8.12 Pre- and postambles for GERAN to UTRAN tests
34.123-33GPPPart 3: Abstract test suite (ATS)TSUser Equipment (UE) conformance specification
8.12.1 Preamble for GERAN to UTRAN tests
Before running inter-RAT test cases, radio conditions should be such that the mobile has to select the cell of the intended original RAT. The following steps should be used before running GERAN to UTRAN test cases.
1. UTRAN cell is powered OFF. The default radio conditions for a suitable GERAN cell are used for the serving cell, as defined in 3GPP TS 34.108 [3], clause 6.1.7. This step is performed while the UE is still switched OFF.
2. UE is switched ON and performs registration and attach.
3. The UTRAN cell is powered ON with an RF level such that the cell is a suitable neighbour cell, using the RF conditions defined in 3GPP TS 34.108 [3], clause 6.1.5, so that the UE will not re-select the UTRAN cell.
8.12.2 Postamble for GERAN to UTRAN tests
The following procedure is used after inter-RAT handover or cell change order test cases in case the test needs to be performed multiple times in a loop.
8.12.2.1 GERAN to UTRAN handover in CS
The test cases are defined in 3GPP TS 51.010-1 [26], clause 60.
