1 Scope
The present document is part 12 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 Charging Service Capability Feature (SCF) aspects of the interface. All aspects of
the Charging 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
The process by which this task is accomplished is through the use of object modelling techniques described by the
Unified Modelling Language (UML).

4 Charging SCF
The following clauses describe each aspect of the Charging Service Capability Feature (SCF).
The order is as follows:
• The Sequence diagrams give the reader a practical idea of how each of the SCF is implemented.
• The Class relationships clause show how each of the interfaces applicable to the SCF, relate to one another.
• The Interface specification clause describes in detail each of the interfaces shown within the Class diagram
part.
• The State Transition Diagrams (STD) show the transition between states in the SCF. The states and transitions
are well-defined; either methods specified in the Interface specification or events occurring in the underlying
networks cause state transitions.
• The Data Definitions clause show a detailed expansion of each of the data types associated with the methods
within the classes. Note that some data types are used in other methods and classes and are therefore defined
within the Common Data types part of the present document.
4.1 General requirements on support of methods
An implementation of this API which supports or implements a method described in the present document, shall
support or implement the functionality described for that method, for at least one valid set of values for the parameters
of that method.
Where a method is not supported by an implementation of a Service interface, the exception
P_METHOD_NOT_SUPPORTED shall be returned to any call of that method.
Where a method is not supported by an implementation of an Application interface, a call to that method shall be
possible, and no exception shall be returned.
5 Sequence Diagrams
5.1 Reservation / payment in parts
The sequence diagram illustrates how to request a reservation and how to charge a user from the reserved amount, for
instance to charge a user for a streamed video which lasts 10 minutes and costs a total of $2.00. The operations and
interfaces that do not provide rating are employed throughout this sequence diagram.
We assume the application has already discovered the Charging SCF. As a result, the application received an object
reference pointing to an object that implements the IpChargingManager interface.
The operations which handle units are used exactly the same, except that the amount of application usage is indicated
instead of a price.

1: The application creates a local object implementing the IpAppChargingSession interface. This object will
receive response messages from the IpChargingSession object.
2: The application opens a charging session, a reference to a new or existing object implementing
IpChargingSession is returned together with a unique session ID.
3: In this case a new object is used.
4: The application requests the reservation of $2.00.

5: Assuming the criteria for requesting a reservation are met (the application provider has permission to charge
the requested amount, the charged user has agreed to pay the requested amount), the amount is reserved in the
session. At this point, the application provider knows that the network operator will accept later debit requests
up to the reserved amount. So, the application may start serving the user, for instance by sending the video
stream.
6: The successful reservation is reported back to the application.
After half of the video has been sent to the user, the application may choose to capture half of the price already:
7: The application requests to debit $1.00 from the reservation.
8: The successful debit is reported back to the application.
9: The acknowledge is forwarded to the application.
10: The application checks if the remaining lifetime of the reservation will cover the remaining 5 minutes of video.
Let us assume, it does not.
11: The application asks the IpChargingSession object to extend the lifetime of the reservation.
12: Assuming that the application provider is allowed to keep reservations open for longer than 10 minutes, the
extendLifeTimeReq() will be honoured and confirmed properly.
13: The confirmation is forwarded to the application.
14: When the complete video has been transmitted to the user without errors, the application charges another
$1.00.
15: The IpChargingSession object acknowledges the successful debit at the IpAppChargingSession callback
object.
16: The IpAppChargingSession object forwards the acknowledge to the application.
17: Since the service is complete, the application frees all resources associated with the reservation and session.
5.2 Immediate Charge
This sequence diagram illustrates how immediate charging is used. Assume a WAP gateway that charges the user $0.01
per requested URL. Since it is acceptable to loose one tick worth $0.01, no prior reservations are made. The WAP
gateway sends an immediate debit for each requested URL, and should a payment have as result failure, the user is
disconnected.
The operations which handle units are used exactly the same, except that the amount of application usage is indicated
instead of a price.

1: The application creates a local object implementing the IpAppChargingSession interface. This object will
receive response messages from the IpChargingSession object.
2: The application orders the creation of a session. No new object is created for the charging session handling in
this example implementation.
3: The application requests to charge the user $0.01.
4: The payment is acknowledged.
5: The acknowledgement is forwarded in the application.
6: The application requests to charge the user $0.01.
7: The payment is reported to fail.
8: The failure report is forwarded in the application.
(repeat steps 3 - 5 and 6 - 8 as long as you want to in any order you want to)
9: The application releases the session.
