이동 통신 단말기의 표준시간 표시 방법{STANDARD TIME DISPLAY METHOD FOR MOBILE COMMUNICATION DEVICE}How to display standard time of mobile terminal {STANDARD TIME DISPLAY METHOD FOR MOBILE COMMUNICATION DEVICE}

본 발명은 이동 통신 단말기의 표준시간 표시 방법에 관한 것으로, 특히 비동기 방식 이동통신 단말기(GSM/GPRS)에서 시스템의 표준시간 정보를 수신하여 디스플레이 할 수 있도록 하는 이동 통신 단말기의 표준시간 표시 방법에 관한 것이다.The present invention relates to a method for displaying a standard time of a mobile communication terminal, and more particularly, to a method for displaying a standard time of a mobile communication terminal for receiving and displaying standard time information of a system in an asynchronous mobile communication terminal (GSM / GPRS). will be.

일반적으로, 비동기 방식 이동통신 시스템인 GSM/GPRS 등의 단말기는, 동기식 CDMA 단말기와 달리 사용자가 직접 시간을 입력해 주어야 그 이후에 시계가 작동하도록 되어 있다.In general, unlike a synchronous CDMA terminal, a terminal such as GSM / GPRS, which is an asynchronous mobile communication system, requires a user to input a time directly so that the clock operates thereafter.

즉, 동기식 단말기의 경우에는 단말기 셋업 동작 중에 자동으로 단말기의 시간을 셋팅 하기 때문에, 사용자가 직접 시간을 입력해 주지 않더라도, 모든 단말기가 항상 정확한 시간을 유지하고 있다.That is, in the case of a synchronous terminal, since the time of the terminal is automatically set during the terminal setup operation, all the terminals always maintain the correct time even if the user does not input the time directly.

그러나, 비동기 방식 GSM/GPRS 단말기의 경우에는, 시스템에서 시간 정보를 보내주지 않기 때문에, 각 단말기 사용자가 직접 시간을 입력해야 하므로, 단말기마다 시간이 정확하지 않으며 또한, 단말기 온/오프 시마다 매번 시간을 입력해야 하는 번거로움이 있다.However, in the case of asynchronous GSM / GPRS terminals, since the system does not send time information, each terminal user has to input the time directly, so the time is not accurate for each terminal and the time is turned on every time the terminal is turned on or off. There is a hassle to enter.

이에 따라, 종래의 비동기 방식 GSM/GPRS 단말기는, 도1에 도시된 바와 같이 백업(backup) 배터리(BAT)를 이용하여, 전원 오프시에도 내부의 RTC(Real Time Clock)에 기록된 시간 정보가 지워지지 않도록 하고 있다.Accordingly, in the conventional asynchronous GSM / GPRS terminal, as shown in FIG. 1, time information recorded in the internal RTC (Real Time Clock) is stored even when the power is turned off by using a backup battery BAT. It is not erased.

그러나, 상기와 같이 RTC를 이용한 시간 표시는 자체 타이머에 의해 시간을 계산하여 표시하는 것일 뿐, 동기식 이동 통신 단말기와 같이 정확한 시간을 주기적으로 수신하여 표시하는 것이 아니기 때문에, 표시시간의 신뢰성이 떨어지고 사용자가 번거로워지는 문제점이 있다.However, the time display using the RTC as described above is only to calculate and display the time by its own timer, and since the exact time is not received and displayed periodically like a synchronous mobile communication terminal, the display time is less reliable and the user There is a problem that is cumbersome.

따라서, 본 발명은 상기와 같은 종래의 문제점을 해결하기 위하여 창출한 것으로, 비동기 방식 이동통신 단말기(GSM/GPRS)에서 시스템의 표준시간 정보를 수신하여 디스플레이 할 수 있도록 하는 이동 통신 단말기의 표준시간 표시 방법을 제공함에 그 목적이 있다.Accordingly, the present invention has been made to solve the above-mentioned conventional problems, and displays a standard time of a mobile communication terminal to receive and display standard time information of a system in an asynchronous mobile communication terminal (GSM / GPRS). The purpose is to provide a method.

이와 같은 목적을 달성하기 위한 본 발명은, 단말기 전원이 켜진 후 가입자 번호 등의 가입자 정보를 인식하는 단계와; 상기 가입자 인식 과정을 완료한 후, 위치 등록을 하는 동안 시스템으로부터 시간정보를 수신하는 단계와; 수신된 시간 정보로 내장 RTC 정보를 갱신하고, 그 RTC 정보에 의해 현재 시간을 디스플레이 하는 단계를 포함하여 이루어진 것을 특징으로 한다.The present invention for achieving the above object comprises the steps of recognizing subscriber information such as subscriber number after the terminal power is turned on; Receiving time information from the system during location registration after completing the subscriber identification process; And updating the embedded RTC information with the received time information, and displaying the current time by the RTC information.

본 발명에서는 비동기 이동 통신 단말의 파워-업(Power-up) 시, 시스템과 단말 간 프로토콜 메시지를 송수신할 때 시간 정보도 함께 수신하여, 내장된 시계 타이머 프로그램을 갱신함으로써, 정확한 현재 시간을 표시하도록 함을 특징으로 한다.In the present invention, upon power-up of the asynchronous mobile communication terminal, time information is also received when transmitting and receiving a protocol message between the system and the terminal, and the built-in clock timer program is updated to display an accurate current time. It is characterized by.

