In one embodiment, the computer program stored in the memory 220, when executed by the processor 280, causes the processor 280 to implement a method as described in embodiments herein.

The input unit 230 may be used to receive input numeric or character information and generate key signal inputs related to user settings and function control of the terminal device. Specifically, the input unit 230 may include a touch panel 232 and other input devices 234. The touch panel 232, also referred to as a touch screen, may collect touch operations of a user (e.g., operations of the user on or near the touch panel 232 using a finger, a stylus, or any other suitable object or accessory) thereon or nearby, and drive the corresponding connection device according to a preset program.

As shown in fig. 3, in an embodiment, a method for switching a SIM card is provided, which is applicable to the terminal device described above, and the method may include the following steps:

step 310, in the running process of the application, obtaining data transmission parameters of the first subscriber identity module SIM card.

The first SIM card may be an SIM card currently carrying data services in the terminal device, i.e. the above-mentioned SIM master card. When the application on the terminal device runs, data transmission parameters of the first SIM card in the running process of the application can be collected, the data transmission parameters can be used for representing the data transmission capability of the first SIM card in the running process of the application, and the data transmission capability of the first SIM card can also be understood as the data transmission capability of a network accessed by the terminal device through the first SIM card.

Optionally, when the terminal device receives a start request for starting an application, it may determine whether the application is using a cellular network (i.e., a mobile network), and if the application is using the cellular network, it may indicate that the application uses the cellular network and a server to perform data transmission during the operation process, and may obtain data transmission parameters of the first SIM card during the operation process of the application, where the cellular network may include, but is not limited to, a GSM network, a CDMA network, a 4G, 5G, WCDMA network, a TDMA (Time division multiple access) network, and the like.

In one embodiment, the usage right of the cellular network of the application running can be acquired, and if the application running is provided with the usage right of the cellular network, the application can be determined to use the cellular network. As another embodiment, an application service provided by the started application may also be acquired, and whether the started application uses the cellular network is determined according to the application service. For example, if the launched application provides a service that does not require networking, such as a calendar, a stand-alone game, image processing, etc., it may be determined that the launched application does not require use of the cellular network; if the started and running application provides a service needing networking, such as web browsing, chat communication and the like, it can be determined that the started and running application needs to use a cellular network.

Optionally, in the application running process, the terminal device may obtain the data transmission parameter of the first SIM card in real time, or may obtain the data transmission parameter of the first SIM card at regular intervals according to a time period, for example, the data transmission parameter may be obtained at intervals of 1 second, 2 seconds, 500 milliseconds, and the like, but is not limited thereto.

In some embodiments, the terminal device may use a Transmission Control Protocol (TCP) to perform data Transmission with the network device. The data transmission capability of the first SIM card may be evaluated using TCP integrated capabilities, which may include TCP handshake capabilities and TCP success rates. The data transmission parameters of the first SIM card in the application running process may include a TCP handshake success rate and a TCP retransmission rate when the application uses the first SIM card to perform data transmission in the running process. The TCP handshake success rate can refer to the success rate of sending TCP handshake by the terminal equipment, and data transmission can be normally carried out only after the TCP handshake is successful; the TCP retransmission rate may refer to the probability that a TCP packet retransmission occurs. The current data service transmission state can be reflected through data transmission parameters such as TCP handshake success rate, TCP retransmission rate and the like, and the data transmission capability of the first SIM card can be accurately reflected.

It should be noted that the data transmission parameters may include other parameters, such as signal strength, signal-to-noise ratio, and the like, in addition to the TCP handshake capability and the TCP success rate, which is not limited herein.

And step 320, when the data transmission parameters meet the switching conditions corresponding to the application, switching the first SIM card to the second SIM card.

The terminal equipment can be provided with a plurality of SIM cards, different SIM cards can respectively correspond to different mobile network operators, or the same mobile network operator but different corresponding network systems, and the like. For example, the terminal device may include at least a first SIM card and a second SIM card, where the first SIM card and the second SIM card may belong to different mobile network operation terminals respectively, and may also correspond to different network standards respectively, for example, the first SIM card supports a 3G network, the second SIM card supports a 4G network, and the like.

