Detailed ways

The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application.

Firstly, a patch system 10 and how to upgrade the application program "APP-1" using patches in the patch system 10 will be introduced with reference to FIG. 1 .

As shown in FIG. 1 , the patch system 10 may include a server 100, a router 101, and multiple terminal devices such as a mobile phone 102, a smart bracelet 103, a smart earphone 104, a smart speaker 105, a smart TV 106, and a computer 107. Among them, the router 101 can set up a wireless network and transmit wireless network signals, and terminal devices such as mobile phones 102, smart bracelets 103, smart earphones 104, smart speakers 105, smart TVs 106, computers 107, etc. can connect to the wireless network of the router 101 and server 100 communications.

As shown in FIG. 1 , multiple terminal devices in the patch system 10 may have different versions of the application program "APP-1" installed. Among them, specifically, the version of "APP-1" on the mobile phone 102 is "2.0.0", and the size of the patch 1 adapted to it is 20M; 0", the size of patch 2 adapted to it is 2M; the version of "APP-1" on the smart earphone 104 is "4.0.0", and the size of patch 3 adapted to it is 800K; the size of "APP-1" on the smart speaker 105 is The version of "1" is "5.0.0", and the size of patch 4 is 1M; the version of "APP-1" on the smart TV 106 is "6.0.0", and the size of patch 5 is 50M; The version of "APP-1" on the computer 107 is "7.0.0", and the patch 6 adapted to it has a size of 40M.

In the patch system 10, when the server 100 detects that the "APP-1" on the smart earphone 104 needs to be upgraded, first, the server 100 can send the "APP-1 4.0.0 for Patch 3 of "Smart Headphones", the size of patch 3 is 800K. Next, the smart earphone 104 can directly download patch 3 to upgrade the application program "APP-1" from "APP-1 4.0.0 for smart earphones" to "APP-1 4.1.0 for smart earphones". The process of "APP-1" on other terminal devices upgrading "APP-1" with a patch can be similar to the process of "APP-1" on the smart earphone 104 directly downloading patch 3 for upgrading.

It can be seen from FIG. 1 that since the versions of "APP-1" on different terminal devices are different, the patches issued by the server 100 to adapt to "APP-1" on each terminal device will also be different. , which will cause the server 100 to send multiple patch packages adapted to different terminal devices to the terminal device that needs to be upgraded, the amount of data transmission is very large, and the network burden is serious.

As shown in FIG. 2 , the embodiment of the present application provides a patch system 20 and a patch method implemented in the patch system. In the patch system 20 shown in FIG. 2 , a terminal device with strong computing processing capability and sufficient storage capability, such as the mobile phone 102, can be used as a "super terminal". "Hyper Terminal" can use the smaller differential data sent by the server 100 to restore a patch package suitable for the target device (such as smart earphone 104, etc.), and then "Hyper Terminal" sends the restored patch package to The target device, so that the server 100 does not need to directly transmit patch packages with a large amount of data to each terminal device, thereby reducing the amount of data transmission and reducing the burden on the network.

As exemplarily shown in FIG. 2 , the patch system 20 provided by the embodiment of the present application may include: a server 100 and terminal devices such as a mobile phone 102 , a smart bracelet 103 , and a smart earphone 104 . The mobile phone 102, the smart bracelet 103 and the smart earphone 104 can be in the same local area network by accessing the same Wi-Fi access point provided by the router 101. The mobile phone 102, the smart bracelet 103, the smart earphone 104 and other terminal devices can all be installed with an application program "APP-1". Among them, the version of "APP-1" in the mobile phone 102 is 2.0.0, the version of "APP-1" in the smart bracelet 103 is 3.0.0, and the version of "APP-1" in the smart earphone 104 is 4.0 .0.

In the patch system 20, taking upgrading the "APP-1" installed on the smart earphone 104 as an example, the patch method provided in the embodiment of the present application may include the following steps:

Step 1. The server 100 can prepare the patch 3 required for upgrading the "APP-1" of the smart earphone 104, and its size can be, for example, 800K.

Step 2. The server 100 determines the most relevant device from all the terminal devices connected to it. In this example, the most relevant devices may be a mobile phone 102 and a smart bracelet 103, and the mobile phone 102 is selected as the most relevant device because "APP-1 2.0.0" on the device has a software module that highly overlaps with patch 3, The smart bracelet 103 was also selected as the most relevant device because the "APP-1 3.0.0" on the device has a software module that highly overlaps with Patch 3.

