Both the first card slot module 15 and the second card slot module 16 can be installed with a SIM card, so that the electronic device 1 can support dual-card dual-standby function.
In one embodiment, the processor 13 may include a control pin (not shown). The control pin may control the power module 17 to power up the first card slot module 15 or power up the second card slot module 16. When the level of the control pin is the first level, the power module 17 is only powered on the first card slot module 15, and at this time, the second card slot module 16 is powered off (i.e. the second card slot module 16 is in a power-off state, and the second card slot module 16 does not consume power), and the electronic device 1 is accessed to the operator network through the SIM card installed in the first card slot module 15.

In one embodiment, the first level may be a high level (greater than a first predetermined voltage, such as greater than 3.3V), and the second level may be a low level (less than a second predetermined voltage, such as less than 0.4V). In other embodiments, the first level may be a low level, and the second level may be a high level.
In an embodiment, the control pin may not be disposed on the processor 13, and the control pin is a signal pin of another chip of the electronic device 1. The control pin is preferably a GPIO pin.
Fig. 2 is a functional block diagram of a dual card switching device 100 according to a first embodiment of the present invention.
In this embodiment, the dual card switching apparatus 100 includes a series of computer program instructions stored on the memory 12, and when the computer program instructions are executed by the processor 13, the dual card switching operation of the embodiments of the present invention can be implemented, for example, the dual card switching apparatus 100 can be operated in the electronic apparatus 1. In some embodiments, the dual card switching apparatus 100 may be divided into one or more modules based on the particular operations implemented by the portions of the computer program instructions. For example, in fig. 2, the dual card switching apparatus 100 may be divided into a switching module 101, a control module 102 and a determining module 103. Wherein:
the switching module 101 is configured to switch the level of the control pin from a first level to a second level when receiving a switching instruction for switching the SIM card.
In an embodiment, the switching instruction for switching the SIM card may be generated by a user performing a SIM switching operation on the electronic apparatus 1, such as clicking a SIM switching icon. The user may also notify the electronic apparatus 1 to perform the SIM card switching operation through an at (attention) command or other network data command. Assuming that the level of the control pin is a first level before a switching instruction for switching the SIM card is received, when the switching instruction for switching the SIM card is received, the switching module 101 switches the level of the control pin from the first level to a second level.
It can be understood that, if the level of the control pin is the second level before the switching instruction for switching the SIM card is received, the switching module 101 switches the level of the control pin from the second level to the first level when the switching instruction for switching the SIM card is received.
The control module 102 is configured to power down the first card slot module 15 and power up the second card slot module 16 when the level of the control pin is the second level, so that the electronic device 1 accesses the first operator network through the SIM card installed in the second card slot module 16.
In one embodiment, when the level of the control pin is a second level, the control module 102 powers down the first card slot module 15 and powers up the second card slot module 16. At this time, the first card slot module 15 is in a power-off state, the second card slot module 16 is in a power-on state, and the electronic device 1 accesses the first operator network through the SIM card installed in the second card slot module 16.
For example, the first card slot module 15 is equipped with a first SIM card, and the second card slot module 16 is equipped with a second SIM card. When the level of the control pin is the second level, the first card slot module 15 is in a power-down state, the second card slot module 16 is in a power-up state, and the electronic device 1 accesses the first operator network through the second SIM card installed in the second card slot module 16. The first card slot module 15 corresponding to the first SIM card which is not used temporarily is powered off, so that the power of the electronic device 1 can be saved, and the operation power consumption of the electronic device 1 can be reduced.
The control module 102 is further configured to, when the level of the control pin is a first level, power up the first card slot module 15 and power down the second card slot module 16, so that the electronic device 1 accesses the second operator network through the SIM card installed in the first card slot module 15.
In one embodiment, when the level of the control pin is a first level, the control module 102 powers up the first card slot module 15 and powers down the second card slot module 16. At this time, the first card slot module 15 is in a power-on state, the second card slot module 16 is in a power-off state, and the electronic device 1 accesses the second operator network through the SIM card installed in the first card slot module 15. That is, the electronic device 1 accesses the second carrier network through the first SIM card installed in the first card slot module 15. The second card slot module 16 corresponding to the second SIM card which is not used temporarily is powered off, so that the power of the electronic device 1 can be saved, and the operation power consumption of the electronic device 1 can be reduced
In an embodiment, the first operator network and the second operator network may be the same operator network or different operator networks.
The control module 102 is further configured to set the level of the control pin to the first level when the electronic apparatus 1 is in a power-on state, so as to power on the first card slot module 15.