The switching condition corresponding to the running application can be obtained. In some embodiments, different applications may have different requirements for data transmission capability, for example, some applications may require high quality service data and require stronger data transmission capability (e.g., video applications, game applications, etc.), and some applications may require less quality service data (e.g., reading applications, chat applications, etc.), and require weaker data transmission capability. Therefore, the switching condition corresponding to the application can be set according to the requirement applied to the data transmission capability. When the acquired data transmission parameters meet the switching conditions corresponding to the application, it can be shown that the first SIM card currently carrying the service data is not enough to support the requirement of the application on the data transmission capability, and the SIM card needs to be switched.

As an embodiment, the switching condition may include that the TCP handshake success rate is less than a first threshold and/or the TCP retransmission rate is greater than a second threshold, and requirements for data transmission capabilities of different applications are different, and then the first threshold and the second threshold may be set according to a degree of the requirements for the data transmission capabilities of the applications. Further, the demand degree for the data transmission capacity can be in positive correlation with the first threshold, and the higher the demand degree is, the higher the requirement for the TCP handshake success rate can be; the level of demand for data transmission capacity may be inversely related to the second threshold, and the higher the level of demand, the lower the acceptable TCP retransmission rate may be.

In some embodiments, when the SIM card is switched, the terminal device may have a "network off" condition for a period of time, that is, during the process of switching from the first SIM card to the second SIM card, the terminal device may have a network-absent state since it just exits from the original network and does not use the new SIM card to access the new network. Therefore, the switching condition corresponding to the application can be set according to the sensitivity of the user to the SIM card switching in the running process of the application. For applications with higher sensitivity (e.g., mobile phone networking game applications, instant voice/video communication applications, etc.), a stricter switching condition may be set, and for applications with lower sensitivity (e.g., reading applications, web browsing applications, etc.), a more moderate switching condition may be set. For example, for an application in which the user has a high sensitivity to the SIM card switching, the corresponding switching condition may be that the TCP handshake success rate is smaller than the first threshold and the TCP retransmission rate is greater than the second threshold, and for an application in which the user has a low sensitivity to the SIM card switching, the corresponding switching condition may be that the TCP handshake success rate is smaller than the first threshold or the TCP retransmission rate is greater than the second threshold, but is not limited thereto. When the SIM card is switched, the experience of the user on the SIM card switching can be comprehensively considered, so that the influence of the SIM card switching on the use of the user is reduced.

When the data transmission parameters meet the switching conditions corresponding to the currently running application, it can be shown that the first SIM card currently carrying the data service cannot meet the requirements of the application on the quality of service data, the first SIM card can be switched to the second SIM card, and the second SIM card is used as a data master card and is accessed to a network corresponding to the second SIM card for communication, so that the data transmission capability of the terminal device can be improved. Optionally, after switching to the second SIM card for network communication, the terminal device may continue to acquire the data transmission parameter of the second SIM card, and may determine the data transmission capability of the second SIM card according to the data transmission parameter of the second SIM card. If the data transmission capability of the second SIM card is lower than that of the first SIM card, the second SIM card can be switched back to the first SIM card again, or the second SIM card is continuously switched to another SIM card under the condition that other SIM cards exist, so that the data service quality in the application running process is guaranteed.

In the embodiment of the application, in the running process of the application, the data transmission parameter of the first SIM card currently carrying the data service is acquired, the data transmission parameter can be used for representing the data transmission capability of the first SIM card, when the data transmission parameter meets the switching condition corresponding to the application, the first SIM card is switched to the second SIM card, the data transmission capability of the SIM card currently carrying the data service can be quantified through the data transmission parameter, whether the SIM card is switched or not is judged by combining the running application, the automatic switching of the SIM card can be more accurately realized, and the data transmission capability of the terminal is improved.

As shown in fig. 4, in an embodiment, another method for switching a SIM card is provided, which is applicable to the terminal device described above, and the method may include the following steps:

step 402, in the running process of the application, acquiring data transmission parameters of the first subscriber identity module SIM card.

The description of step 402 can refer to the related description of step 310 in the above embodiments, and is not repeated herein.