Step 3. The server 100 can use the "APP-1" on the most relevant device (i.e. the mobile phone 102 and the smart bracelet 103) (specifically, it can refer to some modules that highly overlap with the patch 3) and the patch 3 to generate differential data C, Its size can be 50K, which is significantly smaller than the size of patch 3.

Step 4. The server 100 can send the differential data C to the mobile phone 102, and inform the mobile phone 102 of the target device (ie, the smart earphone 104) and the most relevant device.

Step 5, the mobile phone 102 can use the differential data C and the "APP-1" on the most relevant device (specifically, it can refer to some modules that are highly overlapped with the patch 3) to restore the patch 3, and then the mobile phone 102 can send the smart earphone 104 (that is, the target device) sends the restored patch 3 .

Step 6. The smart earphone 104 can use the patch 3 of the mobile phone 102 to upgrade "APP-1", specifically, "APP-1" can be upgraded from the old version 4.0.0 to the new version 4.1.0.

It can be seen that since the patch system 20 provided by the embodiment of the present application has the role of "hyper terminal", the server 100 does not need to directly transmit patches with a large amount of data to each terminal device, but only needs to transmit patches to the "hyper terminal" Utilize small differential data compared to the amount of data generated by the patch pack and the application on the most relevant device.

Further, the "Hyper Terminal" can use the differential data and the application program on the most relevant device to restore the patch package, and transmit the patch package to the target device, so as to finally realize the application program upgrade on the target device. This patch technology obviously reduces the amount of data transmission between the server and each terminal device when the application program on each terminal device is upgraded.

In the above patch technology, how to determine the most relevant device, how to generate differential data, and how to use the differential data to restore a patch package will be described in detail below.

1. How to determine the most relevant equipment

In this embodiment of the present application, the most relevant device may refer to a terminal device on which "APP-1" has one or more software modules highly overlapping with patch 3. For any patch, one most relevant device may be determined, or multiple most relevant devices may be determined. In the patch system 20 shown in FIG. 2 , any terminal device may become the most relevant device for patch 3 .

FIG. 3A exemplarily shows the software architecture of "APP-1" and Patch 3 on terminal devices such as mobile phone 102, smart bracelet 103, smart speaker 105 and the like.

As shown in Figure 3A, Patch 3 and "APP-1" on each terminal device can be divided into three software modules: FA1interface code, Entrylegcy code and FA1 code according to their software architecture, among which the FA1 interface code software module can be used to implement the interface layer The specific logical structure, the Entrylegcy code software module can be used to realize the compatibility processing function of the software data system, and the FA1 code module can be used to realize the Hongmeng card function of the application program. Each software module may be composed of multiple methods and variables, and the composition of the same software module on different terminal devices and patches may be different.

For example, as shown in Figure 3A, the FA1 interface code software module in the patch 3 can include the following variables: variable 1-a, variable 1-b, variable 1-c, variable 1-d, and the following methods: method 1-a, Method 1-b, Method 1-c, Method 1-d. The FA1 interface code software module in the "APP-1" on the mobile phone 102 can include the following variables: variable 1-a, variable 1-b, variable 1-c, variable 1-d, variable 1-e, variable 1-f , and the following methods: Method 1-a, Method 1-b, Method 1-c, Method 1-d, Method 1-e, Method 1-f. The FA1 interface code software module in the "APP-1" on the smart bracelet 103 can include the following variables: variable 1-d, variable 1-e, variable 1-f, and the following methods: method 1-d, method 1- e. Method 1-f. The FA1 interface code software module in the "APP-1" on the smart speaker 105 can include the following variables: variable 1-e, variable 1-f, variable 1-g, and the following methods: method 1-e, method 1-f , Method 1-g. Similar variables and methods that may be included in Patch 3 and other modules of various other terminal devices are shown in FIG. 3A , and will not be repeated here.

It can be seen that the FA1 interface code (02) module of "APP-1" on the mobile phone 102 has the highest overlap with the FA1 interface code (01) module in patch 3, and has the same variables as follows: variable 1-a, variable 1-b, variant 1-c, variant 1-d, and the same method with the following: method 1-a, method 1-b, method 1-c, method 1-d.

