1 Scope
The present document is part 4, sub-part 5 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 Conference Call Control Service Capability Feature (SCF) aspects of the interface.
All aspects of the Conference 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).

Diagrams
4.1 Meet-me conference without subconferencing
This sequence illustrates a pre-arranged meet-me conference for a specified time period. During this timeslot parties can
'call in to' the meet-me conference by dialling a special number.
For each participant joining the conference, the application can decide to accept the participant in to the conference.
The application can also be notified when parties are leaving the conference.

1: The application creates a new object to receive the callbacks from the conference call control manager.
2: The application reserves resources for some time in the future.
With this same method the application registers interest in the creation of the conference (e.g. when the first
party to joins the conference or at the specified start time, this is implementation dependant).
The reservation also includes the conference policy. One of the elements is whether joined parties must be
explicitly attached. If so, this is treated as an implicit joinMonitorReq.
3: The conference is created.
4: The message is forwarded to the application.

5: The application creates an object to receive the call back messages from the conference call.
6: The application also requests to be notified when parties leave the conference.
7: The application is notified of the first party that joined the conference.
8: When the party is allowed to join the conference, the party is added.
Alternatively, the party could have been rejected with a releaseCallLeg.
9: A new party joins the conference and the application is notified.
10: The message is forwarded to the application.
11: This party also is allowed into the conference by attaching the leg.
12: A party leaves the conference.
13: The message is forwarded to the application.
14: The application decides to release the entire conference.
4.2 Non-add hoc add-on with subconferencing
This sequence illustrates a prearranged add-on conference. The end user that initiates the call, communicates with the
conference application via a web interface (not shown). By dragging and dropping names from the addressbook, the
end-user adds parties to the conference.
Also via the web-interface, the end-user can group parties in subconferences. Only parties in the same subconference
can talk to each other.

1: The application creates a new interface to receive the callbacks from the conference call.
2: The application initiates the conference. There has been no prior resource reservation, so there is a chance that
no resources are available when parties are added to the conference.
The conferenceCall interface object is returned.
3: Together with the conference a subconference is implicitly created.
However, the subconference is not returned as a result of the createConference, therefore the application uses
this method to get the subconference.
4: The application creates a new IpAppCallLeg interface.
5: The application adds the first party to the subconference. This process is repeated for all 4 parties. Note that in
the following not all steps are shown.
6: The gateway creates a new IpCallLeg interface.
7: The application adds parties to the subconference.
8: The application adds parties to the subconference.
9: The application adds parties to the subconference.
10: When a party A answers the application is notified.
We assume that all parties answer. This happens in the same way as for party A and is not shown in the
following.
11: The message is forwarded to the application.
ETSI

12 ETSI ES 204 915-4-5 V1.1.1 (2008-05)
12: The application decides to split the conference. Party C and D are indicated in the message.
The gateway will create a new subconference and move party C and D to the new subconference.
The configuration is A and B are in speech, C & D are in speech. There is no bearer connection between the
two subconferences.
13: The application moves one of the legs from the second subconference back to the first. The configuration now
is A, B and C are in speech configuration. D is alone in its own subconference.
14: The second subconference is released. Since party D was in this subconference, this callleg is also released.
This leaves one subconference with A, B and C.
4.3 Non-addhoc add-on multimedia
This sequence illustrates a prearranged add-on multi-media conference. The end user that initiates the call,
communicates with the conference application via a web interface (not shown). By dragging and dropping names from
the addressbook, the end-user adds parties to the conference.
Also via the web-interface, the end-user can do things that normally the chair would be able to do, e.g. determine who
has the floor (e.g. whose video is being broadcast to the other participants) or inspect the video of participants who do
not have the floor (e.g. to see how they react to the current speaker).

2: When the user selects the appropriate option in the web interface, the application will create a conference
without resource reservation. The policy for video is set to 'chairperson switched.
3: The application requests the subconference that was implicitly created together with the conference.
4: The application creates a new IpAppCallLeg interface.
5: The application adds the first party to the subconference. This process is repeated for all 4 parties. Note that in
the following not all steps are shown.
6: The gateway creates a new IpCallLeg interface.
7: The application creates a new IpAppCallLeg interface.
8: The application adds parties to the conference and monitors on success.

1 Scope
The present document is part 4, sub-part 5 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 Conference Call Control Service Capability Feature (SCF) aspects of the interface.
All aspects of the Conference 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).

Diagrams
4.1 Meet-me conference without subconferencing
This sequence illustrates a pre-arranged meet-me conference for a specified time period. During this timeslot parties can
'call in to' the meet-me conference by dialling a special number.
For each participant joining the conference, the application can decide to accept the participant in to the conference.
The application can also be notified when parties are leaving the conference.

2: The application reserves resources for some time in the future.
With this same method the application registers interest in the creation of the conference (e.g. when the first
party to joins the conference or at the specified start time, this is implementation dependant).
The reservation also includes the conference policy. One of the elements is whether joined parties must be
explicitly attached. If so, this is treated as an implicit joinMonitorReq.
3: The conference is created.
4: The message is forwarded to the application.

