With the recent development of communication and semiconductor technology, mobile phones are equipped with various multimedia additional functions, and are expanding their roles into the area of personal mobile servers beyond the simple voice call device.

The technological development of mobile phones can be divided into two parts as follows.

One is the development of communication performance of mobile phones according to the development of communication technology. Synchronous mobile phones have evolved into IS-95, CDMA2000, 1X and 1X EV-DO, while asynchronous mobile phones have evolved into WCDMA R4, HSDPA R5 and HSUPA R6. As a result of this development, the data transmission speed of mobile phones, which was initially several kbps, recently improved to several Mbps.

Another development is the enhancement of multimedia add-ons for mobile phones. The development of additional functions of mobile phones has been made in various multimedia areas such as wider and larger color LCDs, improved sound quality, various input methods, cameras, MP3 and video playback, and video call functions.
