Abstract

PURPOSE: A fax transmission method for a smart phone is provided to automatically select a line with good quality and transmit a fax when a fax can be transmitted by wire/wireless due to the smart phone connected to the PSTN(Public Switched Telephone Network). CONSTITUTION: A second CPU of a PDA(Personal Digital Assistant) part discriminates whether a user inputs a fax transmission command(21). If a fax transmission command is input, it is discriminated whether the PDA part of a smart phone is connected to the PSTN(22). When a RJ11 jack is inserted, so the smart phone is connected to the PSTN, the second CPU reads the fax data stored to a second memory and then transmits through the jack by a modem, thereby transmitting the fax by wire(23). When the smart phone is not connected to PSTN, the fax is transmitted by a built-in wireless network(24).

그리고, 제1,2CPU(105, 108)는 주변 구성 블록들을 제어하여 데이터를 송수신하고, 스마트폰이 갖는 각종 기능을 실행할 수 있도록 제어한다.The first and second CPUs 105 and 108 control peripheral blocks to transmit and receive data, and execute various functions of the smart phone.

도 2는 본 발명에 의한 스마트폰에서의 팩스 전송 방법의 흐름도이다.2 is a flowchart of a fax transmission method in a smartphone according to the present invention.

그러면 도 1의 구성을 참조하여 도 2의 흐름도를 중심으로 본 발명을 설명하기로 한다.Next, the present invention will be described based on the flowchart of FIG. 2 with reference to the configuration of FIG. 1.

단계21에서는 PDA부분(1B)의 제2CPU(108)는 I/O모쥴(109)에 의하여 사용자가 팩스 전송 명령을 입력하였는가를 판단한다.In step 21, the second CPU 108 of the PDA portion 1B determines by the I / O module 109 whether the user inputs a fax transmission command.

즉, 사용자가 I/O모쥴(109)의 키보드 또는 다른 입력 수단을 이용하여 팩스 전송문을 작성하고 나서 팩스 전송 명령을 입력하는 경우에, 제2CPU(108)가 이 팩스 전송 명령이 입력되었는가를 판단한다.That is, when the user enters a fax transmission command after creating a fax transmission message using the keyboard of the I / O module 109 or other input means, the second CPU 108 determines whether this fax transmission command has been entered. To judge.

단계22에서는 단계21의 판단 결과 팩스 전송 명령이 입력된 경우에, 스마트폰의 PDA부분(1B)이 PSTN망에 접속되어 있는가를 판단한다.In step 22, when the fax transmission command is input as a result of the determination in step 21, it is determined whether the PDA portion 1B of the smartphone is connected to the PSTN network.

즉, 제2CPU(1B)는 PDA부분(1B)이 RJ11소켓(113)을 통하여 PSTN망에 접속되어 있는지를 판단한다.That is, the second CPU 1B determines whether the PDA portion 1B is connected to the PSTN network via the RJ11 socket 113.

만일 PDA부분(1B)이 PSTN망에 RJ11소켓(113)의 잭에 의하여 접속되어 있지 않은 경우에는 단계24에 의하여 CDMA망을 이용하여 팩스를 전송한다. 즉, 제2메모리(111)에 저장되어 있는 팩스 전송 데이터를 제2CPU(108)가 리드하고, 제1시리얼 인터페이스(107)를 통하여 CDMA부분(1A)으로 보내면 제1시리얼 인터페이스(106)를 통하여 제1메모리(104)에 버퍼링한 후에 제1CPU(105)에 리드 명령에 의하여 CDMA모쥴(102) 및 RF모쥴(101)을 거친 후에, 안테나(100)를 통해 무선으로 팩스를 송신한다.If the PDA portion 1B is not connected to the PSTN network by the jack of the RJ11 socket 113, the fax is transmitted using the CDMA network in step 24. That is, when the second CPU 108 reads the fax transmission data stored in the second memory 111 and sends it to the CDMA portion 1A through the first serial interface 107, the first serial interface 106 transmits the data. After buffering in the first memory 104, the first CPU 105 passes through the CDMA module 102 and the RF module 101 by a read command, and then wirelessly transmits a fax through the antenna 100.

그러나, RJ11소켓에 잭이 꽂혀 있어 스마트폰이 PSTN망에 접속되어 있는 경우에는 단계23에 의하여 제2메모리(111)에 저장되어 있는 팩스 데이터를 제2CPU(108)가 리드한 후에, 모뎀(112)을 통하여 RJ11소켓에 꽂혀있는 잭을 통하여 PSTN망으로 전송되어 유선으로 팩스를 송신하게 한다.However, if the jack is plugged into the RJ11 socket and the smartphone is connected to the PSTN network, the modem 112 reads the fax data stored in the second memory 111 by step 23, and then the modem 112 ) Is sent to the PSTN network through the jack plugged into the RJ11 socket to send the fax by wire.

이와 같은 동작에 의하여 스마트폰이 PSTN망에 접속되어 있지 않는 경우에는 자체의 무선망을 통하여 팩스를 전송하고, 만일 스마트폰이 PSTN망에 접속되어 있는 경우에는 PSTN의 유선망을 통하여 팩스를 전송하게 제어함으로써, 보다 성능이 우수한 팩스 전송 방법을 선택하여 스마트폰에서 팩스를 전송할 수 있게 되었다.By this operation, if the smart phone is not connected to the PSTN network, it transmits the fax through its own wireless network, and if the smart phone is connected to the PSTN network, control to transmit the fax through the wired network of the PSTN. By doing so, it is possible to send a fax from a smartphone by selecting a higher performance fax transmission method.

상술한 바와 같이 본 발명에 의하면 스마트폰이 PSTN망에 접속되어 무선 또는 유선으로 팩스 전송이 가능한 경우에 스마트폰이 PSTN망에 접속되어 있는지를 판단하여 자동으로 유선의 PSTN망을 통하여 팩스를 전송하게 제어함으로써, 팩스 전송 성능이 우수하고, 빠른 속도로 팩스를 전송할 수 있는 효과가 있다.As described above, according to the present invention, when the smart phone is connected to the PSTN network and the fax transmission is possible by wireless or wired, it is determined whether the smart phone is connected to the PSTN network and automatically transmits the fax through the wired PSTN network. By controlling, the fax transmission performance is excellent and the fax can be transmitted at high speed.
