8.3.11.1 Inter-RAT cell change order from UTRAN/To GPRS/CELL_DCH/Success with UEA1/UIA1, GEA2 ciphering

8.3.11.1.1 Definition

This test case verifies the UE behaviour in the scenario of interRAT cell change order from UTRAN to GERANincluding the UE capability to switch between different ciphering algorithms applied in each RAT: the UIA1/UEA1 are applied in the UTRAN cell, and, the GEA/2 is applied in the GERAN cell.

8.3.11.1.2 Conformance requirement

The purpose of the inter-RAT cell change order procedure is to transfer, under the control of the network, a connection between the UE and UTRAN to another radio access technology (e.g. GSM). This procedure may be used in CELL_DCH and CELL_FACH state. This procedure may be used when no RABs are established or when the established RABs are only from PS domain. This procedure may not be used when there is no PS signalling connection.

The procedure is initiated when UTRAN orders a UE in CELL_DCH or CELL_FACH state, to make a cell change to a radio access technology other than UTRAN, e.g. GSM.

To initiate the procedure, UTRAN sends a CELL CHANGE ORDER FROM UTRAN message.

The UE shall be able to receive a CELL CHANGE ORDER FROM UTRAN message and perform a cell change order to another RAT, even if no prior UE measurements have been performed on the target cell.

If the variable ESTABLISHED_SIGNALLING_CONNECTIONS does not include the CN domain identity "PS domain", or if the variable ESTABLISHED_SIGNALLING_CONNECTIONS includes the CN domain identity "CS domain":

1> the UE behaviour is not specified.

The UE shall:

1> start timer T309; and

1> establish the connection to the other radio access technology, as specified within IE "Target cell description". This IE specifies the target cell identity, in accordance with the specifications for that other RAT. In case the target cell is a GSM/ GPRS cell, IE "Target cell description" may also include IE "NC mode", which specifies the cell selection mode to be applied in the target cell; and

1> if IE "NC mode" is not included in the CELL CHANGE ORDER FROM UTRAN:

2> retrieve it from the target cell as specified in [43];

2> act upon IE "NC mode" as specified in [43].

1> if the IE "RAB Information List" is included in the CELL CHANGE ORDER FROM UTRAN message:

2> ignore the contents of the IE "RAB Information List".

NOTE: Requirements concerning the establishment of the radio connection towards the other radio access technology and the signalling procedure are outside the scope of this specification. In case of GSM/GPRS proceed according to the procedure Network control cell reselection procedure as specified in [44].

The UE regards the procedure as completed when it has received a successful response from the target RAT, e.g. in case of GSM when it received the response to a (PACKET) CHANNEL REQUEST in the new cell.

Upon successful completion of the cell change order, the UE shall:

1> stop timer T309;

1> clear or set variables upon leaving UTRA RRC connected mode as specified in subclause 13.4.

Upon indication of the UE having successfully completed the cell change order, UTRAN should:

1> release the radio connection; and

1> remove all context information for the concerned UE.

NOTE: The release of the UMTS radio resources is initiated from another RAT.

8.3.11.1.3 Test purpose

To test that the UE shall be able to receive a CELL CHANGE ORDER FROM UTRAN message in CELL_DCH state and perform a cell change to another RAT, even if no prior UE measurements have been performed on the target cell. The UE regards the procedure as completed when it has received a successful response from the target RAT, e.g. in case of GSM when it received the response to a (PACKET) CHANNEL REQUEST in the new cell.

The UIA1/UEA1 are applied in the UTRAN cell. The GEA/2 ciphering algorithm is applied in the GERAN cell. The UE shall be able to handle the change of algorithm when moving from UTRAN to GERAN.

