csFallbackPrio
If there are several cells which can csfb to, we should define the csFallbackPrio
to decide which cell to csfb
set system constant cmccFtEnabled (332) to 1
set system constant cmccFtGeranDtmSupport (480) to 0
doesn’t support DTM

4.3 RIM
rimAssociationRetryTimer:
This parameter contains the time in minutes until the eNB will retry setting up the
association. The value -1 means that the timer is inactive.
rimAssociationRetryValue:
This parameter holds the value for the next time-out value.
that there is no set Retry Value.
The value -1 means
rimSIUpdateTimeOut:
This parameter holds the time in minutes until the next SI needs to have arrived.
If an update has not arrived when this value reaches 0 the eNB will assume there
are some problems with the RIM transmission and try to restart the association.
The value -1 means that there is no time out.
