Abstract

A system and method for easily checking the status of another party (e.g., driving or in conference) or the operational status of his terminal (e.g., busy, power-off, or reception rejected) without dialing the other party over an Internet Protocol (IP) network is provided. A mobile terminal generates a status information packet (SIP) and broadcasts the SIP over the IP network where other terminals receive the SIP and acquire the terminal's status without dialing. The states of other terminals can be displayed periodically in characters, icons or images on the LCD of a particular terminal or can be notified to a user by sounds or voice data.
