Description

Location information management method and system {METHOD FOR MANAGING POSITION DATA AND SYSTEM THEREOF}

The present invention relates to a method for managing location information, and more particularly, by providing a standardized location information technology tool, allowing a location information provider to directly write location information, thereby securing more reliable location information, and using the communication network (Internet or It relates to a location information management method that can be provided to other users through a wireless communication network).

Various methods and techniques for providing location information and map information have been developed. Various location information providing technologies have been developed from simple map booklets to map information providing methods using GPS (Global Positioning System).

Atlases, which are still widely used, have a long renewal cycle of about one year, and do not accurately reflect the current geographic information because partial reorganization is carried out, rather than full reorganization. In addition, there are some restrictions in referring to this when necessary by having it in a vehicle or a house.

In addition, the atlas contains schematic geographic information due to the limitation of the scale, and it is not easy to know the exact location information based on this.

In order to overcome the limitations of these atlases, geographic information systems based on electronic maps are being built, and geographic information of such geographic information systems is available through the Internet or electronic map software.

Furthermore, a navigation system using a Global Positioning System (GPS) has been widely used.

However, even in the case of a solution based on such a geographic information system, the fundamental problems such as the map update cycle and the scale described above cannot be solved, and expensive portable terminals or navigation systems such as PDAs and notebook computers are not solved. You must have it in order to use geographic information.

In addition, there is a problem that cannot accurately express or display a specific point using only map information provided by such a geographic information system.

In the case of a map service provided in an Internet portal site, a search for a corresponding branch, a map of the branch is made, and a map can be sent to the other party by e-mail.

However, such a map has a problem of basically including a large number of data elements by clipping a part of the electronic map data without deformation, and also because of the large file size, there is no problem when exchanging these files on the web connected to a high-speed communication network. Sending these files by wireless communication to people on the go is not easy.

In addition, a mobile terminal such as a mobile phone has a small display window, which makes it extremely difficult to accurately display a target point in a large area, which is an obstacle to commercialization due to an inefficient aspect of poor visibility and discrimination.

The present invention has been created to solve the above-mentioned problems, by allowing the location information provider to directly write their own location information to ensure more accurate location information, and also by using the location information as the character path information and the map information. It is an object of the present invention to provide a location information management method for securing location information that can reduce the capacity of data and increase visibility.

The above has been described by separating the location information management server 130 according to the embodiment of the present invention into a module according to its function, but this separation is not a hardware separation but a simple functional separation, thereby limiting the scope of the present invention. Of course not.

The location information management server 130 is configured to perform the location information management method according to an embodiment of the present invention to be described below.

As shown in Figure 2, if there is a connection request (S201) from the terminal 300 connected through the communication network 200, the location information management server 130 authenticates the magnetic information of the user requesting the connection (S203).

The user's own information may be any information that can confirm whether the connection applicant and the registered user match. For example, it could be a username and password.

As a result of the authentication, if the magnetic information does not match, the process is terminated, and if the magnetic information matches, the connection is allowed (S205).

Then, the user selects any service item among the location information services provided by the location information management server 130 through the terminal 300 (S207).

The location information service preferably includes location information input service, previously stored location information modification service, previously stored location information search service, and location information transmission service.

The location information management server 130 determines what the location information service item selected from the user terminal 300 is through the communication network 200 (S211).

Hereinafter, description will be given for each type of selected location information service item.

First, when it is determined that the selected location information service is input of location information (S213), the location information management server 130 receives data on a target point to provide location information from the connected user terminal 300. The location information of the target point is set by exchanging signals with the user terminal 300.

More specifically, the location information management server 130 transmits the basic form for location information input through the communication network 200 (S221).

The basic form for inputting the location information is for receiving data on a target point, and as shown in FIG. 6, the location information input form preferably includes a mandatory entry 610 and an optional entry 620. Do.

Required fields 610 include business type, recall / trade name, telephone number, zip code, address, password data, optional input 620 is data for company name, company description, fax number, homepage, email address, etc. It is preferable to include. However, it is obvious that the required input items and the optional input items are not limited thereto.

The user inputs the required input items 610 and the optional input items 620 using his terminal 300 and transmits them through the communication network 200 (S223).

When the required input item is received, the location information management server 130 transmits a text path input form for setting the text path information for the target point (S225).

In the setting of the text path information, it is preferable to set the text path information reaching the target point using the means of transportation in a plurality of arrival processes for a predetermined type of transportation means.

For example, as illustrated in FIG. 7, location information may be set by a plurality of reaching processes for reaching the target point using a subway, a bus, and a passenger car.

More specifically, with respect to the predetermined means of transportation, the display of the means of transportation (710, 720, 730), the input unit display 740 for inputting the partial path text when using the means of transportation, the next partial path text input display A requestor display 750 requesting is displayed.

When text is input to the input device and the requestor is activated, an input device for inputting a next partial path text with respect to the set transportation means is displayed.

