Abstract

PURPOSE: A method for automatically setting an RTC(Real Time Clock) of a dual mode terminal is provided to set the current time with the real-time information without an RTC chip by receiving the real-time information from a base station through a synchronous modem and transmitting the real-time information through an asynchronous modem. CONSTITUTION: The real-time information is received from the base station through the synchronous modem. The synchronous modem is turned of after transmitting the real-time information, and the asynchronous modem sets the current time according to the real-time information received from the synchronous modem. If the asynchronous modem misses the real-time information received from the synchronous modem, the synchronous modem is turned on. The synchronous modem receives the real-time information from the base station and transmits the real-time information to the asynchronous modem again.

Description

듀얼모드 단말기의 ＲＴＣ자동설정방법{METHOD FOR RTC AUTO SETTING DUAL MODE TERMINAL}RCT automatic setting method of dual mode terminal {METHOD FOR RTC AUTO SETTING DUAL MODE TERMINAL}

본 발명은 듀얼모드 단말기의 RTC(Real Time Clock)자동설정방법에 관한 것으로, 특히 비동기식 모뎀은 시간정보를 실시간으로 입력받는 동기식 모뎀으로부터 시간정보를 전송받아 RTC칩 없이도 시간설정을 할 수 있도록 한 듀얼모드 단말기의 RTC자동설정방법에 관한 것이다.The present invention relates to a method for automatically setting a real time clock (RTC) of a dual-mode terminal. In particular, an asynchronous modem receives time information from a synchronous modem that receives time information in real time, thereby enabling time setting without an RTC chip. The present invention relates to an RTC automatic setting method of a terminal.

일반적으로, 이동통신 단말기의 방식에는 미국방식의 동기식과 유럽방식의 비동기식이 있어, 동기식을 지원하는 이동통신 단말기를 비동기식으로 서비스하는 국가나 지역에서는 사용할 수가 없다.In general, there are two types of mobile communication terminals, which are US synchronous and European asynchronous, and thus cannot be used in a country or region that asynchronously serves a mobile communication terminal supporting synchronous.

이러한 이유로, 최근 상기 동기식과 비동기식을 지원하는 듀얼모드 단말기의 기술이 개발되고 있는 추세이다.For this reason, recently, a technology of the dual mode terminal supporting the synchronous and asynchronous has been developed.

듀얼모드는 특징은 동기식 모드를 지원하는 국가에서 비동기식 모드를 지원하는 국가로 이동해서는 비동기식 모드로 전환, 또는 비동기식 모드를 지원하는 국가에서 동기식 모드를 지원하는 국가로 이동해서는 동기식 모드로 전환하여 자유로운 통화가 가능하다.Dual mode is characterized by switching from a country supporting synchronous mode to asynchronous mode to asynchronous mode, or from a country supporting asynchronous mode to a synchronous mode to a synchronous mode. Is possible.

이러한, 듀얼모드 단말기는 비동기식 모뎀과 동기식 모뎀을 각각 구비하고, 사용자가 어떠한 모드에서 통화가능하도록 하며 시간정보를 제공한다.Such a dual mode terminal is provided with an asynchronous modem and a synchronous modem, respectively, and allows the user to talk in any mode and provides time information.

이때, 동기식 모뎀은 RTC칩을 구비할 필요없이 기지국으로부터 주기적으로 실시간정보를 수신함으로써, 사용자가 번거롭게 따로 시간을 설정할 필요가 없다.In this case, the synchronous modem periodically receives real-time information from the base station without having to provide an RTC chip, so that the user does not need to set time separately.

이와는 다른, 비동기식 모뎀은 사용자가 직접 RTC칩에 현재 시간을 설정해야한다.In contrast, asynchronous modems require the user to set the current time directly on the RTC chip.

이처럼, 듀얼모드의 동기식과 비동기식 모뎀을 통해 각각 수신한 시간정보는 사용자에게 실시간과 통화시간(통화시작/종료시간, 부재중 전화 수신시간) 및 단문메시지 및 음성메시지 수신시간등을 제공한다.As such, the time information received through the dual mode synchronous and asynchronous modems provides the user with real time and talk time (call start / end time, missed call reception time), short message and voice message reception time.

그러나, 상술한 종래 동기식 모뎀은 시간정보를 기지국과 주기적으로 수신하는 반면 비동기식은 RTC칩을 반드시 구비하여 사용자가 직접 시간설정을 따로 해주어야 하는 문제점이 있다.However, the conventional synchronous modem has a problem in that the time information is periodically received with the base station, whereas the asynchronous type must be provided with the RTC chip so that the user sets the time separately.

따라서, 본 발명은 상기와 같은 문제점을 해결하기 위하여 창안한 것으로, 동기식 모뎀을 통해 기지국으로부터 실시간정보를 수신하여 음역지역에서 시간을 가지는방식으로 동기식에서 시간값을 쓸 수 있는 방법을 이용하여 비동기식 모뎀으로 실시간 정보를 전송함으로써, 시간정보를 수신하여 시간설정을 하기 위해 반드시 필요한 RTC칩 없이 실시간 정보로 현재시간을 셋팅할 수 있도록 한 듀얼모드 단말기의 RTC자동설정방법을 제공함에 그 목적이 있다.Accordingly, the present invention has been made to solve the above problems, asynchronous modem using a method that can be used to write the time value in the synchronous manner by receiving real-time information from the base station through the synchronous modem to have time in the transliteration region. It is an object of the present invention to provide a method of automatically setting a RTC of a dual mode terminal that enables the current time to be set as real time information without an RTC chip necessary for time setting by receiving real time information.

