Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of Internet of Things, and particularly relates to a configuration file downloading method and device. BACKGROUND

[0002] The embedded subscriber identification module (eSIM) has become a very mature technology. At present, the eSIM has been widely applied in the field of Internet of Things. The configuration file downloading in the eSIM configuration process is a key step for enabling the eSIM device to support eSIM network access.

[0003] At present, the commonly used configuration file downloading is dependent on connecting a mobile phone or a personal computer (PC) through Bluetooth or wireless fidelity (WIFI), and then using the network of the mobile phone or the PC to access the server of an operator to download the configuration file. This configuration file downloading method is unstable due to the transmission of Bluetooth or WIFI, which leads to low downloading efficiency, and can only be applied to devices with Bluetooth or WIFI function, and the application range is limited. SUMMARY

[0004] The present application provides a configuration file downloading method and device, which is beneficial to improve the downloading efficiency of the configuration file and is widely applied in various devices.

[0005] In a first aspect, the present application provides a configuration file downloading method applied to an embedded subscriber identification module, the embedded subscriber identification module being connected to a data transmission module through a data transmission serial port. The method comprises the following steps: receiving a configuration file downloading instruction sent by the data transmission module; sending identity information data and a server address to the data transmission module through the data transmission serial port; receiving a communication verification instruction sent by the data transmission module; sending a communication character to the data transmission module, the communication character being used to detect whether the communication with the data transmission module is possible; and receiving a first configuration file sent by the data transmission module through the data transmission serial port, the first configuration file being sent to the data transmission module by an operator server.

[0006] The first configuration file is obtained by the transmission module in the device, and then sent to the embedded subscriber identification module through the data transmission serial port without the help of other devices through Bluetooth or WIFI. The transmission process is stable and the transmission efficiency is high. Moreover, the method is also applicable to devices without Bluetooth communication function.

[0007] In a possible implementation, the method further includes: receiving a configuration file query instruction sent by the data transmission module; querying the first configuration file cluster, and sending the first configuration file cluster to the data transmission module, the configuration file cluster including all available configuration files; if a configuration file enabling instruction sent by the data transmission module is received, enabling the first configuration file, the configuration file enabling instruction including a string used for indicating the first configuration file.

[0008] By sending the first configuration file cluster to the data transmission module, whether the embedded user identity recognition card successfully downloads the configuration file is determined by the data transmission module according to the number of configuration files in the first configuration file cluster. This makes it possible to quickly and efficiently determine whether the configuration file is successfully downloaded, avoiding the situation that no available configuration file is found when the configuration file is enabled subsequently.

[0009] In a possible implementation, after the first configuration file is enabled, the method further includes: receiving a first configuration file update instruction sent by the data transmission module; sending a configuration file update request to the operator server; receiving response data sent by the operator server, the response data including a second configuration file; sending a download success message to the data transmission module, the download success message being used to inform the data transmission module that the second configuration file is successfully downloaded; receiving a configuration file query instruction sent by the data transmission module; querying a second configuration file cluster, and sending the second configuration file cluster to the data transmission module; and if a second configuration file update instruction sent by the data transmission module is received, updating the enabled configuration file to the second configuration file.

[0010] In the updating process, the embedded user identity recognition card has already downloaded the configuration file and has the communication capability with the operator server, so that after receiving the update instruction sent by the data transmission module, the new configuration file is directly downloaded from the operator server, without the need of being transferred by the data transmission module, thereby improving the updating efficiency.

[0011] In a possible implementation, if the second configuration file update instruction sent by the data transmission module is received, the configuration file is updated to the second configuration file, including: if a first configuration file disabling instruction sent by the data transmission module is received, disabling the first configuration file, the first configuration file disabling instruction including a string used for indicating the first configuration file, the first configuration file being the currently enabled configuration file; sending a disabling success message to the data transmission module; and if a configuration file enabling instruction sent by the data transmission module is received, enabling the second configuration file, the configuration file enabling instruction including a string used for indicating the second configuration file.

