As shown in fig. 3, in one embodiment, a method for switching a SIM card is provided and may be applied to the terminal device described above, where the method may include the following steps:
step 310, acquiring data transmission parameters of the first subscriber identity module SIM card during the running process of the application.
The first SIM card may be a SIM card currently carrying a data service in the terminal device, i.e. the SIM master card described above. When an application on the terminal equipment is running, 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 capacity of the first SIM card in the running process of the application, and the data transmission capacity of the first SIM card can be understood as the data transmission capacity of a network accessed by the terminal equipment through the first SIM card.
Optionally, when the terminal device receives a start request for starting the application, it may determine whether the application started uses a cellular network (i.e. a mobile network), and if the application started uses the cellular network, it may indicate that the application uses the cellular network and a server to perform data transmission during operation, and may acquire a data transmission parameter of the first SIM card during operation of the application, where the cellular network may include, but is not limited to, a GSM network, a CDMA network, a 4G, a 5G, WCDMA network, a TDMA (Time division multiple access ) network, and so on.
As one embodiment, the use authority of the cellular network of the application started and operated may be acquired, and if the application started and operated has the use authority of using the cellular network, it may be determined that the application uses the cellular network. As another embodiment, an application service provided by the application started to run may be obtained, and whether the application started to run uses the cellular network may be determined according to the application service. For example, if the application started to run provides a service such as a calendar, a stand-alone game, image processing, etc. that does not need to be networked, it may be determined that the application started to run does not need to use a cellular network; if the application started to run provides the service requiring networking, such as web browsing, chat communication, etc., then it can be determined that the application started to run needs to use the cellular network.
Optionally, during the application running process, the terminal device may acquire the data transmission parameters of the first SIM card in real time, or may acquire the data transmission parameters of the first SIM card at regular intervals according to a time period, for example, may acquire the data transmission parameters of the first SIM card at intervals of 1 second, 2 seconds, 500 milliseconds, or the like, but is not limited thereto.
In some embodiments, the terminal device may employ TCP (Transmission Control Protocol ) for data transmission with the network device. The data transmission capability of the first SIM card may be evaluated using a TCP integration capability, which may include a TCP handshake capability and a TCP success rate. The data transmission parameters of the first SIM card in the running process of the application can comprise TCP handshake success rate, TCP retransmission rate and the like when the application uses the first SIM card for data transmission in the running process. The success rate of TCP handshake can refer to the success rate of the terminal equipment to send TCP handshake, and data transmission can be normally performed only after the TCP handshake is successful; the TCP retransmission rate may refer to the probability that a TCP packet retransmission will occur. The current data service transmission state can be reflected through the data transmission parameters such as TCP handshake success rate, TCP retransmission rate and the like, and the data transmission capacity of the first SIM card can be accurately reflected.
It should be noted that, the data transmission parameters may include, in addition to the TCP handshake capability and the TCP success rate, other parameters, such as signal strength, signal-to-noise ratio, and the like, which are not limited herein.
Step 320, when the data transmission parameter satisfies the switching condition corresponding to the application, the first SIM card is switched to the second SIM card.
The terminal equipment can be provided with a plurality of SIM cards, and different SIM cards can respectively correspond to different mobile network operators, or can be the same mobile network operators but different corresponding network systems and the like. 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 ends, or may respectively correspond to different network formats, for example, the first SIM card supports a 3G network, the second SIM card supports a 4G network, and so on.
The switching condition corresponding to the running application may be obtained. In some embodiments, the requirements of different applications for data transmission capability may be different, for example, some applications require high quality of service data, and then require stronger data transmission capability (e.g., video applications, game applications, etc.), and some applications require less quality of service data (e.g., reading applications, chat applications, etc.), and then require weaker data transmission capability. Accordingly, 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 stated that the first SIM card carrying the service data currently is insufficient to support the requirement of the application on the data transmission capability, and the SIM card needs to be switched.
As an implementation manner, the switching condition may include that the success rate of the TCP handshake is smaller than a first threshold and/or the retransmission rate of the TCP is larger than a second threshold, and the first threshold and the second threshold may be set according to the degree of the requirement of the application for the data transmission capability if the requirements of different applications for the data transmission capability are different. Further, the degree of demand for data transmission capability may be in positive correlation with the first threshold, and the higher the degree of demand, the higher the requirement for TCP handshake success rate may be; the degree of demand for data transmission capacity may be inversely related to the second threshold, the higher the degree of demand, the lower the acceptable TCP retransmission rate.
