44.2.7 GMM READY timer handling

3GPP51.010-1Mobile Station (MS) conformance specificationPart 1: Conformance specificationTS

The READY timer, T3314 is used in the MS and in the network per each assigned P-TMSI to control the cell updating and paging procedure.

When the READY timer is running the MS shall perform cell update each time a new cell is selected (see 3GPP TS 03.22 [3]). If a routing area border is crossed a routing area updating procedure shall be performed instead of a cell update.

44.2.7.1 Conformance requirement

1) When the READY timer is running the MS shall perform cell update each time a new cell is selected.

2) The READY timer shall be restarted in the MS when the GMM entity receives an indication from lower layers that user data or GMM or SM signalling messages have been transmitted.

3) The READY timer shall be stopped when force to standby is received in a signalling message from the network, after successful completion of the signalling procedure.

4) if the negotiated READY timer value indicates that the ready timer function is deactivated, then the MS shall behave as if READY timer never expires (i.e. the MS remains in READY state all the time).

5) If the READY timer length is set to zero, the MS shall immediately be forced into STANDBY state .MS shall not perform cell update.

Reference(s):

3GPP TS 04.08 / 3GPP TS 24.008 subclause 4.7.2.1.

44.2.7.2 Test Purpose

To verify the functionality of the READY timer.

44.2.7.3 Method of test

44.2.7.3.1 Test procedure 1

Initial conditions

System Simulator:

Two cells (not simultaneously activated), cell A in MCC1/MNC1/LAC1/RAC1, cell B in MCC1/MNC1/LAC1/RAC1.

Both cells are operating in network operation mode II.

Mobile Station:

The MS has a valid IMSI.. MS is Idle Updated on cell A.

Specific PICS statements:

– Switch off on button (TSPC_Feat_OnOff).

– Automatic GPRS attach procedure at switch on or power on (TSPC_AddInfo_on_auto_GPRS_AP).

PIXIT statements:

Test procedure

An attach is performed. The SS negotiates T3314. The MS selects a new cell within the old RA. A cell update is performed.
