12.4.2 Combined routing area updating

34.123-13GPPPart 1: Protocol conformance specificationRelease 15TSUser Equipment (UE) conformance specification

The combined routing area updating procedure is a GMM procedure used by PS UEs of UE operation mode A that are IMSI attached for PS and non-PS services. In order to use the combined routing area updating procedure, the network must operate in network operation mode I.

12.4.2.1 Combined routing area updating / combined RA/LA accepted

12.4.2.1.1 Definition

12.4.2.1.2 Conformance requirement

1) If the network accepts the combined routing area updating procedure and reallocates a P-TMSI, the UE shall acknowledge the new P-TMSI and continue communication with the new P-TMSI.

2) If the network accepts the combined routing area updating procedure from the UE without reallocation of the old P-TMSI, the UE shall continue communication with the old P-TMSI.

Reference

3GPP TS 24.008 clause 4.7.5.2.

12.4.2.1.3 Test purpose

To test the behaviour of the UE if the network accepts the combined routing area updating procedure.

The following cases are identified:

1) P-TMSI / P-TMSI signature is reallocated.

2) Old P-TMSI / P-TMSI signature is not changed.

3) Mobile terminating CS call is allowed with IMSI.

4) Mobile terminating CS call is allowed with TMSI.

12.4.2.1.4 Method of test

Initial condition

System Simulator:

Two cells, cell A in MCC1/MNC1/LAC1/RAC1 (RAI-1), cell B in MCC1/MNC1/LAC1/RAC2 (RAI-4).
Both cells operating in network operation mode I.

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) A combined PS attach procedure is performed. The UE sends a ROUTING AREA UPDATE REQUEST message. The SS reallocates the P-TMSI, unassigns the TMSI and returns ROUTING AREA UPDATE ACCEPT message with a new P-TMSI and IMSI. The UE acknowledge the new P-TMSI by sending ROUTING AREA UPDATE 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) A combined PS attach procedure is performed. The UE sends an ROUTING AREA UPDATE REQUEST message. The SS accepts the P-TMSI signature and returns ROUTING AREA UPDATE ACCEPT message without any P-TMSI and with a new TMSI. The UE acknowledge the new TMSI by sending ROUTING AREA UPDATE COMPLETE message. Further communication UE-SS is performed by the old P-TMSI. For CS calls, the new TMSI is used.

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

Test procedure

After attach, the UE sends an ROUTING AREA UPDATE REQUEST message. The SS allocates a new P-TMSI signature and returns ROUTING AREA UPDATE ACCEPT message. GMM cause ‘MSC temporarily not reachable’ or ‘Network failure’ is indicated from SS. The cause code is arbitrarily chosen. This procedure is repeated until the routing area updating attempt counter is equal to five. An UE operation mode A UE may perform an MM IMSI attach procedure (according to the ICS statement). Further communication UE – SS is performed by the P-TMSI. The existence of a signalling channel is verified by a request for mobile identity. It is further verified that the UE after a successful IMSI attach procedure can perform CS services.

Proc 2: Test procedure 2

Initial condition

System Simulator:

Two cells, cell A in MCC2/MNC1/LAC1/RAC1 (RAI-2, Not HPLMN), cell B in MCC2/MNC1/LAC2/RAC1 (RAI-6, Not HPLMN).
Both cells are operating in network operation mode I.

User Equipment:

The UE has a valid IMSI. UE is Idle Updated on cell A.

Related ICS/IXIT statements

Support of PS service Yes/No
UE operation mode A Yes/No
USIM removal possible without powering down 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

The SS rejects a combined routing area updating with the cause value ‘Roaming not allowed in this location area’. The UE is switched off for 10 seconds and switched on again. The SS checks that a combined PS attach is possible on the cell on which the previous combined routing area updating had been rejected.

If USIM removal is possible without switching off:
The SS rejects a routing area updating with the cause value ‘Roaming not allowed in this location area’. The USIM is removed and inserted in the UE. The SS checks that a PS attach procedure and routing area updating procedure is possible on the cell on which the routing area updating had previously been rejected.

12.4.2.11 Combined routing area updating / abnormal cases / access barred due to domain specific access restriction for CS domain

12.4.2.11.1 Definition

This test case is applicable for Rel-5 UEs supporting DSAC and Rel-6 or later UEs.

12.4.2.11.2 Conformance requirement

If the PS or CS domain is barred because of domain specific access control, a GPRS MS operating in mode A or B in a network that operates in mode I shall act as if in network operation mode II or III (depending on whether a PCCCH is present in Gb-mode) and access to the barred domain shall be stopped entirely. If the MS detects that a domain is barred, this shall not trigger any MM or GMM specific procedure.

Additionally the MS shall treat the expiry of T3312 when the PS domain changes from barred to unbarred, analogous to the descriptions for the cases when the timer expires out of coverage or in a cell that does not support GPRS (see subclause 4.7.2.2).

If timer T3312 expires and both the PS and CS domain are barred, then a GPRS MS operating in mode A or B in a network that operates in mode I shall treat the expiry of T3312 when the GPRS MS detects that the PS or CS domain becomes unbarred, analogous to the descriptions for the cases when the timer expires out of coverage (see subclause 4.7.2.2).

If the PS domain is barred and timer T3312 expires during an ongoing CS connection, then a GPRS MS operating in mode A or B in a network that operates in mode I shall treat the expiry of T3312 when the MM state MM-IDLE is entered, analogous to the descriptions for the cases when the timer expires out of coverage or in a cell that does not support GPRS (see subclause 4.7.2.2), or in a cell where the PS domain is barred.

A GPRS MS operating in mode A or B in a network that operates in mode I shall perform a combined routing area update procedure indicating "combined RA/LA updating with IMSI attach" (in order to establish the Gs association in the MSC/VLR) when the following conditions are fulfilled:

– the GPRS MS detects that CS or PS domain or both change from barred to unbarred;

– as a result of the change of the domain specific barring status, both domains are unbarred; and

– for the last attempt to update the registration of the location area an MM specific procedure was performed (see subclause 4.7.5.2.1) or for the last attempt to update the registration of the routing area a normal routing area update was performed.

Reference
