Foreword
This ETSI Standard (ES) has been produced by ETSI Technical Committee Telecommunications and Internet
converged Services and Protocols for Advanced Networking (TISPAN), and is now submitted for the ETSI standards
Membership Approval Procedure.
The present document is part 8 of a multi-part deliverable covering Open Service Access (OSA); Application
Programming Interface (API), as identified below. The API specification (ES 204 915) is structured in the following
parts:
Part 1: "Overview";
Part 2: "Common Data Definitions";
Part 3: "Framework";
Part 4: "Call Control";
Part 5: "User Interaction SCF";
Part 6: "Mobility SCF";
Part 7: "Terminal Capabilities SCF";
Part 8: "Data Session Control SCF";
Part 9: "Generic Messaging SCF";
Part 10: "Connectivity Manager SCF";
Part 11: "Account Management SCF";
Part 12: "Charging SCF";
Part 13: "Policy Management SCF";
Part 14: "Presence and Availability Management SCF";
Part 15: "Multi-Media Messaging SCF";
Part 16: "Service Broker SCF".
The present document has been defined jointly between ETSI, The Parlay Group (http://www.parlay.org) and the 3GPP,
in co-operation with a number of JAIN™ Community (http://www.java.sun.com/products/jain) member companies.
The present document forms part of the Parlay 6.0 set of specifications.
The present document is equivalent to 3GPP TS 29.198-8 V7.0.0 (Release 7).

1 Scope
The present document is part 8 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 Data Session Control Service Capability Feature (SCF) aspects of the interface. All
aspects of the Data Session 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.
The process by which this task is accomplished is through the use of object modelling techniques described by the
Unified Modelling Language (UML).

4 Data Session Control SCF
The Data Session control network service capability feature consists of two interfaces:
1) Data Session manager, containing management functions for data session related issues;
2) Data Session, containing methods to control a session.
A session can be controlled by one Data Session Manager only. Data Session Manager can control several sessions.

NOTE: The term "data session" is used in a broad sense to describe a data connection/session. For example, it
comprises a PDP context in GPRS.

Figure 1: Data Session control interfaces usage relationship
The Data Session Control service capability features are described in terms of the methods in the Data Session Control
interfaces. Table 1 gives an overview of the Data Session Control methods and to which interfaces these methods
belong.

1 Scope
The present document is part 8 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 Data Session Control Service Capability Feature (SCF) aspects of the interface. All
aspects of the Data Session 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.
The process by which this task is accomplished is through the use of object modelling techniques described by the
Unified Modelling Language (UML).
