[0045] To enable those skilled in the art to better understand the present application, the present application will be further described in detail below with reference to the accompanying drawings and specific embodiments. Obviously, the described embodiments are merely some embodiments of the present application, and not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0046] Please refer to Figure 1 , Figure 1This is a flowchart illustrating a configuration download control method according to an embodiment of this application. The method is applied to a communication device, which includes a client, a wireless wide area network module, a host, and an eSIM card. The method includes the following steps:

[0047] S101. After the wireless wide area network module is powered on, the eSIM card is dynamically configured and downloaded based on the client's activation or deactivation request.

[0048] Among them, the Wireless Wide Area Network (WWAN) module is a hardware component that enables the device to achieve wide-area wireless communication, allowing the device to disconnect from the wired network and access the cellular mobile network (such as 4G and 5G) provided by the operator.

[0049] An eSIM (Embedded Subscriber Identity Module) is an embedded SIM card, a next-generation standard developed by the GSMA. Unlike traditional pluggable SIM cards, eSIM cards are directly embedded in a chip. Once user information is written, services such as calls and text messages can be enabled, and local networks can be quickly accessed globally.

[0050] Considering that the DPD port is only used during DPD activation and deactivation, it is unnecessary for the DPD port to remain in a long enumeration state. Therefore, in this embodiment, the eSIM card can be dynamically configured and downloaded only based on the client's activation or deactivation request. In other words, the eSIM card is dynamically configured and downloaded only when the client initiates an activation or deactivation request; that is, the DPD port is enumerated only during the activation or deactivation process.

[0051] For details on how DPD ports are enumerated during activation or deactivation, please refer to the specific implementation process of DPD port enumeration. This embodiment does not limit this process.

[0052] S102. After the dynamic configuration download port of the wireless wide area network module is activated or deactivated, the host sends a port closure message to the wireless wide area network module.

[0053] To avoid enumerating DPD ports after activation or deactivation, in this embodiment, the host can send a port close message to the wireless WAN module after the dynamic configuration download port of the wireless WAN module is activated or deactivated.

[0054] Specifically, after receiving the activation / deactivation request and completing the activation / deactivation operation, the Host EC will return a message to the wireless WAN module to close the port.

[0055] S103 The wireless WAN module disables the dynamic configuration download port based on the port close message and sends a response message to the host that the port is closed.

[0056] In one specific embodiment of this application, the wireless wide area network (WAN) module disables the dynamic configuration download port based on a port close message, including: the WAN module parses the port close message and disables the dynamic configuration download port based on the parsing result. That is, the WAN module parses the port close message sent by the host, thereby closing the port.

[0057] After disabling the DPD port, the wireless WAN module can send a response message to the host indicating that the port is closed.

[0058] S104. After receiving the response message, the host controls the client to hide the dynamically configured download port.

[0059] After receiving the response message, the host hides the DPD port in the client.

[0060] Specifically, controlling the client to hide the dynamically configured download port includes: controlling the client to disable the dynamically configured download port; and hiding only the DPD port, making it invisible.

[0061] The method provided in this application, applied to a communication device including a client, a wireless wide area network (WAN) module, a host, and an eSIM card, includes: after the WAN module is powered on, dynamically configuring the eSIM card based on an activation or deactivation request from the client; after the WAN module's dynamic configuration download port is activated or deactivated, the host sends a port close message to the WAN module; the WAN module disables the dynamic configuration download port based on the port close message and sends a response message to the host indicating that the port is closed; after receiving the response message, the host controls the client to hide the dynamic configuration download port.

[0062] In practical applications, the DPD port is only used during DPD activation and deactivation; that is, there is no need for the DPD port to remain in a long enumeration state. Therefore, in this application, after the wireless wide area network (WAN) module is powered on, the eSIM card can be dynamically configured via activation or deactivation requests from the client. After the WAN module's dynamic configuration download port is activated or deactivated, the host communicates with the WAN module to disable the dynamic configuration download port and control the client to hide it. In this way, this application can change the long enumeration state of the DPD port to a dynamic enumeration state, satisfying dynamic configuration download while reducing security risks and power consumption.

[0063] It should be noted that, based on the above embodiments, the embodiments of this application also provide corresponding improvement schemes. In the preferred / improved embodiments, the same or corresponding steps as in the above embodiments can be referred to each other, and the corresponding beneficial effects can also be referred to each other; however, these will not be elaborated upon in the preferred / improved embodiments herein.

