Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

In the example of using a postal code as location information, as shown in FIG. 2, the location coordinates corresponding to each postal code are set and stored, and the location coordinates corresponding to the postal codes of the customer and the service provider are provided according to the service request. Save to memory.

In the position coordinate conversion step 30 of FIG. 1, receiving a postal code from a database of a customer and a service provider, converting the position coordinate of longitude and latitude into a position coordinate of the customer and storing the position coordinate of the customer 40 and the position coordinate of the service provider. In step 50 of storing the position coordinates in the memory device, the method stores the comparison distance between the customer and each service provider in the same manner as in the example of FIG. Provides a system and method.

As a method of calculating the comparison distance using the stored position coordinates, it can be calculated through a mathematical method using the coordinates of a sphere. In the following description, a plane coordinate system for measuring a distance by recognizing it as a plane is illustrated in FIG. 3. It will be described in more detail below.

As shown in Fig. 3, the position coordinate corresponding to the customer's location information is located at longitude 127 degrees 03 minutes 40 seconds latitude 37 degrees 30 minutes 25 seconds, and the position coordinate corresponding to the service provider is longitude 127 degrees 01 minute 40 seconds latitude. Located at 37 degrees 30 minutes 00 seconds. The longitude difference between the customer and the service provider is 00 degrees 02 minutes 00 seconds and the latitude difference is 00 degrees 00 minutes 25 seconds. A fixed variable for the distance between 1 degree and 30 degrees north latitude, the difference between 1 degree of longitude and 91,290m for 1 degree longitude and 110,941m for 1 degree of latitude is reflected in the calculation, and the straight line distance between the point of customer and service provider is simplified to 3,752m. The calculated value can be obtained and adopted as a future comparison distance.

In addition, location information corresponding to an administrative unit may be used, such as location information corresponding to a postal code.

In more detail, for example, as shown in FIG. 5, a comparison distance (a position coordinate corresponding to a point located in Seoul, Busan, Daegu, Daejeon, Gwangju, Jeonju, Chuncheon, and a position coordinate corresponding to a customer) may be compared. If L1, L2, L3, L4, L5, L6, L7) is obtained, the following comparison distance can be obtained.

Comparative distance example: L3 <L4 <L2 <L6 <L1 <L7 <L5

It is a system and method for sorting information of each point based on a comparison distance between a customer and each service provider by improving a method of arranging points in administrative units or alphabetically using the above-described comparison distance.

In addition, as a method of recognizing the location information of the non-member customer whose location information is not stored, (a) directly inputting the location coordinates (longitude and latitude), (b) entering the postal code or the name of the administrative unit How to retrieve the information (c) How to store the location data on the customer's computer or install a location information transmission program to transmit the location information according to the request of the service (d) In the case of a fixed ip user location corresponding to the fixed ip Method of setting, storing and transmitting the information (e) Method of transmitting the location information of the connected mobile phone base station when making a phone call using a mobile phone (f) There is a method of directly inputting from the map of the screen using the GIS service of the Internet.

In detail, the method for recognizing the location information includes (a) a method for directly inputting a location by directly inputting location coordinates acquired by a customer and a service provider using a map or a GPS system, that is, longitude and latitude.

(b) The customer enters the postal code or the name of the administrative unit through the input window, and then sends it.

(c) As a method of storing the location information on the customer's computer, as shown in FIG. 5, when the customer connects to the network including the Internet, the service provider confirms the location information on the customer's computer and does not have the location information. If the customer enters an address or postal code, location information is generated and stored in the customer's computer. Location information stored in the customer's computer is a system and method for transmitting location information from the service provider's computer when there is a service request without a separate login process.

In more detail, in the step (s0) of requesting service to the customer service provider, the service provider requests location information from the customer (s1) and determining the existence of the location information file on the customer's computer (s2). In the case of having the location information, the service provider provides a service to the customer through the step of receiving the location information (s3) (s4). If the location information file does not exist in the customer's computer, the customer transmits the location information file to the customer's computer (s6) through the step of inputting the location information to the service provider (s5) and the location information on the customer's computer. The location information is provided to the service provider through the step of installing the file (s7).

(d) In case of the customer using the fixed ip, the fixed ip is transmitted in the address registration process and the location information corresponding to the fixed ip is stored, and after the customer requests a service, the fixed ip registered by checking the customer's fixed ip If it is identified as ip, it is a system and method used for calculating the comparison distance using location information corresponding to the registered fixed ip.

(e) To identify the customer's location information, the server creates a specific variable and displays that variable to the customer, then the customer calls the service provider and enters the created variable. The present invention provides a system and method for identifying a customer through a variable and converting the location information of the connected intermediary base station to the customer's location information when the customer calls.

(f) Through the screen displayed to the customer by using the GIS service of the Internet, the customer designates the location on the map and stores the information of the designated location and provides the system and method used for the comparison distance calculation.

By setting and storing the serviceable range of each service provider and comparing the stored setting range with the comparison distance between the customer and the service provider, it is possible to provide service availability. For example, in more detail in Figure 6, pizza delivery box (3,000m), rent-a-car (5,000m), Chinese food (1,000m) store the service setting distance and the customer and service according to the customer's service request By calculating the comparison distance of the provider by the method described above, the comparison distance between the pizza delivery box (2,000m), the rental car (4,600m), and the Chinese food bottle (1,400m) can be obtained, as shown in FIG. Service availability is provided according to a comparison between distance and service setting distance, and service provider information can be provided separately.

In the above-described part, the service provider is a provider who provides information through a network or the Internet, and may mean a subject of server operation, and the customer includes a client who is connected to the network or the Internet to request a service.

As described above, the following effects may be obtained by a system and a method for providing a comparison distance between a customer and a service provider according to the present invention.

Since the service provided on the offline basis is highly dependent on the distance between the customer and the service provider, the customer may search for a branch by first indicating the point closest to the customer in the franchise serviced through multiple branches. It can reduce the process of.

In addition, in a method of displaying a search result such as a search engine and a yellow page, a service provider close to a customer may be sorted first and the service provider may be displayed together.

By saving and transmitting the customer's location information, you do not have to enter a separate login or location information when you receive the service.
