 Ø  Contains information relevant only for inter-RAT (GERAN) cell re-selection


Information’s:
t_ReselectionGERAN
Time to trigger for reselection. Value 0 to 7 sec.
carrierFreqsInfoList[0]
carries upto 16 instances of GERAN freq.
carrierFreqs

startingARFCN
Start of the ARFCN
bandIndicator
dcs1800 or pcs1900
followingARFCNs
ARFCN groups
cellReselectionPriority
Absolute priority of the GERAN layer. Value 0 to 7, whereas 0 is the lowest priority
ncc_Permitted
Network Color Code. Is a bitmap value
q_RxLevMin
minimum RSSI value required
p_MaxGERAN
maximum allowed UL transmit power
threshX_High
# Threshold (in dB) used by UE for cell re-selection to a HIGHER priority frequency
#  The Srxlev of the candidate cell is greater than threshX_High
# Value 0 to 31 dB. Actual value= Signaled value * 2
threshX_Low
# Threshold (in dB) used by UE for cell re-selection to a LOWER priority frequency
#  Cell re-selection is allowed only when Srxlev of the candidate cell is greater than threshX_Low and RSRP of serving cell is less than the value of ThreshServingLow singalled within SIB3
# Value 0 to 31 dB. Actual value= Signaled value * 2
