44.2.3 Routing area updating procedure

3GPP51.010-1Mobile Station (MS) conformance specificationPart 1: Conformance specificationTS

This procedure is used to update the actual routing area of an MS in the network.

44.2.3.1 Normal routing area updating

The routing area updating procedure is a GMM procedure used by GPRS MSs of MS operation mode B or C that are IMSI attached for GPRS services only.

44.2.3.1.1 Routing area updating / accepted

44.2.3.1.1.1 Conformance requirement

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

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

Reference(s):

3GPP TS 04.08 / 3GPP TS 24.008 subclause 4.7.5.1.

44.2.3.1.1.2 Test purpose

To test the behaviour of the MS if the network accepts the 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.

44.2.3.1.1.3 Method of test

44.2.3.1.1b Routing area updating / accepted / PSM

44.2.3.1.1b.1 Conformance requirement

An MS supporting PSM may request the network to assign a value for T3324 by including a requested timer value in:

– the ATTACH REQUEST or ROUTING AREA UPDATE REQUEST message (in A/Gb mode and Iu mode ); or

– the ATTACH REQUEST or TRACKING AREA UPDATE REQUEST message (in S1 mode).

The value of timer T3324 can be sent by the network to the MS in:

– the ATTACH ACCEPT or ROUTING AREA UPDATE ACCEPT message (in A/Gb mode and Iu mode ); and

– the ATTACH ACCEPT or TRACKING AREA UPDATE ACCEPT message (in S1 mode).

The network accepts the use of PSM by providing a specific value for timer T3324 when accepting the attach or routing area updating procedure. The MS may use PSM only if the network has provided the T3324 value IE during the last attach or routing area updating procedure with a value different from "deactivated".

Periodic routing area updating is used to periodically notify the availability of the MS to the network. The value of the update type IE in the ROUTING AREA UPDATE REQUEST message shall indicate "periodic updating". The procedure is controlled in the MS by timer T3312. When timer T3312 expires, the periodic routing area updating procedure is started. Start and reset of timer T3312 is described in subclause 4.7.2.2.

The normal routing area updating procedure is initiated:

– when the MS detects a change of the routing area in state GMM-REGISTERED;

– when the MS determines that GPRS resumption shall be performed;

– when the MS needs to update the network with the new MS Radio Access Capability IE;

– when the MS needs to update the network with the new DRX parameter IE;

– in Iu mode, to re-synchronize the PMM mode of MS and network after RRC connection release with cause "Directed signalling connection re-establishment", see subclause 4.7.2.5;

– in Iu mode, to re-synchronize the PMM mode of MS and network after inter-system change not due to PS handover from PMM-CONNECTED mode in Iu mode to A/Gb mode or S1 mode, if the MS performs an inter – system change back to Iu mode without sending a ROUTING AREA UPDATE REQUEST message while in A/Gb mode or a TRACKING AREA UPDATE REQUEST message while in S1 mode;

– in Iu mode and A/Gb mode, after intersystem change from S1 mode, and the GMM receives an indication of "RRC connection failure" from lower layers due to lower layer failure while in S1 mode. In this case, if the TIN indicates "RAT-related TMSI", the MS shall set the TIN to "GUTI" before initiating the routing area updating procedure;

– in A/Gb mode, after intersystem change from S1 mode if the TIN indicates "RAT-related TMSI", but the MS is required to perform routing area updating for IMS voice termination as specified in annex P.4;

– when the MS enters GMM-REGISTERED.NORMAL-SERVICE and the TIN indicates "GUTI";

– when the MS has selected a CSG cell whose CSG identity and associated PLMN identity are not included in the Allowed CSG list; or in the Operator CSG list;

– when the MS supports SRVCC and changes the mobile station classmark 2, mobile station classmark 3 or the supported codecs;

– when the MS changes the MS network capability information;

– when the UE’s usage setting or the voice domain preference for E-UTRAN change in the MS;

– when the MS activates mobility management for IMS voice termination as specified in annex P.2 and the TIN indicates "RAT-related TMSI";

