All published ETSI deliverables shall include information which directs the reader to the above source of information.
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

SIST ES 202 060-5 V1.1.1:2005

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.

4 Description
The Short Message Service (SMS) provides a means for sending a message of a limited size to and from a terminal
equipment.
The SMS can be realised in two ways, either as a User Based Solution (UBS) or as a Network Based Solution (NBS).
NOTE 1: For recall, the User Based Solution is provided as part of a function within the end-user equipment, which
does not require any specific short message transfer function inside the public network. Only the basic
call procedures within the public network and the CLI supplementary service are used.
Two UBS protocols (UBS1 and UBS2) are available and described in the AT document (see ES 201 912 [11]).
Protocol 1: Transfer and application layers are fully compliant with the GSM SMS service, and with the DSS1 SM
payload.

NOTE 2: The Network Based Solution is provided as part of a function within the public network and does not
require a voice-band communication path between the SM-TE and SM-SC.

5 Operational requirements
5.1 Provision and withdrawal
See ES 201 986 [10] for provision or withdrawal conditions of the service.
5.2 Requirements on OLE
The OLE needs the capabilities of Signalling Connection Control Part (SCCP) (see ETS 300 009 [1]) and TC
(see ETS 300 287 [3]) with an SMS-ASE.
5.3 Requirements on intermediate exchanges
The intermediate exchanges involved in the transmission of the SMS operation need the capability of SCCP
(see ETS 300 009 [1]).
5.4 Requirements on DLE
The receiving user's exchange needs the capabilities of SCCP (see ETS 300 009 [1]) and TC (see ETS 300 287 [3]) with
an SMS-ASE.
