Abstract

The invention relates to a method for providing subscription profiles to a subscriber identity module, preferably an eUICC, by means of a subscription server, preferably an SM-DP, wherein: the subscription server has knowledge of a first subscription profile, which is installed in the subscriber identity module, has a first profile file structure and first profile data stored in the first profile file structure; and at least a portion of a second profile file structure of a second subscription profile is flagged in the subscription server and the second subscription profile is sent to the subscriber identity module, the flagged portion of the second subscription profile being sent without second profile data. The invention additionally relates to a corresponding method in a subscriber identity module, a subscriber identity module, a subscription server and a computer program product.

First claim

The invention claimed is:

1. A method for providing subscription profiles to a subscriber identity module by means of a subscription server,
wherein the subscription server has knowledge of a first subscription profile installed in the subscriber identity module and including a first profile file structure and first profile data stored in the first profile file structure,
wherein the following method steps run in the subscription server:
marking at least a part of a second profile file structure of a second subscription profile; and
transmitting the second subscription profile to the subscriber identity module,
wherein the marked part of the second subscription profile is transmitted without second profile data,
wherein in the transmitting step those first profile data of the first subscription profile, which are to be copied, are indicated to be stored as second profile data into the marked part of the second profile file structure of the second subscription profile.

2. The method according to claim 1 , wherein the method further comprises:
receiving a confirmation from the subscriber identity module that those first profile data have been copied and that the copied first profile data have been stored into the marked part of the second profile file structure of the second subscription profile;
transmitting a profile activating command to the subscriber identity module for activating the second subscription profile.

3. The method according to claim 1 , wherein the method further comprises:
transmitting a deleting command to the subscriber identity module for deleting at least the first profile data of the first subscription profile.

4. The method according to claim 1 , wherein the marked part of the second subscription profile includes at least one of the following elements:
at least one profile elementary file;
a subscriber identifier;
a subscriber identity module identifier;
an authentication key;
an OTA key;
a subscription profile application update; and/or
a subscription profile file update.

5. The method according to claim 1 , wherein the method steps comprise a creating function and/or an activating function and/or a deactivating function according to the technical specification SGP02 remote provisioning architecture for-embedded UICC, version 2.0.

6. A method for managing subscription profiles in a subscriber identity module,
wherein at least one first subscription profile is installed in the subscriber identity module and
wherein the first installed subscription profile comprises a first profile file structure and first profile data stored in the file structure,
wherein the following method steps run in the subscriber identity module:
receiving a second subscription profile including at least partially marked second profile data structure from a subscription server while indicating first profile data of the first subscription profile, which are to be copied and to be stored as second profile data in the second profile file structure of the second subscription profile,
wherein the marked part of the second profile data structure of the second subscription profile has been transmitted from the subscription server without second profile data;
copying the indicated first profile data of the first subscription profile;
storing the copied indicated first profile data into the marked part of the second profile file structure of the second subscription profile to complete the second subscription profile,
wherein the second subscription profile is set up.

7. The method according to claim 6 , wherein the method further comprises:
transmitting a confirmation to the subscription server that the indicated first profile data have been stored into the marked part of the second profile file structure of the second subscription profile,
receiving a profile activating command from the subscription server for activating the second subscription profile; and
activating the second subscription profile while deactivating the first subscription profile.

8. The method according to claim 7 , wherein the method further comprises:
receiving a deleting command from the subscription server for deleting at least the first profile data of the first subscription profile.

9. The method according to claim 6 , wherein the copying of the indicated first profile data and the storing of the copied indicated first profile data into the second profile file structure of the second subscription profile are performed without transmitting data, in particular profile data, between the subscriber identity module and the subscription server.

10. A computer program product, executable installed in a subscriber identity module that executes the method steps according to claim 6 , when the computer program product is executed on the subscriber identity module.

11. A subscriber identity module, set up for or comprising a first subscription profile installed in the subscriber identity module,
wherein the installed first subscription profile comprises a first profile file structure and first profile data stored in the file structure,
wherein a copying and storing function, which is set up, after receiving a second subscription profile including at least partially marked second profile data structure from a subscription server while indicating first profile data of the first subscription profile,
wherein the marked part of the second profile data structure of the second subscription profile has been transmitted from the subscription server without second profile data, to copy the indicated first profile data of the first subscription profile into the marked part of the second profile file structure of the second subscription profile to complete the second subscription profile,
wherein the second subscription profile is set up in the subscriber identity module.

12. The subscriber identity module according to claim 11 , wherein the copying and storing function is implemented by a functionality of the operating system, or, alternatively, by an applet, which is set up to start after receiving the second subscription profile.

13. The subscriber identity module according to claim 11 , further comprising:
a data memory for storing the subscription profiles,
an interface, which is set up for communication with the subscription server;
an interface, which is set up for communication with a network server; and
means, which are set up to perform a method for managing subscription profiles in a subscriber identity module,
wherein at least one first subscription profile is installed in the subscriber identity module and
wherein the first installed subscription profile comprises a first profile file structure and first profile data stored in the file structure,
wherein the following method steps run in the subscriber identity module:
receiving a second subscription profile including at least partially marked second profile data structure from a subscription server while indicating first profile data of the first subscription profile, which are to be copied and to be stored as second profile data in the second profile file structure of the second subscription profile,
wherein the marked part of the second profile data structure of the second subscription profile has been transmitted from the subscription server without second profile data;
copying the indicated first profile data of the first subscription profile;
storing the copied indicated first profile data into the marked part of the second profile file structure of the second subscription profile to complete the second subscription profile,
wherein the second subscription profile is set up.
