• The GMR specifications are organized into two releases:
– Release 1 specifications.
• Defines the GMR circuit mode services, which are based
on the GSM phase 2 circuit mode services.
• Release 1 of the GMR air interface specifications have
been published jointly in ETSI (TC-SES) and in the TIA
(TR 34.1)
– Release 2 specifications.
• Defines the GMR packet mode services (GMPRS) which
are based on the GSM phase 2+ packet mode services
(GPRS).
• Release 2 specifications are an evolution of the GMR
Release 1 specifications.

Slide 14
Working Group Broadband Satellite
Multimedia
 To produce specifications, standards and other ETSI
deliverables for broadband satellite multimedia. This
includes:
– Definition of satellite system architectures
supporting broadband services
– Service requirements and descriptions for
broadband communications systems
– Definition of network architectures and interface
protocols leading to air interface standards,
interworking standards and other user terminal
specifications.
 To liaise with relevant other standardization bodies
(e.g. TIA, ITU) on satellite matters

Slide 15
Working Group Broadband Satellite
Multimedia ( 2)
 The BSM concept is to divide the
air interface into 2 parts:
 Satellite independent upper
layers
 Satellite dependent lower
layers
 The upper layers should contain a
set of common IP interworking
functions:
– Common ways of handling IP
addressing, multicast and QoS
etc.
 The lower layers contain the
satellite specific parts.
– These layers are closely tied to
the payload capability of the
satellite and hence cannot be
the same in all cases.

Working Group European Co-operation for Space
Standardisation(1)
• Satellite Ground Interface Command and Control
Link of Geostationnary Satellites
 Domain Telemetry, Command and Ranging (TCR) systems
operating typically in the following bands: 5850 MHz;6725 MHz
uplink, 3400 MHz;4200 MHz downlink, 12750 MHz;14800 MHz
and17300 MHZ;18100 MHz uplink, 10700 MHZ;12750 MHz
downlink
 Sets : out the minimum performance requirements and
technical characteristics of the ground/satellite Radio
Frequency (RF) interface partially based on Spread Spectrum
Multiple Access (SSMA).
 Motivation : Management of the co-location constraints for
maximization of bandwidth for Communications Missions, and
interference minimisation

Slide 18
Working Group European Co-operation for
Space Standardisation(2)
• Satellite Software Data Handling Interfaces (SSDHI)
 Domain : Geostationary Communications Satellite architectures
based on ISO OSI Reference Model or SOIF Reference Model,
but could also be applied to other types of satellites.
 Sets : the minimum definition, services and interfaces
requirements of the satellite communication application layer
 Motivation : Shorter and shorter communications satellites
development cycles and compatibility requested with off the
shelf equipments requires interface standardisation.
Independent development of On Board Software (OBSW) of the
choice of satellite equipment by standardisation the software
specifications of the Interface between the application software
and the communication services.

Conclusions
 SINCE RAST 10 ETSI TC SES:
 Continue the Harmonisation standard work (RTTE D)
 Continue the development of an open standard for new
broadband products
 Continue to be the focal point in Europe for Satellite
Standards
 And for the Future?
 Continuing the work on Open Standard under the eEurope
Broadband development
 Intend to be part in the standardisation of Galileo
 Continuing the co-operation with TIA and TTA
