Foreword
This ETSI Standard (ES) has been produced by ETSI Technical Committee Services and Protocols for Advanced
Networks (SPAN).
The present document is part 3 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 [4], 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 SM service. The stage 1 aspects are detailed in ES 201 986 [10]. The stage 2 aspects of the SM service have
not been specified.
The present version updates the references to the basic call specifications.
Introduction
The Short Message Service (SMS) is a service, applicable at the coincident S and T reference point and T reference
point, to provide the served user the ability to send and receive Short Messages. The Short Messages (SM) are
exchanged between the sending and receiving user via a Short Message Service Centre (SM-SC).
ETSI
5 ETSI ES 202 060-3 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 European public telecommunications operators at the T reference
point or coincident S and T reference point (as defined in ITU-T Recommendation I.411 [6]) by means of the Digital
Subscriber Signalling System No. one (DSS1) protocol. Stage three identifies the protocol procedures and switching
functions needed to support a telecommunication service (see ITU-T Recommendation I.130 [4]).
In addition, the present document specifies the protocol requirements at the T reference point where the service is
provided to the user via an intermediate private ISDN.
The present document does not specify the additional protocol requirements where the service is provided to the user
via a telecommunication network that is not an ISDN but it does include interworking requirements of other networks
with the public ISDN.
The SM service is provided independently of a call.
Charging principles are outside the scope of the present document.
The SM service 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 (served user) or separated
from the network of the SM originating user.
NOTE: The SM service is typically used between a Short Message service provider and a user (receiving user) of
the Short Message service provided.
Further parts of the present document specify the method of testing required to identify conformance to the present
document.
The present document is applicable to equipment supporting the SM service, to be attached at either side of a
T reference point or coincident S and T reference point when used as an access to the public ISDN.

4 Description
The Short Message Service (SM) service shall be available to users who are connected to the network via a basic access
or primary rate access.
The Short Message Service (SMS) enables an originating user to send a SM of a limited size to a destination user.
A Short Message (SM) can be initiated upon a request of the sending user or by the service provider itself, and shall be
sent to the receiving user. An SM is always conveyed via an SM-SC. The SM-SC receives the SM from an originating
SM-TE (sending user), converts the message if necessary, and relays the SM to the terminating SM-TE (receiving user).

Figure 1: SMS submission, delivery and confirmation
A submit report is sent from an SM-SC to an SM-TE within a sMSSubmit return result component and may be either a
positive report, which confirms the correct submission of an SM to the SM-SC, or a negative report, which informs the
SM-TE that the SM was not successfully submitted with the error reason.
A deliver report is sent to an SM-SC within a sMSDeliver return result and may be either a positive report, which
confirms the correct delivery of an SM to the receiving SM-TE, or a negative report, which informs the SM-SC that the
SM was not successfully delivered with the error reason.
If the option to provide a status report is invoked and supported, a status report is sent from the SM-SC to the
originating SM-TE in a sMSDeliver invoke component; the SM-TE acknowledges correct receipt of the status report.
Having received one or more SMs, the receiving user can subsequently read, store or delete the messages on its
terminal. If the SM-TE supports the optional Replace Short Message Function, Short Messages (SMs) with the
respective Replace Short Message Type indication held in the SM-TE are automatically replaced by received new ones.
The means by which the receiving user manages these features are outside the scope of the present document.
The preparation of an SM as well as the kind of data transmission between the sending or receiving users and the
SM-SC are outside the scope of the present document.

Table 2 shows the definitions of the operations and errors required for the SM service using ASN.1 as specified in
ITU-T Recommendation X.680 [8] and using the OPERATION and ERROR macros as defined in figure 4 of
ITU-T Recommendation X.880 [9].
The formal definition of the component types to encode these operations and errors is provided in clause D.1 of
EN 300 196-1 [1].
The inclusion of components in facility information elements is defined in EN 300 196-1 [1], clause 11.2.2.1.
All components (invoke, return result, return error and reject) shall be included within a facility information element.
This facility information element may be included in any appropriate message as specified in EN 300 196-1 [1],