In an embodiment, when the electronic device 1 is in the power-on state, a card slot module needs to be selected for the electronic device 1 first, and at this time, the control module 102 sets the level of the control pin to the first level, so as to power on the first card slot module 15, that is, the first card slot module 15 is used as an initial card slot module. At this time, the first card slot module 15 is in a power-on state, the second card slot module 16 is in a power-off state, and the electronic device 1 accesses the second operator network through the SIM card installed in the first card slot module 15.
It can be understood that, when the electronic device 1 is in the power-on state, the control module 102 may also set the level of the control pin to be the second level, so as to power on the second card slot module 16, that is, the second card slot module 16 is used as the initial card slot module.
The determining module 103 is configured to determine whether the SIM card is detected within a first preset time after the first card slot module 15 is powered on.
In one embodiment, when the electronic device 1 is powered on and the first card slot module 15 is powered on, the determining module 103 determines whether the SIM card is detected within a first preset time after the first card slot module 15 is powered on. If the SIM card is detected within the first preset time, it indicates that the electronic apparatus 1 may attempt to access the carrier network through the SIM card installed in the first card-slot module 15. If the SIM card is not detected within the first preset time, it indicates that the first card slot module 15 may not have the SIM card installed or cannot read the SIM card installed in the first card slot module 15, and at this time, a card slot module switching operation needs to be performed, so that the electronic device 1 may attempt to access the operator network through the SIM card installed in the second card slot module 16. The first preset time may be set according to an actual requirement, for example, the first preset time is 10 seconds.
The control module 102 is further configured to switch the level of the control pin from a first level to a second level when the SIM card is not detected within the first preset time.
In an embodiment, since the SIM card is not detected within the first preset time, the control module 102 switches the level of the control pin from the first level to the second level, the first card slot module 15 becomes the power-down state, the second card slot module 16 becomes the power-up state, and the electronic device 1 attempts to access the carrier network through the SIM card installed in the second card slot module 16.
In an embodiment, after the electronic device 1 accesses the operator network through an SIM, a network disconnection state (network disconnection occurs) may occur, and at this time, the electronic device 1 may try to switch the card slot module, try to access the operator network through SIM cards installed in other card slot modules, and avoid that the electronic device 1 is always in the network disconnection state. For example, the first card slot module 15 is configured to install a SIM card of a first operator, the second card slot module 16 is configured to install a SIM card of a second operator, and at a certain location, there may be no signal from the first operator and a signal from the second operator, and at this time, if the electronic device 1 selects the SIM card of the first operator to access the operator network, a network disconnection situation may occur, and the electronic device 1 may attempt to select the SIM card of the second operator to access the operator network.
When the electronic device 1 is detected to be offline, the control module 102 is further configured to count a current offline time of the electronic device 1. The time of each offline of the electronic device 1 is not accumulated, i.e. each offline time is counted from zero.
The judging module 103 is further configured to judge whether the current offline time exceeds a second preset time.
In an embodiment, when the current offline time exceeds a second preset time, the electronic device 1 may attempt to switch the card slot module, and attempt to access the carrier network through the SIM card installed in another card slot module. The second preset time may be set according to an actual requirement, for example, the second preset time is 12 seconds.
The control module 102 is further configured to change the level of the control pin when the current offline time exceeds the second preset time.
In an embodiment, if the electronic device 1 is disconnected from the network, the level of the control pin is the first level, that is, the first card slot module 15 is in a power-on state, the electronic device 1 accesses to the operator network through the SIM card installed in the first card slot module 15, and when the disconnection time exceeds the second preset time after the electronic device 1 is disconnected from the network, the control module 102 switches the level of the control pin from the first level to the second level, that is, powers down the first card slot module 15, powers up the second card slot module 16, and the electronic device 1 attempts to access to the operator network through the SIM card installed in the second card slot module 16.
In an embodiment, if the electronic device 1 is disconnected from the network, the level of the control pin is the second level, that is, the second card slot module 16 is in a power-on state, the electronic device 1 accesses to the operator network through the SIM card installed in the second card slot module 16, and when the disconnection time exceeds the second preset time after the electronic device 1 is disconnected from the network, the control module 102 switches the level of the control pin from the second level to the first level, that is, the first card slot module 15 is powered on, the second card slot module 16 is powered off, and the electronic device 1 attempts to access to the operator network through the SIM card installed in the first card slot module 15.
In addition, the invention also provides a double-card switching method.

