41.7.1.1 Macros

In order to simplify the process of writing and coding test cases, macros are referenced in the expected signalling tables. These macros provide all additional signalling needed to complete the particular test but are not relevant to its purpose.

41.7.1.2 GPRS Attach Procedure for PEO

The following table describes a signalling sequence performing the GPRS attach procedure for an MS that supports PEO and is performing NAS signalling in an attempt to enable a power saving feature (i.e. eDRX or PSM – see 3GPP TS 23.060 [19]) while in a cell that supports PEO.

The macros {Completion of GPRS attach for PEO} in the test cases refer to the table below starting at the step required for the particular sequence.

41.7.2 Paging

41.7.2.1 PEO Paging / Ready Timer Expiration

41.7.2.1.1 Conformance requirements

A PEO capable mobile station camping in a cell that supports PEO performs NAS signalling to negotiate the use of a power saving feature (i.e. eDRX or PSM – see 3GPP TS 23.060 [74]). 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.

Reference

3GPP TS 44.018 subclauses 3.9.1 & 3.9.2

41.7.2.1.2 Test purpose

1. To verify that a MS that has enabled PEO (eDRX) on a PEO capable cell will use an EGPRS PACKET CHANNEL REQUEST message indicating ‘PEO One Phase Access Request’.

2. To verify that the eDRX cycle negotiated is only applied once the Ready Timer expires. Before that the lowest eDRX cycle is used.

Initial conditions

System Simulator:

1 cell, PEO capable for eDRX.

Mobile Station:

The MS is switched off.

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.

41.7.2.2 PEO Paging / PSM and eDRX

41.7.2.2.1 Conformance requirements

A PEO capable mobile station camping in a cell that supports PEO performs NAS signalling to negotiate the use of a power saving feature. After successfully negotiating a power saving feature or while performing NAS signalling in an attempt to enable a power saving feature (i.e. eDRX or PSM – see 3GPP TS 23.060 [74]) while in a cell that supports PEO, the mobile station 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 only assign the MS packet resources in the frequency band corresponding to CCCH on which the EGPRS PACKET CHANNEL REQUEST message was received.

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.

41.7.2.3 PEO Paging / PEO_BCCH_CHANGE_MARK

41.7.2.3.1 Conformance requirements

An MS that has enabled PEO and is using eDRX shall ignore the “Paging reorganization” condition indicated by the page mode information element if received in any message (i.e. this condition targets mobile stations not using eDRX).

[…]

A MS that has enabled PEO not accessing the network for the purpose of NAS signalling low priority shall also listen to the downlink CCCH until successfully decoding one of the RR messages listed in sub-clause 3.3.1.1.1a and read the PEO_BCCH_CHANGE_MARK field therein. If a change of PEO_BCCH_CHANGE_MARK is detected then it shall first read SI13 prior to performing the packet access.

Reference

3GPP TS 44.018 subclauses 3.5.1.1 & 3.5.2.1.2

41.7.2.3.2 Test purpose

1. To verify that a MS that has enabled PEO will not take into account the “paging Reorganisation” condition indicated by the page mode information.

2. To verify that a MS that has enabled PEO will read the SI13 prior to performing a packet access if a change of the PEO_BCCH_CHANGE_MARK is detected.

41.7.3.1 PEO / Extended UL TBF

41.7.3.1.1 Conformance requirements

An exception case is where a mobile station has enabled PEO or EC-EGPRS in which case it shall operate as follows:

[…]

– If a mobile station that has enabled PEO enters extended uplink TBF mode (see sub-clauses 9.3.1a and 9.3.1b) then it monitors the downlink PACCH starting with the 8th 52-multiframe following the 52-multiframe in which it received the PACKET UPLINK ACK/NACK message confirming reception of all uplink RLC data blocks. More specifically, it monitors radio block [(IMSI mod 1e7) mod 12] in that 52-multiframe and in each subsequent 52-multiframe for a matching PACCH message for as long as it remains in extended UL TBF mode or it receives a matching PACCH message.

Reference

3GPP TS 44.060 subclause 5.5.1.5

41.7.3.1.2 Test purpose

To verify that an MS that has enabled PEO (eDRX) and enters Extended uplink TBF mode will only monitors its assigned PACCH when all uplink RLC data blocks are received by the network

41.7.3.1.3 Method of test

Initial conditions

System Simulator:

1 cell, PEO capable for eDRX, NW_EXT_UTBF = 1.

Mobile Station:

MS is in Packet Idle mode, GPRS attached with support of GERAN Feature Package 1 indicated in MS Radio Access Capabilities, and PDP context 2 established. eDRX negotiated to 52 MF (~12.2 sec)

Specific PICS Statements

PIXIT Statements

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.