[0012] The currently used configuration file is disabled before a new configuration file is enabled, thereby avoiding the situation that two configuration files are enabled at the same time, which causes the embedded user identity recognition card to be unable to access the external network.

[0013] In a possible implementation, the method further includes: receiving a second configuration file deactivation instruction sent by the data transmission module, deactivating the first configuration file, the second configuration file deactivation instruction including a string for indicating the first configuration file, and the first configuration file being a currently activated configuration file; sending a deactivation success message to the data transmission module; receiving a configuration file deletion instruction sent by the data transmission module, and deleting the first configuration file, the configuration file deletion instruction including a string for indicating the first configuration file; sending a deletion success message to the data transmission module; and receiving a first notification instruction sent by the data transmission module, and sending identity information data and a server address to the data transmission module.

[0014] After deactivating the currently used configuration file, the configuration file needs to be deleted from the embedded user identity identification card and the operator server, thereby releasing more space.

[0015] In a second aspect, the present application provides a configuration file downloading method, applied to a data transmission module, the data transmission module being connected with an embedded user identity identification card, the method including: sending a configuration file downloading instruction to the embedded user identity identification card; receiving identity information data and a server address sent by the embedded user identity identification card; sending a hypertext transfer protocol request to an operator server based on the server address and the identity information data, the hypertext transfer protocol request being used to request the configuration file from the operator server; receiving and buffering response data sent by the operator server, the response data including a first configuration file; sending a communication verification instruction to the embedded user identity identification card; and if a communication character sent by the embedded user identity identification card is received, sending the first configuration file to the embedded user identity identification card, the communication character being used to detect whether communication with the embedded user identity identification card is possible.

[0016] In a possible implementation, the method further includes: sending a configuration file query instruction to the embedded user identity identification card, the configuration file query instruction being used to instruct the embedded user identity identification card to query all available configuration files; receiving a first configuration file cluster sent by the embedded user identity identification card, the configuration file cluster including all available configuration files; and if the number of configuration files in the first configuration file cluster is greater than one, sending a configuration file activation instruction to the embedded user identity identification card, the configuration file activation instruction including a string for indicating the first configuration file.

[0017] In a possible implementation, the first profile update instruction is sent to the embedded user identity identification card, the first profile update instruction is used to instruct the embedded user identity identification card to download a second profile from the operator server, the second profile is a profile different from the first profile; a download success message sent by the embedded user identity identification card is received; a profile query instruction is sent to the embedded user identity identification card; a second profile cluster sent by the embedded user identity identification card is received; if the number of profiles in the second profile cluster is greater than one, a second profile update instruction is sent to the embedded user identity identification card, the second profile update instruction is used to instruct the embedded user identity identification card to update a currently enabled profile to the second profile.

[0018] In a possible implementation, if the number of profiles in the profile cluster is greater than one, a second profile update instruction is sent to the embedded user identity identification card, including: if the number of profiles in the profile cluster is greater than one, a first profile disable instruction is sent to the embedded user identity identification card, the first profile disable instruction is used to instruct the embedded user identity identification card to disable the first profile, the first profile disable instruction includes a string used to indicate the first profile, the first profile being a currently used profile; if a disable success message sent by the embedded user identity identification card is received, a profile enable instruction is sent to the embedded user identity identification card, the profile enable instruction is used to instruct the profile enable instruction to enable a profile newly downloaded from the operator server.

