<p>Disclosed is a method for performing roaming capable of minimizing a ping-pong phenomenon and a dual mode mobile terminal using the same. Functions for the method for performing roaming and the dual mode mobile terminal using the same are realized such that a ping-pong phenomenon occurring in a shadow area of one of the communication networks providing communication services using different mobile communication techniques can be minimized. To this end, it is determined if the dual mode mobile terminal is in a shadow area by counting the number of ping-pong occurrences in the process of performing a mode based on a corresponding communication service and a ping-pong period is adjusted only when the dual mode mobile terminal is in the shadow area, thereby minimizing a ping-pong phenomenon.</p> |
