Abstract:
Disclosed is a system for displaying on calling partner terminal during call waiting information on a wireless terminal received via an Internet server through which a user stores a call connection community screen, with a message containing a call connection community screen is received via the Internet server and displayed for a calling partner during a call waiting in a wireless terminal. A predetermined field of the message is checked when a message is received from the messaging server in a call waiting status. If the predetermined field has a specific set value, the call connection community screen is extracted from the message and displayed on a display window, with the call connection community screen containing information of the calling partner. User individuality can be visually expressed to the calling partner during the call waiting and the call waiting time can be more efficiently utilized through the interactive screen.