By repeatedly performing such a process, text path information including a plurality of reaching processes for reaching a target point for providing location information using a set transportation means is set.

FIG. 8 is a diagram illustrating a process of creating text path information including a plurality of reaching processes for reaching a target point by such a process.

After the user inputs the sequential arrival process on the input display 740, the user inputs the requester display 750 and repeats the process of inputting the next arrival process, thereby creating the character path information including the sequential arrival process. It becomes possible.

When the user writes the text path information on the target point as described above and transmits it (S227), the location information management server 130 receives it, sets the text path information on the target point (S229), and stores it. do.

Unlike conventional map data, by providing a path for reaching a target point as text information, when only text path information is transmitted, traffic during data transmission and reception can be greatly reduced.

In addition, the map simply displays the target point and its surroundings, whereas the text path can efficiently display the arrival process according to each means of transportation from the departure point to the target point.

In addition, by inputting a path by text, even in a portable terminal having a small display window, location information can be easily input, and location information can be easily searched. In addition, if there is an incorrectly input characters during input, only the partial path needs to be corrected.

Then, the location information management server 130 sets the direction information when there is a provision of the direction information from the user (S231 to S243).

Unlike the map data based on the conventional electronic map data, providing the attenuated map data makes it easier to determine the location, and greatly reduces the data volume, thereby greatly reducing the traffic during data transmission and reception. Therefore, by providing such a map information, it is possible to use the location information more effectively in a portable terminal such as a mobile phone.

First, the user transmits to the location information management server 130 whether the user inputs the map information about the target point to which the user wants to provide the location information through the terminal 300 (S231).

Then, the location information management server 130 determines whether or not to input the map information, if the request for entering the map information is terminated, and if the user requests to enter the map information, for the target point The map data is transmitted (S235).

Referring to FIG. 9, the map data includes identification information data 910 of a road and identification information data 920 of a building. The road identification information data is preferably identification information data for a center line of the road, and the building identification information preferably includes identification information about a building located near the target point.

At this time, by using the identification information as the structured data, it becomes easy to identify the deleted building / road of the user generated in the modification process, and as a result, there is less fear that an error occurs.

If the user requests modification of the transmitted map data (S237), the location information management server 130 modifies the transmitted map data in response to a request from the user terminal (S239).

Preferably, in step S239 of modifying the map data, deleting a part of the identification information of the road and / or building, inserting a direction indication arrow of a desired type in a desired position, and desired contents in a desired position. It may include inserting the text of the.

Since the data of the feature determined to be unnecessary from the preset map data can be removed, the readability of the map can be improved, and the amount of data required for the map can be greatly reduced.

The road and building identification data included in the map data can delete some of the road and / or building identification data that the user does not want to be displayed on the map, and can easily find the target point through the map. In order to display the desired direction of the direction arrow to the desired point, and to display the text 930 of the desired content at the desired position.

Since the shape and the display position of the arrow can be arbitrarily determined by the user, it is easy to select the arrow and the display position of a form suitable for the arrangement of the target point where the user resides and the feature around it. Therefore, various expressions are possible from the uniform electronic map image display.

In addition, by allowing the user to arbitrarily insert text, which is character information about the target point and its surroundings, the readability of the map can be improved, and the user can directly input text suitable for the specific situation.

The location information management server 130 sets the map information based on the modified map data (S241) and stores it (S243).

That is, the map information is set by deleting the data of the requested building or road, displaying the designated direction arrow at the designated position, and displaying the designated text at the designated position.

At this time, the display of the modified map information may be embodied in various forms. In other words, it can be embodied in various ways according to the process of generating the drug. For example, in the case where the directions are generated as a graphic image, the direction indication arrow may be displayed on the graphic, and the entire displayed image may be compressed and stored.

In this case, the map information may be stored in any form. For example, the graphic information based on the modified map data may be compressed and stored using a specific compression method (for example, GIF). As described above, even when compressed and stored as a graphic, since the graphic is created based on only a few pieces of information compared to the existing map data, the size is very small compared to the existing map data when compressed.

9 is a view showing an example of the map information set as described above. As shown in the figure, a simple and clear map of the target point is formed.

In addition, the user inputs whether the corresponding location information is not provided through his terminal (S245), and the location information management server 130 receives and stores the location information is not provided data (S247).

Unavailability data is data including information on whether to provide the location information to the public.

As described above, by directly receiving the text path information and the map information on the target point from the location information provider and database it, it is possible to construct the location information more effectively.

On the other hand, as shown in Figure 3, the location information management method according to an embodiment of the present invention, if there is a request for the correction of the preset location information from the user terminal 300 connected through the communication network 200, The method may further include location information modification steps S301 to S313 to correct the set location information.

After inputting the location information, even if the target site and the surrounding feature is changed, the user can modify the location information inputted accordingly accordingly, so that the user does not need to create the location information newly.

In step S211, when the selected service item is location information modification (S215), the location information modification requester inputs data on a modification target point through his terminal 300 (S301).

