Method for providing distance measurement service using GPS function and mobile phone implementing the same {Method for serving distance information using GPS and mobile phone implementing the same}

The present invention relates to a method for providing a distance measurement service using a GPS function and a mobile phone implementing the same. More particularly, when a user designates a specific area in a mobile phone having a GPS function, the distance between the specific area and the user is arbitrarily selected. The distance information server calculates two distances and provides them as distance information to the user, and a mobile phone supporting such a method can be implemented.

Recently, with the widespread use of mobile communication services, almost all citizens are provided with one or more mobile communication services. Such mobile communication services have recently been extended to the areas such as wireless Internet service and location tracking as well as basic voice calls and text and voice message transmission.

Among these, a location tracking function using a mobile communication terminal uses a cell location registered in a home location register (HLR) and location information by a Global Positioning System (GPS). It can be implemented by the method.

Among the above-described location tracking methods, cell location information is a method of tracking the location of a mobile communication terminal according to a cell by determining a radius of a cell, that is, a radius around a base station. According to this, since there is an error of several kilometers (km) per cell, accurate location tracking is difficult. On the other hand, the use of a differential global positioning system (DGPS) system can be provided with relatively accurate position information having an error of several meters to several tens of meters. Because of the use of satellites, the accuracy is greatly improved.

Recently, by adding a GPS positioning function called "gpsOne" to the MSM 3300, Qualcomm's CDMA modem chip, a terminal (mobile communication terminal or other portable computer system) equipped with the CDMA data communication system is equipped with CDMA data communication. In addition, GPS signals from base stations or satellites can be used for fast and accurate positioning. As a result, it is also possible to receive information on the neighborhood where the mobile phone is located, even visually.

However, until now, the GPS function granted to the terminal only informs the location information, and there have been few proposals for various services using the same.

The present invention has been made to solve the above-mentioned problems, and an object of the present invention is to calculate a distance between an area input by a user and a user using a mobile phone having a GPS function and provide the same as distance information to the user. .

Another object of the present invention is to provide the user with the location information server calculates the distance between the two regions when the user inputs the names of the two regions in the mobile phone with a GPS function.

Thus, the present invention provides the user with the distance between specific locations.

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

1 is a block diagram showing the internal configuration of a mobile phone for providing a distance measurement service according to the present invention.

In order to implement the present invention, a block diagram of a mobile phone includes a control unit 100, a keypad 110, a display unit 120, a memory unit 130, an audio conversion unit 140, a wireless circuit unit 150, and a GPS processor.

The control unit 100 controls and controls all functions of the mobile phone. In the present invention, the current position is calculated from the data processed by the GPS processor 160 and the distance from the distance information server is displayed on the screen. do. In other words, if a specific region is input from the keypad, it is processed and transmitted to the wireless circuit unit 150. The wireless circuit unit receives the distance information between the region and the current mobile phone or any two regions and displays it on the screen.

The keypad 110 is composed of a function button for executing a function as an input means for transmitting a user's command to the control unit 100 and a general button for inputting only letters or numbers. It acts as an intermediary to send to.

The display unit 120 displays an information screen for notifying information of the mobile phone, a menu screen showing various functions, an input screen for inputting letters or numbers, and a result screen according to the control of the controller 100. do. Therefore, the user of the mobile phone can see it and perform the desired function.

The memory unit 130 stores a program for driving a function processed by the controller 100, a predetermined program for implementing convenience and basic functions of a user, and the like. Elements constituting such a memory unit generally include flash memory, random access memory (RAM), read only memory (ROM), and the like. The dual flash memory stores a basic real time operating system (OS) and call processing software of a mobile communication terminal, and the variables and states of these programs are read from the RAM and operated. The ROM is composed of an electrically erasable programmable read only memory (EEPROM), stores nonvolatile data that can be electrically erased or stored again, and performs input / output according to a command of a controller. The data stored in these ROMs include NAM (number assignment module) parameters that can be used semi-permanently without being erased, and other data for storage (phone number and name, text message, video, etc.). The memory is a non-volatile memory that has a high processing speed and data is preserved. When upgrading the software of a mobile communication terminal, new software is stored in this part.

