27.9 MS recognizing the priority order of the PLMN selector list
3GPP51.010-1Mobile Station (MS) conformance specificationPart 1: Conformance specificationTS
27.9.1 Definition
The PLMN selector list gives in priority order the preferred PLMNs on which the MS shall register. The list is stored on the SIM in the EFPLMNsel. Update and deletion of PLMNs may be performed by the subscriber by the use of the PIN.
27.9.2 Conformance requirement
When registering onto a VPLMN the MS shall take into account the priority order of the PLMNs in the preferred list on the SIM.
3GPP TS 02.11, subclause 3.2.2.2.
27.9.3 Test purpose
To verify that the PLMN with the higher priority (defined by its position in EFPLMNsel) takes precedence over the PLMN with the lower priority when the MS performs a network selection.
27.9.4 Method of test
27.9.4.1 Initial conditions
The SS transmits on two BCCHs, with the following network parameters:

The SIM is installed into the ME and the MS is set to automatic PLMN selection mode.
27.9.4.2 Procedure
a) The MS is powered on.
b) After receipt of a CHANNEL REQUEST from the MS, the SS sends IMMEDIATE ASSIGNMENT to the MS.
c) After receipt of a LOCATION UPDATE REQUEST from the MS, the SS sends LOCATION UPDATE ACCEPT with:
LAI-MCC: 234
LAI-MNC 34 or 345 (see Note 0)
TMSI: "34567890".
to the MS
d) After receipt of a TMSI REALLOCATION COMPLETE from the MS, the SS sends CHANNEL RELEASE to the MS.
e) The MS is soft powered down.
27.9.5 Test requirement
1) After step b) the MS shall send LOCATION UPDATE REQUEST containing an MCC/MNC of 234/34 or 234/345 (see Note 0) to the SS.
2) After step c) the MS shall respond with TMSI REALLOCATION COMPLETE.
3) After step e) the SIM shall contain the following values:
EFLOCI (Location Information)
Logically: LAI-MCC: 234
LAI-MNC: 34 or 345 (See Note 0)
TMSI: "34567890"
