4 Detailed service description
The Multimedia Conferencing is a simple Web Service that allows the creation of a multimedia conference and the
dynamic management of the participants and the media involved.
The underlying model of the service is based on the following entities:
• Conference: a "context" (uniquely identified) to which participants can be added/removed.
• Participant: each of the parties involved in the conference. Media can be added/removed for each participant.
There may exist a participant that is also the "owner" of the conference, i.e. the user who can end the call
and/or be the reference user for billing purposes.
• Media: the conference can utilize multiple media streams to support the participants' communication. In
particular both audio and video streams are available, including the specific stream direction (i.e. in, out,
bidirectional).
An application setting up a multimedia conference must initially invoke the createConference operation. The result of
such invocation is the creation of a "context" that represents a "virtual" room where users can "meet". A unique
identifier is assigned to the just-created conference. At this stage no participant is connected.
Subsequently the application may wish to add participants to the conference. In order to do so the operation
inviteParticipant can be used. The result of such an operation is to alert the user of the incoming connection request
(e.g. the user's terminal rings).
If the application wishes to check whether the user has accepted the invitation (i.e. is connected) it can invoke (at a later
time) the getParticipantInfo operation.
Note that:
• As soon as the first participant connects, the conference becomes "active". The duration of the conference is
then measured starting from the moment the conference has became active.
• The initial media set utilized by the participant will depend on the conference type and the media actually
supported by the participant's terminal.
During the conference session the application is able to:
• Add (or remove) a specific media stream to a single participant: e.g. adding a video bidirectional stream to a
participant that has an audio connection to the conference. This can be obtained by invoking the
addMediaForParticipant and the deleteMediaForParticipant operations.
• Disconnect a participant from the conference, by invoking the disconnectParticipant operation.

• Retrieve information related to the conference and its status, by invoking getConferenceInfo and
