[0061] Exemplarily, the first end of the first interface is connected to the mobile broadband device by inserting the mobile broadband device into an M.2 slot, the second end of the first interface is connected to the first end of the first control module by connecting several pins of the first interface to the GPIO port of the first control module, the second end of the first control module is connected to the first end of the first input-output module by connecting an I2C port, a Serial (I2C) port, a Driver (SPI) port, an ADC port, a DAC port and an IRQ port of the first control module to the first input-output module respectively, the second end of the first input-output module is connected to the first end of the first transmission module by connecting the first input-output module to the hardware input / output pins of the first transmission module through a CC1 cable and a CC2 cable, and the second end of the first transmission module is connected to the first end of the second transmission module by connecting multiple pins of the first transmission module except the hardware input / output pins (CC1, CC2, SUB and VBUS) and multiple pins of the second transmission module except the hardware input / output pins (CC1, CC2, SUB and VBUS) to the same contact.

[0062] Exemplarily, the connection between the second end of the second transmission module and the first end of the second input-output module can be a connection between the second input-output module and the hardware input / output (CC1, CC2, SUB and VBUS) pins of the second transmission module, the connection between the second end of the second input-output module and the first end of the second control module can be a connection between the I2C port, UART port, SPI port, ADC port, DAC port and RTC port of the second control module and the second input-output module respectively, the connection between the second end of the second control module and the first end of the second interface can be a connection between several pins of the second interface and the GPIO port of the second control module, and the connection between the second end of the second interface and the mobile terminal device can be an M.2 interface connected to the mobile terminal.

[0063] The first communication unit is used to determine the first IO attribute information and the first IO status information of the mobile broadband device when the mobile broadband device is inserted into the first interface, and send the first IO attribute information and the first IO status information to the second communication unit, so that the second communication unit adjusts the interface information of the second interface according to the first IO attribute information and the first IO status information; the second communication unit is used to determine the second IO attribute information and the second IO status information of the mobile terminal when the mobile terminal is inserted into the second interface, and send the second IO attribute information and the second IO status information to the first communication unit, so that the first communication unit adjusts the interface information of the first interface according to the second IO attribute information and the second IO status information.

[0064] It can be understood that when data is transmitted between the mobile broadband device and the mobile terminal, in order to ensure the integrity of the data during the data transmission process, the data interface of the mobile broadband device and the mobile terminal device during transmission can be adjusted when the mobile broadband device and the mobile terminal are inserted, that is, the first IO attribute information and the first IO state information of the first interface are adjusted, and the second IO attribute information and the second IO state information of the second interface are adjusted, thereby helping to ensure correct communication and data exchange between the mobile broadband device and the mobile terminal.

[0065] Optionally, the first communication unit can receive first IO attribute information and first IO status information of the mobile broadband device when the mobile broadband device is inserted into the first interface, and send the first IO attribute information and the first IO status information to the second communication unit, so that the second communication unit adjusts the interface information of the second interface according to the first IO attribute information and the first IO status information.

[0066] Optionally, the second communication unit can receive second IO attribute information and second IO status information of the mobile terminal when the mobile terminal is inserted into the second interface, and send the second IO attribute information and the second IO status information to the first communication unit, so that the first communication unit adjusts the interface information of the first interface according to the second IO attribute information and the second IO status information.

[0067] That is to say, the communication device provided in the embodiment of the present application can adjust the second interface according to the first IO attribute information and the first IO state information of the mobile broadband device during data transmission, and can also adjust the first interface according to the second IO attribute information and the second IO state information of the mobile terminal. For example, the adjustment scheme can be determined according to the insertion order of the mobile broadband device and the mobile terminal, which is not elaborated in this application.

[0068] Among them, the first IO attribute information refers to the basic attributes of the first interface, which may include the port type of the first interface (digital port or analog port), the data direction of the first interface (input port, output port or bidirectional port), the signal level of the first interface (voltage range when transmitting signals), the driving capability of the first interface (the current size that the port can provide), the pull-up / pull-down resistor of the first interface (whether there is a default state), and the interrupt function of the first interface (whether an interrupt signal is sent when the port state changes). The first IO state information refers to the real-time state or data value of the first interface when transmitting data at a certain moment, which may include the current level of the first interface (whether the port is at a high level or a low level), the data value of the first interface (the current data value or voltage value or current value of the port), the state change of the first interface, and the error state of the first interface.

