1 Scope
The present document is part 4, sub-part 4 of the Stage 3 specification for an Application Programming Interface (API)
for Open Service Access (OSA).
The OSA specifications define an architecture that enables application developers to make use of network functionality
through an open standardised interface, i.e. the OSA APIs.
The present document specifies the Multi-Media Call Control Service Capability Feature (SCF) aspects of the interface.
All aspects of the Multi-Media Call Control SCF are defined here, these being:
• Sequence Diagrams
• Class Diagrams
• Interface specification plus detailed method descriptions
• State Transition diagrams
• Data Definitions
• IDL Description of the interfaces
• WSDL Description of the interfaces
• Reference to the Java API description of the interfaces
The process by which this task is accomplished is through the use of object modelling techniques described by the
Unified Modelling Language (UML).

4 MultiMedia Call Control Service Sequence Diagrams
4.1 Barring for media combined with call routing, alternative 1
This sequence illustrates how one application can influence both the call routing and the media stream establishment of
one call.
In this sequence there is one application handling both the media barring and the routing of the call.

1: The application creates a AppMultiMediaCallControlManager interface in order to handle callback methods.
2: The application expresses interest in all calls from subscriber A. Since createNotification is used and not
createMediaNotification all calls are reported regardless of the media used.
3: A makes a call with the SIP INVITE with SDP media stream indicating video. The application is notified.
4: The event is forwarded to the application.
5: The application creates a new AppMultiMediaCallLeg interface to receive callbacks.
6: The application sets a monitor on video media streams to be established (added) for the indicated leg.
7: Since the video media stream was included in the SIP invite, the media streams monitored will be returned in the
monitor result.
8: The event is forwarded to the application.
9: The application denies the video media stream, i.e., it is not included in the allowed media streams. This
corresponds to removing the media stream from the setup.

10: The application requests to reroute the call to a different destination (or the same one.)
11: Later in the call the A party tries to establish a lower bandwidth video media stream. This is again reported with
MediaStreamMonitorRes.
12: The event is forwarded.
13: This time the application allows the establishment of the media stream by including the media stream in the allowed
list.
4.2 Barring for media combined with call routing, alternative 2
This sequence illustrates how one application can influence both the call routing and the media establishment of one
call.
Media establishment and call establishment are regarded separately by the application.
From the gateway point of view it can actually be regarded as two separately triggered applications, one for media
control and one for routing. This is also the way that it is shown here, for clarity.
However, an implementation of the application could combine the media logic and call logic in one object.

1: The application creates a new AppMultiMediaCallControlManager interface.
2: The application expresses interest in all calls from subscriber A for rerouting purposes.
3: The application creates a new AppMultiMediaCallControlManager interface. This is to be used for the media
control only.

4: Separately the application expresses interest is some media streams for calls from and to A. The request indicates
interrupt mode.
5: Subscriber A makes a call with the SIP INVITE with SDP media stream indicating video. Since the media
establishment is combined with the SIP INVITE message, both applications are triggered (not necessarily in the order
shown). Here the call application is notified about the call setup.
6: The event is forwarded to the call control application.
7: The call control application creates a new AppMultiMediaCall interface.
8: The call control application creates a new AppMultiMediaCallLeg interface.
9: The media application is notified about the call setup. All media streams from the setup will be indicated.
10: The event is forwarded to the media application.
11: The call control application creates a new AppMultiMediaCallLeg interface.
12: The call application decides to reroute the call to another address. Included in the request are monitors on answer
and call end. However, since the media was also triggered in mode interrupt the call will not proceed until the media
streams are confirmed or rejected.
14: The application allows the audio media stream, but refuses the high bandwidth video, by excluding it from the
allowed list. Since both call processing and media handling is now acknowledged, the call routing can continue (with a
changed SDP parameter reflecting the manipulated media).
15: The Media application is no longer interested in the call.
16: When the B subscriber answers the call application is notified.
17: The event is forwarded to the call application.
19: When later in the call A tries to establish a lower bandwidth video stream the media application is triggered.
20: The triggering is forwarded to the media application.
21: The application now allows the establishment of the media stream by including the media stream in the
mediaStreamAllow list.
22: The media application is no longer interested in the call.
4.3 Barring for media, simple
This sequence illustrates how an application can block the establishment of video streams for a certain user.
