Description

휴대폰 인터페이스장치{Apparatus for interfacing between mobile phone}Mobile phone interface device {Apparatus for interfacing between mobile phone}

본 발명은 휴대폰 인터페이스장치에 관한 것으로서, 좀 더 상세하게는 호스트 휴대폰과 외부 휴대폰를 연결하여 상호간의 통신을 지원하는 휴대폰 인터페이스장치에 관한 것이다.The present invention relates to a mobile phone interface device, and more particularly, to a mobile phone interface device that supports communication between each other by connecting a host mobile phone and an external mobile phone.

최근들어 휴대폰은 그 성능이 향상되면서 전화수단을 넘어 다양한 기능을 가진 기기로 변모해가고 있다.In recent years, as the performance of mobile phones has improved, the mobile phone has been transformed into a device with various functions.

예를 들어, 휴대폰은 무선인터넷을 제공하는 정보통신수단으로 활용되고 있다. 따라서 휴대폰 사용자들은 언제 어디서나 무선으로 인터넷에 접속하여 원하는 정보를 얻을 수 있다.For example, a mobile phone is used as an information communication means for providing a wireless Internet. Therefore, mobile phone users can access the Internet wirelessly anytime, anywhere to get the information they want.

또한, 휴대폰은 게임을 제공하는 통신수단으로 사용되고 있다. 특히 최근에는 컬러휴대폰의 급속한 보급에 따라 게임이 주요 콘텐츠로 각광받고 있다. 현재 휴대폰은 혼자서 즐길 수 있는 게임과 여러명이 협력 또는 경쟁하면서 즐기는 게임을 모두 지원하고 있다.In addition, the mobile phone is used as a communication means for providing a game. In particular, with the rapid spread of color mobile phones, games have been in the spotlight. Currently, mobile phones support both games that can be played alone and games that are played by several people in cooperation or competition.

그러나, 아직까지 휴대폰에서 무선 네트워크를 통한 게임방식은 무선 네트워크의 이용 요금이 비싸고 그 속도가 충분히 빠르지 못한 단점이 있다.However, the game method through the wireless network in the mobile phone has a disadvantage that the use of the wireless network is expensive and the speed is not fast enough.

그래서 본 발명자는 2∼3명이 휴대폰을 케이블로 연결하여 게임을 하는 새로운 게임형태를 생각하게 되었다. 휴대폰과 휴대폰을 케이블로 연결하는 게임방식은 직렬통신을 지원하므로 게임의 속도가 빠른 장점이 있다.Thus, the present inventors came to think of a new game type in which two or three people play a game by connecting a mobile phone with a cable. The game method of connecting the mobile phone with the mobile phone has the advantage of speeding up the game because it supports serial communication.

그러나 기존의 휴대폰 인터페이스는 18pin 또는 24pin으로 제작되어 있으므로 사용자는 복수개의 케이블을 항상 휴대해야 하는 큰 불편이 있다. 나아가 휴대폰을 연결하는 케이블은 최소 6개의 신호선 예를 들어, 송신(Tx) 신호선, 수신(Rx) 신호선, 그라운드(GND) 신호선 송신요구(RTS) 신호선 송신가능(CTS) 신호선 및 신호데이터단말준비완료(DTR) 신호선을 필요로 하므로 각각의 케이블의 크기와 비용이 커지는 단점이 있다.However, since the existing mobile phone interface is made of 18pin or 24pin, the user has a great inconvenience of always carrying a plurality of cables. Further, the cable connecting the mobile phone has at least six signal lines, for example, a transmit (Tx) signal line, a receive (Rx) signal line, a ground (GND) signal line, a transmit request (RTS) signal line, a transmittable (CTS) signal line, and a signal data terminal ready. Since a (DTR) signal line is required, the size and cost of each cable are increased.

또한, 현재 게임을 지원하는 휴대폰은 브루(BREW) 플랫폼(platform)을 내장한 휴대폰(016, 018)과 지.브이.엠(GVM:Game Virtual Machine) 플랫폼(platform)을 내장한 휴대폰(011,017)으로 분류되며, 상기 플랫폼(platform)에 따라 휴대폰의 외부인터페이스를 통한 통신규약도 달라 필요한 휴대폰 연결케이블의 종류가 더욱 많아지고 그에 따라 휴대폰과 휴대폰을 케이블로 연결하여 게임을 하는 방식은 거의 현실성이 없어지는 문제점에 직면하였다.In addition, mobile phones currently supporting games include mobile phones (016, 018) with built-in BREW platform and mobile phones with GVM (Game Virtual Machine) platform (011, 017). According to the platform, the communication protocol through the external interface of the mobile phone is also different, so there are more types of mobile phone connection cables required, and thus, the game of connecting the mobile phone to the mobile phone by cable is almost unrealistic. Faced a problem.

본 발명은 상기와 같은 문제점을 해결하고자 하는 것으로서, 하나의 휴대폰 연결 케이블만을 휴대하여도 어떠한 휴대폰과도 통신이 가능한 통합된 커넥터를 제공하고, 나아가 휴대폰 연결 케이블의 크기를 작게 함과 동시에 제작비용을 절감할 수 있는 휴대폰 인터페이스장치를 제공함을 그 목적으로 한다.The present invention is to solve the above problems, to provide an integrated connector that can communicate with any mobile phone carrying only one mobile phone connection cable, and further reduce the size of the mobile phone connection cable and at the same time manufacturing costs It is an object of the present invention to provide a mobile phone interface device that can be reduced.

나아가 본 발명의 목적은 하나의 휴대폰 연결케이블로 서로 다른 플랫폼을 내장하고 있는 외부 휴대폰과 호스트 휴대폰 간에 게임을 위한 직렬통신을 가능하게 하는 휴대폰 인터페이스장치를 제공하는 것이다.Furthermore, it is an object of the present invention to provide a mobile phone interface device that enables serial communication for a game between an external mobile phone and a host mobile phone having different platforms embedded in one mobile phone connection cable.

It is desirable to be designed to be connected to a mobile phone to perform communication.

호스트 휴대폰 연결커넥터(11)와 외부 휴대폰 연결커넥터(12a, 12b)는 송신(Tx)단자, 수신(Rx)단자, 그라운드(GND)단자, 송신요구(RTS)단자 및 송신가능 (CTS)단자 및 신호데이터단말준비완료(DTR)단자와 휴대폰 접속부(1,2,3)를 포함한다.The host cellular phone connection connector 11 and the external cellular phone connection connectors 12a and 12b may include a transmit (Tx) terminal, a receive (Rx) terminal, a ground (GND) terminal, a transmit request (RTS) terminal, and a transmittable (CTS) terminal. A signal data terminal preparation completion (DTR) terminal and cellular phone connection portions 1, 2, and 3 are included.

본 발명의 바람직한 양상에 따라 호스트 휴대폰 연결커넥터(11)와 외부 휴대폰 연결커넥터(12a, 12b)의 송신요구(RTS) 단자와 송신가능(CTS) 단자는 각각의 커넥터 내에 서로 연결되어 있고, 호스트 휴대폰 연결커넥터(11)의 송신(Tx) 단자는 외부 휴대폰 연결커넥터(12a, 12b)의 수신(Rx) 단자와, 호스트 휴대폰 연결커넥터 (11)의 수신(Rx) 단자는 외부 휴대폰 연결커넥터(12a, 12b)의 송신(Tx) 단자와 호스트 휴대폰 연결커넥터(11)의 그라운드(GND) 단자는 외부 휴대폰 연결커넥터(12a, 12b)의 그라운드(GND) 단자와 연결되는 브릿지 방식으로 구성되어 있다.According to a preferred aspect of the present invention, the transmit request (RTS) terminal and the transmittable (CTS) terminal of the host cellular phone connection connector 11 and the external cellular phone connection connectors 12a and 12b are connected to each other in each connector, and the host cellular phone is connected to each other. The transmission (Tx) terminal of the connection connector 11 is a reception (Rx) terminal of the external cellular phone connection connectors 12a and 12b, and the reception (Rx) terminal of the host cell phone connection connector 11 is an external cellular phone connection connector 12a, The transmission (Tx) terminal of 12b) and the ground (GND) terminal of the host cellular phone connection connector 11 are configured in a bridge manner connected to the ground (GND) terminals of the external cellular phone connection connectors 12a and 12b.

