Introduct
44、ion 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 and supports access to GSM core networks. The present document is part
45、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 with “1“ (V1.x.x). Release 2 specifications have a GMPRS 1 prefix in the
46、 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 interface specifications for circuit mode Mobile Satellite Services (M
47、SS) 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 to GMR release 1. The GMR release 2 specifications introduce the GEO
48、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 mode services of GMR release 2 to 3rd generation UMTS compatible servi
49、ces. 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 3GPP specifications do not apply, while some GMR specifications have n
