44.2.4 P-TMSI reallocation
3GPP51.010-1Mobile Station (MS) conformance specificationPart 1: Conformance specificationTS
44.2.4.1 Conformance requirement
1) A Mobile Station shall acknowledge a new P-TMSI when explicitly allocated.
2) The P-TMSI shall be updated on the SIM when the Mobile Station is correctly deactivated in accordance with the manufacturer’s instructions.
3) A Mobile Station shall use the given P-TMSI in further communication with the network.
Reference(s):
3GPP TS 04.08 / 3GPP TS 24.008 subclause 4.7.6.
44.2.4.2 Test Purpose
To verify that the MS is able to receive and acknowledge a new P-TMSI by means of an explicit P-TMSI reallocation procedure.
To verify that the MS has stored the P-TMSI in a non-volatile memory.
The implicit reallocation procedure is tested in the attach procedure.
44.2.4.3 Method of test
Initial conditions
System Simulator:
One cell operating in network operation mode II.
Mobile Station:
The MS has a valid IMSI. MS is Idle Updated.
Specific PICS statements:
– MS operation mode B (TSPC_operation_mode_B).
– MS operation mode C (TSPC_operation_mode_C) (only if mode B not supported).
– Switch off on button (TSPC_Feat_OnOff).
– Automatic GPRS attach procedure at switch on or power on (TSPC_AddInfo_on_auto_GPRS_AP).
PIXIT statements:
–
Test procedure
An explicit P-TMSI reallocation procedure is performed (P-TMSI reallocation command sent from the SS and acknowledged from the MS by P-TMSI reallocation complete). The MS is GPRS detached and switched off. Its power supply is interrupted for 10 s. The power supply is resumed and then the MS is switched on. A GPRS attach procedure is performed with the given P-TMSI as identity.
Maximum duration of test
10 minutes.
