Information on subway information using mobile communication terminal {SUBWAY INFORMATION GUIDE METHOD USING MOBILE COMMUNICTION TERMINAL}

The present invention relates to a method of guiding subway information using a mobile communication terminal, and more particularly, to a method of guiding subway information using a mobile communication terminal for guiding a shortest route and a required time to a departure point and a destination during a movement.

Recently, in Seoul and other large cities nationwide, the traffic sharing rate of subways has increased due to heavy traffic jams. It is expected.

In this situation, as the opening of the subway increases, the routes become more complex, so if the destination is new or unfamiliar, you can move quickly to your destination if you do not have a route map or use the subway route guidance system installed in the subway station premises. There will be no.

In general, the subway line guidance system as described above is a system in which a user inputs a subway station to depart and a subway station to arrive, and displays the contents desired by the user such as the shortest route to the destination. Because it is installed only in the exhibition, there is an exhibition effect, but it is not very effective for users compared to its installation cost.

In addition, because the rapid upgrade of the system contents according to the expanded subway line is not made, there is a problem that the user does not provide exactly the desired information.

Recently, some internet service companies have provided subway-related information. In this system, if a user enters a departure station and an arrival station, information is provided from a server operated by the service provider. It does not provide.

As described above, in the conventional subway route guidance system, there are not many installation places, and it is difficult to upgrade the contents of the system, and mainly because the Internet service is available only in a wired network environment, when walking or moving from the outside. There is a problem that is not available.

Therefore, the present invention has been created to solve the above-mentioned problems, and when subway information is needed, it is possible to conveniently search for subway information using a mobile communication terminal regardless of time and place, and the destination. An object of the present invention is to provide a subway information guide method using a mobile communication terminal so as to grasp the optimal route and time required.

5 is an exemplary view illustrating a process of using a subway line information service using a mobile communication terminal.

Figure 6 is a flow chart shown to explain the subway information guide method according to the present invention.

In order to achieve the above object, the present invention provides a mobile communication terminal having a wireless Internet access, comprising: a first step of selecting a corresponding service menu by using a keypad provided in a main body of a terminal to obtain desired subway information; Determining whether the selected subway information is searchable by the terminal itself; A third step of directly searching for information searchable by the terminal itself and outputting the result; As a result of the determination of the second step, if the direct search is not possible, the fourth step of accessing the service provider's homepage, searching for related information, and outputting the result is performed.

Hereinafter, an embodiment according to the present invention will be described in detail with reference to the accompanying drawings.

The present invention, as shown in Figure 1 is equipped with a subway guide program in the form of a user interface program inside the mobile communication terminal to directly search for subway information, or as shown in Figure 2 subway information service service provider via wireless Internet The subway information is downloaded and displayed from the server.

First, a method of directly searching by installing a subway guide program inside a mobile communication terminal, when the subway information is upgraded, receives the contents from the base station and stores the contents in the mobile communication terminal, so that even in an area where transmission and reception with the base station are not made later, Allows you to search for subway line information.

Next, a method of retrieving subway information using the wireless Internet allows a mobile communication terminal to receive a desired information by accessing a server of a service provider providing a subway information service through the Internet. Lets you search for the subway information you want

At this time, the server of the subway information providing service provider mounted on the mobile communication terminal providing information through the subway route guidance program or the wireless Internet should consider the following points in order to select the shortest route.

1) Calculate the time required at each station between the departure and arrival stations.

2) The user's convenience is improved by minimizing the possible transfer section.

In general, a search theory using a tree structure is mainly used to find the shortest path considering the above matters.

For example, if there is a subway line in Seoul, as shown in Figure 3, when designating the departure station as the city hall and the arrival station as Seolleung, as shown in FIG. Three paths can be selected.

Among them, the priority to consider in selecting the shortest route is the number of stops, whether it is a transfer, the time required for the transfer, and the time required between stations.There are 19 stops on Route 1 and 24 stops on Route 2. If the number of stop stations of route 3 is 15, setting the shortest route only by the number of stop stations will cause an error that route 3 is set.

