32、rvice 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 i
33、dentified) 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 us
34、er 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 confere
35、nce 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
36、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 users terminal rings). If the application wishes to check whether the user has
37、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 acti
38、ve. The initial media set utilized by the participant will depend on the conference type and the media actually supported by the participants 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 bidir
39、ectional 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. ETSI ETSI ES 202 3
40、91-12 V1.3.1 (2008-05) 8 Retrieve information related to the conference and its status, by invoking getConferenceInfo and getParticipants. There are different conditions that can determine the end of the conference: 1) The application may invoke the method endConference, that “forces“ the terminatio
41、n of the conference and the disconnection of all participants. 2) The owner of the conference (if defined) leaves the conference. If the owner is not defined this condition will apply when all the participants have left the conference (disconnected). 3) The conference duration exceeds a maximum valu
