For example, the external device may include a wired or wireless headset port, an external power supply (or battery charger) port, a wired or wireless data port, a memory card port, a port for connecting a device having an identification module, an audio input/output (I/O) port, a video I/O port, an earphone port, and the like. The identification module may store various information for authenticating a user using the mobile terminal 100 and may include a User Identity Module (UIM), a Subscriber Identity Module (SIM), a Universal Subscriber Identity Module (USIM), and the like. In addition, a device having an identification module (hereinafter, referred to as an "identification device") may take the form of a smart card, and thus, the identification device may be connected with the mobile terminal 100 via a port or other connection means. The interface unit 170 may be used to receive input (e.g., data information, power, etc.) from an external device and transmit the received input to one or more elements within the mobile terminal 100 or may be used to transmit data between the mobile terminal and the external device.

In addition, when the mobile terminal 100 is connected with an external cradle, the interface unit 170 may serve as a path through which power is supplied from the cradle to the mobile terminal 100 or may serve as a path through which various command signals input from the cradle are transmitted to the mobile terminal. Various command signals or power input from the cradle may be used as signals for recognizing whether the mobile terminal is accurately mounted on the cradle. The output unit 150 is configured to provide output signals (e.g., audio signals, video signals, alarm signals, vibration signals, etc.) in a visual, audio, and/or tactile manner. The output unit 150 may include a display unit 151, an audio output module 152, and the like.

The display unit 151 may display information processed in the mobile terminal 100.

Depending on the particular desired implementation, the mobile terminal 100 may include two or more display units (or other display devices), for example, the mobile terminal may include an external display unit (not shown) and an internal display unit (not shown). The touch screen may be used to detect a touch input pressure as well as a touch input position and a touch input area.

The audio output module 152 may convert audio data received by the wireless communication unit 110 or stored in the memory 160 into an audio signal and output as sound when the mobile terminal is in a call signal reception mode, a call mode, a recording mode, a voice recognition mode, a broadcast reception mode, or the like.

Hereinafter, a slide-type mobile terminal among various types of mobile terminals, such as a folder-type, bar-type, swing-type, slide-type mobile terminal, and the like, will be described as an example for the sake of brevity. Accordingly, the present invention can be applied to any type of mobile terminal, and is not limited to a slide type mobile terminal.

The mobile terminal 100 as shown in fig. 1 may be configured to operate with communication systems such as wired and wireless communication systems and satellite-based communication systems that transmit data via frames or packets.

Based on the above mobile terminal hardware structure and communication system, the present invention provides various embodiments of the method for multiplexing USB interfaces of the mobile terminal and the mobile terminal processor.

Referring to fig. 2, fig. 2 is a schematic structural diagram of a mobile terminal according to a first embodiment of the present invention.

In the first embodiment of the mobile terminal of the present invention, the mobile terminal is applied to multi-channel communication, and when the present invention is applied to multi-channel communication, since the first processor 100 in the mobile terminal has only one USB interface, it should be understood that the SIM card in the embodiment of the present invention is used as an explanation, in order to implement that two SIM cards can simultaneously use dual 4G or dual wifi data communication, instead of one SIM card using 4G communication and the other SIM card using only 3G or 2G communication in the prior art.

The mobile terminal of the present invention comprises:

the system comprises a first processor 200, a second processor 210, a control module 220 and a USB external port 230, wherein the USB external port 230 comprises a first road interface 231 and a second road interface 232. In this embodiment, the first processor 200 is respectively connected to the second processor 210, the control module 220, and the first way interface 231, and the second processor 210 is further connected to the second way interface 232. The specific implementation can be connected through other modes according to the core idea of the invention.

The control module 220 is configured to determine whether the mobile terminal is connected to the upper computer through the first road interface 231 or the second road interface 232 when detecting that the mobile terminal is connected to the upper computer.

