Elaborate

In order to make the purpose, technical solutions and advantages of the embodiments of the present disclosure clearer, the technical solutions in the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings in the embodiments of the present disclosure. Obviously, the described embodiments These are some embodiments of the present disclosure, but not all embodiments. Based on the embodiments in this disclosure, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of this disclosure.

Please refer to Figure 1, which is a flow chart of a communication method provided by an embodiment of the present disclosure. The method includes:

S101: Determine whether the communication status indication message sent by the host side is received within the preset timer time;

S102: If the communication status indication message is received within the preset timer time, confirm that the terminal device is in a normal working state, and establish the wireless communication module and the first SIM card based on the communication status indication message and the first SIM card. Wireless communication of cloud servers; and

S103: If the communication status indication message is not received within the preset timer time, confirm that the terminal device is in an offline working state, and use the second SIM card to establish the Wireless communication between the wireless communication module and the cloud server.

Embodiments of the present disclosure may be applied to terminal devices including wireless communication modules, and the communication status indication message may be used to indicate the current communication status or communication status of the terminal device. The specific type and content of the communication status indication message are not limited here. In some implementations, MBIM messages may be used. MBIM messages refer to Mobile Broadband Interface Model messages and may be used to feedback mobile communication status. Step S101 can be executed at any time to detect the terminal device and adjust the working status of the terminal device.

The preset timer time is not limited here. It can be set by those skilled in the art, such as 1 minute, 3 minutes, etc. Of course, by default in step S101, the preset timer time can be set by those skilled in the art before executing step S101.

In step S101, it is necessary to judge whether the communication status indication message received by the host side is a communication status indication message sent by the host side according to the preset timer time. The execution subject of this process may be a module related to the communication mode in the terminal device, for example Wireless communication module, or control module of communication module, etc.

In step S102, if the communication status indication message is received within the preset timer time, that is, it is determined that the terminal device is in the mobile broadband connection process, and the terminal device is in a normal working state. At this time, the communication status can be directly determined according to the communication status. Instruction message to establish wireless communication.

The process of establishing wireless communication may include processes such as network registration and dial-up connection.

In some embodiments, one possible implementation is as follows:

S102A: If the communication status indication message is received within the preset timer time, send a system online event;

S102B: Confirm that the terminal device is in normal working status according to the system online event;

S102C: Use the protocol stack to perform network registration based on the communication status indication message;

S102D: After successful network registration, use the wireless communication module as an MQTT client and initiate a dial-up connection to the cloud server based on the MQTT protocol;

S102E: After the dial-up connection is successful, establish wireless communication between the wireless communication module and the cloud server.

In the above process, taking the wireless communication module as the execution subject as an example, when the terminal device is powered on After startup, if a communication status indication message is received within the preset timer time, control messages including network registration, dial-up connection, etc. can be obtained, and these control messages are sent to the protocol stack to realize wireless network connection.

At this time, the wireless communication module can send system online events to the device mode management sub-function configured to perform device mode management in the terminal device. After receiving the system online event, the device mode management sub-function confirms that the wireless communication module is online and can use mobile Operates in broadband mode.

After the protocol stack receives the control information, it needs to perform network registration and dial-up connection. After the network registration is successful, a network registration success message will be received. At this time, the wireless communication module can be used as an MQTT client to initiate a dial-up connection to the cloud server using the MQTT protocol. After the dial-up connection is established, the wireless communication module will establish a wireless communication connection with the cloud server. The MQTT client is a communication end that applies the MQTT protocol. The MQTT protocol is Message Queuing Telemetry Transport, which is a message publishing/subscription transmission protocol based on client-server.

Of course, when actually performing wireless communication between the wireless communication module and the cloud server, those skilled in the art can also refer to the above process and adopt other protocols, which are not limited to examples here.

Once the communication status indication message is not received within the preset timer time, it indicates that the terminal device does not perform mobile broadband connection at this time, and the terminal device is in an offline working state. It should be noted that the offline working state refers to the operating state of the terminal device considered when no communication status indication message is received within the preset timer time, and does not represent the current actual operating state of the terminal device. Usually, the offline working state is when the terminal device is in a sleep or shutdown state. At this time, the hardware of the terminal device is in a power-off state, and the corresponding wireless communication module is also in a power-off state. At this time, the diagnostic device is in an offline working state.

In step S103, when the terminal device is in an offline working state, the second SIM card is used to establish wireless communication between the wireless communication module and the cloud server. There is no specific limitation on the second SIM card here, and the remaining first SIM cards are SIM cards used in different communication modes. In a preferred implementation manner, the second SIM card may be a built-in eSIM card. When establishing wireless communication with the cloud server using the second SIM card, various IoT protocols can be applied. It should be noted that only one SIM card can be working at any time.

In some embodiments, taking the Windows operating system as an example, the Windows operating system The wireless network connection of the operating system is based on the DSSA (Dual SIM Single Active, dual SIM Single Active) method, and the wireless communication module is also based on the DSSA method, that is, both the Windows OS and the wireless communication module work based on the dual SIM single standby mode. At this time, the dual SIM The USIM card external to the terminal device and the eSIM card built into the wireless communication module can be used.

Before performing step S103, you can also power the wireless communication module through the embedded controller integrated on the host side of the terminal device, switch the current operating mode of the terminal device from the mobile broadband mode to the IoT mode, and change the currently applied The SIM card is switched from the first SIM card to the second SIM card.

In addition, the status of the wireless communication module can also be confirmed through events. In some implementations, a system offline event may be generated, and upon receipt of the system offline event, it may be determined that the wireless communication module is in an offline state. This allows you to switch the operating mode of the terminal device and switch the applied SIM card.

Thereafter, the preset file of the second SIM card can be activated, the preset file can be used to perform the network registration process, and a network connection can be established after successful network registration.

There is no limit on how to use the preset file to perform the network registration process, which may include the following steps:

Send a network registration request to the protocol stack based on the preconfigured file;

After the protocol stack is successfully registered in the network, a registration success message is received; and

According to the registration success message, the wireless communication module is connected to the cloud server through the preset wireless communication protocol.

As can be seen from the above process, the protocol stack can also be used to perform network registration. At the same time, after the network registration is successful, the wireless communication module is used as an MQTT client and initiates a dial-up connection to the cloud server based on the MQTT protocol to implement IoT applications for terminal devices. .

In order to facilitate the use of the terminal device, the mobile broadband mode of the terminal device can be set as the default operating mode. In this way, when the terminal device is running normally, the mobile broadband mode is adopted by default. Once it is detected that the communication status indication message is not received within the preset timer time, it can be switched to the offline working state and enter the IoT mode.

Embodiments of the present disclosure can determine the current working status of the terminal device by detecting whether the communication status indication message sent by the host side is received within the preset timer, and adopt different connection methods according to the current working status of the terminal device. Build with the cloud The connection to the server ensures that the terminal device remains connected to the cloud in any working state, meeting user needs and ensuring high availability of the terminal device.

When the communication status indication message processing sub-function receives the communication status indication message, it will send a system online event to the device mode management (Device Mode Manager) sub-function;

After the terminal device is started, the device mode management sub-function defaults to MBB mode. After receiving the system online event, it confirms that the wireless communication module is online and maintains the default MBB mode;

The control process of the protocol stack is based on the communication status indication message. After the network injection is successful, the dial-up connection management (Connection Manager) sub-function will receive the network injection success message;

The dial-up connection management sub-function receives the message that the network registration is successful, uses the wireless communication module as the MQTT client (MQTT Client), and uses the first SIM card to initiate a dial-up connection to the cloud server (Cloud Server) based on the MQTT protocol; and

After the dial-up connection is established, the wireless communication module establishes a wireless communication connection with the cloud server.

Please refer to Figure 3. Figure 3 is a schematic diagram of the communication process of the terminal device in the IoT mode provided by an embodiment of the present disclosure. This process is the communication process in the IoT mode, with the sub-functions and specific components involved in the communication process. Describe the specific communication process, which may include:
