METHOD AND SYSTEM FOR PROVIDING COMMUNICATION SERVICES USING A PLURALITY OF REMOTE SUBSCRIBER IDENTITY MODULES

Abstract

A method and a wireless communication device for providing communication service to devices connected to the wireless communication device. By establishing a starter wireless carrier connection using a starter SIM from a plurality of local SIMs, the wireless communication device establishes one or more logical data connections with one or more SIM banks. Remote-SIMs are selected from the one or more SIM banks and used to establish further wireless carrier connections to allow communication service to be provided to the devices over wireless carrier connections.

Description

Claims

1. A method for replacing wireless carrier connections at a wireless communication device, comprising: (a) establishing a wireless carrier connection with one of wireless carrier networks by using a remote SIM from a SIM bank;(b) monitoring at least one condition associated with the remote SIM; and (c) when the at least one condition associated with the remote SIM is not satisfied: (i) if at least one different wireless carrier connection is capable of being used to communicate with the SIM bank, stopping usage of the remote SIM;(ii) selecting a replacement SIM;(iii) establishing a replacement wireless carrier connection using the replacement SIM; and(iv) starting to use the replacement wireless carrier connection.

2. The method of claim 1, wherein the wireless carrier connection is to be maintained if no other wireless carrier connections are capable of being used to communicate with the SIM bank.

3. The method of claim 1, wherein the replacement SIM is selected based on a SIM selection policy.

4. The method of claim 3, wherein the SIM selection policy is based on one or more of the following: position of a SIM placed in the wireless communication device, a SIM category, network performance history of a SIM and identity of wireless carrier network issuing a SIM.

5. The method of claim 1, wherein the at least one condition is selected from one or more of the following: packet drop rate of the wireless carrier connection, amount of data usage of the remote SIM, quality of the wireless carrier network, and coverage of the wireless carrier network.

6. The method of claim 1, wherein the remote SIM is a foreign SIM.

7. The method of claim 1, wherein the remote SIM is an embedded Universal Integrated Circuit Card (eUICC).

8. The method of claim 1, wherein the replacement SIM is a foreign SIM.

9. The method of claim 1, wherein the replacement SIM is an eUICC.

10. The method of claim 1, further comprising: establishing an aggregated logical data connection over the replacementwireless carrier connection.

11. A wireless communication device, comprising: at least one processing unit;at least one main memory;at least one logic circuit to perform multiplexing;a plurality of wireless communication modules;at least one SIM card interface; andat least one storage medium comprising program instructions executable by the at least one processing unit for: (a) establishing a wireless carrier connection with one of wireless carrier networks by using a remote SIM from a SIM bank;(b) monitoring at least one condition associated with the remote SIM; and (c) when the at least one condition associated with the remote SIM is not satisfied: (i) if at least one different wireless carrier connection is capable of being used to communicate with the SIM bank, stopping usage of the remote SIM;(ii) selecting a replacement SIM;(iii) establishing a replacement wireless carrier connection using the replacement SIM; and(iv) starting to use the replacement wireless carrier connection.

12. The wireless communication device of claim 11, wherein the wireless carrier connection is to be maintained if no other wireless carrier connections are capable of being used to communicate with the SIM bank.

13. The wireless communication device of claim 11, wherein the replacement SIM is selected based on a SIM selection policy.

14. The wireless communication device of claim 13, wherein the SIM selection policy is based on one or more of the following: position of a SIM placed in the wireless communication device, a SIM category, network performance history of a SIM and identity of wireless carrier network issuing a SIM.

15. The wireless communication device of claim 11, wherein the at least one condition is selected from one or more of the following: packet drop rate of the wireless carrier connection, amount of data usage of the remote SIM, quality of the wireless carrier network, and coverage of the wireless carrier network.

16. The wireless communication device of claim 11, wherein the remote SIM is a foreign SIM.

17. The wireless communication device of claim 11, wherein the remote SIM is an embedded Universal Integrated Circuit Card (eUICC).

18. The wireless communication device of claim 11, wherein the replacement SIM is a foreign SIM.

19. The wireless communication device of claim 11, wherein the replacement SIM is an eUICC.

20. The wireless communication device of claim 11, wherein the at least one storage medium further comprises program instructions executable by the at least one processing unit for: establishing an aggregated logical data connection over the replacement wireless carrier connection.
