Foreword
This Technical Specification (TS) has been produced by ETSI Technical Committee Satellite Earth Stations and
Systems (SES).
The present document is specifying the Satellite Radio Interface referenced as SRI Family G at ITU-R, in the frame of
the modification of ITU-R Recommendation M.1457-5 [7]. This modification has been approved at ITU-R SG8
meeting in November 2005.
The present document is part 6, sub-part 1 of a multi-part deliverable covering Satellite Earth Stations and Systems
(SES); Satellite Component of UMTS/IMT-2000; G-family, as identified below:
Part 1: "Physical channels and mapping of transport channels into physical channels";
Part 2: "Multiplexing and channel coding";
Part 3: "Spreading and modulation";
Part 4: "Physical layer procedures";
Part 5: "UE Radio Transmission and Reception";
Part 6: "Ground stations and space segment radio transmission and reception";
Sub-part 1: "G-family (S-UMTS-G 25.104)".
Introduction
S-UMTS stands for the Satellite component of the Universal Mobile Telecommunication System. S-UMTS systems will
complement the terrestrial UMTS (T-UMTS) and inter-work with other IMT-2000 family members through the UMTS
rd
core network. S-UMTS will be used to deliver 3 generation Mobile Satellite Services (MSS) utilizing either low
(LEO) or medium (MEO) earth orbiting, or geostationary (GEO) satellite(s). S-UMTS systems are based on terrestrial
3GPP specifications and will support access to GSM/UMTS core networks.
NOTE 1: The term T-UMTS will be used in the present document to further differentiate the Terrestrial UMTS
component.
Due to the differences between terrestrial and satellite channel characteristics, some modifications to the terrestrial
UMTS (T-UMTS) standards are necessary. Some specifications are directly applicable, whereas others are applicable
with modifications. Similarly, some T-UMTS specifications do not apply, whilst some S-UMTS specifications have no
corresponding T-UMTS specification.

7 ETSI TS 101 851-6-1 V2.1.1 (2008-01)

Since S-UMTS is derived from T-UMTS, the organization of the S-UMTS specifications closely follows the original
rd
3 Generation Partnership Project (3GPP) structure. The S-UMTS numbers have been designed to correspond to the
3GPP terrestrial UMTS numbering system. All S-UMTS specifications are allocated a unique S-UMTS number as
follows:
S-UMTS-n xx.yyy
Where:
• The numbers xx and yyy correspond to the 3GPP-numbering scheme.
• n (n=A, B, C, etc.) denotes the family of S-UMTS specifications.
An S-UMTS system is defined by the combination of a family of S-UMTS specifications and 3GPP specifications, as
follows:
• If an S-UMTS specification exists it takes precedence over the corresponding 3GPP specification (if any). This
precedence rule applies to any references in the corresponding 3GPP specifications.
NOTE 2: Any references to 3GPP specifications within the S-UMTS specifications are not subject to this
precedence rule. For example, an S-UMTS specification may contain specific references to the
corresponding 3GPP specification.
• If an S-UMTS specification does not exist, the corresponding 3GPP specification may or may not apply. The
exact applicability of the complete list of 3GPP specifications shall be defined at a later stage.
