Method and apparatus for managing authentication in wireless communication system while subscriber identity module is not available
First Claim
1. A method for performing, by a mobile equipment running at least one application, an authentication procedure in a wireless communication system, the method comprising:
- detecting whether a universal integrated circuit card (UICC) of the mobile equipment is in a first status or a second status;
when it is detected that the UICC is in the first status or the second status, storing a first set of authentication credentials in the UICC and a second set of authentication credentials in the mobile equipment;
performing a fallback authentication procedure by using one of the first set of authentication credentials or the second set of authentication credentials;
setting a timer upon performing the fallback authentication procedure; and
performing a normal authentication procedure when the timer expires and upon detecting that the UICC is not in the first status or the second status,wherein when UICC processing is busy but the UICC is able to answer a request, the UICC is in the first status, and when the UICC interface is busy such that the UICC is not able to answer a request, the UICC is in the second status,wherein the first set of authentication credentials is used for performing the fallback authentication procedure when the UICC of the mobile equipment is in the first status,wherein the second set of authentication credentials is used for performing the fallback authentication procedure when the UICC of the mobile equipment is in the second status,wherein the first set of authentication credentials has a higher security level than the second set of authentication credentials, andwherein the first set and second set of authentication credentials are pre-calculated.

Abstract
A method and apparatus for performing an authentication procedure in a wireless communication system is provided. A mobile equipment, which runs a plurality of applications, detects that a universal integrated circuit card (UICC) of the mobile equipment is in a first status, in which the UICC is able to answer a request, or a second status, in which the UICC is not able to answer a request. If detected, the mobile equipment stores a first set of authentication credentials in the UICC and a second set of authentication credentials in the mobile equipment, and performs the authentication procedure by using one of the first set of authentication credentials for the first status or the second set of authentication credentials for the second status.

5. A mobile equipment running at least one application comprising:
-
a memory; a transceiver; a universal integrated circuit card (UICC); and a processor, operatively coupled to the memory, the transceiver and the UICC, wherein the processor is configured to; detect whether the UICC is in a first status or a second status; when it is detected that the UICC is in the first status or the second status, store a first set of authentication credentials in the UICC and a second set of authentication credentials in the memory; perform a fallback authentication procedure by using one of the first set of authentication credentials or the second set of authentication credentials; set a timer upon performing the fallback authentication procedure; and perform a normal authentication procedure when the timer expires and upon detecting that the UICC is not in the first status or the second status, wherein when UICC processing is busy but the UICC is able to answer a request, the UICC is in the first status, and when the UICC interface is busy such that the UICC is not able to answer a request, the UICC is in the second status, wherein the first set of authentication credentials is used for performing the fallback authentication procedure when the UICC of the mobile equipment is in the first status, wherein the second set of authentication credentials is used for performing the fallback authentication procedure when the UICC of the mobile equipment is in the second status, wherein the first set of authentication credentials has a higher security level than the second set of authentication credentials, and wherein the first set and second set of authentication credentials are pre-calculated. - View Dependent Claims (6, 7)
