Test Procedure
The MS is triggered to initiate packet uplink transfer 2000 octets in the RLC acknowledged mode on cell A. After a successful uplink PDCH assignment the SS sends PACKET DOWNLINK DUMMY indicating the assigned USF assigned to the MS. The MS sends a RLC radio block. The SS allows the MS to transfer about 30 RLC blocks.
The SS provides the MS a minimum set of System Info Types in order to perform a A/Gb to A/Gb synchronized PS Handover by sending them in PACKET NEIGHBOUR CELL DATA message.
The SS sends PS HANDOVER COMMAND to assign a PDCH on cell B. The MS moves to cell B and resumes the uplink data transfer. The MS completes the uplink data transfer.
Maximum Duration of Test
5 minutes.

A mobile station operating in A/Gb mode shall consider the PS handover to A/Gb mode to have failed for the following reasons:
- Timer T3218 expires while in the new cell.
A mobile station operating in A/Gb mode when a PS handover to A/Gb mode fails shall proceed as follows:
- If timer T3218 expired it shall return to the cell on which the PS HANDOVER COMMAND message was received.
- Send a Packet Cell Change Failure message with the cause code set to "No response on target cell" if timer T3218 or T3216 expired, otherwise "PS Handover failure-others". The message shall be sent on PACCH .
- The transmission of a Packet Cell Change Failure message terminates the PS handover procedure in the mobile station and after the transmission of this message the mobile station is therefore allowed to request the establishment of additional uplink TBFs.
- After terminating the PS handover procedure the mobile station shall resume all uplink and downlink TBFs that were ongoing in the old cell prior to receiving the PS HANDOVER COMMAND message. Timers T3180 (uplink TBFs) and T3190 (downlink TBFs) corresponding to these TBFs shall be re-started.
- For each TBF that is resumed the corresponding RLC state machine shall reflect its state when the last RLC data block was transmitted for that TBF in the old cell (uplink TBFs) and the last RLC data block was received for that TBF in the old cell (downlink TBFs).

683b5b8a98f7b1390ddd5516ea9247a2 | 51.010-1 | 41.6.2.1.1 Conformance requirements | The following synchronisation mechanisms are used for PS handover:
• Non-synchronised.
• Synchronised.
• Pre-Synchronised.
The synchronised and pre-synchronised cases are shown in figures 23 and 25 and have different mechanisms for the provision of the timing advance that are described in 3GPP TS 45.010 [26].
NOTE: The pseudo-synchronised case is not supported by the PS handover feature.
In the case of pre-synchronised handover the MS may receive the timing advance information to use in uplink in the target cell in the PS Handover Command message (if no timing advance information is included, the mobile station uses a default timing advance in the target cell). In a pre-synchronised or synchronised handover, the Packet Physical information message is not sent in the target cell.
If the timing advance with the new cell calculated by the mobile station is not out of range, i.e. smaller than or equal to the maximum timing advance that can be coded as specified in 3GPP TS 44.004, or if the new cell does accept out of range timing advance as indicated in the PS HANDOVER COMMAND message, the mobile station acts on the message.
After having switched to the assigned channels, if the Handover Reference information is included within the PS HANDOVER COMMAND message the mobile station shall send four times the PS HANDOVER ACCESS message.
The mobile station activates the channels in sending and receiving mode. The MS may activate the channels in downlink while sending access bursts.
If the PS HANDOVER COMMAND indicates RLC reset for a TBF allocated in the new cell corresponding to a PFC receiving a PS handover, the target BSS shall initialize a new RLC entity to support that TBF. Otherwise, the TBF allocated in the new cell shall be supported using the same RLC entity used to support the TBF in the old cell corresponding to the same PFC (i.e. the RLC state machine is maintained across PS handover).

683b5b8a98f7b1390ddd5516ea9247a2 | 51.010-1 | 41.6.3.1.1 Conformance requirements | The following synchronisation mechanisms are used for PS handover:
- Non-synchronised.
- Synchronised.
- Pre-Synchronised.
The non-synchronised cases are shown in figures 22 and 24 and are characterised by the requirement for the MS to obtain a valid uplink timing advance before it can transmit normal bursts. The MS shall notify its presence in the target cell through the transmission of access bursts to the BSS, and the BSS shall respond with a valid timing advance which in turn enables the MS to send normal bursts in uplink.
After having switched to the assigned channels, the mobile station shall send four times the PS HANDOVER ACCESS message. The mobile station shall start timer T3216 at the start point of the timeslot in which the PS HANDOVER ACCESS message is sent the first time on the PACCH.
If the network requests the transmission of the PS HANDOVER ACCESS message it shall be sent with highest transmission priority using either the 8-bit or 11-bit access burst format on the PACCH associated with any uplink TBF allocated in the PS HANDOVER COMMAND message for which the mobile station detects an assigned USF value. Its content consists of the handover reference field. The burst format used shall be that specified by the ACCESS_BURST_TYPE in the system information for the target cell.
The mobile station then activates the channels in receiving mode.
Upon reception of the PS HANDOVER ACCESS message containing the expected Handover Reference value, once the network has the RF characteristics that are necessary, it sends a PACKET PHYSICAL INFORMATION message to the mobile station on the PACCH.
When the mobile station receives a PACKET PHYSICAL INFORMATION message, it stops timer T3216, stops sending access bursts and activates the channels in sending and receiving mode.
The MS sends uplink LLC PDUs, e.g. a Routing Area Update Request message or uplink user data packets to the SGSN immediately after receiving the Packet Physical Information message or, in a synchronised or pre-synchronised handover, immediately if the PS Handover Access message is not required to be sent (see Section 6.2).

Test Procedure
The MS is triggered to initiate packet uplink transfer 2000 octets in the RLC acknowledged mode on cell A. After a successful uplink PDCH assignment the SS sends PACKET DOWNLINK DUMMY indicating the assigned USF to the MS. The MS sends a RLC radio block. The SS allows the MS to transfer about 30 RLC blocks.
The SS provides the MS a minimum set of System Info Types in order to perform a A/Gb to A/Gb Non-synchronized PS Handover to cell B by sending them in PACKET NEIGHBOUR CELL DATA message.
The SS sends PS HANDOVER COMMAND to assign a PDCH on cell B and containing a handover reference. The MS moves to cell B and sends PS HANDOVER ACCESS in 11-bit access burst format in Cell B. The SS sends PACKET PHYSICAL INFORMATION to the MS.
Following handover to Cell B MS continues with the data uplink data transfer in Cell B. The SS allows the MS to transfer about 30 RLC blocks.

683b5b8a98f7b1390ddd5516ea9247a2 | 51.010-1 | 41.6.3.3.1 Conformance requirements | In case of initial access failure in the target cell, including the case where the MS fails to acquire time alignment information (for the unsynchronised network case), the MS is allowed to revert to the old cell. As is defined currently in 3GPP TS 44.060 [7], the MS shall return to the old cell and send a Packet Cell Change Failure message with the appropriate cause.
If the MS was in packet transfer mode (or MAC-shared state) before the attempted handover it will, when going back to the old cell, send a Packet Cell Change Failure message and resume TBFs which were ongoing in the old cell.
A mobile station operating in A/Gb mode shall consider the PS handover to A/Gb mode to have failed for the following reasons:
- Timer T3216 expires while in the new cell.
A mobile station operating in A/Gb mode when a PS handover to A/Gb mode fails shall proceed as follows:
- If timer T3216 expired it shall return to the cell on which the PS HANDOVER COMMAND message was received.
- Send a Packet Cell Change Failure message with the cause code set to "No response on target cell" if timer T3218 or T3216 expired, otherwise "PS Handover failure-others". The message shall be sent on PACCH .
- The transmission of a Packet Cell Change Failure message terminates the PS handover procedure in the mobile station and after the transmission of this message the mobile station is therefore allowed to request the establishment of additional uplink TBFs.
- After terminating the PS handover procedure the mobile station shall resume all uplink and downlink TBFs that were ongoing in the old cell prior to receiving the PS HANDOVER COMMAND message. Timers T3180 (uplink TBFs) and T3190 (downlink TBFs) corresponding to these TBFs shall be re-started.
- For each TBF that is resumed the corresponding RLC state machine shall reflect its state when the last RLC data block was transmitted for that TBF in the old cell (uplink TBFs) and the last RLC data block was received for that TBF in the old cell (downlink TBFs).

