Description

Technical Field

[0001] The present disclosure relates to the field of terminal technology, and in particular to a method, device, electronic device, and storage medium for switching dual-card data links. Background Art

[0002] With the development and popularization of mobile Internet, more and more people use mobile phones to surf the Internet, and data services are particularly important. Currently, dual-SIM dual-pass capable mobile phones can use both SIM cards for calls and data services at the same time. Although dual-SIM dual-pass capable mobile phones can establish two data links at the same time, the power consumption is relatively large, resulting in poor battery life. Generally, only one data link is established during use.

[0003] The wireless environment in different places in life is different. In one place, the network of operator A is poor, but the network of operator B may be very good. If you use A for data services in this place, the experience will inevitably be poor. Therefore, the data card needs to be automatically switched to the card of operator B. The current data card switching process is: first disconnect the link of the original default data card, and then establish the data link of the secondary card. The switching process will cause a short network disconnection. If the user is playing games or live broadcasting, there will be high latency or freezes, and the experience is not good.

[0060] Embodiments of the present disclosure are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present disclosure, and should not be construed as limiting the present disclosure.

[0061] With the popularization of smart terminal devices and the development of image processing, people's technical requirements for various aspects of terminals are also rising. When switching between dual SIM cards in a terminal, the data link of the main data card will be disconnected first, and then the data link of the secondary card will be established. There will be a short period of no network in the middle, causing packet loss and game lag. Therefore, a dual SIM data link switching method based on dual SIM dual active (DSDA) technology for seamless dual SIM switching is needed.

[0062] Therefore, in order to solve the problems existing in the related art, the present disclosure proposes a dual-card data link switching method, in which, when it is determined that the signal strength of the first data card is less than a preset signal strength threshold, it is judged whether the signal strength of the second data card meets the preset switching condition, and the data transmission of the terminal is performed through the first data link established by the first data card; if the signal strength of the second data card meets the preset switching condition, the second data link corresponding to the second data card is opened; wherein the first data card and the second data card are in a dual-card dual-pass state; and the first data link corresponding to the first data card is controlled to be closed. Dual-card seamless switching processing is realized.

[0074] Figure 1 The present invention provides a flowchart of a dual-card data link switching method. The method can be applied to application scenarios such as smart terminals, for example, executed by a terminal with integrated dual-card dual-pass function, and the present invention is not limited thereto. Figure 1 As shown, the dual-card data link switching method includes steps 101-103.

[0075] Step 101: when it is determined that the signal strength of the first data card is less than a preset signal strength threshold, it is determined whether the signal strength of the second data card meets a preset switching condition, and data transmission of the terminal is performed through a first data link established by the first data card.

[0076] The smart terminal to which the embodiments of the present disclosure apply shall be equipped with dual SIM (Subscriber Identity Module) cards and have the function of DSDA. The first data card described in the embodiments of the present application is the data card (SIM card) used by the terminal when currently performing data transmission, which can also be called the main card, and the second data card is the data card (SIM card) of the terminal that does not open the data link, which can also be called the secondary card.

[0077] In some embodiments, when the terminal uses a mobile communication network to perform data transmission, that is, the terminal is currently using the first data link corresponding to the first data card to perform data transmission, the signal strength of the first data card in the terminal is monitored, and it is determined whether the signal strength of the first data card is less than a preset signal strength threshold. When it is determined that the signal strength of the first data card is less than the preset signal strength threshold, it means that the signal strength of the first data card in the wireless environment of the terminal at the current location is relatively weak, and the signal strength of the second data card needs to be judged. When it is determined that the signal strength of the first data card is greater than or equal to the preset signal strength threshold, it means that the signal strength of the first data card in the wireless environment of the terminal at the current location is relatively strong, and there is no need to perform data link switching.

[0078] In some embodiments, the preset signal strength threshold is an empirical value and needs to be flexibly set according to whether the data card is 4G or 5G. The preset signal strength threshold is used to define the weak signal threshold of the first data card and the second data card.

[0079] Illustratively, the embodiment of the present disclosure provides an example of an exemplary signal strength threshold, as shown in Table 1. It should be noted that Table 1 is only an illustrative example, and is not a limitation of specific values. In actual application scenarios, it can be flexibly configured according to actual needs.

[0080] Table 1

[0081] LTE(4G) NR(5G) weak signal RSRP<=-110 RSRP<=-105 Strong signal RSRP>=-97 RSRP>=-85

[0082] RSRP (Reference Singal Receiving Power) is the linear average of the power contribution (unit: w) of the resource elements carrying the cell-specific reference signal on the specified measurement frequency band (the protocol stipulates that RSRP refers to the energy per RE).

