message belongs. It can be learned that in this embodiment of the present invention, not all the notification manners are displayed in a same manner, the importance level of each application may be determined based on a use habit of a user for each application, and the notification message of the application of each importance level corresponds to one notification manner, so that notification messages of applications with different importance levels are displayed in different notification manners. Therefore, a requirement and a habit of the user for viewing the message can be satisfied, thereby improving intelligence for processing the notification message.
In a possible design, before displaying the notification message, the terminal further needs to determine a notification time period of each application based on an online time and/or an application type of each application. The online time of the application may reflect a time spent by the user in using the application, and the notification time period of each application is determined with reference to the online time and the application type, so that the notification time period of the application satisfies the use habit of the user. In addition, the application type is considered when the notification time period is determined. For example, a notification time period of a work-type application is a working time, and a notification time period of an entertainment application is a non-working time. Therefore, processing on the notification message is more intelligent.
In a possible design, a specific method for notifying the notification message in the terminal is when receiving a notification message, determining whether a current moment is in the notification time period of the application to which the notification message belongs, and if current moment is in the notification time period of the application to which the notification message belongs, displaying the notification message in the notification manner corresponding to the application to which the notification message belongs, or if current moment is not in the notification time period of the application to which the notification message belongs, temporarily storing the notification message, and displaying, when the current moment reaches the notification time period of the application to which the notification message belongs, the notification message in the notification manner corresponding to the application to which the notification message belongs. The notification message is processed in an appropriate time segment, so that the user is prevented from being interfered by some inopportune notification messages, thereby improving the intelligence for processing the notification message.
In a possible design, the historical use feature includes at least one of use duration, a quantity of times of starting, and a quantity of application download times, and a method for determining the importance level of each application by the terminal is sorting use duration of the applications, and dividing the applications into N first type sets in descending order of the use duration, where N is a positive integer greater than 1, and serial numbers of the N first type sets are 1 to N, sorting quantities of times of starting the applications, and dividing the applications into N second type sets in descending order of the quantities of times of starting, where serial numbers of the N second type sets are 1 to N, sorting quantities of application download times of the applications, and dividing the applications into N third type sets in descending order of the quantities of application download times, where serial numbers of the N third type sets are 1 to N, and then sequentially sifting out an identical application from the first type set, the second type set, and the third type set that correspond to each serial number, to form an importance level set corresponding to each serial number, where a smaller serial number of the importance level set indicates a higher importance level of the application in the importance level set. It can be learned that the importance level of the application is determined based on the use duration of the application, so that it can be ensured that the notification message of the application frequently used by the user is notified in time. Therefore, a notification occasion of the notification message more satisfies the use habit of the user.
In a possible design, in a process in which the terminal sequentially sifts out the identical application from the first type set, the second type set, and the third type set that correspond to each serial number, to form the importance level set corresponding to each serial number, each time an identical application is sifted out from the first type set, the second type set, and the third type set that correspond to one serial number, the identical application in the first type set, the second type set, and the third type set that correspond to the current serial number needs to be used as the importance level set corresponding to the current serial number, and then applications that are not sifted out from the first type set, the second type set, and the third type set that correspond to the current serial number are respectively added to the first type set, the second type set, and the third type set that correspond to a next serial number.
In a possible design, after the terminal determines the importance level of each application based on the use duration, the quantity of times of starting, and the quantity of download times of each application on the terminal, the terminal may further receive a change instruction entered by the user, where the change instruction carries an importance level of the application, and changes, based on the change instruction, the importance level of the application that corresponds to the change instruction to the importance level carried in the change instruction. It can be learned that the terminal may automatically determine the importance level of the application based on historical data, and the user may also change the importance level of the application based on a real-time requirement of the user, so that the notification occasion of the notification message more satisfies the requirement of the user, thereby further improving the intelligence for processing the notification message.
According to another aspect, an embodiment of the present invention provides a message processing apparatus. The apparatus may implement a function performed by the terminal in the foregoing example of the method, and the function may be implemented by using hardware or may be implemented by hardware executing corresponding software. The hardware or software includes one or more modules corresponding to the foregoing function.