In some embodiments, the terminal device may have a network failure state because the terminal device just exits the network to which the terminal device has been connected and does not use a new SIM card to access a new network when the terminal device performs the SIM card switching, i.e., the terminal device may have a network failure state in the process of switching from the first SIM card to the second SIM card. Therefore, the corresponding switching condition of the application can be set according to the sensitivity degree of the user to the switching of the SIM card in the running process of the application. For applications with higher sensitivity (such as mobile phone networking game applications, instant voice/video communication applications, etc.), more stringent switching conditions can be set, and for applications with lower sensitivity (such as reading applications, web browsing applications, etc.), more moderate switching conditions can be set. For example, the application with higher sensitivity of the user to SIM card switching may be an application with lower sensitivity of the user to SIM card switching, where the corresponding switching condition may be, but is not limited to, the TCP handshake success rate is less than the first threshold and the TCP retransmission rate is greater than the second threshold. And when the SIM card is switched, the user experience of 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 stated that the first SIM card carrying the data service can not meet the requirements of the application on the quality of service data, the first SIM card can be switched to the second SIM card, the second SIM card is used as a data main card and is accessed into a network corresponding to the second SIM card for communication, and the data transmission capability of the terminal equipment can be improved. Optionally, after switching to the second SIM card to perform network communication, the terminal device may continuously 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 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 ensured.
In the embodiment of the application, in the running process of the application, the data transmission parameter of the first SIM card carrying the data service at present is obtained, the data transmission parameter can be used for representing the data transmission capacity 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 capacity of the SIM card carrying the data service at present can be quantified through the data transmission parameter, and whether the SIM card is switched or not is judged by combining the running application, so that the automatic switching of the SIM card can be realized more accurately, and the data transmission capacity of the terminal is improved.
As shown in fig. 4, in one embodiment, another method for switching SIM cards is provided and may be applied to the terminal device described above, where the method may include the following steps:
step 402, acquiring data transmission parameters of a first Subscriber Identity Module (SIM) card in the running process of an application.
The description of step 402 may refer to the related description of step 310 in the above embodiment, and will not be repeated here.
In some embodiments, when an application is started, a network system corresponding to a data service to be executed in an application running process may be obtained, and whether the network system of a first SIM card currently carrying the data service matches the network system corresponding to the data service to be executed by the application may be determined, if not, the first SIM card may be directly switched to a second SIM card, where the network system of the second SIM card may match the network system corresponding to the data service to be executed by the application. For example, the application started is a game application, the network system corresponding to the data service required to be executed by the game application may be 4G, 5G, etc., if the network system of the SIM card currently used as the data master card is 3G, the network system is not matched, the network system may be switched to the SIM card supporting 4G or 5G, and the network system is accessed to the network of 4G or 5G for data transmission.
After the SIM card which adopts the network system and can be matched with the network system corresponding to the data service required to be executed by the application is accessed to the corresponding network, the normal operation of the application can be ensured, the data transmission parameters of the current SIM card carrying the service data aiming at the application in the operation process of the application are acquired, 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 to which the application belongs.
In some embodiments, the occurrence of the anomaly in the data transmission 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 value and the second threshold value may be fixed, for example, the first threshold value is 60%, the second threshold value is 50%, and the like, and the first threshold value and the second threshold value may be dynamically adjusted, for example, the first threshold value and the second threshold value may be set according to the requirement of the data transmission capability of the currently running application, and the like, which is not limited herein.