The entrylegcy code (03) module of "APP-1" on the smart bracelet 103 and the entrylegcy code (01) module in patch 3 have the highest coincidence degree, and have the same variables as follows: variable 2-b, variable 2-c, Variable 2-g, and has the same methods as: method 2-b, method 2-c, method 2-g.

The FA1 code (03) module of "APP-1" on the smart bracelet 103 and the FA1 code (01) module in patch 3 have the highest coincidence degree, and have the same variables as follows: variable 3-a, variable 3-b, Variable 3-g, and has the same methods as: method 3-a, method 3-b, method 3-g.

The coincidence degree=(the number of the same method+the number of the same variable)/(the total number of methods+the total number of variables).

Therefore, the most relevant to the FA1 interface code module of patch 3 is the FA1 interface code module in the "APP-1" of the mobile phone 102, and the most relevant to the Entrylegcy code module of patch 3 is the "APP-1" module of the smart bracelet 103. The Entrylegcy code module in "APP-1" has the greatest correlation with the FA1 code module of Patch 3 is the FA1 code module in "APP-1" of the smart bracelet 103.

As mentioned above, the codes in the three modules of different software versions of "APP-1" of different terminal devices have similarities and differences. By using the method of calculating correlation, the three modules of patch 3 and the codes on all terminal devices are obtained. The correlation size of the module corresponding to the name of "APP-1", select the module of "APP-1" that has the greatest correlation with the three modules of Patch 3, which is the most relevant module, and the terminal device where the most relevant module is located is most relevant equipment.

In the embodiment of the present application, there are two methods for calculating the correlation in order to determine the most relevant device:

The first method is to calculate the coupling coefficient, that is, to reversely analyze the module software code, obtain multiple variables and methods in the corresponding code segment, and perform structural analysis. The coupling coefficient is calculated as follows:

Coupling coefficient = (change in the number of variables + change in the number of methods) / (number of methods + number of variables)

Calculate the coupling coefficient with a single software module as the unit, select the module with the smallest coupling coefficient or the highest coincidence degree as the most relevant module, and the terminal device where the module is located is the most relevant device;

Furthermore, the methods and variables in each software module can also be divided into methods and variables of two dimensions, namely the platform dimension and the application dimension. The methods and variables of the platform dimension are divided into methods and variables based on the only difference of the terminal device. , the methods and variables of the application dimension are divided into methods and variables based on the only difference of the application program. How to determine the most relevant device in two dimensions will be described with reference to FIG. 3A .

When determining the most relevant device, the priority of the methods and variables on the platform dimension and the methods and variables on the application dimension can be distinguished.

For example, if the priority of the platform dimension is higher than the priority of the application dimension, then firstly determine which devices have software modules highly overlapping with patch 3 based on the methods and variables of the platform dimension.

In the step 2 shown in Figure 3A about determining the most relevant device method diagram, it is assumed that the variable 1-d and method 1-d in the FA1 interface code (01) module in patch 3 are the variables and methods of the platform dimension, and the variable 1-a , variable 1-b, variable 1-c and method 1-a, method 1-b, method 1-c are the variables and methods of the application dimension; the FA1 interface in the version 2.0.0 of "APP-1" on the mobile phone 102 Variable 1-d and method 1-d in the code(02) module are variables and methods of the platform dimension, variable 1-a, variable 1-b, variable 1-c, variable 1-e, variable 1-f and method 1 -a, method 1-b, method 1-c, method 1-e, method 1-f are the variables and methods of the application dimension; the variables in the FA1 interface code (03) module in version 3.0.0 of "APP-1" 1-d and method 1-d are variables and methods of the platform dimension, and variables and methods of variable 1-e, variable 1-f, method 1-e, and method 1-f are variables and methods of the application dimension.

Then we can know that in the platform dimension, the coupling coefficient between the FA1 interface code (01) module in patch 3 and the FA1 interface code (02) module in version 2.0.0 of the "APP-1" on the mobile phone 102 is zero, and the same , the coupling coefficient between the FA1 interface code (01) module in patch 3 and the FA1 interface code (03) module in version 3.0.0 of "APP-1" is also zero, that is, the two in the platform dimension and FA1 in patch 3 The coupling coefficients of the interface code(01) modules are equal. In this case, the coupling coefficient calculation on the application dimension is performed to obtain the module with the smallest coupling coefficient with the FA1 interface code(01) module in patch 3, so as to determine the most relevant Devices, which are calculated similarly to the platform dimension.

