Description

[Technical Field]

[0001] The present invention relates to remote SIM provisioning, i.e. provisioning a Subscriber Identity Module, abbreviated SIM, profile to an eUICC from a remote server, for example according to GSMA specifications SGP.22 or SGP.02. [Background technology]

[0002] The GSMA specification [1] SGP.22 RSP Technical Specification Version 2.2.2 (abbreviated as SGP.22), dated June 5, 2020, in particular Chapter 3.1, entitled "Remote Provisioning," describes remote SIM provisioning by downloading a profile to an embedded Universal Integrated Circuit Card (eUICC) hosted on a device. A device is understood to be a mobile device or mobile terminal, i.e., a device or terminal capable of communicating within a mobile network, i.e., a wireless network. According to Chapter 3.1.1, "Profile Download Initiation," a pre-defined profile already stored in the profile provisioning server SM-DP+ is reserved upon an end-user order from a mobile network operator (MOO). Then, according to Chapter 3.1.2, "Common Mutual Authentication Procedure," a mutual authentication procedure is performed between the profile provisioning server SM-DP+ and the eUICC. Then, according to Chapter 3.1.3, "Profile Download and Installation," the reserved profile is downloaded to the eUICC via the device and installed on the eUICC. In the SGP.22 scheme, the profile provisioning server is called SM-DP+.

[0003] Devices complying with SGP.22 are in particular so-called consumer devices such as, for example, smartphones, smart watches and tablet PCs with mobile network connectivity, and other computers with mobile network connectivity.

[0004] The eUICC architecture is described in SGP.22 Chapter 2.4 "eUICC Architecture" of [1], particularly Figure 3. Each profile is contained in an individual ISD-P, the Issuer Security Domain Profile. Each ISD-P contains one profile. A profile has a primary technical service task: authenticating the eUICC and / or its device and / or its end user to the mobile network with which the profile is associated. An ISD-P or profile can contain additional elements, such as applets and applications. Applets and applications can have service purposes other than authentication to the mobile network, such as payment services or ticketing services. In particular, near field communication (NFC) payment services can be implemented by an NFC payment applet or application within a profile or ISD-P. Currently, applets and applications offered for download to an ISD-P are static and ready-made. The profiles (or content in general) downloaded to the eUICC during a Remote SIM Provisioning session, as described in [1] SGP.22 Chapter 3.1.3 "Profile Download and Installation", are downloaded to the eUICC in the form of a Bounded Profile Package, BPP, which is detailed in [1] SGP.22 Chapter 2.5.4 and in the GSMA specification [3] SGP.21, RSP Architecture, Version 2.2, 1 September 2017. The Bounded Profile Package contains, in order: (1) ISD-P and ISD-P configuration, (2) metadata, (3) profile protection keys, and (4) the actual profile payload in the form of a Protection Profile Package, all in the form of a set of Tag Length Value, TLV commands for installation on the eUICC.

[0005] The GSMA specification [2] SGP.02, Remote Provisioning Architecture for Embedded UICC Technical Specification Version 4.1, dated 5 June 2020, aims to define a technical solution for remote provisioning and management of embedded UICCs (eUICCs) in machine-to-machine devices, also known as M2M devices. According to [2] SGP.02, the download and installation of a profile from a profile server comprises the steps of creating an ISD-P, establishing a key, and downloading and installing the profile.

[0006] The profile data of a profile comprises some individual data that is unique to each profile, such as for example the International Mobile Subscriber Identity number IMSI, the authentication key Ki, and the profile number International Circuit Card IDentifier ICCID.

[0007] Other data is specific to the type of eUICC or device, such as the eUICC-ID or chip hardware number Equipment Identifier, EID (hardware identifier as identified in [2] SGP.02), or a part of the EID, such as a country indicator, or the International Mobile Equipment Identity Number IMEI (mobile equipment = device = mobile terminal), or a part of the IMEI, such as a Type Allocation Code TAC, indicating the type of device.

