Embodiment 1

[0046] Such as figure 1 As shown, this embodiment provides a method for dual card switching, which is used in a terminal. The terminal includes a first card and a second card, the first card is the main card, and the second card is the secondary card. The method includes:

[0047] S1, judging whether the first card and the second card belong to the same network operator, and determining whether to enter step S2 according to the judging result;

[0048] Specifically, step S1 includes the following steps:

[0049] S11, respectively read the network numbers of the first card and the second card;

[0050] S12, judge whether the first card and the second card belong to the same network operator according to the network number: if yes, return to step S11, if not, enter step S2;

[0051]In this embodiment, the terminal includes a first card and a second card, and the user uses the first card as the main card for mobile data connection. After the terminal is powered on, read the ne...

Embodiment 2

[0068] This embodiment provides a dual-card switching device, which is used in a terminal. The terminal includes a first card and a second card. The first card is a main card, and the second card is a secondary card. The device includes: a first judgment module 31, The second judging module 32 and the switching module 33,

[0069] The first judging module 31 is used to judge whether the first card and the second card belong to the same network operator, and determine whether to trigger the second judging module 32 according to the judging result;

[0070] The first judging module 31 is specifically configured to perform the following steps:

[0071] S11, respectively read the network numbers of the first card and the second card;

[0072] S12, judge whether the first card and the second card belong to the same network operator according to the network number: if yes, return to step S11, if not, trigger the second judgment module 32;

[0073] In this embodiment, the terminal ...

Embodiment 3

[0090] This embodiment provides a terminal device, including a memory and a processor. The memory stores instructions, and the processor executes the instructions to implement a method for switching between dual cards applied to a terminal.

[0091] Wherein, the memory is electrically connected with the processor, the memory can be a flash memory or a read-only memory or other memory, and the processor can be a central processing unit or a single-chip microcomputer.

Abstract

The invention discloses a double-card switching method which is used for a terminal, the terminal comprises a first card and a second card, the first card is a main card, the second card is an auxiliary card, and the method comprises the following steps: S1, judging whether the first card and the second card belong to the same network operator or not, and determining whether to enter a step S2 ornot according to a judgment result; S2, judging the advantages and disadvantages of the currently accessed network types of the first card and the second card, and determining whether to enter the step S3 or not according to a judgment result; and S3, switching the second card into the main card, and returning to the step S2. Correspondingly, the invention further provides a double-card switchingdevice and terminal equipment. The problem that in the prior art, a user needs to manually select a card with good signal coverage as a main card for mobile data transmission, and operation is tediouscan be solved.

Description

technical field [0001] The present invention relates to the technical field of communication, and in particular to a method, device and terminal equipment for dual-card switching. Background technique [0002] At present, more than 90% of the smart phones on the market support dual-card models. Users can manually select any card in the dual-card slot to set it as the main card (that is, the card for mobile data transmission is called the main card) , and the other is called the secondary card, which can only make calls and send text messages, but cannot transmit mobile data. [0003] People often encounter such a situation in the process of daily use of mobile phones: different network operators have large differences in signal coverage in urban buildings, underground garages, suburbs, remote mountainous areas and other areas. The root cause of this situation is mainly that the number of base stations of different network operators and the distribution of base stations are ...
