Foreword This Technical Specification (TS) has been produced by ETSI Technical Committee Satellite Earth Stations and Systems (SES). The present document is part 1 of a multi-part deliverable covering Satellite Earth Stations and

15、 Systems (SES); Satellite Component of UMTS/IMT-2000; Multimedia Broadcast/Multicast Services, as identified below: Part 1: “Services definitions“; Part 2: “Architecture and functional description“; Part 3: “Introduction in the Radio Access Network (RAN)“; Part 4: “Interworking with terrestrial UMTS

16、 networks“; Part 5: “Performances over the radio interface“; Part 6: “Security“. 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 thr

17、ough the UMTS core network. S-UMTS will be used to deliver 3rdgeneration 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 cor

18、e 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 specif

19、ications 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. Since S-UMTS is derived from T-UMTS, the organization of the S-UMTS specifications clo

20、sely follows the original 3rdGeneration Partnership Project (3GPP) structure. 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 a

21、ny). This precedence rule applies to any references in the corresponding 3GPP specifications. ETSI ETSI TS 102 442-1 V1.1.1 (2006-11) 5 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 con

22、tain 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. ETSI ETSI TS 102 442-1 V1.1.1

23、 (2006-11) 6 1 Scope The present document specifies the set of requirements for the support of Satellite Multimedia Broadcast Multicast Services. The present document includes information applicable to network operators, content providers, terminal and network manufacturers. Broadcast and Multicast

24、are methods for transmitting data-grams from a single source to several destinations (point-to-multipoint). It is envisaged that for some applications, multiple users can receive the same data at the same time. The benefit of multicast and broadcast in the network is that the data is sent once on ea

25、ch link. For example, a network operator will send data to a satellite hub in order satellite broadcasts data regardless of the number of UEs that wish to receive it. The benefit of multicast and broadcast on the air interface is that many users can receive the same data on a common channel, thus no

26、t clogging up the satellite air interface with multiple transmissions of the same data. With increasing use of high bandwidth applications in third generation mobile systems, especially with a large number of users receiving the same high data rate services, terrestrial cellular networks and transpo

27、rt infrastructure are on the way of being overloaded. Satellite broadcast and multicast is an efficient alternative to relieve terrestrial networks and to extend service coverage in low dense and sparse population areas. 2 Void 3 Definitions and abbreviations 3.1 Definitions For the purposes of the

28、present document, the following terms and definitions apply: broadcast mode: part of S-MBMS that supports broadcast services. broadcast service: unidirectional point-to-multipoint service in which data is efficiently transmitted from a single source to multiple UEs in the associated broadcast servic

29、e area NOTE: Broadcast services may be received by all users who have enabled the specific broadcast service locally on their UE and who are in the broadcast area defined for the service. broadcast service area: area in which a specific broadcast service is available. It is defined individually per

30、broadcast service NOTE: The broadcast service area may represent the coverage area of the entire PLMN (satellite coverage areas), or part(s) of the PLMNs coverage area (spot coverage area). The broadcast service area is the sum of all local broadcast areas offering the same service. broadcast sessio

31、n: continuous and time-bounded reception of a broadcast service by the UE. NOTE: A single broadcast service can only have one broadcast session at any time. A broadcast service may consist of multiple successive broadcast sessions. local broadcast area: area of a broadcast service, where the service

32、 content is the same NOTE: One broadcast service may have different content in different local broadcast areas. ETSI ETSI TS 102 442-1 V1.1.1 (2006-11) 7 local multicast area: area of a multicast service, where the service content is the same NOTE: One multicast service may have different content in

33、 different local multicast areas. Mobile Station (MS): Defined in TS 124 002 (see Bibliography). NOTE: The abbreviation “UE“ in this specification refers both to MS and User Equipment. Multimedia Broadcast/Multicast Service (S-MBMS): unidirectional point-to-multipoint service in which data is transm

34、itted from a single source entity to a group of users in a specific area. The MBMS has two modes: Broadcast mode and Multicast mode. multicast joining: process by which a user joins a multicast group multicast mode: part of S-MBMS that supports multicast services multicast service: unidirectional po

35、int-to-multipoint service in which data is efficiently transmitted from a single source to a multicast group in the associated multicast service area. Multicast services can only be received by such users that are subscribed to the specific multicast service and have joined the multicast group assoc

36、iated with the specific service. multicast service area: area in which a specific multicast service is available. It is defined individually per multicast service. The multicast service area may represent the coverage area of an entire PLMN, or part(s) of the PLMNs coverage area. The multicast servi

37、ce area is the sum of all local multicast areas offering the same service. multicast session: continuous and time-bounded reception of a multicast service by the UE. A single multicast service can only have one multicast session at any time. A multicast service may consist of multiple successive mul

38、ticast sessions. multicast subscription: process by which a user subscribes or is subscribed to a multicast subscription group and thereby is authorized to join certain multicast services NOTE: Multicast subscription is performed either upon user selection or due to home environment initiation. mult

39、icast subscription group: group of users who are subscribed to a certain MBMS in multicast mode and therefore authorized to join and receive multicast services associated with this group multicast transmission activation: process by which the network activates the transmission of Multicast data Sate

43、t/multicast service (S-MBMS) Point to multipoint services allow data from a single source entity to be transmitted to multiple endpoints. These services are expected to be used extensively and satellite broadcast capability to a large population makes satellite a good candidate to complement terrest

44、rial networks. S-MBMS is a unidirectional point to multipoint bearer service in which data is transmitted from a single source entity (satellite) to multiple recipients. It is anticipated that other services will use these bearer capabilities. Two modes of operation are defined: the broadcast mode.

45、The multicast mode. 4.1 Broadcast mode The broadcast mode is a unidirectional point-to-multipoint transmission of multimedia data (e.g. text, audio, picture, video) from a single source entity to all users in a broadcast service area. The broadcast mode is intended to efficiently use radio/network r

46、esources. Data is transmitted over a common radio channel. Data is transmitted in the broadcast service area as defined by the network (home environment). S-MBMS data transmission should adapt to different radio resource availability, e.g. by reducing the bit rate of the S-MBMS data. A broadcast ser

47、vice received by the UE, involves one or more successive broadcast sessions. A broadcast service might, for example, consist of a single on-going session (e.g. a media stream) or may involve several intermittent sessions over an extended period of time (e.g. messages). An example of a service using

48、the broadcast mode could be advertising or be a welcome message to the network or mobile TV. As not all users attached to the network may wish to receive these messages then the user shall be able to enable/disable the reception of these broadcast service on his UE. The broadcast mode differs from t

49、he multicast mode in that there is no specific requirement to activate or subscribe to the S-MBMS in broadcast mode. The broadcast mode should allow terminals to minimize their power consumption. It is expected that charging data for the end user will not be generated for this mode at transport service layer. Charging data related to security procedures for the end user at User Service layer may be generated. The reception of the traffic in the broadcast mode is not guaranteed. The receiver may be able to recognize data loss. Figure 1 gives an example of how