– upon reception of a paging indication, using P-TMSI, even if the timer T3346 is running and the MS is in state GMM-REGISTERED.ATTEMPTING-TO-UPDATE;

– in A/Gb mode, after intersystem change from S1 mode via cell change order procedure not due to CS fallback, if the TIN indicates "RAT-related TMSI"; in this case the MS shall set the TIN to "GUTI" before initiating the routing area updating procedure;

– in A/Gb mode, after Inter RAT handover from S1 mode or Iu mode;

– when the UE needs to request the use of PSM or needs to stop the use of PSM; or

– when a change in the PSM usage conditions at the MS requires a different timer T3312 value or different timer T3324 value.

NOTE: A change in the PSM usage conditions at the MS can include e.g. a change in the MS configuration, a change in requirements from upper layers or the battery running low at the MS.

If the MS supports PSM and requests the use of PSM, the MS shall include the T3324 value IE with a requested timer value in the ROUTING AREA UPDATE REQUEST message. When the MS includes the T3324 value IE and the MS indicates support for extended periodic timer value in the MS network feature support IE, it may also include the T3312 extended value IE to request a particular T3312 value to be allocated.

Reference(s):

3GPP TS 24.008 clause 4.7.2.8, 4.7.2.9, 4.7.5.1

44.2.3.1.1b.2 Test purpose

1) To verify that the MS indicates PSM by providing a T3324 value IE during the RAU procedure

2) To verify that the MS accepts the value for timer T3324 provided by the network

3) To verify that the MS, upon expiry of the timer T3324 deactivate the AS layer and activate PSM by entering the state GMM-REGISTERED.NO-CELL-AVAILABLE

4) To verify that the MS can deactivate PSM.

1) If the network rejects a routing area updating procedure from the Mobile Station with the cause ‘location area not allowed’ the Mobile Station shall:

1.1 not perform GPRS attach when in the same location area;

1.2 delete the stored RAI, GPRS-CKSN, P-TMSI and P-TMSI signature;

1.3 store the LA in the ‘forbidden location areas for regional provision of service’.

2) If the network rejects a routing area updating procedure from the Mobile Station with the cause ‘location area not allowed’ the Mobile Station shall:

2.1 perform GPRS attach when a new location area is entered;

2.2 delete the list of forbidden LAs after switch off (power off).

Reference(s):

3GPP TS 04.08 / 3GPP TS 24.008 subclauses 4.7.5.1.

44.2.3.1.4.2 Test purpose

To test the behaviour of the MS if the network rejects the routing area updating procedure of the MS with the cause ‘Location Area not allowed’.

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

44.2.3.1.4.3 Method of test

Initial conditions

System Simulator:

Three cells (not simultaneously activated), cell A in MCC1/MNC1/LAC1/RAC1, cell B in MCC1/MNC1/LAC1/RAC2, cell C in MCC1/MNC1/LAC2/RAC1.

All cells are operating in network operation mode II.

Mobile Station:

The MS has a valid IMSI. MS is Idle Updated on cell C.

Specific PICS statements:

– MS operation mode B (TSPC_operation_mode_B).

– MS operation mode C (TSPC_operation_mode_C).

– SIM removal possible without powering down (TSPC_AddInfo_SIMRmv).

– 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 rejects a routing area updating with the cause value ‘Location Area not allowed’. The SS checks that the MS does not perform GPRS attach while in the location area, performs GPRS attach when a new location area is entered and deletes the list of forbidden LAs when switched off.

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

Maximum duration of test

15 minutes.

The MS stays in the current serving cell and applies the normal cell reselection process. The routing area updating procedure is started, if still necessary, when timer T3346 expires or is stopped.

If the update type is "periodic updating", a GPRS MS operating in MS operation mode A or B in network operation mode I is still IMSI attached for CS services in the network.

If S1 mode is supported in the MS, the MS shall handle the EMM parameters EMM state, EPS update status, and tracking area updating attempt counter as specified in 3GPP TS 24.301 [120] for the case when the tracking area update procedure is rejected with the EMM cause with the same value.

