otherwise the SMS should not be processed further. |

The SIM applet registers a timer with min_sleep_time from the SMS. When the |
| 216 |
timer triggers, the IMSI of the SIM is overwritten with the new pseudonymous |
|
| 217 |
IMSI, the TMSI and GSM Ciphering key Kc (3GPP TS 31.102, Section 4.4.3.1) are |
|
| 218 |
invalidated. The current imsi_pseudo_i from the SMS is stored in the SIM applet |
|
| 216 |
timer triggers, EF~IMSI~ of the SIM is overwritten with the new pseudonymous |
|
| 217 |
IMSI. The TMSI and related data (EF~LOCI~, EF~PSLOCI~) and ciphering keys |
|
| 218 |
(EF~Kc~, EF~KcGPRS~, EF~Keys~, EF~KeysPS~) are invalidated (see 3GPP TS |
|
| 219 |
31.102). The current imsi_pseudo_i from the SMS is stored in the SIM applet |
|
| 219 | 220 |
to compare it with the next SMS. imsi_pseudo_lu is reset to 0. Afterwards, |
| 220 | 221 |
the EF~IMSI~ changing procedure in 3GPP TS 11.14, Section 6.4.7.1 is executed |
| 221 | 222 |
to apply the new IMSI. |