[0083] When it is determined that the signal strength of the first data card is less than the preset signal strength threshold, it is determined whether the signal strength of the second data card meets the preset switching condition, and the preset switching condition is determined according to the number of times the signal strength of the second data card is greater than the signal strength of the first data card within a preset time period. The purpose of such a setting is to prevent errors caused by the comparison result of the signal strength of the second data card with the signal strength of the first data card, thereby failing to solve the problem of freezing.

[0084] Step 102: if the signal strength of the second data card meets the preset switching condition, start the second data link corresponding to the second data card; wherein the first data card and the second data card are in a dual-card dual-pass state.

[0085] After determining that the signal strength of the first data card is less than the signal strength of the second data card in the environment where the terminal is located, the terminal notifies to switch the default data card to the second data card, that is, to open the second data link corresponding to the second data card.

[0086] After the second data card establishes the second data link, at this moment, the terminal simultaneously has the first data link corresponding to the first data card and the second data link corresponding to the second data card, forming dual data coexistence. The intermediate state of dual data coexistence can realize dual card seamless switching based on DSDA technology.

[0087] For a clearer understanding of dual data coexistence, please refer to Figure 2 , Figure 2 A schematic diagram of a terminal dual data coexistence provided by an embodiment of the present disclosure. Figure 2 It can be clearly seen that compared with before optimization, when the optimized first data card switches to the data link of the second data card, there is an intermediate state where dual data coexist, to ensure that there will be no short-term network-free state, so as to achieve the data transmission process without causing packet loss, freeze / high delay and other problems.

[0088] Step 103: Control closing the first data link corresponding to the first data card.

[0089] After ensuring that the current data transmission of the terminal is transmitted based on the second data link, the first data link corresponding to the first data card is cut off, that is, the main card data link is disconnected.

[0090] According to the dual-card data link switching method proposed in the present disclosure, the method includes, when determining that the signal strength of the first data card is less than the preset signal strength threshold, judging whether the signal strength of the second data card meets the preset switching condition, and performing terminal data transmission through the first data link established by the first data card; if the signal strength of the second data card meets the preset switching condition, then opening the second data link corresponding to the second data card; wherein the first data card and the second data card are in a dual-card dual-pass state; and controlling the closing of the first data link corresponding to the first data card. Compared with the related art, the present disclosure first establishes the second data link of the second data card when performing dual-card switching, forming an intermediate state where dual data links (the first data link and the second data link) coexist, and then disconnects the first data link corresponding to the first data card, solving the problem of freezing / high latency.

[0091] Figure 3 The following further shows a flow chart of a method for switching a dual-card data link proposed in the present disclosure. Figure 1 The embodiment shown further explains step 101. Figure 3 The following steps may be included:

[0092] Step 201, determining the number of times the signal strength of the second data card is greater than the signal strength of the first data card within a preset time period; and determining whether the number is greater than a preset number threshold.

[0093] If it is determined that the number is greater than the preset number threshold, step 202 is executed; if it is determined that the number is less than or equal to the preset number threshold, step 203 is executed.

[0094] The purpose of determining the number of times the signal strength of the second data card is greater than the signal strength of the first data card within a preset time period is to prevent errors in switching data links caused by a single signal strength comparison result.

[0095] In some embodiments, the preset number threshold is an empirical value. The higher the preset number threshold is set, the greater the requirement that the signal strength of the second data card must be higher than the signal strength of the first data card, and the signal strength of the second data card itself must be greater than or equal to the preset signal strength threshold.

[0096] For example, it is determined whether the signal strength of the second data card meets the strong signal condition. If it does, the dual-card signals for the next 30 seconds after the preset time are counted, and the statistical interval is 1 second. After 30 seconds, if the number of times the signal strength of the first data card is weak is greater than 60%, and the number of times the signal strength of the second data card is weak is less than 10%, it is determined that the signal strength of the first data card in the wireless environment at the current location is not as high as the signal strength of the second data card, so the default data card can be notified to switch to the second data card.

[0097] If the number of times the signal strength of the first data card is weak is less than or equal to 60%, and / or the number of times the signal strength of the second data card is weak is greater than or equal to 10%, it is determined that the signal strength of the first data card in the wireless environment of the current location is higher than the signal strength of the second data card. Therefore, there is no need to switch the data card, and the terminal continues to maintain data transmission based on the first data link of the first data card.

[0098] It should be noted that the above numerical values ​​are only exemplary descriptions and are not limitations on specific numerical values.

[0099] Step 202: Determine whether the signal strength of the second data card satisfies the preset switching condition.

[0100] Step 203: determine that the signal strength of the second data card does not meet the preset switching condition.

[0101] In some embodiments, as an illustration of application scenarios, for some applications in the terminal that have high demands for mobile data, short-term network conditions may cause a decrease in user experience, for example, when the application is a game scenario, a live broadcast scenario, or a video or voice call scenario.

[0102] In order to satisfy the end user's experience, the method described in the embodiment of the present application performs seamless switching in the preset whitelist, such as Figure 4 As shown, specifically including:

[0103] Step 301, obtaining identification information of the current application.

[0104] All applications in the terminal have identification information of the application, and the identification information is determined during installation.

[0105] Step 302: Determine whether the current application is an application for a switchable data card according to a preset white list and the identification information, wherein the preset white list records the applications for a switchable data card and the corresponding identification information.

[0106] If it is determined that the current application is an application for a switchable data card, step 303 is executed. If it is determined that the current application is not an application for a switchable data card, the process ends.

[0107] In some embodiments, the applications of the switchable data card and the corresponding identification information recorded in the preset whitelist can be customized, such as applications that support game scenarios, live broadcast scenarios, or video and voice call scenarios. Specifically, the embodiments of the present disclosure do not limit this.

[0108] When it is determined that the current application is not an application capable of switching data cards, seamless switching between the first data card and the second data card is not performed to save processing resources of the terminal.

[0109] Step 303: Open the second data link corresponding to the second data card.

[0110] The method for the terminal to open the second data link corresponding to the second data card may refer to any implementation method in the relevant technology, and the specific implementation method will not be described in detail in the embodiment of the present disclosure.

[0111] In some embodiments, when executing to open the second data link corresponding to the second data card, it can be implemented by but not limited to the following methods, including: determining whether the first data card and the second data card both support dual-card dual-pass and whether they are in the dual-card dual-pass state; when it is determined that the first data card and the second data card both support dual-card dual-pass and are in the dual-card dual-pass state, establishing the second data link corresponding to the second data card to perform data transmission based on the second data link.

[0112] In some embodiments, it is first determined whether the first data card and the second data card are 4G / 5G, because only when the dual cards are 4 / 5G can they have DSDA capabilities. On this basis, it is determined whether the terminal is in a DSDA state. When both the first data card and the second data card support dual-card dual-pass and are in the dual-card dual-pass state, a second data link for the second data card is established to form an intermediate state of dual data coexistence.

[0113] In some embodiments, before determining whether the signal strength of the second data card meets the preset switching condition, the current screen state of the terminal screen is identified. If the current screen state is a bright screen state, the signal strength of the first data card is monitored to determine the relationship between the signal strength of the first data card and the preset signal strength threshold.

[0114] If the current screen state is the screen off state, the dual-card data link switching method described in the embodiment of the present disclosure will not be executed.

[0115] When executing signal strength monitoring, any method in the relevant technology can be used to implement it. The specific details will not be repeated in the embodiments of the present application.

[0116] In some embodiments, the present application also provides a method for switching a dual-card data link. Figure 5 As shown, including:

[0117] Step 401, identifying the current screen state of the terminal screen.

[0118] If the current screen state is the screen-on state, execute step 402; if the current screen state is the screen-off state, end.

[0119] Step 402: monitor the signal strength of the first data card to determine the magnitude relationship between the signal strength of the first data card and the preset signal strength threshold. Perform data transmission on the terminal through the first data link established by the first data card.

[0120] If it is determined that the signal strength of the first data card is less than the preset signal strength threshold, step 403 is executed; if it is determined that the signal strength of the first data card is greater than or equal to the preset signal strength threshold, step 404 is executed.

[0121] Step 403: determine whether the signal strength of the second data card meets a preset switching condition.

[0122] If the signal strength of the second data card meets the preset switching condition, step 405 is executed; if the signal strength of the second data card does not meet the preset switching condition, step 404 is executed.

[0123] Step 404: Continue to transmit data through the first data link established by the first data card.

[0124] Step 405, obtaining identification information of the current application;

[0125] Step 406: Determine whether the current application is an application for a switchable data card according to a preset whitelist and the identification information, wherein the preset whitelist records the applications for a switchable data card and the corresponding identification information.

[0126] If it is determined that the current application is an application for which the data card can be switched, step 407 is executed. If it is determined that the current application is an application for which the data card cannot be switched, the process ends.

[0127] Step 407: Open the second data link corresponding to the second data card.

[0128] In some embodiments, after the terminal switches to the second data link, it is still necessary to monitor the signal strength of the second data link. After determining that the signal strength of the second data card is less than the signal strength of the first data card within a preset time, it is also necessary to switch using the switching method described in the present disclosure. That is, the switching of the dual-card data link is not a one-time switching without monitoring or switching, but a process of continuous monitoring and / or switching (i.e., cyclic execution). Figure 5 process).

[0129] Step 408: Control closing the first data link corresponding to the first data card.
