Description

Technical Field

[0001] The present application relates to the field of terminal technology, and in particular to a cellular data switching method and device. Background Art

[0002] With the development of mobile communication technology and the popularization of smart mobile terminals, mobile terminals are playing an increasingly important role in users' lives. Users can engage in social activities through various applications on their mobile terminals. While applications bring convenience to users' lives, they also consume a large amount of data traffic. In view of this, operators have introduced dedicated data plans based on general data plans to enrich the variety of data plans. Dedicated data plans can only be used in specific applications and have certain restrictions. However, dedicated data plans are generally cheaper than general data plans.

[0003] Existing multi-mode mobile terminals, such as dual-SIM dual-standby, are widely used. Different data SIM cards support different free data applications. When using the cellular data of one data SIM card, if you enable the free data application supported by that card, there will be no charge or a lower charge. However, if you enable the free data application supported by another data SIM card at the same time, you will incur a charge. However, when using the terminal, users often forget to switch to the cellular data of the corresponding low-cost or free data SIM card, resulting in a waste of data SIM package resources and unnecessary losses.

[0043] In order to make the purpose, technical solutions and advantages of the application more clear, the technical solutions in the application will be described clearly and completely in the following with the drawings in the embodiments of the application. Obviously, the described embodiments are some embodiments of the application, not all embodiments. Based on the embodiments in the application, all other embodiments obtained by those skilled in the art without creative labor are within the protection scope of the application.

[0044] In the following, the cellular data switching method and device provided by the embodiment of the application will be described and explained in detail through several specific embodiments.

[0045] In one embodiment, a cellular data switching method is provided, which is applied to a mobile terminal that supports at least two data SIM cards and is used to switch cellular data. The mobile terminal may be a mobile phone, a laptop computer, or the like.

[0046] like Figure 1 As shown, a cellular data switching method provided in this embodiment includes:

[0047] Step 101, identifying target applications corresponding to the first traffic card in an inactive state from among the applications opened on the mobile terminal;

[0048] Step 102: Determine whether the traffic statistics of each target application reaches a threshold, and switch the mobile terminal to cellular data using the first traffic card.

[0049] By identifying the target applications corresponding to the first traffic card in a non-working state from the applications opened by the mobile terminal, and when it is detected that the traffic statistics of each target application reach a threshold, the mobile terminal is switched to the cellular data using the first traffic card. In this way, when the user frequently uses the target applications corresponding to the first traffic card in a non-working state, it can automatically switch to the cellular data of the first traffic card, avoiding the problem of additional charges for data communication services caused by the user forgetting to switch or failing to switch to cellular data in time, and reducing the waste of traffic card resources.

[0050] In one embodiment, the mobile terminal pre-stores the correspondence between each traffic card and the free traffic application supported by the traffic card. For example, the traffic card of operator A provides an exclusive traffic package, supports free traffic services for app-1, app-2, and app-3, and the traffic of other applications is charged with universal traffic. The traffic card of operator B provides an exclusive traffic package, supports free traffic services for app-5 and app-6, and the traffic of other apps is charged with universal traffic. In this way, assuming that a user considers economics and personal usage habits, he can pre-set app-1, app-2, and app-3 in the mobile terminal to give priority to cellular data A of the traffic card of operator A; app-5, app-6, and app-7 give priority to cellular data B of the traffic card of operator B. Then it can be concluded that the applications associated with cellular data A and cellular data B are as follows:

[0051]

[0052] In this way, you can set the traffic card of operator A to correspond to applications app-1, app-2, and app-3, and the traffic card of operator B to correspond to applications app-4, app-5, and app-6.

[0053] During the process of turning on the mobile terminal, a data card that is not in operation can be marked as the first data card, while a data card that is in operation can be marked as the second data card. During the process of turning on the mobile terminal, each open application of the mobile terminal can be obtained and then identified to detect whether there are target applications corresponding to the inactive first data card among the open applications of the mobile terminal. If not, there is no need to switch to cellular data. If so, traffic statistics are collected for each target application.