In a possible design, a structure of the apparatus includes a processor and a display unit. The processor is configured to enable the apparatus to perform a corresponding function in the foregoing method. The display is configured to enable the apparatus to display the notification message. The apparatus may further include a memory. The memory is configured to couple to the processor and store a necessary program instruction and necessary data of the apparatus.
According to still another aspect, an embodiment of the present invention provides a communications system. The system includes the terminal according to the foregoing aspects and a cloud server.
According to yet another aspect, an embodiment of the present invention provides a computer storage medium, configured to store a computer software instruction used by the foregoing terminal. The computer software instruction includes a program designed for performing the foregoing aspects.
Compared with the prior art, in the embodiments of the present invention, not all the notification manners are displayed in a same manner, the importance level of each application may be determined based on a use habit of a user for each application, and the notification message of the application of each importance level corresponds to one notification manner, so that notification messages of applications with different importance levels are displayed in different notification manners. Therefore, a requirement and a habit of the user for viewing the message can be satisfied, thereby improving intelligence for processing the notification message.

It should be noted that in the embodiments of the present invention, the word “example” or “for example” is used to represent giving an example, an illustration, or a description. Any embodiment or design scheme described as an “example” or “for example” in the embodiments of the present invention should not be explained as being more preferred or having more advantages than another embodiment or design scheme. Exactly, use of the word “example” or “for example” or the like is intended to present a related concept in a specific manner.
It should be noted that in the embodiments of the present invention, “of”, “relevant” and “corresponding” may be mixed during use sometimes. It should be noted that when a difference thereof is de-emphasized, meanings expressed by them are the same.
A terminal, also referred to as user equipment (UE), is a device providing voice and/or data connectivity to a user, for example, a handheld device or an in-vehicle device having a wireless connection function. A common terminal may, for example, include a mobile phone, a tablet computer, a notebook computer, a palmtop computer, a mobile Internet device (MID), a wearable device such as a smartwatch, a smart helmet, a smart band, or a pedometer.
To improve intelligence for processing a notification message, an embodiment of the present invention provides a message processing method. The method is performed by a terminal. As shown in
101. Determine an importance level of each application based on a historical use feature of each application on a terminal.
The historical use feature includes at least one of use duration, a quantity of times of starting, and a quantity of application download times of the application. The use duration of the application is accumulated use duration of the application on a foreground excluding a running time of the application on a background. The quantity of application download times is obtained by the terminal from a cloud server. The cloud server may collect statistics on a total quantity of download times of each application, to determine the quantity of application download times.
It should be noted that the use duration of each application and the quantity of times of starting may reflect a use habit of a user for the application. For example, if the user frequently starts an application, it indicates that the user often needs to use the application, so that the importance level of the application is relatively high. When a notification message of the application is received, the notification message needs to be notified in time, so that the user may see the notification message of the application in time. That is, a longer use duration, a larger quantity of times of starting, and a larger quantity of application download times of an application indicate a higher importance level of the application.
It should be further noted that the terminal periodically collects statistics on the use duration, the quantity of times of starting, and the quantity of application download times of each application, and updates the importance level of the application.
102. Determine a notification manner of a notification message of each application based on the importance level of each application.
For example, there may be three importance levels, and the three importance levels are respectively important, unimportant, and very unimportant.
The notification message of the application whose importance level is important may be prompted by using a pop-up window, and a display location of the notification message of the application whose importance level is important is before that of the notification message of the application whose importance level is unimportant.
If the terminal is in a screen-locked state, the notification message of the application whose importance level is important may be displayed on a lock screen interface by using a pop-up window.
In addition, the notification message of the application whose importance level is important may be set to be prompted at an interval before the user processes the message.
The notification message of the application whose importance level is unimportant may be displayed in a notification bar instead of being prompted by using a pop-up window.
The notification message of the application whose importance level is very unimportant may be a spam SMS message or a spam advertisement, so that the notification message may not be notified.
103. Display, when receiving a notification message, the notification message in the notification manner corresponding to the application to which the notification message belongs.
In an example, it is determined by using step 101 that for a terminal A, an importance level of WeChat is important, an importance level of a microblog is unimportant, and an importance level of QQ is very unimportant.
In this case, when a notification message of WeChat is received, the notification message is displayed by using a pop-up window, as shown in
When a notification message of the microblog is received, the notification message is displayed in a notification bar, and if the notification message of WeChat is not processed at this time, the notification message of the microblog is located below the notification message of WeChat in the notification bar, as shown in
When a notification message of QQ is received, the terminal does not prompt a terminal message of QQ. A user may see the notification message of QQ only when opening the QQ user interface.
It should be noted that if an application has various types of notification messages, a notification policy of each type of the notification message may be preset. For example, an update message of the application may be set to be prompted when the application is started, and a social message of the application is prompted in the notification manner determined in step 102.
Specifically, using WeChat as an example, an update message of WeChat may be set to be prompted by using a pop-up window when WeChat is started, as shown in
In the message notification method provided in this embodiment of the present invention, the terminal may determine the importance level of each application based on the historical use feature of each application, and then determine the notification manner of the notification message of each application based on the importance level of each application, so that when a notification message is received, the notification message is displayed in the notification manner corresponding to the application to which the notification message belongs. Compared with the prior art, not all the notification manners are displayed in a same manner, the importance level of each application may be determined based on the use habit of the user for each application, and the notification message of the application of each importance level corresponds to one notification manner, so that notification messages of applications with different importance levels are displayed in different notification manners. Therefore, a requirement and a habit of the user for viewing the message can be satisfied, thereby improving intelligence for processing the notification message.
A method for determining the importance level of each application based on the use duration, the quantity of times of starting, and the quantity of application download times of each application on the terminal in step 101 is described below.
Use duration of the applications are sorted, the applications are divided into N first type sets in descending order of the use duration, N is a positive integer greater than 1, and serial numbers of the N first type sets are 1 to N. For example, it is assumed that there are nine applications, and the nine applications are an application 1 to an application 9, a first type set 1 is {the application 1, the application 2, and the application 3}, a first type set 2 is {the application 4, the application 5, and the application 6}, and a first type set 3 is {the application 7, the application 8, and the application 9}.
Quantities of times of starting the applications are sorted, the applications are divided into N second type sets in descending order of the quantities of times of starting, and serial numbers of the N second type sets are 1 to N. For example, a second type set 1 is {the application 1, the application 2, and the application 4}, a second type set 2 is {the application 3, the application 5, and the application 6}, and a second type set 3 is {the application 7, the application 8, and the application 9}.
Quantities of application download times of the applications are sorted, the applications are divided into N third type sets in descending order of the quantities of application download times, and serial numbers of the N third type sets are 1 to N. For example, a third type set 1 is {the application 1, the application 3, and the application 5}, a third type set 2 is {the application 2, the application 4, and the application 6}, and a third type set 3 is {the application 7, the application 8, and the application 9}.
In the foregoing processing process, the applications are respectively added into the N first type sets, the N second type sets, and the N third type sets in different manners, and then an identical application is sequentially sifted out from the first type set, the second type set, and the third type set that correspond to each serial number, to form an importance level set corresponding to each serial number. A smaller serial number of the importance level set indicates a higher importance level of the application in the importance level set.
Each time an identical application is sifted out from the first type set, the second type set, and the third type set that correspond to one serial number, the identical application in the first type set, the second type set, and the third type set that correspond to the current serial number is used as the importance level set corresponding to the current serial number, and applications that are not sifted out from the first type set, the second type set, and the third type set that correspond to the current serial number are respectively added to the first type set, the second type set, and the third type set that correspond to a next serial number.
With reference to the foregoing example, an identical application in the first type set {the application 1, the application 2, and the application 3}, the second type set {the application 1, the application 2, and the application 4}, and the third type set {the application 1, the application 3, and the application 5} that correspond to the serial number 1 is the application 1. Therefore, a first importance level set is {the application 1}.