Fig. 5 is a schematic diagram of TCP setup connection in one embodiment. As shown in fig. 5, terminal device 10 may initiate a TCP connection request to network device 20, and terminal device 10 may send a SYN (Synchronize Sequence Numbers, synchronization sequence number) message to network device 20. The network device 20, upon receiving the SYN message sent by the terminal device 10, may return an acknowledgement message of syn+ack (Acknowledge character, acknowledgement character) to the terminal device 10. After receiving the acknowledgement message of syn+ack sent by the network device 20, the terminal device 10 may send an ACK acknowledgement message to the network device 20, and through three handshakes, the terminal device 10 and the network device 20 successfully establish a TCP connection, and the terminal device 10 and the 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, a TCP connection can be established with the network device 20. The total number of times of TCP initiation handshake in the current operation process (namely from starting operation to current time) of the application can be obtained at regular intervals, the successful number of times of TCP handshake in the current operation process of the application is obtained, and the ratio of the successful number of times of TCP handshake to the total number of times of TCP initiation handshake can be calculated to obtain the success rate of TCP handshake. The successful TCP handshake refers to that the three-way handshake is completed and the TCP connection is established, and the failure of the TCP handshake refers to that any failure in the three-way handshake (for example, the terminal device does not receive the acknowledgement application message of syn+ack returned by the network device, or the network device does not receive the SYN acknowledgement message sent by the terminal device, etc.) results in failure to establish the TCP connection.
After the terminal device establishes TCP connection with the network device, the terminal device can send TCP data packets to the network device for data transmission, and if the response data packets returned by the network device are not received within a certain duration range, the TCP data packets can be resent to the network device, namely, the TCP data packet retransmission is carried out. The number of times of TCP data packet retransmission of the application in the running process (namely from starting running to the current moment) can be obtained at regular intervals, the total number of times of TCP data packet transmission of the application in the running process can be obtained, and the ratio of the number of times of TCP data packet retransmission to the total number of times of TCP data packet transmission can be calculated to obtain the TCP retransmission rate.
In some embodiments, the terminal device may obtain the data transmission parameters of the first SIM card during the running of the foreground application. When the acquired TCP handshake success rate is smaller than a first threshold value and/or the TCP retransmission rate is larger than a second threshold value, determining that data transmission abnormality occurs in the running process of the application running in the foreground at present, acquiring the application type of the application running in the foreground at present, judging whether the data transmission parameters of the first SIM card carrying the data service at present in the running process of the application running in the foreground meet the switching conditions corresponding to the application type, and if so, switching the first SIM card to the second SIM card.
And step 406, switching the first SIM card to the second SIM card when the data transmission parameter meets the switching condition corresponding to the application type.
In some embodiments, applications may be categorized according to the amount of data that the application needs to transfer, the manner in which the application interacts with the user, etc., and exemplary types of applications to which the application belongs may include, but are not limited to, the following:
the type one and the application type are real-time interactive applications. The real-time interaction applications can comprise game applications and social media applications (such as short video applications and news applications), data transmission is required to be carried out in real time in the application running process, a user can interact with the applications in real time, and the sensitivity of the user to SIM card switching is high. The switching condition corresponding to the real-time interactive application may be a stricter switching condition.
Optionally, the data transmission parameters further include Round-Trip Time (RTT), where RTT refers to a Time for a data packet to be transmitted from the terminal device to the network device, and the longer the RTT, the slower the data transmission speed, and the network quality is worse. The switching conditions corresponding to the real-time interactive 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, and the RTT is greater than a time threshold. When the terminal equipment judges 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, the terminal equipment can further judge whether the RTT of the TCP data packet transmitted by the application is larger than a time threshold value, if so, the terminal equipment can switch the first SIM card to the second SIM card, and if not, the terminal equipment can indicate that the current data transmission is in a tolerable range, and can not switch the terminal equipment. The time threshold may be set according to actual requirements or empirical values, such as 250 ms, 230 ms, 276 ms, etc. The SIM card is switched when necessary, so that adverse effects caused by the SIM card switching to the user in the application use process can be reduced.
Further, when the acquired data transmission parameters meet the switching conditions corresponding to the real-time interactive application, the interactive operation time of the user can be detected, and if the interactive operation is not detected within the first duration, the first SIM card can be switched to the second SIM card. The first duration may also be set according to actual requirements or empirical values, for example, 5 seconds, 10 seconds, 13 seconds, etc. The first time length can also be set according to the network breaking time length for the SIM card switching process, and the longer the network breaking 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 break time length is, the smaller the influence on the user in the application using process is, and the shorter the set first time length 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 is switched at the moment, so that the adverse effect of the SIM card switching to the user in the application using process can be further reduced.
And the type II and the application type are resource preloading type applications. 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 a user is prevented from being blocked when playing and displaying multimedia data. Because the application can pre-load a part of resources, the user has low sensitivity to SIM card switching, but because the resource pre-load application has high demand on network resources, if the data transmission capability of the first SIM card carrying the data service is too bad, the use of the resource pre-load application can be influenced.
