9.4.8 Location Updating after UE power off

34.123-13GPPPart 1: Protocol conformance specificationRelease 15TSUser Equipment (UE) conformance specification

9.4.8.1 Definition

Test to verify that the UE stores the equivalent PLMN list at UE power off and uses the stored equivalent PLMN list after UE switch on.

9.4.8.2 Conformance requirement

The equivalent PLMN list shall be stored in the mobile station while switched off so that it can be used for PLMN selection after switch on.

TS 24.008 4.4.4.6

9.4.8.3 Test purpose

To verify that the UE stores the equivalent PLMN list at UE switch off and uses the stored equivalent PLMN list after UE switch on.

9.4.8.4 Method of test

Initial conditions

– System Simulator:

– three cells: A, B and C. Cell A belongs to PLMN1 which is HPLMN. Cell B belongs to PLMN2. Cell C belongs to PLMN3. The PLMNs are defined as follows:

Cell

MCC

MNC

PLMN

A

001

01

PLMN1

B

022

002

PLMN2

C

001

03

PLMN3

NB: i) Cell B will be mapped to Cell 4 as found in TS 34.108 clause 6.1.4.2.

ii) Cell C will be mapped to Cell 7 as found in TS 34.108 clause 6.1.4.2.

– User Equipment:

– the UE has a valid TMSI(= TMSI1) and CKSN(= CKSN1). It is "idle updated" on cell B,

– the UE is equipped with a USIM containing default values except for those listed below.

Switch off on button Yes/No.

Test procedure

The UE is switched on and is in idle-updated state on Cell B. Cell A and C are not available. Cell type of Cell A is then changed to make it available, cell types of Cell B are C are changed to make them unavailable. The UE will perform a normal location updating in Cell A, which is the only suitable cell available and belongs to the HPLMN. The LOCATION UPDATING ACCEPT message sent by the SS shall include PLMN2 in the equivalent PLMN list. The UE shall be switched-off. Cell A shall be made unavailable and Cells B and C shall be made available. When the UE is switched-on again, the UE shall perform a normal location updating in Cell B and not in Cell C because PLMN2 is stored in the UE equivalent PLMN list.
