When receiving the DETACH REQUEST message and the detach type IE indicates "re-attach required", the MS shall deactivate the PDP contexts and deactivate the logical link(s), if any. The MS shall then send a DETACH ACCEPT message to the network and shall change state to GMM-DEREGISTERED. The MS shall, after the completion of the GPRS detach procedure, initiate a GPRS attach procedure. The MS should also activate PDP context(s) to replace any previously active PDP contexts.

NOTE: In some cases, user interaction may be required and then the MS cannot activate the PDP context(s) automatically.

A GPRS MS operating in MS operation mode A or B in network operation mode I, which receives an DETACH REQUEST message with detach type indicating "re-attach required" or "re-attach not required" and no cause code, is only detached for GPRS services in the network.

For Class B MS, CS services are not possible unless an IMSI attach procedure is performed.

Different types of MS 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.

Verify that the MS initiates a TBF connection and sends an UPLINK RLC DATA BLOCK as a response to the paging request.

MS

The MS is switched off or power is removed (see PICS).

MS -> SS

DETACH REQUEST

Message not sent if power is removed.

44.2.2.2.6 GPRS detach / rejected / GPRS services not allowed in this PLMN

44.2.2.2.6.1 Conformance requirement

If the network performs a GPRS detach procedure with the cause ‘GPRS services not allowed in this PLMN’ the Mobile Station shall:

1. The MS shall delete any RAI, P-TMSI, P-TMSI signature, and GPRS ciphering key sequence number stored, shall set the GPRS update status to GU3 ROAMING NOT ALLOWED (and shall store it according to section 4.1.3.2) and shall change to state GMM-DEREGISTERED.

2. The MS shall store the PLMN identity in the "forbidden PLMNs for GPRS service" list.

3. A GPRS MS operating in MS operation mode A or B in network operation mode I shall set the timer T3212 to its initial value and restart it, if it is not already running.

4. A GPRS MS operating in MS operation mode A or B, is still IMSI attached for CS services in the network.

Reference(s):

3GPP TS 04.08 / 3GPP TS 24.008 subclause 4.7.4.2.2

44.2.2.2.6.2 Test purpose

To test the behaviour of the MS if the network orders the GPRS detach procedure with the cause ‘ GPRS services not allowed in this PLMN.

44.2.2.2.6.3 Method of test

Initial conditions

System Simulator:

Two cells (not simultaneously activated), cell A in MCC1/MNC2/LAC1/RAC1, cell B in MCC2/MNC1/LAC1/RAC1.

All two cells are operating in network operation mode II. The PLMN of the two cells should NOT be that of the Mobile Station Home PLMN.

Mobile Station:

The MS has a valid TMSI-1, P-TMSI-1 and RAI-8. MS is Idle Updated on Cell A.

Specific PICS statements:

– MS operation mode B (TSPC_operation_mode_B)

– MS operation mode C (TSPC_operation_mode_C) (only if mode B not supported).

– 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 orders a GPRS detach with the cause value ‘ GPRS services not allowed in this PLMN‘. The SS checks that the MS responds to RR paging (in case of MS operation mode B) and does not respond to packet paging, does not perform periodic ROUTING AREA UPDATE procedure in this PLMN and performs periodic ROUTING AREA UPDATE procedure when new PLMN is entered.

T3312: set to 6 minutes.

Maximum duration of test

20 minutes.

Message

Comments

SS

The following messages are sent and shall be received on cell A.

1

MS

The MS is set in MS operation mode B or C (see PICS).

2

SS

The SS activates cell A.

3

MS

The MS is powered up or switched on and initiates an attach (see PICS).

4

MS -> SS

ATTACH REQUEST

Attach type = ‘GPRS attach’

Mobile identity = P-TMSI-1

Routing area identity = RAI-8

5

SS -> MS

ATTACH ACCEPT

Attach result = ‘GPRS only attached’

Mobile identity = P-TMSI-2

P-TMSI-2 signature

Routing area identity = RAI-8

ATTACH COMPLETE

7

SS -> MS

DETACH REQUEST

Cause = ‘GPRS services not allowed in this PLMN’

8

MS -> SS

DETACH ACCEPT

Steps 9, 10 and 11 are only performed for MS Operation Mode B.

9

SS -> MS

SS pages the MS with mobile identity of TMSI-1 and paging order for RR connection according to the channel combination of the cell.

10

MS -> SS

Verify that the MS initiates a RR connection and sends a PAGING RESPONSE with mobile identity TMSI-1.

11

SS

SS releases the RR connection.

12

SS pages the MS with Mobile identity = P-TMSI-2 and paging order for TBF establishment according to the channel combination of the cell.

13

No response from the MS to the request. This is checked for 10 seconds.

14

No ROUTING AREA UPDATE REQUEST sent to the SS
(SS waits Ready Timer Period (T3314) + Periodic Routing Area Updating timer (T3312) (+10%)).

The following messages are sent and shall be received on cell B.

15

SS

The SS deactivates cell A and activates cell B.

16

MS

Cell B is preferred by the MS.

Step 17 is only performed for MS Operation Mode B.
