1. A Digital Multimedia Broadcasting (DMB) terminal for providing a DMB service, wherein the DMB terminal performs a method comprising the steps of:
- monitoring the occurrence of a channel search request;
identifying a current location of the DMB terminal;
searching a connection channel as a transition relation corresponding to a channel received in a previous service area when the DMB terminal moves from the previous service area to another service area;
searching a channel service area database, which includes channel service area information according to areas, for the another service area corresponding to the current location; and

Abstract
A method, apparatus and system for Digital Multimedia Broadcasting (DMB) service are provided. A DMB receiving terminal identifies a channel service area in which the DMB receiving terminal is currently located based on an identified current location, and configures a channel information list by searching only a frequency band corresponding to the channel service area. When the channel service area is changed, the DMB receiving terminal searches a pre-stored connection channel list, and identifies a predetermined channel established as a transition channel corresponding to a channel which the DMB receiving terminal has received, from channels belonging to the changed channel service area. The DMB receiving terminal then receives the identified channel and provides terrestrial DMB service, thereby reducing a channel search time period and smoothly providing the terrestrial DMB service.
