However, in the first embodiment of the present invention, the mobile terminal 20 includes a stop signal receiver 28 capable of receiving a stop identification code transmitted from the stop signal transmitter 10, and the storage unit 27. Is characterized in that it includes a destination DB which maps and stores the names of all stops and their identification codes.

In this case, the stop signal receiver 28 may be manufactured integrally with the RF module 22 for mobile communication.

In addition, the data of the destination DB is received and updated periodically or at the request of the user from the destination DB server 40.

In addition, the mobile terminal 20 has to compare the received stop identification code and the set destination information to determine whether the destination has arrived, and should be equipped with an application that notifies the user in a set manner when determined to arrive.

Hereinafter, a destination arrival notification service according to a first embodiment of the present invention will be described with reference to the flowchart of FIG. 2 and FIG. 1.

First, in the mobile terminal 20, a destination DB for storing identification codes of all stops is constructed, and an application for determining whether the destination arrives and notifying the user in a set manner according to the determination result is mounted. (ST11)

Subsequently, a user who uses a bus or subway sets a destination on the mobile terminal 20. 3 is a diagram illustrating a procedure of selecting a destination bus stop on a DMB terminal, for example.

First, if "Yes" is selected in the DMB reception selection menu, "Yes", a destination input screen is displayed, and if a character "Yeoksam" is entered on the input screen, a selection menu for starting a specific bus stop is displayed.

When the user selects a destination stop (eg, Yeoksam station) from the selection menu, the information of the selected destination stop is stored in the mobile terminal 20, and then the DMB broadcast is displayed so that the user can watch. (ST12)

Whenever the bus on which the user boards approaches the bus stop, the bus terminal receives the stop identification code sent from the stop signal transmitter 10, and the control unit 21 of the mobile terminal 20 identifies the received stop according to the algorithm of the application. The code is compared with the identification code of the destination set by the user to determine whether there is a match. (ST13, ST14)

If the result of the determination does not match, the next decision process is performed again at the next stop. If it is determined to match, the user must be notified of the arrival of the destination according to the set method.

Although the notification method is not particularly limited, when watching TV broadcasts through the DMB terminal, for example, as shown in FIG. 4, the subtitle "Now, I will arrive at the destination Yeoksam station" will be displayed. It is preferable to output audio.

If you are listening to a radio broadcast through a DMB terminal or listening to music through an MP3 player or MP3 phone, it is preferable to output the audio. It may also generate vibrations with (or instead of) subtitles or voice. (ST15)

Second embodiment

For the first embodiment of the present invention, as shown in FIG. 1, a stop signal transmitter 10 is installed at each stop, and the mobile terminal 20 receives a stop identification code transmitted from the stop signal transmitter 10. A stop signal receiver 28 should be provided.

Therefore, in order to apply the first embodiment of the present invention, a stop signal transmitter 10 must be installed at each stop, and a stop signal receiver 28 must be installed in the mobile terminal 20.

Accordingly, the second embodiment of the present invention provides a method of informing a user of destination arrival information by using a PN (Pseudo Noise) signal periodically transmitted from an existing mobile communication base station.

The PN signal is a base station identification signal continuously transmitted from a base station that performs wireless communication with a mobile terminal. Since adjacent base stations transmit different PN signals, the base station PN signal is identified as an identification signal of an area or a destination in a city where the base stations are concentrated. Can be utilized as

Therefore, in order to use the destination arrival notification service according to the second embodiment of the present invention, the mobile terminal 50 controls the overall operation of the mobile terminal 10 as shown in FIG. 60) and the RF module 52 for performing wireless communication, the audio output signal received from the RF module 52 through the speaker or the audio signal input through the microphone through the RF module 52 to the outside And a processing unit 53, an LCD module 54, and a storage unit 55 for storing a terminal operating program. The storage unit 55 maps a region name representing each base station to a PN signal of the base station. A destination DB to be stored must be provided.

In addition, it should be provided with a determination means for determining whether the destination arrives by using the received PN signal.

The second embodiment of the present invention provides not only mobile communication devices such as cellular phones and PCS phones, but also DMB-only receivers, MP3 players, PDAs (Personal Digital Associates), PMPs (Portable Multimedia Players), and the like, provided that the destination DB and determining means are provided. It may be included in the mobile terminal 20 according to the example.

Hereinafter, a destination arrival notification service according to a second embodiment of the present invention will be described with reference to the flowchart of FIG. 6 and FIG. 5.

First, a mobile terminal 50 constructs a destination DB for storing PN codes of all base stations, and determines whether the destination arrives and mounts an application for notifying the user in a set manner according to the determination result. (ST21)

Then, a user using a bus or subway sets a destination on the mobile terminal 50. Since the setting method is the same as the method described with reference to FIG. 3, the description is omitted here. (ST22)

Since the mobile terminal 50 continuously receives the base station PN signal from the neighboring base station, once the destination arrival notification service is set in the mobile terminal 50, the mobile terminal 50 is a base station mapped to the received base station PN signal and the set destination. It periodically determines whether the PN codes match.

This confirmation process continues even when the bus or subway on which the user is boarded moves. (ST23, ST24)

If the result of the determination does not match, the above-described determination procedure is repeated. If it is determined to match, the user should be notified of the arrival of the destination according to the set method. Since the notification method is the same as that described in connection with the first embodiment, the description is omitted here. (ST15)

According to the present invention, since there is no need to access a separate location information providing server, an increase in communication traffic can be avoided from the user's point of view, and the user can easily and inexpensively arrive at the destination based on the destination DB stored on the mobile terminal. Notification service will be available.
