A.5.4 Inter-system Handover from UTRAN FDD to GSM
25.1333GPPRelease 17Requirements for support of radio resource management (FDD)TS
A.5.4.1 Test Purpose and Environment
This test is to verify the requirement for the UTRAN to GSM cell handover delay reported in section 5.4.2.1.
The test parameters are given in Table A.5.0D, A.5.0E and A.5.0F below. In the measurement control information it is indicated to the UE that event-triggered reporting with Event 3C shall be used.. The test consists of three successive time periods, with a time duration of T1, T2 and T3 respectively. At the start of time duration T1, the UE may not have any timing information of cell 2.
The UTRAN shall send a Handover from UTRAN command with activation time "now" with a new active cell, cell 2. In the GSM Handover command contained in that message, the IE starting time shall not be included. The RRC HANDOVER FROM UTRAN COMMAND message shall be sent to the UE. The start of T3 is defined as the end of last TTI containing the HO command.
The requirements are also applicable for a UE not requiring compressed mode, in which case no compressed mode pattern should be sent for the parameters specified in table A5.0D

A.5.4.2 Test Requirements
The UE shall begin to send access bursts on the new DCCH of the target cell less than 100 ms from the beginning of time period T3.
The rate of correct handovers observed during repeated tests shall be at least 90%.
NOTE: The test requirement in this test case is expressed as:
THandover delay = 90 ms (Table 5.2) + Toffset + TUL
Toffset : Equal to 4.65 ms, GSM timing uncertainty between the time from when the UE is ready to transmit until the start of the next timeslot in GSM 26 multiframe structure
TUL: Equal to 4.65 ms, the time the UE has to wait in case the next timeslot is an idle frame or a SACCH frame.
This gives a total of 99.3 ms, allow 100 ms in the test case.
A.5.4a Inter-system Handover from UTRAN FDD to E-UTRAN FDD
A.5.4a.1 Test Purpose and Environment
This test is to verify the requirement for the UTRAN FDD to E-UTRAN FDD handover requirements specified in section 5.4a.
The test parameters are given in Table A.5.0G, A.5.0H and A.5.0I below. In the measurement control information it is indicated to the UE that event-triggered reporting with Event 3A shall be used. The test consists of three successive time periods, with time durations of T1, T2 and T3 respectively. At the start of time duration T1, the UE does not have any timing information of Cell 2. Starting T2, Cell 2 becomes detectable and the UE is expected to detect and send a measurement report.
The UTRAN shall send a Handover from UTRAN command with activation time "now" with a new active cell, cell 2. In the E-UTRAN Handover command contained in that message, the IE starting time shall not be included. The RRC HANDOVER FROM UTRAN COMMAND message shall be sent to the UE. The start of T3 is defined as the end of last TTI containing the HO command.
The requirements are also applicable for a UE not requiring compressed mode, in which case no compressed mode pattern should be sent for the parameters specified in table A.5.0G.
