Technical Field

[0001] The present invention relates to the technical field of intelligent device interaction, and particularly relates to an interaction method and system between a tablet computer and a mobile phone. Background Art

[0002] With the rapid development of mobile Internet technology, tablet computers and mobile phones, as the main intelligent mobile devices, have become indispensable information interaction tools in people's daily lives. However, during the interaction between tablet computers and mobile phones, users often encounter a series of problems, which not only affect the fluency and efficiency of the interaction, but also reduce the user experience.

[0003] During the process of users interacting with tablet computers and mobile phones, for commonly used interaction software, due to the tablet computer and the mobile phone may use different operating systems or software versions, version incompatibility may occur during the interaction. Software update is the key to ensuring interaction efficiency. However, existing devices or systems often cannot accurately determine whether the versions of the interaction software on both ends of the interaction need to be synchronized. During the interaction, users usually have a fixed usage pattern for the interaction software, including startup time and usage duration. Existing systems are difficult to accurately predict these time information, and cannot combine the version synchronization information of the interaction software at both ends of the interaction with the predicted user usage pattern to select the update timing for users, resulting in the update of the interaction software affecting the normal use of users, reducing the interaction efficiency and quality between the tablet computer and the mobile phone, and affecting the user experience.

[0017] To enable those skilled in the art to better understand the solution of the present invention, the following will clearly and completely describe the technical solution in the embodiments of the present invention in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0018] Embodiment 1: Figure 1 It is a flowchart of an interaction method between a tablet computer and a mobile phone provided in Embodiment 1 of the present invention. The embodiments of the present invention are applicable to the situation of using a tablet computer and a mobile phone for interaction. An interaction method between a tablet computer and a mobile phone can be executed by an interaction system between a tablet computer and a mobile phone.

[0019] As Figure 1 shown, an interaction method between a tablet computer and a mobile phone provided in an embodiment of the present invention specifically includes the following steps:

[0020] S1. Obtain the historical usage data of the interaction between the tablet computer and the mobile phone. The historical usage data includes the software for interaction between the tablet computer and the mobile phone, the interaction usage duration of the software, and the interaction start time. Analyze the historical usage data to obtain an interaction importance value, and mark the interaction software as important interaction software or unimportant interaction software based on the interaction importance value;

[0021] Specifically, obtain the software used when the tablet computer and the mobile phone interact through the device background record, and mark it as the interaction software. Obtain the interaction usage duration of the interaction software within the historical period. The historical period represents a time period starting from the time node when the tablet computer and the mobile phone first interact and ending at the current system time node;

[0022] Based on any interaction software, perform a ratio processing on the interaction usage duration of the interaction software and the historical period duration to obtain the interaction duration ratio of the interaction software, marked as KX;

[0023] Obtain the difference between the current system time and the most recent interaction start time of the interaction software, and perform a ratio processing on the obtained interaction non-start duration and the historical period duration to obtain the non-start duration ratio of the interaction software, marked as KY;

[0024] Perform data processing on the obtained interaction duration ratio KX and non-start duration ratio KY, and obtain the interaction importance value DT through the formula where a1 and a2 are both preset proportionality coefficients, where a1 = 2.314 and a2 = 1.217;

[0025] It should be noted that the purpose of the interaction importance value DT is to analyze the interaction usage duration and non - startup duration of the user with the interaction software on the tablet computer and mobile phone, and then analyze the interaction usage situation of the user with the interaction software, and judge the importance degree of the interaction software to the user. The larger the interaction importance value, the more the interaction usage duration of the interaction software or the shorter the time since the last interaction usage, and the higher the importance degree of the interaction software to the user;

[0026] Exemplarily, the total duration from the first interaction between the tablet computer and the mobile phone to the current system time is 100 hours, that is, the historical cycle duration = 100 hours. The interaction usage duration of this interaction software within the historical cycle is 30 hours, and the difference between the current system time and the latest interaction startup time of this software is 20 hours. Calculate the interaction duration ratio as 0.3 and the non - startup duration ratio as 0.2, and calculate the interaction importance value DT of this interaction software as 2.5417;

[0027] Compare the obtained interaction importance value with the interaction importance threshold;

