Overview
2G-3G-LTE Priority based cell reselection is needed when user with multi-RAT capable MS (MS classmark3) roam between successive layers of LTE, WCDMA and GSM radio networks without loss of service and
camp on the available RAT with most priority.
Priority cell reselection works on having priority for different frequencies, the priority can be higher or
lower priority than the GSM.
MS shall search for and monitor higher priority frequencies regardless of signal strength in the serving
GSM cell. MS shall perform measurements of lower priority frequencies when RLA_C (Receive Level
Average) of the serving GSM cell is below the threshold set by MEASTHR.
Up to 64 UTRAN cells related to up to 32 UTRAN frequencies may be defined for cell reselection
measurements in idle and packet transfer mode. Up to 8 LTE frequencies may be defined for active mode
measurements. For each LTE frequency defined, one less GSM cell may be defined for active mode
measurements.
Need Early Classmark sending to assure that the system knows about the UTRAN FDD capabilities
(setting of parameter ECSC =YES).
Need to check BSC Licenses, which are allocated and calculated on timeslot basis.

Cell reselection to LTE (CRESLTE) and FAST Return to LTE after Call Release
(FASTRETURNLTE) are BSC AXEPARS parameters and should be activated and checked
with following command-
Also need to check BSC capacity licenses for these features like as follows-
