The technical solutions in the embodiments of the present invention will be clearly and completely described below, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
FIG. 1 is a schematic diagram of a profile subscription logical relationship; the method for reusing IMSI in a configuration file of the present invention is shown in the logic relationship diagram of FIG. 1; the configuration file subscription logical relationship diagram includes a resource management platform 10, an eUICC subscription platform 20, and a terminal device 30, where the resource management platform 10 is generally a platform deployed or set by an operator, a virtual operator, or a service provider, and is mainly used for managing a mobile phone number. The resource management platform 10 may be a server (e.g., a cloud server), a smart device, or the like. The resource management platform 10 may communicate with the terminal device 30 (i.e., determine a subscription relationship), for example, the terminal device 30 may enter into a subscription contract with the resource management platform 10 (i.e., an operator), and when the subscription contract is established, obtain a profile (i.e., profile) subscription certificate, where the subscription certificate uniquely corresponds to or determines a profile (i.e., profile) at the eUICC subscription platform 20, and the terminal device 30 may obtain a profile contract code from the resource management platform 10 according to the profile subscription certificate, and may access the eUICC subscription platform 20 by scanning the profile contract code, thereby downloading the corresponding profile (i.e., profile) from the eUICC subscription platform 20. In addition, the resource management platform 10 may communicate with the eUICC subscription platform 20, that is, exchange information, add, generate, refer to a profile (i.e., profile) in the eUICC subscription platform 20, generate a profile contract code, and so on.
Fig. 2 is a schematic flow chart of an embodiment of a method for reusing an IMSI in a configuration file according to the present invention, and as shown in fig. 2, the method for reusing an IMSI in a configuration file disclosed in the embodiment of the present invention mainly includes the following steps:
step S202, receiving the configuration file to be downloaded and the identifier corresponding to the configuration file to be downloaded sent by the resource management platform.
In this implementation, the method for recycling IMSI in the configuration file is written from a single-ended perspective of the eUICC subscription platform. The eUICC is an embedded UICC, which is called an embedded SIM card in the name of chinese, and serves as a secure element carrier, an access authentication module, and a remote configuration capability, and is widely applied to intelligent terminal equipment. The eUICC subscription platform is a management platform of a configuration file (i.e. profile), and can be signed with multiple operators and virtual operators to provide an eUICC remote subscription management service, so that a terminal device can download the profile.
The configuration file to be downloaded refers to a configuration file (namely, profile) which needs to be downloaded by the terminal device, the configuration file is unique in the eUICC subscription platform, the configuration file is determined by a profile subscription certificate, namely, a profile subscription certificate is generated when the terminal device signs a contract with an operator, and the resource management platform can acquire the profile subscription certificate from the eUICC subscription platform, so as to determine the configuration file to be downloaded by the terminal device. Profiles are data profiles of numbers (e.g., cell phone numbers) published by an operator for network access, and generally one Profile represents one number. The Profile contains the IMSI and authentication data corresponding to the IMSI, which are essential data for accessing the number, and only with these data terminal devices can normally make and receive calls and surf the internet, etc. That is, each profile includes a plurality of fields, such as IMSI, KI, OPC, and the like, where IMSI (international mobile subscriber identity) is mainly used for number identification, and one number corresponds to one INSI, that is, one number can be uniquely identified by IMSI. In addition, different profiles may contain the same number data or different number data, that is, different profiles may have the same IMSI or different IMSIs. Referring to fig. 3, each user (i.e., terminal device) corresponds to one profile subscription credential, one profile subscription credential corresponds to one profile in the eUICC subscription platform, one profile has one identifier (ICCID), and multiple profiles may use one same IMSI.
The identifier is information for identifying the configuration files to be downloaded, is mainly used for indexing the configuration files to be downloaded, and is convenient for storing, inquiring and using the configuration files to be downloaded, wherein the identifier is unique, namely one identifier can only be used for identifying one configuration file to be downloaded. The form of the identifier may be various and may be formed of characters, letters, numbers, and the like, alone or in combination.
Alternatively, the identifier may be an ICCID, a Profile ID, and the like.
Step S204, comparing the identifier with the stored identifier in the configuration file database, and comparing the IMSI of the configuration file to be downloaded with the IMSI of the configuration file stored in the configuration file data when the identifier is different from the stored identifier; wherein the stored identifiers correspond one-to-one with the stored configuration files;
step S206, when the IMSI of the configuration file to be downloaded is the same as the IMSI of the stored configuration file, and the stored configuration file is in an idle state, setting the stored configuration file to be in a non-subscription state, and generating a configuration file contract code according to the configuration file to be downloaded and the identifier; the configuration file contract code is used for instructing the terminal equipment to download the corresponding configuration file.
The configuration file database is used for storing profiles and identifiers corresponding to the profiles, and the identifiers are recorded as stored configuration files and stored identifiers respectively. The eCUUI subscription platform compares the received identifier with the stored identifier, and when the identifier is the same as the stored identifier, the eCUUI subscription platform indicates that the configuration file to be downloaded is the same as the stored configuration file, namely the configuration file to be downloaded is the same as the configuration file stored in the configuration file database, and the configuration file to be downloaded cannot be added to the configuration file database. When the identifier is different from the stored identifier, the identifier indicates that the configuration file to be downloaded is different from the configuration file stored in the configuration file database, then the IMSI of the configuration file to be downloaded is compared with the IMSI of the stored configuration file, when the same IMSI exists, the same IMSI needs to be reused, then whether the stored configuration file is in an idle state is judged, if the stored configuration file is in the idle state, the stored configuration file is used by no user (namely terminal equipment), and then the stored configuration file is set to be in an unsubscribable state, so that the situation that the user using the stored configuration file originally downloads the stored configuration file again is avoided, and the situation that the same MISI is used by different users in the same time period is avoided. After the setting is completed, generating a configuration file contract code according to the configuration file to be downloaded and the identifier, wherein the configuration file contract code is corresponding to the subscription certificate and is used for recording the relevant information of the configuration file to be downloaded in the record, such as the identifier, the storage position, the downloading path and the like.
