SIST ES 202 504-12 V1.1.1:2008 is the Slovenian standard identical to ETSI ES 202 504-12 V1.1.1. It specifies the Open Service Access (OSA) Parlay X Web Services interface for Multimedia Conference, aimed at application developers and implementers who use OSA APIs to create and manage conference calls.

The document defines the web service contract in a way that can be implemented and tested: namespaces, data types, sequence diagrams, operations, fault handling, service policies, and the WSDL binding.

What does SIST ES 202 504-12 V1.1.1:2008 specify?

SIST ES 202 504-12 V1.1.1:2008 specifies the Multimedia Conference Web Service in the Parlay X 3 OSA family. It describes how an application creates a conference context, invites and disconnects participants, queries conference and participant status, and ends a conference.

The document is organized into these main clauses:

• Scope and references
• Definitions and abbreviations
• Detailed service description
• Namespaces
• Sequence diagrams
• XML Schema data type definition
• Web Service interface definition
• Fault definitions
• Service policies

It also has two annexes.

Annex	What it covers
Annex A, normative	WSDL for Multimedia Conference
Annex B, informative	Bibliography

The service uses these namespaces:

• Interface namespace: http://www.csapi.org/wsdl/parlayx/multimedia_conference/v3_1
• Data type namespace: http://www.csapi.org/schema/parlayx/multimedia_conference/v3_1

Clause 5 also states that the xsd prefix refers to XML Schema datatypes.

What are the key requirements of SIST ES 202 504-12 V1.1.1:2008?

SIST ES 202 504-12 V1.1.1:2008 defines a conference as a shared context that participants can join and leave, with optional media streams for audio and video. In practice, the application creates the conference first, then manages participants and conference status through web service operations.

Conference creation and lifecycle

Clause 4 and clause 8.1.1 say that createConference creates a new conference with no connected participants and returns a callSessionIdentifier. The conference becomes Active when the first participant connects, and the duration starts from that point. This matters because the application must treat creation, activation, and billing or timeout tracking as separate stages.

Conference end conditions

The service supports several ways to end a conference. Clause 4 and clause 8.1.1 state that the conference can end when the application calls endConference, when the conference owner disconnects, when the last participant leaves, or when the configured maximum duration is reached. If maximumDuration is present, it defines the end condition; if conferenceOwner is present without maximumDuration, the owner disconnect can end the conference. This matters for call control and for deciding who can terminate the session.

Participant control

Clause 8.1.4 and clause 8.1.5 define participant management. inviteParticipant adds a new participant and alerts the user, while disconnectParticipant removes a participant from the conference. The service can reject an invitation if the conference has reached the maximum number of participants. In practice, implementers need to enforce capacity limits and handle user alerting and disconnection cleanly.

Status queries

Clause 8.1.2, 8.1.6 and 8.1.7 define the status retrieval operations. getConferenceInfo returns the conference state, and getParticipantInfo returns the state of one participant. getParticipants returns the status of every participant, including participants already disconnected. This is useful for user interfaces, monitoring, and audit or reporting functions.

Conference setup parameters

Clause 8.1.1.1 defines the creation request fields: conferenceType, conferenceDescription, charging, maximumDuration, maximumNumberOfParticipants, and conferenceOwner. The selected conference behavior depends on which optional parts are present. That means the application must decide at setup time whether the conference is owner-driven, duration-driven, or ended by the last participant disconnecting.

Faults and service policies

Clause 9 and clause 10 define the policy limits and errors. The service can raise POL0240 for too many participants and POL0242 when the maximum duration is exceeded. The service policies are MaximumDuration, MaximumParticipants, and ChargingSupported. In practice, these policy values tell the application what limits to respect before it sends a request.

Media handling

Clause 4 notes that the conference can use multiple media streams, including audio and video, with in, out, or bidirectional direction. It also points to addMediaForParticipants and deleteMediaForParticipants in the Audio Call web service for media control. That means this document covers conference control, while media changes may be delegated to the related Audio Call service.

What terms does SIST ES 202 504-12 V1.1.1:2008 define?

