Equation 1:
3> store in the variable BEST_CELL_3D_EVENT the EARFCN and Physical Cell Identity of the E-UTRA
cell that has the best measured quantity among the EARFCNs considered in that inter-RAT measurement;
3> send a measurement report with IE set as below:
4> set in "E-UTRA measurement results": "inter-RAT event identity" to "3d", and "E-UTRA Carrier
Frequency" and "Physical Cell Identity" to the EARFCN and the Physical Cell Identity that are stored
in the variable BEST_CELL_3D_EVENT;
4> set the IE "E-UTRA measured results" according to subclause 8.6.7.5.
2> if equation 1 below has been fulfilled for a time period indicated by "time to trigger" for a cell on one of the
EARFCNs considered in that inter-RAT measurement and different from the cell stored in
BEST_CELL_3D_EVENT:
M ≥ M + H
New
Best
3> store the EARFCN and Physical Cell Identity of that E-UTRA cell in the variable
BEST_CELL_3D_EVENT;
3> send a measurement report with IEs set as below:
4> set in "E-UTRA event results": "inter-RAT event identity" to "3d", and "E-UTRA carrier frequency"
and "Physical Cell Identity" to the EARFCN and the Physical Cell Identity that are now stored in the
variable BEST_CELL_3D_EVENT;
4> set the IE "E-UTRA measured results" according to subclause 8.6.7.5.

/2
The variables in the formula are defined as follows:
M New is the measurement quantity for a cell of the other system that is not stored in the variable
BEST_CELL_3D_EVENT.
M Best is the measurement quantity for a cell of the other system that is stored in the variable
BEST_CELL_3D_EVENT.
H 3d is the hysteresis parameter for event 3d.
14.3.2 GSM measurements in compressed mode
14.3.2.1 GSM RSSI measurements
The UE shall perform GSM RSSI measurements in the gaps of compressed mode pattern sequence specified for GSM
RSSI measurement purpose.
14.3.2.2 Initial BSIC identification
The UE shall perform Initial BSIC identification in compressed mode pattern sequence specified for Initial BSIC
identification measurement purpose.
The parameter "N identify abort" in the IE "DPCH compressed mode info" indicates the maximum number of patterns
that the UE shall use to attempt to decode the unknown BSIC of the GSM cell in the initial BSIC identification
procedure.
The BSIC identification procedure is defined in detail in [19].
14.3.2.3 BSIC re-confirmation
The UE shall perform BSIC re-confirmation in compressed mode pattern sequence specified for BSIC re-confirmation
measurement purpose.
