SIST ES 202 060-4 V1.1.1:2005 is the Slovenian standard adopted from ETSI ES 202 060-4 V1.1.1, published by SIST. It specifies the mapping between Digital Subscriber Signalling System No. one (DSS1) and Signalling System No.7 (SS7) parameters for Short Message Service (SMS) in fixed networks. The document is for implementations that carry SMS signalling between Integrated Services Digital Network (ISDN) local exchange functions and the Short Message Service Centre (SM-SC).

What does SIST ES 202 060-4 V1.1.1:2005 specify?

SIST ES 202 060-4 V1.1.1:2005 specifies the interworking needed for SMS between SS7 and DSS1, with its main purpose being the mapping between DSS1 and SS7 parameters. It focuses only on the functions relevant to this SMS interworking and does not repeat the standard UNI and NNI interworking procedures.

The document is organized into:

• Clause 1, scope
• Clause 2, references
• Clause 3, definitions and abbreviations
• Clause 4, description of the SMS interworking
• Annex A, bibliography

Clause 4 is the core of the document. It covers sending a Short Message, confirmation of reception, and the PABX variants of those flows.

What are the key requirements of SIST ES 202 060-4 V1.1.1:2005?

Sending a Short Message from the originating side

SIST ES 202 060-4 V1.1.1:2005 maps DSS1 SMS submission toward SS7 by using a FACILITY [DCR] or, for PABX cases, a REGISTER [CR] message on the DSS1 side and TC-BEGIN with SCCP and SMSFacility invoke on the SS7 side. In practice, this is the path that carries the user’s Short Message from the originating local exchange to the Short Message Service Centre.

The sMSC_Nr in the Submit invoke becomes the SCCP called party address. If sMSC_Nr is absent, the originating local exchange uses its stored default SMSC_Nr. The sending user shall provide the servedUserNr; if not, the network rejects the SMS.

Handling user identity and forwarding

SIST ES 202 060-4 V1.1.1:2005 uses sMSAdditionalOriginatingAddress to carry the servedUserNr unless presentation is restricted. If the user requests Short Message Sending User Identification Restriction (SMSUIR), the servedUserNr is omitted on the destination side.

The Short Message Service Centre (SM-SC) passes the received origin, destination, and protocol data unchanged unless a supplementary service requires different handling. It generates the outgoing sMSOriginatingAddress with its own ITU-T Recommendation E.164 number, and it may generate a restricted destination address when needed.

Supplementary service interactions

SIST ES 202 060-4 V1.1.1:2005 defines how SMS interworking behaves with SMSUIR, SM Forwarding, Anonymous SM Rejection (ASMR), Malicious SM Identification (MSMID), and white list/black list controls.

In practice:

• SMSUIR suppresses the servedUserNr toward the receiver.
• SM Forwarding may alter the destination address.
• ASMR rejects anonymous SMS when the receiving user has subscribed to that option, unless the sender is allowed to override it.
• MSMID replaces a hidden sender identity with a special SMS-ID so a malicious message can still be traced.
• White list and black list checks can allow or block SMS destinations or origins before delivery.

Destination-side mapping and reception confirmation

SIST ES 202 060-4 V1.1.1:2005 maps SS7 delivery toward DSS1 at the destination local exchange by converting SMSFacility into SMSDeliver and carrying the relevant addresses and protocol data. The sMSDestinationAddress is analysed by the SM-SC but not used for addressing the receiving user on the DSS1 side.

For reception confirmation, the standard defines the return path from DSS1 to SS7 and the corresponding SM-SC action. This matters when the network must report successful delivery back toward the originating side.

PABX operation

SIST ES 202 060-4 V1.1.1:2005 repeats the same interworking logic for PABX cases, but DSS1 uses REGISTER [CR] instead of FACILITY [DCR]. That lets PABX-based installations follow the same SMS interworking rules as other fixed-network cases.

What terms does SIST ES 202 060-4 V1.1.1:2005 define?

