The present invention relates to a method for providing an SMS message output function during a video call and a mobile communication terminal. In more detail, a mobile communication terminal providing a video call service scrolls an SMS message received during a video call directly on the video screen, such as a caption, so that the user can switch the video screen or check the video message during the video call. The present invention relates to a method and a mobile communication terminal for providing a function of outputting an SMS message during a video call that can immediately check a received SMS message without waiting for the end to be completed.

With the rapid development of computer, electronic and communication technologies, various wireless communication services using a wireless communication network have been provided. The most basic wireless communication service is a service for providing a voice call wirelessly between mobile terminal users regardless of time and place.

As a result of the development of communication technology, services provided by a code division multiple access (CDMA) system are not only voice call services, but also multimedia communication that transmits data such as circuit data and packet data. It is developing into a service.

In recent years, IMT-2000 (International Mobile Telecommunication 2000), a third generation mobile communication system that has been established as a standard by ITU-R due to the development of information and communication, has been commercialized. IMT-2000 is CDMA 2000 1X, 3X, EV-DO, Wide-band CDMA (WCDMA), etc. IS-95A, IS-95B using IS-95C network that has evolved from IS-95A and IS-95B networks. It is a service that can provide wireless data communication service at 144 Kbps, which is much faster than 14.4 Kbps or 56 Kbps, which is supported by the network. In particular, the IMT-2000 service can improve the quality of existing voice and wireless application protocol (WAP) services and provide various multimedia services at a faster speed.

Accordingly, the subscribers of the mobile communication service can freely move and talk with the other party anytime and anywhere using the wireless data communication service, as well as various information necessary for life through the wireless internet service, for example, news, weather, sports, securities. , Exchange rates, and traffic information may be provided in various forms such as text, voice, and image.
