The method using the cell location information with the terminal has a radius of the cell, that is, the error of about several km, so it is difficult to accurately track the position. However, if the GPS or DGPS (Differential GPS) system is used, the error of several m to tens of meters Branches can provide relatively accurate location information.

Recently, the GPS positioning function "gpsOne" has been added to Qualcomm's CDMA modem chip, MSM 3300, so that a terminal (mobile communication terminal or other portable computer system) equipped with the CDMA modem is connected to a reference station or GPS signals from satellites enable fast and accurate positioning.

However, until now, the GPS function provided to the terminal only informs the position information and the time of day, and has not been proposed for various services using the same.

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

1 is a functional block diagram of a mobile communication terminal for providing a location information service according to the present invention.

GPS receiver which receives and demodulates a GPS signal in addition to including an input unit 110, an output unit 120, a storage unit 130, a wireless transmitter / receiver 140, and a controller 150 like a general mobile communication terminal ( 160).

The controller 150 should additionally include a function for calculating a current position from the data demodulated by the GPS receiver 160 and a function for implementing a calculation algorithm for providing various location information services according to the present invention. . Of course, the GPS receiver of the terminal may simply have a function of receiving a GPS signal and transmitting it to an external GPS positioning system, and calculating position information from the actual GPS signal may be performed in the GPS positioning system. This calculation algorithm is described in more detail below.

2 is a flowchart illustrating a method of providing a location information service according to the present invention.

First, the mobile communication terminal sets the storage period by receiving and storing the location information storage period information input by the user (S210). At this time, a storage initial time for starting storage may be further input.

The storage period may be arbitrarily set from a few hours to several days depending on the purpose of utilizing location information, but it is preferable to set the storage period shortly to provide accurate and complete service.

After checking the time of the terminal, the GPS receiver is received at every storage cycle interval from the initial time to receive the GPS position information and stored in the storage of the terminal (S211). Of course, when using a separate external GPS positioning system, the terminal may transmit the received GPS signal to the GPS positioning system, and receive and store the position information calculated and transmitted by the GPS positioning system.

The extracted location information may be location location information such as longitude and latitude, and may further include administrative location information in addition to the location location information by interworking with other services that correspond to the location location information and the administrative location information. Administrative location information refers to administrative dong / gu number and important facilities / buildings. At this time, the location information is stored in the form of a table having an appropriate field, which will be described in detail with reference to FIG. 3.

When the user requests the location information service, the following four possible services are provided as a list, and one of them is selected.

First, when the selected location information service is a movement route service (S220), the user inputs a time interval for displaying the movement route (S221). That is, an initial time for displaying the initial position of the movement route and a final time for displaying the final position are input. For example, if you want to know the travel route from 12:30 to 13:30 on November 15, 2001, enter the initial time: 11151230 (mmddhhmm order) and the last time: 11151330.

Then, the controller of the terminal searches for the location information stored in the storage unit, extracts the location information corresponding to each storage cycle time from the inputted first time to the final time, and outputs it in a text format or an image format (S222). , S223). The text output can be performed by arranging the extracted location information on the terminal screen in chronological order, and the image output can be performed on a map image previously stored in the terminal or downloaded from an external server (a swap server or a server of a mobile communication service provider). This can be done by indicating the corresponding position of in chronological order. Since a technique of displaying location information on a map is widely known, its detailed description will be omitted.

If the service selected by the user is a "moving speed providing service" (S230), the user may input or select a time interval or a location interval for which speed calculation is required (S231). Although the input of the time interval or the position interval may be made through the keypad, it is also possible to select the initial time (initial position) and the last time (final position) for which speed calculation is required from the list of previously stored position information. This will be described in detail with reference to FIG. 4.

Next, the control unit of the terminal calculates the moving speed between the corresponding time interval or position interval using the stored speed calculation algorithm and outputs it on the screen (S232, S233). Such a speed calculation may be calculated by calculating a distance between two locations as described below with respect to a "conversion distance service", and then dividing the distance by the time taken to move between the two locations.

If the service selected by the user is a "conversion distance service" (S250), as described above, the user inputs or selects information about two positions (first position and final position) whose distance is desired (S251). The control unit searches for the location information stored in the storage unit, extracts information on the initial position and the final position, and calculates and outputs the distance between the two positions using the same (S252, S253). This can be done with the same process. The distance of 1 ° longitude is 96.5km at latitude 30 °, 85.4km at 40 ° latitude, and the distance between 1 ° latitude is about 110km. Minutes 00 seconds, E125 hours 00 minutes 00 seconds) and (N30 degrees 10 minutes 00 seconds, E125 hours 10 minutes 00 seconds) can be calculated by the following equation (1).

