Based on the hardware structure of the mobile terminal 100 and the communication network system, various embodiments of the method of the present invention are provided.

First, the present invention provides a lock screen display method, which is applied to a mobile terminal shown in fig. 1 to 2, where the mobile terminal includes a memory and a processor.

Fig. 3 is a flowchart illustrating a first embodiment of a lock screen display method according to the present invention. In this embodiment, the execution order of the steps in the flowchart shown in fig. 3 may be changed and some steps may be omitted according to different requirements. The screen locking display method comprises the following steps:

step S301, when a screen-on instruction is detected, scene information of the mobile terminal is acquired to judge a scene corresponding to the mobile terminal.

Specifically, the context information includes one or more of time, location, power, network status, and motion status. In this embodiment, the context information includes all of the above parameters. Wherein, the time may include a plurality of time periods, such as dividing each day into 6: 00-12: 00. 12: 00-18: 00. 18: 00-24: 00. 24: 00-6: 00 for four time periods; the location may also include multiple locations, such as home, business, and locations other than home, business; similarly, the electric quantity may include various electric quantity ranges, the network state may include states such as non-networking, WiFi networking, GPRS networking, and the motion state may include states such as walking, still, running. Each combination of the above 5 parameters corresponds to a scene, and when the value or range of each parameter is determined, a unique scene can be determined. It should be noted that, this embodiment only exemplifies which parameters are included in the context information, and in the actual use process, the context information may further include other parameters, such as the temperature of the mobile terminal, the ambient brightness, and the like.

And step S302, searching the viewing probability of each type of display content under the scene according to the pre-established Bayesian network model.

Specifically, the display content on the screen locking interface is divided into several types, for example, the display content includes: the type A represents information such as time, date, weather and the like, the type B represents notification information, the type C represents a music player, the type D represents display of third-party shortcut information such as drips and the like, and the type E represents password input information; of course, in other embodiments, the type of content displayed may be other content, and is merely illustrated here. Because the behavior of the user viewing the content displayed on the lock screen interface has a certain association relationship with the contextual information of the mobile terminal, for example, when the user is in an early peak time and a motion state, it is likely that viewing the lock screen interface is for viewing time information, although the behavior of the user using the mobile terminal has a certain uncertainty, there is a certain association relationship between the uncertainty and many factors, for example, the behavior of the user using the mobile terminal may be associated with time, that is, the user is likely to frequently use the mobile terminal to perform a certain operation within a certain fixed time period or rarely use the terminal to perform a certain operation within a certain time period. Therefore, the Bayesian network model is established based on the influence of the contextual information on various types of display contents viewed by the user on the screen locking interface.

Preferably, the process of establishing the bayesian network model comprises the following steps: (1) firstly, a bayesian network model is established, where the bayesian network model is a network model representing an influence of the context information on each type of display content, please refer to fig. 7, fig. 7 is a bayesian network model representing an influence of the context information on each type of display content viewed by a user on a screen locking interface, as shown in fig. 7, in this embodiment, the context information includes time, position, electric quantity, network state and motion state, the display content on the screen locking interface is divided into A, B, C, D types, and under different contexts, a specific behavior of the user viewing the screen locking interface is a probability event with uncertainty, so that each edge in fig. 7 represents a probability value (i.e., viewing probability) representing a probability of a current context and a probability of occurrence of a related behavior; (2) setting initial probabilities of viewing the display contents of the respective types in the respective scenarios, in this embodiment, the setting of the initial probabilities is a process of initializing the bayesian network model, where the initial probabilities of viewing the display contents of the respective types in the respective scenarios are the same, and a sum of the initial probabilities is 1, for example: assuming that the combination mode of each parameter constituting the scenario information is n, that is, the mobile terminal has n scenarios, the initial probability of viewing each type of display content under each scenario is the same; (3) updating the initial probability according to user operation data to obtain the viewing probability of each type of display content under each scene; after the user establishes the initialized bayesian network model, in order to associate the bayesian network model with the behavior habits of the user, it is necessary to perform an update operation on the bayesian network model by using user operation data, where the user operation data is an operation record for the user to view a certain type of display content in a certain scenario. When the initial probability is updated through user operation data, the core method is as follows: if the number of times that the user views the display content of a certain type in a certain scene is large, the viewing probability that the user views the display content of the certain type in the scene is increased. More specifically, the step of updating the initial probability according to the user operation data includes: (31) detecting a scene corresponding to the user operation data and the type of display content viewed by the user; (32) increasing the initial probability of viewing the display content of the type under the scene by a preset value, and reducing the initial probability of viewing the display content of other types under the scene by the preset value; more specifically, the step of reducing the initial probability of viewing other types of display contents under the scenario by the preset value specifically includes: and respectively reducing the initial probability of viewing other types of display contents under the scene by a/(n-1), wherein a represents the preset value, and n represents the total number of types of the display contents. Such as: after the initialized Bayesian network model is established, if a user checks a screen locking interface after sending a screen lightening instruction to generate a piece of user operation data, and the user operation data is that the user checks the display content of the type A under the scene 1, the initial probability of the user checking the display content of the type A under the scene 1 is increased by a preset value a, and meanwhile, the initial probability of checking other types of display content under the scene 1 is respectively reduced by a/(n-1). It should be noted that, after the initial probability is updated to obtain the viewing probability, the subsequent user operation data is updated with the current viewing probability as the initial probability. When the amount of the user operation data reaches a certain degree, the viewing probability of each type of display content under each scene is associated with the user behavior.