[0008] Currently, eUICCs and devices are partly standardized and generic, and partly proprietary and unique. In particular, different eUICCs and different devices have different capabilities. For this reason, ready-made profiles, applets, and applications are generally not fully compatible from the start with the target eUICC or / and device, i.e., the eUICC or / and device for which the profile, applet, or application is intended. Instead, adaptation to ready-made profiles, applets, and applications is required once the eUICC type and device type or / and the individual target eUICC and individual target device are known. Currently, such adaptation is often performed after the download by a command sent to the eUICC after the profile, applet, or application has been downloaded and installed. This adaptation can therefore incur additional traffic on the mobile network, additional provisioning time, and potentially additional monetary costs.

[0009] Prior art documents [4] EP2910039B1 and [5] EP2802162A1 each disclose a solution that seeks to reduce the download traffic from the profile server to the eUICC by providing the device or eUICC with profile templates, so that when a new profile is desired, only a partial profile is downloaded from the profile server.

[0010] Prior art document [6] DE102015001815A1 proposes to create a local copy of a profile in the eUICC and further use the copy as a template for a new profile, thus reducing the download traffic from the profile server that is also required for the new profile.

[0011] The above prior art references require that a profile or template already exists on the eUICC to enable download and implementation of a new profile with reduced mobile network traffic between the profile server and the set of devices and eUICCs.

[0012] Prior art document [7] US2020 / 0374686A1 discloses an embedded universal integrated circuit card (eUICC) profile management method for processing two profiles, the method comprising: obtaining first metadata of a first profile of the eUICC; sending a profile obtainment request to a profile server, the profile obtainment request comprising an eUICC identifier, a profile identifier, and an operating system update flag; receiving a second profile from the profile server; installing the second profile on the eUICC; and configuring second metadata of the second profile based on the first metadata.

[0013] Prior art document [8] EP3716656A1 discloses a profile generation and acquisition method. When a first subscriber identity module card in a terminal device is registered with a first service provider, and a user requires a subscription to a second service provider, a second service provider server acquires, from the first service provider server, service registration information used by the first subscriber identity module card to access the first service provider network. The second service provider server generates a second profile for accessing the second service provider network based on the service registration information. The second profile may be generated based on the existing service registration information.

[0014] Prior art document [9] DE102019001840B3 discloses a method for providing a subscription profile to a subscriber identity module (eUICC) using a subscription server. The subscription server has knowledge of a first subscription profile installed in the subscriber identity module. The first subscription profile has a first profile file structure and first profile data stored in the first profile file structure. At least a portion of the second profile file structure of a second subscription profile is marked in the subscription server. The second subscription profile is sent to the subscriber identity module, and the marked portion of the second subscription profile is sent without the second profile data. The missing profile data can be taken over from the first subscription profile already present in the eUICC.

[0015] Prior art document

[10] DE102015001815A1 discloses a subscriber identity module (eUICC) configured to generate a second profile using the file structure of a first profile already installed on the subscriber identity module as a template. A cloning function of the eUICC creates a copy of the profile file structure of the first subscription profile and stores it as the second profile file structure on the subscriber identity module, such that a second profile file structure configured to receive the second profile data is generated.

[0016] Prior art document

[11] US2019 / 0208405A1 discloses an electronic device including an eUICC on which a first profile is installed. The eUICC requests that a second profile be installed on the eUICC from a first server based on the first profile, receives the second profile from a second server associated with the first server, and installs the received second profile on the eUICC. The second profile and the first profile contain the same subscriber identification information, for example, the same telephone number MSISDN.

[0017] Prior art document

[12] US2021 / 0105609A1 discloses a method for enabling further use of a profile contained in a non-removable eUICC hosted on a terminal when replacing it with a different terminal. Here, the profile is detached from the terminal, stored in an intermediate storage, for example a cloud server, and then transferred to the different terminal. Upon detaching the profile, an activation code is generated that can be used to download the profile.

