Test Procedure
The MS, whilst in dedicated mode, is triggered to initiate packet uplink transfer data in RLC acknowledged mode and sends a DTM REQUEST message. On receipt of the DTM REQUEST message, the SS returns a DTM REJECT message, simulating the inability to allocate the requested packet resource. The DTM REJECT message includes a wait indication (T3142) specifying that the MS is to wait 5 seconds before being allowed to re-request resources. The MS is again prompted to initiate an uplink TBF before the wait indication has expired, it is then tested that the MS does not try to access the network until the Wait Indication has expired. After the Wait Indication has expired, the MS initiates the packet access procedure and sends a DTM REQUEST message.
MS supporting DTM shall complete testing for k=1 and MSs indicating support of single slot DTM shall additionally complete testing for k=2.

41.5.1.1.1.4 Uplink TBF establishment with no reallocation of CS resources / Abnormal cases / Inter System to UTRAN Handover Command
41.5.1.1.1.4.1 Conformance requirements
Only valid for a UTRAN capable MS. In dedicated mode or dual transfer mode, a change to UTRAN channel(s) can be requested by the network RR sublayer. This change is performed through the handover to UTRAN procedure.
If the mobile station receives an INTER SYSTEM TO UTRAN HANDOVER COMMAND message during the packet access procedure, the mobile station shall abort the packet access procedure, stop timer T3148 and proceed with the handover to UTRAN procedure as specified in clause 3.4.4a.

Test Procedure
The SS starts the GSM cell and UTRAN cell with cell selection conditions in favour of GSM cell, the MS selects the GSM cell for camping on. The SS brings the MS into the call active state (CC state U10). The MS is then triggered to initiate packet uplink data transfer in RLC acknowledged mode and sends a DTM REQUEST message. On receiving the DTM REQUEST message, requesting uplink resources, the SS configures the dedicated channel corresponding to the pre-configuration in UTRAN cell, then sends INTERSYSTEM TO UTRAN HANDOVER COMMAND message indicating the dedicated channel of the target cell to the MS through the GSM serving cell. After the MS receives the command it shall configure itself accordingly and switch to the dedicated channel of the UTRAN cell. The SS checks whether the handover is performed by confirming the MS transmits a HANDOVER TO UTRAN COMPLETE message to the SS, on the DCCH of the UTRAN cell. To check that CS call is still active, SS Releases the CS call. To check that PDP context is active, SS sends MODIFY PDP CONTEXT REQUEST in UMTS cell. The MS may or may not accept the QoS and replies to the SS accordingly.

Test Procedure
The MS, whilst in dedicated mode, is triggered to initiate packet uplink data transfer in RLC unacknowledged mode and sends a DTM REQUEST message. On receipt of the DTM REQUEST message, requesting uplink resources, the SS reallocates the MS’s CS resources using the ASSIGNMENT COMMAND. Once the MS changes to the newly allocated timeslot the MS re-requests PS resources with a DTM REQUEST message. Once the PS resources are allocated, the MS enters DTM.
The codec to be used in this test is chosen dependent on the capabilities of the MS.
MS supporting DTM shall complete testing for k=1 and MSs indicating support of single slot DTM shall additionally complete testing for k=2.

Test Procedure
The MS, whilst in dedicated mode, is triggered to initiate packet uplink data transfer in RLC acknowledged mode and sends a DTM REQUEST message. On receipt of the DTM REQUEST message, requesting uplink resources, the SS returns a HANDOVER COMMAND to the MS. The HANDOVER COMMAND instructs the switching of the MS to the newly assigned channel and the establishment of lower layer connections. Once the CS connection is established, the MS returns an HANDOVER COMPLETE message on the new main signalling link. The MS may perform Cell Update by sending the GPRS INFORMATION message containing an empty LLC PDU followed by DTM REQUEST to initiate packet uplink data transfer. If the Cell Update is not performed using GPRS INFORMATION, the MS again sends a DTM REQUEST message to initiate packet uplink data transfer, the SS allocates the MS PS resources and the MS enters DTM.
The codec to be used in this test is chosen dependent on the capabilities of the MS.
MS supporting DTM shall complete testing for k=1 and MSs indicating support of single slot DTM shall additionally complete testing for k=2.

Test Procedure
The MS, whilst in dedicated mode, is triggered to initiate packet uplink data transfer and sends a DTM REQUEST message. On receipt of the DTM REQUEST message, requesting uplink resources, the SS reallocates the MS’s CS resources to a different frequency band and assigns the new PS resources. The SS accomplishes the resource assignment by passing a DTM ASSIGNMENT COMMAND message to the MS. Once the MS has received the assignment message, it moves to the new allocation, attempts to reconnect the CS resources, but the SS is not receptive to the establishment of the main signalling bearer in the new cell. The MS reverts back to the old CS resources and sends a DTM ASSIGNMENT FAILURE message on the old main DCCH, with cause value set to "lower layer failure”. The MS re-initiates the packet access procedure and sends a DTM REQUEST message.
MS supporting DTM shall complete testing for k=1 and MSs indicating support of single slot DTM shall additionally complete testing for k=2.

41.5.1.2 Downlink TBF establishment
41.5.1.2.1 Whilst in Ready State
41.5.1.2.1.1 Downlink TBF establishment in Ready State / Successful case
41.5.1.2.1.1.1 Conformance requirements
This procedure is only applicable to a mobile station in dedicated mode and with no TBF allocated. If the mobile station already has an ongoing TBF, the establishment of the downlink packet resource is performed on the PACCH; see 3GPP TS 04.60.
The establishment of a downlink packet resource is initiated by the RR entity on the network side using the packet downlink assignment procedure in dedicated mode. The procedure is triggered by a request from upper layers to transfer an LLC PDU; see 3GPP TS 24.007. The request from upper layers specifies a QoS profile, an RLC mode, DRX parameters and an MS classmark associated with the packet transfer.
The network initiates the packet downlink assignment procedure in dedicated mode by sending a DTM assignment message (i.e. DTM ASSIGNMENT COMMAND or a PACKET ASSIGNMENT) in acknowledged mode on the main DCCH.
The completion of the packet downlink assignment procedure while in dedicated mode depends on the actual assignment message used by the network:
– when the network sends a PACKET ASSIGNMENT message, the packet downlink assignment procedure is completed for the network when assignment message is sent and for the mobile station when it is received.

41.5.2.1 MT CS establishment whilst in packet transfer mode with a downlink TBF established
41.5.2.1.1 Conformance requirements
Paging initiation using PACCH applies when sending a paging request message to a mobile station that is GPRS attached, when the mobile station is in packet transfer mode and the network is able to co-ordinate the paging request with the radio resources allocated for the mobile station on a PDCH. This kind of paging co-ordination shall be provided in network mode of operation I (see 3G TS 23.060). This kind of paging co-ordination may be provided also in network mode of operation II or III. This kind of paging co-ordination shall be provided if the network supports DTM.
When the mobile station responds to a paging request for RR connection establishment, it shall follow the paging response procedures as specified in 3GPP TS 04.18. For that purpose, a mobile station in packet transfer mode or a mobile station that has initiated a packet access procedure may abort any ongoing TBF or the packet access procedure in the following two cases:
– The mobile station requires that the BSS co-ordinates the allocation of radio resources for an RR connection and a simultaneous TBF (GPRS class A mode of operation by means of DTM).

41.5.3.1.1 Uplink TBF establishment with a downlink TBF established and no PS downlink reallocation
41.5.3.1.1.1 Conformance requirements
The mobile station may request establishment of one or more uplink TBFs when there are one or more ongoing downlink TBFs by including a Channel Request Description or the Extended Channel Request Description information element in the (EGPRS) PACKET DOWNLINK ACK/NACK message. Initiation is triggered by a request from upper layers to transfer an upper layer PDU.
When multiple TBF procedures are not supported, the mobile station initiates the packet access procedure by sending the Channel Request Description information element in the (EGPRS) PACKET DOWNLINK ACK/NACK message on the PACCH and starting timer T3168.
On receipt of an (Extended) Channel Request Description information element in the (EGPRS)PACKET DOWNLINK ACK/NACK message, the network may assign radio resources to the mobile station on one or more PDCHs by transmitting an uplink assignment message (e.g. PACKET UPLINK ASSIGNMENT, MULTIPLE TBF UPLINK ASSIGNMENT, PACKET TIMESLOT RECONFIGURE or MULTIPLE TBF TIMESLOT RECONFIGURE message) on the PACCH, or may reject one or more of the requests by sending a PACKET ACCESS REJECT message on the PACCH. If the PACKET TIMESLOT RECONFIGURE message is sent, then the message shall contain the UPLINK_TFI_ASSIGNMENT field.
On receipt of a PACKET UPLINK ASSIGNMENT or PACKET TIMESLOT RECONFIGURE message the mobile station shall stop timer T3168 and switch to the assigned PDCHs.