A mobile station that has enabled PEO (see 3GPP TS 43.064 [109]) shall only transmit an EGPRS PACKET CHANNEL REQUEST message indicating ‘PEO One Phase Access Request’ (see Table 3.5.2.1.2.2 and 3GPP TS 44.060 [76]) when performing system access. A BSS that receives this message shall send a response that only assigns the MS packet resources in the frequency band corresponding to CCCH on which the EGPRS PACKET CHANNEL REQUEST message was received.
[...]
A MS that has enabled PEO where eDRX is used supports eDRX paging cycles that can range from multiple seconds to about 52 minutes (see 3GPP TS 45.002 [32]). In this case the mobile station supports reachability while in packet idle mode as follows:
• The mobile station uses the lowest eDRX cycle while the Ready timer (see 3GPP TS 24.008 [79]) is running.
• Upon expiration of the Ready timer or waking up and determining it has not been paged using its nominal paging group the mobile station re-enters the eDRX based power saving state for the time remaining until its next paging occasion.

Test procedure
The MS is triggered to initiate the GPRS attach procedure on a PEO (eDRX) capable Cell The SS verifies that the MS uses an EGPRS PACKET CHANNEL REQUEST message indicating ‘PEO One Phase Access Request’ for every packet access when the PEO is enabled (ATTACH_ACCEPT received). Only the eDRX value is sent by the SS.
Once the device is GPRS attached, in packet idle mode with the Ready Timer running, the SS pages the MS according to the second lowest eDRX cycle and reject the MS access. The MS is then pages according to the second lowest eDRX cycle, once the ready timer is expired. There should be no answer from the MS.
The MS is then paged according to its negotiated eDRX cycle and should answer the Paging Request.

If PSM has been negotiated (see 3GPP TS 24.008 [51]) it starts the active timer upon expiration of the ready timer. While the active timer is running it remains reachable using the eDRX value last negotiated with the network. If no eDRX value has been negotiated then it uses the DRX cycle applicable to the serving cell while the Active timer is running. When the active timer expires the mobile station enters the PSM based power saving state and will not be reachable until the next time it performs an uplink data transfer.

Test Procedure
The MS is triggered to transfer user data. A TBF using dynamic allocation in acknowledged mode is assigned. The SS assigns an USF to MS. SS receives data blocks till CV=0 and acknowledges all the blocks with an UPLINK ACK/NACK setting FAI=0. Then SS checks that if a USF is matched to the MS it sends a UPLINK DUMMY CONTROL BLOCK. SS sends two PACKET TIMESLOT RECONFIGURE, reassigning the timeslot given for Uplink and initiating a downlink TBF on both new defined slot.
One PACKET TIMESLOT RECONFIGURE is sent out of the blocks defined by the Conformance Requirements. SS checks that the MS is not sending an UPLINK DUMMY CONTROL BLOCK on the new channels whenever the USF is matched. This is to verify that the PACKET TIMESLOT RECONFIGURE was not taken into account.
The other PACKET TIMESLOT RECONFIGURE is sent on the blocks defined by the Conformance Requirements. SS checks that the MS is sending an UPLINK DUMMY CONTROL BLOCK on the new channels whenever the USF is matched. This is to verify that the PACKET TIMESLOT RECONFIGURE was taken into account.
SS releases the downlink TBF.

Reference
3GPP TS 44.018 subclause 3.10.4
A mobile station that has enabled EC operation uses its currently estimated uplink coverage class to determine the number of blind physical layer transmissions to use when sending an EC PACKET CHANNEL REQUEST message (see sub-clause 3.5.2a) and includes an estimate of its downlink coverage class in the message (see sub-clause 9.1.65).
Reference
3GPP TS 44.018 subclause 3.10.5
On receipt of an EC-IMMEDIATE ASSIGNMENT TYPE 2 message corresponding to its last EC PACKET CHANNEL REQUEST message, the mobile station stops T3146 (if running), stops sending EC PACKET CHANNEL REQUEST messages, and switches to the assigned PDCH(s).