An MS configured for NAS signalling low priority indicates this by including the Device properties IE in the appropriate NAS message and setting the low priority indicator to "MS is configured to NAS signalling low priority

"Extended wait time" for PS domain from the lower layers

If the ROUTING AREA UPDATE REQUEST message contained the low priority indicator set to "MS is configured for NAS signalling low priority", the MS shall start timer T3346 with the "Extended wait time" value.

Timer T3346 is running

The MS shall not start the routing area updating procedure unless:

– the READY timer is running (A/Gb mode);

– the MS is accessing the network with access class 11 – 15; or

– the MS is in PMM-CONNECTED mode (Iu mode);

– the MS receives a paging;

– the MS has a PDN connection for emergency bearer services established; or

– the MS is establishing a PDN connection for emergency bearer services; or

– the MS has a PDN connection established without the NAS signalling low priority indication or is establishing a PDN connection without the NAS signalling low priority indication and if the timer T3346 was started due to a NAS request message (ATTACH REQUEST, ROUTING AREA UPDATE REQUEST or SERVICE REQUEST) which contained the low priority indicator set to "MS is configured for NAS signalling low priority". The MS stays in the current serving cell and applies the normal cell reselection process.

The routing area updating procedure is started, if still necessary, when timer T3346 expires or is stopped.

NOTE 2: It is considered an abnormal case if the MS needs to initiate an routing area updating procedure while timer T3346 is running independent on whether timer T3346 was started due to an abnormal case or a non successful case.

1) If the network accepts the combined routing area updating procedure and reallocates a P-TMSI, the MS 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 MS without reallocation of the old P-TMSI, the MS shall continue communication with the old P-TMSI.

Reference(s):

3GPP TS 04.08 / 3GPP TS 24.008 subclause 4.7.5.2.

44.2.3.2.1.2 Test purpose

To test the behaviour of the MS 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.

44.2.3.2.3.3.2 Test Procedure 2

Initial conditions

System Simulator:

Two cells (not simultaneously activated), cell A in MCC1/MNC1/LAC1/RAC1, cell B in MCC1/MNC1/LAC1/RAC2.

Both cells operating in network operation mode I. T3212 is set to 6 minutes.

Mobile Station:

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

Specific PICS statements:

– MS operation mode B (TSPC_operation_mode_B)

– MS operation mode A (TSPC_operation_mode_A).

– Automatic MM IMSI attach procedure at switch-on/power-on (TSPC_AddInfo_auto_MM_IMSI_AP_on_off).

– 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

After attach, the MS 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 MS operation mode B MS may perform an MM IMSI attach procedure (according to the PICS statement). Further communication MS – 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 MS after a successful IMSI attach procedure can perform CS services.

Maximum duration of test

10 minutes.

Expected sequence

Dependent whether the option Automatic MM IMSI attach procedure at switch-on/power-on ‘ is supported or not, the steps 1-28 or 29-62 apply depending on manufacturer (see PICS).

Test procedure

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

For a R97 and R98 MS only, the Mobile identity is IMSI for the combined GPRS attach.

For a R99 or after MS only, the Mobile identity is either IMSI or P-TMSI for the combined GPRS attach.

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

The MS initiates a GPRS attach procedure with identity P-TMSI. In the GPRS attach procedure the MS indicates support of the extended timer value. The SS reallocates the P-TMSI and returns ATTACH ACCEPT message with a new P-TMSI, timer T3312 and the extended value of T3312. The MS acknowledge the new P-TMSI by sending ATTACH COMPLETE message.

When the extended value of timer T3312 times out, the MS sends a ROUTING AREA UPDATE REQUEST message including the T3324 value IE. The SS allocates a P-TMSI and returns a ROUTING AREA UPDATE ACCEPT message providing a value for timer T3324. Upon expiry of the timer T3324, the MS deactivate the AS layer and activate PSM by entering the state GMM-REGISTERED.NO-CELL-AVAILABLE.

Then after the expiry of extended timer T3312, the MS sends a ROUTING AREA UPDATE REQUEST message to the network for wakeup.

Maximum duration of test

24 minutes.
