System and method for providing location information using phone number in location-based service {SYSTEM AND METHOD FOR PROVIDING LOCATION INFORMATION USING PHONE NUMBER IN LOCATION-BASED SERVICE}

The present invention relates to a location information providing system and a method for providing location information using a phone number in a location-based service (LBS), and more particularly, to express location information using a special key and a phone number. The present invention relates to a location information providing system and a location information providing method using a phone number in a location based service.

Location-based services are services that provide location information related to the location based on the location specified by the user. In order to implement such a location-based service, a method for representing and obtaining location information is required. According to the related art, location-based service providers each define a method of representing location information, a user inputs location information by the defined expression method, and the location-based service provider provides an actual location from the location information. Each method implements a search for. That is, since the representation and the acquisition method of the location information are different for each location-based service, each service provider has a problem of implementing such a service repeatedly.

In order to express the location information, an address, a main facility, a coordinate system, etc. may be used. Expressing location information in this way is very inconvenient and cumbersome for the user. In addition, there is a problem that a method of expressing location information for each location-based service is not uniform. When a user of a location-based service expresses location information by using an address, a main facility, and a coordinate system, the location-based service must have a method for retrieving the actual location required by the actual service from the user's input. do. For example, if a user enters location information through a major facility, the service must be aware of the actual location of the entered major facility. Therefore, each location-based service provider has a difficulty in maintaining and managing information on the main address facilities and the like for retrieving location information as well as maintaining and managing their own contents.

On the other hand, as a prior patent on location-based services, Korean Patent Application No. 2002-22200 (Application Date: April 23, 2002) has been applied for "destination related information search system and method using a location code". The preceding patent has an operation server having a wired / wireless terminal client and a location code database connected to the terminal client via a network and including a location code corresponding to respective destinations, wherein the operation server is generated from a location code database. A destination-related information retrieval system that provides the destination destination-related content to the terminal client via on / offline, and the terminal client transmits the location code to the operation server with reference to the provided destination code-containing destination-related content. It is about. In the above patent, a location code using a phone number is represented by a 12-digit number, and there is a problem that it can be used only in a service capable of confirming the location code. In addition, in order to use the location code in the prior patent, there is a difficulty that the service provider separately constructs, maintains and manages the geographic information content for the location code.

As another prior patent, Korean Patent Application No. 1998-51260 (application date: November 27, 1998) has been filed a "method and system for location information service using a telephone number". The preceding patent relates to a location information service system including a geographic information DB system, an information service server, a user terminal, and a communication system, and provides location information even if a phone number of the place is known for location information of a place to be visited. do. However, even in the preceding patents, the service provider has a difficulty in constructing, maintaining, and managing a phone number DB and a geographical information DB in order to provide location information corresponding to the phone number.

The present invention is to solve the above-mentioned technical problem, and expresses the location information by using a special key and a phone number, if the phone number is a mobile phone to retrieve the location information from the location acquisition gateway of the mobile carrier In the case of a landline phone, the location information is retrieved and provided from the wireline carrier's location information center so that the provider of the location-based service does not need to establish, maintain, and manage a separate location information database. An object of the present invention is to provide a location information providing system and a location information providing method.

Location information providing system according to the present invention for achieving the above object is connected to the wireline carrier location information center connected to access the landline subscriber database, the mobile located within the service radius between the mobile terminal and the mobile communication exchange A mobile communication base station which transmits and receives a signal for performing a call setup and a call function of the terminal and transmits a signal of a combination of a predetermined special key and a telephone number from the mobile terminal; When the signal combining the special key and the telephone number is input from the mobile terminal through the mobile communication base station, only the telephone number is separated, and the location information search request is performed according to whether the number is a landline or mobile telephone number. A location-based service platform for transmitting a response result of the search request to the mobile terminal through the mobile communication base station; And a location acquisition gateway that searches for location information of the mobile phone and provides the result to the location-based service platform when the phone number separated from the location-based service platform is a mobile phone number.

In most location-based services, since the location of a destination to be searched by the user has a phone number, the user can express the location information of the destination using the phone number. In the present invention, a method of expressing location information is as follows. When the user enters the phone number of the destination and presses the call button, the user enters the phone number with the special key, for example, the "#" button, and presses the call button. Location information is retrieved. If the location information is expressed by attaching a special key "#" in front of the phone number in this way, the location information can be easily stored because the user can express the location information only by the phone number of the corresponding destination. In addition, since the location information can be easily entered by using the phone number stored in the mobile terminal or by entering the phone number, it is expected to be widely used in various location-based services.

The location information representation method proposed by the present invention is not intended to be a separate application service level, but is intended to be installed as a basic function of mobile communication. For example, by pressing the special key "*" and No. 88 in the mobile terminal, when the special key "#" and the telephone number are pressed, the location of the mobile communication network is similarly connected to the voice mail service of the mobile communication network. To automatically connect to information services. Accordingly, as shown in FIG. 1, the location information may be obtained by inputting a special key "#" and a phone number and pressing a call button in the mobile terminal, rather than a separate service. The special key may be selected from input keys of the mobile terminal, and may be set in advance such as "#" or "*".

2 illustrates an example of inputting location information in a location information providing system according to an exemplary embodiment of the present invention. In the case of the route search service, the location information may be expressed using the special key "#" and the telephone number if the telephone number of the origin and destination is known. In the case of the location search service, an address, a place name, etc. may be used to input location information, and a special key "#" and a phone number may be used. In the present invention, the location search service means outputting the information of the surrounding area with the map with respect to the location information input by the user.