In some embodiments, when the application is started, a network standard corresponding to a data service that needs to be executed in an application running process can be acquired, whether a network standard of a first SIM card currently carrying the data service is matched with a network standard corresponding to the data service that needs to be executed by the application is judged, if not, the first SIM card can be directly switched to a second SIM card, and the network standard of the second SIM card can be matched with the network standard corresponding to the data service that needs to be executed by the application. For example, the started application is a game application, the network system corresponding to the data service that the game application needs to execute may be 4G, 5G, and the like, and if the network system of the SIM card currently serving as the data master card is 3G, the SIM card may be switched to the SIM card supporting 4G or 5G and accessed to the network of 4G or 5G for data transmission.

After the SIM card with the network system matched with the network system corresponding to the data service required to be executed by the application is accessed into the corresponding network, the normal operation of the application can be ensured, the data transmission parameters of the application are acquired by the SIM card currently bearing the service data in the operation process of the application, and whether the data transmission is abnormal or not is judged according to the acquired data transmission parameters.

And step 404, when the data transmission is determined to be abnormal according to the data transmission parameters, determining the application type of the application.

In some embodiments, the data transmission abnormality may include at least one of a TCP handshake success rate being less than a first threshold and a TCP retransmission rate being greater than a second threshold. Alternatively, the first threshold and the second threshold may be fixed values, for example, the first threshold is 60%, the second threshold is 50%, and the like, and the first threshold and the second threshold may also be dynamically adjusted, for example, the setting may be performed according to the requirement of the currently running application on the data transmission capability, and the like, and is not limited herein.

Fig. 5 is a diagram illustrating TCP establishing a connection in one embodiment. As shown in fig. 5, the terminal device 10 may initiate a TCP connection request to the network device 20, and the terminal device 10 may transmit a SYN (synchronization Sequence number) message to the network device 20. After receiving the SYN message sent by the terminal device 10, the network device 20 may return an acknowledgement message of SYN + ACK (acknowledgement character) to the terminal device 10. After receiving the acknowledgement message of SYN + ACK sent by network device 20, terminal device 10 may send an ACK acknowledgement message to network device 20, and through three-way handshake, TCP connection is successfully established between terminal device 10 and network device 20, and terminal device 10 and network device 20 may perform data transmission.

In the application running process, when different service modules need to transmit service data to the network device, TCP connection can be established with the network device 20. The total TCP handshake initiation times applied in the current operation process (namely from the start operation to the current time) can be obtained at regular intervals, the TCP handshake success times applied in the current operation process can be obtained, the proportion of the TCP handshake success times to the total TCP handshake initiation times can be calculated, and the TCP handshake success rate can be obtained. The TCP handshake success refers to completing three-way handshake and establishing TCP connection, and the TCP handshake failure refers to failure of establishing TCP connection caused by any failure in the three-way handshake (for example, the terminal device does not receive an acknowledgement message of SYN + ACK returned by the network device, or the network device does not receive a SYN acknowledgement message sent by the terminal device, etc.).

After the terminal device establishes TCP connection with the network device, the terminal device may send a TCP data packet to the network device for data transmission, and if a response data packet returned by the network device is not received within a certain time period, the terminal device may resend the TCP data packet to the network device, that is, perform TCP data packet retransmission. The number of times of TCP data packet retransmission of the application in the current operation process (namely from starting operation to the current time) can be obtained at regular intervals, the total number of times of TCP data packet transmission of the application in the current operation process is obtained, the ratio of the TCP data packet retransmission number to the TCP data packet transmission number can be calculated, and the TCP retransmission rate is obtained.

In some embodiments, the terminal device may obtain the data transmission parameter of the first SIM card in the running process of the foreground application. When the obtained TCP handshake success rate is less than a first threshold and/or the TCP retransmission rate is greater than a second threshold, it may be determined that data transmission of the currently running application in the foreground is abnormal in the running process, an application type to which the currently running application in the foreground belongs may be obtained, and it may be determined whether a data transmission parameter of the currently data service-bearing first SIM card in the running process of the currently running application in the foreground satisfies a switching condition corresponding to the application type, and if so, the first SIM card may be switched to the second SIM card.

And step 406, when the data transmission parameter meets a switching condition corresponding to the application type, switching the first SIM card to the second SIM card.