[0019] In a possible implementation, the method further includes: sending a second profile disable instruction to the embedded user identity identification card, the second profile disable instruction is used to instruct the embedded user identity identification card to disable the first profile, the first profile being a currently enabled profile of the embedded user identity identification card, the second profile disable instruction including a string used to indicate the first profile; receiving a disable success message sent by the embedded user identity identification card; sending a profile deletion instruction to the embedded user identity identification card, the profile deletion instruction is used to instruct the embedded user identity identification card to delete the first profile, the profile deletion instruction including a string used to indicate the first profile; receiving a deletion success message sent by the embedded user identity identification card; sending a first notification instruction to the embedded user identity identification card; obtaining identity information data and a server address sent by the embedded user identity identification card; sending a second notification instruction to the operator server based on the identity information data and the server address, the second notification instruction being used to inform the operator server to delete a profile corresponding to the embedded user identity identification card.

[0035] In order to facilitate understanding of the scheme provided by the embodiments of the present application, some professional terms related to the present application will be introduced first as follows:

[0036] I. Embedded user identity identification card

[0037] An embedded user identity identification card (eSIM) supports remote configuration of SIM card data through the air. The eSIM card directly embeds a traditional SIM card into a device chip instead of adding the SIM card to the device as an independent removable component. A user does not need to insert a physical SIM card, so that the SIM card data can be dynamically and remotely downloaded, the user can actively trigger the download / management of the card data, or dynamically change the card data, flexibly select a subscription operator, or change the operator at any time without unlocking the device or purchasing a new device. In addition, the eSIM is usually small in physical size and can be directly packaged on a communication module, saving hardware space, adapting to harsh working environments, having a long service life, and effectively ensuring the stability of mobile communication and the safety of the device.

[0038] The eSIM has a wide and important application in the Internet of Things field, for example, the in-vehicle device is built-in with the eSIM and configured with the subscription operator data to meet the networking service demand in the vehicle. When the vehicle is sold to another country, the local operator can be remotely configured to replace it. For another example, the watch, bracelet, tablet, notebook and other devices are built-in with the eSIM, which can simplify the device size and facilitate the user to freely select / replace the operator.

[0041] Please refer to Figure 1 , Figure 1 is a system architecture schematic diagram of a configuration file downloading method provided by an embodiment of the present application. The configuration file downloading method provided by the embodiment of the present application can be applied to the system architecture shown in Figure 1 . As Figure 1As shown in the system architecture schematic diagram, the system architecture schematic diagram includes an operator server 100 and a terminal device 101, and the terminal device 101 includes an embedded subscriber identity card 102 and a data transmission module 103. The embedded subscriber identity card 102 and the data transmission module 103 are connected through a serial port.

[0042] Optionally, the operator server 100 can be a stand-alone physical server, a server cluster composed of multiple physical servers, or a distributed system, and can also be a cloud server providing cloud services, cloud databases, cloud computing, cloud functions, cloud storage, network services, cloud communication, middleware services, domain name services, security services, content delivery networks (CDNs), and basic cloud computing services such as big data and artificial intelligence platforms.

[0043] Optionally, the terminal device 101 can be a smart phone, a tablet computer, a notebook computer, a desktop computer, a smart voice interaction device, a smart home appliance, a smart medical device, a vehicle-mounted terminal, and the like, but is not limited thereto.

[0044] In order to improve the download efficiency of the configuration file, the configuration file download method and device provided by the present application can be widely applied to various devices. The configuration file download method and device provided by the present application are described in detail as follows.

[0045] Please refer to Figure 2 , Figure 2 is a flowchart of a configuration file download method provided by an embodiment of the present application. As Figure 2 described, the flowchart of the configuration file download method includes the following steps 201-205. Figure 2 The method execution subject can be an embedded subscriber identity card and a data transmission module. Alternatively Figure 2 The method execution subject can be a chip in the embedded subscriber identity card and the data transmission module. The present application does not limit the method execution subject uniquely, and the corresponding execution subject can also be any device, chip, or software capable of implementing the method, or a combination thereof. For the convenience of subsequent description, Figure 2 The method execution subject is taken as an example of an embedded subscriber identity card and a data transmission module. Among them:

[0046] 201. The embedded subscriber identity card receives the configuration file download instruction sent by the data transmission module. Correspondingly, the data transmission module sends the configuration file download instruction to the embedded subscriber identity card.