Test Procedure
Whilst in an active call on timeslot N, the MS receives a PACKET ASSIGNMENT message on the main DCCH, instructing the MS to switch to a designated timeslot and receive data. The SS then starts to transmit to the newly allocated resources. Before the SS completes transmission of the 1000 octets of data, the MS is triggered to initiate an uplink packet transfer. The SS then sends another RLC Downlink Data block to the MS with the S/P bit set to 1. The MS responds by sending a PACKET DOWNLINK ACK/NACK message to the SS including the Channel Request Description IE. The SS allocates uplink resources to the MS with the PACKET UPLINK ASSIGNMENT message. The test procedure is complete when the SS successfully verifies both uplink and downlink transmission are working in parallel.
MS supporting DTM shall complete testing for k=1 and MSs indicating support of single slot DTM shall additionally complete testing for k=2.

41.5.3.1.2 Uplink TBF establishment with a downlink TBF established and PS downlink reallocation
41.5.3.1.2.1 Conformance requirements
The mobile station may request establishment of an uplink transfer during a downlink TBF by including a Channel Request Description information element in the PACKET DOWNLINK ACK/NACK message Initiation is triggered by a request from upper layers to transfer a LLC PDU.
The mobile station initiates the packet access procedure by sending the Channel Request Description information element in the PACKET DOWNLINK ACK/NACK message on the PACCH and starting timer T3168.
On receipt of a Channel Request Description information element in the PACKET DOWNLINK ACK/NACK message, the network may assign radio resources to the mobile station on one or more PDCHs by transmitting a PACKET UPLINK ASSIGNMENT or PACKET TIMESLOT RECONFIGURE message on the PACCH, or may reject the request by sending a PACKET ACCESS REJECT message on the PACCH
On receipt of a PACKET UPLINK ASSIGNMENT or PACKET TIMESLOT RECONFIGURE message the mobile station shall stop timer T3168 and switch to the assigned PDCHs.

Test Procedure
Whilst in an active call on timeslot N, the MS receives a PACKET ASSIGNMENT message on the main DCCH, instructing the MS to switch to a designated timeslot and receive data. The SS then starts to transmit to the newly allocated resources. Before the SS completes transmission of the 1000 octets of data, the MS is triggered to initiate uplink packet transfer. The SS then sends another RLC Downlink Data block to the MS with the S/P bit set to 1. The MS responds by sending a PACKET DOWNLINK ACK/NACK message to the SS including the Channel Request Description IE. The SS allocates uplink resources and reallocates the downlink resources of the MS with the PACKET TIMESLOT RECONFIGURE message. The test procedure is complete when the SS successfully verifies both uplink and downlink transmission are working in parallel.

Test Procedure
The MS, whilst in dedicated mode, is triggered to initiate packet uplink transfer of 1000 octets of data in RLC unacknowledged mode and sends a DTM REQUEST message. On receiving the DTM REQUEST message, requesting uplink resources, the SS assigns the MS an uplink TBF. The SS accomplishes the resource assignment by passing a PACKET ASSIGNMENT message to the MS. On receiving the PACKET ASSIGNMENT message, the MS starts to send RLC DATA BLOCKS to the SS on the assigned PDTCH. Once the MS has sent correctly approximately 500 octets, the SS transmits a PACKET DOWNLINK ASSIGNMENT message allocating the MS downlink packet resources. The test procedure is complete when the SS successfully verifies both uplink and downlink transmission are working in parallel.
MS supporting DTM shall complete testing for k=1 and MSs indicating support of single slot DTM shall additionally complete testing for k=2.
Maximum Duration of Test

