이동통신 단말기의 절전 방법{POWER SAVING METHOD OF MOBILE TELECOMMUNICATION TERMINAL EQUIPMENT}Power saving method of mobile terminal {POWER SAVING METHOD OF MOBILE TELECOMMUNICATION TERMINAL EQUIPMENT}

본 발명은 1X EV-DO를 지원하는 단말기의 절전기술에 관한 것으로, 특히 EV-DO 망을 사용하지 않을 때 단말기내의 EV-DO 관련 소자의 전원공급을 차단하여 불필요하게 전력이 소모되는 것을 방지할 수 있도록 한 이동통신 단말기의 절전 방법에 관한 것이다.The present invention relates to a power saving technology of a terminal supporting 1X EV-DO. In particular, when the EV-DO network is not used, power supply of an EV-DO related device in the terminal is cut off to prevent unnecessary power consumption. The present invention relates to a power saving method of a mobile communication terminal.

EV-DO 단말기는 1X와 EV-DO 망을 동시에 지원할 수 있다. 1X망은 IS-2000을 따르며 음성과 데이터 서비스 모두 가능하고, EV-DO망은 IS-856을 따르며 패킷 데이터 서비스만 가능하다. 상기 EV-DO 단말기는 1X와 EV-DO 망을 모두 지원해야 하기 때문에 대기상태에서 1X 망과 EV-DO 망의 페이징(paging)을 순차적으로 체크하여 서비스를 제공한다.EV-DO terminal can support 1X and EV-DO network at the same time. The 1X network follows IS-2000, and both voice and data services are available. The EV-DO network follows IS-856 and only packet data services. Since the EV-DO terminal must support both 1X and EV-DO networks, the EV-DO terminal sequentially checks paging of the 1X network and the EV-DO network to provide a service.

그런데, 종래의 이동통신 단말기에 있어서는 EV-DO 서비스가 필요하지 않은 대기상태에서도 EV-DO 관련 소자에 전원이 계속 공급되므로 불필요하게 배터리 전원이 소모되는 결함이 있었다. 더욱이 EV-DO 망이 구축되어 있지 않은 지역에서도 EV-DO 관련 소자에 전원이 계속 공급되어 배터리 전원이 낭비되는 결함이 있었다.However, in the conventional mobile communication terminal, since power is continuously supplied to the EV-DO-related device even in the standby state where the EV-DO service is not required, there is a defect that the battery power is unnecessarily consumed. Moreover, even in areas where the EV-DO network was not established, there was a defect in that battery power was wasted because the EV-DO-related devices were continuously supplied with power.

따라서, 본 발명의 목적은 EV-DO 서비스가 필요하지 않은 대기상태에 있거나 또는 EV-DO 망이 구축되어 있지 않은 지역에 위치하게 될 때, EV-DO 관련 소자의 전원공급을 차단하는 이동통신 단말기의 절전 방법을 제공함에 있다.Accordingly, an object of the present invention is to provide a mobile communication terminal that cuts off the power supply of an EV-DO-related device when it is located in a standby state where an EV-DO service is not required or in an area where an EV-DO network is not established. To provide a power saving method.

SA1-SA7 : 제1-7단계SA1-SA7: Steps 1-7

본 발명에 의한 이동통신 단말기의 절전 방법은, 송신모드 초기 전원 인가 시 1X를 활성화시키고, EV-DO를 비활성화시켜 대기상태로 천이한 후, 사용자가 호를 시도하면 음성통화 모드이거나 시스템의 EV-DO 망이 지원되지 않을 때 1X 망에서 서비스를 제공하는 제1과정과; 상기 시도한 호가 데이터 호인 경우 상기 시스템의 EV-DO 망이 지원되면 EV-DO를 활성화시켜 서비스를 제공하고 호 종료 후 EV-DO를 비활성화시키고 대기 상태로 천이하는 제2과정과; 수신모드 초기 전원 인가 시 1X를 활성화시키고, EV-DO를 비활성화시켜 대기상태로 천이한 후 주기적으로 인컴잉 콜과 오버헤드 메시지를 체크하여 인컴잉 콜이거나 시스템의 EV-DO 망 페이지가도착하지 않으면 호, 메시지 처리 후 대기 상태로 천이하는 제3과정과; 상기 페이지가 도착하면 EV-DO를 활성화시키고 EV-DO 망에서 인컴잉 콜을 처리한 다음 EV-DO를 비활성화시키고 대기상태로 천이하는 제4과정으로 이루어지는 것으로, 이와 같은 본 발명의 절전처리 과정을 첨부한 도 1 및 도 2를 참조하여 상세히 설명하면 다음과 같다.In the power saving method of the mobile communication terminal according to the present invention, when the initial power is applied to the transmission mode, 1X is activated, the EV-DO is deactivated, the system is transferred to the standby state, and the user attempts to make a call. Providing a service in a 1X network when the DO network is not supported; If the attempted call is a data call, if the EV-DO network of the system is supported, a second process of activating the EV-DO to provide a service, deactivating the EV-DO after the call is terminated, and transitioning to a standby state; Receive Mode Activate 1X at initial power-up, disable EV-DO, transition to standby state, and periodically check incoming calls and overhead messages to see if incoming calls or the system's EV-DO network page do not arrive. Transitioning to a standby state after processing a call or a message; When the page arrives, a fourth process of activating the EV-DO, processing the incoming call in the EV-DO network, deactivating the EV-DO, and transitioning to the standby state is performed. When described in detail with reference to the accompanying Figures 1 and 2 as follows.

1X EV-DO를 지원하는 단말기의 송수신 시 EV-DO 망의 사용 여부를 체크하기 위해 1X 망 시스템 정보를 수정하거나 추가할 필요가 있다. 데이터 호 송신 시에는 EV-DO 망의 존재 여부를 나타내는 시스템 정보가 필요하고, EV-DO 망의 페이징이 발생할 경우에는 EV-DO 페이지의 도착여부를 나타내는 시스템 정보가 필요하다. 그리고, EV-DO 단말기는 1X 망 시스템과 약속된 오버헤드 메시지를 이용하여 시스템 정보를 얻을 수 있어야 한다.In order to check whether the EV-DO network is used to transmit or receive a terminal supporting 1X EV-DO, it is necessary to modify or add 1X network system information. When transmitting a data call, system information indicating whether an EV-DO network is present is required. When paging of an EV-DO network is required, system information indicating whether an EV-DO page arrives is required. In addition, the EV-DO terminal should be able to obtain system information by using the overhead message promised with the 1X network system.

본 발명에 의한 송신모드에서의 배터리전원 절전방법을 도 1을 참조하여 설명하면 다음과 같다.The battery power saving method in the transmission mode according to the present invention will be described with reference to FIG.

EV-DO 단말기의 초기 전원 인가 시 1X를 활성화시키고, EV-DO를 비활성화시켜 대기상태로 천이한다.(SA1)When the EV-DO terminal is initially powered on, it activates 1X and deactivates EV-DO to transition to standby. (SA1)

대기 상태에서 사용자가 호(call)를 시도한 경우, 음성통화나 EVDO_EXIST(시스템의 EV-DO 망 지원여부를 나타내는 플래그, 오버헤드 메시지에서 추가해야 함)가 "폴스"(false)이면 1X 망에서 서비스를 제공한다.(SA2-SA4)If a user attempts to make a call while in standby, if the voice call or EVDO_EXIST (a flag indicating whether the system supports the EV-DO network and should be added in the overhead message) is "false", the service is performed on the 1X network. (SA2-SA4)

상기 시도한 호가 데이터 호인 경우, 상기 EVDO_EXIST가 "트루"(true)이면 EV-DO를 활성화시켜 서비스를 제공하고, 호 종료 후 EV-DO를 비활성화시키고 대기상태로 천이한다.(SA5-SA7)If the attempted call is a data call, if the EVDO_EXIST is "true", the EV-DO is activated to provide a service, and after the call ends, the EV-DO is deactivated and transitions to the standby state. (SA5-SA7)

한편, 본 발명에 의한 수신모드에서의 배터리전원 절전방법을 도 2를 참조하여 설명하면 다음과 같다.Meanwhile, a battery power saving method in the reception mode according to the present invention will be described with reference to FIG. 2.

EV-DO 단말기의 초기 전원 인가 시 1X를 활성화시키고, EV-DO를 비활성화시켜 대기상태로 천이한다.(SB1)When the initial power is applied to the EV-DO terminal, 1X is activated, and the EV-DO is deactivated to transition to the standby state (SB1).

상기 EV-DO 단말기는 주기적으로 인컴잉 콜(incomming call)과 오버헤드 메시지를 체크하여 인컴잉 콜이거나 오버헤드 메시지의 EVDO_PAGE_EXIST(시스템의 EV-DO 망 페이지 도착을 나타내는 플래그, 오버헤드 메시지에서 추가해야 함)가 "폴스"이면 호, 메시지 처리 후 대기 상태로 천이한다.(SB2-SB6)The EV-DO terminal periodically checks an incoming call and an overhead message and adds the incoming call or the EVDO_PAGE_EXIST (flag indicating the arrival of the EV-DO network page of the system, an overhead message) of the overhead message. Is set to "fall", the call goes to the standby state after processing the message. (SB2-SB6)

그러나, 오버헤드 메시지의 EVDO_PAGE_EXIST가 "트루"이면 EV-DO를 활성화시키고 EV-DO 망에서 인컴잉 콜을 처리한 다음 EV-DO를 비활성화시키고 대기상태로 천이한다.(SB7)However, if the EVDO_PAGE_EXIST of the overhead message is "true", the EV-DO is activated, the incoming call is processed in the EV-DO network, the EV-DO is deactivated, and the standby state is transferred (SB7).

이상에서 상세히 설명한 바와 같이 본 발명은 EV-DO 서비스가 필요하지 않은 대기상태에 있거나 또는 EV-DO 망이 구축되어 있지 않은 지역에 위치하게 될 때, EV-DO 관련 소자의 전원공급이 자동적으로 차단되게 함으로써, 단말기의 배터리 전원이 불필요하게 소모되는 것을 방지할 수 있는 효과가 있다.As described in detail above, the present invention automatically cuts off the power supply of an EV-DO-related device when it is in a standby state where no EV-DO service is required or when it is located in an area where an EV-DO network is not established. By doing so, there is an effect that can be prevented from unnecessary consumption of the battery power of the terminal.
