METHOD AND APPARATUS FOR GIVING MONOPOLY OF CALL IN CALL TRANSMISSION/RECEPTION SYSTEM USING UPNP

摘要

A method of giving a monopoly of a call in a call transmission/reception system using UPnP (Universal Plug and Play) includes a telephony server setting a user's authority to manage a session when the telephony server generates the session; the telephony server performing a user authentication when the telephony server receives a call for an action for managing the session from a control point; and the control point performing the action for managing the session if a user of the control point has an authority to manage the session as the result of authentication.