[0047] The configuration file download instruction is used to inform the embedded user identity recognition card to send the identity information data and the server address to the data transmission module, so that the data transmission module downloads the corresponding configuration file from the corresponding operator server.

[0048] In a possible embodiment, after the data transmission module receives the instruction issued by the user, the data transmission module sends the configuration file download instruction to the embedded user identity recognition card. The user can issue the above instruction to the data transmission module by pressing a button on a terminal device to which the terminal data transmission module belongs or by clicking a screen to perform a corresponding operation.

[0049] Optionally, the configuration file download instruction can be an AT instruction, which is applied to the connection and communication between the terminal device and the application. Only one AT instruction can be included in each AT command line. For example, the configuration file download instruction can be: AT+LPA=“DOWNLOAD”, <Lpa_add>, <ipa_type>, <action_code>, where the <Lpa_add> parameter represents the address where the LPA is located, the <ipa_type> parameter represents whether the download is performed by an external data transmission module or by a built-in data transmission module, and the <action_code> parameter is used to activate the configuration file.

[0050] 202. The embedded user identity recognition card sends the identity information data and the server address to the data transmission module through the data transmission serial port. Correspondingly, the data transmission module receives the identity information data and the server address sent by the embedded user identity recognition card; sends a HyperText Transfer Protocol (HTTP) request to the operator server based on the server address and the identity information data, the HTTP request being used to request the configuration file from the operator server; and receives and caches the response data sent by the operator server, the response data including the first configuration file.

[0051] The identity information data is the identity information of the embedded user identity recognition card. Understandably, the identity information of the embedded user identity recognition card in different terminal devices is different. The identity information data is used to subsequently request a configuration file from the operator server, and the server address is the address of the operator server in the subsequent process. After the data transmission module sends the HTTP request to the operator server, the response data is received, and the HTTP header in the response data is removed and cached.

[0052] 203. The embedded user identity recognition card receives the communication verification instruction sent by the data transmission module.

[0053] The communication verification instruction is an AT instruction, and can be specifically AT+LPARESP.

[0054] 204. The embedded user identity identification card sends a communication character to the data transmission module, and the communication character is used to detect whether communication with the data transmission module is possible.

[0055] When the data transmission module detects the communication character, it means that communication between the embedded user identity identification card and the data transmission module is possible. In a possible implementation, the communication character can be a right bracket.

[0056] 205. The embedded user identity identification card receives a first configuration file sent by the data transmission module through the data transmission serial port, and the first configuration file is sent to the data transmission module by an operator server.

[0057] The first configuration file is obtained by the data transmission module from the operator server, and the first configuration file can enable a terminal device to which the embedded user identity identification card belongs to have functions such as making a call, surfing the Internet, and sending a message.

[0058] The above describes the download process of the configuration file in detail, and after the download is completed, the first configuration file needs to be enabled, so that the terminal device to which the user identity identification card belongs has functions such as making a call, surfing the Internet, and sending a message. The enabling stage of the first configuration file is further explained below.

[0059] In a possible embodiment, the embedded user identity identification card receives a configuration file query instruction sent by the data transmission module; queries a first configuration file cluster and sends the first configuration file cluster to the data transmission module, the configuration file cluster including all available configuration files; if the embedded user identity identification card receives a configuration file enabling instruction sent by the data transmission module, the first configuration file is enabled, and the configuration file enabling instruction includes a string used to indicate the first configuration file. Correspondingly, the data transmission module sends a configuration file query instruction to the embedded user identity identification card, the configuration file query instruction being used to instruct the embedded user identity identification card to query all available configuration files; the data transmission module receives a first configuration file cluster sent by the embedded user identity identification card, the configuration file cluster including all available configuration files; if the number of configuration files in the first configuration file cluster is greater than one, the data transmission module sends a configuration file enabling instruction to the embedded user identity identification card, and the configuration file enabling instruction includes a string used to indicate the first configuration file.