However, when considering the time required for the movement between stations on each route, route 3 has two transfer stations and at least five minutes of transfer time at each transfer station, It turns out to be the shortest path.

In this case, each of the above paths should be considered with the user's convenience as the priority, and the candidate group is extracted by comparing the value of A first with the transfer status and the number of transfer stations [A] prior to the total number of stations [B]. This allows you to choose a route that minimizes the number of stations.

Next, a process for using the subway line information service using an actual mobile communication terminal will be described with reference to the exemplary diagram of FIG. 5 and the flowchart of FIG. 6.

First, when the user presses a menu key button on the screen of the mobile communication terminal as shown in FIG. 5A, a list of various services provided by the mobile communication terminal is displayed as shown in FIG. 5B.

Accordingly, when the "Subway Information Service" menu is selected, various submenus thereof are output. When the "Subway Route Search" menu is selected, a message asking for the departure station is displayed as shown in FIG. 5 (c). After entering the departure station and pressing the Select button, a message asking for the arrival station is displayed as shown in (d) of FIG. 5, and entering the arrival station here and pressing the Select button, from the departure station to the arrival station by the shortest route selection method as described above. The shortest path is retrieved.

In other words, if the departure station is Gyeongbokgung and the arrival station is Jamsil, there are four paths to choose from.

Route 1: Gyeongbokgung Palace (Line 3) → Euljiro 3-ga (Transfer Line 2) → Arrival at Jamsil [Transfer Station: 1] [Stop Station: 16]

Route 2: Gyeongbokgung Palace (Line 3) → Shift (Transfer Line 2) → Arrival at Jamsil [Transfer Station: 1] [Stop Station: 20]

Route 3: Gyeongbokgung Palace (Line 3) → Jongno 3-ga (Transfer Line 1) → Sinseol-dong (Transfer) → Seongsu (Transfer Line 2) → Arrival at Jamsil [Transfer Station: 2] [Stop Station: 12]

Route 4: Gyeongbokgung Palace (Line 3) → Jongno 3-ga (Transfer Line 5) → Wangsimni (Transfer Line 2) → Arrival at Jamsil [Transfer Station: 2] [Stop: 16]

In addition, considering the time required between the transfer station and each stop, Route 3 has four fewer stops than Route 1, but considering the convenience of people actually moving, Route 1 is found to be the optimal shortest route.

When the route 1 is selected as described above, all the stop stations of the route 1 are displayed on the screen, and if the geographic information system is combined, the display of the current stop station and a message to transfer at each transfer station may be output.

In this case, the information retrieval service as described above may be directly performed without transmitting and receiving with the base station while the relevant information is mounted on the terminal itself, or may be performed by accessing a homepage providing the information.

If the information directly searchable by the terminal itself is downloaded and upgraded at a predetermined period, the upgrade may be performed by the service provider, or if necessary, the service provider may automatically upgrade the upgraded information through the base station.

Next, when the subway information service is provided through the wireless Internet, the information service is provided in the same process as above except that the process of accessing the subway information service server is further included.

In addition, it is easy to add and delete services simply by modifying the website of the subway information service provider, and thus, it is possible not only to obtain subway boarding time but also to efficiently use the subway through the dispatch interval of the subway train information system. .

For example, a user may access a subway information service menu of a mobile communication service provider's homepage to search for a subway operation time at a specific station, or search for a location of a subway chuck nearest to his current location using a location tracking menu.

In general, location tracking can be easily determined by using triangulation using three base stations.

As described above, the subway information guidance method using the mobile communication terminal of the present invention can always use the subway conveniently by using the mobile communication terminal regardless of time and place when necessary, and the optimum route and required route to the destination. Since the time can be grasped, it is effective for the traveler or the first-time passenger to be guided to the destination quickly and without trial and error.

In addition, the subway information can be upgraded quickly and the subway information of all regions can be provided in a consistent manner, thereby enabling the user to search for the information in a familiar manner.

In addition, when linked with a location tracking system using a satellite or a base station, there is an effect that can be developed into a comprehensive integrated traffic information guide system linking the ground transportation and the subway than when moving from one area to another.
