Detailed ways

In the application switching control method, device, and service acceptance terminal of the embodiments of the present invention, when switching is required, the application corresponding to the business that is no longer needed at present is directly switched to run in the background, and its sign-in state is maintained. When you come to the foreground to perform business, because it is already running in the background and is in the sign-in state, there is no need to restart or sign-in, which improves the speed and efficiency of application switching.

Before describing the method in the embodiment of the present invention in detail, first briefly describe the structure of the service acceptance terminal in the embodiment of the present invention, so as to better understand the embodiment of the present invention.

As shown in Figure 1, the service acceptance terminal of the embodiment of the present invention is a 4-layer structure, including:

The hardware platform is exactly the same as the existing hardware platform and will not be described in detail here;

Software platform, including operating system, hardware platform drivers, etc.;

API (Application Programming Interface, application programming interface) is some pre-defined functions, which can provide the interface of the application layer to access the software platform, and make corresponding changes according to the specific application.

Application layer. In a specific embodiment of the present invention, the application layer includes at least two applications, which are uniformly allocated with corresponding IDs.

For example, for financial acceptance terminals, these applications can be UnionPay card swiping applications, various prepaid card acceptance programs (Zihexin, Bailian Card, Shande Card...), etc. For different application environments, these applications are different and will not be listed here.

Because each application has its own different library functions, but as far as financial acceptance is concerned, some library functions can be shared by multiple applications, such as the library of EMV (VISA, MASTERCARD, financial IC card standards formulated by EUROPAY International Card Organization) Functions, library functions of PBOC (financial IC card standard formulated by the People's Bank of China), etc.

In a specific embodiment of the present invention, the functions shared by multiple applications in the at least two applications are stored in the software platform running on the service acceptance terminal, and are called by the applications to execute corresponding services. In this way, the application of the upper layer can simplify the development, and only need to consider the business logic without considering the function interface.

Of course, each application can use its own library functions without sharing them, and this does not affect the implementation of the embodiments of the present invention.

The application switching control method of the embodiment of the present invention is used in a service acceptance terminal, and at least two applications are installed in the service acceptance terminal, and each application corresponds to a service that can be processed respectively. The application switching control method includes a service switching Process, as shown in Figure 2, the service switching process includes:

Step 201, during the operation of the service acceptance terminal, determine the first service currently to be processed;

Step 202, determining a first application corresponding to the first service among the at least two applications;

Step 203, calling the first application through the first main application currently running in the foreground, so that the first application is running in the foreground to execute the first service;

Step 204, control the first main application to switch to run in the background, and maintain the sign-in state of the first main application.

In a specific embodiment of the present invention, after determining the business that currently needs to be processed, the application corresponding to the business will be determined, and the first application will be called to run in the foreground to execute the first business; The main application (currently running in the foreground) that is not needed for the processed business is switched to running in the background, and the sign-in state of the first main application is maintained.

Since the first main application has been running in the background without exiting, and is also in the sign-in state, when a business corresponding to the first main application needs to be processed in a later period of time, it is only necessary to switch the first main application to The business can be processed by running in the foreground, and there is no need to restart the first main application, nor to log in again, so the switching speed and efficiency are greatly improved.

In the specific embodiment of the present invention, there is the concept of the main application, the main application is not a fixed application, but whoever is in the foreground is the main application, and the main application also has the right to schedule other applications, which will be discussed later Describe in detail.

Of course, when the application processes the corresponding business, it is necessary to complete the sign-in of the application on the corresponding service platform.

Therefore, in a specific embodiment of the present invention, a sign-in processing process is further included to complete the sign-in of each of the at least two applications on the respective corresponding service platforms.

Application sign-in in specific embodiments of the present invention can be implemented in various ways, which are described as follows.

<Sign-in processing method 1>

In the first way, the sign-in of all applications is completed through the default application.

In this way, the check-in process is executed before the service switching process, including:

After the service acceptance terminal is started, start the default application among the at least two applications, so that the default application completes sign-in as the second main application and runs in the foreground;

The sign-in of other applications in the at least two applications except the default application on their respective corresponding service platforms is completed through the second main application.

Examples are as follows.

As shown in FIG. 1 , it is assumed that a total of n applications 1, 2, 3...n are installed in the service acceptance terminal. Assume application #1 is the default application.

In the first way, after the service acceptance terminal is started, it will first start the application #1, and after the application #1 is started, it will sign in to the corresponding service platform.

At the same time, application #1 will replace applications #2, 3, . . . , n to sign in to the corresponding service platform.

Assume that after a period of time, the service that needs to be processed corresponds to application #3. At this time, it is only necessary to start application #3, and application #3 no longer needs to sign in to the corresponding service platform to perform service processing.

When the application #3 needs to be used for the second time, it can be directly switched from the background to the foreground for business processing, no need to restart or sign in.

Of course, registering with the corresponding service platform by application #1 instead of other applications requires pre-negotiation between the application and the service platform. How to negotiate is not in the scope of the embodiments of the present invention, and will not be described in detail here.

<Sign-in processing method 2>

In the second way, the sign-in of the application is completed by each application itself, but it is completed uniformly after the business acceptance terminal is started.

In this way, the check-in process is executed before the service switching process, including:

After the service acceptance terminal is started, start the default application among the at least two applications, so that the default application completes sign-in as the second main application and runs in the foreground;

Control other applications in the at least two applications except the default application to be running in the background, and complete sign-in.

