The present invention discloses a method for accessing a cell, and more particularly, to a method for acquiring an initial synchronization using two pilot channels in a CDMA (Code Division Multiple Access) communication system of an asynchronous or quasi-synchronous mode. In accordance with the present invention, a CDMA communication system of an quasi-synchronous mode comprises the steps of synchronizing the mobile station with a cluster pilot, and searching for cell pilots on the basis of the cluster synchronization channel set up by the cluster pilot, and synchronizing the mobile station with the cell pilot having a maximum sensitivity, whereby the mobile station is synchronized with the base station through the cluster pilot and the cell pilot. Also, in accordance with the present invention, a CDMA communication system of a asynchronous mode comprises the steps of synchronizing the mobile station with a cluster pilot, and searching for all cell pilots in a cluster of which synchronization has been set up by the cluster pilot, and synchronizing the mobile station with the cell pilot having a maximum sensitivity, whereby the mobile station is synchronized with the base station through the cluster pilot and the cell pilot.