On the contrary, if the priority of the application dimension is higher than the priority of the platform dimension, then first determine which devices have software modules that have a high overlap with patch 3 based on the methods and variables of the application dimension. The calculation is similar to that shown above. If the coupling coefficient of a module on two devices calculated on the application dimension is equal to that of a module in patch 3, then the coupling coefficient calculation on the platform dimension is performed to determine the most relevant device.

It is not limited to determining the most relevant device by using the method and the coupling coefficient of the variables described above. In the embodiment of the present application, the binary code of the software module may also be used to determine the most relevant device.

The second method is to use binary to perform correlation calculation on the module software code (including but not limited to the bsdiff algorithm). The following is the correlation coefficient size of the corresponding module in the "APP-1" of the first embodiment patch 3 and each terminal device:

The correlation coefficient calculated by the FA1 interface code module of patch 3 and the FA1 interface code module of "APP-1" in the mobile phone 102 is 0.8, and the Entry Legcycode module of patch 3 and the Entry Legcycode of "APP-1" in the mobile phone 102 The correlation coefficient calculated by the module is 0.4, and the correlation coefficient calculated by the FA1 code module of patch 3 and the FA1 code module of "APP-1" in the mobile phone 102 is 0.2;

The correlation coefficient calculated by the FA1 interface code module of Patch 3 and the FA1 interface code module of "APP-1" in the smart bracelet 103 is 0.7, and the Entry Legcycode module of Patch 3 and the "APP-1" in the smart bracelet 103 The correlation coefficient calculated by the Entry Legcycode module of "is 0.7, and the correlation coefficient calculated by the FA1 code module of patch 3 and the FA1 code module of "APP-1" in the smart bracelet 103 is 0.6;

The correlation coefficient calculated between the FA1 interface code module of patch 3 and the FA1 interface code module of "APP-1" in the smart speaker 105 is 06, and the correlation coefficient between the Entry Legcycode module of patch 3 and the "APP-1" in the smart speaker 105 is 06. The correlation coefficient calculated by the Entry Legcycode module is 0.6, and the correlation coefficient calculated by the FA1 code module of patch 3 and the FA1 code module of "APP-1" in the smart speaker 105 is 0.5;

It can be known from the above correlation coefficient that the correlation coefficient between the FA1 interface code (02) in the "APP-1" of the mobile phone 102 and the FA1 interface code (01) in the patch 3 is at most 0.8, and the "APP-1" of the smart earphone 104 is 0.8. The correlation coefficient between EntryLegacycode (03) in "EntryLegacycode (03) and EntryLegacycode (01) in Patch 3 is at most 0.7, and the correlation coefficient between FA1 code (03) in "APP-1" of smart earphone 104 and FA1 code (01) in Patch 3 The maximum coefficient of sex is 0.6. Then it can be determined that the most relevant devices for patch 3 are the mobile phone 102 and the smart earphone 104 .

In Step 3 shown in FIG. 3B about how to obtain differential data, it can be seen that on the server 100, the differential data C is obtained by the software module on the most relevant device (FA1 interface code (02 shown in FIG. 3B ) ) module, Entrylegcy code (03) module and FA1 code (03) module) and Patch 3 are obtained by making differences based on the principle of removing common ground while reserving differences. Differential data C also has the same software architecture as patch 3 and "APP-1" on each terminal device, that is, it also includes three modules: FA1 interface code, Entrylegcy code and FA1 code.

2. How to generate differential data

FIG. 3B exemplarily shows specific operations on how to generate differential data C. As shown in FIG. As shown in Figure 3B, the methods and variables within the gray dotted lines in each module are the methods and variables discarded after the difference, and the remaining methods and variables are the methods and variables retained after the difference.

It can be seen that the FA1 interface code (00) module is generated by the difference between the FA1 interface code (01) module in the patch 3 and the FA1 interface code (02) module in the "APP-1 2.0.0" of the mobile phone 102, and the Entrylegcy code The (00) module is generated by the difference between the Entry legcy code (01) module in patch 3 and the Entrylegcy code (03) module in the "APP-1 3.0.0" of the smart bracelet 103, and the FA1 code (00) module is generated by The FA1 code(01) module in Patch 3 and the FA1 code(03) module in the "APP-1 3.0.0" of smart bracelet 103 are generated by difference.