[0069] Among them, the second IO attribute information refers to the basic attributes of the second interface, which may include the port type of the second interface (digital port or analog port), the data direction of the second interface (input port, output port or bidirectional port), the signal level of the second interface (voltage range when transmitting signals), the driving capability of the second interface (the current size that the port can provide), the pull-up / pull-down resistor of the second interface (whether there is a default state), and the interrupt function of the second interface (whether an interrupt signal is sent when the port state changes). The second IO state information refers to the real-time state or data value of the second interface when transmitting data at a certain moment, which may include the current level of the second interface (whether the port is at a high level or a low level), the data value of the second interface (the current data value or voltage value or current value of the port), the state change of the second interface, and the error state of the second interface.

[0070] Among them, mobile broadband devices can be devices that provide wireless high-speed Internet access services based on mobile communication networks (such as 2G, 3G, 4G, 5G, etc.), such as MBB devices (Mobile Broadband). Mobile terminals can be any device that needs to access the network, such as smartphones, tablet computers, and laptops.

[0071] The first communication unit is used to send data from the mobile broadband device to the second communication unit and send data from the second communication unit to the mobile broadband device through the first interface, the first control module, the first input-output module and the first transmission module; the second communication unit is used to send data from the mobile terminal to the first communication unit and send data from the first communication unit to the mobile terminal through the second interface, the second control module, the second input-output module and the second transmission module.

[0072] It can be understood that when the first interface and the second interface are adjusted to interfaces with the same IO attribute information and the same IO status information, the mobile broadband device and the mobile terminal can transmit data through the communication device provided in the embodiment of the present application, thereby ensuring the integrity of the signal transmission process between the mobile broadband device and the mobile terminal.

[0073] Optionally, the first communication unit can send out-of-band data from the mobile broadband device to the second communication unit through the first interface, the first control module, the first input-output module and the first transmission module. After receiving the data from the mobile broadband device, the second communication unit can send the out-of-band data from the mobile broadband device to the mobile terminal through the second transmission module, the second input-output module, the second control module and the second interface.

[0074] Optionally, the second communication unit can send out-of-band data from the mobile terminal to the first communication unit through the second interface, the second control module, the second input-output module and the second transmission module. After receiving the data from the mobile terminal, the first communication unit can send the out-of-band data from the mobile terminal to the mobile broadband device through the first transmission module, the first input-output module, the first control module and the first interface.

[0075] That is to say, the communication device provided in the embodiment of the present application is bidirectional during data transmission, and can be flexibly adjusted according to the needs of data transmission, which is not elaborated in this application.

[0076] In this embodiment, by setting a first communication unit and a second communication unit in the communication device, and setting a first interface, a first control module, a first input-output module and a first transmission module connected in sequence in the first communication unit, and setting a second interface, a second control module, a second input-output module and a second transmission module connected in sequence in the second communication unit, it is possible to adjust the first interface or the second interface after the mobile terminal broadband device and the mobile terminal device are connected, so that the first interface of the first communication unit and the second interface of the second communication unit can realize data transmission between the mobile broadband device and the mobile terminal with the same IO attribute information and the same IO status information, thereby ensuring the integrity of the signal transmission process between the mobile broadband device and the mobile terminal.

[0077] In one possible implementation, the first communication unit is also used to adjust the state of the first target pin of the first transmission module to the target state before sending data to the second communication unit, so that the state of the second target pin connected to the first target pin on the second transmission module is adjusted to the target state accordingly; the second communication unit is also used to adjust the state of the second target pin of the second transmission module to the target state before sending data to the first communication unit, so that the state of the first target pin connected to the second target pin on the first transmission module is adjusted to the target state accordingly.

[0078] It is understandable that when the mobile broadband device and the mobile terminal are transmitting data, in order to improve the integrity and accuracy of data during data transmission, the first communication unit and the second communication unit may also synchronize the timing during data transmission to avoid data loss or device failure.

[0079] Optionally, before sending data to the second communication unit, the first communication unit may adjust the state of the first target pin of the first transmission module to a target state, so that the state of the second target pin connected to the first target pin on the second transmission module is correspondingly adjusted to the target state. The target state may be adjusted from a pull-down state to a pull-up state or from a disconnected state to an accessed state.

