Based on the hardware structure of the mobile terminal and the internal frame diagram, the mobile terminal and the upgrading method of the invention are provided.
Referring to fig. 2, fig. 2 is a schematic structural diagram of a mobile terminal in an embodiment of the present invention. The mobile terminal includes a first Modem 200(Modem1), a second Modem 210(Modem2), a Wifi module 230, a first logic switch 270, a second logic switch 280, a first SIM card 250, and a second SIM card 260, where the first Modem 200 and the second Modem 210 may be, for example, 180 in fig. 1, and may respectively run with corresponding applications ap, and of course, the first Modem 200 is further connected to a first radio frequency (not shown), and the second Modem 210 is further connected to the first radio frequency (not shown).
The first modem 200 is further configured to output a first preset voltage to control the first logic switch 270 to be in a first state when the user uses the first SIM card 250 for voice communication, so that the first SIM card 250 is connected to the first modem 200; 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 a second state, so that the second SIM card 260 is connected to the first modem 200.
In the present embodiment, when the user performs voice communication using the first SIM card 250, the first modem 200 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 202; and outputs a low level, the first SIM card 250 is connected to the second modem 210. Or when outputting high level, the second logic switch 280 is turned on, so that the second SIM card 260 is connected to the first modem 202; and outputs a low level, the second SIM card 260 is connected to the second modem 210.
In the first embodiment of the present invention, if the first SIM card 250 is connected to the first modem 202, 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 202. Thus, the first SIM card 250 can perform CS voice and PS data services through the first network.
Likewise, if the second SIM card 260 is connected with the first modem 200, the second SIM card 260 may reside in the PS domain and the CS domain of the first network through the first modem 200. 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 210, the first SIM card 250 may reside in the PS domain of the second network through the second modem 210. 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 210, the second SIM card 260 may reside in the PS domain of the second network through the second modem 210. 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 200 supports PS data service and CS voice service, and the second modem 210 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 210 has the CS voice service, the first modem 200 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 200 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 ap 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 200 outputs a first control command to control the first logic switch 270 so that the first SIM card 250 is connected to the first modem 200.

If the connection channel between the second SIM card 260 and the second modem 210 is turned on, the transmission flow of the PS data service is: the application ap receives the data and transmits it to the second modem 210; the second radio frequency transmits the uplink signal processed by the second modem 210 to the second network (4G network), receives the downlink signal from the second network (4G network), and transmits the downlink signal to the second modem 210 for processing; the application ap outputs the downstream signal processed by the second modem 210.
When the first electronic switch is in the first state, the mobile terminal disconnects the data communication between the first modem and the second process.
The first modem 200 may be the controller 180 of fig. 1. The second modem 210 may use the same type of modem as the first modem 200, or may use a modem with relatively low processing power compared to the first modem 200, in this embodiment, to save cost, the second modem 210 uses a modem with relatively low processing power compared to the first modem 200, and the second modem 210 only has data receiving and transmitting functions, and the received data is transmitted to the first modem 200 for processing.

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.
According to the above-mentioned on-site confirmation mechanism, when the first SIM card 250 is connected to the second modem 210 for data service transmission, the first SIM card 250 can also be connected to the first modem 200 for voice transmission at the same time. It is only necessary to ensure that the first SIM card 250 is in place when confirming in place.
According to the above-mentioned on-site confirmation mechanism, when the second SIM card 260 is connected to the second modem 210 for data service transmission, the second SIM card 260 is also connected to the first modem 200 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-mentioned on-site confirmation mechanism, when the first SIM card 250 is connected to the first modem 200 for data service transmission and voice service, the second SIM card 260 is also connected to the second modem 210 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-mentioned on-site confirmation mechanism, when the second SIM card 260 is connected to the first modem 200 for data service transmission and voice service, the first SIM card 250 is also connected to the second modem 210 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.
