Abstract

PURPOSE: A method for reducing a battery consumption in a terminal at broadcast service is provided to reduce the battery consumption while the terminal receives broadcast messages, by preparing functions of turn on and off in the terminal and monitoring only typical page slots without monitoring slots for receiving the broadcast messages under a turn-off state of the terminal. CONSTITUTION: If a user sets the terminal not to receive the broadcast messages, only the typical slots can be monitored(100,110). That is, if a setting signal for turning on the broadcast messages is received, a wake-up time of the terminal is calculated in order to broadcast pages and the broadcast messages. If a user sets the terminal to receive the broadcast messages, broadcast slots are monitored separately(100,120). Namely, if a setting signal for turning-off the broadcast messages, the wake-up time thereof is calculated so that the terminal can wake up at typical page slots.

Description

방송서비스에서의 단말기 배터리 소모 감소방법Reduction of terminal battery consumption in broadcasting service

본 발명은 이동통신시스템에 관한 것으로, 특히 방송서비스에서의 단말기 배터리 소모감소방법에 관한 것이다.The present invention relates to a mobile communication system, and more particularly, to a method for reducing terminal battery consumption in a broadcast service.

일반적인 단말기(방송을 수신할 수 없는 단말)는 자신의 페이징(paging)을 위해서 자신의 페이지슬롯(page slot)에서 웨이크업(wake-up)함으로써 여러 가지 CAI(Common Air Interface)메시지를 수신한다. 그 외의 슬롯에서는 웨이크업하지 않음으로써 단말기 배터리 소모를 줄인다.A general terminal (a terminal that cannot receive a broadcast) receives various Common Air Interface (CAI) messages by waking up from its page slot for its paging. In other slots, terminal wake up is reduced by not waking up.

그러나 방송을 수신하는 단말기는 그 방송을 수신하기 위하여 일반적인 단말기가 웨이크업하는 시간이외의 시간에서도 웨이크업해야 하므로 슬립(sleep)하고 있는 단말기를 웨이크업시키기 위해 별도의 동작을 수행한다. 즉 별도의 시간을 계산해두고 그 시간을 시스템과 동기를 맞추면서 웨이크업함으로써 방송메시지를 수신할 수 있다.However, since the terminal receiving the broadcast must wake up at a time other than the time at which the normal terminal wakes up to receive the broadcast, the terminal performs a separate operation to wake up the terminal that is sleeping. In other words, the broadcast message can be received by calculating a separate time and wake-up while synchronizing the time with the system.

따라서 방송을 수신하는 단말기는 별도의 슬롯에서도 웨이크업해야 하므로 기존의 일반적인 단말기에 비해 배터리 소모가 더 발생하게 된다.Therefore, the terminal receiving the broadcast must wake up in a separate slot, resulting in more battery consumption than conventional terminals.

따라서 본 발명의 목적은 방송을 수신하는 단말기에서의 배터리 소모를 감소시키는 방법을 제공하는데 있다.Accordingly, an object of the present invention is to provide a method of reducing battery consumption in a terminal receiving a broadcast.

본 발명의 다른 목적은 방송으로서 소모되는 기본적인 배터리 소모이외의 부분에 관해서는 배터리 소모가 최소화되도록 하는 방법을 제공하는데 있다.Another object of the present invention is to provide a method for minimizing battery consumption in parts other than the basic battery consumption consumed as a broadcast.

상기한 목적에 따라, 본 발명은, 방송서비스에서의 단말기배터리 소모 감소방법에 있어서,In accordance with the above object, the present invention provides a method for reducing terminal battery consumption in a broadcast service.

사용자로부터 방송메시지 온기능 설정이 수신됨에 따라 방송페이지와 방송메시지를 수신키 위해서 웨이크업시간을 계산하는 과정과,Calculating a wake-up time for receiving a broadcast page and a broadcast message as a broadcast message on function setting is received from a user;

상기 사용자로부터 방송메시지 오프기능 설정이 수신됨에 따라 일반적인 페이지슬롯에서만 웨이크업하도록 웨이크업시간을 계산하는 과정으로 이루어짐을 특징으로 한다.When the broadcast message off function setting is received from the user, the wakeup time is calculated to wake up only in a general page slot.

