ISO/IEC 20117:2004

Information technology — Telecommunications and information exchange between systems — Private Integrated Services Network — Inter-exchange signalling protocol — Message centre monitoring and mailbox identification supplementary services

ISO/IEC 20117:2004 specifies the signalling protocol for the support of the Message Centre Monitoring supplementary service (SS-MCM) as well as the Mailbox Identification supplementary service (SS-MID) at the Q reference point between Private Integrated services Network eXchanges (PINXs) connected together within a Private Integrated Services Network (PISN). The supplementary service MCM enables a Served User to get informed by a Message Centre about the status and status changes of messages stored in that Served Users Mailbox. The supplementary service MID enables a Message Centre to identify a specific mailbox of a Served User in case the Served User has more than one mailbox within the Message Centre. In addition SS-MID enables a Served User to authenticate himself/herself at a specific mailbox located within the Messages Centre. The Q reference point is defined in ISO/IEC 11579-1. Service specifications are produced in three stages and according to the method specified in ETS 300 387. This International Standard contains the stage 3 specification for the Q reference point and satisfies the requirements identified by the stage 1 and stage 2 specifications in ISO/IEC 20116. The signalling protocol for SS-MCM and SS-MID uses certain aspects of the generic procedures for the control of supplementary services specified in ISO/IEC 11582. ISO/IEC 20117:2004 also specifies additional signalling protocol requirements for the support of interactions at the Q reference point between SS-MCM as well as SS-MID and other supplementary services and ANFs.

Foreword
ISO (the International Organization for Standardization) and IEC (the International Electrotechnical
Commission) form the specialized system for worldwide standardization. National bodies that are members of
ISO or IEC participate in the development of International Standards through technical committees
established by the respective organization to deal with particular fields of technical activity. ISO and IEC
technical committees collaborate in fields of mutual interest. Other international organizations, governmental
and non-governmental, in liaison with ISO and IEC, also take part in the work. In the field of information
technology, ISO and IEC have established a joint technical committee, ISO/IEC JTC 1.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of the joint technical committee is to prepare International Standards. Draft International
Standards adopted by the joint technical committee are circulated to national bodies for voting. Publication as
an International Standard requires approval by at least 75 % of the national bodies casting a vote.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. ISO and IEC shall not be held responsible for identifying any or all such patent rights.
ISO/IEC 20117 was prepared by ECMA (as ECMA-347) and was adopted, under a special “fast-track
procedure”, by Joint Technical Committee ISO/IEC JTC 1, Information technology, in parallel with its approval
by national bodies of ISO and IEC.

ISO/IEC 20117:2004(E)
Introduction
This International Standard is one of a series defining services and signalling protocols applicable to Private
Integrated Services Networks (PISNs). The series uses ISDN concepts as developed by ITU-T and conforms
to the framework of International Standards for Open Systems Interconnection as defined by ISO/IEC.
This International Standard specifies the signalling protocol for use at the Q reference point in support of the
Message Centre Monitoring supplementary service as well as the Mailbox Identification supplementary
service. The protocol defined in this International Standard forms part of the PSS1 protocol (informally known
as QSIG).
SS-MCM is based on SS-MWI and includes its entire functionality. The interoperability with SS-MWI is
therefore guaranteed. Compared to SS-MWI, SS-MCM offers an enhanced functionality for monitoring status
changes of messages stored in the Served User's Mailbox as follows:
• individual activation and deactivation for the monitoring of messages of different Message Type(s) within
the Mailbox as well as interrogation of the actual SS-MCM configuration;
• retrieval of information about all messages (i.e. new and retrieved messages) in the mailbox independent
of the Message Status;
• request of detailed updated information about messages stored in the mailbox.
This International Standard is based upon the practical experience of ECMA member companies and the
results of their active and continuous participation in the work of ISO/IEC JTC1, ITU-T, ETSI and other
international and national standardization bodies. It represents a pragmatic and widely based consensus.

INTERNATIONAL STANDARD ISO/IEC 20117:2004(E)

Information technology — Telecommunications and information
exchange between systems — Private Integrated Services
Network — Inter-exchange signalling protocol — Message
centre monitoring and mailbox identification supplementary
services
1 Scope
This International Standard specifies the signalling protocol for the support of the Message Centre Monitoring
supplementary service (SS-MCM) as well as the Mailbox Identification supplementary service (SS-MID) at the
Q reference point between Private Integrated services Network eXchanges (PINXs) connected together within
a Private Integrated Services Network (PISN).
The supplementary service MCM enables a Served User to get informed by a Message Centre about the
status and status changes of messages stored in that Served Users Mailbox.
The supplementary service MID enables a Message Centre to identify a specific mailbox of a Served User in
case the Served User has more than one mailbox within the Message Centre. In addition SS-MID enables a
Served User to authenticate himself/herself at a specific mailbox located within the Messages Centre.
The Q reference point is defined in ISO/IEC 11579-1.
Service specifications are produced in three stages and according to the method specified in ETS 300 387.
This International Standard contains the stage 3 specification for the Q reference point and satisfies the
requirements identified by the stage 1 and stage 2 specifications in ISO/IEC 20116.
The signalling protocol for SS-MCM and SS-MID uses certain aspects of the generic procedures for the
control of supplementary services specified in ISO/IEC 11582.
This International Standard also specifies additional signalling protocol requirements for the support of
interactions at the Q reference point between SS-MCM as well as SS-MID and other supplementary services
and ANFs.
NOTE Additional interactions that have no impact on the signalling protocol at the Q reference point can be found in
the relevant stage 1 specifications.
2 Conformance
In order to conform to this International Standard, a PINX shall satisfy the requirements identified in the
Protocol Implementation Conformance Statement (PICS) proforma in Annex A.
Conformance to this International Standard includes conforming to those clauses that specify protocol
interactions between SS-MCM as well as SS-MID and other supplementary services and ANFs for which
signalling protocols at the Q reference point are supported in accordance with the stage 3 standards
concerned.

6 Signalling protocol for the support of SS-MCM
6.1 SS-MCM description
The supplementary service MCM enables a Message Centre to inform a registered Served User about the
status and status changes of messages stored in the Served User’s Mailbox. This can be due to the arrival of
New Messages or due to the change of the Message Status of stored messages (e.g. retrieval or deletion of
messages). Additionally the Served User can request the current status of the messages in the Mailbox from
the Message Centre.
If there are new messages for the Served User stored in the mailbox, a Message Waiting Signal may be set at
the Served User’s terminal.
Additionally a Served User might activate, deactivate or interrogate Message Centre Monitoring individually for
the different Message Types.
6.2 SS-MCM operational requirements
6.2.1 Requirements on a Message Centre PINX
Call establishment procedures for the incoming and outgoing side of an inter-PINX link and call release
procedures, as specified in ISO/IEC 11572, shall apply.
Generic procedures for call-independent control (connection-oriented) of supplementary services, as specified
in ISO/IEC 11582 for an Originating PINX and for a Terminating PINX, shall apply.
