Receive railway station information (e.g., exit-specific peripheral information, route / distance / time required from exit to a specific point, etc.) from the data radio channel (DARC) on the basis of this railway station information to the user from the current location to the destination. It provides a destination information providing method using the railway station information received by the mobile communication terminal to the DARC.

In the present invention, the railroad vehicle refers to a vehicle that transports people and cargo on a railroad, such as a train, a train, an electric car, a subway road, and a high speed rail. Hereinafter, the present invention will be described by taking a specific station (hereinafter referred to as "underground railway station") of the subway.

In general, when people want to go to a specific place, they get on public transportation such as subway roads, get off at subway stations near their destinations, and then move to exits corresponding to the destination directions. Here, after getting off at the subway station, if the stranger area, that is, do not know the destination information, people visually check the signboards, milestones, etc. installed in the subway station, then recognizes the destination direction and moves to the corresponding area.

However, there is a problem in that it is not possible to properly provide the destination information to people through an electronic signage or a milestone installed in a subway station. In other words, billboards, milestones, etc. provide the public with only the usual geographic information around the metro station (e.g., store A is located in the exit direction), and each individual heading to a different destination from the metro station to its destination. Can't provide accurate information such as route / distance / time required.

Meanwhile, a location based service (LBS) technology and a geographic information system (GIS) recently associated with a global positioning system (GPS) technology. Geographical Information System (hereinafter referred to as "GIS") With the development of technology, it is possible to be informed of the location, surrounding information and route of movement of people or objects at anytime and anywhere.

However, in order to receive the surrounding information / movement path guide as described above, the user must have a terminal equipped with a GPS function, and furthermore, the user must subscribe to a destination information service through a mobile communication service provider. The burden is on the cost and service fee.

Therefore, when a user who does not have an expensive GPS terminal or a user who does not subscribe to a paid destination information service is located at a subway station near the destination, he / she can determine the route / distance / time required from the subway station to the destination. There is an urgent need for a technology that allows a user to properly recognize a mobile terminal and move to a destination quickly.

The present invention has been proposed to solve the above problems and to meet the above demands, and provides railway station information (eg, peripheral information for each exit) from a data providing apparatus installed at a railway station in a mobile communication terminal to a data radio channel (DARC). Information about the route / distance / time required from the exit to a specific point) and provides the user with information from the current location to the destination based on the railway station information. The purpose is to provide a method for providing destination information.

It is implemented as a low-cost device equipped only with the ability to transmit local information to a limited area by radio wave.

On the other hand, in order to explain the function of the information providing apparatus, the components corresponding to the respective functions are expressed in blocks, but it is preferable that the above-described functions are implemented as a single FM transmitter. Therefore, it will be readily understood by those skilled in the art that not only is it expensive to construct such an information providing apparatus in a number of subway stations, but also that it is easy to construct the information providing apparatus.

On the other hand, the mobile communication terminal 10 is preferably equipped with a radio broadcast reception function, in particular DARC reception function. Here, it will be readily understood by those skilled in the art that the DARC reception function may be implemented as a low cost device, and in particular, much cheaper than a device for implementing a GPS function. In addition, receiving the information in the DARC, which is a public channel, in the mobile communication terminal 10, there is no service fee, and anyone can use the corresponding frequency channel.

That is, the mobile communication terminal 10 includes an FM antenna, an FM tuner, an FM demodulator, a DARC demodulator (aka LMSK demodulator), a DARC decoder, a speaker, a display unit, a controller, and the like. Here, it will be readily understood by those skilled in the art that the component for the radio reception function, that is, the FM demodulator, is an additional component.

In addition, the mobile communication terminal 10 is preferably equipped with a program for calculating destination information based on geographical information (ie, railway station information) and user input information acquired from the outside in order to provide destination information to the user. In addition, although the present invention will be described using the mobile communication terminal 10 as an example, any terminal (eg, PDA, notebook, etc.) equipped with a DARC receiving function and an information display / output function may be used.

Hereinafter, each component of the information providing apparatus installed in the subway station A will be described in detail.

The information providing server 20 generates railway station information (eg, peripheral information for each exit, a route / distance / time required from an exit to a specific point, etc.), and the FM transmission center 30 is an information providing server 20. The railroad station information generated by is converted into information of a format suitable for DARC (hereinafter referred to as "railroad station information for DARC") to be transmitted to the subway station A through the FM transmitter 40. Accordingly, the mobile communication terminal 10 located in the subway station A receives the railway station information through the DARC.

The information providing server 20 generates railway station information (for example, peripheral information for each exit, route / distance / time required from an exit to a specific point, etc.) based on data input by an administrator or the like, or a management device when connected to the Internet. It can also receive and update the information in real time. In addition, the information providing server 20 has not only railway station information but also other useful information such as station introduction information, waypoint information, transfer information, travel time between other stations, introduction of nearby shops, surrounding tour guide, news, weather, and linked bus guide. And other such information may be provided to the mobile terminal user.

The FM transmission center 30 converts the railway station information forwarded (delivered) from the information providing server 20 to the railway station information for DARC, and then FM through the FM transmitter 40 according to the data radio channel (DARC) transmission protocol. DARC railway station information is loaded in the spare band of the frequency band and transmitted to the metropolitan station A through the data radio channel.

On the other hand, when the user is located in the metropolitan station A, it is preferable to let the user know the railway station information providing channel for DARC so as to obtain the railway station information through the mobile communication terminal 10.