In step S303, the display content with the highest viewing probability is set as the target display content.

In this embodiment, after the viewing probability of each type of display content in the current scene of the mobile terminal is found, the display content with the highest viewing probability is used as the target display content, where the target display content is used to represent the display content that the user is most likely to view in the current scene. When the display content with the maximum viewing probability is taken as the target display content, at least one type of display content with the maximum viewing probability may be taken as the target display content, and if it is assumed that the types of the display content include A, B, C, D, E, and the probabilities of viewing the types of display content in the current situation are found to be B, D, C, E, A in sequence from the largest to the smallest according to the bayesian network model, only one type of display content with the maximum viewing probability (i.e., the display content of type B) may be taken as the target display content, and of course, two types of display content with the maximum viewing probability (i.e., the display contents of types B and D) may also be taken as the target display content. Preferably, only one type of display content with the highest viewing probability is used as the target display content in the present embodiment.

And step S304, controlling the mobile terminal to display the target display content on a screen locking interface and only lightening a display area corresponding to the target display content.

Referring to fig. 8 and 9, fig. 8 is a schematic diagram of an embodiment of a screen locking interface in the prior art after a screen-up instruction is detected, fig. 9 is a schematic diagram of an embodiment of a screen locking interface in the present invention after a screen-up instruction is detected, in the embodiments shown in fig. 8 and 9, types of display contents include A, B, C, D, E, and probabilities that various types of display contents are checked in a current situation are found to be B, D, C, E, A in sequence from large to small according to a bayesian network model when a screen-up instruction is detected, at this time, only target display contents (i.e., display contents of type B) are displayed on the screen locking interface of the mobile terminal, and in order to avoid unnecessary power consumption, only a display area corresponding to the target display contents is lit up, while other areas on the screen remain black.

Through the steps S301 to S304, when the screen-up instruction is detected, the screen-up display method of the present invention obtains the context information of the mobile terminal to determine the context corresponding to the mobile terminal, then searches for the viewing probability of each type of display content under the context according to the pre-established bayesian network model, and uses the display content with the maximum viewing probability as the target display content, and finally controls the mobile terminal to display the target display content on the screen-up interface and only light up the display area corresponding to the target display content, thereby realizing that the display content that the user wants to browse is presumed according to the current context, and only the display content that the user wants to browse is displayed on the screen-up interface, realizing that the content that the user wants to browse is provided for the user more intuitively, improving the user experience, and simultaneously only lighting up the display area corresponding to the target display content without lighting up the whole screen, the power consumption of the mobile terminal is greatly reduced.