41.5.5 Enhanced DTM CS Release
41.5.5.1 SI Acquisition – No Reallocation of PS Resources
41.5.5.1.1 Conformance Requirements
If the mobile station and the network support enhanced DTM CS release procedure, the network may delay the release of the RR connection until the mobile station has received the needed system information, in order to maintain the radio resources on the PDCH(s) after the release of the RR connection.
The network initiates enhanced DTM CS release procedure by sending the PACKET CS RELEASE INDICATION message as specified in 3GPP TS 44.060.
On receipt of PACKET CS RELEASE INDICATION message with the ENHANCED_DTM_CS_RELEASE_INDICATION parameter set to indicate that the RR connection is released, the mobile station shall send the PACKET SI STATUS (respectively PACKET PSI STATUS if the PBCCH is present) message on PACCH to indicate which system information messages were stored while in the dual transfer mode by the mobile station. The following system information (respectively packet system information) messages are required to maintain radio resources and enter packet transfer mode after the release of the RR connection:
– PSI1, PSI2 and PSI14 in the Received PSI Message List; or respectively
– SI13, SI3 and SI1, if present, in the Received SI Message List.
The PSI (respectively SI) messages listed above shall be indicated as the first PSI (respectively SI) messages indicated in the PACKET PSI STATUS (respectively PACKET SI STATUS) messages. If other PSI (respectively SI) messages are indicated in the PACKET PSI STATUS (respectively PACKET SI STATUS) message, the priority order defined in Table 5.5.1.4.3.1 shall apply.
The mobile station is allowed to send the PACKET SI STATUS (respectively PACKET PSI STATUS) message twice and the second sending occurrence of this message shall take place at the first suitable opportunity at least one second after the first transmission of that message. Whenever the mobile station has received all required system information (respectively packet system information) messages, it shall send the PACKET SI STATUS (respectively PACKET PSI STATUS) message at the first suitable opportunity, even if it has already sent the PACKET SI STATUS (respectively PACKET PSI STATUS) twice.
When the network receives the PACKET SI STATUS (respectively PACKET PSI STATUS) message indicating that all required system information (respectively packet system information) messages have been received by the mobile station it shall stop timer T3197, start timer T3109 (see 3GPP TS 44.018) and send the CHANNEL RELEASE message on the main DCCH indicating that the mobile station is allowed to continue in packet transfer mode after the release of the RR connection (see 3GPP TS 44.018).

41.5.5.1.2 Test Purpose
To verify that the MS performs the acquisition of system information in response to the PACKET CS RELEASE INDCATION message from the NW with the ENHANCED_DTM_CS_RELEASE_INDICATION indicating that the RR connection is released.
To verify that during the acquisition of system information procedure performed as part of the Enhanced DTM CS Release procedure, the MS sends the PACKET SI STATUS message no more than twice when acquiring the system information and then once more only when all the required system information has been acquired.
To verify that the MS continues to maintain an ongoing uplink TBF throughout the Enhanced DTM CS Release procedure and once the Enhanced DTM CS Release procedure has been completed.
41.5.5.1.3 Method of Test
Initial Conditions
System Simulator:
– 2 cells A and B with the same MCC/MNC/LAC/RAC, Enhanced DTM supported.
Mobile Station:
– The MS is in the active state (U10) of a call on Cell A on timeslot N.
– The MS is in packet idle mode, with a TMSI, P-TMSI allocated and PDP context 1 activated.

Test Procedure
The MS, whilst in dedicated mode, is triggered to initiate packet uplink transfer data in RLC unacknowledged mode and sends a DTM REQUEST message. On receipt of the DTM REQUEST message, requesting uplink resources, the SS assigns the MS PS resource using a PACKET ASSIGNMENT message. Following handover to Cell B, the active speech call is disconnected. The SS sends the PACKET CS RELEASE INDICATION message on PACCH to the MS indicating that the RR connection is going to end. The PACKET CS RELEASE INDICATION indicates that when the RR connection is released the MS maintains it’s downlink and/or uplink TBF(s). The MS responds with the PACKET SI STATUS message on PACCH which indicates the non receipt of the SI1 and SI3 messages. In response the SS sends the PACKET SERVING CELL SI message on PACCH encapsulating the SI1 message. The MS again sends the PACKET SI STATUS message on PACCH which indicates reception of the SI1 message but not the SI3 message. In response the SS sends the PACKET SERVING CELL SI message on PACCH encapsulating the SI13 message. It is checked that the two PACKET SI STATUS messages from the MS are sent at least 1s apart. Finally the SS sends the PACKET SERVING CELL SI message on PACCH encapsulating the SI3 message. The MS responds with the PACKET SI STATUS message indicating receipt of the SI1 and SI3 messages. The SS sends the CHANNEL RELEASE message on the main DCCH indicating in the Enhanced DTM Release Indication IE that the MS may continue in packet transfer mode. It is checked that the MS continues operating the uplink TBF by sending RLC data blocks on the PS resources.

