Based on the above-described mobile terminal hardware structure and communication system, various embodiments of the method for multiplexing the USB interface of the mobile terminal and the mobile terminal processor of the present invention are proposed.

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

In the first embodiment of the mobile terminal of the present invention, the mobile terminal is applied to multi-channel communication, When the embodiment of 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 user identification card in the embodiment of the present invention uses the SIM card as an explanation, so that two SIM cards can be implemented. At the same time, dual 4G or dual wifi data communication is used instead of one SIM card in the prior art using 4G communication, and the other SIM card can only use 3G or 2G communication.

The mobile terminal of the embodiment of the present invention includes:

The first processor 200, the second processor 210, the control module 220, and the USB external port 230, wherein the USB external port 230 includes a first way interface 231 and a second way interface 232. In this embodiment, the first processor 200 is connected to the second processor 210, the control module 220, and the first interface 231, and the second processor 210 is also connected to the second interface 232. In a specific implementation, the core idea of the embodiment of the present invention may be connected by other means.

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

The USB external port 230 in this embodiment 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 the same type of processor as the first processor 200, or may be a processor with a relatively weak processing capability relative to the first processor 200. In this embodiment, the second processor 210 uses a relative cost. The first processor 200 has a processor with weak processing capability, the second processor 210 has only data receiving and transmitting functions, and the received data is sent to the first processor 200 for processing.

The control module 220 detects, in real time, whether the mobile terminal is connected to the upper computer through the USB external port 230 through the USB external port 230. The upper computer includes an electronic device such as a computer or a television that can externally connect other devices through the USB, and the mobile terminal is connected to the mobile terminal. In the case of the upper computer, the mobile terminal can be regarded as a slave device of the upper computer, except for the case where only the mobile terminal is charged when connected.

When it is detected that the mobile terminal is connected to the upper computer through the USB external port 230, it is determined The mobile terminal is connected to the upper computer through the first interface 231 or the second interface 232. It should be noted that, in this embodiment, the first path interface 231 is generally configured to perform an operation of viewing and copying part of the content of the mobile terminal by using a host computer when the user externally connects the mobile terminal to the upper computer. The interface used when connecting the mobile terminal to the upper computer is the first interface 231. The second interface 232 is typically an interface that a technician uses when debugging functions such as the second processor 210. Of course, the user can also use the first interface 231 for debugging and other functions.

The control module 220 is further configured to connect the USB interface in the first processor 200 to the first interface 231 when the mobile terminal is connected to the upper computer through the first 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 interface 231, the control module 220 connects the USB interface in the first processor 200 to the first path interface 231, thereby The mobile terminal is connected to the upper computer.

Specifically, it is convenient for the user to set up flexibly, so that it is convenient to use. As shown in FIG. 3, the control module 220 includes:

The receiving unit 221 is configured to receive a user-triggered switching command when the mobile terminal connects to the upper computer through the first path interface.

When the mobile terminal connects to the upper computer through the first path interface, the display may be prompted on the display interface of the upper computer or the mobile terminal, for example, detecting whether the mobile terminal is connected to the upper computer and whether to perform switching. Of course, it is also possible to display application scenarios, such as charging only, data transmission with the host computer, and the like. The user may select a corresponding option on the display interface of the upper computer or the mobile terminal, so as to generate or not generate a handover command, for example, when the user selects the handover, a handover command is generated, otherwise the handover command is not generated; or the user selects only the handover command. When charging, No switching command is generated, otherwise a switching command is generated.

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

Receiving, by the mobile terminal, the switching command triggered by the user, connecting the USB interface in the first processor 200 to the first interface 231, otherwise not connecting the USB interface in the first processor to the The first interface is described.

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 process 210, which requires special explanation. The data communication referred to herein refers to communication through the USB data transmission channel of the first processor 200, and the first processor 200 and the second processing 210 do not communicate through a universal serial port. The serial channel is configured to transmit status information to the first processor 200 by the second process 210. Performing data communication between the first processor 200 and the second processor 210 includes: the first processor 200 transmitting data to the second processor 210, or the second processor 210 transmitting the data to the first processor 200 data. 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 interface 232, the USB interface that controls the first processor 200 is not connected to the first interface 231, nor 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, it needs a specific voltage, and the voltage is greater than the second. The voltage of the processor 210 when it is operated alone, specifically, when the voltage of the second processor 210 is connected to the second processor 210 when the USB interface of the first processor 200 is connected to the second processor 210 in this embodiment. The voltage is increased by 5V.

Those skilled in the art can know that the core idea of the embodiment of the present invention is to use according to the user. In the case of the mobile terminal, the connection state of the USB interface of the first process in the mobile terminal is switched, and the above situation may be determined in any order, that is, whether data communication between the first processor 200 and the second process 210 is performed. It can also be performed before detecting whether the mobile terminal is connected to the upper computer through the USB external port 230, or simultaneously.

