27.6 MS updating forbidden PLMNs
3GPP51.010-1Mobile Station (MS) conformance specificationPart 1: Conformance specificationTS
27.6.1 Definition
A list of forbidden PLMNs stored in the SIM provides storage for up to 4 entries, and is managed by the MS. In automatic PLMN selection mode the MS controls location updating attempts to appropriate networks with respect to this list of forbidden PLMNs. As a result of a location update reject with the cause "PLMN not allowed" the MS stores the PLMN which rejected the update request in the SIM.
27.6.2 Conformance requirement
After the receipt of a LOCATION UPDATE REJECT message with the cause "PLMN not allowed" the MS shall update the EFFPLMN in the SIM.
3GPP TS 02.11, subclause 3.2.2.4.
27.6.3 Test purpose
To verify that the MS correctly updates the EFFPLMN, i.e. fill up existing gaps in the elementary file before overwriting any existing entries.
27.6.4 Method of test
27.6.4.1 Initial conditions
The SS transmits on the BCCH, with the following network parameters:
Attach/detach: disabled.
LAI-MCC: 234
LAI-MNC 03 or 034 (see Note 0)
LAI-LAC: 0001
Access control: unrestricted.
The default SIM is used with the following exception:
Bands using 2-digit MNC (see Note 0) begin

The SIM is installed into the ME and the MS is set to automatic PLMN selection mode.
27.6.4.2 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 REJECT to the MS with the cause "PLMN not allowed", followed by CHANNEL RELEASE.
d) The MS is soft powered down.
27.6.5 Test requirement
1) After step b) the MS shall send LOCATION UPDATE REQUEST to the SS.
2) After step d) the SIM shall contain:
