Abstract

PURPOSE: A method for transmitting a commercial message in a mobile communication terminal is provided to transmit a commercial CB(Cell Broadcast) message while a user is on the line in case of using a DTX(Discontinuous Transmission) mode of a GSM(Global System for Mobile communication) to transmit the message irrespective of the state of the mobile communication terminal. CONSTITUTION: A base station judges whether a transmission voice is detected. If the transmission voice is detected, the base station composes a general voice frame and composes a traffic channel. If the transmission voice is not detected, the base station judges whether a CB message is turned on. If the CB message is turned on, the base station composes a DCBD(Dedicated Cell-Broadcast Descriptor) frame, composes the traffic channel, and transmits the DCBD frame. If the CB message is turned off, the base station composes an SID(Silence Descriptor) frame and transmits the SID frame.

Description

이동통신 단말기의 상업성 메시지 전송방법{METHOD FOR CELL BROADCAST MESSAGE TRANSMISSION OF MOBILE COMMUNICATION TERMINAL}METHOOD FOR CELL BROADCAST MESSAGE TRANSMISSION OF MOBILE COMMUNICATION TERMINAL}

본 발명은 이동통신 단말기의 상업성 메시지 전송방법에 관한 것으로, 특히 GSM(Global System for Mobile communication)의 DTX(Discontinuous Transmission)모드를 사용할 경우, 단말기의 상태에 관계없이 메시지를 전송하기 위해 통화중에 상업성 CB(Cell Broadcast) 메시지를 전송할 수 있도록 한 이동통신 단말기의 상업성 메시지 전송방법에 관한 것이다.The present invention relates to a commercial message transmission method of a mobile communication terminal, and in particular, when using the Discontinuous Transmission (DTX) mode of Global System for Mobile Communication (GSM), commercial CB during a call to transmit a message regardless of the state of the terminal (Cell Broadcast) The present invention relates to a commercial message transmission method of a mobile communication terminal capable of transmitting a message.

일반적으로, DTX모드는 가변적인 비트 속도(bit rate)에 해당하는 것으로, 필요하지 않을때 고주파신호의 전송을 금지시킴으로써, 간섭 레벨를 감소되어 시스템의 효율을 높이는데 목적이 있다.In general, the DTX mode corresponds to a variable bit rate, and the purpose of the present invention is to increase the efficiency of the system by reducing the interference level by prohibiting the transmission of a high frequency signal when it is not needed.

이러한 종래의 SID(Silence Descriptor) 프레임을 이용한 데이터 전송은 도 1에 도시된 바와 같다.Data transmission using the conventional Silence Descriptor (SID) frame is shown in FIG. 1.

DTX모드에서 사용자가 말하고 있을때 13Kbit/s에서 사용자의 말을 인코드하고, 그렇지 않을경우 약 500bit/s로 인코드한다.In DTX mode, when you are speaking, it encodes your words at 13Kbit / s, otherwise it is about 500bit / s.

이런 느린 속도(rate)는 통화시 통화 청취자 접속이 끊어짐을 인식하지 못하도록 재생되는 백그라운드 노이즈(Background Noise=Comfort Noise; 듣기에 편안한 소리)를 인코드하기에 충분한다.This slow rate is sufficient to encode background noise (Background Noise = Comfort Noise), which is reproduced in order not to recognize the disconnection of the call listener during a call.

GSM의 DTX를 사용할 경우 실제통화는 50%이하이고, 나머지는 사용자의 음성이 없는 노이즈(Back Ground Noise=Comfort Noise)가 발생하도록 스펙상 설계가 되어 GSM망에서 CB(Cell Broadcast)채널을 통해서 상업성 SMS(Short Messaging Service) 정보를 알릴 수 있다.When using GSM DTX, the actual call is less than 50%, and the rest is designed to produce noise without user's voice (Back Ground Noise = Comfort Noise), so it is commercially available through CB (Cell Broadcast) channel in GSM network. It can inform Short Messaging Service (SMS) information.

그러나, 종래의 GSM 통화모드에서 통화 이외에 SMS 전송시, 실제 통화중에 관계없이 메시지를 전송될 경우, 전송량이 많게 되면 통화에 지장을 줄 수 있을뿐만 아니라, CB채널은 유휴상태에서 단말기의 상태에 관계없이 전송되어, 전송당시 이동통신 단말기가 꺼져 있거나, 음영지역에 위치한 경우 CB메시지를 전달할 수 없는 문제점이 있었다.However, in case of transmitting SMS in addition to the call in the conventional GSM call mode, if the message is transmitted regardless of the actual call, the large amount of transmission may interfere with the call, and the CB channel is related to the state of the terminal in the idle state. There is a problem that the CB message can not be delivered when the mobile communication terminal is turned off or located in the shadowed area at the time of transmission.