From the above content, it can be known that the differential data C obtained in this way is the smallest differential data volume, and the size is only 50K, so that when the server 100 transmits the differential data C to the mobile phone 102, the transmitted data volume is the smallest and the transmission efficiency is the highest. , which can improve the efficiency of patches to fix urgent problems.

3. How to restore the patch

In the method diagram of how to restore patch 3 in step 4 shown in FIG. 3C, it can be seen that in the mobile phone 102, each module in the differential data C is the most relevant module of the "APP-1" of the most relevant device (Fig. 3C shows the FA1 interface code (02) module, the Entrylegcy code (03) module and the FA1 code (03) module) to restore patch 3 according to the principle of removing common differences while reserving differences. The principle of removing common differences while reserving differences is to discard differential data C and The most relevant modules have common variables and methods, and the unique variables and methods of differential data C and the unique variables and methods of the most relevant modules are reserved. The methods and variables within the gray dotted line in each module are the methods and variables discarded after restoration, and the remaining methods and variables are the methods and variables retained after restoration.

Specifically, the FA1 interface code (01) module is the FA1 interface code (02) module in the smart phone 102 and the FA1 interface code (00) module in the differential data C and discards the shared variable 1-e, variable 1-f and method 1-e, method 1-f, leave the unique variable 1-a, variable 1-b, variable 1-c, variable 1-d and method 1-a, method 1-b unique to the FA1 interface code (02) module , method 1-c, method 1-d;

The Entrylegcy code (01) module is the Entrylegcy code (03) module in the smart bracelet 103 and the Entrylegcy code (00) module in the differential data C. Abandon the shared variable 2-h and method 2-h, and leave the Entrylegcy code (03) Module unique variable 2-b, variable 2-c, variable 2-g and method 2-b, method 2-c, method 2-g and Entrylegcy code (00) module unique variable 2-f and method 2 -f;

The FA1 code(01) module discards the common variable 3-h and method 3-h for the FA1 code(03) module in the smart bracelet 103 and the FA1 code(00) module in the differential data C, leaving the FA1 code(03 ) module unique variable 3-a, variable 3-b, variable 3-g and method 3-a, method 3-b, method 3-g and FA1 code(00) module unique variable 3-d and method 3-d.

It can be understood that the implementation scenario in FIG. 2 is only for illustrating the embodiment of the present application, and does not constitute any limitation to the present application.

FIG. 4 shows a method flow of a patch method provided by an embodiment of the present application. Specifically, the following steps may be included:

S101 , the server side detects whether the "APP-1" of the terminal device under the server 100 needs to issue a patch, and determines that a patch 3 needs to be issued to the "APP-1" of the smart earphone 104 .

S102, the server 100 sends a patch 3 prompt message to the mobile phone 102, wherein the prompt message includes the terminal device that needs to be updated, that is, the smart earphone 104, and the version information of the "APP-1" of the device before and after the update is 4.0.0 Updated to 4.1.0.

S103, the mobile phone 102 detects that the user selects an update operation.

S104. The server 100 acquires a request from the user to agree to download the patch 3 and update "APP-1".

S105. The server 100 obtains the version information of "APP-1" of all terminal devices, and further determines the most relevant device in combination with Patch 3.

S106. The server 100 obtains difference data C according to difference between "APP-1" of the most relevant device and patch 3.

S107 , the server 100 sends the differential data C to the mobile phone 102 to the mobile phone 102 .

S108, the mobile phone 102 restores the patch 3 according to the most relevant module and the differential data C of "APP-1" in the most relevant device.

S109, the mobile phone 102 sends the “APP-1” patch 3 for updating the smart headset 104 to the smart headset 104 .

S110, the smart earphone 104 downloads and installs Patch 3, and performs a version update.

S111. The server 100 receives an instruction from the smart earphone 104 indicating that the update of "APP-1" is successful.

S112. The server 100 updates and saves the "APP-1" version information of the smart earphone 104.

S113. The server 100 sends an instruction indicating that the "APP-1" is successfully updated to the mobile phone 102.

S114, the mobile phone 102 displays a prompt message that the "APP-1" version of the smart earphone 104 has been successfully updated from 4.0.0 to 4.1.0.

As shown in FIG. 5 , the embodiment of the present application also provides a patch system 30 and a patch method implemented in the patch system. In the patch system shown in FIG. 5 , a terminal device with strong computing processing capability and relatively sufficient storage capability, such as the mobile phone 102, can be used as a "super terminal". "Hyper Terminal" can also utilize the relatively small differential data sent by the server 100 to restore a patch package suitable for the target device, and then "Hyper Terminal" sends the restored patch package to the target device, so that the server 100 also achieves the effect of not needing to directly transmit patch packages with a large amount of data to the target device, thereby reducing the amount of data transmission and reducing the burden on the network.

In some embodiments, the target device of the patch delivered by the server is not in the scenario of 1+8+N devices, but a single terminal device that can establish a connection and communicate with the mobile phone 102, so there is no most relevant module , and there is no most relevant device for the patch pack.

As exemplarily shown in FIG. 5 , the patch system 30 provided in the embodiment of the present application may include: a server 100 and terminal devices such as a mobile phone 102 and a smart earphone 104 . The mobile phone 102 and the smart earphone 104 can be in the same local area network by accessing the same Wi-Fi access point provided by the router 101 . The application program "APP-1" can be installed on terminal devices such as the mobile phone 102 and the smart earphone 104 . Wherein, the version of "APP-1" in the mobile phone 102 is 2.0.0, and the version of "APP-1" in the smart earphone 104 is 4.0.0.

In the patch system 30, taking upgrading the "APP-1" installed on the smart earphone 104 as an example, the patch method provided by the embodiment of the present application may include the following steps:

Step 2, the server 100 can use the "APP-1 4.0.0" of the smart earphone 104 and the patch 3 to generate three different differential data a, b and c, wherein it can be seen that the differential data a has the smallest data volume, and its size can be, for example, 80K , significantly smaller than the size of patch 3.

Step 3. The server 100 can send the differential data a to the mobile phone 102, and inform the mobile phone 102 of the target device (ie, the smart earphone 104) and the differential data.

Step 4, the mobile phone 102 can use the differential data a and the "APP-1 4.0.0" on the smart earphone 104 (specifically, it can be part of the data that has been differentiated), restore patch 3, and then, the mobile phone 102 can send the patch 3 to the smart earphone 104 104 (that is, the target device) sends the restored patch 3 .

Step 5, the smart earphone 104 can use the patch 3 of the mobile phone 102 to upgrade "APP-1", specifically, "APP-1" can be upgraded from the old version 4.0.0 to the new version 4.1.0.

It can be seen that since the patch system 30 provided by the embodiment of the present application has the role of "hyper terminal", the server 100 does not need to directly transmit patches with a large amount of data to each terminal device, but only needs to transmit patches to the "hyper terminal" Utilizes the smallest differential data compared to the amount of data generated by the patch pack and the application on the target device.

Further, the "Hyper Terminal" can use the differential data and the application program on the target device to restore the patch package, and transmit the patch package to the target device, so as to finally realize the application program upgrade on the target device. This patch technology significantly reduces the amount of data transmission between the server and each target device when the application program on each target device is upgraded.

In the above patch technology, how to generate the minimum difference data and how to use the difference data to restore the patch package will be described in detail below.

1. How to determine the minimum difference data

In the diagram of the method for determining the minimum differential data in step 2 shown in FIG. 6A and FIG. 6B , it includes patch 3, "APP-1" of the smart earphone 104, and the code structure of the differential data. It can be seen from Figure 6A that the "APP-1" of the smart headset 104 can be divided into three modules: FA1 interface code, Entrylegcy code and FA1 code according to its software architecture, and patch 3 can be divided into two modules: Entrylegcy code and FA1 code according to its software architecture. module,

What is special is that the Entrylegcy code module in patch 3 is not equivalent to only upgrading the Entrylegcy code module in the "APP-1" of the smart earphone 104, but the FA1 interface code and Entrylegcy code in the "APP-1" of the smart earphone 104. code Two modules are upgraded together. This will lead to uncertainty in the specific distribution of methods and variables on the two modules of FA1 interface code and Entrylegcy code in the "APP-1" of the smart earphone 104, so the minimum differential data is determined by three differential methods.