Further, based on the first embodiment, a second embodiment of the lock screen display method of the present invention is provided. Fig. 4 is a flowchart illustrating a second embodiment of a lock screen display method according to the present invention. In this embodiment, the execution order of the steps in the flowchart shown in fig. 4 may be changed and some steps may be omitted according to different requirements. The screen locking display method comprises the following steps:

step S401, when the screen-on instruction is detected, the scene information of the mobile terminal is obtained to judge the scene corresponding to the mobile terminal.

Step S402, determining whether the pre-established bayesian network model is valid, if the determination result is no, executing step S403, and if the determination result is yes, executing step S404.

In this embodiment, after the bright-screen instruction is detected and before the bayesian network model is used to infer the display content that the user wants to browse, the effectiveness of the bayesian network model needs to be judged first, and since the bayesian network model is updated according to the user operation data, when the user operation data is less, the obtained bayesian network model has great inaccuracy, and only when the user operation data is more, the obtained bayesian network model can better conform to the use habit of the user. In this embodiment, in order to ensure the validity of the bayesian network model, a time threshold is set, and when the statistical time of the user operation data reaches the time threshold, it is determined that the constructed bayesian network model is valid, and otherwise, it is determined that the constructed bayesian network model is invalid.

In step S403, all types of display contents are taken as the target display contents, and step S408 is performed. Specifically, when the bayesian network model is invalid, it is indicated that data associated with the use habits of the user is not obtained yet, and therefore, in order to avoid that only part of types of display contents are displayed and display contents desired to be browsed by the user are easily missed, all types of display contents are taken as target display contents, that is, a complete screen locking interface is displayed.

And S404, searching the viewing probability of each type of display content under the scene according to the pre-established Bayesian network model.

Step S405, normalization processing is performed on each of the viewing probabilities.

In this embodiment, after finding the viewing probability of each type of display content under the current scenario, normalization processing needs to be performed on each viewing probability, if the current scenario is assumed to be scenario 2, and the viewing probability of viewing each type of display content under scenario 2 is found to be: p (type a | scene 2) is 0.4, P (type B | scene 2) is 0.1, and P (type C | scene 2) is 0.1 … …, but if the types that can be displayed on the current lock screen interface are only type a and type B, the result after normalization is: p (type a | scene 2) is 0.4/(0.4+0.1) 0.8, and P (type B | scene 2) is 0.1/(0.4+0.1) 0.2.

Step S406, determining whether the maximum viewing probability after the normalization processing is greater than a preset probability threshold, if yes, executing step S407, and if no, executing step S403.

In this embodiment, a probability threshold (i.e., a preset probability threshold) is set, and only when the maximum viewing probability after normalization exceeds the preset probability threshold (e.g., 0.6), it is considered that the user's purposiveness is obvious, only the display content corresponding to the maximum viewing probability is displayed, and the display content of other types is not displayed, and the corresponding display area on the screen is not lit up, otherwise, if all the viewing probabilities do not exceed the preset probability threshold, all the types of display content are used as the target display content, i.e., the complete screen-locking interface is displayed.

Step S407, the display content corresponding to the maximum viewing probability after the normalization processing is taken as the target display content.

And step S408, controlling the mobile terminal to display the target display content on the screen locking interface and only lightening a display area corresponding to the target display content.

Through the steps S401 to S408, after detecting the screen-up instruction, the screen-locking display method of the present invention first obtains context information of the mobile terminal to determine a context corresponding to the mobile terminal, then determines whether the pre-established bayesian network model is valid, if not, takes all types of display contents as the target display contents, if so, searches the viewing probability of each type of display contents under the context according to the pre-established bayesian network model, and performs normalization processing on each viewing probability, then determines whether the maximum viewing probability after the normalization processing is greater than a preset probability threshold, if so, takes the display contents corresponding to the maximum viewing probability after the normalization processing as the target display contents, otherwise, takes all types of display contents as the target display contents, thereby realizing presuming the display contents that the user wants to view according to the current context, and only the display content that the user wants to browse is displayed on the screen locking interface, so that the content that the user wants to browse is provided for the user more intuitively, the user experience is improved, and meanwhile, only the display area corresponding to the target display content is lightened without lightening the whole screen, so that the power consumption of the mobile terminal is greatly reduced.