In addition, the form of the profile contract Code may be various, such as a two-dimensional Code (i.e., QR Code), a barcode or a link, etc.
Further, the stored profile being in an idle state may be the stored profile being in a "Delete" state, i.e. the user using the stored profile has deleted the file from the terminal device. Wherein the status is not unique as long as it can be determined that the terminal device is no longer using the stored profile.
Firstly, an eUICC subscription platform receives a configuration file to be downloaded and an identifier of the configuration file to be downloaded sent by a resource management platform, compares the identifier with a stored identifier, if the identifier is different from the stored identifier, then compares the IMSI of the configuration file to be downloaded with the IMSI of the stored configuration file, if the identifier is the same as the stored identifier and the stored configuration file is in an idle state, sets the stored configuration file to be in a non-subscription state, then generates a configuration file contract code of a subscription certificate according to the configuration file to be downloaded and the identifier, sends the configuration file contract code to a resource management platform, the resource management platform sends the configuration file contract code to terminal equipment, and the terminal equipment can download the corresponding configuration file by scanning the configuration file contract code, thereby completing related setting communication. The method can realize the reuse of the IMSI through simple operation, and can effectively ensure that only one terminal device can use the IMSI in the same time period, thereby avoiding communication confusion or communication incapability caused by the simultaneous use of the same IMSI by different terminal devices.
In one embodiment, further comprising: and when the IMSI of the configuration file to be downloaded is different from the IMSI of the stored configuration file, generating a configuration file contract code according to the configuration file to be downloaded and the identifier.
In this implementation, the method for recycling IMSI in the configuration file is written from a single-ended perspective of the eUICC subscription platform. Specifically, when the IMSI of the configuration file to be downloaded is different from the stored IMSI of the configuration file, it indicates that the configuration file to be downloaded is not used, and therefore, the configuration file contract code is directly generated according to the configuration file to be downloaded and the identifier. By adopting the method, the configuration file contract code can be quickly generated when the IMSI does not need to be repeatedly used, so that the terminal equipment can download the corresponding configuration file.
In one embodiment, before the step of generating the profile contract code according to the profile to be downloaded, the method further includes:
and storing the configuration file to be downloaded and the identifier into a configuration file database.
In this implementation, the method for recycling IMSI in the configuration file is written from a single-ended perspective of the eUICC subscription platform. Specifically, the configuration file to be downloaded and the corresponding identifier are stored in the configuration file database, and the configuration file is added. When a new configuration file needs to be added later, the new configuration file needs to be compared with the configuration file in the configuration file database, and whether the new configuration file can be added is determined according to a comparison result.
In one embodiment, further comprising:
when the identifier is the same as the stored identifier, the reception of the configuration file to be downloaded is stopped.
In this implementation, the method for recycling IMSI in the configuration file is written from a single-ended perspective of the eUICC subscription platform. When the identifier is the same as the stored identifier, it is indicated that the configuration file which is the same as the configuration file to be downloaded already exists in the eUICC subscription platform, and at this time, the reception of the configuration file to be downloaded is stopped, so that no repeated configuration file exists in the eUICC subscription platform, the possibility that a plurality of terminal devices repeatedly use the configuration file is further avoided, and further, the communication confusion of the plurality of terminal devices is avoided.
In one embodiment, further comprising: and when the IMSI of the configuration file to be downloaded is the same as the IMSI of the stored configuration file, and the stored configuration file is in a non-idle state, stopping receiving the configuration file to be downloaded.
In this implementation, the method for recycling IMSI in the configuration file is written from a single-ended perspective of the eUICC subscription platform. The IMSI of the configuration file to be downloaded is the same as the IMSI of the stored configuration file, which indicates that the same IMSI needs to be reused, and then whether the stored configuration file is in an idle state is judged, if the stored configuration file is not in the idle state, which indicates that a user (namely terminal equipment) uses the stored configuration file, the receiving of the configuration file to be downloaded is stopped, so that the terminal equipment is prevented from downloading and using the configuration file to be downloaded when other terminal equipment uses the stored configuration file, and the same MISI is prevented from being used by different users in the same time period.
In one embodiment, further comprising:
and sending a transmission key to the resource management platform, wherein the transmission key is used for encrypting the configuration file to be downloaded.
In this implementation, the method for recycling IMSI in the configuration file is written from a single-ended perspective of the eUICC subscription platform. In order to ensure the security and reliability of data transmission, the configuration file to be downloaded and the identifier need to be encrypted on the resource management platform. In the encryption process, a specific key is usually adopted to encrypt the eUICC subscription platform, wherein the specific key is sent by the eUICC subscription platform. The method comprises the following specific steps: referring to fig. 4, the eUICC subscription platform includes a data processing module and an encryptor, where the encryptor may generate a data transmission protection root key (i.e., trans _ key), and allocate a dedicated KCV (i.e., dispersion factor) to each resource management platform, where the dispersion factor may disperse the transmission data protection key to obtain a transmission key, and then send the transmission key to the resource management platform, and the resource management platform may encrypt the configuration file to be downloaded and the identifier with the transmission key. In addition, the data processing module decrypts the received encrypted downloaded configuration file and identifier, and stores the decrypted configuration file and identifier in the configuration file database. In addition, a dispersion algorithm, such as TDES-ECB, AES algorithm, etc., is generally used in dispersing the transmission data protection key using the dispersion factor. By adopting the method, the safety of data transmission can be ensured.