The determination of the minimum difference data diagram shown in Figure 6B and the three ways of difference shown in Figure 6C are the three ways of performing three ways between the software module on the patch 3 and the software module on the smart earphone 104 "APP-1". The difference is combined to form the difference data, including three ways of difference:

The first differential method is to differentiate the FA1 interface code module of the "APP-1" of the smart earphone 104 and the Entrylegcy code module in patch 3 to obtain a differential module 1, which includes variable 1-d, variable 2-b, and variable 2- e, variable 2-g and method 1-d, method 2-b, method 2-e, method 2-g, the FA1 code module of the "APP-1" of the smart earphone 104 and the FA1 code module in the patch 3 The difference is obtained by difference module 4, which includes variable 3-a, variable 3-d, method 3-a, method 3-d, and difference data a can be formed by difference module 1 and difference module 4.

The second differential method is to differentiate the Entrylegcy code module of "APP-1" of the smart earphone 104 and the Entrylegcy code module in patch 3 to obtain a differential module 2, which includes variable 1-a, variable 1-b, and variable 1-c , variable 1-d, variable 2-a, variable 2-c, variable 2-e, variable 2-g and method 1-a, method 1-b, method 1-c, method 1-d, method 2-a , method 2-c, method 2-e, method 2-g, the FA1 code module of the "APP-1" of the smart earphone 104 and the FA1 code module in the patch 3 are differentiated to obtain the difference module 4, the difference module 2 and the difference Module 4 can constitute differential data b.

The third differential method is to differentiate the FA1 interface code module and the Entrylegcy code module of the "APP-1" of the smart earphone 104 from the Entrylegcy code module in patch 3 to obtain a differential module 3, which includes variables 1-d and variable 2 -a, variable 2-c, variable 2-e, variable 2-g and method 1-d, method 2-a, method 2-c, method 2-e, method 2-g, the "APP The difference between the FA1 code module of -1" and the FA1 code module in patch 3 is obtained to obtain the difference module 4, and the difference module 3 and the difference module 4 can form the difference data c.

Then select the smallest differential data from the differential data a, b and c, and the differential data with the differential data a being the smallest can be obtained, so that when the server 100 transmits the differential data to the mobile phone 102, the amount of transmitted data is the smallest, and the transmission Highest efficiency, improving the efficiency of patches to fix urgent problems.

In the step 3 shown in Figure 6D on how to restore the patch method, the differential data a includes two modules, Entrylegcy code and FA1 code, where the Entrylegcy code module is composed of the Entrylegcy code module in patch 3 and the "APP-1" of the smart earphone 104. The difference between the FA1 interface code module in ", the FA1 code module is obtained by the difference between the FA1 code module in patch 3 and the FA1 code module in the "APP-1" of the smart earphone 104.

It can be seen that in the mobile phone 102, each module in the differential data a and the relevant modules in the "APP-1" of the smart earphone 104 that have performed differential operations (Figure 6D shows that "APP-1" in the smart earphone 104 "'s FA1 interface code module and FA1 code module) restore patch 3 based on the principle of removing common differences while reserving differences.

Its function allows users to automatically connect nearby Huawei mobile phones, batteries, tablets, speakers, computers, cameras and other smart devices equipped with Hongmeng OS system. , realize multi-device collaborative management, resource sharing, and form a collaborative work scene. The specific operation of the HyperTerminal is as follows: first turn on Bluetooth and WLAN on the mobile phone and log in the user account, then turn on Bluetooth and WLAN on other devices with Bluetooth and WLAN functions, and log in to the same account as the mobile phone.

Related devices for patch generation and effectiveness mainly involve servers and terminal devices. The server may include a patch shooting tool, a patch archive, a patch release, and the like. Among them, the patch shooting tool is a script running in the background of the server, which packs the patch files into a compressed file, and the overall layout of each file in the compressed file is unique to the patch package. The patch package archive is used to place the patch package to the specified archive address after the patch package tool generates the patch package, so that the subsequent server can obtain the patch package. The release of the patch package is used for the server to deliver the patch file to the terminal device. Terminal devices may include downloading of patch packages, patch engines, patch package upgrades, patch partitions, and the like. Wherein, the patch package download is used to receive the patch package delivered by the server. Patch package upgrade refers to the operation that the patch engine downloads, verifies, and installs the patch package after the user searches for the patch package on the mobile phone and confirms that the patch package is downloaded uniformly. The patch engine encapsulates various types of business logic, including the verification of patch files, enabling patches to take effect, and revoking abnormal patches. The patch partition is a space address on the hard disk of the terminal device, and the binary patch image in the patch package can be burned into this partition.
