Method and system for providing service information through mobile communication device, mobile communication device, portable terminal, mobile communication management server, and computer-readable recording medium

摘要

An information provision method effectively utilizes a mobile communication infrastructure to offer a user-friendly communication service. A portable telephone is carried in a state of being separated from a user's body while a wrist-worn portable terminal is carried in a state of being maintained in direct contact with the user's wrist like a wristwatch. When the portable telephone receives service information during a main communication process, e.g., telephone conversation, it transfers the service information to the wrist-worn portable terminal. The wrist-worn portable terminal outputs and displays the transferred service information. A portable telephone company enables communication through the user's portable telephone by using a portable telephone communication infrastructure, and transmits service information to the portable telephone during intervals between time periods for the main communication process. A service information provider company provides an advertisement as service information to be transmitted to the user's portable telephone.