In some embodiments, applications may be classified according to the amount of data that the applications need to transmit, the way they interact with the user, and so on, and the types of applications to which the applications belong may include, but are not limited to, the following types:

the type I and the application type are real-time interaction type applications. The real-time interactive application can comprise game applications and social media applications (such as short video applications and news applications), data transmission needs to be carried out in real time in the application running process, a user can possibly interact with the application in real time, and the user has high sensitivity on SIM card switching. The switching condition corresponding to the real-time interactive application may be a relatively strict switching condition.

Optionally, the data transmission parameter further includes Round-Trip Time (RTT), where RTT refers to Time for transmitting a data packet from the terminal device to the network device, and a longer RTT may indicate a slower data transmission speed and a poorer network quality. The switching condition corresponding to the real-time interactive application may include: the TCP handshake success rate is smaller than a first threshold, the TCP retransmission rate is larger than a second threshold, and the RTT is larger than a time threshold. When the terminal device determines that the TCP handshake success rate is smaller than the first threshold and the TCP retransmission rate is greater than the second threshold, it may further determine whether the RTT of the TCP data packet transmitted by the application is greater than a time threshold, if the RTT is greater than the time threshold, the first SIM card may be switched to the second SIM card, and if the RTT is not greater than the time threshold, it may be said that the current data transmission is within a tolerable range, the switching may not be performed. The time threshold may be set according to actual requirements or empirical values, such as 250 ms, 230 ms, 276 ms, and the like. The SIM card is switched when necessary, so that the adverse effect of the SIM card switching on the use process of the application of the user can be reduced.

Further, when the acquired data transmission parameters meet the switching conditions corresponding to the real-time interactive application, the interactive operation performed by the user can be detected, and if the interactive operation is not detected within the first time period, the first SIM card can be switched to the second SIM card. The first time period may also be set according to actual requirements or empirical values, such as 5 seconds, 10 seconds, 13 seconds, and the like. The first time length can also be set according to the network disconnection time length in the SIM card switching process, and the longer the network disconnection time length is, the larger the influence on the user in the application and use process is, the longer the set first time length can be; the shorter the network disconnection time is, the smaller the influence on the user in the application use process is, and the shorter the set first time can be. When the user does not perform interactive operation, the attention of the user to the application is slightly reduced, and the SIM card switching is performed at the moment, so that the adverse effect of the SIM card switching on the user in the application using process can be further reduced.

And the type II, the application type is a resource preloading type application. The resource preloading application can comprise a video application, an audio application and the like, and a part of multimedia resources can be preloaded in the running process of the application, so that the user is prevented from being blocked when the multimedia data is played and displayed. Because the application will pre-load a part of resources, the sensitivity of the user to the SIM card switching is slightly low, but because the resource pre-loading application has a large demand for network resources, if the data transmission capability of the first SIM card currently carrying data services is too poor, the use of the resource pre-loading application will be affected.

Optionally, the switching condition corresponding to the preloaded class application may include: the TCP handshake success rate is less than a first threshold, and the TCP retransmission rate is greater than a second threshold. The pre-loading application does not judge whether the RTT is larger than a time threshold value, but switches the first SIM card to the second SIM card when detecting that the TCP handshake success rate is smaller than a first threshold value and the TCP retransmission rate is larger than a second threshold value, so that the data transmission capacity of the terminal equipment when the pre-loading application is used can be improved, the set switching condition is neither too strict nor too moderate, and the influence of SIM card switching on the application use process can be reduced while the data transmission capacity is ensured.

Further, when the acquired data transmission parameters satisfy the switching conditions corresponding to the resource preloading type application, the data volume of the currently preloaded resource can be acquired. If the current preloaded resource is larger than the resource threshold value, which indicates that the data volume of the preloaded resource is large enough, and the use of the user is not affected when the SIM card is switched, the first SIM card can be switched to the second SIM card. The resource threshold may also be set according to actual requirements or empirical values, such as 2MB (megabyte), 0.5MB, 1.7MB, and the like. The resource threshold value can also be set according to the network disconnection time length in the SIM card switching process, and the longer the network disconnection time length is, the larger the set resource threshold value can be; the shorter the network disconnection time is, the smaller the set resource threshold value can be. The adverse effect of SIM card switching on the use process of the application for the user can be further reduced.

And the type III, the application type is a page browsing application. The page browsing application may include a browser application, a reading application, and the like, and the page browsing application has a smaller demand for network resources, and the user has a low sensitivity to SIM card switching during the application use process, so the switching condition corresponding to the page browsing application may be a relatively mild switching condition.

