When the power is turned on according to the power button of the keypad 226, the microcomputer 220 controls the overall operation of the terminal by executing a program stored in an internal memory or an external memory. That is, when a call button is input following a phone number, a call is set to the corresponding phone number, and when a menu button is input, the corresponding menu screen is displayed on the LCD 227. Then, the operating environment of the terminal is set according to the selection of the menu item and the input of the setting value, and when a call is detected from the counterpart, the buzzer 228 is driven to sound a buzzer.

3A and 3B are flowcharts illustrating an example of setting a location information transmission period according to the present invention. FIG. 3A is an example of setting a location information transmission period using a menu in the terminal itself, and FIG. 3B shows an allowed subscriber. An example of setting the location information period of the designated terminal through the location information service center (106 in FIG. 1).

Referring to FIG. 3A, after pressing a menu button on the keypad of the terminal (226 of FIG. 2) to open a menu screen, a location information reporting period setting item is selected to input a location information reporting period (301 and 302). At this time, a method of selecting one of predetermined period values or a method of arbitrarily inputting a period may be used as the period input method. Next, after storing the input location information reporting period in the nonvolatile memory (224 of FIG. 2), the internal timer of the microcomputer 220 is started (303).

Referring to FIG. 3B, the setter connects to the web server of the location information service center 106 via the Internet 104 via a PC (102 in FIG. 1). After selecting the period setting item from the service menu and enters the phone number of the target terminal (312). Subsequently, if the setter is allowed through the authentication process (for example, inputting and confirming a password), the user inputs a location information collection period for the mobile terminal, and the location information service center 106 transmits the input period parameter to the communication network 108. Through the transmission to the corresponding mobile terminal (124a or 124c) (313 ~ 315). When the period setting message and the parameter value are received, the portable terminals 124a and 124c start the timer after setting the period to the corresponding parameter value (316).

4A, 4B and 4C are flowcharts illustrating an example in which the portable terminal transmits location information according to the present invention. FIG. 4A is an example of transmitting location information in a normally operating portable terminal. FIG. FIG. 4C illustrates an example of transmitting location information once when the portable terminal transitions from a communication impossible state to a communication state.

Referring to FIG. 4A, it is determined whether the location information transmission period is compared to the set period value by comparing the location information timer value (401). If the transmission period is performed, step 403 is immediately performed. Determine whether a message is received (402). When the location information transmission cycle or the real-time location information collection request is received from the network, the location information of the terminal is obtained using the location detector (403). In this case, a method for obtaining location information may use a GPS module or a propagation time difference processing module between a terminal and an adjacent base station.

Subsequently, if the location information acquisition fails after determining whether the location information acquisition is successful (404), the location information is acquired by the base station cell ID to which the corresponding terminal belongs (405). It is determined whether it is possible (406). If it is not in the communicable state, the acquired location information is stored in the memory and the process is repeated from the beginning (407). If the communicable state is transmitted, the acquired location information of the terminal is transmitted to the location information service center (408).

Referring to FIG. 4B, when the portable terminal is powered on, the terminal acquires location information of the terminal after initializing the portable terminal (411 to 413). In operation 414 and 415, the controller determines whether the communication is possible and if the communication is not possible (ie, when it is out of the call zone), the acquired location information is stored in the memory (414 and 415). If the communication is possible, the previous location information and the current location information stored in the memory of the mobile terminal is transmitted to the location information service center (416). When the power is turned on in this way, once the current location information is transmitted together with the previous location information, the normal procedure as shown in FIG. 4A is performed.

Referring to FIG. 4C, when the terminal is in a communication impossible state out of the communication right and enters the communication right, the terminal first obtains location information of the terminal (421, 422). Subsequently, the previous location information and the current location information stored in the memory of the portable terminal are transmitted to the location information service center (423). As described above, when the mobile terminal is in a state of being unable to talk and then transitions to a callable state, the mobile terminal performs the normal procedure as shown in FIG. 4A after transmitting the current location information together with the previous location information.

5 is a flowchart illustrating an example of using a location information service with a mobile terminal according to the present invention. Referring to FIG. 5, after inputting a number for accessing a location information service center, the user presses a call button or uses a short message service (SMS) to access the location information service center using a mobile terminal (501). If the connection is successful, the user selects a desired inquiry service among various services provided by the location information service center through a menu displayed on the LCD or guide voice, and requests another terminal inquiry suitable for the condition (502). For example, enter a desired search condition such as finding a club member or a hotel located closest to where you are currently located, or finding a member who can reach a certain time.

The location information service center searches the database according to the search condition and transmits the search result through the communication network, and the mobile terminal receives the search result (including registered phone number) from the location information service center (503 and 504). The received result is displayed on the LCD, and if you want to see the call, press the call button without having to dial a separate (505,506). If more than one person is found as a result of the search, select a person in consideration of his / her personal information and press the call button. When the call button is pressed, the phone number is recognized from the information received as a result of the inquiry and automatically connected to the number (507). At this time, the searcher can prevent the leakage of personal information by hiding the phone number of the searched party. As such, when the location information service is provided by using the mobile terminal of the present invention, it is possible to simply connect without having to dial the desired counterpart's number.

As described above, the present invention can efficiently provide location information-related services by transmitting the current location information of the mobile terminal according to a set period or at a time required by the location information service center. In particular, in a communication incapacity state, the position information is stored in a memory for each period, and when the communication state is possible, the movement path of the terminal can be tracked by transmitting the previous position information together with the current position information. In addition, when receiving an inquiry result in the location information service, it is very convenient to simply connect with the other party by pressing the call button without a separate dialing procedure.
