Introduction GMR stands for GEO (Geostationary Earth

25、 Orbit) Mobile Radio interface, which is used for mobile satellite services (MSS) utilizing geostationary satellite(s). GMR is derived from the terrestrial digital cellular standard GSM and supports access to GSM core networks. The present document is part of the GMR Release 2 specifications. Releas

26、e 2 specifications are identified in the title and can also be identified by the version number: Release 1 specifications have a GMR-1 prefix in the title and a version number starting with “1“ (V1.x.x.). Release 2 specifications have a GMPRS-1 prefix in the title and a version number starting with

27、“2“ (V2.x.x.). The GMR release 1 specifications introduce the GEO-Mobile Radio interface specifications for circuit mode mobile satellite services (MSS) utilizing geostationary satellite(s). GMR release 1 is derived from the terrestrial digital cellular standard GSM (phase 2) and it supports access

28、to GSM core networks. The GMR release 2 specifications add packet mode services to GMR release 1. The GMR release 2 specifications introduce the GEO-Mobile Packet Radio Service (GMPRS). GMPRS is derived from the terrestrial digital cellular standard GPRS (included in GSM Phase 2+) and it supports ac

29、cess to GSM/GPRS core networks. Due to the differences between terrestrial and satellite channels, some modifications to the GSM standard are necessary. Some GSM specifications are directly applicable, whereas others are applicable with modifications. Similarly, some GSM specifications do not apply,

30、 while some GMR specifications have no corresponding GSM specification. Since GMR is derived from GSM, the organization of the GMR specifications closely follows that of GSM. The GMR numbers have been designed to correspond to the GSM numbering system. All GMR specifications are allocated a unique G

31、MR number. This GMR number has a different prefix for Release 2 specifications as follows: Release 1: GMR-n xx.zyy. Release 2: GMPRS-n xx.zyy. where: - xx.0yy (z = 0) is used for GMR specifications that have a corresponding GSM specification. In this case, the numbers xx and yy correspond to the GSM

32、 numbering scheme. GMPRS-1 03.297 ETSI ETSI TS 101 376-3-19 V2.2.1 (2005-03) 6 - xx.2yy (z = 2) is used for GMR specifications that do not correspond to a GSM specification. In this case, only the number xx corresponds to the GSM numbering scheme and the number yy is allocated by GMR. - n denotes th

33、e first (n = 1) or second (n = 2) family of GMR specifications. A GMR system is defined by the combination of a family of GMR specifications and GSM specifications as follows: If a GMR specification exists it takes precedence over the corresponding GSM specification (if any). This precedence rule ap

34、plies to any references in the corresponding GSM specifications. NOTE: Any references to GSM specifications within the GMR specifications are not subject to this precedence rule. For example, a GMR specification may contain specific references to the corresponding GSM specification. If a GMR specifi

35、cation does not exist, the corresponding GSM specification may or may not apply. The applicability of the GSM specifications is defined in GMPRS-1 01.201 2. GMPRS-1 03.297 ETSI ETSI TS 101 376-3-19 V2.2.1 (2005-03) 7 1 Scope The present document defines the performance requirements for the Mobile Ea

36、rth Station (MES) radio transceiver for the GMR-1 Mobile Satellite System. Requirements are defined for two categories of parameters: Those that are required to provide compatibility among the radio channels, connected either to separate or common antennas, which are used in the system. This categor

37、y also includes parameters providing compatibility with existing systems in the same or adjacent frequency bands. Those that define the transmission quality of the system. 2 References The following documents contain provisions which, through reference in this text, constitute provisions of the pres

The foll

46、owing definitions are expressed within the context of optimal routing: authorized roamer: subscriber whose PLMN is present in roaming agreements at the GS to which the subscriber is attempting to reregister NOTE: Similarly, an Unauthorized Roamer is a subscriber who is denied service at the requeste

47、d GS due to the absence of a roaming agreement between the subscribers home PLMN and the GS to which the subscriber is trying to reregister. BCCH Carrier: RF carrier that carries the FCCH and BCCH. The BCCH carriers may be reused within the system as long as the spot beams in which they are reused a

48、re neither overlapping nor immediately adjacent to one another Broadcast Control Channel (BCCH): carries control information specific to a particular Gateway Station, plus synchronization information by which an MES can locate other BCCHs within the system NOTE: There is a unique BCCH for every Gate

49、way in every spot beam. Cooperating PLMN: PLMN to which an HLR query (SRI/ATI/SRI-SMS) may be composed from the GS for the purpose of OR. Similarly, a Non-Cooperating PLMN is a PLMN to which an HLR query by the GS is prohibited gateway operator: administrative entity that manages a GS and its resources GS (Gateway Station): network entity connected to the terrestrial network that allows network access to and from a user terminal local GS: GS to which the MES registers when not governed by optimal routing concerns NOTE: The selectio