[0064] In one specific embodiment of this application, dynamically downloading the eSIM card configuration based on the client's activation request includes:

[0065] The client sends an activation request to the IoT server, so that the IoT server can send an activation request to the wireless wide area network module based on the message queue telemetry transmission protocol;

[0066] Upon receiving an activation request, the wireless wide area network module sends the activation request to the host;

[0067] The host computer responds with a command-formatted message and sends the command-formatted message to the wireless wide area network module to dynamically download the eSIM card configuration.

[0068] The client sends an activation request to the IoT server, including:

[0069] The client sends an activation request to the IoT server via the transport protocol server.

[0070] Upon receiving an activation request, the wireless wide area network module sends the activation request to the host, including:

[0071] When the wireless wide area network module receives an activation / deactivation request, it transmits the activation request to the host via the I2C protocol.

[0072] In one specific embodiment of this application, dynamically downloading the eSIM card configuration based on the client's deactivation request includes:

[0073] The client sends a deactivation request to the IoT server, so that the IoT server can send a deactivation request to the wireless wide area network module based on the message queue telemetry transport protocol.

[0074] Upon receiving a deactivation request, the wireless wide area network module sends the deactivation request to the host;

[0075] The host computer responds with a command-formatted message and sends the command-formatted message to the wireless wide area network module to dynamically download the eSIM card configuration.

[0076] Considering the similar activation and deactivation processes, the following will combine... Figure 2 This section explains how to implement dynamic DPD port enumeration by combining the activation and deactivation processes.

[0077] That is, after the WWAN module is powered on, the end user (client) performs activation / deactivation operations through the TP server (transmission protocol server). The TP server receives the end user's request and sends the request to the TMX server (Internet of Things server, i.e., the server corresponding to the ThingsMatrix platform).

[0078] Then, the TMX server sends the end user's activation / deactivation request to the wireless wide area network module via the MQTT protocol.

[0079] After receiving the activation / deactivation request, the wireless wide area network module transmits it to the host EC via the I2C protocol (Inter-Integrated Circuit, a serial communication protocol). After receiving the request from the upper layer application, the host EC (where EC is an embedded controller) assembles a response command format message and sends it to the wireless wide area network module, thereby completing the DPD process.

[0080] Upon receiving and completing the activation / deactivation request, the Host EC sends a message to the WLAN module indicating that the DPD port is hidden. The WLAN module parses the message from the Host EC, thus closing the port configuration. The WLAN module returns the result to the Host EC, ultimately displaying the hidden DPD port on the End User side, thereby achieving the effect of dynamic enumeration.

[0081] That is, in this application, when a DPD port is needed, the TMX server issues a command, the module and EC communicate, and switch the port mode of the module, thereby switching the long enumeration mode of the DPD port to dynamic enumeration, so as to achieve the features of reducing power consumption and product security.

[0082] In other words, by dynamically enumerating DPD ports, power consumption is reduced and customer experience is improved. At the same time, dynamic port enumeration can reduce unauthorized intrusion and network attacks, which has a crucial impact on product security.

[0083] Corresponding to the above method embodiments, this application also provides a communication device. The communication device described below and the configuration download control method described above can be referred to in correspondence.

[0085] Among them, after the wireless wide area network module is powered on, the eSIM card is dynamically configured and downloaded based on the client's activation or deactivation request;

[0086] After the dynamic configuration download port of the wireless wide area network module is activated or deactivated, the host sends a port closure message to the wireless wide area network module.

[0087] The wireless wide area network module disables the dynamically configured download port based on the port close message and sends a response message to the host that the port is closed.

[0088] After receiving the response message, the host controls the client to hide the dynamically configured download port.

[0089] The communication device provided in this application includes a client, a wireless wide area network (WAN) module, a host, and an eSIM card. After the WAN module is powered on, it dynamically downloads configuration information for the eSIM card based on the client's activation or deactivation request. After the WAN module's dynamic configuration download port is activated or deactivated, the host sends a port close message to the WAN module. The WAN module disables the dynamic configuration download port based on the port close message and sends a response message to the host confirming that the port is closed. After receiving the response message, the host controls the client to hide the dynamic configuration download port.

[0090] In practical applications, the DPD port is only used during DPD activation and deactivation; that is, there is no need for the DPD port to remain in a long enumeration state. Therefore, in this application, after the wireless wide area network (WAN) module is powered on, the eSIM card can be dynamically configured via activation or deactivation requests from the client. After the WAN module's dynamic configuration download port is activated or deactivated, the host communicates with the WAN module to disable the dynamic configuration download port and control the client to hide it. In this way, this application can change the long enumeration state of the DPD port to a dynamic enumeration state, satisfying dynamic configuration download while reducing security risks and power consumption.

[0102] The host computer responds with a command-formatted message and sends the command-formatted message to the wireless wide area network module to dynamically download the eSIM card configuration.
