1 Scope
The present document is part 4, sub-part 1 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 common definitions used by the Call Control Service Capability Features (SCF).

4 Call Control SCF
Four flavours of call control APIs are specified in ES 202 915, Parlay 4. Three of these have been included in 3GPP
Release 5. These are the Generic Call Control (GCC), the Multi-Party Call Control (MPCC) and the Multi-Media Call
Control (MMCC). The generic call control is the same API as was already present in the previous specification for
3GPP Release 99 (TS 129 198 V3). Multi-Party Call Control was introduced in the Release 4 specifications, and
Multi-Media Call Control is introduced in Release 5. All four have been included in ETSI ES 201 915, Parlay 3.
The joint work between 3GPP CN5, ETSI SPAN and the Parlay Call Control Working group with collaboration from
JAIN has been focussed on the Multi-party and Multi-Media call control APIs. A number of improvements on call
control functionality have been made and are reflected in these APIs. For this it was necessary to break the inheritance
that previously existed between Generic and Multi-party call control.
The joint call control group has furthermore decided that the multi-party call control is to be considered as the future
base call control family and the technical work will not be continued on Generic Call control. Errors or technical flaws
will of course be corrected.

4.1 Call Model Description
The call model used for the Call Control SCFs has the following objects.
• A call object. A call is a relation between a number of parties. The call object relates to the entire call view
from the application. E.g. the entire call will be released when a release is called on the call. Note that different
applications can have different views on the same physical call, e.g. one application for the originating side
and another application for the terminating side. The applications will not be aware of each other, all
'communication' between the applications will be by means of network signalling. The API currently does not
specify any feature interaction mechanisms.
• A call leg object. The leg object represents a logical association between a call and an address. The
relationship includes at least the signalling relation with the party. The relation with the address is only made
when the leg is routed. Before that the leg object is IDLE and not yet associated with the address.
• An address. The address logically represents a party in the call.
• A terminal. A terminal is the end-point of the signalling and/or media for a party. This object type is currently
not addressed.
The call object is used to establish a relation between a number of parties by creating a leg for each party within the
call.
Associated with the signalling relationship represented by the call leg, there may also be a bearer connection (e.g. in the
traditional voice only networks) or a number (zero or more) of media channels (in multi-media networks).
A leg can be attached to the call or detached from the call. When the leg is attached, this means that media or bearer
channels related to the legs are connected to the media or bearer channels of the other legs that are attached to the same
call. I.e. only legs that are attached can 'speak' to each other. A leg can have a number of states, depending on the
signalling received from or sent to the party associated with the leg. Usually there is a limit to the number of legs that
are in being routed (i.e. the connection is being established) or connected to the call (i.e. the connection is established).
Also, there usually is a limit to the number of legs that can be simultaneously attached to the same call.
Some networks distinguish between controlling and passive legs. By definition the call will be released when the
controlling leg is released. All other legs are called passive legs. There can be at most one controlling leg per call.
However, there is currently no way the application can influence whether a Leg is controlling or not.
There are two ways for an application to get the control of a call. The application can request to be notified of calls that
meet certain criteria. When a call occurs in the network that meets these criteria, the application is notified and can
control the call. Some legs will already be associated with the call in this case. Another way is to create a new call from
the application.
4.2 Structure of Call Control SCF Documentation
Each of the Call Control SCFs is specified under the following headings:
• The Sequence diagrams give the reader a practical idea of how each of the SCF is implemented.
• The Class relationships clause shows 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 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 ES 202 915-2.

4.3 General requirements on support of methods
An implementation of one of the call control APIs which supports or implements a method described in one of the
sub-parts of ES 202 915-4, 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 The Service Interface Specifications
5.1 Interface Specification Format
This clause defines the interfaces, methods and parameters that form a part of the API specification. The Unified
Modelling Language (UML) is used to specify the interface classes. The general format of an interface specification is
described below.
5.1.1 Interface Class
This shows a UML interface class description of the methods supported by that interface, and the relevant parameters
and types. The Service and Framework interfaces for enterprise-based client applications are denoted by classes with
name Ip. The callback interfaces to the applications are denoted by classes with name IpApp. For the
interfaces between a Service and the Framework, the Service interfaces are typically denoted by classes with name
IpSvc, while the Framework interfaces are denoted by classes with name IpFw
5.1.2 Method descriptions
Each method (API method "call") is described. Both synchronous and asynchronous methods are used in the API.
Asynchronous methods are identified by a 'Req' suffix for a method request, and, if applicable, are served by
asynchronous methods identified by either a 'Res' or 'Err' suffix for method results and errors, respectively. To handle
responses and reports, the application or service developer must implement the relevant IpApp or IpSvc
interfaces to provide the callback mechanism.
5.1.3 Parameter descriptions
Each method parameter and its possible values are described. Parameters described as 'in' represent those that must have
a value when the method is called. Those described as 'out' are those that contain the return result of the method when
the method returns.
5.1.4 State Model
If relevant, a state model is shown to illustrate the states of the objects that implement the described interface.
5.2 Base Interface
5.2.1 Interface Class IpInterface
All application, framework and service interfaces inherit from the following interface. This API Base Interface does not
provide any additional methods.

5.3 Service Interfaces
5.3.1 Overview
The Service Interfaces provide the interfaces into the capabilities of the underlying network - such as call control, user
interaction, messaging, mobility and connectivity management.
The interfaces that are implemented by the services are denoted as 'Service Interface'. The corresponding interfaces that
must be implemented by the application (e.g. for API callbacks) are denoted as 'Application Interface'.

All service interfaces inherit from the following interface.