[0054] For example, assuming that among the applications opened by the mobile terminal, there are three applications, app-5, app-6, and app-7, and these three applications correspond to the traffic card of operator B, and the traffic card of operator B is in a non-working state, then the three applications app-5, app-6, and app-7 can be marked as target applications, and traffic statistics can be performed on the three target applications app-5, app-6, and app-7.

[0055] Among them, the starting time for traffic statistics of each target application can be after each cellular data switch. For example, after each cellular data switch, all traffic statistics are set to 0, and then a new round of traffic statistics is started. For example, assuming that the cellular data of the traffic card of operator A is used after the switch, and the traffic card of operator B is in a non-working state, then when switching to the cellular data of the traffic card of operator A, all traffic statistics are set to 0. At the same time, starting from the cellular data of the traffic card switched to operator A, traffic statistics are performed for each target application corresponding to the traffic card of operator B that is not in a working state within a period of time.

[0056] Considering that the mobile terminal may use wireless access, such as WIFI access, and WIFI access does not incur charges when using any application. Therefore, after identifying each target application, it is possible to first detect whether the mobile terminal is currently using cellular data to access the network. If the mobile terminal uses a wireless network to access the network, there is no need to switch to cellular data; if the mobile terminal uses cellular data to access the network, the traffic statistics of each target application are collected, so that when the traffic statistics of each target application reach a threshold, the mobile terminal is switched to cellular data using the first traffic card.

[0057] In order to make the switching of cellular data more in line with actual needs and improve the accuracy of the switching timing of cellular data, in one embodiment, the traffic statistics of each target application can be at least one of the following three: counting the average rate at which any target application generates traffic within a first preset time period, counting the total traffic used by any target application within a second preset time period, and counting the total duration for which any target application generates traffic within a third preset time period.

[0058] Specifically, such as Figure 2 As shown, after determining each target application, traffic statistics for each target application can be turned on to execute step 201: counting the average rate at which any target application generates traffic within the first preset time period; step 202: counting the total traffic used by any target application within the second preset time period. And step 203: counting the total duration for any target application to generate traffic within the third preset time period. Among them, if the average rate at which any target application generates traffic within the first preset time period reaches the preset rate, it can be determined that the traffic statistics for each target application reaches the threshold, at which point the cellular data switching stage can be entered. Alternatively, if the total traffic used by any target application within the second preset time period reaches the preset traffic, it can be determined that the traffic statistics for each target application reaches the threshold, at which point the cellular data switching stage can be entered. Alternatively,

[0059] If the total traffic used by any target application in the second preset period reaches the preset traffic, it can be determined that the traffic statistics of each target application have reached the threshold, and the cellular data switch can be started.

[0060] stage.

[0061] The first preset period, the second preset period, and the third preset period may be the same period, and the duration of the first preset period, the second preset period, and the third preset period may be set according to actual conditions.

[0062] For example, assume that the first traffic card currently in a non-working state is a traffic card of operator B, and the target applications corresponding to the traffic card of operator B are app-5, app-6, and app-,

[0063] 7, when the mobile terminal starts to use at least one of app-5, app-6, and app-7, traffic statistics are performed. Assume that there are the following three statistical results:

[0064] Scenario 1:

[0065]

[0066] Since the average rate of app-5 in the first preset time period reaches the preset rate, it can be determined that the traffic statistics of each target application reaches the threshold.

[0067] Scenario 2:

[0068]

[0069]

[0070] Since the total traffic generated by app-5 in the second time period exceeds the preset traffic, it can be determined that the traffic statistics of each target application reaches the threshold.

[0071] Scenario 3:

[0072]

[0073] Since the total duration for which app-7 generates traffic in the third time period exceeds the preset duration, it can be determined that the traffic statistics for each target application reaches the threshold.

[0074] After determining that the traffic statistics of each target application reach the threshold, the cellular data switching stage can be entered, such as directly switching the cellular data used by the mobile terminal from the cellular data of the second traffic card in working state to the cellular data of the first traffic card.