Examples are as follows.

As shown in FIG. 1 and FIG. 3 , it is assumed that a total of n applications of applications #1, 2, 3...n are installed in the service acceptance terminal. Assume application #1 is the default application.

In mode 2, after the service acceptance terminal is started, application #1 (the main application) will be started first, and after application #1 is started, it will sign in to the corresponding service platform.

Afterwards, the applications #2, 3, ..., n will be controlled to enter the background running state, and the applications will complete their respective sign-ins and run in the background all the time.

After the above process, the accepting terminal will be in the use state of the main application, that is, the application #1 is in the foreground, and other applications are executed in the background.

Assume that after a period of time, the business that needs to be processed corresponds to application #3. At this time, there will be no request to switch to application #3. At this time, application #1 will call application #3 through the ID of application #3, and switch itself from the foreground Run in the background, but keep your own sign-in status;

After the application #3 is called, it switches from the background to the foreground, enters the interface of the application #3, connects with the service platform corresponding to the application #3, and performs business processing without restarting or signing in.

<Sign-in processing method 3>

In mode 3, the default application completes the sign-in and becomes the main application after the business acceptance terminal is started, while other applications will start and complete the sign-in when needed.

In mode 3, the sign-in process includes:

After the service acceptance terminal is started, start the default application among the at least two applications, so that the default application completes sign-in as the second main application and runs in the foreground;

Invoking the first application through the first main application currently running in the foreground, so that the first application is running in the foreground to execute the first service specifically includes:

When the first application is invoked for the first time, start the first application through the first main application, so that the first application completes sign-in and runs in the foreground to execute the first service; otherwise, through the The first main application invokes the first application running in the background, and switches the first application currently running in the background to run in the foreground, so as to execute the first service.

Examples are as follows.

As shown in FIG. 1 , it is assumed that a total of n applications of applications #1, 2, 3...n are installed in the service acceptance terminal. Assume application #1 is the default application.

Then in mode 2, after the service acceptance terminal is started, at time t1, application #1 will be started, and after application #1 is started, it will sign in to the corresponding service platform.

Assume that at time t2, the business that needs to be processed corresponds to application #3. At this time, application #3 will be called and started by application #1, and it will complete the sign-in and run in the foreground by itself, and then execute the corresponding business;

Assume that at time tn, the business that needs to be processed corresponds to application #n. At this time, application #n will be called by application #n-1 to start, and it will complete the sign-in and run in the foreground by itself, and then execute the corresponding business;

So far, all applications have been started, and one of the applications is running in the foreground as the main application, while the other n-1 applications are running in the background and are in the check-in state.

Thereafter, at time tm, it is assumed that the business to be processed corresponds to application #3, and at this time application #3 will be called by application #1 to switch to the foreground to become the main application, and then execute the corresponding business.

The above three sign-in methods are merely examples, and other sign-in methods can also be applied to the embodiment of the present invention, and will not be described here one by one.

But regardless of the sign-in method, after the app is started and signed in, the app will switch to the background for execution when not in use, and one of the apps can be kept as the main app.

However, the applications executed in the background only need to be switched to the foreground for execution when needed, which improves the switching speed and efficiency.

In the existing multi-application business acceptance terminal, when an application is upgraded, the entire program needs to be downloaded and updated, resulting in a large amount of downloaded data and low update efficiency.

However, in a specific embodiment of the present invention, when an application is updated, the upgrade program of the corresponding application is directly downloaded, and then the update program is executed to complete the update of the application.

The above application update process includes:

When the second application of the at least two applications needs to be upgraded, interacting with the accepting terminal application platform to download an upgrade program corresponding to the second application;

Executing the upgrade program to upgrade the second application.

The description is as follows in conjunction with the application scenario shown in FIG. 4 .

As shown in FIG. 4 , multiple acceptance terminals are connected to an acceptance terminal application management platform, and acceptance terminals are connected to different service platforms according to different installed applications.

When an application in one of the acceptance terminals needs to be upgraded, the acceptance terminal interacts with the acceptance terminal application platform to download an upgrade program corresponding to the second application; and then executes the upgrade program to upgrade the second application. Compared with the prior art, the acceptance terminal only needs to download the programs corresponding to the applications that need to be updated, instead of downloading all the applications, which reduces the amount of downloaded data and improves the update efficiency.

The above update process is described in detail below.

As shown in Figure 5, the detailed download process includes:

First, the acceptance terminal will send a link establishment request message to the acceptance terminal application platform, requesting to establish a link with the acceptance terminal application platform.

After receiving the link establishment request message, the acceptance terminal application platform interacts with the acceptance terminal to establish a link, and returns a link establishment message to the acceptance terminal.

After the link is established, the acceptance terminal and the acceptance terminal management platform will complete the download of the upgrade program one by one, and the number of interactions depends on the size of the upgrade program.

After several interactive downloads are completed, the accepting terminal will notify the accepting terminal management platform that the download is complete, request to end the download, the accepting terminal management platform will respond to the message, and finally the two interact to remove the established link.

The embodiment of the present invention also provides an application switching control device, which is used in a service acceptance terminal, where at least two applications are installed in the service acceptance terminal, and each application corresponds to a service that can be processed respectively, and the application switching control The device includes a service switching module, and the service switching module is shown in Figure 6, including:
