본 발명은 이동통신 단말기에 관한 것으로, 특히 네트워크 프로그램간의 빠른 이동을 제어하는 이동통신 단말기의 채널 관리 장치 및 방법에 관한 것이다. The present invention relates to that, in particular, the channel management unit and method of a mobile communication terminal for controlling the fast movement between the network programs related to the mobile terminal.

일반적으로 이동통신 서비스 사업자(provider)는 사용자에게 무선 인터넷 접 속, VoD(Video on Demand) 서비스, 음성 통화, 문자 및 멀티미디어 메시지 전송 및 무선 온라인 게임 등과 같은 통신 기능과 연계한 기능들을 제공하고, 이동통신 단말기 제조사(manufacture)는 사용자에게 카메라, 메모 작성, 스케줄 관리, 모닝콜 기능 등과 같은 통신 기능과 연계하지 않고 자체적으로 수행하는 기능들을 제공한다. In general, mobile communication service providers (provider) will provide users with a communication function and linking features such as Wireless Internet Access, VoD (Video on Demand) services, voice calls, text and multimedia messaging, and wireless online gaming, and mobile communication handset manufacturers (manufacture) without the user associated with a communication function such as a camera, a memo writing, a schedule management, morning call and provides the capability to perform on its own.

이와 같이, 이동통신 단말기(이하 단말기라 칭함)에 제공되는 기능들은 앞으로 더욱 다양한 기능들이 제공되는 게 자명하며, 단말기를 통해서 앞으로 더 다양한 네트워크 프로그램들이 구동될 것이다. In this way, the mobile communication terminal (hereinafter referred to as a terminal) which function will be to drive more features are apparent to, and the terminal in the future more different network programs provided via the forward service.

브라우저, WIPI(Wireless Internet Platform for Interoperability), VoD(Video on Demand) 등과 같은 네트워크 프로그램들은 PPP(Point-to-Point Protocol)를 이용하여 데이터의 송수신을 한다. And to the sending and receiving of data using the network programs PPP (Point-to-Point Protocol) browser, such as, WIPI (Wireless Internet Platform for Interoperability), VoD (Video on Demand).

상기 PPP는 두 대의 컴퓨터가 직렬 인터페이스를 통해 통신을 할 때 사용되는 프로토콜로서, 대부분의 ISP(Internet Server Provider)들은 자신들의 가입자를 위해 인터넷 PPP 접속을 제공하고, 사용자의 요구에 응답하고, 서버를 통해 인터넷으로 나아갈 수 있도록 하며, 사용자 요구에 따른 응답을 다시 사용자에게 보내주는 등의 동작을 수행한다. The PPP is a protocol used to communicate via two computers serial interface, most of the (Internet Server Provider) ISP have to provide Internet PPP access for their subscribers, and to respond to your request, and the server and go through to make the Internet and perform an action, such as to send a response back to the user based on user requirements. 상기 PPP는 IP를 사용하며, 때로 TCP/IP 군의 하나로 간주되며 OSI(Open Systems Interconnection) 참조 모델과 비교하면 제2 계층에 해당되는 데이터링크 서비스를 제공한다. The PPP uses the IP, is considered as one of the times TCP / IP group when compared with the OSI (Open Systems Interconnection) reference model, and provides the Data Link service corresponding to the second layer.

그런데, 종래에는 사용자가 단말기를 통해 브라우저, WIPI, VoD 등과 같이 네트워크 프로그램을 사용하는 중에 다른 네트워크 프로그램을 사용하게 되면, 단 말기는 기존에 사용되었던 프로그램에 해당되는 PPP를 CLOSE 하고, 사용하기 위해 선택된 새로운 프로그램에 해당되는 PPP를 OPEN 한다. By the way, conventionally, the user and The use of different network programs while using the network program such as a browser, WIPI, VoD through the terminal, provided that the end of the CLOSE, and selected in order to use the PPP corresponding to that has been used in the existing program the OPEN PPP, which corresponds to the new program. 즉, 종래 단말기는 다양한 프로그램을 번갈아 사용하는 경우 PPP를 OPEN/CLOSE 과정을 사용되는 프로그램 수에 맞게 반복적으로 수행한다. That is, the conventional device is repeatedly performed for the number of programs using the PPP OPEN / CLOSE process if the alternating use of various programs. 이와 같이, 종래 단말기는 단말기에 구비된 네트워크 프로그램들이 각각 PPP OPEN, PPP CLOSE를 독립적으로 가지고 있기 때문에 기존 프로그램에 사용된 PPP를 CLOSE 할 때 트래픽 채널까지 끊어 버리고, 새로운 프로그램에 해당되는 PPP를 OPEN할 때 다시 트래픽 채널을 OPEN한다. Thus, the conventional device, since the network programs have a PPP OPEN, PPP CLOSE independently each provided with a terminal to CLOSE the PPP using the existing program abandoned cut off to the traffic channel, to OPEN the PPP corresponding to new programs OPEN again when the traffic channel. 따라서, 트래픽 채널의 OPEN 및 CLOSE 될 때 이중으로 소요시간이 낭비되는 문제점이 있었다. Therefore, there is a problem that is a waste of time to double when the OPEN and CLOSE of the traffic channel.

따라서, 본 발명의 목적은 어플리케이션 실행 후, 다른 어플리케이션을 선택 및 실행할 경우, Dummy PPP를 이용하여 실행된 어플리케이션이 종료되더라고 일시적으로 상기 종료된 어플리케이션의 트래픽 채널을 유지하여 어플리케이션 변경에 따른 트래픽 채널의 Open/Close 과정을 수행하는데 소요되는 시간을 줄이는데 있다. Therefore, after the object of the invention is the application running, if selected and to execute another application, Dummy that using the PPP by running the application is terminated doedeo to temporarily maintain the traffic channel of said end applications of the traffic channel in accordance with the application change It can reduce the time it takes to do the Open / Close process.

이하, 첨부한 도면을 참조하여 본 발명의 바람직한 실시 예를 설명한다. With reference to the accompanying drawings will be described a preferred embodiment of the present invention.

우선 본 발명을 설명함에 있어서, 관련된 공지기능 혹은 구성에 대한 구체적인 설명이 본 발명의 요지를 불필요하게 흐릴 수 있다고 판단된 경우 그 상세한 설명은 생략한다. First, the description of the present invention, a detailed description of known functions and configurations are determined to be unnecessarily obscure the subject matter of the present invention and a detailed description thereof will be omitted.

또한, 하기의 설명에서 구체적인 처리흐름과 같은 많은 특정 상세한 설명들은 본 발명의 보다 전반적인 이해를 제공하기 위해 나타나 있으며, 이들 특정 상세한 설명들 없이 본 발명이 실시될 수 있다는 것은 이 기술 분야에서 통상의 지식을 가진 자에게는 자명할 것이다. In addition, for many specific details such as specific process flow in the description of the are and appear to provide a thorough understanding of the present invention, these is that the specific details of the can to which the present invention is carried out without the ordinary skill in the art it will be apparent to those of.

본 발명의 기본 개념은 단말기에 구비된 네트워크 프로그램들을 번갈아 사용할 경우 Dummy PPP를 이용하여 기존 프로그램에 해당되는 PPP를 잠시 유지시켜주고, 트래픽 채널을 유지함으로써 새로 선택된 프로그램에 해당된 PPP를 OPEN 하는데 소요되는 시간을 줄이는 데 있다. The basic idea of ​​the present invention when it is used alternately in the network program provided in the terminal using Dummy PPP give to briefly maintain the PPP corresponding to the original program, it takes to OPEN the PPP corresponding to the newly selected program by maintaining a traffic channel It is to reduce the time.

도 1은 본 발명에 따른 이동통신 단말기의 프로그램 변환 장치를 나타낸 블록도이다. Figure 1 is a block diagram showing a program conversion apparatus of the mobile communication terminal according to the present invention.

도 1에 도시된 바와 같이, 본 발명에 따른 단말기는 VoD, WIPI, 브라우저 등의 프로그램들을 이용하기 위한 명령을 입력하는 입력부(10)와, 상기 입력된 명령을 제어하고, 단말기 시스템 전체를 제어하는 제어부(20)와, 상기 제어된 명령을 송신하거나, 송신된 명령으로 인한 해당 서버, ISP 등으로부터 데이터를 수신하는 송/수신부(30)와, 수신된 데이터를 디스플레이하는 표시부(40)와, 상기 VoD, WIPI, 브라우저 등의 프로그램들이 구비된 기능부(50)와, 사용자의 선택에 의해 프로그램 변경시, 해당 프로그램의 채널 및 PPP를 변경 및 관리하는 채널 관리부(60)를 포함하여 구성된다. 1, the device according to the invention is VoD, WIPI, and the input unit 10 for inputting an instruction to use a program such as a browser, controlling the input instruction, and that controls the entire terminal system the control unit 20 and, with the transmitting / receiving unit 30 for transmitting the control commands, or receive data from the servers, ISP, etc. due to the transmission command, and displaying the received data to display unit 40, the VoD, is WIPI, and a browser program such as a functional section (50) are provided, configured to include a channel management unit 60 to change and manage the hour, and the PPP channel for the program to change the program by the user's selection.

이하, 도1을 참조하여 본 발명에 따른 이동통신 단말기의 프로그램 변환 장치의 동작을 설명하면 다음과 같다. Hereinafter, Referring to Figure 1 to explain the operation of the program conversion apparatus of the mobile communication terminal according to the present invention.

입력부(10)를 통해 사용자로부터 소정 프로그램(즉, 어플리케이션)을 실행하기 위한 명령이 입력되면, 제어부(20)는 상기 입력부(10)로부터 입력된 명령에 따라 다수의 프로그램이 구비된 기능부(50)를 제어하여 해당 프로그램을 실행시킨다. Once through the input unit 10 inputs an instruction to execute a predetermined program (i.e., application) by the user, the control unit 20 with a plurality of programs provided in accordance with the command input from the input unit 10, the function unit (50 ) controls and executes the program. 실행된 프로그램은 표시부(40)에 디스플레이되며, 상기 실행된 프로그램이 통신을 이용하는 프로그램이면, 단말기는 PPP를 이용한 통신을 통해 송/수신부(30)를 통해 서버 또는 상대방 단말기와의 통신을 수행한다. The program execution is displayed on the display 40, when the the executed application program using the communication terminal performs communication with the server or the other terminal through the transmitting / receiving unit 30 via the communication using the PPP. 상기 PPP는 Application ID와 Net LIB의 형식적인 ACB(Application Control Block)를 가진다. The PPP has a (Application Control Block) formal ACB of the Application ID and Net LIB. 상기 ACB에는 Phylink_iface 구조체와, Iface 구조체를 가지며, 상기 Phylink_iface 구조체는 트 래픽을 얼라이브(alive)하기 위해 물리적인 채널을 유지하기 위한 구조체이며, 상기 Iface 구조체는 표면적으로 들어나는 상태를 유지하기 위한 구조체이다. The ACB contains has a Phylink_iface structure and, Iface structure, the Phylink_iface structure is a structure for maintaining the physical channel to alive (alive) the traffic, the Iface structure is a structure for holding the example I condition the surface .

Dummy PPP는 이와 같이 항상 처음 만들어진 PPP 다음에 다시 PPP를 만들어 지므로 ACB의 Phylink_iface가 불필요하고, Iface의 구조체만 유지한다. Dummy PPP was created because back then PPP PPP always initially created in this manner and the ACB of Phylink_iface unnecessary and only the holding structure of Iface. 그 이유는 이미 트래픽 채널이 열려 있으므로 Dummy PPP는 기존의 트래픽 채널을 이용하기 때문이다. The reason is because it is already a traffic channel is open Dummy PPP is that using the existing traffic channel. 이와 같이 일반 PPP와 Dummy PPP를 가지고 다른 프로그램(즉, 어플리케이션)을 접속 했을 때 일반 PPP는 끊어지면서, 종료 절차를 수행한 후, 또 다른 ACB가 존재하므로 현재 망에서 연결되어 있는 PPP를 가지고 다른 프로그램을 선택 및 실행을 할 수가 있다. Thus, after having the general PPP and Dummy PPP when connecting other programs (i.e., applications) This PPP is As disconnected, perform a shutdown process, and so another ACB is present have a PPP which is connected in the current network, the other program the selection can be up and running.

이와 같이, 서버 또는 상대방 단말기와 통신을 수행하는 중에, 사용자가 다른 프로그램을 실행하고자 입력부(10)를 통해 명령을 입력하면 상기 제어부(20)는 기능부(50)와, 상기 다른 프로그램을 실행하기 위한 채널을 변경하는 채널 관리부(60)를 제어하여 해당 프로그램을 실행한다. Thus, while performing the server or the other terminal to communicate with, when the user inputs a command through the input unit 10 to execute a different program to execute the above control unit 20 is the function unit 50, the other program controlling the channel management unit 60 to change the channel for the program to be executed.

도 2는 본 발명에 따른 Dummy PPP를 이용한 채널 변환 방식을 나타낸 도면이다. Figure 2 is a diagram showing a channel conversion method using a PPP Dummy in accordance with the present invention.

도 2에 도시된 바와 같이, Dummy PPP는 실제 소켓(socket)을 사용하거나 어플리케이션을 가지고 있지 않지만, PPP 간의 이동(네트워크 프로그램들 간의 이동)을 위해 잠시 PPP를 유지시켜주는데 목적이 있다. Fig, Dummy PPP has juneunde was maintained while PPP for use real socket (socket), or does not have an application movement between the PPP (movement between network program) object as shown in Fig. 즉, PPP가 유지되고 있다는 것은 트래픽 채널도 유지되고 있다는 것을 의미하며, PPP를 새로 Open하는데 있어 빠른 진행이 가능하다. In other words, it is maintained that the PPP means that the traffic channel is maintained, it is possible to Open a new PPP rapid progress.

이러한 Dummy PPP의 사용 용도는 PPP가 완전히 종료 되었을 때(즉, 살아있는 PPP가 하나도 없을 때) 트래픽 채널도 끊어버리지만, 만일 PPP가 하나라도 살아 있으면 트래픽 채널은 끊어지지 않고 유지된다. Purpose of this is when a Dummy PPP PPP has been completed (that is, when the PPP not live none) only discard the traffic channel is also cut off, PPP is maintained if there is even one live traffic channel without interruption. 이와 같이, 트래픽 채널이 유지되는 이유는 PPP의 Application ID와 Net LIB의 형식적인 기본 ACB를 가지기 때문이며, 이와 같이 기본 ACB를 가져야만 Application ID를 유지할 수 있으므로 Dummy PPP는 PPP가 있어야 하는 기본값만 가지고 채널을 유지할 수 있는 것이다. Thus, the reason for maintaining the traffic channel because gajigi formal basic ACB of the Application ID and Net LIB of the PPP, so this way you can keep your Application ID must have the basic ACB Dummy PPP channel has only the defaults to have a PPP which will be maintained. 그러므로, Dummy PPP는 PPP Open 시점에서 시간이 소용되는 부분들은 망과 트래픽을 생성하기 위해 드는 것이 대부분이므로 트래픽 채널을 유지하고 Application을 새로 여는 것이므로 접속 시간대를 줄일 수 있다. Therefore, Dummy PPP because it is the most favorite for the time being are part time stations in PPP Open to create a network of traffic maintained on the traffic channel, and because opening a new Application can reduce the connection time.