[0080] For example, taking the mobile terminal as a device with a PCIe interface, the PCIe interface device has multiple I / O states such as Perst (Persist State) / Pwake (Power Wake) / CLKREQ (Clock Request), etc., and the idle pin (such as SBU2) of the first transmission module or the second transmission module can be used as the starting point of data transmission, thereby achieving precise timing synchronization between the first communication unit and the second communication unit regarding the changes in I / O states such as Perst, Pwake, CLKREQ, etc.

[0081] In a possible implementation manner, the first communication unit is specifically configured to:

[0082] The first IO attribute information and the first IO status information sent by the mobile broadband device are obtained through the first interface, the first IO attribute information and the first IO status information are encapsulated into a first IO message through the first control module, and the first IO message is sent to the second communication unit through the first input and output module and the first transmission module, so that the second communication unit adjusts the interface information of the second interface according to the first IO message.

[0083] It can be understood that IO attribute synchronization and IO status synchronization can be performed simultaneously or separately.

[0084] Exemplarily, when the mobile broadband device is inserted into the first interface, the communication apparatus provided in the embodiment of the present application may first perform IO attribute synchronization, and after the IO attribute synchronization is completed, perform IO status synchronization, and at the same time, continue to perform IO status synchronization during data transmission.

[0085] Optionally, Figure 2 A schematic diagram of synchronizing IO attribute information between a first communication unit and a second communication unit in a communication device provided in an embodiment of the present application, referring to Figure 2 As shown, the first communication unit can obtain the pre-configured first IO attribute information through the first interface, and pack the first IO attribute information into a first IO message through the first control module, and execute the uplink request for the first IO message through the first control module, and convert the first IO message into a coded signal through the first control module, and send it to the second communication unit through the first input and output module and the first transmission module.

[0086] Optionally, continue to refer to Figure 2As shown, the second communication unit receives the coded signal through the second input / output module and the second transmission module, parses the coded signal through the second control module, and parses the first IO message through the second control module to obtain the first IO attribute information, and configures the second interface according to the first IO attribute information.

[0087] Optionally, continue to refer to Figure 2 As shown, the second communication unit can also send a control message (GoodCRC) to the first communication unit to indicate that the first IO message has been received normally, so that after receiving the control message, the first communication unit determines through the first control module that the IO attribute synchronization between the first communication unit and the second communication unit has been completed.

[0088] Optionally, Figure 3 A schematic diagram of the synchronization of IO status information between the first communication unit and the second communication unit in the communication device provided in the embodiment of the present application, referring to Figure 3 As shown, the first communication unit can obtain the first IO status information through the first interface, and pack the first IO status information into a first IO message through the first control module, and execute the uplink request for the first IO message through the first control module, and convert the first IO message into a coded signal through the first control module, and send it to the second communication unit through the first input and output module and the first transmission module.

[0089] Optionally, continue to refer to Figure 3 As shown, the second communication unit receives the coded signal through the second input / output module and the second transmission module, parses the coded signal through the second control module, and parses the first IO message through the second control module to obtain the first IO state information, and configures the second interface according to the first IO state information.

[0090] Optionally, continue to refer to Figure 3 As shown, the second communication unit can also send a control message (GoodCRC) to the first communication unit to indicate that the first IO message has been received normally, so that after receiving the control message, the first communication unit determines through the first control module that the IO state synchronization between the first communication unit and the second communication unit has been completed.

[0091] The first IO attribute information and the first IO status information sent by the mobile broadband device are obtained through the first interface, the first IO attribute information and the first IO status information are encapsulated as a first IO message through the first control module, and the first IO message is sent to the second communication unit through the first input and output module and the first transmission module, so that the second communication unit adjusts the interface information of the second interface according to the first IO message, which can ensure that the integrity and consistency of the data are maintained during the data reading and writing process, and at the same time, reduce the crash or instability of the mobile broadband device and the mobile terminal caused by inconsistent input and output operations, thereby ensuring the overall performance of the communication device provided in the embodiment of the present application.

[0092] In a possible implementation manner, the second communication unit is specifically configured to:

[0093] The second IO attribute information and the second IO status information sent by the mobile terminal are obtained through the second interface, the second IO attribute information and the second IO status information are encapsulated into a second IO message through the second control module, and the second IO message is sent to the first communication unit through the second input and output module and the second transmission module, so that the first communication unit adjusts the interface information of the first interface according to the second IO message.

[0094] It can be understood that IO attribute synchronization and IO status synchronization can be performed simultaneously or separately.
