44.2.6 Identification procedure
3GPP51.010-1Mobile Station (MS) conformance specificationPart 1: Conformance specificationTS
The purpose of this procedure is to check that the MS gives its identity as requested by the network. If this procedure does not work, it will not be possible for the network to rely on the identity claimed by the MS.
44.2.6.1 General Identification
44.2.6.1.1 Conformance requirement
1) When requested by the network the Mobile Station shall send its IMSI.
2) When requested by the network the Mobile Station shall send its IMEI as stored in the Mobile Equipment.
3) When requested by the network the Mobile Station shall send its IMEISV as stored in the Mobile Equipment.
Reference(s):
3GPP TS 04.08 / 3GPP TS 24.008 subclauses 4.7.8.
44.2.6.1.2 Test purpose
To verify that the MS sends identity information as requested by the system. The following identities can be requested: IMSI, IMEI and IMEISV.
44.2.6.1.3 Method of test
Initial conditions
System Simulator:
One cell operating in network 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).
– 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
The SS requests identity information from the MS:
– IMSI;
– IMEI;
– IMEISV.
Maximum duration of test
10 minutes.

1 |
SS |
The MS is set in MS operation mode C (see PICS). If MS operation mode C not supported, goto step 14. |
|
2 |
MS |
The MS is powered up or switched on and initiates an attach (see PICS). |
|
3 |
MS -> SS |
ATTACH REQUEST |
Attach type = ‘GPRS attach’ Mobile identity = IMSI |
4 |
SS -> MS |
ATTACH ACCEPT |
Attach result = ‘GPRS only attached’ Mobile identity = P-TMSI-1 P-TMSI-1 signature Routing area identity = RAI-1 |
5 |
MS -> SS |
ATTACH COMPLETE |
|
6 |
SS -> MS |
IDENTITY REQUEST |
Identity type = IMSI |
7 |
MS -> SS |
IDENTITY RESPONSE |
Mobile identity = IMSI |
8 |
SS -> MS |
IDENTITY REQUEST |
Identity type = IMEI |
9 |
MS -> SS |
IDENTITY RESPONSE |
Mobile identity = IMEI |
10 |
SS -> MS |
IDENTITY REQUEST |
Identity type = IMEISV |
11 |
MS -> SS |
IDENTITY RESPONSE |
Mobile identity = IMEISV |
12 |
MS |
The MS is switched off or power is removed (see PICS). |
|
13 |
MS -> SS |
DETACH REQUEST |
Message not sent if power is removed. Detach type = ‘power switched off, GPRS detach’ |
14 |
MS |
The MS is set in MS operation mode B (see PICS) and the test is repeated from step 2 to step 13. |