Meanwhile, the present invention also provides a mobile terminal, which includes a memory, a processor, and a lock screen display program 400 stored in the memory and operable on the processor.

Fig. 5 is a functional block diagram of a lock screen display procedure 400 according to a first embodiment of the present invention. In this embodiment, the lock screen display program 400 may be divided into one or more modules, and the one or more modules are stored in the memory 109 of the mobile terminal 100 and executed by one or more processors (in this embodiment, the controller 110) to implement the present invention. For example, in fig. 5, the lock screen display program 400 may be divided into a context information acquisition module 401, a viewing probability acquisition module 402, a target display content generation module 403, and a lock screen interface display module 404. The module referred to in the present invention refers to a series of computer program instruction segments capable of performing specific functions, and is more suitable than a computer program for describing the execution process of software in the mobile terminal 100. The detailed description of the functions of the

functional modules

401 and 404 will be described below. Wherein:

the context information acquiring module 401 is configured to acquire context information of the mobile terminal to determine a context corresponding to the mobile terminal when the bright screen instruction is detected. Specifically, the context information includes one or more of time, location, power, network status, and motion status. In this embodiment, the context information includes all of the above parameters. Wherein, the time may include a plurality of time periods, such as dividing each day into 6: 00-12: 00. 12: 00-18: 00. 18: 00-24: 00. 24: 00-6: 00 for four time periods; the location may also include multiple locations, such as home, business, and locations other than home, business; similarly, the electric quantity may include various electric quantity ranges, the network state may include states such as non-networking, WiFi networking, GPRS networking, and the motion state may include states such as walking, still, running. Each combination of the above 5 parameters corresponds to a scene, and when the value or range of each parameter is determined, a unique scene can be determined. It should be noted that, this embodiment only exemplifies which parameters are included in the context information, and in the actual use process, the context information may further include other parameters, such as the temperature of the mobile terminal, the ambient brightness, and the like.

The viewing probability obtaining module 402 is configured to find the viewing probability of each type of display content under the scenario according to a pre-established bayesian network model. Specifically, the display content on the screen locking interface is divided into several types, for example, the display content includes: the type A represents information such as time, date, weather and the like, the type B represents notification information, the type C represents a music player, the type D represents display of third-party shortcut information such as drips and the like, and the type E represents password input information; of course, in other embodiments, the type of content displayed may be other content, and is merely illustrated here. Because the behavior of the user viewing the content displayed on the lock screen interface has a certain association relationship with the contextual information of the mobile terminal, for example, when the user is in an early peak time and a motion state, it is likely that viewing the lock screen interface is for viewing time information, although the behavior of the user using the mobile terminal has a certain uncertainty, there is a certain association relationship between the uncertainty and many factors, for example, the behavior of the user using the mobile terminal may be associated with time, that is, the user is likely to frequently use the mobile terminal to perform a certain operation within a certain fixed time period or rarely use the terminal to perform a certain operation within a certain time period. Therefore, the Bayesian network model is established based on the influence of the contextual information on various types of display contents viewed by the user on the screen locking interface. Preferably, the process of establishing the bayesian network model comprises the following steps: (1) firstly, a bayesian network model is established, where the bayesian network model is a network model representing an influence of the context information on each type of display content, please refer to fig. 7, fig. 7 is a bayesian network model representing an influence of the context information on each type of display content viewed by a user on a screen locking interface, as shown in fig. 7, in this embodiment, the context information includes time, position, electric quantity, network state and motion state, the display content on the screen locking interface is divided into A, B, C, D types, and under different contexts, a specific behavior of the user viewing the screen locking interface is a probability event with uncertainty, so that each edge in fig. 7 represents a probability value (i.e., viewing probability) representing a probability of a current context and a probability of occurrence of a related behavior; (2) setting initial probabilities of viewing the display contents of the respective types in the respective scenarios, in this embodiment, the setting of the initial probabilities is a process of initializing the bayesian network model, where the initial probabilities of viewing the display contents of the respective types in the respective scenarios are the same, and a sum of the initial probabilities is 1, for example: assuming that the combination mode of each parameter constituting the scenario information is n, that is, the mobile terminal has n scenarios, the initial probability of viewing each type of display content under each scenario is the same; (3) updating the initial probability according to user operation data to obtain the viewing probability of each type of display content under each scene; after the user establishes the initialized bayesian network model, in order to associate the bayesian network model with the behavior habits of the user, it is necessary to perform an update operation on the bayesian network model by using user operation data, where the user operation data is an operation record for the user to view a certain type of display content in a certain scenario. When the initial probability is updated through user operation data, the core method is as follows: if the number of times that the user views the display content of a certain type in a certain scene is large, the viewing probability that the user views the display content of the certain type in the scene is increased. More specifically, the step of updating the initial probability according to the user operation data includes: (31) detecting a scene corresponding to the user operation data and the type of display content viewed by the user; (32) increasing the initial probability of viewing the display content of the type under the scene by a preset value, and reducing the initial probability of viewing the display content of other types under the scene by the preset value; more specifically, the step of reducing the initial probability of viewing other types of display contents under the scenario by the preset value specifically includes: and respectively reducing the initial probability of viewing other types of display contents under the scene by a/(n-1), wherein a represents the preset value, and n represents the total number of types of the display contents. Such as: after the initialized Bayesian network model is established, if a user checks a screen locking interface after sending a screen lightening instruction to generate a piece of user operation data, and the user operation data is that the user checks the display content of the type A under the scene 1, the initial probability of the user checking the display content of the type A under the scene 1 is increased by a preset value a, and meanwhile, the initial probability of checking other types of display content under the scene 1 is respectively reduced by a/(n-1). It should be noted that, after the initial probability is updated to obtain the viewing probability, the subsequent user operation data is updated with the current viewing probability as the initial probability. When the amount of the user operation data reaches a certain degree, the viewing probability of each type of display content under each scene is associated with the user behavior.

The target display content generating module 403 is configured to use the display content with the largest viewing probability as the target display content. In this embodiment, after the viewing probability of each type of display content in the current scene of the mobile terminal is found, the display content with the highest viewing probability is used as the target display content, where the target display content is used to represent the display content that the user is most likely to view in the current scene. When the display content with the maximum viewing probability is taken as the target display content, at least one type of display content with the maximum viewing probability may be taken as the target display content, and if it is assumed that the types of the display content include A, B, C, D, E, and the probabilities of viewing the types of display content in the current situation are found to be B, D, C, E, A in sequence from the largest to the smallest according to the bayesian network model, only one type of display content with the maximum viewing probability (i.e., the display content of type B) may be taken as the target display content, and of course, two types of display content with the maximum viewing probability (i.e., the display contents of types B and D) may also be taken as the target display content. Preferably, only one type of display content with the highest viewing probability is used as the target display content in the present embodiment.

The screen locking interface display module 404 is configured to control the mobile terminal to display the target display content on the screen locking interface and only light up a display area corresponding to the target display content. Referring to fig. 8 and 9, fig. 8 is a schematic diagram of an embodiment of a screen locking interface in the prior art after a screen-up instruction is detected, fig. 9 is a schematic diagram of an embodiment of a screen locking interface in the present invention after a screen-up instruction is detected, in the embodiments shown in fig. 8 and 9, types of display contents include A, B, C, D, E, and probabilities that various types of display contents are checked in a current situation are found to be B, D, C, E, A in sequence from large to small according to a bayesian network model when a screen-up instruction is detected, at this time, only target display contents (i.e., display contents of type B) are displayed on the screen locking interface of the mobile terminal, and in order to avoid unnecessary power consumption, only a display area corresponding to the target display contents is lit up, while other areas on the screen remain black.

