Foreword This Technical Specification (TS) has been produced by ETSI Technical Committee Satellite Earth Stations and Systems (SES). The present docu

25、ment is part 3 of a multi-part deliverable covering Satellite Earth Stations and 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

26、 in the Radio Access Network (RAN)“; Part 4: “Interworking with terrestrial UMTS networks“; Part 5: “Performances over the radio interface“; Part 6: “Security“. ETSI ETSI TS 102 442-3 V1.1.1 (2006-11) 6 Introduction S-UMTS stands for the Satellite component of the Universal Mobile Telecommunication

27、System. S-UMTS systems will complement the terrestrial UMTS (T-UMTS) and inter-work with other IMT-2000 family members through 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 geostationa

28、ry (GEO) satellite(s). S-UMTS systems are based on terrestrial 3GPP specifications and will support access to GSM/UMTS core 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 s

29、atellite channel characteristics, some modifications to the terrestrial UMTS (T-UMTS) standards are necessary. Some specifications are directly applicable, whereas others are applicable with modifications. Similarly, some T-UMTS specifications do not apply, whilst some S-UMTS specifications have no

30、corresponding T-UMTS specification. Since S-UMTS is derived from T-UMTS, the organization of the S-UMTS specifications closely 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 specifi

31、cations, as follows: If an S-UMTS specification exists it takes precedence over the corresponding 3GPP specification (if any). This precedence rule applies to any references in the corresponding 3GPP specifications. NOTE 2: Any references to 3GPP specifications within the S-UMTS specifications are n

32、ot subject to this precedence rule. For example, an S-UMTS specification may contain 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

33、 specifications shall be defined at a later stage. ETSI ETSI TS 102 442-3 V1.1.1 (2006-11) 7 1 Scope The present document specifies the support of Multimedia Broadcast/Multicast Service in S-UMTS, based on a point to multipoint connection, either directly from satellite or via terrestrial repeaters

43、 The requirements inherited from 3GPP for the support of S-MBMS are: 1) S-MBMS data transfer shall be downlink only. 2) QoS attributes shall be the same for S-MBMS Multicast and Broadcast modes. 3) During S-MBMS data transmission it shall be possible to receive paging messages from both satellite an

44、d terrestrial networks. 4) Simultaneous reception of S-MBMS and non-S-MBMS services shall depend upon UE capabilities. 5) Simultaneous reception of more than one S-MBMS services shall depend upon UE capabilities. 6) A notification procedure shall be used to indicate the start of S-MBMS data transmis

45、sion. This procedure shall contain S-MBMS Radio Bearer information. 7) S-MBMS UE multicast activation (Joining) and broadcast subscription shall be transparent to USRAN. 8) Reception of S-MBMS shall not be guaranteed at RAN level. S-MBMS does not support individual retransmissions at the radio link

46、layer, nor does it support retransmissions based on feedback from individual subscribers at the radio level. This does not preclude the periodic repetitions of the S-MBMS content based on operator or content provider scheduling or retransmissions based on feedback at the application level. 9) A mech

47、anism to provide USRAN the received QoS per UE is not required as part of S-MBMS. ETSI ETSI TS 102 442-3 V1.1.1 (2006-11) 9 10) UE controlled “service based“ spot/IMR cell selection/reselection shall not be permitted. 11) In the case of USRAN only, guaranteed “QoS“ linked to a certain initial downli

48、nk power setting is not required. 12) S-MBMS charging should be transparent to the RAN. 13) S-MBMS should allow for low UE power consumption. 14) Header compression should be used. 4.1.2 S-MBMS Notification Requirements The requirements inherited from 3GPP for notification are: 1) S-MBMS notificatio

49、n shall be transmitted within the S-MBMS service area. 2) S-MBMS notification shall be sent so it could be received by all UEs with an activated S-MBMS service, regardless of their RRC state or the lack of an RRC connection. 3) S-MBMS notification should maximize the reuse of existing channels. 4) S-MBMS notification should allow terminals to minimize their power consumption, meaning that UEs with an activated S-MBMS service should not listen permanently, but at regular intervals to S-MBMS notification. 5) Reception of S-MBMS notification cannot be guaranteed. 6
