SIST ES 202 060-5 V1.1.1:2005 is a SIST publication of the ETSI standard for Short Message Service (SMS) in fixed networks. It specifies the stage 3 network access protocol for the Network Based Solution (NBS), using Signalling System No. 7 (SS7) Transaction Capabilities (TC) to define how a Short Message Service Centre (SM-SC) communicates with local exchanges.

It is the document to use when you need the signalling, coding and routing rules for SMS submission and delivery in a fixed-network environment. The standard is aimed at network operators, service providers and implementers of local exchanges, SM-SC functions and SS7-based interworking.

What does SIST ES 202 060-5 V1.1.1:2005 specify?

SIST ES 202 060-5 V1.1.1:2005 specifies the stage 3 protocol for SMS in the pan-European Integrated Services Digital Network (ISDN) using SS7 TC procedures. The SMS is provided independently of a call, and the protocol covers communication between an originating local exchange (OLE), a Short Message Service Centre (SM-SC), and a destination local exchange (DLE).

The document is organized into clauses 1 to 10, covering scope, references, definitions, service description, operational requirements, coding requirements, signalling procedures, interworking with non-TC networks, interaction with other supplementary services, and timer values. It also includes one normative annex and two informative annexes.

Annex	What it covers
Annex A	Signalling flow diagrams for successful and unsuccessful submission and delivery cases
Annex B	Assignment of object identifier values
Annex C	Bibliography

The scope excludes charging principles, testing and maintenance requirements. It also notes that the SM-SC may be connected directly by SS7 or behind a network element service centre (NE-SC) using DSS1 or other protocols.

What are the key requirements of SIST ES 202 060-5 V1.1.1:2005?

Network capabilities and roles

SIST ES 202 060-5 V1.1.1:2005 requires the OLE and the DLE to support SCCP and TC with an SMS-ASE, while intermediate exchanges involved in SMS transmission need SCCP capability. In practice, this means the network path must support SS7 signalling and transaction handling where SMS messages are submitted or delivered.

The service is split into two steps: submission from the sender to the SM-SC, and delivery from the SM-SC to the receiver. That separation matters because the sending side and receiving side follow different TC procedures and different error handling rules.

SMSFacility coding and data

Clause 6 defines the SMS-ASE operation SMSFacility and the associated component types. Tables 1 to 3 show how SMSFacility is used as an Invoke, Result or Error component between OLE, SM-SC and DLE.

The coded information includes addressing and identification parameters for originating and destination numbers, plus service parameters such as the type of protocol transported and the protocol data. For international SMS, the country code must be included in the originating user number. In practice, implementers have to map the network numbers and the carried user data into the ASN.1 structure exactly as specified.

Clause 6 also lists the error types used by the service, including resource unavailable, invalid originating number, invalid destination number, destination line busy and user not responding. This matters because network and terminal software must convert signalling failures into one of the defined service errors.

Signalling procedures and dialogue handling

Clause 7 defines the operational signalling sequence. Only class 1 operations are used, each TC message carries a single SMS operation, and the dialogue is structured using TC primitives.

For submission from OLE to SM-SC, the OLE sends an SMSFacility Invoke component that includes the relevant addresses and the user data. The SM-SC replies with a Result component when the operation succeeds. For delivery from SM-SC to DLE or OLE, the SM-SC uses the same operation structure, with the exchange replying by Result when delivery succeeds.

The standard also defines exceptional procedures. If TC aborts, rejects or routing fails, the submission is treated as unsuccessful. A supervision timer, SMS-Tsup, protects the operation; it is used both at the sender and at the receiver side, and its duration is 10 seconds. In practice, that timer sets the upper limit for how long an exchange waits for the other side to answer.

Routing, interworking and supplementary service interaction

Clause 7.3 defines SCCP routing rules based on Global Title translation. The text fixes the use of the ISDN/Telephony numbering plan E.164, the SSN indicator, the GT indicator and the routing indicator for SMS signalling. This is the part that ensures the SS7 network routes SMS messages to the correct SM-SC or user exchange.

Clause 8 says interworking with a network part without SMS-ASE capability is not possible, and the same applies where SCCP/TC capability is absent at OLE or DLE. A possible alternative is UBS(1/2) inband. For operators, that is a clear architectural constraint: this protocol needs TC and SCCP support in the SMS path.

Clause 9 records the interaction with other supplementary services. Explicit call transfer has no impact on the SMS destination address, closed user group restrictions apply as they do for speech/data, and subaddress information is not supported in SMS-ASE operations. Some diversion services are referred back to the SMS service description in ES 201 986.

What terms does SIST ES 202 060-5 V1.1.1:2005 define?

• Short Message Service Centre (SM-SC) - the function that relays and store-and-forwards a short message between two SM-TEs.
• Short Message Terminal (SM-TE) - the terminal that sends or receives short messages.
• Originating Local Exchange (OLE) - the local exchange where the originating SMS user is connected.
• Destination Local Exchange (DLE) - the local exchange where the receiving SMS user is connected.
• Network Based Solution (NBS) - the SMS implementation placed in the public network rather than in the end-user equipment.
• SMSFacility - the TCAP operation used to carry SMS submission, delivery, result and error information.
• Protocol Data - the NBS parameter that encapsulates the access protocol, including UBS1 or UBS2 transfer-layer data.

Who uses SIST ES 202 060-5 V1.1.1:2005?

This standard is used by public telecommunications operators, SMS service providers, and vendors or integrators of fixed-network switches and service centres. It is relevant to engineers designing SS7/TC-based SMS routing, to quality managers checking protocol conformance, and to buyers assessing whether a network element can support the NBS SMS architecture. It is especially relevant in PSTN/ISDN fixed networks where the SM-SC may sit inside the network or behind an NE-SC.

Foreword
This ETSI Standard (ES) has been produced by ETSI Technical Committee Services and Protocols for Advanced
Networks (SPAN).
The present document is part 5 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.
The present document details the stage 3 aspects (signalling system protocols and switching functions) needed to
support the SMS. The stage 1 aspects are detailed in ETS 201 986 [10]. The stage 2 aspects of the SMS have not been
specified.
The present version updates the references to the basic call specification.
Introduction
The Short Message Service (SMS) is a service providing the served user the ability to send and receive Short Messages
(SM). The Short Messages (SM) are exchanged between the sending and receiving user via a Short Message Service
Centre (SM-SC).
ETSI
6 ETSI ES 202 060-5 V1.1.1 (2003-05)
1 Scope
The present document specifies the stage three of the Short Message Service (SMS) for the pan-European Integrated
Services Digital Network (ISDN) as provided by the European public telecommunications operators by means of the
Signalling System No.7 Transaction Capabilities (TC) application protocol. The stage three identifies the protocol
procedures and switching functions needed to support a telecommunication service (see ITU-T
Recommendation I.130 [6]).
The SMS is provided independently of a call.
Charging principles are outside the scope of the present document.
Testing and maintenance requirements are outside the scope of the present document.
The SMS enables the originating SMS user to send Short Messages (SMs) to the receiving SMS user via a Short
Message Service Centre (SM-SC), belonging to the network of the SMS originating user or separated from the network
of the SMS originating user.
NOTE: The SMS is typically used between a Short Message service provider and a user of the Short Message
service provided.
The SM-SC can be connected to the network by SS#7 or behind a NE-SC with DSS1 or other protocols.
