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.

Message

Comments

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.