도 1은 단말기 및 시스템의 슬롯동작을 도시한 도면,1 is a view illustrating a slot operation of a terminal and a system;

도 2는 본 발명의 실시예에 따라 단말기에 방송메시지의 온/오프기능이 구현된 구성도,2 is a configuration diagram in which the on / off function of a broadcast message is implemented in a terminal according to an embodiment of the present invention;

도 3은 도 2의 서처 26이 본 발명의 실시예에 따라 수행하는 동작 제어흐름도.3 is an operation control flow chart performed by searcher 26 of FIG. 2 in accordance with an embodiment of the present invention.

이하 본 발명의 바람직한 실시예들을 첨부한 도면을 참조하여 상세히 설명한다.Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

IS-637규격에서는 SMS(Short Message Service)의 일종인 방송서비스(broadcast service)에 대해서 언급하고 있다. 상기 SMS는 GSM(Global System for Mobile communication), CDMA(Code Division Multiple Access), PCS(Personal Communication Service) 방식 등의 이동 무선 단말기 사이에 메시지 통신을 가능하게 하거나, 고정망에서의 메시지를 이동망 내의 처리장치에 일단 축적한 다음 디지털 메시지 형태로 변환하여 이동 단말에 전송하여 주는 서비스를 말한다.The IS-637 standard refers to a broadcast service, which is a kind of short message service (SMS). The SMS enables message communication between mobile wireless terminals such as Global System for Mobile Communication (GSM), Code Division Multiple Access (CDMA), and Personal Communication Service (PCS), or processes messages in a fixed network in a mobile network. A service that accumulates in the device and converts it into a digital message form and transmits it to the mobile terminal.

본 발명의 실시예에서는 IS-637규격의 내용을 기본으로 하고 있으므로 그 문헌을 참조해야할 것이다. 그 문헌에 따르면 방송슬롯(broadcast slot)의 동작방법은 3가지다. Method 1, Method 2, Method 3이 있다.The embodiment of the present invention is based on the contents of the IS-637 standard, and reference should be made to that document. According to the literature, there are three ways of operating a broadcast slot. Method 1, Method 2, Method 3.

각 동작방법에 대해 간단히 설명하면 하기와 같다. Method 1은 시스템이 모든 슬롯에 방송메시지를 보내는 것이고, Method 2는 일반적인 페이지메시지(general page message)가 M( 2i16 , i; 슬롯사이클 인덱스)주기동안 보내어지고, 단말기는 자신의 페이지슬롯에서 방송페이지를 수신하고 t/4mod(M+3)=M에서 방송메시지를 수신하게 되는 방법이다. 그리고 Method 3은 일반적인 페이지메시지를 t/4mod(B+3)=0(B; 2i16 , i; 방송 인덱스(확장시스템 파라메터 메시지))를 수신하게 되고 그후 n×3(m; 페이지번호) 슬롯 떨어진 곳에서 방송메시지를 받게 되는 방법이다. 여기서, t/4는 t/4를 넘지않는 정수를 의미한다. 예를 들면 t/4=5.5이면 t/4=5이다.Brief description of each operation method is as follows. Method 1 is the system sends a broadcast message to all slots. Method 2 is a general page message with M ( 2 i 16 , i; Slot cycle index), and the terminal receives a broadcast page in its page slot and receives a broadcast message at t / 4mod (M + 3) = M. And method 3 is a general page message t / 4mod (B + 3) = 0 (B; 2 i 16 , i; A broadcast index (extension system parameter message)) is received, and then a broadcast message is received at an n × 3 (m; page number) slot. Here, t / 4 means an integer not exceeding t / 4. For example, t / 4 = 5 if t / 4 = 5.5.

본 발명의 실시예에서는 상기 동작방법중 Method 3을 일예로 설명한다. 도 1은 단말기 및 시스템의 슬롯동작을 도시한 도면이다. 도 1에서 단말기는 일반적인 페이지메시지(general page message) 10이나 데이터버스트메시지(data burst message) 12,14,16,18을 받기 위해서 별도의 웨이크업 시간을 계산해야 한다. 그러므로 단말기는 별도의 배터리 소모를 필요로 한다.In the embodiment of the present invention, Method 3 of the operation method is described as an example. 1 illustrates slot operations of a terminal and a system. In FIG. 1, the terminal needs to calculate a separate wakeup time in order to receive a general page message 10 or a data burst message 12, 14, 16, 18. Therefore, the terminal requires a separate battery consumption.

그러나 단말기에서 방송메시지를 받지 않을 경우에는 상기 웨이크업 시간의 계산이 필요 없을 것이다. 그래서 본 발명의 실시예에서는 단말기에 방송메시지의 온/오프기능을 추가한다.However, if the terminal does not receive a broadcast message, the wake-up time calculation may not be necessary. Thus, in the embodiment of the present invention, the on / off function of the broadcast message is added to the terminal.