According to the present invention, a program receives a specific region name from a user and transmits it to a wireless circuit unit and stores system information required by a mobile phone.

The audio converter 140 processes the voice recorded by the user of the mobile phone through the microphone as data and transmits it to the controller 100 or processes the data received from the outside to output analog voice through the speaker. In charge.

The wireless circuit unit 150 receives a telephone call or a short message sent by an external telephone through an antenna and transmits it to the control unit 100 or transmits data stored in the memory unit 130 to the caller's telephone through the antenna. Perform the function of sending. In addition, the data is transmitted or received by converting the data into a radio signal or a radio signal into data so that the GPS may process the data on the location information.

The GPS processing unit 160 simply has a function of receiving a GPS signal and transmitting it to an external GPS positioning system, and the location information calculation from the actual GPS signal is performed in a distance information server for confirming the GPS location. Of course, in calculating the positional information, the present invention is not limited thereto, and in some cases, the GPS processing unit may calculate and calculate the positional information. This is merely a difference of where the calculation method is effective and is the same in implementing the present invention.

2 is a network diagram illustrating a configuration for receiving a distance information service of a mobile phone according to the present invention.

The elements of the network for implementing the present invention include a mobile phone 200, a positioning satellite 210, a base station 220, a base station controller 230, a mobile communication switch 240, a distance information server 250, and the like. It is provided.

The mobile phone 200 includes the GPS processor described in FIG. 1, and exchanges data for location information from the satellite 210 and the base station in charge of the corresponding area.

The satellite 210 transmits the location information to the base station 220 to determine the location of the mobile phone through the process of receiving or transmitting data to the mobile phone and the base station. That is, the position tracking altitude satellite tracks the position of the mobile phone for a period of time as it orbits over the earth, and transmits position information data about latitude and longitude altitude time and the like.

The base station 220 is a type of repeater and controls the mobile communication terminal by wirelessly connecting with the personal mobile communication subscriber of the corresponding area.

The base station controller 230 is connected to the base station 220 to control the base station and is connected to the mobile communication exchange 240 through a controller matching process in the mobile communication exchange 240.

The mobile communication exchanger 240 connects the call from the base station controller 230 to the local exchange in the case of the other exchange or the local call, and connects the call through a switching operation to perform charging according to the talk time.

In response to a request from the mobile phone 200, the distance information server 250 searches for location information on a corresponding area, calculates a distance, and transmits the distance information to the mobile communication switch 240, the base station controller 230, and the base station. Through 220 is provided to the mobile phone. In addition, in response to a request from the mobile communication exchanger 240, it is also possible to search for location information on a corresponding area and provide it to the mobile phone. Accordingly, the distance information server includes a geographic information database 251 to calculate the above-mentioned distance information. This geospatial database contains the name of each region and the distance data between them. In addition, the distance information server includes a location information database 252 to provide location information.

3 is a flowchart illustrating a process of calculating and providing distance information to a place name input from a user of a mobile phone according to the present invention.

The cellular phone is in a standby mode until there is a message transmission signal from a communication device requesting a telephone call or an operation on a terminal by a user. The process of processing by the mobile phone until it is placed in the standby mode is as follows.

First, when power is supplied to the mobile phone, the mobile phone reads the necessary system information from the ROM in the memory unit 130, sets it in RAM, synchronizes with the system, and receives necessary system information from a base station located in a corresponding region. When the necessary system information is received, mobile phones exchange data with satellites to determine their current location. This process is usually enabled by positioning the satellites as they orbit around the earth, tracking the location of the mobile phone and transmitting location information data about latitude and longitude and altitude time to the base station. This is described in detail in the previously published application No. 1999-024511, "Method for Providing a Positioning Service for a Mobile Station by Attaching a GPS Terminal to Personal Mobile Communication and Mobile Communication," which will be omitted herein.