[0060] The profile query instruction is an AT instruction, and the first profile cluster is all available profiles in the embedded user identity card. After the embedded user identity card sends the first profile cluster to the data transmission module, the data transmission module judges whether the embedded user identity card successfully downloads the first profile according to the number of profiles in the first profile cluster. Specifically, if the number of profiles in the first profile cluster is greater than one, it is considered that the embedded user identity card successfully downloads the first profile, that is, in addition to the initial profile, there are other profiles in the first profile cluster, and it is considered that the embedded user identity card successfully downloads the first profile. It should be noted that the first profile cluster can also include the names of all available profiles. The profile enable instruction is also an AT instruction.

[0061] For example, the profile query instruction can be AT+LPA="GetProfilesInfo", and the profile enable instruction can be AT+LPA="EnableProfiles","iccid string","aid string", wherein <iccidstring>Indicates the profile that needs to be enabled in conjunction with <aid string>, that is, <iccid string> and <aidstring>A string for indicating the first configuration file.

[0062] In the process of using the configuration file, it can be required to update the configuration file used by the embedded user identity card or to disable the configuration file used by the embedded user identity card due to the requirement of a scene. The following is combined with Figure 3 The process of updating the configuration file is further explained. Figure 4 The process of disabling the configuration file is further explained.

[0063] Updating the configuration file:

[0064] 301. The embedded user identity card receives the first configuration file update instruction sent by the data transmission module. Correspondingly, the data transmission module sends the first configuration file update instruction to the embedded user identity card, and the first configuration file update instruction is used to instruct the embedded user identity card to download a second configuration file from the operator server, the second configuration file being a configuration file different from the first configuration file.

[0065] The first configuration file update instruction is an AT instruction, the parameters in the first configuration file update instruction being the same as the parameters in the above configuration file download instruction. Exemplarily, the first configuration file update instruction can be AT+LPA="DOWNLOAD", <Lpa_add>, <ipa_type>, <action_code>, wherein the <Lpa_add> parameter represents the address where the LPA is located, the <ipa_type> parameter represents whether the download is performed by the external data transmission module or the built-in data transmission module, and the <action_code> parameter is used to activate the configuration file.

[0066] 302. The embedded user identity card sends a configuration file update request to the operator server.

[0067] Since the embedded user identity card has successfully enabled the first configuration file in the updating process, the embedded user identity card has the capability of accessing the operator server at this time, and therefore the embedded user identity card can directly send a configuration file update request to the operator server. The configuration file update request can be a POST request.

[0068] 303. The embedded user identity card receives response data sent by the operator server, the response data including the second configuration file.

[0069] The response data returned by the operator server includes the second configuration file and an HTTP header, and the embedded user identity card needs to remove the HTTP header after receiving the response data. The second configuration file is a configuration file different from the first configuration file.

[0070] 304、The embedded user identity recognition card sends a download success message to the data transmission module, and the download success message is used to inform the data transmission module that the second configuration file is downloaded successfully. Correspondingly, the data transmission module receives the download success message sent by the embedded user identity recognition card.

[0071] The download success message can be +LPA: Download Success.

[0072] 305、The embedded user identity recognition card receives the configuration file query instruction sent by the data transmission module. Correspondingly, the data transmission module sends the configuration file query instruction to the embedded user identity recognition card.

[0073] The step can refer to the description in the configuration file enabling process, and will not be described here.

[0074] 306、The embedded user identity recognition card queries the second configuration file cluster and sends the second configuration file cluster to the data transmission module. Correspondingly, the data transmission module receives the second configuration file cluster sent by the embedded user identity recognition card.

[0075] The step can refer to the description in the configuration file enabling process, and will not be described here.