도 1은 본 발명 듀얼모드 단말기의 RTC자동설정방법을 보인 흐름도.1 is a flow chart showing a method for automatically setting the RTC of the dual-mode terminal of the present invention.

상기와 같은 목적을 달성하기 위한 본 발명은, 동기식 모드와 비동기식 모드를 지원하는 듀얼모드 이동통신 단말기에 있어서, 동기식 모뎀을 통해 기지국으로부터 실시간 정보를 수신하는 제1 단계와;According to an aspect of the present invention, there is provided a dual-mode mobile communication terminal supporting a synchronous mode and an asynchronous mode, comprising: a first step of receiving real-time information from a base station through a synchronous modem;

상기 동기식 모뎀은 상기 수신한 실시간 정보를 비동기식 모뎀으로 전송하고, 그 전송된 실시간 정보에 따라 현재 시간을 설정하는 제2 단계로 이루어진 것을 특징으로 한다.The synchronous modem has a second step of transmitting the received real time information to the asynchronous modem and setting a current time according to the transmitted real time information.

이하, 본 발명에 따른 일실시예를 첨부한 도면을 참조하여 상세히 설명하면 다음과 같다.Hereinafter, an embodiment according to the present invention will be described in detail with reference to the accompanying drawings.

도 1은 본 발명 듀얼모드 단말기의 RTC자동설정방법을 보인 흐름도로서, 이에 도시된 바와 같이 동기식 모드와 비동기식 모드를 지원하는 듀얼모드 이동통신 단말기에 있어서, 동기식 모뎀을 통해 기지국으로부터 실시간 정보를 수신하는 제1 단계와;1 is a flowchart illustrating a method for automatically setting an RTC of a dual mode terminal according to an embodiment of the present invention. In the dual mode mobile communication terminal supporting a synchronous mode and an asynchronous mode, a real time information is received from a base station through a synchronous modem. A first step;

상기 동기식 모뎀은 상기 수신한 실시간 정보를 비동기식 모뎀으로 전송하고, 그 전송된 실시간 정보에 따라 현재 시간을 설정하는 제2 단계로 이루어진 것으로, 이와 같이 구성된 본 발명의 동작을 설명하면 다음과 같다.The synchronous modem has a second step of transmitting the received real time information to the asynchronous modem and setting a current time according to the transmitted real time information. The operation of the present invention configured as described above will be described below.

먼저, 동기식 모뎀과 비동기식 모뎀의 전원을 온(ON)하는 순간, 동기식 모뎀은 기지국(BS)으로부터 시간정보를 주기적으로 수신하여 비동기식 모뎀으로 시간정보를 전송한후, 상기 동기식 모뎀은 전원을 일정시간후에 오프(OFF) 한다.First, when the power of the synchronous modem and the asynchronous modem is turned on, the synchronous modem periodically receives the time information from the base station BS and transmits the time information to the asynchronous modem. Turn off later.

이에, 비동기식 모드는 수신한 시간정보를 가지고 현재시간을 셋팅하여 사용자에게 시간정보를 제공한다.Accordingly, the asynchronous mode provides time information to the user by setting the current time with the received time information.

이때, 비동기식 모뎀이 동기식 모뎀으로부터 시간정보를 받지 못하고, 그 시간정보를 분실했을 경우, 중앙처리기(MSM)는 다시 동기식 모뎀의 전원을 온시켜 그 동기식 모뎀이 기지국(BS)으로부터 실시간 정보를 수신할 수 있도록 하여 비동기식 모뎀이 동기식 모뎀을 통해 실시간 정보를 수신할 수 있다.At this time, if the asynchronous modem does not receive the time information from the synchronous modem, and the time information is lost, the central processing unit (MSM) turns on the synchronous modem again and the synchronous modem receives the real time information from the base station (BS). This allows the asynchronous modem to receive real-time information through the synchronous modem.

따라서, 본 발명은 비동기식 모드인 경우의 지역에서 시간정보를 수신하기 위해 동기식 모뎀을 이용함으로써, 비동기식 모뎀은 RTC칩 없이도 실시간정보를 수신할 수 있다.Accordingly, the present invention uses a synchronous modem to receive time information in the region in the asynchronous mode, whereby the asynchronous modem can receive real time information without an RTC chip.

이상에서 상세히 설명한 바와 같이 본 발명은 동기식 모뎀을 통해 기지국으로부터 실시간정보를 수신하여 음역지역에서 시간을 가지는방식으로 동기식에서 시간값을 쓸 수 있는 방법을 이용하여 비동기식 모뎀으로 실시간 정보를 전송함으로써, 상기 비동기식 모뎀이 RTC칩 없이 시간정보 수신이 가능하여 사용자가 일일이 시간을 설정해야 하는 번거로움을 해소시키는 효과가 있다.As described in detail above, the present invention receives real time information from a base station through a synchronous modem and transmits real time information to an asynchronous modem by using a method capable of writing a time value in a synchronous manner in a manner having time in a transliteration region. The asynchronous modem can receive the time information without the RTC chip, thereby eliminating the need for the user to set the time manually.
