9.4.6 Location updating / interworking of attach and periodic
34.123-13GPPPart 1: Protocol conformance specificationRelease 15TSUser Equipment (UE) conformance specification
9.4.6.1 Definition
9.4.6.2 Conformance requirement
1) If the UE is in service state NO CELL AVAILABLE, LIMITED SERVICE, PLMN SEARCH or PLMN SEARCH-NORMAL SERVICE when the timer T3212 expires the location updating procedure is delayed until this service state is left.
2) The T3212 time-out value shall not be changed in the NO CELL AVAILABLE, LIMITED SERVICE, PLMN SEARCH and PLMN SEARCH-NORMAL SERVICE states.
3) If the selected cell is in the location area where the UE is registered and IMSI ATTACH is not required and timer T3212 has not expired, then the state is NORMAL SERVICE.

9.4.6.3 Test purpose
1) To check that if the PLU timer expires while the UE is out of coverage, the UE informs the network of its return to coverage.
2) To check that the PLU timer is not disturbed by cells of forbidden PLMNs.
3) To check that if the PLU timer does not expire while out of coverage and if the mobile returns to the LA where it is updated, the UE does not inform the network of its return to coverage.
9.4.6.4 Method of test
Initial conditions
– System Simulator:
– two cells, a and b, of different PLMNs;
– T3212 is set to 12 minutes on cell a;
– T3212 is set to 6 minutes on cell b;
– IMSI attach is allowed in both cells.
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 deactivated. The PLMN of cell b is entered in the USIM’s forbidden PLMN list.
Related ICS/IXIT statements
None.
Test procedure
The UE is activated and placed in automatic network selection mode. It performs IMSI attach. 1 minute after the end of the IMSI attach procedure, cell a is made unavailable. The UE shall not location update on cell b. 8 minutes after the end of the IMSI attach procedure, cell a is made available. The UE shall not location update on cell a before 11,75 minutes after the end of the IMSI attach procedure. The UE shall perform a periodic location update on cell a between 11,75 minutes and 12,25 minutes after the end of the IMSI attach procedure.
3 minutes after the end of the periodic location updating procedure, cell a is made unavailable. The UE shall not location update on cell b. 14 minutes after the end of the periodic location updating procedure, cell a is made available and cell b is made unavailable. The UE shall perform a location update on cell a before 17 minutes after the end of the periodic location updating procedure.
