44、 ETSI ETSI TS 101 376-4-15 V3.4.1 (2017-03) 9GMR-1 3G 25.323Introduction GMR stands for GEO (Geostationary Earth 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 an

45、d supports access to GSM core networks. The present document is part of the GMR Release 3 specifications. Release 3 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 wit

46、h “1“ (V1.x.x). Release 2 specifications have a GMPRS 1 prefix in the title and a version number starting with “2“ (V2.x.x). Release 3 specifications have a GMR-1 3G prefix in the title and a version number starting with “3“ (V3.x.x). The GMR release 1 specifications introduce the GEO-Mobile Radio i

47、nterface 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 to GSM core networks. The GMR release 2 specifications add packet mode services

48、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 access to GSM/GPRS core networks. The GMR release 3 specifications evolve packet m

49、ode services of GMR release 2 to 3rd generation UMTS compatible services. The GMR release 3 specifications introduce the GEO-Mobile Radio Third Generation (GMR-1 3G) service. Where applicable, GMR-1 3G is derived from the terrestrial digital cellular standard 3GPP and it supports access to 3GPP core networks. Due to the differences between terrestrial and satellite channels, some modifications to the GSM or 3GPP standard are necessary. Some GSM and 3GPP specifications are directly applicable, whereas others are applicable with modifications. Similarly, some GSM and 3