After the first level set is determined, the first type set with the serial number 2 is updated to {the application 2, the application 3, the application 4, the application 5, and the application 6}, the second type set with the serial number 2 is updated to {the application 2, the application 3, the application 4, the application 5, and the application 6}, and the third type set with the serial number 2 is updated to {the application 2, the application 3, the application 4, the application 5, and the application 6}, so that a second importance level set formed by identical applications sifted out from the first type set, the second type set, and the third type set is {the application 2, the application 3, the application 4, the application 5, and the application 6}.
Then, identical applications in the first type set {the application 7, the application 8, and the application 9}, the second type set {the application 7, the application 8, and the application 9}, and the third type set {the application 7, the application 8, and the application 9} that are with the serial number 3 are the application 7, the application 8, and the application 9. Therefore, a third importance level set is {the application 7, the application 8, and the application 9}.
In another example, the applications are sorted based on use duration of the applications, to obtain four first type sets. The four first type sets are respectively a time 1, a time 2, a time 3, and a time 4. The top 20% of the applications whose use duration ranked top form the time 1, the following 30% of the applications form the time 2, the following 30% of the applications form the time 3, and the bottom 20% of the applications form the time 4. The applications are sorted based on the quantities of times of starting, and still based on intervals of 20%, 30%, 30%, and 20% ranked from top to bottom, four second type sets, namely, a count 1, a count 2, a count 3, and a count 4, are sequentially obtained. The applications are sorted based on the quantities of application download times, and still based on the intervals of 20%, 30%, 30%, and 20% ranked from top to bottom, four third type sets, namely, a number 1, a number 2, a number 3, and a number 4, are sequentially obtained. First, an identical application is sifted out from the time 1, the count 1, and the number 1, to form a first importance level set, and then the unselected application in the time 1 is added to the time 2, the unselected application in the count 1 is added to the count 2, and the unselected application in the number 1 is added to the number 2. A second importance level set, a third importance level set, and a fourth importance level set may be sequentially determined based on the method. Importance levels of the applications in the first importance level set, the second importance level set, the third importance level set, and the fourth importance level set decrease sequentially.
Alternatively, identical applications may be sequentially sifted out first from the time 1, the time 2, the time 3, and the time 4 and the count 1, the count 2, the count 3, and the count 4 based on the foregoing method, to obtain four sets, and then the four obtained sets are respectively compared with the number 1, the number 2, the number 3, and the number 4. Finally, the first importance level set, the second importance level set, the third importance level set, and the fourth importance level set are obtained.
Further, after the importance level set is determined, the importance level set is further stored corresponding to the notification manner of the notification message. In this way, after a notification message of the application is received, the notification manner of the notification message may be determined based on the importance level of the application.
For example, a correspondence between the importance level set and the notification manner of the notification message is shown in Table 1:
It should be noted that the correspondence between the importance level set and the notification manner of the notification message in the foregoing table is merely an example, and a quantity of importance levels and the notification manner corresponding to the application in each importance level may be set based on an actual requirement.
Still with reference to the foregoing table, when receiving a message of WeChat, the terminal may determine that WeChat belongs to the first importance level set, and further determine that the notification manner corresponding to the first importance level set is displaying the notification message by using a pop-up window and prompting the notification message through vibration. Therefore, the terminal displays the message of WeChat in a pop-up window and prompts the message through vibration.
When receiving a message of the microblog, the terminal may determine that the microblog belongs to the second importance level set, and further determine that the notification manner corresponding to the second importance level set is displaying the notification message in the notification bar and prompts the notification message through vibration. Therefore, the terminal displays the message of the microblog in the notification bar and prompts the message through vibration.
With reference to the method procedure shown in
201. Determine a notification time period of each application based on an online time and/or an application type of each application.
The terminal may determine the notification time period of each application based on the online time of each application, or determine the notification time period of each application based on the application type of each application, or determine the notification time period of each application based on the online time and the application type of each application.
The terminal may determine the application type of each application by itself, or may obtain the application type of each application from the cloud server.
