SUBSCRIBER IDENTITY SYSTEMS, SERVERS, METHODS FOR CONTROLLING A SUBSCRIBER IDENTITY SYSTEM, AND METHODS FOR CONTROLLING A SERVER

1 . A subscriber identity system comprising:

at least one Virtual SIM Host;

a memory configured to store an authorization certificate;

a transmitter configured to transmit to a server a request for Virtual SIM Essence,

the request comprising data based on the authorization certificate;

a receiver configured to receive from the server the Virtual SIM Essence using an asymmetric transmission.

2 . The subscriber identity system of claim 1 , further comprising:

an authorization file receiver configured to receive from another server an authorization file, the authorization file comprising an address of the server, a certificate of the server, and an authorization packet for the server.

3 . The subscriber identity system of claim 2 ,

wherein the request comprises the authorization file.

4 . The subscriber identity system of claim 2 ,

wherein the server comprises a Virtual SIM Essence server, and

wherein the other server comprises an authorization server.

5 . The subscriber identity system of claim 1 ,

the Virtual SIM Host further configured to store an identifier of the VSE.

6 . The subscriber identity system of claim 5 , further comprising:

a de-associating request circuit configured to transmit to the server a request for de-associating the identifier.

7 . The subscriber identity system of claim 1 ,

wherein the Virtual SIM Essence comprises an identifier of the Virtual SIM Essence.

8 . The subscriber identity system of claim 7 , further comprising:

a VSE loading determination circuit configured to determine whether the Virtual SIM Essence may be applied based on the identifier of the Virtual SIM Essence.

9 . A mobile radio communication device, comprising:

the subscriber identity system of claim 1 .

10 . A server comprising:

a memory configured to store Virtual SIM Essence;

a receiver configured to receive from a subscriber identity system a request for the Virtual SIM Essence, the request comprising data based on a certificate;

an authentication circuit configured to evaluate the data based on the certificate; and

a transmitter configured to transmit based on the evaluation of the data based on the certificate to the subscriber identity system the Virtual SIM Essence.

11 . The server of claim 10 ,

the memory further configured to store an association of the Virtual SIM Essence with a subscriber identity system.

12 . The server of claim 11 , further comprising:

a transmission determiner configured to determine whether to transmit the Virtual SIM Essence based on the association.

13 . The server of claim 10 ,

wherein the server comprises a virtual SIM Essence server.

14 . A method for controlling a subscriber identity system, the method comprising:

storing an authorization certificate;

transmitting to a server a request for Virtual SIM Essence, the request comprising data based on the authorization certificate;

receiving from the server the Virtual SIM Essence using an asymmetric transmission.

15 . The method of claim 14 , further comprising:

receiving from another server an authorization file, the authorization file comprising an address of the server, a certificate of the server, and an authorization packet for the server.

16 . The method of claim 15 ,

wherein the request comprises the authorization file.

17 . The method of claim 15 ,

wherein the server comprises a Virtual SIM Essence server, and

wherein the other server comprises an authorization server.

18 . The method of claim 14 , further comprising:

storing an identifier of the Virtual SIM Essence.

19 . The method of claim 18 , further comprising:

transmitting to the server a request for de-associating the identifier.

20 . The method of claim 14 ,

wherein the Virtual SIM Essence comprises an identifier of the Virtual SIM Essence.

21 . The method of claim 20 , further comprising:

determining whether the Virtual SIM Essence may be applied based on the identifier of the Virtual SIM Essence.

22 . A method for controlling a server, the method comprising:

storing Virtual SIM Essences;

receiving from a subscriber identity system a request for the Virtual SIM Essence,

the request comprising data based on a certificate;

evaluating data based on the certificate; and

transmitting based on the evaluation of the data based on the certificate to the subscriber identity system the Virtual SIM Essence.

23 . The method of claim 22 , further comprising:

storing an association of the Virtual SIM Essence with a subscriber identity system.

24 . The method of claim 23 , further comprising:

determining whether to transmit the Virtual SIM Essence based on the association.

25 . The method of claim 22 ,

wherein the server comprises a Virtual SIM Essence server.