The EC-BCCH CHANGE MARKfield is set updated to 001’ in EC-SCH. The parameter EC_MAX_RETRANS is changed to 2 retransmissions in EC-SI 2.
The MS is triggered to send uplink data (2 MCS-1 coded RLC data blocks using normal priority). The MS checks the EC-BCCH CHANGE MARK on EC-SCH, notices the change and re-acquires the EC System Information Type 2 message.
The MS then sends an EC PACKET CHANNEL REQUEST.
The SS ignores first EC PACKET CHANNEL REQUEST message and acts on the second EC PACKET CHANNEL REQUEST message (verifies that 2 retransmissions of the EC PACKET CHANNEL REQUEST are done)

Test Procedure
The MS is triggered to initiate the GPRS attach procedure on an EC-GSM-IoT capable Cell but does not include eDRX or PSM related parameters in the GPRS Attach Request. The SS checks that the MS does not indicate any value for eDRX.
Once the device is GPRS attached, in packet idle mode with Ready Timer expired the SS pages the MS according to the lowest eDRX cycle. There should be no answer from the MS as the MS has not negotiated the use of an eDRX cycle (i.e. the MS is unreachable when the neither the Ready timer nor Active timer is running).
The MS is then paged according to the lowest eDRX cycle and should answer the Paging Request. The Paging request contains the EC-GSM-IoT Page Extension IE set to CC1. The SS reject the MS access.
The MS is then paged according to the second lowest eDRX cycle and should answer the Paging Request.

Test Procedure
The MS is triggered to initiate the GPRS attach procedure on an EC-GSM-IoT (eDRX & PSM) capable Cell. The MS send either eDRX only or both PSM and eDRX values in the ATTACH REQUEST.
Either eDRX or both PSM and eDRX values are sent by the SS, depending on what the MS sent in the ATTACH REQUEST, as well as the DL CC received by the SS during the GPRS attach procedure (i.e. EC operation is enabled). The eDRX value shall not be the lowest eDRX value but shall be selected so that only one eDRX cycle fits within the time period determined by the Active timer (T3324).
Once the device is GPRS attached, in packet idle mode with Ready Timer expired the SS pages the MS according to the lowest eDRX cycle. There should be no answer from the MS as the eDRX cycle negotiated is higher.
The MS is then paged according to its negotiated eDRX cycle and should answer the Paging Request. The SS reject the MS access.
When the T3324 timer expire the MS is paged according to its negotiated eDRX cycle. If the MS indicated that PSM is supported there should be no answer from the MS.
Maximum Duration of Test

Note 1: PG (Paging Group) represents the start of the coverage class specific EC-PCH block corresponding to the nominal paging group of an MS (see 3GPP TS 45.002 [32]). The start of the coverage class specific EC-PCH block used for page extension is expressed as an offset relative to PG (where the value of the offset indicates the number of coverage class specific EC-PCH blocks comprising the offset).
Note 2: Page Extension is determined using PG + 2 when a CC2 MS reading its nominal paging group in TDMA frames 35 to 42 (CC2 B2) or in TDMA frames 43 to 50 (CC2 B3) in MF N/N+1 determines that a CC4 page is ongoing from TDMA frames 35 to 50 in MF N/N+1/N+2/N+3.

An immediate assignment, not addressing the MS, is sent on the MS paging group with the EC Page Extension field enabled for the selected DL Coverage class of the MS. The MS is then paged on the fixed offset paging block according to its selected DL coverage class and shall answer the paging.
At the next paging occurrence, a new Paging request not addressing the MS is sent with the EC Page Extension field enabled for a coverage class different than the MS one. The SS verified that it is not taken into account by the MS with a new Paging request addressing the MS on the fixed offset paging block according to its selected DL coverage class,.
The procedure is repeated for all the DL coverage class (k= 1 to 4).
