9.4.7 Location Updating / accept with replacement or deletion of Equivalent PLMN list
34.123-13GPPPart 1: Protocol conformance specificationRelease 15TSUser Equipment (UE) conformance specification
9.4.7.1 Definition
Test to verify that the UE replaces or deletes its stored Equivalent PLMN list when no Equivalent PLMN list is included in the LOCATION UPDATING ACCEPT message from the network during a Location Update.
9.4.7.2 Conformance requirement
1) The stored list in the mobile station shall be replaced on each occurrence of the LOCATION UPDATING ACCEPT message.
2) If no equivalent PLMN list is contained in the LOCATION UPDATING ACCEPT message, then the stored equivalent PLMN list in the mobile station shall be deleted.

9.4.7.3 Test purpose
- To verify that the UE replaces its stored equivalent PLMN list if the equivalent PLMN list is contained in the LOCATION UPDATING ACCEPT message received from the network during a location updating procedure.
2) To verify that the UE deletes its stored equivalent PLMN list if no equivalent PLMN list is contained in the LOCATION UPDATING ACCEPT message received from the network during a location updating procedure.
9.4.7.4 Method of test
Initial conditions:
– System Simulator:
– two cells: A and B, with different PLMN Codes (PLMN 1 and PLMN 2 respectively);
– Qqualmin values for cells A and B are -16 dB (FDD only)
NB: i) Cell B will be mapped to Cell 4 as found in TS 34.108 clause 6.1.4.1.
– User Equipment:
– the UE is switched off. The HPLMN is PLMN 3 and no other information about PLMN priorities or forbidden PLMNs is stored in the USIM. The equivalent PLMN list in the mobile station is empty.
– the UE is "Idle updated" on cell B.

Switch off on button Yes/No.
Test procedure
When the UE is initially switched on it will perform a normal location updating in Cell A, which is the only suitable cell available. The LOCATION UPDATING ACCEPT message sent by the SS on reception of the LOCATION UPDATING REQUEST message shall include PLMN 2 in the equivalent PLMN list. When Cell B is made available and its RF signal level is higher than that of Cell A the UE will perform a normal location updating in this cell. The LOCATION UPDATING ACCEPT message sent by the SS shall include PLMN 1 in the equivalent PLMN list. When Cell B is made unavailable the UE shall perform a normal location updating again in Cell A, but in this occasion the LOCATION UPDATING ACCEPT message shall contain an empty equivalent PLMN list. When Cell B is made available again and its RF signal level is higher than that of Cell A the UE shall not perform a normal location updating in this cell since it is not in the ePLMN list.