– UE supports GSM-P, GSM-E, GSM-DCS, GSM-450, GSM-480, GSM-850, GSM-PCS, GSM-710, GSM 750, T_GSM-810

Test Procedure

The SS starts the UTRAN cell and brings the UE into PS-DCCH+DTCH_DCH (State 6-10); the UIA1/UEA1 are applied. The SS starts GPRS cell, then sends CELL CHANGE ORDER FROM UTRAN indicating the target cell description, GPRS cell, to the UE through DCCH of the serving UTRAN cell. After the UE receives the command it shall configure itself accordingly and switch to the new channel on the target GPRS cell. The SS checks whether the cell change is performed by checking that the UE receives a successful response to the CHANNEL REQUEST message from the SS through GPRS cell. The UE sends a RA UPDATE REQUEST message to indicate that the UTRAN UE context needs to be transferred to GPRS. During the procedure for camping on the GERAN cell the SS requests and applies the GEA/2 ciphering algorithm – the UE is expected to be able to handle the change of algorithms between the two RATs.

Test Procedure

The SS starts the UTRAN cell and brings the UE into PS_DCCH+DTCH_FACH (state 6-11). The SS starts GPRS cell, then sends CELL CHANGE ORDER FROM UTRAN indicating the target cell description, GPRS cell, to the UE through DCCH of the serving UTRAN cell. The UE starts the timer T309. After the UE receives the command it shall configure itself accordingly but cannot complete the cell change, as SS does not respond to the Channel Request message transmitted by UE till the timer T309 expires. The SS checks that the cell change has failed by checking that the UE transmits the CELL CHANGE ORDER FROM UTRAN FAILURE message to the SS in UTRAN cell.

Table 8.3.11.6 illustrates the downlink power to be applied for the 2 UTRAN cells at various time instants of the test execution. SS switches the power settings between columns "T0" and "T1", whenever the description in multi-cell condition specifies a reverse in the transmission power settings for cell 1 and cell 2.

The SS starts the UTRAN cell and brings the UE into PS-DCCH+DTCH_FACH (state 6-11). The SS starts GPRS cell, then sends CELL CHANGE ORDER FROM UTRAN indicating the target cell description, GPRS cell, to the UE through DCCH of the serving UTRAN cell. The UE receives the command and configures itself accordingly but cannot complete the cell change and wants to revert to the old configuration, but the UE cannot revert to the old configuration because the SS shall not use the old configuration. The SS configures its downlink transmission power settings according to columns "T1" in table 8.3.11.6. The UE transmits CELL UPDATE message on uplink CCCH with IE "Cell update cause" set to "cell reselection". The SS shall transmit CELL UPDATE CONFIRM message on downlink CCCH after receiving CELL UPDATE message. The UE transmits the CELL CHANGE ORDER FAILURE message to the SS in UTRAN cell, on the DCCH using AM RLC, setting the value of IE " Inter-RAT change failure " to " physical channel failure".

Test Procedure

The SS starts the UTRAN cell and brings the UE into PS-DCCH+DTCH_DCH (state 6-10). The SS then sends a CELL CHANGE ORDER FROM UTRAN message not including a valid cell change order from UTRAN message in accordance with the protocol specifications for the target RAT, to the UE through DCCH of the serving UTRAN cell. The UE receives the command and finds that the cell change order message is Invalid. The SS checks that the cell change is failed by checking that the UE transmits the CELL CHANGE ORDER FROM UTRAN FAILURE message to the SS in UTRAN cell with the IE “Inter-RAT change failure cause” set to “protocol error”.

Test Procedure

The SS starts the UTRAN cell and brings the UE into PS-DCCH+DTCH_DCH (State 6-10). The SS starts GPRS cell, then sends CELL CHANGE ORDER FROM UTRAN indicating the target cell description, GPRS cell, and including a set of GERAN system information which describes a GPRS cell different to the target cell, and replaced SI 3 with all ‘1’s, to the UE through DCCH of the serving UTRAN cell. This is to test that if any of the SI signalled is not correct, all of the IE is ignored. After the UE receives the command it shall configure itself accordingly and switch to the new channel on the target GPRS cell, ignoring the IE "GERAN System Information" and reading this instead from cell 2. The SS checks whether the cell change is performed by checking that the UE receives a successful response to the CHANNEL REQUEST message from the SS through GPRS cell. The UE sends a RA UPDATE REQUEST message to indicate that the UTRAN UE context needs to be transferred to GPRS.

Test Procedure

The UE is in CELL_DCH state and only signalling radio bearers have been established.

The SS transmits a RADIO BEARER SETUP message including the RAB Information for setup IE to configure PS domain RAB and perform SRB mapping from DCH to EDCH/HSDPA (with MIMO configured for L1 with PCI restriction and S-CPICH power offset). The UE transmits a RADIO BEARER SETUP COMPLETE on DCCH. The UE shall configure the lower layers with signalled S-CPICH Power offset. UE sends combined CQI/PCI reports of type A/B continuously every 2 ms. The PCI values reported shall be restricted to 0 or 3 for type A CQIs where one transport block is preferred. For type A CQIs where two transport blocks are preferred, restriction shall not apply.

The SS configures the GPRS cell, and then sends a CELL CHANGE ORDER FROM UTRAN message indicating the target cell description, GPRS cell, to the UE through DCCH of the serving UTRAN cell. After the UE receives the command it shall configure itself accordingly and switch to the new channel on the target GPRS cell. The SS checks whether the cell change is performed by checking that the UE receives a successful response to the CHANNEL REQUEST message from the SS through GPRS cell. The UE sends a ROUTING AREA UPDATE REQUEST message to indicate that the UTRAN UE context needs to be transferred to GPRS.

Test Procedure

The UE is in CELL_DCH state and only signalling radio bearers have been established.

The SS transmits a RADIO BEARER SETUP message including the RAB Information for setup IE to configure PS domain RAB and perform SRB mapping from DCH to E-DCH/HSDPA (with MIMO configured for L1 ). The tx-diversity mode for F-DPCH shall be set to STTD.The UE transmits a RADIO BEARER SETUP COMPLETE on DCCH. UE sends combined CQI/PCI reports of type A/B continuously every 2 ms.

The SS configures GPRS cell, then sends CELL CHANGE ORDER FROM UTRAN indicating the target cell description, GPRS cell, to the UE through DCCH of the serving UTRAN cell. The UE starts the timer T309. After the UE receives the command it shall configure itself accordingly but cannot complete the cell change, as SS does not respond to the CHANNEL REQUEST message transmitted by UE till the expiry of T309 timer. The SS checks that the cell change has failed by checking that the UE transmits the CELL CHANGE ORDER FROM UTRAN FAILURE message to the SS in UTRAN cell.The SS checks that UE configures MIMO for L1 and tx-diversity mode for F-DPCH to be STTD. UE sends combined CQI/PCI reports of type A/B continuously every 2 ms.

8.3.11.18.5 Test requirements

In step 2 the UE shall transmit a RADIO BEARER SETUP COMPLETE message

In step 3 the UE shall transmit composite CQI/PCI reports of type A or type B. The SS shall check that for 500 consecutive CQI reports, 250 are type A and 250 of type B. PCI values of 0 or 3 shall be used by the UE for type A CQIs where one transport block is preferred. For type A CQIs where two transport blocks are preferred, the restriction does not apply. The UE shall configure the lower layers with signalled S-CPICH Power offset.

In step 7 the UE shall transmit a CHANNEL REQUEST message on RACH.

In step 9 the SS shall receive CELL CHANGE ORDER FROM UTRAN FAILURE message on the old channel of the UTRAN cell.

In step 10 the UE shall transmit composite CQI/PCI reports of type A or type B. The SS shall check that for 500 consecutive CQI reports, 250 are type A and 250 of type B. PCI values of 0 or 3 shall be used by the UE for type A CQIs where one transport block is preferred. For type A CQIs where two transport blocks are preferred, the restriction does not apply. The UE shall configure the lower layers with signalled S-CPICH Power offset.