In the specific implementation, to ensure the normal operation of the voice service, the priority of the voice service may be set to be higher than the priority of the data service by setting a priority. In addition, during the actual use, when the 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, specifically, every 28 seconds. Is the connected SIM card in place? After confirming whether the connected SIM card is in place, the corresponding SIM card will switch back to the corresponding processor. Because the USB connection state switching time is in milliseconds, and the time for reading the card to confirm whether it is in place is also in milliseconds. Therefore, setting the priority mode can ensure the normal operation of the voice service, and the switching of the SIM card does not affect the normal. Business 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 embodiment of the present invention connects the mobile terminal in a different location of the USB interface of the first processor 100. The first processor 200 sets different states, specifically:

When it is detected that 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 interface 231 or the second interface 232. It should be noted that, in this embodiment, the first path interface 231 is generally configured to perform an operation of viewing and copying part of the content of the mobile terminal by using a host computer when the user externally connects the mobile terminal to the upper computer. The interface used when connecting the mobile terminal to the upper computer is the first interface 231. The second interface 232 is typically an interface that a technician uses when debugging functions such as the second processor 210. Of course, the user can also use the first interface 231 for debugging and other functions.

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 interface 131, so that the first processor is in the first processor a USB interface is connected to the first 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 a second state, Enabling a USB interface in the first processor 200 to be connected to the second processor 210; or connecting the upper computer or the first processor 200 to the mobile terminal without using the first path interface 231 When the second processor 210 does not perform data communication, the first electronic switch S1 is controlled 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 interface 232, so that the second processor 210 is The upper computer is connected, and the first electronic switch S1 is controlled to be in a third state by the control module 220.

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

Specifically, it is convenient for the user to set up flexibly, so that it is convenient to use. The control module 220 includes:

When the mobile terminal connects to the upper computer through the first path interface, the display may be prompted on the display interface of the upper computer or the mobile terminal, for example, detecting whether the mobile terminal is connected to the upper computer and whether to perform switching. Of course, it is also possible to display application scenarios, such as charging only, data transmission with the host computer, and the like. The user may select a corresponding option on the display interface of the upper computer or the mobile terminal, so as to generate or not generate a switching command, for example, when the user selects the switching, a switching command is generated, otherwise the user does not switch; or the user selects only charging. , does not generate a switch command, otherwise a switch command is generated.

The mobile terminal receives the switching command triggered by the user, and controls the first electronic switch S1 to be in the first state. In this embodiment, the first state is that the first electronic switch S1 is closed to one end of the first interface 231, thereby The USB interface in the first processor 200 is connected to the first path interface 231, otherwise no handover is performed. Of course, the first electronic switch S1 can 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 process 210, which requires special explanation. The data communication referred to herein refers to communication through the USB data transmission channel of the first processor 200, not the first processor 200 and the second The processes 210 communicate via a universal serial port that is configured to transmit status information to the first processor 200 by the second process 210. Performing data communication between the first processor 200 and the second processor 210 includes: the first processor 200 transmitting data to the second processor 210, or the second processor 210 transmitting the data to the first processor 200 data. 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 performed between the first processor 200 and the second process 210, the first electronic switch S1 is in the second state, and in the embodiment, the first electronic switch S1 is closed to the second state. One end of the processor 210 is such that a USB interface in the first processor 200 is connected to the second processor 210. Controlling the first electronic switch to be in a third state when the mobile terminal is not connected to the upper computer through a first path interface or when data communication is not performed between the first processor and the second processor In this embodiment, the third state is suspended, that is, not closed.

The slave device power supply module 240 is configured to provide a preset voltage for the second processor 210 when performing data communication between the first processor 200 and the second processor 210; or When the two-way interface 232 is connected to the upper computer, a preset voltage is provided for the second 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 the data sent by the first processor 200, it needs a specific voltage, and the voltage is greater than the second. The voltage of the processor 210 when it is operated alone. Specifically, when the USB interface of the first processor 200 is connected to the second processor 210 in this embodiment, the slave power supply module 240 is controlled to provide the second processor 210 with a preset. Set the voltage, the preset voltage can be set according to the actual situation, for example, the preset voltage is 5V; meanwhile, due to the USB external port 230 When the second interface 232 is normally used, an additional voltage is required to operate normally. When the mobile terminal connects the upper computer through the second interface 232, the preset voltage is provided for the second interface 232.