For example, the information on the number of channels provided for DARC railway station information is displayed on the entrance billboard of the subway station A, the billboard inside the subway, and the user adjusts the DARC receiving channel of the mobile communication terminal 10 to the railway station through the corresponding channel. The information is provided so that destination information can be obtained.

2 is a flowchart illustrating a method for providing destination information using railway station information received by DARC in a mobile communication terminal according to the present invention.

The metropolitan station A is provided with an information providing apparatus, that is, an information providing server 20, an FM transmission center 30 and an FM transmitter 40, and the information providing apparatus is previously stored or newly updated information, preferably Railway station information (e.g., exit-specific ambient information, route / distance / time required, etc.) Station introduction information, waypoint information, transfer information, travel time between other stations, introduction of nearby shops, tour information around, news, weather, guided bus information, etc.] are continuously sent to subway station A at regular intervals. In this case, the information, such as news, weather, etc. is preferably updated in real time and sent as the latest information, other information, for example, the exit / exit time and the route / distance required time to a specific point around due to the exit closure Even if this is changed, it is desirable to update and send the latest information.

Referring to the transmission of the railway station information from the information providing device installed in the metropolitan station A as described above and providing the destination information to the user based on the railway station information in the mobile communication terminal as follows.

First, the information providing server 20 generates railway station information (eg, peripheral information for each exit, a route / distance / time required from an exit to a specific point, etc.) (200). Here, the exit-specific surrounding information includes point of interest (POI) information such as a specific shop / public office / building around a railway station, for example, location information of a specific point such as a building name, a building address, a building location on a map, and the like. The information providing server 20 then forwards the generated railway station information to the FM transmission center 30.

Thereafter, the FM transmission center 30 converts the forwarded railway station information into information (hereinafter, referred to as "DARC railway station information") in a format suitable for a data radio channel (hereinafter referred to as "DARC"). At this time, the FM transmission center 30 inserts the railway station information into the data area of the frame according to the data radio channel (DARC) transmission protocol and converts the railway station information into the railway station information for the DARC.

Then, the FM transmission center 30 continuously transmits the DARC railway station information to the subway station A through the FM transmitter 40 (202). At this time, the FM transmission center 30 encodes the DARC railway station information into an analog frequency signal in the FM frequency band according to a known data radio channel (DARC) transmission protocol, and the FM station of the DARC railway station information in the form of the encoded analog signal is FM. After high frequency conversion, FM modulation is performed to load the railway station information for DARC in a spare band of the FM frequency bands, and to transmit it to the outside, that is, subway station A through the FM transmitter 40.

In particular, the FM transmission center 30 controls the FM transmitter 40 so that the railway station information is not transmitted to the outside of the metropolitan station A, that is, the other metropolitan station and other DARC networks, and between the respective restricted areas. Railway station information provision for DARC The transmission output is controlled so that interference between channels does not occur, thereby limiting the railway station information transmission range for DARC (preferably in the range of 200 to 400 meters according to the radio wave management law). Thus, the mobile communication terminal user can be provided with the railway station information when located within a certain radius of the subway station A.

In addition, the FM frequency bands for the DARC railway station information transmission in each restricted area are preferably allocated from the radio wave management station or the like, but all the restricted areas may use the same FM frequency band. In other words, due to the substantially limited number of channels, it is difficult to allocate different FM frequency bands to all of the restricted areas, and as described above, the mobile communication terminal located in the restricted area of the DARC railway station information by controlling the FM transmission output. It is possible to communicate only to (10), so that each restricted area can use the same FM frequency band.

Meanwhile, it is preferable that a periodic redundancy check (CRC) area for a data transmission error check is added to the DARC railway station information carried on the FM frequency band.

Subsequently, when the user who boards a subway car gets off at subway station A or passes through subway station A (that is, when the user is located in subway station A), the mobile communication terminal 10 of the user performs DARC reception function. Receives and stores the railway station information for DARC through (203). Here, it is preferable that the mobile communication terminal 10 is notified in advance of the FM frequency band, that is, the DARC railway station information providing channel (frequency band), from the subway station A side (railroad management station, etc.) in advance. It is desirable to set the channel of the DARC railway station information providing channel and wait for the DARC railway station information to be received. In addition, the mobile communication terminal 10 may detect a data error and correct the error through the CRC area information added to the received DARC railway station information.

Thereafter, the mobile communication terminal 10 notifies the user that the railway station information on the surrounding geography of the subway station A has been received, and then requests the user to decide whether to receive the destination information by displaying / outputting the railway station information (204). ).

Then, the mobile communication terminal 10 selects a destination to go from railway station information according to the user's destination information providing program driving, menu selection, etc. (when the user decides to receive the destination information provision). Ask the user for input to specify the current location (205). Accordingly, the user selects the corresponding destination, the current location, and the like into the mobile communication terminal 10.

Then, the mobile communication terminal 10 inputs the user's input information (e.g., destination selection, current location designation) and railway station information (e.g., peripheral information for each exit, route / distance / time required from the exit to a specific point). Based on the calculation, the destination information (for example, a path / distance / time required from the current location to the destination) is calculated and displayed on the screen or output to the speaker (206).

On the other hand, other information [eg; Station introduction information, waypoint information, transfer information, travel time between other stations, introduction of nearby shops, nearby tour guides, news, weather, linked bus guides, etc.] are received by DARC. Can be obtained.
