TECHNICAL FIELD [0001] The present invention relates to a system and a method for providing additional information to an SMS service,

The present invention relates to a technology for providing information related to an SMS service to a user, and more particularly, to satisfy SMS requirements of a service provider for an SMS service, new parameters not mentioned in 3GPP specifications are additionally defined And more particularly, to a system and method for providing additional information to an SMS service for providing a user with various additional information on an SMS service.

Since Internet communication services, which are symbolized by the World Wide Web, have begun to attract attention, communication services have already made a big difference in human life in all aspects such as society, economy and politics. It is a reality that the Internet is perceived as a part of life so that it is hard to imagine a life that can not do the Internet. Recently, the spread of high-speed communication networks has been greatly increased in order to use various communication services in a better environment.

However, the communication service such as the Internet using a computer has an advantage that the transmission speed is high and the data input is convenient. However, when the user can not use the communication service such as the Internet, Service.

Recently, many telecommunication companies are spurring on the development of a new technology called wireless Internet in order to provide a communication service such as internet over space. The wireless Internet refers to an environment and technology in which a user can use an Internet service through a wireless network while moving using a mobile communication terminal. The development of mobile communication technology and the dramatic increase in the penetration rate of mobile communication terminals further promoted the development of such wireless Internet environment.

Due to the development of the wireless Internet environment, the mobile communication service provider or the special communication service provider is providing various useful services to the users of the wireless Internet, thereby further promoting the use of the wireless Internet by the users. Such wireless Internet services include text messages, e-mail, cards, letters, games, geographical / living information, learning, and comics.

In particular, the SMS message service refers to a service for transferring a text message of a limited length from a computer connected to the Internet to a mobile communication terminal or between mobile communication terminals regardless of whether the mobile communication subscriber is in a call state or not. The SMS message service, which can transmit 80 bytes (80 characters in English and 80 characters in English) on the LCD screen of a mobile communication terminal, is expanding its usage range from personal use to enterprise use, to be. In other words, recent SMS is not only for the purpose of simple inter-personal message transmission but also for inter-group transmission, reservation transmission, e-mail arrival notification, personal information management, security information notification, product information notification, financial information notification, And is widely used for a wide variety of applications.

Here, the callback number transmission in the SMS message service is not only a function of simply transmitting the telephone number of the caller, but also transmitting a specific URL (Uniform Resource Locator) address information for wireless Internet access, And a function of automatically accessing a wireless Internet web page having a corresponding URL by pressing only a specific button.

However, as the mobile communication system evolves, a related standard for SMS message service should be newly defined according to the evolution path. That is, depending on whether the current second generation (2G) or 2.5th (2.5G) mobile communication system evolves into a synchronous third generation (CDMA 2000) or asynchronous third generation (WCDMA) It should be newly defined.

At present, the WCDMA communication method is a wireless protocol recommended by IMT-2000, and many communication service providers are providing or are preparing to provide it to the world. The W-CDMA system has a high communication quality and uses the spread spectrum method, which is advantageous for a large amount of data transmission. The WCDMA system adopts 32 Kbps Adaptive Differential Pulse Code Modulation (ADPCM) for voice coding and supports high mobility even when the user moves at a speed of about 100 km / h.

In addition, the WCDMA communication system is adopted by the largest number of countries, and many organizations such as Korea, Europe, Japan, the United States, and China constitute 3GPP (Third Generation Partnership Project) to develop a technical specification for WCDMA Going out.

However, the standard related to the SMS message service defined in the current WCDMA system is only related to the transmission of the SMS message. Accordingly, in the current WCDMA communication system, it is not possible to provide a callback number service related to a telephone number of a caller, a specific URL access function, or the like, which is provided in an SMS message service of 2G or 2.5G. Therefore, there is a limit in providing various and convenient functions to mobile communication subscribers using the WCDMA system.
