For session invitation, an inviting terminal adds first media information corresponding to session information in an invitation message and transmits it or transmits it through an RTP. Then, the first media information received by an invited terminal is checked and an invitee determines whether to accept the invitation before joining the session. When the invitation is rejected, the invited terminal adds second media information corresponding to a reason for rejection in a reject message and transmits it, or transmits it through the RTP.
