The most basic mobile communication service is a wireless voice call service that provides a voice call to a mobile terminal user wirelessly, which can provide a service regardless of time and place. In addition, while supplementing a voice call service by providing a text message, a wireless Internet service has recently emerged to provide an Internet service to a user of a mobile communication terminal through a wireless communication network.

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

The mobile communication system has been developed through the first generation analog AMPS (Advanced Mobile Phone System) method and the second generation cellular (Cellular) / Personal Communication Service (PCS) method. The third generation mobile communication system IMT-2000 (International Mobile Telecommunication 2000), which is enacted as a standard in ITU-R, is commercially available. IMT-2000 is CDMA 2000 1X, 3X, EV-DO, Wideband CDMA (WCDMA), etc., and 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 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 wireless broadcasting service (WBS) service quality.