Test Procedure
The MS, whilst in dedicated mode, is triggered to initiate packet uplink transfer data in RLC unacknowledged mode and sends a DTM REQUEST message. On receipt of the DTM REQUEST message, requesting uplink resources, the SS assigns the MS PS resource using a PACKET ASSIGNMENT message which also assigns a new downlink TBF. The active speech call is disconnected. The SS sends the PACKET CS RELEASE INDICATION message on PACCH to the MS indicating that the RR connection is going to end. The PACKET CS RELEASE INDICATION indicates that when the RR connection is released the downlink and/or uplink TBFs are reconfigured and reassigns the uplink and downlink TFIs as well as the allocated timeslots. Once any requested SI messages have been sent to the MS, the SS sends the CHANNEL RELEASE message on the main DCCH indicating in the Enhanced DTM Release Indication IE that the MS may continue in packet transfer mode. It is checked that the MS continues operating the uplink and downlink TBFs by sending RLC data blocks on the new PS resources.

Test Procedure
The MS, whilst in dedicated mode, is triggered to initiate packet uplink data transfer in RLC unacknowledged mode and sends a DTM REQUEST message. On receipt of the DTM REQUEST message, the SS assigns the MS packet switched resources using a PACKET ASSIGNMENT message. Before the MS has completed transmission of the uplink data, the SS orders a handover to Cell B. Following handover to Cell B the non-combined routing area update procedure is performed on the main DCCH. The MS resumes transmission of the uplink data. The active speech call is disconnected. The SS sends the PACKET CS RELEASE INDICATION message on PACCH to the MS indicating that the RR connection is going to end. The PACKET CS RELEASE INDICATION indicates that when the RR connection is released the MS may maintain it’s uplink TBF. The packet switched resources are not re-allocated. The MS responds with the PACKET SI STATUS message on PACCH. The SS sends the MS any requested SI messages encapsulated within PACKET SERVING CELL SI messages on PACCH. The MS responds with the PACKET SI STATUS message indicating receipt of the required SI messages. The SS sends the CHANNEL RELEASE message on the main DCCH indicating in the Enhanced DTM Release Indication IE that the MS may continue in packet transfer mode. It is checked that the MS continues operating the uplink TBF by sending RLC data blocks on the PS resources. The MS requests circuit switched resources by sending the PACKET CS REQUEST on PACCH. The SS responds with the PACKET CS COMMAND on PACCH which encapsulates a DTM ASSIGNMENT COMMAND. The location update procedure is completed on the assigned circuit switched resources. Prior to sending the CHANNEL RELEASE message on the main DCCH, the SS sends the PACKET CS RELEASE INDICATION message on PACCH to the MS indicating that the RR connection is going to end. The PACKET CS RELEASE INDICATION indicates that when the RR connection is released the MS may maintain it’s uplink TBF. The packet switched resources are not re-allocated. The MS responds with the PACKET SI STATUS message on PACCH. The SS sends the MS any requested SI messages encapsulated within PACKET SERVING CELL SI messages on PACCH. The MS responds with the PACKET SI STATUS message indicating receipt of the required SI messages. The SS then sends the CHANNEL RELEASE message on the main DCCH indicating in the Enhanced DTM Release Indication IE that the MS may continue in packet transfer mode. It is checked that the MS continues operating the uplink TBF by sending RLC data blocks on the PS resources.

Following handover to Cell B the non-combined routing area update procedure is performed on the main DCCH. The MS resumes transmission of the uplink data. The active speech call is disconnected. The SS sends the PACKET CS RELEASE INDICATION message on PACCH to the MS indicating that the RR connection is going to end. The PACKET CS RELEASE INDICATION indicates that when the RR connection is released, the MS may maintain the uplink TBF. The packet switched resources are not re-allocated. The MS responds with the PACKET SI STATUS message on PACCH in which it requests the release of both packet and circuit switched resources. The SS responds with the CHANNEL RELEASE message which indicates that the MS may not continue in packet transfer mode. It is checked that the MS no longer transmits data on the previously assigned packet switched resources. The MS requests packet switched resources in order to perform the Combined Routing Area update procedure. Following completion of the Combined Routing Area Update procedure the MS requests packet switched resources in order to continue with the transfer of user data.
