1 Scope
The present document is part 4, sub-part 2 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 Generic Call Control Service Capability Feature (SCF) aspects of the interface. All
aspects of the Generic 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 Generic Call Control Service Sequence Diagrams
4.1 Additional Callbacks
The following sequence diagram shows how an application can register two call back interfaces for the same set of
events. If one of the call backs can not be used, e.g. because the application crashed, the other call back interface is used
instead.
first instance : (Logical : IpAppCallControlManager second instance : : IpAppCal lControlMan ager : IpCallControlManag er
View::IpAppLogic) (Logic.
1: new()
2: enableCallNotification( )
3: new()
4: enableCallNotification( )
5: callEventNotify(  )
6: 'forward event'
7: "call Notify result: failure"
8: callEventNotify(  )
9: "forward event"
1: The first instance of the application is started on node 1. The application creates a new IpAppCallControlManager to
handle callbacks for this first instance of the logic.
2: The enableCallNotification is associated with an applicationID. The call control manager uses the applicationID to
decide whether this is the same application.
3: The second instance of the application is started on node 2. The application creates a new
IpAppCallControlManager to handle callbacks for this second instance of the logic.
4: The same enableCallNotification request is sent as for the first instance of the logic. Because both requests are
associated with the same application, the second request is not rejected, but the specified callback object is stored as an
additional callback.
5: When the trigger occurs one of the first instance of the application is notified. The gateway may have different
policies on how to handle additional callbacks, e.g., always first try the first registered or use some kind of round robin
scheme.
6: The event is forwarded to the first instance of the logic.
ETSI
10 ETSI ES 202 915-4-2 V1.2.1 (2003-08)
7: When the first instance of the application is overloaded or unavailable this is communicated with an exception to the
call control manager.
8: Based on this exception the call control manager will notify another instance of the application (if available).
9: The event is forwarded to the second instance of the logic.
4.2 Alarm Call
The following sequence diagram shows a 'reminder message', in the form of an alarm, being delivered to a customer as
a result of a trigger from an application. Typically, the application would be set to trigger at a certain time, however, the
application could also trigger on events.
: (Logical : IpAppCall : : : IpCall : : IpUICall
View::IpAppLogic) IpAppUICall IpCallControlManager IpAppUIManager
1: new()
2: createCall( )
3: new()
4: routeReq(    )
5: routeRes(  )
6: 'f orward ev ent'
7: createUICall()
8: new()
9: sendInf oReq(   )
10: sendInf oRes(  )
11: 'f orward ev ent'
12: release( )
13: release( )
1: This message is used to create an object implementing the IpAppCall interface.
2: This message requests the object implementing the IpCallControlManager interface to create an object
implementing the IpCall interface.
3: Assuming that the criteria for creating an object implementing the IpCall interface (e.g. load control values not
exceeded) is met it is created.
4: This message instructs the object implementing the IpCall interface to route the call to the customer destined to
receive the 'reminder message'
5: This message passes the result of the call being answered to its callback object.
ETSI
11 ETSI ES 202 915-4-2 V1.2.1 (2003-08)
6: This message is used to forward the previous message to the IpAppLogic.
7: The application requests a new UICall object that is associated with the call object.
8: Assuming all criteria are met, a new UICall object is created by the service.
9: This message instructs the object implementing the IpUICall interface to send the alarm to the customer's call.
10: When the announcement ends this is reported to the call back interface.
11: The event is forwarded to the application logic.
12: The application releases the UICall object, since no further announcements are required. Alternatively, the
application could have indicated P_FINAL_REQUEST in the sendInfoReq in which case the UICall object would have
been implicitly released after the announcement was played.
13: The application releases the call and all associated parties.
ETSI
12 ETSI ES 202 915-4-2 V1.2.1 (2003-08)
4.3 Application Initiated Call
The following sequence diagram shows an application creating a call between party A and party B. This sequence could
be done after a customer has accessed a Web page and selected a name on the page of a person or organisation to talk
to.
: (Logical : IpAppCall : : IpCall
View::IpAppLo. IpCallControlManager
1: new()
2: createCall( )
3: new()
4: routeReq(    )
5: routeRes(  )
6: 'forward event'
7: routeReq(    )
8: routeRes(  )
9: 'forward event'
10: deassignCall( )
1: This message is used to create an object implementing the IpAppCall interface.
2: This message requests the object implementing the IpCallControlManager interface to create an object
implementing the IpCall interface.
3: Assuming that the criteria for creating an object implementing the IpCall interface (e.g. load control values not
exceeded) is met, it is created.
4: This message is used to route the call to the A subscriber (origination). In the message the application request
response when the A party answers.
5: This message indicates that the A party answered the call.
6: This message forwards the previous message to the application logic.
ETSI
13 ETSI ES 202 915-4-2 V1.2.1 (2003-08)
7: This message is used to route the call to the B-party. Also in this case a response is requested for call answer or
failure.
8: This message indicates that the B-party answered the call. The call now has two parties and a speech connection is
automatically established between them.
9: This message is used to forward the previous message to the IpAppLogic.
10: Since the application is no longer interested in controlling the call, the application deassigns the call. The call will
continue in the network, but there will be no further communication between the call object and the application.
4.4 Call Barring 1
The following sequence diagram shows a call barring service, initiated as a result of a prearranged event being received
by the call control service. Before the call is routed to the destination number, the calling party is asked for a PIN code.
The code is accepted and the call is routed to the original called party.
: (Logical : IpAppCallControlManager : IpAppCall : : : IpCall : : IpUICall

