A novel mobile station for a CDMA system does not repeat initial pilot acquisition, when a call is abnormally released. The mobile station performs energy measurement on PN offset values of the neighbor base stations, received from the previous service base station, to determine a reference active sector. Based on whether the determined sector is identical to the previous reference active sector, call re-origination is performed from the sync channel state or the paging channel state. Accordingly, the user shouldn't have to redial and wait for a long time until the call re-origination is performed successfully. In addition, the mobile station does not need to perform initial pilot acquisition unnecessarily, and can reduce the time required for recovering the dropped call.
