[0002] Currently, with the pursuit of rate, latency, high-speed mobility, and energy efficiency by people, as well as the diversity and complexity of services in future life, the international standard organization has started to research 5G. The main application scenarios of 5G are: enhanced mobile broadband (eMBB), ultra reliability and low latency communication (URLLC), and massive machine type communications (mMTC).

[0040] At least one embodiment of the present invention provides an industrial gateway.Figure 1 Schematic diagram of the industrial gateway of the present invention. As Figure 1 shown, the industrial gateway 1 includes a user information module 3, a main control module 2, and a single-mode module 10. The main control module 2 has a registration and connection management sub-module 21. The user information module 3 is configured to store user information.

The single-mode module 10 is configured to connect the industrial gateway 1 to the network service platform and input the user information into the network service platform for registration to establish a data channel.

[0041] For example, the main control module 2 is connected to the user information module 3, and the registration and connection management sub-module 21 in the main control module 2 reads the user information in the user information module 3. The user information module 3 is connected to the single-mode module 10 to connect the industrial gateway 1 to the network service platform and send the user information to the network service platform for registration to establish a data channel between the industrial gateway 1 and the network service platform, so that the industrial gateway 1 can send the data received from the external devices connected to the lower layer of the industrial gateway through the data channel to the network service platform through the single-mode module 10, and send the data received from the data channel to the external devices connected to the lower layer of the industrial gateway 1 through the single-mode module 10.

[0043] At least one embodiment of the present invention provides another industrial gateway 1. Figure 2 Another schematic diagram of the industrial gateway 1 of the present invention. As Figure 2 shown, on the basis of the embodiment shown in Figure 1 the industrial gateway 1 further includes a protocol conversion module 4, a storage module 5, an external interface 6, and a power module 8 and a power switch module 9.

For example, the single-mode module 10 is a single-mode WiFi module, and the communication module in the single-mode WiFi module is a WiFi communication module. For example, the industrial gateway 1 sends the data received from the external devices connected to the lower layer of the industrial gateway to the network service platform through the data channel via the WiFi communication module in the single-mode WiFi module, and sends the data received from the data channel to the external devices connected to the lower layer of the industrial gateway 1 through the WiFi communication module in the single-mode WiFi module. For example, the external devices connected to the lower layer of the industrial gateway can be the terminal devices 7 accessing the Internet of Things.

The single-mode module 10 can also be other single-mode modules 10. For example, a Bluetooth single-mode module 10 or a Zigbee single-mode module 10, and the working principle of the single-mode module 10 remains unchanged, which will not be limited here.

[0046] The main control module 2 is configured to use a general-purpose embedded multi-core CPU (as well as ROM and RAM) in the industry.

The registration and connection management sub-module 21 is also configured to call the EAP-5G authentication protocol stack and the NWu interface protocol stack, and connect to the network service platform through the communication module 11 in the single-mode module 10 for registration. For another example, the registration and connection management sub-module 21 reads the user information in the user information module 3, such as cellular network user information, calls the built-in EAP-5G authentication protocol stack and NAS mobility management protocol that conform to the 3GPP standard, and performs EAP authentication through the WiFi AP and N3IWF on the network side to the AMF / SMF, and establishes an NWu interface with the N3IWF.

[0047] The protocol conversion module 4 is configured to convert the data of the terminal devices 7 using different protocol types into the general protocol data supported by the network service platform. For example, the protocol conversion module 4 is connected to the external interface 6 and the user information module 3. The protocol conversion module 4 is configured to convert the data input by the terminal devices 7 using different protocol types through the external interface 6 into the general protocol data supported by the network service platform, send the general protocol data to the user information module 3, and send it to the network service platform through the communication module 11 in the single-mode module 10 via the data channel. Another example is that the protocol conversion module 4 converts the data input by the network service platform using different protocol types received from the user information module 3 through the communication module 11 in the single-mode module 10 via the data channel into the general protocol data supported by the terminal device 7, and sends the general protocol data to the terminal device 7 through the external interface 6.

[0048] The session management sub-module 22 is configured to instruct the protocol conversion module 4 to send the general protocol data to the network service platform through the single-mode module 10 via the data channel. For example, the session management sub-module 22 is configured to interact with the terminal device 7 through the external interface 6 to obtain a data transmission instruction, and is configured to instruct the wireless communication module to access the data of the terminal device 7 from the external interface 6. After the protocol conversion module 4 converts the data into a protocol format recognizable by the service platform, it is configured to instruct the protocol conversion module 4 to transmit the converted data to the network side N3IWF through the user information module 3 and the communication module in the single-mode module 10, and then transmit it to the network service platform through the UPF. The session management sub-module 22 is also configured to instruct the protocol conversion module 4 to convert the data received through the single-mode module 10 via the data channel into the general protocol data supported by the terminal device 7, and send the general protocol data to the terminal device through the external interface.

For example, the storage management sub-module 23 is configured to import the data of the terminal device 7 into the storage module 5 through the external interface 6 according to settings or upon receiving an instruction from the terminal device 7. When the set time arrives, the main control module 2 detects whether the data channel is connected, converts the data of the terminal device 7 with different protocol types stored in the storage module 5 into general protocol data supported by the network service platform, and sends the data to the network service platform. Similarly, the storage management sub-module 23 is further configured to import the data of the network service platform into the storage module 5. In this case, the protocol conversion module 4 is further configured to convert the data of the network service platform with different protocol types in the storage module 5 into general protocol data supported by the terminal device 7.

[0053] In the industrial gateway of this embodiment, the storage module 5 is configured to store data that does not need to be forwarded to the network in real time and delay the data forwarding as required, so that data can be transmitted as needed when required; the session management sub-module 22 is configured to instruct the protocol conversion module 4 to convert the data of the terminal device 7 using different protocol types into the general protocol data supported by the network service platform, and send the general protocol data to the network service platform via the data channel through the single-mode module 10, thereby further realizing the access of the industrial gateway 1 to the network service platform through the single-mode module 10 without configuring a 5G industrial module, thereby further reducing the cost of the industrial gateway 1.
