The OSA specifications define an architecture that enables application developer
23、s to make use of network functionality through an open standardized interface, i.e. the OSA APIs. The present document specifies the Multimedia Conference Web Service. The following are defined here: Name spaces. Sequence diagrams. Data definitions. Interface specification plus detailed method descr
24、iptions. Fault definitions. Service Policies.

The underlying model of the servic
32、e 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. There may exist a participant that is also the “owner“ of the conference, i.e. the user who can end the call an
33、d/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). NOTE: A call session a
34、llows the application to avail of other web service features that can add value to the created call session. For example the Audio Call web service can provide multimedia message delivery to call participants in the call session (playXxxMessage operation) and furthermore control of the media streams
35、 for the call participants thus enabling conversational multimedia communication including voice, video, chat, and data. Media can be added/removed for participants using the operations addMediaForParticipants and deleteMediaForParticipants in Audio Call. An application setting up a multimedia confe
36、rence 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, a callSessionIdentifier, is assigned to the just-created conference. At this stage no participant is
37、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 users terminal rings). If the application wishes to
38、 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 th
39、e 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 participants terminal. ETSI ETSI ES 202 504-12 V1.1.1 (2008-05) 9 During the conference session the application is able to: Add (or remove) a s
40、pecific 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 media control (addMediaForParticipants and the deleteMediaForParticipants) operations of the Audio Call web ser
41、vice. Disconnect a participant from the conference, by invoking the disconnectParticipant operation. 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 a
42、pplication may invoke the operation endConference, that “forces“ the termination 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 t
43、he conference (disconnected). 3) The conference duration exceeds a maximum value (specified during the conference creation step). 5 Namespaces The Multimedia Conference interface uses the namespace: http:/www.csapi.org/wsdl/parlayx/multimedia_conference/v3_1 The data types are defined in the namespa