6: The application also requests to be notified when parties leave the conference.
7: The application is notified of the first party that joined the conference.
8: When the party is allowed to join the conference, the party is added.
Alternatively, the party could have been rejected with a releaseCallLeg.
9: A new party joins the conference and the application is notified.
10: The message is forwarded to the application.
11: This party also is allowed into the conference by attaching the leg.
12: A party leaves the conference.
13: The message is forwarded to the application.
14: The application decides to release the entire conference.
4.2 Non-add hoc add-on with subconferencing
This sequence illustrates a prearranged add-on conference. The end user that initiates the call, communicates with the
conference application via a web interface (not shown). By dragging and dropping names from the addressbook, the
end-user adds parties to the conference.
Also via the web-interface, the end-user can group parties in subconferences. Only parties in the same subconference
can talk to each other.

1: The application creates a new interface to receive the callbacks from the conference call.
2: The application initiates the conference. There has been no prior resource reservation, so there is a chance that
no resources are available when parties are added to the conference.
The conferenceCall interface object is returned.
3: Together with the conference a subconference is implicitly created.
However, the subconference is not returned as a result of the createConference, therefore the application uses
this method to get the subconference.
4: The application creates a new IpAppCallLeg interface.
5: The application adds the first party to the subconference. This process is repeated for all 4 parties. Note that in
the following not all steps are shown.
6: The gateway creates a new IpCallLeg interface.
7: The application adds parties to the subconference.
8: The application adds parties to the subconference.
9: The application adds parties to the subconference.
10: When a party A answers the application is notified.
We assume that all parties answer. This happens in the same way as for party A and is not shown in the
following.
11: The message is forwarded to the application.
ETSI
---------------------- Page: 11 ----------------------
12 Final draft ETSI ES 204 915-4-5 V1.1.1 (2008-02)
12: The application decides to split the conference. Party C and D are indicated in the message.
The gateway will create a new subconference and move party C and D to the new subconference.
The configuration is A and B are in speech, C & D are in speech. There is no bearer connection between the
two subconferences.
13: The application moves one of the legs from the second subconference back to the first. The configuration now
is A, B and C are in speech configuration. D is alone in its own subconference.
14: The second subconference is released. Since party D was in this subconference, this callleg is also released.
This leaves one subconference with A, B and C.
4.3 Non-addhoc add-on multimedia
This sequence illustrates a prearranged add-on multi-media conference. The end user that initiates the call,
communicates with the conference application via a web interface (not shown). By dragging and dropping names from
the addressbook, the end-user adds parties to the conference.
Also via the web-interface, the end-user can do things that normally the chair would be able to do, e.g. determine who
has the floor (e.g. whose video is being broadcast to the other participants) or inspect the video of participants who do
not have the floor (e.g. to see how they react to the current speaker).

2: When the user selects the appropriate option in the web interface, the application will create a conference
without resource reservation. The policy for video is set to 'chairperson switched.
3: The application requests the subconference that was implicitly created together with the conference.
4: The application creates a new IpAppCallLeg interface.
5: The application adds the first party to the subconference. This process is repeated for all 4 parties. Note that in
the following not all steps are shown.

4.2 Non-add hoc add-on with subconferencing
This sequence illustrates a prearranged add-on conference. The end user that initiates the call, communicates with the
conference application via a web interface (not shown). By dragging and dropping names from the addressbook, the
end-user adds parties to the conference.
Also via the web-interface, the end-user can group parties in subconferences. Only parties in the same subconference
can talk to each other.

1: The application creates a new interface to receive the callbacks from the conference call.
2: The application initiates the conference. There has been no prior resource reservation, so there is a chance that
no resources are available when parties are added to the conference.
The conferenceCall interface object is returned.
3: Together with the conference a subconference is implicitly created.
However, the subconference is not returned as a result of the createConference, therefore the application uses
this method to get the subconference.
4: The application creates a new IpAppCallLeg interface.
5: The application adds the first party to the subconference. This process is repeated for all 4 parties. Note that in
the following not all steps are shown.
6: The gateway creates a new IpCallLeg interface.
7: The application adds parties to the subconference.
8: The application adds parties to the subconference.
9: The application adds parties to the subconference.
10: When a party A answers the application is notified.
We assume that all parties answer. This happens in the same way as for party A and is not shown in the
following.
11: The message is forwarded to the application.

12: The application decides to split the conference. Party C and D are indicated in the message.
The gateway will create a new subconference and move party C and D to the new subconference.
The configuration is A and B are in speech, C & D are in speech. There is no bearer connection between the
two subconferences.
13: The application moves one of the legs from the second subconference back to the first. The configuration now
is A, B and C are in speech configuration. D is alone in its own subconference.
14: The second subconference is released. Since party D was in this subconference, this callleg is also released.
This leaves one subconference with A, B and C.
4.3 Non-addhoc add-on multimedia
This sequence illustrates a prearranged add-on multi-media conference. The end user that initiates the call,
communicates with the conference application via a web interface (not shown). By dragging and dropping names from
the addressbook, the end-user adds parties to the conference.
Also via the web-interface, the end-user can do things that normally the chair would be able to do, e.g. determine who
has the floor (e.g. whose video is being broadcast to the other participants) or inspect the video of participants who do
not have the floor (e.g. to see how they react to the current speaker).