ConferenceStatus is the conference state enumeration with Initial, Active, and Terminated, showing whether the conference is waiting, running, or ended.

ConferenceInfo is the structure that carries the conference status and related metadata such as start time, duration, owner, participant count, limits, and the call session identifier.

ParticipantInfo is the structure that describes one participant, including the participant identifier, media information, join time, and current status.

ParticipantStatus is the participant state enumeration with Invited, Connected, and Disconnected.

callSessionIdentifier is the identifier returned for the created conference call and used in later requests to refer to that conference.

conferenceOwner is the address of the owner participant, used to control the conference end condition or to support billing-related handling.

Who uses SIST ES 202 504-12 V1.1.1:2008?

SIST ES 202 504-12 V1.1.1:2008 is used by application developers who build services on top of OSA APIs and need to create or manage conference calls through a standardized interface. It is also used by telecom service implementers and platform vendors that expose the MultimediaConference service.

Test and quality teams use the sequence diagrams, operation descriptions, faults, and service policies to verify conference setup, participant control, status queries, and termination behavior. Billing and service operations teams can also use the conference owner and maximum duration concepts when they need call control tied to service policy.

What changed in SIST ES 202 504-12 V1.1.1:2008 from the previous edition?

SIST ES 202 504-12 V1.1.1:2008 is the Slovene version of ES 202 504-12 V1.1.1 and is equivalent to 3GPP TS 29.199-12 V7.1.0 (Release 7). The foreword also states that it is part 12 of the Parlay X 3.0 set of specifications and that it was defined jointly by ETSI, The Parlay Group, and 3GPP.

Which standards are used with SIST ES 202 504-12 V1.1.1:2008?

The document relies on W3C Recommendation XML Schema Part 2: Datatypes for the xsd data types used in the schema and message definitions. It also depends on ETSI ES 202 504-1, Open Service Access (OSA); Parlay X Web Services; Part 1: Common (Parlay X 3) for shared terms, abbreviations, and common framework elements.

What does the SIST ES 202 504-12 V1.1.1:2008 document contain?

The document contains a service description, sequence diagrams for conference setup and termination scenarios, XML Schema data type definitions, and a web service interface with operation-level message structures. It also includes fault definitions for policy and service errors, plus service policy parameters that set limits for duration, participant count, and charging support.

Annex A provides the normative WSDL representation in accompanying text files, which is the implementation-facing contract for tooling and code generation. Annex B gives the bibliography for related background material.

4 Detailed service description
The Multimedia Conferencing is a simple Web Service that allows the creation of a multimedia conference and the
dynamic management of the participants involved.
The underlying model of the service is based on the following entities:
• Conference: a "context" (uniquely identified) to which participants can be added/removed.
• Participant: each of the parties involved in the conference. There may exist a participant that is also the
"owner" of the conference, i.e. the user who can end the call and/or be the reference user for billing purposes.
• Media: the conference can utilize multiple media streams to support the participants' communication. In
particular both audio and video streams are available, including the specific stream direction (i.e. in, out,
bidirectional).
NOTE: A call session allows the application to avail of other web service features that can add value to the
created call session. For example the Audio Call web service can provide multimedia message delivery to
call participants in the call session (playXxxMessage operation) and furthermore control of the media
streams for the call participants thus

4 Detailed service description
The Multimedia Conferencing is a simple Web Service that allows the creation of a multimedia conference and the
dynamic management of the participants involved.
The underlying model of the service is based on the following entities:
• Conference: a "context" (uniquely identified) to which participants can be added/removed.
• Participant: each of the parties involved in the conference. There may exist a participant that is also the
"owner" of the conference, i.e. the user who can end the call and/or be the reference user for billing purposes.
• Media: the conference can utilize multiple media streams to support the participants' communication. In
particular both audio and video streams are available, including the specific stream direction (i.e. in, out,
bidirectional).
NOTE: A call session allows the application to avail of other web service features that can add value to the
created call session. For example the Audio Call web service can provide multimedia message delivery to
call participants in the call session (playXxxMessage operation) and furthermore control of the media
streams for the call participants thus enabling
