Dmb handover method and dmb handover system for scanning first of all adjacent region

A DMB handover method and a system thereof are provided to enable a user to quickly and conveniently confirm the current region on a DMB terminal by inserting information for discriminating regions into a DMB signal. A DMB handover method comprises the following steps of: storing a table in a DMB terminal(110); monitoring the receipt quality of DMB signals provided to the DMB terminal(120); determining whether the strength of the current DMB signal is identical or less to or than a critical value(130); confirming a neighboring region by referring to the table stored in the DMB terminal(140); preferentially scanning a frequency corresponding to the neighboring region to process the handover of the DMB terminal(150).