In this embodiment, the USB external port 230 may be the interface unit 170 in fig. 1, and the first processor 200 may be the controller 180 in fig. 1. The second processor 210 may use a processor of the same type as the first processor 200, or may use a processor with relatively weak processing capability with respect to the first processor 200, in this embodiment, to save cost, the second processor 210 uses a processor with relatively weak processing capability with respect to the first processor 200, and the second processor 210 only has data receiving and transmitting functions, and transmits received data to the first processor 200 for processing.

Control module 220 detects through USB external port 230 in real time whether mobile terminal connects to the host computer through USB external port 230, the host computer includes electronic equipment that can pass through USB external other equipment such as computer, TV, mobile terminal is connected to during the host computer, this mobile terminal can regard as the slave unit of host computer, only right during the connection the mobile terminal charges except.

When the mobile terminal is connected to the upper computer through the USB external port 230, it is determined whether the mobile terminal is connected to the upper computer through the first path interface 231 or the second path interface 232. It should be noted that in this embodiment, the first path interface 231 is generally used for performing an operation of viewing and copying a part of contents of the mobile terminal through the upper computer when the user connects the mobile terminal to the upper computer, and an interface used when the user connects the mobile terminal to the upper computer is the first path interface 231. Second way interface 232 is typically an interface that a technician would use to debug the functionality of second processor 210, etc. Of course, the user may also use the first channel interface 231 to perform debugging and other functions.

The control module 220 is further configured to connect the USB interface in the first processor 200 to the first channel interface 231 when the mobile terminal is connected to the upper computer through the first channel interface 231; or when data communication is performed between the first processor 200 and the second processor 210, the USB interface in the first processor 200 is connected to the second processor 210.

When the control module 220 determines that the mobile terminal is connected to the upper computer through the first path of interface 231, the control module 220 connects the USB interface in the first processor 200 to the first path of interface 231, so that the mobile terminal is connected to the upper computer.

Particularly, the device is flexible for users to set, thereby being convenient to use. As shown in fig. 3, the control module 220 includes:

the receiving unit 221 is configured to receive a switching command triggered by a user when the mobile terminal is connected to the upper computer through the first path of interface.

When the mobile terminal is connected with the upper computer through the first path of interface, the upper computer or a display interface of the mobile terminal can be prompted, for example, whether the mobile terminal is connected with the upper computer or not is detected to be switched. Of course, application scenarios, such as charging only, data transmission with an upper computer, and the like, may also be displayed. A user can select corresponding options on a display interface of the upper computer or the mobile terminal, so that a switching command is generated or not generated, for example, when the user selects switching, the switching command is generated, otherwise, the switching command is not generated; or when the user selects to only charge, the switching command is not generated, otherwise, the switching command is generated.

A switching unit 222, configured to connect the USB interface in the first processor to the first path interface according to the switching command.

The mobile terminal receives the switching command triggered by the user, connects the USB interface in the first processor 200 to the first path interface 231, otherwise does not connect the USB interface in the first processor to the first path interface.

If the control module 220 does not detect that the mobile terminal is connected to the upper computer through the first path interface 231, it is determined whether data communication is performed between the first processor 200 and the second processor 210, and it should be specifically noted that the data communication described herein refers to communication performed through a USB data transmission channel of the first processor 200, and is not communication performed through a universal serial port channel between the first processor 200 and the second processor 210, where the universal serial port channel is used for the second processor 210 to send status information to the first processor 200. Communicating data between the first processor 200 and the second processor 210 includes: the first processor 200 sends data to the second processor 210 or the second processor 210 sends data to the first processor 200. If data communication is performed between the first processor 200 and the second processor 210, the USB interface in the first processor 200 is connected to the second processor 210.

If it is detected that the mobile terminal is connected to the upper computer through the second road interface 232, the USB interface controlling the first processor 200 is not connected to the first road interface 231, nor connected to the second processor 210.

