if you want to sharing traffic to reduce blocking, you can use idle and dedicated parameter,
for idle parameter u can use CRO & RvLevAccessMin
for Dedicted Parameter u can use Inter-cell HO Hysteresis if same layer, PBGT if want to share GSM to DCS, interlayer HO threshold& Hysteresys if different layer (up layer), Min UP / DL Power on HO Candidate Cell (for incoming), Edge HO UL / DL RX_LEV Threshold (for outgoing)..
i think that's enough.. for detail's please see BSS Help system :victory:
