- Specification, Functional Model and Information Flows - Short
Message Service (SMSSD)
This Standard specifies the Short Message Service (SMS).
SMS enables a user to send and receive Short Messages (SMs) to
and from another user.
This service is based on GSM 03.40. The Service Centre functionality
described in this Standard is equal to the functionality of a
Service Centre in GSM 03.40. Thus, for interoperability with a
GSM network, it is only necessary to implement a QSIG interface

in the herein described network.
The Short Message Service is a special kind of basic service but

Supplementary service specifications are produced in three stages,
according to the method described in ETS 300 387. This Standard
contains the stage 1 and stage 2 specifications of SMS. The stage
1 specification (clause 6) specifies the service as seen by users
of PISNs. The stage 2 specification (clause 7) identifies the
functional entities involved in the service and the information
flows between them.
