Description

System for providing Multimedia Advertisement Service by using Wireless Communication Terminal}

The present invention relates to a multimedia content service of a mobile communication system. More particularly, the present invention relates to a multimedia advertisement system and method for playing an advertisement when playing multimedia content provided to a mobile communication terminal.

With the rapid development of computer, electronic and communication technologies, various wireless communication services using wireless networks have been provided. The most basic wireless communication service is a wireless voice call service that provides voice calls wirelessly between mobile terminal users regardless of time and place. Recently, a wireless Internet service has emerged that provides a communication service using the Internet through a mobile communication network while a user of a mobile communication terminal moves without restriction of a place. The wireless Internet service uses WAP (Wireless Application Protocol), which enables a smooth exchange of data between a wireless communication network and an internet network having different communication protocols. WAP is a general term for a communication protocol that allows the Internet to be used through a mobile communication terminal such as a mobile phone or a personal digital assistant. In order to solve the problem of the slow communication speed of wireless communication, the WAP does not transmit a text code on the Internet as it is, but converts it into a binary code in a WAP server and transmits it to a mobile terminal. In addition, the WAP is designed considering the contents and the mobile communication terminal to use the WAP from the model design, so that users can use the Internet only with the mobile communication terminal. That is, it is designed to directly call a mobile communication terminal corresponding to a telephone number retrieved from the Internet, and to input a letter or assign a button for each content by combining buttons on the mobile communication terminal. Therefore, the users of the mobile communication service can freely move and talk with the other party anytime and anywhere by using the wireless communication service, and through the wireless Internet service using the WAP, information necessary for life, for example, news, weather, sports, Securities, exchange rates, traffic information, etc. can be provided in various forms such as text, voice, and image.

Furthermore, in recent years, with the development of information and communication, IMT-2000 (International Mobile Telecommunication 2000), a third generation mobile communication system that has been standardized by ITU-R (for example, CDMA2000 1X, 3X, EV-DO, WCDMA (WideBand) CDMA) will soon be commercially available to the public. IMT-2000 is a CDMA 2000 1X, 3X, EV-DO, WCDMA (WideBand CDMA), etc., which is used in IS-95A and IS-95B networks by using the IS-95C network that has evolved from the existing IS-95A and IS-95B networks. It is a service that enables wireless Internet at a transmission speed of up to 144 Kbps, much faster than the supportable data transfer rate of 14.4 Kbps or 56 Kbps. Through IMT-2000 service, it is possible to provide the multimedia service (AOD, VOD, etc.) including the real-time video transmission as well as the improvement of the existing voice and WAP service quality. Video transmission uses streaming technology that divides a large amount of multimedia and transmits it in real time. Streaming technology provides users with multimedia streaming of news, sporting events, and movies that have been broadcast through conventional airwaves. Multimedia streaming starts playback even if a part of the multimedia file is received but not all of it, and continuously receives a part of the multimedia file while it is being played.

Nevertheless, it takes a considerable amount of time to download the multimedia contents from the multimedia system to the mobile communication terminal and the connection fee accordingly must be paid. Therefore, there is an urgent need for a service that can use multimedia contents at a lower cost.

Therefore, it is an object of the present invention to provide a multimedia advertising system including an advertisement to a mobile communication terminal, and to provide a multimedia advertisement system in which the multimedia content provided to the mobile communication terminal is played together with the advertisement.