This distance is, of course, the straight line distance between the two positions. Therefore, when only the initial position and the final position are set, the linear distance between the two positions is obtained regardless of the intermediate route.

Otherwise, when the initial position and the final position are determined, all position information between the two positions corresponding time is extracted, and each position is set to one node to obtain the actual distance of the movement route. In the above example, if there is another position information between the initial position (A) and the final position (C), and the longitude and latitude of the position (B) is (E125: 10: 00, N30, 00:00) The actual moving distance can be obtained as follows.

Therefore, the shorter the storage period will be able to calculate the more accurate path and conversion distance.

When the service selected by the user is a "consumption calorie calculation service" (S240), similarly to the above, the user inputs an initial time (or an initial position) and a final time (final position) desired for the calculation (S241). By using all the position information existing between two times (or positions), the moving distance between the two positions is calculated, and the moving speed is calculated. Such movement distance and movement speed can be obtained by the above-described method.

When the movement path and the movement speed are obtained, for example, calorie consumption according to the movement may be calculated by using Equation 3 below (S242).

The above formula consumes about 4m / s of calories as much as weight x distance (km) and calories as much as about 1m / s and consumes calories as much as weight x distance (km) / 2 Kcal. Derived from historical data.

Of course, these calorie calculations may vary in other forms and may allow the user to pre-store their weight for more accurate calculations.

Since this calorie calculation is only applicable to two-dimensional movement, it may not provide accurate information, but may provide an approximate calorie consumption. In addition, after a certain exercise such as jogging or walking with a terminal, using the above services will be able to perform accurate calorie calculation.

In addition, in order to more accurately calculate calories, only the moving distance less than a predetermined speed may be reflected in the calorie calculation. For example, since the upper limit of the movement speed of a person is about 5 to 10 m / s, for example, when the movement speed is 20 m / s (72 km / h), it is moved by a vehicle or other transportation means.

Conversion distance calculation, calorie calculation, and the like are not necessarily limited to the above-described examples, and other algorithms may be used.

3 illustrates an example of a location information storage table stored in a storage unit of a terminal in the present invention.

The location information storage table should have a time, (location) location field, and may further include an administration location information field corresponding to the location location.

The time field displays a time for each storage period set by the user, and the location information field stores the location information surveyed by the GPS receiver of the terminal at the corresponding time. The location information is mainly composed of longitude and latitude information, and the longitude is composed of the longitude (E) and west longitude (W) and five to seven digits, and the latitude is north latitude (N) and south latitude (S). It consists of 4 to 6 digits. Numbers in longitude represent "hours", "minutes" and "seconds" in order, and numbers in latitude represent "degrees", "minutes" and "seconds".

In the corresponding administrative location information field, administrative location information such as the location, location, or important facility corresponding to the location location is stored. The correspondence between the location location and the administration location can be achieved by referring to a previously stored geographic information database. .

View storage location information list” of FIG. 4A is selected and is displayed on the terminal screen in the form of location information or summary location information similar to the table of FIG. Of course, if one or more of the location information is selected, the location on the map, it may be able to provide information on the service companies (restaurants, cinemas, etc.) for each industry in the vicinity.

4C is a screen in the case where " 3. Moving route display service " of FIG. 4A is selected, specifying the first time (first position) for which the moving route is to be known. In this example, one of the stored location information is selected without inputting the first time. After this step, the final time (final position) is likewise specified in the same way.

When the initial time (location) and the last time (location) are specified, as shown in FIG. 4D, the movement path may be displayed as text or as a map (image). If the "2. Display on the map" item is selected here, as shown in FIG. 4E, a path or a position at each time is displayed on the map image. In this example, since the storage period is 15 minutes, only the positions of ① and ② are displayed and there is no information about the intermediate positions. However, if the storage period is shorter, more accurate movement paths can be displayed.

Selecting "5. Conversion distance display service" of Figure 4a and specifying the two location information to know the distance, similar to Figure 4c, the distance between the two positions is calculated by the above-described conversion distance calculation algorithm and Is output together.

FIG. 5B is an output screen in the case of selecting “4. Moving speed display service” of FIG. 4A. Here, two positions (or time) for which the speed is to be known should be specified similarly to that of FIG. 4C.

FIG. 5C is an output screen when selecting “6. Consumption calorie display service” of FIG. 4A. Here, two positions (or time) to know the consumption calorie should be specified similarly to those of FIG. After calculating the distance, the calories burned are calculated and output based on the calorie calculation algorithm described above.