Therefore, through the above-described process, the distance information server 250 tracks the location of the mobile phone from time to time using the GPS system and receives information on the location from the mobile phone (step S300). The distance information server receiving the location information grasps and stores the current location of the cellular phone (step S310).

The distance information server grasping the current location checks whether there is a request of the target area to know the distance from the mobile phone (step S320).

In order to make such a request, a mobile phone needs a method that can be used by a user. There are many ways to identify these areas and distances. First, it is possible to configure the "distance providing service" in the menu list so that the user can select from the menu. A screen example showing the menu selected from the menu list is shown in FIG. Alternatively, for convenience of the user, it is also possible to provide a separate dedicated key button on the keypad of the mobile phone to move to the menu screen at a time without having to operate several keys. If a dedicated key button for the "distance providing service" is provided on the keypad of the mobile phone, the user can simply use the "distance providing service" function by pressing the corresponding key button. In addition, it is also possible to configure the "distance provision service" function in the form of a shortcut icon on the initial menu screen. This is just a difference in how the menu is organized, and the result is the same no matter which case you choose.

Therefore, the "distance providing service" menu is displayed on the screen by any of the above-described methods, and when the user selects a corresponding item on the menu screen, a screen for inputting a desired region name is displayed. That is, if the screen "1. Distance measurement guide" 500 is selected on the screen, a screen for inputting a region name is displayed on the screen. On this screen, the user enters the desired area name.

When such an area name is input, the mobile phone transmits it to the distance information server through the base station. The distance information server receiving the request grasps the current location area from the current location information of the mobile phone in which the location information database is stored and the location of the place name input through the mobile phone using the geographic information database 251, and the corresponding area. The distance between the cell phone and the mobile phone is calculated (step S330). For example, if the user inputs the desired area name in the "Gwanghwamun" as "Gangnam Station" with the mobile phone, the distance between "Gwanghwamun" and "Gangnam Station" is calculated and transmitted to the mobile phone. The cellular phone displays this (step S340). A screen example showing this is shown in FIG. 6B. That is, a message such as "It is 35 km from here to Gangnam station" is displayed on the screen (step S350).

4 is a flowchart illustrating a process of calculating and providing distance information of two names inputted according to the present invention.

Unlike the above-described FIG. 3, the flowchart shows a process for informing the distance between any two regions regardless of the location of the mobile phone. That is, the "distance providing service" menu is displayed on the screen by any one of the methods described in FIG. A screen example showing this is shown in FIG. 5. If you select "2. General distance measurement guide" (510) in this menu screen, a screen for entering the area name is displayed. A screen example showing this is shown in FIG. 7A. In this screen, the user inputs two desired area names (step S400). In other words, enter "Yeoksam Station" and "Kyoband" as shown in the example screen.

When such an area name is input, the mobile phone transmits it to the distance information server through the base station.

The distance information server receiving the request checks the input area name using the geographic database 251 and calculates the distance between the two areas (step S410).

The distance information server transmits the distance information indicative of the calculated distance to the corresponding mobile phone via the base station (step S420).

The cellular phone receives the distance information and displays it (step S430). A screen example showing this is shown in FIG. 7B. That is, the screen displays a message such as "The distance between Yeoksam Station and the crosswalk is 10 km."

The present invention has been described above with reference to the drawings and embodiments, but the present invention is not limited to the specific embodiments, and those skilled in the art will appreciate that many modifications and variations can be made without departing from the scope of the present invention. It will be understood that it can be done. In addition, the protection scope of the present invention will be defined by the appended claims.

According to the method and the mobile phone of the present invention, there is a convenient effect when moving a place or establishing a travel plan based on the distance information calculated by the mobile phone having the GPS function.