When the USB interface of the first processor 200 is connected to the second processor 210, in order to enable the second processor 210 to normally receive the data sent by the first processor 200, a specific voltage is required, where the voltage is greater than the voltage when the second processor 210 operates alone, specifically, in this embodiment, the voltage of the second processor 210 is 5V added to the voltage when the USB interface of the first processor 200 is connected to the second processor 210.

Those skilled in the art will recognize that: the core idea of the present invention is to switch the connection state of the USB interface of the first process in the mobile terminal according to the situation of using the mobile terminal by the user, and the above situations may not be in sequence, that is, it is determined whether to perform data communication between the first processor 200 and the second process 210, or before or simultaneously detecting whether the mobile terminal is connected to the upper computer through the USB external port 230.

In order to ensure normal operation of voice service in specific implementation, priority of voice service may be set to be higher than priority of data service by setting priority. In addition, in the actual use process, when two SIM cards are connected, the first processor 200 and the second processor 210 confirm whether the connected SIM card is in place at regular intervals, and specifically, confirm whether the connected SIM card is in place at intervals of 28 seconds. After confirming whether the connected SIM card is in place, the corresponding SIM card is switched back to the corresponding processor. Because the USB connection state is switched by millisecond and the card reading confirms whether the current use is also millisecond, the priority mode can preferentially ensure the normal operation of the voice service and the SIM card switching can not influence the normal service transmission.

Further, in order to facilitate the mobile terminal to perform corresponding activities when the USB interface of the first processor 200 is connected to different locations, the present invention sets the first processor 200 in the mobile terminal to different states at the locations where the USB interface of the first processor 100 is connected to different locations, specifically:

the first processor 200 is configured to switch a state of the first processor 200 into a slave device state when the mobile terminal is connected to the upper computer through the first path interface 231; or, when data communication is performed between the first processor 200 and the second processor 210, the state of the first processor 200 is switched to a master device state; or, when the mobile terminal is not connected to the upper computer through the first path interface 231 or data communication is not performed between the first processor 200 and the second processor 210, the state of the first processor 200 is switched to null.

Because the mobile terminal can perform different tasks when the USB interface of the first processor 200 is connected to different locations, for example, when the mobile terminal is used as a slave device of an upper computer in this embodiment, the USB interface of the first processor 200 of the mobile terminal is connected to the upper computer, and cannot perform data communication with the second processor 210, in order to avoid conflict generated during use and make the mobile terminal unable to be used normally, this embodiment will set the first processor 200 in the mobile terminal to different states at different locations where the USB interface of the first processor 100 is connected: the first processor 200 is configured to switch a state of the first processor 200 into a slave device state when the mobile terminal is connected to the upper computer through the first path interface 231; or, when data communication is performed between the first processor 200 and the second processor 210, the state of the first processor 200 is switched to a master device state; or, when the mobile terminal is not connected to the upper computer through the first path interface 231 or data communication is not performed between the first processor 200 and the second processor 210, the state of the first processor 200 is switched to null.

Referring to fig. 3, fig. 3 is a schematic structural diagram of a mobile terminal according to a second embodiment of the present invention.

In this embodiment, the mobile terminal is applied to multi-channel communication, and when the invention is applied to multi-channel communication, because the first processor 100 in the mobile terminal has only one USB interface, in order to implement that two SIM cards can simultaneously use dual 4G or dual wifi data communication, instead of using 4G communication for one SIM card and only 3G or 2G communication for the other SIM card in the prior art. The mobile terminal in this embodiment includes:

the system comprises a first processor 200, a second processor 210, a control module 220, a USB external port 230, a first electronic switch S1, a second electronic switch S2, and a slave device power supply module 240, wherein the USB external port 230 comprises a first road interface 231 and a second road interface 232.

In this embodiment, the first electronic switch S1 is respectively connected to the first processor 200, the second processor 210, the control module 220, and the first way interface 231, the first processor 200 is further respectively connected to the control module 220, the slave device power supply module 240, the second electronic switch S2, and the second way interface 232, and the second processor 210 is further respectively connected to the second electronic switch S2, and the second way interface 232. The specific implementation can be connected through other modes according to the core idea of the invention.

Specifically, referring to fig. 5, the first processor 200 in the mobile terminal for multi-channel communication may include: the second processor 210 may include, in the application processing module 202 and the first modem module 201: a second modem module 221, wherein the mobile terminal further includes: the first SIM card 250, the second SIM card 260, the first logic switch 270, the second logic switch 280, the first radio frequency connected to the first modem module 201, and the second radio frequency connected to the second modem module 221. The first modem module 201 and the second modem module 221 may correspond to the mobile communication module 112 in fig. 1.

The first processor 200 is further configured to output a first preset voltage to control the first logic switch 270 to be in a fourth state when a user uses the first SIM card 250 for voice communication, so that the first SIM card 250 is connected to the first modem module 201; or when the user uses the second SIM card 260 for voice communication, a second preset voltage is output to control the second logic switch 280 to be in the fifth state, so that the second SIM card 260 is connected to the first modem module 201.

In this embodiment, when the user uses the first SIM card 250 for voice communication, the first modem module 201 controls the first logic switch 270 and the second logic switch 280 by outputting a high/low level. For example, when outputting a high level, the first logic switch 270 is turned on, so that the first SIM card 250 is connected to the first modem module 201; and when the output level is low, the first SIM card 250 is connected to the second modem module 221. Or when outputting a high level, the second logic switch 280 is turned on, so that the second SIM card 260 is connected to the first modem module 201; and when the output level is low, the second SIM card 260 is connected to the second modem module 221.

In the first embodiment of the present invention, if the first SIM card 250 is connected to the first modem module 201, the first SIM card 250 may reside in a PS (packet switching) domain and a CS (circuit switching) domain of the first network through the first modem module 201. Thus, the first SIM card 250 can perform CS voice and PS data services through the first network.

Similarly, if the second SIM card 260 is connected to the first modem module 201, the second SIM card 260 may reside in the PS domain and the CS domain of the first network through the first modem module 201. Thus, the second SIM card 260 can perform CS voice and PS data services through the first network.

If the first SIM card 250 establishes a connection with the second modem module 221, the first SIM card 250 may reside in the PS domain of the second network through the second modem module 221. Thus, the first SIM card 250 can perform PS data service through the second network.

Similarly, if the second SIM card 260 establishes a connection with the second modem module 221, the second SIM card 260 may reside in the PS domain of the second network through the second modem module 221. Thus, the second SIM card 260 can perform PS data services through the second network.

The first network and the second network may be different networks of different operators, or may be different or the same network of the same operator. The first network and the second network may both be 4G networks (e.g., 4G networks such as LTE networks).

The first modem module 201 supports PS data service and CS voice service, and the second modem module 221 supports only PS data service. When the data card (the first SIM card 250 or the second SIM card 260) connected to the second modem module 221 has the CS voice service, the first modem module 201 controls the logic switch (the first logic switch 270 or the second logic switch 280) so that the corresponding data card is connected to the first modem module 201 to implement the CS voice service.

It should be understood that if it is a PS voice service, it is transmitted according to the transmission of a PS data service. The application processing module 202 receives an operation instruction of the user, and if the operation instruction is to perform a CS voice service through the first SIM card 250: the first modem module 201 outputs a first control command to control the first and second logic switches 28070 so that the first SIM card 250 is connected to the first modem module 201. The process of performing the CS voice service through the first SIM card 250 includes:

After the voice communication connection is established, the voice uplink transmission process is as follows: the microphone collects voice signals, and the coder-decoder receives the collected voice signals, performs analog-to-digital conversion on the voice signals and transmits the voice signals to the digital signal processing chip; the digital signal processing chip performs audio processing on the received signal and transmits the processed signal to the first modulation and demodulation module 201; the first radio frequency transmits the signal processed by the first modem module 201. The voice downlink transmission process comprises the following steps: the first radio frequency receives the downlink signal and transmits the downlink signal to the first modem module 201; the digital signal processing chip (ADSP) performs audio processing on the signal processed by the first modem module 201 and transmits the signal to a coder-decoder (codec); the coder-decoder performs analog-to-digital conversion on the received signal and then transmits the signal to the receiver.