도 2는 본 발명의 실시예에 따라 단말기에 방송메시지의 온/오프기능이 구현된 구성도이다.2 is a block diagram in which the on / off function of the broadcast message is implemented in the terminal according to an embodiment of the present invention.

시스템에서는 확장 시스템파라메터(방송 인덱스=1∼7)를 보내주고 계산된 시간에서 일반적인 페이지메시지와 데이터버스트메시지를 도 2의 단말기로 전송해준다. 도 2를 참조하면, 단말기의 CAI(Common Air Interface) 20은 시스템에서 일반적인 페이지메시지와 데이터버스메시지를 수신하면 이를 분석하여 MC(Message Classification part) 22로 전달해준다. MC 22는 메시지를 분류하여 UI(User Interface) 24로 보내주고, 슬립하게될 조건을 체크해서 그에 대응된 명령을 서처(searcher) 26으로 넘겨준다. UI 24는 사용자에 의해서 방송메시지의 온/오프 설정을 수신하게 되며 이를 서처 26으로 보내준다.The system sends an extended system parameter (broadcast index = 1-7) and transmits a general page message and data burst message to the terminal of FIG. 2 at the calculated time. Referring to FIG. 2, when the common air interface (CAI) 20 of the terminal receives a general page message and a data bus message from the system, the CAI 20 analyzes it and delivers the same to the MC (Message Classification part) 22. The MC 22 categorizes the message and sends the message to the user interface (UI) 24. The MC 22 checks the condition to sleep and passes the corresponding command to the searcher 26. The UI 24 receives the on / off setting of the broadcast message by the user and sends it to the search 26.

도 2의 서처(searcher) 26은 본 발명의 실시예에 따라 도 3과 같은 동작 제어를 수행한다. 단말기가 방송메시지를 받지 않을 것이라고 사용자에 의해 선택되어지면 일반적인 페이지슬롯만을 모니터링한다(100단계, 110단계). 즉, UI 24로부터 방송메시지 온기능 설정이 수신되면, 방송페이지와 방송메시지를 수신키 위해서 웨이크업시간을 계산한다. 그렇지만 단말기가 방송메시지를 받을 것이라고 사용자에 의해 선택되어지면 방송슬롯을 별도로 모니터링한다(100단계, 120단계). 즉, UI 24로부터 방송메시지 오프기능 설정이 수신되면, 일반적인 페이지슬롯에서만 웨이크업하도록 시간계산을 한다.Searcher 26 of FIG. 2 performs the operation control as shown in FIG. 3 according to an embodiment of the present invention. If the terminal is selected by the user not to receive the broadcast message, only general page slots are monitored (steps 100 and 110). That is, when the broadcast message on function setting is received from the UI 24, the wakeup time is calculated to receive the broadcast page and the broadcast message. However, if the terminal is selected by the user to receive a broadcast message, the broadcast slot is monitored separately (steps 100 and 120). That is, when the broadcast message off function setting is received from the UI 24, time calculation is performed to wake up only in a general page slot.

상술한 본 발명의 설명에서는 구체적인 실시예에 관해 설명하였으나, 여러가지 변형이 본 발명의 범위에서 벗어나지 않고 실시할 수 있다. 따라서 본 발명의 범위는 설명된 실시예에 의하여 정할 것이 아니고 특허청구범위와 특허청구범위의 균등한 것에 의해 정해 져야 한다.In the above description of the present invention, specific embodiments have been described, but various modifications can be made without departing from the scope of the present invention. Therefore, the scope of the present invention should not be defined by the described embodiments, but should be defined by the equivalent of claims and claims.

상술한 바와 같이 본 발명은 방송수신을 할 수 있도록 프로그램되어 있다면 어떤 상태에서든 배터리 소모가 일반단말기에 비해서 많아지지만, 온/오프기능을 두고 또한 오프상태에서는 방송메시지 수신을 위한 별도의 슬롯 모니터링을 하지 않고 일반적인 페이지슬롯만을 모니터링하게 되므로 단말기 배터리 소모를 절감시킨다.As described above, the present invention increases the battery consumption in any state as long as it is programmed to receive broadcasts, but has an on / off function and does not monitor a separate slot for receiving a broadcast message in the off state. It only monitors general page slots and saves battery power.
