Foreword This Technical Report (TR) has been produced by ETSI Technical Committee Satellite Earth Stations and Systems (SES). I n

11、t rod uct ion Broadband Satellite Multimedia (BSM) existing and planned systems 11 and 2 will provide consumers in corporate, public and home environments broadband access to the Internet and to multimedia applications. Broadband Satellite Multimedia access systems are intended as high performance,

12、quick to set up, competitive alternatives for wire-based access systems particularly in the geographical areas where it will not be economically viable to deploy, for instance, xDSL networks. Broadband Satellite Multimedia systems inter-work with several core networks typically based on MPLS, ATM, o

13、r IP. They operate in the frequency spectrum allocated to Fixed Satellite Services (FSS). ETSI 5 ETSI TR 102 187 VI .I .I (2003-05) 1 Scope The present document has been produced by ETSI Technical Committee Satellite Earth stations and Systems (TC SES). It provides the definitions of the Family Name

14、s of Broadband Satellite Multimedia (BSM). 2 Re fe re nces For the purposes of this Technical Report (TR) the following references apply: il ETSI TR 101 374-1: “Satellite Earth Stations and Systems (SES); Broadband satellite multimedia; Part 1 : Survey on standardization objectives“. ETSI TR 101 374

16、For the purposes of the present document, the following terms and definitions apply: Satellite Access Function (SAP): logical function that provides interworking between the BSM bearer service and an End System, either directly or via a local network (e.g. a LAN) Satellite Gateway Function (SGF): lo

17、gical function that provides interworking between the BSM bearer services and a core network, either directly or via a transit network 3.2 Abbreviations For the purposes of the present document, the following abbreviations apply: BSM Broadband Satellite Multimedia FSS Fixed Satellite Services SAF Sa

18、tellite Access Function SGF Satellite Gateway Function 4 Families of BSM systems 4.1 Family names To ensure that a Technical Specification can be re-used by various systems, it is required to class them under families to maximize the commonalties between them. This will also facilitate, when appropr

19、iate, not only interoperability between these systems or between components of these systems within a same family but also between systems that are members of different families. Different families are expected to refer to different satellite networks including both Star and Mesh network topologies

20、and including regenerative and transparent satellites. Some may only provide forward and return channels over satellite (Satellite) when others may use an optional terrestrial return path (Hybrid). These main alternatives are summarized in the following table which also defines the 3-letter prefix (

21、1-2-3) that will be used to designate these families. ETSI 6 ETSI TR 102 187 VI .I .I (2003-05) PREFIX MEANING 1 - SATELLITE TYPE -2- RETURN CHANNEL -3 TOPOLOGY Table 1: Family names - definition of the prefix DEFINITION OF THE PREFIX R = Regenerative (OBP); or T = Transparent (bent pipe) S = Satell

Therefore the following families are identified: Table

25、ctional requirements These interfaces are defined in the BSM Services and Architectures 3 as follows: 1.2 is the BSM Network Interface; the interface between satellite access function and the customer premises networks; I.5D.6 are the Air interfaces; 1.10 is the BSM Gateway Interface; the interface between the satellite gateway function and terrestrial networks.
