Introduction The present document has been prepared by the TC-SES Broadband Satellite Multimedia (BSM) working group based on the recommendations fro
19、m the work of STF-126 1. ETSI ETSI TR 101 984 V1.2.1 (2007-12) 6 1 Scope The present document defines the BSM services and architectures. It contains a set of definitions and reference models in the following main areas: BSM roles and actors; BSM reference architectures and models; BSM bearer servic
20、es. The present document is intended to define the possible roles that Broadband Satellite Multimedia systems may have, to define the main actors, to define a set of reference architectures and to define the services they can provide. These definitions are intended as a common set of definitions for
21、 BSM standardization. The overall objectives of BSM standardization are: to enable users to access a wide range of telecommunications services, including many that are today undefined, with particular emphasis on IP-based multi-media services and high data rates; to provide an efficient means of usi
22、ng satellite network resources (particularly radio spectrum); to facilitate the provision of a high quality of service similar to that provided by fixed networks; to facilitate the provision of easy to use, low cost terminals. 2 References References are either specific (identified by date of public

Non-specific reference may be made only to a complete document or a part thereof and only in the following cases: - if it is accepted that it will be possible to use all futur

Referenced documents which are not found to be publicly available in the expected location might be found at http:/docbox.etsi.org/Reference. For online referenced documents, information su
25、fficient to identify and locate the source shall be provided. Preferably, the primary source of the referenced document should be cited, in order to ensure traceability. Furthermore, the reference should, as far as possible, remain valid for the expected life of the document. The reference shall inc
26、lude the method of access to the referenced document and the full network address, with the same punctuation and use of upper case and lower case letters.

32、urposes of the present document, the following terms and definitions apply: broadcast: communication capability which denotes unidirectional distribution to an unspecified number of access points connected to the network NOTE: The communication may reach any or all access points and each terminal ma
33、y select which broadcast information to receive. BSM bearer service: user plane (U-plane) data transmission services provided by the BSM subnetwork at the SI-SAP interfaces. NOTE 1: A BSM bearer service includes all QoS and other bearer service properties, as viewed at those SI-SAP interfaces. NOTE
34、2: BSM bearer services are a specific form of layer 2 service access point services. BSM bearer services are therefore not the same as a Telecommunications bearer service as defined below. BSM Network: a BSM subnetwork together with the BSM interworking and adaptation functions that are required to
35、provide an interface into the attached networks BSM Subnetwork: all the BSM network elements below the Satellite Independent Service Access Point (SI-SAP) BSM System (BSMS): A BSM System corresponds to a BSM Network together with the NMC and NCC plus any additional elements that are required to prov
36、ide the network services to the subscribers and their users. channel: means of unidirectional transmission of signals between two points NOTE: Channel is a generic term that can be used at different layers of the interface (e.g. physical channel, logical channel). Several channels may share a common
37、 transport mechanism. connection oriented: communication method in which communication proceeds through three well-defined phases: connection establishment, data transfer, connection release connectionless: communication method which allows the transfer of information between users without the need
38、for connection establishment procedures ETSI ETSI TR 101 984 V1.2.1 (2007-12) 8 control plane (C-plane): plane which has a layered structure and performs control functions for the various services NOTE: The C-plane deals with the signalling necessary to set up, maintain and release bearer services.
39、gateway (GW): network element that provides interworking between the BSM network and one or more external networks. layer management functions: management functions (e.g. meta-signalling) relating to resources and parameters residing in its protocol entities link: capability to exchange data between
40、 two points NOTE 1: Link is a generic term that can be used at different layers of the interface. For example: data link: capability of the data link layer to exchange data; and physical link: capability of the physical layer to exchange data. NOTE 2: Physical link (radio link) names can be used to
41、indicate the direction and/or the usage and/or the operating band. For example, “uplink“, “feeder link“ or “Ku-band link“. management plane (M-plane): plane which provides two types of functions, namely layer management functions and network management functions multicast: communication capability w
42、hich denotes unidirectional distribution from a single ingress service access point to a number of specified egress service access points multipoint: communication configuration attribute which denotes that the communication involves more than two service access points Network Control Centre (NCC):
43、equipment that provides the central control functions for a satellite network. Network Management Centre (NMC): equipment that provides the central management functions for a satellite network. Satellite Independent Service Access Point (SI-SAP): the interface between the satellite dependent lower l
44、ayers and the satellite independent upper layers of the Satellite Terminal air interface Satellite Terminal (ST): network element that contains at least one satellite network interface. NOTE: An ST normally contains at least one other network interface and two different types of ST can be defined: U
45、ser ST: that provides interworking between the satellite network and a premises network. Gateway ST: that provides interworking between the satellite network and an external network. service attribute: specified characteristic of a telecommunication service NOTE: The value(s) assigned to one or more
46、 service attributes may be used to distinguish that telecommunication service from others. telecommunication service: service offered by a network operator or service provider to its customers in order to satisfy a specific telecommunication requirement NOTE: Telecommunication services are divided i
47、nto two broad families: bearer services and teleservices: telecommunications bearer service: type of telecommunication service that provides the capability of transmission of signals between user access points, typically the user-network interface (UNI); teleservice: type of telecommunication servic
48、e that provides the complete capability, including terminal equipment functions, for communication between users according to standardized protocols and transmission capabilities established by agreement between operators traffic class (or service class): service offered to the users described by a
49、set of performance parameters and their specified values, limits or ranges NOTE: The set of parameters provides a comprehensive description of the service capability. user plane (U-plane): plane which has a layered structure and provides for user data transfer ETSI ETSI TR 101 984 V1.2.1 (2007-12) 9 3.2 Abbreviations For the purposes of the present document, the following abbreviations apply: ASP Application Service Provider AESA ATM End System Addresses ATM Asynchronous Transfer Mode BSM Broadband Satellite Multimedia BSMS Broadband Satel
