The location trigger system according to claim 5, wherein the plurality of communication apparatuses comprise a Mobile Positioning Center (MPC), a Home Location Resister (HLR)/Mobile Switching Center (MSC)/Visitor Location Resister (VLR), and a Position Determination Entity (PDE). 7. The location trigger system according to claim 1, wherein the LA and the LBSA co-exist with the MS on a network, or are separately provided thereon. 8. The location trigger system according to claim 1, further comprising a location server installed on the LP, the location server obtaining the location trigger and a simplified location of the MS. 9. The location trigger system according to claim 8, wherein the location server comprises: a location trigger access application for accessing a location trigger inputted from a location agent or a trigger operator tool through the LP; a location trigger analyzer analyzing the location trigger, and dividing a complex location trigger into a multi-level location trigger; a trigger processor directly accessing a terminal to invoke a trigger, and detecting associated events; a location trigger event processor monitoring the events provided from the trigger processor, comparing the events to a location trigger DB, and detecting an associated trigger; and an executor executing the triggered events. 10. The location trigger system according to claim 9, wherein the trigger processor comprises a simple location trigger (LT) processor, a time trigger LT processor, an MS-Assisted LT processor, and an MS-Based LT processor. 11. A location trigger method for a Location-Based Service (LBS), comprising: (a) a location agent (LA) setting a location trigger; (b) an LBS platform (LP) transmitting initial information of the location trigger to a mobile station (MS); (c) the MS in which the LA is embedded detecting a location trigger event, the MS detecting the location trigger event by comparing a location identifier of the MS with a list of location identifiers of interest; (d) the MS transmitting information of the location trigger event to the LP, the location trigger event invoked based on the location trigger; and (e) the LP processing the location trigger according to the information of the location trigger event. 12. The location trigger method according to claim 11, further comprising providing an LBS application with a location-based service in accordance with the location trigger processed by the LP. 13. The location trigger method according to claim 11, wherein in b), the LP searches through a Cell-ID Area DB and transmits an associated Cell-ID to the MS. 14. The location trigger method according to claim 11, further comprising obtaining a radio signal including the MS Cell-ID, the repeater ID, the service antenna ID, the MAC address of a wireless LAN, and a Bluetooth ID, and invoking the location trigger event using a device covering a relatively smaller area when another device covering a relatively bigger area satisfactorily processes a trigger event. 15. The location trigger method according to claim 14, further comprising: setting the location trigger for a particular building or area within a particular cell; detecting whether the MS enters the particular cell through a Cell-ID level location trigger using the LAT embedded in the MS; and detecting a more precise location trigger by turning on an Assisted-GPS when the MS enters the particular cell. 16. The location trigger method according to claim 11, wherein the LAT and the LP use a plurality of messages to process the location trigger. 17. The location trigger method according to claim 16, wherein the plurality of messages comprise an LT setting message (LT-SET), an LT initialization message (LT_INIT), an LT event message (LT_EVENT), and an LT action message (LT_ACTION). 18. The location trigger method according to claim 11, wherein the LAT detects a simple event related to entering/exiting of the MS, and the LP performs a complex event, independently performing associated actions. 19. The location trigger method according to claim 11, wherein the MS is an MS-based terminal capable of independent performance of the complex event and the associated actions. 20.
