12.2.2.1 Combined PS attach / PS and non-PS attach accepted

12.2.2.1.1 Definition

12.2.2.1.2 Conformance requirement

1) If the network accepts the combined PS attach procedure (signalled by an IMSI) and allocates a P-TMSI, the UE shall acknowledge the P-TMSI and continue communication with the P-TMSI.

2) If the network accepts the combined PS attach procedure (signalled by P-TMSI) and reallocates a new P-TMSI, the UE shall acknowledge the new P-TMSI and continue communication with the new P-TMSI.

3) If the network accepts the combined PS attach procedure (signalled by a P-TMSI) from the UE without reallocation of the previously used P-TMSI, the UE shall continue communication with the previously used P-TMSI.

4) If the network accepts the combined PS attach procedure and determines that IMSI shall be used in CS operations, the UE shall continue communication with the IMSI for CS operations.

5) If the network accepts the combined PS attach procedure and determines that a TMSI shall be used in CS operations, the UE shall continue communication with the TMSI for CS operations.

Reference

3GPP TS 24.008 clause 4.7.3.2.

12.2.2.1.3 Test purpose

To test the behaviour of the UE if the network accepts the PS attach procedure.

The following cases are identified:

1) P-TMSI / P-TMSI signature is allocated;

2) P-TMSI / P-TMSI signature is reallocated;

3) Old P-TMSI / P-TMSI signature is not changed;

4) Mobile terminating CS call is allowed with IMSI;

5) Mobile terminating CS call is allowed with TMSI.

12.2.2.1.4 Method of test

Initial condition

System Simulator:

One cell operating in network operation mode I. ATT flag is set to 0.

User Equipment:

The UE has a valid IMSI.

Related ICS/IXIT statements

Support of PS service Yes/No
UE operation mode A Yes/No
Switch off on button Yes/No
Automatic PS attach procedure at switch on or power on Yes/No
UE supports CS call establishment Yes/No

Test procedure

1) The UE sends an ATTACH REQUEST message with identity IMSI. The SS allocates a P-TMSI and returns ATTACH ACCEPT message with a P-TMSI. The UE acknowledge the P-TMSI by sending ATTACH COMPLETE message. Further communication UE – SS is performed by the new P-TMSI. For CS calls, the IMSI is used.

2) The UE is CS paged in order to verify that the IMSI is used for CS calls.

3) The UE is PS paged in order to verify that the new P-TMSI is used for PS services.

4) The UE sends an ATTACH REQUEST message with identity P-TMSI. The SS allocates a new P-TMSI and returns ATTACH ACCEPT message with the new P-TMSI and a new TMSI. The UE acknowledge the P-TMSI and the TMSI by sending ATTACH COMPLETE message. Further communication UE – SS is performed by the new P-TMSI. For CS calls, the new TMSI is used. The UE is CS paged in order to verify that the new TMSI is used for CS services.

5) The UE is PS paged in order to verify that the new P-TMSI is used for PS services. The UE will not answer signalling addressed to the old P-TMSI.

6) The UE sends an ATTACH REQUEST message with identity P-TMSI. The SS accepts the P-TMSI and returns ATTACH ACCEPT message without any P-TMSI. Further communication UE – SS is performed by the previously used P-TMSI.

7) The UE is PS paged in order to verify that the previously used P-TMSI is used for PS services.

12.2.2.3a Combined PS attach / NMO-I enabled in UE

12.2.2.3a.1 Definition

12.2.2.3a.2 Conformance requirement

1) The network operation mode (mode I, II, or III) shall be indicated as system information to MSs. Additional system information can indicate that MSs configured to use the extended NMO I system information (see TS 24.368 [111]) shall use NMO I, regardless of what NMO is indicated by system information for other MSs. If this additional system information is absent, MSs configured to use the extended NMO I system information shall use the system information that represents the network operation mode for other MSs. From these indications, the MS determines which mode applies to it. That mode shall be used when using the procedures described in other clauses of this specification.

2) If the parameter "NMO_I_Behaviour" in the NAS configuration Management Object or USIM is set to the value of "1", the bit 2 "NMO I" of system information is applied.

3) If the network accepts the combined PS attach procedure (signalled by an IMSI) and allocates a P-TMSI, the UE shall acknowledge the P-TMSI and continue communication with the P-TMSI.

Test procedure

1) The UE reads the SIB1 IE "CN domain specific GSM-MAP NAS system information" and uses the value of the “NMO I, Network Mode of Operation I” bit.

2) The UE sends an ATTACH REQUEST message with identity IMSI. The SS allocates a P-TMSI and returns ATTACH ACCEPT message with a P-TMSI. The UE acknowledge the P-TMSI by sending ATTACH COMPLETE message. Further communication UE – SS is performed by the new P-TMSI. For CS calls, the IMSI is used.

2) The UE is CS paged in order to verify that the IMSI is used for CS calls.

3) The UE is PS paged in order to verify that the new P-TMSI is used for PS services.

To test that the UE deletes the list of forbidden LAs when power is switched off.

12.2.2.7a.4 Method of test

Initial condition

System Simulator:

Three cells (not simultaneously activated), cell A in MCC1/MNC1/LAC1/RAC1 (RAI-1), cell B in MCC1/MNC1/LAC1/RAC2 (RAI-4), cell C in MCC2/MNC1/LAC2/RAC1 (RAI-6).
All cells are operating in network operation mode I.

The PLMN contains Cell C is equivalent to the PLMN that contains Cell A.

NB: i) Cell C will be mapped to Cell 4 as found in TS 34.108 clause 6.1.4.1.

User Equipment:

The UE has a valid TMSI, P-TMSI and RAI.

Related ICS/IXIT statements

Support of PS service Yes/No
UE operation mode A Yes/No
Switch off on button Yes/No
Automatic PS attach procedure at switch on or power on Yes/No
PS attach attempted automatically by outstanding request Yes/No

Test procedure

The SS rejects a combined PS attach with the cause value ‘Location Area not allowed’. The SS checks that the UE does not perform combined PS attach while in the location area, performs PS attach when a new location area is entered and deletes the list of forbidden LAs when switched off. CS services are not possible unless an IMSI attach procedure is performed.

Different types of UE may use different methods to periodically clear the list of forbidden location areas (e.g. every day at 12am). If the list is cleared while the test is being run, it may be necessary to re-run the test.

12.2.2.10.3 Test purpose

Test purpose

To test the behaviour of the UE in case of paging permission with access control.

The following cases are identified:

1) To verify that, when a combined attach procedure is triggered and SIB3 indicates that the “Location/Registration Restriction Indicator” is set to “All” and all access classes in “Location/Registration Access Class Barred List” are set to barred, the UE does not attempt to make any attach procedure.

2) To verify that, when a combined attach procedure is triggered and SIB3 indicates that “Location/Registration Restriction Indicator” is set to “All” and restriction status is set to "no restriction”, the UE performs a combined attach procedure.

12.2.2.10.4 Method of test

Initial condition

System Simulator:

One cell operating in network operation mode I.
“Location/Registration Restriction Indicator ” IE in SIB3 is set to “All”.
All access classes in “Location/Registration Access Class Barred List ” IE in SIB3 are set to barred.

Test procedure

The UE is switched on. The UE shall not perform any attach procedure as SS indicates in SIB3 that “Location/Registration Restriction Indicator” is set to “All” and all access classes in the “Location/Registration Access Class Barred List ” are set to barred.

The SS changes the restriction status in SIB3 to indicate no restriction. The UE is triggered to perform a combined attach procedure. The SS checks that UE performs a combined attach procedure.