In this embodiment, the execution order of the steps in the flowchart shown in fig. 3 may be changed and some steps may be omitted according to different requirements.
In step S300, when a switching instruction for switching the SIM card is received, the level of the control pin is switched from the first level to the second level.
In an embodiment, the switching instruction for switching the SIM card may be generated by a user performing a SIM switching operation on the electronic apparatus 1, such as clicking a SIM switching icon. The user may also inform the electronic apparatus 1 to perform the SIM card switching operation by an AT (command or other network data instruction) assuming that the level of the control pin is a first level before receiving a switching instruction for switching the SIM card, and switching the level of the control pin from the first level to a second level when receiving the switching instruction for switching the SIM card.

In an embodiment, when the electronic device 1 is in the power-on state, a card slot module needs to be selected for the electronic device 1 first, and the level of the control pin may be set to the first level, so as to power up the first card slot module 15, that is, the first card slot module 15 is used as an initial card slot module. At this time, the first card slot module 15 is in a power-on state, the second card slot module 16 is in a power-off state, and the electronic device 1 accesses the second operator network through the SIM card installed in the first card slot module 15. In other embodiments, when the electronic apparatus 1 is in the power-on state, the level of the control pin may also be set to the second level, so as to power on the second card slot module 16, that is, the second card slot module 16 is used as an initial card slot module, and the electronic apparatus 1 accesses the second operator network through the SIM card installed in the second card slot module 16.
Step S402, determine whether the SIM card is detected within a first preset time after the first card slot module 15 is powered on.
In an embodiment, after the electronic device 1 is powered on and the first card slot module 15 is powered on, it may be determined whether the SIM card is detected within a first preset time after the first card slot module 15 is powered on. If the SIM card is detected within the first preset time, it indicates that the electronic apparatus 1 can access the carrier network through the SIM card installed in the first card-slot module 15. If the SIM card is not detected within the first preset time, it indicates that the first card slot module 15 may not have the SIM card installed or cannot read the SIM card installed in the first card slot module 15, and at this time, a card slot module switching operation needs to be performed, so that the electronic device 1 may attempt to access the operator network through the SIM card installed in the second card slot module 16. The first preset time may be set according to an actual requirement, for example, the first preset time is 10 seconds.
Step S404, if the SIM card is not detected within the first preset time, switching the level of the control pin from a first level to a second level. Otherwise, the control pin is not switched in level.

Fig. 5 is a schematic diagram illustrating an implementation flow of the dual card switching method according to an embodiment of the present invention. In this embodiment, the execution order of the steps in the flowchart shown in fig. 5 may be changed and some steps may be omitted according to different requirements.

For example, the first card slot module 15 is configured to install a SIM card of a first operator, the second card slot module 16 is configured to install a SIM card of a second operator, and at a certain location, there may be no signal from the first operator and a signal from the second operator, and at this time, if the electronic device 1 selects the SIM card of the first operator to access the operator network, a network disconnection situation may occur, and the electronic device 1 may attempt to select the SIM card of the second operator to access the operator network.
