Description

[0001] MOBILE TERMINAL AND ROAD SEARCHING METHOD THEREOF [0002]

The present invention relates to a mobile terminal providing a shortest path to a destination in consideration of a scheduled arrival time of a transportation means, and a method of finding a destination.

The mobile terminal may be configured to perform various functions. Examples of such various functions include a data and voice communication function, a function of photographing a video or a moving image through a camera, a voice storage function, a music file playback function through a speaker system, and an image or video display function. Some mobile terminals include additional functions to execute games, and some other mobile terminals are also implemented as multimedia devices. Moreover, recent mobile terminals can receive a broadcast or multicast signal to view a video or television program.

Further, efforts for supporting and increasing the functions of the mobile terminal continue. Such efforts include not only changes and improvements in structural components that form the mobile terminal, but also improvements in software or hardware. Among them, the touch function of the mobile terminal allows a user who is unfamiliar with the button / key input to conveniently perform the operation of the terminal by using the touch screen. In recent years, not only simple input but also user interface (UI) Is becoming an important function of Accordingly, as the touch function is applied to a mobile terminal in various forms, development of a user interface (UI) corresponding thereto is further demanded.

In response to the development of communication technology and various needs of the user, various navigation functions are provided not only in mobile terminals but also in portals (Naver, Daum, etc.). Recently, .

If the user inputs the transportation means together with the departure place, the destination place, and the stopping route, the various route finding function derives the fastest route from the current location of the user to the destination (destination) and displays the route together with the map information.

However, the above-described conventional route search functions and applications merely display route and time information of specific transportation means (subway, bus, bicycle, walking, etc.) selected by the user, If the means exists, it does not provide comparative information on the means of transportation. That is, the conventional route search function provides the route search information based on the simple input information without considering the distance (walking time) from the current position to the station (or subway station) and the estimated arrival time of the transportation means .

However, for example, if the user is located at a point of 10 m to the bus stop and 50 m to the subway station at 3:00 pm, and assuming that the bus and subway intervals are 20 minutes and 5 minutes, respectively, Therefore, if a bus is selected as a means of transportation, the user may arrive at the destination later than the subway. The reason for this is that if you move at 3 o'clock and arrive at the bus stop at 3 o'clock, but the bus has already departed at 3 o'clock, you have to wait about 17 minutes to get on the bus arriving at 3:20, If the user arrives at the subway station at 3:9 am, the user will have to wait 1 minute and then ride the subway at 3:10. In this case, assuming that the time taken to get to the destination after getting on public transportation time is the same, the bus stop is closer than the subway station at the present location of the user, but the scheduled arrival time of the transportation means is different. You arrive at your destination about 10 minutes faster.

The conventional search function provided by the mobile terminal may use any means of transportation in consideration of the distance from the current location to the station (or subway station) (walking time) and the estimated arrival time of the transportation means, Does not provide comprehensive information on how long it takes to get to the transfer station and destination.

The terminal 100 shown in Fig. 1 is configured to be operable in a communication system capable of transmitting data through a frame or packet, including a wired / wireless communication system and a satellite-based communication system .

Hereinafter, a communication system capable of operating a terminal according to the present invention will be described with reference to FIG.

The communication system may use different air interfaces and / or physical layers. For example, wireless interfaces that can be used by communication systems include, but are not limited to, Frequency Division Multiple Access ('FDMA'), Time Division Multiple Access ('TDMA'), Code Division Multiple Access (CDMA), Universal Mobile Telecommunications Systems (UMTS) (especially Long Term Evolution (LTE)), Global System for Mobile Communications (GSM) . Hereinafter, for the sake of convenience of description, the description will be limited to CDMA. However, the present invention is applicable to all communication systems including CDMA wireless communication systems.

2, the CDMA wireless communication system includes a plurality of terminals 100, a plurality of base stations (BSs) 270, and base station controllers (BSCs) 275 , And a mobile switching center ('MSC') 280. MSC 280 is configured to be coupled to a Public Switched Telephone Network (" PSTN ") 290, and is also configured to be coupled to BSCs 275. BSCs 275 may be coupled in pairs with BS 270 through a backhaul line. The backhaul line may be provided according to at least one of E1 / T1, ATM, IP, PPP, Frame Relay, HDSL, ADSL or xDSL. Thus, a plurality of BSCs 275 may be included in the system shown in FIG.

Each BS 270 may comprise at least one sector, and each sector may comprise an omnidirectional antenna or an antenna pointing to a particular direction of radial from BS 270. [ In addition, each sector may include two or more antennas of various types.

FIG. 3 illustrates a movement path to which a method of searching for a mobile terminal according to the present invention is applied.

