A microprocessor for controlling information to be output through the LCD display while ringing the alarm bell through the speaker A mobile communication terminal that periodically provides location information using a terminal-based GPS service comprising a. The method of claim 6, The road guidance application receives the server connection period from the user, and when the server connection period arrives, the mobile communication terminal accesses the LBS platform through the mobile communication network, and the LBS platform is received from the mobile communication terminal. The location information is transmitted to a map server, and the map server generates the map in a predetermined range based on the location of the mobile communication terminal using the received location information, and transmits the map through the LBS platform and the mobile communication network. A mobile communication terminal providing location information periodically by using a terminal-based GPS service, characterized in that the transmission to the mobile communication terminal. The method of claim 6, The GPS receiver is a mobile communication terminal that periodically provides location information by using a terminal-based GPS service, characterized in that installed in the modem chip for the CDMA digital signal processing and call processing in the mobile communication terminal. The method of claim 6, The flash memory stores an operating system (OS) software having a real-time processing function for the operation of the mobile communication terminal and call processing software for processing a function related to call processing. A mobile terminal for providing location information periodically using the. In the method of providing location information periodically using a mobile communication terminal in a terminal-based GPS service system, (a) receiving, from a user, appointment information including an appointment location, an appointment time, a departure time, and a repetition time for setting a server connection period, and receiving a selection input of an alarm bell ringing at each set period; (b) downloading a map of the appointment location before the departure time arrives; (c) displaying the map downloaded at the departure time and displaying a menu for selecting appointment place additional information together with the map; (d) receiving a selection of the selected appointment place additional information and displaying the appointment place additional information together with the map; (e) periodically ringing the alarm bell according to the setting of the repetition time, and displaying a screen including the remaining distance from the location of the user and the appointment place on the map; And (f) determining whether to continue receiving the location providing service from the user when the appointment place is reached or the appointment time has passed. Method for periodically providing location information in the terminal-based GPS service system using a mobile communication terminal comprising a. The method of claim 10, In the step (a), the appointment information is periodically deleted by the user by selecting a menu or requesting retransmission of the appointment information. The terminal-based GPS service system periodically provides location information. How to. The method of claim 10, In the step (d), the method of displaying the appointment place additional information includes a method of providing a selection screen by moving a screen using a scroll bar, and a method of providing a selection screen by switching screens. Method for periodically providing location information in the terminal-based GPS service system using. The method of claim 10, In the step (f), if the location providing service continues to receive the alarm ring periodically, and displays the screen including the location of the user and the remaining distance to the appointment place on the map, the location providing service If not, the method for periodically providing location information in the terminal-based GPS service system using a mobile communication terminal, characterized in that to terminate the location providing service.