따라서, 본 발명은 상기와 같은 문제점을 해결하기 위하여 창안한 것으로, DCB(Dedicated Cell Broadcast)를 이용하면 현재 통화 채널이므로 반드시 CB메시지가 사용자에게 전송될 수 있는 장점이 있고, 기존의 자원에서 또 하나의 채널을 구성하여 무선 자원을 늘릴 수 있도록 한 이동통신 단말기의 상업성 메시지 전송방법을 제공함에 그 목적이 있다.Accordingly, the present invention has been made to solve the above-mentioned problems, the use of DCB (Dedicated Cell Broadcast) has the advantage that the CB message can be transmitted to the user because it is a current call channel, another one from the existing resources An object of the present invention is to provide a commercial message transmission method of a mobile communication terminal that can increase a radio resource by configuring a channel.

상기와 같은 목적을 달성하기 위한 본 발명은, 기지국과 단말기간의 상호 데이터를 교환함에 있어서, 송신측인 기지국은 송신 음성을 검출하였는가를 판단하는 단계와; 상기 송신 음성이 검출되면 일반 음성프레임을 구성하여 통화채널을 구성하는 단계와; 상기 판단결과, 송신 음성이 검출되지 않으면 CB(Cell Broadcast)메시지가 온되었는지를 판단하여 CB메시지가 온되면 DCBD(Dedicate Cell-Broadcast Descriptor)프레임을 구성하여 통화채널을 구성하여 송신하는 단계와; 상기 CB메시지가 온되지 않으면 SID(Silence Descriptor)프레임을 구성하여 통화채널을 구성하여 송신하는 단계로 이루어진 것을 특징으로 한다.The present invention for achieving the above object comprises the steps of, in the exchange of data between the base station and the terminal, the base station on the transmission side determines whether or not the transmission voice; Configuring a communication channel by configuring a general voice frame when the transmission voice is detected; Determining that a CB (Cell Broadcast) message is turned on if no transmission voice is detected, and if a CB message is turned on, constructing a DCBD (Dedicate Cell-Broadcast Descriptor) frame to configure and transmit a call channel; If the CB message is not turned on, it comprises a step of configuring a transmission channel by constructing a Silence Descriptor (SID) frame.

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 2는 본 발명 DCBD(Dedicate Cell-Broadcast Descriptor)프레임을 이용한 데이터 전송방법을 보인 흐름도로서, 이에 도시된 바와 같이 기지국과 단말기간의 상호 데이터를 교환함에 있어서, 송신측인 기지국은 송신 음성을 검출하였는가를 판단하는 단계와; 상기 송신 음성이 검출되면 일반 음성프레임을 구성하여 통화채널을 구성하는 단계와; 상기 판단결과, 송신 음성이 검출되지 않으면 CB(Cell Broadcast)메시지가 온되었는지를 판단하여 CB메시지가 온되면 DCBD(Dedicate Cell-Broadcast Descriptor)프레임을 구성하여 통화채널을 구성하여 송신하는 단계와; 상기 CB메시지가 온되지 않으면 SID(Silence Descriptor)프레임을 구성하여 송신하는 단계로 이루어진 것으로, 이와 같이 구성된 본 발명의 동작을 설명하면 다음과 같다.2 is a flowchart illustrating a data transmission method using a Dedicated Cell-Broadcast Descriptor (DCBD) frame according to the present invention. As shown in FIG. 2, in the exchange of mutual data between a base station and a terminal, has the base station on the transmitting side detected a transmission voice? Determining; Configuring a communication channel by configuring a general voice frame when the transmission voice is detected; Determining that a CB (Cell Broadcast) message is turned on if no transmission voice is detected, and if a CB message is turned on, constructing a DCBD (Dedicate Cell-Broadcast Descriptor) frame to configure and transmit a call channel; When the CB message is not turned on, a configuration of a Silence Descriptor (SID) frame is performed and transmitted. The operation of the present invention configured as described above will be described below.

본 발명은 통화채널을 이용하여 CB(Cell Broadcast)채널을 통해서만 상업성 정보를 알릴 수 있었던 것을 통화시 DTX(Discontinuous Transmission)모드에서 사용자의 음성이 없는 백그라운드 노이즈 발생기간을 이용하여 또다른 CB채널을 구성하여 상업성 정보를 전송한다.The present invention configures another CB channel using a background noise generation period in which the user's voice is absent in the DTX mode in the case that the commercial information can be announced only through the CB (Cell Broadcast) channel using the call channel. To transmit commercial information.