As shown in Fig. 3, at the current time 3 o'clock, the user tries to move to the destination (e.g., Guro Digital Complex) from the departure place (e.g. LG Gasan Digital Center). In this case, the user will not know whether it is fast to ride on the bus to Guro Digital Station (destination) or fast on the subway. Habitually use the subway or move to the nearest bus stop (in front of Yeongchang Unemployment). However, even if the user gets to the bus stop quickly, there is the inconvenience of waiting more than 30 minutes to get on the next bus if the bus time is not known or the accuracy is not correct.

Therefore, according to the present invention, when a user is located between at least one transportation means and travels to a destination by using the transportation means, the user can be informed of the current time, the traveling time to the transportation means, And suggests a way to tell the shortest time path.

4A and 4B are display screens of the shortest time path according to the embodiment of the present invention.

When the user selects the route search function from the menu, the control unit 180 displays the start and end destination input windows. When the user inputs the "LG Add-on Digital Center" and "Guro Digital Complex" (180) searches for the shortest time path from the origin to the destination for each transportation means based on the current time (3 o'clock), driving information provided in real time by the operation server of the transportation means, and GPS information.

4A is a search result for a subway, and FIG. 4B is a search result for a bus. Figs. 4A and 4B show the time comparison for each transportation means, but actually only the transportation means with the fastest estimated arrival time is finally selected and displayed on the screen.

As shown in FIG. 4A, when inputting the "LG Gas Digital Center" and the "Guro Digital Complex" respectively to the departure place and the destination (destination), the control unit 180 calculates the current time (3:00) (3:16 to 3:20) to the "Guro Digital Complex" based on the estimated arrival time of the subway (eg Line 7 and Line 2) along with the travel time (about 9 minutes) ).

4B, the control unit 180 determines whether or not a bus (for example, a bus) is connected to the bus stop (about 2 minutes) to the bus stop (about 2 minutes) based on the current time (3:00) (3:33 to 3:53) to the "Guro Digital Complex" based on the expected arrival time of the bus (bus No. 571, bus No. 5536).

The control unit 180 receives the scheduled arrival time (3:33 to 3:20) to the "Guro Digital Complex" by the subway and the scheduled arrival time (3:33 to 3:53) to the "Guro Digital Complex" And finally displays the shortest time path screen by the subway having a shorter expected arrival time as shown in FIG. 4A. At this time, when the user wants to view the shortest time path screen by the bus, the user can press the transportation mode switching button 50 displayed on the upper right side.

Therefore, the user moves to the destination (digital complex) while viewing the route information shown in FIG. 4A. When the user wants to view the detailed information while moving, the user selects the detailed route view, do. In this way, the distance from the departure point (LG Gasan Digital Center) to the subway station (Katsun Digital Station) is 4 times longer than the bus stop (in front of Yeongchang Univ.). However, since the intervals between buses and subways are different, Using the subway can go as fast as the Guro Digital Complex.

FIG. 5 shows an example in which a scheduled arrival time is recalculated and displayed when there is a transfer route while moving to a destination.

In FIGS. 4A and 4B, the estimated arrival time is a time calculated in consideration of the average travel time when the user rides the subway or travels the transfer route (the intermediate way point or the transfer station). However, unexpected accidents or breakdowns can cause delays in buses or subways, or traffic congestion. Especially in the case of subways, the estimated time of arrival at the destination varies during the time when many people are driving on the transfer station.

5, the present invention is provided with the "check station arrival" button 51 so that the arrival of the station arrival is determined based on the time when the corresponding button 51 is input The time (3; 45/4; 00/4; 20) and the estimated time of destination arrival (3:53 ~ 4.28) and the route are recalculated and displayed.

FIG. 5 shows an example of re-calculating the estimated arrival time when the bus is transferred to another bus and displaying the re-calculated arrival time. The same applies to the case where the subway is changed to another route. That is, even if the route from Line 7 to Line 2 is made, pressing the stop destination arrival confirmation button 51 recalculates the route and the estimated arrival time by comparing the arrival time of the transit station and the time of arrival of the subway and displays them on the screen. When the waypoint arrival confirmation is set at the time of inputting the route information at the beginning, the expected arrival time is automatically recalculated and updated.

On the other hand, when the user moves from the origin to the destination, not every user selects the shortest time path. The reason is that healthy users do not have a problem, but in the case of the elderly or those who have heavy burdens, they will choose a route that takes less time, but takes less time.

6A to 6C are display screens of a minimum walking route according to an embodiment of the present invention.

6A and 6B, when the user selects the "road distance item" together with the route search information (origin and destination) in the directions menu, the control unit 180 uses the subway and bus from the origin to the destination The estimated arrival time and the total walking distance of the subway are compared with the total walking distance to display a screen of the transportation means having a short total walking distance from the subway and the bus. For example, as shown in FIG. 6A, when the user moves from the LG Gasan Digital Center to the Guro Digital Complex using the subway, the total walking distance is 1050 meters. When the user moves from the LG Gasan Digital Center to the Guro Digital Complex Since the total walking distance is 377 m, the control unit 180 displays a display screen of the minimum walking route by the bus on the display unit 151.