When the location information management server 130 receives the data on the corrected target point (S303), it is determined whether there is a right to modify the position information corresponding to the corrected target point (S305).

Whether there is a right to modify may be determined by whether the person who inputs the corresponding location information and the person who requests the correction are the same, for example, based on the ID and the password.

In step S305, if it is determined that there is a right to modify the corresponding position information, and transmits the preset position information for the corrected target point to the terminal of the correction requester (S307).

The terminal 300, which has received the preset location information on the modified target point, modifies the location information as desired by the user (S309).

The terminal 300 receives the modified position information (S311), and resets the position information on the corrected target point as the corrected contents (S313).

FIG. 10 is a diagram illustrating preset location information, and the modification requestor may modify the preset location information as desired.

When there is a correction of data stored in the location information providing system 100, it is preferable to perform a process of data synchronization of the data of the location information providing system 100 and the data of the portable terminal 320.

In addition, as shown in Figure 4, the location information management method according to an embodiment of the present invention, if there is a search request for the location information from the user terminal 300 connected through the communication network 200, the location requested to search corresponding thereto It further includes a location information providing step (S401 to S411) for providing information.

In the step S211, when the selected service item is a location information search (S217), the location information management server 130 transmits a predetermined location information search form (S401).

As shown in Fig. 11, the preset location information search form includes a business name / company name inputter, an address inputter, a postal code inputter, a telephone number inputter, and a business type inputter.

On the other hand, when a search requester requests a search for location information using a portable terminal 320 such as a mobile phone, the portable terminal 320 receives a search form as shown in FIG. 12.

The mobile phone user can obtain the location information of the desired target point by using the search form as shown in FIG.

The location information search requester inputs data on a search target point using the received location information search form (S403).

The data on the search target point may include at least one of a business name / company name, address, zip code, telephone number, and business type inputter to search.

Then, the location information management server 130 searches for location information on the target point requested to be searched (S405), and determines whether or not data is not provided (S407).

Not available means whether or not to disclose the location information provided by the person who provided the location information for the target point to the public.

In the case where the provision of the location information is not provided in step S407, the location information management server 130 determines whether the person requesting the search for the location information exists in the access right to the location information (S409). ).

Access to the information can be determined by the ID and password of the person providing the requested location information.

Whether the location information of the corresponding location information for the target request requested in step S407 is not provided or if the access authority for the location information is provided in step S409, the location information management server 130 searches. The location information on the requested target point is transmitted (S411).

13 and 14 illustrate a state in which location information about a target point displayed on the terminal is displayed.

In addition, as shown in Figure 5, the location information management method according to an embodiment of the present invention, if there is a request for transmission of the specific location information from the user terminal 300 connected through the communication network 200 to the other terminal, It is preferable to further include a location information transmission step (S501 to S503) for transmitting the requested location information to the other terminal.

When the location information transmission requester inputs data on a transmission target point by using the terminal 300 (S501), the location information management server 130 transmits the location information on the requested target point to the other terminal ( S503).

Of the location information providing method as described above, the remaining functions except for inputting the weakness information are possible in both the computer system 310 and the portable terminal 320.

In addition, the position information may be transmitted from the computer system 310 to the portable terminal 320, or the position information may be transmitted and received between the portable terminals 320.

In addition, the user's location information can be stored in his or her mobile terminal, and his or her location information stored in his or her mobile terminal can be transmitted to another's mobile terminal using a short message service (SMS) function. Of course it can.

The method for providing location information according to the embodiment of the present invention as described above allows the user to directly input the location information of the target point and use it to provide more accurate location information for the target point. Further, since each user can set and use location information suitable for each user, the person looking for the location of each user can provide the location information to the person looking for the location of the user in a form that the user thinks is desirable.

In addition, since the location information input by the user includes the text path information, the location information can be provided with a smaller data capacity, thereby making the location information easier to use in a portable terminal such as a mobile phone.

Furthermore, the character path information includes the reaching process for each transportation means to the target point, thereby more efficiently displaying the arrival path leading to the target point.

In addition, since the location information input by the user includes the map information, unlike the existing map data, it is possible to provide the map data that has been simplified, so that the visibility is excellent and the data traffic can be reduced.

By creating a map, you can delete some of the roads and buildings, reduce the volume of data and increase visibility, and also allow the user to select the type and location of the direction arrow, text, and location. Readability can be further improved, and positional information can be created that more accurately reflects the situation of the target point.

In addition, the method for providing location information according to an embodiment of the present invention allows the location information to be corrected, so that when the location information is incorrectly created or there is a change in the path of the target point after creation, the location information is easily created without creating new location information. Can be modified.

When the user allows the user to provide the location information, the location information is also available to a third party, thereby protecting the privacy of the user and allowing the third party to use the location information.

In addition, when there is a request for transmitting the location information from the terminal, by transmitting the corresponding location information to the other terminal, in particular, it is possible to easily exchange location information between the portable terminal.
