And determining attribute information and downloading type of the Profile to be downloaded according to the version information. And under the condition that the attribute information is master-slave Profile and the download type is download from the Profile, acquiring an independent data template corresponding to the independent data template information. And extracting data of the Profile to be downloaded according to the independent data template. In this way, when the attribute information of the Profile to be downloaded is master-slave Profile and the download type is from Profile, the Profile to be downloaded of the same version information is considered to be non-first download, and the shared data is already stored in the ESIM card. And extracting data from the Profile to be downloaded according to the independent data template, so that the shared data in the Profile to be downloaded can be ignored, and only the independent data can be extracted. Therefore, the file storage space in the ESIM card is saved, and the optimization of the file storage space of the ESIM card is realized.
Further, the ESIM card obtains version information of the Profile to be downloaded and independent data template information, including: the ESIM card searches the publication information and the independent data template information from preset fields of a data structure of the Profile to be downloaded.
In some embodiments, the ESIM card obtains the encapsulated Profile data from the cloud server by the electronic device, parses the encapsulated Profile data, and searches the publication information and the independent data template information from a preset field of Profile header information.
In some embodiments, the preset field is a "profileType attribute" field of "profileHeader PE portability executable Profile header information" in the data structure of the Profile to be downloaded. The contents of the "profileType" field include: "version information" + "independent data template information". The version information is MNO-Profile (Mobile Network Operator-Profile ) version. The MNO-Profile version is used to characterize the relative version number of the ESIM product published by the operator. The independent data template information is a profile independent data template ID (Identity document, identification number).
Further, the ESIM card determines attribute information of the Profile to be downloaded according to the version information, including: and the ESIM card determines the attribute information of the Profile to be downloaded as the general Profile under the condition that the version information is a preset version value or null. And/or determining the attribute information of the Profile to be downloaded as master-slave Profile under the condition that the version information is not a preset version value and the version information is not null.

And determining the download type as downloading from the Profile when the judgment result is that the version information exists in the ESIM card. And/or determining that the download type is the main Profile download if the version information does not exist in the ESIM card as a judgment result. In this way, if the version information exists in the ESIM card as a result of the judgment, the Profile which is the same as the version information is already downloaded in the ESIM card, that is, the Profile to be downloaded of the version information is not downloaded for the first time. And if the judgment result is that the version information does not exist in the ESIM card, the same Profile as the version information is not downloaded in the ESIM card, namely the Profile to be downloaded of the version information is considered to be downloaded for the first time.
In some embodiments, the ESIM card includes a Profile of the first version number, a Profile of the second version number, and a Profile of the third version number, and version information found by the ESIM card from a preset field of a data structure of the Profile to be downloaded is the first version number.

The fourth version number does not exist in the ESIM card and the download type is determined to be the master Profile download.
In some embodiments, the master Profile downloads a Profile for characterizing the same version information as a first download, and the slave Profile downloads a Profile for characterizing the same version information as a non-first download. When the download type of the Profile to be downloaded is the main Profile download, the COS (Card operating system, smart card operating system) of the ESIM card completely downloads and installs the shared data and the independent data in the Profile to be downloaded. When the download type of the Profile to be downloaded is from the Profile, then the COS (Card operating system, smart card operating system) of the ESIM card will only download and install the independent data in the Profile to be downloaded. Therefore, when the profiles of the same operator are downloaded, a large amount of resources can be saved by a master-slave downloading mode.
Further, the master Profile is used for bearing shared data and independent data of all profiles in the same master-slave relationship, and the slave Profile is used for bearing a data starting address of the master Profile and an index of the slave Profile; the shared data are the same data in different ESIM embedded subscriber identity module cards of the same operator, and the independent data are different data in different ESIM cards of the same operator. In some embodiments, the shared data is common data among different ESIM cards of the same operator, which can be updated synchronously without affecting the functionality of each ESIM card. For example, shared data includes file system data, applications, and data packets thereof. The independent data includes personalized data or user data. The independent data includes, for example, data such as ICCID (Integrate circuit card identity, integrated circuit card identification code), IMSI (International Mobile Subscriber Identity, international mobile subscriber identification code), OPC (Originating Party Code, code data issued by an operator for identifying an enterprise or individual initiating communication), key, and the like. The data structures of the generic Profile and the main Profile differ only in the value of the "profileType" field in the "profileHeader PE". The slave Profile has more "master-slave file header mapping tables" than the data storage structures of the generic Profile and the master Profile. The master-slave file header mapping table is used for storing the address of the master Profile and the index of the slave Profile. The index of the slave Profile is used to find the data body address of the current slave Profile.

And/or, in the case that the attribute information is the universal Profile, completely downloading the Profile to be downloaded.
In some embodiments, when the Profile to be downloaded is a slave Profile, a separate data template will be used.
Further, the ESIM card obtains an independent data template corresponding to the independent data template information, including: the ESIM card matches the independent data template corresponding to the independent data template information from a preset storage area. The corresponding relation between the independent data template information and the independent data template is stored in the preset storage area.
In some embodiments, a list of file IDs (Identity document, identification numbers) for a set of independent data is included in the independent data template.
Further, the ESIM card performs data extraction on the Profile to be downloaded according to the independent data template, including: the ESIM card analyzes the Profile to be downloaded to obtain an analysis file. It is determined whether the same file exists in the independent data template as the parsed file. And under the condition that the same file as the analysis file exists in the independent data template, determining the analysis file as independent data, and storing the analysis file.
Further, the independent data template includes a file ID list of the independent data. The ESIM card determines whether the file which is the same as the analysis file exists in the independent data template, and comprises the following steps: the ESIM card obtains the file ID of the analysis file, and determines the analysis file as independent data when the file ID of the independent data identical to the file ID of the analysis file exists in the independent data template. And/or, in the case that the file ID of the independent data identical to the file ID of the analysis file does not exist in the independent data template, determining that the analysis file is shared data.