The process of performing the CS voice service through the second SIM card 260 includes:

The application processing module receives an operation instruction of a user, and if the operation instruction is to perform a PS data service through the first SIM card 250, the first modem module 201 outputs a first control instruction to control the first logic switch 270 to conduct a connection channel between the first SIM card 250 and the first modem module 201, and also outputs a second control instruction to control the first logic switch 270 to conduct a connection channel between the first SIM card 250 and the second modem module 221, which can both implement transmission of the PS data service.

Specifically, if the connection channel between the first SIM card 250 and the first modem module 201 is conducted, the transmission flow of the PS data service is as follows: the application processing module receives data and transmits the data to the first modulation and demodulation module 201; the first radio frequency transmits the uplink signal processed by the first modem module 201 to the first network (4G network), receives the downlink signal from the first network (4G network), and transmits the downlink signal to the first modem module 201 for processing; the application processing module outputs the downlink signal processed by the first modem module 201.

If the connection channel between the first SIM card 250 and the second modem module 221 is conducted, the transmission flow of the PS data service is as follows: the application processing module receives the data and transmits the data to the second modem module 221; the radio frequency 2 transmits the uplink signal processed by the second modem module 221 to the LTE network, receives the downlink signal from the LTE network, and transmits the downlink signal to the second modem module 221 for processing; the application processing module outputs the downlink signal processed by the second modem module 221.

If the operation instruction is to perform the PS data service through the second SIM card 260, the first modem module 201 may output a first control instruction to control the second logic switch 280 to conduct the connection channel between the second SIM card 260 and the first modem module 201, and may also output a second control instruction to control the second logic switch 280 to conduct the connection channel between the second SIM card 260 and the second modem module 221, which may both implement the transmission of the PS data service.

Specifically, if the connection channel between the second SIM card 260 and the first modem module 201 is conducted, the transmission flow of the PS data service is as follows: the application processing module receives data and transmits the data to the first modulation and demodulation module 201; the first radio frequency transmits the uplink signal processed by the first modem module 201 to the first network (4G network), receives the downlink signal from the first network (4G network), and transmits the downlink signal to the first modem module 201 for processing; the application processing module outputs the downlink signal processed by the first modem module 201.

If the connection channel between the second SIM card 260 and the second modem module 221 is conducted, the transmission flow of the PS data service is as follows: the application processing module receives the data and transmits the data to the second modem module 221; the radio frequency 2 transmits the uplink signal processed by the second modem module 221 to a second network (4G network), receives a downlink signal from the second network (4G network), and transmits the downlink signal to the second modem module 221 for processing; the application processing module outputs the downlink signal processed by the second modem module 221.

The control module 220 is further configured to control the first electronic switch S1 to be in a first state when the mobile terminal is connected to the upper computer through the first channel interface 131, so that the USB interface in the first processor is connected to the first channel interface 231; or when data communication is performed between the first processor 200 and the second processor 210, the first electronic switch S1 is in the second state, so that the USB interface in the first processor 200 is connected to the second processor 210; or when the mobile terminal is not connected to the upper computer through the first path interface 231 or data communication is not performed between the first processor 200 and the second processor 210, controlling the first electronic switch S1 to be in the third state.

The first processor 200 is further configured to control the second electronic switch S2 to be closed when the mobile terminal is connected to the upper computer through the second road interface 232, so that the second processor 210 is connected to the upper computer, and control the first electronic switch S1 to be in a third state through the control module 220.