[0076] 307、If the embedded user identity recognition card receives the second configuration file update instruction sent by the data transmission module, the enabled configuration file is updated to the second configuration file. Correspondingly, if the number of configuration files in the second configuration file cluster is greater than one, the data transmission module sends the second configuration file update instruction to the embedded user identity recognition card, and the second configuration file update instruction is used to instruct the embedded user identity recognition card to update the currently enabled configuration file to the second configuration file.

[0077] When the data transmission module judges that the embedded user identity recognition card successfully downloads the second configuration file, the data transmission module sends the second configuration file update instruction to the embedded user identity recognition card, so that the configuration file used by the embedded user identity recognition card is updated to the second configuration file. It should be noted that the first configuration file update instruction and the second configuration file update instruction are different. The first configuration file update instruction is sent by the data transmission module to the embedded user identity recognition card, and instructs the embedded user identity recognition card to download the second configuration file from the operator server. The second configuration file update instruction is sent by the data transmission module to the embedded user identity recognition card, and instructs the embedded user identity recognition card to update the configuration file to the newly downloaded second configuration file.

[0078] In a possible embodiment, if the embedded user identity recognition card receives the second profile update instruction sent by the data transmission module, the profile is updated to the second profile, specifically: if the embedded user identity recognition card receives the first profile deactivation instruction sent by the data transmission module, the first profile is deactivated, the first profile deactivation instruction includes a string for indicating the first profile, and the first profile is the currently enabled profile; the embedded user identity recognition card sends a deactivation success message to the data transmission module; if the embedded user identity recognition card receives the profile activation instruction sent by the data transmission module, the second profile is activated, and the profile activation instruction includes a string for indicating the second profile. Accordingly, if the number of profiles in the profile cluster is greater than one, the data transmission module sends the second profile update instruction to the embedded user identity recognition card, specifically: if the number of profiles in the profile cluster is greater than one, the data transmission module sends the first profile deactivation instruction to the embedded user identity recognition card, the first profile deactivation instruction is used to instruct the embedded user identity recognition card to deactivate the first profile, the first profile deactivation instruction includes a string for indicating the first profile, and the first profile is the currently used profile; if the data transmission module receives the deactivation success message sent by the embedded user identity recognition card, the data transmission module sends the profile activation instruction to the embedded user identity recognition card, and the profile activation instruction is used to instruct the profile activation instruction to activate the latest profile downloaded from the operator server.

[0079] wherein the first profile deactivation instruction is an AT instruction, and an example of the first profile deactivation instruction can be as follows: AT+LPA="DisableProfiles", "<iccid string>", "<aid string>", wherein <iccidstring>Indicates the profile that needs to be deactivated in combination with <aid string>, that is, <iccid string> and <aidstring>String indicating the first profile. The profile enabling instruction can refer to the description in the above-mentioned enabling profile process, which will not be repeated here.

[0080] Disabling the profile:

[0081] 401、The embedded user identity recognition card receives the second profile disabling instruction sent by the data transmission module, and disables the first profile. The second profile disabling instruction includes a string indicating the first profile, and the first profile is the currently enabled profile. Correspondingly, the data transmission module sends the second profile disabling instruction to the embedded user identity recognition card, and the second profile disabling instruction is used to instruct the embedded user identity recognition card to disable the first profile. The first profile is the currently enabled profile of the embedded user identity recognition card, and the second profile disabling instruction includes a string indicating the first profile.

[0082] The second profile disabling instruction can refer to the description of the first profile disabling instruction in the above-mentioned updating profile process. It should be noted that the second profile disabling instruction is used to instruct the embedded user identity recognition card to disable the currently enabled profile.

[0083] 402、The embedded user identity recognition card sends a disabling success message to the data transmission module. Correspondingly, the data transmission module receives the disabling success message sent by the embedded user identity recognition card.

[0084] The disabling success message can refer to the description in the above-mentioned updating profile process, which will not be repeated here.

[0085] 403、The embedded user identity recognition card receives the profile deletion instruction sent by the data transmission module, and then deletes the first profile.