[0028] If the interaction importance value of the interaction software is less than or equal to the interaction importance threshold, mark the interaction software as an unimportant interaction software;

[0029] If the interaction importance value of the interaction software is greater than the interaction importance threshold, mark the interaction software as an important interaction software;

[0030] S2. Based on the marked important interaction software, obtain the interaction startup time of the important interaction software, count the interaction startup time to obtain an interaction startup time group, and analyze the interaction startup time group according to the historical usage data to obtain the expected startup time and the corresponding expected usage duration of the interaction software;

[0031] Specifically, based on any important interaction software, obtain the interaction startup time of the interaction software between the tablet computer and the mobile phone every day within the historical cycle, take the absolute value of the difference between any two interaction startup times, and obtain the startup time difference between the two interaction startup times;

[0032] Compare the startup time difference between the two interaction startup times with the startup time difference threshold:

[0033] If the startup time difference between the two interaction startup times is less than the startup time difference threshold, then classify the two interaction startup times into an interaction startup time group;

[0034] If the startup time difference between the two interaction startup times is greater than or equal to the startup time difference threshold, do not perform any processing on it;

[0035] Perform the above operations on all interaction start times within the historical period until there is no start time difference between interaction start times less than the start time difference threshold. If there is an interaction start time that has not been grouped into any interaction start time group at this time, then this interaction start time itself forms an interaction start time group;

[0036] It should be noted that the purpose of the above steps is to group interaction start times that are close in time within the historical period into one interaction start time group, facilitating subsequent statistical analysis of a large number of interaction start times;

[0037] Based on any interaction start time group, obtain the number of interaction start times in the interaction start time group, and perform a ratio process with the total number of all interaction start times within the historical period to obtain the common coefficient of the interaction start time group;

[0038] Compare the obtained common coefficient with the common coefficient threshold;

[0039] If the common coefficient of the interaction start time group is less than or equal to the common coefficient threshold, it indicates that the number of times the user interacts with the interaction software within the time range covered by the interaction start time group is small;

[0040] If the common coefficient of the interaction start time group is greater than the common coefficient threshold, it indicates that the number of times the user interacts with the interaction software within the time range covered by the interaction start time group is large, and mark the interaction start time group as a common time group;

[0041] Based on the obtained common time group, obtain all the interaction start times included in the common time group, sum them up and take the average to obtain the expected start time of the interaction software;

[0042] Obtain the interaction usage durations corresponding to all the interaction start times included in the common time group, conduct a comparative analysis on them, and take the maximum interaction usage duration among them to obtain the expected usage duration corresponding to the expected start time;

[0043] It should be noted that there may not be only one expected start time for important interaction software. The user can interact with the tablet and the mobile phone multiple times in a day;

[0044] S3. Obtain the version numbers of the important interaction software on the tablet and the mobile phone at both ends of the interaction, compare and determine whether the version numbers are the same. If they are not the same, then obtain the update data. The update data includes the size of the update package required to update the old version of the interaction software to the new version and the current network speed of the update device, and process the update data to obtain the estimated update duration;

[0045] Based on any important interaction software, obtain the version numbers of the important interaction software on the tablet and the mobile phone at both ends of the interaction and compare them;

[0046] If the version numbers of the interactive software are the same, no processing is performed;

[0047] If the version numbers of the interactive software are different, an update prediction signal is generated;

[0048] Based on the generated update prediction signal, for different version numbers of the same interactive software on the tablet and mobile phone at both ends of the interaction, obtain the size of the update package required to update the old version of the interactive software to the new version, and uniformly convert its unit to MB (megabyte);

[0049] Obtain the device where the old version of the interactive software is located, obtain the current network speed of the device, and uniformly convert its unit to MBps (megabyte per second);

[0050] Calculate the estimated update time TS through the formula: estimated update duration = update package size (MB) / current network speed (MBps), and its unit is seconds (s);

[0051] Convert the obtained estimated update duration to a duration represented by hours (h), minutes (min), and seconds. Exemplarily, if the obtained estimated update duration is 5421 s, it is converted to 1 h 30 min 21 s; if the obtained estimated update duration is 1834 s, it is converted to 30 min 34 s;