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 can not judge whether the RTT is larger than the time threshold, but can switch the first SIM card to the second SIM card when the TCP handshake success rate is detected to be smaller than the first threshold and the TCP retransmission rate is detected to be larger than the second threshold, so that the data transmission capacity of the terminal equipment when the pre-loading application is used can be improved, the set switching conditions are not too strict or too mild, and the influence of the 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 meet the switching conditions corresponding to the resource preloading class application, the data amount of the currently preloaded resource can be acquired. If the current preloaded resource is larger than the resource threshold, the preloaded resource data size is large enough, the user is not influenced when the SIM card is switched, and the first SIM card can be switched to the second SIM card. The resource threshold may also be set according to actual requirements or experience values, such as 2MB (megabytes), 0.5MB, 1.7MB, etc. The resource threshold value can be set according to the network disconnection time length of 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 off-network duration, the smaller the set resource threshold may be. The adverse effect of SIM card switching to the user in the application using process can be further reduced.
And the third application type is a page browsing application. The page browsing application can comprise a browser application, a reading application and the like, the page browsing application has small requirement on network resources, and the user has low sensitivity on SIM card switching in the application using process, so that the switching condition corresponding to the page browsing application can be a milder switching condition.
Alternatively, the handoff condition corresponding to the page view class 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 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, or multiple application types may set the same switching conditions, and the switching conditions are not limited to the above-mentioned types, and the embodiment of the present application is not limited to the application types and the switching conditions.
In some embodiments, the applications may include applications running in the foreground, which may refer to applications where the running interface may be seen on the screen of the terminal device, and/or applications running in the background, which may refer to applications where the running interface is not seen. For applications running on a terminal device, there may be, but are not limited to, the following:
1. only foreground applications exist running. If the application exists in the current terminal device and is running in the foreground, the data transmission parameters of the first SIM card for the foreground application can be obtained in the process that the foreground application is running in the foreground, and whether to switch the SIM card is judged according to the method described in the steps 402 to 406.
2. Only background applications exist running. If the applications in the current terminal equipment are all running in the background, the data transmission parameters of the first SIM card aiming at each background application can be obtained, and different applications can have the data transmission requirements with the network equipment during running, so that the data transmission parameters can be obtained according to the TCP data packets sent to the network equipment by each background application during running. The first SIM card can analyze the data transmission parameters of each background application and judge whether SIM card switching is needed.
Optionally, a TCP handshake success rate and a 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 the proportion threshold value, the abnormal data transmission is a common phenomenon, and the network quality accessed through the first SIM card is poor currently, the first SIM card can be switched to the second SIM card.
3. And running a foreground application and a background application at the same time. Alternatively, only the data transmission parameters of the foreground application for the foreground application may be obtained during the foreground running process, and whether to switch the SIM card is determined according to the methods described in steps 402 to 406.
Optionally, in the running process of the foreground application, the data transmission parameters of the first SIM card for the foreground application may be obtained, and in the running process of each background application, the data transmission parameters of the first SIM card for each background application may be obtained. The method can analyze the data transmission parameters of the foreground application and the data transmission parameters of the background application at the same time and judge whether SIM card switching is needed. The TCP handshake success rate and the TCP retransmission rate of the foreground application can be obtained, and whether the foreground application has abnormal data transmission or not is judged according to the TCP handshake success rate and the TCP retransmission rate.
If the foreground application has abnormal data transmission, judging whether the background application has abnormal data transmission according to the TCP handshake success rate and the TCP retransmission rate of the background application. When the data transmission of the background application is normal, network resources occupied by the background application with normal data transmission can be obtained, if the occupied network resources are larger than a preset resource threshold value, the background application can be indicated to occupy too much network resources, the data transmission of the foreground application is affected, and the background application can be suspended or closed. Alternatively, the resource threshold may be set according to actual requirements, for example, 500kbps (kilobit rate), 687kbps, and the like.
Optionally, if the foreground application has abnormal data transmission, and meanwhile, the proportion of the abnormal data transmission of the background application is greater than a 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 stated that the abnormal data transmission is a common phenomenon, and the network quality accessed through the first SIM card is poor at present, and the first SIM card can be switched to the second SIM card.
