TWO-WAY COMMUNICATION SYSTEM BETWEEN MOBILE COMMUNICATION TERMINALS AND INTERNET TERMINALS AND METHOD THEREOF

摘要

PURPOSE: A two-way communication system between mobile communication terminals and internet terminals and a method thereof are provided to achieve two-way communication between mobile communication terminals and internet terminals. CONSTITUTION: List data for intimate persons are displayed on an LCD window by a user, in the form of character information, such as e-mail accounts, names, etc., or numbers, such as telephone numbers(S410). The PCS user selects character information corresponding to a person whom the user wants to call among the intimate persons list and pushes a transmission button(S411). The signal from the PCS terminal is transmitted to an internet call providing server to confirm whether the PC of a receiver is in on-line state(S412). The internet call providing server identifies the receiver through his ID transmitted(S413). In case that the receiver is not in on-line state, the internet call providing server transmits a corresponding signal to the PCS terminal(S414). If in on-line state, the internet call providing server transmits the IP information of the PC to the PCS terminal(S416). The PC user cancels call if the receiver is in off-line state(S415) and pushed the call button if he is in on-line state(S417).