[0052] S4. Based on the obtained estimated update duration and the expected start time, determine whether there is an interactive software update period within a day that does not affect the normal interaction and use of the user. If so, calculate the expected update time. If not, generate an immediate update prompt signal, and give the user an update reminder according to the obtained expected update time or the immediate update prompt signal;

[0053] Based on any important interactive software, determine whether the important interactive software is in use. If it is in use, do not perform any operation. If the software is not in use, obtain all the expected start times within the next day of the current system time and sort them in chronological order;

[0054] Obtain the expected start time closest to the current time, mark it as the first expected start time, and calculate the interval between the first expected start time and the current time, mark it as the first interval duration;

[0055] Based on any two adjacent expected start times, calculate the interval between the adjacent expected start times, mark it as the second interval duration, obtain the expected usage duration corresponding to the previous expected start time between the adjacent expected start times, and perform a difference operation on the second interval duration and the expected usage duration to obtain the second actual interval duration;

[0056] Based on any important interactive software, compare the estimated update duration of the important interactive software with the first interval duration;

[0057] If the first interval duration is greater than the expected update duration, an update needs to be performed before the first expected start time, and the expected update time = the first expected start time - the expected update duration;

[0058] If the first interval duration is less than or equal to the expected update duration, then compare the second actual interval duration between the first expected start time and its adjacent expected start time with the expected update duration:

[0059] If the second actual interval duration is greater than the expected update duration, an update needs to be performed before the subsequent expected start time between the adjacent expected start times, and the expected update time = the subsequent expected start time - the expected update duration;

[0060] If the second actual interval duration is less than or equal to the expected update duration, continue to search backward until a second actual interval duration that meets the conditions is found or there is no next expected start time;

[0061] If there is no next expected start time, mark the expected update time as an immediate update;

[0062] It should be noted that the purpose of the above steps is to prevent the update of the old version of the interactive software from affecting the normal use of users. The purpose of updating the old version of the interactive software is to synchronize the versions of the interactive software on the interactive devices at both ends and improve the interaction efficiency and quality between the two ends of the interaction;

[0063] Generate an update reminder for the user based on the above steps. If the user agrees to update, start the update of the old version of the interactive software at the obtained expected update time;

[0064] The technical solution of the embodiment of the present invention is as follows: Obtain the historical usage data of the interaction between the tablet computer and the mobile phone, analyze the historical usage data to obtain the interaction importance value, and mark the interactive software as important interactive software or unimportant interactive software based on the interaction importance value; obtain the interaction start time of the important interactive software, count the interaction start time to obtain the interaction start time group, analyze the interaction start time group according to the historical usage data to obtain the expected start time and the corresponding expected usage duration of the interactive software, obtain the version numbers of the important interactive software on the tablet computer and the mobile phone at both ends of the interaction, compare and judge whether the version numbers are the same. If they are different, obtain the update data, process the update data to obtain the expected update duration; perform data analysis on the obtained expected update duration and the expected start time to obtain the expected update time, and give an update reminder to the user according to the obtained expected update time to improve the interaction efficiency and quality between the tablet computer and the mobile phone.

Analyze the historical usage data to obtain an interaction importance value, and based on the interaction importance value, mark the interaction software as important interaction software or unimportant interaction software respectively;

[0068] Update analysis and prediction module: Obtain the version numbers of the important interaction software on both ends of the interaction, namely the tablet computer and the mobile phone, compare and judge whether the version numbers are the same. If they are not the same, obtain the update data. The update data includes the update package size required to update the old version of the interaction software to the new version and the current network speed of the update device, and process the update data to obtain the estimated update duration;

[0069] User update reminder module: Perform data analysis on the obtained estimated update duration and the expected start time to obtain the expected update time, and give a user update reminder according to the obtained expected update time.

The preset parameters in the formulas are set by those skilled in the art according to the actual situation.

[0071] The above has described an embodiment of the present invention in detail, but the content described is only the preferred embodiment of the present invention and cannot be considered as limiting the scope of implementation of the present invention. All equivalent changes and improvements made according to the scope of the present invention application should still fall within the scope covered by the patent of the present invention.