먼저, 기지국은 단말기와 단말기간의 통화상태를 계속해서 체크하여 송신 음성데이터를 검출한다.First, the base station continuously checks the call state between the terminal and the terminal to detect the transmitted voice data.

이때, 상기 송신 음성데이터가 검출되면 단말기와 단말기간의 통화상태의 통화프레임을 구성하여 호(Traffic)채널을 구성한다.In this case, when the transmission voice data is detected, a call channel is configured by configuring a call frame in a call state between the terminal and the terminal.

그러나, 단말기와 단말기간의 통화상태시 송신 음성데이터를 검출하지 못했을 경우, DCB(Dedicate Cell-Broadcast) 채널 감지를 위한 DCBD(Dedicate Cell-Broadcast Descriptor) 프레임을 추가하여 CB메시지가 온되었는지 판단한다.However, when the transmission voice data is not detected in the call state between the terminal and the terminal, it determines whether the CB message is on by adding a Dedicated Cell-Broadcast Descriptor (DCBD) frame for detecting a Dedicated Cell-Broadcast (DCB) channel.

상기 판단결과, CB메시지가 오프상태면 SID프레임을 구성하여 호(Traffic)채널을 구성하고, CB메시지가 온상태면 DCBD프레임을 구성하여 호채널을 구성한다.As a result of the determination, when the CB message is in the off state, a SID frame is formed to form a call channel. When the CB message is in the on state, a DCBD frame is configured to form a call channel.

이와 같은 DCBD 프레임을 이용한 데이터 전송은 도 3에 도시된 바와 같다.Data transmission using such a DCBD frame is illustrated in FIG. 3.

즉, 현재 DTX(Discontinuous Transmission)모드는 SID(Silence Descriptor) 프레임을 이용하여 음성이 없을 경우 SID를 전송하고 백그라운드 노이즈(Background Noise=Comfort Noise)를 발생시키며 SID 프레임외 DCB채널 감지를 위한 DCBD 프레임을 추가하여 SMS와 동일한 FACCH채널을 이용하여 SMS형태로 DCB를 전송한다.That is, DTX (Discontinuous Transmission) mode uses SID (Silence Descriptor) frame to transmit SID when there is no voice, generates background noise (Background Noise = Comfort Noise), and detects DCBD frame for detecting DCB channel other than SID frame. In addition, DCB is transmitted in the form of SMS using the same FACCH channel as SMS.

여기서, DCBD는 기존의 480ms마다 SID frame과 동일한 주기를 사용하고, 단말기의 보코더(Vo-coder)쪽은 SID 프레임과 DCBD 프레임은 동일하게 백그라운드 노이즈를 발생시킨다.Here, the DCBD uses the same period as the SID frame every 480ms, and the background code of the SID frame and the DCBD frame on the Vo-coder side of the terminal are the same.

상기한 바와 같은 과정에 의해 수신측인 단말기는 도 4에 도시된 바와 같이 SID프레임이 검출되었는가를 판단한다.By the above process, the receiving terminal determines whether the SID frame is detected as shown in FIG.

상기 SID 프레임이 검출되면 백그라운드 노이즈가 발생하고, 상기 SID 프레임이 검출되지 않으면 DCBD 프레임이 검출되었는지 판단한다.If the SID frame is detected, background noise is generated. If the SID frame is not detected, it is determined whether a DCBD frame is detected.

이에, 상기 DCBD 프레임 검출되지 않은경우, 상대방의 음성을 디코딩한다.Therefore, when the DCBD frame is not detected, the other party's voice is decoded.

그러나, 상기 판단결과, DCBD 프레임이 검출되면 DCB로 데이터를 수신한다.However, if the DCBD frame is detected as a result of the determination, data is received by the DCB.

상기 DCB로 받은 데이터는 사용자의 설정에 의해 단말기의 통화중이나 혹은 종료후 CB메시지나 SMS메시지의 프로토콜을 통해 단말기의 디스플레이창에 디스플레이된다.The data received by the DCB is displayed on the display window of the terminal through the protocol of the CB message or SMS message during or after the call of the terminal by the user's setting.

이상에서 상세히 설명한 바와 같이 본 발명은 이동통신 단말기의 상태가 통화상태시, 상업성 메시지를 DCB(Dedicated Cell Broadcast)를 이용하면 현재 통화 채널이므로 반드시 사용자에게 상업성 메시지를 전송할 수 있고, 기존의 자원에서 또 하나의 채널을 구성하여 무선 자원을 늘릴 수 있는 효과가 있다.As described in detail above, when the state of the mobile communication terminal is in a call state, the commercial message is a current call channel using DCB (Dedicated Cell Broadcast). There is an effect that can increase the radio resources by configuring one channel.