Alternatively, the present invention can easily display the walking route display screen by pressing the walking distance display button 52 without selecting the road distance item from the route search menu. For example, when the walking distance display button 52 is provided on one side (right upper end) of the display screen of the shortest time path shown in FIG. 6A and the corresponding walking distance display button 52 is selected, And performs a search operation to display the display screen of the walking path as shown in FIG. 6B.

The present invention is not limited to this, and the present invention provides not only a road distance item but also other items desired by a user (for example, a less crowded route) in a route menu so that a user can select a travel route more variously.

6A and 6B, only the total walking distance is shown, but the present invention is not limited to this. As shown in FIG. 6C, the walking distance check button 53 for displaying the total walking distance, So that the walking distance for each individual walking segment can be selected and confirmed.

FIG. 7 is a flowchart illustrating a method of displaying a location information of a mobile terminal according to an embodiment of the present invention.

As shown in FIG. 7, when the user selects the padding function (menu) in the user menu, the display unit 151 displays an input window for searching for the memory 1600 and inputting the navigation information, The destination information includes basically a starting point and a destination, and additionally includes a shortest time, a shortest walking distance, and other items set by the user.

Once the location information is input, the controller 180 receives the location information of the user based on the current time when the user inputs the location information from the GPS receiver 115, (Bus, subway, train, and the like), receives the driving information for each transportation means from the server, and calculates the estimated arrival time to the destination for each transportation means (S12). At this time, each piece of information may be stored in the memory 160.

When the expected arrival time for each transportation means is calculated, the control unit 180 compares the expected arrival time for each transportation means (S13), selects the transportation means having the shortest expected arrival time (fastest) The time path screen is stored in the display unit 180 (S15). As shown in FIG. 4A, for example, the shortest time path screen may be a route from the current time (3:00) to the departure place (LG Gasan digital center), the distance from the departure place to the boarding place (Route 7), the transfer method, the transfer distance and time, the travel information (Line 2) of other routes at the time of transit, and the method of boarding, and finally the estimated arrival time to the destination (Guro Digital Complex).

When the user arrives at the destination (Guro Digital Complex) and terminates the route search function (S16), the controller 180 terminates the entire process. If the user searches for another region, the process returns to the step S11, Display the input window again.

When the user inputs the walking distance display button 52 in the state that the shortest time path screen is displayed, the control unit 180 displays the walking distance from the current location (LGGasan Digital Center) to the destination (Guro Digital Complex) It is possible to select the transportation means having the shortest walking distance after calculating the distance and display the display screen of the minimum walking route by the corresponding transportation means.

8 is a flowchart showing a processing method when an additional button is input in a state that the shortest time path screen is displayed.

As shown in FIG. 8, when the user inputs an additional button while the shortest time path screen is displayed, the controller 180 checks the type of the detected button (S20, S21). If it is determined that the corresponding button is the walking distance display button 52 (S22), the control unit 180 calculates the total walking distance from the current location (LGGasan Digital Center) to the destination (Guro Digital Complex) (S23). The control unit 1800 compares the calculated total walking distance by each of the transportation means (S24), selects a transportation means having the smallest total walking distance, and displays a display screen of the minimum walking route by the transportation means (S26).

As shown in FIG. 6A, the display screen of the minimum walking route includes a total walking distance at the lower end of the shortest time route screen 4a.

On the other hand, if the inputted additional button input is the stopover arrival confirmation button 51, the control unit 180 recalculates the estimated arrival time path based on the input time of the corresponding button as shown in FIG. 5, (S27, S28), and the displayed screen may be stored in the memory 160 for later use.

Therefore, the present invention can guide information for a user who does not want to walk in a state in which the shortest time path screen is displayed, and even when the time to the destination is changed due to an external situation (congestion, It is possible to display the expected arrival time, thereby providing convenience to the user.

In the present invention, the shapes and colors of the additional buttons are set to be different from each other.

As described above, according to the present invention, when there are a plurality of transportation means from the departure place to the destination place, the estimated arrival time is calculated for each transportation means to provide the minimum arrival scheduled time or the minimum walking distance screen, It is possible to arrive at the destination more quickly and conveniently than providing only the traffic information for the transportation means selected by the user.

Further, according to an embodiment of the present invention, the above-described method can be implemented as computer-readable code on a medium on which a program is recorded. The computer readable medium includes all kinds of recording devices in which data that can be read by a computer system is stored. Examples of the computer-readable medium include ROM, RAM, CD-ROM, magnetic tape, floppy disk, optical data storage, and the like, and also implemented in the form of a carrier wave (for example, transmission over the Internet) . Further, the computer may include a control unit of the terminal.