Through the

module

401 and 404, when the screen-up instruction is detected, the screen-up display program of the present invention obtains the context information of the mobile terminal to determine the context corresponding to the mobile terminal, then searches the viewing probability of each type of display content under the context according to the pre-established bayesian network model, and uses the display content with the maximum viewing probability as the target display content, and finally controls the mobile terminal to display the target display content on the screen-up interface and only light up the display area corresponding to the target display content, thereby realizing that the display content which the user wants to browse is presumed according to the current context, and only the display content which the user wants to browse is displayed on the screen-up interface, realizing that the content which the user wants to browse is provided for the user more intuitively, improving the user experience, and only lighting up the display area corresponding to the target display content without lighting up the whole screen, the power consumption of the mobile terminal is greatly reduced.

Further, based on the above-mentioned first embodiment of the lock screen display program 400 of the present invention, a second embodiment of the lock screen display program 400 of the present invention is proposed. Referring to fig. 6, fig. 6 is a functional block diagram illustrating a screen locking display program 400 according to a second embodiment of the present invention, wherein compared with the first embodiment, the screen locking display program 400 further includes an effectiveness determining module 405, a full screen display module 406, a normalizing module 407, and a probability threshold determining module 408.

The full screen display module 406 is configured to use all types of display contents as the target display contents. Specifically, when the bayesian network model is invalid, it is indicated that data associated with the use habits of the user is not obtained yet, and therefore, in order to avoid that only part of types of display contents are displayed and display contents desired to be browsed by the user are easily missed, all types of display contents are taken as target display contents, that is, a complete screen locking interface is displayed.

The normalization module 407 is configured to perform normalization processing on the found viewing probabilities before the target display content generation module 403 executes. In this embodiment, after finding the viewing probability of each type of display content under the current scenario, normalization processing needs to be performed on each viewing probability, if the current scenario is assumed to be scenario 2, and the viewing probability of viewing each type of display content under scenario 2 is found to be: p (type a | scene 2) is 0.4, P (type B | scene 2) is 0.1, and P (type C | scene 2) is 0.1 … …, but if the types that can be displayed on the current lock screen interface are only type a and type B, the result after normalization is: p (type a | scene 2) is 0.4/(0.4+0.1) 0.8, and P (type B | scene 2) is 0.1/(0.4+0.1) 0.2.

The probability threshold determination module 408 is configured to determine whether the maximum viewing probability after the normalization processing is greater than a preset probability threshold, if the determination result is yes, execute the target display content generation module 403, and if the determination result is no, execute the full screen display module 406. In this embodiment, a probability threshold (i.e., a preset probability threshold) is set, and only when the maximum viewing probability after normalization exceeds the preset probability threshold (e.g., 0.6), it is considered that the user's purposiveness is obvious, only the display content corresponding to the maximum viewing probability is displayed, and the display content of other types is not displayed, and the corresponding display area on the screen is not lit up, otherwise, if all the viewing probabilities do not exceed the preset probability threshold, all the types of display content are used as the target display content, i.e., the complete screen-locking interface is displayed. At this time, in this embodiment, the target display content generating module 403 specifically uses the display content corresponding to the maximum viewing probability after the normalization processing as the target display content.

Through the module 401 and 408, after detecting the screen-up instruction, the screen-locking display program provided by the present invention first obtains the context information of the mobile terminal to determine the context corresponding to the mobile terminal, then determines whether the pre-established bayesian network model is valid, if not, takes all types of display contents as the target display contents, if so, searches the viewing probability of each type of display contents under the context according to the pre-established bayesian network model, and performs normalization processing on each viewing probability, then determines whether the maximum viewing probability after the normalization processing is greater than the preset probability threshold, if so, takes the display contents corresponding to the maximum viewing probability after the normalization processing as the target display contents, otherwise, takes all types of display contents as the target display contents, thereby realizing the presumption of the display contents that the user wants to view according to the current context, and only the display content that the user wants to browse is displayed on the screen locking interface, so that the content that the user wants to browse is provided for the user more intuitively, the user experience is improved, and meanwhile, only the display area corresponding to the target display content is lightened without lightening the whole screen, so that the power consumption of the mobile terminal is greatly reduced.

In addition, the present invention further provides a computer-readable storage medium, wherein a lock screen display program is stored on the computer-readable storage medium, and when being executed by a processor, the lock screen display program implements the steps of the lock screen display method described in fig. 3 to 4.
