3 : IRDA 송신모듈 4 : IRDA3: IRDA transmitting module 4: IRDA
5 : RF 송신모듈5: RF transmission module
이하, 첨부된 도면을 참조하여 본 발명을 상세히 설명하면 다음과 같다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.
현재 이동단말기의 경우 무선 결재 서비스(예를 들어, M커머스 또는 K머스) 기능을 가지고 있는데, 이러한 서비스를 위해서 이동단말기에는 IRDA 또는 근거리 RF 루프 안테나가 내장되어 있다.Currently, the mobile terminal has a wireless payment service (for example, M-commerce or K-commerce). For this service, the mobile terminal includes an IRDA or a near-field RF loop antenna.
본 발명은 이러한 IRDA 또는 근거리 RF 루프 안테나가 내장된 이동단말기를이용하여, 이동단말기와 외장형 키보드간의 통신을 종래의 유선 방식이 아닌 무선 결재용 인터페이스를 통해 수행하고자 하는 것이다.The present invention intends to perform communication between a mobile terminal and an external keyboard using a wireless payment interface rather than a conventional wired method by using a mobile terminal having such an IRDA or a short-range RF loop antenna.
도 1은 본 발명에 의한 제 1실시예로서, 이동단말기와 외장형 키보드가 IRDA 방식에 의해 통신하는 실시예를 나타낸다.1 illustrates an embodiment in which a mobile terminal and an external keyboard communicate with each other by IRDA as a first embodiment according to the present invention.
또한, 도 2는 본 발명에 의한 제 2실시예로서, 이동단말기와 외장형 키보드가 근거리 RF 방식에 의해 통신하는 실시예를 나타낸다.2 shows an embodiment in which a mobile terminal and an external keyboard communicate by a short range RF method.
도 1 및 도 2에 도시된 바와 같이, 외장형 키보드(1)는 키 데이터를 이동단말기(2)에 무선으로 송신하기 위한 송신모듈로서 IRDA 송신모듈(3) 또는 RF 송신모듈(4)을 포함한다.As shown in FIGS. 1 and 2, the external keyboard 1 includes an IRDA transmission module 3 or an RF transmission module 4 as a transmission module for wirelessly transmitting key data to the mobile terminal 2. .
이동단말기(2)는 IRDA 또는 근거리 RF 방식으로 무선 송신된 키 데이터를 수신하기 위한 수신부로서 IRDA(4) 또는 근거리 RF 안테나(도시하지 않음)와, 수신된 키 데이터를 처리하여 키보드에서 입력한 문자를 인식하기 위한 프로세서부(도시하지 않음)를 포함한다.The mobile terminal 2 is a receiver for receiving key data wirelessly transmitted by IRDA or near field RF. An IRDA 4 or near field RF antenna (not shown) and characters received from the keyboard by processing the received key data It includes a processor unit (not shown) for recognizing.
프로세서부는 이동단말기의 전체적인 동작을 제어하는 부분으로서, 예를 들어 MSM 등이 있다.The processor unit is a part for controlling the overall operation of the mobile terminal, for example MSM.
외장형 키보드(1)에서 문자를 입력하면, 키 데이터가 송신모듈(3, 5)을 통해 이동단말기의 수신부(적외선 통신의 경우 IRDA(4), RF 통신인 경우 RF 안테나)로 수신된다.When a character is input from the external keyboard 1, the key data is received by the receiving unit (IRDA 4 in the case of infrared communication, RF antenna in the case of RF communication) of the mobile terminal through the transmission module (3, 5).
수신부에 수신된 키 데이터는 프로세서부에 입력된 후 소정의 처리를 거쳐 이동단말기의 화면에 표시된다.The key data received in the receiver is input to the processor and then displayed on the screen of the mobile terminal through a predetermined process.
도 3을 참조하여 이동단말기에서 수신한 무선 데이터를 처리하는 과정을 설명한다.A process of processing wireless data received by a mobile terminal will be described with reference to FIG. 3.
우선, 이동단말기가 IRDA 또는 RF 방식으로 무선 데이터를 수신하면, 이 무선 데이터가 키 데이터인지 아닌지를 판단한다.First, when the mobile terminal receives radio data by IRDA or RF, it is determined whether the radio data is key data.
만약, 수신된 무선 데이터가 키보드에서 송신된 키 데이터이면 키보드를 인식하고, 키 데이터가 아니면 다른 동작을 수행한다. 예를 들어, 수신된 무선데이터가 결재 서비스를 위한 무선 데이터인 경우에는 종래의 결재 처리를 수행한다.If the received wireless data is key data transmitted from the keyboard, the keyboard is recognized. If the received wireless data is not key data, other operations are performed. For example, when the received wireless data is wireless data for a payment service, a conventional payment process is performed.
프로세서부가 키보드를 인식하면 수신부를 통해 키 데이터를 입력받아 처리함으로써 키보드에서 입력된 문자를 인식한다. 인식된 문자는 이동단말기의 화면을 통해 사용자에게 표시된다.When the processor recognizes the keyboard, the processor receives the key data through the receiver and processes the key data to recognize the characters input from the keyboard. The recognized character is displayed to the user through the screen of the mobile terminal.
외장형 키보드로부터 수신한 키 데이터의 처리는 IRDA 또는 근거리 RF 루프 안테나를 내장한 이동단말기라면 하드웨어의 변경없이 내부의 소프트웨어를 추가하는 것으로 가능하다.The processing of key data received from an external keyboard can be performed by adding internal software without changing hardware in a mobile terminal having an IRDA or a near-field RF loop antenna.
또한, 외장형 키보드에 있는 IRDA 또는 근거리 RF 송신모듈의 하드웨어 규격과 IRDA 또는 근거리 RF 루프 안테나를 사용하는 통신의 소프트웨어의 규격은 기존의 표준 규격을 적용하기 때문에 쉽게 구현할 수 있다.In addition, the hardware specification of the IRDA or short-range RF transmission module in the external keyboard and the software specification of the communication using the IRDA or short-range RF loop antenna can be easily implemented because the existing standard specification is applied.
상기와 같이 본 발명은 무선 결재 서비스가 가능한 이동단말기와 무선 송신모듈을 가진 외장형 키보드를 이용하여, 외장형 키보드를 통한 이동단말기로의 문자 입력시 사용자의 편의를 증대시키는 효과가 있다.As described above, the present invention uses an external keyboard having a mobile terminal and a wireless transmission module capable of wireless payment service, thereby increasing the user's convenience when inputting text to the mobile terminal through the external keyboard.
또한, 무선 결재 서비스가 가능한 이동단말기라면 하드웨어의 수정없이 소프트웨어의 추가만으로 쉽게 사용이 가능하고, 외장형 키보드가 다양한 이동단말기와 호환가능한 효과가 있다.In addition, a mobile terminal capable of wireless payment service can be easily used by adding software without modification of hardware, and an external keyboard has an effect compatible with various mobile terminals.
