The idea of incorporating additional option circuits into the battery pack has been proposed to expand the functionality of mobile terminals. For example, Japanese Patent Laid-Open No. 9-270836 published October 14, 1997 discloses an additional device in which a radio circuit embedded in a battery pack is detachably coupled to a mobile communication terminal. As another example, Korean Patent Laid-Open Publication No. 2001-19664, filed by Kim Tae-jin and published on March 15, 2001, includes an MP3 codec and a flash memory module in a battery pack of a mobile communication terminal, and controls the user interface of the mobile communication terminal.