ETSI
14 ETSI ES 202 915-4-2 V1.2.1 (2003-08)
1: This message is used by the application to create an object implementing the IpAppCallControlManager interface.
2: This message is sent by the application to enable notifications on new call events. As this sequence diagram depicts
a call barring service, it is likely that all new call events destined for a particular address or address range prompted for
a password before the call is allowed to progress. When a new call, that matches the event criteria set, arrives a message
(not shown) is directed to the object implementing the IpCallControlManager. Assuming that the criteria for creating an
object implementing the IpCall interface (e.g. load control values not exceeded) is met, other messages (not shown) are
used to create the call and associated call leg object.
3: This message is used to pass the new call event to the object implementing the IpAppCallControlManager interface.
4: This message is used to forward the previous message to the IpAppLogic.
5: This message is used by the application to create an object implementing the IpAppCall interface. The reference to
this object is passed back to the object implementing the IpCallControlManager using the return parameter of the
callEventNotify.
6: This message is used to create a new UICall object. The reference to the call object is given when creating the
UICall.
7: Provided all the criteria are fulfilled, a new UICall object is created.
8: The call barring service dialogue is invoked.
9: The result of the dialogue, which in this case is the PIN code, is returned to its callback object.
10: This message is used to forward the previous message to the IpAppLogic.
11: This message releases the UICall object.
12: Assuming the correct PIN is entered, the call is forward routed to the destination party.
13: This message passes the result of the call being answered to its callback object.
14: This message is used to forward the previous message to the IpAppLogic
15: When the call is terminated in the network, the application will receive a notification. This notification will always
be received when the call is terminated by the network in a normal way, the application does not have to request this
event explicitly.
16: The event is forwarded to the application.
17: The application must free the call related resources in the gateway by calling deassignCall.

4.5 Number Translation 1
The following sequence diagram shows a simple number translation service, initiated as a result of a prearranged event
being received by the call control service.
: (Logical : IpAppCallControlManager : IpAppCall : : IpCall
View::IpAppLo. IpCallControlManager
1: new()
2: enableCallNotification( )
3: callEventNotify(  )
4: 'forward event'
5: new()
6: 'translate number'
7: routeReq(    )
8: routeRes(  )
9: 'forward event'
10: deassignCall( )
1: This message is used by the application to create an object implementing the IpAppCallControlManager interface.
2: This message is sent by the application to enable notifications on new call events. As this sequence diagram depicts
a number translation service, it is likely that only new call events within a certain address range will be enabled. When a
new call, that matches the event criteria set in message 2, arrives a message (not shown) is directed to the object
implementing the IpCallControlManager. Assuming that the criteria for creating an object implementing the IpCall
interface (e.g. load control values not exceeded) is met, other messages (not shown) are used to create the call and
associated call leg object.
3: This message is used to pass the new call event to the object implementing the IpAppCallControlManager interface.
ETSI
16 ETSI ES 202 915-4-2 V1.2.1 (2003-08)
4: This message is used to forward message 3 to the IpAppLogic.
5: This message is used by the application to create an object implementing the IpAppCall interface. The reference to
this object is passed back to the object implementing the IpCallControlManager using the return parameter of message
3.
6: This message invokes the number translation function.
7: The returned translated number is used in message 7 to route the call towards the destination.
8: This message passes the result of the call being answered to its callback object
9: This message is used to forward the previous message to the IpAppLogic.
10: The application is no longer interested in controlling the call and therefore deassigns the call. The call will continue
in the network, but there will be no further communication between the call object and the application.

4.6 Number Translation 1 (with callbacks)
The following sequence diagram shows a simple number translation service, initiated as a result of a prearranged event
being received by the call control service.
For illustration, in this sequence the callback references are set explicitly. This is optional. All the callbacks references
can also be passed in other methods. From an efficiency point of view that is also the preferred method. The rest of the
sequences use that mechanism.
: (Logical : IpAppCallControlManager : IpAppCall : : IpCall
View::IpAppLogic) IpCallControlManager
1: new()
2: enableCallNotification( )
3: setCallback( )
4: callEventNotify(  )
5: 'forward event'
6: new()
7: setCallbackWithSessionID( )
8: 'translate number'
9: routeReq(    )
10: rout eRes(  )
11: 'forward event'
12: deassignCall( )
1: This message is used by the application to create an object implementing the IpAppCallControlManager interface.
2: This message is sent by the application to enable notifications on new call events. As this sequence diagram depicts
a number translation service, it is likely that only new call events within a certain address range will be enabled. When a
new call, that matches the event criteria set in message 2, arrives a message (not shown) is directed to the object
implementing the IpCallControlManager. Assuming that the criteria for creating an object implementing the IpCall
interface (e.g. load control values not exceeded) is met, other messages (not shown) are used to create the call and
associated call leg object.
ETSI
18 ETSI ES 202 915-4-2 V1.2.1 (2003-08)
3: This message sets the reference of the IpAppCallControlManager object in the CallControlManager. The
CallControlManager reports the callEventNotify to referenced object only for enableCallNotifications that do not have
an explicit IpAppCallControlManager reference specified in the enableCallNotification.
4: This message is used to pass the new call event to the object implementing the IpAppCallControlManager interface.
5: This message is used to forward message 4 to the IpAppLogic.
6: This message is used by the application to create an object implementing the IpAppCall interface.
7: This message is used to set the reference to the IpAppCall for this call.
8: This message invokes the number translation function.
9: The returned translated number is used in message 7 to route the call towards the destination.
10: This message passes the result of the call being answered to its callback object.
11: This message is used to forward the previous message to the IpAppLogic.
12: The application is no longer interested in controlling the call and therefore deassigns the call. The call will continue
