The contents of the present document are subject to continuing work within TC-SES and may change following formal TC-SES approval. Should TC-SES modiSl
31、the contents of the present document it will then be republished by ETSI with an identiSling change of release date and an increase in version number as follows: Version 1 .m.n where: the third digit (n) is incremented when editorial only changes have been incorporated in the specification; the seco
32、nd digit (m) is incremented for all other types of changes, i.e. technical enhancements, corrections, updates, etc. I n t rod uct ion 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-wor
33、k with other IMT-2000 family members through the UMTS core network. S-UMTS will be used to deliver 3rd generation mobile satellite services (MSS) utilizing either low (LEO) or medium (MEO) earth orbiting, or geostationary (GEO) satellite(s). For the purpose of the present document it is assumed that
34、 S-UMTS systems will be based on terrestrial 3GPP specifications and will support direct access to 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 satellite channe
35、l 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 corresponding T
36、-UMTS specification. Since S-UMTS is derived from T-UMTS, the organization of the S-UMTS specifications closely follows the original 3rd Generation Partnership Project (3GPP) structure. The S-UMTS numbers have been chosen to correspond to the 3GPP terrestrial UMTS numbering system but are prefixed w
37、ith S-UMTS. An S-UMTS system is defined by the combination of a family of S-UMTS specifications and T-UMTS specifications. NOTE 2: If an S-UMTS specification exists it takes precedence over the corresponding T-UMTS specification (if any). This precedence rule applies to any references in the corresp
38、onding T-UMTS specifications. ETSI 8 ETSI TR 101 865 VI .2.1 (2002-09) 1 Scope The present document describes the general aspects and principles that apply to satellite systems intended to be an integral part of the Universal Mobile Telecommunications System (UMTS)/IMT-2000. The S-UMTS systems consi
39、dered in the present document are expected to provide a comprehensive range of satellite services, mainly derived from the terrestrial UMTS network, to a range of mobile terminals including pocket phones, PDA types, car mounted plug-in and nomadic terminals. Also the use of intermediate module repea
40、ters (IMR) to improve coverage is highlighted. Evaluating the implication on the IP level completes the document. The ETSI TC-SES S-UMTS Working Group provides a forum to develop voluntary S-UMTS/IMT-2000 specifications. 2 Re fe re nces For the purposes of this Technical Report (TR), the following r