[0018] Prior art document

[13] US2019 / 0174299A1 discloses a method for enabling migration of a subscription from a source device to a destination device. The method comprises receiving, from the source device, confirmation that a first profile associated with the subscription has been deleted on the source device, and securing a second profile associated with the subscription to be provisioned to an eUICC of the destination device. At least one piece of subscription information is the same for the first and second profiles. An activation code is used for use in migrating the subscription to the destination device.

[0047] [Figure 1] The schedule represents up to two different profile images for each of the three users. [Figure 2] Various form factors or eUICC. DETAILED DESCRIPTION OF THE INVENTION

[0048] Figure 1 shows up to two different Profile Image1 shows a schedule representing identifiers of the data generating server. The schedule shows three identifiers U1, U2, and U3 of three users of mobile devices registered with the data generating server. Each of the three users U1, U2, and U3 is assigned a set of global identifiers GI that is unique to the respective user. In the example of FIG. 1 , the set of unique global identifiers GI comprises a profile number ICCID and an authentication key Ki. A first user with identifier U1 is assigned a global identifier set GI with value GI1, comprising a profile number ICCID with value 123456 and an authentication key Ki with value abcde. A second user with identifier U2 is assigned a global identifier set GI with value GI2, comprising a profile number ICCID with value 789012 and an authentication key Ki with value fghij. A third user with identifier U3 is assigned a global identifier set GI with value GI3, comprising a profile number ICCID with value 345678 and an authentication key Ki with value klmno. The identifier values ​​shown are purely symbolic, and actual products will have a format that complies with applicable standards, for example by GSMA and / or ETSI.

[0049] For a first user with identifier U1, a first Profile Image P1(U1) and the second Profile Image P2(U1) is generated and both are assigned the same profile number ICCID, which is the value 123456, and the same authentication key Ki, which is the value abcde. Alternatively, the two profiles are assigned only the same profile number ICCID, which is the value 123456, but have different authentication keys Ki. Profile Image P1(U1) and the second Profile Image P2(U1) differs by a different functional identifier FI, which is Profile Image For P1(U1) we have the value FI=FI1, and for the second Profile ImageFor P2(U1) we have the value FI=FI2. Different function identifiers FI may represent, for example, different mobile devices with different features or different operating systems, etc., or different eUICCs with different features, or a combination of such differences. Also, there may be more function identifiers than the two shown function identifiers FI1 and FI2, i.e. FI3, FI4, etc.

[0050] Similarly, for a second user assigned a user identifier U2, two profiles PI(U2) and P2(U2) are generated in the data generating server and assigned the same profile number ICCID, which is the value 789012, and the same authentication key Ki, which is the value fghij (or the two profiles are assigned only the same profile number ICCID=789012, but with different authentication keys Ki). Profile Image PI(U2) and the second Profile Image P2(U2) differs by a different functional identifier FI, which is Profile Image For PI(U2) we have the value FI=FI1, and the second Profile Image For P2(U2) we have the value FI=FI2.

[0051] For the third user, there is now one ID with profile number ICCID=345678 and global identifier set GI=GI3 with authentication key Ki=klmno. Profile Image Only the data generating server will have the same global identifier set GI=GI3. Profile Image can be generated.

[0052] The set of global identifiers in Figure 1 must comprise at least one global identifier GI, but may comprise two, three, four or even more global identifiers. As an alternative to the example of Figure 1, for example, only the profile number ICCID may be provided as the global identifier GI.

[0053] FIG. 2 shows eUICCs in various form factors: from left to right, a plug-in SIM card, a proper embedded UICC or eUICC, and an integrated UICC or iUICC that is integrated into the chipset of a mobile device.

[0054] The present invention is generally independent of the form factor of the eUICC and is applicable to eUICCs having any of the eUICC form factors shown in FIG. 2, and is also applicable to eUICCs having different form factors.

[0055] The mobile device hosting the eUICC may likewise have a variety of form factors, for example, a smartphone, a smartwatch, a tablet PC, an in-vehicle M2M device, and the like.