휴대폰 접속부(1,2,3)는 18pin 혹은 24pin의 2가지 종류 중 하나가 될 수 있으며 휴대폰에 형성된 접속부와 연결되어 전기신호를 전달한다.Mobile phone connection (1, 2, 3) can be one of two types of 18pin or 24pin and is connected to the connection formed in the mobile phone to transmit the electrical signal.

도 2 는 본 발명의 제 2실시예에 따른 휴대폰 인터페이스장치의 외관도이다. 여기서, 도 1 과 대응되는 구성은 동일한 도면부호로 표시된다.2 is an external view of a mobile phone interface device according to a second embodiment of the present invention. Here, the components corresponding to those of FIG. 1 are denoted by the same reference numerals.

도 2 의 실시예에서, 외부 휴대폰 연결커넥터(12a, 12b)는 데이터단말준비완료(DTR) 단자와 그라운드(GND) 신호선의 연결을 단속하는 스위치(4a,4b)를 더 포함한다.In the embodiment of Fig. 2, the external cellular phone connection connectors 12a and 12b further include switches 4a and 4b for intermitting the connection between the data terminal ready (DTR) terminal and the ground (GND) signal line.

브루(BREW) 플랫폼을 내장한 휴대폰의 경우에는 데이터단말준비완료(DTR)단자를 사용하지 않지만 지.브이.엠(GVM:Game Virtual Machine) 플랫폼을 내장한 휴대폰의 경우에는 데이터단말준비완료(DTR)단자에 반드시 로우(Low)신호를 인가하여만 통신이 이루어진다. 따라서, 브루(BREW) 플랫폼을 내장한 휴대폰끼리 연결하는 커넥터의 경우에는 데이터단말준비완료(DTR)신호를 무시하면 되지만 브루(BREW) 플랫폼을 내장한 휴대폰과 지.브이.엠(GVM:Game Virtual Machine) 플랫폼을 내장한 휴대폰을 연결하는 커넥터의 경우에는 통신을 위해 데이터단말준비완료(DTR)단자가 직접 그라운드(GND)에 연결되어야 한다.For mobile phones with BREW platform, DTR terminal is not used, but for mobile phones with GVM (Game Virtual Machine) platform, data terminal ready (DTR) Communication is only done by applying a low signal to the terminal. Therefore, in case of a connector that connects mobile phones with a built-in BREW platform, the data terminal ready (DTR) signal can be ignored, but a mobile phone and a GVM (GVM: Game Virtual) with a built-in BREW platform can be ignored. In the case of a connector connecting a mobile phone with a built-in machine platform, a data terminal ready (DTR) terminal must be directly connected to ground (GND) for communication.

본 실시예에서 외부 휴대폰 연결커넥터(12a, 12b)는 스위치(4a,4b)를 추가로장착하므로써 하나의 휴대폰 연결케이블로 서로 다른 플랫폼을 내장하고 있는 외부 휴대폰과 호스트 휴대폰 간에도 게임을 위한 직렬통신을 가능하게 하는 것이다.In this embodiment, the external mobile phone connection connectors 12a and 12b are equipped with additional switches 4a and 4b so that serial communication for gaming can be performed between the external mobile phone and the host mobile phone which have different platforms embedded in one mobile phone connection cable. To make it possible.