Optionally, the switching condition corresponding to the page browsing application may be that the TCP handshake success rate is less than a first threshold, or that the TCP retransmission rate is greater than a second threshold. And when the terminal equipment detects that the TCP handshake success rate is smaller than a first threshold or detects that the TCP retransmission rate is larger than a second threshold, the first SIM card can be switched to the second SIM card.

It should be understood that the application types to which the application belongs are not limited to the above-mentioned types, each application type may set different switching conditions, multiple application types may also set the same switching conditions, and the switching conditions are not limited to the above-mentioned conditions, and the application types and the switching conditions are not limited in the embodiments of the present application.

In some embodiments, the applications may include a foreground running application and/or a background running application, wherein the foreground running application may refer to an application that can see a running interface on a screen of the terminal device, and the background running application may refer to an application that does not see a running interface. For an application running on a terminal device, there may be, but are not limited to, the following:

1. there is only a foreground application running. If the current terminal equipment has the application running in the foreground, the data transmission parameters of the first SIM card aiming at the foreground application can be obtained in the process that the foreground application is running, and whether the SIM card is switched or not is judged according to the method described in the steps 402-406.

2. There is only a background application running. If the applications in the current terminal device are all running in the background, the data transmission parameters of the first SIM card for each background application can be acquired, and different applications may have a requirement for data transmission with the network device during running, so that the data transmission parameters can be acquired according to TCP data packets sent to the network device during the running process of each background application. The first SIM card can be analyzed for data transmission parameters of each background application, and whether SIM card switching is needed or not is judged.

Optionally, the TCP handshake success rate and the TCP retransmission rate of each background application may be obtained, and whether data transmission abnormality occurs in each background application is determined according to the TCP handshake success rate and the TCP retransmission rate. If the proportion of the background application with abnormal data transmission is larger than a proportion threshold value, the abnormal data transmission is a common phenomenon, and the quality of the network accessed through the first SIM card is poor, the first SIM card can be switched to the second SIM card.

3. There is foreground application and background application running at the same time. Optionally, only in the process that the foreground application is in foreground operation, the first SIM card may determine whether to perform SIM card switching according to the method described in the above steps 402 to 406, with respect to the data transmission parameter of the foreground application.

Optionally, the data transmission parameters of the first SIM card for the foreground application may also be obtained in the running process of the foreground application, and meanwhile, the data transmission parameters of the first SIM card for each background application may be obtained in the running process of each background application. The data transmission parameters of foreground application and background application can be analyzed at the same time, and whether SIM card switching is needed or not is judged. The TCP handshake success rate and the TCP retransmission rate of foreground application can be obtained, and whether data transmission abnormity occurs in the foreground application or not is judged according to the TCP handshake success rate and the TCP retransmission rate.

If the foreground application has data transmission abnormity, whether the data transmission abnormity also occurs in each background application can be judged according to the TCP handshake success rate and the TCP retransmission rate of each background application. When data transmission of background application is normal, network resources occupied by the background application with normal data transmission can be acquired, if the occupied network resources are larger than a preset resource threshold value, the background application can occupy too many network resources, data transmission of foreground application is influenced, and the background application can be suspended or closed. Alternatively, the resource threshold may be set according to actual requirements, e.g., 500kbps (kilobits), 687kbps, etc.

Optionally, if data transmission abnormality occurs in the foreground application, meanwhile, the proportion of the data transmission abnormality occurring in the background application is greater than the proportion threshold, and the network resource occupied by the background application with normal data transmission is not greater than the resource threshold, it can be said that the data transmission abnormality is a general phenomenon, and the quality of the network accessed through the first SIM card is poor at present, the first SIM card can be switched to the second SIM card.

In the embodiment of the application, in the running process of the application, if the data transmission is determined to be abnormal according to the acquired data transmission parameter of the first SIM card, the application type to which the application belongs is determined, and when the data transmission parameter meets the switching condition corresponding to the application type, the first SIM card is switched to the second SIM card, and different switching conditions can be set for different application types, so that the influence of SIM card switching on the application using process can be reduced while the data transmission capability in the running process of the application is improved, and the automatic switching of the SIM cards can be more accurately realized.
