42.4.2.1 Cell change order procedure / Uplink transfer

42.4.2.1.1 Cell change order procedure / Uplink transfer / Normal case

42.4.2.1.1.1 Conformance requirement

The cell change order procedure is started by sending a PACKET CELL CHANGE ORDER message to the mobile station on the PCCCH or PACCH. Upon receipt of the PACKET CELL CHANGE ORDER message the mobile station shall start timer T3174.

When a cell reselection is made controlled by the network, the mobile station shall act upon the IMMEDIATE_REL value which has been received in the Packet Cell Change Order: if required, the mobile station shall abort any TBF in progress by immediately ceasing to decode the downlink, ceasing to transmit on the uplink, stopping all RLC/MAC timers except for timers related to measurement reporting. The mobile station shall then switch to the identified specified new cell and shall obey the relevant RLC/MAC procedures on this new cell.

42.4.2.1.1.2 Test Purpose

To verify the when NC2 is commanded, the MS sends PACKET MEASUREMENT REPORT messages, in which both the serving and non-serving cells are reported.

To verify that when the cell change order procedure is started by sending a PACKET CELL CHANGE ORDER message with the IMMEDIATE_REL value set to 1, the MS shall abort any TBF in progress and stop transmitting.

To verify that the MS shall switch to the new cell.

Foreseen final state of the MS

– MS is in transfer mode.

Test procedure

MS is brought into uplink packet transfer mode. SS commands MS to NC2 with PACKET MEASUREMENT ORDER. SS waits for a PACKET MEASUREMENT REPORT to contain measurement results for both cell A and cell B. SS sends a PACKET CELL CHANGE ORDER message. SS checks that there is no traffic on the old cell. MS switches to the new cell and re-establishes the uplink TBF.

42.4.2.1.4.1.1 Conformance requirement for Rel-5 and earlier

If the contention resolution procedure fails on the new cell, then the mobile station shall start timer T3176 and return to the old cell. The mobile station shall send a PACKET CELL CHANGE FAILURE message to the network.

References

3GPP TS 04.60/44.060, subclause 8.4.1

42.4.2.1.4.1.2 Conformance requirement for Rel-6 and later

The mobile station shall regard the network controlled cell reselection procedure as successfully completed when it has performed access and successfully completed contention resolution in the new cell.

In the following cases, the mobile station shall determine that the network controlled cell reselection procedure has failed:

– The mobile station is unable to synchronise to the new cell (see 3GPP TS 45.008) or the timer T3174 expires before a successful completion of the network controlled cell reselection procedure. Cause: ‘No response on target cell’.

If the mobile station determines that the network controlled cell reselection procedure has failed, the mobile station shall stop timer T3174 (if it is still running) and start timer T3176. The mobile station shall return to the old cell, where it may trigger a cell update or other GMM specific procedure. In case the mobile station synchronised and attempted to access the new cell before returning to the old cell, the mobile station shall trigger a cell update or other GMM specific procedure, as appropriate according to the GMM requirements (see 3GPP TS 24.008).

The mobile station shall send a PACKET CELL CHANGE FAILURE message with the appropriate cause value to the network in the old cell and stop timer T3176. The PACKET CELL CHANGE FAILURE message may be sent on PACCH when the mobile station is in packet transfer mode or MAC-Shared state. Alternatively, the mobile station may initiate random access with access type ‘single block without TBF establishment’ (PCCCH) / ‘single block packet access’ (CCCH) and send the PACKET CELL CHANGE FAILURE message using an allocated single uplink block.

Test procedure

The MS is brought into downlink packet transfer mode on carrier 1 in Cell A. The SS sends a PACKET MEASUREMENT ORDER message, setting NETWORK_CONTROL_ORDER to NC2. The SS raises carrier 2 (Cell B) with higher RF signal strength than carrier 1. The MS shall stay camping in the cell A.

42.4.2.3.6.1 Conformance requirements

The behaviour of the mobile station is controlled by the NETWORK_CONTROL_ORDER parameter in a PACKET MEASUREMENT ORDER message. The reporting periods are indicated in the NC_REPORTING_PERIOD_T field of the PACKET MEASUREMENT ORDER message. The mobile station shall apply to the timer T3158 the NC_REPORTING_PERIOD_T when in packet transfer mode.

The procedure for NC measurement report sending shall be initiated by the mobile station at the expiry of the NC measurement report interval timer T3158. At expiry of the timer T3158 the mobile station shall restart the timer T3158, perform the measurements and send the PACKET MEASUREMENT REPORT message containing the ‘NC measurement report struct’ on PACCH.

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).

42.4.2.3.7 MT CS establishment whilst in NC2 with a uplink TBF established

42.4.2.3.7.1 Conformance requirements

– 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).

42.4.2.3.7.2 Test purpose

To verify that the MS sends packet measurement reports of the NC measurements according to the indicated reporting periods when T3158 expires. To verify that the MS reacts to CS paging on the PACCH, whilst the MS was in packet transfer mode and NC2, by releasing the uplink TBF and then establishing the RR connection.

42.4.2.3.7.3 Method of test

Initial Conditions

System Simulator:

2 cells, GPRS supported, NMO I activated.

Mobile Station:

The MS is in packet idle mode, with a TMSI, P-TMSI allocated and PDP context 2activated.

NOTE: carrier 2 is activated in order to prevent synchronisation reading suspension due to unsuccessful synchronization attempts.

Specific PICS Statements

– GPRS Release Supported (TSPC_MS_GPRS_RELEASE)

– Support of Immediate Connect (TSPC_AddInfo_ImmConn)

Foreseen final state of the MS

– MS is in RR dedicated mode.

Test Procedure

The MS is brought into packet transfer mode. SS sends a PACKET MEASUREMENT ORDER message. MS sends continuously data blocks and PACKET MEASUREMENT REPORT messages according to the indicated reporting period, before being paged on the PACCH. Upon receipt of the PACKET PAGING REQUEST message, the MS returns to packet idle mode and initiates the establishment of a CS connection.

Maximum Duration of Test

10 minutes
