Abstract

A method of supporting enhanced SIM replacement procedure is proposed. A UE detects that a first identification module running a first application is inserted. The first identification module belongs to a PLMN, and an enhanced service is provided by an operator of the PLMN via a second application. The UE sends a notification to the operator for obtaining a second identification module. The UE detects that the second identification module running the second application is inserted. The UE sends a second notification to the operator for activating the second identification module such that the UE is able to use the enhanced service provided by the operator. The device-assisted solution for SIM replacement complies with existing security/authentication model, has no standard charge, and complies with existing SIM replacement model and offers a simpler and more automatic procedure.

Claims

1. A method, comprising:

(a) detecting a first identification module running a first application is inserted in a user equipment (UE) by the UE, wherein the first identification module belongs to a Public Land Mobile Network (PLMN);

(b) detecting that the UE is unable to access an enhanced service network provided by an operator of the PLMN via the first application; and

(c) sending a first notification to a network server for obtaining a second application such that the UE can access the enhanced service network of the same PLMN.

2. The method of claim 1, wherein the first application is a Subscriber Identity Module (SIM) application.

3. The method of claim 1, wherein the second application is one of a Universal Subscriber Identity Module (USIM), a remote SIM, a virtual SIM, a smart SIM, an embedded SIM, and profile data for embedded Universal Integrated Circuit Card (eUICC).

4. The method of claim 1, further comprising:

(d) detecting a second identification module running the second application; and

(e) sending a second notification to the network server for activating the second identification module such that the UE is able to use the enhanced service provided by the operator.

5. The method of claim 4, wherein the notifications are sent through one of a short messaging (SMS), unstructured supplementary service data (USSD), a voice call, and IP traffic.

6. The method of claim 4, wherein the sending in (c) and (e) is triggered by prompting a selection menu on a user interface of the UE.

7. The method of claim 4, wherein the UE is inserted with both the first and the second identification modules belong to the same PLMN, and wherein the second notification is sent via the first or the second identification module.

8. The method of claim 4, wherein the activating in (e) involves an Operation Administration and Management (OAM) mechanism in the operator network.

9. The method of claim 4, wherein the activating in (e) involves accessing the second identification module via an Over-the-Air (OTA) mechanism.

10. A method, comprising:

(a) detecting an identification module running an application is inserted in a user equipment (UE), wherein the application is one of a Universal Subscriber Identity Module (USIM), a remote SIM, a virtual SIM, a smart SIM, an embedded SIM, and profile data for embedded Universal Integrated Circuit Card (eUICC);

(b) sending a notification to a network server for activating the identification module; and

(c) performing an activation procedure for activating the identification module such that the UE can access an enhanced service network, wherein the activating involves an Operation Administration and Management (OAM) mechanism in an operator network or accessing the second identification module via an Over-the-Air (OTA) mechanism.

11. The method of claim 10, wherein the UE detects whether the identification module is activated by attaching to the enhanced service network via NAS signaling or making a voice call via the enhanced service network.

12. The method of claim 10, wherein the notification further comprises a request for replacing a previously inserted identification module.

13. The method of claim 10, wherein the UE sends a second notification to an operator for replacing a previously inserted identification module.

14. A user equipment (UE), comprising:

a first identification module running a first application that is inserted in the UE, wherein the first identification module belongs to a Public Land Mobile Network (PLMN), and wherein an enhanced service is provided by an operator of the PLMN via a second application;

a second identification module running the second application is inserted in the UE, wherein the second identification module is activated via an Operation Administration and Management (OAM) mechanism in the operator network or via accessing through an Over-the-Air (OTA) mechanism; and

a notification module that sends a first notification to the operator for obtaining the second identification module, wherein the notification module also sends a second notification to the operator for activating the second identification module such that the UE is able to use the enhanced service provided by the operator.

15. The UE of claim 14, wherein the first application is a Subscriber Identity Module (SIM) application.

16. The UE of claim 14, wherein the second application is one of a Universal Subscriber Identity Module (USIM), a remote SIM, a virtual SIM, a smart SIM, an embedded SIM, and profile data for embedded Universal Integrated Circuit Card (eUICC).

17. The UE of claim 14, wherein the notifications are sent through one of a short messaging (SMS), unstructured supplementary service data (USSD), a voice call, and IP traffic.

18. The UE of claim 14, wherein the UE detects whether the second identification module is activated by making a voice call using the enhanced service.

19. The UE of claim 14, wherein the second notification further comprises a request for replacing the first identification module.

20. The UE of claim 14, wherein the UE sends a third notification to the operator for replacing the first identification module.
