During a handover decision, if this parameter is set to Preference for 2G Cell, the BSC first selects the target handover cell from the 2G candidate cells; If this parameter is set to Preference for 3G Cell, the BSC first selects the target handover cell from the 3G candidate cells; If this parameter is set to Preference for 2G Cell By Threshold, and if the receive level of the first candidate cell among 2G candidate cells is lower than or equal to HO Preference Threshold for 2G Cell, the 3G cell handover is preferred. Otherwise, the 2G cell handover is preferred. |