• Integrated Services Digital Network (ISDN) - The digital network type used as the service context for these SMS procedures.
• Short Message (SM) - The information carried by the SMS procedures in this standard.
• Short Message Service Centre (SM-SC) - The function that relays and store-and-forwards short messages between terminals.
• Short Message Terminal (SM-TE) - A terminal that can send or receive short messages.
• Short Message Sending User Identification Restriction (SMSUIR) - The option that restricts presentation of the sender’s identity to the receiver.
• Anonymous SM Rejection (ASMR) - The option that rejects anonymous SMS for a receiving user who has subscribed to it.
• Malicious SM Identification (MSMID) - The option that replaces hidden sender identification with a special SMS-ID for tracing.

Who uses SIST ES 202 060-4 V1.1.1:2005?

Telecom network operators use this standard when they implement SMS interworking in fixed networks. Service providers use it to control identity presentation, rejection, forwarding, and white list or black list behaviour.

Equipment vendors and system integrators use it for ISDN local exchanges, SM-SC functions, and PABX-based SMS support. It is especially relevant where DSS1 and SS7 signalling must exchange SMS-related parameters consistently.

Which standards are used with SIST ES 202 060-4 V1.1.1:2005?

• ITU-T Recommendation E.164 - Provides the numbering plan used for ISDN numbers and the SM-SC number.
• ETSI ES 202 060-3 - Gives the ISDN access protocol and related SMS handling, including rejection and delivery behaviour.
• ETSI ES 202 060-5 - Gives the network access protocol used alongside this part.
• ETSI EN 300 196-1 - Provides the DSS1 generic functional protocol for supplementary services, including invoke, return result, and return error components.
• ITU-T Recommendation I.112 - Supplies ISDN vocabulary used for the defined terms.
• ITU-T Recommendation I.130 - Supplies the three-level service characterization structure referenced in the foreword.

What does the SIST ES 202 060-4 V1.1.1:2005 document contain?

The document contains message-mapping tables for the originating, forwarding, destination, and confirmation paths. These tables show how DSS1 elements such as FACILITY, REGISTER, and SMS-related information elements map to SS7 components such as SCCP, TC-BEGIN, TC-END, SMSFacility, SMSSubmit, and SMSDeliver.

Clause 4 also explains the treatment of optional addresses and the effect of SMSUIR, SM Forwarding, ASMR, MSMID, and white list/black list controls. Annex A provides a bibliography with related ETSI and GSM documents.

Foreword
This ETSI Standard (ES) has been produced by ETSI Technical Committee Services and Protocols for Advanced
Networks (SPAN).
The present document is part 4 of a multi-part standard covering the Short Message Services (SMS) for fixed networks;
Networks Based Solution (NBS), as described below:
Part 1: "Overview";
Part 2: "Architecture and functional entities";
Part 3: "Integrated Services Digital Network (ISDN) access protocol";
Part 4: "Interworking between Signalling System No.7 (SS7) and Digital Subscriber Signalling System
No. one (DSS1)";
Part 5: "Network access protocol".
NOTE: The choice of a multi-part format for this deliverable is to facilitate maintenance and future
enhancements.
In accordance with ITU-T Recommendation I.130 [6], the following three level structure is used to describe the
supplementary telecommunication services as provided by European public telecommunications operators under the
pan-European ISDN:
- Stage 1 is an overall service description, from the user's standpoint;
- Stage 2 identifies the functional capabilities and information flows needed to support the service described in
stage 1; and
- Stage 3 defines the signalling system protocols and switching functions needed to implement the service
described in stage 1.
Introduction
The present document specifies the interworking between Signalling System No.7 (SS7) and the Digital Subscriber
Signalling System No. one (DSS1) for the Short Message Service.
The interworking between the above signalling protocols occurs in an exchange with ISDN local exchange functionality
and is specified in the context of a bearer unrelated connectionless or connection-oriented transaction in a pure ISDN.