[0075] To further improve the accuracy of cellular data switching, in one embodiment, Figure 3 As shown, determining that the traffic statistics of each target application reaches a threshold, and switching the mobile terminal to cellular data using the first traffic card, includes:

[0076] Step 301: Determine whether the traffic statistics of each target application reaches a threshold, and obtain, from each application, associated applications corresponding to the second traffic card in working state;

[0077] Step 302: Determine that the traffic statistics of each associated application do not reach a preset value, and switch the cellular data used by the mobile terminal from the cellular data of the second traffic card to the cellular data of the first traffic card.

[0078] In one embodiment, after determining that the traffic statistics of each target application reaches a threshold, the associated applications corresponding to the second traffic card in working state can be identified from the applications opened on the mobile terminal.

[0079] If the second traffic card is a traffic card of operator A, and its corresponding applications are app-1, app-2, and app-3, then after determining that the traffic statistics of each target application have reached the threshold, identify whether there is at least one application among app-1, app-2, and app-3 among the applications opened by the mobile terminal. If at least one application among app-1, app-2, and app-3 does not exist among the applications opened by the mobile terminal, the cellular data used by the mobile terminal will be directly switched from the cellular data of the second traffic card to the cellular data of the first traffic card. If at least one application among app-1, app-2, and app-3 is identified, the identified application will be marked as an associated application corresponding to the second traffic card.

[0080] After acquiring each associated application, traffic statistics are performed on each associated application. The starting time for traffic statistics of each associated application is the same as the actual time for traffic statistics of the target application. For example, assuming that the cellular data of the traffic card of operator A is used after switching, and the traffic card of operator B is in a non-working state, then when switching to the cellular data of the traffic card of operator A, all traffic statistics are set to 0. At the same time, starting from the switching to the cellular data of the traffic card of operator A, traffic statistics are performed for each associated application corresponding to the traffic card of operator A in a working state within a period of time.

[0081] Among them, the traffic statistics of each associated application can be at least one of the following three: counting the average rate at which any associated application generates traffic within the first preset time period, counting the total traffic used by any associated application within the second preset time period, and counting the total duration for which any associated application generates traffic within the third preset time period.

[0082] Specifically, after obtaining each associated application, the average rate at which any target application generates traffic within the first preset time period can be counted; the total traffic used by any associated application within the second preset time period can be counted; and the total duration for any associated application to generate traffic within the third preset time period can be counted.

[0083] Among them, if the average rate at which each associated application generates traffic within the first preset time period does not exceed the average rate, it is determined that the traffic statistics of each associated application do not reach the preset value. At this time, the cellular data used by the mobile terminal can be switched from the cellular data of the second traffic card to the cellular data of the first traffic card.

[0084] Alternatively, if the total duration of traffic generated by each associated application within the second preset time period does not exceed the preset duration, it is determined that the traffic statistics of each associated application have not reached the preset value. In this case, the cellular data used by the mobile terminal can be switched from the cellular data of the second data card to the cellular data of the first data card.

[0085] Alternatively, if the total traffic used by each associated application during the third preset time period does not exceed the preset traffic, it is determined that the traffic statistics of each associated application have not reached the preset value. In this case, the cellular data used by the mobile terminal can be switched from the cellular data of the second traffic card to the cellular data of the first traffic card.

[0086] Alternatively, if the average rate of traffic generated by each associated application during the first preset time period does not exceed the average rate, and the total duration of traffic generated by each associated application during the second preset time period does not exceed the preset duration, and the total traffic used by each associated application during the third preset time period does not exceed the preset traffic, then it is determined that the traffic statistics for each associated application have not reached the preset value. In this case, the cellular data used by the mobile terminal can be switched from the cellular data of the second data card to the cellular data of the first data card.

[0087] In one embodiment, if it is determined that the traffic statistics of each associated application have reached a preset value, the cellular data is not switched and the cellular data of the second traffic card is used.
