[0076] In the embodiment, the first communication unit and the second communication unit are arranged in the communication device, the first interface, the first control module, the first input / output module and the first transmission module are sequentially connected in the first communication unit, and the second interface, the second control module, the second input / output module and the second transmission module are sequentially connected in the second communication unit, so that the first interface or the second interface can be adjusted after the mobile terminal broadband device and the mobile terminal device are accessed, 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 state information, and the integrity of the signal transmission process between the mobile broadband device and the mobile terminal is ensured.

[0077] In a possible implementation, the first communication unit is further configured to adjust a state of a first target pin of the first transmission module to a target state before sending data to the second communication unit, so that a state of a second target pin connected with the first target pin on the second transmission module is adjusted to the target state correspondingly; and the second communication unit is further configured to adjust a state of a second target pin of the second transmission module to a target state before sending data to the first communication unit, so that a state of a first target pin connected with the second target pin on the first transmission module is adjusted to the target state correspondingly.

[0078] It can be understood that, in order to improve the integrity and accuracy of data in the data transmission process, the first communication unit and the second communication unit can also synchronize the timing in the data transmission process, so as to avoid data loss or device failure.

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

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

[0091] The first IO attribute information and the first IO state information sent by the mobile broadband device are acquired through the first interface, the first IO attribute information and the first IO state information are encapsulated into first IO messages by the first control module, and the first IO messages are 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 messages, the integrity and consistency of data can be maintained in the data reading and writing process, meanwhile, the collapse or unstable situation caused by the inconsistency of input and output operations of the mobile broadband device and the mobile terminal is reduced, and the overall performance of the communication device provided by the embodiment of the application is ensured.

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

[0093] The second IO attribute information and the second IO state information sent by the mobile terminal are acquired through the second interface, the second IO attribute information and the second IO state information are encapsulated into second IO messages by the second control module, and the second IO messages are 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 messages.

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

[0095] Exemplarily, when the mobile terminal is inserted into the second interface, the communication device provided by the embodiment of the application can first perform the IO attribute synchronization, and then perform the IO state synchronization after the IO attribute synchronization is completed, and meanwhile, the IO state synchronization is continuously performed in the data transmission process.