Specifically, one day 24 hours may be divided into a plurality of time segments. For example, one day is divided into a sleep time segment, a dining time segment, a working time segment, a leisure time segment, and the like. Each application type corresponds to a use time segment. For example, a work-type application is usually used in a working time, and an entertainment type application is usually used in a non-working time.
It is determined based on the online time of each application that the user usually uses each application in which time segment, and it is determined with reference to the application type that the notification time period of each application is the sleep time segment, the dining time segment, or the working time segment. If the online time of the application belongs to two time segments, it is determined that the online time of the application in which time segment is longer, and the time segment in which the online time is longer is determined as the notification time period.
For example, if the online time of the application is from 9:30 to 10:30, it may be determined that the online time of the application is in the working time segment, and the application type of the application is the work-type application, so that it may be finally determined that the notification time period of the application is the working time segment.
It may be understood that based on that the notification time period of each application is determined, when the notification message is received, a moment for displaying the notification message further needs to be determined. Therefore, the displaying, when receiving a notification message, the notification message in the notification manner corresponding to the application to which the notification message belongs in step 103 may be specifically implemented as step 202 to step 204.
202. When receiving a notification message, determine whether a current moment is in the notification time period of the application to which the notification message belongs. If current moment is in the notification time period of the application to which the notification message belongs, perform step 204, or if current moment is not in the notification time period of the application to which the notification message belongs, perform step 205.
For example, if the current moment is the working time segment and the notification time period of the application to which the received notification message belongs is also the working time segment, step 203 may be performed, and the notification is immediately displayed in the notification manner of the application to which the notification message belongs.
If the current moment is the working time segment and the notification time period of the application to which the received notification message belongs is the leisure time segment, step 204 is performed, and the notification is displayed in the notification manner of the application to which the notification message belongs in the leisure time segment.
203. Display the notification message in the notification manner corresponding to the application to which the notification message belongs.
204. Buffer the notification message, and display, when the current moment reaches the notification time period of the application to which the notification message belongs, the notification message in the notification manner corresponding to the application to which the notification message belongs.
In the embodiments of the present invention, not only the notification manner corresponding to the notification message of each application needs to be determined, but also the notification time period of each application needs to be determined, so that the notification message may be notified at an appropriate time. Therefore, the user may see an important notification message in time, and do not miss any common notification message, in addition, a useless notification message is prevented from affecting rest or working of the user, thereby further improving the intelligence for processing the notification message.
It should be noted that the importance level determined by the terminal based on the use duration and the quantity of download times of the application may not always satisfy a subsequent requirement of the user. For example, the user may use an application that is seldom used because of an important working requirement. To make the notification manner of the notification message and the notification time more satisfy the requirement of the user, the user may also manually adjust the importance level of the application. Based on this, in another implementation according to an embodiment of the present invention, as shown in
301. Receive a change instruction entered by a user.
The change instruction of the user may carry an importance level of the application, that is, the user may enter the level of the application in an input box. Alternatively, a setting screen of the terminal may display an importance level option of each application, and the change instruction entered by the user is a click operation on the importance level option of the application.
302. Change, based on the change instruction, the importance level of the application that corresponds to the change instruction to an importance level specified in the change instruction.
It may be understood that the importance level specified in the change instruction is the importance level entered by the user or the importance level selected by the user in step 301.
It should be noted that after changing the importance level of the application based on the change instruction entered by the user, the terminal further needs to perform step 102 again, to determine a notification manner of the notification message of each application again.
In addition, the terminal may further receive a notification time period change instruction entered by the user, and change the notification time period of the application based on the notification time period change instruction, so that the user may set the notification time of the application based on a living habit of the user.
In the message processing method provided in the embodiments of the present invention, the terminal may determine the importance level of each application based on the use duration, the quantity of times of starting, and the quantity of application download times of each application, to determine the notification manner of each application, and determine the notification time period of the notification message of each application based on the online time and the application type of each application. Alternatively, the user may set the importance level of the application and the notification time period. Therefore, the notification manner and the notification time of the notification message more satisfy the requirement of the user, thereby improving the intelligence for processing the message.