또한, 유휴(IDLE) 상태에서 일정시간 머물 경우, 타이머를 구동해 시간정보를 얻어와 정확한 시간 정보를 유지할 수 있도록 함을 특징으로 한다.In addition, when a certain time stay in the idle state (IDLE), it is characterized in that the timer is driven to obtain the time information to maintain accurate time information.

이하, 본 발명의 바람직한 실시예를 첨부한 도면을 참조하여 설명하면 다음과 같다.Hereinafter, with reference to the accompanying drawings, preferred embodiments of the present invention will be described.

도2는 본 발명에 따른 이동 통신 단말기의 개략적인 구성을 보인 블록도로서, 이에 도시된 바와 같이 RF 신호를 송수신 처리하기 위한 RF 신호 처리부(101)와, 단말기의 현재 시간 정보를 내부적으로 유지하기 위한 RTC(Real Time Clock,104)와, 중앙 처리 장치의 제어에 의해 각종 정보를 디스플레이 하는 디스플레이부(103)와, 전화 통화를 위해 상기 각 구성요소를 제어하는 중앙 처리 장치로 구성된다.2 is a block diagram showing a schematic configuration of a mobile communication terminal according to the present invention. As shown therein, an RF signal processor 101 for transmitting and receiving an RF signal and internally maintaining current time information of the terminal are shown. RTC (Real Time Clock) 104, a display unit 103 for displaying a variety of information under the control of the central processing unit, and a central processing unit for controlling each of the components for a telephone call.

여기서, RTC(104)는 이동 단말기의 현재 시간 정보를 내부적으로 유지하고 있는 장치로서, 중앙 처리 장치(102)의 제어에 따라 유지하고 있는 현재 시간 정보를 설정. 갱신하며, 한번 시간이 설정되면 그 시간정보에 따라 현재 시간을 계속 유지해 가고, 또한 중앙처리 장치의 요청에 따라 유지하고 있는 현재 시간 정보를 중앙처리 장치로 출력하기도 한다.Here, the RTC 104 is a device that internally holds the current time information of the mobile terminal, and sets the current time information held under the control of the central processing unit 102. When the time is set, the current time is continuously maintained according to the time information, and the current time information maintained at the request of the central processing unit is also output to the central processing unit.

다음, 도3은 본 발명에 따른 이동 통신 단말기의 표준시간 표시 방법을 보인 순서도로서, 이에 도시된 바와 같이 단말기 전원이 켜지면(S101), 가입자 번호 등 가입자 인식과정을 거친 후(S102), 내장된 RTC 정보를 읽고(S103) 시스템과 단말기 RF처리장치를 통해 Layer3 메시지 형태로 시간 정보를 수신한다(S104).Next, Figure 3 is a flow chart showing a standard time display method of a mobile communication terminal according to the present invention, when the terminal power is turned on as shown in (S101), after the subscriber identification process such as subscriber number (S102), built-in The received RTC information is read (S103) and time information is received in the form of a Layer3 message through the system and the terminal RF processor (S104).

상기와 같이 수신된 시간 정보를 이용하여 중앙처리 장치는 내장 RTC 정보를 갱신하고(S105), 필요한 경우(시간을 표시하고자 하는 경우) RTC로 시간 정보를 요청하고(S106), 그 시간 정보를 수신하여(S107) 디스플레이부에 현재 시간을 표시한다(S108).Using the received time information as described above, the central processing unit updates the built-in RTC information (S105), requests time information from the RTC if necessary (if it is desired to display the time) (S106), and receives the time information. In step S107, the current time is displayed on the display unit (S108).

이때, 상기 단말기 전원이 켜지고 가입자 번호 등 가입자 인식과정을 거친 후 위치 등록(Location update)을 하는 동안, 시스템 측은 도4에 도시된 바와 같은 표준규격(3GPP)에 명시된 3계층(Layer3)인 MM(Mobility Management) 절차 중 정보 메시지(Information Message)를 단말기로 보낸다.At this time, while the terminal is powered on and undergoes a location update after the subscriber identification process such as the subscriber number, the system side has an MM (Layer 3) layer 3 specified in the standard 3GPP as shown in FIG. Mobility Management) sends an information message to the terminal during the procedure.

단말기는 수신한 "MM Information message" 정보 중, 도5에 도시된 바와 같은 "Universal time and local time zone"을 이용해 시간 정보를 디스플레이부에 표시하고 내장된 RTC에 업데이트 시킨다.The terminal displays time information on the display using the "Universal time and local time zone" as shown in FIG. 5 among the received "MM Information message" information and updates the embedded RTC.

만약, 시스템측으로부터 시간 정보를 받지 못하면 내장된 RTC의 정보를 디스플레이부로 보내 출력하도록 하고, MM state가 유휴(IDLE) 상태로 일정기간 머물 경우, 일정한 주기로 시스템 측이 단말로 정보 메시지(Information Message)를 보내도록 해 항상 정확한 표준시간을 유지하도록 한다.If the time information is not received from the system side, the embedded RTC information is sent to the display unit for output, and if the MM state stays in the idle state for a predetermined time, the system side sends an information message to the terminal at regular intervals. Ensure that you always keep the correct time.

이상에서 설명한 바와 같이 본 발명 이동 통신 단말기의 표준시간 표시 방법은, 비동기 방식 이동통신 단말기(GSM/GPRS)에서 시스템의 표준시간 정보를 수신하여 디스플레이 할 수 있도록 하는 효과가 있다.As described above, the standard time display method of the mobile communication terminal of the present invention has the effect of receiving and displaying the standard time information of the system in the asynchronous mobile communication terminal (GSM / GPRS).
