GSC#8 April 2003, DRAFT GSC-8, OTTAWA Slide 15 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

GSC#8 April 2003, DRAFT GSC-8, OTTAWA Slide 16 Working Group Broadband Satellite Multimedia ( 2) 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.

GSC#8 April 2003, DRAFT GSC-8, OTTAWA Slide 17 Working Group Broadband Satellite Multimedia ( 3) Working Group Broadband Satellite Multimedia ( 3)  BSM WG has set the following priorities: –GSO satellites –Fixed systems –Internet Protocol IPv4, IPv6  Current work items:  IP interworking standards Satellite Independent set of higher layer standards  Air interfaces Satellite dependent families of lower layer specifications  Satellite Independent interface (SI-SAP) Common interface between higher layers and lower layers

GSC#8 April 2003, DRAFT GSC-8, OTTAWA Slide 19 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.
