13.1 UICC interface in PSM handling for E-UTRAN – No UICC deactivation in PSM

13.1.1 Definition and applicability

PSM is intended for UEs that are expecting only infrequent mobile originating and terminating services and that can accept a corresponding latency in the mobile terminating communication. In order to reduce power consumption while in PSM, and only in case the PIN of the USIM is disabled, the ME may optionally deactivate the UICC after entering the PSM.

13.1.2 Conformance requirement

In order to reduce power consumption while the ME is in PSM, and only in case the PIN of the USIM is disabled, the ME may optionally deactivate the UICC (as specified in clause 6A.1 of 3GPP TS 31.101 [39]) after entering the PSM.

Reference:

– TS 31.102 [4], clause 5.1.10;

– TS 24.301 [26], clauses 5.3.5 and 5.3.11.

– TS 31.101 [39], clause 6A.1.

13.1.3 Test purpose

1) To verify that UE does not deactivate the UICC in case the PIN for the USIM is enabled and verified.
