Although a PoC client providing an Open Mobile Alliance (OMA) PoC multimedia communication service supports a plurality of uncommon types of media, it is possible to open a session according to media types in an independent and easier manner. Also, when a new media type is supported by a new participant during a session, it is possible to add the new media type when granting the next floor. In addition, it is possible to selectively transmit media according to media types based on the PoC user's choice.