When the control module 220 determines that the mobile terminal is connected to the upper computer through the first channel interface 231, the control module 220 controls the first electronic switch S1 to be in a first state, in this embodiment, the first state is that the first electronic switch S1 is closed to one end of the first channel interface 231, and the USB interface in the first processor 200 is connected to the first channel interface 231, so that the mobile terminal is connected to the upper computer.

Particularly, the device is flexible for users to set, thereby being convenient to use. The control module 220 includes:

When the mobile terminal is connected with the upper computer through the first path of interface, the upper computer or a display interface of the mobile terminal can be prompted, for example, whether the mobile terminal is connected with the upper computer or not is detected to be switched. Of course, application scenarios, such as charging only, data transmission with an upper computer, and the like, may also be displayed. A user can select corresponding options on a display interface of the upper computer or the mobile terminal, so that a switching command is generated or not generated, for example, when the user selects switching, the switching command is generated, otherwise, the switching is not performed; or when the user selects to only charge, the switching command is not generated, otherwise, the switching command is generated.

The mobile terminal receives the switching command triggered by the user, and controls the first electronic switch S1 to be in a first state, in this embodiment, the first state is that the first electronic switch S1 is closed to one end of the first channel interface 231, so as to connect the USB interface in the first processor 200 to the first channel interface 231, otherwise, no switching is performed. Of course, the first electronic switch S1 may also be implemented by software.

If the control module 220 does not detect that the mobile terminal is connected to the upper computer through the first path interface 231, it is determined whether data communication is performed between the first processor 200 and the second processor 210, and it should be specifically noted that the data communication described herein refers to communication performed through a USB data transmission channel of the first processor 200, and is not communication performed through a universal serial port channel between the first processor 200 and the second processor 210, where the universal serial port channel is used for the second processor 210 to send status information to the first processor 200. Communicating data between the first processor 200 and the second processor 210 includes: the first processor 200 sends data to the second processor 210 or the second processor 210 sends data to the first processor 200. If data communication is performed between the first processor 200 and the second processor 210, the USB interface in the first processor 200 is connected to the second processor 210. When the data communication is not performed between the first processor 200 and the second processor 210, the first electronic switch S1 is in the second state, in this embodiment, the first electronic switch S1 is closed to one end of the second processor 210, so that the USB interface in the first processor 200 is connected to the second processor 210. When the mobile terminal is not connected with the upper computer through the first path of interface or data communication is not performed between the first processor and the second processor, the first electronic switch is controlled to be in a third state, and the third state is suspended, namely, is not closed.

A slave device power supply module 240, configured to provide a preset voltage for the second processor 210 when data communication is performed between the first processor 200 and the second processor 210; or when the mobile terminal is connected to the upper computer through the second road interface 232, a preset voltage is provided for the second road interface 232.

When the USB interface of the first processor 200 is connected to the second processor 210, in order to enable the second processor 210 to normally receive data sent by the first processor 200, a specific voltage is required, where the voltage is greater than a voltage when the second processor 210 operates alone, specifically, in this embodiment, when the USB interface of the first processor 200 is connected to the second processor 210, the slave device power supply module 240 is controlled to provide a preset voltage for the second processor 210, where the preset voltage may be set according to an actual situation, for example, the preset voltage is 5V; meanwhile, since the second channel interface 232 of the USB external port 230 can normally operate only by an extra voltage when being used normally, the second channel interface 232 is supplied with the preset voltage when the mobile terminal is connected to the upper computer through the second channel interface 232.

In order to ensure normal operation of voice service in specific implementation, priority of voice service may be set to be higher than priority of data service by setting priority. In addition, in the actual use process, after the user equipment is started, the communication between the user equipment and the data card is carried out once in 28 seconds so as to confirm whether the data card is in place and ensure the normal communication. The one 28 second communication is controlled by a processing chip connected to the data card, for example, the processing chip sends a null data to the data card, if a response is received, the data card is confirmed to be in place, otherwise the data card is not in place.

The first modem module 201 is further configured to send information to the first SIM card 250 or the second SIM card 260 at preset time intervals to perform in-place acknowledgement of the data card;

if the first SIM card 250 is confirmed in place (it is default that the first SIM card 250 should be connected to the first modem module 201), and the first SIM card 250 is not connected to the first modem module 201, the first modem module 201 is further configured to issue a first control instruction to control the logic switch 1 to turn on a connection path between the first SIM card 250 and the first modem module 201.

If the second SIM card 260 is confirmed in place (it is default that the second SIM card 260 should be connected to the first modem module 201), and the second SIM card 260 is not connected to the first modem module 201, the first modem module 201 is further configured to issue a second control instruction to control the logic switch 2 to turn on the connection path between the second SIM card 260 and the first processing chip.

Similarly, the second modem module 221 is further configured to send information to the first SIM card 250 or the second SIM card 260 at preset time intervals to perform on-site confirmation of the data card;

if the first SIM card 250 is confirmed in place (it is default that the first SIM card 250 should be connected to the second modem module 221), and the first SIM card 250 is not connected to the second modem module 221, the first modem module 201 is further configured to issue a first control instruction to control the logic switch 1 to turn on the connection path between the first SIM card 250 and the second modem module 221.

If the second SIM card 260 is confirmed in place (it is default that the first SIM card 250 should be connected to the second modem module 221), and the second SIM card 260 is not connected to the second modem module 221, the first modem module 201 is further configured to issue a second control instruction to control the logic switch 2 to turn on the connection path between the second SIM card 260 and the second modem module 221.

For example, if the second SIM card 260 originally connected to the second modem module 221 is switched to connect to the first modem module 201 (for example, to the first modem module 201 for PS data service), the second modem module 221 needs to be switched back every 28 seconds, that is, the logic switch 2 is controlled to connect to the second modem module 221 to complete the confirmation of the data card being in place, and after the card reading confirmation is completed, the second SIM card 260 is switched back to the first processing chip again to ensure the normal operation of communication. And so on, if the first SIM card 250 originally connected to the first processing chip is switched to the second modem module 221, the first processing chip needs to be switched back every 28 seconds, that is, the first processing chip is connected to the first modem module 201 through the control logic switch 1 to complete the confirmation of the data card being in place, and after the card reading confirmation is completed, the first SIM card 250 is switched back to the second modem module 221 again to ensure the normal operation of communication.

The switching time of the logic switch is millisecond level, and the card reading confirmation is also millisecond level when in-place use is confirmed, so that the normal service transmission is not influenced by the switching of the data card.

The priority of the voice service is set to be higher than that of the data service by setting the priority, so that the normal operation of the voice service can be preferentially ensured in the process of confirming the position of the data card.

According to the above in-place confirmation mechanism, when the first SIM card 250 is connected to the second modem module 221 for data service transmission, the first SIM card 250 may also be connected to the first modem module 201 for voice transmission. It is only necessary to ensure that the first SIM card 250 is in place when confirming in place.

According to the above in-place confirmation mechanism, when the second SIM card 260 is connected to the second modem module 221 for data service transmission, the second SIM card 260 is further connected to the first modem module 201 for voice transmission. It is only necessary to ensure that the second SIM card 260 is in place when confirming in place.

According to the above in-place confirmation mechanism, when the first SIM card 250 is connected to the first modem module 201 for data service transmission and voice service, the second SIM card 260 is further connected to the second modem module 221 for data service transmission. Only when in-place confirmation is needed, the first SIM card 250 and the second SIM card 260 are in place respectively.

According to the above in-place confirmation mechanism, when the second SIM card 260 is connected to the first modem module 201 for data service transmission and voice service, the first SIM card 250 is also connected to the second modem module 221 for data service transmission. Only when in-place confirmation is needed, the first SIM card 250 and the second SIM card 260 are in place respectively.
