The present invention relates to a method and a system for providing a homepage service using a video telephone system. More specifically, by linking the video phone service and the homepage service, the user can access the homepage using a video telephone terminal or, if the video call fails, automatically access the homepage instead of accessing the video mailbox. The present invention relates to a method and system for providing a homepage service using a video telephone system that enables an interactive service.

Due to the development of mobile communication technology, the services provided by the code division multiple access (CDMA) mobile communication system are not only voice services but also multimedia for transmitting data such as circuit data or packet data. It is developing into a communication service.

In addition, with the development of information and communication, IMT-2000 (International Mobile Telecommunication 2000), which is a third generation mobile communication system established by ITU-R as a standard, has been commercialized. IMT-2000 is CDMA 2000 1X, 3X, EV-DO, WCDMA (WideBand CDMA), etc .. It is a service that can provide 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. In particular, by using IMT-2000 service, it is possible to provide various multimedia services (AOD, VOD, etc.) at a faster speed as well as improving existing voice and WAP service quality.

With the development of the communication service performance, the utility value of the video telephony system, which is a system capable of real-time processing of video and audio information based on hardware and software, and can communicate with each other at a distance, is gradually increasing. It is becoming. The use of such video telephony system can maximize business efficiency by improving business efficiency and making quick decision-making by eliminating frequent business trips in meeting-oriented cultures. It can be expected to have the side effect of facilitating the latest exchange of information between medical institutions, and can be used in medical institutions for patient management, telemedicine, and in the field of education.

The basic functions that video telephone terminals should have for communication with each other include video and audio input / output function and codec (Codec, Coder and Decoder) function, which is a video transmission device that compresses and encodes high resolution video data and audio data in real time, Communication control functions for controlling communication between terminals are required, and additionally, user data transmission, video message storage, and collaboration functions are required. In order to develop a video telephone system having these basic functions, a transmission path is required. Several factors should be considered, including the form and quality of the components, the methods for intercommunication and the relevant standards and applied technologies.

Meanwhile, as information technology advances to the information society, the Internet is becoming an important and essential medium in all fields such as society, culture, and economy. Accordingly, users who use the Internet produce and operate an Internet home page using a web browser as a means of promoting themselves.

Such an Internet homepage (hereinafter referred to as a 'homepage') is a web such as HTML (Hypertext Markup Language) syntax or a Namo web editor, which is a markup symbol or a set of codes included in a file for displaying information on a webpage. It is difficult for general users to create and manage their own homepage because it is produced using a tool for creating a page.

In order to solve these difficulties in creating and managing homepages, a mini homepage or blog service is provided to a large number of subscribers on the Internet, and they have their own homepage through simple membership registration or input and selection of information. Profile-based personalized community services such as Cyworld (URL: cyworld.nate.com) and SayClub (URL: www.sayclub.com) are available.

In addition, due to the rapid growth of the mobile telecommunications service market, mobile telecommunications service providers have established wired homepages by cooperating with wired personal community service providers in order to provide the mobile homepages of wired networks to mobile subscribers using wireless networks that provide mobile telecommunication services. Provides wireless homepage service by converting to fit wireless environment.

However, since the wireless homepage service using the wireless Internet requires a data call connection, only a limited service such as data inquiry is possible, and there is a disadvantage in that the interactive function is weak.
