27.3 MS identification by long TMSI
3GPP51.010-1Mobile Station (MS) conformance specificationPart 1: Conformance specificationTS
27.3.1 Definition
The TMSI is temporarily used for identification of the MS by a GSM network. It will have been previously assigned by the network. The TMSI is stored in the SIM by the ME and read during the SIM/ME initialization procedure.
27.3.2 Conformance requirement
On the receipt of an IMMEDIATE ASSIGNMENT message the MS shall send PAGING RESPONSE containing the correct TMSI stored in the SIM.
3GPP TS 11.11, subclauses 11.2.1 and 11.4.5, 3GPP TS 04.08 / 3GPP TS 24.008, subclause 10.5.1.4.
27.3.3 Test purpose
1) To verify that the ME uses the TMSI stored in the SIM.
2) To verify that the ME can handle a TMSI of maximum length.
3) To verify that the ME does not respond to page requests containing a previous TMSI.
27.3.4 Method of test
27.3.4.1 Initial conditions
Prior to this test, the ME shall have been operated with a SIM containing TMSI "2143". This will be achieved by executing the previous test (27.2) prior to this test. Only under this condition will test be verified.
The SS transmits on the BCCH, with the following network parameters:
Attach/detach: disabled.
LAI-MCC: 246
LAI-MNC 81 or 813 (see Note 0)
LAI-LAC: 0001
Access control: unrestricted.
The default SIM is used with the following exception:
EFLOCI (Location Information)
Logically: LAI-MCC: 246
LAI-MNC: 81 or 813 (See Note 0)
LAI-LAC: 0001
TMSI: "21430000"

The SIM is installed into the ME and the MS is powered on.
27.3.4.2 Procedure
a) The SS sends PAGING REQUEST to the MS using the TMSI "2143".
b) The SS sends PAGING REQUEST to the MS using the TMSI stored in the SIM.
c) After receipt of a CHANNEL REQUEST from the MS, the SS sends IMMEDIATE ASSIGNMENT to the MS.
d) After receipt of a PAGING RESPONSE from the MS, the SS sends CHANNEL RELEASE to the MS.
27.3.5 Test requirement
1) After step a) the MS shall not respond to the PAGING REQUEST.
2) After step c) the MS shall send PAGING RESPONSE to the SS containing the TMSI stored in the SIM.
