If Combined Cell Reselection triggering GSM to WCDMA enabled if COEXUMTS=2 defines the frequency, scrambling code and diversity information for a UTRAN neighbouring cell. (MFDDARFCN: 0 to 16383 MSCRCODE: 0 to 511 DIVERSITY: DIV, NODIV)
UMFI (MFDDARFCNMSCRCODEDIVERSITY)
FDDQMIN : defines the minimum threshold for the “quality” measure Ec/No for cell reselection to UTRAN FDDQOFF : defines cell reselection offset to UTRAN cells QSI : defines when the monitoring of UMTS cells will be performed. Quality search indicator Qsearch_I for idle mode. COEXUMTS: used to determine if cell reselection and handovers from GSM to UMTS is allowed
UMTS to GSM
Strategy : Reselection to WCDMA when very bad radio conditions
Ericsson Default Parameters serve TT Strategy For Ericsson 2g BSS: RLSUP:CELL=ALL; This command prints system information UTRAN data for all internal cells in the BSC.
CS CONNECTED MODE GSM to UMTS
Strategy: No HO towards WCDMA terminate voice call in GSM
Value to be implemented 15 (never) 1 (QSC value) UTRAN neighbour info
QSC: defines when the monitoring of UMTS cells will be performed (Active mode threshold Qsearch_C) QSCI: defines the control of UTRAN measurement after entering active mode (Active mode threshold initial (Qsearch_C_Initial))
UMTS to GSM
Strategy : HO when WCDMA when very bad radio conditions
Ericsson Default Parameters serve TT Strategy For Ericsson 2g BSS: RLSUP:CELL=ALL; This command prints system information UTRAN data for all internal cells in the BSC.