A person skilled in the art can understand that the core idea of the embodiment of the present invention is to switch the connection state of the first processed USB interface in the mobile terminal according to the situation in which the user uses the mobile terminal, and the foregoing may be determined in any order, that is, Whether data communication is performed between the first processor 200 and the second process 210 may also be performed before detecting whether the mobile terminal is connected to the upper computer through the USB external port 230, or simultaneously.

In the specific implementation, to ensure the normal operation of the voice service, the priority of the voice service may be set to be higher than the priority of the data service by setting a priority. In addition, due to the actual use, after the user equipment is turned on, the user equipment and the data card communicate once every 28 seconds to confirm whether the data card is in place to ensure normal communication. The 28 second communication is controlled by the processing chip connected to the data card. For example, the processing chip sends a blank data to the data card. If the 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 a preset time interval for in-place confirmation of the data card;

If the first SIM card 250 is in-position confirmed (the default 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 The modem module 201 is further configured to issue a first control command to control the logic switch 1 to turn on the connection path of the first SIM card 250 and the first modem module 201.

If the second SIM card 260 is in-position confirmed (the default 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 The modem module 201 is further configured to issue a second control command to control the logic switch 2 to conduct a connection path between the second SIM card 260 and the first processing chip.

Similarly, the second modem module 221 is further configured to forward to the first SIM at preset time intervals. Card 250 or second SIM card 260 sends information for in-place confirmation of the data card;

If the first SIM card 250 is in-position confirmed (the default 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 The modem module 201 is further configured to issue a first control command to control the logic switch 1 to turn on the connection path of the first SIM card 250 and the second modem module 221.

If the second SIM card 260 is in-position confirmed (the default 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 The modem module 201 is further configured to issue a second control command to control the logic switch 2 to turn on the connection path of 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 be connected to the first modem module 201 (for example, switching to the first modem module 201 for PS data service), Every 28 seconds, it is required to switch back to the second modem module 221, that is, to connect to the second modem module 221 through the control logic switch 2, to complete the confirmation of the data card in place, after the card confirmation is completed, the second The SIM card 260 is switched back to the first processing chip again to ensure normal communication. And so on, if the first SIM card 250 originally connected to the first processing chip is switched and connected to the second modem module 221, it needs to switch back to the first processing chip every 28 seconds, that is, by controlling the logic switch 1 Connected to the first modem module 201 to complete the confirmation of the data card in place. After the card confirmation is completed, the first SIM card 250 is switched back to the second modem module 221 again to ensure normal communication.

The switching time of the logic switch is in the order of milliseconds, and the time for reading the card to confirm whether the bit is in place is also millisecond. Therefore, the switching of the data card does not affect the normal service transmission.

By setting the priority, the priority of the voice service is set to be higher than the priority of the data service, so that the voice service can be preferentially guaranteed during the process of confirming the data card.

According to the in-position acknowledgment mechanism described above, the first SIM card 250 and the second modem module 221 When the connection is for data service transmission, the first SIM card 250 can 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 the bit is confirmed.

According to the in-position acknowledgment mechanism described above, 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 the bit is confirmed.

According to the in-position acknowledgment 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 also connected to the second modem module 221 for data service transmission. . It is only necessary to ensure that the first SIM card 250 and the second SIM card 260 are in place when the bit is confirmed.

According to the in-position acknowledgment 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. . It is only necessary to ensure that the first SIM card 250 and the second SIM card 260 are in place when the bit is confirmed.

Because the mobile terminal can perform different tasks when the USB interface of the first processor 200 is connected to different locations, for example, in the embodiment, when the mobile terminal is a slave device of the upper computer, The USB interface of the first processor 200 of the mobile terminal is connected to the host computer, and cannot perform data communication with the second processor 210. In order to avoid the conflict in use, the mobile terminal cannot be used normally. This embodiment will be in the first processor. The USB interface of 100 is connected to different locations, and the first processor 200 of the mobile terminal is set to a different state. Specifically, the first processor 200 is configured to connect the upper terminal to the mobile terminal through the first interface 231. Switching the state of the first processor 200 to the slave device state; or, when performing data communication between the first processor 200 and the second processor 210, the first process The state of the device 200 is switched to the master device state; or, the mobile terminal is not connected to the host computer through the first path interface 231 or is not performed between the first processor 200 and the second processor 210 At the time of data communication, the state of the first processor 200 is switched to null.

Except when charging the mobile terminal only when connected.

When it is detected that 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 interface 231 or the second interface 232. It should be noted that the first path interface 231 in this embodiment is generally configured as a user. When the mobile terminal is externally connected to the upper computer, the operation of viewing and copying part of the content of the mobile terminal by the upper computer can be performed. Generally, the interface used by the user to connect the mobile terminal to the upper computer is the first interface 231. The second interface 232 is typically an interface that a technician uses when debugging functions such as the second processor 210.
