초록
A method for performing a handover based on a compressed mode and a common frequency of neighbor cells is disclosed. The method for performing a handover includes the steps of: a) measuring the signal intensities of a common frequency of a source base station and a target base station, wherein the signal intensity is measured by the mobile station based on a downlink compressed mode; b) determining whether a handover is necessary or not, based on the signal intensities of the common frequency; c) if the handover is necessary, at the source base station, allowing the mobile station to perform intra cell hard handover from a frequency used for communication between the mobile station and the source base station to the common frequency; and then d) allowing the mobile station to perform a soft handover from the source base station to the target base station based on the common frequency.
