Detailed ways

In order to enable those skilled in the art to better understand the solutions of the application, the technical solutions in the embodiments of the application will be clearly and completely described below in conjunction with the drawings in the embodiments of the application. Obviously, the described embodiments are only It is a part of the embodiments of this application, but not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by a person of ordinary skill in the art without creative work shall fall within the protection scope of this application.

FIG. 1 shows a schematic diagram of an application scenario of a data card switching method or a data card switching device applied to an embodiment of the present application. When two cards are installed in a terminal that supports dual cards, the terminal can display the dual card logo on the display screen. Among them, both cards can be used as data cards, but only one card can be used as a data card at the same time.

According to some embodiments, the dual cards installed in the terminal may be, for example, an A data card and a B data card. The terminal can set the data card currently in use. For example, the terminal may set the data card installed in the card slot 1 as the currently used data card. When the user installs the A data card in the card slot 1 and the B data card in the card slot 2, the terminal can use the A data card as the currently used data card by default, that is, the terminal can default the A data card as the first data card.

It is easy to understand that when the terminal switches between the first data card and the second data card, the terminal needs to receive a user's switching instruction for the first data card and the second data card, and the terminal can switch the data card based on the switching instruction. The switching instruction may be, for example, a click switching instruction. When the terminal receives the click switch instruction input by the user on the display screen, the terminal can set the B data card as the first data card and the A data card as the second data card.

Optionally, when the network quality of the first data card in the terminal is extremely poor, the terminal may send a prompt message, which is used to prompt the user whether to switch the data card. When the user chooses to switch the data card, the user can input a switching instruction for the data card, and the terminal can switch the data card based on the received switching instruction. When the terminal completes the data card switching, the user can use the second data card to watch videos or browse information. However, in this process, the terminal needs to receive a switching instruction for the data card input, which results in a complicated data card switching operation and low data card switching efficiency. In addition, when the terminal performs data card switching based on the switching instruction input by the user for the data card, the user only chooses based on experience and does not fully consider the information of the first data card and the second data card, resulting in lower signal instructions for the data card after switching , The problem of poor user experience.

The method for switching the data card provided by the embodiment of the present application will be described in detail below with reference to FIG. 2 to FIG. 10. Fig. 2-Fig. 10 The execution subject of the embodiment shown in Fig. 10 may be, for example, a terminal.

Please refer to FIG. 2, which provides a schematic flowchart of a data card switching method according to an embodiment of the present application. As shown in FIG. 2, the method of the embodiment of the present application may include the following steps S101 to S102.

S101: Acquire a first signal strength value and a first data link quality of a first data card, and acquire a second signal strength value and a second data link quality of a second data card.

According to some embodiments, the first data card refers to a data card corresponding to cellular data currently used by a terminal that supports dual cards. The first data card may be set when the terminal leaves the factory, or may be set based on a user's setting instruction. The signal strength value refers to the received signal strength indicator value, which is used to characterize the physical quantity of the transmitted signal strength of the data card receiving signal transmission source.

It is easy to understand that the first signal strength value refers to the signal strength value corresponding to the first data card, and does not specifically refer to a certain fixed value. For example, the first signal strength value of the first data card may be -105dB, and the first signal strength value of the first data card may also be -115dB. The second signal strength value refers to the signal strength value corresponding to the second data card, and does not specifically refer to a fixed value. For example, the second signal strength value of the second data card may be -115dB, and the second signal strength value of the second data card may also be -118dB.

Optionally, the data link quality includes, but is not limited to, the data delay of the data card, the network standard, and so on. The data delay may be round-trip delay, for example. Round-Trip Time (RTT). The round-trip delay is composed of three parts: the propagation time of the link (propagation delay), the processing time of the end system, and the queuing and processing time (queuing delay) in the router cache. Among them, the values of the first two parts are relatively fixed for a TCP connection, and the queuing and processing time in the router cache will change with the change of the entire network congestion. Therefore, the change in the round-trip delay reflects the degree of network congestion to a certain extent, and the smaller the round-trip delay, the better the quality of the data link.

According to some embodiments, the first data link quality may be, for example, the first round-trip delay corresponding to the first data card, and does not specifically refer to a certain fixed value. The second data link quality may be, for example, the second round-trip delay corresponding to the second data card, and does not specifically refer to a certain fixed value. The first round-trip time delay represents the total time delay experienced since the terminal uses the first data card to send data to when the terminal receives the confirmation information of the data.

It is easy to understand that when the first data card is a data main card and the second data card is a data secondary card, the terminal can only use the data main card to transmit data services. When the first data card is a data main card and the second data card is a data secondary card, the terminal can also use the data primary card and the data secondary card to transmit data services at the same time. When the terminal uses the main data card and the auxiliary data card to transmit data services at the same time, the terminal can determine the data service transmission volume of the main data card and the auxiliary data card based on preset rules. The embodiment of the application defaults that the first data card is the main data card, and the second data card is the secondary data card.

Optionally, when the terminal uses the first data card to transmit data services, the terminal may obtain the first signal strength value and the first round-trip delay of the first data card, and obtain the second signal strength value of the second data card And the second round-trip delay.

According to some embodiments, the terminal supporting dual cards may be Q data cards and R data cards, for example. Based on the factory settings, the terminal can set the first data card as the main data card by default. Based on the factory settings, the terminal can also set the Q data card as the first data card and the R data card as the second data card. When the terminal uses the Q data card as the main data card for data transmission based on the factory settings, the terminal can obtain the first signal strength value and the first round-trip delay of the Q data card, and obtain the second signal strength value and the second signal strength of the R data card. Round trip delay. The first signal strength value of the Q data card obtained by the terminal may be, for example, -110dB, the first round-trip delay may be, for example, 500ms, the second signal strength value of the R data card may be, for example, -118dB, and the second round-trip delay may be, for example, It can be 550ms.

S102: Perform switching between the first data card and the second data card based on the first signal strength value, the second signal strength value, the first data link quality, and the second data link quality.

According to some embodiments, when the terminal obtains the first signal strength value and the first data link quality of the first data card, and obtains the second signal strength value and the second data link quality of the second data card, the terminal may be based on The acquired first signal strength value, second signal strength value, first data link quality, and second data link quality are used to switch between the first data card and the second data card.

It is easy to understand that when the terminal obtains the first signal strength value and the first data link quality of the first data card, and obtains the second signal strength value and the second data link quality of the second data card, the terminal can The first signal strength value and the second signal strength value are compared with a plurality of preset signal threshold values to obtain a first comparison result. When the first comparison result does not meet the preset requirement, the terminal may switch the data card based on the first data link quality and the second data link quality.

Optionally, when the Q data card is the first data card and the R data card is the second data card, the first signal strength value of the Q data card acquired by the terminal may be, for example, -120dB, and the first round-trip delay may be, for example, 500ms, the second signal strength value of the R data card may be -119dB, for example, and the second round-trip delay may be 450ms, for example. When the terminal determines that the first signal strength value is -120dB, and the second signal strength value may be, for example, -119dB, the terminal determines that the second round-trip delay is less than the first round-trip delay, and the terminal can switch the data card, that is, the terminal will R The data card is switched to the first data card, and the Q data card is switched to the second data card, that is, the terminal uses the R data card as the main data card and the Q data card as the secondary data card.

According to some embodiments, when the terminal switches between the first data card and the second data card, the terminal may send a prompt message for prompting whether to switch between the first data card and the second data card. When the terminal receives the confirmation information for the prompt information, the terminal can switch between the first data card and the second data card. For example, before the terminal switches between the first data card and the second data card, the Q data card is the first data card, and the R data card is the second data card. When the terminal switches between the first data card and the second data card, the prompt information sent by the terminal may be, for example, whether the R data card is the first data card and the Q data card is the second data card. At this time, an example schematic diagram of the terminal interface may be as shown in FIG. 3. When the terminal receives the confirmation message for the prompt message, the terminal can switch the R data card to the first data card and the Q data card to the second data card, that is, the terminal can use the R data card as the main data card for data services transmission.

The embodiment of the present application provides a data card switching method. The terminal can obtain the first signal strength value and the first data link quality of the first data card, and the second signal strength value and the second signal strength value of the second data card. In the case of data link quality, switching between the first data card and the second data card is performed based on the first signal strength value, the second signal strength value, the first data link quality, and the second data link quality. Therefore, the terminal can directly switch the data card based on the first signal strength value and the first data link quality of the first data card and the second signal strength value and the second data link quality of the second data card, without the need to receive users The switching instruction for the data card can reduce the switching steps of the data card, reduce the switching time of the data card, and improve the switching efficiency of the data card, thereby improving the user experience. In addition, the terminal performs data card switching based on the first signal strength value and the first data link quality of the first data card and the second signal strength value and the second data link quality of the second data card, which can improve data card switching. The accuracy of the data card reduces the instability of the data card network after the user switches the data card based on experience, thereby improving the user experience.

S201: Acquire the first signal strength value and the first data link quality of the first data card, and acquire the second signal strength value and the second data link quality of the second data card.

According to some embodiments, when the terminal obtains the first signal strength value and the first data link quality of the first data card, and obtains the second signal strength value and the second data link quality of the second data card, the terminal may set the signal Threshold. The signal threshold may be set by the terminal based on the magnitude of the signal strength value. The signal threshold set by the terminal includes at least a first signal threshold, a second signal threshold, a third signal threshold, and a fourth signal threshold. The number of signal thresholds set by the terminal may be determined based on actual usage conditions. For example, the number of signal thresholds set by the terminal may be four or six.

It is easy to understand that, for example, the first signal threshold set by the terminal based on the magnitude of the signal strength value is -105dB, the second signal threshold is -114dB, the third signal threshold is -118dB, and the fourth signal threshold is -120dB.

According to some embodiments, the first data link quality may be, for example, the first round-trip delay corresponding to the first data card, and does not specifically refer to a certain fixed value. The second data link quality may be, for example, the second round-trip delay corresponding to the second data card, and does not specifically refer to a certain fixed value. The first data link quality in the embodiment of the present application may be, for example, the first round-trip delay, and the second data quality may be, for example, the second round-trip delay.

It is easy to understand that when the first data card is a data main card and the second data card is a data secondary card, the terminal can only use the data main card to transmit data services. When the first data card is a data main card and the second data card is a data secondary card, the terminal can also use the data primary card and the data secondary card to transmit data services at the same time. The embodiment of the application defaults that the first data card is the main data card, and the second data card is the secondary data card.

The first signal strength value of the D data card obtained by the terminal may be, for example, -104dB, and the second signal strength value of the F data card may be, for example, -105dB. When the terminal detects that the first signal strength value -104dB is greater than the first signal threshold -105dB, the terminal keeps the first data card and the second data card unchanged, that is, the D data card is the main data card, and the F data card is the secondary data card. .
