<p>A method for an announcement for a session includes: adding at least one playing termination in a context of a session; setting up a topology descriptor between a playing termination and a termination which is about to listen to the announcement in the context; and playing the announcement by the playing termination to the termination connected to the playing termination. An apparatus for an announcement for a session includes a playing termination setting unit, a topology descriptor setting unit and an announcement-playing unit. The present invention ensures that a user can always hear complete announcement even when a termination operable for playing an announcement is deleted or removed from the context and thus cannot play the announcement any more.</p> |
