[0050] Reference Figure 7The embodiment of the present invention provides a communication method based on a docking station 200 and a mobile terminal 100, which is applied to a mobile office system. The mobile office system includes a mobile terminal 100 and a docking station 200. The mobile terminal 100 is provided with a first USB interface 110, and the docking station 200 is provided with a second USB interface 120. The mobile terminal 100 and the docking station 200 are connected through the first USB interface 110 and the second USB interface 120. And the first driver layer of the mobile terminal 100 and the second driver layer of the docking station 200 are used to realize the batch transmission of the handshake protocol between the first USB interface 110 and the second USB interface 120. Among them, the mobile terminal 100 is used as a master device, and the docking station 200 is used as a slave device. All communications are initiated by the mobile terminal 100, and the docking station 200 responds. Thereby, mutual recognition between the mobile terminal 100 and the docking station 200 is realized, and the security during the execution of the business is improved. It should be noted that the mobile terminal 100 in this embodiment can be a smart device such as a tablet computer, and this embodiment is not specifically limited.

[0051] The control method of the embodiment of the present invention is further described below based on the accompanying drawings.

[0052] Reference Figure 1 , Figure 1 A flow chart of a communication method based on a docking station 200 and a mobile terminal 100 provided in an embodiment of the present invention, the communication method based on the docking station 200 and the mobile terminal 100 includes but is not limited to the following steps:

[0053] Step S11, obtaining communication protocol information of the first USB interface 110 and the second USB interface 120;

[0054] It should be noted that by obtaining the communication protocol information of the first USB interface 110 and the second USB interface 120, the communication protocol compatibility between the mobile terminal 100 and the docking station 200 is ensured. Only when the communication protocols between the mobile terminal 100 and the docking station 200 match can stable data transmission be achieved.

[0055] Step S12, the mobile terminal 100 sends a first communication signal to the docking station 200 according to the communication protocol information, and the docking station 200 responds to the first communication signal and receives a plurality of transmission data packets sent by the mobile terminal 100 to the docking station 200, wherein a device whitelist is preset in the mobile terminal 100;

[0056] It should be noted that the device whitelist mechanism can ensure that only the mobile terminal 100 and the expansion dock 200 that have been authenticated and authorized by the handshake protocol can communicate and transmit data, prevent unauthorized device connection, and thus avoid the risk of data leakage and tampering. By following the communication protocol of the first USB interface 110 and the second USB interface 120, the mobile terminal 100 and the expansion dock 200 can ensure that the communication between the two parties is accurate and reliable. Further avoid the occurrence of communication errors or data loss caused by protocol mismatch. In addition, the expansion dock 200 can quickly respond to the first communication signal sent by the mobile terminal 100, thereby shortening the waiting time for data transmission, and the mobile terminal 100 can send multiple transmission data packets to the expansion dock 200, reducing redundancy and repetition in the data transmission process, and improving the speed and efficiency of data transmission.

[0057] Step S13, the mobile terminal 100 and the docking station 200 both extract multiple data transmission packets to obtain first field information and second field information;

[0058] It should be noted that during the data transmission process, data transmission packets may be lost or damaged due to network fluctuations, equipment failures, etc. This embodiment extracts and parses multiple data transmission packets to obtain first field information and second field information, and can recover and restore the original data to the greatest extent, thereby ensuring the integrity of the data.

[0059] Step S14, matching the first field information and the second field information with the device whitelist respectively;

[0060] It should be noted that, by matching the first field information and the second field information with the device whitelist respectively, a preliminary bidirectional communication connection comparison between the docking station 200 and the mobile terminal 100 is achieved.

[0061] Step S15 , when the first field information and the second field information successfully match the device whitelist, the mobile terminal 100 is successfully connected to the docking station 200 .

[0062] It should be noted that only when the first field information and the second field information successfully match the device whitelist, can an effective connection be established between the mobile terminal 100 and the docking station 200. This ensures that only authenticated and authorized devices can access or transmit data, and verifies the source and legitimacy of the data. This ensures the accuracy and consistency of the data, prevents data from being tampered with or forged, and ensures the safety of the device.

[0063] It should be noted that the mobile terminal 100 and the expansion dock 200 are connected through the communication protocol between the first USB interface 110 and the second USB interface 120, thereby realizing a two-way authentication process between the mobile terminal 100 and the expansion dock 200, which significantly improves the credibility and security of data transmission and device connection, ensures that only devices that have been trusted and verified can communicate with each other, and effectively blocks the access of non-authenticated devices at the physical interface level, thereby preventing the expansion dock 200 or mobile terminal 100 that has not been successfully identified from accessing the system, thereby ensuring the security of business scenarios.

[0064] In addition, in one embodiment, referring to Figure 2 ,exist Figure 1 Step S14 of the illustrated embodiment also includes but is not limited to the following steps:

[0065] Step S21, when the first field information and the second field information fail to match the device whitelist, the docking station 200 stops receiving the transmission data packet sent by the mobile terminal 100;

[0066] Step S22 : the mobile terminal 100 is disconnected from the docking station 200 .

[0067] It should be noted that by matching and verifying the field information with the device whitelist respectively, when the expansion dock 200 or the mobile terminal 100 fails to successfully match the device whitelist, the mobile terminal 100 can quickly stop sending transmission data packets to the expansion dock 200 and disconnect the connection, thereby effectively preventing data leakage and illegal access.

[0068] In addition, in one embodiment, referring to Figure 3 ,exist Figure 1 Step S12 of the illustrated embodiment also includes but is not limited to the following steps:

[0069] Step S31, obtaining a first time period and a second time period of the mobile terminal 100;

[0070] Step S32, when the communication time of the mobile terminal 100 reaches the first time period, the mobile terminal 100 sends a first communication signal to the docking station 200, wherein the mobile terminal 100 cyclically sends the first communication signal to the docking station 200 according to a preset cycle period;

[0071] Step S33 , when the communication time reaches the second time period, it is determined that the mobile terminal 100 and the docking station 200 are not successfully connected, and the connection between the mobile terminal 100 and the docking station 200 fails.

[0072] It should be noted that, in the present embodiment, the first time period is 3 seconds, and the second time period is 10 seconds. Specifically, when the communication time of the mobile terminal 100 reaches the first time period (i.e., every 3 seconds), the mobile terminal 100 initiates a complete communication process, and the docking station 200 responds. When the communication time reaches the second time period (i.e., within 10 seconds, no communication connection is established between the mobile terminal 100 and the docking station 200 for three consecutive times), the communication is considered to have failed. After the communication fails, the docking station 200 will no longer receive USB data from the mobile terminal 100. At the same time, the docking station 200 is also unable to directly transmit data to the mobile terminal 100 through the first USB interface 110 and the second USB interface 120, thereby achieving the effect of two-way data disconnection, ensuring the safety of device use between the mobile terminal 100 and the docking station 200.

[0073] In addition, in one embodiment, referring to Figure 4 ,exist Figure 3 After step S31 in the illustrated embodiment, the following steps are also included but not limited to:

[0074] Step S41, before the communication time reaches the first time period, the mobile terminal 100 sends a request instruction message and a request response message to the docking station 200;

[0075] Step S42, the docking station 200 sends a ready instruction and a ready response to the mobile terminal 100 according to the request instruction information and the request response information;

[0076] Step S43 , when the communication time reaches the first time period, the mobile terminal 100 resends the request instruction information and the request response information to the docking station 200 .

[0077] It should be noted that the mobile terminal 100 sends a request instruction and corresponding information before the communication time reaches the first time period, so that the docking station 200 can quickly identify and respond to the instruction information sent by the mobile terminal 100, so that the mobile terminal 100 and the docking station 200 can quickly and stably establish a communication connection, reduce the delay in the communication process through a timely request and response mechanism, and further improve the efficiency and speed of data transmission. Furthermore, after receiving the request instruction from the mobile terminal 100, the docking station 200 quickly sends a ready instruction to the mobile terminal 100 to confirm that the docking station 200 can receive or process subsequent data transmission in a timely manner. After the first time period, the request instruction and response information are resent to ensure that the mobile terminal 100 can cyclically send the first communication signal to the docking station 200 according to the preset cycle period, thereby completing the complete communication process.

[0078] In addition, in one embodiment, referring to Figure 5 ,exist Figure 1Step S13 of the illustrated embodiment also includes but is not limited to the following steps:

[0079] Step S51, obtaining a plurality of first character strings in the first field information and a plurality of second character strings in the second field information, wherein the first character string and the second character string at least include device information, device model information and serial number information;

[0080] Step S52, obtaining third string information of the device whitelist, and matching the first string and the second string with the third string respectively;

[0081] Step S53 , when the first character string, the second character string and the third character string are not successfully matched, the communication between the mobile terminal 100 and the docking station 200 is stopped.

[0082] It should be noted that after the communication connection is successfully established between the mobile terminal 100 and the expansion dock 200, the mobile terminal 100 and the expansion dock 200 respectively extract the first field information and the second field information in the data packet, wherein the first field information and the second field information are both HWID fields; further, the mobile terminal 100 and the expansion dock 200 respectively obtain the first character string and the second character string in the first field information and the second field information, wherein the first character string and the second character string both include the device manufacturer, product model and product serial number.

[0083] Furthermore, the third string in the device whitelist is obtained, and the first string and the second string are matched with the third string respectively. When the first string and the second string do not successfully match the third string, the communication is terminated. In this way, invalid data transmission caused by unauthorized device access is reduced, and during the data transmission process, the legitimacy of the device is verified to ensure that the data will not be intercepted or tampered by unauthorized devices, further ensuring the confidentiality and integrity of the data during the business.

[0084] In addition, in one embodiment, referring to Figure 6 ,exist Figure 1 After step S15 of the illustrated embodiment, the following steps are also included but not limited to:

[0085] Step S61, the mobile terminal 100 and the docking station 200 both obtain first event information;

[0086] Step S62, the first driving layer of the mobile terminal 100 sends the first event information to the first application layer, and the second driving layer of the docking station 200 sends the first event information to the second application layer;

[0087] Step S63, when the first service layer of the mobile terminal 100 and the second service layer of the docking station 200 receive the first event information received by the first application layer and the second application layer respectively, it is determined that the mobile terminal 100 and the docking station 200 are successfully connected, and the service process is executed;

[0088] Step S64 , when the first application layer and the second application layer do not receive the first event information, it is determined that the mobile terminal 100 and the docking station 200 are not successfully connected, and the mobile terminal 100 stops sending the first communication signal to the docking station 200 .

[0089] It should be noted that the mobile terminal 100 is provided with a first driver layer, a first application layer and a first business layer, and the docking station 200 is provided with a second driver layer, a second application layer and a first business layer. After the mobile terminal 100 and the docking station 200 are successfully connected in communication, the first driver layer and the second driver layer send first event information to the first application layer and the second application layer respectively. Exemplarily, the first event information is an online event. When the first business layer and the second business layer receive the "online@ / devices / virtual / misc / dcm" event, it is determined that the mobile terminal 100 and the docking station 200 are successfully connected and start to execute the business process; when the first application layer and the second application layer do not receive the first time information, it is determined that the mobile terminal 100 and the docking station 200 are not successfully connected, and the mobile terminal 100 no longer sends business-related data to the docking station 200 through the first USB interface 110 and the second USB interface 120.
